Executive Officer
Background
AQMD's New Source Review (NSR) regulations require applicants to use Best Available Control Technology (BACT) for new sources, relocated sources, and for modifications that increase emissions. Regulation XIII – New Source Review also requires the Executive Officer to periodically publish BACT Guidelines for commonly permitted equipment. On December 11, 1998, the Governing Board approved a new format, process, and procedures for updating the AQMD’s BACT Guidelines. The Board also directed staff to report back on progress made, on a quarterly basis. On October 20, 2000, the Governing Board approved an amendment to the NSR regulations to bifurcate the BACT requirements into federal LAER/BACT for major polluting facilities and minor source BACT (MSBACT) for non-major polluting facilities. As a result of this amendment, Part B of the BACT Guidelines now assists staff and the public to determine LAER/BACT for only major polluting facilities.
New Listings Part B - LAER/BACT Determinations for Major Polluting Facilities of the BACT Guidelines
Following are eleven (11) new BACT determinations listed under Section 1, Part B of the BACT Guidelines. This work has been in coordination with the BACT Scientific Review Committee (SRC). The SRC is a technical group whose membership includes industry, environmental groups, CARB, and U.S. EPA. The purpose of the new listings is to provide information to permit applicants and permitting staff regarding recent LAER/BACT determinations for major polluting facilities.
Boilers
Three new listings are for natural gas firetube boilers (Application Numbers 364504, 366569, and 366879) with ratings of 16.3, 21 and 7.5 mmbtu/hour respectively. The NOx limit for the 7.5 and 16.3 mmbtu/hour is 12 ppmvd @ 3% O2, and the NOx limit for the 21 mmbtu/hr is 7 ppmvd @ 3% O2. Ultra-low-NOx burners will be used to achieve 12 ppmv limit and SCR will be used to achieve 7 ppmv limit.
CO2 Plant
One new listing is for a CO2 recovery plant (Application Number 371781) that treats a CO2 rich effluent from a hydrogen plant of a nearby refinery. BACT for this plant is a regenerative thermal oxidizer (RTO) to control non-methane, non-ethane hydrocarbon (NMNEHC) emissions. The RTO control device will be required to reduce NMNEHC emissions by at least 95% or 25 ppmv measured as carbon; and CO to no more than 10 ppmv. This BACT determination is under public review.
Dry Cleaning Machine
One new listing is for a petroleum solvent dry cleaning machine (Application Number 364307). Operator will be using Exxon 2000 cleaning solvent at an anticipated usage rate of 20 gallons/month. BACT requirement for this machine is the use of a dry-to-dry, closed loop system with a refrigerated vapor condenser.
Flexographic Printing
Two new listings for flexographic printing:
— A non-heatset flexographic press (Application Number 353387) that prints labels on various substrates. BACT requirements are met by using 1) UV inks, and 2) cleanup solutions containing no VOC.
— A flexographic press and oven (Application Number 321072) that is used to print on plastic bags for a variety of end uses. BACT requirements are met by installing and operating 1) a permanent total enclosure meeting requirements specified by U.S. EPA, and 2) a regenerative thermal oxidizer at 95% overall control efficiency.
Internal Combustion Engine
One new listing is for a 110 H.P. emergency internal combustion engine (Application Number 372882) that drives a standby fire pump. BACT emissions limits for this engine are NOx at 6.9 grams/bhp-hr, PM at 0.40 grams/bhp-hr, and VOC at 1 grams/bhp-hr. The engine achieves these limits by using two catalysts in series: 1) a reducing catalyst which selectively reduces NOx to N2, and 2) an oxidation catalyst which reduces CO, ROG and PM.
Letterpress Printing
One new listing is for a letterpress printing (Application Number 287260) that is designed to use UV inks exclusively in printing labels.
Lithographic Printing, Non-Heatset
Two new listings for non-heatset lithographic printing:
— An offset lithographic printer that is used to print container lids (Application Number 357056). This press has six printing units and one curing system. This facility operates several lid and pail printers that use UV inks, and wash solutions in compliance with Rule 1171.
— A printing press that is used to print inserts and brochures (Application Number 367452). BACT requirements are met by using UV inks, fountain solution < 8% by volume VOC, and blanket and roller washes with vapor pressure of VOC £ 3 mmHg @ 20 degrees Centigrade.
Recommendation - Semi-annual Reporting
Staff recommends that the reporting frequency of this BACT Guidelines be changed report from a quarterly to a semi-annual basis. This will allow for a more comprehensive listing of new updates to Part B, and the development of proposed revisions to Parts C and D for Minor Source BACT, if required.
Conclusion
Staff sincerely extends its appreciation to SRC members and others who assisted in updating the BACT Guidelines. In particular, the commitment of past and present continuing SRC members in the development and review of the attached information is much appreciated.
