The SWMP document is intended to identify and describe the best management practices (BMPs) selected by the (City) to meet the requirements of the six minimum control measures (MCMs) described in the permit, why those BMPs were selected in light of local water quality issues, and performance standards for BMP implementation. The six MCMs are: 1. Public Education and Outreach on Storm Water Impacts 2. Public Participation / Involvement 3. Illicit Discharge Detection and Elimination 4. Construction Site Storm Water Runoff Control 5. Post-Construction Storm Water Management in New Development and Redevelopment 6. Pollution Prevention / Good Housekeeping for Municipal Operations The NPDES small MS4 permit was reissued on September 11, 2014 (NPDES Permit No. OHQ000003) and requires MS4 communities which are renewing coverage under this permit to update their SWMP to be consistent with the permit and submit the updated SWMP to Ohio EPA for review. Permit No. OHQ requires that where applicable, BMPs shall be selected to address U.S. EPA approved Total Maximum Daily Load (TMDL) recommendations for identified water quality problems associated with MS4 discharges within the s watershed(s) Total Maximum Daily Load (TMDL) Overview The MS4 Permit requires that where applicable, BMPs shall be selected to address U.S. EPA approved TMDL recommendations. The is situated at the intersection of four HUC- 8 watersheds: Auglaize River, Upper Maumee River, Lower Maumee River, and Tiffin River. Information on each watershed and respective current TMDL status is described in the table below. For those watersheds without a TMDL, the latest findings from water quality studies are reported.
