SERVICES AND LABORATORY UNIT
PROPOSED PART 70 AIR OPERATING PERMIT RENEWAL/MODIFICATION
The LDEQ, Office of Environmental Services, is accepting written comments on he proposed Part 70 air operating permit renewal/modification for Lion Copolymer Geismar, LLC, 6191 Highway 30, Geismar, Louisiana 70734 for the Services and Laboratory Unit. The facility is located at 36191 Highway 30, at the intersection of Highway 30 and Highway 73, Geismar, Ascension Parish.
Lion Copolymer Geismar, LLC (Lion Copolymer) requested a renewal and modification of the Part 70 Air Operating Permit for the Services and Laboratory Unit.
Activities associated with the Services and Laboratory Unit consist of upkeep and repair of process equipment and plant grounds. Sources of air emissions include sandblasting, painting, emergency generator and fire pump engines exhaust, fuel storage tanks, oil storage tanks, parts cleaning stations, and other miscellaneous activities in support of the production units at the Facility. The support laboratory is used for routine quality control/environmental analysis, as well as research and development testing that occurs in the lab and the pilot plant. Sources of air emissions from the laboratory include solvent and chemical evaporation associated with conducting routine testing and experiments that are released through the laboratory ventilation hoods. The pilot plant consists of various process equipments that are a source of emissions when the plant is utilized. In addition to renewing the permit, Lion Copolymer is proposing to:
· Permit the EPDM Pilot Plant and Lab Reactors that were previously approved Case by Case Insignificant Activities as emission sources;
· Delete Diesel Driven Air Compressor for Sand Blasting (EPN 2902) as an emission source since portable, non-road engines are now used on an as needed basis, which are now exempted from requirement to obtain a permit;
· Update Insignificant Activities;
· Reconcile emission rate estimates based on current facility operations and process knowledge; and
· Include PM2.5 emission rates.
Estimated emissions in tons per year are as follows:
