Atlantic City, PA-NJ-BE 8-Hour Ozone Nonattainment Areas; Public

Hearing

[40 Pa.B. 756]

jSaturday, February 6, 2010]

Particulate matter (PM) includes both solid and liquid particles suspended in the air. Fine

particle pollution describes particulate matter that is less than or equal to 2.5 micrometers in

diameter (PM25).PM25 concentrations above the Federal health-based standard pose a

serious human health threat. Health studies have shown a significant association between

exposure to fine particles and premature death from heart or lung disease. In 1997, the U.S.Environmental Protection Agency (EPA) established an annual primary (health-based) andsecondary (welfare-based) PM25 standard of 15.0 micrograms per cubic meter (jag/m 3),

based on the 3-year average of annual mean PM25 concentrations. The EPA alsoestablished a primary and secondary 24-hour standard of 65 jig/m 3determined by the 3-

year average ofthe 98th percentile of 24-hour concentrations. Implementation of the

standard was delayed due to legal challenges. In the Commonwealth of Pennsylvania, EPA

designated eight areas comprised of all or parts of 21 counties as PM25 nonattainment areasfor the annual standard. For each nonattainment area, the Commonwealth is required todevelop a State Implementation Plan (SIP) revision that demonstrates how the area willattain the standard by the prescribed attainment date, April 5, 2010.

The Department of Environmental Protection (Department) is seeking public comment on

the SIP revision for the Philadelphia-Wilmington, PA-NJ-DE PM25 Nonattainment Area

(Philadelphia PM25 Area.) The proposed SIP revision contains information on PM25 trendsand emissions to demonstrate that the Philadelphia PM25 Area meets all requirements

necessary for an approvable SIP revision. The proposed SIP revision demonstrates how thearea will attain the PM25 standard by April 5, 2010, by presenting evidence from air quality

modeling, emission trends, regional pollutant transport impacts and emission reductionsthrough State and Federal control measures. In addition, the proposed revision to the SIP

contains the base-year 2002 emissions inventory, mobile source emission budgets for

purposes of transportation conformity and a contingency plan to bring the area back intoattainment should future violations of the standard occur. After consideration of commentsreceived, the SIP revision will be finalized and submitted to the EPA for approval.

In addition, the Department is seeking public comment on a proposed SIP revision to

correct the Stationary Point Source Annual Emissions included in the 2002 Base-Year
