As many of you have heard, after years of deliberation the California State Water Resources Control Board adopted a new stormwater “Industrial General Permit (IGP) on April 1, 2014. This new general permit will replace the current IGP effective July 1, 2015. Even though the effective date is almost a year away, the new IGP significantly expands the scope of the current IGP and also establishes a variety of new requirements and it’s not too soon to start preparing! Significant changes include:
- Regulation of more industries
- Minimum BMPs (as opposed to “suggested”)
- Specific Monitoring and Sampling Requirements and Associated “Numeric Action Levels” (NALs)
- Requirements for “Qualified Industrial Stormwater Practitioners” (QISP)
- Compliance Groups (as opposed to Group Monitoring)
- Fire-hydrant or response system flushing;
- Water related to the operation, maintenance, or testing of potable water systems;
- Drinking fountain water and atmospheric condensate (refrigeration, A/C, compressors)
- Irrigation drainage and landscape water;
- Uncontaminated groundwater, drainage, footing drainage;
- Seawater infiltration,
- Cooling towers mist (not blowdown or intentional discharges).
- “Pollution Prevention Team” an contact information
- Site Map,
- Description and assessment of Potential Pollution Sources
- Advanced BMPs, if applicable
- Observation and Monitoring Plan
- Annual Comprehensive Facility Compliance Evaluation (Annual Evaluation);
