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. 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.
This is the second publication of the draft permit for public notice and comment. The permit was previously published in November 2016. Comments were received through January 17, 2017. As a result of the comments received, and additional information received, EPA has made changes to the draft permit which require additional public review prior to the reissuance of the final permit.
