I. Background

The Commonwealth of Virginia submitted a formal revision on April 26, 2004 and a supplemental submittal on August 18, 2004 to its State Implementation Plan (SIP). The SIP revision consists of a RACT determination, contained in the permit to operate, for the control of NOX from Washington Gas Company, Ravensworth Station, Registration No. 72277, located in Fairfax County, Virginia.

II. Summary of SIP Revision

Washington Gas Company, Ravensworth Station, Registration No. 72277

The Washington Gas Company owns and operates a peak shaving, propane storage facility in Springfield, Virginia (the Ravensworth Station). VADEQ submitted a permit to operate for Washington Gas Company to implement RACT requirements for ten (10) natural gas-fired, Ingersoll Rand Model engine-driven compressors, one natural gas-fired Caterpillar model electrical generator, three (3) natural gas-fired Erie City boilers, and one natural gas-fired Cleaver Brooks boiler.

Emissions Controls

The NOX emissions from each of the compressor engines shall be controlled by a combination of engine tuning and good combustion practices. Good combustion practices shall involve the continuous operation of the engines at optimum performance by maintaining operating parameters within ranges established during tuning and performance testing events, which will reduce NOX emissions. Prior to the tuning events, Washington Gas Company shall develop a tuning plan, which describes the activity to be involved in the tuning event. The plan shall provide the rationale for optimizing specific parameters and their significance in reducing NOX. The plan shall be submitted to VADEQ at least 30 days prior to the performance test. NOX emissions from the compressor engines, boilers and Caterpillar generator shall be controlled by proper operation and maintenance. Operators shall be trained in the proper operation of all such equipment. Washington Gas Company shall maintain records of the required training including a statement of time, place and nature of training provided. The gas company shall have available good written operating procedures and a maintenance schedule. These procedures shall be based on the manufacturer's recommendations, at minimum. All records required by this condition shall be kept on site and made available for inspection by VADEQ.

Emissions Limitations

A NOX emission limit for each compressor engine will be established based on the results of the performance tests. The emission limits based on the performance test required, each compressor engine shall be operated and maintained in accordance with the manufacturers' specifications and, to the extent practicable, in manner consistent with good air pollution control practices for minimizing emissions. NOX emissions from each boiler shall not exceed 0.20 lbs/MMBtu. NOX emissions from the Caterpillar generator shall not exceed 1.5 g/bhp-hr.


The gas company shall conduct two sets of performance tests to measure NOX emissions in the exhaust stack of one of each model of compressor engine. The first set of tests, to be conducted prior to the tuning event, shall be for the purpose of establishing a baseline NOX emission rate for each unit tested. The second set of tests, to be conducted following the tuning event, shall be used to evaluate the effectiveness of the tuning event and to correlate specific engine operating parameters to emissions. The gas company shall submit an original and one copy of a test protocol at least 30 days prior to testing. Copies of the test results shall be submitted to VADEQ within 45 days after test completion. The gas company shall also prepare a report, which provides the parametric data collected, the correlation to NOX emissions, and the selection of appropriate operating ranges to each operating parameter. The report shall be submitted to VADEQ along with the test report. The gas company shall perform tests to measure NOX emissions in the exhaust stack of two of four boilers to demonstrate compliance with the emission limit. The gas company shall submit a copy of the test protocol at least 30 days prior to testing. The test results shall be submitted to VADEQ within 45 days after test completion and shall conform to the test report format.

On Site Records

The gas company shall maintain records of emission data and operating parameters as necessary to demonstrate compliance with this permit. These records shall include, but are not limited to the following:

a. The tuning plan.

b. The report detailing results of the tuning event, the parametric data collected, the correlation of operating parameters to emissions, and the selection of operating ranges of the parameters.

c. The performance test reports for the compressor engines, including the results of both pre- and post-tuning.

d. The performance test report for the boilers.

e. Records of compressor engine, boiler and Caterpillar generator operator training, maintenance schedules and record of maintenance performed.

These records shall be available for inspection by VADEQ and shall be current for the most recent five years.

III. EPA's Evaluation of the SIP Revisions

EPA is approving this SIP submittal because the Commonwealth established and imposed requirements in accordance with the criteria set forth in SIP-approved regulations for imposing RACT. The Commonwealth has also imposed record-keeping, monitoring, and testing requirements on these sources sufficient to determine compliance with these requirements.

IV. General Information Pertaining to SIP Submittals From the Commonwealth of Virginia

In 1995, Virginia adopted legislation that provides, subject to certain conditions, for an environmental assessment (audit) “privilege” for voluntary compliance evaluations performed by a regulated entity. The legislation further addresses the relative burden of proof for parties either asserting the privilege or seeking disclosure of documents for which the privilege is claimed. Virginia's legislation also provides, subject to certain conditions, for a penalty waiver for violations of environmental laws when a regulated entity discovers such violations pursuant to a voluntary compliance evaluation and voluntarily discloses such violations to the Commonwealth and takes prompt and appropriate measures to remedy the violations. Virginia's Voluntary Environmental Assessment Privilege Law, Va. Code sec. 10.1-1198, provides a privilege that protects from disclosure documents and information about the content of those documents that are the product of a voluntary environmental assessment. The Privilege Law does not extend to documents or information (1) that are generated or developed before the commencement of a voluntary environmental assessment; (2) that are prepared independently of the assessment process; (3) that demonstrate a clear, imminent and substantial danger to the public health or Start Printed Page 59814environment; or (4) that are required by law.

On January 12, 1998, the Commonwealth of Virginia Office of the Attorney General provided a legal opinion that states that the Privilege law, Va. Code sec. 10.1-1198, precludes granting a privilege to documents and information “required by law,” including documents and information “required by Federal law to maintain program delegation, authorization or approval,” since Virginia must “enforce Federally authorized environmental programs in a manner that is no less stringent than their Federal counterparts * * *.” The opinion concludes that “[r]egarding § 10.1-1198, therefore, documents or other information needed for civil or criminal enforcement under one of these programs could not be privileged because such documents and information are essential to pursuing enforcement in a manner required by Federal law to maintain program delegation, authorization or approval.”

Virginia's Immunity law, Va. Code sec. 10.1-1199, provides that “[t]o the extent consistent with requirements imposed by Federal law,” any person making a voluntary disclosure of information to a State agency regarding a violation of an environmental statute, regulation, permit, or administrative order is granted immunity from administrative or civil penalty. The Attorney General's January 12, 1998 opinion states that the quoted language renders this statute inapplicable to enforcement of any federally authorized programs, since “no immunity could be afforded from administrative, civil, or criminal penalties because granting such immunity would not be consistent with Federal law, which is one of the criteria for immunity.”

Therefore, EPA has determined that Virginia's Privilege and Immunity statutes will not preclude the Commonwealth from enforcing its program consistent with the Federal requirements. In any event, because EPA has also determined that a state audit privilege and immunity law can affect only State enforcement and cannot have any impact on Federal enforcement authorities, EPA may at any time invoke its authority under the Clean Air Act, including, for example, sections 113, 167, 205, 211 or 213, to enforce the requirements or prohibitions of the State plan, independently of any State enforcement effort. In addition, citizen enforcement under section 304 of the Clean Air Act is likewise unaffected by this, or any, State audit privilege or immunity law.

V. Final Action

EPA is approving revisions to the Commonwealth of Virginia's SIP which establish and require NOX RACT for Washington Gas Company, Ravensworth Station, located in Fairfax County, Virginia. EPA is publishing this rule without prior proposal because the Agency views this as a noncontroversial amendment and anticipates no adverse comment. However, in the “Proposed Rules” section of today's Federal Register, EPA is publishing a separate document that will serve as the proposal to approve the SIP revision if adverse comments are filed. This rule will be effective on December 6, 2004 without further notice unless EPA receives adverse comment by November 5, 2004. If EPA receives adverse comment, EPA will publish a timely withdrawal in the Federal Register informing the public that the rule will not take effect. EPA will address all public comments in a subsequent final rule based on the proposed rule. EPA will not institute a second comment period on this action. Any parties interested in commenting must do so at this time.

VI. Statutory and Executive Order Reviews

A. General Requirements

Under Executive Order 12866 (58 FR 51735, October 4, 1993), this 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 FR 28355, May 22, 2001). This action merely approves State law as meeting Federal requirements and imposes no additional requirements beyond those imposed by State law. Accordingly, the Administrator certifies that this 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 approves 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 (Pub. L. 104-4). This rule also does not have tribal implications because it will 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). This action also does not have federalism implications because it does not 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). This action merely approves a State rule implementing a Federal standard, and does not alter the relationship or the distribution of power and responsibilities established in the Clean Air Act. This rule also is not subject to Executive Order 13045 “Protection of Children from Environmental Health Risks and Safety Risks” (62 FR 19885, April 23, 1997), because it is not economically significant.

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. This rule does not impose an information collection burden under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).

B. Submission to Congress and the Comptroller General

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 of the rule, to each House of the Congress and to the Comptroller General of the United States. Section 804 exempts from section 801 the following types of rules: (1) Rules of particular applicability; (2) rules relating to agency management or personnel; and (3) rules of agency organization, procedure, or practice that do not substantially affect the rights or obligations of non-agency parties. 5 U.S.C. 804(3). EPA is not required to submit a rule report Start Printed Page 59815regarding today's action under section 801 because this is a rule of particular applicability establishing source-specific requirements for Washington Gas Company, Ravensworth Station, located in Fairfax County, Virginia.

C. 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 December 6, 2004. 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, pertaining to the NOX RACT for Washington Gas Company, Ravensworth Station, located in Fairfax County, Virginia, may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)
