United Refining permits new boiler at facility in Warren, Pa.

United Refining Co. has applied at the Pennsylvania Department of Environmental Protection for an air permit approval for installation of a 182.8 MMBtus/hr capacity natural gas & refinery gas-fired boiler at its facility in Warren in Warren County.

The DEP said in a notice in the May 2 Pennsylvania Bulletin that it intends to issue Plan Approval 62-017X to United Refining for the installation of this boiler. This will be designated as Boiler #6, and will be used to provide additional steam producing capacity to the existing refinery operations. Based on the information provided by the applicant and DEP’s own analysis, the subject source will result in potential emissions not to exceed 32.0 tons of carbon monoxide, 28.8 tons of nitrogen oxides (NOx), 8.0 tons of particulate matter, all of which will be particulate matter less than 2.5 microns (PM-2.5), 7.3 tons of sulfur oxides (SOx), 4.0 tons of volatile organic compounds (VOC), 0.62 ton of sulfuric acid, and 0.00036 ton of lead per year, calculated as a 12-month rolling total.

Proposed best available technology (BAT) for this installation will be the use of low-NOx burners with flue gas recirculation (FGR) for the control of NOx, use of low-sulfur fuels, including compliance with the TVOP H2S limits for refinery fuel gas for control of SOx, and good engineering and combustion practices. The Plan Approval will contain additional testing, monitoring, recordkeeping, and work practice requirements designed to keep the facility operating within all applicable air quality requirements.
