Industrial stormwater, with great stormwater control measures, at a manufacturing facility

About the Digital Document Library

Welcome to the Minnesota Pollution Control Agency's industrial stormwater Digital Document Library! The ISW DDL is a space for staff of industrial facilities and other state's stormwater programs to share example documents that are being used to implement best management practices (BMPs) or protect stormwater from pollutants. All documents in the ISW are free for anyone to use. Just download a document you're interested in, tailor it to your facility, and begin improving water quality at your facility. In the ISW DDL, you'll find inspection and checklists and forms, site plan review checklists, documentation tracking mechanisms, standard operating procedures, and many more useful materials to help you implement your stormwater management program.

We believe that having multiple guidance documents and example documents will reduce the resources (staff time, financial, etc.) required to implement effective stormwater management.

To find what you're looking for, go to the appropriate topic area below.

  • Applicability Industrial facilities need to determine if they need industrial stormwater permit coverage. Any facility that is engaged in regulated narrative activity or a regulated primary SIC code needs to apply for permit coverage or certify for No Exposure.
  • No Exposure Consider keeping all materials and activities indoors and save time, money, and resources!
  • Stormwater control measures Identify stormwater management practices (also known as Best Management Practices or BMPs) that you will install at your facility is a SWPPP requirement.
  • Stormwater pollution prevention plan (SWPPP) - The SWPPP is your plan and guide to understanding and managing stormwater runoff.
  • Training Employee training should be a major component of any SWPPP. Employee training is also an integral part of other control measures and may be done in conjunction with other training programs.
  • Sampling requirements Permittees are required to sample quarterly until results from four separate quarters average below the permit benchmark value(s).
  • Miscellaneous -This section will provide tips and suggestions to common problems, violations and facility-specific challenges.
