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 de signation as nonattainment. Specifically it provides that the emissions statement must: “...r equire 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 Ad ministrator may prescrib e (or an equivalent alternative developed by the state), for clas ses or categories of sources, showing the actual emissions of oxides of nitrogen and vol atile organic compounds from that source.
The first such statement shall be submitted with in 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 ground-le vel ozone. The new regulations are 11 Mississippi Administrative C ode, Part 2, Chapter 11, Regulations for Ambient Air Quality Nonattainment Areas. The regulation s 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 Margin al and above ozone nonattainment areas submit a base year emissions inventory for the nonattainment area 2 years after designation as nonattainment. The emissions ar e reported as tons/average summer day of pollutant. In accordance with the requirements of EPA’s Emissions Inventory Guidance for Implementation of Ozone and Particul ate 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.Mississippi NAA SIP, Final Adopted November 20, 2014 4 1.58 Notification of Public Comment Period for the SIP Revision.

PUBLIC NOTICE START DATE: SEPTEMBER 2, 2014 DEADLINE FOR COMMENTS: OCTOBER 2, 2014

PLEASE TAKE NOTE that the Mississippi Commission on Envi ronmental Quality (“Commission”) is considering adopting a State Implementation Plan Revision for Purposes of an Emissions Inventory for the Ozone Nonattain ment Area of DeSoto County, Mississippi and adopting new air pollution control regulations for areas in Missi ssippi designated as Nonattainment for Federal National Ambient Air Quality Standards (NAAQS). The new proposed regulations will be entitled 11 Mississi ppi Administrative Code, Part 2, Chapter 11, “Regulations for Ambient Air Quality Nonattainme nt 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, Mississi ppi to be included as a part of the Memphis, Tennessee – Mississippi – Arkansas (TN-MS-AR) Marginal Ozone Nonattainment Area. Therefore, the Mississippi Department of Environmental Qua lity (MDEQ) is required by the Clean Air Act (CAA) to implement requirements for certain air emission sources in Nonattainment Areas to submit an Emissions Statement annually. The Department is also required to submit an Emissions Inventory of sources in the nonattai nment portion of DeSoto County, Mississippi. Section 182(a)(3)(B) of the (CAA) requires that w ithin 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 cont rol regulations specifical ly for the purposes of implementing federal requirements for areas desi gnated as nonattainment for National Ambient Air Quality Standards (NAAQS). The proposed new air pollution c ontrol regulation s are entitled 11 Mississippi Administrative Code, Part 2, Chap ter 11, “Regulations for Ambient Air Quality Nonattainment Areas”. The regulations will be applicable to sources in DeSoto County, Mississippi as well as any other areas in Mississip pi that may be designated nonattainment 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.

BASELINE YEAR (2011) INVENTORIES The emissions are reported as tons/average su mmer day of pollutant. In accordance with the requirements of EPA’s Emissions Inventory Guidance for Implementation of Ozone and Particulate Matter National Ambient Air Qu ality Standards (NAAQ S) and Regional Haze Regulations, November 2005 the only pollutant s reported are Nitrogen Oxides (NOx) and Volatile Organic Compounds (VOC) and emissions are summed as tons/average summer day for the year 2011.

Total 0.574 25.280Mississippi NAA SIP, Final Adopted November 20, 2014 21 2011 POINT SOURCE INVENTORY The development of the point sour ce inventory by the Department began with the collection of actual 2011 process data and emission estimates fr om all Title V stationary sources that are required to submit inventory data according to th e Air Emissions Reporting Rule (AERR). Each 2011 inventory received was reviewed by the De partment’s staff to ensure that correct procedures were followed and appropriate emissi on factors, such as st ack testing or AP-42 emission factors, were used in developing th e inventory. The Department submitted the 2011 point data to the EPA as part of the 2011 NEI effort. The EPA did make some amendments to the Department’s data, but primarily to “gap fi ll” pollutants or sources not provided by agencies.

To estimate the average summer day emissions fo r industrial point sources, the MDEQ used monthly throughput percentages provided by the f acilities. The airport point source inventory was developed from data provided by the EPA. It was assumed that these sources operated at a constant rate throughout all months of the year (8.333% activity for each month). If each month of the year contributed 8.333% of the activity, the pe rcent of activity fo r the 5 ozone season months would be 41.66%. Since there are 153 days in the 2011 ozone season, the 41.66% can be divided by 153 to get an estimate of activity for an average ozone season day. This gives a result of 0.272% activity for each day. The estimat ed ratio of 0.00272 was multiplied by the annual emissions to estimate the average summer day emissions. The data was reviewed by the Department’s staff and updated as necessary.

Grand Total 0.81664672Mississippi NAA SIP, Final Adopted November 20, 2014 25 2011 NONPOINT EMISSION INVENTORY

Nonpoint sources include emissions estimates fro m sources that are either too small or too numerous to be considered point sources which are calculated and recorded on the county-level. Major categories for nonpoint sources include: Solvent use such as small surface coating operations, light industrial/commercial sources su ch as commercial bakeries, product storage and transport distribution such as gaso line, stationary source fuel com bustion such as residential fuel combustion, waste management such as landfills, agriculture such as feedlots and crop burning, and miscellaneous area sources such as unpaved roads.

Emissions from nonpoint sources are calculated us ing established emissions factors provided by EPA. Activity data adjustments are made to a ddress some issues when estimating emissions. These issues include coal data, nonroad mobile source consumption, non-fuel use, and point source adjustment. These adjustments are ma de to prevent emissions from being double counted. Average summer day emissions were calculated by summing the monthly emissions for the five summer months (May, June, Jul y, August and September) and dividing the sum by the number of 2011 summer days (153 days).

Non-road sources are vehicles that normally operate off-road/off-highway and not on-road/onhighway. Non-road emissions source category in clude: agricultural equipment, construction and mining equipment, lawn and garden equipment, off-road recreational equipment, and drilling rigs. The nonroad mobile emissions are deri ved from the 2011 National Emissions Inventory (NEI).

Aircraft engine emissions o ccurring during landing & takeoff operations and the ground support equipment & auxiliary power units (APU) associated with the airc raft are included in the point source category at individual airports. In-flight aircraft emissions, locomotive emissions outside of the rail yards, and commercial marine ve ssel emissions (both underway and port emissions) are included in the Non-Point source category.

The NEI Onroad and Nonroad source categories contain mobile sources which are estimated by EPA for the 2011 NEI by the MOVES2010b and NONROAD models, respectively.
NONROAD model was run within the National M obile Inventory Model (NMIM). Locomotives
and commercial marine vessels are estimat ed for the 2011 NEI by the NONROAD model even though the emission sources are not included in th e Non-road source category. Average summer day emissions were calculated by summing the m onthly emissions for the five summer months (May, June, July, August and September) and dividing the sum by the number of 2011 summer days (153 days).

The following section contains onroad mobile inventory documentation for the portion of DeSoto County that is within Memphis Ozone N onattainment Area. The inventory data is for calendar year 2011. The DeSoto County emissi ons inventory was developed by the Memphis Urban Area Metropolitan Planning Organization (MPO), with input from MDEQ and others, as part of the 2040 Desoto County Nonattain ment Area Moves Air Quality Conformity Demonstration (March 2013). To calculate the average summer day emissions, the MPO modeled weekday emissions in July.

Onroad mobile sources are sources of pollution caused by vehicles transporting goods or people on public roadways. This includes passenger cars, motorcycles, minivans, sport-utility vehicles, light-duty trucks, heavy-duty tr ucks, and buses. The sectors include emissions from parking
areas as well as emissions while the vehicles are moving.
