Inventory Comparison

- 2007/2008/2025

The 2007, 2008 and 2025 emission i nventories were evaluated to show that the 2007 emission inventory is an appropriate and representative emission inventory to use as a surrogate attainment
emission inventory for the 2008 emission inventory for the Pennsylvania portion of the Philadelphia

Wilmington PA

- NJ

- DE PM2.5 nonattainment area for the 2006 24

- hour PM2.5 National Ambient Air Quality Standard (NAAQS). The 2007 and 2025 emission inventories were d eveloped for MARAMA in a regional effort that Pennsylvania participated in to refine the emissions inventory and to compile a regional emissions inventory

. See Appendix C for detailed inventory methodology information for 2007
and 2025 inventories . Emiss ions for point, area and nonroad sectors for the 2008 emission inventory are from the 2008 National Emissions Inventory ( NEI ) Version 2 . Emissions for the highway vehicle

sector for 2008 were generated using the MOVES model. A d etailed m ethodology descri ption for the
MOVES model is available in Appendix D.

A summary of the 2007, 2008 and 2025 emission inventories is displayed in Table 1. The inventory analysis shows that the 2007 emission inventory is comparable to the 2008 emission inventory for the Pennsylvania portion of the Philadelphia PM2.5 nonattainment area. PM2.5, SO2, NO x and NH3 are lower in 2008 by 2.2%, 15.5%, 11.1% and 4.4%, respectively. VOC emissions are higher in 2008 by 1.9%.

A comparison of the MARAMA 2007 inventory to the MARAMA 2025 inventory shows a decrease in PM2.5, SO2, NOx, VOC and NH3 emissions from 2007 to 2025. A comparison of the 2008 NEI to the MARAMA 2025 inventory also shows decreases in PM2.5, SO2, NOx and VOC. In the 2008 to 2025 inventory comparison, NH3 emissio ns increase slightly by 1.3%, which is not a concern because ammonia emission are very small compared with other pollutant emissions.

The inventory analysis shows that a decreasing trend in emissions is anticipated through 2025 from a 2007 inventory base year and from a 2008 inventory base year. Therefore, both the 2007 and 2008 emission inventories satisfy the maintenance demonst ration criteria provided in EPA guidance that a state may demonstrate maintenance of a NAAQS by showing that future projected emissions are less than or equal to the attainment year. ((See, EPA, “Procedures for Processing Requests to Redesignate Areas to Attainment,” John Calcagni (September 4, 1992) (Calcagni Memo)).Table 1 Comparison of 2007/2008/2025 Emission Invent ories
