Approval and Promulgation of Implem entation Plans; Texas; Control of Emissions of Nitrogen Oxides From Stationary Sources in the Houston/
Galveston Ozone Nonattainment Area

AGENCY: Environmental Pr otection Agency (EPA). ACTION: Proposed approval.

------------------------------------ ----------------- ---------- --------

SUMMARY: The EPA is proposing appr oval of rules into the Texas State Implementation Plan (SIP). This rulemaking covers six separate actions. First, we are proposing to approve revisions to the Texas Nitrogen Oxides ( NOX) rules for point sources of NOX in the Houston/Galveston (H/GA) ozone nonattainment area of Texas as submitted to us by the State on December 22, 2000. These new limits for point sources of NOX in the H/GA will contribute to attainment of the 1-hour ozone National Ambient Air Quality Standard (NAAQS) in the H/GA 1-hour ozone nonatta inment area. Second, we are proposing to exclude Carbon monoxide (CO) and ammonia emission limits ancillary to the NOX standards for post combustion controls found in T itle 30 of the Texas Administrative Code (TAC), Chapter 117. Third, we are proposing to approve, by parallel processing, revisions to the Texas NOX rules for stationary diesel e ngines or stationary dual-fuel engines in the H/GA 1-hour ozone nonattainment area. Fourth, we are proposing to approve, through parallel processing, revisions made to the Texas SIP concerning compliance schedules for utility electric generation and Industrial, Commercial, and Institutional (ICI) sources in the H/GA area. Fift h, we are proposing to approve, through parallel processing, revisions made to the Texa s SIP concerning lean-burn and rich-burn engines. Sixth, we are listing, not approving, the alternate NOX emissi ons specifications and reductions that the May 30, 2001, revision to the Texas SIP contains.C:\Documents and Settings\bdeese\My Documents\Parallel Proce ssing\EPA Region 6 Parallel Proce ssing Federal Registers published 2001 to 2005.doc Bdeese,x7253 Last printed 7/24/2010 5:04:00 PM Page 3 of 15 Page 2 of 2: Texas; Control of Emissions of Nitrogen Oxides From Stationary Sources in the Houston/Galveston Ozone Nonattainment Area, TXd29

SUMMARY: The EPA is approving revisions to the Texas State Implementation Plan (SIP). This rulemaking covers five separate actions. First, we are approving revisions to the Texas Nitrogen Oxides (NOX) rules for point sources of NOX in the Houst on/Galveston (H/GA) ozone nonattainment area of Texas as submitted to us by the State on December 22, 2000. These new limits for point sources of NOX
in the H/GA will contribute to attainment of the 1-hour ozone National Ambient Air Quality Standard (NAAQS) in the H/GA 1-hour ozone nonattainment area. Second, we are approving an exclusion, from the federally-approved SIP, of carbon monoxide (CO) and ammonia emission limits ancillary to the NOX standards for post combustion controls found in Titl e 30 of the Texas Administrative Code (TAC), Chapter 117. Third, we are approving, by parallel processing, revisions to the Texas NOX rules for stationary diesel engines or sta tionary dual-fuel engine s in the H/GA 1-hour ozone nonattainment area. Fourth, we are approving, through parallel processing, revisions made to the Texas SIP concerning compliance schedules for utility electric generatio n and Industrial, Commercial, and Institutional (ICI)

Approval and Promulgation of Air Quality State Implementation Plans (SIP); Texas: Low Emission Diesel Fuel

AGENCY: Environmental Pr otection Agency (EPA). ACTION: Proposed rule.

------------------------------------ ----------------- ---------- --------

SUMMARY: The EPA is proposing to fully approve a State Implementation Plan (SIP) revision for the State of Texas establishing a Low Emission Diesel (LED) fuel for the eastern half of the State. A portion of this revision was recently proposed by the State. EPA's proposal to approve
is taken under section 110 of the Clean Air Act (the Act). This approval is also being proposed under the `` parallel processing'' provision of 40 CFR part 51. If there are significant changes between the version of the LED rule which is being `` parallel processed'' and
the version of the LED rule which Texas finally adopts, the EPA will propose a new rulemaking. If there ar e no significant changes to the

`` parallel -processed'' version, the EPA will proceed with final rulemaking on the version finally adopted by Texas and submitted to the EPA. Beginning April 1, 2005, aromatic hydrocarbon content, cetane number and sulfur content will be regulated for diesel fuel sold in 110
counties in eastern Texas for use in both motor vehicles and nonroad engines. We propose that the Texas LED fuel program requirements are necessary to achieve the National Am bient Air Quality Standard (NAAQS)
for ozone in the Houston-Galveston (HGA) ozone nonattainment area, and are therefore exempt from preempti on under Section 211(c)(4)(C) of the Clean Air Act (the Act).C:\Documents and Settings\bdeese\My Documents\Parallel Proce ssing\EPA Region 6 Parallel Proce ssing Federal Registers published 2001 to 2005.doc Bdeese,x7253 Last printed 7/24/2010 5:04:00 PM Page 5 of 15 Page 2 of 2: Texas: Low Em ission Diesel Fuel, TXd26

ACTION: Final rule.

------------------------------------ ----------------- ---------- --------

SUMMARY: The EPA is approving a St ate Implementation Plan (SIP) revision submitted by the State of Texas establishing a Low Emission Diesel (LED) fuel program for di stribution in 110 counties in the eastern and central parts of Texa s. Texas developed this fuel requirement to reduce ozone as part of the State's strategy to achievethe National Ambient Air Quality Standard (NAAQS) in the HoustonGalveston Area (HGA) nonattainment area . We are approving Texas' fuel requirement into the SIP because we found that the fuel requirement is in accordance with the requirements of the Clean Air Act (the Act) as amended in 1990 and is necessary for the nonattainment area to achieve the ozone NAAQS.

AGENCY: Environmental Pr otection Agency (EPA).
ACTION: Final Rule.

------------------------------------ ----------------- ---------- --------

SUMMARY: The EPA is approving the Texas Mass Emissions Cap and Trade (MECT) program as a revision to the Texas State Implementation Plan (SIP). The program was submitted on December 22, 2000. The MECT program will contribute to attainme nt of the 1-hour ozone National Ambient Air Quality Standard (NAAQS) in the HGA ozone nonattainment area. The EPA is approving these revisions to the Texas SIP to regulate emissions of NOX in accordance with the requirements of the Federal Clean Air Act (the Act). The EPA proposed approval of the Texas ME CT program on July 23, 2001 on the condition that Texas resolve eight issues. The St ate revised the MECT rule to ad equately address the EPA issues identified in the proposed rulemaking and submitte d these revisions to EPA as a SIP revision which EPA is approving in this action by parallel processing. Comments were received on the proposed rulemaking from Environmental Defense, Inc. on September 22, 2001, from Baker and Botts L.L.P. representing the Business Coalition for Clean Air Appeal Group on August 13, 2001, and from Reliant Energy, Inc. on August 13, 2001. The major commen ts regarded the use of credits from other trading programs for MECT compliance, inflat ion of the cap, undermining of the attainment demonstration, emissions monitoring and program ev aluations. After reviewing the comments and the State response to the eight issues raised in the proposed rulemaking, EPA has concluded that the Texas MECT program fully satisfies all rele vant guidance and the Clean Air Act.

Approval and Promulgation of Air Quality Implementation Plans; Texas; Low-Emission Diesel Fuel Compliance Date

AGENCY: Environmental Pr otection Agency (EPA). ACTION: Final approval.

------------------------------------ ----------------- ---------- --------

SUMMARY: The EPA is granting final approval to a revision to the Texas Low Emission Diesel (TXLED) fuel program State Implementation Plan (SIP ) that applies in 110 c ounties in the eastern and central parts of Texas. Under sec tion 553(d)(1) of the Administrative Pr ocedure Act, EPA is making this action effective upon publication be cause it relieves a restriction.

DATES: This rule is effective April 6, 2005.

**************************************************** II. What Is the Background for This Action?

We approved the original TXLED rule on No vember 14, 2001, (66 FR 57196) as part of the Texas
SIP and also found that it was re lied upon for demonstrating attain ment in the Houston-Galveston
Attainment Demonstration SIP. On December 15, 2004, the Texas Commi ssion on Environmental Quality (TCEQ) Commissioners proposed to re vise the TXLED rule. Among other revisions, the commission proposed to extend the compliance da te from April 1, 2005 to October 1, 2005. The commission proposed this extension because of c oncern about product availability by the current compliance date. On February 16, 2005 the Executive Director of the TCEQ submitted a letter to EPA requesting parallel processing of the compliance date portion of the SIP revision for TXLED. On February 24, 2005, we proposed approval, through parallel processing, of a revision to the SIP that would change the compliance date for TX LED fuel from April 1, 2005, to October 1, 2005, consistent with a proposed revision to the state ru le that the state had noticed for public hearing.C:\Documents and Settings\bdeese\My Documents\Parallel Proce ssing\EPA Region 6 Parallel Proce ssing Federal Registers published 2001 to 2005.doc Bdeese,x7253 Last printed 7/24/2010 5:04:00 PM Page 14 of 15 Page 1 of 2: Texas; Excess Emissions During Startup, Shutdown, and Ma lfunction Activities,
