ITEM NO.: 90-2-1 Public Hearing to Consider Adoption of Amendments to Regulations Regarding the Procedures for Exemption of Add-on and Modified Parts from the prohibitions of Sections 27156 and 38391 of the California Vehicle Code. RECOMMENDATION The staff recommends that the Board adopt the proposed revisions to the current "Criteria for the Evaluation of Add-on and Modified Parts." The proposed revisions would allow the ARB to focus limited ARB staff and testing resources on aftermarket parts which are most likely to cause increases in emissions. This would permit the staff to examine more parts which may impact emissions, and would result in the most cost-effective use of state resources. DISCUSSION ARB staff and members of the aftermarket parts industry have worked together to develop revised regulations which streamline the exemption process for part manufacturers while not compromising air quality. The proposed revisions fall into two broad categories. The first category of parts is described as "General Criteria" parts for which vehicle or engine emission testing may still be required. The testing requirements have been streamlined in terms of test procedures, and numbers and types of test vehicles. The second category of parts is "Compliance Criteria" parts. These are parts for which written criteria for exemption have been developed, and require no emission testing. In addition, new heavy-duty testing procedures are proposed in these revisions. SUMMARY OF IMPACTS There are potential cost savings to aftermarket part manufacturers seeking exemptions from the prohibitions of VC 27156 and VC 38391 under the revised regulations. Manufacturers employing Compliance Criteria would have their costs reduced to a minimum. General Criteria part manufacturers would realize a cost benefit as a result of fewer test vehicles, and lower cost emission tests. The staff has determined that there would be a small, unquantifiable emission benefit from the adoption of the proposed revisions. ITEM NO.: 90-2-2 Guidance related to the Transportation Requirements of the California Clean Air Act. RECOMMENDATION That the Board adopt Resolution #90-11 in support of the approach and policies presented in this guidance document. DISCUSSION This document provides guidance on implementing the transportation provisions in the California Clean Air Act for air pollution control districts, as well as transportation agencies. The guidance outlines the various requirements and recommends how the districts and transportation agencies can address the requirements in their development of the 1991 air quality plans. In addition to addressing the specific requirements of the Act, the guidance suggests a framework for integrating transportation and air quality planning so that the two efforts are mutually supportive. Transportation Control measures (TCMs) are required to the extent that they are needed for an area to attain the state air quality standards as soon as practicable. transportation provisions in the Act are dependent upon area classification. They address control measure development and set transportation performance standards. In general, nearly all of California's urban areas will be expected to adopt reasonably available transportation control measures, make provision to develop indirect source control programs, and provide for public education programs in support of reducing emissions from transportation and areawide sources. Areas with serious air quality problems will need to adopt TCMs to substantially reduce passenger vehicle trips and miles traveled per trip. Severe areas will need to achieve an average weekday commute of 1.5 or more persons per vehicle by 1999 and no net increase in vehicle emissions after 1997. The guidance document also includes discussion of monitoring and reporting mechanism. The guidance includes a suggested list of reasonably available transportation control measures. The list includes: Regulatory Measures 1) Employer based trip reduction rules 2) Trip reduction rules for other sources 3) Management of parking supply and pricing Transportation System Improvements 1) High occupancy vehicle system plans and implementation programs 2) Comprehensive transit improvement programs for bus and rail 3) Development policies to strengthen transit access and reduce auto trips for new and existing land developments The guidance document has been discussed at meetings of the CAPCOA Planners and the Transportation Air Quality Review Group and was presented at a public workshop held on December 6, 1989. In addition, staff has consulted with Caltrans on an ongoing basis in the development of the report. Since the workshop, staff has received considerable written comments through letters from local air districts, transportation agencies, etc. In general, the comments have been supportive of the approach taken with suggestions for strengthening or clarifying specific portions of the text. These suggestions have been addressed in the final draft document. Staff anticipates wide distribution of the final document to air districts, state, regional and local transportation agencies, transit districts, cities, and counties. ITEM NO.: 90-2-3 Public Meeting to consider a Proposed Update to List of Substances: Toxic Air Contaminant Program. RECOMMENDATION The staff recommends that the Board approve the revisions to the Toxic Air Contaminant Identification List as proposed in the staff report. DISCUSSION This report presents the latest update to the list of substances in the Board's Toxic Air Contaminant Program. This list contains substances identified as toxic air contaminants by the Board and those which are candidate toxic air contaminants. The list is prepared and used by the staff in setting priorities for evaluating substances as toxic air contaminants. The first list was approved by the Board in January 1984 and has been updated each year thereafter. The proposed Toxic Air Contaminant Identification List - January 1990, reflects changes to last year's list. The proposed changes were developed after reviewing updated information on substance health effects, usage, emissions, and exposure. In consultation with DHS staff we reviewed health effects information from the International Agency for Research on Cancer, the U.S. Environmental Protection Agency and the National Toxicology Program. Emissions information from the Superfund Amendments and Reauthorization Act, Title III, Section 313, 1988 Toxic Chemical Release Inventory and toxics inventories from selected local air pollution control districts were also reviewed. Along with this emissions information, the staff reviewed the 1986 Toxic Substances Control Act Inventory List citing production volumes for listed substances within California. Staff also conducted modeling and a review of health effects, exposure, usage, and atmospheric chemistry information and discussed relevant issues with the staff of the Department of Health Services. A request for information on substances included on the proposed January 1990 list and the substances under consideration for addition to the list was mailed to the public in September 1989, as part of Board staff review of available information regarding substances. The Scientific Review Panel on Toxic Air Contaminants was notified of the proposed changes to the list. SUMMARY AND IMPACTS OF PROPOSED ACTION The following changes are proposed to the list in 1990: (1) move methylene chloride from Category II-A to Category I as a result of its July 1989 adoption by the Board as a toxic air contaminant; (2) move from Category II-B to Category II-A acetaldehyde, benzo(a)pyrene and diesel exhaust because they have entered the air toxic contaminant identification review proess; (3) remove the footnote on PAHs because benzo(a)pyrene and diesel exhaust are now under review; and (4) add acrylamide, 1,1-dimethylhydrazine and hydrazine to Category II-B of the list due to the potential for exposure in California and the potential carcinogenicity of these compounds.
