SUPPLEMENTARY INFORMATION

I. Background.

A. Summary

    EPA is finalizing approval of the emissions inventory, control 
measures, and 15% rate-of-progress (ROP) plan for the Santa Barbara 
County ozone nonattainment area, as included in the 1994 California 
Ozone SIP.1 This action was proposed on March 18, 1996, as part of 
action on the 1994 California Ozone SIP (61 FR 10920-10962). EPA has 
separately finalized approval of all elements proposed for approval in 
that document, with the exception of Santa Barbara plan elements. The 
reader is referred to the notice of proposed rulemaking for additional 
detail on the SIP submittal (including State measures and analyses), as 
well as a summary of relevant Clean Air Act requirements and EPA 
interpretations of those requirements.
---------------------------------------------------------------------------

    \1\ The Federal ozone nonattainment area is the ``Santa Barbara-
Santa Maria-Lompoc Area,'' which comprises the entire County of 
Santa Barbara (see 40 CFR 81.305).
---------------------------------------------------------------------------

    Santa Barbara is currently classified as a moderate nonattainment 
area for ozone (40 CFR 81.305). As a result, the SIP must contain 
adequate control measures and commitments to demonstrate attainment of 
the ozone national ambient air quality standards (NAAQS) by 1996, in 
accordance with sections 181(a)(1) and 172(c)(6) of the CAA.
    The 1994 SIP employed an urban airshed modeling analysis to 
demonstrate that the control strategy will result in NAAQS attainment 
by the deadline. After the 1994 SIP had been prepared, exceedances of 
the ozone NAAQS were recorded during both 1994 and 1995. This precluded 
Santa Barbara from achieving the ozone standard by 1996.2
---------------------------------------------------------------------------

    \2\ Attainment of the ozone NAAQS is achieved when the number of 
exceedances at each monitoring site within the area, averaged over 
the past 3 calendar years, is less than or equal to 1. An exceedance 
is a daily maximum hourly average ozone concentration that is 
greater than the 0.12 ppm standard. (40 CFR 50, App. H)
---------------------------------------------------------------------------

    Section 181(a)(5) of the Act, however, authorizes EPA to grant a 
one-year extension of the attainment date upon request by the State, if 
an area has complied with all requirements in the SIP and records no 
more than one exceedance during the attainment year. Based on this 
provision, EPA proposed to approve Santa Barbara's plan as meeting the 
attainment demonstration requirements of section 182(b)(1)(A) of the 
Act, assuming that the area experienced no more than one exceedance 
during the 1996 ozone season.
    After the proposed approval of the Santa Barbara plan was issued in 
March 1996, several locations in Santa Barbara recorded exceedances of 
the ozone standard. These exceedances now disqualify the area from 
receiving a one-year attainment deadline extension. Therefore, there is 
no longer a basis for EPA's proposed approval of the attainment 
demonstration and the supporting modeling analysis. For this reason, 
CARB has withdrawn the attainment demonstration portion of the 
SIP.3
---------------------------------------------------------------------------

    \3\ November 6, 1996 letter from Michael P. Kenny, Executive 
Officer, CARB, to Felicia Marcus, Regional Administrator, EPA, 
withdrawing the Santa Barbara ozone attainment demonstration. The 
letter also encloses an October 18, 1996 letter from Douglas W. 
Allard (SBCAPCD) to Michael P. Kenny, requesting withdrawal of the 
attainment demonstration. Allard's letter notes that, on October 17, 
1996, ``the Air Pollution Control Board directed me to request that 
the Air Resources Board withdraw the attainment demonstration 
element from the 1994 Clean Air Plan (CAP), a component of the State 
Implementation Plan.''
---------------------------------------------------------------------------

    Because the State has withdrawn this SIP element, EPA is not 
responding in this document to extensive Environmental Defense Center 
comments on EPA's proposed approval of Santa Barbara's modeling and 
attainment demonstration. EPA encourages the State and local agencies 
to address those comments, to the extent that they remain relevant, in 
the preparation of attainment demonstrations in the future.

B. SIP Submittals

    On November 15, 1994, CARB adopted and submitted a revision to the 
``State of California Implementation Plan for Achieving and Maintaining 
the National Ambient Air Quality Standards'' (ozone SIP). The revision 
consists of: (a) The State's comprehensive ozone plan, including the 
State's own measures and the State's summaries of, and revisions to, 
the local plans; (b) the State's previously adopted regulations for 
consumer products and reformulated gasoline and diesel fuels; and (c) 
local plans addressing the ozone attainment demonstration and ROP 
requirements. EPA has previously finalized approval of all of the 
State's measures and most of the elements of the local plans, with the 
exception of the plan for Santa Barbara.
    EPA is today approving elements from the following ozone SIP 
submittals:
    1. ``1994 Clean Air Plan for Santa Barbara County,'' adopted by the 
Board of the Santa Barbara County Air Pollution Control District on 
November 2, 1994. The November 14, 1994, submittal letter for this plan 
is from James Boyd, Executive Officer of CARB, to EPA Regional 
Administrator Felicia Marcus.
    2. On March 30, 1995, CARB submitted revised 1990 base year 
emission inventories for each of the California ozone nonattainment 
areas. EPA is approving in this document the Santa Barbara portion of 
the State's submittal.

C. EPA Completeness Findings

    On April 18, 1995 the EPA issued a finding of completeness, 
pursuant to 40 CFR Part 51, Appendix V, for the Santa Barbara plan 
portion of the November 1994 and March 1995 submittals with regard to: 
(1) 15% ROP requirement of section 182(b)(1)(A); and (2) 1990 base year 
inventory requirements of section 182(a)(1).4
---------------------------------------------------------------------------

    \4\ EPA adopted the completeness criteria on February 16, 1990 
(55 FR 5830) and, pursuant to section 110(k)(1)(A) of the CAA, 
revised the criteria on August 26, 1991 (56 FR 42216).

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

II. Review of the SIP Submittal, Response to Comments on Specific SIP 
Issues, and EPA Final Action

A. Emissions Inventory

    The Environmental Defense Center (EDC) provided two comments on the 
emissions inventory. First, EDC stated that significant amounts of 
emissions from variances and violations, construction activities, and 
small source exemptions are excluded from the inventory. Second, EDC 
stated that the 1996 inventory misstates emissions by not removing from 
the inventory those emissions associated with the shutdown of the 
Battles Gas plant in July 1995, thus allowing banking of these 
emissions.
    The emission inventories for Santa Barbara were developed in 
accordance with EPA guidance, using the most accurate data 
available.5 The SIP's base year and projected inventories include 
the District's best estimations of emissions from construction 
activities and, to the extent data are available, emissions from 
unpermitted sources. The 1990 baseline inventories and the projected 
inventories also address variances and violations through use of 
control factors that reflect general estimations of rule effectiveness.
---------------------------------------------------------------------------

    \5\ See the list of SIP inventory guidance documents in the 
supplement to EPA's General Preamble for the Implementation of Title 
I of the Clean Air Act Amendments of 1990, issued on April 28, 1992 
(57 FR 18070-18071).
---------------------------------------------------------------------------

    The Battles Gas Plant was not shut down but under permit and in 
operation when the Clean Air Plan was adopted. EPA's emissions 
inventory guidelines and 15% rate-of-progress guidelines do not require 
that projected inventories eliminate emissions from sources that may be 
shut down in the future.6
---------------------------------------------------------------------------

    \6\ Indeed, Rate-of-Progress projected inventories generally 
should be based on allowable levels. See EPA's Emission Inventory 
Requirements for Ozone State Implementation Plans (EPA-450/4-91-
010), March 1991, pp. 36-7. Until permits are surrendered, sources 
should be assumed to be in operation.
---------------------------------------------------------------------------

    EPA is finalizing approval of the Santa Barbara emission 
inventories as meeting the requirements of section 182(a)(1) of the 
Act.

B. Control Measures

    EDC objected to the SBCAPCD's wholesale deletion of 1982 control 
measures, including measures which required development of rules 
incorporating the relative ozone formation potential of various 
emissions.
    In general, the 1994 SIP does not delete the 1982 SIP measures but 
rather updates them. EPA does not believe that the CAA requires the 
District to retain its prior commitments to develop reactivity-based 
rules, which are neither specifically mandated by the CAA nor 
associated with particular emission reductions or ambient air quality 
benefits in the 1982 SIP.
    EDC stated that the inadequacy of the SIP control measures is 
apparent, given Santa Barbara's violations of the ozone NAAQS. EPA 
interprets the comment as meaning that EDC does not believe that the 
control measures achieve sufficient emission reductions to attain the 
ozone NAAQS by 1996. The Agency is not addressing this issue because, 
as noted above, the State has withdrawn the attainment demonstration 
portion of the Santa Barbara plan. EPA is, however, approving the 
individual control measures in the SIP (1994 Clean Air Plan, Tables 4-2 
and 5-1) under the provisions of CAA sections 110(k)(3) and 301(a), 
because they strengthen the SIP.
    Table 5-1 of Santa Barbara's plan describes the area's 
transportation control measures (TCMs), which supersede the TCM list in 
the previously approved 1982 SIP. On May 1, 1995, EPA took direct final 
action to approve TCM-5, and to delete the Goleta Transit Center from 
the 1982 SIP (60 FR 21045). The 1994 Clean Air Plan shows that all of 
the 1982 TCMs have either been fully implemented or replaced by 1994 
TCMs.
    All non-transportation related control measures identified in the 
Santa Barbara Clean Air Plan have been fully adopted in regulatory 
form. If any of these regulations, which are assumed in the baseline of 
the Clean Air Plan, are relaxed or in practice achieve fewer emission 
reductions than relied upon in the SIP, the District must submit 
replacement rules on an expeditious schedule.
    Under sections 110(k)(3) and 301(a) of the Clean Air Act, EPA takes 
final action to approve the SIP control measures, including contingency 
measure T-21, because these measures strengthen the SIP.

C. ROP Provisions

    EPA is finalizing approval of the ROP plan as meeting the 15% ROP 
requirements of section 182(b)(1) of the Act. The ROP ROG targets, 
projected ROG emissions, and creditable ROG reductions are shown below 
in the table labeled ``Santa Barbara ROP Forecasts and Targets.'' 
Creditable emission reductions from fully adopted regulations reduce 
emissions below the ROP target level for 1996.

III. Summary of EPA Actions

    EPA approves the following elements of the 1994 California Ozone 
SIP for Santa Barbara, as meeting applicable CAA requirements:
    (1) Emission Inventories for Santa Barbara under section 182(a)(1) 
of the CAA.
    (2) 15% ROP Plan for Santa Barbara under section 182(b)(1).
    (3) Santa Barbara's control measures, including contingency measure 
T-21, under sections 110(k)(3) and 301(a) of the CAA.
    Nothing in this action should be construed as permitting or 
allowing or establishing a precedent for any future request for 
revision to any SIP. Each request for revision to the SIP shall be 
considered separately in light of specific technical, economic, and 
environmental factors and in relation to relevant statutory and 
regulatory requirements.

IV. Regulatory Process

A. Executive Order 12886

    This action has been classified as a Table 3 action for signature 
by the Regional Administrator under the procedures published in the 
Federal Register on January 19, 1989 (54 FR 2214-2225), as revised by a 
July 10, 1995 memorandum from Mary Nichols, Assistant Administrator for 
Air and Radiation. The Office of Management and Budget has exempted 
this regulatory action from Executive Order 12866 review.

B. Regulatory Flexibility Act

    Under the Regulatory Flexibility Act, 5 U.S.C. 600 et seq., 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, EPA may certify that the rule will not have a 
significant impact on a substantial number of small entities. Small 
entities include small business, small not-for-profit enterprises and 
government entities with jurisdiction over populations of less than 
50,000.
    SIP approvals under sections 110 and 301 and subchapter I, part D 
of the Clean Air Act, do not create any new requirements, but simply 
approve requirements that the State is already imposing. Therefore, 
because the

[[Page 1190]]

Federal SIP approval does not impose any new requirements, it does not 
have a significant impact on any small entities affected. Moreover, due 
to the nature of the Federal/state relationship under the Act, 
preparation of a regulatory flexibility analysis would constitute 
Federal inquiry into the economic reasonableness of state action. The 
Act forbids 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. 7410(a)(2).

C. Unfunded Mandates

    Under Section 202 of the Unfunded Mandates Reform Act of 1995 
(``Unfunded Mandates Act''), signed into law on March 22, 1995, EPA 
must prepare a budgetary impact statement to accompany any proposed or 
final rule that includes a Federal mandate that may result in estimated 
costs to State, local, or tribal governments in the aggregate; or to 
private sector, of $100 million or more. Under Section 205, EPA must 
select the most cost-effective and least burdensome alternative that 
achieves the objectives of the rule and is consistent with statutory 
requirements. Section 203 requires EPA to establish a plan for 
informing and advising any small governments that may be significantly 
or uniquely impacted by the rule.
    EPA has determined that the approval action promulgated does not 
include a Federal mandate that may result in estimated costs of $100 
million or more to either State, local, or tribal governments in the 
aggregate, or to the private sector. This Federal action approves pre-
existing requirements under State or local law, and imposes no new 
Federal requirements. Accordingly, no additional costs to State, local, 
or tribal governments, or to the private sector, result from this 
action.

D. Submission to Congress and the General Accounting Office

    Under section 801(a)(1)(A) of the Administrative Procedure Act 
(APA) as amended by the Small Business Regulatory Enforcement Fairness 
Act of 1996, EPA submitted a report containing this rule and other 
required information to the U.S. Senate, the U.S. House of 
Representatives and the Comptroller General of the General Accounting 
Office prior to publication of the rule in today's Federal Register. 
This rule is not a ``major rule'' as defined by section 804(2) of the 
APA as amended.

E. Petitions for Judicial Review

    Under section 307(b)(1) of the Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by March 10, 1997. Filing a 
petition for reconsideration by the Administrator of this final rule 
does not affect the finality of this rule for the purposes of judicial 
review nor does it extend the time within which a petition for judicial 
review may be filed, and shall not postpone the effectiveness of such 
rule or action. This action may not be challenged later in proceedings 
to enforce its requirements. (See section 307(b)(2).)
