Harrison County enforces MS4 stormwater permit requirements. New construction over 1 acre needs stormwater management plans. Gulfport and Biloxi follow Mississippi DEQ NPDES Phase II rules with coastal-specific runoff controls.
Harrison County operates under a Municipal Separate Storm Sewer System (MS4) permit issued by Mississippi Department of Environmental Quality (MDEQ) under EPA NPDES Phase II. Construction sites disturbing 1 acre or more must obtain Construction General Permit coverage and submit a Stormwater Pollution Prevention Plan (SWPPP). Impervious surface limits and on-site detention are common in Gulfport and Biloxi subdivisions. Low-impact development is incentivized near sensitive Gulf Coast watersheds including Back Bay of Biloxi, Biloxi Bay, and Bayou Bernard. Properties draining directly to the Mississippi Sound face stricter water quality limits to protect oyster reefs and coastal fisheries. Post-Katrina rebuilding triggered substantial upgrades to the county's stormwater infrastructure, funded in part by CDBG-DR and FEMA Hazard Mitigation grants.
No SWPPP on 1+ acre site: MDEQ stop-work order + $500-$10,000/day. Illicit discharge to storm drain or Gulf waters: $1,000-$25,000 under MS §49-17. Failure to maintain post-construction BMPs: escalating daily fines.
