State of California AIR RESOURCES BOARD Sacramento Community Center Sacramento Room (2nd floor) 1100 14th Street Sacramento, CA December 15, 1976 10:00 a.m. AGENDA 76-24-1 Minutes of October 5, Board Meeting. 76-24-2 Status Report on Implementation of Emergency Plan. 76-24-3 Status Report on Continuous Emission Monitoring of Existing Sources. 76-24-4 Status Report on Organic Solvent Regulations. 76-24-5 Status Report on Certification Procedures for Vapor Recovery Systems at Bulk Plants and Terminals. 76-24-6 Report on Local upset/breakdown regulations. 76-24-7 Other Business ITEM NO.: 76-25-2 Status Report - Implementation of California Air Pollution Emergency Plan. RECOMMENDATION Informational Report. SUMMARY This staff report presents the status of the district's emergency regulations and the abatement plans submitted by affected sources; summarizes the prediction and occurrence of episodes in 1976; and discusses Regulation VII of the Southern California Air Pollution Control District (APCD). The staff has determined that present APCD regulations are not adequate to implement the California Air Pollution Emergency Plan. This inadequacy is especially critical in the Southern California APCD where the potential for severe air pollution episodes is the greatest. ITEM NO.: 76-25-3 Status Report on Continuous Emission Monitoring of Existing Sources. RECOMMENDATION Informational Report. SUMMARY Prior to October 27, 1975, when the Air Resources Board made the findings that in-stack monitors are available, technologically feasible and economically reasonable for installation on certain specified sources, most local districts had regulations which required sources to install emission monitors upon the finding by the APCO that such monitors are available and should be installed. After the ARB made its findings, 13 APCDs revised their regulations to require continuous in-stack monitoring for sources that were identified in the ARB findings. On October 6, 1975, the EPA promulgated in-stack monitoring requirements which were more extensive than the requirements contemplated by the ARB findings and by the regulations adopted by the local districts. In view of the differences between State and Federal requirements, some local districts expressed the desire that these differences be resolved before adopting or revising their regulations. The ARB submitted the regulations of some districts to the EPA for approval, but did not receive comments regarding their acceptability until September 1976. In the next three months, the staff will evaluate the EPA requirements and work with local APCDs for the adoption of emission monitoring regulations that meet state and federal requirements. ITEM NO.: 76-25-4 Status Report on Organic Solvent Regulations. RECOMMENDATION Informational Report. SUMMARY Organic emissions are a major contributor to photochemical smog in California. Substantial reductions in these emissions have been obtained through the use of pollution control devices on motor vehicles and the enactment of organic solvent regulations for stationary sources. However, further reductions are needed to achieve the state and federal oxidant standards. An organic solvent regulation study group was formed in April 1976 to develop model rules to reduce organic emissions from organic solvents. The study group consists of representatives from local districts and the ARB staff. A preliminary inventory indicates that architectural coatings and paint spray booths are among the largest contributors of organic emissions, and rules will be developed for these sources first. As the study progresses, degreasing, dry cleaning and other organic solvent operations will be investigated and model rules will be developed. ITEM NO.: 76-4-5 Status Report on the Development of Proposed Certification and Test Procedures for Vapor Recovery Systems for Gasoline Delivery Tanks, Bulk Plants and Terminals. RECOMMENDATION Schedule a public hearing to consider the adoption of the proposed certification and test procedures. SUMMARY State law requires the Board to adopt procedures for the certification of gasoline vapor control systems for the control of gasoline vapor emissions during gasoline marketing operations, including storage, transport and transfer operations. The Air Resources Board has adopted certification and test procedures for gasoline vapor recovery systems at service stations. To complete compliance with state law, the staff has been working with industry and governmental agencies to develop certification and test procedures for gasoline vapor recovery systems for delivery tanks, bulk plants and terminals. Tentative proposed test procedures for these gasoline marketing operations have been developed. This report summarizes the staff activities which preceded the development of the test procedures. ITEM NO.: 76-24-6 Report on Local Upset/Breakdown Regulations. RECOMMENDATION Approve the staff's draft upset/breakdown rule (with modifications where necessary) suggested for statewide application and, following a workshop with the APCDs, EPA, industry representatives, and interested members of the public, receive for review and approval at the March, 1977 Board meeting a suggested rule to be adopted by the APCDs. SUMMARY A staff review of upset/breakdown rules and practices in effect in the various APCDs throughout the state has revealed major deficiencies which seriously undercut effective enforcement of the emission limitations in state law and local rules and regulations. These deficiencies consist of excusing avoidable or negligent violations, allowing administrative or informal variances to be granted by the APCO, inadequate reporting requirements, the lack of a defined and enforceable emergency variance procedure before the hearing board, the inclusion of scheduled maintenance and startup or shutdown, an unclear relationship to the statewide nuisance and Ringelmann 2 requirements, and a lack of interdistrict consistency. The staff suggests that a uniform model rule, without these deficiencies, be approved by the Board. The staff has prepared a draft suggested rule for the Board's review and approval, the adoption of which would have no significant local cost or personnel impacts. The staff proposes a public workshop for consideration of the draft suggested rule, followed by board approval at its March, 1977 meeting, of a rule for adoption by the APCDs.
