Industrial Stormwater Guidance
- Updated Industrial SWPPP Guidance - Provides guidance on developing a SWPPP that meets MSGP requirements.
-
Updated EPA Industrial SWPPP Template (docx)
- Provides a template that industrial facilities can use to create their SWPPPs.
Note: All facilities must have a SWPPP completed before submitting their NOI for coverage under the 2021 MSGP. - Updated Additional MSGP Documentation Template (docx) - Provides a form for keeping records on monitoring, inspection, maintenance, visual evaluation and corrective action activities.
- Updated Industrial Stormwater Monitoring and Sampling Guide - Explains how to conduct visual and analytical monitoring of stormwater discharges. Can be used by facilities required to comply with MSGP’s monitoring requirements as well as facilities subject to state-issued industrial stormwater permits.
- AIM Calculator (xlsx) - Helps operators determine their additional implementation measure (AIM) level status in accordance with Part 5.2 of EPA's Multi-Sector General Permit (MSGP).
- EPA Region 10 Questions and Answers Regarding the MSGP - Provides answers to commonly asked questions in EPA Region 10 (Alaska, Idaho, Oregon, and Washington).
- Approved or Established TMDLs - Provides links to sources and program contacts related to approved or established TMDLs for waterbodies located in jurisdictions covered under the Multi-Sector General Permit (MSGP).
- NPDES Compliance Monitoring Strategy - Outlines inspection and compliance goals for the entire NPDES program, including stormwater. This new strategy, which takes effect in 2009, places increased emphasis on wet weather issues, particularly stormwater sources, and sets ambitious targets for audits and inspections of Phase I and II MS4s, construction sites, and industrial facilities.
