Stormwater, runoff control

Identification of sewers, discharge locations and inputs to the final effluent or ETP (if one exists). The main streams and inputs to the ETP (if present) should be identified, along with sub-component streams (information should already be available as part of a Toxicity Prevention/Response Plan described in Section 5.1). Inputs should include process, site-runoff, stormwater runoff and groundwater sources. A description of the process and operation at each location should also be provided (including operation frequency). Locations with existing monitoring equipment and flow control devices should also be identified.

Sewage treatment plants are very efficient at removing lead and other heavy metals from raw sewage. They thus act as effective controls on lead discharges not only within domestic sewage but also from industrial sources and urban stormwater runoff, both of which are frequently directed to sewage treatment plants.
