DISCUSSION:

The purpose of this State Implementation Plan (SIP) Revision is to implement Sections 

182(a)(1) and 182(a)(3) of the Clean Air Act (CAA), as amended (42 United States Code 

(U.S.C.) 7401 et seq.), with respect to the requirements for an Emissions Statement and an 

Emissions Inventory for the Ozone Nonattainment Area of DeSoto County, Mississippi. 

PURPOSE OF THE REVISION:

The purpose of this State Implementation Plan (SIP) Revision is to implement Sections 

182(a)(1) and 182(a)(3) of the Clean Air Act (CAA), as amended (42 United States Code 

(U.S.C.) 7401 et seq.), with respect to the requirements for an Emissions Statement and an 

Emissions Inventory for the Ozone Nonattainment Area of DeSoto County, Mississippi. 

Section 182(a)(3)(B) of the CAA requires Marginal and above areas to submit an emissions 

statement within 2 years of designation as nonattainment. Specifically it provides that the 

emissions statement must: “...require that the owner or operator of each stationary source of 

oxides of nitrogen or volatile organic compounds provide the state with a statement, in such 

form as the Administrator may prescribe (or an equivalent alternative developed by the 

state), for classes or categories of sources, showing the actual emissions of oxides of 

nitrogen and volatile organic compounds from that source. The first such statement shall be 

submitted within 3 years after the date of the enactment of the CAA Amendments of 1990. 

Subsequent statements shall be submitted at least every year thereafter.” Appendix U 

contains new state regulations which will implement the Emissions Statement requirement 

for any areas designated as nonattainment for the National Air Quality Standard for groundlevel ozone. The new regulations are 11 Mississippi Administrative Code, Part 2, Chapter 

11, Regulations for Ambient Air Quality Nonattainment Areas. The regulations are 

applicable to sources in DeSoto County, Mississippi as well as any other areas that might be 

designated nonattainment in the future. 

CAA section 182(a)(1) requires that Marginal and above ozone nonattainment areas submit a 

base year emissions inventory for the nonattainment area 2 years after designation as 

nonattainment. The emissions are reported as tons/average summer day of pollutant. In 

accordance with the requirements of EPA’s Emissions Inventory Guidance for 

Implementation of Ozone and Particulate Matter National Ambient Air Quality Standards 

(NAAQS) and Regional Haze Regulations, November 2005, the only pollutants reported are 

Nitrogen Oxides (NOx) and Volatile Organic Compounds (VOC) and emissions are summed 

as tons/average summer day for the year 2011. Appendix V contains the Emission Inventory 

for DeSoto County, Mississippi. 

SOURCES AFFECTED BY THE REVISION:

This SIP revision potentially affects all sources and practices subject to air pollution control 

regulations in Mississippi.

DEADLINE FOR COMMENTS: OCTOBER 2, 2014 

PLEASE TAKE NOTE that the Mississippi Commission on Environmental Quality 

(“Commission”) is considering adopting a State Implementation Plan Revision for Purposes of 

an Emissions Inventory for the Ozone Nonattainment Area of DeSoto County, Mississippi and 

adopting new air pollution control regulations for areas in Mississippi designated as 

Nonattainment for Federal National Ambient Air Quality Standards (NAAQS). The new 

proposed regulations will be entitled 11 Mississippi Administrative Code, Part 2, Chapter 11, 

“Regulations for Ambient Air Quality Non-Attainment Areas” and will be applicable statewide. 

I. Substance of the proposed action: 

On July 22, 2012, the United States Environmental Protection Agency (EPA) designated 

a portion of DeSoto County, Mississippi to be included as a part of the Memphis, 

Tennessee – Mississippi – Arkansas (TN-MS-AR) Marginal Ozone Non-Attainment 

Area. Therefore, the Mississippi Department of Environmental Quality (MDEQ) is 

required by the Clean Air Act (CAA) to implement requirements for certain air emission 

sources in Non-Attainment Areas to submit an Emissions Statement annually. The 

Department is also required to submit an Emissions Inventory of sources in the nonattainment portion of DeSoto County, Mississippi. Section 182(a)(3)(B) of the (CAA) 

requires that within two (2) years of enactment of the CAA Amendments of 1990, states 

submit to EPA a SIP submittal requiring sources in their marginal and above ozone nonattainment areas to submit annual emissions statements. CAA section 182(a)(1) requires 

that marginal and above ozone nonattainment areas submit a base year emission 

inventory of ozone precursors for the nonattainment area two(2) years after designation. 

The Department is proposing to adopt a State Implementation Plan Revision (SIP 

Revision) which includes adoption of new air pollution control regulations specifically 

for the purposes of implementing federal requirements for areas designated as nonattainment for National Ambient Air Quality Standards (NAAQS). The proposed new air 

pollution control regulations are entitled 11 Mississippi Administrative Code, Part 2, 

Chapter 11, “Regulations for Ambient Air Quality Non-Attainment Areas”. The 

regulations will be applicable to sources in DeSoto County, Mississippi as well as any 

other areas in Mississippi that may be designated non-attainment for air quality in the 

future. The proposed SIP Revision also includes the required emissions inventory for 

DeSoto County, Mississippi. 

II. Manner By Which the Public May Comment. 

Copies of the proposed SIP Revision and proposed regulations may be obtained by 

calling Mr. Keith Head at 601-961-5577 or writing to Mississippi Department of
