About the Digital Document Library

Welcome to the Minnesota Pollution Control Agency's (MPCA) municipal separate storm sewer system (MS4) Digital Document Library (DDL). The DDL is a space for stormwater program staff to store and circulate example documents that are being used to manage stormwater pollution prevention programs (SWPPPs). In the DDL, you'll find inspection checklists and forms, site plan review checklists, documentation tracking mechanisms, standard operating procedures, photos/graphics, and many more useful materials to help you implement your SWPPP.

Documents in the DDL are available to all site users for download and use. MPCA staff have reviewed all materials to ensure their compliance with the MS4 General Permit prior to posting.

We believe that having example documents will reduce the resources (staff time, financial, etc.) required to implement effective SWPPPs.

IMPORTANT NOTE: Some of the documents in the DDL may not meet the minimum requirements in the new 2020 MS4 General Permit. If you have questions about any of the documents, please contact MPCA MS4 staff.

Photo Library

Finding high quality photographs to use in your outreach materials or other stormwater program activities is difficult. We're compiling pictures into a Photo Library that you can download and use as you see fit. Until we get that up and running, check out the MPCA's Flickr page, or any of the albums below. Images on the Flickr site generally have caption and background information included. We request that you attribute the Minnesota Pollution Control Agency as the source of any image you use.
