Approval and Promulgation of Air Quality Implementation Plans; 
Delaware; Reasonably Available Control Technology Under the 8-Hour 
Ozone National Ambient Air Quality Standard

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve a State Implementation Plan (SIP) 
revision submitted by the State of Delaware. This SIP revision pertains 
to the requirements in meeting the reasonably available control 
technology (RACT) under the 8-hour ozone national ambient air quality 
standard (NAAQS). These requirements are based on: Certification that 
previously adopted RACT controls in Delaware's SIP that were approved 
by EPA under the 1-hour ozone NAAQS are based on the currently 
available technically and economically feasible controls, and that they 
continue to represent RACT for the 8-hour implementation purposes; the 
adoption of new or more stringent regulations that represent RACT 
control levels; and a negative declaration that certain categories of 
sources do not exist in Delaware. This action is being taken under the 
Clean Air Act (CAA).

SUPPLEMENTARY INFORMATION: On October 2, 2006, the Delaware Department 
of Natural Resources and Environmental Control (DNREC) submitted a 
revision to its SIP that addresses the requirements of RACT under the 
8-hour ozone NAAQS. On October 5, 2006, DNREC submitted a supplement to 
this SIP revision.

I. Background

    Ozone is formed in the atmosphere by photochemical reactions 
between volatile organic compounds (VOC), oxides of nitrogen 
(NOX) and carbon monoxide (CO) in the presence of sunlight. 
In order to reduce ozone concentrations in the ambient air, the CAA 
requires all nonattainment areas to apply control on VOC/NOX 
emission sources to achieve emission reductions. Among effective 
control measures, RACT controls are a major group for reducing VOC and 
NOX emissions from stationary sources.
    RACT is defined as the lowest emission limitation that a particular 
source is capable of meeting by the application of control technology 
that is reasonably available considering technological and economic 
feasibility (44 FR 53761 at 53762, September 17, 1979). Section 182 of 
the CAA sets forth two separate RACT requirements for ozone 
nonattainment areas. The first requirement, contained in section 
182(a)(2)(A) of the CAA, and referred to as RACT fix-up requires the 
correction of RACT rules for which EPA identified deficiencies before 
the CAA was amended in 1990. Delaware has no deficiencies to correct 
under this section of the CAA. The second requirement, set forth in 
section 182(b)(2) of the CAA, applies to moderate (or worse) ozone 
nonattainment areas as well as to marginal and attainment areas in 
ozone transport regions (OTRs) established pursuant to section 184 of 
the CAA, and requires these areas to implement RACT controls on all 
major VOC and NOX emission sources and on all sources and 
source categories covered by a control technique guideline (CTG) issued 
by EPA.
    Under the 1-hour ozone NAAQS, Kent and New Castle Counties in 
Delaware were designated part of a severe ozone nonattainment area, and 
Sussex County was designated as a marginal ozone nonattainment area 
located in an OTR. Therefore, all three counties were subject to RACT 
requirements under the 1-hour ozone standard. Since the early 1990s, 
Delaware implemented numerous RACT controls throughout the State to 
meet the CAA RACT requirements. These RACT controls were promulgated in 
the Delaware Air Pollution Control Regulation No. 24 for VOC sources 
and Regulation No. 12 for NOX sources.
    Under the 8-hour ozone NAAQS, the entire State of Delaware (Kent, 
New Castle and Sussex Counties) is a part of the Philadelphia moderate 
nonattainment area, and is therefore subject to the CAA requirements. 
Delaware is required to submit to EPA a SIP revision that addresses how 
Delaware meets the RACT requirements under the 8-hour ozone standard. 
The entire State of Delaware is also part of the OTR established under 
section 184 of the CAA.
    EPA requires under the 8-hour ozone NAAQS that states meet the CAA 
RACT requirements, either through a certification that previously 
adopted RACT controls in their SIP revisions approved by EPA under the 
1-hour ozone NAAQS represent adequate RACT control levels for 8-hour 
attainment purposes, or through the adoption of new or more stringent 
regulations that represent RACT control levels. A certification must be 
accompanied by appropriate supporting information such as consideration 
of information received during the public comment period and 
consideration of new data. This information may supplement existing 
RACT guidance documents that were developed for the 1-hour standard, 
such that the State's SIP accurately reflects RACTs for the 8-hour 
ozone standard based on the current availability of technically and 
economically feasible controls. Adoption of new RACT regulations will 
occur when states have new stationary sources not covered by existing 
RACT regulations, or when new data or technical information indicates 
that a previously adopted RACT measure does not represent a newly 
available RACT control level. Another 8-hour ozone NAAQS requirement 
for RACT is to submit a negative declaration that there are no CTG or 
non-CTG major sources of VOC and NOX emissions within 
Delaware.

II. Summary of SIP Revision

    Delaware's SIP revision contains the requirements of RACT set forth 
by the CAA under the 8-hour ozone NAAQS. Delaware's SIP revision 
satisfies the 8-hour RACT requirements through (1) certification that 
previously adopted RACT controls in Delaware's SIP that were approved 
by EPA under the 1-hour ozone NAAQS are based on the currently 
available technically and economically feasible controls, and continues 
to represent RACT for the 8-hour implementation purposes; (2) the 
adoption of new or more stringent regulations that represent RACT 
control levels; and (3) a negative declaration that certain CTG or non-
CTG major sources of VOC and NOX sources do not exist in 
Delaware.

VOC RACT Controls

    Delaware Air Pollution Control Regulation No. 1124 (formerly 
Regulation 24) contains Delaware's VOC RACT controls that were 
implemented and approved in the Delaware SIP under the 1-hour ozone 
NAAQS.
    Table 1 lists Delaware's VOC RACT controls.

    Delaware adopted a new VOC RACT control for lightering operations 
(Section 46) and submitted it to EPA as a SIP revision. EPA approved 
this VOC RACT on September 13, 2007 (72 FR 52285) with an effective 
date of October 15, 2007.
    Delaware also submitted a negative declaration that the following 
VOC CTG or non-CTG major sources do not exist in Delaware: Manufacture 
of pneumatic rubber tires; wood furniture manufacturing operations; and 
shipbuilding and ship repair operations (surface coating).

NOX RACT Controls

    Delaware Air Pollution Control Regulation No. 12 contains 
Delaware's NOX RACT controls that were implemented and 
approved into the Delaware SIP under the 1-hour ozone NAAQS.

III. Proposed Action

    EPA is proposing to approve the Delaware SIP revision that 
addresses the requirements of RACT under the 8-hour ozone NAAQS. 
Delaware submitted this SIP revision on October 2, 2006 and a 
supplement submittal on October 5, 2006. This SIP revision is based on 
a combination of (1) certification that previously adopted RACT 
controls in Delaware's SIP that were approved by EPA under the 1-hour 
ozone NAAQS are based on the currently available technically and 
economically feasible controls, and that they continue to represent 
RACT for the 8-hour implementation purposes; (2) the adoption of new or 
more stringent regulations that represent RACT control levels; and (3) 
the negative declaration that there are no CTG or non-CTG major sources 
of VOC and NOX emissions within Delaware. EPA is soliciting 
public comments on the issues discussed in this document. These 
comments will be considered before taking final action.

IV. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the CAA 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 of the Clean Air Act. Accordingly, 
this action merely proposes to approve state law as meeting Federal 
requirements and does not impose additional requirements beyond those 
imposed by state law. For that reason, this proposed action:
     Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Order 
12866 (58 FR 51735, October 4, 1993);
     Does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     Does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Pub. L. 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);
     Is not subject to requirements of Section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the CAA; 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 proposed rule, pertaining to the Delaware RACT 
under the 8-hour ozone NAAQS, 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.
