Part I.C.2 Stormwater Management Plan (SWMP – Contents: Site Map)

See the approved Overlot Grading & Erosion Control Plans for this site.

These plans are considered part of this SWMP and shall be kept at the site at

all times. Modifications to the erosion control plan may be necessary from

time to time based on site inspections. Any additions or deletions of erosion

control measures should be documented on the site copy of the Overlot

Grading & Erosion Control Plans.

C.4 BMP’s and Other Controls

Part I.B.3 Contents and Requirements – BMP’s for Stormwater Pollution Prevention

a) Erosion and Sediment Controls

1) Structural Practices for Erosion and Sediment Control

Use of filter fabric silt fencing at site perimeter locations and

throughout the site (before commencement of construction activities).

Silt fence shall also be located around dirt stockpiles.

Straw bale barriers to protect ditches, swales and inlets (immediately

after construction of each item).

Vehicle tracking control devices at construction traffic ingress/egress

points to prevent sediment tracking onto surrounding streets (before

commencement of construction activities).

Slope protection erosion control blankets shall be installed and staked

on 3:1 slopes as shown on the Overlot Grading & Erosion Control Plan

or as deemed appropriate by the site construction manager (installed

after completion of overlot grading operations).

All disturbed areas shall have crimped straw installed and shall be

reseeded. A recommended seed mix and application rate is included

below.

All slopes not covered with slope protection erosion control blankets

shall be roughed. Roughening shall be performed to follow the

contour of the slope, that is, the roughening shall be perpendicular to

surface runoff flow direction.

of 13

There is 1 permanent regional detention pond facility adjacent to the

project that includes water quality capture volume. The water quality

volume portion of the permanent pond shall not serve as temporary

sedimentation basins during and after site construction. The contractor

should be aware that the sedimentation basins are considered a last line

of defense and that the majority of sediment should be contained on

the site near the source of the erosion using the other structural

sediment control measures described in this report.

2) Non-structural Practices for Erosion and Sediment Control

Temporary or permanent seeding will be employed in all areas

disturbed by construction activities that will remain dormant for

greater than 60 days. Should excessive blowing of sediment become

apparent, then the contractor shall water the site for dust control.

Recommended Seed Mix:

Sandy Foothills

Drilled 30 lbs/ acre, Broadcast 35 lbs/ acre

15% Prairie Sandreed

25% Sideoats Grama

15% Blue Grama

20% Switch Grass

25% Little Bluestem

3) Materials Handling and Spill Prevention

Spill prevention and containment measures shall be used at storage,

and equipment fueling and servicing areas to prevent the pollution of

any state waters, including wetlands. All spills shall be cleaned up

immediately after discovery, or contained until appropriate cleanup

methods can be employed. Manufacturer’s recommended methods for

spill cleanup shall be followed, along with proper disposal methods.

The contractor shall follow the recommendations of the appropriate

Hazard Communication Plan of the site construction manager, general

contractor, or site superintendent.

Some spills may need to be reported to the Government immediately.

Specifically, a release of any chemical, oil, petroleum product, sewage,

etc., which may enter waters of the U.S. (which include surface water,

ground water, and dry gullies or storm sewers leading to surface water)

must be reported.

Part I.B.5. Contents and Requirements – Other Controls

Identification of Potential Pollutant Sources

All disturbed and stored soils

Topsoil shall be stockpiled and surrounded by silt fence as shown

on the Grading and Erosion Control Plan in the Appendix of this

report.

Vehicle tracking of sediments

Construction vehicles will be exiting the site from unpaved

surfaces and onto paved surfaces, which presents a significant

possibility for sediment transport.

Management of contaminated soils

There are no known contaminated soils on this site.

Loading and unloading operations

Construction materials loading and unloading activities will exist

on-site. Materials should be neatly placed in appropriate staging

areas. Any materials that are subject to displacement from

blowing wind should be adequately sheltered from the wind.

Outdoor storage activities (building materials, fertilizers, chemicals, etc.)

The quantity of materials stored on the project site shall be limited,

as much as practical, to that quantity required to perform the work

in an orderly sequence. All materials stored on-site shall be stored

in a neat, orderly manner, in their original containers, with original

manufacturer’s labels. Materials shall not be stored in a location

where they may be carried by stormwater runoff into a State Water

at any time.

Vehicle and equipment maintenance and fueling

Vehicle Fueling – there is no known vehicle fueling station to be

installed or used on this site. However, it is anticipated that

construction equipment may be refueled during construction. Spill

prevention and containment measures shall be used at equipment

fueling and servicing areas to prevent the pollution of any state

waters, including wetlands. All spills shall be cleaned up

immediately after discovery, or contained until appropriate cleanup

methods can be employed. Manufacturer’s recommended methods

for spill cleanup shall be followed, along with proper disposal

of 13

methods. The contractor shall follow the recommendations of the

appropriate Hazard Communication Plan of the site construction

manager, general contractor, or site superintendent. Vehicle

refueling should be done in an area surrounded by an earthen berm

to contain any fuel spills. Containment berming should be of

sufficient size to safely contain a spill from the largest tank truck

or other containment device located inside the possible spill area.

In the event of a spill, a method of removal must be provided, such

as application of sorbent materials and the use of a pump or

vacuum truck. Any material removed from the spill site must be

disposed of according to local, state, and federal standards.

Stormwater and snowmelt runoff shall be diverted away from the

containment berming area. Water that collects within the berming

due to rainfall or snowmelt must be treated to meet standards

before release from the spill area.

Vehicle Maintenance – from time to time it may be necessary for

the contractor to perform maintenance on the construction

equipment being used on the site. If possible, major repairs to

construction equipment shall be done off-site. Basic vehicle

maintenance shall be performed in the vehicle fueling area and all

recommendations listed above shall be followed.

Significant dust or particulate generating processes

Should excessive blowing of sediment become apparent, then the

contractor shall water the site for dust control.

Routine maintenance activities involving fertilizers, pesticides, detergents,

fuels, solvents, oils, etc.

The application of fertilizers and pesticides (if used) should be

done using the method and rates recommended by the

manufacturer. These applications shall not cause runoff or

potential damage to receiving bodies of water. Vehicle fuels and

maintenance are described above.

On-site waste management practices (waste piles, liquid wastes,

dumpsters, etc.)

Contractors shall take steps to keep the site reasonably free from

large amounts of construction debris during construction. All

waste materials generated by construction activities shall be

removed from the site. All wastes composed of building materials

must be removed from the construction site for disposal in

accordance with local and state regulatory requirements. No

building material wastes or unused building materials shall be

buried, dumped, or discharged at the site. Any waste materials

stored in dumpsters shall be adequately covered to prevent blowing

debris.

All wastes composed of building materials must be removed from

the construction site for disposal in accordance with local and State

regulatory requirements. No building material wastes or unused

of 13

building materials shall be buried, dumped, or discharged at the

site.

Concrete truck/equipment washing, including the concrete truck chute

and associated fixtures and equipment.

Concrete wash water shall not be discharged to or allowed to

runoff to Waters of U.S., including any surface or subsurface storm

drainage system or facilities. Any concrete wash water shall be

done in a temporary pit on site. The area around this pit shall be

protected with silt fence and the concrete inside the pit shall be

removed when done.

Non-industrial waste sources such as worker trash and portable toilets

Portable toilets located on the site shall be staked in place using t-

posts to prevent them from tipping over during high winds.

Other areas or procedures where potential spills can occur

Spill prevention and containment measures shall be used at

storage, and equipment fueling and servicing areas to prevent the

pollution of any State Waters, including wetlands. All spills shall

be cleaned up immediately after discovery, or contained until

appropriate cleanup methods can be employed. Manufacturer’s

recommended methods for spill cleanup shall be followed, along

with proper disposal methods.

Some spills may need to be reported to the Government

immediately. Specifically, a release of any chemical, oil,

petroleum product, sewage, etc., which may enter waters of the

U.S. (which include surface water, ground water, and dry gullies or

storm sewers leading to surface water) must be reported.

C.5 Final Stabilization and Long-term Stormwater Management

Part I.B.4. Contents and Requirements – Final Stabilization and Long-term

Stormwater Management

Permanent sediment control measures include building construction, paving

of the drive aisles and parking lot, installation of riprap, and the installation of

landscaping and reseeding with a native grass seed mix. The contractor shall consult

the approved Landscape Plan for the proper location, species, and installation

methods for landscaping on the site. If the owner reasonably maintains the

landscaping and reseeding, then it will provide good soil stability and sediment

control. After these permanent measures are installed and final stabilization is

achieved, then temporary measures can be removed. Final stabilization is considered

achieved when all earth disturbing activities at the site have been completed and

uniform vegetative cover has been established with a density of at least 70% of pre-

disturbance levels and such cover is capable of adequately controlling soil erosion.

Soil erosion control measures for all slopes, channels, ditches, or any

disturbed land area shall be completed within twenty-one (21) calendar days after

final grading, or final earth disturbance, has been completed. Disturbed areas and

stockpiles which are not at final grade but will remain dormant for longer than 30

days shall also be mulched within 21 days after interim grading. An area that is going

of 13

to remain in an interim state for more than 60 days shall also be seeded. All

temporary soil erosion control measures and BMP’s shall be maintained until

permanent soil erosion control measures are implemented.

All earth disturbances shall be designed, constructed, and completed in such

a manner so that the exposed area of any disturbed land shall be limited to the shortest

practical period of time.

C.6 Inspection and Maintenance Procedures

Part I.B.6. Contents and Requirements – Inspection and Maintanence

The site construction manager or site inspector responsible for these

measures shall inspect them periodically and after every storm event. This report

recommends that all erosion control measures on the site are inspected a minimum of

once every 7 days OR every 14 days and within 24 hours of a significant rainfall

event except during winter snow pack conditions where no melting is occurring or

when all construction activities are completed.

Based on the results of an inspection, as necessary to properly document

additional or modified BMPs designed to correct problems identified. Revisions to

the SWPPP must be completed within seven (7) calendar days following the

inspection.

Inspection Procedures

The inspection must include observation of the following:

The construction site perimeter and discharge points (including discharges

into a storm sewer system),

All disturbed areas,

Areas used for material storage that are exposed to precipitation,

Other areas determined to have a significant potential for stormwater

pollution, such as demolition areas or concrete washout areas,

Erosion and sediment control measures identified in this SWMP or on the

approved Grading and Erosion Control Plans,

Any other structural BMP’s that may require maintenance, such as

secondary containment around fuel tanks or the condition of spill response

kits.

Qualified Personnel

Inspections must be conducted by qualified personnel (provided by the

operator or cooperatively by multiple operators). “Qualified personnel” means a

person knowledgeable in the principles and practice of erosion and sediment controls

who possesses the skills to assess conditions at the construction site that could impact

stormwater quality and to assess the effectiveness of any sediment and erosion control

measures selected to control the quality of stormwater discharges from the

construction activity.

BMP Maintenance

Any BMP’s found to no longer function as needed and designed or have the

potential to fail without maintenance or modifications must be addressed as soon as

of 13

possible to prevent discharge of pollutants. Inspection should also include

preventative maintenance to proactively ensure continued operation.

BMP Replacement and Additions

See attached Detail sheets for specific maintenance and replacement

requirements for individual BMP’s. Modifications to the erosion control plan and

BMP’s may be necessary from time to time based on site inspections, if site

conditions change, or if site conditions are found to be different than anticipated by

the Grading and Erosion Control Plan. Any additions or deletions of erosion control

measures should be documented on the site copy of the Grading & Erosion Control

Plans.

Record Keeping

A record of all inspections made shall be kept with the SWMP Report for a

minimum of 3 years. A sample BMP Checklist is included in the Appendix of this

report. If the SWMP administrator wishes to use a different Inspection Log format,

then the following information must be included:

1. The inspection date;

2. Names, titles, and qualifications of personnel making the inspection;

3. Weather information for the period since the last inspection (or since

commencement of construction activity if the first inspection) including a

best estimate of the beginning of each storm event, duration of each storm

event, approximate amount of rainfall for each storm event (in inches),

and whether any discharges occurred;

4. Weather information and a description of any discharges occurring at the

time of the inspection;

5. Location(s) of discharges of sediment or other pollutants from the site;

6. Location(s) of BMPs that need to be maintained;

7. Location(s) of BMPs that failed to operate as designed or proved

inadequate for a particular location;

8. Location(s) where additional BMPs are needed that did not exist at the

time of inspection; and

9. Corrective action required including implementation dates.

The inspection report must be signed.

Additionally, records of spills, leaks, or overflows that result in the discharge

of pollutants must be documented and maintained. Information that should be

recorded for all occurrences includes the time and date, weather conditions, reasons

for the spill, etc.

Post-Authorization Records

The following records must be maintained with the SWPPP following authorization

under this permit:

1. Dates when grading activities occur;

of 13

2. Dates when construction activities temporarily or permanently cease on a

portion of the site; and

3. Dates when stabilization measures are initiated.

Employee Training

It is recommended that the contractor/sub-contractor responsible for site

construction be trained and certified as a Colorado Department of Transportation

Erosion Control Supervisor or equivalent.

Persons responsible for ongoing maintenance and inspections of permanent

stormwater quality improvements should be familiar with the Operations &

Maintenance Manual provided.
