There are not a lot of changes between the 2008 Multi-Sector General Permit (MSGP) and the proposed 2013 MSGP. The draft 2013 MSGP includes mostly modified requirements from the 2008 MSGP. Following are the most significant changes.
Inspections and Annual Report
Draft 2013 MSGP: No requirement for an annual comprehensive site inspection; Perform quarterly facility inspections and summarize those results in the annual report; Annual report summarizing previous year’s activities – submitted electronically by January 30 of each year
2008 MSGP: Routine Facility inspections must be conducted at least quarterly;
Annual Comprehensive Site Inspection conducted by September 29 each year and submit a report to the EPA annual within 45 days of the inspection
Information about a facility’s Stormwater Pollution Prevention Plan (SWP3) must be available to the public
o A facility can post its SWP3 online and provide a URL when submitting its Notice of Intent
o Or the facility can provide the following on the Notice of Intent (NOI) application:
Description of onsite industrial activities exposed to stormwater and potential spill and leak areas
List of pollutants associated with each industrial activity exposed to stormwater
Description of control measures
Schedule for good housekeeping, maintenance, and required inspections
The draft 2013 MSGP requires that all NOIs, Notices of Termination (NOTs), annual reports, Discharge Monitoring Reports (DMRs), and certain other reporting information be submitted electronically, unless the operator has received a waiver from the EPA Regional office. Waivers are only granted for a one-time use for a single information submittal.
Allowable Non-Stormwater Discharges
Previous permits authorized wash water to be discharged as long as there were no detergents or toxic/hazardous spill material present in the discharge. In addition to detergents, hazardous cleaning products have been specifically prohibited from being discharged under the 2013 MSGP. Washwaters that have come into contact with oil and grease deposits or any other toxic or hazardous materials have been prohibited, unless the deposits have been cleaned up using dry clean-up methods.
Endangered Species Requirements
The procedures operators are required follow to establish their eligibility with regard to protection of threatened and endangered species and critical habitat (Appendix E and Part 188.8.131.52) has been revised to be consistent with the Endangered Species Act.
EPA is now requiring the process be documented by filling out and submitting a worksheet. All operators seeking coverage under the 2013 MSGP must make their eligibility determination in accordance with the requirements in the new permit. Operators cannot check the same criteria they selected in the 2008 MSGP without following the procedures in Appendix E.
Historic Properties Preservation
Appendix F includes a more detailed procedure for determining operator eligibility regarding historic properties in accordance with the National Historic Preservation Act. All operators seeking coverage under the draft 2013 MSGP must make their eligibility determination in accordance with the requirements in the new permit. Operators cannot check the same criteria they selected in the 2008 MSGP without following the procedures in Appendix F.
The draft 2013 MSGP includes additional specificity with regard to what is considered to be an adequate corrective action. Corrective action steps are now required to be taken immediately in order to ensure that pollutant discharges are minimized. Subsequent action must be taken to install a new or modified control and make operational, or complete the repair, before the next storm event if possible, and within 14 calendar days from the discovery of the condition.
Discharges to a Comprehensive Environmental Response Compensation and Liability Act (CERCLA) Site
The draft 2013 MSGP makes facilities discharging to CERCLA sites as defined in Appendix A and listed in Appendix P ineligible for coverage under the permit unless the applicable EPA Regional Office has determined that the facility is eligible for permit coverage. In determining eligibility for coverage, the EPA Regional Office may evaluate whether the facility has included appropriate controls and implementation procedures designed to ensure that the discharge will not lead to recontamination of aquatic media at the CERCLA Site.

Comments must be submitted to the EPA within 60 days.
