Stormwater Pollution Prevention Plan (SWPPP)
Water quality standards (WQS) serve to protect the public health or welfare and also enhance the quality of water. WQS are legally defined as “the limits or levels of water quality constitutes or characteristics which are established for the reasonable protection of beneficial uses of water or the prevention of nuisance with a specific area.”
Federal stormwater regulations require industrial facilities included in one of the following categories to acquire an NPDES stormwater permit:
- Mineral, metal, oil, and gas
- Hazardous waste treatment or disposal facilities
- Recycling facilities
- Organization electric plants
- Transportation facilities
- Treatment works
- Construction activities
- Light industrial activity
Level 1 and Level 2 Status – ERA (Exceedance Response Action)
Additional requirements may be assigned to a facility that has been given level 1 status due to an annual NAL exceedance or two exceedances. This includes:
- Facility oversight by a Qualified Industrial Stormwater Practitioner (QISP)
- Implementation of additional BMPs to address pollutants in stormwater runoff
- A Level 1 ERA Report submitted online via the SMARTS database
A facility with level 1 status can quickly be given level 2 status if just one bad sample result is given in the upcoming stormwater year. If a business is given level 2 status, a level 2 action ERA plan needs to be put together by a QISP and submitted to the SMARTS database by January 1st of the stormwater year following the exceedance.
Advanced BMPs will be required and stormwater treatment may be necessary to reduce exceedances below NAL levels. The Level 2 Discharger will also be required to submit a Level 2 Technical report prepared by a QISP, and then also submitted via the SMARTS database.
Facilities must comply with the industrial general permit to avoid lawsuits and penalties.
