DISCUSSION:

The Mississippi Department of Environmental Quality, representing the Governor of the 

State of Mississippi formally requests the portion of DeSoto County, Mississippi that was 

designated as nonattainment for the 2008 National Ambient Air Quality Standard (NAAQS) 

for ozone (O3) be redesignated to attainment pursuant to Section 107(d)(3) of the 1990 

Clean Air Act Amendments (CAA). 

In 2008, the EPA revised the NAAQS for ground-level ozone, setting the standard at 0.075 

parts per million (ppm) averaged over an 8-hour period. Hourly average concentrations are 

recorded in ppm. Running 8-hour averages are computed from the hourly ozone 

concentration data for each hour of the year. The daily maximum 8-hour concentration for a 

given calendar day is the highest of the 24 possible 8-hour average concentrations computed 

for that day. The design value is the statistic to compare the 2008 8-hour ozone NAAQS and 

is a three-year average using the three most recent, consecutive calendar years of monitoring 

data. A violation of the 2008 8-hour ozone NAAQS occurs when the computed design value 

is greater than 0.075 ppm. 

CAA requires the EPA to designate areas as attaining or not attaining that NAAQS. The 

EPA area designations were generally based on air quality monitoring data collected during 

the 2009, 2010, and 2011 ozone seasons. The highest monitor design value in an area was 

used to determine its designation. The CAA then specifies requirements for areas based on 

whether such areas are or are not attaining the NAAQS. 

Because of EPA’s belief that it was contributing to ozone nonattainment for the Memphis 

area, that portion of DeSoto County, Mississippi within the Memphis Urban Area 

Metropolitan Planning Organization (MPO) was designated nonattainment. At that time, the 

monitor in the Crittenden County, Arkansas had a design value above the 2008 8-hour ozone 

NAAQS. However, the monitor located in DeSoto County had a design value of 0.073 ppm, 

which is below the 2008 8-hour ozone NAAQS. The TN-MS-AR Nonattainment Area for 

the 2008 Ozone NAAQS was classified as a Subpart 2 marginal nonattainment area. 

Section 107(d)(3)(E) of the CAA, as amended, states an area can be redesignated to 

attainment if the following conditions are met: 

The EPA has determined that the NAAQS have been attained. For ozone, the areas must 

show that the average of the 4th highest 8-hour ozone values from three (3) complete, 

consecutive calendar years of quality-assured air quality monitoring data must be equal to or 

below 0.075 ppm. 

The applicable implementation plan has been fully approved by the EPA under section 

110(k). 

The EPA has determined that the improvement in air quality is due to permanent and 

enforceable reductions in emissions. To demonstrate this, the State should estimate the

4 

percent reduction (from the year used to determine the design value for designation and 

classification) achieved from federal, state, and local measures. 

The EPA has fully approved a maintenance plan, including a contingency plan, for the areas 

under section 175A. 

The State has met all applicable requirements for the area under section 110 and Part D. 

Appendix V contains the technical data necessary to show that the portion of DeSoto 

County, Mississippi within the Memphis MPO designated as a moderate nonattainment area 

for the 2008 8-hour ozone NAAQS as part of the TN-MS-AR Marginal Nonattainment Area 

has attained and is expected to maintain the 2008 8-hour ozone NAAQS, and has met the 

requirements for redesignation set forth above. 

PURPOSE OF THE REVISION:

The purpose of this SIP Revision is to formally request that the portion of DeSoto County, 

Mississippi that has been designated as nonattainment for the 2008 National Ambient Air

AGENDA

1. Call to Order - Chair 

2. Approval of Minutes of October 22, 2015 Meeting 

3. Commission Approval of Brownfield Obligation Transfer 

On April 26, 2011, the Commission reached a Brownfield Agreement (#5953-11) with the City of 

Picayune and Stockstill Brothers Investment, LLC for the remediation of the former Arizona 

Chemical facility in Picayune, Mississippi. In accordance with Rule 2.1.5.C of Part 3, Chapter 2: 

Final Regulations Governing Brownfield Voluntary Cleanup and Redevelopment in Mississippi, 

the City of Picayune, Stockstill Brothers Investment, LLC and Huey P. Stockstill, LLC jointly have 

provided a petition to the MCEQ that Huey P. Stockstill, LLC has the financial, managerial, and 

technical resources to complete performance of the Brownfield Agreement obligations and agrees 

to complete this performance. The staff of the MDEQ has reviewed the petition, and hereby 

recommends that the Commission issue an order in accordance with the Brownfield Regulations 

approving the transfer of those obligations in Brownfield Agreement #5953-11 from the City of 

Picayune and Stockstill Brothers Investment, LLC to Huey P. Stockstill, LLC. Huey P. Stockstill, 

LLC plans to continue to use the property as an asphalt and concrete facility.

4. Commission Approval of Environmental Covenant 

The staff recommends that the Commission approve the Environmental Covenant between the 

Commission and the Mississippi Department of Transportation regarding the remediation of 

property located adjacent to 5160 Highway 49E in Rising Sun, Mississippi, referred to as the 

“UMOJA Market Site." The UMOJA Market facility was a convenience store that operated 

above-ground fuel tanks. Leaks from above ground storage tanks, fuel dispensers and fuel 

distribution lines have each contributed to petroleum contamination at the site. Therefore, 

remediation of the site is necessary. The portion of the site owned by MDOT serves as a 

right-of-way easement for Highway 49E. The staff of the MCEQ has evaluated the proposed 

Environmental Covenant and believes that, with the conditions and restrictions contained within, 

the site will be in compliance with applicable State and Federal laws and standards and will be 

protective of the public health and the environment.

5. Commission Approval of Environmental Covenant 

The staff recommends that the Commission approve two Environmental Covenants between the 

Commission and Washington County and the Washington County Economic Development 

Authority regarding the remediation of property located in Greenville, Mississippi, referred to as 

the Moore Company facility. The Moore Company facility manufactured automotive parts 

utilizing a stamping operation. Improper handling of chlorinated solvents used as a degreaser in 

their operation contributed to soil and groundwater contamination at the site. Therefore, 

remediation of the site is necessary. The former facility is currently being utilized by a company 

performing a similar operation on the original plant site owned by the Washington County 

Economic Development Authority. The adjacent property owned by Washington County is 

currently leased by a manufacturer of marine components. The staff of the MCEQ has evaluated 

the proposed Environmental Covenant and believes that, with the conditions and restrictions 

contained within, the site will be in compliance with applicable State and Federal laws and 

standards and will be protective of the public health and the environment.

6. Adoption of a Revision to the State Implementation Plan for the Purposes of a Redesignation 

Request and Maintenance Plan for DeSoto County, Mississippi

A public hearing was held on November 5, 2015, concerning a proposed Revision to the State 

Implementation Plan for the Control of Air Pollution (SIP Revision) for the Purposes of a 

Redesignation Request and Maintenance Plan for the portion of DeSoto County, Mississippi that is 
designated as nonattainment for the 2008 National Ambient Air Quality Standard for ground-level 

ozone. The Department plans to request that the U.S. Environmental Protection Agency 

redesignate the aforementioned portion of DeSoto County, Mississippi as attainment for the 2008 

ozone air quality standard pursuant to Section 107(d)(3) of the 1990 Clean Air Act Amendments. 

No comments from the public were received during the 30-day comment period. A transcript of 

the public hearing proceeding has been provided. We are recommending that the Commission 

adopt the SIP Revision.

7. Consideration of the Mississippi State Oil and Gas Board Amended Rule 68 Related to the 

Disposal of Naturally Occurring Radioactive Materials (NORM) Associated with the 

Exploration and Production of Oil and Gas

The Commission is required by statute to approve Mississippi State Oil and Gas Board Rules 

related to disposal of waste products brought to the surface from oil and gas wells. The Oil and 

Gas Board has been directed in a recent Mississippi Supreme Court decision to have the 

Commission approve Oil and Gas Board Rule 68 which is entitled “Disposal of Naturally 

Occurring Radioactive Materials (NORM) Associated with Oil and Gas Exploration and 

Production”. The principal thrust of the Rule is to authorize the surface and subsurface 

landspreading of NORM materials as additional disposal options available to oil and gas operators. 

Natural radioactive elements are present in low concentrations in the earth’s crust and these 

elements are brought to the surface through oil and gas exploration and production activities and 

must be properly disposed of. After the Supreme Court’s decision, MDEQ established a work 

committee to review the Oil and Gas Board Rule 68. The work committee included waste and 

groundwater experts from MDEQ with input from the State Health Department’s Division of 

Radiological Health. The work committee also reviewed other NORM land spreading regulations 

in Texas, New Mexico and Kansas. In addition, the committee met with industry representatives 

and the Oil and Gas Board to understand the provisions of Rule 68 as it was adopted. The 

committee recommended seven (7) changes to strengthen Rule 68, all of which have been adopted 

by the Oil and Gas Board at its meeting on November 18, 2015. The adopted Rule, including the 

changes recommended by MDEQ have been through public comment prior to the adoption by the 

Oil and Gas Board. The recommended changes include the integration of a concentration 

level for Radium 226 or Radium 228 of 5 pCi/g; limitation on the landspreading activity to the 

site of generation; requirement of surface land owner consent for landspreading activities; a 

minimum setback of 300 feet to an inhabited dwelling; clarification that landspreading is limited to 

noncommercial activities; confinement of landspreading activity to NORM-impacted soils and 

NORM-impacted scale; and the defined permit duration or term of up to five (5) years. Copies of 

a comment letter from oil and gas companies; the submittal letter from the Oil and Gas Board; and 

the Findings of Fact, and Conclusion of Law and Order from the Oil and Gas Board which includes 

Amended Oil and Gas Board Rule 68 are being provided to the Commission members for review. 

Staff of MDEQ recommends the Commission approve the Oil and Gas Board Amended Rule 68.
