A sediment pond will be installed at the location(s) of the dewatering pump/discharge point.
This pond will be sized to allow for settlement of suspended solids in the dewatering discharge.
' No chemicals or flocculants are expected to be used with the settling pond(s).
Revegetation of disturbed areas remains the most efficient and economical Best Management
' Practice (BMP) for reducing sediment transport from large areas. Roots hold soils in place and
surface growth filters sediment and reduces runoff velocities causing deposition of suspended
' soil particles.
Reclamation and vegetating disturbed areas will be an ongoing process to reduce soil erosion at
the site. Revegetated areas will be mulched following seeding to prevent erosion prior to the
establishment of the plants.
' Mowing will provide the predominant form of weed control and appropriate chemicals will only
be used to control particularly hardy varieties of weeds. Any weed killers used must be
compatible with use near waterways. For example,RoundUp should not be used near running
' water.
4.4 Inspection and Maintenance
Preventative inspections for the vehicles located on site will occur on a daily basis. All vehicles
' will be checked for signs of leaks or other potential problems. Any problems identified will be
corrected immediately. Monthly monitoring inspections of the vehicles will be conducted and
documented on the attached forms. Preventative maintenance for all the equipment will be
conducted on a regular basis and documented on the same forms.
Preventative inspections for the crushing and screening equipment and the asphalt plant will be
' conducted on a monthly basis. Any information regarding maintenance needed or performed
will be noted on the attached forms.
Containment berms surrounding the fuel tanks, the liquiu: at the asphalt plant and the asphalt
plant itself will be inspected monthly. Any problems with the integrity of the berms will be
noted and repaired promptly.
The site will be inspected to insure that all the structural and non-structural BMPs are
' functioning well and any off site discharges have the best water quality attainable from good
management practices. Little discharge, if any, is expected from this site. .
A comprehensive inspection of the site must be conducted no less than twice a year, spring and
fall. A sample inspection form is included which may be modified as necessary. Note any
additional water quality protection procedures implemented, directly on the report or bluelined
drawing for later incorporation to the SWMP. If unforseen erosion occurs, the SWMP should be
revised as necessary to improve discharged stormwater quality.
