Mississippi NAA SIP, Final Adopted November 20, 2014 2 1.57 Introduction: State Implementation Plan (SIP) Revision for Purposes of the Emissions Statement and Emissions Inventory for the Ozone Nonattainment Area of DeSoto County, Mississippi.

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 ground-level 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.

Mississippi NAA SIP, Final Adopted November 20, 2014 4 MISSISSIPPI COMMISSION ON ENVIRONMENTAL QUALITY NOTICE OF PUBLIC HEARING

PUBLIC NOTICE START DATE: SEPTEMBER 2, 2014 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 Nonattainment 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, – Mississippi – (TN-MS-AR) Marginal Ozone Nonattainment 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 Nonattainment 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 Nonattainment Areas”. The regulations will be applicable to sources in DeSoto County, Mississippi as well as any other areas in Mississippi 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.

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 Environmental Quality, Air Division, P.O.

Emissions Inventory for DeSoto County, Mississippi

Mississippi NAA SIP, Final Adopted November 20, 2014 19 INTRODUCTION The following contains emission summary tables for DeSoto County, MS, which is part of the Memphis Ozone Nonattainment Area. The inventory data is for calendar year.

BASELINE YEAR (2011) INVENTORIES 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.

Table 1: 2011 Average Summer Day Emissions for DeSoto County, MS 2011 Summer Day 2011 Summer Day Sector NOX Emissions VOC Emissions (tons/day) (tons/day) Point 1.533 0.817 Nonpoint 1.267 7.062 (excluding Biogenic) Nonroad Mobile 2.054 1.658 Onroad Mobile 8.969 5.178 TOTAL 13.847 14.734

Mississippi NAA SIP, Final Adopted November 20, 2014 20 2011 POINT SOURCE INVENTORY The development of the point source inventory by the Department began with the collection of actual 2011 process data and emission estimates from all Title V stationary sources that are required to submit inventory data according to the Air Emissions Reporting Rule (AERR). Each 2011 inventory received was reviewed by the Department’s staff to ensure that correct procedures were followed and appropriate emission factors, such as stack testing or AP-42 emission factors, were used in developing the 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 fill” pollutants or sources not provided by agencies.

To estimate the average summer day emissions for industrial point sources, the MDEQ used monthly throughput percentages provided by the facilities. The 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 percent of activity for 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 estimated 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.

Mississippi NAA SIP, Final Adopted November 20, 2014 24 2011 NONPOINT EMISSION INVENTORY

Nonpoint sources include emissions estimates from 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 such as commercial bakeries, product storage and transport distribution such as gasoline, stationary source fuel combustion 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 using established emissions factors provided by EPA. Activity data adjustments are made to address some issues when estimating emissions. These issues include coal data, nonroad mobile source consumption, non-fuel use, and point source adjustment. These adjustments are made 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, July, August and September) and dividing the sum by the number of 2011 summer days (153 days).

Mississippi NAA SIP, Final Adopted November 20, 2014 28 2011 NONROAD MOBILE SOURCE EMISSIONS

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

Aircraft engine emissions occurring during landing & takeoff operations and the ground support equipment & auxiliary power units (APU) associated with the aircraft are included in the point source category at individual airports. In-flight aircraft emissions, locomotive emissions outside of the rail yards, and commercial marine vessel 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 Mobile Inventory Model (NMIM). Locomotives and commercial marine vessels are estimated for the 2011 NEI by the NONROAD model even though the emission sources are not included in the Non-road source category. Average summer day emissions were calculated by summing the monthly 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 Nonattainment Area. The inventory data is for calendar year 2011. The DeSoto County emissions 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 Nonattainment 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 trucks, and buses. The sectors include emissions from parking areas as well as emissions while the vehicles are moving.
