Marlborough’s Allegro MicroSystems, LLC was penalized $9,503 by the state Department of Environmental Protection for violating hazardous waste regulations at its former facility in Worcester.

MassDEP’s inspection of the company’s microchip manufacturing plant in December confirmed a report from Allegro to the MassDEP’s emergency response hotline. The call stated that Allegro had emptied containers of surplus acids down the drain into the municipal sewer system while in the process of closing the facility.

MassDEP also found other violations including discharging hazardous process wastewaters down the drain, failure to post complete emergency response postings, and failure to characterize waste and properly label a waste oil container.

“The proper handling and disposal of hazardous waste is one of the tenets of environmental protection” said Mary Jude Pigsley, director of MassDEP’s Central Regional Office in Worcester. “It is fortunate that there were no impacts to the sewer system or personnel as a result of this episode. The company self-reported the illegal disposal and has implemented measures to ensure similar violations do not occur again.”

Allegro corrected the violations at the new facility in Marlborough.

The company sold the building last month to Worcester-based property developers Chacharone Properties for $3.9 million.
