The SWMP Administrator becomes the contact for all SWMP-related issues and is the person responsible for its accuracy, <br />completeness, and implementation. Therefore, the SWMP Administrator should be a person in an authoritative position. <br />Larger facilities may want to develop a "SWMP team" in order to share the responsibilities and generate greater awareness <br />and participation. <br />b) Materials Handling and Spill Prevention - Where materials can impact stormwater runoff, BMPs that reduce <br />the potential for contamination shall be described. For example, materials should be stored and handled in <br />covered areas whenever possible to prevent contact with stormwater; fuels and other chemicals should be <br />stored within berms or secondary containment devices to prevent leaks and spills from entering stormwater <br />runoff. <br />When selecting BMPs, the most important ones to evaluate first are those which limit the source of the pollutant. It is much <br />more efficient, from both a cost and environmental standpoint, to prevent the pollution in the first place than to clean up <br />contaminated stormwater. For example, a BMP requiring that any vehicle maintenance that involves fluid exchange must <br />take place indoors, results in the removal of a pollutant source (i.e., oil/hydraulic fluids) from possible contact with <br />stormwater. <br />Good housekeeping measures, such as cleaning and maintenance schedules, trash disposal and collection practices, <br />grounds maintenance, etc., can be included here. <br />c) Erosion and Sediment Controls - Describe BMPs that will be used to reduce erosion and prevent sediment <br />delivery to State waters. These should include structural (such as silt fences, sediment ponds, drop <br />structures, check dams) and non-structural (such as mulching and revegetation) methods. <br />BMPs can describe a wide range of management procedures, schedules of activities, prohibitions or practices and other <br />management practices. BMPs can include operating procedures, treatment requirements and practices to control plant site <br />runoff, drainage from raw materials storage, spills or leaks. Nonstructural BMPs are mainly definitions of operational or <br />managerial techniques. Structural BMPs include physical processes ranging from diversion structures to oil/water separators <br />to retention ponds. <br />The BMPs selected are up to the judgment of the individual permittee. However, it is important to note that a fully <br />implemented SWMP will constitute compliance with Best Available Technology (BAT) and Best Conventional Technology <br />(BCT), as mandated under the Federal Clean Water Act. This means that, in order to comply with your permit, the <br />appropriate measures must be taken in keeping with the pollutant(s) involved and the risk potential at the facility. <br />d) Identification of Discharges other than Stormwater - The stormwater conveyance system on the site shall be <br />evaluated for the presence of discharges other than stormwater, such as mine drainage, spoil springs, <br />sanitary waste, or process water of any kind. The SWMP shall include a description of the results of any <br />evaluation for the presence of discharges other than stormwater, the method used, the date of the <br />evaluation, and the on-site drainage points that were directly observed during the evaluation. <br />A number of discharges other than stormwater may not require a CDPS Industrial Wastewater Discharge <br />permit and are considered Allowable Non-Stormwater Discharges. Flows from fire righting activities, <br />landscaping irrigation return flow or springs (except spoil springs) that are combined with stormwater <br />discharges associated with industrial activity must be identified in the SWMP. <br />In other words, only stormwater can be conveyed by the stormwater drainage system. Examples of potential illicit <br />connections include floor drains and toilets in maintenance buildings, chemical storage buildings, etc. There are several <br />methods of determining whether or not illicit connections exist. Acceptable procedures include dry weather observations of <br />outfalls or other appropriate locations, analysis and validation of accurate piping schematics, dye tests, etc. <br />Note - if illicit connections are discovered, corrective measures must be taken. <br />B3
