Environmental Alert

On February 13, 2020, the Pennsylvania 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 Pennsylvania 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-and-trade 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 set-aside 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 sources”) 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. …
