Essroc Cement Co. has agreed to pay a $1.7 million penalty and invest approximately $33 million in pollution control technology to resolve alleged violations of the Clean Air Act at six of its Portland cement manufacturing plants, according to the EPA.
The settlement will reduce more
than 7,000 tons of nitrogen oxides (NOX) and sulfur dioxide
(SO2) pollution each year. The Nazareth, Pa.-based
company also has agreed to spend $745,000 to mitigate the effects of past
excess emissions from its facilities.
“These comprehensive measures at
multiple Essroc facilities will achieve substantial reductions in harmful air
pollution,” said Ignacia S. Moreno, assistant attorney general for the
Environment and Natural Resources Division of the Department of Justice.
settlement, Essroc will install state-of-the-art pollution control technology
to control SO2and NOXat five of
its plants and demonstrate a selective catalytic reduction system (SCR) system
at two long wet kilns in its Logansport, Ind., plant. If successful, this will
be the first SCRs used on long wet kilns anywhere in the world. Essroc also will
permanently retire its sixth plant, located in Bessemer, Penn. This plant is
currently out of operation and its permanent retirement will ensure that the
facility does not restart without proper permitting under the CAA.
settlement also requires Essroc to spend $745,000 on a mitigation project to
replace old engines in several off-road vehicles at its plant sites. The
replacement engines are estimated to achieve approximately a 50 to 80 percent
reduction in nitrogen oxides in each engine.
pollution from cement plants - particularly sulfur dioxide and nitrogen oxides,
two key pollutants emitted from cement plants - is one of EPA’s National Enforcement
Initiatives for 2011 to 2013.
