ITEM NO.: 73-20-2 Public Hearing to Consider the Adoption of a State Air Pollution Emergency Contingency Plan. RECOMMENDATION The Board approve Resolution No. 73-49, thereby adopting the attached Air Pollution Emergency Contingency Plan. DISCUSSION The revised proposed Air Pollution Emergency Contingency Plan has been developed pursuant to the Office of Emergency Service's Administrative Order 72-3, and as required by the federal regulations for the Preparation, Adoption and Submittal of the Implementation Plan for Achieving and Maintaining the National Ambient Air Quality Standards, Section 51.16, Part 51, CFR. A public hearing is being held, for consideration of the proposed Air Pollution Emergency Contingency Plan; notice of public hearing was published on August 16, 1973. Attached is a copy of the proposed plan and a staff report which summarizes the salient features of the proposed plan. Also attached are copies of letters received prior to September 12, 1973 from local districts and State Health Department commenting on the proposed plan. ITEM NO.: 73-20-3 Public Hearing - Proposed Amendments to Regulations in the California Administrative Code on Air Pollution Records. RECOMMENDATION Approve Resolution 73-50, thereby amending the Air Pollution Records regulations as proposed in the attached. DISCUSSION These proposed amendments, if adopted, would bring the Administrative Code into conformity with Section 6254.7 of the Government Code, as amended on July 9, 1973. This legislation excludes air pollution emission data from the provisions of state law that except trade secrets from public records, but provides that other information used to calculate emission data are not so excluded. ITEM NO.: 73-20-4 Requests for the Extension of Open Burning at Disposal Sites. RECOMMENDATION Deny Kern County's appeal. Grant Kings County additional time extensions for the Lemoore, Stratford, and Corcoran dump sites (Resolution 73-48). BACKGROUND 1. MR. L. Dale Mills, Director of Public Works and County Surveyor requested time at the September Board meeting to appeal the Board's denial of Kern County's request for additional time extension at two dump sites. The County has not presented any new information which might affect the staff's earlier recommendation. 2. Kings County Board of Supervisors request an additional three month for the Stratford, Lemoore and Corcoran dump sites. The Staff investigated and determined that the County will require additional time to phase out burning of these sites. ITEM NO.: 73-20-5 A final report on an Emission Inventory at Kaiser Steel. RECOMMENDATION This report is in response to the Board's instructions given at the Board meeting on April 4, 1973 in Riverside. SUMMARY As instructed by the Board, the staff, in coorperation with San Bernardino County air Pollution Control District and Kaiser Steel, developed two reports (an interim report and a final report) on emissions from Kaiser Steel. The reports include a comparison of the Kaiser Steel emissions with the total emission inventory for San Bernardino County. An interim report was presented to the Board at its meeting on June 21, 1973. The final report is being presented to the Board today. This final report contains more information based on actual source tests and less based on published emission factors and engineering estimates than the interim report. In comparison with the interim report, this final report shows reductions in emissions of particulate matter, sulfur dioxide and oxides of nitrogen and an increase in emissions of carbon monoxide. A copy of this report is attached. ITEM NO.: 73-20-6 Discussion of Complex Source Regulations. RECOMMENDATION Board direct the staff to prepare by mid-October 1973, a Proposed Revision to the State Implementation Plan to Provide for the Review of Complex Sources. DISCUSSION EPA regulations require the states to submit implementation plan revisions to provide for reviewing and for preventing the construction of complex sources that would prevent the attainment or maintenance of any national ambient air quality standards. This staff report summarizes EPA's requirements and related ARB actions to date, and recommends action the Board may take in response to the EPA regulations. ITEM NO.: 73-20-7 Status of EPA Enforcement Activities. RECOMMENDATION This is an informational report. SUMMARY The EPA has taken direct enforcement action in California. Nine notices of violation have been issued and EPA has written numerous letters to emission sources requesting production and emission information. The EPA enforcement activities are in three categories: Category 1: The area where the State is given the primary responsibility for enforcement, i.e., existing regulations and emission limitations for stationary sources as contained in the State Implementation Plan, including Compliance Schedules; Category 2: The area where EPA has promulgated regulations in lieu of state action, i.e., Compliance Schedules - Future Rules and Permit System Administration; Category 3: The area where EPA has primary responsibility but has indicated a willingness to delegate enforcement to the State, i.e., New Source Performance Standards and National Emission Standards for Hazardous Air Pollutants. ITEM NO.: 73-20-8 Asbestos Standards and Control Regulations. RECOMMENDATION A committee of the Board review the alternatives available for controlling asbestos. DISCUSSION On May 2, 1973 the Board directed the staff to review jointly, with the State Health Department, the situation regarding asbestos standards and controls and to advise the Board on a course of action. Since May 2, the staff has met with representatives of the Department of Health to examine the available information and to consider the feasibility of setting an asbestos air quality standard. The Department has concluded that it may be feasible to adopt an "interim semi-quantitative standard." However, there are a number of issues which are difficult to resolve. These issues include: a. None of the existing methods for measuring asbestos levels in ambient air are adequate for use as a reference method. (The status of analytical methods is described in the attached August 15 memorandum from the Department.) b. There is a lack of data on the relationship between asbestos levels in the ambient air and health effects. (Health damage from occupational exposure is described in the attached June 25 letter from the Department.) c. The choice of ways to proceed is complicated by the existence of EPA regulations for the control of asbestos from some sources. In view of these issues the staff recommends that a committee of the Board be formed to examine the alternatives for asbestos control.
