Hanover Insurance Group Inc. has been fined $6,004 by the Massachusetts Department of Environmental Protection (MassDEP) for air pollution control, hazardous waste and underground storage violations at its Lincoln Street office in Worcester.

During a routine inspection December 2012, MassDEP determined that the company failed to properly record and monitor air pollution control data from its emergency backup engines, register its waste oil status with MassDEP and comply with numerous underground storage tank requirements at its office at 440 Lincoln St. A notice of non-compliance (NON) was issued for those violations in March 2013.

During a follow-up inspection in December 2013, MassDEP found the company was still non-compliant with the citations listed in the original NON and other violations were found. In a recent consent order, the company, which has since corrected the violations, has agreed to maintain compliance and pay the penalty.

The penalty will be used to complete an energy-related Supplemental Environmental Project (SEP) that will benefit the Boys and Girls Club at the city of Worcester’s Great Brook Valley public housing complex. The SEP will include an energy audit and follow-up review, installation of energy-efficient lighting and installation of reflective window film. The company will also provide youth members with information about the impact of these improvements on everyday use and the importance of energy efficiency. The cost to complete the SEP work is estimated at between $7,500 and $9,000.

"The company has taken steps to ensure its future compliance with environmental regulations," Lee Dillard Adams, director of MassDEP’s central regional office in Worcester, said in a statement. "The SEP will result in improved energy efficiency for the Boys and Girls Club and great educational opportunities for youths from the city."
