As my colleague Missy Foster recently reported, the deadline for compliance with California’s new Industrial Storm Water permit (2014 Permit) is fast approaching. There is a lot to learn about the 2014 Permit before it takes effect on July 1, 2015.
The 2014 Permit contains numerous new acronyms. Below is the quick A to Z of the 2014 Permit’s new and most important acronyms.
- BMPs – Minimum Best Management Practices
- Dischargers will now be required to implement minimum BMPs, or explain why they do not apply. In contrast, the 1997 Permit allowed Dischargers to consider which non-structural BMPs should be implemented and which structural BMPs should be considered for implementation when non-structural BMPs are ineffective.
- Dischargers will also be required to implement advanced BMPs (mostly structural BMPs) when implementation of minimum BMPs are insufficient, subject to the limits of the Clean Water Act.
- ERA – Exceedance Response Actions
- All Dischargers, regardless of historical discharge, start at baseline status. Exceedance of a NAL will cause a Discharger to move from baseline to Level 1. Exceedance of a NAL while at Level 1 will cause a Discharger to move from Level 1 to Level 2.
- Dischargers at Level 1 or Level 2 status must perform Exceedance Response Actions (ERAs), including report preparation and possible additional BMP implementation.
- NALS – Numeric Action Levels (NALs) and NAL Exceedances
- Dischargers must analyze pH, total suspended solids (TSS) and oil & grease (O&G) against new “numeric action levels” (NALs). Specific industries may have NALs for other pollutants.
- A Discharger can exceed a NAL by exceeding “instantaneous” maximum limits in two samples in one year, or by exceeding “annual” limits based on the average pollutant concentration in all samples in one year.
- NEC – No Exposure Certification
- The 2014 Permit eliminates the 1997 Permit’s conditional exclusion for light industries that do not expose activities to storm water.
- Instead, Dischargers that do not expose activities to storm water can file a “no exposure certification” (NEC) and site map by October 1, 2015, and pay a fee to the State Board.
- QSE – Qualifying Storm Event
- A “qualifying storm event” (QSE) is defined as a precipitation event that: (1) produces a discharge for at least one drainage area; and, (2) is preceded by 48 hours with no discharge from any drainage area.
- SMARTS – Storm Water Multiple Application and Report Tracking System
- Dischargers must submit and certify all reports electronically via the State Board’s website database, called the Storm Water Multiple Application and Report Tracking System (SMARTS).
- SMARTS can be found here, although the website is not yet ready to accept filings for the 2014 Permit.
