Attorney General Maura Healey announced Nov. 9 that Salisbury-based ENPRO Services, Inc. will pay a $150,000 fine to settle allegations that it treated hazardous waste without a license while claiming it was recycling the waste. ENPRO also was alleged to have improperly managed, treated, or labeled the hazardous waste it transported, stored, and handled, according to a statement from the attorney general’s office. In a consent judgment approved in Suffolk Superior Court, ENPRO was required to cease illegal treatment activities, bring practices into compliance, and submit to an independent audit of environmental management practices. The complaint alleges that since 2010, ENPRO collected, transported, and treated more than 140,000 gallons of gas and water mixtures at a facility on Parker Street in Newburyport. In a statement, Geoffrey Brown, ENPRO vice president, contendedthat none of the company’s actions caused harm to human health, the environment, or its customers, and “respectfully maintains that the MassDEP’s regulatory interpretations that are core to the allegations are counter to the original intent and common understanding of the US EPA and many other states, and in fact overregulate and discourage the environmentally beneficial goal of recycling gasoline.”David Rattigan can be reached at email@example.com.
