How often does the EPA review and approve Pennsylvania's emissions testing program?

The Environmental Protection Agency (EPA) conducts a review of state emissions testing programs, including Pennsylvania's, on an annual basis. This annual review is crucial for ensuring that the state's program is effectively controlling emissions in accordance with federal standards and regulations. It allows the EPA to assess whether Pennsylvania is meeting the requirements set by the Clean Air Act and to ensure that the methodologies and technologies used remain suitable and effective over time.

Regular annual reviews allow the EPA to quickly address any necessary updates or changes that may be required due to evolving environmental concerns, technological advancements, or changes in state-specific regulations. This frequency also reinforces the importance of compliance and accountability in maintaining air quality standards to protect public health and the environment.
