PORTLAND — A Portland asphalt company has agreed to pay $68,400 in penalties for failing to comply with federal regulations designed to prevent oil spills from reaching waterways.?According to the U.S. Environmental Protection Agency (EPA), Triram Connecticut, LLC illegally discharged approximately 1,000 gallons of oil from its facility into the Connecticut River in January 2009. The oil spill occurred when piping connecting a 13,000 gallon oil tank to a boiler failed and released 8,000 gallons of oil into the facility’s secondary containment area. The spill prompted an emergency response from the local fire department and the state’s Department of Environmental Protection. Triram also hired an oil spill response company to contain the spilled oil and spent more than $500,000 on the cleanup.
