The Department of Environmental Quality seeks public comment on several proposed amendments to 252:100-9, Air Pollution Control. The amendments will resolve issues regarding emission standards for nitrogen oxides (NOx) from fuel-burning equipment. The changes would address emission standards for direct-fired fuel-burning equipment, fuel-burning equipment that uses more than one type of fuel, and equipment with technological limitations. The Department is also considering changes to address emissions from low-NO burners when these are operated at low heat input values. Other changes would bring the regulations in line with federal standards and incorporate the latest changes to federal regulations by reference. Written comments are due October 15, 2008. Oral comments may be made at the October 15, 2008, hearing and at the November 18, 2008, Environmental Quality Board meeting. http://www.oar.state.ok.us/register/Volume-26_Issue-01.htm#a16420.
