Rhode Island crushing and demolition firm to pay Clean Air Act violation penalty

Cherenzia Excavation Inc., Westerly, Rhode Island, has taken steps to help minimize emissions of hazardous air pollutants and visually test for dust under an agreement signed recently with the U.S. Environmental Protection Agency (EPA).

According to the settlement, the company also is required to pay a penalty of $84,070 for its alleged violations of the Clean Air Act. The settlement relates to the company’s two stone crushing and gravel processing plants.

Cherenzia Excavation uses three stationary diesel engines/generators at its Old Hopkinton Road facility, and one stationary diesel engine/generator at its White Rock Road facility.

To come into compliance with federal clean air laws, the company installed pollution control equipment on three of the engines and completed initial performance tests to demonstrate that the engines met the national emissions standards.

Cherenzia Excavation replaced the remaining engine with a certified engine that meets EPA’s emission requirements.
