The Municipal Separate Storm Sewer Systems (MS4) Permit Total Maximum Daily Load (TMDL) Waste Load Allocations (WLAs) List includes U.S. Environmental Protection Agency (EPA) approved TMDL WLAs for permitted MS4s. If you are assigned a WLA in a TMDL that was approved by EPA prior to the effective date of the new MS4 permit you are required to meet MS4 permit requirements related to TMDL WLAs. Note: this list is subject to change if additional WLAs are approved by EPA prior to the effective date of the new MS4 permit.
