How often does the Pennsylvania Department of Environmental Protection conduct reviews of emissions regulations?

The Pennsylvania Department of Environmental Protection conducts reviews of emissions regulations regularly, which typically occur annually or in response to significant changes in federal law. This practice ensures that state regulations remain aligned with federal standards and incorporate the latest scientific knowledge, technological advancements, and environmental policies.

Conducting these reviews on an annual basis allows the department to keep up with evolving environmental conditions and compliance requirements, ultimately focusing on enhancing air quality and protecting public health. Responding to changes in federal law is equally important, as it helps the state maintain regulatory consistency and avoid discrepancies that could affect both enforcement and compliance by emissions sources.

In contrast, conducting reviews daily or monthly would not be practical or necessary due to the time and resources required for thorough evaluations. A five-year review cycle may not be frequent enough to stay current with rapidly changing environmental regulations and scientific understanding.
