Industrial Stormwater

Announcement – Public Notice

The Permit Board on Environmental Quality is proposing to reissue the statewide Industrial Stormwater General Permit for Industrial Activities (MSR10) (Previously Baseline Storm Water General Permit for Industrial Activities). This permit covers the State of Mississippi and authorizes the discharge of storm water runoff into waters of the State from regulated industrial activities. If reissued, this general permit would be active for a five year period. This general permit will replace the previous general permit that expired October 31, 2020. The general permit draft  can be found HERE, the draft Fact Sheet can be found HERE, and the Public Notice can be found HERE. The thirty (30) day public notice starts October 30, 2020. Written comments should be submitted to the following address no later than the end of the thirty (30) day public notice:

Chief, Environmental Permits Division
Mississippi Department of Environmental Quality
Office of Pollution Control
P.O. Box 2261
Jackson, Mississippi 39225

A Re-Coverage Form and Letter of Instruction will be mailed to everyone that holds an active coverage. Existing coverage holders may request re-coverage under the reissued general permit by completing and submitting the Re-Coverage Form within 90 days of the date of the Letter of Instruction. Both the form and letter will be available for access below upon general permit reissuance.


The Baseline General Permit was reissued on November 17, 2015 and expires October 31, 2020.  MDEQ will administratively continue the permit issued on November 17, 2015.  This permit will remain in full force and effect until a replacement permit has been issued.  Coverage holder should comply with the requirements in the existing permit during this period.  When a replacement permit has been issued, coverage holders will receive a letter containing instructions for reapplying for coverage.

Due to the circumstances surrounding the state’s response to the COVID-19 situation and for your convenience and safety, EPD is temporarily accepting electronic applications. You can submit electronic applications for general permit coverages here.
