EPA is stuck between a rock and a hard place in using the Clean Air Act to regulate greenhouse gas emissions. Having made an endangerment finding and issued final motor vehicle regulations, EPA soon (commencing January 2, 2011) must implement its Prevention of Significant Deterioration (PSD) preconstruction review program for stationary sources as one or more greenhouse gases become “regulated pollutants” under the statute. But the PSD program is hardly an ideal tool for the job, and may indeed be one of the worst.
Recognizing the difficulty of its task, in late 2009 EPA commissioned a Climate Change Work Group to advise it regarding how best to implement the PSD permit program and how to define Best Available Control Technology (BACT) for sources of greenhouse gas emissions. This January the Work Group issued a Phase One report that contained some important but relatively basic recommendations.
Now the Agency has launched Phase Two of the Work Group effort. In an April 9 letter to Work Group Co-Chairs, EPA Assistant Administrator Gina McCarthy asked the Work Group to focus on two of the most important strategies for reducing greenhouse gas emissions – energy efficiency and innovation.
Most seasoned observers recognize that the PSD process currently discourages energy efficiency investments. That is because PSD rules assume that more efficient units will be used more and that such projects could cause net emission increases that trigger PSD review and require the installation of BACT. The PSD process thus significantly delays and adds cost to many energy efficiency projects. As a result, many efficiency upgrades are foregone for fear that they will trigger the PSD process. This is tragic because efficiency upgrades offer the greatest potential for near-term and cost-effective greenhouse gas reductions. See, e.g., Unlocking Energy Efficiency in the U.S. Economy (July 2009).
The Work Group’s task of encouragingenergy efficiency by using the instrument most responsible for chilling such investments is the policy equivalent of placing a square peg into a round hole. If the Work Group recommends expediting or exempting from PSD review appropriate efficiency projects, then there is some hope that EPA can use the program to capture as-yet-untapped efficiency and innovation opportunities that currently exist. If, on the other hand, the Work Group, and ultimately EPA, remain unwilling to clear the regulatory costs and hurdles that PSD customarily imposes, then the opportunity will be lost.
EPA has asked the Work Group to provide its recommendations by no later than mid July. So stay tuned.
