ITEM Application for Accreditation of an Exhaust Emission Control Device for Used Vehicles. INTRODUCTION This report is a staff evaluation of an exhaust emission control device for used vehicles as proposed by the Clean Air Car Project, an undergraduate project sponsored by the Environmental Quality Laboratory of the California Institute of Technology. The basis for evaluation and specific requirements are stated in the California Health and Safety Code, Sections 39107 and 39175 to 39184, and Title 13 of the California Administrative Code, Chapter 3, Subchapter 2, Articles 2 and 3. Test details and specific requirements are contained in the "California Exhaust and Fuel Evaporative Emission Standards and Test Procedures for Used Motor Vehicles under 6,001 Pounds Gross Vehicle Weight" as amended by the Board on March 18, 1970. ITEM Status Report on NOx Devices for 1966 through 1970 Models. Following adoption of test procedures and standards for oxides of nitrogen control devices for 1966 through 1970 model used vehicles the Board solicited applications for accreditation of potential devices. At this writing, none has been received. The legislation adopted last year was based on testimony that NOx control devices, e.g., vacuum advance disconnection, could be made available. The staff has informally been informed that some reluctance to submit devices has been based on concern for potential adverse effects on engine operation and wear due to vacuum advance disconnection. In order to clarify the issues the accompanying letter was sent to a number of auto manufacturers and other potential device suppliers. They have been invited to address the Board today to discuss their progress and problems. ITEM Staff Report on the Response of San Bernardino County Air Pollution Control District to Air Resources Board Resolution 71-116. The Air Resources Board at its meeting on December 15-16, 1971, considered the ARB staff report, "Survey of air Pollution from the Kaiser Steel Plant, Fontana, California," and pursuant to Section 39054 of the Health and Safety Code, adopted Resolution 71-116, directing that a copy of the report be sent to the San Bernardino County Air Pollution Control District, and requesting the District to submit a report within 90 days as to the action taken to control emissions from the Kaiser Steel Plant. In response to the resolution, the San Bernardino Air Pollution Control District submitted a report on March 8, 1972, with the following attachments: (1) a report from Kaiser Steel Corporation to the District entitled, "B.O.S.P. precipitator upgrading program-status report," and (2) a letter to the District from Kaiser, "Re: Open hearth precipitator upgrading program." ITEM Status Report on Air Pollution Problems in San Benito County. The air pollution problem in San Benito County concerns emission of cement dust from the Ideal Cement Plan in San Juan Bautista. The problem is illustrated in the two attached photos taken in late November 1969 of the plumes from the plant. The top photo which was taken shortly after sunrise shows that the plumes form the plant extended into Monterey County. ITEM Staff Report on the Proposed New Agricultural Burning Guidelines. INTRODUCTION In 1970, the Legislature added Chapter 10 "Burning", to Part 1 of Division 26 of the Health and Safety Code. Among the provisions in this Chapter, there is the requirement that the Air Resources Board established guidelines for regulation and control of agricultural burning in each of the state's 11 air basins. Local districts are required to develop implementation plans in accordance with these guidelines. Agricultural burning was defined as open fires used in the growing of crops and the raising of fowls and animals, in forest management and in range improvement. In 1971, the Legislature added to the definition open fires used in improvement of wildlife and game habitat. The Chapter specifies that guidelines for the Sacramento Valley, San Joaquin Valley, Bay Area, South Coast, North Central Coast and South Central Coast air Basins are to be established within six months. On March 17, 1971, the Air Resources Board adopted guidelines for regulating the burning of agricultural waste in the above six air basins. Implementation plans were developed by the districts with these air basins, and were approved by the Board. As required by law, the staff is in the process of developing new guidelines which will cover open burning in range improvement, forest management, improvement of land for wildlife and game habitat as well as open burning in farming operations. The new guidelines are to be applicable in all 11 air basins, to replace the old guidelines which are applicable to 6 air basins. ITEM People's Lobby Initiative (Proposition 9 - June Primary). At the March Meeting of the air Resources board, the Board announced that it would consider the arguments pro and con for the People's Lobby Initiative. The prior staff analysis, the Technical Advisory Committee's comments, and a copy of the Initiative itself are enclosed. ITEM Staff Report on Proposed Federal Regulations for Lead and Phosphorous in Gasoline. On February 23, 1972 the Administrator of the U.S. Environmental Protection Agency published proposed regulations on lead and phosphorous content in gasoline. A copy of the proposed regulations was not available, however, until after the Board meeting in March. The proposals differ slightly from the previously published version that was reported by the staff at the February 16, 1972 Board meeting. Comments on the proposed regulations are invited to be submitted within 90 days. In addition, EPA invites comments on the need for limiting the sulfur content of gasoline, or on alternative approaches which would achieve the same results as the proposed regulations. EPA has announced three public hearings on the proposals. One of the hearings will be held in Los Angeles on May 2, 1972. ITEM Staff Report on Air Monitoring Contracts. Under the provisions of Section 39067.1 of the Health and Safety Code, the Air Resources Board is directed to establish a program for obtaining data on air quality in each air basin, and the Board may contract with local or regional agencies for obtaining such data. ITEM Staff Report on Applications from Counties to Continue Open Burning on Waste Disposal Sites. INTRODUCTION As of the March 15, 1972 meeting, the Air Resources Board approved time extensions to use open fires for the purpose of disposal of solid waste for 295 city or county disposal sites. After the March Board meeting, the Board received a request from Trinity County for time extensions for two dump sites. There was also a request to extend three previously approved extensions in Madera County for another three months. The staff recommends approval for both requests.
