Collin County Attainment Demonstration SIP Revision and Agreed Order

On May 30, 2012, the commission will consider for adoption the executive director's recommendation regarding the Collin County Attainment Demonstration for the 2008 National Ambient Air Quality Standard (NAAQS) for lead and the Agreed Order between the TCEQ and Exide Technologies (Exide). The state implementation plan (SIP) revision contains a reasonably available control measure and a reasonably available control technology analysis, demonstration of attainment through air dispersion modeling, a control strategy demonstration, an emissions inventory, a demonstration of reasonable further progress, and contingency measures. The Agreed Order will make the control strategies and contingency measures included in the Collin County Attainment Demonstration SIP Revision legally enforceable.

Comments and transcript of public hearing

The Collin County Attainment Demonstration SIP revision is scheduled for adoption on December 7, 2011. The SIP revision is due to the EPA June 30, 2012.

On June 22, 2011, the commission approved proposal of the Collin County Attainment Demonstration SIP Revision for the 2008 Lead NAAQS and the associated Agreed Order between the TCEQ and Exide Technologies. The SIP revision provides air dispersion modeling to demonstrate that the nonattainment area will attain the 2008 lead NAAQS by the December 31, 2015, attainment date, and includes a reasonably available control technology (RACT) analysis, a reasonably available control measures (RACM) analysis, a reasonable further progress (RFP) demonstration, an emissions inventory, and a contingency plan. To ensure compliance with the 2008 lead NAAQS, the Agreed Order proposal was approved concurrently with the SIP revision. The Agreed Order provides enforceable measures to reduce emissions necessary for the Collin County lead nonattainment area to attain the 2008 lead NAAQS by the attainment date, and contains contingency measures designed to ensure continued compliance with the standard.

EPA Designates Part of Collin County as a Lead Nonattainment Area

In the November 22, 2010 Federal Register, the United States Environmental Protection Agency (EPA) published the determination that an area in Collin County, Texas surrounding Exide Technologies battery recycling plant was not meeting the National Ambient Air Quality Standard (NAAQS) for lead. In October 2008, the EPA lowered the standard tenfold from its 1978 level of 1.5 micrograms per cubic meter to 0.15 micrograms per cubic meter.

Texas’ lead attainment demonstration SIP will be due to the EPA on June 30, 2012, and Collin County must attain the new lead standard before the December 31, 2015, attainment date.

EPA’s Proposed Designation Letter and Revised Boundary Recommendation

On June 14, 2010 the EPA sent a letter notifying the state that the EPA intends to designate the portion of Collin County recommended by Texas as nonattainment for the 2008 NAAQS for lead.

On August 17, 2010, the TCEQ submitted a comment to the EPA in support of the designation boundary and correcting references to certain monitoring data.

TCEQ comment on EPA responses, August 17, 2010

On October 13, 2010, the governor submitted a revised boundary recommendation to the EPA. The revised recommendation takes in to account a permit alteration that reduces the permitted allowable emission rate contained in Exide Technologies’ air permit no. 1147A. This revised recommendation uses the same methodology as the original recommendation, but incorporates reduced permit limits in the dispersion modeling, thereby reducing the size of the nonattainment area.

2008 Lead-Standard Attainment Designation and Boundary Recommendation

On August 26, 2009, the commission approved a recommendation concerning designations under the EPA’s 2008 NAAQS for lead. The 2008 standard, along with guidance for determining nonattainment area boundaries, was published in the Federal Register on November 12, 2008. The 2008 standard strengthens the original 1978 lead standard tenfold, dropping it from 1.5 to 0.15 micrograms per cubic meter.

On October 14, 2009, Texas Governor Rick Perry submitted the state’s recommendation concerning designations and boundaries under the 2008 National Ambient Air Quality Standard (NAAQS) for lead to the U.S. Environmental Protection Agency’s Region 6 office.
