The NAM is part of the SSM Coalition, named for EPA's new Clean Air Act regulations governing special circumstances often present during startup, shutdown or malfunction (SSM) of process equipment or pollution control equipment. On Jan. 4, 2011, the Coalition moved to file an amicus brief in litigation brought by the Portland Cement Association which challenges 2 EPA regulations governing Portland Cement plants. Our particular interest is the rule which establishes national emission standards for hazardous air pollutants (NESHAPs) under Section 112 of the Act.
EPA's new approach to establishing NESHAPs and its novel interpretations of Section 112 apply not only to the portland cement case, but it plans to adopt similar requirements for a variety of other sectors, including chemical plants, pulp and paper mills, steel pickling operations and wood furniture manufacturing.
The court granted permission to file an amicus brief, and we did so on May 23, 2011. The brief argued that EPA's MACT standard cannot be met by any existing facility and that EPA's standard does not satisfy the statutory requirement that it be achievable.
We also argued that EPA did not justify its decision to no longer recognize the special circumstances that arise during equipment malfunctions. Reasonable performance standards should recognize that sudden, unexpected failures of a manufacturing process or pollution control technology are not part of a source's normal operating mode, and should not be subject to harsh EPA penalties when they occur. EPA could have considered alternatives, such as work practice standards, that would address deviations from normally achievable emissions standards that may occur during periods of malfunction.
Finally, we argued that EPA should have recognized that differences in the source of raw materials makes compliance with a uniform national MACT standard difficult or impossible. It was arbitrary and capricious for EPA fail to make allowances for emissions based on the sources of supply.
On Dec. 9, 2011, the court remanded the NESHAP rule to EPA for reconsideration, but rejected all other issues that challenged EPA's actions.
