contractor with erosion prevention information and Best Management Practices (BMP's) to be

used during project construction to prevent the generation of erosion products and their

transport to environmentally sensitive areas. Environmentally sensitive areas include all

designated resource areas downstream of the Site, and those areas of the Site that do no need

to be altered for development purposes.

The most important BMP is maintaining a rapid construction process, resulting in prompt

stabilization of surfaces, thereby reducing erosion potential. Given the primacy of rapid

construction, the ESCP has been designed to allow construction progress with essentially no

hindrance by the erosion control methods prescribed. THE ESCP has also been designed with

sufficient flexibility to allow the contractor to modify the suggested methods as required to suit

seasonal, atmospheric, and site specific physical constraints. Another important BMP is the

prevention of concentrated water flow. Sheet flow does not have the erosive potential of a

concentrated rivulet. The ESCP recommends construction methods that allow localized erosion

control and a system of construction which inhibits the development of shallow concentrated

flow. These BMP's should be maintained through the construction process.

RESPONSIBILITY OF THE CONTRACTOR

The contractor shall be solely responsible for erosion and sedimentation control at the Site.

The contractor shall utilize a system of operations and all necessary erosion and sedimentation

control measures, even if not specified herein or elsewhere, to minimize erosion damage at the

Site. The BMP's presented in the ESCP should be used as a guide for erosion and

sedimentation control and are not intended to be considered specifications for construction.

BMP's FOR CONSTRUCTION

Clearing:

- Vehicles used the wood clearing process shall remain within the approved limits of work.

- Wheel ruts shall be filled in and graded to prevent concentration of storm water runoff.

- Vehicle tracks leading downhill shall be blocked during periods of intense precipitation

by hay bales, dikes, or silt fences which shall be installed to entrap the sediment.

- Consideration shall be given to chipping of brush and branches that generate wood chip

mulch for the use in stabilization of disturbed surfaces.

- No spoil (e.g., tree stumps) shall be disposed of by burying.

Grubbing, Stripping and Grading:

- Erosion Controls devised shall be in place as shown on the design plans before grading

commences.

- A Crushed Stone Construction Entrance shall be installed as soon as the start of

construction. The stabilized construction entrance will be inspected daily for sediment

tracked on the road, for clean gravel, and to make sure that the all traffic uses the

stabilized entrance when leaving the site.

- As much topsoil as possible shall be stockpiled for on-site use.

- Stripping shall be done in a manner which will not concentrate runoff. If precipitation is

expected, earthen berms shall be constructed around the area being stripped, with a silt

fence or hay bale dikes located in an arc at the low point of the berm.

- If intense precipitation is anticipated, hay bales, dikes and/or silt fences shall be used as

required to prevent erosion and sediment transport. The materials required shall be

stored on site al all times.

- If water is required for soil compaction, it shall be added in a uniform manner that does

not allow excess water to flow off the area being compacted.

- Dust should be held at a minimum by sprinkling exposed soil with at appropriate amount

of water.

Maintenance of Disturbed Surfaces

- Runoff shall be diverted from disturbed side slopes in both cut and fill.

- Mulching may be used for temporary stabilization.

- Hay bale dikes or silt fences shall be set where required to trap sediment and shall be

maintained on a continual basis throughout the construction process.

Loaming and Seeding

- Loaming and seeding of slopes shall be an ongoing construction process and is not

limited to any one phase of construction.

- Loam shall not be placed unless it is to be seeded directly thereafter.

- All disturbed areas shall have a minimum of 4" of loam placed before being seeded and

mulched.

- Consideration should be given to hay-mulching, especially on slopes in excess of 3 to 1.

- Loamed and seeded slopes shall be protected from washout by mulching or other

acceptable slope protection until vegetation begins to grow.

- All exposed areas shall be stabilized within 30 days of being excavated even if further

work is anticipated for that particular area.

Storm Water Collection System Installation

- Staked hay bales shall be installed around each catch basin upon installation and shall

remain in place until the binder pavement is installed. After binder pavement, Siltsacks

shall be installed in each catch basin and shall be maintained until all upgradient

contributing areas are stabilized.

- Check dams (crushed stone, staked hay bales, or staked silt socks) shall be installed

along the roadway gutter. The check dams shall be maintained until upgradient

contributing areas are stabilized.

Stabilization of Surfaces

- Stabilization of surfaces shall be an ongoing process.

- Stabilization of surfaces included the placement of pavement, rip rap, bark mulch and

the establishment of vegetated surfaces.

- Upon the completion of construction, all surfaces shall be stabilized even though it is

apparent that the future construction efforts will cause their disturbance. In no case left

open greater than 30 days.

- Vegetated cover shall be established during the proper growing season and should be

enhanced by soil adjustment for proper pH, nutrients and moisture content.

- Surfaces that are disturbed by erosion processes, vandalism or by construction shall be

stabilized as soon as possible, in no case greater than 30 days.

- Hay-mulching of grass surfaces is recommended, especially if seeding of the surfaces

is required outside the normal growing season.

- Erosion control blankets are recommended for steep slopes (greater than 3:1).

NOTES:

1. THE TEMPORARY EARTH STOCKPILE LOCATIONS SHOWN ARE INTENDED TO BE

REPRESENTATIVE OF AVAILABLE AREAS WHERE STOCKPILES MAY BE LOCATED.

STOCKPILES ARE TO BE LOCATED IN AREAS OF RELATIVELY FLAT SLOPES OUTSIDE OF

IMMEDIATE WORK AREAS AND AT A MINIMUM OF 100' FROM ALL JURISDICTIONAL WETLAND

RESOURCE AREAS.

2. DEWATERING AREAS, IF REQUIRED, ARE TO BE LOCATED IN AREAS OF RELATIVELY FLAT

SLOPES OUTSIDE OF IMMEDIATE WORK AREAS AND AT A MINIMUM OF 100' FROM ALL

JURISDICTIONAL WETLAND RESOURCE AREAS.

3. NO MACHINERY WILL BE STORED WITHIN 100' OF ANY RESOURCE AREA, AND ALL MACHINERY

WILL BE INSPECTED DAILY FOR LEAKING FLUIDS. CHEMICALS, FERTILIZERS, PESTICIDES,

HERBICIDES, ETC. SHALL NOT BE USED OR STORED WITHIN 100' OF A JURISDICTIONAL

RESOURCE AREA.

4. THE CHECK DAMS IN THE UPGRADIENT SWALES SHALL BE THE PRIMARY SEDIMENT TRAPS

DURING CONSTRUCTION.

5. THIS PROJECT IS SUBJECT TO THE REQUIREMENTS OF THE CONSTRUCTION GENERAL

PERMIT UNDER THE EPA'S N.P.D.E.S. PROGRAM AND MUST BE IMPLEMENTED IN

ACCORDANCE WITH THE S.W.P.P.P. PREPARED FOR THE PROJECT.
