SIP Content & Results Combination emission reduction
measures Local point, mobile, & nonroad reductions Significant regional reductions of SO2 & NOX
Attainment demonstrated by 2009 using regional modeling Results consist with other modeling efforts

Conclusions DC area has a more than adequate
monitoring network Entire area currently monitoring
attainment with annual standard No EPA defined “hotspots” exist Model predicted attainment of all
standards by 2009 Complete & fully approvable SIP
Local Area Analysis (LAA) Perceived local “hotspot” at PRGS Onsite monitoring underway No monitored evidence of hotspot exists LAA not required by EPA guidance Comprehensive permit for PRGS in
process Bottom line – permit the appropriate
mechanism to resolve any local issues
Mirant PRGS Monitoring PM2.5 FRM PM2.5 Continuous PM2.5 EBAM Two SO2 Monitors Results to date
consistent with attainment (2007) Annual: 13.5 Daily: 32
