CONTRA COSTA COUNTY HAZARDOUS WASTE SECTION. ON FORMATION OF AN ADVISORY COMMITTEE FOR WASTE MINIMIZATION PROGRAM AND REOUEST FOR SANITARY DISTRICT REPRESENTATIVE ON THAT COMMITTEE Ms. Gina Gargano, of the County Hazardous Materials Section, thanked the group for the opportunity to address the Special Districts in Contra Costa County on the Waste Minimization Program. Ms. Gargano stated that the existence of this group expedites her job by providing a forum for selection of a sanitary district representative for the Implementation Task Force. Ms. Gargano reported that the Contra Costa County Hazardous Materials Plan was one of the few approved by the State of California. The Plan calls for a 30 to 40 percent waste reduction in the County by the year 2000. Ms. Gargano provided background on the Waste Minimization Program. The County Hazardous Materials Section will provide workshops on waste reduction for the generators of small quantities. The County assumes that large quantity generators have technical knowledge. Waste management plans will be discussed with large quantity generators, and they will be asked to set specific goals for the future. The County will track them to be sure they meet the goals. Ms. Gargano stated that an Implementation Task Force is being developed to assist in reaching the goals of the Waste Minimization Program. Ms. Gargano distributed a brochure on the program and described the Implementation Task Force. Ms. Gargano requested a sanitary district representative to serve on the task force. The representative should have technical background and field experience. Chairperson Rainey stated that if the representative were selected from this group, they could report back to us and convey any comments or concerns that we have to the Implementation Task Force. Following discussion, there was a consensus that West Contra Costa Sanitary District be designated to, represent the Q~ 2ß 9,0 J ;, i " : 78 J sanitary districts on Implementation Task Force. the Hazardous Waste Minimization V. SLUDGE DISPOSAL UPDATE Mr. Robert Baker, of Central Contra Costa Sanitary District, stated that sludge disposal was mentioned frequently as an area of common concern to special districts. A panel of representatives from Delta Diablo Sanitation District, East Bay Municipal utility District, and Central Contra Costa Sanitary District will provide an update on the current sludge disposal methods being utilized and alternatives" being explored. 1. EAST BAY MUNICIPAL UTILITY DISTRICT Ms. Suzanne Schweitzer, of East Bay Municipal Utility District (EBMUD) , stated that sludge is approximately 80 percent water. Regulations require that it must be less than 50 percent water for landfill disposal. Ms. Schweitzer briefly reviewed the federal regulations and their potential impacts. At EBMUD, 25 percent of the sludge is composted and the remaining' 75 percent goes to a landfill. EBMUD has developed a long-term sludge management plan. The goal of the plan is to reduce the percentage of sludge going to a landfill, to increase the amount of sludge being composted, and to diversify by identifying a third disposal option. Ms. Schwei tzer described the composting operation at EBMUD. In an effort to diversify disposal options, EBMUD is looking at mixing sewage sludge with cement kiln dust to reduce moisture content to 50 percent solids. 2. DELTA DIABLO SANITATION DISTRICT Mr. Robert Simmons, of Delta Diablo Sanitation District (DDSD) , provided background on Delta Diablo Sanitation District and its wastewater treatment acti vi ties. DDSD digested sludge has been disposed of at GBF Landfill in Antioch since 1982 when DDSD first came on line. Because of escalating costs and problems associated with landfill disposal of sludge, DDSD developed a work plan to evaluate alternative means of sludge disposal. Dedicated land disposal had been considered the most viable option but because of problems encountered at the Regional Board level, this alternative has been placed on the back burner. An agricultural land disposal alternative was then considered. At this time, DDSD is looking at mechanical heat drying of sludge to obtain 50 percent solids concentration. DDSD hopes that the agricultural land disposal alternative will come to'fruition but the District will continue to pursue other alternatives such as mechanical heat drying. 3. CENTRAL CONTRA COSTA SANITARY DISTRICT Mr. Robert Baker, of Central Contra Costa Sanitary District (CCCSD) , described the service area and operations at CCCSD. CCCSD incinerates sludge in two multiple hearth furnaces. The ash is disposed of at a landfill. Ash dusting problems have been encountered. CCCSD is currently working on a process to mechanically mix water into the ash to minimize this problem. Mr. Baker reported that CCCSD completed a Solids Handling Facilities Plan to analyze the viability of continued incineration and to develop and analyze the cost effectiveness of alternatives. Using the EPA risk assessment model, it was concluded that incineration is viable but backup processes should be developed. Advanced alkaline stabilization using lime and thermal mechanical drying are alternatives currently being considered. Vallejo Sanitary District has agreed to allow CCCSD to use their sludge disposal site for five years on an emergency basis. The District is now working on permits for that alternative. The presentations were followed by questions from the floor. The fuel used in the thermal drying alternative, transportation of sludge to crops, the concern for the public perception of problems associated with use of composted sludge on the food chain, and the ,04 ." "" ~ .. 26 " .. 1.. ~ 90 79 composting process were discussed. Chairperson Rainey thanked Ms. Schweitzer and Messrs. Simmons and Baker for their presentations. VI. PLASTICS RECYCLING PROPOSAL Ms. Avon Wilson, of the Contra Costa County Solid Waste Commission and Plastics Recycling Task Force, addressed the group stating that the Plastics Recycling Task Force was formed to develop an aggressive program to recycle plastics. WTC and Dow currently have a plastics recycling pilot program in the City of Walnut Creek. WTC has proposed to recycle the County's entire plastic waste stream. They requested a five-year exclusive contract. Ms. Wilson indicated that while this proposal was intriguing, it raised a series of questions. County representatives are now meeting with franchisers, collectors, and processors on this issue. A Request for Qualification/Request for Proposal (RFQ/RFP) is being developed for use in identifying and evaluating alternatives. Ms. Sara Hoffman, County Solid Waste Manager, distributed and reviewed the draft RFQ/RFP. Proposals will be evaluated on both technical and marketing feasibility. Ms. Hoffman requested any comments on the draft RFQ/RFP or ideas for distribution. In the discussion that followed, questions concerning by-products of the plastics recycling process and environmental impacts were raised. VII. JPA UPDATE INCLUDING ROLE AND AUTHORITY OF SANITARY DISTRICTS IN SOLID WASTE PLANNING Mr. Paul Morsen, of Central Contra Costa Sanitary District, reported that it has been determined that no amendments will be needed in the Solid Waste JPA to comply with Statutes of 1989, Chapter 1095 (AB 939). On Monday, May 14, 1990, the Environmental Affairs Committee of the Board of Supervisors will discuss the Solid Waste JPA. Chairperson Rainey reported that the Board of Supervisors has appointed the AB 939 Task Force. Chairperson Rainey briefly reviewed the appointees to the Task Force and the sectors they represent. The first meeting of the Task Force is scheduled for Wednesday, May 16, 1990, at 3 p.m. at the Martinez Police Station. VIII. STATUS OF AB 2588. AIR TOXICS HOT SPOTS Mr. Robert Baker, of Central Contra Costa Sanitary District, reported that AB 2588, Air Toxics Hot spots, was passed in California in 1987. Chapter 1252 of the Statutes of 1987, AB 2588 required that measurements be made to assess the amounts of toxics in the air from treatment plants. Health assessments must then be done and if a certain level exists, the treatment plant neighbors must be notified by letter of the risks. Mr. Baker reviewed the status of testing and risk assessments, the implications of this work, and the need for emission control equipment at treatment plants. IX. DIRECTORY OF SPECIAL DISTRICTS IN CONTRA COSTA COUNTY Chairperson Rainey referred to the draft Special District Directory form in the back of the agenda packet and asked whether a directory of this type would be of benef it to the special districts. Special district representatives present endorsed the concept of a directory.
