INFORMATIONAL ITEMS
- Rule 219 – Equipment Not Requiring a Written Permit Pursuant to Reg. II
Lee Lockie, Director of Area Sources presented this item. The primary purpose of amending Rule 219 this year is to exempt certain small emission sources from written permits and to further clarify or revise existing exemptions. The proposed amendments exempt closed loop solvent recovery systems with refrigerated or water-cooled condensers, foam application equipment using two component polyurethane foam where no VOC, chlorofluorocarbon, or methylene chloride blowing agent is used, toner refilling and recycling equipment, and organic solvent storage tanks that have no VOC emissions. The amendments also substitute a VOC limit for the vapor pressure exemption for lubricants, clarify fee obligations for previously exempt equipment, and provide for a one gallon per day exemption per facility for organic solvent usage in food and pharmaceutical processing equipment. Finally, staff is reorganizing the rule and adding an index to make it easier to locate and understand the exemptions. - Rule 1136 – Wood Products Coatings Technical Assessment
Larry Bowen, Planning and Rules Manager presented this item. Rule 1136 reduces emissions of VOC from the coating of wood products. It was last amended in June of 1996 to establish interim limits and delayed the implementation of the final limits for up to seven years to allow for the development and implementation of the low-VOC technologies. In addition the rule requires wood finishers to report their progress in using products that will meet the final limits by January of 2003. - Rule 1162 – Polyester Resin Operations
Larry Bowen, Planning and Rules Manager presented this item. Rule 1162 was amended in November of 2001. Included in those amendments was a requirement for the use of non-atomizing spray application techniques. There was concern expressed by industry about the technology for the application of gel coats. A future effective date of July 1, 2003 was set in the rule and staff was to assess the availability of the technology prior to that implementation date. Earlier this year staff brought assessment results to the committee that indicated the technology had been achieved. However, the criteria for defining the spray application technique, three inches of coherent spray, does not work for the gel coat application. Another parameter, such as pressure could be required to define non-atomizing spray application technique for gel coats. Staff is working on this through a testing program in cooperation with the industry. Additional time is needed to complete this work and therefore staff is recommending the July 2003 compliance date for the non-atomizing spray application of gel coats be extended to July 2004 to allow this to happen. A subsequent amendment to the rule will be recommended in about six months to modify the definition and staff will report back to the committee before that rule amendment. - Status Report on 2003 AQMP
The Committee deferred this item since they were given a presentation on the proposed modifications to the 2003 AQMP as part of the Mobile Source Committee meeting - Modify Existing Incentive Program to Assist Dry Cleaners Converting to Non-Perchloroethylene Alternative Cleaning Technologies
Pom Pom Ganguli, Public Advisor presented this item that will be going to the Board for approval on July 11, 2003. Staff recommends some adjustments to the financial incentives program to assist dry cleaners to convert to non-perc alternative technologies. This action will: (1) increase the grant for CO2 technologies from $10,000 to $20,000 each to defray the higher cost of this technology; (2) suspend the grant for silicon-based solvent technologies effective April 4, 2003 due to toxicity concerns; and (3) provide partial grants of up to $5000 for special situations involving wet cleaners. - Proposed Airborne Toxic Control Measures to Reduce Diesel Particulate Matter Emissions for In-Use and New Stationary Diesel-Fueled Engines
Marty Kay, Program Supervisor, Science and Technology Advancement presented this item. CARB has conducted several workshops for a proposed Air Toxic Control Measure for new and existing stationary diesel engines. They expect to bring it to their Board for adoption in October and then local Districts will have 120 days to adopt it or an equivalent rule, or enforce the CARB ATCM.
The key public comments focused on de minimus values for certain exemptions. Staff is establishing de minimus values for food and pharmaceutical equipment and has agreed to further evaluate de minimus values for storage tanks using small concentrations of hydrofluoric and hydrochloric acid solutions and cleaning operations for UV/EB printing facilities.
A number of wood finishers submitted the progress reports. In addition the staff notified the known wood finishers of the requirement in November and again in March for those that did not respond to the November notice. A survey form that would meet the requirements of the progress report was included with each notice. In addition staff has been conducting site visits to observe the coating operations at a number of facilities.
As a result of the survey and site visits staff has found that there are multiple low-VOC compliant technologies being used and that there are adequately performing compliant finishes available and being used throughout the wood coating industry across the vast spectrum of products. There are however some specific applications that despite progress require additional work. An example is a manufacturer of high quality guitars where a product has not yet been found that meets their standards.
Staff believes the survey represents the cross section of the industry. Slightly less than half of the universe of sources responded. Of those that responded 16% fully comply with the July 2005 limits, about 1/3 comply with some of their coatings but not all, a little over ½ have not yet met the limits and 1% have elected to use add-on controls in lieu of the low-VOC technology.
It is recommended that the rule limits and July 2005 compliance date remain in effect. Staff will continue to work with the coating suppliers and end users on the rule implementation and will report back to this committee on the progress. Committee members expressed concern regarding the impact of air quality regulations on this and other industries and wanted staff to analyze the impact of rule implementation. Committee Chair Loveridge requested that Economist Jack Kaiser be invited to the next Board Retreat to discuss the impact of air regulations on L.A. businesses. Elaine Chang, Deputy Executive Officer, Planning and Rules, committed to further address economic issues and concerns. It was agreed that District staff will take another look at the Socio-Econ analysis and present an update information for consideration at the next Board Retreat.
The focus of the proposed ATCM is the reduction of diesel particulate.
For diesels under 50HP, it will only require new diesels to meet current EPA non-road emission standards.
For prime stationary diesels over 50 HP, new engines starting in 2005 will be limited to 0.01 g/bhp-hr of PM. Existing engines will by 2009 have to meet the same limit or reduce PM by at least 85%.
New emergency engines will by 2005 be limited to 0.15 g/bhp-hr, 100 hours/yr of non-emergency use and no interruptible electric contracts. However, if the engine is <0.01 g/bhphr, it will be allowed 200 hours of non-emergency use. Emergency use will not be limited.
Existing emergency diesels will be limited in their non-emergency use, depending on the PM emissions. The limits will range from 18 hours/year for <0.4 g/bhp-hr to 200 hours/year for <0.01 g/bhp-hr. These limits will take effect in a phased manner from 2006 to 2009. Facilities with existing interruptible electric contracts may use existing diesels for this if PM < 0.15 g/bhp-hr.
Although existing stationary agricultural diesels won’t be regulated, for the first time new stationary ag engines will be limited to 0.15 g/bhp-hr and be required to use CARB diesel fuel.
Emergency diesels will be prohibited from non-emergency use within 1000 feet of a school if children are present, and diesels over 50 HP will be required to use CARB diesel fuel.
