Stormwater control

Finally, it should be recognized that the approach to stormwater control must be individually designed to suit each particular geographic area. There is no best solution to the problem. 

A determination that stormwater controls are not necessary based on either (A) Total Maximum Daily Load (TMDL) approved or established by ERA that addresses the pollutant(s) of concern for construction activities or (B) For non-impaired waters that do not require TMDLs, an equivalent analysis that determines allocations for small construction sites for the pollutant(s) of concern or that determines that such allocations are not needed to protect water quality based on consideration of existing in-stream concentrations, expected growth in pollutant contributions from all soruces, and a margin of safety. 

Stormwater overflow is chlorinated, and in some plants the influent may be chlorinated for odor 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.

The solution proposed in the paper uses experience of approved rainwater and flood management of developed countries, mainly from stormwater management of SUDS and rest from LID and BMPs, with consideration of Fujian s actual conditions, to design rain adap-tative landscape system for city. Based on linear landscape of retention and drainage which leads water into dotted water landscape of reservoirs, combined permeable paving, it forms primary, intermediate and advanced stormwater reducer made by rain adaptative landscape to perform source, midway and end controls.

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. 

Onshore exploration and production facilities may be subject to several aspects of the CWA national effluent limitation guidelines, stormwater regulations, wetlands regulations, and Spill Prevention Control and Countermeasure (SPCC) requirements.
