<br />Description of the type and locutions of BMP's appropriate for this site and
<br />sufficient to comply with oil applicable requirements of the TMDL implementation
<br />plan and identification of the receiving water and of the areas of project site
<br />discharging to on impoired water that hos on approved TMDL implementation
<br />plan that contains requirements for construction Slormwoter discharges:
<br />Not opp9coble to this project.
<br />Selection of Permanent Stormwater Management System
<br />Will the project create a new cumulative impervious surface greater than or
<br />equal 10 one acre? XX nee — No
<br />1f yes. o water quality volume of )i inch of runoff from this area must be
<br />treated before leoving the site or entering surface waters (1 inch of runoff
<br />from this area if discharging to special waters).
<br />Method(s) to be used to treat runoff from the new impervious surfaces created
<br />by the project:
<br />glir Wet sedinentalion basin dZ lnfilrolion/Filtration basin
<br />Regional ponds — Combination of practices
<br />Description of treatment method(s) to be used, including design information for
<br />each method
<br />THREE wet sedimentation basins will be constructed as shown on the plan. The
<br />basis hove been designed to provide o water quokty volume of 0.5 inch of
<br />runoff from the /NM impervious surfaces that drain to eoch respective basin.
<br />Each basin has also been designed to provide o permanent volume of 1.800
<br />cubic feet of storage below the outlet invert pipe elevation for each acre that
<br />drains to the respective basin. The permanent depth of each basin will be
<br />between 3 and 10 feet. Each basin's outlet is designed to discharge the water
<br />quality volume at no more than 5.66 cubic feet per second per acre of basin
<br />surface area. Access is provided to each basin for future basin maintenance.
<br />The outlet for each basin has been located to minimize the potential for
<br />short- circuiting and includes o floral end section and riprop for energy
<br />dissipation. Each basin has been designed with o stabilized emergency overflow
<br />to accommodate storm events in excess of the basin's hydraulic design.
<br />Description of why it is not feasible to meet the treatment requirement for
<br />water quality volume. This can include proximity to bedrock or rood projects
<br />where the lock of right -of -way precludes the installation of any permanent
<br />stormwater management practices. Description of what other treatment, such
<br />as grossed 'wales, smaller ponds, or grit chambers. will be implemented to
<br />treat runoff prior to discharge to surface waters:
<br />Not Appicable

<br />impervious surfaces will achieve approximately 80R removal of total suspended
<br />solids on on onnuol overage basis:
<br />Not Appkcob7
<br />3. Erosion Prevention Practices
<br />Description of construction phasing, vegetative buffer strips, horizontal slope
<br />grading, and other construction practices to be used to minimize erosion:
<br />Stage the sal disturbing activities to minimize the amount of disturbed soil
<br />prior to stabilization. Disturbed areas will be considered stabilized when covered
<br />MN with materials such as onchored mulch, stoked sod, riprop, wood fiber blanket,
<br />or other materials that prevent erosion from occurring. Grass seeding alone
<br />will not be considered stabilization.
