a. Provide the brief project summary to be published in the EQB Monitor, (approximately 50 words). The proposed Project is a continuation of work completed in 1980 to comply with the federal Rivers and Harbors Act. It would consist of excavating a navigable channel into Lake of the Woods and improving the existing harbors, including installing stabilization measures; adding boat slips and docks; and constructing two parking lots, one stormwater pond, and a new walking trail adjacent to the existing harbor.

b. Give a complete description of the proposed project and related new construction, including infrastructure needs. If the project is an expansion include a description of the existing facility. Emphasize: 1) construction, operation methods and features that will cause physical manipulation of the environment or will produce wastes, 2) modifications to existing equipment or industrial processes, 3) significant demolition, removal or remodeling of existing structures, and 4) timing and duration of construction activities. The proposed Project is a continuation of work completed in 1980 to comply with the federal Rivers and Harbors Act. It would consist of excavating a navigable channel into Lake of the Woods from the existing north and south harbors. Approximately 0.50 mile of an existing navigable channel would be excavated, if necessary, to a depth of approximately 5 feet. Channel construction at the Taylor Road bridge, located on County Road 74/Taylor Road NE, would include installing sheet pile and stop logs. Harbor improvements would include installing stabilization measures, adding approximately 112 boat slips in the north harbor and 68 boat slips in the south harbor, removing vegetation to provide safe access to docks, constructing a 1.12-acre northwest parking lot and associated 0.18-acre stormwater pond, constructing a 2.0-acre southeast parking lot, and constructing approximately 560 feet of 8-foot-wide bituminous walking trail in an approximately 1.25-acre area adjacent to the existing north harbor. An approximately 5.5-acre space would also be available adjacent to the northwest parking lot for potential spoil storage (see Figure 3).

page 3

Construction is anticipated to occur for 1 month in the winter for lakeward channel excavation and for 6 months during open water months for construction of the remainder of the Project. The Project would meet all applicable federal, state, and local requirements. All construction work would be performed during hours specified by permits and local requirements.

9. Land use:

page 5

a. Describe: i. Existing land use of the site as well as areas adjacent to and near the site, including parks,

trails, prime or unique farmlands. The Project area includes a large harbor (divided into a north harbor and south harbor by a peninsula), a channel that crosses under County Road 74 and flows into Lake of the Woods approximately 850 feet northeast of the north harbor, and open grassy areas with a small pocket of trees in the southeastern corner. The general land use within the Project area consists of an open water harbor and channel, wetlands, and open grassland where the proposed spoil storage, parking lots and stormwater pond would be located (see Figure 4). The railroad grade shown in Figure 2 along the northern boundary of the Project area is no longer present. The land use adjacent to the Project area is described as follows:

• The peninsula that divides the harbor into a north harbor and south harbor contains several trailer homes and pockets of grassland and wooded areas. Trailer homes are within 50 feet of the harbor shoreline and are adjacent to the Project area. A paved walking trail enters the Project area approximately 15 feet from the south edge of the proposed southeast parking lot and continues along the entire shoreline of the harbor, exiting the Project area approximately 15 feet from the northwest corner of the proposed spoil storage area. 1st Avenue NE is approximately 20 feet from the west side of the proposed stormwater pond. City RV Park Road is approximately 120 feet from the south side of the north harbor.

• County Road 74 is approximately 40 feet from the northeast side of the channel. Lake of the Woods is approximately 500 feet from the east side of County Road 74.

• Mackenzie Street NE is approximately 90 feet from the southern edge of the proposed southeast parking lot. 3rd Avenue NE is approximately 120 feet from the southern edge of the south harbor. Lakeview Park is approximately 100 feet from the east side of the proposed southeast parking lot.

Although land use within the Project area is classified as cropland by the National Land Cover Database 2016 data, there are no agricultural fields present.

ii. Plans. Describe planned land use as identified in comprehensive plan (if available) and any

other applicable plan for land use, water, or resources management by a local, regional, state, or federal agency. The Roseau County Local Water Management Plan 2010-2019 is recognized as the Roseau County Soil and Water Conservation District’s comprehensive plan (Roseau County Soil and Water Conservation District 2009). The Roseau County Local Water Management Plan identifies priority water resource concerns in the county and lists strategies for future protection and management of land and water resources throughout the county. The Warroad River Watershed District has adopted the Lake of the Woods Watershed Comprehensive Watershed Management Plan 2019-2029, also referred to as Lake of the

page 6

Woods One Watershed, One Plan (1W1P), as of October 22, 2019. The 1W1P identifies prioritized issues within the watershed and implementation strategies that result in measurable resource improvements (Houston Engineering, Inc. 2019).

iii. Zoning, including special districts or overlays such as shoreland, floodplain, wild and scenic rivers, critical area, agricultural preserves, etc. The Roseau County Floodplain Management Ordinance and the Warroad, MN Code of Ordinances, Section 151.020, define a Floodway District as those areas within Zone AE that have a floodway delineated, as shown on the Flood Insurance Rate Map (Roseau County 2017; City of Warroad 2017). The Floodway Districts are overlay districts that are superimposed on all existing zoning districts within the county and the city. Upon review of the Flood Insurance Rate Map developed by the Federal Emergency Management Agency’s National Flood Insurance Program (1987), it was determined that the Project area is within the Flood Hazard Zone AE (1% Annual Chance Flood Hazard). The floodplain ordinances for the county and city classify extraction/fill of materials, storage of materials, and marina structures as conditional uses (Roseau County 2017; City of Warroad 2017). The Roseau County Shoreland Management Ordinance and the Warroad, MN Code of Ordinances, Section 153.008, define shoreland as land within 1,000 feet from the ordinary high water level of a lake, pond, or flowage; and land 300 feet from a river or stream, or the landward extent of a floodplain designated by ordinance on a river or stream, whichever is greater (Roseau County 1993; City of Warroad 2017). Both Roseau County and the City of Warroad classify the Lake of the Woods as a General Development Lake, which is defined as a highly developed, multi-use area that requires minimum regulations in order to provide beneficial use of public waters to the general public, and provide guidance for future commercial, industrial and residential growth along protected waters (Roseau County 1993; City of Warroad 2017). The City of Warroad’s zoning map shows the Project area within the Public Recreation and Forest Reserve (P-1) Zoning District (City of Warroad 2013). Public shoreline frontage, landing docks, and harbors are listed as permitted uses within the zoning district, and off-street parking is listed as a permitted accessory use (City of Warroad 2017). Upon review of the Minnesota Department of Natural Resources (DNR) Wild & Scenic Rivers Program (2020a), it was determined that there are no wild and scenic rivers within or adjacent to the Project area. Lake of the Woods is designated as a wild rice lake by DNR and is further described in EAW Item 13.b. Beyond the resources described prior to and following this section, no other additional critical areas within or immediately adjacent to the Project area were identified.

b. Discuss the project’s compatibility with nearby land uses, zoning, and plans listed in Item 9a above, concentrating on implications for environmental effects. Warroad is the only American port on the Lake of the Woods. The city offers several recreational opportunities, including camping, fishing, and boating. This Project is compatible with nearby

page 7

land uses because it would improve access for recreational watercraft and reduce the risk of flood damage. The primary environmental effect of the proposed Project would be along the navigable channel out into Lake of the Woods where the excavation would occur. In addition, land cover would change from open grassland to impervious surface where the proposed parking lots and walking trail would be located. The spoil storage area would also be temporarily changed from an open grassy area to storage for spoil from the channel excavation until vegetative cover can be re-established. Applicable federal, state, and local permits and approvals would be required for construction and operation of the Project (see previous Table 4). In many cases, the issuance of these permits and approvals, and conditions therein, will address issues concerning environmental effects.

c. Identify measures incorporated into the proposed project to mitigate any potential incompatibility as discussed in Item 9b above. Per the Roseau County Shoreland Management Ordinance, Section 5.05.B, Topographic Alterations/Grading and Filling, Item 3, a grading and filling permit will be required for the movement of more than 10 cubic yards of material on steep slopes or within shore or bluff impact zones, and for the movement of more than 50 cubic yards of material outside of steep slopes and shore and bluff impact zones. In addition, in Item 5 states that excavations where the intended purpose is connection to a public water, such as boat slips, canals, lagoons, and harbors, require an excavation permit from Roseau County. Permission for excavations may be given only after the Commissioner has approved the proposed connection to public waters (Roseau County 1993). Per the Roseau County Shoreland Management Ordinance and the Warroad, MN Code of Ordinances, Section 153.061, the setback provisions for General Development Lakes is 75 feet from the ordinary high water level (Roseau County 1993; City of Warroad 2017). Per the Roseau County Shoreland Management Ordinance, Section 5.05.B, Topographic Alterations/Grading and Filling, Item 4(K), and the Warroad, MN Code of Ordinances, Section 153.064, Shoreland Alterations, the placement of natural rock riprap, including associated grading of the shoreline and placement of a filter blanket, is permitted if the finished slope does not exceed 3 feet horizontal to 1 foot vertical, the landward extent of the riprap is within 10 feet of the ordinary high water level, and the height of the riprap above the ordinary high water level does not exceed 3 feet (Roseau County 1993; City of Warroad 2017). Per the Roseau County Floodplain Management Ordinance, Section 5.3, Conditional Uses, and the Warroad, MN Code of Ordinances, Section 151.033, Standards for Floodway Conditional Uses, a conditional use permit will be applied for (Roseau County 2017; City of Warroad 2017). Per the Warroad, MN Code of Ordinances, Section 153.066, Stormwater Management, constructed stormwater ponds require documentation provided by a qualified individual that the design and installation methods for the constructed stormwater pond are consistent with the field office technical guide of the Roseau County Soil and Water Conservation District (City of Warroad 2017).

10. Geology, soils and topography/land forms: a. Geology - Describe the geology underlying the project area and identify and map any susceptible

geologic features such as sinkholes, shallow limestone formations, unconfined/shallow aquifers, or karst conditions. Discuss any limitations of these features for the project and any effects the project could have on these features. Identify any project designs or mitigation measures to address effects to geologic features. Glacial Lake Agassiz once covered much of the northwest corner of Minnesota (and into Canada) during the last ice age. The surficial geology of the Project vicinity is characterized by glacial sediments deposited during the late Wisconsin Glaciation (between 11,700 and 14,000 years ago). Glacial lake sediments and tills are mapped in this area (see Figure 5). Specifically, in the Project area, sandy sediments described as fine-grained sand to silt were derived by till, washed by waves, and deposited along the shoreline of Lake of the Woods (Lusardi et al 2019). Bedrock underlying the glacial deposits occurs between 100 to 200 feet below ground surface (see Figure 6). The underlying bedrock consists of a Neoarchean Age intrusion in the Wabigoon Subprovince (of the Superior Province). The bedrock is composed of gabbro, peridotite, pyroxenite, lamprophyre, and metamorphic equivalents (Jirsa et al 2011; see Figure 7). Based on the described geology, karst features such as sinkholes, springs, or shallow limestone formations are not a concern for the proposed Project. Shallow groundwater (less than 20 feet) is present in the Project area (see Figure 8). The depth to water is expected to decrease with decreasing distance to the lake and land elevation. The Project lies within the boundaries of the City of Warroad’s Drinking Water Supply Management Area, which has a vulnerability classification of Low. The nearest domestic wells are located at least 0.5 mile upgradient to the west (Minnesota Department of Health [MDH] 2019). Most of the drinking water in the surrounding area is supplied by the City of Warroad public water system. Adverse impacts on the shallow aquifer from Project activities are not expected based on the proposed construction activities.

b. Soils and topography - Describe the soils on the site, giving NRCS (SCS) classifications and descriptions, including limitations of soils. Describe topography, any special site conditions relating to erosion potential, soil stability or other soils limitations, such as steep slopes, highly permeable soils. Provide estimated volume and acreage of soil excavation and/or grading. Discuss impacts from project activities (distinguish between construction and operational activities) related to soils and topography. Identify measures during and after project construction to address soil limitations including stabilization, soil corrections or other measures. Erosion/sedimentation control related to stormwater runoff should be addressed in response to Item 11.b.ii. The Project area lies along the southwestern shoreline of Lake of the Woods, north of the mouth of the Warroad River. The topography is relatively flat, and land elevations in the Project area are approximately 1,062 to 1,072 feet above mean sea level (see Figure 9). The Project area is comprised of 31.9 percent (6.9 acres) Zippel very fine sandy loam, 0 to 2 percent slopes, and 22.7 percent (4.9 acres) Sago Muck, 0 to 1 percent slopes (see Figure 10). The remaining 45.4 percent (9.8 acres) of the Project area is covered by water. The soil types are coarse-loamy and coarse-silty and are considered poorly drained (Zippel) to very poorly drained (Sago).

page 9

The Natural Resources Conservation Service erosion hazard ratings describes the hazard of soil loss for off-road/off-trail areas after disturbance activities that expose the soil surface. The hazard has four rankings that range from slight to very severe. Within the Project area, the soils are rated as slight, meaning that erosion is unlikely under ordinary climatic conditions. The proposed Project would disturb or remove approximately 23,039 cubic yards relating to excavation of soil and sediment for the harbor, channel, and stormwater pond. Potential disturbance and/or grading for the parking lots, spoil storage area, and walking trail is estimated at 8.8 acres. As with any ground disturbance, construction of the Project has the potential for soil compaction, erosion, and sedimentation as a result of construction activities. Given the predominance of poorly drained to very poorly drained soils at the site, soil compaction during construction may be a concern. Soil disturbance would be minimized to the extent possible, but the overall objectives of the Project require the removal of sediment (dredging). The sediments removed during dredging would be stored in the spoil storage area. Soils in the Project area that are free of organics and debris may be used in grading and backfilling where needed. Upon completion of construction, operation of the Project is not anticipated to adversely impact soils. Stormwater runoff would be managed via the measures further described in EAW Item 11.b.ii. Permits for stormwater as well as erosion and sediment control are also discussed in EAW Item 11.b.ii.

11. Water resources: a. Describe surface water and groundwater features on or near the site in a.i. and a.ii.

below. i. Surface water - lakes, streams, wetlands, intermittent channels, and county/judicial ditches.

Include any special designations such as public waters, trout stream/lake, wildlife lakes, migratory waterfowl feeding/resting lake, and outstanding resource value water. Include water quality impairments or special designations listed on the current MPCA 303d Impaired Waters List that are within 1 mile of the project. Include DNR Public Waters Inventory number(s), if any. Surface water features in the Project area include the north and south harbor and the Lake of the Woods. The Warroad River flows through the city south of the Project area and outlets to Lake of the Woods (see Figure 11). DNR’s Minnesota Wetland Inventory documents freshwater ponds, freshwater forested wetlands, and freshwater emergent wetlands in the Project area (DNR 2020b). Lake of the Woods (Public Water Number 392000201) is designated as a protected public water by DNR. Surface water resources were identified via desktop analysis using the National Hydrography Dataset (United States Geological Survey [USGS] 2020a) and DNR’s Minnesota Wetland Inventory (DNR 2020b). Impaired waters on the Minnesota Pollution Control Agency (MPCA) 303(d) list within 1 mile of the Project area include Lake of the Woods and Warroad River. Lake of the Woods (AUID 39-0002-01) is listed as impaired for aquatic life, aquatic consumption due to high mercury in fish tissue, and high amounts of nutrients and chlorophyll-a. Warroad River (AUID: 09030009-502) is listed as impaired for aquatic consumption as a result of high

page 10

mercury in fish tissue. No other impairments are listed within 1 mile of the Project area in MPCA’s list of 303(d) Impaired Waters (MPCA 2020a).

ii. Groundwater – aquifers, springs, seeps. Include: 1) depth to groundwater; 2) if project is within a MDH wellhead protection area; 3) identification of any onsite and/or nearby wells, including unique numbers and well logs if available. If there are no wells known on site or nearby, explain the methodology used to determine this. Per MDH’s Source Water Protection Web Mapping Application (2020), the entire Project area is within the City of Warroad’s Drinking Water Supply Management Area. There are no mapped Special Wells or Boring Construction Areas in the Project area. MDH’s Minnesota Well Index (2019) indicates that one active test well (Well ID number 269357) is present within the disturbance footprint of the Project area. The USGS’s Minnesota Active Water Level Network (2020b) does not document any active water level network wells near the Project. The Minnesota Natural Resource Atlas depth to water table indicates that the Project area has depths to water table generally ranging from 0 to 10 feet, as shown in previous Figure 8 (Natural Resources Research Institute 2020). The Rapid Watershed Assessment for the Roseau watershed lists primary groundwater quality issues in this watershed as high dissolved solids in deeper aquifers, manganese, arsenic, chloride, sulfate, and nitrate. Farming practices on highly permeable soils, aging septic systems, stormwater runoff, and improperly abandoned wells all pose significant threats to groundwater quality throughout the region. While drinking water quality is the primary consideration, the quality of groundwater moving to lakes and recharging streams is also a concern (Natural Resources Conservation Service 2009). The Lake of the Woods Watershed 1W1P area encompasses portions of Roseau and Lake of the Woods Counties and the entire Warroad River Watershed District. The Project area is located in the Warroad River Watershed District, which consists of a series of smaller drainages, all of which drain into Lake of the Woods. The 1W1P (Houston Engineering, Inc. 2019) recognizes priority issues to groundwater in the watershed, including the following:

• Insufficient knowledge of groundwater condition in private drinking water sources (wells)

• Protection of groundwater supplies from elevated levels of nitrates • Protection of groundwater supplies from elevated bacteria (E. coli and total coliform) • Insufficient knowledge of groundwater resource supplies

b. Describe effects from project activities on water resources and measures to minimize or mitigate

the effects in Item b.i. through Item b.iv. below. i. Wastewater - For each of the following, describe the sources, quantities and composition of

all sanitary, municipal/domestic and industrial wastewater produced or treated at the site. 1) If the wastewater discharge is to a publicly owned treatment facility, identify any

pretreatment measures and the ability of the facility to handle the added water and waste loadings, including any effects on, or required expansion of, municipal wastewater infrastructure.

page 11

No wastewater discharge would be produced by the Project. The Project would not require any operations and maintenance buildings, and would not house permanent, on-site staff. Upon completion of construction, there would not be any buildings or structures fitted with running water or restroom facilities, and there would be no need for sanitary or industrial wastewater treatment.

2) If the wastewater discharge is to a subsurface sewage treatment systems (SSTS), describe the system used, the design flow, and suitability of site conditions for such a system. No wastewater discharge would be produced by the Project. The Project would not have any buildings equipped with potable water or restrooms. As such, a subsurface sewage treatment system would not be installed.

3) If the wastewater discharge is to surface water, identify the wastewater treatment methods and identify discharge points and proposed effluent limitations to mitigate impacts. Discuss any effects to surface or groundwater from wastewater discharges. No wastewater discharge would occur as a result of the Project.

ii. Stormwater - Describe the quantity and quality of stormwater runoff at the site prior to and post construction. Include the routes and receiving water bodies for runoff from the site (major downstream water bodies as well as the immediate receiving waters). Discuss any environmental effects from stormwater discharges. Describe stormwater pollution prevention plans including temporary and permanent runoff controls and potential BMP site locations to manage or treat stormwater runoff. Identify specific erosion control, sedimentation control or stabilization measures to address soil limitations during and after project construction. The Project area receives stormwater runoff through an existing stormwater pipe that discharges stormwater from the adjacent RV park and neighborhood roads to the north harbor. The stormwater flows through the harbor and enters Lake of the Woods through a channel crossing under County Road 74/Taylor Road NE. Improvements to stormwater runoff as a result of Project construction would include construction of a stormwater pond adjacent to the proposed northwest parking lot. Construction activities would include excavating a navigable channel out into Lake of the Woods and improving the existing harbors, including installing stabilization measures and adding boat slips and docks. Excavation and stabilization activities would disturb soils, leaving them potentially vulnerable to erosion. To minimize disturbance of soils and vegetation, dredging activities would occur during the winter months when equipment can operate from the ice. Because the Project would disturb more than 1 acre, the Project would require a Construction Stormwater Permit under the National Pollutant Discharge Elimination System (NPDES) program, administered by MPCA. As a part of the NPDES permit application, the City would be required to develop a Storm Water Pollution Prevention Plan (SWPPP), which would require identification and implementation of erosion and sediment control best management practices (BMPs) to be complied with during construction. BMPs would include a combination of structural and non-structural controls to ensure the maximum erosion and sediment control possible. Structural controls may include silt fence, filter

page 12

logs/wattles, erosion control blankets, and access pads (to prevent sediment tracking onto public roads). Non-structural practices may include vegetative buffers, stabilization practices such as seed and mulch, topsoil segregation, use of construction sequencing, and working during winter months. In addition, the NPDES permit would require that stormwater management practices be designed to treat a volume of water (referred to as the water quality volume) based on the amount of impervious surface being constructed. The City would determine the total impervious surface area for the Project in order to determine the total water quality volume that must be treated during the NPDES and SWPPP permit application process. Permanent stormwater treatment would be provided via the construction of a permanent stormwater pond adjacent to the proposed northwest parking lot. Although a Minnesota Pollution Control Agency State Disposal System (SDS) permit for the management of dredged materials is not required for the Project, the Project intends to prepare and submit a formal Notification to Manage Dredged Material Without a Permit to the Minnesota Pollution Control Agency. The project will implement BMPs described in the Minnesota Pollution Control Agency “Best Management Practices for the Management of Dredged Material”. Additionally, 401 Water Quality Certification (401 Certification) would also be required for the proposed project. Project activities regulated under section 404 of the Clean Water Act and specifically return discharge/effluent water from the spoil storage area would require 401 Certification from the Minnesota Pollution Control Agency. The Project intends to apply for 401 Certification as part of the section 404 permitting process during final design. Following construction of the Project, general stormwater flow patterns would be improved with the addition of a stormwater pond. Stabilization measures in the harbor and channel would reduce erosion and sedimentation.

iii. Water appropriation - Describe if the project proposes to appropriate surface or groundwater (including dewatering). Describe the source, quantity, duration, use and purpose of the water use and if a DNR water appropriation permit is required. Describe any well abandonment. If connecting to an existing municipal water supply, identify the wells to be used as a water source and any effects on, or required expansion of, municipal water infrastructure. Discuss environmental effects from water appropriation, including an assessment of the water resources available for appropriation. Identify any measures to avoid, minimize, or mitigate environmental effects from the water appropriation. The Project would not require appropriating surface or groundwater for any construction activities. Project activities would primarily include dredging operations and construction of parking lots and a walking trail. As such, a Water Appropriation Permit from DNR would not be required.

iv. Surface Waters a) Wetlands - Describe any anticipated physical effects or alterations to wetland features

such as draining, filling, permanent inundation, dredging and vegetative removal. Discuss direct and indirect environmental effects from physical modification of wetlands,

page 13

including the anticipated effects that any proposed wetland alterations may have to the host watershed. Identify measures to avoid (e.g., available alternatives that were considered), minimize, or mitigate environmental effects to wetlands. Discuss whether any required compensatory wetland mitigation for unavoidable wetland impacts will occur in the same minor or major watershed, and identify those probable locations. Based on a desktop delineation using the DNR’s Minnesota Wetland Inventory and the National Hydrography Dataset (DNR 2020b; USGS 2020a), construction of the channel and stabilization activities in the harbor would result in 104,544 square feet (2.4 acres) of impacts on wetlands in the Project area (see Table 5 and Figure 11). Approximately 23,040 cubic yards of sediment would be removed for construction of navigable channel into Lake of the Woods. Table 5. Permanent Wetland Impacts in the Project Area

Wetland Type Acres Freshwater Emergent Wetland 2.1 Freshwater Forested Wetland 0.3

Total Wetland Impacts 2.4 Impacts on wetlands would be minimized during dredging activities through BMPs to avoid or minimize turbidity/sedimentation while physically altering the water features. To minimize disturbance of wetlands and vegetation, dredging activities would occur during the winter months when equipment can operate from the ice. Potential impacts on wetlands would occur from sediment discharges associated with erosion and stormwater runoff, hydrologic modifications, and the establishment of noxious weeds. Most of these effects could be reduced or eliminated using BMPs. BMPs would prevent the spread of invasive species, and disturbed wetland areas would be re-seeded with native vegetation. Prior to construction, the Project area would be delineated, and wetland impact minimization would follow the Minnesota Wetland Conservation Act and the federal Clean Water Act. The City of Warroad will coordinate with the United States Army Corps of Engineers and the United States Coast Guard to determine the level of permitting required. It is likely that a Section 10 permit and a Section 404 permit would be required for impacts on wetlands and waters of the US.

b) Other surface waters- Describe any anticipated physical effects or alterations to surface water features (lakes, streams, ponds, intermittent channels, county/judicial ditches) such as draining, filling, permanent inundation, dredging, diking, stream diversion, impoundment, aquatic plant removal and riparian alteration. Discuss direct and indirect environmental effects from physical modification of water features. Identify measures to avoid, minimize, or mitigate environmental effects to surface water features, including in-water Best Management Practices that are proposed to avoid or minimize turbidity/sedimentation while physically altering the water features. Discuss how the project will change the number or type of watercraft on any water body, including current and projected watercraft usage.

Construction of the channel and stabilization activities in the harbor would result in 378,972 square feet (8.7 acres) of impacts on freshwater pond and lake habitat in the Project area (see

Table 6). Approximately 23,040 cubic yards of sediment would be removed for construction of navigable channel into Lake of the Woods. Table 6. Surface Waters

Other Surface Waters Acres Freshwater Pond 6.8 Lake 1.9

Total Wetland Impacts 8.7 The direct environmental effect on other surface waters would be the temporary loss of submersed aquatic vegetation, and the physical disruption and removal of sediments and the invertebrates that live there. Dredged areas would be recolonized by plants and invertebrates within several years following construction.

12. Contamination/Hazardous Materials/Wastes: a. Pre-project site conditions - Describe existing contamination or potential environmental hazards

on or in close proximity to the project site such as soil or ground water contamination, abandoned dumps, closed landfills, existing or abandoned storage tanks, and hazardous liquid or gas pipelines. Discuss any potential environmental effects from pre-project site conditions that would be caused or exacerbated by project construction and operation. Identify measures to avoid, minimize or mitigate adverse effects from existing contamination or potential environmental hazards. Include development of a Contingency Plan or Response Action Plan. No listings identifying contamination or potential environmental hazards were found in the Project area based on a review of listings in the MPCA (2020b) and Minnesota Department of Agriculture (2020) “What’s in My Neighborhood?” (WIMN) databases. A search of the surrounding area up to 0.25 mile away found five listings in the MPCA WIMN database and no listings in the Minnesota Department of Agriculture WIMN database (see Figure 12). The identified listings included the following sites:

• USCOE Warroad Harbor Dredge (Lake of the Woods – 0.24 mile east). This listing was for an industrial State Disposal System Permit that is now inactive. The permit end date was listed as May 12, 2008.

• Lake of the Woods Resort (1201 Lake Street NE– 0.17 mile southeast). This property is listed as a tank and petroleum remediation leak site. Two active gasoline underground storage tanks (1,000 and 2,000 gallons) and three removed gasoline underground storage tanks (300, 560, and 2,000 gallons) are/were registered to the property. A leak was discovered in 1991 (likely when the older underground storage tanks were removed). A remedial investigation, corrective actions, and monitoring occurred onsite. The site was closed on August 18, 2010. No institutional controls are currently in place.

• Warroad Area Forestry Office (1011 Lake Street NE – 0.15 mile southeast). This site was reported as a petroleum remediation leak site. A leak was reported on June 15, 1998.

page 15

A Remedial Investigation Report was completed, and the site was later closed on February 28, 1999.

• Thrifty White Pharmacy 780 (310 Lake Street NE – 0.17 mile south). This business is currently listed as a very small quantity hazardous waste generator. Pharmaceutical wastes were reported for disposal by a hazardous waste transport service.

• Young Manor Apartments (601 Mackenzie Street NE – 0.25 mile southwest). This property was identified in the tanks database for a 10,000-gallon fuel oil underground storage tank that was removed in 1994 or 1995. The site is no longer considered active, and no institutional controls are in place. No associated spill or leak records were found in association with the site.

Contamination relating to leaking underground storage tanks was previously reported at the Lake of the Woods Resort and Warroad Area Forestry Office properties. Both cases are now closed, and the properties are located cross-gradient to downgradient of the Project area. Based on a review of the listed sites, contamination impacts on the Project are not expected. A Construction Contingency Plan would be developed to aid the contractor in the event that unexpected stained soils or other indications of contamination are discovered. They would be instructed to stop work and follow certain steps until the potential contaminants can be properly evaluated by a professional specializing in the identification and characterization of contamination.

b. Project related generation/storage of solid wastes - Describe solid wastes generated/stored during construction and/or operation of the project. Indicate method of disposal. Discuss potential environmental effects from solid waste handling, storage and disposal. Identify measures to avoid, minimize or mitigate adverse effects from the generation/storage of solid waste including source reduction and recycling. Solid waste generated in the Project area during construction would be typical for a construction project involving earthwork. All non-recyclable solid wastes generated by construction of the proposed Project would be disposed of properly in a permitted, licensed solid waste facility. Most of the waste generated would be in the form of excess soil, sediment, vegetation, and trees generated by clearing and dredging within the proposed construction footprint. During Project construction, excavation of soil and sediment would need to occur within the Project limits. Preliminary design would consider the optimal amount of soil and sediment removal needed to achieve Project objectives. Most of the excess soil and sediments material would be hauled offsite and disposed of in accordance with state and federal requirements. The contractor would be responsible for any characterizing requirements associated with disposal. If during construction contaminated soils were encountered, the response would be handled consistent with MPCA requirements and the Project’s Construction Contingency Plan or Response Action Plan. No solid waste generation during operation is anticipated.

page 16

c. Project related use/storage of hazardous materials - Describe chemicals/hazardous materials used/stored during construction and/or operation of the project including method of storage. Indicate the number, location and size of any above or below ground tanks to store petroleum or other materials. Discuss potential environmental effects from accidental spill or release of hazardous materials. Identify measures to avoid, minimize or mitigate adverse effects from the use/storage of chemicals/hazardous materials including source reduction and recycling. Include development of a spill prevention plan. No aboveground storage tanks or underground storage tanks are planned for permanent use in conjunction with this Project. Temporary storage tanks for petroleum products may be located within the Project limits for refueling construction equipment during construction. Appropriate measures would be taken during construction to avoid spills that could contaminate groundwater or surface water in the Project area. Spill kits would be on hand during construction to address minor spills and releases from equipment. If a leak or spill were to occur during construction, immediate response and appropriate action to remedy the situation would be taken in accordance with MPCA guidelines and regulations. These response actions would be further detailed in the Spill Prevention, Control, and Countermeasure Plan developed for the Project.

d. Project related generation/storage of hazardous wastes - Describe hazardous wastes generated/stored during construction and/or operation of the project. Indicate method of disposal. Discuss potential environmental effects from hazardous waste handling, storage, and disposal. Identify measures to avoid, minimize or mitigate adverse effects from the generation/storage of hazardous waste including source reduction and recycling. Typical construction wastes are anticipated. Hazardous materials or petroleum products would be limited and primarily associated with fuel and oils for construction equipment. The contractor would be required to properly protect and containerize (e.g., secondary containment) bulk hazardous materials and petroleum products that would be stored onsite. Although spills of these materials are not common, any spills of reportable quantities that would occur would be reported to the Minnesota Duty Officer, and the contractor would clean up spilled material and respond according to state requirements.

13. Fish, wildlife, plant communities, and sensitive ecological resources (rare features): a. Describe fish and wildlife resources as well as habitats and vegetation on or in near the site.

The Project area is in northeast Roseau County in Warroad, Minnesota, along the shoreline of Lake of the Woods. It is located within the Laurentian Mixed Forest ecological province—Northern Minnesota and Ontario Peatlands section, Agassiz Lowlands subsection—as defined by DNR (DNR 2003). This area is described as a flat, poorly drained lake plain (DNR 2003). Vegetation in this subsection is dominated by wet prairie and conifer-bog (DNR 2003). The Project area currently consists of an excavated channel within upland area adjacent to Lake of the Woods and extends into the littoral and limnetic zones of Lake of the Woods. Vegetation of the lake and channel sections of the Project area is dominated by hybrid cattail (Typha x. glauca) and various submerged plants (Potamogeton spp.). Upland areas within the Project area are dominated by species associated with urban development, such as smooth brome grass (Bromus inermis).

page 17

Common wildlife located in the Project area include species that have adapted to live in urban areas, including small mammals and songbirds. A wide variety of fish species is likely to reside in the Project area due to the hydrologic connection to Lake of the Woods. DNR lists 30 different species of fish as occurring in Lake of the Woods (DNR 2019).

b. Describe rare features such as state-listed (endangered, threatened or special concern) species, native plant communities, Minnesota County Biological Survey Sites of Biodiversity Significance, and other sensitive ecological resources on or within close proximity to the site. Provide the license agreement number (LA- 1022) and/or correspondence number (ERDB _____________) from which the data were obtained and attach the Natural Heritage letter from the DNR. Indicate if any additional habitat or species survey work has been conducted within the site and describe the results. DNR regulates the harvesting and possession of wild rice (Zizania palustris), including the removal of plants, under Minnesota State Statute 84.15. Wild rice is known to occur in Lake of the Woods (DNR 2008), and there is the potential that wild rice may occur in the waters of Lake of the Woods within the Project area (see Figure 13). The shoreline of Lake of the Woods is categorized as below minimum biodiversity significance threshold because of the lack of occurrences of rare species and natural features (DNR 2020c). Federally Listed Endangered and Threatened Species Section 7 of the Endangered Species Act of 1973, as amended, requires federal agencies to review any action that it funds, authorizes, or carries out to determine whether it may affect threatened, endangered, or proposed species, or listed critical habitat. Federal agencies (or their designated representatives) must consult with the United States Fish and Wildlife Service (USFWS) if any such effects may occur as a result of their actions. If a federal agency finds that an action would have no effect on listed species or critical habitat, it should maintain a written record of that finding that includes the supporting rationale. An official list of federally listed threatened, endangered, proposed, and candidate species that may occur within the Project area was provided through the USFWS online Information for Planning and Consultation tool (see Attachment B). Two species federally listed as threatened—northern long-eared bat (NLEB; Myotis septentionalis) and Canada lynx (Lynx Canadensis)—were identified as potentially occurring in the Project area. No critical habitat for either the NLEB or Canada lynx is located in the Project area. No known NLEB hibernacula occur within 0.25 mile of the Project area nor is a known roost tree within 150 feet of the Project area (DNR and USFWS 2020). Bald Eagles The bald eagle (Haliaeetus leucocephalus) is protected by the Bald and Golden Eagle Protection Act and the Migratory Bird Treaty Act. Both of these acts protect bald eagles from a variety of harmful actions and impacts. USFWS, the federal agency with jurisdiction over these acts, manages bald eagles in accordance with the National Bald Eagle Management Guidelines. There are no known eagle nests within the Project area. There is a known bald eagle nest approximately 1 mile southeast of the Project area, located on private property (DNR NHIS License Agreement 1022).

page 18

Minnesota Department of Natural Resources Special Status Species There are no known occurrences of DNR-listed endangered or threatened species, or species of special concern within the Project area. There are four documented occurrences of DNR-listed endangered or threatened species, or species of special concern within 1 mile of the Project area (DNR NHIS License Agreement 1022; see Attachment C). Species that occur within 1 mile of the Project area are listed in Table 7. Table 7. DNR-Listed Species within 1 mile of the Project Area

c. Discuss how the identified fish, wildlife, plant communities, rare features and ecosystems may be

affected by the project. Include a discussion on introduction and spread of invasive species from the project construction and operation. Separately discuss effects to known threatened and endangered species. Fish and Wildlife Fish and wildlife that reside within the Project area may be temporarily displaced to adjacent habitats during construction. Invasive Species Invasive species are nonnative species that can cause economic or environmental harm and could threaten natural resources. These species often spread rapidly in open corridors and can form large, dense single-species stands that reduce plant diversity. Ground disturbance and associated vegetation removal, along with construction equipment used in the water, may allow for the introduction of invasive species to the Project area. Wild Rice Lake of the Woods is designated a wild rice lake by DNR. Impacts on wild rice could occur as a result of the Project through excavation within Lake of the Woods substrate materials. Federally Listed Endangered and Threatened Species No documented NLEB hibernacula and/or roost trees are within the Project area. Additionally, tree clearing is not anticipated as part of the Project. Therefore, no impacts on NLEB are anticipated.

page 19

Because of the urban nature of the Project area and a lack of suitable habitat, no impacts on Canada lynx are anticipated as a result of the Project. Bald Eagles The Bald and Golden Eagle Protection Act prohibits the “taking” of bald eagles, which includes actions to pursue, shoot, shoot at, poison, wound, kill, capture, trap, collect, destroy, molest, or disturb a bald eagle (50 CFR §22.3). Additionally, taking includes the disturbance of bald eagles that interferes with breeding, feeding, or sheltering behavior or results in injury. Incidental taking includes human-caused alteration initiated around an active or previously active nest site that may result in agitation of an eagle to a degree that injures or substantially interferes with normal breeding, feeding, or sheltering habits and causes, or is likely to cause, a loss of productivity or nest abandonment (USFWS 2020). The Project would not result in the destruction or removal of a bald eagle nest. Construction activities associated with the Project would not occur within 700 feet of a bald eagle nest. Minnesota Department of Natural Resources Special Status Species No impacts on species identified in Table 7 in EAW Item 13.b. are anticipated as a result of the Project. Construction activities associated with the Project would be unlikely to affect populations of these species because of the lack of suitable habitat in the Project area.

d. Identify measures that will be taken to avoid, minimize, or mitigate adverse effects to fish, wildlife, plant communities, and sensitive ecological resources. Work within the boundaries of Lake of the Woods would occur outside of fish spawning timeframes as defined by the DNR Public Waters Work Permit. Following construction, the area would be restored to open water habitat, allowing the majority of fish and wildlife to return to the Project area. The Project would follow construction BMPs to control and prevent the spread of both terrestrial and aquatic invasive species. BMPs such as requiring vehicles to be clean prior to arriving to the Project area, equipment washing, draining all water from equipment prior to arrival onsite, minimizing soil disturbance to only areas necessary for construction activities, and stabilizing disturbed soils with materials that are free of invasive plant seed or materials would be implemented during construction. Wild Rice Coordination with DNR would occur prior to construction to identify potential impacts on wild rice, as well as mitigation and avoidance opportunities for potential impacts on wild rice.

14. Historic properties:

Describe any historic structures, archeological sites, and/or traditional cultural properties on or in close proximity to the site. Include: 1) historic designations, 2) known artifact areas, and 3) architectural features. Attach letter received from the State Historic Preservation Office (SHPO). Discuss any anticipated effects to historic properties during project construction and operation. Identify measures that will be taken to avoid, minimize, or mitigate adverse effects to historic properties.

page 20

A letter and electronic request to the Minnesota State Historic Preservation Office (SHPO) was made on September 17 and 29, 2020, respectively. The SHPO provided lists of 17 historic records and three recorded archaeological sites near the Project area. No records were found for sites within the Project area (see Attachment D for the letter to SHPO). Several records were found for sites outside the Project area to the west and the southeast. Sites to the west are historical sites found within the city. Sites to the southeast are along the mouth and shore of the Warroad River and Lakeview Park. Based on the lack of known sites within the Project area and the potential impacts of the Project, impacts on historic properties from the construction and maintenance of the Project would not be expected.

15. Visual: Describe any scenic views or vistas on or near the project site. Describe any project related visual effects such as vapor plumes or glare from intense lights. Discuss the potential visual effects from the project. Identify any measures to avoid, minimize, or mitigate visual effects. There are no designated scenic views or vistas on or near the Project site. All construction activities would occur during permitted hours, and the use of any lighted equipment would be limited to creating safe construction conditions. The proposed Project would add features (docks and parking lots) to previously undeveloped areas. Conversion of agricultural lands and a wooded area to parking would change the visual character of the Project area. These changes could impact residents that live within the changed viewshied. In addition, the Project is intended to increase the boat use of the area, which would add another visual element compared to existing conditions. However, there are several docks along the Warroad River, and the addition of these elements would not be out of character for the city. The Project would also store dredged materials in a disposal site approved by the United States Army Corps of Engineers. Although there are currently spoils being stored on the site, the increase of spoil material would add another visual element to the area. Construction, operation, and maintenance of the Project would result in short- and long-term impacts on the visual resources in the Project area. However, these impacts would be local and not out of character with other waterfront development in the city.

16. Air:

a. Stationary source emissions - Describe the type, sources, quantities and compositions of any emissions from stationary sources such as boilers or exhaust stacks. Include any hazardous air pollutants, criteria pollutants, and any greenhouse gases. Discuss effects to air quality including any sensitive receptors, human health or applicable regulatory criteria. Include a discussion of any methods used assess the project’s effect on air quality and the results of that assessment. Identify pollution control equipment and other measures that will be taken to avoid, minimize, or mitigate adverse effects from stationary source emissions. The Project would not include any stationary sources of emissions and would not produce emissions of hazardous air pollutants, criteria pollutants, or any greenhouse gases.

page 21

b. Vehicle emissions - Describe the effect of the project’s traffic generation on air emissions.

Discuss the project’s vehicle-related emissions effect on air quality. Identify measures (e.g. traffic operational improvements, diesel idling minimization plan) that will be taken to minimize or mitigate vehicle-related emissions. During construction, short-term increases in localized carbon monoxide levels and other vehicle-related emissions from construction equipment and worker transportation vehicles are anticipated. The magnitude of the construction emissions would be heavily influenced by weather conditions and the specific construction activity occurring. Air quality impacts as a result of exhaust emissions from primarily diesel equipment would vary according to the phase of construction but would be minimal and temporary. To minimize impacts, contractors would be required to maintain equipment properly, including using any emissions controls, as specified by the manufacturer. Air quality mitigation measures are not proposed. As discussed in EAW Item 18, the traffic-related impacts as a result of Project operation are anticipated to be minor, as are the impacts from increased boat traffic associated with the new boat slips.

c. Dust and odors - Describe sources, characteristics, duration, quantities, and intensity of dust and odors generated during project construction and operation. (Fugitive dust may be discussed under item 16a). Discuss the effect of dust and odors in the vicinity of the project including nearby sensitive receptors and quality of life. Identify measures that will be taken to minimize or mitigate the effects of dust and odors. In addition to minimal and temporary emissions from construction equipment, localized, short-term air quality impacts from fugitive dust are anticipated due to travel on unpaved roads and the excavation associated with the Project. Fugitive dust is considered particulate matter under air quality regulations. The concentrations of fugitive dust that is fine particulate matter (PM less than 2.5 microns or PM2.5) is generally small, or approximately 3 to 10 percent of total particulate matter (USEPA 1995, 1998). Because fine particulate matter has the potential to travel further into the lungs, it is of greater concern than larger particle size ranges. As such, the Project would mitigate dust issues from construction traffic by using standard construction practices such as watering of exposed surfaces, covering of disturbed areas, and reduced speed limits on site. Dust mitigation practices would be outlined in the Project Construction SWPPP. During Project operation, insignificant emissions would be generated by operations associated with periodic inspection and maintenance activities, traffic to the parking lots, and increased boat activity associated with the new boat slips.

17. Noise

Describe sources, characteristics, duration, quantities, and intensity of noise generated during project construction and operation. Discuss the effect of noise in the vicinity of the project including 1) existing noise levels/sources in the area, 2) nearby sensitive receptors, 3) conformance to state noise standards, and 4) quality of life. Identify measures that will be taken to minimize or mitigate the effects of noise. 1) Existing noise levels/sources in the area:

page 22

The Project site is in a recreational and residential part of Warroad in Roseau County. The Project area is bounded to the north by open park land and wetlands, to the east by open and recreational park land and Lake of the Woods, to the south by open and recreational park land and single-family residential, and to the west by a seasonal campground and single-family residential. Lightly traveled roads are located throughout and around the Project area, including 4th Avenue NE. Typical sources of noise in this area include traffic along adjacent roadways and ambient noises that would be typical of both lake and park recreation as well as campground and nearby residential inhabitation. As of 2012, the average annual daily traffic was approximately 550 vehicles per day for 4th Avenue NE (Minnesota Department of Transportation 2020). Traffic counts were unavailable for the less-traveled roadways throughout the Project area accessing the seasonal campground. 2) Nearby sensitive receptors: The Project area is currently in an open and recreational park land area with a seasonal campground. Single-family homes are adjacent to the site to the west and south. 3) Conformance to state noise standards: Minnesota Rules, part 7030.0040 establishes noise standards to “describe the limiting levels of sound established on the basis of present knowledge for the preservation of public health and welfare.” Administered by MPCA (2019), the primary noise limits are set by noise area classifications (NACs) based on the land use at the location of the person who hears the noise. The noise limits are based on the sound level in A-weighted decibels (dBA) over 10 percent (L10), or 6 minutes, and 50 percent (L50), or 30 minutes, of an hour. Table 8 shows the MPCA’s daytime (7 a.m. to 10 p.m.) and nighttime (10 p.m. to 7 a.m.) limits in dBA for the three NACs. NACs are defined in Minnesota Rules part 7030.0050 as follows: NAC 1 includes residences, hotels, medical and other health services, educational services, and religious services; NAC 2 includes automobile parking, retail trade (including restaurants and bars), recreational activities (except designated camping and picnicking areas) and parks; and NAC 3 includes transportation, highway and street right-of-way, fishing activities and related activities. There is a fourth NAC defined in Minnesota Rules part 7030.0040 that includes undeveloped and unused land area, noncommercial forest development, water areas, vacant floor area and under construction. NAC 4 does not have noise limits assigned to it.

Table 8. MPCA Daytime and Nighttime Noise Limits

Noise Area Classification

The Project would contribute to existing noise in the area during construction and operation. Construction noise would be temporary and intermittent and would occur over the estimated construction timeframe of 7 months. Residences near the Project site may experience elevated noise levels at various times during construction compared to existing noise levels. These construction noise levels would be consistent with those of a typical construction site, including use of earthmoving equipment, large machinery, trucks, hydraulic tools, and other equipment necessary for excavating a navigable channel out into Lake of the Woods from the existing north and south harbors and building approximately 112 boat slips in the north harbor and approximately 68 boat slips in the south harbor. Construction of two parking lots and a stormwater pond would require heavy equipment, such as skid steers, backhoes, trucks, and other excavating equipment. Construction at the

page 23

Taylor Road bridge would include installing sheet pile and stop logs. Construction noise would be mitigated through the use of mufflers and other sound dampening devices on construction equipment and vehicles. The City of Warroad anticipates that construction activities would typically occur between the hours of 7 a.m. and 7 p.m. Monday through Saturday. During operation of the Project, the primary source of noise would be from increased boat traffic as well as use of the parking lots to access the new boat slips. Noise levels would be consistent with those currently experienced in the Project area throughout the day and, as would be expected from a recreational boating facility, lower during non-daylight hours. All routine maintenance would be performed during daytime hours. No mitigation measures are proposed for the operational phase of the Project because operational noise levels are not predicted to exceed the state noise limits. 4) Quality of life: Noise impacts from the Project are not expected to exceed state noise limits. The areas surrounding the Project site are not anticipated to be significantly impacted by noise because noise levels would be primarily from boats operating in a no wake zone in the north and south harbors and would be consistent with the recreational and seasonal campground use in the Project area.

18. Transportation a. Describe traffic-related aspects of project construction and operation. Include: 1) existing and

proposed additional parking spaces, 2) estimated total average daily traffic generated, 3) estimated maximum peak hour traffic generated and time of occurrence, 4) indicate source of trip generation rates used in the estimates, and 5) availability of transit and/or other alternative transportation modes. Traffic-related impacts as a result of the Project are anticipated to be minor and would occur on a temporary basis during excavation and hauling of dredged material. Proposed daily traffic generation during construction is approximately 30 trips per day, or approximately 5 vehicles per hour over a 10-hour day. Construction could start as early as 2021 with completion in 2022. Access to the site would be from either 1st Avenue NE or Mackenzie Street NE. This would include construction vehicles entering and existing the site. The nature of the construction activities and the use of specialized equipment required during construction would not allow for the use of alternative transportation modes. All construction work would be performed during hours specified by permits and local requirements. Vehicles and equipment would cease entering and exiting the site upon completion of construction.

b. Discuss the effect on traffic congestion on affected roads and describe any traffic improvements necessary. The analysis must discuss the project’s impact on the regional transportation system. If the peak hour traffic generated exceeds 250 vehicles or the total daily trips exceeds 2,500, a traffic impact study must be prepared as part of the EAW. Use the format and procedures described in the Minnesota Department of Transportation’s Access Management Manual, Chapter 5 (available at: http://www.dot.state.mn.us/accessmanagement/resources.html) or a similar local guidance,

page 24

As identified in EAW Item 18.a, the Project is anticipated to generate 30 daily trips during construction, which is below the daily trip threshold for a traffic impact study as defined by the EAW. The existing traffic levels on 1st Avenue NE and Mackenzie Street NE near the Project area are low. Given the addition of 30 daily trips, it is anticipated that the roadways would have adequate capacity to accommodate the estimated increase in traffic during the 7-month period of construction.

c. Identify measures that will be taken to minimize or mitigate project related transportation effects. Upon completion of construction, there would be minimal traffic increases anticipated related to access to boat slips. The Project-related transportation impacts would be minimal and are not expected to adversely affect the transportation system; therefore, no minimization or mitigation measures would be necessary.

19. Cumulative potential effects: (Preparers can leave this item blank if cumulative potential effects are addressed under the applicable EAW Items) a. Describe the geographic scales and timeframes of the project related environmental effects that

could combine with other environmental effects resulting in cumulative potential effects. The area considered for cumulative potential effects covers the eastern portion of the city—east of 1st Avenue NE to Lake of the Woods and areas surrounding the Project site. The timeframe used was the length of construction, when most impacts would occur.

b. Describe any reasonably foreseeable future projects (for which a basis of expectation has been laid) that may interact with environmental effects of the proposed project within the geographic scales and timeframes identified above. There are no other known reasonably foreseeable future projects that may interact with the environmental effects of the proposed Project.

c. Discuss the nature of the cumulative potential effects and summarize any other available information relevant to determining whether there is potential for significant environmental effects due to these cumulative effects. Any cumulative potential effects, if present, would likely occur during the construction phase of the Project. A search and review of the City of Warroad’s website and the Chamber of Commerce website did not identify any reasonably foreseeable future actions in or near the proposed Project area.

20. Other potential environmental effects: If the project may cause any additional environmental effects not addressed by items 1 to 19, describe the effects here, discuss the how the environment will be affected, and identify measures that will be taken to minimize and mitigate these effects. No additional environmental effects not previously described are expected from the construction and operation of the Project.

SILT FENCE INSTALLATION

1. THE GEOTEXTILE AT THE BOTTOM OF THE FENCE SHALL BE BURIED IN A "J" CONFIGURATION TO A MINIMUM DEPTH OF 6 INCHES IN A TRENCH SO THAT NO FLOW CAN PASS UNDER THE

FENCE. WIRE SUPPORT FENCE, IF USED, SHALL BE BURIED A MINIMUM OF 2 INCHES. THE TRENCH ON THE UPSTREAM SIDE OF THE SILT FENCE SHALL BE BACKFILLED AND THE SOILCOMPACTED OVER THE GEOTEXTILE.

2. SILT FENCE FABRICS SHALL BE SPLICED TOGETHER ONLY AT SUPPORT POSTS WITH A MINIMUM OF 18 INCHES OF OVERLAP AND IN SUCH A MANNER TO PREVENT SILT FROM PASSING

BETWEEN THE TWO ENDS. AT THE TIME OF INSTALLATION, THE FABRIC OR FENCE WILL BE REJECTED IF IT HAS ANY DEFECTS, DETERIORATION, OR OTHER DAMAGE INCURRED DURING

MANUFACTURE, TRANSPORTATION, STORAGE, OR INSTALLATION.

3. POSTS SHALL BE SPACED 4 FEET APART AND DRIVEN OR PLACED A MINIMUM OF 24 INCHES INTO THE GROUND. DEPTH SHALL BE INCREASED TO 24 INCHES IF FENCE IS PLACED ON A SLOPE3:1 OR GREATER. GEOTEXTILES SHALL BE ATTACHED TO POSTS BY STAPLES, WIRE, OR NAILS, OR IN ACCORDANCE WITH THE MANUFACTURER'S RECOMMENDATIONS. WIRE STAPLES SHALLBE A NO. 17 GAUGE MINIMUM AND SHALL HAVE A MINIMUM OF 0.75 IN WIDE CROWN AND 0.5 IN LONG LEGS. STAPLES SHALL BE EVENLY PLACED WITH AT LEAST 4 PER POST. NAILS SHALL BE A

MINIMUM OF 14 GAUGE, 1 INCH LONG, WITH 0.75 BUTTON HEADS. NAILS SHALL BE EVENLY SPACED WITH 4 PER POST.

4. SILT FENCES SHALL BE CONTINUOUS AND TRANSVERSE TO THE FLOW. THE SILT FENCE SHALL FOLLOW THE CONTOURS OF THE SITE AS CLOSELY AS POSSIBLE. THE FENCE SHALL ALSO BEPLACED SUCH THAT THE WATER CANNOT FLOW AROUND THE END OF THE FENCE.

1. THE POINT PARK HARBOR PROJECT CONSISTS OF THECONSTRUCTION AND RE-EXCAVTION OF APPROXIMATELY1 MILE OF CHANNEL AS WELL AS TWO PARKING LOTS INROSEAU COUNTY, MN. THE RECEIVING WATER IS THELAKE OF THE WOODS.

2. THE PROJECT IS LOCATED WITHIN 1 MILE OF THE LAKE OFTHE WOODS, WHICH IS IMPAIRED FOR MERCURY. THEREARE NO SURFACE WATERS IMPAIRED FOR PHOSPHORUS,TURBIDITY, TSS, DISSOLVED OXYGEN, OR AQUATIC BIOTAWITHIN 1 MILE OF THE PROJECT.

3. DURING CONSTRUCTION

ALL EXPOSED SOIL AREAS MUST BE STABILIZED AS SOONAS POSSIBLE TO LIMIT SOIL EROSION BUT IN NO CASELATER THAN SEVEN DAYS AFTER THE CONSTRUCTIONACTIVITY IN THAT PORTION OF THE SITE HASTEMPORARILY OR PERMANENTLY CEASED.

4. POST-CONSTRUCTION

THE WATER QUALITY VOLUME THAT MUST BE TREATED BYTHE PROJECT'S PERMANENT STORMWATERMANAGEMENT SYSTEM SHALL BE ONE (1) INCH OFRUNOFF FROM THE NEW IMPERVIOUS SURFACESCREATED BY THE PROJECT. WHERE SITE CONDITIONSALLOW, AT LEAST 1 INCH OF THE WATER QUALITYVOLUME MUST BE INFILTRATED.

5. CHAIN OF RESPONSIBILITY

THE GENERAL CONTRACTOR IS RESPONSIBLE FORDEVELOPING A CHAIN OF RESPONSIBILITY WITH THE SITEOPERATORS AND MUST OVERSEE IMPLEMENTATION OFTHE SWPPP, INCLUDING THE INSTALLATION,MAINTENANCE, AND INSPECTION OF EROSION PREVENTION AND SEDIMENT CONTROL BESTMANAGEMENT PRACTICES (BMPs). THE SWPPP MUST BEIMPLEMENTED AND STAY IN EFFECT UNTIL THE PROJECTIS COMPLETE, THE ENTIRE SITE HAS ACHIEVED FINALSTABILIZATION, AND A NOTICE OF TERMINATION HASBEEN SUBMITTED TO THE MPCA.

6. PRECONSTRUCTION PRACTICES

BEFORE LAND-DISTURBING ACTIVITIES OCCUR, THEREARE SEVERAL PRINCIPLES THAT CAN BE FOLLOWED TOHELP CONTROL EROSION AND MITIGATE SEDIMENTRUNOFF. THEY INCLUDE:

· DELINEATE AREAS NOT TO BE DISTURBED PRIOR TOCONSTRUCTION

· INSTALL DOWNSLOPE AND SIDESLOPE PERIMETERCONTROLS

· DO NOT DISTURB AN AREA UNTIL IT IS NECESSARY FORCONSTRUCTION TO PROCEED

· SCHEDULE ACTIVITIES TO LIMIT IMPACT FROM SEASONALCLIMATE CHANGES OR WEATHER EVENTS.

· PLAN TO COVER OR STABILIZE DISTURBED AREAS ASSOON AS POSSIBLE.

7. SOIL STABILIZATION

ALL EXPOSED AREAS, INCLUDING STOCKPILES, MUST BESTABILIZED. STABILIZATION MUST BE INITIATEDIMMEDIATELY TO LIMIT SOIL EROSION WHENCONSTRUCTION ACTIVITY HAS PERMANENTLY ORTEMPORARILY CEASED ON ANY PORTION OF THE SITEAND WILL NOT RESUME FOR A PERIOD EXCEEDING (7)SEVEN CALENDAR DAYS. STABILIZATION MUST BECOMPLETED NO LATER THAN (7) SEVEN CALENDAR DAYSAFTER CONSTRUCTION HAS CEASED.

THE LAST 200 LINEAL FEET OF DRAINAGE DITCH ORCHANNEL MUST BE STABILIZED WITHIN 24 HOURS OFCONNECTION TO THE RED LAKE RIVER.

TEMPORARY STOCKPILES WITHOUT SIGNIFICANT CLAY ORORGANIC COMPONENTS AND THE CONSTRUCTED BASECOMPONENTS OF ROADWAYS ARE EXEMPT FROM THISREQUIREMENT.

9. EROSION CONTROL BLANKET (ECB)

EROSION CONTROL BLANKETS FUNCTION BY PROVIDINGGROUND COVER THAT REDUCES EROSIVE ACTION.EROSION CONTROL BLANKETS MAY BE USED INCONJUNCTION WITH OTHER VELOCITY REDUCING BMPs.EROSION CONTROL BLANKET APPLICATIONS INCLUDESLOPE AND DITCH PROTECTION.

7. SEEDING

IN AREAS WHERE CONSTRUCTION ACTIVITIES WILL BE ABSENT FORMORE THAN (7) SEVEN DAYS, TEMPORARY SEEDING SHOULD BEINCORPORATED TO PROVIDE TEMPORARY STABILIZATION. SEEDINGSHOULD ALWAYS BE ACCOMPANIED BY MULCH, EROSION CONTROLBLANKET, OR TACKIFYING TO PROTECT THE SEED AND SOIL FROMEROSION DURING THE GERMINATION AND GROWTH PROCESS. IFSEEDING CANNOT BE ACCOMPLISHED DUE TO SEASONAL CONSTRAINTS,TEMPORARY STABILIZATION SUCH AS MULCH OR TACKIFIER MUST BEUSED AND MAINTAINED UNTIL THE ACCOMPANYING SEED ISESTABLISHED.

8. CULVERT INLET AND OUTLET PROTECTION

CULVERT INLET PROTECTION SHOULD BE INSTALLED ON THE UPSTREAMEND OF A CULVERT TO PREVENT SEDIMENT FROM TRAVELING THROUGHTHE SYSTEM. CULVERT INLET PROTECTION TYPICALLY CONSISTS OFSEDIMENT CONTROL LOGS. CULVERT OUTLET PROTECTION TYPICALLYCONSISTS OF RIPRAP OR EROSION CONTROL BLANKET. CULVERTOUTLETS MUST BE PROVIDED WITH TEMPORARY OR PERMANENTENERGY DISSIPATION WITHIN 24 HOURS OF CONNECTING TO A SURFACEWATER. CULVERT PROTECTION BMPs SHOULD SURROUND THECULVERT ENTRANCE/EXIT COMPLETELY.

9. CONCRETE AND OTHER WASHOUT WASTE

EFFECTIVE CONTAINMENT MUST BE PROVIDED FOR ALL LIQUID ANDSOLID WASTES GENERATED BY WASHOUT OPERATIONS (CONCRETE,STUCCO, PAINT, FORM RELEASE OILS, CURING COMPOUNDS, ANDOTHER CONSTRUCTION MATERIALS) RELATED TO PROJECTCONSTRUCTION. LIQUID AND SOLID WASHOUT WASTES MUST NOTCONTACT THE GROUND, AND THE CONTAINMENT MUST BE DESIGNEDSO THAT IT DOES NOT RESULT IN RUNOFF FROM THE WASHOUTOPERATIONS OR AREAS. LIQUID AND SOLID WASTES MUST BE DISPOSEDOF PROPERLY AND IN COMPLIANCE WITH APPLICABLE FEDERAL, STATE,AND LOCAL REQUIREMENTS. A SIGN MUST BE INSTALLED ADJACENT TOEACH WASHOUT FACILITY THAT REQUIRES SITE PERSONNEL TO USETHE PROPER FACILITIES FOR DISPOSAL OF CONCRETE AND OTHERWASHOUT WASTES.

10. INSPECTIONS

INSPECTIONS OF TEMPORARY EROSION AND SEDIMENT CONTROLSMUST BE CONDUCTED BY A TRAINED PERSON AT LEAST ONCE EVERYSEVEN (7) DAYS, AND WITHIN 24 HOURS AFTER A RAINFALL EVENTGREATER THAN 0.5 INCHES IN 24 HOURS.

11. MAINTENANCEALL BMPs MUST BE REPAIRED, REPLACED, OR SUPPLEMENTED WITHFUNCTIONAL BMPs. MAINTENANCE PRACTICES INCLUDE:

· PERIMETER CONTROL DEVICES (SILT FENCE) MUST BE REPAIRED,REPLACED, OR SUPPLEMENTED WHEN THEY BECOME NON-FUNCTIONALOR ACCUMULATED SEDIMENT REACHES 1/2 THE HEIGHT OF THE DEVICE.REPAIRS MUST BE MADE BY THE END OF THE NEXT BUSINESS DAYAFTER DISCOVERY.

· SEDIMENTATION BASINS MUST BE DRAINED AND SEDIMENT REMOVEDWHEN THE DEPTH OF SEDIMENT COLLECTED REACHES 1/2 OF THESTORAGE VOLUME. DRAINAGE AND REMOVAL MUST BE COMPLETEDWITHIN 72 HOURS OF DISCOVERY.

· SURFACE WATERS MUST BE INSPECTED FOR EVIDENCE OF EROSIONAND SEDIMENT DEPOSITION. ALL DELTAS AND SEDIMENT DEPOSITED INSURFACE WATERS AND DRAINAGE SYSTEMS MUST BE REMOVED, ANDAREAS WHERE SEDIMENT REMOVAL RESULTS IN EXPOSED SOIL MUSTBE RESTABILIZED. THE REMOVED AND STABILIZATION MUST TAKE PLACEWITHIN SEVEN (7) DAYS OF DISCOVERY.

12. FINAL STABILIZATION

ALL TURF AREAS MUST BE MAINTAINED UNTIL THE SITE HASUNDERGONE FINAL STABILIZATION. MAINTENANCE INCLUDESWATERING, RE-SEEDING, AND RE-APPLYING STABILIZATION MEASURES.FINAL STABILIZATION MEANS THAT:

· ALL SOIL DISTURBING ACTIVITIES HAVE BEEN COMPLETED AND ALLSOILS ARE STABILIZED BY A UNIFORM PERENNIAL VEGETATIVE COVERWITH A DENSITY OF 70 PERCENT OF ITS EXPECTED FINAL GROWTHDENSITY.

· ALL SEDIMENT HAS BEEN REMOVED FROM CONVEYANCE SYSTEMS, ANDDITCHES AND DRAINAGEWAYS ARE STABILIZED WITH PERMANENTCOVER.

· ALL TEMPORARY SYNTHETIC AND STRUCTURAL EROSION PREVENTIONAND SEDIMENT CONTROL BMPs HAVE BEEN REMOVED. BMPs DESIGNEDTO DECOMPOSE ON SITE MAY BE LEFT IN PLACE.

13. NOTICE OF TERMINATION

A NOTICE OF TERMINATION MUST BE SUBMITTED TO THE MINNESOTAPOLLUTION CONTROL AGENCY WITHIN 30 DAYS AFTER FINALSTABILIZATION HAS BEEN ACHIEVED ON ALL PORTIONS OF THE SITE.

14. IMPLEMENTATION RESPONSIBILITIES

THE CONTRACTOR IS RESPONSIBLE FOR IMPLEMENTATION OF THESWPPP AND THE INSTALLATION, INSPECTION, AND MAINTENANCE OFTHE EROSION AND SEDIMENT CONTROL BMPs BEFORE AND DURINGCONSTRUCTION. THE MINNESOTA DNR/CITY OF WARROAD ARERESPONSIBLE FOR THE LONG-TERM OPERATION AND MAINTENANCE OFTHE PERMANENT STORMWATER MANAGEMENT SYSTEM.

In Reply Refer To: Consultation Code: 03E19000-2021-SLI-0084 Event Code: 03E19000-2021-E-00270 Project Name: Thief River Falls Oxbow Subject: List of threatened and endangered species that may occur in your proposed project

location, and/or may be affected by your proposed project

To Whom It May Concern:

The attached species list identifies any federally threatened, endangered, proposed and candidate species that may occur within the action area the area that is likely to be affected by your proposed project. The list also includes any designated and proposed critical habitat that overlaps with the action area. This list is provided to you as the initial step of the consultation process required under section 7(c) of the Endangered Species Act, also referred to as Section 7 Consultation.

Section 7 of the Endangered Species Act of 1973 requires that actions authorized, funded, or carried out by Federal agencies not jeopardize federally threatened or endangered species or adversely modify designated critical habitat. To fulfill this mandate, Federal agencies (or their designated non-federal representatives) must consult with the Service if they determine their project may affect listed species or critical habitat. Agencies must confer under section 7(a)(4) if any proposed action is likely to jeopardize species proposed for listing as endangered or threatened or likely to adversely modify any proposed critical habitat.

Under 50 CFR 402.12(e) (the regulations that implement Section 7 of the Endangered Species Act) the accuracy of this species list should be verified after 90 days. This verification can be completed formally or informally. You may verify the list by visiting the ECOS-IPaC website http://ecos.fws.gov/ipac/ at regular intervals during project planning and implementation and completing the same process you used to receive the attached list. As an alternative, you may contact this Ecological Services Field Office for updates.

Please use the species list provided and visit the U.S. Fish and Wildlife Service's Region 3 Section 7 Technical Assistance website at - http://www.fws.gov/midwest/endangered/section7/ s7process/index.html. This website contains step-by-step instructions that will help you

determine if your project will have an adverse effect on listed species or critical habitat and will help lead you through the Section 7 process.

For all wind energy projects and projects that include installing towers that use guy wires or are over 200 feet in height, please contact this field office directly for assistance, even if no federally listed plants, animals or critical habitat are present within the action area.

Although no longer protected under the Endangered Species Act, be aware that bald eagles (Haliaeetus leucocephalus) are protected under the Bald and Golden Eagle Protection Act (16 U.S.C. 668 et seq.) and Migratory Bird Treaty Act (16 U.S.C. 703 et seq), as are golden eagles (Aquila chrysaetos). Projects affecting these species may require measures to avoid harming eagles or may require a permit. If your project is near a bald eagle nest or winter roost area, see our Eagle Permits website at http://www.fws.gov/midwest/midwestbird/EaglePermits/index.html. The information available at this website will help you determine if you can avoid impacting eagles or if a permit may be necessary.

We appreciate your concern for threatened and endangered species. Please include the Consultation Tracking Number in the header of this letter with any request for consultation or correspondence about your project that you submit to our office.

Project SummaryConsultation Code: 03E19000-2021-SLI-0084

Event Code: 03E19000-2021-E-00270

Project Name: Thief River Falls Oxbow

Project Type: DREDGE / EXCAVATION

Project Description: The City of Thief River Falls Minnesota is proposing to restore an oxbow from the Red Lake River located in the SE ¼ of Section 33 (T154, R43W) of North Township within the city limits of Thief River Falls. The Project would include removing lime sludge and sediment in the Eastern portion of the existing oxbow and installing a sediment removal system to reduce the amount of sediment contained in stormwater entering the basin. Portions of the lime sludge and sediment existing in the oxbow would be removed in the restoration area. The data collected the sediment thickness survey, would be carefully removed with an excavator, making sure to leave native river bottom substrate soils in place. The shape of the oxbow with a tree covered peninsula dividing it into two regions resulted in the decision to excavate approximately 17,000 cubic yards of sediment. This would include only removing sediment on the Eastern portion of the oxbow to limit tree removal. During excavation, it will be important for contractors and project managers to follow Best Management Practices for preventing the spread of invasive species. The site would then be restored with native vegetation.

Endangered Species Act SpeciesThere is a total of 1 threatened, endangered, or candidate species on this species list.

Species on this list should be considered in an effects analysis for your project and could include species that exist in another geographic area. For example, certain fish may appear on the species list because a project could affect downstream species.

IPaC does not display listed species or critical habitats under the sole jurisdiction of NOAA Fisheries , as USFWS does not have the authority to speak on behalf of NOAA and the Department of Commerce.

See the "Critical habitats" section below for those critical habitats that lie wholly or partially within your project area under this office's jurisdiction. Please contact the designated FWS office if you have questions.

NOAA Fisheries, also known as the National Marine Fisheries Service (NMFS), is an office of the National Oceanic and Atmospheric Administration within the Department of Commerce.

activities to avoid or minimize impacts to birds. Please make sure you read and understand the FAQ “Proper Interpretation and Use of Your Migratory Bird Report” before using or attempting to interpret this report.

Probability of Presence ( )

Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your project overlaps during a particular week of the year. (A year is represented as 12 4-week months.) A taller bar indicates a higher probability of species presence. The survey effort (see below) can be used to establish a level of confidence in the presence score. One can have higher confidence in the presence score if the corresponding survey effort is also high.

How is the probability of presence score calculated? The calculation is done in three steps:

The probability of presence for each week is calculated as the number of survey events in the week where the species was detected divided by the total number of survey events for that week. For example, if in week 12 there were 20 survey events and the Spotted Towhee was found in 5 of them, the probability of presence of the Spotted Towhee in week 12 is 0.25.To properly present the pattern of presence across the year, the relative probability of presence is calculated. This is the probability of presence divided by the maximum probability of presence across all weeks. For example, imagine the probability of presence in week 20 for the Spotted Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the maximum of any week of the year. The relative probability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2.The relative probability of presence calculated in the previous step undergoes a statistical conversion so that all possible values fall between 0 and 10, inclusive. This is the probability of presence score.

Breeding Season ( )Yellow bars denote a very liberal estimate of the time-frame inside which the bird breeds across its entire range. If there are no yellow bars shown for a bird, it does not breed in your project area.

Survey Effort ( )Vertical black lines superimposed on probability of presence bars indicate the number of surveys performed for that species in the 10km grid cell(s) your project area overlaps. The number of surveys is expressed as a range, for example, 33 to 64 surveys.

No Data ( )A week is marked as having no data if there were no survey events for that week.

Survey TimeframeSurveys from only the last 10 years are used in order to ensure delivery of currently relevant information. The exception to this is areas off the Atlantic coast, where bird returns are based on all years of available data, since data in these areas is currently much more sparse.

Migratory Birds FAQTell me more about conservation measures I can implement to avoid or minimize impacts to migratory birds. Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all birds at any location year round. Implementation of these measures is particularly important when birds are most likely to occur in the project area. When birds may be breeding in the area, identifying the locations of any active nests and avoiding their destruction is a very helpful impact minimization measure. To see when birds are most likely to occur and be breeding in your project area, view the Probability of Presence Summary. Additional measures and/or permits may be advisable depending on the type of activity you are conducting and the type of infrastructure or bird species present on your project site.

What does IPaC use to generate the migratory birds potentially occurring in my specified location? The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC) and other species that may warrant special attention in your project location.

The migratory bird list generated for your project is derived from data provided by the Avian Knowledge Network (AKN). The AKN data is based on a growing collection of survey, banding, and citizen science datasets and is queried and filtered to return a list of those birds reported as occurring in the 10km grid cell(s) which your project intersects, and that have been identified as warranting special attention because they are a BCC species in that area, an eagle (Eagle Act requirements may apply), or a species that has a particular vulnerability to offshore activities or development.

Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area. It is not representative of all birds that may occur in your project area. To get a list of all birds potentially present in your project area, please visit the AKN Phenology Tool.

What does IPaC use to generate the probability of presence graphs for the migratory birds potentially occurring in my specified location? The probability of presence graphs associated with your migratory bird list are based on data provided by the Avian Knowledge Network (AKN). This data is derived from a growing collection of survey, banding, and citizen science datasets .

Probability of presence data is continuously being updated as new and better information becomes available. To learn more about how the probability of presence graphs are produced and how to interpret them, go the Probability of Presence Summary and then click on the "Tell me about these graphs" link.

How do I know if a bird is breeding, wintering, migrating or present year-round in my project area? To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering, migrating or year-round), you may refer to the following resources: The Cornell Lab of Ornithology All About Birds Bird Guide, or (if you are unsuccessful in locating the bird of

interest there), the Cornell Lab of Ornithology Neotropical Birds guide. If a bird on your migratory bird species list has a breeding season associated with it, if that bird does occur in your project area, there may be nests present at some point within the timeframe specified. If "Breeds elsewhere" is indicated, then the bird likely does not breed in your project area.

What are the levels of concern for migratory birds? Migratory birds delivered through IPaC fall into the following distinct categories of concern:

"BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their range anywhere within the USA (including Hawaii, the Pacific Islands, Puerto Rico, and the Virgin Islands);"BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in the continental USA; and"Non-BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either because of the Eagle Act requirements (for eagles) or (for non-eagles) potential susceptibilities in offshore areas from certain types of development or activities (e.g. offshore energy development or longline fishing).

Although it is important to try to avoid and minimize impacts to all birds, efforts should be made, in particular, to avoid and minimize impacts to the birds on this list, especially eagles and BCC species of rangewide concern. For more information on conservation measures you can implement to help avoid and minimize migratory bird impacts and requirements for eagles, please see the FAQs for these topics.

Details about birds that are potentially affected by offshore projects For additional details about the relative occurrence and abundance of both individual bird species and groups of bird species within your project area off the Atlantic Coast, please visit the Northeast Ocean Data Portal. The Portal also offers data and information about other taxa besides birds that may be helpful to you in your project review. Alternately, you may download the bird model results files underlying the portal maps through the NOAA NCCOS Integrative Statistical Modeling and Predictive Mapping of Marine Bird Distributions and Abundance on the Atlantic Outer Continental Shelf project webpage.

Bird tracking data can also provide additional details about occurrence and habitat use throughout the year, including migration. Models relying on survey data may not include this information. For additional information on marine bird tracking data, see the Diving Bird Study and the nanotag studies or contact Caleb Spiegel or Pam Loring.

What if I have eagles on my list? If your project has the potential to disturb or kill eagles, you may need to obtain a permit to avoid violating the Eagle Act should such impacts occur.

Proper Interpretation and Use of Your Migratory Bird Report The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of priority concern. To learn more about how your list is generated, and see options for identifying what other birds may be in your project area, please see the FAQ “What does IPaC

use to generate the migratory birds potentially occurring in my specified location”. Please be aware this report provides the “probability of presence” of birds within the 10 km grid cell(s) that overlap your project; not your exact project footprint. On the graphs provided, please also look carefully at the survey effort (indicated by the black vertical bar) and for the existence of the “no data” indicator (a red horizontal bar). A high survey effort is the key component. If the survey effort is high, then the probability of presence score can be viewed as more dependable. In contrast, a low survey effort bar or no data bar means a lack of data and, therefore, a lack of certainty about presence of the species. This list is not perfect; it is simply a starting point for identifying what birds of concern have the potential to be in your project area, when they might be there, and if they might be breeding (which means nests might be present). The list helps you know what to look for to confirm presence, and helps guide you in knowing when to implement conservation measures to avoid or minimize potential impacts from your project activities, should presence be confirmed. To learn more about conservation measures, visit the FAQ “Tell me about conservation measures I can implement to avoid or minimize impacts to migratory birds” at the bottom of your migratory bird trust resources page.

Lisa Joyal Minnesota Department of Natural Resources Natural Heritage Information System 500 Lafayette Road St Paul, MN 55101 RE: Request for Concurrence of Review of Natural Heritage Database (NHIS) for Warroad Safe Harbor Project (Township 163,

Range 36W, Section 15, 21, 22, 28, 29)

Ms. Lisa Joyal,

HDR Engineering, Inc. (HDR) is assisting the City of Warroad in developing an Environmental Assessment Worksheet (EAW) for the Warroad Safe Harbor Project that would be located in Roseau County and Lake of the Woods County, Minnesota. The proposed project area is largely located in Township 163, Range 36W, Section 15, 21, 22, 28 and 29 (see attached figure). HDR has reviewed publically available data and prepared a preliminary Minnesota Department of Natural Resources (MnDNR) NHIS review using data obtained under HDR License Agreement 933. HDR requests your concurrence with the results of our preliminary database review as described below.

The preliminary data review showed that a Minnesota Biological Survey (MBS) Site of Moderate Biodiversity Significance is located approximately 0.5 miles southeast of the project area (see attached figure). In addition, Lake of the Woods is identified as a MnDNR Wild Rice Lake.

The MnDNR NHIS database search identified species listed in the table below within 1 mile of the proposed project boundary. None of the listed species are located directly within the proposed project boundary.

Table 1 - MN DNR Listed Species within 1 mile

Common Name

Scientific Name Preferred Habitat Status

Nuttall's Sunflower

Helianthus nuttallii ssp. rydbergii
