Description/Abstract: 

When is enough, enough? The Industrial Storm Water General Permit (IGP) is a statewide general National Pollutant Discharge Elimination System (NPDES) permit that regulates storm water discharges from industrial activity. The IGP requires technology-based effluent limitations applicable to industrial activities that are based on best conventional pollutant control technology (BCT) for conventional pollutants, and best available technology economically achievable (BAT) for toxic and non-conventional pollutants. Once a facility has reached Level 2 status, several compliance options are available: implement advanced BMPs; conduct a non-industrial pollutant source demonstration; or conduct a natural background pollutant source demonstration. If the facility decides to implement advanced BMPs, the facility must either implement BMPs to eliminate future Numeric Action Level (NAL) exceedances, or justify what BMPs will be implemented to comply with the Permit even if the BMPs will not eliminate future exceedances of NALs. The IGP has designed standards for all treatment control BMPs. These design standards are generally expected to be consistent with BAT/BCT, to be protective of water quality, and to be effective for most pollutants. But, the best control technology for one industry is not necessarily the best for another. It is possible that Level 2 facilities that implement advanced BMPs may not eliminate future NAL exceedance(s). While an adaptive, management-based process is allowable to iteratively develop and implement BMPs to achieve compliance with the technology-based effluent limitations it is still unclear when a facility can claim it has achieved the BAT/BCT standard. With the iterative process, facilities may eventually eliminate future NAL exceedances or get to BAT/BCT. This presentation will explore a spectrum of facility types, on-site industrial processes, and required specific parameter analysis and pollutant removal. This presentation will also focus on the definition of BAT/BCT for each of these facilities and present a brief comparison of effective BMPs across industry types. Additional considerations presented will include legal implications of Level 2 status and citizen suits in the context of BAT/BCT.
