Approval and Promulgation of Air Quality Implementation Plans; 
Texas; Revision to the State Implementation Plan (SIP) Addressing 
Carbon Monoxide (CO) for El Paso

AGENCY: U.S. Environmental Protection Agency (EPA).

ACTION: Notice of proposed rulemaking.

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

SUMMARY: This action proposes to approve a revision to the Texas SIP 
addressing CO for El Paso. Certain elements of the complete El Paso CO 
SIP were submitted by the Governor of Texas to the EPA in order to meet 
the November 15, 1992, deadline for the purpose of bringing about the 
attainment of the National Ambient Air Quality Standards (NAAQS) for 
CO. These elements satisfy certain Federal requirements for an 
approvable nonattainment area CO SIP for El Paso. Therefore, this 
Federal Register (FR) action only proposes approval of some of the 
elements of the complete El Paso CO SIP, specifically the 1990 base 
year CO emissions inventory and the oxygenated fuels program.
    The remaining elements of the complete El Paso CO SIP, to be 
submitted to the EPA by November 15, 1993, have been or will be acted 
upon in separate FR actions.

dates: Comments on this proposed action must be received in writing by 
May 4, 1994.

SUPPLEMENTARY INFORMATION: A segment of El Paso, Texas, was designated 
nonattainment for CO and classified as moderate with a design value 
below 12.7 parts per million (ppm.) (specifically 12.6), under sections 
107(d)(4)(A) and 186(a) of the Clean Air Act (CAA), upon enactment of 
the Clean Air Act Amendments (CAAA) of 1990.1 Please reference 56 
FR 56694 (November 6, 1991) and 57 FR 13498 and 13529 (April 16, 1992).
---------------------------------------------------------------------------

    \1\The 1990 Amendments to the CAA made significant changes to 
the air quality planning requirements for areas that do not meet (or 
that significantly contribute to ambient air quality in a nearby 
area that does not meet) the CO NAAQS (see Pub. L. Number 101-549, 
104 Stat. 2399). References herein are to the CAA, as amended, 42 
U.S.C. sections 7401 et seq.
---------------------------------------------------------------------------

    The air quality planning requirements for moderate CO nonattainment 
areas with a design value less than or equal to 12.7 ppm. are set out 
in subparts one and three of part D, Title I of the CAA. Subpart one 
contains provisions generally applicable to CO nonattainment areas, and 
subpart three contains provisions specifically applicable to CO 
nonattainment areas. Section 104 of the CAAA of 1990 amended part D of 
Title I of the CAA by adding two additional sections to subpart three 
(sections 186 and 187), which pertain to the classification of CO 
nonattainment areas and to the submission requirements of the SIPs for 
these areas, respectively. At times, subparts one and three overlap or 
conflict. The EPA has attempted to clarify the relationship among these 
various provisions in the General Preamble and, as appropriate, in this 
FR action.
    The EPA has issued a ``General Preamble'' describing the EPA's 
preliminary views on how the EPA intends to review SIPs and SIP 
revisions submitted under Title I of the CAA, including those State 
submittals containing moderate CO nonattainment area SIP requirements. 
See generally 57 FR 13498 (April 16, 1992) and 57 FR 18070 (April 28, 
1992). Because the EPA is describing its interpretations here only in 
broad terms, the reader should refer to the General Preamble for a more 
detailed discussion of the interpretations of Title I advanced in this 
action and the supporting rationale. In this proposed rulemaking action 
on certain elements of the El Paso, Texas, complete moderate CO SIP, 
the EPA is applying its interpretations, taking into consideration the 
specific factual issues presented.
    On October 23, 1992, the Governor of Texas submitted to the EPA a 
SIP revision for CO concerning El Paso, which included the general SIP 
revision and the oxygenated fuels regulations. The State also submitted 
to the EPA a completed emissions inventory on November 17, 1992, and a 
commitment to upgrade the existing I/M Program on November 15, 1992. 
These elements were intended to satisfy the CAA CO SIP requirements due 
on November 15, 1992. The required items for the El Paso CO SIP, due 
November 15, 1992, unless otherwise noted, specifically include: (1) A 
comprehensive, accurate, and current inventory of actual emissions from 
all sources of CO in the nonattainment area (sections 172(c)(3) and 
187(a)(1) of the CAA); (2) no later than September 30, 1995, and no 
later than the end of each three year period thereafter, until the area 
is redesignated to attainment, a revised inventory meeting the 
requirements of sections 187(a)(1) and 187(a)(5) of the CAA; (3) a 
permit program to be submitted by November 15, 1993, which meets the 
requirements of section 173 for the construction and operation of new 
and modified major stationary sources of CO (section 172(c)(5)); (4) 
contingency measures due November 15, 1993, that are to be implemented 
if the EPA determines that the area has failed to attain the primary 
standards by the applicable date (section 172(c)(9)); (5) a commitment 
to upgrade the current I/M program and submit a SIP revision for the I/
M program by November 15, 1993, (section 187(a)(4)); and (6) an 
oxygenated fuels program (section 211(m)). As outlined below, the State 
of Texas' CO SIP revision concerning El Paso, a moderate CO 
nonattainment area, was reviewed against the applicable requirements. 
The reader is referred to the El Paso CO SIP submittal and the EPA's 
supporting technical information, Technical Support Document (TSD), for 
pertinent details regarding each requirement. The TSD is available for 
public review at the addresses indicated above for the EPA Regional 
Office in Dallas, the EPA Washington, D.C. office, and the TNRCC Austin 
office.
    Section 110(k) of the CAA sets out provisions governing the EPA's 
review of SIP submittals (see 57 FR 13565-66). In this FR action, the 
EPA is approving only some of the elements of the complete El Paso CO 
SIP, specifically the 1990 base year CO emissions inventory, and the 
oxygenated fuels program. The inspection and maintenance (I/M) 
committal was addressed by the EPA in an FR notice published on 
September 27, 1993. The remaining elements of the complete El Paso CO 
SIP, to be submitted to the EPA by November 15, 1993, will be acted 
upon in separate FR actions.
    This proposed approval action does not include any approval for the 
El Paso Post-1982 SIP submittal. That SIP proposal was the result of a 
SIP call on February 24, 1984, and one to which the Texas Air Control 
Board (TACB) responded. However, the EPA did not take action regarding 
the SIP submittal, and the CAAA of 1990 have negated the need for the 
EPA to take further action on that SIP action revision submittal.

Analysis of State Submission

1. Procedural Background

    The CAA requires States to observe certain procedural requirements 
in developing implementation plans and plan revisions for submission to 
the EPA. Section 110(a)(2) of the CAA provides that each implementation 
plan submitted by a State must be adopted after reasonable notice and 
public hearing.2 See also section 110(l) of the CAA. Also, the EPA 
must determine whether a submittal is complete and, therefore, warrants 
further EPA review and action. See section 110(k)(1) and 57 FR 13565. 
The EPA's completeness criteria for SIP submittals are set out at 40 
Code of Federal Regulations part 51, appendix V (1993), as amended by 
56 FR 42216 (August 26, 1991). The EPA attempts to make completeness 
determinations within 60 days of receiving a submission. However, a 
submittal is deemed complete by operation of law if a completeness 
determination is not made by the EPA six months after receipt of the 
submission.
---------------------------------------------------------------------------

    \2\Section 172(c)(7) of the Act requires that plan provisions 
for nonattainment areas meet the applicable provisions of section 
110(a)(2).
---------------------------------------------------------------------------

    After providing adequate notice, the TACB public hearings were held 
on July 2, 1992, and September 9, 1992, to entertain public comment on 
certain elements of the complete CO implementation plan. Following the 
public hearing, these elements were adopted by the State on September 
18, 1992, and submitted to the EPA as a proposed revision to the SIP.
    The SIP revision was reviewed by the EPA to determine completeness 
shortly after its submittal, in accordance with the completeness 
criteria referenced above. A letter dated January 15, 1993, was 
forwarded to the Governor indicating the completeness of the submittal 
and the next steps to be taken in the review process.

2. CO Emission Inventory

    Section 172(c)(3) of the CAA requires that nonattainment plan 
provisions include a comprehensive, accurate, and current inventory of 
actual emissions from all sources of relevant pollutants in the 
nonattainment area. The TACB, the TNRCC effective September 1, 1993, 
included the requisite El Paso inventory in the CO SIP. The base year 
for the inventory was 1990, using a three month CO season of November 
1990 through January 1991. Stationary point sources, stationary area 
sources, on-road mobile sources, and nonroad mobile sources of CO were 
included in the inventory. Stationary sources with emissions greater 
than 100 tons per year within a 25-mile buffer of the nonattainment 
area were also included in the inventory. The following list presents a 
summary of the CO peak season daily emissions estimates in tons per day 
(t/d) by source category: Point Sources, nine t/d; Area Sources, three 
t/d; Mobile On-Road Sources, 291 t/d; Mobile Nonroad Sources, 67 t/d; 
Total Sources, 370 t/d. Available guidance for preparing emission 
inventories is provided in the General Preamble (57 FR 13498, April 16, 
1992). Section 110(k) of the CAA sets out provisions governing the 
EPA's review of base year emission inventory submittals in order to 
determine approval or disapproval under section 182(a)(1). See 57 FR 
13565-66, April 16, 1992. The EPA is proposing to grant approval of the 
El Paso CO base year emission inventory submitted to the EPA based on 
Level I, II, and III review findings. The following paragraphs outline 
the review procedures performed on the inventory.
    The Level I and II review process is used to determine that all 
components of the base year inventory are present. The review also 
evaluates the level of supporting documentation provided by the State, 
and assesses whether the emissions were developed according to current 
EPA guidance.
    The Level III review process is outlined here and consists of nine 
points that the inventory must include. For a base year emission 
inventory to be acceptable, it must pass all of the following criteria: 
(1) An approved Inventory Preparation Plan (IPP) must be provided and 
the Quality Assurance contained in the IPP must be performed and its 
implementation documented; (2) Adequate documentation must be provided 
that enables the reviewer to determine the emission estimation 
procedures and the data sources used to develop the inventory. Summary 
emissions by categories of source type must be provided; (3) The point 
source inventory must be complete; (4) Point source emissions must have 
been prepared or calculated according to the current EPA guidance; (5) 
The area source inventory must be complete; (6) The area source 
emissions must have been prepared or calculated according to the 
current EPA guidance; (7) The methods used to develop vehicle miles 
traveled (VMT) estimates (e.g., a network transportation planning 
model) must follow EPA guidance. The VMT methods must be adequately 
described and documented in the inventory report; (8) The MOBILE model 
must be correctly used to produce emission factors for each of the 
vehicle classes; and (9) Nonroad mobile emissions must be prepared 
according to current EPA guidance for all of the source categories.
    The base year emission inventory will be approved if it passes 
Levels I, II, and III of the review process. Detailed Level I and II 
review procedures can be found in the following document--``Quality 
Review Guidelines for 1990 Base Year Emission Inventories,'' U.S. 
Environmental Protection Agency, Office of Air Quality Planning and 
Standards (OAQPS), Research Triangle Park, North Carolina, July 27, 
1992. Level III review procedures are specified in a memorandum from 
John S. Seitz to the Regional Air Division Directors, entitled 
``Emission Inventory Issues,'' June 24, 1993.3

    \3\Memorandum from John S. Seitz, Director, Office of Air 
Quality Planning and Standards, to the Regional Air Division 
Directors, entitled ``Emission Inventory Issues,'' U.S. EPA, Office 
of Air Quality Planning and Standards, Research Triangle Park, North 
Carolina, June 24, 1993.
---------------------------------------------------------------------------

    The TACB submitted the El Paso CO inventory on November 17, 1992. 
EPA Region 6, EPA's OAQPS Emissions Inventory Branch, and contractor's 
reviewed the inventory. Comments were sent to the TACB, and the TACB 
responded with a resubmittal. The resubmittal underwent a second 
review. The review directive comments were given to Texas and discussed 
during an on-site visit to Austin, Texas, on September 2, 1993. The EPA 
Office of Mobile Sources (OMS) comments on El Paso ozone were also 
considered, where applicable.
    Texas addressed the final directive comments and the OMS comments 
and submitted revised submittal documentation to Region 6 on October 4, 
1993, along with documents responding to the directive comments and the 
OMS comments. Region 6 compared the Texas responses with the 
deficiencies noted in the final directive review and OMS comments and 
concluded that Texas had adequately addressed the remaining 
deficiencies so that Region 6 could verify that Texas had satisfied the 
Level III criteria for El Paso CO.
    Documentation of the Region 6 evaluation, including details of the 
review procedure, is contained in a memorandum (Attachment A) in the 
TSD.
    Also, please reference Appendix AK of the El Paso CO SIP for 
specific details on the State inventory. Finally, it should be noted 
that no later than September 30, 1995, and no later than the end of 
each three year period thereafter (until the area is redesignated to 
attainment), the TACB (now TNRCC) will be required to submit to the EPA 
a revised inventory meeting the requirements of sections 187(a)(1) and 
187(a)(5) of the CAA.

3. Nonattainment New Source Review (NSR) Permit Program

    The State of Texas submitted NSR regulatory revisions to the EPA on 
May 13, 1992, and November 3, 1992, respectively. NSR regulatory 
revisions were also included in a submittal by the State on August 31, 
1993. The revisions were due independently of the November 15, 1992, 
moderate CO nonattainment area SIP requirements addressed in this FR 
action. The EPA action on the El Paso CO nonattainment NSR permit 
program will be addressed in detail in future separate FR notices.

4. Contingency Measures

    As per section 172(c)(9) of the CAA, all nonattainment SIPs must 
contain contingency measures (due November 15, 1993) that are to be 
implemented if the area fails to make reasonable further progress (RFP) 
or to attain the NAAQS by the applicable date. These contingency 
measures are to be implemented immediately after the EPA determines 
failure of RFP or attainment of standards. The contingency measures for 
the El Paso SIP, due independently of the November 15, 1992, moderate 
CO nonattainment area SIP requirements addressed in this FR action, 
were received by the EPA Region 6 on November 15, 1993, and will be 
addressed in a separate FR action.

5. I/M SIP Revision

    Section 187(a)(4) of the CAA provides a savings clause for vehicle 
I/M programs. All moderate CO nonattainment SIPs must include a vehicle 
I/M program as described in section 182(a)(2)(B). The State of Texas 
adopted State rules and currently is operating a State I/M program in 
El Paso, Texas. The State of Texas has also submitted a committal SIP 
for the El Paso CO nonattainment area to the EPA, in accordance with 
provisions of the General Preamble (57 FR 13530), stating that a 
comprehensive SIP revision will be submitted to the EPA by November 15, 
1993, which will upgrade the existing El Paso, Texas, I/M program to 
meet the new requirements mandated by the CAAA of 1990. The EPA 
proposed approval of the committal SIP in a separate FR action 
published on September 27, 1993.

6. Oxygenated Fuels Program

    Motor vehicles are significant contributors of CO emissions. An 
important measure toward reducing these emissions is the use of 
cleaner-burning oxygenated gasoline. Extra oxygen, contained within the 
oxygenate in the fuel, enhances fuel combustion and helps to offset 
fuel-rich operating conditions, particularly during vehicle starting, 
which are more prevalent in the winter.
    Section 211(m) of the CAAA requires that various States submit 
revisions to their SIPs, and implement oxygenated gasoline programs by 
no later than November 1, 1992. This requirement applies to all States 
with CO nonattainment areas with design values of 9.5 ppm. or more, 
which is based generally on 1988 and 1989 data. Each State's oxygenated 
gasoline program must require gasoline sold or dispensed in the 
specified control area to contain not less than 2.7 percent oxygen by 
weight during that portion of the year in which the area is prone to 
high ambient concentrations of CO (the control period).
    The EPA announced guidance on the establishment of control periods, 
by area, in the FR on October 20, 1992.4 The EPA also announced 
the availability of oxygenated gasoline credit program guidelines in 
the October 20, 1992, FR.5 Under a credit program, marketable 
oxygen credits may be generated from the sale of gasoline with a higher 
oxygen content than is required (i.e., an oxygen content greater than 
2.7 percent by weight). These oxygen credits may be used to offset the 
sale of gasoline with a lower oxygen content than is required. As an 
alternate to the credit program, the State may elect a program in which 
a minimum of 2.7 percent by weight oxygen must be present in every 
gallon of gasoline sold.
---------------------------------------------------------------------------

    \4\ See ``Guidelines for Oxygenated Gasoline Credit Programs and 
Guidelines on Establishment of Control Periods under section 211(m) 
of the CAA as Amended--Notice of Availability,'' 57 FR 47849 
(October 20, 1992).
    \5\ See note 4, above. The EPA issued guidelines for credit 
programs under section 211(m)(5) of the CAA.
---------------------------------------------------------------------------

    The EPA also issued labeling regulations under section 211(m)(4) of 
the CAA. These labeling regulations were published in the FR on October 
20, 1992.6
---------------------------------------------------------------------------

    \6\ See ``Notice of Final Oxygenated Fuels Labeling Regulations 
under section 211(m) of the Clean Air Act as Amended--Notice of 
Final Rulemaking,'' 57 FR 47769. The labeling regulations may be 
found at 40 CFR part 80, section 80.35.
---------------------------------------------------------------------------

    The State of Texas adopted amendments to its TACB Regulation IV, 
Control of Air Pollution from Motor Vehicles, Chapter 114, to add a 
Section 114.13, which establishes an Oxygenated Fuel Program for El 
Paso. The TACB (now TNRCC) Board approved the Regulation IV revisions 
on September 18, 1992. The program covers the County of El Paso, Texas 
(the control area), which is also the El Paso Metropolitan Statistical 
Area. In this action, the EPA is proposing approval of the El Paso 
oxygenated fuel program, based on the TACB's revised Chapter 114, 
Control of Air Pollution from Vehicles, section 114.13, Oxygenated 
Fuels. The State has entered into an agreement with the El Paso City/
County Health Department (known as the El Paso Local Air Pollution 
Control Program) for that agency to assist the State with the 
administration of the oxygenated fuels program. The agreement, in the 
form of grant objectives, details the activities that El Paso will 
undertake for the State in the administration of the oxygenated fuels 
program. Examples of the activities the El Paso City/County Health 
Department performs for the State in the oversight of the oxygenated 
fuels program include sampling 20 percent of the affected facilities 
and reporting on the number of violations during the control period. 
The TNRCC is, however, ultimately responsible for the administration, 
oversight, and enforcement of the El Paso oxygenated fuels program.
    The control period for the program is from October 1 of one year to 
March 31 of the following year, and the program is one in which all 
oxygenated gasoline must contain a minimum oxygen content of 2.7 
percent by weight of oxygen. The State has adopted labeling 
regulations, enforcement procedures, and oxygenate test methods in 
conformity with Federal regulations. For further details of the 
oxygenated fuels program, the reader is referred to the TSD.

7. Enforceability Issues

    All measures and other elements in the SIP must be enforceable by 
the State and the EPA. See sections 172(c)(6), 110(a)(2)(A) and 57 FR 
13556. The EPA criteria addressing the enforceability of SIPs and SIP 
revisions were stated in a September 23, 1987, memorandum (with 
attachments) from J. Craig Potter, Assistant Administrator for Air and 
Radiation, et al. See 57 FR 13541. The criteria include, for example: 
ensuring that the rules contained in the SIP are explicit in their 
applicability to the regulated sources; ensuring that compliance dates 
are clearly specified; ensuring that compliance periods and test 
methods are clearly noted; ensuring that adequate recordkeeping is 
required; and ensuring that any exemptions or variances are clear in 
their applicability and in how they are triggered. In addition to 
enforceable requirements, nonattainment area plan provisions must 
contain a program that provides for enforcement of the control measures 
and other elements in the SIP. See section 110(a)(2)(C).
    The State of Texas has an enforcement program that will ensure that 
certain control measures contained in the El Paso CO SIP (i.e., the 
oxygenated fuels) are adequately enforced. As stated in the oxygenated 
fuels section of this FR notice, the State has an agreement with the El 
Paso City/County Health Department for that agency to assist the TACB 
(now TNRCC) in its oversight activities regarding the oxygenated fuels 
program. The State, however, is responsible for the administration, 
oversight, and enforcement of the El Paso oxygenated fuels program.

8. Attainment Demonstration

    There is no attainment demonstration required for CO nonattainment 
areas with design values equal to or below 12.7 ppm. and El Paso's 
design values are less than 12.7 ppm.
    However, the International Border provision (section 179B of the 
CAA commonly referred to as section 818 of the CAAA), provides a State 
on an international border, such as Texas, an option to satisfy the EPA 
Administrator regarding attainment of the NAAQS by the statutory 
deadline. Specifically, section 179B provides that a nonattainment area 
on an international border that fails to meet NAAQS will not be 
reclassified if it can demonstrate attainment ``but for emissions 
emanating from outside the United States.'' Criteria for a section 818 
demonstration are further discussed in the TSD. The TACB (now TNRCC) 
included in this SIP revision its intention to perform a section 818 CO 
technical analysis for El Paso. The EPA will take action on a section 
818 El Paso CO demonstration, if one is submitted, in a future FR 
notice.

Proposed Action

    The EPA in this action is proposing to approve the following 
elements of the complete El Paso CO SIP: The 1990 base year CO 
emissions inventory and the oxygenated fuels program. The remaining 
elements of the complete El Paso CO SIP to be submitted to the EPA by 
November 15, 1993, will be acted upon in separate FR actions.
    The EPA has reviewed these revisions to the El Paso CO SIP and is 
proposing to approve them as submitted.

Request for Public Comments

    The EPA is requesting comments on all aspects of today's proposal. 
As indicated at the outset of this notice, the EPA will consider any 
comments received by May 4, 1994.

Miscellaneous

    Under the Regulatory Flexibility Act, 5 U.S.C. 600 et seq., the EPA 
must prepare a regulatory flexibility analysis assessing the impact of 
any proposed or final rule on small entities (5 U.S.C. 603 and 604). 
Alternatively, the EPA may certify that the rule will not have a 
significant impact on a substantial number of small entities. Small 
entities include small businesses, small not-for-profit enterprises, 
and government entities with jurisdiction over populations of less than 
50,000.
    SIP approvals under section 110 and Subchapter I, part D, of the 
CAA do not create any new requirements, but simply approve requirements 
that the State is already imposing. Therefore, because the Federal SIP-
approval does not impose any new requirements, I certify that it does 
not have a significant impact on any small entities affected. Moreover, 
due to the nature of the Federal-State relationship under the CAA, 
preparation of a regulatory flexibility analysis would constitute 
Federal inquiry into the economic reasonableness of State action. The 
CAA forbids the EPA to base its actions concerning SIPs on such grounds 
(Union Electric Co. v. U.S. E.P.A., 427 U.S. 246, 256-66 (S. Ct. 1976); 
42 U.S.C. section 7410(a)(2).

Executive Order 12866

    This action has been classified as a table 2 action by the Regional 
Administrator under the procedures published in the Federal Register on 
January 19, 1989 (54 FR 2214-2225), as revised by an October 4, 1993, 
memorandum from Michael H. Shapiro, Acting Assistant Administrator for 
Air and Radiation. A future notice will inform the general public of 
these tables. On January 6, 1989, the Office of Management and Budget 
(OMB) waived table 2 and table 3 SIP revisions (54 FR 2221) from the 
requirements of Section 3 of Executive Order 12291 for 2 years. The EPA 
has submitted a request for a permanent waver for table 2 and table 3 
SIP revisions. The OMB has agreed to continue the temporary waiver 
until such time as it rules on EPA's request. This request continues in 
effect under Executive Order 12866 which superseded Executive Order 
12291 on September 30, 1993.
