BOSTON – Cherenzia Excavation Inc., of Westerly, will pay a penalty of $84,070 for alleged violations of the Clean Air Act and has taken steps to minimize emissions of hazardous air pollutants and visually test for dust under an agreement signed recently with the U.S. Environmental Protection Agency.
The settlement relates to the company’s two stone crushing and gravel processing plants at 64 Old Hopkinton Road and 109 White Rock Road. At the time of settlement, Cherenzia Excavation had come into compliance with two sets of federal Clean Air Act regulations, according to an EPA press release.
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, and they are all subject to the National Emission Standards for Hazardous Air Pollutants for stationary reciprocating internal combustion engines, the EPA said.
To come into compliance with federal clean air laws, Cherenzia Excavation installed pollution control equipment on three engines and completed initial performance tests to show that the engines met national emissions standards. Cherenzia Excavation replaced the remaining engine with a certified engine that meets EPA’s emission requirements.
Cherenzia Excavation will reduce emissions of hazardous air pollutants such as formaldehyde as a result of undertaking these steps.
Because Cherenzia Excavation also operates crushers, screeners and conveyor belts, it is subject to EPA’s New Source Performance Standards for Nonmetallic Mineral Processing Plants. Cherenzia Excavation came into compliance with this standard by performing required visible emissions testing for fugitive particulate matter, airborne dust that escapes from this processing machinery, and submitting overdue notifications for start-up of its operations.
