C~ APPENDIX A -SWMP (cont.) Page B-3 The SWMP Administrator becomes the contact for all SWMP-related issues and is the person responsible for its accuracy, completeness, and implementation. Therefore, the SWMP Administrator should be a petson N an authoritative position. Larger facilities may want to develop a "SWMP team' m order to share the responsibilities and generate greater awareness and participation. b) Materials Handling and Spill Prevention- FYhere materials can impact stormwater runoff, BMPs that reduce the potential for contamination shall be described. For example, materials should be stored and handled in covered areas whenever possible to prevent contact with stormwater; fuels and other chemicals should be stored wit/tin berms or secondary containment devices to prevent leaks and spills front entering stormwater runoff: Whrn selecting BMPs, the most vnportant ones to evaluate first are those which Ivnit the source of the pollutant It is much more elTicien[, from both a cost and environmental standpoint, to prevent the pollution in the first place than to clean up contaminated stormwater. For example, a BMP requiring that any vehicle maintenance that involves fluid exchange must take place indoors, results in the removal of a pollutant source (i.e., oil/hydraulic fluids) from possible contact with stormwater. Good housekeeping measures, such as cleaning and maintenance schedules, trash disposal and collecdon practices, grounds maintenance, etc, can be included here. c) Erosion and Sediment Controls - Describe BMPs that will be used to reduce erosion and prevent sediment delivery to Stale waters. These should include structural (such as silt fences, sedimentponds, drop strunures, check dams) and non- atructural (such as mulching and revegetatian) methods. BMPs can describe a wide range of management procedures, schedules of activities, prohibitions or practices and other rnartagernent practices. BMPs can include operating procedures, treatment requirements and practices to control plant site runoff, drainage from raw mazerials storage, spills or leaks. Nonsmicmal BAs are ma'udy definitions of operational or triartagerial techniques. Structural BMPs include physical processes ranging ;iom diversion structures w oiUwater separators [o retention ponds. The BMPs selected are up to the judgment of the individual pemutree. However, it is important to note that a firl ly vnplemented SWMP will constitute compliance wtth Best Available Technology (BAT) and Best Conventional Technology (BCT'), as mandated under the Federal Clean Water Act. Tlus means that, in order to comply with your pemrit, the appropriate measures must be taken in keeping with the pollutant(s) involved and the risk potential a[ the facility. d) Jdentification o(Discharees other than Storm water -The stormwater conveyance system on the site shall be evaluated jar the presence ojdischarges other than stormwater, such as mine drainage, spoil springs, sanitary waste, or process »~ater of any kind. The SWMP steal! include a description ojthe results ajany evaluation jar the presence ojdischarges other than stormwater, [he method used, the date ojthe evaluation, and the on-site drainage points that were directly observed during the evaluation. A number ojdisclmrges other tlmn storm»~aler map not require a CDPS lndustria! Wastewater Disthargepcrrnil and are considered Allowable A'on-Storm water Discharges. F/owsjrom firefighting activities, landscaping irrigation return j/o»~ or springs (except spoil springs) that are combined with stormwater discharges associated with industrial activity must be identified in (he SWMP. In other words, only stormwater can be conveyed by the stomrwater drainage system. Examples of potential illicit cornecdons include floor drains and toilets in mantenance buildings, chemical storage buildings, etc. There are sevtaal methods of detemtining whedter or not illicit connections exist. Acceptable procedures include dry weather observations of outfalls or other appmpriate locations, analysis and va4idation of actuate piping schematics, dye tests, etc. Note - it i1Gci[ connections are discovered, corrective measures must betaken.
