Can a SWMP be a substitute for a Storm Water Pollution Prevention Plan (SWPPP) as required by the Wisconsin Department of Natural Resources (WDNR) and vice versa?
No, having a SWMP approved by the City Engineer does not relieve the owner of a development or existing industrial facility from submitting a Notice of Intent (NOI) and related SWPPP to the WDNR. Conversely, having a SWPPP approved by the WDNR does not relieve the owner of a development from submitting a SWMP to the City. However, there are normally some common components of a SWMP and a SWPPP that can be used to satisfy both WDNR and City requirements.
