SUPPLEMENTARY INFORMATION:  

I.  Background

On November 1, 2007, the Delaware Department of Natural Resources and
Environmental Control (DNREC) submitted a SIP revision for Regulation
No. 1144 – Control of Stationary Generator Emissions.  The SIP
revision applies to new, existing, emergency, and distributed stationary
generators.

II.  Summary of SIP Revision

Regulation No. 1144 will impact any owner of a stationary generator,
except the owner of any of the following:  mobile generator; residential
generator for emergency power use only; certain generators whose
emissions are already controlled; or generators with a standby power
rating of ten kilowatts or less.  Regulation No. 1144 establishes
operating requirements, fuel sulfur content limits, and record keeping
requirements for stationary generators.  The regulation will also 

require stationary generators which operate at times other than during
emergencies for testing or for maintenance to meet certain emission
standards to reduce their emissions.

III.  Proposed Action

EPA is proposing to approve the Delaware SIP revision for Regulation No.
1144 – Control of Stationary Generator Emissions submitted on November
1, 2007.  This regulation will help ensure that the air emissions from
new and existing stationary generators do not cause or contribute to the
existing air quality problems with regard to ground-level ozone and fine
particulate matter, thereby adversely impacting public health, safety
and welfare.  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 Executive Order 12866 (58 FR 51735, October 4, 1993), this
proposed action is not a "significant regulatory action" and therefore
is not subject to review by the Office of 

Management and Budget.  For this reason, this action is also not subject
to Executive Order 13211, "Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use"  (66 Fed. Reg.
28355 (May 22, 2001)).  This action merely proposes to approve state law
as meeting Federal requirements and imposes no additional requirements
beyond those imposed by state law.  Accordingly, the Administrator
certifies that this proposed rule will not have a significant economic
impact on a substantial number of small entities under the Regulatory
Flexibility Act (5 U.S.C. 601 et seq.).  Because this rule proposes to
approve pre-existing requirements under state law and does not impose
any additional enforceable duty beyond that required by state law, it
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).  This proposed rule also does not have a
substantial direct effect on one or more Indian tribes, on the
relationship between the Federal Government and Indian tribes, or on the
distribution of power and responsibilities between the Federal
Government and Indian tribes, as specified by Executive Order 13175 (65
FR 67249, November 9, 2000), nor will it have substantial direct effects
on the States, on the relationship between the national government and
the States, or on the distribution of power and responsibilities among
the various levels of government, as specified in Executive Order 13132
(64 FR 43255, August 10, 1999), because it merely proposes to approve a
state rule implementing a Federal requirement, and does not alter the
relationship or the distribution of power and responsibilities
established in the Clean Air Act. This proposed rule also is not subject
to Executive Order 13045 (62 FR 19885, April 23, 1997), because it
approves a state rule implementing a Federal standard.  

In reviewing SIP submissions, EPA(s role is to approve state choices,
provided that they meet the criteria of the Clean Air Act.  In this
context, in the absence of a prior existing requirement for 

the State to use voluntary consensus standards (VCS), EPA has no
authority to disapprove a SIP submission for failure to use VCS.  It
would thus be inconsistent with applicable law for EPA, when it reviews
a SIP submission, to use VCS in place of a SIP submission that otherwise
satisfies the provisions of the Clean Air Act.  Thus, the requirements
of section 12(d) of the National Technology Transfer and Advancement Act
of 1995 (15 U.S.C. 272 note) do not apply.  As required by section 3 of
Executive Order 12988 (61 FR 4729, February 7, 1996), in issuing this
proposed rule, EPA has taken the necessary steps to eliminate drafting
errors and ambiguity, minimize potential litigation, and provide a clear
legal standard for affected conduct.  EPA has complied with Executive
Order 12630 (53 FR 8859, March 15, 1988) by examining the takings
implications of the rule in accordance with the (Attorney General(s
Supplemental Guidelines for the Evaluation of Risk and Avoidance of
Unanticipated Takings( issued under the executive order.  This proposed
rule pertaining to Delaware’s control of stationary generator
emissions, does not impose an information collection burden under the
provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et
seq.).
