Industrial Stormwater Treatment Solutions: How Effective Are They?
In line with the conference theme, “Source to Resource,” California’s new Industrial Storm Water General Permit (IGP) has been implemented to improve storm water quality throughout the state. The IGP incorporates an Exceedance Response Action (ERA) process to facilitate Best Management Practice (BMP) improvements and as a result many industrial facilities are being driven towards implementing storm water treatment solutions. Thus far, common treatment alternatives involve either active tank-based modular systems or passive flow-through systems. While both system types have shown positive results, both can be costly and troublesome to maintain. This presentation will summarize treatment system effectiveness from dozens of industrial facilities throughout California, providing insight into common issues, considerations, and challenges dischargers are facing. With more stringent Total Maximum Daily Load (TMDL) Action Levels (TALs) being incorporated into the IGP, the technological considerations and ability to meet action levels are becoming more demanding and it is important for both industrial dischargers and practitioners to understand the end goal these treatment systems.
