Public Comments None. Real Estate, Environmental & Planning Committee Minutes December 13, 2016 Page 2 3.* Review CORSolutions' organic recycling proposal for Central San Buffer Land Ms. Gemmell introduced the item, and explained that this is a preliminary look at the proposal, as staff and CORSolutions have not yet inquired about permits. Mr. Scott presented the information included in the agenda materials, explaining that his proposal is to lease Central San buffer land for a transfer station that would obtain repurposed organic recycling materials via truck that would be in turn distributed via rail or barge. He also distributed two additional handouts, which are attached. He explained that certain products, such as soil, concrete and asphalt, could be repurposed if there was a means to distribute the product to the users (developers). Often, trucking expenses are very high, and there are also locations that are being developed that trucks cannot reach. Mr. Scott stated that the Interstate 680 corridor along Highway 4 is a prime location as a transportation hub. Mr. Tully explained that the current proposed site is zoned public/semi-public, which would not allow for use by private commercial business, unless there is a finding for public benefit. Other sites may be more compatible. Member Nejedly said he would be open to the idea, but the proposal is still in the early stages. Chair McGill agreed, saying that he is in support of opportunities to generate revenue from the buffer land, and he is in favor of environmentally focused projects. He suggested that Mr. Scott return with a simplified and more defined proposal. COMMITTEE ACTION: Discussed and provided input to staff. 4.* Discussion on concept of gasification Mr. Bailey introduced the item, stating that the Board will soon have to decide on how to move forward with the treatment plant solids handling process. The gasification process could potentially provide an option for energy recovery from processing the solids. Member Nejedly stated that he will be traveling out of state for his work at Mt. Diablo Resource Recovery to tour a facility using this process and will report back with his findings at a future meeting. Ms. LaBella presented information on the concept of gasification and the project drivers and benefits at Delta Diablo (attached). She also explained how this process might benefit Central San, and what the next steps would be. Mr. Petit stated that he would like to run a pilot sooner than later. He would like to begin preparing two Request for Proposals (RFPs) and an implementation plan. The first RFP would be to hire a consultant to assist Central San in defining the project and the second would be to prepare an RFP for the implementation of a gasification project which would Real Estate, Environmental & Planning Committee Minutes December 13, 2016 Page 3 likely follow a Private Public Partnership (P3) model. Chair McGill said he was supportive of preparing an RFP, and Member Nejedly agreed. COMMITTEE ACTION: Discussed and provided input to staff. 5. Receive update on current Resource Recovery projects Ms. LaBella stated that Item 4 was part of her update on the projects she is currently working on. In addition, she is following up on Central San's Wholesale Recycled Water Opportunities Study recommendations, specifically refineries, Indirect Potable Reuse/Direct Potable Reuse (IPR/DPR)projects, and recycled water for agricultural use. She is also continuing her work with the Diablo Country Club (DCC) Satellite Water Recycling Facility(SWRF), and providing site support for the Recycled Water Program. COMMITTEE ACTION: Received the update. 6. Update/debrief on meetings of Bay Area Clean Water Agencies (BACWA) Ms. Schectel referred to the discussion at the last Committee meeting regarding Rule 11-18, which is proposed to reduce air toxic emissions from existing facilities. She explained that the Bay Area Air Quality Management District (BAAQMD) recently held a hearing where she commented that Central San supports the intent of the rule, but not how it is currently written and identified three key issues (timing, scope and cost). Another BAAQMD hearing will be held after the first of the year and she will continue to track rulemaking developments Ms. Schecte/also noted that a white paper is being developed on nutrients, stating a draft is expected to be available in 2017. COMMITTEE ACTION: Received the update. 7. Announcements a. Future scheduled meetings: 2017 meetings - to be determined. COMMITTEE ACTION: Received the announcements. 8. Suggestions for future agenda items None. 9. Adjournment— at 4:24 p.m. * Attachment Item 3. (Committee Handout) THE UnDE GROUP Cryogenic Grinding. Fine-Particle Pulverization with Nitrogen or Carbon Dioxide. Before After Plastic,elastic,and heat-sensitive materials have properties that make fine grinding quite difficult,which can create additional process and performance difficulties.with cryogenic size reduction, Linde offers a process which economically pulverizes many different materials with low-temperature gases.This process can provide benefits such as reduced energy costs and increased production rates. Cryogenic gases provide flexibility across a wide range of grinding temperatures.For example,carbon dioxide is traditionally used for cooling in the spice industry. The process usually utilizes fine impact mills,although other types of milling systems can also be applied. Linde has decades of experience in the application of cryogenic grinding in customers'facilities. This expertise includes the selection,implementation,and optimization of suitable cryogenic grinding processes. ............................. .. .. ..................... ........ ..................._._...._.............................. _.._......._...............................................

Traditional grinding for grinding spices processes generate heat that can degrade or reduce the volatility of a spice's heat sensitive constituents such as aroma and flavor. The spices are frozen with cryogen such as liquid nitrogen(LIN/N2)or carbon dioxide(CO2)as they are ground into a fine powder. This process preserves the quality of aroma and flavor within the product without damaging or altering the chemical composition of the spices. Spices are fed through a hopper to a conveyor system. While moving along the conveyor,the spices are sprayed with the appropriate amount of cryogen.The material is then moved to a stainless steel auger that transports, grinds,and mixes the product and cryogen for an efficient cooling process.The cryogen absorbs the heat and is vaporized to a gaseous state,which is then expelled from the system through an exhaust system. The results are high quality spices at controlled partial sizes with no evaporation of essential values and negligible loss of volatile components. Cryogenic grinding data (e.g. pepper) Particle Size 700 pm Production Rate 1654 Ib/h Nitrogen Consumption 0.25 Ib/Ib pepper Driving Power 35 kW(47 hp) Process example for A dosing wheel meters the plastic pellets,e.g.polyethylene or polyamide,into the mill.The grinding heat would grinding thermoplastics normally melt the thermoplastics,preventing the possibility of fine-particle grinding.However,cryogenic gases prevent this by embrittling the material in a cooling conveying screw.The cryogenically ground plastic and the gas are collected in a bin.The pulverized product is then further processed through a cellular wheel sluice. The mill gas is purified with a filter and is released.The remaining gas is recycled back into the mill for heat integration. The results are finely ground thermoplastics that maintain the quality of the processing equipment by preventing melted material from impeding the system.
