AGENDA INFORMATION SHEET AGENDA DATE: DEPARTMENT: ACM: November 8, 2004 Solid Waste Howard Martin, Utilities, 349-8232 SUBJECT Receive a report on bioreactor landfill technology, and its impact on the City of Demon landfill. BACKGROUND Bioreactor technology accelerates landfill waste decomposition, and accelerates biostabilization of leachate and organic constituents. Bioreactor landfills are controlled environmental systems that require proper operations management. There are benefits from operating a landfill with this technology. They include increased disposal capacity, a shorter period of post-closure maimenance, increased gas production for beneficial use, and longer site life. These issues, and the implememation of this technology at the City of Demon landfill, will be discussed during the City Council work session. RECOMMENDATION None. FISCAL INFORMATION None. EXHIBITS 1. Summary 2. Presentation Respectfully submitted: A. Vance Kemler Director, Solid Waste Services Bioreactor Landfill Technology Summary Municipal solid waste (MSW) landfills are designed, constructed and operated in compliance with the federal regulations promulgated under subtitle D of the Resource Conservation and Recovery Act (RCRA) and the associated state rules. A Bioreactor Landfill is a sanitary landfill that utilizes methods to enhance the biodegradation process conducted by the indigenous microbiological population. This process rapidly stabilizes the decomposable organic and inorganic waste constituents. The bioreactor technology expands upon a currently approved method of recirculating leachate through the waste. The bioreactor landfill adds additional amounts of aqueous based liquids to a level that provides an optimal environment for the microorganisms to achieve a faster rate of metabolism. This increased metabolic rate increases the production of methane gas, which can be captured for a beneficial use. There are three major advantages of operating a landfill as a bioreactor. The accelerated biodegradation provides methane gas in quantities for beneficial use. A more rapid stabilization of leachate and the waste reducing the length of time the site will require monitoring. The airspace gained to provide a longer site life. Site Life Bioreactor landfills are projecting a landfill airspace savings ranging from 15% to in excess of 30%, depending on the site's waste characteristics and operating variables. Utilizing bioreactor technology offers the potential of increasing the site life. Since the degradable waste will be well decomposed, the bioreactor process offers an additional opportunity in extending the site life, if it becomes economically feasible, through mining the stabilized waste and reusing the landfill airspace. Beneficial Use of Landfill Gas The bioreactor process achieves the production of methane gas in large enough quantities to use it as a beneficial energy source. The gas can be used to produce electricity through a generator, used to fired boilers or be sold directly to a gas user. EXHIBIT 1 Post-Closure Site Maintenance Currently, Subtitle D landfills are required to monitor and maintain their sites for 30 years after closure. This is to ensure no contamination of the environment has occurred and stabilization of leachate has been achieved. A bioreactor landfill may achieve stabilization in 5 to 10 years. With the approval of the regulatory agency, post closure monitoring and maintenance could be eliminated after stabilization is reached. The bioreactor advantages offers the City a substantial financial savings potential which will offset the increased operating costs of the bioreactor. L_ Z._I LULL AGENDA INFORMATION SHEET AGENDA DATE: DEPARTMENT: ACM: November 8, 2004 Utility Administration Howard Martin, 349-8232 SUBJECT Receive a report and hold a discussion regarding status of Green Building Program. BACKGROUND The City of DeNon has been exploring options for implememing a Green Building Program for some time. Most Green Building programs include energy efficiency, water conservation, site selection, building orientation, construction practices and materials selection. There are many Green Building programs in place across the United States. Programs range from mandatory, in Frisco, Texas to checklist based programs in Atlama, Georgia and Scottsdale, Arizona. Over the past several momhs staff has presemed several examples of green building programs to the City Council Environmem Committee. The Committee has requested additional information regarding Code Compliance, Energy Star, and additional conservation measures that may be implememed as well as input from local builders. Code comparison information is available and meetings with builders are curremly planned for early December. The City of DeNon curremly uses the Imernational Energy Conservation Code (IECC) 2000. The Building Inspections Division is curremly reviewing the IECC 2003 possible adoption with local amendmems. A 2004 IECC Supplemem has been released that is also being reviewed. The opportunity exists to discuss adopting the IECC in conjunction with the developmem of a Green Building Program. In addition to a Green Building Program for residential construction the option exists to adopt a commercial green building program such as LEED (Leadership in Energy and Design). LEED is a checklist-based program whereby buildings may earn various levels of rating and recognition based on building design and performance. The City of DeNon could consider the adoption of an internal Green Building Policy for new construction. This might take the form of a resolution adopting the use of Green Building Practices, or adopting LEED as a minimum requirement. The next steps will be to: · Idemify specific costs associated with adopting most recem version of IECC or Energy Star · Draft a Green Building Program including applicable Energy Efficiency programs and/or codes, and possible additional conservation measures and practices · Hold a series of meetings with local builders to review draft plan work together to determine best possible additions for conservation and practices · Presem findings to City Council Committee for the Environmem EXHIBITS: 1.

ENERGY STAR is the government-backed symbol for energy efficiency. It identifies new homes and over 30 types of products that are energy efficient without ERGY STAR? sacrificing the features, quality, and personal comfort that today's consumers expect. Products that can earn the ENERGY STAR include appliances, lighting, home office equipment, consumer electronics, and heating and cooling equipment. The ENERGY STAR tabel on a new home means that it is significantly more efficient than a standard home:* HOMES THAT HAVE EAR. Homes that have earned the ENERGY STAR perform better for you and the environment Ihanks to a variety of energy efficient features that can include: INCREASED INSULATION Improved and effective use of insulation helps achieve even temperatures throughout the house while using less energy~ The result is lower utility costs and a quieter, more comfortable home. HIGH-PERFORMANCE WINDOWS High-performance windows help keep heat in during winter and out during summer, They also block damagin9 ultraviolet sunlight that can discolor carpels and furniture, THE ENERGY STAR TIGHT CONSTRUCTION AND TIGHT DUCTS Tight ducts and tight construction help eliminate drafts, moisture, dust, pests, and pollen. 7his improves comfort and the quality of indoor air, while lowering maintenance costs. ENERGY-EFFICIENT HEATING AND COOLING EQUIPMENT More efficient and properly installed heating and cooling systems use less energy, which reduces utility biles. These systems also turn on and off less frequently, removing mere humidity and providing better comfort. *ENERGY STPtR labeled homes are typically at least 30 percent more energy efficient than standard homes.
