Brownfields

Agency Mississippi Department of Environmental Quality

The Brownfields page of the Mississippi Department of Environmental Quality (MDEQ), in its Groundwater Assessment and Remediation Division, lists the Brownfield Voluntary Cleanup & Redevelopment Act (§49-35-1 through §49-35-27) and MDEQ's brownfield regulations among its state law. MDEQ's regulations page titles those regulations the Final Regulations Governing Brownfields Voluntary Cleanup and Redevelopment in Mississippi, 11 Miss. Admin. Code Pt. 3, Ch. 2. MDEQ defines a brownfield, under certain legal exclusions and additions, as "real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant."

In a Phase I ESA

ASTM E1527-21 lists state brownfield site records among its standard sources; the general reading of a brownfields listing is on the Brownfields page. This handbook pairs no Mississippi list with that type: MDEQ's Brownfields page links a spreadsheet titled Mississippi's Brownfield Inventory Sites, but the division's main page links the same file address as its CERCLA/UCSS File List, and this handbook did not open it. Five details from MDEQ's definitions and pages shape the search.

The agreement is the record. MDEQ's definitions call a Brownfield Agreement an agreement between the applicant and MCEQ for the remediation of a Brownfield Agreement Site, and a Brownfield Agreement Order an order issued by the Commission which embodies a Brownfield Agreement. Where a property had a Brownfield Agreement, ask for the Brownfield Agreement Order.
The agreement site can reach past the parcel. A Brownfield Agreement Site is the property named in the application plus any other Brownfield Property whose contamination comes from that property, where MCEQ determines that remediation is necessary. Compare the agreement site with the property in front of you.
Some properties fall outside the definition. MDEQ's definition of Brownfield Property leaves out sites proposed for or on the National Priorities List, except those EPA has certified complete or found listing inappropriate; sites under an administrative or judicial order still in effect or an enforcement action commenced under CERCLA or named sections of RCRA; and sites undergoing RCRA corrective action, except those EPA determines have completed it.
Use can be restricted. MDEQ defines an unrestricted site, relevant to a Brownfield Agreement Site, as one whose use is not restricted by an applicable Brownfield Agreement. It defines engineering controls at a Brownfield Agreement Site to include such measures as engineered caps, liner systems, slurry walls, groundwater treatment systems and permanent structures, but not the exclusive use of security fencing. The pages read name no registry of these restrictions or controls, so read the agreement itself.
Proposed agreements have been noticed. When read, the division's public notices page carried one notice of a proposed Brownfield Agreement, with a notice start date of August 28, 2025, and linked a GARD Public Notices Archive, which this handbook did not open.

The Brownfields page also links a Brownfields Liability Protection Application Packet, a list of approved brownfield consulting firms, a Targeted Brownfield Assessment fact sheet and application, a brownfield income tax credit, a Brownfield Annual Report whose file is named for 2021, and a proposed amendment to the brownfield regulations whose file is named for 2023. This handbook did not read those documents. MDEQ says its Brownfield Revolving Loan Fund (BRLF) lets it issue low-interest loans and/or subgrants to eligible applicants for the cleanup of brownfield sites.

Where to look a site up

MDEQ's Brownfields page links a spreadsheet titled Mississippi's Brownfield Inventory Sites. The division's main page links the same file address as its CERCLA/UCSS File List. This handbook did not open the file and does not say what it holds.
The same page links a 2002 City of Jackson Brownfield Inventory.
The division's notices are on the Groundwater Assessment and Remediation Division Public Notices page, which links a GARD Public Notices Archive.

Getting the file

MDEQ's route is a written public records request that names the facility, the city and county where it is located, and the type of information wanted; see Public records requests.
