CHICAGO (Sept. 27, 2005) — U.S. Environmental Protection Agency Region 5 has cited CertainTeed Corp. for alleged clean-air violations at the company's roofing materials manufacturing plant at 3303 E. Fourth St., Shakopee, Minn.
EPA alleges that CertainTeed failed to include two of its manufacturing processes in its state operating permit application and has been operating those processes without a permit. EPA also alleges that two other processes have been operated without the emission control efficiencies required in its state operating permit.
"EPA's mission is to protect public health and the environment," said Regional Administrator Thomas V. Skinner. "We will take whatever steps are needed to ensure compliance with the Clean Air Act."
These are preliminary findings of violations. To resolve them, EPA may issue a compliance order, assess an administrative penalty or bring suit against the company. CertainTeed has 30 days from receipt of the notice to meet with EPA to discuss resolving the allegations. |
