Basis: Section 10.1-1308 of the Virginia Air Pollution Control Law (§ 10.1-1300 et seq. of the Code of Virginia) authorizes the State Air Pollution Control Board to promulgate regulations abating, controlling, and prohibiting air pollution in order to protect public health and welfare. Section 10.1-1307.02 B of the Virginia Air Pollution Control Law establishes the requirement to develop a general permit for the construction or modification and operation of emergency generation sources during independent service operator (ISO) declared emergencies.

Federal Requirements: Section 110(a) of the Clean Air Act (CAA) mandates that each state adopt and submit to the Environmental Protection Agency (EPA) a plan that provides for the implementation, maintenance, and enforcement of each primary and secondary air quality standard within each air quality control region in the state. The state implementation plan shall be adopted only after reasonable public notice is given and public hearings are held. The plan shall include provisions to accomplish, among other tasks, the following:

1. Establish enforceable emission limitations and other control measures as necessary to comply with the provisions of the CAA, including economic incentives such as fees, marketable permits, and auctions of emissions rights;

2. Establish a program for the enforcement of the emission limitations and schedules for compliance; and

3. Establish programs for the regulation and permitting of the modification and construction of any stationary source within the areas covered by the plan to assure the achievement of the ambient air quality standards.

40 CFR Part 51 sets out requirements for the preparation, adoption, and submittal of state implementation plans. These requirements mandate that any such plan shall include several provisions as summarized below.

Subpart F (Procedural Requirements) specifies definitions of key terms, stipulations, and format for plan submission, requirements for public hearings, and conditions for plan revisions and federal approval.

Subpart G (Control Strategy) specifies the description of emissions reductions estimates sufficient to attain and maintain the standards, the description of control measures and schedules for implementation, time periods for demonstrations of the control strategy's adequacy, an emissions inventory, an air quality data summary, data availability, special requirements for lead emissions, stack height provisions, and intermittent control systems.

Subpart I (Review of New Sources and Modifications) specifies legally enforceable procedures, public availability of information on sources, identification of responsible agency, and administrative procedures.

Section 51.160 of Subpart I specifies that the plan must stipulate legally enforceable procedures that enable the permitting agency to determine whether the construction or modification of a facility, building, structure or installation, or combination of these will result in either a violation of any part of a control strategy or interference with attainment or maintenance of a national standard and, if such violation or interference would occur, the means by which the construction or modification can be prevented. The procedures must identify types and sizes of facilities, buildings, structures or installations which will be subject to review and discuss the basis for determining which facilities will be subject to review. The procedures must provide that owners of facilities, buildings, structures or installations must submit information on the nature and amounts of emissions and on the location, construction and operation of the facility. The procedures must ensure that owners comply with applicable control strategies after permit approval. The procedures must discuss air quality data and modeling requirements on which applications must be based.

Section 51.161 of Subpart I specifies that the permitting agency must provide opportunity for public comment on information submitted by owners and on the agency's analysis of the effect of construction or modification on ambient air quality, including the agency's proposed approval or disapproval. Section 51.161 also specifies the minimum requirements for public notice and comment on this information.

Section 51.162 of Subpart I specifies that the responsible agency must be identified in the plan.

Section 51.163 of Subpart I specifies that the plan must include administrative procedures to be followed in determining whether the construction or modification of a facility, building, structure or installation will violate applicable control strategies or interfere with the attainment or maintenance of a national standard.

Subpart L (Legal Authority) specifies identification of legal authority to implement plans and assignment of legal authority to local agencies.

Section 51.230 of Subpart L specifies that each state implementation plan must show that the state has the legal authority to carry out the plan, including the authority to perform the following actions:

1. Adopt emission standards and limitations and any other measures necessary for the attainment and maintenance of the national ambient air quality standards;

2. Enforce applicable laws, regulations, and standards, and seek injunctive relief;

3. Obtain information necessary to determine whether air pollution sources are in compliance with applicable laws, regulations, and standards, including authority to require recordkeeping and to make inspections and conduct tests of air pollution sources; and

4. Prevent construction, modification, or operation of a facility, building, structure, or installation, or combination thereof, which directly or indirectly results or may result in emissions of any air pollutant at any location which will prevent the attainment or maintenance of a national standard.

Section 51.231 of Subpart L requires the identification of legal authority as follows:

1. The provisions of law or regulation which the state determines provide the authorities required under 51.231 must be specifically identified, and copies of such laws or regulations must be submitted with the plan; and

2. The plan must show that the legal authorities specified in Subpart L are available to the state at the time of submission of the plan.

Purpose: The purpose of the regulation is to provide a streamlined process for permitting the construction or modification and operation of emergency generation sources during ISO-declared emergencies such that the emissions from the units in no way endanger the public health. The proposed general permit contains terms and conditions as may be necessary to form the legally enforceable basis for the implementation of all regulatory and statutory requirements applicable to new or modified emissions units that meet the requirements of emergency generation sources as required in § 10.1-1307.02 B of the Code of Virginia. Such sources are stationary internal combustion engines that operate according to the procedures in the ISO's emergency operations manual during an ISO-declared emergency.

Substance:

1. Definitions used in the regulation are identified.

2. General provisions are established that cover the overall basis, applicability, and general requirements of the general permit, circumvention, suspension or revocation, compliance authority, and enforcement of a general permit.

3. General permit administrative procedures are established for granting an authorization to operate under the general permit, applications for coverage under the general permit, required information for initial applications, authorization to operate, and transfer of authorization to construct and operate.

4. General permit terms and conditions are established. They include monitoring requirements, operating schedule, emissions limits for both compression ignition and spark ignition engines and for both attainment and nonattainment areas, testing requirements, recordkeeping and reporting requirements, and compliance and enforcement provisions.

Issues:

1. Public: The primary advantage to the public is a streamlined process for permitting the operation of emergency generation sources during ISO-declared emergencies. This will ensure that adequate electricity is available to commercial facilities and the citizens of Virginia during critical times when electrical demands may be significant. More stringent emission limits are established for units operating in nonattainment areas to ensure that the air quality impacts are mitigated.

2. Department: The benefit to the department will be a more efficient permitting process for emergency generation sources and a reduction in the number of permits that need to be modified or changed due to additions or changes at the facilities that are operating emergency generation sources during ISO-declared emergencies.

Summary:

Section 10.1-1307.02 B of the Code of Virginia mandates that the board develop a general permit for the use of back-up generation to authorize the construction, installation, reconstruction, modification, and operation of emergency generation sources during independent service operator (ISO) declared emergencies. It includes the definition of "emergency generation source" as a stationary internal combustion engine that operates according to the procedures in the ISO's emergency operations manual during an ISO-declared emergency. It includes emissions limits for both compression ignition (CI) and spark ignition (SI) emergency generation sources and provides more stringent emission limits for those sources operating in nonattainment areas (i.e., Northern Virginia) than for sources operating in attainment areas.

The regulation does not require any owner to apply for coverage under the general permit but provides the opportunity for an owner to apply for coverage if the source meets the requirements of the regulation.

"Spark ignition unit" or "SI unit" means a natural gas or liquefied petroleum gas fueled engine or any other type of engine with a spark plug (or other sparking device) and with operating characteristics significantly similar to the theoretical Otto combustion cycle. Spark ignition engines usually use a throttle to regulate intake air flow to control power during normal operation. Dual-fuel engines in which a liquid fuel (typically diesel fuel) is used for compression ignition and gaseous fuel (typically natural gas) is used as the primary fuel at an annual average ratio of less than 2 parts diesel fuel to 100 parts total fuel on an energy equivalent basis are spark ignition engines.

"Startup" means the date on which each affected unit completes the integration operational period, unless an extension for start-up notification as stated in subdivision 4 of 9VAC5-540-210 is approved by the department. An extension request must be submitted seven days prior to the end of the 30-day integration operational period.

"Virginia Air Pollution Control Law" means Chapter 13 (§ 10.1-1300 et seq.) of Title 10.1 of the Code of Virginia.
