9VAC5-140 Regulation for Emissions Trading Programs , Virginia Register

Statutory Authority: §§ 10.1-1308 and 10.1-1322.3 of the Code of Virginia; §§ 108, 109, 110 and 302 of the Clean Air Act; 40 CFR Part 51.

1. The definitions of “CAIR NOx Annual Trading Program,” “CAIR NOx Ozone Season Trading Program,” “CAIR SO₂ Trading Program,” and “permitting authority” in 9VAC5-140-1020, 9VAC5-140-2020, and 9VAC5-140-3020 are amended to clarify that they are not intended to create trading programs only for sources geographically located within the borders of the Commonwealth of Virginia. Therefore, qualifying sources within the Commonwealth are to become full participants in the EPA-administered regional CAIR trading programs for annual NOx, ozone season NOx, and annual SO₂, along with sources permitted by authorities in all other states that are participating in the regional CAIR trading programs. The new language clarifies that the regulations should not be interpreted to limit the trading program to Virginia sources, which would be contrary to the intention that sources covered by other states’ approved CAIR rules or by the CAIR FIP may trade allowances with sources in the Commonwealth. In addition, the provisions of 9VAC5-140-1010, 9VAC5-140-2010, and 9VAC5-140-3010 are amended to reflect this clarification.

2. The definition of “most stringent state or federal NOx emissions limitation” in 9VAC5-140-1020, 9VAC5-140-2020, and 9VAC5-140-3020 is amended to clarify that the primary fuel, where it is not designated in the permit, is the fuel that would result in the lowest emission rate.

3. The definition of “cogeneration unit” in 9VAC5-140-1020, 9VAC5-140-2020, and 9VAC5-140-3020 is amended so that most units co-firing biomass will be exempt from CAIR. Specifically, the calculation methodology is removed for the efficiency standard in the cogeneration unit definition to exclude energy input from biomass making it more likely that units co-firing biomass are able to meet the efficiency standard and qualify for exemption from the rule. In these same sections, technical amendments were made to add a new definition of "biomass" and revise the definition of "total energy input."

Article 1
CAIR NO_x Annual Trading Program General Provisions

A. This part establishes general provisions and the designated representative, permitting, allowance, monitoring, and opt-in provisions for the State Clean Air Interstate Rule (CAIR) NO_X Annual Trading Program, under § 110 of the Clean Air Act (42 USC § 7410) and 40 CFR 51.123, as a means of mitigating interstate transport of fine particulates and nitrogen oxides.

B. The purpose of this part is not to create the CAIR NO_X Annual Trading Program only for CAIR NO_X units and CAIR NO_X sources geographically located within the borders of the Commonwealth of Virginia. Upon approval by EPA in accordance with 40 CFR 51.123 (o)(1) or (2), qualifying CAIR NO_X units and CAIR NO_X sources within the Commonwealth will become full participants in the EPA-administered regional CAIR NO_X Annual Trading Program, which will include CAIR NO_X units and CAIR NO_X sources permitted by authorities in all other states that are participating in the regional CAIR NO_X Annual Trading Program.

C. This part should not be interpreted to limit the CAIR NO_X Annual Trading Program to Virginia CAIR NO_X units and CAIR NO_X sources, which would be contrary to the intention that CAIR NO_X units and CAIR NO_X sources covered by CAIR programs of other states approved in accordance with 40 CFR 51.123 (o)(1) or (2) or by the CAIR Federal Implementation Plan (subparts AA through II of 40 CFR Part 97) may trade allowances with CAIR NO_X units and CAIR NO_X sources in the Commonwealth. While the CAIR NO_X Annual Trading Program must include CAIR NO_X units and CAIR NO_X sources and permitting authorities beyond the borders of the Commonwealth, the permitting authority for Virginia (the State Air Pollution Control Board) has no authority to ensure compliance with this part by any permitting authority, person or entity outside the Commonwealth.

D. The board has the authority under the Code of Virginia to regulate the allocations of allowances, issuance of the budget permits, the administration of the opt-in provisions and other duties assigned to the permitting authority only for CAIR NO_X units and CAIR NO_X sources in Virginia. The board authorizes the administrator to assist the board in implementing the CAIR NO_X Annual Trading Program by carrying out the functions set forth for the administrator in this part.

A. As used in this part, all words or terms not defined here shall have the meaning given them in ~~9VAC5 Chapter 10 (9VAC5-10),~~ 9VAC5-10 (General Definitions) unless otherwise required by context.

A. This part establishes general provisions and the designated representative, permitting, allowance, monitoring, and opt-in provisions for the State Clean Air Interstate Rule (CAIR) NO_X Ozone Season Trading Program, under § 110 of the Clean Air Act and 40 CFR 51.123, as a means of mitigating interstate transport of ozone and nitrogen oxides.

B. The purpose of this part is not to create the CAIR NO_X Ozone Season Trading Program only for CAIR NO_X Ozone Season units and CAIR NO_X Ozone Season sources geographically located within the borders of the Commonwealth of Virginia. Upon approval by EPA in accordance with 40 CFR 51.123 (o)(1) or (2), qualifying CAIR NO_X Ozone Season units and CAIR NO_X Ozone Season sources within the Commonwealth will become full participants in the EPA-administered regional CAIR NO_X Ozone Season Trading Program, which will include CAIR NO_X Ozone Season units and CAIR NO_X Ozone Season sources permitted by authorities in all other states that are participating in the regional CAIR NO_X Ozone Season Trading Program.

C. This part should not be interpreted to limit the CAIR NO_X Ozone Season Trading Program to Virginia CAIR NO_X Ozone Season units and CAIR NO_X Ozone Season sources, which would be contrary to the intention that CAIR NO_X Ozone Season units and CAIR NO_X Ozone Season sources covered by CAIR programs of other states approved in accordance with 40 CFR 51.123 (o)(1) or (2) or by the CAIR Federal Implementation Plan (subparts AA through II of 40 CFR Part 97) may trade allowances with CAIR NO_X Ozone Season units and CAIR NO_X Ozone Season sources in the Commonwealth. While the CAIR NO_X Ozone Season Trading Program must include CAIR NO_X Ozone Season units and CAIR NO_X Ozone Season sources and permitting authorities beyond the borders of the Commonwealth, the permitting authority for Virginia (the State Air Pollution Control Board) has no authority to ensure compliance with this part by any permitting authority, person or entity outside the Commonwealth.

D. The board has the authority under the Code of Virginia to regulate the allocations of allowances, issuance of the budget permits, the administration of the opt-in provisions and other duties assigned to the permitting authority only for CAIR NO_X Ozone Season units and CAIR NO_X Ozone Season sources in Virginia. The board authorizes the administrator to assist the board in implementing the CAIR NO_X Ozone Season Trading Program by carrying out the functions set forth for the administrator in this part.
