The Environmental Protection Agency (EPA) is amending the emissions reporting regulations applicable to sources that monitor and report emissions under the Acid Rain Program, the Cross-State Air Pollution Rule (CSAPR), and/or the NOX SIP Call. The amendments provide that if an affected unit fails to complete a required quality-assurance, certification or recertification, fuel analysis, or emission rate test by the applicable deadline under the regulations because of travel, plant access, or other safety restrictions implemented to address the current COVID-19 national emergency and if the unit’s actual monitored data would be considered valid if not for the delayed test, the unit may temporarily continue to report actual monitored data instead of substitute data. Sources must maintain documentation, notify EPA when a test is delayed and later completed, and certify to EPA that they meet the criteria for using the amended reporting procedures.This action is necessary during the COVID-19 national emergency to protect onsite power plant operators and other essential personnel from unnecessary risk of exposure to the coronavirus. The amendments do not suspend emissions monitoring or reporting requirements or alter emissions standards under any program, and EPA expects the amendments not to cause any change in emissions levels.
