Kekaha. Waimea. Kauai. Hawaii

PREFACE

Chapter 343, Hawaii Revised Statues (HRS), as amended, Environmental Impact

Statements, requires that a government agency or a private developer proposing to

undertake a project consider the potential environmental impacts of the proposed

project by preparing an assessment. Use of public funds and/or public lands for a

project are among the criteria set forth in Chapter 343, HRS which requires a public

agency to prepare an environmental assessment. The Kapilimao O.S-Million Gallon

Storage Tank and emergency generator building will be constructed and operated with

funds provided by the County of Kauai Department of Water.

This Environmental Assessment (EA) has been prepared to meet the requirements of

Chapter 343, HRS, as amended, and Hawaii Administrative Rules Title 11, State of

Hawaii Department of Health, Chapter 200, Environmental Impact Statement Rules. In

addition, since funds from the State of Hawaii Department of Health Drinking Water

State Revolving Fund (DWSRF) may be used for construction of the Kapilimao 0.5-

Million Gallon Storage Tank, Federal regulations which are identified as "cross cutter"

regulations have been included in this EA.

A Finding of No Significant Impact (FONSI) is determined for the project as shown in

Chapter 6.

1. INTRODUCTION

1.1 Project Background

The County of Kauai, Department of Water (DOW) is the agency responsible for

management, control, and operation of the County's water system. The DOW derives

all of its revenue from water sales with no direct subsidy from, or contributions to the

County General Fund. The DOW performs all functions necessary to collect, treat, and

distribute potable water from the source to the tap. In addition, the DOW performs most

support functions, including accounting, billing, customer service, engineering, planning

and procurement.

Service is provided to residential, commercial, industrial, and institutional users through

11 separate, unconnected water systems spread throughout Kauai from Kekaha to

Haena. Currently, the DOW pumps water from 48 underground wells and tunnels into

43 storage tanks, for delivery to nearly 19,000 accounts through 400 miles of pipeline.

Many of the DOW water systems date back to the plantation era, and some pipelines

are 80-100 years old.

The Kapilimao 0.5-Million Gallon (MG) storage tank will serve the Waimea-Kekaha

water system, the third largest system on Kauai, following the Wailua-Kapaa-Puhi

Lihue-Hanamaulu, and Koloa-Poipu systems.

In anticipation of future water system needs, in March 2001, the DOW issued the Water

Plan 2020 which is to serve as the DOW long-range plan. The Water Plan 2020

included population projections, water demand forecasts, an improvements program for

source, transmission, and storage, and systems analysis for the 11 systems served by

the DOW. Based on the projections in the Plan, between 2000 and 2020, water usage

in the Waimea-Kekaha system will increase about 20 percent.

Water Plan 2020 showed the Waimea-Kekaha system will have a deficit in storage of

500,000 gallons in 2000 which will increase by an additional 100,000 gallons, making

the total deficit of 600,000 gallons in 2020, as shown below.

The existing Kapilimao Valley Well facility will serve as the source of water for the 0.5-

MG tank. The existing well facility does not include an emergency generator to provide

power in the event of an outage from the commercial system serving the Well.

1.2 Purpose and Need

The Kapilimao 0.5-MG Storage Tank will be part of the Waimea-Kekaha water system

which services the Waimea and Kekaha areas of Kauai. The Waimea-Kekaha water

system serves approximately 1,600 customers, which includes the residential and

commercial areas in Waimea and Kekaha, Waimea High School, Waimea Intermediate

School, Kauai Veteran's Hospital, and the Waimea Plantation Cottages.

The primary purpose of the Kapilimao 0.5-MG Storage Tank project is to provide the

water storage needed for the Waimea-Kekaha water system as shown by Water Plan

2020. The storage needs set forth for the system in Water Plan 2020 show the need for

an additional 600,000 gallons of storage in 2000 and another 500,000 gallons of storage

by 2020. The Kapilimao tank is needed to fulfill the long-term projected storage needs

for the Waimea-Kekaha water system.

Since the existing Kapilimao Valley Well facility does not include an emergency

generator, there is a need for an emergency generator at the Well site. The emergency

generator would be a portable trailer-mounted unit and would provide power to the Well

should there be an outage in the commercial power system.

The Kapilimao Storage Tank and emergency generator project is needed to maintain

public health and welfare for the residents of this area of the County. The Kapilimao

Storage Tank project is a public facility to be used by a public agency for public

purposes.

1.3 Project Location and Conditions

1.3.1 Project Location

The Kapilimao 0.5-MG Storage Tank project site is located in the Waimea District of

Kauai, about 1.0 mile north of the Kekaha residential area and approximately 1.25 miles

from the shoreline on the western side of lower Kapilimao Valley in southwest Kauai.

The project site tank is located within TMK: 1-2-002:001, a 12,997.891-acre parcel

owned by the State of Hawaii and under Executive Order to the Agribusiness

Development Corporation. The project site is accessible using agricultural/sugar cane

haul roads and a recently completed paved road which was constructed by the DOW to

reach the Kapilimao Valley Well and pump station site. Figure 1.1 shows the Kapilimao

0.5-MG tank project location map. Figure 1.2 shows the tax map for the area. Figure

1.3 shows project site photographs. Figure 1.4 shows the project site topographic map.

The eXisting Kapilimao Valley Well and pump station facility have been operational from

February 2005. The Well site includes a control building, well, and related equipment

needed to operate the well. The existing well will be the source of water for the 0.5-MG

tank.

1.3.2 Existing Project Site Conditions

Archival research indicates the 0.5-MG tank and emergency generator project sites are

located within lands which, starting from the 1870's through the early 1900s and later,

during the middle of the 20th century, were used for cattle ranching and sugarcane

cultivation. These activities no longer occur within the 0.5-MG tank and emergency

generator project sites and surrounding lands.

The 0.5-MG tank project site is at an elevation of about 178 feet mean sea level (msl)

and will be located about 200 feet northwest of the existing Kapilimao Valley well and

pump station facility which is sited at elevation about 149 feet msl. The lands

surrounding all sides of the 0.5-MG tank project site are undeveloped and vacant. An

approximately 10-foot high rock outcrop lies west of the well and pump station facility

and acts to separate the project site and the well facility.

PROJECT SITE PHOTOGRAPHS Figure 1.3

----~--------------



The 0.5-MG tank project site and much of the surrounding area is covered by degraded

shrub vegetation primarily koa haole, kiawe, Guinea grass, other grasses, and other

introduced species. None of these species is listed as endangered or threatened, or

proposed for listing by the US Fish and Wildlife Service or the State of Hawaii.

The existing Kapilimao Valley Well site occupies an approximately 6,074-square foot

area which has been cleared and fully developed by the DOW.

Two unnamed streams/drainageways are located near the tank project site. One is the

intermittent stream/drainageway that drains Kapilimao Valley. It is generally oriented

north-south and located about 190 feet east of the tank project site and about 22 feet

lower than the finished floor elevation of the tank. Although active only after a heavy

storm event, flows will continue in the drainageway for most times of the year and

provide a source of water for the various species of vegetation which grow along its

path.

The second small unnamed drainageway is oriented west-east and is located about 70

feet north of the 0.5-MG tank project site. This drainageway appears to be a seep that

drains the lower western potion of the Valley. The seep also provides a source of water

for various species of vegetation.

1.3.3 Other Project Site Data

The 0.5-MG tank project site is designated Agricultural by the State Land Use

Commission, Chapter 205, Hawaii Revised Statutes (HRS). According to Chapter 205-

4.5, HRS, major water storage tanks are a permitted use within the Agricultural District.

The County of Kauai zoning designation for the project site is Open. According to the

County of Kauai Code, Chapter 8, Comprehensive Zoning Ordinance, Section 8-8.3,

utility installations would be classified as a use and structure for which a Use Permit is

required. Further, since a Use Permit is required, a Class IV Zoning permit is also

needed. The Use Permit and Class IV Zoning permit are approved by the County of

Kauai Planning Commission.

The project site is not located within the County of Kauai Special Management Area

(SMA).

1.4 Previous Environmental Documentation

In March 2000, the DOW issued a Final Environmental Assessment (EA) for the

Kapilimao Valley Well and Transmission Main. This Final EA addressed the

development of an exploratory well for water production purposes and construction of

transmission main to connect to the existing distribution system. The well and

transmission main project was funded under the Cooperative funding Agreement

between the County of Kauai Housing Agency and the DOW. The development costs

were partially supported by Community Development Block Grant funding and by the

DOW.

1.5 Project Description

The 0.5-MG tank floor will be sited at about elevation 178 feet mean sea level (msl) and

will be located about 200 feet northwest of the existing Kapilimao Valley Well and pump

station complex sited at an elevation of about 149 feet msl.

The Kapilimao O.S-MG tank project will include the following

•

•

• Cutting and excavation of about 24 feet of hillside to provide an approximately

100-foot diameter pad for the tank and related improvements, including a

chlorination reservoir and transmitter vault. The total area of the cutting and

excavation will be about 0.6 acres-for the O.S-MG tank. Figure 1.S shows the

site plan.

Construction of a O.S-MG reinforced concrete tank, which will be about 20 feet

high with an outer wall diameter of approximately 72 feet and inner wall diameter

of 69 feet. Conventional spread footings placed directly on medium hard to hard

basalt will be used to support the tank. The tank floor will be at 178 feet msl and

the spillway at 196 feet msl, the same overflow elevation as the existing Paua

Valley water tanks, located approximately 2,SOO feet to the west.

Construction of a 10-foot wide asphalt concrete (AC) paved perimeter service

road around the tank.

1-10



Kapilimao O.5-Mil/ion Gallon Storage Tank Environmental Assessment Kekaha, Waimea, Kauai, Hawaii

•

•

•

Construction of pipelines and necessary valves to connect the tank to the

Kapilimao Valley Well (State Well No. 5841-02).

Construction of a 6-foot high perimeter chain link security fence for the tank pad.

Construction of an underground drainage system and drain inlets near the east

side of the tank to intercept storm flows from the western slopes of Kapilimao

Valley. The underground drainage system will outlet into an approximately 32-

foot wide by 45-foot long (1,440 square feet) detention basin which will retain

sediment from runoff prior to discharge into a trapezoidal-shaped outlet east of

the 0.5-MG tank. The outlet will direct flows to the unnamed stream draining the

northern portions of Kapilimao Valley.

• Construction of a 12-foot wide by approximately 250-foot long asphalt concrete

(AC) paved access driveway to connect the tank with the well and pump station

complex.

No exterior lighting will be constructed as part of the 0.5-MG tank. The 0.5-MG tank will

be of medium to dark toned earth or natural colors which will visually blend with the

surrounding environment.

The 0.5-MG tank will be constructed of cast-in-place reinforced concrete. The outer wall

diameter will be approximately 72 feet and the inner wall diameter approximately 69

feet. This will result in a tank wall thickness of about 18 inches. The interior of the tank

will include 4 cast-in-place, 20-inch square columns placed 12 feet on center from the

center pOint of the tank. Concrete tanks of similar design have historically been used in

a number of locations, including in Hawaii. The design is intended to preclude structural

failure and possible flooding of the surrounding area.

A geotechnical investigation was included as part of the design of the O.5-MG tank. The

geotechnical investigation indicated permanent cut slopes may be designed for

gradients of 1 H: 1 V or flatter. The geotechnical investigation indicated benches are not

required for slopes cut into basalt 50 feet or less in height. Thus, the excavation of

about 24 feet of hillside described above will not require bench cuts.

1-13


The 0.5-MG tank project site is not located near developed areas where homeowners

could be impacted. Since there is no development in the immediate area, a rockfall

study was not required as part of the planning or design. The design drawings, notes,

and specifications will state that the contractor is to remove any loose rocks in the area

of construction to ensure any development in the future would not get impacted by

falling rock. The 1.0 mile distance from the nearest residential area should provide a

buffer zone from the 0.5-MG tank project site.

Since the project site is under the control of the Department of Water, the County of

Kauai Department of Public Works will exempt the grading permit requirements for the

tank project site and driveway access. However, to ensure protection of the surrounding

area, construction inspections will be performed by the DOW to ensure that Best

Management Practices (BMPs) are complied with at all times during construction of the

project. Grading and erosion control plans, including the BMPs that the contractor must

use, will be part of the design drawings. The BMPs will include the use of silt fences

and rock filter berms to control runoff and sediment from the project site.

In addition to the tank, the following construction will also be done at the existing 6,074-

square foot Kapilimao Valley Well site located about 200 feet south of the 0.5-MG tank.

The construction will include:

• Clearing, cutting and grading an additional 3, 192-square foot area for expansion

of the well site on the north side. See Figure 1.5.

• Development of a 1,060-square foot expansion area, which will provide a total

well site area of approximately 8,134 square feet.

• Construction of a 375-square foot (15 feet by 25 feet) above ground building to

contain a trailer-mounted emergency generator and related fuel storage tank in

the 1,060-square foot expansion area. The generator building will be north of

the existing pump control building at the Well site.

• Construction of a security fence around the emergency generator building.

No exterior lighting will be constructed as part of the emergency generator building.

1-14





During construction, silt fences will be used to control sediment runoff from the 0.5-MG

tank and emergency generator construction areas and to prevent sediment being

carried into the adjacent unnamed drainageway. In addition, a coarse rock pad will be

sited at the lower end of the 12-foot wide access driveway to remove material from

construction equipment and vehicles as they leave the construction area. The design

drawings and speCifications will state the contractor must use the BMPs at all times to

prevent damage by sedimentation or erosion to the nearby water course, natural areas

and adjacent properties. See Figure 1.5.

Based on preliminary estimates, a total of 7,500 cubic yards (CY) of cutting and

excavation will be required to prepare the 0.5-MG tank site. The site plan design shows

about 4,700 CY of the excavated material will be used on the site from fill material or for

construction of the detention basin. The remaining excavated material, about 2,800 CY,

will be moved off-site to other locations which could use the material or to an approved

landfill. Based on an end dump trailer capacity of about 18 CY - the approximate size of

a trailer typically used to haul excavated material - a total of about 150 -160 truck loads

of material will have to be moved off site.

An existing paved access road, constructed by the DOW as part of the Kapilimao Well

facility will also provide access to the 0.5-MG tank

A temporary stockpile area has been identified for temporarily storing the excess

excavated material. The temporary stockpile area will be about 100 feet by 100 feet and

has been sited south of the existing Kapilimao well site and west of the pave access

road. The stockpile site will also include necessary silt fencing to control surface runoff

from the site.

As part of the Draft EA review and comment, the County of Kauai Department of Public

Works has stated the County's Kekaha Sanitary Landfill could use the excess material

as cover material. A grading permit will not be required for disposal of the excess

material at the Kekaha Landfill.

1-15


1.6 Water Treatment

The existing Kapilimao Well pump system provides the chlorination necessary for the

water in the system. No further water treatment will be needed at 0.5-MG tank project

site.

1.7 Project Operation

No DOW personnel will be assigned to daily operation of the Kapilimao tank project site.

However, DOW personnel will visit the project site about three times per week to

conduct tests, perform maintenance, and to clean the surrounding area.

1.8 Preliminary Cost Estimate

The budgeted construction cost for the Kapilimao 0.5-MG tank project is approximately

$4.0 million, to be funded by DOW. Funds from the State of Hawaii Department of

Health Drinking Water State Revolving Fund (DWSRF) may be used for construction the

0.5-MG tank project.

1.9 Project Schedule

Construction is expected to start in mid-2008 and should require about 12 months to

complete.

1-16




2. DESCRIPTION of EXISTING ENVIRONMENT

2.1 Geology and Soils

The Island of Kauai is the oldest of the major islands in the Hawaiian chain. The Kauai

Volcanic shield built itself off the ocean floor approximately two to four million years ago.

Rock formations belonging to this original shield are part of the Waimea Canyon

Volcanic Series, a major portion of which are the thin lava flows of the Napali formation.

Maps by the U.S. Soils Conservation Service (now Natural Resources Conservation

Service), within the "Soil Survey of Islands of Kauai, Oahu, Maui, Molokai, and Lanai,

State of Hawaii, August 1972" classify the soil at the project site and valley slopes as

Waiawa extremely rocky clay (WJF) which is grouped in the Waiawa soil series and

consists of well-drained, very shallow, extremely rocky soils on uplands on the island of

Kauai. These soils developed in colluvium and in material weathered from basic

igneous rock.

A thin layer of granular heavy clay loam (2- thick) is underlain by dark reddish-brown

clay about 12 inches thick. The substratum is hard rock. Surface soil permeability is

moderate to moderately slow. Runoff is very rapid, and the erosion hazard is severe.

Roots penetrate to bedrock and follow cracks in the rock.

In April 2007, geotechnical investigations were undertaken at the project site to identify

design considerations for the 0.5-MG tank. Four exploratory borings were drilled to

depths ranging from approximately 13 to 44 feet. In addition, laboratory analysis was

done on the soil samples taken during the borings.

The findings of the April 2007 geotechnical study show that the three borings drilled

along the slope encountered gray moderately weathered basalt in fractured, vesicular,

and medium hard to hard condition to the maximum depths drilled. The weathered

basalt was covered by a thin surface layer of brown clayey silt with sand, gravel, and

cobbles.

The fourth boring, taken near the pump station site, found surface soil classified as

reddish brown clayey silt with sand and gravel. The clayey silt was in stiff condition to a

2-1


depth of about 3.5 feet. Moderately weathered basalt in a highly fractured, vesicular,

and medium hard condition was found to underlie the clayey silt.

No groundwater or seepage water was encountered during the exploratory borings.

The County of Kauai uses the 1997 Uniform Building Code (UBC). Originally enacted in

1927, the UBC was developed by the International Code of Building Officials to guide

construction of buildings, structures, and facilities throughout the US. The State of

Hawaii and the county governments, including the County of Hawaii, have adopted the

UBC as the applicable code for constructing buildings, structures, and facilities.

In addition, the UBC assigns a seismic zone to guide design. The County of Kauai is

assigned seismic zone 1 in the 1997 UBC. Seismic zone 1 indicates a relatively low

level of potential seismic hazard.

The purpose of the seismic provisions in the UBC is primarily to safeguard against major

structural failures and loss of life, not to limit damage or maintain functions. Structures

are to be designed and constructed at a minimum to resist the effects of ground motion

from seismic events. The site seismic hazard characteristics in the UBC are based on

the seismic zone and proximity of the site to active seismic sources.

2.2 Water Resources and Flood Hazard

The principal sources of groundwater on the island of Kauai are from the Napali

Formation of the Waimea Canyon volcanic series. This volcanic series is typically highly

permeable and yields water readily to wells as experienced by the Kekaha-Waipio and

Paua Valley wells. The Koloa Volcanic series, in contrast, tends to be poorly to

moderately permeable and offers limited yields. The 0.5-MG tank project site is located

in the Napali Formation series.

Groundwater in the region is used for domestic (DOW) and irrigation (Kekaha Sugar

Company). Wells in the vicinity are located where the fresh water lens is thicker. The

DOW's Paua Valley well (Well #5942-01) is equipped with a 500 gallon per minute

(gpm) pump. The Waipao well "B" (Well #5943-02) is equipped with a 700 gpm pump.

The existing Kapilimao Well is equipped with a 700 gpm pump. However, pumping is

limited withdrawal of about 400,000 gallons during an average day.

2-2




There are two surface water sources near the 0.5-MG tank project site. The US

Geological Survey (USGS) topographic map shows the unnamed stream to be

intermittent. This unnamed intermittent stream drains the northern end of Kapilimao

Valley and is active only after a heavy storm event. This unnamed stream is about 190

feet east and about 22 feet below the finished floor elevation (178 msl) of the 0.5-MG

tank project site.

The topographic map shows the unnamed stream flows into a series of above ground

ditches which were developed to irrigate the sugar cane fields located between the

southern end of Kapilimao Valley and Kehaka. The topographic map shows flows from

the unnamed stream would flow into the Waimea Ditch and into a series of ditches

which eventually flow into the Pacific Ocean near Oomano Point.

In addition, the site survey of the project site showed there is a small drainageway

draining the western slope of hillside in the vicinity of the 0.5-MG tank project site. This

drainageway is not identified on the USGS topographic map and appears to be seep

from the hillside. This seep is about 70 feet north of the tank project site and joins the

unnamed intermittent stream.

The emergency generator site also does not contain surface water sources.

The Waimea-Kekaha area lies on the leeward side of Kauai and has a mean annual

rainfall of about 22 inches. The relatively sparse rainfall would limit the flows in the

unnamed intermittent stream.

The O.5-MG tank and emergency generator project sites are located in Zone X on the

Federal Emergency Management Flood Insurance Rate Map (FIRM) Map Number

1500020252E, Map Revision September 16, 2005. Zone X is defined as: "area

determined to be outside of the 0.2% annual chance floodplain." This indicates the

project site is not located within the flood hazard area of a 500-year flood plain. Thus,

the project site is not subject to flooding. See Appendix A.

The Department of the Army has confirmed this flood hazard information, as part of the

Draft EA review. See Appendix E.

2-3


The State of Hawaii Department of Land and Natural Resources Engineering Division,

as part of the Draft EA review, stated that the National Flood Insurance Program does

not have any regulations for development in Zone X. See Appendix E.

2.3 Agricultural Lands

In 1975, the US Department of Agriculture Soil Conservation Service (now Natural

Resources Conservation Service) initiated a nationwide inventory of important

farmlands. The inventory included three categories: "prime", "unique", and "other

farmlands of state-wide and local importance". This classification was later adopted by

the State of Hawaii Department of Agriculture under the title "Agricultural Lands of

Importance to the State of Hawaii" (ALlSH).

The ALiSH system defines "prime agricultural land" as land best suited for food, forage,

and timber crops. "Unique agricultural land" is defined as land other than prime, used

for the production of high-value food crops. "Other agricultural land" is defined as land

used for the production of food, feed, fiber and forage crops, but not classified as

"prime" or "unique".

According to the ALiSH system, the O.5-MG tank and emergency generator project sites

are not classified, indicating that the lands are not the highest classification for

productivity and high yield. Most of the nearby surrounding lands in Kapilimao Valley

are not classified in the ALiSH maps.

2.4 Hazardous Waste

The O.5-MG tank and emergency generator project sites have not been previously

cleared or developed. No structures, buildings, facilities, or underground storage tanks,

or other uses which might contain hazardous materials have been constructed on the

project site.

2-4




2.5 Biological Resources

Except for the existing developed pump station site, vegetation on the O.5-MG tank

project site and surrounding area can be generally described as highly degraded

lowland shrub vegetation of introduced species. The typically found species include koa

haole, kiawe, Guinea grass, and other grasses. The species can be found along the

unnamed stream and seep. The introduced species are not US Fish and Wildlife

Service (USFWS) or State of Hawaii Department of Land and Natural Resources

(DLNR) listed or proposed threatened or endangered species.

Fauna

The O.5-MG tank and emergency generator project sites do not contain botanical

species which would support a wildlife population of birds or mammals. Although not

specifically noted, the project site would likely contain various species of feral animals,

including goats and pigs. The presence of water in the unnamed stream and seep

would attract animals to the area of the project site. None of the species which might

occasionally visit the project site would be considered a USFWS or DLNR listed or

proposed threatened or endangered species of fauna.

2.6 Traffic

The O.5-MG tank and emergency generator project sites are located north of Kekaha,

about 1.1 miles north or mauka of Kaumualii Highway (State Route 50). the main

roadway serving the southern portion of Kauai. An existing former canefield haul road

connects Kekaha to the southern edge of Kapilimao Valley. From that point, the DOW

access road provides access to the previously constructed Kapilimao well site. Traffic to

the O.5-MG tank project site would be limited to DOW-related activities.

2.7 Air Quality

The O.5-MG tank and emergency generator project sites are located in the Waimea

District on the southern portion of Kauai, an area characterized by a relatively low level

of residential and commercial development and almost no industrial-type facilities. A

2-5


low level of development generally indicates an absence of stationary and mobile

sources of emissions which could affect ambient air quality.

Although the air quality in the southern portion of Kauai is characterized by low levels of

pollutants, the exception would be seasonal dust created during agricultural planting and

harvesting. During these periods, dust would be the primary source of air pollution.

Vehicle traffic along Kaumualii Highway would be the primary source of mobile

emissions near the project site. However, traffic volumes tend to be relatively low along

this portion of the highway.

2.8 Noise

The area surrounding the project site does not include residences or other uses which

could be considered noise sensitive. There are no commercial or industrial

developments in the area of the project site. As a result, there is an absence of

stationary noise sources.

The main noise source in the vicinity of the project site is vehicle traffic on Kaumualii

Highway which is about 1.1 miles south of the project site. Since vehicle traffic on both

roads in the vicinity of the project site is relatively light, noise generated by vehicle traffic

should not be significant.

The closest residential area is on the eastern edge of Kekaha, about 1.0 miles south of

the 0.5-MG tank project site.

2.9 Archaeological and Cultural Resources

Archival research indicates the 0.5-MG tank and emergency generator project sites are

located within lands which, starting from the 1870's through the early 1900s and later,

during the middle of the 20th century, were used for cattle ranching and sugarcane

cultivation. These activities no longer occur within the 0.5-MG tank and emergency

generator project sites and surrounding lands.

In April 2007, an Archaeological Field Inspection was conducted for the 0.5-MG tank

project site. The Field Inspection was conducted to determine the presence or absence

2-6





of surface sites or features in the Area of Potential Effects and to determine the

potential for uncovering subsurface sites and features.

The field inspection consisted of a full systematic pedestrian survey of the Area of

Potential Effects (APE) defined as the project site plus 100 meters beyond the limits of

the planned work and limited archival research. The Field Investigation is in

Appendix B.

The field inspection showed no cultural surface architecture or deposits were found on

the 0.5-MG tank project site or the APE. The field investigation and archival research

indicate there are no known traditional or historic properties in the APE. Based on these

findings and the results of previous work done for the Kapilimao Valley Well site, no

further archeological work was recommended. See Appendix B.

The emergency generator building project site is adjacent to the existing Kapilimao

Valley Well facility. In October 1998, the Well facility and adjacent area, including the

emergency generator building area, were included in the archaeological investigation

conducted at that time. The archaeological investigation failed to yield any traditional or

early historic archaeological resources. Based on the findings of the 1998 investigation

work, no further archaeological work was recommended. See Appendix C.

2.10 Cultural Impact Assessment

On April 26, 2000, the Governor approved House Bill No. 2895 H.D.1 as Act 50 which

amended Chapter 343 Hawaii Revised Statutes (HRS) to require a cultural impact

assessment be included in the preparation of an Environmental Impact Statement!

Environmental Assessment.

According to the Guidelines for Assessing Cultural Impacts established by the Hawaii

State Office of Environmental Quality Control (OEQC 1997):

"The types of cultural practices and beliefs subject to assessment may include subsistence, commercial, residential, agricultural, access-related, recreational, and religious and spiritual customs. The types of cultural resources subject to assessment may include traditional cultural properties or other types of historic sites, both manmade and natural, which support such cultural beliefs.·

2-7


2.11 Infrastructure

2.11.1 Water

The project site is currently served by the County of Kauai Department of Water system.

2.11.2 Sewer

The project site is not served by the County of Kauai sewer system. No toilet facilities

will be constructed on the project site. Thus, the 0.5-MG tank will not require

wastewater services from the County of Kauai or use an on-site system for treatment or

disposal of wastewater.

2.11.3 Electrical

Kauai Island Utility Cooperative (KIUC) provides commercial electrical power to this area

of Kauai. KIUC provides existing electrical service to the Kapilimao well site via

overhead power lines located on the well access road.

2.12 Visual Considerations

The 0.5-MG tank project site is located at the lower elevations of Kapilimao Valley,

within an undeveloped area characterized by lowland shrub vegetation of introduced

species common to the southern portion of Kauai. The existing Kapilimao Valley Well

facility is only visible for a short distance from the well access road, which is closed to

public use.

The closest residential uses to the 0.5-MG tank project site are located in Kehaka, about

1.0-mile to the south and about 120 feet or more below the tank elevation. The existing

vegetation and terrain obscures views of the 0.5-MG tank project site.

Kaumualii Highway, the main travel route for this area of Kauai, is about 1.1 miles to the

south. The existing vegetation and terrain obscure views of the 0.5-MG tank and

emergency generator project sites from the Highway.

2-8




2.13 Socioeconomic Considerations

The 0.5-MG tank and emergency generator project sites are located on the South Shore

of Kauai and will service the Kekaha and Waimea Census Designated Place (COP).

The 2000 Census provides information about the COPs, which is a designation used by

the US Census Bureau to collect data on a community basis. The State and the County

of Kauai do not provide similar information for their projections of population.

A comparison between the Kekaha and Waimea COPs and the County of Kauai shows:

1) The combined Kekaha and Waimea COPs represents about 8.5 percent of the total

County population; 2) The average total percentage in the labor force is lower in

KekahaIWaimea than in the County. 3) The percentage of white population in the

KekahaIWaimea COPs is about half the percentage of the County; 4) The percentage

of Native Hawaiians in the KekahalWaimea COPs is slightly higher than in the County;

5) The median family income for the KekahalWaimea COP is about 7.3% lower, on

average, than for the rest of the County; and 6) The education level in terms of percent

high school graduate or equivalent is higher in Waimea/Kekaha than in the County. See

below.

3. DESCRIPTION of ENVIRONMENTAL IMPACTS and MITIGATION

MEASURES

3.1 Geology and Soils

The O.S-MG and tank emergency generator building will be designed and constructed to

meet the requirements set forth in the 1997 UBC. This will ensure that the structures

can meet the seismic loadings established for Zone 1. This will also ensure that the

geological conditions at the project site do not adversely affect the reservoir and related

facilities.

The O.S-MG tank project site will require cutting and grading and construction of a

footing to provide a base for the tank. The cutting will disturb surface and subsurface

soils which will be removed to an approved landfill or other approved site. Although

cutting the embankment will remove the soil, construction of the retaining wall and tank

base will be graded to match the existing surrounding grade which will minimize adverse

impacts to the surrounding area.

As previously discussed, a geotechnical investigation was included as part of the design

of the O.S-MG tank. The geotechnical investigation indicated permanent cut slopes may

be designed for gradients of 1H:1V or flatter. The geotechnical investigation indicated

benches are not required for slopes cut into basalt SO feet or less in height. Thus, the

excavation of about 24 feet of hillside described above will not require bench cuts.

Although the Kapilimao O.S-MG tank project site is located on a hillside, the nearest

residential development is about 1.0 mile from project site. The area near the tank will

be cut and graded to match existing grades. In addition, the O.S-MG tank project site is

not located near developed areas where homeowners could be impacted. Since there is

no development in the immediate area, a rockfall study was not required. The design

drawings, notes, and specifications will state that the contractor is to remove any loose

rocks in the area of construction to ensure any development in the future would not be

impacted by falling rock. The 1.0 mile distance area between the O.S-MG tank project

site should provide a buffer zone from the nearest residential area.

3-1


3.2 Water Resources and Flood Hazard

Temporary erosion control measures will be used during construction to prevent runoff

to nearby areas, including to the unnamed intermittent stream east of the project site

and the small drainageway!seep north of the project site. These mitigation measures

will include placement of a silt fence downslope of the 0.5-MG tank and emergency

generator project sites to prevent surface runoff into adjacent areas. The silt fence will

contain surface flows within the project site during the construction period.

During construction, silt fences will be used to control sediment runoff and to prevent

sediment being carried into the adjacent unnamed drainageway. In addition, a coarse

rock pad will be sited at the lower end of the 12-foot wide access driveway to remove

material from construction equipment and vehicles as they leave the construction area.

The design drawings and specifications for the project will state the contractor must use

the BMPs at all times to prevent damage by sedimentation or erosion to water courses,

natural areas and adjacent properties.

In addition, to control erosion and runoff from the excavated and graded area,

hydromulch covered with erosion control blankets will be used. This area is about 0.25

acres and will also include temporary irrigation until the vegetation has become

established. Once established, the vegetation will become similar to the surrounding

area.

There are no surface water sources on the 0.5-MG tank project site. The 0.6-acre area

would be cleared, excavated, and graded to construct a pad for the 0.5-MG tank. Other

work will include construction of underground drain lines and outlets near the 0.5-MG

tank and at the start of the 12-foot wide access driveway. During construction, a silt

fence will be constructed south of the tank site and access driveway to contain surface

runoff from flowing further to the south and into the unnamed stream. In addition, the

check dams will be placed at the two drainage outlets. The check dams would consist

of aggregate-filled bags which would form a small dam to retain sediment in the surface

flows. The silt fencing will also extend to the area of the emergency generator building

to contain flows during construction.

The County of Kauai Department of Public Works will exempt the requirement for a

grading permit for the 0.5-MG tank project site and driveway access. Grading and

3-2




erosion control plans, including the Best Management Practices (BMPs) that the

contractor must use, will be part of the design drawings. The BMPs will include the use

of silt fences and rock filter berms to control runoff and sediment from the project site.

Construction inspections will be performed by the Department of Water who will also be

monitOring the grading.

The 0.5-MG tank project site is located at elevation 178 feet mean sea level. The area

between the project site and residential area is a sloping plain which becomes a board

plain of formerly used sugar cane fields. The 1.0 mile distance and intervening

topography should provide protection for the residential areas to the south.

The 0.5-MG tank is located at the lower portion of Kapilimao Valley and about 200 feet

west of an unnamed stream that drains the Valley. The USGS topographic map

appears to show this unnamed stream flows into the ditch system which was used for

the former sugar cane fields that were located in the area between the Valley and

Kekaha. See Figures 1.1 and 1.2.

A Drainage Study was done as part of the design work related to the 0.5-MG tank

drainage system, detention basin, and related drainage outlets. The runoff from a 2-

year, 1-hour storm event was calculated for existing conditions and for post construction

conditions. The calculated runoff for existing conditions was 6.07 cubic feet per second

(cfs) and for post construction 6.86 cfs. The post construction condition includes runoff

to the detention basin and sheet flow to the surrounding area. The detention basin has

been sized to retain this increased runoff. The grading will promote sheet flow to reduce

erosion due to concentrated flow. The change in runoff of 0.79 cfs should not affect the

characteristics of the unnamed stream located east of the tank. See Figure 1.5.

The topographic survey shows the bottom of the unnamed stream to be at around

elevation +140 feet near the tank site. The tank floor elevation is at +178 feet, or about

35-40 feet above the stream elevation. This difference in elevation should be such that

the tank will not be affected by flows from the unnamed stream except in the most

extreme storm event. See Figures 1.4 and 1.5.

The 0.5-MG tank project site is located in Zone X, according to FIRM 1500020252E,

September 16, 2005. The County of Kauai Department of Public Works Building

3-3


Division confirmed the 0.5-MG tank project site is located outside the Special flood

Hazard Area. See Appendix E.

The residential area of Kekaha is about 1.0 mile from the tank project site. Given, the

ditch system and the distance of the residential area, and calculated change in runoff,

the runoff from the 0.5-MG tank project site should not affect the residential areas.

Once construction has been completed, natural drainage patterns in the area

surrounding the tank site would continue to direct flows to the east into the unnamed

intermittent stream. The underground drain inlets near the tank and the swales along

the access driveway would also direct the collected flows to the unnamed intermittent

stream. The relatively sparse rainfall would mean a limited runoff would be coming from

the tank site and access driveway. Thus, there will be limited discharges from the

project site flowing to waters of the US, or waters of the State of Hawaii.

3.3 Agricultural Lands

The 0.5-MG tank project site will occupy about 15,000 square feet, about 0.35 acres.

Removal of this vacant and undeveloped not classified agricultural land in the

Department of Agriculture "Agricultural Lands of Importance to the State of Hawaii

(ALlSH) map would not adversely affect the total land available for agricultural uses in

this area of Kauai.

Construction of the emergency generator building will remove an area of 1 ,060 square

feet of land from its present vacant and undeveloped use. Removal of this not classified

vacant and undeveloped agricultural land would not adversely affect the total land

available for agricultural uses in this area of Kauai.

3.4 Hazardous Waste

Construction of the 0.5-MG tank will require clearing and excavation to set the

foundation and spread footings. Since the project site does not contain hazardous

materials, there will be no adverse impacts from the clearing and excavation during

construction of the 0.5-MG tank.

3-4




Construction of the emergency generator building will also require also require minor

clearing and excavation to set the foundation. Since the emergency generator site does

not contain hazardous materials, there will be no adverse impacts from the clearing and

excavation of the emergency generator building.

The 0.5-MG tank project site will not include a facility to add chlorine or other chemicals

to the tank.

3.5 Biological Resources

Construction of the 0.5-MG tank will require removal of the surface vegetation from the

project site to construct the tank foundation and related facilities and the access

driveway. Removal of the surface vegetation will not create a significant adverse impact

to the botanical resources of this area of Kauai. No plants listed or proposed for listing

as endangered or threatened by USFWS or the State of Hawaii are found on the 0.5-

MG tank and emergency generator building project sites. The State Division of Forestry

and Wildlife has indicated they have no objections to the 0.5-MG tank project. See

Appendix E.

Fauna

The development of the 0.5-MG tank project site will remove vegetation which could be

used as habitat by various speCies of feral animals, including goats and pigs. However,

since these species are not considered threatened or endangered, removal of this

habitat, an area of about 0.6 acres, will not result in adverse impacts to species currently

listed or proposed for listing as endangered or threatened by the USFWS or the State of

Hawaii.

No exterior lighting is proposed in conjunction with the 0.5-MG tank or the emergency

generator building. Since no exterior lighting is proposed, development of these

facilities will not result in adverse impacts to either Hawaiian Petrels or Newell's

Shearwaters which might be in the area.

3-5


3.6 Traffic

Traffic impacts related to construction activities will occur while equipment and materials

are moved to the project site and the excavated material must be moved off site. Based

on the need to remove about 2,800 cubic yards (CY) of excavated material off site and

an end dump trailer capacity of about 18 CY, a total of about 150-160 truck loads of

material will have to be moved off site.

At this time, the off-site location for this material has not been determined. The off-site

location will be determined by the contractor selected by the DOW for construction.

Unless the material is disposed nearby, the truck traffic will have to use Kumauni

Highway (State Route 50) to reach an off-site disposal location. However, this additional

traffic will be short-term, occurring only during the 12-month construction period. This

should not create an adverse impact to traffic on Kumauni Highway or the former

canefield haul road leading to the project site as traffic volumes on these roadways are

relatively low.

Once construction has been completed, no personnel will be assigned on a daily basis

to the 0.5-MG tank project site. DOW personnel will visit the project site to inspect the

station and tank and perform maintenance service. An average of about three trips per

week will occur to conduct the necessary tests and perform maintenance on the

equipment at the project site. This level of activity will not create an adverse effect to

traffic on Kaumualii Highway or the nearby streets. The State Department of

Transportation has indicated by letter that it expects no discernible impacts to DOT

facilities from the project. See Appendix E.

3.7 Air Quality

Potential short-term adverse air-quality impacts during the construction phase include:

1) generation of fugitive dust during excavation, cutting and grading; and 2) exhaust

emissions from on-site construction equipment and from construction workers' vehicles

traveling to and from the project site. These adverse impacts will be short-term during

the period of construction.

Preliminary plans show a total of 2,800 cubic yards (CY) of excavated material will have

to be moved off-site to other locations which could use the material or to an approved

3-6



Kapilimao O.S-Million Gallon Storage Tank Environmental Assessment


landfill. Based on an end dump trailer capacity of about 18 CY -- the approximate size

of a trailer typically used to haul excavated material -- a total of about 150-160 truck

loads of material will have to be moved off site.

Construction activities must comply with provisions of Chapter 11-60.1, Hawaii

Administrative Rules (DOH), "Air Pollution Control- and, with respect to fugitive dust,

Section 11-60.1-33. In addition, the 0.5-MG project site to be cleared is an area

approximately 0.6-acre (26,100 square feet) which will mean a relatively small area of

disturbance. The construction notes to the plans will state that the contractor must

maintain the areas within and without the project limits free from dust which would cause

hazards to the work and to other persons or property. The specifications will also state

the contractor will be permitted to use accepted methods for dust control such as

enclosure and filtering. It is expected that the contractor will comply with State

regulations and provide adequate means to control dust during the various phases of

construction.

lastly, although the contr~ctor will have to meet the requirements of Chapter 11-60, it

should be noted there are no land uses near the project site which would be affected by

dust from construction activities. The closest residential areas are located over one mile

away from the 0.5-MG tank site in Kekaha.

Once construction has been completed, operation of the 0.5-MG tank will involve visits

about three times a week by DOW personnel who will perform periodic maintenance

and testing of equipment and systems. This level of activity will not generate sufficient

traffic to adversely affect air quality in the area.

3.8 Noise

Construction activities such as grading, excavating for footings and foundations, and for

underground piping and the transmission main will create noise. The equipment used

for these activities typically include pick-up trucks, excavators, backhoes, concrete

delivery trucks, water tank trucks, hydraulic cranes, and forklifts. Vehicle noise will be

short-term, limited to daytime hours throughout the period of construction. Once

construction has been completed, construction noise impacts will no longer occur.

3-7


The County of Kauai zoning designation for the project site is Open. Title 11 Hawaii

Administrative Rules State of Hawaii Department of Health Chapter 46, Community

Noise Control identifies maximum permissible sound levels for classes of zoning districts

using the zoning established by the counties. According to Chapter 46, the maximum

permissible sound level at any point at or beyond the property line is 55dBA for daytime

and 45dBA for nighttime for zoning district Class A, areas equivalent to lands zoned

conservation, residential, preservation, public space, open space, or similar type. The

maximum permissible sound level shall apply in a manner deemed appropriate by the

Director of the Department of Health.

Once construction has been completed, noise will be generated periodically by DOW

personnel vehicles and others who would be visiting the project site. This level of

activity will not create significant adverse noise impacts to adjacent or surrounding

properties.

The 0.5-MG tank will not contain pumps or equipment that could be considered a noise

source.

The emergency generator will be housed in a concrete masonry building which will

include necessary noise insulation. This will mitigate noise during testing and operation

of the emergency generator. In addition, the closest residential area is about 1.0 mile

from the generator building. This distance will ensure that noise does not adversely

affect the residential area.

3.9 Archaeological and Cultural Resources

On April 20, 2007, the State of Hawaii Department of Land and Natural Resources

Historic Preservation Division (SHPD) accepted the results of the field investigation and

letter report. See Appendix B.

On May 22, 2007, the Historic Preservation Division issued a determination letter

indicating that "an acceptable archeological assessment or inventory survey found no

historic properties". Thus, the Historic Preservation Division concluded that "no historic

properties will be affected" by this undertaking. Appendix A shows the DNLR Historic

Preservation Division letter.

3-8


I I , I I I I , I I I I t I I I , I I


On October 15, 2007, as part of the Draft EA comment process, the Department of

Land and Natural Resources Historic Preservation Division replied that they believe "no

historic properties will be affected" by the project. See Appendix E.

Based on the 1998 archaeological investigation of the Well site, on November 23, 1999,

the Historic Preservation Division issued a determination letter that the Well project

would have "no effect" on significant historic sites. See Appendix C.

As an additional mitigation measure and as a condition of the May 22, 2007 Historic

Preservation Division letter, the general notes in the contract drawings will state that

should archaeological sites such as walls, platforms, pavements or mounds, or remains

such as artifacts, burials, concentrations of shell or charcoal be encountered during

construction activities, work shall cease immediately and the find shall be protected from

further damage. The contractor shall immediately contact State Historic Preservation

Division, who will assess the significance of the find and recommend an appropriate

mitigation measure, if necessary.

On October 15, 2007, the Historic Preservation Division again stated: "In the event that

historic resources, including human skeletal remains, are identified during the

construction activities, all work needs to cease in the immediate vicinity of the find, the

find needs to be protected from additional disturbance, and the State Historic

Preservation Division, Kauai Section, needs to be contacted immediately at

808.742.7033." This requirement will be included in the contract drawings.

3.10 Cultural Impact Assessment

As part of the cultural impact assessment process, individuals and/or groups who have

knowledge of traditional practices and beliefs associated with a project area or who

know of historical properties within a project area are sought for consultation.

Individuals who have particular knowledge of traditions passed down from preceding

generations and a personal familiarity with the project area are invited to share their

relevant information. Often people are recommended for their expertise, and indeed,

organizations, such as Hawaiian Civic Clubs, the Island Branch of Office of Hawaiian

Affairs, historical societies, Island Trail clubs, and Planning Commissions are depended

upon for their recommendations of suitable informants.

3-9

Kapilimao O.5-Million Gallon Storage Tank Environmental Assessment Kekaha. Waimea. Kauai. Hawaii

For the O.S-MG tank, letters were sent to individuals and organizations whose

jurisdiction includes knowledge of the area. The letters briefly outlined the development

plans along with maps of the project area and an invitation for consultation.

Consultation was sought from the Department of Hawaiian Homelands, DLNR State

Parks Division, the Office of Hawaiian Affairs, Oahu Branch and Kauai Island Branch;

and the Kauai Burial Council. The Department of Hawaiian Homelands and State Parks

responded with letters indicating they had no comments on the project. Appendix D

contains the Cultural Impact Assessment.

If cultural resources are identified based on the information received from these

organizations and additional informants, an assessment of the potential effects on the

identified cultural resources in the project area and recommendations for mitigation of

these effects can be proposed.

No substantive responses were received from the contacted organizations. Therefore,

no interviews were conducted for use of the O.S-MG tank project site, as there were no

interviewees identified.

Based on historical research and no response from the above listed contacts, it does not

appear that the project area has been used for traditional cultural purposes within recent

times. Thus, it is reasonable to conclude that pursuant to Act 50, the exercise of native

Hawaiian rights, or any ethnic group, related to gathering, access or other customary

activities will not be affected by the construction of the Kapilimao O.S-millon gallon

storage tank project. Hawaiian rights related to gathering, access or other customary

activities within the project area will not be affected and there will be no direct adverse

effect upon cultural practices or beliefs. See Appendix D.

Based on the lack of traditional cultural practices and the absence of historic features or

artifacts, there were no cultural activities identified within the project area, and as such,

there are no adverse effects from the O.S-MG tank project.

3.11 Infrastructure

3.11.1 Water

The 0.5-MG tank will not create a need for potable water at the project site. Thus,

construction of the O.5-MG tank project will not have an adverse impact on the County's

water system, including sources of water.

3.11.2 Sewer

The 0.5-MG tank project will not require County of Kauai wastewater collection,

treatment, or effluent disposal services. Thus, construction of the 0.5-MG tank project

will not have an adverse effect on the County's wastewater system nor create adverse

effects from the on-site disposal of wastewater.

3.11.3 Electrical

The Kapilimao 0.5-MG tank will be a new facility for the DOW system. As such, there

will be an increase in electrical power usage to supply water to the tank. As part of the

Pre-Assessment process, on May 23, 2007, KIUC stated that they had no objections to

the 0.5-MG tank.

3.12 Visual Considerations

The 0.5-MG tank will be about 20 feet high and 72 feet in diameter. Based on existing

topographic conditions, the top of the tank will be at about elevation 200 feet mean sea

level (msl). The USGS topographic map shows the residential area of Kekaha lies at an

elevation of about 10 feet msl. The topographic map also shows the southern end of

Kapilimao Valley to have a relatively narrow opening which would limit views of the 0.5-

MG tank to short spans along Kaumualii Highway and a relatively small number of

residential units at the western edge of Waimea. The existing vegetation and terrain

would obscure views of the 0.5-MG tank and emergency generator project sites from the

Highway which would limit adverse impacts to views for travelers and residents.

3-11


In addition, the O.5-MG tank will be of medium to dark toned earth or natural colors

which will visually blend with the surrounding environment to further minimize its

potential visual impact.

3.13 Socioeconomic Considerations

As discussed in Chapter 2.13, the comparison between the combined Kekaha and

Waimea Census Designated Place (COP) and the County shows the population of the

combined Kekaha and Waimea is a relatively small portion of the County's total

population. Also, the percentage of white population is about half the percentage of the

County. The median family income in the two COPs is about 7% percent lower when

compared to same County figure. However, the education level in terms of percent high

school graduate or equivalent is higher in Waimea/Kekaha than in the County. Thus,

based on these data, the O.5-MG tank and emergency generator building project would

not result in a disproportionately high adverse human health or environmental effect on

minority and low income populations.

4. RELATIONSHIP to PLANS, POLICIES and CONTROLS

4.1 Hawaii State Plan

The Hawaii State Plan, adopted in 1978 and revised in 1988, now set forth as Chapter

226, Hawaii Revised Statutes, Hawaii State Planning Act, states, among a number of

purposes, that the plan shall serve as a guide for the future long-range development of

the State; shall identify the goals, objectives, policies, and priorities for the State; and

shall provide a basis for determining priorities and allocating limited resources. The 0.5-

MG tank project supports and is consistent with the following State Plan objectives and

policies:

Section 226-6 Objectives and policies for the economy - in general.

(b) (6) Strive to achieve a level of construction activity responsive to, and

consistent with, state growth objectives.

The 0.5-MG tank and emergency generator building will involve construction of new

facilities near and adjacent to the existing Kapilimao Valley Well facility. The 0.5-MG

tank and emergency generator building will increase the level of construction activity in

the County of Kauai during the period of construction which will enhance the state's

growth objectives.

Section 226-16 Objectives and policies for facility systems - water. (a) Planning

for the State's facility systems with regard to water shall be directed towards

achievement of the objective of the provision of water to adequately accommodate

domestic, agricultural, commercial, industrial, recreational, and other needs within

resource capabilities.

(b) To achieve the facility systems water objective, it shall be the policy of

this State to:

(4) Assist in improving the quality, efficiency, service, and storage

capabilities of water systems for domestic and agricultural use.

4-1


The O.S-MG tank will increase water system storage for the Waimea-Kekaha system

which is part of the DOW system serving the southern portion of Kauai. The additional

storage will be consistent with the objective of providing water to adequately

accommodate domestic, agricultural, commercial, industrial, recreational, and other

needs for this area of Kauai.

The O.S-MG tank project will be consistent with the State policy of improving the storage

capabilities of the DOW water system for domestic and agricultural use.

The emergency generator building will provide standby emergency power for the

existing Kapilimao Valley Well facility when commercial power is interrupted or not

available. Thus, the emergency generator building will be consistent with the State

policy of improving service for the DOW water system.

Section 226-11 Objectives and policies for the physical environment - land

based. shoreline. and marine resources.

(b) (3) Take into account the physical attributes of areas when planning and

designing activities and facilities.

The O.S-MG tank emergency generator building have been designed to account for the

existing topographic conditions on the project sites to minimize disturbance to the

surrounding area. The site plan shows the tank pad will be graded to match the

surrounding grade.

4.2 Land Use Plans and Policies

4.2.1 State Land Use District

The Hawaii Land Use Law of Chapter 20S, Hawaii Revised Statutes (HRS), classifies all

land in the State into four land use districts: Urban, Agriculture, Conservation, and Rural.

The O.S-MG tank project site is located in the Agricultural District.

The O.S-MG tank emergency generator building project sites are public facilities to be

used by public agencies for public purposes. Chapter 20S-4.S, HRS, identifies

permissible uses within the Agricultural District to include the following:

4-2

I I I I I' I I I I I I I I I I I I I I

I I I I I I I I 'I I "

I I I I I I I I

Kapilimao O.S-Million Gallon Storage Tank Environmental Assessment Kekaha, Waimea, Kauai, Hawaii

Public, private, and quasi-public utility lines and roadways, transformer

stations, communications equipment buildings, solid waste transfer

stations, major water storage tanks, and appurtenant small buildings such

as booster pumping stations, but not including offices or yards for

equipment, material, vehicle storage, repair or maintenance, or treatment

plants, or corporation yards, or other like structures.

Thus, the 0.5-MG tank and emergency generator building will be consistent with the

Agricultural District classification of the project sites and with the identified permissible

uses set forth in Chapter 205-4.5, HRS.

4.2.2 County of Kauai General Plan

The County of Kauai General Plan is a policy document that sets forth in graphic and

textual form policies to govern the future physical development of the county. The

General Plan serves as a guide to all future County Council actions concerning land use

and development regulations. The current General Plan was adopted as Ordinance No.

753 by the Kauai County Council on November 29, 2000 and signed by the Mayor on

November 30, 2000.

The General Plan states the County's 20-year vision for Kauai and sets forth policies for

achieving that vision. The General Plan includes a chapter entitled "Building Public

Facilities and Services" which includes a section on Water Supply.

The Water Supply policies of the General Plan are set forth below.

(a) Develop a long-range plan to guide expansion, improvement, and

rehabilitation of the County water systems.

(b) Coordinate planning of future water system development and rate

structures with General Plan policies and guidelines.

(c) Support compact development by giving priority to water supply

improvements for existing and planned Urban Center, Residential and

Community, and Resort areas, while also supporting development in

already established Agricultural Communities.

4-3


The 0.5-MG tank project will involve construction of a facility to increase water storage

capacity for the Waimea-Kekaha area of Kauai. DOW facilities are needed to serve the

projected increase in population in the Waimea and Kekaha areas as shown in the 2000

General Plan and the DOW Water Plan 2020. Thus, the 0.5-MG tank project will be

consistent with the Water Supply policies of the General Plan.

The emergency generator building will house a trailer mounted generator which will

provide power to the existing pump and well system in the event of an outage in the

commercial power system. The emergency generator will also be consistent with the

Water Supply policies of the General Plan.

4.2.3 County of Kauai Zoning

The County of Kauai zoning designation for the 0.5-MG tank project site is Open. The

County of Kauai Code, Chapter 8, Comprehensive Zoning Ordinance, Section 8.3.3 sets

forth the uses and structures for which a Use Permit is required. The 0.5-MG tank and

emergency generator building would be classified as a utility installation. Thus, a Use

Permit and Class IV Zoning Permit approved by the County of Kauai Planning

Commission would be required for the 0.5-MG tank and emergency generator building.

The Use Permit is needed so the DOW can provide storage capacity for the projected

water needs of the Kekaha-Waimea water service area. Similarly, the Use Permit is

needed so the DOW can provide a source of power for the existing Kapilimao Well

during periods when service is not available from the commercial system.

4.2.4 County of Kauai Special Management Area

The Coastal Zone Management Act contains the general objectives and policies upon

which all counties within the State have structured specific legislation which created

Special Management Areas (SMA). Any development within the Special Management

Area boundary requires a SMA Use permit which is administered by the County of

Kauai.

The 0.5-MG tank and emergency generator project sites are not located within the

County's SMA.

4.3 COMPLIANCE WITH the STATE OF HAWAII'S DRINKING WATER STATE REVOLVING FUND (DWSRF) PROGRAM REQUIREMENTS

This project may be funded by Federal funds through the State of Hawaii's Drinking

Water State Revolving Fund (DWSRF) program. In 1996, the U.S. Congress amended

the Safe Water Drinking Act (Public Law 104-182; 42 USC 300-j) to establish the

DWSRF which helped each state to set up a special fund to assist public water systems

in financing the cost of improvements. The DWSRF gave special consideration to the

needs of small water systems, such as the DOW system which includes the Kapilimao

Tank. The proposed project is consistent with the program's emphasis on improving

small water systems. This document includes all of the environmental information

required for compliance with the DWSRF program.

4.3.1 CROSS-CUTTING FEDERAL AUTHORITIES

This following sub-sections address the proposed project's relationship to other Federal

"cross-cutting" authorities.

4.3.2 ARCHAEOLOGICAL and HISTORIC PRESERVATION ACT of 1974 (16 U.S.C. Section 461)

16 USC 461. Declaration of national policy, states, "It is declared that it is a national

policy to preserve for public use historic sites, buildings, and objects of national

significance for the inspiration and benefit of the people of the United States. "

As discussed in Chapter 2.9, archival research indicates the O.S-MG tank and

emergency generator project sites are located within lands which, starting from the

1870's through the early 1900s and later, during the middle of the 20th century, were

used for cattle ranching and sugarcane cultivation. These activities no longer occur

within the 0.5-MG tank and emergency generator project sites and surrounding lands.

The previous agricultural uses have displaced former uses such that there are no known

archaeological or historic features at the O.S-MG tank and emergency generator project

sites. The DOW has consulted with the State of Hawaii Historic Preservation Division

(SHPD) of the Department of Land and Natural Resources. SHPD concurred that "no

historic properties will be affected" by the proposed project. See Chapter 3.9, Appendix

4-S


B and Appendix C. SHPD and the Office of Hawaiian Affairs will be provided copies of

the Draft EA to ensure compliance with these statutes.

4.3.3 CLEAN AIR ACT (42 U.S.C. § 7506 (e»

During the late 1940s serious smog incidents in Los Angeles and Donora, Pennsylvania

raised public awareness and concern about this issue once again. In 1955, the

government decided that this problem needed to be dealt with on a national level. The

Air Pollution Control Act of 1955 was the first in a series of clean air and air quality

control acts which are still in effect and continue to be revised and amended.

Among the purposes of the Clean Air Act was (1) to protect and enhance the quality of

the Nation's air resources so as to promote the public health and welfare and the

productive capacity of its population; (2) to initiate and accelerate a national research

and development program to achieve the prevention and control of air pollution; (3) to

provide technical and financial assistance to State and local governments in connection

with the development and execution of their air pollution prevention and control

programs; and (4) to encourage and assist the development and operation of regional

air pollution prevention and control programs.

As discussed in Chapter 2.7, air quality in the southern portion of Kauai is characterized

by low levels of pollutants. The exception would be seasonal dust created during

agricultural planting and harvesting. During these periods, dust would be the primary

source of air pollution. There are no stationary sources of air pollutants, and vehicle

traffic, the main mobile source, is relatively light in the vicinity of the project site.

Grading and excavation will be required for the project to construct a pad for the 0.5-MG

tank and the emergency generator building. Construction activities must comply with

the Department of Health Air Pollution Control rules with respect to fugitive dust during

construction of the 0.5-MG tank and the emergency generator building.

Emissions from the construction vehicles will slightly degrade air quality for the short

period of time they are in operation. However, all applicable emission and ambient air

quality standards will continue to be met. Consequently, no adverse health effects from

this source are anticipated.

4-6

I I I I I I I· I I I I I I I I I I I I

I I I I I I I I I I I I I I I I f I I


Once construction has been completed, operation of the 0.5-MG tank and the

emergency generator building will involve visits approximately 3 times a week by

Department of Water personnel who will perform periodic maintenance and testing of

equipment and systems. This level of activity will not generate sufficient traffic to

adversely affect air quality in the area.

The electrical power consumed in the operation of the 0.5-MG tank will not require

additional power generation as compared to the existing well facilities. Thus, additional

fuel consumption and gaseous emissions from the power generation will represent a

small portion of total power use on Kauai.

4.3.4 COASTAL BARRIER RESOURCES ACT, (16 USC 1451)

In 1982, the US Congress passed the Coastal Barrier Resources Act (CBRA) (16 USC

3501) which established the John H. Chafee Coastal Barrier Resources System

(CBRS), comprised of undeveloped coastal barriers along the Atlantic, Gulf, and Great

Lakes coasts. The law encourages the conservation of hurricane prone, biologically rich

coastal barriers by restricting Federal expenditures that encourage development, such

as Federal flood insurance through the National Flood Insurance Program

The Coastal Barrier Resources Reauthorization Act of 2000 reauthorized the Coastal

Barrier Resources Act (CBRA) and directed the U.S. Fish and Wildlife Service to

complete a Digital Mapping Pilot Project that includes digitally produced draft maps for

up to 75 John H. Chafee Coastal Barrier Resources System (CBRS) areas and a report

to Congress that describes the feasibility and costs for completing digital maps for all

CBRS areas.

The purpose of the CBRA is to minimize the loss of human life, wasteful expenditure of

Federal revenues, and the damage to fish, wildlife, and other natural resources

associated with the coastal barriers along the Atlantic and Gulf coasts and along the

Great Lakes by restricting future Federal expenditures and financial assistance which

have the effect of encouraging development along coastal barriers.

The 0.5-MG tank and the emergency generator building project sites are located about

1.25 miles inland from the shoreline on the southern coast of Kauai. Thus, the 0.5-MG

4-7


tank and the emergency generator building project will not involve construction of

facilities along coastal barriers.

4.3.5 COASTAL ZONE MANAGEMENT ACT (16 U.S.C. § 1456(C)(1»

In 1972, the US Congress enacted the Federal Coastal Zone Management Act to

ensure that each Federal agency undertaking an activity within or outside the coastal

zone that affects any land or water use or natural resource of the coastal zone shall be

carried out in a manner which is consistent to the maximum extent practicable with the

enforceable policies of approved State management programs. Each Federal agency

carrying out an activity subject to the Act shall provide a consistency determination to

the relevant State agency designated under section 1455(d)(6) of this title at the earliest

practicable time.

In 1977, Hawaii enacted Chapter 205A, HRS, the Hawaii Coastal Zone Management

(CZM) Program. The CZM area encompasses the entire state, including all marine

waters seaward to the extent of the state's police power and management authority,

including the 12-mile U.S. territorial sea and all archipelagic waters.

The Hawaii Coastal Zone Management Program focuses on ten policy objectives:

• Recreational Resources. To provide coastal recreational opportunities

accessible to the public and protect coastal resources uniquely suited for

recreational activities that cannot be provided elsewhere.

• Historic Resources. To protect, preserve, and where desirable, restore those

natural and manmade historic and prehistoric resources in the coastal zone

management area that are significant in Hawaiian and American history and

culture.

• Scenic and Open Space Resources. To protect, preserve, and where desirable,

restore or improve the quality of coastal scenic and open space resources.

• Coastal Ecosystems. To protect valuable coastal ecosystems, including reefs,

from disruption and to minimize adverse impacts on all coastal ecosystems.

4-8

I I I I I I I I I I I I I I ,I I I I I

I I I I I I I I I ,I J I I I I I , I I


• Economic Uses. To provide public or private facilities and improvements

important to the State's economy in suitable locations; and ensure that coastal

dependent development such as harbors and ports, energy facilities, and visitor

facilities are located, designed, and constructed to minimize adverse impacts in

the coastal zone area.

• Coastal Hazards. To reduce hazard to life and property from tsunami, storm

waves, stream flooding, erosion, subsidence, and pollution.

• Managing Development. To improve the development review process,

communication, and public participation in the management of coastal resources

and hazards.

• Public Participation. To stimulate public awareness, education, and partiCipation

in coastal management; and maintain a public advisory body to identify coastal

management problems and provide policy advice and assistance to the CZM

program.

• Beach Protection. To protect beaches for public use and recreation; and locate

new structures inland from the shoreline setback to conserve open space and to

minimize loss of improvements due to erosion.

• Marine Resources. To implement the State's ocean resources management

plan.

Other key areas of the CZM program include: a permit system to control development

within a Special Management Area (SMA) managed by each County and the Office of

Planning; a Shoreline Setback Area which serves as a buffer against coastal hazards

and erosion, and protects view-planes; and marine and coastal resources. Finally, a

Federal Consistency provision requires that Federal activities, permits and financial

assistance be consistent with the Hawaii CZM program.

The O.5-MG tank and the emergency generator building project sites are located about

1.25 miles from the coastline and not within the County of Kauai SMA. The O.5-MG tank

and the emergency generator building project does not involve the placement, erection,

or removal of materials near the coastline. Activities at the O.5-MG tank and the

4-9


emergency generator building project sites do not have the potential to significantly

affect coastal resources. Finally, it is consistent with the CZM objectives that are

relevant to this type of project.

A copy of this Draft EA is being sent to the Office of Planning, attached to the State of

Hawaii Department of Business, Economic Development, and Tourism. The

Department's response is expected to confirm the consistency of the project with the

CZM Act.

4.3.6 ENDANGERED SPECIES ACT (16 U.S.C. 1S36(A)(2) and (4»

The Endangered Species Act (16 U.S.C. Section 1531-1544, as amended) provides

broad protection for species of fish, wildlife, and plants that are listed as threatened or

endangered in the U.S. or elsewhere. The Act mandates that Federal agencies seek to

conserve endangered and threatened species and use their authorities in furtherance of

the Act's purposes. Provisions are made for listing species, as well as for recovery

plans and the deSignation of critical habitat for listed species.

16 USC Section 1536, Interagency Cooperation, states each Federal agency shall, in

consultation with and with the assistance of the Secretary, insure that any action

authorized, funded, or carried out by such agency (an "agency action") is not likely to

jeopardize the continued existence of any endangered species or threatened species or

result in the destruction or adverse modification of habitat of such species which is

determined by the Secretary, after consultation as appropriate with affected States, to

be critical, unless such agency has been granted an exemption for such action.

As discussed in Chapter 2.5, the 0.5-MG tank and the emergency generator building

project sites do not contain US Fish and Wildlife Service or Department of Land and

Natural Resources listed or proposed threatened or endangered species of flora or

fauna.

Copies of the Draft EA will be provided to the U.S. Fish and Wildlife Service and to the

State Department of Land and Natural Resources (DLNR) for review and comment.

4.3.7 ENVIRONMENTAL JUSTICE, EXECUTIVE ORDER 12898

Executive Order 12898, Environmental Justice, was signed on February 11, 1994. The

intent of Executive Order 12898 (full title Federal Actions to Address Environmental

Justice to Minority and Low Income Populations) is to avoid disproportionately high

adverse human health or environmental effects of projects on minority and low income

populations. Executive Order 12898 also requires Federal agencies ensure that

minority and low income communities have adequate access to public information

related to health and the environment.

As discussed in Chapter 2.13, the comparison between the combined Kekaha and

Waimea Census Designated Place (COP) and the County shows the population of the

combined Kekaha and Waimea is a relatively small portion of the County's total

population. Also, the percentage of white population is about half the percentage of the

County. The median family income in the two COPs is about 7% percent lower when

compared to same County figure. However, the education level in terms of percent high

school graduate or equivalent is higher in Waimea/Kekaha than in the County. Thus,

based on these measurements, the 0.5-MG tank and emergency generator building

project would not result in a disproportionately high adverse human health or

environmental effect on minority and low income populations.

4.3.8 FLOODPLAIN MANAGEMENT, EXECUTIVE ORDER 11988 as

AMENDED by EXECUTIVE ORDER 12148

Executive Order 11988, Floodplain Management, dated May 24, 1977 requires Federal

agencies to take action to reduce the risk of flood loss, restore the natural and beneficial

values of floodplains, and minimize the impacts of floods on human safety, health, and

welfare. Executive Order 12148, July 20, 1979, amended Executive Order 11988. The

main feature of the amendment added that agencies with responsibilities for Federal

real estate properties and facilities shall, at a minimum, require the construction of

Federal structures and facilities to be in accordance with the criteria of the National

Flood Insurance Program.

As discussed in Chapter 2.2, the Kapilimao Tank project site is located in Zone X on the


1500020035E, Map Revised September 16, 2005. Zone X is defined as: "area

4-11


determined to be outside of the 0.2% annual chance floodplain." This would indicate the

project site is not located within the flood hazard area of a SOD-year flood plain. Thus,

the project site is not subject to flooding and would be consistent with applicable

regulations and guidance relating to floodplain management.

4.3.9 PROTECTION of WETLANDS EXECUTIVE ORDER 11990,1977

Executive Order 11990, Protection of Wetlands, dated 1977 requires Federal agencies

to avoid, preserve, or mitigate effects of new construction projects on lands which have

been designated wetlands.

As discussed in Chapter 2.2, there are no surface water resources on the O.S-tank and

emergency generator building project sites. Further, no conditions were observed which

would classify the project sites as a wetlands.

Copies of the Draft EA will be sent to the administrator of the Pacific Island Eco-Region,

U.S. Fish and Wildlife Service, and to the State Department of Land and Natural

Resources Department of Aquatic Resources to ensure adequate consideration of this

topic in the environmental review for this project.

4.3.10 FARMLAND PROTECTION POLICY ACT (7 U.S.C. § 4202(8»

The U.S. Congress adopted the Farmland Protection Policy Act (FPPA) (Public Law 97-

98) on December 22, 1981. The u.s. Department of Agriculture (USDA), Natural

Resources Conservation Service (NRCS) has national leadership for administering the

FPPA. The effective date of the FPPA rule (part 658 of Title 7 of the Code of Federal

Regulations) is August 6, 1984.

The stated purposes of the FPPA are to:

• Minimize the extent to which Federal programs contribute to the unnecessary

and irreversible conversion of farmland to nonagricultural uses.

• Assure that Federal programs are administered in a manner that, to the extent

practicable, will be compatible with State, unit of local government, and private

programs and policies to protect farmland.

"Farmland", as used in the FPPA, includes prime farmland, unique farmland, and land of

statewide or local importance. "Farmland" subject to FPPA requirements does not have

to be currently used for cropland.

As discussed in Chapter 2.3, the 0.5-MG tank and emergency generator project sites

are not classified in the Department of Agriculture "Agricultural Lands of Importance to

the State of Hawaii" (ALlSH) map, indicating that the lands are not the highest

classification for productivity and high yield. Most of the nearby surrounding lands are

not classified in the ALISH maps. Consequently, the 0.5-MG tank and emergency

generator project is in substantial compliance with the FPPA.

4.3.11 FISH and WILDLIFE COORDINATION ACT (16 U.S.C. § 661-666)

The Fish and Wildlife Coordination Act, as amended, authorizes the Secretaries of

Agriculture and Commerce to require consultation with the Fish and Wildlife Service and

the fish and wildlife agencies of States where the "waters of any stream or other body of

water are proposed or authorized, permitted or licensed to be impounded, diverted ... or

otherwise controlled or modified" by any agency under a Federal permit or license.

Consultation is to be undertaken for the purpose of "preventing loss of and damage to

wildlife resources."

As documented in Chapter 2.2, the 0.5-MG tank and emergency generator building

project sites do not contain surface water resources. Thus, construction of the 0.5-MG

tank and emergency generator building will not result in a diversion of any water body

and will not result in impacts on fish or wildlife resources.

The U.S. Fish and Wildlife Service and the State Department of Land and Natural

Resources will be asked to comment on the Draft EA.

4.3.12 NATIONAL HISTORIC PRESERVATION ACT of 1966

(16 U.S.C. § 470 (f»

Section 106 of the National Historic Preservation Act of 1966 (PL 89-665, codified as 16

USC 470f) requires that Federal agencies consider the effects of their projects on

historic properties and allow the Advisory Council on Historic Preservation a reasonable

opportunity to comment on such projects. The Section 106 review regulations are set

4-13


forth in CFR 800. In most cases, the State of Hawaii Department of Land and Natural

Resources Historic Preservation Division acts for the Advisory Council to undertake this

review process. The Historic Preservation Division must concur that the proposed

project will have "no effect" on historic properties.

As discussed in Chapter 2.9, archival research indicates the 0.5-MG tank and

emergency generator project sites are located within lands which, starting from the

1870's through the early 1900s and later, during the middle of the 20th century, were

used for cattle ranching and sugarcane cultivation. These activities no longer occur

within the 0.5-MG tank and emergency generator project sites and surrounding lands.

The previous agricultural uses have displaced former uses such that there are no known

archaeological or historic features at the 0.5-MG tank and emergency generator project

sites. The DOW has consulted with the State of Hawaii Historic Preservation Division

(SHPD) of the Department of Land and Natural Resources. SHPD concurred that "no

historic properties will be affected" by the proposed project. See Chapter 3.9, Appendix

B and Appendix C. SHPD and the Office of Hawaiian Affairs will be provided copies of

the Draft EA to ensure compliance with these statutes.

4.3.13 SAFE DRINKING WATER ACT (42 U.S.C. Chapter 6A, Public Health Service, Subchapter XII, Safety of Public Water Systems, 300f.)

The Safe Drinking Water Act (SDWA) was originally passed by Congress in 1974 to

protect public health by regulating the nation's public drinking water supply. The law

was amended in 1986 and 1996 and requires many actions to protect drinking water

and its sources; rivers, lakes, reservoirs, springs, and ground water wells. (SDWA does

not regulate private wells which serve fewer than 25 individuals.) SDWA authorizes the

United States Environmental Protection Agency (US EPA) to set national health-based

standards for drinking water to protect against both naturally-occurring and man-made

contaminants that may be found in drinking water. US EPA, state governments, and

municipal water systems then work together to make sure that these standards are met.

Originally, SDWA focused primarily on treatment as the means of providing safe

drinking water at the tap. The 1996 amendments greatly enhanced the existing law by

recognizing source water protection, operator training, funding for water system

4-14




improvements, and public information as important components of safe drinking water.

This approach ensures the quality of drinking water by protecting it from source to tap.

The Safe Drinking Water Act requires that all public water systems meet stringent water

quality standards. These standards cover a long list of potential chemical, radiological

and biological contaminants. The standards distinguish between surface water and

groundwater sources, with the testing and monitoring requirements for surface water

and GWUDI sources being far greater than those for groundwater sources.

The primary purpose of the 0.5-MG tank project is to provide the water storage needed

for the Waimea-Kekaha water system as shown by Water Plan 2020. The storage

needs set forth for the system in Water Plan 2020 show the need for an additional

600,000 gallons of storage in 2000 and another 500,000 gallons of storage by 2020.

The Kapilimao tank is needed to fulfill the long-term projected storage needs for the

Waimea-Kekaha water system.

Since the existing Kapilimao Valley Well facility does not include an emergency

generator, there is a need for an emergency generator at the Well site. The emergency

generator would be a portable trailer-mounted unit and would provide power to the Well

should there be an outage in the commercial power system.

These improvements would increase the storage capability and reliability of the DOW

system and improve the DOW's ability to meet the needs of its customers. Thus, the

improvements would be consistent with the objective of the SWDA to provide safe

drinking water to the residents of the Waimea-Kekaha area of Kauai.

4.3.14 WILD and SCENIC RIVERS ACT (16 U.S.C. 1271-1287)

The Wild and Scenic Rivers Act was first passed in October 1968 and has been

amended a number of times. (16 U.S.C. §§ 1271-1287, October 2, 1968, as amended

1972, 1974-1976, 1978-1980, 1984, 1986-1994 and 1996.)

This Act established a National Wild and Scenic Rivers System for the protection of

rivers with important scenic, recreational, fish and wildlife, and other values. Rivers are

classified as wild, scenic or recreational. The Act also designated specific rivers for

inclusion in the System and prescribes the methods and standards by which additional

rivers may be added. The Act contains procedures and limitations for control of lands in

4-15



federally administered components of the System and for disposition of lands and

minerals under Federal ownership. Hunting and fishing are permitted in components of

the System under applicable federal and state laws.

The purpose of this act, as stated in Section (b) of its preamble is as follows:

It is hereby declared to be the policy of the United States that certain

selected rivers of the Nation which, with their immediate environments,

possess outstandingly remarkable scenic, recreational, geologic, fish and

wildlife, historic, cultural, or other similar values, shall be preserved in

free-flowing condition, and that they and their immediate environments

shall be protected for the benefit and enjoyment of present and future

generations. The Congress declares that the established national policy

of dam and other construction at appropriate sections of the rivers of the

United States needs to be complemented by a policy that would preserve

other selected rivers or sections thereof in their free-flowing condition to

protect the water quality of such rivers and to fulfill other vital national

conservation purposes.

There are no rivers in Hawaii designated as wild and scenic as part of the Wild and

Scenic Rivers Act.

As discussed Chapter 2.2, there are no surface water resources on the O.5-MG tank and

emergency generator building project sites. There is an unnamed intermittent stream

located east of the O.5-MG tank and emergency generator building project sites.

Development of the project sites does not have the potential to affect the hydrology,

water quality, or aquatic resources in the unnamed intermittent stream. Thus, project is

consistent with the provisions of the Wild and Scenic Rivers Act.

4.3.15 FISHERY CONSERVATION AND MANAGEMENT, Magnuson-Stevens Fishery Conservation and Management Act (16 USC Sec. 1801)

The Congress found and declared the following:

(1) The fish off the coasts of the United States, the highly migratory

species of the high seas, the species which dwell on or in the Continental

4-16




Shelf appertaining to the United States, and the anadromous species

which spawn in United States rivers or estuaries, constitute valuable and

renewable natural resources. (2) Certain stocks of fish have declined to

the point where their survival is threatened, and other stocks of fish have

been so substantially reduced in number that they could become similarly

threatened (3) Commercial and recreational fishing constitutes a major

source of employment and contributes significantly to the economy of the

Nation. (4) International fishery agreements have not been effective in

preventing or terminating the overfishing of these valuable fishery

resources. (5) Fishery resources are finite but renewable. If placed

under sound management before overfishing has caused irreversible

effects, the fisheries can be conserved and maintained so as to provide

optimum yields on a continuing basis. (6) A national program for the

conservation and management of the fishery resources of the United

States is necessary to prevent overfishing, to rebuild overfished stocks, to

insure conservation, to facilitate long-term protection of essential fish

habitats, and to realize the full potential of the Nation's fishery resources.

(7) A national program for the development of fisheries which are

underutilized or not utilized by the United States fishing industry, including

bottom fish off Alaska, is necessary to assure that our citizens benefit

from the employment, food supply, and revenue which could be

generated thereby. (8) The collection of reliable data is essential to the

effective conservation, management, and scientific understanding of the

fishery resources of the United States. (9) One of the greatest long-term

threats to the viability of commercial and recreational fisheries is the

continuing loss of marine, estuarine, and other aquatic habitats. (10)

Pacific Insular Areas contain unique historical, cultural, legal, political,

and geographical circumstances which make fisheries resources

important in sustaining their economic growth.

The O.5-MG tank and emergency generator building project sites do not include water

resources which supports fishery resources. Thus, the O.5-MG tank and emergency

generator building project will not have an adverse effect on fishery resources.

Kapi/imao O.5-Million Gallon Storage Tank Environmental Assessment Kekaha, Waimea, Kauai, Hawaii

5. ALTERNATIVES to the PROPOSED ACTION

5.1 No Action Alternative

The No Action alternative would not construct the 0.5-MG tank and the emergency

generator building adjacent to the existing Kapilimao Valley Well facility. Although there

would be no disturbance to the project sites, the O.5-MG tank is needed to provide

water storage to meet the projected demands of the Waimea-Kekaha water system.

The projected population growth for Waimea-Kekaha area is about 16.0% to 2020. In

addition to potable water needs, the 0.5-MG tank is necessary to meet the fire protection

requirements of the area.

The existing Kapilimao Valley Well facility does not include an emergency generator to

provide electrical power in the event of an outage to the commercial system serving the

facility. The lack of emergency power would limit the DOW ability to supply water to the

Waimea-Kekaha system during the period of the outage. Based on these

considerations, the No Action alternative is not considered a feasible alternative.

5.2 Other Sites

Use of other sites was considered for the proposed 0.5-MG tank. However, the

proposed project's location and siting considerations, including feasible alternatives,

stem from the basic design of the Waimea-Kekaha water system which has other

storage tanks sited at the same floor elevation (178 feet mean seal level) and spillway

elevation (198 feet msl) as the proposed 0.5 MG storage tank. This elevation is critical

to maintain water pressure in the system.

Therefore, to meet the DOW system requirements for a tank floor elevation of 178 feet

msl and to be close to the existing Kapilimao Valley Well, potential water tank sites were

also in the same general area as the selected site. One of the alternate sites would

have required construction of a cast-in-place concrete retaining wall to provide a level

pad for the tank. The other site considered would have placed the tank above an

existing vertical rock outcrop directly west of the Well site. Construction of a retaining

wall would have used more concrete to construct than would be needed for the selected

site plan. The retaining wall would also require more time to construct the 0.5-MG tank.

Use of the site above the rock outcrop was not considered desirable as there was

5-1


concern for the long-term stability of outcrop and its ability to bear the weight of the tank.

Based on these considerations, use of other sites was not considered a feasible

alternative.

5-2




6. DETERMINATION

Short-term construction impacts include disruption to the project site and surrounding

areas during construction, decline in air quality from construction activities, and an

increase in noise levels. Once construction has been completed, the short-term

adverse impacts will no longer occur.

Based on analysis of the anticipated impacts, a Finding of No Significant Impact

(FONSI) is determined for the O.S-MG tank project. The significance criteria to make

this determination are set forth below and in Hawaii Administrative Rules Title 11, State

of Hawaii Department of Health, Chapter 200, Environmental Impact Statement Rules.

1) Involve an irrevocable commitment to loss or destruction of any natural or cultural resources;

The O.S-MG tank project site does not provide habitat for Federal or State of Hawaii

listed or candidate threatened or endangered species of flora or fauna. Thus,

construction at the O.S-MG tank project will not result in the loss or destruction of natural

resources.

Based on the results of the archaeological field investigation, construction of the O.S-MG

tank should have no adverse impacts to historic sites. The State of Hawaii Department

of Land and Natural Resources Historic Preservation Division (SHPD) has concurred

that "no historic properties will be affected" by construction of the O.S-MG tank project.

See Appendix E.

Based on the 1998 archaeological investigation of the Well site which included the

emergency generator building site, on November 23, 1999, the Historic Preservation

Division issued a determination letter that the Well project would have "no effect" on

significant historic sites. See Appendix C.

2) Curtail the range of beneficial uses of the environment,

The O.S-MG tank project site will use lands that are currently undeveloped and vacant of

any uses. The O.S-MG tank will occupy an area of approximately 0.6 acres and the

emergency generator about 1,060-square feet of expansion to the existing Well site.

6-1


These additional areas are a minor portion of the undeveloped land in the southern

portion of Kauai. Thus, the 0.5-MG tank and the emergency generator project will not

curtail the beneficial uses of the environment.

3) Conflict with the State's long-term environmental policies or goals as

expressed in Chapter 344, HRS, and any revisions thereof and

amendments thereto, court decisions, or executive orders;

The 0.5-MG tank and emergency generator project will not involve actions or activities

that would adversely affect the natural resources on their project sites. The 0.5-MG

tank and emergency generator project will be consistent with the guidelines of Chapter

344, HRS, as the project will provide a public facility to support the critical function of

supplying potable water to the southern area of the County of Kauai. As such, the 0.5-

MG tank and emergency generator project will not conflict with the State's long-term

environmental policies or goals as expressed in Chapter 344, HRS.

4) Substantially affect the economic or social welfare of the community or state;

The 0.5-MG tank and emergency generator will be public facilities to be used for public

purposes. The 0.5-MG tank and emergency generator are an integral part of the

infrastructure needed to maintain the health and welfare of the community. The 0.5-MG

tank and emergency generator project will not have an adverse effect on the economic

or social welfare of the community.

5) Substantially affect public health;

An efficient and adequate potable water system is needed to protect the public health of

the residents and visitors of the County of Kauai. The 0.5-MG tank and emergency

generator project will serve as the facility for the DOW to conduct its mandated public

functions. Thus, the 0.5-MG tank and emergency generator project will not have an

adverse effect on public health.

6-2




6) Involve substantial secondary impacts, such as population changes or

effects on public facilities;

The 0.5-MG tank and emergency generator project will be a public facility which will be

used by the County of Kauai DOW to support its assigned mission. No DOW or

contractor personnel will be assigned to daily operation of the 0.5-MG-tank or

emergency generator. DOW personnel will visit the project site to conduct tests and to

perform maintenance service. The personnel are expected to be residents of the

County of Kauai. Thus, construction of the 0.5-MG tank and emergency generator will

not create secondary impacts, such as population changes or effects on public facilities.

7) Involve a substantial degradation of environmental quality;

The 0.5-MG tank and emergency generator project is anticipated to result in short-term

impacts to noise, air quality and traffic in the immediate vicinity of the project site during

the period of construction. The 0.5-MG tank and emergency generator sites do not

contain Federal or State listed or candidate threatened or endangered species of flora or

fauna.

Further, based on the results of the archaeological field surveys, construction of the 0.5-

MG tank and emergency generator project should have no adverse impact to historic

sites. The State of Hawaii Department of Land and Natural Resources Historic

Preservation Division (SHPD) has concluded that "no historic properties will be affected"

by construction of the 0.5-MG tank and emergency generator project. See Appendix E.

Based on the above findings, the O.5-MG tank and emergency generator project will not

result in a substantial degradation of environmental quality.

8) Have a cumulative effect upon the environment or involves a commitment

for larger actions;

The 0.5-MG tank and emergency generator project does not involve a commitment to

further actions to other County of Kauai related projects. As a result, the 0.5-MG tank

and emergency generator project will not have a cumulative effect upon the environment

or involve a commitment by the DOW to larger actions in the County of Kauai.

6-3


9) Affect a rare, threatened or endangered species;

The O.S-MG tank and emergency generator project sites do not contain Federal or State

listed or candidate threatened or endangered species of flora or fauna. Thus, the O.S

MG tank and emergency generator project will not affect a threatened or endangered

species.

10) Detrimentally affect air or water quality or ambient noise levels;

Operation of construction equipment will increase noise and exhaust emission levels in

the immediate vicinity of the O.S-MG tank and emergency generator project sites. Once

operational, the O.S-MG tank and emergency generator project will contribute almost no

additional noise or air emissions to the local area.

11) Affects or is likely to suffer damage by being located in an environmentally

sensitive area such as a floodplain, tsunami zone, beach, erosion-prone

area, geologically hazardous land, estuary, fresh water or coastal waters;

The O.S-MG tank and emergency generator project sites are located in Zone X on the


1S000202S2E, Map Revision September 16, 200S. Zone X is defined as: "area

determined to be outside of the 0.2% annual chance floodplain.· This indicates the

project site is not located within the flood hazard area of a SOO-year flood plain. Thus,

the project sites are not subject to flooding.

Similarly, the O.S-MG tank and emergency generator project sites are not located in a

tsunami zone, erosion-prone area, geologically hazardous land, estuary, fresh water or

coastal waters.

12) Substantially affect scenic vistas and view planes identified in county or

state plans or studies;

The O.S-MG tank will be about 20 feet high and 72 feet in diameter. Based on existing

topographic conditions, the top of the tank will be at about elevation 200 feet mean sea

level (msl). The USGS topographic map shows the residential area of Kekaha lies at an

elevation of about 10 feet msl. The topographic map also shows the southern end of

6-4




Kapilimao Valley to have a relatively narrow opening which would limit views of the 0.5-

MG tank to short spans along Kaumualii Highway and a relatively small number of

residences at the eastern edge of Kekaha. The existing vegetation and terrain would

obscure views of the 0.5-MG tank and emergency generator project sites from the

Highway which would limit adverse impacts to views for travelers and residents.

13) Require substantial energy consumption.

The 0.5-MG tank is a public facility to be used for public purposes. It will be planned

and designed to minimize use of electrical power. Thus. the 0.5-MG tank and

emergency generator project will not create a substantial increase in energy

consumption.

Based on these findings and the assessment of potential impacts from the 0.5-MG tank

and emergency generator project. a Finding of No Significant Impact (FONSI) is

determined.

The aforementioned project consists of a water tank project.

We believe that "no historic properties will be affected" by this undertaking because: 181 a) intensive cultivation has altered the land Db) residential development/urbanization has altered the land o c) previous grubbing/grading has altered the land 181 d) an acceptable archaeological assessment or inventory survey found no historic properties o e) this project has gone through the historic review process, and mitigation has been completed I8l f) other: Archaeological Field Inspection o/Three Alternative Locations &lated to the

Kaipil/mao Water Well Project Kekaha Ahupua 'a, Waimea District, KauaIIsland. Hawaii (SCS, Schefcheck and Deg&, 2007)

In the event that historic resources, including human skeletal remains, are identified during the construction activities, all work needs to cease in the immediate vicinity of the find, the find needs to be protected from additional disturbance, and the State Historic Preservation Division, Kauai Section, needs to be contacted immediately at (808) 742-7033.

Dear Mr. Sunada:

Thank you for your May 16. 2007 comment letter (EP0-07--085) regarding the proposed Kapitimao O.S-Million Gallon storage Tank project. The Draft Environmental Assessment (EA) will note a National Pollutant Discharge Elimination Permit System (NPDES) is required prior to construction activities at the project site. A NPDES is also required for discharge of hydro-testing water.

The Draft EA will note the designer or contractor must also submit the NPDES Notice of Intent to the Department of Land and Natural Resources State Historic Preservation Division.

We appreciate your participation in the Environmental Assessment process. If you have any questions. please call me at 808.946.2277 or fax to 808.946.2253.

SUBJECT: DRAFT ENVIRONMENTAL ASSESSMENT, PRE-ASSESSMENT CONSULTATION; KAPILIMAO 0.5 MILLION GALLON STORAGE TANK TMK 1-2-2-01 PW 4.07.236

Dear Mr. Sakaguchi,

We completed our review of the subject draft environmental assessment We offer the following comments:

• Since the grading is within a self contained government controlled area under the Stste ofHawai'i, we can exempt the grading work for the tank site and the driveway access. However, we expect the Stste to monitor the grading activities and insure Best Management Practices (BMP's) are provided at all times to the maximum extent practicable to prevent sedimentation, erosion or dust to streams, natural water courses, and the property of others.

• Although we are exempting the project from requiring a grading permit, the State Historic Preservation Office needs to be consulted.

• Additionally, although not stated, the borrow as well as the disposal sites may require a grading permit that must also fulfill the County's Sediment and Erosion Control Ordinance No. 808. The disposal and borrow sites will need to be identified when a building permit is submitted for our approval for the water tank construction.

• A flood study should be prepared to address the increase in storm runoff due to the change in land use from Agricultural to installation of impervious surfaces such as the proposed 0.5 MG water tank and asphalt pavement. The report needs to address the increase in storm flows as a result of the development and provide mitigating drainage measures to maintsin the pre-existing development conditions. We are concerned with the increased storm flows to Cox Drain at Kekaha Road (TMK 1-3-5 & 6) and ditch at Kikiaola Harbor.

Dear Mr. Fujimoto:

Thank you for your April 30, 2007 comment letter (PW4.07.236) regarding proposed Kapilimao 0.5-Million Gallon Storage Tank project.

The Draft Environmental Assessment will note that:

1) The County will exempt the grading work for the tank site and driveway access. Grading and erosion control plans, including the Best Management Practices (BMPs) that the contractor must use, will be part of the design drawings. The BMPs will Include the use of silt fences and rock filter berms to control runoff and sediment from the project site. Construction inspections will be performed by the Department of Water who will also be monttoring the grading.

2) The Draft EA will include the Archeological Field Inspection report which has been submttled to and accepted by the Department of Land and NatUral Resources Historic Preservation Division.

3) The quantities of cut and/or fill needed for construction of the tank has not yet been determined. Should off-site disposal of material be necessary, the disposal site will be identified by the contractor who will submtt the site to the County for review and approval.

4) Hydrologic and runoff analysis will be prepared as part of the design work. The increase In runoff will be shown In the analysiS. The project site plan in the Draft EA will show a silt fence will be constructed on the downslope side of the

construction area to control storm runoff during the construction period. In addition, the design plans show a permanent detention basin will be used to retain storm runoff from the area of the O.5-MG tank. The detention basin will be constructed from on-site rock material and underlain with a filter fabric which will allow percolation. In addition, the detention basin will retain sediment before flows enter the unnamed drainageway east of the tank site. Use of the detention basin should remove sediment and maintain pre-exlsting flow conditions in the area of the project site.

In addition to the detention basin, the design drawings show the excavation/graded area of the tank project site will Included hydromulchlng to establish vegetation In the disturbed area. This measure will also control sediment runoff Into the adjacent drainageway and to other downstream areas.

We appreciate your participation in the Environmental Assessment process. if you have any questtons, please call me at 808.946.2277 or fax to 808.946.2253.

INTRODUCTION

At the request of Wilson Okamoto Corporation, Scientific Consultant Services, Inc. (SCS) conducted a Cultural Impact Assessment, on a parcel (TMK: 1-2-002:00 I

por.) located in Waimea Ahupua'a, Waimea District, Kaua'i Island (Figure I). At present, the County ofKaua'i Department of Water proposes the construction of a new

Kapilimao-O.S million gallon water storage tank system (Figure 2).

The Constitution of the State of Hawai'i clearly states the duty of the State and its agencies is to preserve, protect, and prevent interference with the traditional and

customary rights of native Hawaiians. Article XII, Section 7 requires the State to

"protect all rights, customarily and traditionally exercised for subsistence, cultural and

religious purposes and possessed by ahupua 'a tenants who are descendants of native

Hawaiians who inhabited the Hawaiian Islands prior to 1778" (2000). In spite of the

establishment of the foreign concept of private ownership and western-style government,

Kamehameha III (Kauikeaouli) preserved the peoples traditional right to subsistence. As

a result in 1850, the Hawaiian Government confirmed the traditional access rights to

native Hawaiian ahupua 'a tenants to gather specific natural resources for customary uses

from undeveloped private property and waterways under the Hawaiian Revised Statutes

(HRS) 7-t. In 1992, the State ofHawai'i Supreme Court, reaffirmed HRS 7-1 and

expanded it to include, "native Hawaiian rights ... may extend beyond the ahupua 'a in

which a native Hawaiian resides where such rights have been customarily and

traditionally exercised in this manner" (Pele Defense Fund v. Paty, 73 Haw.578, 1992).

Act 50, enacted by the Legislature of the State of Hawaii (2000) with House Bill

2895, relating to Environmental Impact Statements, proposes that:

•.. there is a need to clarify that the preparation of environmental assessments or environmental impact statements should identify and address effects on Hawaii's culture, and traditional and customary rights ... [H.B. NO. 2895].

Act 50 requires state agencies and other developers to assess the effects of

proposed land use or shore line developments on the "cultural practices of the community and State" as part of the HRS Chapter 343 environmental review process (2001). Its

- - - .. .. - •• .. .. .. .. - .. - .. -

- - - .. - - - - .. - .. .. - .. - -purpose has broadened, ''to promote and protect cultural beliefs, practices and resources

of native Hawaiians [and] other Ethnic groups, and it also amends the definition of

'significant effect' to be re-defined as "the sum of effects on the quality of the

environment including actions that are •.. contrary to the State's environmental

policies ... or adversely affect the economic welfare, social welfare, or cultural practices

of the community and State" (H.B. 2895, Act SO, 2000).

Thus, Act SO requires an assessment of cultural practices to be included in the

Environmental Assessments and the Environmental Impact Statements, and to be taken into consideration during the planning process. The concept of geographical expansion is

recognized by using, as an example, "the broad geographical area, e.g. district or

ahupua '0" (OEQC (997). It was decided that the process should identify

'anthropological' cultural practices, rather than 'social' cultural practices. For example,

limu (edible seaweed) gathering would be considered an anthropological cultural

practice, while a modem-day marathon would be considered a social cultural practice,

According to the Guidelines for Assessing Cultural Impacts established by the Hawaii State Office of Environmental Quality Control (OEQC 1997):

The types of cultural practices and beliefs subjcct to assessment may include subsistence, commercial, residential, agricultural, access-related, recreational, and religions and spiritual customs. The types of cultural resources subject to assessment may include traditional cultural properties or other types of historic sites, both manmade and natural, which support such cultural beliefs.

This Cultural Impact Assessment involves evaluating the probability of impacts

on identified cultural resources, including values, rights, beliefs, objects, records,

properties, and stories occurring within the project area and its vicinity (H.B. 2895, Act

50,2000).

METHODOLOGY

This Cultural Impact Assessment was prepared in accordance with the methodology and content protocol provided in the Guidelines for Assessing Cultural Impacts (OEQC 1997). In outlining the "Cultural Impact Assessment Methodology", the OEQC stated:

4

-

-

· . .information may be obtained through scoping, community meetings, ethnographic interviews and oral histories ... (1997).

The report contains archival and documentary research, as well as communication

with organizations having knowledge of the project area, its cultural resources, and its

practices and beliefs. This Cultural Impact Assessment was prepared in accordance with

the methodology and content protocol provided in the Guidelines for Assessing Cultural

Impacts (OEQC 1997). The assessment concerning cultural impacts should address, but

not be limited to, the following matters:

(I) a discussion of the methods applied and results of consultation with individuals and organizations identified by the preparer as being familiar with cultural practices and features associated with the project area, including any constraints oflimitations with might have affected the quality ofthe information obtained;

(2) a description of methods adopted by the preparer to identifY, locate, and select the persons interviewed, including a discussion of the level of effort undertaken;

(3) ethnographic and oral history interview procedures, including the circumstances under which the interviews were conducted, and any constraints or limitations which might have affected the quality of the information obtained;

(4) biographical information concerning the individuals and organizations consulted, their particular expertise, and their historical and genealogical relationship to the project area, as well as information concerning the persons submitting information or interviewed, their particular knowledge and cultural expertise, if any, and their historical and genealogical relationship to the project area;

(5) a discussion concerning historical and cultural source materials consulted, the institutions and repositories searched, and the level of effort undertaken, as well as the particular perspective of the authors, if appropriate, any opposing views, and any other relevant constraints, limitations or biases;

(6) a discussion concerning the cultural resources, practices and beliefs identified, and for the resources and practices, their location within the broad geographical area in which the proposed action is located, as well as their direct or indirect significance or connection to the project site;

5

- - - ' .. - .. - .. .. ..

(7) a discussion concerning the nature of the cultural practices and beliefs, and the significance of the cultural resources within the project area, affected directly or indirectly by the proposed project;

(8) an explanation of confidential information that has been withheld from public disclosure in the assessment;

(9) a discussion concerning any conflicting information in regard to identified cultural resources, practices and beliefs;

(10) an analysis of the potential effect of any proposed physical alteration on cultural resources, practices or beliefs; the potential of the proposed action to isolate cultural resources, practices or beliefs from their setting; and the potential of the proposed action to introduce elements which may alter the setting in which cultural practices take place, and;

(II) the inclusion of bibliography of references, and attached records of interviews, which were allowed to be disclosed.

Based on the inclusion of the above information, assessments of the potential effects on cultural resources in the project area and recommendations for mitigation of


ARCHIVAL RESEARCH Archival research focused on a historical documentary study involving both

published and unpublished sources. These included legendary accounts of native and

early foreign writers; early historical journals and narratives; historic maps and land

records such as Land Commission Awards, Royal Patent Grants, and Boundary

Commission records; historic accounts, and previous archaeological project reports.

INTERVIEW METHODOLOGY Interviews are conducted in accordance with Federal and State laws and

guidelines. Individuals and/or groups who have knowledge of traditional practices and beliefs associated with a project area or who know of historical properties within a project area are sought for consultation. Individuals who have particular knowledge of traditions passed down from preceding generations and a personal familiarity with the project area are invited to share their relevant information. Often people are recommended for their expertise, and indeed, organizations, such as Hawaiian Civic Clubs, the Island Branch of Office of Hawaiian Affairs, historical societies, Island Trail clubs, and Planning Commissions are depended upon for their recommendations of suitable informants. These groups are invited to contribute their input, and suggest further avenues of inquiry, as well as specific individuals to interview.

.. .. - .. - .. ..

.. - - .. .. - -If knowledgeable individuals are identified, personal interviews are sometimes

taped and then transcribed. These draft transcripts are returned to each of the participants for their review and comments. After corrections are made, each individual signs a release form, making the information available for this study. When telephone interviews occur, a summary of the information is often sent for correction and approval, or dictated by the informant and then incorporated into the document. Key topics discussed with the interviewees vary from project to project, but usually include: personal association to the ahupua'a, land use in the project's vicinity; knowledae of trlditional trails, gathering areas, water sources, religious sites; place names and their meanings; stories that were handed down concerning special places or events in the vicinity of the project area; evidence of previous activities identified while in the project vicinity.

In this case, letters briefly outlining the development plans along with maps of the

project area were sent to individuals and organizations whose jurisdiction includes

knowledge of the area with an invitation for consultation. Consultation was sought from Kai Markell, Office of Hawaiian Affairs, O'ahu Branch; Kanani Kagawa, Office of

Hawaiian Affairs, Kaua'i Island; Sandra Quinsaat and John Kruse of the Kaua'i Burial

Council. If cultural resources are identified based on the information received from these

organizations and additional infonnants, an assessment of the potential effects on the identified cultural resources in the project area and recommendations for mitigation of


PRWEer AREA AND VICINITY

The site is situated within Kapilimao Valley, Waimea Ahupua'a, Waimea

District, Island of Kauai (TMK (4) 1-2-02:1), northeast of Kekaha Town (Figure 3). In

1878, Valdemar Knudsen held crown leases on several large pieces of land including Kekaha. This was the beginning of the Kekaha Sugar Company (Wilcox 1996). The

project area is located on this leased Crown land which, through annexation, became a

part of ceded lands that were eventually to be held by the State of Hawai'i. Specifically, the proposed well site lies within lower Kapilimao Valley, the valley bounded by Hukipo

Road to the south, Huluhulunui Ridge to the east, Waiaka Ridge to the west, and upper

Kapilimao Valley to the north.

CULTURAL mSTORICAL CONTEXT

PAST POLITICAL BOUNDARIES During the reign ofMi'ilikakahi (between A. D. 1520 and 1540), the native

population had expanded throughout the Hawaiian Islands to a point where large political

districts were formed (Cordy 200 I, Kamakau 1991). Land was considered the property of

the king or a/j'j 'ai mo/cu (the al;'; who eats the island/district), which he held in trust for

the gods. The title of ali'j 'aj mo/cu ensured rights and responsibilities pertaining to the

land, but did not confer absolute ownership. The king kept the parcels he wanted, his higher chiefs received large parcels from him and, in tum, distributed smaller parcels to

lesser chiefs. The malca 'Binana (commoners) worked the individual plots ofland.

In general, several terms, such as mo/cu, ahupua 'a, 'iIi or 'jli 'j ina were used to

delineate various land sections. A district (moku) contained smaller land divisions (ahupua 'a) which customarily continued inland from the ocean and upland into the mountains. Extended household groups living within the ahupua'a were therefore, able

to harvest from both the land and the sea. Ideally, this situation allowed each ahupua 'a

to be self-sufficient by supplying needed resources from different environmental zones

(Lyons 1875:111). The 'ili 'Bina or 'ili were smaller land divisions next to importance to

the ahupua a and were administered by the chief who controlled the ahupua'a in which it

was located (ibid:33; Lucas 1995:40). The mo '0 'Bina were narrow strips ofland within

an ·iIi. The land holding of a tenant or hoa 'Bina residing in a ahupua 'a was called a

kuleana (Lucas 1995:61). The project area is located in the ahupuaa of Waimea which

literally translated is "reddish water" (Pukui el al. 1974:226).

TRADITIONAL SETTLEMENT PATTERNS The Hawaiian economy was based on agricultural production and marine

exploitation, as well as raising livestock and collecting wild plants and birds. Extended

household groups settled in various ahupua 'a. During pre-Contact times, there were

primarily two types of agriculture, wetland and dry land, both of which were dependent

upon geography and physiography. River valleys provided ideal conditions for wetland

kQJo (Colocasia esculenla) agriculture that incorporated pond fields and irrigation canals.

Other cultigens, such as frij (sugar cane, Saccharum ojf/Ctnaruma) and mai'a (banana,

Musa sp.), were also grown and, where appropriate, such crops as 'uala (sweet potato,

Ipomoea balalas) were produced. This was the typical agricultural pattem seen during traditional times on all the Hawaiian Islands (Kirch and Sahlins 1992, Vol. 1:5, 119;

Kirch 1985). Between A.D. 600-1100, sometimes referred to as the Developmental

9

- .. .. - - .. ..

Period, the major focus of permanent settlement continued to be the fertile and wellwatered windward valleys (Kirch 1985).

Heidel el a/. (1997:19) provide a synthesis of traditional land use which likely

occurred near the current project area. Intermittent streams and springs would have

supplied much needed water for the production of taro (and later, sugar cane). La'i

systems (pondfields for the cultivation of irrigated taro; Kirch 1985), permanent

residences, heiau, and/or terraces are considered likely to have been constructed in

gulches such as Kapilimao Valley, as they are areas which were tapped for water resources to irrigate lower elevation fields.

While taro was presumably cultivated in the valley, sweet potato, not requiring as

much water as taro cultivation, was likely a major staple food in the area. Thus, temporary use of upland areas likely consisted of resource-gathering zones, lower valley

gulches such as Kapilimao Valley utilized for temporary habitation and the acquisition of

resources (hydrological and faunal), the plain areas being utilized for subsistence,

habitation, and religious pursuits (10 'i, heiau, permanent structures, fishponds), and

coastal areas being utilized on a temporary basis for fishing (temporary camp sites) and

burial activities.

More succinctly, traditional land use within and near the present project area likely consisted of temporary occupation in these dry, Leeward lands. Kelly (1971:2) notes that Kekaha means aina ma/o '0 or dry land in the Hawaiian language. Activities

occurring in the valley, particularly lower valley reaches, presumably consisted of

acquiring avifaunal and other faunal resources and tapping the stream and nearby springs

for irrigable water, this important commodity funneled to lower elevations. Thus far

though, only minimal evidence has been found to support this claim. Profitable use of the

Kapilimao Stream waters would likely have occurred at the base of the valley, presently

the location of intensive sugarcane cultivation.

THE GREAT MAHELE In the 18405, traditional land tenure shifted drastically with the introduction of

private land ownership based on Western law. While it is a complex issue, many scholars

believe that in order to protect Hawaiian sovereignty from foreign powers, Kauikeaouli (Kamehameha III) was forced to establish laws changing the traditional Hawaiian

economy to that ofa market economy (Kame'eleihiwa 1992:169-70, 176; Kelly 1983:45,

10

.. .. .. - - - ..

- - - .. - - - -1998:4; Daws 1962:111; Kuykendall 1938 Vol. 1:145). The Great Miihele of 1848

divided Hawaiian lands between the king, the chiefs, the government, and began the

process of private ownership of lands. The subsequently awarded parcels were called

Land Commission Awards (LCAs). Once lands were thus made available and private

ownership was instituted, the maka 'iiinana (commoners}-ifthey bad been made aware

of the procedures-were able to claim the plots on which they had been cultivating and living. These claims did not include any previously cultivated but presently fallow land,

'okipii (on O'abu), stream fisheries, or many other resources necessary for traditional survival (Kelly 1983; Kame'eleihiwa 1992:295; Kirch and Sablins 1992). If occupation

could be established through the testimony of two witnesses, the petitioners were

awarded the claimed LCA and were issued a Royal Patent after which they could take

possession of the property (Chinen 1961:16). Archival research revealed that no Land

Commission Awards (LCA) occurred within the subject parcel or its environs.

HISTORIC LAND USE During the I 860s, rice cultivation occurred on the plains below Kapilimao valley.

This terminated with the inception of sugar cane cultivation in the latter portion of the

19111 century (Heidel et aI .. 1997). In 1878, Kekaha Sugar Company drilled its first artesian well in this dry area, the company finally incorporated in 1898. By 1959, the

whole plain was under sugar cane cultivation. Ranching activity also occurred during the late 19111 century, more so in upland reaches though.

From the I 870s through the early 1900s and later, during the middle of the 20111

century, ranching activities were prevalent near the project area. The land within and

near the project area reflect both ranching and sugar cane activities identified in the 1998 reconnaissance survey (Dega 1998).

SUMMARY

The "level of effort undertaken" to identify potential effect by a project to cultural

resources, places or beliefs (OEQC 1997) has not been officially defined and is left up to the investigator. A good faith effort can mean contacting agencies by letter, interviewing people who may be affected by the project or who know its history, research identifying

sensitive areas and previous land use, holding meetings in which the public is invited to testify, notifying the community through the media, and other appropriate strategies

based on the type of project being proposed and its impact potential. Sending inquiring

letters to organizations concerning development of a p,iece of property that has already

11

.. .. - - .. .. - - .. been totally impacted by previous activity and is located in an already developed

industrial area may be a "good faith effort". However, when many factors need to be

considered, such as in coastal or mountain development, a good faith effort might mean

an entirely different level of research activity.

-

In the case of the present parcel, letters of inquiry were sent to organizations

whose expertise would include the prnject area. Consultation was sought from Kai

Markell, Office of Hawaiian Affairs, O'abu Branch; Kanani Kagawa, Office of Hawaiian Affairs, Kaua'i Island; Sandra Quinsaat and John Kruse of the Kaua'i Burial Council.

Historical and cultural source materials were extensively used and can be found

listed in the References Cited portion of the report. Such scholars as ri, Kamakau,

Beckwith, Chinen, Kame'eleihiwa, Fornander, Kuykendall, Kelly, Handy and Handy,

Puku'i and Elbert, Thrum, Sterling, and Cordy have contributed, and continue to

contribute to our knowledge and understanding ofHawai'~ past and present. The works

of these and other authors were consulted and incorporated in the report where

appropriate. Land use document research was supplied by the Waihona 'Aina 2007 Data base.

CIA INQUIRY RESPONSE

As suaaested in the "Guidelines for Accessing Cultural Impacts" (OEQC 1997),

CIAs incorporating personal interviews should include ethnographic and oral history interview procedures, circumstances attending the interviews, as well as the results of this consultation. It is also permissible to include organizations with individuals familiar with cultural practices and features associated with the project area.

As stated above, consultation was sought from the Kai Markell, Office of

Hawaiian Affairs, O'abu Branch; Kanani Kagawa, Office of Hawaiian Affairs, Kaua'i

Island; Sandra Quinsaat and John Kruse of the Kaua'i Burial Council. No responses

were received from the contacted organizations. Therefore, no interviews were conducted for this property, as there were no interviewees identified.

Analysis of the potential effect of the project on cultural resources, practices or beliefs, its potential to isolate cultural resources, practices or beliefs from their setting,

and the potential of the project to introduce elements which may alter the setting in which

12

-

..

cultural practices take place is a requirement of the OEQC (No. 10, 1997). The visual

impact of the project from surrounding vantage points, is minimal. To our knowledge,

the project area has not been used for traditional cultural purposes within recent times.

Based on historical research and no response from the above listed contacts, it is

reasonable to conclude that Hawaiian rights related to gathering, access or other

customary activities within the project area will not be affected and there will be no direct

adverse effect upon cultural practices or beliefs.

CULTURAL ASSESSMEMNT

Based on lack of organizational of response, and the results of archival research, it

is reasonable to conclude that, pursuant to Act 50, the exercise of native Hawaiian rights,

or any ethnic group, related to gathering, access or other customary activities will not be

affected by the construction of the Kapilimao 0.5-millon gallon storage tank project on a

portion of Parcel 001. Because there were no cultural activities identified within the project area, there are no adverse effects.

We are in receipt of your above referenced letter and offer the following comments:

1. Section 1.1 - Project Background: The projections from Water Plan 2020, in regards to additional storage required, are unclear. Please provide clarification if 600,000 gallons of storage is required in Year 2000 and a total of 1.1 million gallons of storage is required in Year 2020.

2. Section 1.8 - Preliminary Cost Estimate: The EA lists a budgeted construction cost of $2.5 minion. Kauai Department of Water, recently provided the Department of Health, Safe Drinking Water Branch a construction cost estimate of $4 million for this project. Please revise EA to provide the correct cost estimate.

3. Section 4.3 - Compliance with the State of Hawaii's Drinking Water State Revolving Fund (DWSRF) Program Requirements: The EA erroneously lists the established date of the DWSRF as 1981 under the Safe Water Drinking

RE: Draft Envlroomentai Assessment, KapWmao O.5-MIIUon GaBon Storage Tank, KaplHmao, Kaua'l, TMK 1-2-001:002.

Dear Mr. Sakaguchi,

The Office of Hawaiian Affairs (OHA) is in receipt of your request for written comments regarding the applicant's Draft Environmental Assessment (DBA) for a O.S-million gallon storage tank for Kapilimao on Kaua'i. We have the following comments.

OHA realizes that this project is necessary for the public health and welfare for the residents in the area. However, the purpose of a DEA is to weigh the environmental effects of various alternatives to the proposed project. This DBA seems to assume that the project will go forward as planned. Even the invitation to comment lists as the subject, "Draft Environmental Assessment/Anticipated Finding of No Significant Impact (FONSI)". OHA understands that a FONSI determination may be anticipated for a project; however, it is a different matter to state this expected outcome repeatedly and assume that it will follow. Section 5 of the DBA, Alternatives to the Proposed Action is less than a page long. A DBA should analyze and compare the alternatives considered so that informed decision-making can result. Adhering to environmental assessment requirements from an early stage in a project can prevent unwanted cost and delay later on, as recent events dramatically have shown.

We appreciate that an effort was made to assess the impact on cultural resources, as required under Hawaii Revised Statutes, chapter 343, and that the County will stop work and contact the State Historic Preservation Division should iwi klipuna or cultural artifacts be uncovered.

Additionally, OHA would also like to suggest that the project area be landscaped with native or indigenous species. Any invasive species should also be removed. Doing so would not only serve as practical water-saving landscaping practices, but also serve to further the traditional Hawaiian concept of milama 'iina and create a more Hawaiian sense of place.

Finally, the lands which this project would impact are ceded lands, as are all submerged lands. As such, we request that they be treated with the respect due to them, as they are part of the 1.8 million acres of land that belong to the Hawaiian monarchy and were transferred to the state when Hawai'j became a U.S. state. In addition,.OHA urges that future documents refer to this parcel as ceded lands so that their special status is known to others and to facilitate their continued registry and the creation and maintenance of an accurate ceded lands inventory.

Thank you for the opportunity to comment If you have any further questions or concerns please contact Grant Arnold at (808) 594-0263 or [email protected].

Dear Mr. Namu'o:

Thank you for your October 16, 2oo71etier (HRD0712465C) on the Draft Environmental Assessment (EA)/Anticipated Finding of No Significant Impact (FONSI) for the Kapilimao O.5-Million Gallon Storage Tank project. Our responses follow:

The Draft EA discloses the environmental effects of the project, including the alternatives considered feasible for achieving the purpose and need for the project. As stated in the Draft EA 1.2 Purpose and Need, the O.5-million gallon (MG) storage tank is needed to fulfill the long-term storage needs of the Waimea-Kehaka water system. The County of Kauai Department of Water Is the agency responsible for the management, control, and operation of the County's water system. See Draft EA 1.1.

The Final EA will note that the project's location and siting considerations, including feasible alternatives, stem from the basic design of the Waimea-Kehaka water system which has other storage tanks sited at the same floor elevation (178 feet mean sea level (msl), spUIway elevation 196 feet, msl) as the O.5-MG storage tank. This elevation is critical to maintain water pressure in the system.

As stated in the Preface, the EA is prepared to meet the requirements of Chapter 343, Hawaii Revised Statutes, as amended, and Hawaii Administrative Rules Tille 11, State of Hawaii Department of Health, Chapter 200, Environmenlallmpact Statement Rules. As stated In the Rules Section 11-200-10, the contents of the EA Include, "the findings and reasons supporting the agency determination or anticipated determination.· Since the

document issued was a Draft EA, the anticipated determination was appropriate in the Draft EA. Moreover, as documented in the Draft EA, the early pre-assessment conSUltation p~ocess was undertaken and documented with comments and responses, as required by Title 11, Chapter 200, See Draft EA Appendix A.

The Draft EA Section 3.2 states that, to control erosion and runoff from the excavated and graded area, hydromulch covered with erosion control blankets will be used. Further, as stated in Section 3.2, temporary irrigation will be used untii the vegetation has become established. It is expected that eventually the cleared area will be similar to the surrounding area which is covered with lowland shrub vegetation of introduced species.

The Draft EA Summary and Section 1.3 states that the land is owned by the State of Hawaii. The Draft EA Section 1.5, Project Description, indicates the measures included in the design to protect the site and surrounding environment.

SUBJECT: DRAFT ENVIRONMENTAL ASSESSMENT FOR KAPILIMAO 0.5 MILLION GALLON STORAGE TANK, KEKAHA, WAIMEA, KAUAl, HAWAI'I TMK: 1-2-02-001 PW 9.07.152

Gentlemen,

We reviewed the subject draft environmental assessment. We offer the following comments:

1. At Sheet 1-10 of the Project Description, we are concerned with the height of the excavation into the hillside. The height is identified as 24 feet. Terraces or benches shall be constructed at vertical intervals of fifteen (15) feet, for cuts greater than 15 feet in height, unless modified by a soils report stating that the soil conditions will warrant a greater vertical height.

2. We can exempted the grading permit requirements if the site is owned and under the control of the Department of Water. Although we are exempting the grading permit, we expect the government agency (Department of Water) to monitor the grading activities including inspecting and making sure Best Management Practices (BMP's) for the project are complied with at all time during the construction of the project.

3. Best Management Practices (BMP's) shall be implemented at all times to the maximum extent practicable to prevent damage by sedimentation or erosion to streams, watercourses, natural areas and the property of others.

4. A grading permit may be required for the sites receiving the excess excavated material. The disposal sites shall also fulfill the requirements of the Sediment and Erosion Control Ordinance No. 808, The County's Kekaha Sanitary Landfill could use the excess material (2,800 Cubic Yards). Please contact our Solid waste Management Division in regards to the use of the material and acceptability of the material for cover material for the Kekaha Landfill. A grading permit will not be

- - - - - - - - -

Wilson Okamoto Corporation October 3, 2007 Page (2)

required for the disposal of the excess material at the Kekaha Landfill.

5. Flood and drainage comments needs to be solicited from the County's Flood Plain Coordinator due to the tank site being in close proximity to two unnamed drainage ways. Flood studies shall be submitted to the County's Flood Plain Coordinator for review and approval.

6. A detention basin is planned to retain the increase in storm runoffs and should also function as a sediment basin. Flood studies for the detention basin shall be submitted to the County's Flood Plain Coordinator for review and approval. We are presuming that the Water Department will be providing the maintenance for the basin such as scheduling cleaning out of the sediment and debris to maintain the required storage volume.

7. The outlet velocity for the detention basin is being concentrated and generally are erosive. Mitigating erosion control drainage measures needs to be provided to reduce the outlet velocity flows to be non-erosive.

8. The existing sheet flow drainage pattern needs to be maintained. We are concerned the driveway will function as a channel and will redirect and channel the storm flows to the lower land owners and cause nuisance flooding.

Thank you for this opportunity to provide our comments. Should you have any questions please contact me at (808) 241-6498.

A geotechnlcallnvesligation was Included as part of the design of the O.S-MG tank. The Final EA will state the geotechnlcallnvesligatlon Indicated pennanant cut slopes may be designed for gradients of 1H:1V or Hatter. Benches will not be required for slopes cut into basalt 50 feet or less In height. Thus, the site plan and the hillside excavation described In Section 1.5, Project Description, will be retained In the Final EA.

The Final EA Section 1.5, Project Description will include that the County of Kauai Department of Public Works will exempt the grading pennft for the tank sfte and driveway access. Grading and erosion control plans, including the Best Management Practlces (BMPs) that the contractor must use, wli be part of the design drawings. The BMPs will include the use of silt fences and rock filter berms to control runoff and sediment from the project site. Construction Inspections will be performed by the Department of Water who will also be monitoring the grading,

The Draft EA stated, during construction, slit fences and rock fiiter berms will be used to control sediment runoff from the O.S-MG tank and em8lgency generetor construction areas and to prevent sediment being carried Into the adjacent

Dear Mr. Antonio:

This is to follow up our November 14 and 20, 2007 telephone calis related to the Deparlment of Public Works October 3, 2007 comments on the Draft Environmental Assessment/ Anticipated Finding of No Significant Impact (FONSI) for the Kapilimao O.S-MUlion Gallon Storage Tank project.

The O.S-MG tank is located at the lower portion of Kapilimao Valley and about 200 ft west of an unnamed stream that drains the Valley. The USGS topographic map appears to show this unnamed stream nows Into the ditch system which was used for the fanner sugar cane fields which were located in the area between the Valley and Kekaha. See Figures 1.1 and 1.2 from the Draft Environmental Assessment and the enclosed.

A Drainage Study was done as part of the design work related to the O.5-MG tank drainage system, detention basin, and related drainage ouUets. The runoff from a 2-year, 1-hour stonn event was calculated for existing conditions and for post construction conditions. The calculated runoff for eXisting conditions was 6.07 cfs and for post construction 6.86 cis. The post construction condition Includes runoff to the detention basin and sheet now to the surrounding area. The detention basin has been sized to retain this increased runoff. The grading will promote sheet now to reduce erosion due to concentrated 1Iow. The change In runoff of 0.79 cfs should not affect the characteristics of the unnamed stream located east of the tank. See Figure 1.5 in the Draft EA.

- - - - - - - - - - -

7385-06 Letter to Mr. Mario Antonio, Flood Plain Coordinator Page 2 November 27, 2007

The topographic survey shows the bottom of the unnamed stream to be at around elevation +140 ft near the tank site. The tank floor elevation is at +178 ft, or about 35-40 ft above the stream elevation. This difference in elevation should be such that the tank will not be affected by flows from unnamed stream, except in the most extreme stonn event. See Figures 1.4 and 1.5 in the Draft EA.

The O.S-MG tank project site is located In Zone X, according to FIRM 1500020252E, September 16, 2005. The residential area of Kekaha is about 1.0 mile from the tank project site. Given, the ditch system and the distance of the residential area, and calculated change In runoff, the runoff from the O.5-MG tank project site. should not affect the residential areas.

The Draft EA, which was retumed with the October 3, 2007 comment letter, and the October 3, 2007 comment letter are enclosed.

Please provide any comments that you may have so the Department of Water can complete the EA process. If you need additional infonnation, please call me at 808.946.2277.
