### 5

I. What Action is EPA Taking? Today we are approving revisions to the Texas SIP that amend 30 TAC Chapter 114, Control ofAir Pollution from Motor Vehicles. These revisions consist ofthe new Rebate Grant Process and the new Texas Clean School Bus Program, and additional revisions to the TERP and Locally Enforced Motor Vehicle Idling Limitations, as submitted to EPA by the TCEQ on May 15,2006, October 10,2006, January 17,2008, and February 28, 2008. Some ofthe revisions we

are approving in this rulemaking are administrative in nature - they identify an acronym and renumber a sequence ofparagraphs. A majority ofthe revisions, however, are substantive in nature. We are approving these revisions in accordance with section 110 ofthe CAA. The EPA is publishing this rule without prior proposal because we view this as a noncontroversial amendment and anticipate no relevant adverse comments. However, in the proposed rules section ofthis Federal Register publication, we are publishing a separate document that will serve as the proposal to approve the SIP revisions ifrelevant adverse comments are received. This rule will be effective on [FEDERAL REGISTER OFFICE: insert date 60 days from date ofpublication in the Federal Register] without further notice unless we receive relevant adverse comments by [FEDERAL REGISTER OFFICE: insert date 30 days from date ofpublication in the Federal Register]. Ifwe receive relevant adverse comments, we will publish a timely withdrawal in the Federal Register informing the public that the rule will not take effect. We will address all public comments in a subsequent final rule based on the proposed rule. We will not institute a second commentperiod on this action. Any parties interested in commenting must do so now. Please note that ifwe receive adverse comments on an amendment, paragraph, or section ofthis rule and ifthat provision may be

### 6 severed from the remainder ofthe rule, we may adopt as final those provisions ofthe rule that are not the subject ofan adverse comment.



### II. Background Section 110 ofthe CAA requires states to develop air pollutionregulations and control strategies to ensure that air quality meets the National AmbientAir Quality Standards (NAAQS) established by EPA. The NAAQS are established under section 109 ofthe CAA and currently address six criteriapollutants: carbon monoxide, nitrogen dioxide, ozone, lead, particulate matter, and sulfurdioxide. A SIP is a set ofair pollutionregulations, control strategies, other

means or techniques, and technical analyses developed by the state, to ensure that air quality in the state meets the NAAQS. It is required by section 110 and other provisions ofthe CAA. A SIP protects air quality primarily by addressing air pollution at its point oforigin. A SIP can be extensive, containing state regulations or other enforceable documents, and supporting information such as emissions inventories, monitoring networks, and modeling demonstrations. Each state must submit regulations and control strategies to EPA for approval and incorporation into the federally-enforceable SIP. The Texas SIP includes a variety ofcontrol strategies, including the TERP, a program that provides funding for owners and operators to reduce emissions from heavy-duty diesel equipment used in areas that are not meeting the NAAQS for ozone. 1 On October 10, 2006, the TCEQ submitted SIP revisions to EPA to revise the existing TERP program by establishing the Rebate Grant Process and the Texas Clean School Bus Program. The Rebate Grant Process will provide fast and simple access to rebate grants underthe TERP. The Texas Clean School Bus

I Although the TERP has several different components, the part ofthe plan that EPA approved into the Texas SIP is the Diesel Emissions Reduction Incentive Program for On-Road andNon-Road Vehicles. See 70 FR 48647 (August 19,2005).

### 7 Program also revises the TERP to fund efforts by school districts to improve the health of children by reducing emissions ofdiesel exhaust from school buses. On January 17,2008, the State submitted SIP revisions that further amend the TERP. These revisions authorize the TCEQ to allow travel on highways and roadways designated by the TCEQ to count toward the requirement that grant-funded vehicles operate at least 75 percentof the annual miles in the eligible counties; lowerthe cost-effectiveness criteria from $13,000 per ton ofNOx reduced to $15,000 per ton ofNOx reduced; and remove the optionthat vehicles, equipment, and engines replaced underthe program may be removed from the State in lieu of being recycled or scrapped. On May 15,2006, the State submitted SIP revisions addressing Locally Enforced Motor Vehicle Idling Limitations. The EPA first approved revisions to the Texas SIP that incorporated Locally Enforced MotorVehicle Idling Limitations on April 11, 2005 (70 FR 18308), for use as

a control strategy to reduce ground-level ozone. The current motor vehicle idling rules limit the idling time for certain motor vehicles. The SIP revisions submitted on May 15, 2006, prohibit idling ofa vehicle within a school zone or within 1,000 feet ofa public school during operating hours; modify the exemption that applies to motor vehicles with a gross vehicle weight rating of 14,000 pounds or less; clarify the intent ofthe rule; and add exemptions to allow idling the primary propulsion engine ofa vehicle to provide air conditioning while using the vehicle to perform an essential function relatedto roadway construction or maintenance, and when powering an air conditioner in the vehicle's sleeperberth for a government-mandatedrest period. On February 28, 2008, the State submittedrevisions to the SIP that further amend Locally Enforced MotorVehicle Idling Limitations. The February 28, 2008 SIP revisions modify the exemptionthat applies to motor vehicles with a gross vehicle weight rating of 14,000 pounds or8 less; extend the expiration date oftwo subsections to September 1, 2009; prohibit idling within 1,000 feet ofhospitals and residential areas; and restrict idling ofvehicles with sleeper berths when there is a vehicle heating and air conditioning hook-up facility located within two miles. Currently, there are no federal regulations governing idling time for motor vehicles. More detail on each ofthese revisions is included below and in the Technical Support Document (TSD). The TSD is provided in the docket for this rulemaking.' We note one more SIP revision, submitted by the State on October 4,2001, which is not included in the TSD for this rulemaking. The State submitted revisions to the SIP on October 4, 2001, that included the repeal of30 TAC 114.507 (Exemptions). Section 114.507 prohibited a motor vehicle with a gross vehicle weight rating greater than 14,000 pounds from idling more than five consecutive minutes in the Houston-Galveston-Brazoria area, from April 1 through October 31 ofeach calendar year. EPA did not take action on this portion ofthe revision, but on September 6, 2006, EPA approved a revision to the Texas SIP that removed from the SIP "Division 1: Motor Vehicle Idling Limitations," which included section 1)4.507(see 71 FR 52670). Therefore, that portion ofthe State's October 4,2001 submittal that pertains to section 114.507 will not be acted on by EPA because it is superseded by the September 6, 2006 rulemaking.

III. What Did the State Submit? A. The Rebate Grant Process The Rebate Grant Process is new within 30 TAC Chapter 114, Control ofAir Pollution from Motor Vehicles; Subchapter K, Mobile Source Incentive Programs; Division 3, Diesel

2 The docket for this rulemaking, which includes a TSD, is available at www.regulations.gov. The docket number is EPA-R06-0AR-2006-0988.9 Emissions Reduction Incentive Program for On-Road and Non-Road Vehicles. The rule was adopted by the State on September 20, 2006, and submitted to EPA for approval into the SIP on October 10, 2006. The Rebate Grant Process is codified at 30 TAC 114.624 and will provide for fast and simple access to TERP funds, using a streamlinedprocess to award standardized rebates for designated project types. The State may award rebate grants for a specific region or statewide, limit or expandthe project types to further the goals ofthe program, and designate another entity to administer the grants. The EPA is approving this revision to the SIP because it is consistent with section 110(1) ofthe CAA. The EPA notes, however, that in the DFW and Houston SIPs, certain commitments have been approved into the SIP for reducing NOxas necessary for the areas to reach attainment.' Texas must continue to insure that these commitments are met. B. Texas Clean School Bus Program The Texas Clean School Bus Program is a new division in 30 TAC Chapter 114, Control ofAir Pollution from Motor Vehicles; Subchapter K, Mobile Source Incentive Programs; Division4, Texas Clean School Bus Program. The rule was adopted by the State on September 20, 2006, and submittedto EPA for approval into the SIP on October 10, 2006. There are five new sections within Division 4. Section 114.640 (Definitions) identifies and defines the terms used in the Texas Clean School Bus Program: (1). Dieselexhaust, (2). Incremental Cost, (3). Qualifyingfuel, (4). Repower, and (5). Retrofit. Section 114.642 (Applicability) establishes program eligibility for school districts and charter schools statewide; the program is not limited to nonattainment areas. This section also allows regional planning organizations, such as Councils ofGovernment and private non-profit organizations, to apply for

3 For specific commitments that have been established for reducing NOx, as necessary, for DFW and Houston to reach attainment, please see the DFW SIP approved on January 14,2009 (74 FR 01903), and the Houston SIP approved on September 6, 2006 (71 FR 52670).10

and receive grants to improve the program. Section 114.644 (Clean School Bus Program Requirements) establishes the basic program requirements for the Clean School Bus Program, including: the types ofprojects eligible for a Clean School Bus grant; allowance for the TCEQ to limit and/or prioritize funding in a particular funding period to certain areas ofthe State; allowance for the TCEQ to establish other criteria in a particular funding period, including reductions in diesel exhaustemissions to be achieved and additional pollutants to be addressed; the minimum use and useful life ofa projectunder the grantprogram; a requirement that for a proposed project that includes a replacement ofequipment or a repower, the old equipment or engine must be recycled, scrapped, or otherwise permanently removed from the State; strict adherence to the application form; allowance ofthe use ofgrant funds to pay incremental costs associated with the project and prohibition againstusing the grant for administrative expenses; prohibition against use ofgrant funds to meet federal or State legal requirements and for credit under any State or federal emissions reductions credit averaging, banking, or trading program;" and allowance for the TCEQ to require thatthe grantrecipientreturn some or all ofthe grant funds ifthey fail to meet the terms ofa project grant or conditions ofthe Texas Clean School Bus Program. Section 114.646 (Monitoring, Recordkeeping, andReportingRequirements) requires grantrecipients to adhere to the reporting requirements oftheir grant. Reports must

occur at least annually. Section 114.648 (Implementation Schedule) establishes thatthe Texas Clean School Bus Program will expire on August 31,2013. Although the rules found in new Division 4 establish the needed framework for a clean school bus program, the Texas Clean School Bus Program would be funded by TERP only if

4 Except as provided under Texas Health and Safety Code, section 386.056, which states that an owner or operator ofa site located in the Houston-Galveston or Dallas-Fort Worth nonattainment area may, under certain circumstances, use emissions reductions generated by a program established under this chapterto offset the requirements ofcommissionrules relating to control ofair pollution from oxides ofnitrogen.11 TCEQ is given the necessary appropriation authority by the Texas State legislature (Texas Constitution, Article VIII, Section 6) and TERP revenues reach levels required to fund the program (Texas Health and Safety Code, section 

### 386.252). The Texas Clean School Bus Program remained unfunded during the 2006-2007 biennium because an appropriation was not made by the Texas State legislature. However, the program was funded during the 2008-2009 biennium after the Texas State Legislature gave TCEQ the necessary appropriation authority (House BillNo. 1, 8151Legislature, Regular Session, General Appropriations Act). In a letter dated May 16, 2006, EPA provided TCEQ with comments, stating that in order for the Texas Clean School Bus Program to be approvable into the SIP under the Economic Incentive Program (EIP), reductions created by the plan must be surplus, quantifiable, enforceable, and permanent, and should be made consistent with the principles ofequity and environmental benefit. 5 In their submittal, TCEQ confirmed that the Texas Clean School Bus Program meets the requirements ofa financial mechanism EIP under EPA's ImprovingAir Quality with Economic Incentive Programs guidance. Our analysis ofthis revision's consistency with EPA's EIP guidelines can be found in the TSD, which is provided in the docket for this rulemaking. The EPA is approving the above revisions to the SIP, which establishthe needed framework for the Texas Clean School Bus Program, because they are consistent with section 110(1) ofthe CAA and EPA's EIP guidance. However, EPA notes once again that in the DFW and Houston SIPs, certain commitments have been approved into the SIP for reducing NOx as necessary for the areas to reach attainment. Texas must continue to insure that these commitments are met. 

## e. The Texas Emissions Reduction Plan (l'ERP)

5 See EPA's Improving Air Quality with Economic Incentive Programs guidance, chapters 4 and 8 (January 2001).12 The TERP is found in 30 TAC Chapter 114, Control ofAir Pollution from Motor Vehicles; Subchapter K, Mobile Source Incentive Programs; Division 3, Diesel Emissions Reduction Incentive Program for On-Road and Non-Road Vehicles. Revisions to the TERP

were adopted by the State on September 20, 2006 and submitted to EPA for approval into the SIP on October 10, 2006. Subsequentrevisions to the TERP were adopted by the State on December 5, 2007 and submitted to EPA for approval into the SIP on January 17,2008. These

are explained in detail below. The October 10, 2006 submittal provides for clarification ofthe definition of"costeffectiveness," as it applies to the TERP. The amendment to paragraph (1) in section 114.620 (Definitions) modifies the definition of"cost-effectiveness" to clarify how the cost-effectiveness ofTERP grant applications will be determined. Cost-effectiveness is defined as the total dollar amount expended divided by the total number oftons ofNOxemissions reduction attributable to that expenditure. In calculating cost-effectiveness, one time grants ofmoney at the beginning of

a project shall be annualized using a time value ofpublic funds or discount rate determined for each projectby TCEQ, taking into account the interest rate on bonds and interest earned by state funds. In addition, amendments to paragraphs (8) and (10) in section 114.620, replace the acronym "EPA" with "United States Environmental Protection Agency." The EPA is approving these amendments because they will improve TERP program effectiveness by ensuring that the cost-effectiveness ofprojects under the TERP is accurately calculated. The revisions submitted on October 10, 2006 also address section 114.622 (Incentive Program Requirements). Revisions to subsection (d) in section 114.622 establish that the TCEQ may set lower cost-effectiveness limits as needed to ensure the best use ofavailable funds, which will allow spending a larger amount ofmoney per ton ofNOxreduced. In addition to cost-13 effectiveness, the TCEQ may base project selection decisions on other measures when evaluating the effectiveness ofprojects in reducing NOx emissions in relation to the funds to be awarded. While many ofthe most cost-effective projects have already been completed, old, polluting equipment remains in use in nonattainrnent areas and this revision would increase the eligibility ofaportion ofthat equipment for TERP funding. The EPA is approving this amendment because it will allow TERP to fund less cost-effective projects that nevertheless would reduce NOx emissions in nonattainrnent areas. A portion ofthe October 10, 2006 revision to subsection (d) in section 114.622, which specifies that the cost-effectiveness ofa proposed project under the TERP program must not exceed a cost-effectiveness of$13,000 per ton ofNOx emissions reduced, is superseded by a revision in the January 17, 2008 submittal, which further lowers the cost-effectiveness limits for projects to $15,000 per ton ofNOxemissions reduced. In addition, the amendmentto subsection (c) ofsection 114.622, which requires that old equipment or engines that are part ofa proposed project that includes a replacement ofequipment or a repower be recycled, scrapped or otherwise permanently removed from the State, is superseded by the January 17,2008 submittal, which requires grant recipients to recycle or scrap the old equipment or engine, except in specific grants in which the applicant provides sufficient assurances that an old locomotive will not be returned to the State. The EPA is approving these revisions because they will improve TERP program effectiveness by increasing the pool ofeligible applicants for TERP funds and by providing greater certainty that older, higher emitting equipment will be removed from service. The January 17, 2008 submittal also revises subsection (b) ofsection 114.622 (Incentive Program Requirements), which authorizes the TCEQ to allow vehicles replaced or repowered under the TERP to travel on highways and roadways, or portions ofa highway or roadway,14 designated by the TCEQ and located outside a nonattainment area or affected county to count towards the percentage-of-use requirement when determining eligibility for TERP grants. Previously, not less than 75 percent ofthe vehicle miles traveled or hours ofoperation projected for the five years immediately following the award ofa grant were required to be projected to take place in a nonattainment area or affected county in Texas. The requirement that at least 75 percent ofthe vehicle miles traveled or hours ofoperation projected for the five years immediately following the award ofa grant must be projected to take place in a nonattainment

area or affected county ofthe state ofTexas, or on highways and roadways designated by the TCEQ and located outside a nonattainment area or affected county, is only used to determine TERP program eligibility. According to the TERP guidelines, usage outside ofthe nonattainment areas or affected counties will not count towards the emissions reductions used to determine the cost-effectiveness ofthe project. The EPA is approving this revision to the SIP because it will result in more vehicles traveling in and around the nonattainment areas to be eligible for TERP grants. The EPA is approving the above revisions to the TERP program into the SIP because they are consistent with section 11O(1) ofthe CAA, they give the State additional flexibility to allocate TERP funds to achieve the air quality goals ofthe State, and the TERP continues to be consistent with EPA's ErP guidance." EPA notes, however, that in the DFW and Houston SIPs, certain commitments have been approved into the SIP for reducing NOx as necessary for the areas to reach attainment. Texas must continue to insure that these commitments are met. D. LocallyEnforcedMotor Vehicle Idling Limitations

6 For our analysis ofthe consistency ofthe TERP revisions with EPA's ImprovingAir Quality with Economic Incentive Programs guidance (January 200 I), please see the TSD, which is located in the docket for this rulemaking.15 The Locally Enforced Motor Vehicle Idling Limitations are found in 30 TAC Chapter 114, Control ofAir Pollution from Motor Vehicles; SubchapterJ, Operational Controls for Motor Vehicles; Division 2, Locally Enforced Motor Vehicle Idling Limitations. This rule can be implemented within thejurisdiction ofany local government in the State that has signed a Memorandum ofAgreement (MOA) with the TCEQ. The local government that signs the MOA is delegated the authority to enforce the rule within itsjurisdiction. Thus far, numerous cities and counties in the Austin and Dallas-Fort Worth areas have adopted these regulations." Revisions to Division 2 were adopted by the State on April 26, 2006, and submitted to EPA for approval into the SIP on May 15,2006. Subsequent revisions to Division 2 were adopted by the State on January 30, 2008, and submitted to EPA for approval into the SIP on February 28,2008. These are explained in detail below. The May 15, 2006 submittal revises section 114.512 (ControlRequirementsfor Motor Vehicle Idling). The first amendment simply identifies the existing first paragraph as subsection (a). This paragraph states that no person shall cause, suffer, allow, orpermit the primary propulsion engine ofa motor vehicle to idle for more than five consecutive minutes when the motor vehicle is not in motion during the period ofApril 1 through October 31 ofeach calendar year. The EPA is approving this revision because it allows for existing section 114.512 to be organized into subsections. The second revision to Section 114.512 adds new subsection (b), which states that no driver using the vehicle's sleeper berth may idle the vehicle in a school zone or within 1,000 feet ofa public school during its hours ofoperation, an offense ofwhich may be punishable by a fine

7 For a current list ofareas implementing idling restrictions in North Texas, visit http://www.nctcog.org/trans/air/programs/idling/index. asp. For a current list ofareas implementing idling restrictions in the Austin area, visit http://www.tceq.state.tx.us/implementationlairlsip/vehicleidling.html.16 not to exceed $500. A portion ofnew subsection (b) in section 114.512 (submitted May 15, 2006), which establishes that this particular subsection expires on September 1,2007, is superseded by a revision in the February 28, 2008 submittal, which extends the expiration date to September 1, 2009. The February 28, 2008 submittal also revises subsection (b) by adding language to prohibit idling by drivers using the vehicle's sleeperberth in residential areas'' or within 1,000 feet ofa hospital. The EPA is not taking action on the revisions to subsection (b) of section 114.512 that were submitted on May 15,2006 and February 28, 2008, because the expiration date ofSeptember 1, 2009 has already passed, and subsection (b) is therefore no longer in effect. The May 15,2006 submittal also revises section 114.517 (Exemptions). The amendment to paragraph (1) in section 114.517 continues to exempt motor vehicles with a gross vehicle weight rating of 14,000 pounds or less, but ifbefore September 1,2007, only those that do not have a sleeper berth. This is superseded by the January 28, 2008 revision, which provides the following: paragraph (1) specifies that the control requirements for motor vehicle idling do not apply to "a motor vehicle that has a gross vehicle weight rating of 14,000 pounds or less and does not have a sleeperberth." New paragraph (2) indicates that after September 1,2009, all motor vehicles with a gross vehicle weight rating of14,000 pounds or less will be exempt from the provisions ofsection 114.512 (Control Requirements for Motor Vehicle Idling). This revision simply clarifies that control requirements for motor vehicle idling do not apply to any motor vehicle with a gross vehicle weight rating of 14,000 pounds or less. The Locally Enforced Motor Vehicle Idling Limitations approved into the Texas SIP on April 11, 2005 (70 FR 18308) applied only to heavy duty vehicles with a gross vehicle weight rating greater than 14,000

8 As defined byLocal Government Code, Section 244.00 I, which explains what areas are classified as residential areas.17 pounds, and were not intended to apply to any vehicle with a gross vehicle weight rating of 14,000 pounds or less, regardless ofwhether or not it has a sleeper berth. This revision to section 114.517 allows for consistency with the TX SIP revisions approved in 2005. The EPA is approving these revisions submitted on February 28, 2008 because they provide for clarification ofthe exemptions to the motor vehicle idling limits. EPA is not taking action on the May 15, 2006 revision to paragraph (1) in section 114.517, because it is superseded by the revisions submitted on February 28, 2008. The May 15,2006, submittal also revises section 114.517, paragraphs (4) and (7). In paragraph (4), the phrase "not including" is replaced with "otherthan," such that the paragraph reads that one ofthe exemptions to the control requirements for motor vehicle idling is "the primary propulsion engine ofa motor vehicle providing a power source necessary for mechanical operation, otherthan propulsion, and/or passenger compartment heating, or air conditioning." In paragraph (7), the phrase "comfort/safety" is replaced with "comfort and safety" and the word "those," referring to "vehicles," is removed because it is redundant. In addition, the phrase "or public" is added and the phrase "school buses" is removed, to clarify that the primary propulsion engine ofall motor vehicles intended for commercial or public passengertransportation, or passengertransit operations, are allowed to idle up to a maximum of30 minutes when being used to provide air conditioning or heating necessary for passenger comfort and safety. Furthermore, the exemption regarding the propulsion engine ofmotor vehicles used for passenger transit operations is removed from paragraph (8) and inserted into paragraph (7). Revised paragraph (7) now reads that the provisions ofsection 114.512 do not apply to "the primary propulsion engine ofa motor vehicle that is being used to supply heat or air conditioning necessary for passenger comfort and safety in vehicles intended for commercial or public18

passenger transportation, or passenger transit operations, in which case idling up to a maximum of30 minutes is allowed." Language is added to paragraph (8), exempting the primary propulsion engine ofa motor vehicle being used to provide air conditioning orheating necessary for employee health or safety while the employee is using the vehicle to perform an essentialjob function related to roadway construction or maintenance, from the control requirements for motor vehicle idling. The new exemption found in paragraph (8) ensures that the control requirements for motor vehicle idling do not conflict with the Texas Department of Transportation guidelines for vehicle idling by employees. The revision to paragraph (8) will assist localjurisdictions in determining enforcementresponsibilities. Text is edited in paragraphs (9) and (10) for clarification: the word "or" is removed from the end ofparagraph (9) to indicate that it is no longer the next to last paragraph; in paragraph (10), the word "who" is replaced with "that" and a period is replaced with a semi-colon and the word "or" is added to the end ofparagraph (10), to indicate that it is no longer the final paragraph in section 114.517. The EPA is approving these revisions because they help to clarify procedures regarding idling restrictions. The May 15,2006 submittal also adds new paragraph (11), which exempts from the control requirements for motor vehicle idling, a motor vehicle when idling is necessary to power

a heater or air conditioner while a driver is using the vehicle's sleeperberth for a governmentmandated rest period. The February 28, 2008 submittal revises paragraph (11) by adding language that prohibits idling to power a heater or air conditioner while a driver is using the vehicle's sleeperberth ifthe vehicle is within two miles ofa facility offering external heating and air conditioning connections at a time when those connections are available. It should be noted that in a letter dated January 17, 2006, EPA provided TCEQ with comments, stating that19 the addition ofexemption (11) would weaken the SIP rules approved by EPA in 2005. We added that we would not be able to approve this revision into the SIP unless TCEQ would provide substitute reductions or modeling to show that attainment can be met without the credits affected by these changes. TCEQ did not revise the rule or provide new substitute reductions or modeling in response to our comments. However, the February 28, 2008 submittal extends the expiration date ofparagraph (11) to September 1,2009, and it should be noted that the expiration date has passed and the exemption is no longer in effect. Therefore, the EPA is not taking action on the revisions to paragraph (11) that were submitted on May 15, 2006 and February 28, 2008. The February 28, 2008 submittal also revises section 114.517 (Exemptions), by renumbering the paragraphs to account for new paragraph (2). The EPA is approving this revision to the SIP because it allows for clarity and consistency in the numbering ofthe paragraphs in section 114.517. The EPA is approving the above revisions to the Locally Enforced Motor Vehicle Idling Limitations into the SIP because they are consistent with section 110(1) ofthe CAA, and because they allow for clarity and consistency ofthe exemptions and control requirements for motor vehicle idling.



### IV. Final Action The EPA is approving revisions to the Texas SIP submitted to EPA on May 15, 2006, October 10,2006, January 17,2008, and February 28, 2008, which apply to 30 TAC Chapter 114, Control ofAir Pollution from Motor Vehicles. These revisions establish the Rebate Grant Process and Texas Clean School Bus Program, and amend the TERP and Locally Enforced Motor Vehicle Idling Limitations. The revisions are consistent with section 110(1) of the Act.20



### V. Statutory and Executive OrderReviews Underthe Clean Air Act, the Administrator is required to approve a SIP submission that complies with the provisions ofthe Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria ofthe Clean Air Act. Accordingly, this action merely approves state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this action: • Is not a "significant regulatory action" subject to review by the Office ofManagement and Budget under Executive Order 12866 (58 FR 51735, October4, 1993); • Does not impose an information collection burden under the provisions ofthe Paperwork Reduction Act (44 U.S.C. 3501 

### et seq.); • Is certified as not having a significant economic impact on a substantial number ofsmall entities under the Regulatory Flexibility Act (5 U.S.C. 601 

### etseq.); • Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Public Law 104-4); • Does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999); • Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997); • Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22,2001);21

• Is not subject to requirements ofSection 12(d) ofthe National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application ofthose requirements would be inconsistent with the Clean Air Act; and • Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994). In addition, this rule does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9,2000), because the SIP is not approved to apply in Indian country located in the state, and EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law. The Congressional Review Act, 5 U.S.c. 801 

### et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy ofthe rule, to each House ofthe Congress and to the Comptroller General ofthe United States. EPA will submit a report containing this action and otherrequired information to the U.S. Senate, the U.S. House ofRepresentatives, and the Comptroller General ofthe United States prior to publication ofthe rule in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register. This action is not a "majorrule" as defined by 5 U.S.C. 804(2). Under section 307(b)(l) ofthe Clean Air Act, petitions forjudicial review ofthis action must be filed in the United States Court ofAppeals for the appropriate circuitby [FEDERAL REGISTER OFFICE: insert date 60 days from date ofpublication of this document in the Federal Register]. Filing a petition for reconsideration by the Administrator ofthis final rule

### 22

does not affect the finality ofthis action for the purposes of judicial review nor does it extend the time within which a petition forjudicial review may be filed, and shall not postpone the effectiveness ofsuch rule or action. This action may not be challenged later inproceedings to enforce its requirements. (See Section 307(b)(2).)
