On February 13, the Department of Environmental Protection presented its preliminary draft proposed rulemaking to establish a carbon dioxide budget trading program to the Air Quality Technical Advisory Committee (AQTAC). The proposed trading program would apply to fossil fuel fired electricity generators of greater than 25 MW in Pennsylvania. The draft proposal reflects a first look at DEP’s vision for a cap-and-trade program as directed by Governor Tom Wolf’s October 3, 2019, Executive Order 2019-07.
The draft proposed rule, although still in development, parallels the model rule prescribed by the Regional Greenhouse Gas Initiative (RGGI). RGGI is a coalition of 10 states in the Northeast and Mid-Atlantic that participate in a regional CO2 cap-andtrade program for fossil fuel-fired electricity generating units that have a nameplate capacity of over 25 MWe.
Under the program, each member state has a budget of CO2 allowances, which it then allocates through setaside programs, offsets or periodic auctions. The number of allowances in each state’s CO2 budget that are allocated through auction varies widely among members. Each affected source (CO2 budget source) is required to hold sufficient CO2 allowances based on its CO2 emissions as determined from continuous monitoring. Each allowance is equal to one ton of CO2 emissions.
States’ CO2 budgets, and in turn available allowances, periodically reduce over time. This requires each CO2 budget source to either reduce CO2 emissions as measured by continuous monitoring, or obtain extra CO2 allowances to cover its emissions in excess of its allowance account. Under RGGI, auctions to obtain allowances generally occur quarterly, and may be open to qualified participants other than CO2 budget sources. The draft proposed rule explicitly mentions financial institutions and environmental groups as potential auction participants. The proposal specifies an annual rather than quarterly auction process.
Unlike the majority of RGGI state members, Pennsylvania DEP has indicated it does not intend to seek legislative authority to implement a CO2 trading program, but rather believes it has sufficient authority under the Pennsylvania Air Pollution Control Act. This position has been controversial, as some stakeholders contend that approval by the Pennsylvania General Assembly is necessary for such a trading program, including one that would involve other states. In November 2019, bills were introduced into the House (HB 2025) and Senate (SB 950) that would require General Assembly approval for any Pennsylvania carbon cap-and-trade program. This legal dispute is likely to give rise to significant ongoing challenges to the trading program rule.
DEP’s draft proposed rule contains a number of differences from the RGGI model rule, most notably including:
- The proposed rule states that it is designed to reduce CO2 emissions “in a manner that is protective of public health, welfare and the environment and is economically efficient,” while the RGGI model rule mentions only economic efficiency in its statement of purpose. Numerous concerns were raised at the AQTAC meeting regarding the overall cost-effectiveness of the trading program, an analysis of which will be required under Pennsylvania’s Regulatory Review Act, Commonwealth Attorneys Act and the Climate Change Act. DEP indicated it is still assessing costs and benefits of the trading program. The overall economic impact of the regulation will be a critical issue to a variety of stakeholders as the rulemaking progresses.
- The draft proposed rule does not require the establishment of multi-state allowance auctions, as performed within RGGI. Rather, the draft proposal gives DEP discretion to hold auctions only within Pennsylvania if it determines, among other things, that its participation in a multi-state auction process would not provide more benefits than costs to Pennsylvania versus a statewide auction. There is no established timeframe in the draft proposed rule for Pennsylvania DEP to determine which approach it will take.
DEP is operating on an accelerated timeframe to initiate and ultimately finalize the CO2 budget trading program rulemaking. It intends to present a proposed version of the regulation to AQTAC in April, at which point the committee will vote on whether to advance the proposal to the Environmental Quality Board (EQB). DEP anticipates submitting the proposal to the EQB by July as required by Executive Order 2019-07. Assuming the EQB votes to adopt the regulation as a proposed rulemaking, public comments will be solicited in fall of 2020, and the final rulemaking could be promulgated by fall 2021. DEP expects the regulation to be effective in the first quarter of 2022.
Owners and operators of fossil fuel-fired electricity generating units greater than 25MW will be directly affected by the CO2 budget trading program rulemaking if the rule is adopted in its currently proposed form. In addition, the energy industry, manufacturers and consumers in general are likely to be affected by the rulemaking based on the potentially far-reaching impacts to the nature of energy generation within Pennsylvania and regionally.
