Remarks from the Audience. ITEM Staff Discussion of Heavy-Duty Vehicle Evaporative Emissions Standard and Test Procedure. The proposed standard and test procedure incorporate the recommendations and decisions of the Air Resources Board's staff, the Technical Advisory Committee and the Board over the past several months. The standard is a departure from previous practice in that it states an objective based on an engineering evaluation rather than an explicit emissions test. It, therefore, represents a discretionary requirement of the Board beyond our emissions standard. This approach was chosen because of the complexity of prescribing a single test procedure applicable to all of the configurations and sizes in the heavy-duty vehicle class. Also, experience with the control systems on light-duty vehicles can be extended to the larger vehicles. A major issue in the development of the standard has been whether it should apply to all heavy-duty vehicles or only to those vehicles which are an extension of the manufacturers light-duty line. The development of control technology is more difficult for the heavier specialty vehicles. After meeting with industry representatives, the TAC recommended that all heavy-duty vehicles be included. The procedure covers all vehicles but provides for a possible one year extension of the effective date upon a showing of technological necessity. An extension may be granted only by Board action and is limited to those vehicles which are not an extension of the light-duty line. This follows the policy by the Board at its meeting on April 19, 1971. The regulations become applicable to those heavy-duty vehicles with engines manufactured after January 1, 1973. This corresponds to the effective date of the exhaust standards for the heavy-duty vehicles which were adopted last November. ITEM Staff Report on Petition for Air Basin Boundary Change in Siskiyou County. The Siskiyou County Board of Supervisors, in a resolution dated March 10, 1971, requested that all of Siskiyou County be placed in one air basin, the Northeast Plateau Air Basin. At the may 19, 1971 Board meeting, Supervisor Earl Ager of Siskiyou County asked that the County's request be considered early enough to enable the County to adopt a budget for the next fiscal year. The staff finds no technical objections to the County's proposal and therefore recommends the emergency adoption of Resolution 71-38 with confirmation to be made in a public hearing at the July Board meeting. ITEM Staff Report on Mandatory Inspection Study. Section 39067.2 of the Health and Safety Code (AB 78, 1970) directed the Air Resources Board to undertake a study to determine: 1. The reduction in automotive emissions that could be achieved by practicable vehicle emission inspection programs; and 2. the costs of carrying out such programs on a permanent basis, and to report its findings and recommendations to the legislature no later than July 1, 1971. Sixty-five thousand dollars was provided in AB 78 (1970) for conducting the study. In response to the legislative directive, a request for proposals on such a study was sent to prospective contractors early in July, 1970. Because the law required that the study include a determination of effects of practical inspection programs, an additional part had to be included to test inspection methods which may be potentially practical for a statewide program. The fund provided by the legislature was not sufficient for this additional part. Additional financial support, amounting to approximately $336,000 was provided by the State Highway Commission. A contract for a two-part study was let to Northrop Corporation on November 30, 1970. ITEM Staff Report on Approval Policy for Granting Time Extensions to Cities and Counties for Open Burning Dumps. At its May 19, 1971 meeting, the Board adopted a policy for allowing time extensions to cities and counties to continue to use open fires for the purpose of disposal of solid waste. The policy requires each city council or county board of supervisors to apply before November 1, 1971 for permission to continue to burn in the open on their solid waste dumps. Information must also be provided on location of dumps, population density, number of people served, amounts of waste disposed handled, unavailability of other disposal methods and a plan and timetable to phase out each open burning dump. A policy for approval was also considered at that meeting, but it was referred to the staff for further study. The Board wanted to be sure that any approval policy adopted would not be in conflict with policies of other State agencies having an interest in solid waste disposal. ITEM Petition of the Environmental Defense Fund and Regulation of Lead in Gasoline. Attached is a letter dated May 11, 1971 from Mr. Wigert, the attorney for the Environmental Defense Fund (EDF). It quotes the following sentence from the Attorney General's letter of March 8, 1971: "The county air pollution control districts are clearly authorized to adopt regulations governing the specifications of fuel used within the districts." Mr. Wigert then demands that the ARB set an exhaust emission standard for lead. His theory seems to be that in doing so the counties will be forced thereby to adopt regulations controlling lead in gasoline.
