The Environmental Protection Agency held a hearing on the California waiver application in Los Angeles on January 26 and 27. During the hearing a number of relatively minor inconsistencies between the State and Federal test procedures were aired. Objections were also raised to several technical and procedural provisions. At the conclusion of the hearing, the Hearing Officer, Mr. Megonnell, agreed to keep the record open until February 22 to afford an opportunity to the Board to consider procedure changes. ITEM Staff Report on Proposed Guidelines for Agricultural Burning. Chapter 1579 of the Statutes of 1970 (AB 16, Ketchum) contains among others, provisions directing the Board to report to the Legislature on the progress in the development of guidelines for regulating agricultural burning. A report was submitted to the Legislature on January 15, 1971. A copy of the report, which includes a set of preliminary guidelines, is attached to this report. ITEM Staff Report on Motor Vehicle Emission Standard for Lead. At the January 20, 1971 Board meeting, a public hearing was held on a proposed definition, and a motor vehicle emission standard for lead. After closing the public hearing, the Board requested of the staff suggestions on a numerical value for the emission standard. Because of the short time available, it was not possible to conduct extensive experimentation to develop the necessary data on which such a standard could be based. Instead, a literature review of recent pertinent studies was made. Based on such a review, the staff concluded that a motor vehicle emission standard for lead could be established at 0.01 gram per mile. the standard would refer to lead bearing particles less than one micron ( ) emitted from vehicle exhaust as determined by the procedure described by Habibi, et al (1).
