Exhibit A
Stormwater BMPs for Construction Staging Area
1) Identify all storm drains, drainage swales and creeks located near the site and make sure all site users are aware of their locations to prevent pollutants from entering them.
2) Install barriers around perimeter of site to prevent runoff from entering and leaving site.
3) Control dust using as little water as possible to prevent runoff.
4) Construct and maintain temporary stabilized construction entrance to minimize tracking of sediment onto public rights-of-way.
5) Immediately remove any sediment spilled, dropped, washed or tracked onto public rights-of-way.
6) Provide protection to nearby storm drain inlets from all sediment and materials from site.
7) Before it rains, sweep and remove materials from surfaces that drain to storm drains, creeks, or channels.
8) Cover exposed piles of soil or construction materials with plastic sheeting or temporary roofs to prevent contact with rainwater.
9) Clean up leaks, drips and other spills immediately so they do not contaminate soil or groundwater or leave residue on paved surfaces.
10) Designate one area of the site, well away from streams or storm drain inlets, for auto parking, refueling, and routine vehicle and equipment maintenance.
11) Maintain all vehicles and heavy equipment. Inspect frequently for leaks.
12) If you must drain and replace motor oil, radiator coolant, or other fluids on-site, use drip pans or drop cloths to catch drips and properly dispose of all spills. Collect all spent fluids, store in separate containers, and recycle whenever possible.
13) Perform major maintenance, repair jobs, and vehicle and equipment washing off-site. If equipment must be washed on-site, do not use solvents, degreasers, or steam cleaning equipment (unless all wash water is collected and disposed up properly off site) and prevent water from entering the storm drain. Direct wash water to a low point where it can evaporate and/or infiltrate.
14) Do not use diesel oil to lubricate equipment or parts.
15) Never hose down “dirty” pavement or impermeable surfaces where fluids have spilled. Use dry cleanup methods (sweeping and use of absorbent materials, cat litter and/or rags) whenever possible, and dispose of used materials properly.
16) Sweep up spilled dry materials immediately. Never attempt to wash them away with water or bury them.
17) Clean up spills on dirt areas by digging up properly and disposing of contaminated soil.
18) Report significant spills to the appropriate spill response agencies immediately.
19) Place trash cans and recycling receptacles around the site to minimize litter.
20) Cover and maintain dumpsters. Check frequently for leaks and use drip pans if necessary. Repair or replace leaking dumpsters as soon as possible. When rain is expected, place dumpsters under roofs or cover with tarps or plastic sheeting secured around the outside of the dumpster.
21) Never clean out a dumpster by hosing it down on the construction site.
22) Make sure portable toilets are in good working order. Check frequently for leaks.
