EPA Final Rule on Emission Standards for Reciprocating Internal Combustion Engines

Posted in on Fri, Mar 1, 2013

The EPA is finalizing amendments to its national emission standards for hazardous air pollutants for stationary reciprocating internal combustion engines. The final amendments include alternative testing options for certain large spark ignition (generally natural gas-fueled) stationary reciprocating internal combustion engines, management practices for a subset of existing spark ignition stationary reciprocating internal combustion engines in sparsely populated areas and alternative monitoring and compliance options for the same engines in populated areas.  The EPA is establishing management practices for existing compression ignition engines on offshore vessels. It is also finalizing limits on the hours that stationary emergency engines may be used for emergency demand response and establishing fuel and reporting requirements for certain emergency engines used for emergency demand response.  The final rule is effective April 1, 2013.
