Have you conducted your Stormwater Annual Site Inspection? Companies with coverage under the National Pollutant Discharge Elimination System (NPDES) Multi-Sector General Permit for stormwater discharges associated with industrial activity must conduct an Annual Comprehensive Site Inspection by September 29, 2012. The period for the inspection is September 29, 2011- September 29, 2012. The annual comprehensive site inspection includes an inspection of the areas where industrial activity may be exposed to stormwater, and a review of corrective actions taken during the reporting period. The Annual Reporting Form (Appendix I of the MSGP) must be mailed to the EPA within 45 days after completion of the inspection.
Companies covered under the 2008 MSGP must continue quarterly visual assessments, routine facility inspections, and required effluent or benchmark monitoring. Results for quarterly benchmark monitoring must be submitted to the EPA within 30 days of receiving the results from the laboratory.
“No Exposure” Certifications obtained under NPDES regulations for stormwater permitting in 2007 are valid for five years and will expire in 2012. Companies should reassess whether the “No Exposure” conditions still apply and renew if applicable. Companies that have never filed a “No Exposure” Certification should consider whether their facility can meet the conditions of the certification, therefore precluding the need for coverage under the MSGP.
