ITEM NO.: 75-16-2 Report on Proposed Permit System Rules that Consider Ambient Air Quality. RECOMMENDATION Informational Report. SUMMARY A task force consisting of EPA and ARB personnel has been working on improving existing rules for implementation of new source review requirements. This report on the proposed new rules is being presented to the Board for discussion and comment. Several air pollution control districts and EPA, Region IX, have been invited to participate in this discussion. ATTACHMENTS: Discussion of Proposed Rules. Proposed Rules A and B plus associated definitions. ITEM NO.: 75-16-3 Proposed Amendments to Regulations Limiting the Sulfur Content of Unleaded Gasoline. RECOMMENDATION 1. That the Board not adopt an accelerated schedule of limits of sulfur content of unleaded gasoline unless air monitoring data or additional medical evidence indicates the need. 2. That the Board consider a limitation of the sulfur content of unleaded gasoline to 200 and 100 ppm effective January 1, 1982 and January 1, 1984, applicable in the Bay Area, San Diego and South Coast Air Basins. 3. That the Board consider the adoption of the variance procedure given in Section IV of the staff report. 4. That the Board consider applying the present regulation limiting the sulfur content of unleaded gasoline only to gasoline sold in the San Francisco Bay Area, San Diego and South Coast Air Basins and Sacramento County. SUMMARY 1. Small refiners request exemption from the sulfur-content regulations because of financial hardship and a claim that there is a general lack of need for such a regulation. Kern river Local No. 1-19 of the Oil, Chemical and Atomic Workers International Union is concerned about possible loss of employment if small refiners are forced to close because of the sulfur and lead regulations. 2. Some refineries would face a problem in meeting an accelerated schedule for the sulfur regulation. To meet this difficulty, a proposed variance procedure is shown in the report that if adopted would permit such refiners to obtain enough time to build the necessary facilities. However, an accelerated schedule may not be necessary unless indicated by new medical evidence or air monitoring data. 3. The present sulfur regulation may not be needed outside of the San Francisco Bay Area, San Diego and South Coast Air Basins and Sacramento County because in the outside areas, average daily traffic volumes are less than one fifth of the maximum in the South Coast Air Basin. 4. Present information indicates that a limit of the sulfur content of unleaded gasoline of 200 and 100 ppm, effective January 1, 1982 and January 1, 1984 is needed in the San Francisco Bay Area, San Diego and South Coast Air Basins only. 5. The exemption from the regulation of small refiners in the South Coast Air Basin would defeat the purpose of the regulation. ITEM NO.: 75-16-4 Status Report on Standards for Abrasive Used in Abrasive Blasting Operations. RECOMMENDATION Informational Report. SUMMARY At the June 12, 1975 meeting the Board accepted from its Committee proposed standards for abrasives used in abrasive blasting operations. The Board directed the staff and the Committee to undertake certain actions and report back prior to the Board's consideration of adopting the proposed standards. This report is to advise the Board of the status of the requested actions. ITEM NO.: 75-16-6 Status Report on State Air Pollution Emergency Plan. RECOMMENDATION This is an informational report. SUMMARY Revisions to the Plan have been made to emphasize emergency protective measures that can be taken by individuals during periods of high air pollution and to augment abatement actions that could be taken during an air pollution disaster. Additional changes have been proposed and considered at a public hearing on August 20, 1975 to meet the requirements of the federal Clean Air Act. Source curtailment plans for APCDs in the South Coast Air Basin have been reviewed to estimate their effectiveness if it should be necessary to implement these plans. The data indicate that a reduction in hydrocarbon emissions from stationary sources could be as high as 50% if Stage 3 control actions are implemented.
