| − | This document provides guidance on how to comply with the site plan review process in the Minnesota Pollution Control Agency’s (MPCA) Authorization to Discharge Stormwater Associated with Small Municipal Separate Storm Sewer Systems (MS4) under the National Pollutant Discharge Elimination System/State Disposal System (NPDES/SDS) Permit Program (MS4 Permit). The MS4 Permit requires you, the permittee, to perform and document site plan reviews for construction projects that disturb one acre or more of land to ensure active and post-construction requirements of your regulatory mechanism (e.g. code, ordinance, law) are met. The MS4 Permit requires your regulatory mechanism to be as stringent as the Authorization to Discharge Stormwater Associated with Construction Activity under the NPDES/SDS Program general permit (MNR100001/Construction Stormwater Permit). | + | This document provides guidance on how to comply with the site plan review process in the Minnesota Pollution Control Agency’s (MPCA) Authorization to Discharge Stormwater Associated with Small Municipal Separate Storm Sewer Systems (MS4) under the National Pollutant Discharge Elimination System/State Disposal System (NPDES/SDS) Permit Program ([https://stormwater.pca.state.mn.us/index.php?title=MS4_General_Permit| MS4 Permit]).

The items identified below are the minimum that must be evaluated during your stormwater site plan review under the MS4 and Construction Stormwater Permits. For each site plan review performed, you must document the project name, location, total acreage to be disturbed, owner and operator of the proposed construction activity, and any stormwater related comments used to approve or deny the project. If you’d like to conduct a more comprehensive review, please see the MPCA’s SWPPP Checklist.
