St. Louis Eight-Hour Ozone and PM 2.5 SIP
Development Process

Draft State SIP
Technical Work Group
Control Strategy Work Group
I/M Work Group

In September 2004 at East-West Gateway, the Missouri Department of Natural Resources (MoDNR) and the Illinois Environmental Protection Agency (IEPA) hosted a kickoff meeting with local stakeholders to discuss the steps involved in the preparation of the Missouri and Illinois St. Louis Area State Implementation Plans (SIPs) for both the eight-hour ozone and PM 2.5 standards. The 8-hour ozone SIPs are to be submitted to the U.S. Environmental Protection Agency (USEPA) by June 15, 2007. The St. Louis region is to be in attainment of the eight-hour ozone standard by June 2010 which means the controls have to be in place in 2009, before the start of the ozone season in April 2010. The PM 2.5 SIPs are due to USEPA in April 2008 and the attainment date is 2010. 

Two technical work groups, the Control Strategy Work Group and the Modeling and Data Analysis (Technical) Work Group, were established. They will assist the states in identifying and evaluating emission control strategies and in the preparation of modeling protocol, selection of a photochemical model and performing model runs.

The Air Quality Advisory Committee (AQAC) of East-West Gateway has traditionally focused on transportation planning, identification of Transportation Control Measures (TCMs) and transportation air quality conformity determination. However in the 8-hour ozone SIP development process, the AQAC will also have a role in the identification of control strategies and information sharing. Both work groups will report and inform the AQAC on their respective activities and progress to date. The AQAC will act as a public forum and sounding board for the various control strategies developed by the two work groups.

Draft Illinois and Missouri 8-Hour Ozone State Implementation Plans

The Illinois Environmental Protection Agency (Illinois EPA) will hold a public hearing on May 3, 2007 for the purpose of gathering public comment on the draft ozone Attainment Demonstration and the draft motor vehicle emissions budgets. The Attainment Demonstration contains the State's plan for attaining the 8-hour ozone National Ambient Air Quality Standard (NAAQS) in Jersey, Madison, Monroe, and St. Clair counties. Illinois EPA is proposing to submit the Attainment Demonstration and the draft motor vehicle emissions budgets to the U.S. EPA as State Implementation Plan (SIP) revisions to meet the requirements of the federal Clean Air Act (CAA) to achieve the NAAQS for 8-hour ozone. The hearing will be at 10:30 AM in the Regional Conference Room at the Illinois Department of Transportation - District 8 Offices, 1102 Eastport Plaza Drive, Collinsville.  The Public Notice, the draft Ozone Attainment Demonstration for the Metro-East Non-Attainment Area and related documents, including how to submit written comments, are available online at http://www.epa.state.il.us/public -notices/general-notices.html#metro-east-ozone

The Missouri Air Conservation Commission will hold a public hearing during their meeting on April 26, 2007 for the purpose of gathering public comment on the proposed 2007 Revision of the SIP for the St. Louis 8-Hour Ozone Non-attainment Area. This area includes the City of St. Louis, St. Louis, St. Charles, Jefferson and Franklin counties. The meeting of the Missouri Air Conservation Commission starts at 9 AM in the Roaring River Conference Room, Lower Level, Elm Street Conference Center, 1738 East Elm Street in Jefferson City. Comments will be accepted on this plan action through close of business May 3. The document is available at http://www.dnr.mo.gov/env/apcp/stateplanrevisions.htm.

 

Technical Work Group

The Technical Work Group is composed of representatives from the state air agencies, U.S. Environmental Protection Agency, affected businesses, business groups, East-West Gateway and other interested organizations and individuals. The group has been working since last fall on preparing model protocol, assembling meteorological information, finalizing the 2002 base year emissions inventory and selecting (and validating) photochemical grid model to be used in SIP development. Modeling centers at MoDNR, IEPA, Ameren and USEPA Region 7 are evaluating meteorological and photochemical models and will perform model runs. The model domain encompasses all of the U.S. east of the Rocky Mountains. Four 10-day episodes in 2002 have been selected, three in summer and one in winter which will be used to quality assure of the various model preprocessors/components. MoDNR has hired a consultant to help resolved various emissions inventory issues and to assist the work group in merging emissions inventories from the Midwest Regional Planning Organization (MRPO) and the Central States Regional Air Partnership (CENRAP). MRPO and CENRAP are multi-state organizations working on regional haze and related air quality issues. 

When all of the model preprocessors and model have been validated, the group will begin to run the photochemical model with control strategies which are on the books and see if it shows that the area can reach attainment. The next run would include control strategies which will likely happen before 2009 such as the Clean Air Interstate Rule, the oxides of nitrogen (NO x) SIP call and low sulfur fuels. If these model runs which will incorporate these control strategies do not show the area in attainment, then the states will have to consider additional control strategies.

Control Strategy Work Group

The Control Strategy Work Group is composed of representatives from the state air agencies, USEPA, health organizations, environmental groups, East-West Gateway, business groups, state transportation agency and other interested organizations and individuals. The mission of the work group is to develop a set of emissions control strategies which will help the area reach attainment of the eight-hour ozone and the PM 2.5 standards. Controls currently on the books, potential federal actions and possible alternatives will all be considered. The work group and the consultant are researching potential control strategies and associated emissions reductions and cost effectiveness. In addition, how the public is affected by a control strategy, the political feasibility and the time needed to implement will also be considered. All of this information is to be placed in a decision matrix. A special subcommittee is examining voluntary control measures that could be taken in the short term to reduce emissions. These voluntary controls typically do not require special rule-making or lengthy regulatory process.

MoDNR has a web site with additional information on the eight-hour ozone and PM 2.5 SIP development process. The site's address is:

Inspection and Maintenance (I/M) Work Group

Because of St. Louis' classification as a moderate eight-hour ozone standard non-attainment area, Federal rules will region that the St. Louis area have an I/M program post 2007. In Missouri, the current I/M contract expires in August 2007. The purpose of this Work Group is to explore options for a post 2007 I/M program in Missouri. Therefore, this effort is not focused on redesigning the current program but directed at developing a new and improved I/M program. The Missouri Department of Natural Resources wants the new I/M program to reflect the needs of the stakeholders and balance environmental gains with customer convenience.  Throughout the I/M Work Group process, both the majority and minority (non-majority) views will be noted and documented. At the first meeting there were a number of federal and state presentations which provided a foundation/background and introduced the stakeholders to the I/M design concepts, so that all have a common understanding and a starting point for future discussions and meetings.
