2003 Air Quality Management Plan (AQMP)

2003 Air Quality Management Plan

The South Coast Air Quality Management District Governing Board adopted the 2003 Air Quality Management Plan (AQMP) on August 1, 2003.  The 2003 AQMP updates the attainment demonstration for the federal standards for ozone and particulate matter (PM10); replaces the 1997 attainment demonstration for the federal carbon monoxide (CO) standard and provides a basis for a maintenance plan for CO for the future; and updates the maintenance plan for the federal nitrogen dioxide (NO2) standard that the South Coast Air Basin (Basin) has met since 1992.

This revision to the AQMP also addresses several state and federal planning requirements and incorporates significant new scientific data, primarily in the form of updated emissions inventories, ambient measurements, new meteorological episodes and new air quality modeling tools.  The 2003 AQMP is consistent with and builds upon the approaches taken in the 1997 AQMP and the 1999 Amendments to the Ozone SIP for the South Coast Air Basin for the attainment of the federal ozone air quality standard.  However, this revision points to the urgent need for additional emission reductions (beyond those incorporated in the 1997/99 Plan) from all sources, specifically those under the jurisdiction of the California Air Resources Board and the U.S. Environmental Protection Agency which account for approximately 80 percent of the ozone precursor emissions in the Basin.

Chapter 5, “Future Air Quality,” describes the modeling approach used in the AQMP and summarizes the Basin’s future air quality projections with and without controls.

6 Clean Air Act Requirements
  Chapter 6, “Clean Air Act Requirements,” discusses specific federal and state requirements as they pertain to the 2003 AQMP and demonstrates compliance with the requirements.
7 Implementation
 

Chapter 7, “Implementation,” presents the implementation schedule of the various control measures and delineates each agency’s area of responsibility.

8 Future Air Quality – Desert Nonattainment Area
 

Chapter 8, “Future Air Quality - Desert Nonattainment Areas,” demonstrates compliance with the Federal Clean Air Act requirements pertaining to the Coachella Valley.

9 Contingency Measures
  Chapter 9, “Contingency Measures,” presents contingency measures as required by the federal CAA .
10 Looking Beyond Current Requirements
  Chapter 10, “Looking Beyond Current Requirements”, discusses uncertainties associated with the technical analysis provided in the AQMP; and presents a preliminary analysis regarding the new Federal PM2.5 and 8-hour ozone ambient air quality standards.
