The MS4 Phase II General Permit covers the State of Mississippi and authorizes the discharge of storm water runoff into waters of the State from small MS4s, as defined in 40 CFR 122.26(b)(16). The current General Permit expired on February 28, 2021. The reissued general permit will allow the continued discharge of storm water from small MS4s for a five-year period. The staff of the Permit Board has developed the draft general permit and has made a preliminary determination that the MS4 Phase II General Permit meets the requirements of the Federal Clean Water Act and applicable provisions of the Mississippi Air and Water Pollution Control Law. Facilities granted coverage under this permit and adhering to conditions contained therein should operate within State and Federal environmental laws and standards. The staff of the Permit Board is soliciting all relative information pertaining to the proposed general permit, including public comment, to ensure that the final staff recommendation on the draft general permit complies with all State and Federal regulations. Public review and comment on the draft general permit and supporting documentation is an important element in the staff evaluation and resulting recommendation to the Permit Board. The draft permit conditions have been developed to ensure compliance with all State and Federal regulations but are subject to change based on information received as a result of public participation. Persons wishing to comment upon or object to the proposed determinations are invited to submit comments in writing to Mr. Richard Rebich at rrebich@mdeq.ms.gov or to the Permit Board's address shown above, no later than July 10, 2026.

A public hearing will be held if the Permit Board finds a significant degree of public interest in the proposed permit. Persons wishing to request a public hearing may do so by submitting that request in writing to Mr. Richard Rebich at rrebich@mdeq.ms.gov or to the Permit Board's address shown above.
