INFORMATIONAL ITEMS

Carol Coy, Deputy Executive Officer, Engineering and Compliance, presented this item. In December 2004 CARB adopted a new Air Toxics Control Measure (ATCM) to reduce toxic hexavalent chromium and nickel emissions from thermal spraying operations after a robust rulemaking technical study which included an industry survey. Cognizant of this rulemaking effort, AQMD staff identified over 30 possible thermal spraying operations in the South Coast Basin, and inspection visits to these facilities found a number of potentially high-emitting sources that will require control equipment upgrades. Since the ATCM establishes stringent emission capture and control requirements effective upon start up of new or modified operations by January 1, 2005, and at existing facilities by January 1, 2006, staff is immediately implementing the ATCM. All existing unpermitted thermal spraying operations (some previously exempt under Rule 219) must submit permit applications as soon as possible but not later than October 1, 2005. AQMD Compliance and Engineering staff are working with these sources to ensure required emission controls are expeditiously installed. Of particular note, the ATCM also includes a restriction on locating these facilities within 150 meters of the zoning boundary of a residential or mixed use area. Implementation of this ATCM in conjunction with Rules 1469 and Proposed Rule 1469.1 – Spray Operations Using Toxic Chemicals, will effectively require emission controls on all chromium application methods.
Susan Nakamura, Planning and Rules Manager, presented this item. Proposed Rule 1469.1 is a new rule that will regulate spraying operations that are using primers or coatings that contain hexavalent chromium. Operations using hand applications of chromate based primers or coatings, and thermal spraying operations are not regulated by the proposed rule. Proposed Rule 1469.1 establishes enclosure requirements, requirements for transfer efficiency, and housekeeping requirements. The core requirements under Proposed Rule 1469.1 are presented as three options. An owner or operator of a facility can select one of the following three options to demonstrate compliance: Option A: Annual Emission Limit; Option B: Installation of HEPA Filters or Better; or Option C: Facility-wide Risk Limit. Affected facilities must demonstrate compliance with either Option A, B, or C on or before July 1, 2007. Proposed Rule 1469.1 also includes an exemption for touch up and repair operations, and establishes requirements for monitoring, recordkeeping, and reporting. Bill Pearce from Boeing commented that he is working with AQMD staff regarding clarification of how an approved HRA could be used under Proposed Rule 1469.1. Proposed Rule 1469.1 is scheduled to be heard at the March 4, 2005 Governing Board meeting.
Rule 1402 – Control of Toxic Air Contaminants from Existing Sources
Susan Nakamura, Planning and Rules Manager, presented this item. Amendments to Rules 1401 are proposed to add and update risk values for the following toxic air contaminants: naphthalene, PCBs, PCDD, and PCDF. AQMD staff presented the results of an impact assessment from adding and revising the risk values for these toxic air contaminants. No impact is anticipated from implementation of the new risk value for naphthalene. Although the risk value for naphthalene has increased, the emission factor is so low that the overall change in the cancer risk is minimal. Regarding PCDD and PCDF, no impacts are anticipated as these toxic air contaminants are generally not used in the South Coast basin. There is one facility that is current using PCBs that may be affected under Rule 1402. Proposed amendments to Rules 1401 and 1402 are also recommended to revise the definition of "maximum individual cancer risk" to be consistent with the revised Risk Assessment Procedures. Proposed amendments to Rules 1401 and 1402 are scheduled for the March 4, 2005 Governing Board meeting.
Susan Nakamura, Planning and Rules Manager, presented this item. Amendments to Rule 1470 are proposed for consistency with the state ATCM. There are a series of minor modifications to clarify the current rule. The most substantive changes are to specify an effective date of January 1, 2006 for engines enrolled in a demand response program, and to prohibit non-emergency operation of emergency standby engines on school grounds during school sponsored activities. AQMD staff highlighted one key issue that was raised at the public workshop regarding the compliance date for facilities with four or more pre-1989 engines. The state ATCM extended the compliance date for these engines from January 1, 2006 to January 1, 2007. The AQMD staff is recommending that the January 1, 2006 date be maintained since the pre-1989 engines represent the dirtiest and oldest engines and affected facilities had a 20 month lead time since the adoption of Rule 1470 in April 2004. Proposed amendments to Rule 1470 are scheduled for the March 4, 2005 Governing Board meeting.
Marty Kay, Program Supervisor, Technology Advancement, reported that staff had worked with the BACT Scientific Review Committee to implement the CARB 2007 distributed generation (DG) emission standards. CARB will require, starting in 2007, unpermitted DG equipment (exempt from district permit) to meet emission limits equivalent to BACT for new large central generating stations. Staff was proposing the same BACT emission limits for all DG subject to an AQMD permit. The standards would assure that all DG equipment would be as clean as new large central generating stations. However, staff now recommends that this be accomplished by rulemaking rather than the BACT process.
Industry representatives said that engines need more time to meet CARB 2007 standards, and that other competing technologies are often not as good of a fit for a facility. Environmental group representatives were in favor of the proposal and pointed out that distributed generation is discretionary, so facilities should be limited to using clean electrical generating technologies
