1.49 Introduction: State Implementation Plan (S IP) Revision Regarding Requirements of the Federal National Ambient Air Quality Standard for Fine Particulate Matter (PM2.5) As It Pertains to the Prevention of Significant Deterioration of Air Quality (PSD).

The regulation amendments involve amendments to “Regulations for the Prevention of Significant Deterioration of Ai r Quality”, APC-S-5 to adopt, by reference, updated relevant portions of federal regulations as prom ulgated in 40 CFR Parts 51.166, 52.21, and 52.22 in order to make the state Prevention of Signi ficant Deterioration of Air Quality permitting program consistent with the federal requirements. Specifically, the amendments incorporate federal provisions relating to implementing the New Source Review (NSR) program for fine particulate matter that was promulgated by EPA on May 16, 2008, and the PM 2.5 

# Increments, Significant Impact Levels (SILs) and Si gnificant Monitoring Concentration (SMC) promulgated on October 20, 2010. Amendments to APC-S-5 were adopted on April 28, 2011, by the Mississippi Commission on Environm ental Quality. The amendments will become state effective June 2, 2011 which is 30 days after final fili ng with the State of Mississippi Secretary of State which occurred May 3, 2011

EPA’s 2008 NSR PM 2.5 

# Implementation Rule (73 FR 28321) identifies nitrogen oxides (NOx) as a presumed precursor to PM 2.5 

# in all attainment and unclassifiable areas, unless the State demonstrates to the Administrator's satisfaction or EPA demonstrates that emissions of NOx from sources in a specific area are not a significant contributor to that area's ambient
PM 2.5 

# concentrations. Appendix C-23 of the pr oposed SIP revision contains a technical demonstration which shows that NOx from sources in the state do not significantly contribute to PM 2.5 

# ambient air concentrations in Missi ssippi. Mississippi is submitting this technical demonstration to U.S. EPA for approval as part of the PM 2.5 

# 5 NSR Implementation SIP package. Mississippi is adopting the PM 2.5 

# provisions into APC-S-5 by reference. Depending upon the final action fr om US EPA, we will address NOx as a PM 2.5 

# precursor as follows:

1. Until such a time where EPA takes action on the demonstration or upon plan disapproval, NOx will be considered as a precursor for PM 2.5 

# in Mississippi.

2. Upon EPA approval of this demonstration, NOx will not be considered as a precursor for PM PM 2.5 

# in Mississippi.

There were no comments received at the pub lic hearing held April 21, 2011. The US Environmental Agency submitted comments re garded the SIP provision. One comment requested that that Mississippi consider re moving the grandfathering provisions for PM2.5 from our adoption by reference, since EPA will very shortly repeal this provision. The Commission did include a provision in the approved regulation which excludes the grandfathering provision for PM2.5. EPA also co mmented that the tec hnical demonstration for NOx insignificance as a precursor for PM 2.5 was still under review and has not been approved. Since the technical demonstration has not been approved, NOx is considered a precursor for PM2.5 at this time. No other comments were received.

MISSISSIPPI COMMISSION ON ENVIRONMENTAL QUALITY
NOTICE OF PROPOSED RULEMAKING
NOTICE OF PUBLIC HEARING PUBLIC NOTICE START DATE: MARCH 22, 2011

PLEASE TAKE NOTE that the Mississippi Commi ssion on Environmental Quality (“Commission”) is considering a Revision to the State Implementa tion Plan for Air Pollution Control (SIP Revision) and amendments to state air pollution contro l regulations. The proposed SIP Revision and regulation amendments will be applicable statewide.

I. The proposed SIP Revision and amendments to state air pollution contro l regulations involve amendments to “Regulations fo r the Prevention of Significant Deterioration of Air Quality”, APC-S-5 to adopt, by reference, updated rele vant portions of federal regulations as promulgated in 40 CFR Parts 51.166, 52.21, and 52.22 to make the state Prevention of Significant Deterioration of Air Quality perm itting program consistent with the federal requirements. Specifically, the proposed ame ndments will incorporate federal provisions relating to implementing the New Source Review (NSR) program for fi ne particulate matter (PM2.5) that was promulgated by EPA on May 16, 2008 and the PM2.5 Increments, Significant Impact Levels (SILs) and Si gnificant Monitoring Concentration (SMC) promulgated on October 20, 2010.

EPA’s 2008 NSR PM2.5 Implementation Rule (73 FR 28321) identifies nitrogen oxides (NOx) as a presumed precursor to PM2.5 in all attainment and unclassifiable areas, unless the State demonstrates to the Administrato r's satisfaction or EPA demonstrates that emissions of NOx from sources in a specific area are not a significant contributor to that area's ambient PM2.5 concentrations. The draft SIP revision contains a technical demonstration which shows that NOx from sources in the state do not significantly contribute to PM2.5 ambient air concentrations in Mississippi. Mississippi proposes to submit this technical demonstration to U. S. EPA for approval as part of the PM2.5 NSR Implementation SIP package. Mississi ppi is proposing to adopt the PM2.5 provisions into APC-S-5 by reference. Depending upon the final action from US EPA, we are proposing to address NOx as a PM2.5 precursor as follows:

1. Until such a time where EPA takes action on the demonstration or upon plan disapproval, NOx will be considered as a precursor for PM2.5 in Mississippi. 2. Upon EPA approval of this demonstration, NOx will not be considered as a precursor for PM2.5 in Mississippi.

Mississippi is specifically soliciting comment s on the appropriateness of including or excluding NOx as a PM2.5 precursor for PSD purposes.

II. Manner By Which the Public May Comment.

Copies of the proposed amendments to the re ferenced regulations ma y be obtained by calling Ms. Maya Rao at 601-961-5242 or Mr. Conni e Simmons at 601-961-5165 or writing to Mississippi Department of Environmental Quality, Air Division, P.O.

Insignificance of Nitrogen Oxides emissions to PM2.5 PSD analysis

In the Implementation of the New Source Review (NSR) Program for Particulate Matter Less than 2.5 Micrometers (PM 2.5 

# ) published in the Federal Register on May 16, 2008, nitrogen oxides are presumed to be precursors to PM 2.5 

# unless the State demonstrates to the Administrator’s satisfaction or EPA demonstrates that emissions of nitrogen oxides for sources in a specific area are not a significant contributor to that area’s ambient PM 2.5 

# concentrations. Mississippi provides the information in following to demonstrate that NOx from the major sources in Mississippi is not a significant contributor to ambient PM 2.5 

# concentrations and request a de termination that NOx is not a significant contributor.

The preamble to this rule recognizes that particulate nitrates, the species that NOx would contribute, varies across the country and would be much le ss in the southeast. The preambles states “ Based on a review of speciated monitoring data analyses, it is apparent that nitrate concentrations vary significantly across the country. For example, in some southeastern locations, annual average nitrate levels are in the range of 6 to 8 percent of total PM 2.5 

# mass, whereas nitrate comprises 40 percent or more of PM 2.5 

# mass in certain California locations. Nitrate formation is favored by the availability of ammonia, low temp eratures, and high relative humidity. It is also dependent upon the relative degree of nearby SO2 emissions because ammonia reacts preferentially with SO2 over
NOx .” Mississippi submits conditions in the state are such that the formation of particulate nitrates is impaired and makes NOx insignificant in its contribution to PM 2.5 

# . Mississippi is among the most southern states in the nation with wintertime temp eratures moderated by the Gulf of Mexico. The ambient concentrations of PM 2.5 

# are typically lower in the winter when nitrates can be a greater component of PM 2.5 

# . Particulate species analysis, regional modeling studies and emission inventory data will be presented for this demonstration.

Particulate Species Analysis

Quarterly average speciated mass values from Jackson and Gulfport Speciated Trend Network monitors are illustrated in Figures 1-4. PM 2.5 

# measurements are separated into several components: ammonium (NH 4 

# ), nitrate (NO 3 

# ), sulfate (SO 4 

# ), organic carbon (OC), elemental carbon (EC), crustal, and other materials. The Jackson site was located in an inland urban area and the Gulfport site was located in a coastal urban area. At Jackson in 2005 and Gulfport in 2004, the total contribution of
NO 3 

# was 4% to the total annual average PM 2.5 

# . This was among the lowest components and lower than those cited in the preamble. In the winter, qua rter 1, when nitrates make up a slightly greater contribution, the total PM 2.5 

# mass is lower than the other quarters.

Modeling Analysis

Mississippi does not have any PM 2.5 

# non attainment areas and as such sensitivity and control strategy modeling has not been performed for any Mississippi sites. However, such modeling has been performed for neighboring states that demonstrates the impact of reducing NOx on PM 2.5 

# . As part of the Regional Haze analysis performed by the southeastern Regional Planning Organization (VISTAS), Georgia Tech performed emission se nsitivities to examine the impact of emission reductions on PM 2.5 

# concentration using CMAQv4.4_SOAmods on the VISTAS 12 km modeling domain.

Figures 5-7 show the impact of 30% reductions fo r various pollutants, incl uding NOx in the summer, winter and on an annual basis to the 2009 projected inventory for the Birmingham, Alabama area. Alabama is a neighboring state with similar meteorology to Mississippi. The sensitivities show that of the pollutants, NOx reductions have an impact of less than 0.2 microgams per cubic meter which is the least of any of the other pollutants.

Summary

The State of Mississippi has demonstrated that NOx emissions are an insignificant precursor for total annual PM 2.5 

# using evidence from monitoring, modeling, a nd inventory data. At coastal urban and inland urban sites in 2004 and 2005, the total contribution of NO 3 

# was 4% to the total annual average PM 2.5 

# . The modeling data from neighboring ar eas show that of the pollutants, NOx reductions have an impact of less than 0.2 microgram s per cubic meter which is the least of any of the other pollutants. The emission inventory data demonstrates that the relative quantity and availability of NOx emissions compared to the very small amount of nitrates in the PM 2.5 

# speciation gives further indication that NOx emitted in Mi ssissippi is not prone to nitrate formation.

DISCUSSION:

The proposed regulation amendments involve amendm ents to “Regulations for the Prevention of Significant Deterioration of Air Quality”, APC-S-5 to adopt, by reference, updated relevant portions of federal regulations as promulgated in 40 CF R Parts 51.166 and 52.21 in order to make the state Prevention of Significant Deterioration of Air Quality permitting program consistent with the federal requirements. Specifically, the amendments incor porate federal provisions relating to implementing the New Source Review (NSR) progr am for fine particulate matter that was promulgated by EPA on May 16, 2008, and the PM 2.5 

# Increments, Significant Impact Levels (SILs) and Significant Monitoring Concentration (SMC) promulgated on October 20, 2010.

EPA’s 2008 NSR PM 2.5 

# Implementation Rule (73 FR 28321) identifies nitrogen oxides (NOx) as a presumed precursor to PM 2.5 

# in all attainment and unclassifiable areas, unless the State demonstrates to the Administrator's satisfaction or EPA demonstr ates that emissions of NOx from sources in a specific area are not a significant cont ributor to that area's ambient PM 2.5 

# concentrations. Appendix 23 of the SIP revision contains a technical demonstr ation which shows that NOx from sources in the state do not significantly contribute to PM 2.5 

# ambient air concentrations in Mississippi. The demonstration is also included in Attachment 1 of the Technical Support Document. Mississippi is submitting this technical demonstration to U.S. EPA for approval as part of the PM 2.5 

# 5 NSR Implementation SIP package. Mississippi is adopting the PM 2.5 

# provisions into APC-S-5 by reference. Depending upon the final action from US EPA, we will address NOx as a PM 2.5 

# precursor as follows:

1. Until such a time where EPA takes action on the demonstration or upon plan disapproval, NOx will be considered as a precursor for PM 2.5 

# in Mississippi.

2. Upon EPA approval of this demonstration, NOx will not be considered as a precursor for PM PM 2.5 

# in Mississippi.

PURPOSE OF THE REVISION:

The purpose of the SIP revision is to incor porate by reference the requirements of the Federal National Ambient Air Quality Sta ndard (NAAQS) for Fine Particulate Matter (PM2.5) as it pertains to the Prevention of Si gnificant Deterioration of Air Quality (PSD).

SOURCES AFFECTED BY THE REVISION:

This SIP revision potentially affects all sources and practices subject to air pollution control regulations in Mississippi.

POLLUTANTS INVOLVED:

The pollutants affected by this SIP Revision are all pollutants subject to regulation.

# APC-S-5, PSD PM2.5 Final SIP Revision TSD May 13, 2011 

# 5

CHANGES IN ALLOWABLE EMISSIONS:

This SIP Revision does not include any provisions for emission limitation changes.

LOCATION/ATTAINMENT STATUS:

All areas of the state are designated attain ment for all NAAQS. The proposed SIP Revision does not change any requirements for sources lo cating in or impacting non-attainment areas.

PART D SIP/ATTAINMENT DEMONSTRATION IMPACT:

This is not applicable.

AIR QUALITY IMPACTS:

This SIP Revision will have no adverse impact on air quality.

MODELING:

No modeling is necessary for this SIP Revision.

COMPLIANCE METHODS TO BE EMPLOYED:

Compliance with the amended regulations will be achieved by air emission permits.

PUBLIC HEARING:

Public participation on the SIP Revision was achieved by a public hearing held on April 21, 2011, at 2:30 p.m. in the Commission Hearing Room (Room 104A) of the Mississippi Department of Environmental Quality Offi ce Building located at 515 E. Amite Street, Jackson, Mississippi 39201 in acco rdance with the information provided in the public notice and Mississippi Administrative Procedures Act. The notice for public hearing was published consistent with procedures approved by EPA.

The notice of public hearing was publishe d on March 22, March 29, and April 5, 2011, in daily newspapers in the cities of Gulfport, J ackson, and Tupelo in the State of Mississippi. The notice of public hearing, the proposed SIP revision, and proposed amendments to state air pollution control regulations was made available for public review in the main branches of the public libraries in the above mentione d cities and at the Mississippi Department of Environmental Quality, 515 E. Amite St., Jack son, Mississippi, 39201 and also was available on the Department’s website h ttp://www.deq.state.ms.us. The public notice was also mailed to persons on the air pollution control regulation mailing list.

TSD Attachment 3 contains a copy of the noti ce of public hearing and copies of proofs of publication of the notice of public hearing.

RESPONSE TO COMMENTS ON PROPOSED PLAN REVISION:

There were no comments received at the pub lic hearing held April 21, 2011. The US Environmental Agency submitted comments re garded the SIP provision. One comment requested that that Mississippi consider re moving the grandfathering provisions for PM2.5 from our adoption by reference, since EPA will very shortly repeal this provision. The Commission did include a provision in the approved regulation which excludes the grandfathering provision for PM2.5. EPA also co mmented that the tec hnical demonstration for NOx insignificance as a precursor for PM 2.5 was still under review and has not been approved. Since the technical demonstration has not been approved, NOx is considered a precursor for PM2.5 at this time. No othe r comments were received. TSD Attachment 4 contains a copy of EPA’s comment letter.

REGULATION CHANGES:

See TSD Attachment 2.

FINAL ADOPTION OF PLAN REVISION AND REGULATIONS:

TSD Attachment 5 contains evidence of final adoption of the SIP revision and amendments
to APC-S-5.

ADMINISTRATIVE PROCEDURES REQUIREMENTS:

Insignificance of Nitrogen Oxides emissions to PM2.5 PSD analysis

In the Implementation of the New Source Review (NSR) Program for Particulate Matter Less than 2.5 Micrometers (PM 2.5 

# ) published in the Federal Register on May 16, 2008, nitrogen oxides are presumed to be precursors to PM 2.5 

# unless the State demonstrates to the Administrator’s satisfaction or EPA demonstrates that emissions of nitrogen oxides for sources in a specific area are not a significant contributor to that area’s ambient PM 2.5 

# concentrations. Mississippi provides the information in following to demonstrate that NOx from the major sources in Mississippi is not a significant contributor to ambient PM 2.5 

# concentrations and request a de termination that NOx is not a significant contributor.

The preamble to this rule recognizes that particulate nitrates, the species that NOx would contribute, varies across the country and would be much le ss in the southeast. The preambles states “ Based on a review of speciated monitoring data analyses, it is apparent that nitrate concentrations vary significantly across the country. For example, in some southeastern locations, annual average nitrate levels are in the range of 6 to 8 percent of total PM 2.5 

# mass, whereas nitrate comprises 40 percent or more of PM 2.5 

# mass in certain California locations. Nitrate formation is favored by the availability of ammonia, low temp eratures, and high relative humidity. It is also dependent upon the relative degree of nearby SO2 emissions because ammonia reacts preferentially with SO2 over
NOx .” Mississippi submits conditions in the state are such that the formation of particulate nitrates is impaired and makes NOx insignificant in its contribution to PM 2.5 

# . Mississippi is among the most southern states in the nation with wintertime temp eratures moderated by the Gulf of Mexico. The ambient concentrations of PM 2.5 

# are typically lower in the winter when nitrates can be a greater component of PM 2.5 

# . Particulate species analysis, regional modeling studies and emission inventory data will be presented for this demonstration.

Particulate Species Analysis

Quarterly average speciated mass values from Jackson and Gulfport Speciated Trend Network monitors are illustrated in Figures 1-4. PM 2.5 

# measurements are separated into several components: ammonium (NH 4 

# ), nitrate (NO 3 

# ), sulfate (SO 4 

# ), organic carbon (OC), elemental carbon (EC), crustal, and other materials. The Jackson site was located in an inland urban area and the Gulfport site was located in a coastal urban area. At Jackson in 2005 and Gulfport in 2004, the total contribution of
NO 3 

# was 4% to the total annual average PM 2.5 

# . This was among the lowest components and lower than those cited in the preamble. In the winter, qua rter 1, when nitrates make up a slightly greater contribution, the total PM 2.5 

# mass is lower than the other quarters.

Modeling Analysis

Mississippi does not have any PM 2.5 

# non attainment areas and as such sensitivity and control strategy modeling has not been performed for any Mississippi sites. However, such modeling has been performed for neighboring states that demonstrates the impact of reducing NOx on PM 2.5 

# . As part of the Regional Haze analysis performed by the southeastern Regional Planning Organization (VISTAS), Georgia Tech performed emission se nsitivities to examine the impact of emission reductions on PM 2.5 

# concentration using CMAQv4.4_SOAmods on the VISTAS 12 km modeling domain.

Figures 5-7 show the impact of 30% reductions fo r various pollutants, incl uding NOx in the summer, winter and on an annual basis to the 2009 projected inventory for the Birmingham, Alabama area. Alabama is a neighboring state with similar meteorology to Mississippi. The sensitivities show that of the pollutants, NOx reductions have an impact of less than 0.2 microgams per cubic meter which is the least of any of the other pollutants.

MISSISSIPPI COMMISSION ON ENVIRONMENTAL QUALITY
NOTICE OF PROPOSED RULEMAKING
NOTICE OF PUBLIC HEARING PUBLIC NOTICE START DATE: MARCH 22, 2011

PLEASE TAKE NOTE that the Mississippi Commi ssion on Environmental Quality (“Commission”) is considering a Revision to the State Implementa tion Plan for Air Pollution Control (SIP Revision) and amendments to state air pollution contro l regulations. The proposed SIP Revision and regulation amendments will be applicable statewide.

I.The proposed SIP Revision and amendments to state air pollution control regulations involve amendments to “Regulations fo r the Prevention of Significant Deterioration of Air Quality”, APC-S-5 to adopt, by reference, updated rele vant portions of federal regulations as promulgated in 40 CFR Parts 51.166, 52.21, and 52.22 to make the state Prevention of Significant Deterioration of Air Quality perm itting program consistent with the federal requirements. Specifically, the proposed ame ndments will incorporate federal provisions relating to implementing the New Source Review (NSR) program for fi ne particulate matter (PM2.5) that was promulgated by EPA on May 16, 2008 and the PM2.5 Increments, Significant Impact Levels (SILs) and Si gnificant Monitoring Concentration (SMC) promulgated on October 20, 2010.

EPA’s 2008 NSR PM2.5 Implementation Rule (73 FR 28321) id entifies nitrogen oxides (NOx) as a presumed precursor to PM2.5 in all attainment and unclassifiable areas, unless the State demonstrates to the Administra tor's satisfaction or EPA demonstrates that emissions of NOx from sources in a specific area are not a signi ficant contributor to that area's ambient PM2.5 concentrations. The draft SIP revision contains a technical demonstra tion which shows that NOx from sources in the state do not significantly contribute to PM2.5 ambient air concentrations in Mississippi. Mississippi proposes to submit this techni cal demonstration to U.S. EPA for approval as part of the PM2.5 NSR Implementation SIP package. Mississippi is proposing to adopt the PM2.5 provisions into APC-S-5 by reference. Depending upon the final action from US EPA, we are proposing to address NOx as a PM2.5 precursor as follows:

1. Until such a time where EPA takes action on the demonstration or upon plan disapproval, NOx will be considered as a precursor for PM2.5 in Mississippi. 2. Upon EPA approval of this demonstration, NOx will not be considered as a precursor for PM2.5 in Mississippi.

Mississippi is specifically soliciting comment s on the appropriateness of including or excluding NOx as a PM2.5 precursor for PSD purposes.

II. Manner By Which the Public May Comment.

Copies of the proposed amendments to the re ferenced regulations ma y be obtained by calling Ms. Maya Rao at 601-961-5242 or Mr. Conni e Simmons at 601-961-5165 or writing to Mississippi Department of Environmental Quality, Air Division, P.O. Box 2261, Jackson, Mississippi 39201. For persons with internet access, a copy of the proposed SIP revision
