EPA published in the Federal Register (79 FR 48072) a notice announcing its decision to not make any regulatory changes based on its reconsideration of the final National Emission Standards for Hazardous Air Pollutants (NESHAP) and New Source Performance Standards (NSPS) for Reciprocating Internal Combustion Engines (RICE). These rules are sometimes referred to as the “RICE NESHAP” and the “Engine NSPS.”
The three issues reconsidered by EPA include:
• the timing for compliance with the ultra-low sulfur diesel fuel requirement for emergency compression-ignition stationary engines that operate for emergency-demand response, voltage/frequency deviations or local reliability;
• the timing of and information required for the reporting requirement for emergency stationary engines that operate for emergency demand response, voltage/frequency deviations or local reliability; and
• the conditions for operation of an engine for up to 50 hours annually in non‐emergency situations as part of a financial arrangement with another entity.
In the Federal Register notice, EPA provides instructions for petitions for review of EPA’s decision, as follows, “Any petitions for review of the letters announcing the EPA’s decision not to propose changes to the regulations in response to the public comments received on the three issues under reconsideration described in this Notice must be filed in the U.S. Court of Appeals for the District of Columbia Circuit by October 14, 2014.”
