Some non-stormwater discharges do not <br />Nutrients ✓ <br />include pollutants and may be discharged to the storm drain. <br />Trash <br />These include uncontaminated groundwater and natural springs. <br />Metals ✓ <br />There are also some non-stormwater discharges that typically do <br />Bacteria ✓ <br />not contain pollutants and may be discharged to the storm drain <br />✓ <br />with conditions. These include car washing, air conditioner <br />Oil and Grease <br />condensate, etc. However there are certain non-stormwater <br />Organics ✓ <br />discharges that pose environmental concern. These discharges <br />may originate from illegal dumping or from internal floor drains, <br />appliances, industrial processes, sinks, and toilets that are <br />connected to the nearby storm drainage system. These <br />discharges (whichmay include: process wastewaters, cooling <br />waters, wash waters, and sanitary wastewater) can carry <br />substances such as paint, oil, fuel and other automotive fluids, <br />chemicals and other pollutants into storm drains. They can <br />generally be detected through a combination of detection and <br />elimination. The ultimate goal is to effectively eliminate non- <br />stormwater discharges to the stormwater drainage system <br />through implementation of measures to detect, correct, and <br />enforce against illicit connections and illegal discharges of <br />pollutants on streets and into the storm drain system and creeks. <br />Approach <br />Initially the industry must make an assessment of non- <br />stormwater discharges to determine which types most be <br />eliminated or addressed through BMPs. The focus of the <br />following approach is in the elimination of non-stormwater <br />discharges. <br />CASQA <br />rallf•rM• <br />S[orm•r•br <br />o•all <br />Mroclatl•n <br />January 2003 California Stormwater BMP Handbook 1 of 6 <br />Industrial and Commercial <br />wwwcabmphandbooks com <br />
