Summary

EPA is making the draft MS4 Permit available for public comment.  This action is the result of EPA’s efforts to reissue the MS4 Permit upon its expiration.  The draft permit establishes a “maximum extent practicable” standard for improving water quality with the goal of attaining applicable water quality standards; it also contains specific TMDL-related milestones and wasteload allocations (WLAs) as discharge limits where appropriate.

Additionally, DOEE proposes to provide self-certification under Section 401 of the CWA, for the proposed draft MS4 Permit which currently allows the discharge of stormwater runoff into the waters of the District from its MS4.  In accordance with District of Columbia Law 5-188, certification from DOEE that the proposed draft permit will not violate the District’s Water Quality Standards has been requested and is pending.
