Mississippi Stormwater Laws & Regulations

The state operates under the Mississippi Storm Water Program, regulated through the Mississippi NPDES MS4 Permit (Permit No. MSRMS4), and the voluntary state-wide Stormwater Guidance Manuals. Guidance manuals throughout the state were created individually by Phase I MS4s and a group of 19 Phase II municipalities. The state has no numerical standards for post-construction, however the individual MS4s must meet a maintenance and good housekeeping requirement. The general permit and Mississippi Handbook for Construction Sites and Urban Areas are available online.

Frequently Asked Questions

What regulates stormwater discharge at the state level in Mississippi?

The state operates under the Mississippi Storm Water Program, regulated through the statewide NPDES MS4 permit, along with voluntary stormwater guidance manuals developed individually by Phase I MS4s and a group of 19 Phase II municipalities.

Does Mississippi have statewide numeric standards for post-construction stormwater management?

No. The state hasn’t set numerical post-construction standards at the state level. Individual MS4s are instead required to meet a maintenance and good housekeeping requirement, which means specific design and treatment standards vary by which municipality or MS4 a property falls under.

Where can a Mississippi property owner find construction site stormwater requirements?

The Mississippi Handbook for Construction Sites and Urban Areas, along with the general permit, are both published by the state and available for reference. Since the state defers post-construction specifics to local MS4s, the applicable municipal guidance manual for a given property’s jurisdiction is the more direct source for site-specific requirements.
