Transcript of Overview of Ozone and PM 2.5 in the Upper Midwest Regional Air Quality Workshop November 17, 2004.
Overview
• Current Air Quality (O3, PM2.5, and regional haze)
• Regional Planning Efforts• Schedule• Organization• Preliminary control strategy analyses
Visibility Requirements
• Section 169A of CAAA of 1977 requires “as a national goal the prevention of any future, and the remedying of any existing, impairment of visibility in Class I areas which impairment results from manmade air pollution.”
• Visibility regulations (July 1, 1999) require “reasonable progress” to achieving natural conditions by the year 2064

Model: CAMx
Domain/Grid: Eastern U.S.(36 km), Midwest (12 km)
Year: 2002 (full year) - PM/haze, 36 km
2001, 2002, 2003(summer) – O3, 12 km
2009 Base Controls• Current state/local rules to meet 1-hour ozone
requirements (e.g., motor vehicle I/M, reformulated gasoline, and NOx SIP Call)
• Heavy-duty diesel (2007) engine standard/Low sulfur fuel• Federal control programs incorporated into NONROAD
model (e.g., nonroad diesel rule), plus the evaporative Large Spark Ignition and Recreational Vehicle standards
• Federal railroad/locomotive standards• Federal commercial marine vessel engine standards• Tier II/Low sulfur fuel• Title IV for EGUs (Phases I and II)• VOC 2-, 4-, 7-, and 10-year MACT standards• Combustion turbine MACT• Industrial boiler/process heater/RICE MACT
