SUMMARY ITEM #89-11-1 Public Meeting to Consider a Draft Report: The Landfill Gas Testing Program: A Second Report to the California Legislature. RECOMMENDATION To approve the report and direct the staff to transmit it to the Legislature by July 1, 1989. DISCUSSION This is the second report to the California Legislature summarizing the status and results of testing for toxic gases in and around solid and hazardous waste disposal sites in California. The testing was required by AB 3525 (1984) and AB 3374 (1986). Based on survey information from the districts, more than 1800 landfills were evaluated and 664 sites were found to require testing. In the 24 months since completion of the testing guidelines required by AB 3374 (9186), over 75 percent of the sites 513 sites) have been tested or have testing in progress. The report summarizes the testing results for the 356 sites that were submitted to the ARB as of March 1, 1989. Further analysis of the data is necessary because the large majority of the information was received during the time the report was being prepared. Based on a preliminary analysis the staff finds: (1) Specified contaminants found to be indicators of hazardous waste are present in the majority of the landfills tested, regardless of whether the site accepted hazardous or non-hazardous waste. (2) Hazardous and non-hazardous sites appear to be similar in their ability to produce toxic gases with non-hazardous sites in some instances having higher peak concentrations of many of these gases within the landfill than hazardous waste sites. (3) In some cases, toxic gases escape from landfills and disperse into the ambient air. (4) Methane at concentrations exceeding 5 percent was found to be migrating off-site underground at approximately 20 percent of the sites. The report contains two recommendations. First, districts should become more involved in the permitting of landfills. The districts should consider adopting rules to require gas collection and disposal systems where appropriate at new or expanded landfills. Second, for existing sites, the districts should continue to evaluate the test data and, by the end of 1990, identify sites that need further testing or other remedial action. ITEM #89-11-2 Public hearing to Consider the Adoption of Classification of Areas of the State as Attainment, Nonattainment, and Unclassified for State Ambient Air Quality Standards for the California Clean Air Act of 1988. RECOMMENDATION The staff recommends that the Board adopt the proposed designations. DISCUSSION The California Clean Air Act of 1988 (the "Act") requires the Board, in consultation with air pollution control districts, to designate each area of California as either attainment, nonattainment, or unclassified for pollutants with state standards listed in Section 70200, Title 17, California Code of Regulations. These designations must be made by September 30, 1989. the implications of each type designation are: 1) The designation of an area as attainment indicates that no state standard for that pollutant is violated in the area. 2) The designation of an area as nonattainment indicates that a state standard for that pollutant is violated in the area. The Board may require districts to collect fees from holders of permits for sources in nonattainment areas which emit 500 tons per year or more of that pollutant or its precursor(s). Also, proposed new and expanded stationary sources would be subject to new source review rules. Finally, if the designation is for ozone, carbon monoxide, nitrogen dioxide, or sulfur dioxide, and attainment plan must be submitted to the Board before July 1, 1991. 3) The designation of an area as unclassified indicates that the data available do not support an attainment or nonattainment designation. The proposed designations are consistent with the Act and with the proposed criteria presented in Board Item #89-10-3, Criteria for Designating Areas of California as Attainment, Nonattainment, or Unclassified for State Ambient Air Quality Standards as Required by the California Clean Air Act of 1988. ITEM #89-11-3 Public Hearing to Consider the Adoption of Sections 90620-90623, Title 17, California Code of Regulations, Regarding the Atmospheric Acidity Protection Program. RECOMMENDATION Staff is recommending adoption of emissions fee regulations for fiscal year 1989-90. DISCUSSION In the Atmospheric Acidity Protection Act of 1988 (Stats. 1988. ch. 1518, Health and Safety Code Sections 39900-39911), the legislature made a finding that the deposition of atmospheric acidity resulting from other than natural sources is occurring in various regions of California, and that the continued deposition of this acidity, alone or in combination with other man-made pollutants and naturally occurring phenomena, could have potentially significant adverse effects on public health, the environment and the economy. The Legislature directed the Board to adopt and implement the Atmospheric Acidity Protection Program, to determine the nature and extent of potential damage to public health and the state's ecosystems which may be expected to result from atmospheric acidity, and to develop measures which may be needed for the protection of public health and sensitive ecosystems within the state. To enable the Board to carry out these activities, the Act authorized the Board to require the districts, beginning July 1, 1988, to impose additional variance and permit fees on nonvehicular sources authorized by permit to emit 500 tons per year or more of either sulfur oxides or nitrogen oxides. The total amount of funds collected from additional fees, exclusive of district costs, shall not exceed $1,500,000 for any fiscal year or the amount appropriated from state funds by the Legislature for the Atmospheric Acidity protection program, whichever is less. Proposed Sections 90620-90623, Title 17, California Code of Regulations would apply to fiscal year 1989-90. The proposed regulations provide for the collection of fees by the districts and forwarding of the fees to the Air Resources Board for deposit into the Air Pollution Control Fund, for the collection of additional fees by the districts to cover administrative costs, and for exemption of districts from the fee collection requirements for good cause. The regulations would specify that compliance with the fee requirements shall be based on the amounts of emissions as determined by the Board's Executive Officer on march 31, 1989 and that fees shall be collected from sources identified, after adoption of the regulations, as having emitted 500 tons or more per year of sulfur oxides or nitrogen oxides in 1987. The regulations would also require the collection of fees from sources identified after March 31, 1989. The fees to be collected by districts are based upon estimated emissions data of sulfur oxides and nitrogen oxides from sources emitting 500 tons or more per year of either of the two pollutants for calendar year 1987. The specific dollar per ton value was calculated by dividing $1,500,000 (amount to be collected) by the total estimated emissions of sulfur oxides and nitrogen oxides from sources emitting 500 tons or more per year. The proposed fees have been adjusted by a 25 percent contingency factor to cover unforeseen under collection for reasons such as unanticipated closings of businesses. No significant adverse impacts are anticipated by the Board's adoption of the proposed emissions fee regulations. ITEM #89-11-4 Public Hearing to Consider the Adoption of Permit Fee Regulations for Nonvehicular Sources Pursuant to the California Clean Air Act. RECOMMENDATION The staff recommends that the Board adopt the proposed regulations for recovery of costs incurred by the Air Resources Board (ARB) during the fiscal year 1989-90 to implement those provisions of the California Clean Air Act related to nonvehicular sources. DISCUSSION The California Clean Air Act requires the ARB to develop new programs and to expand existing programs to address the problem of air pollution in California. To partially defray the additional costs to the ARB of implementing programs and activities related to nonvehicular sources pursuant to the Act, Section 39612 of the Health and Safety Code authorizes the ARB to require districts to collect fees from the holders of permits of sources which are located in nonattainment areas and which emit 500 tons or more per year of any nonattainment pollutant or precursor. The staff's proposal would implement Section 39612 by requiring districts to collect the fees authorized by the Act and to transmit the fees to the ARB for deposit into the Air Pollution Control Fund. Districts would be required to assess each qualifying facility a fee of $10.89 per ton of emissions of nonattainment pollutants and precursors. The staff has developed the proposed fee regulation in consultation with affected districts. Also, the staff held a public consultation meeting to which approximately 1,500 industries, members of the public and districts were invited. SUMMARY AND IMPACTS OF PROPOSED BOARD ACTION Adoption of the proposed regulations are not expected to result in any adverse health, safety or environmental impacts. The cost per facility ranges from approximately $5,400 for the smallest facility subject to the regulations to approximately $316,000 for a multi-facility business. No small businesses have been identified that would be subject to the fees.
