The settlement addresses storm water discharge and storage of oil
The U.S. EPA announced a settlement with J.G. MacLellan Concrete Co., that resolves alleged violations of the Clean Water Act. MacLellan, which manufactures ready-mix concrete in Lowell, Mass., and Milford, N.H., has agreed to make environmental improvements at its Lowell plant worth $94,500 to settle claims that it violated federal clean water laws at both facilities. MacLellan also agreed to pay a penalty of $50,000 for its failure to fully comply with various Clean Water Act regulations related to its discharge of storm water and storage of oil.
The settlement is the latest in a series of enforcement actions taken by EPA New England to address storm water violations from industrial facilities and construction sites around New England.
Under the terms of the settlement, MacLellan Concrete Co., will remove a storm drain from a public road in front of the Lowell plant and re-grade the plant's entrances, which together will reduce pollution from storm water discharges at the Lowell site. The Lowell facility discharges water into the Merrimack River, and the Milford facility discharges into the Skowhegan River.
The case stems from a Jan. 2017 inspection in Lowell and a Nov. 2016 inspection in Milford. Following these inspections, EPA's New England office charged the company with failure to follow the requirements in its permits for discharging storm water, unauthorized discharge of water used in washing down its concrete trucks at the Lowell facility, and failure to comply with the Clean Water Act's Spill Prevention, Control and Countermeasure regulations.
Process wastewater discharges are prohibited under the Clean Water Act unless a company obtains a permit allowing those discharges. Wastewater from concrete plants typically contains high pH, oils, greases and high levels of solids. When these solids settle they can form sediment deposits that destroy plant life and spawning grounds of fish. Alkaline waters that wash-off trucks and from concrete manufacturing sites are highly corrosive. Rather than get individual discharge permits with strict waste limits, most concrete manufacturing facilities treat, and often recycle, their process wastewaters onsite.
