PSD Greenhouse Gas PSD Greenhouse Gas Tailoring RuleTailoring Rule
The rule proposes new thresholds for greenhouse The rule proposes new thresholds for greenhouse gas emissions (GHG) that define when Clean Air Act gas emissions (GHG) that define when Clean Air Act (CAA) permits under the New Source Review (NSR) (CAA) permits under the New Source Review (NSR) and Title V operating permits programs would be and Title V operating permits programs would be required for new or existing facilities required for new or existing facilities
Under the Title V operating permits program, EPA is proposing a Under the Title V operating permits program, EPA is proposing a major source applicability threshold of 25,000 tpy CO2e for major source applicability threshold of 25,000 tpy CO2e for existing facilities existing facilities
Under the Prevention of Significant Deterioration (PSD) portion of Under the Prevention of Significant Deterioration (PSD) portion of NSR—EPA is proposing a major stationary source threshold of NSR—EPA is proposing a major stationary source threshold of 25,000 tpy CO2e, and a significance level between 10,000 and 25,000 tpy CO2e, and a significance level between 10,000 and 25,000 tpy CO2e. 25,000 tpy CO2e.
