BALTIMORE CITY MS4 RESTORATION AND TMDL WIP

ms4_photo_story

The Baltimore City Municipal Separate Storm Sewer System (MS4) and Total Maximum Daily Load (TMDL) Watershed Implementation Plan (WIP) is a requirement of the City’s MS4 Permit, which was issued on December 27, 2013. The WIP is a plan for achieving the 20% restoration requirement set out in the permit, in addition to attaining applicable waste load allocations (WLAs) for each established or approved Total Maximum Daily Load (TMDL) for each receiving water body.

The WIP presents the strategies to meet the restoration and TMDL goals as specified in the current MS4 permit. Specifically, the WIP will provide the basis for the City to:

  1. Provide Best Management Practices (BMPs) to restore an equivalent of 20% of the existing impervious
    area which stormwater runoff is not currently managed to the maximum extent practicable (MEP).
  2. Meet TMDL Waste load Allocations (WLAs) approved by the Environmental Protection Agency (EPA).
  3. Educate and involve residents, businesses, and stakeholder groups in achieving measurable water quality improvements.
  4. Establish a reporting framework that will be used for annual reporting as required in the City’s National Pollutant Discharge Elimination System (NPDES) MS4 Permit.
  5. Identify necessary maintenance, adaptive management, staffing, and financial strategies to implement the WIP.
