SOUTH PORTLAND — A chemical plant could be fined up to almost $152,000 for improper storage of hazardous materials, according to the U.S. Environmental Protection Agency.
Monson Cos. of Leominster, Mass., operates a warehouse, distribution, repackaging and chemical manufacturing facility at 1 Runway Road.
According to the EPA, Monson violated the U.S. Clean Air Act by not appropriately storing hazardous chemicals that can cause explosions or other violent reactions. The complaint alleges the facility stored incompatible chemicals close enough together that a spill or release of one chemical could result in a reaction with others, creating toxic gases, fire or an explosion.
The EPA alleges the plant violated requirements to: identify hazardous wastes so that they could be safely managed, maintain a proper emergency plan and submit a complete inventory of its hazardous materials to emergency responders.
Monson has since submitted the required hazardous chemical inventory form and has addressed the Clean Air Act hazards identified by the EPA inspector. The company has also completed hazardous waste determinations and properly removed some waste.
