AGA Comments on EPA Proposal to Amend NESHAPS for Reciprocating Internal Combustion Engines (Aug. 9, 2012)
On August 9, AGA filed a comment letter with EPA supporting implementation of recent INGAA-EPA settlement agreements through an EPA rulemaking, particularly the revision of NESHAP rules for reciprocating internal combustion engines ( RICE ) located at area sources. See National Emission Standards for Hazardous Air Pollutants for Reciprocating Internal Combustion Engines; New Source Performance Standards for Stationary Internal Combustion Engines, EPA-HQ-OAR-2008-0708 (NOPR issued June 7, 2012).
AGA s comments stated that EPA s proposed revisions will be more workable for our members RICE at area sources, particularly at remote locations. We also indicated support for comments filed by Laclede Gas Company requesting relief under the limited use engine exemption and additional relief for emergency engines at area source natural gas storage fields associated with natural gas distribution, and for area source engines where there are 5 or fewer offsite residential buildings within a 0.25 mile radius. AGA also asked EPA to generally allow a limited use RICE exemption for area sources similar to that allowed for major sources under the current rules, and to exclude limited use RICE (those that operate less than 100 hours per year) from emissions and operations limits entirely, whether located at major or area sources.
