EPA Proposes Prevention of Significant Deterioration and Title V Greenhouse Gas Tailoring Rule
Related Topics: Climate Change
EPA announced a proposal that is focused on large facilities emitting over 25,000 tons of greenhouse gases a year. These facilities would be required to obtain permits that would demonstrate they are using the best practices and technologies to minimize GHG emissions. The rule proposes new thresholds for GHG that define when CAA permits under the New Source Review (NSR) and title V operating permits programs would be required for new or existing industrial facilities, and (according to EPA) would cover nearly 70 percent of the national GHG emissions that come from stationary sources, including those from the nation’s largest emitters—including power plants, refineries, and cement production facilities.
Specifically, under the PSD program, EPA is attempting to raise the emissions threshold for applicability from 250 tons per year to 25,000 tons per year, but it is unclear if the agency has the legal authority to do so. Under the Title V operating permits program, EPA is proposing a major source emissions applicability threshold of 25,000 tons per year (tpy) of carbon dioxide CO2e (raised from 100 tpy) for existing industrial facilities. Facilities with GHG emissions below this threshold would not be required to obtain an operating permit. Comments were due December 28, and a final rule is expected by March 2010.
