| 05-20983 | Prevention of Significant Deterioration, Nonattainment New Source Review, and New Source Performance Standards: Emissions Test for Electric Generating Units | Proposed Rule | The EPA (we) is proposing to revise the emissions test for existing electric generating units (EGUs) that are subject to the regulations governing the Prevention of Significant Deterioration (PSD) and nonattainment major New Source Review (NSR) programs (collectively "NSR") mandated by parts C and D of title I of the Clean Air Act (CAA or Act). The revised emissions test is the same as that in the New Source Performance Standards (NSPS) program under CAA section 111(a)(4). For existing EGUs, we are proposing to compare the maximum hourly emissions achievable at that unit during the past 5 years to the maximum hourly emissions achievable at that unit after the change to determine whether an emissions increase would occur. Alternatively, we are soliciting public comment on a major NSR emissions test for existing EGUs that would compare maximum hourly emissions achieved before a change to the maximum hourly emissions achieved after the change. We are also soliciting public comment on adopting an NSR emissions test based on mass of emissions per unit of energy output. In addition, we are soliciting comment on whether to revise the NSPS regulations to include a maximum achieved emissions test or an output- based emissions test, either in lieu of or in addition to the maximum achievable hourly emissions test. Today's proposal would not affect new EGUs, which would continue to be subject to major NSR preconstruction review and to the NSPS program. The proposed rule would only apply prospectively to changes at existing EGUs potentially covered by major NSR and the NSPS programs. These proposed regulations interpret CAA section 111(a)(4), in the context of NSR and NSPS, for physical changes and changes in the method of operation at existing EGUs. The proposed regulations would establish a uniform emissions test nationally under the NSPS and NSR programs for existing EGUs. The proposed regulations would also promote the safety, reliability, and efficiency of EGUs. | 2005-10-20 | 2005 | 10 | https://www.federalregister.gov/documents/2005/10/20/05-20983/prevention-of-significant-deterioration-nonattainment-new-source-review-and-new-source-performance | https://www.govinfo.gov/content/pkg/FR-2005-10-20/pdf/05-20983.pdf | Environmental Protection Agency | 145 | The EPA (we) is proposing to revise the emissions test for existing electric generating units (EGUs) that are subject to the regulations governing the Prevention of Significant Deterioration (PSD) and nonattainment major New Source Review (NSR)... |
