PUENTE HILLS LANDFILL DISCOVER HOW THE LATEST TECHNOLOGIES ARE KEEPING NEIGHBORHOODS CLEANER AND GREENER PEOPLE SAY, “SOLID WASTE MANAGEMENT IS A DIRTY BUSINESS.” WE SAY, “RUBBISH.” YESTERDAY’S DISPOSAL SITE. GOOD NEIGHBOR POLICY. Even the name sounds dirty. The Puente Hills Landfill has been owned and operated by And indeed, in the old days, the Sanitation Districts of Los Angeles County (Sanitation Districts) disposing of solid waste was since 1970. Beyond managing the sanitary disposal of solid waste, a the Sanitation Districts are committed to being a good neighbor to its “dirty business” with few environmental or health surrounding communities. regulations in place to protect the public.

The Sanitation Districts are made up of a partnership of 23 independent special districts serving about 5.7 million people in Los Angeles County. The service area covers approximately 820 square miles and encompasses 78 cities and unincorporated territory with the county. The comprehensive solid waste management system is comprised of three active sanitary landfills, two recycle centers, three transfer/materials recovery facilities, and three landfill gas-to-energy facilities. The Districts also maintain three closed sanitary landfill sites and, through joint venture agreements, participate in the operation of two refuse-to-energy facilities. Groundwater Sampling A highly qualified group of individuals staff the Sanitation Districts. The roster includes engineers, environmental monitoring technicians, recycling specialists, engineering designers, hydrogeologists, engineering geologists, scientists, and skilled operations personnel. Specialty consultants are used when necessary to support the staff. All of which leads to another important way the Sanitation Districts serve their communities… the creation of jobs. INTO THE FUTURE. As the population grows, more trash gets generated and there are fewer places to build landfills. It’s a complex problem that the Sanitation Districts have been hard at work on, implementing programs that offer real solutions. As capacity is reached at the Puente Hills Landfill, the new “Waste-by-Rail” program will continue the clean management of solid waste by loading it onto rail cars in sealed containers and delivering it to remote landfill sites. When the Puente Hills Landfill is closed for good, the facility will continue to be monitored and maintained by the Sanitation Districts to ensure environmental protection. The Los Angeles County Department of Parks and Recreation will determine, along with input from the public, the appropriate use of the site for surrounding communities to enjoy.

That’s the permitted daily disposal capacity of the Puente Hills Landfill. And make no mistake, every ounce of it is carefully managed by the Sanitation Districts, where dedicated teams of professionals develop—and apply—the best waste management techniques and practices available in the nation. SINGLE POINT OF ENTRY. Key to the process is making the operation as “invisible” as possible to the surrounding neighborhoods. This begins at a single point of entry, just off the freeway, that all trucks must use to enter and exit the landfill to ensure traffic in the area is not impacted. This entry point is also where trucks are weighed and scanned for radioactive material, which, if found, is pulled out of line and turned over to the appropriate regulatory agencies. Earthen berms block views of the disposal operations from surrounding areas and minimize equipment noise. Extensive landscaping screens the view of truck traffic from below the site. Native plants are used in appropriate areas to provide a natural look. GROUNDWATER PROTECTION PLAN. Groundwater protection at the landfill is so important that the Sanitation Districts have implemented several redundant features for extra precaution. First, the site itself was chosen for its natural containment geography and because it is not located over a water supply. Second, incoming refuse is inspected for the presence of unacceptable or hazardous waste. Third, underground barriers have been constructed downstream of fill areas to contain subsurface water on-site. Fourth, impermeable liner systems that meet stringent regulatory GAS COLLECTION PIPE standards are installed at the GAS TO GAS WELLS landfill. Finally, to check the & TRENCHES ongoing effectiveness of these GROUNDWATER MONITORING measures, an extensive system REFUSE WELLS LINER ALLUVIUM of monitoring wells surrounds BEDROCK the landfill, where constant testing provides assurance of GROUNDWATER EXTRACTION WELLS environmental protection. SUBSURFACE BARRIER GAS MONITORING PROBE BUILDING THE CELLS, KEEPING IT CLEAN. Refuse doesn’t just vanish. It gets crushed and compacted, then covered with a cap: 6 to 12 inches of clean soil or other suitable cover materials. This process is done in manageable sections known as “cells.” Each cell contains a day’s worth of refuse cleanly encapsulated. While the refuse is being compacted and covered (photo above), water trucks continually moisten the roadways and disposal area with recycled wastewater to reduce dust. The cells are carefully aligned and layered in order to most efficiently “build” the landfill. UNDER CONTROL. Odor, dust and litter control are important elements in maintaining good air quality. Inactive areas are landscaped to minimize dust. Maintenance crews police the landfill and nearby surface streets for litter. Moveable recycled plastic fences also surround the operation areas to capture blowing litter on windy days. There’s even an innovative bird control program. Seagulls are discouraged with a system of poles and strings that disrupts their flying patterns. CNG Bulldozer at refueling station Clean Fuels Facility LANDFILL GAS RECOVERY. Extracting resources from the landfill operation is key to the Sanitation Districts’ management plan. Through the Landfill Gas Recovery infrastructure, the gas generated by the decomposition of organic material is collected through a network of more than 1,350 wells, 95 miles of underground trenches, and 34 miles of collection pipes. A team of engineers and technicians continuously monitors the entire gas collection system. The collected gas is converted to clean burning vehicle fuel and electricity. SHARED RESOURCES. Part of Sanitation Districts’ mission is to shepherd resources that might otherwise be wasted. Recycled wastewater, pumped in from the Sanitation Districts’ nearby San Jose Creek Water Reclamation Plant, is used for all non-potable water needs such as dust control and on-site irrigation. It’s also used as cooling water at the landfill’s energy recovery facility. Electricity generated at the landfill is used for power at the water reclamation plant. IN THE LAND OF OAKS. The majestic oak. Its unique beauty defines our Southern California landscape. At the landfill’s oak tree nursery (above), trees are grown from thousands of acorns that have been collected on-site. Through the replacement oak-planting program, thousands of mature oaks now line the slopes surrounding the landfill. These magnificent trees add beauty to the surrounding neighborhoods, and provide a valuable food source and protective cover for area wildlife. Many of the surplus oak trees have found their way into interesting local projects such as civic re-vegetation efforts. WE’RE A LEAN, CLEAN RECYCLING MACHINE! It may sound funny, but there’s a lot of good that comes from garbage. Landfill gases are converted to clean burning fuels and power is generated. Valuable materials are recovered, saving precious natural resources and conserving landfill capacity. And another good thing: as landfills close, new parkland and recreational areas are created for communities to enjoy. The Puente Hills Landfill actively promotes reuse and recycling through innovative materials recovery programs and a buy-back recycling center. These programs help over 60 cities meet the ambitious recycling requirements set by the California Integrated Waste Management Act (AB 939). The following are just some of ways the Sanitation Districts are helping Los Angeles County area residents and businesses clean up their act. LANDFILL RECYCLING PROGRAMS • Green Waste Recycling – It’s only natural. Waste from gardening, one of the largest single waste types in Los Angeles County, is processed and recycled at the landfill as alternative daily cover and mulch. • Asphalt and Treated Ash Recycling – Paving the way. Asphalt waste from road construction, along with treated ash from the two refuse-to-energy facilities, is used at the landfill to build roads and disposal areas used during the rainy season. • Clean Dirt Recycling – Dishing the dirt. Clean dirt is accepted at the landfill free of charge, and is used on-site for construction and daily cover operations. • Refrigerant, Appliance & Metal Recycling – A cool idea. Refrigerants are extracted from refrigerators and air conditioners and recycled. The remaining metal from these and other appliances, as well as a wide range of other sources, is sold to scrap salvagers. • Wood Palettes Recycling – Knot a bad idea. Wood palettes are sorted and sold back to local businesses. Palettes not purchased are broken down and recycled. CALIFORNIA CERTIFIED BUY-BACK CENTER • The Puente Hills Recycle Center pays for clean glass, paper, aluminum, and plastics. RECYCLING & COMPOSTING: THERE’S A LOT YOU CAN DO! HELP OTHERS. Donate used clothing, toys and household goods to charitable organizations or homeless shelters. Turn worn-out clothes into rags for household cleaning. Use glass or ceramic disposable plates. dishes instead of HELPFUL TIPS. Use both sides for writing or printing. Buy in bulk when possible to eliminate waste and save money. Donate magazines to friends, senior citizens, doctor’s offices, or hospital waiting rooms. AVOID BUYING OVER-PACKAGED PRODUCTS. If you feel a product has too much packaging, contact the manufacturer and explain your concern. Use colorful newspaper or magazines pages as gift wrap. Use shopping bags to line garbage bins or return them to participating stores for recycling. Aerosol cans are not recyclable. Buy products such as hair spray or room freshener in pump spray bottles that are recyclable. Think ahead. Purchase products that are compatible with your neighborhood recycling program. Buy milk in plastic jugs or glass bottles rather than in wax-coated cartons, which are not recyclable. Buy liquid soap, shampoo, and conditioner in refillable sizes. Buy household and commercial cleaning products in refillable sizes. FROM THE KITCHEN: Compost your eggs shells, coffee grounds, tea bags, fruit and vegetable scraps, and corn husks. IN THE YARD: Compost your grass clippings, leaves, shrub and tree waste, sawdust and wood chips. ENERGY RECOVERY ENERGY MANAGEMENT: TURNING SOLID WASTE INTO SOLID RESOURCES. The Sanitation Districts are internationally recognized leaders in the recovery of usable resources.The management of a natural landfill by-product is no exception. Municipal solid waste contains organic materials that produce gas when covered in the landfill. At the Puente Hills Landfill, the Sanitation Districts collect the landfill gas and convert it to an environmentally clean source of electricity. This represents a significant contribution to the community by offsetting needs for non-renewable energy sources and helps to control green house gases involved in global climate change. PUTTING RECOVERED RESOURCES TO WORK. At the Puente Hills Landfill Gas-to-Energy Facility, the methane rich recovered landfill gas is burned in a boiler, creating steam that turns a turbine to generate 50 megawatts of electricity, enough to power about 70,000 Southern California homes. The Gas-to-Energy Facility generates electricity with significantly lower air emissions than a conventional utility power plant, and is one of the largest and cleanest burning facilities of its kind in the world. Landfill gas internal combustion engines generate additional electricity for use at the landfill and the nearby San Jose Creek Water Reclamation Plant. “MEGA” INFRASTRUCTURE. A system of trenches, collection pipes, and wells is engineered into the landfill and continuously incorporated as new cells are laid down. There are currently more than 1,350 wells, 95 miles of underground trenches, and 34 miles of collection pipes in use. Capturing the landfill gas controls odors and other hazards, and prevents escaping gas from contributing to local smog and global climate change. Puente Hills Landfill Gas-to-Energy Facility TRACKING THE FUTURE OF SOLID WASTE MANAGEMENT. The Sanitation Districts are at the forefront of engineering unique solutions to tough problems. One very real problem is siting new solid waste disposal facilities near urban areas. In 2013, the Puente Hills Landfill will close. To solve the projected shortfall in local disposal capacity, an exciting new program is being implemented. It’s called “Waste-By Rail,” and just as the name suggests, the program will provide rail transport of waste to distant disposal facilities to ensure long-term disposal capacity. The local components of Waste-by-Rail are the MRF/Transfer Stations and Intermodal Rail Yards. Take a look at how the system works. MEET MRF: THE PUENTE HILLS “MATERIALS RECOVERY FACILITY (MRF).” The MRF (pronounced “murf”) is the starting point of the Waste-By-Rail system. It began operations in the summer of 2005 and is permitted to manage 4,000 tons of waste each day. The process begins when refuse collection trucks deliver their loads to the MRF station. Recyclable materials are recovered from the incoming waste stream with automated and manual sorting systems. The stream is continually inspected for the presence of hazardous waste or other unacceptable materials. The residual waste will be loaded into sealed intermodal containers that look identical to standard freight shipping containers. GOING INTERMODAL. The filled intermodal containers will be loaded onto trucks at the Puente Hills MRF and taken to the “local rail yard,” located just across the street from the MRF. A tunnel constructed for truck access will eliminate any impact on local traffic. The trucks will make the short return trip with empty containers, ready to be loaded again. LOCAL INTERMODAL RAIL YARD: The outbound full containers delivered to the local rail yard from the MRF will be loaded onto rail cars using overhead cranes. Returning empty containers will be removed from the rail cars and loaded back onto trucks to be transported back to the MRF. REMOTE INTERMODAL RAIL YARD: This facility will transfer full containers from the train to trucks for transport to an adjacent remote landfill. Empty containers will be placed on the train for the return trip to the local rail yard. WASTE-BY-RAIL LANDFILLS. Within Southern California, there are two landfill projects that have proposed to receive waste via rail. They are “Mesquite Regional Landfill” in Imperial County and “Eagle Mountain Landfill” in Riverside County. Both are located approximately 200 miles east of Los Angeles along the Union Pacific Railroad. In 2002, the Sanitation Districts acquired the Mesquite Regional Landfill project and are in development of that facility. The capacity of both of these remote disposal sites could serve the needs of Los Angeles County for the next 100 years—a valuable next step in the future of environmentally safe solid waste collection. The MRF’s environmentally friendly design includes high efficiency air conditioning and lighting, over 500 skylights, reclaimed water for site irrigation and employee restrooms, and high-tech dust, litter and odor control features, including high-speed access doors. Recycled materials were used throughout the project, from structural and reinforcing steel to ceiling and floor tiles. SORTING THINGS OUT. The clean commercial refuse is first inspected for hazardous or unacceptable waste. Then the material is sent to the “sorting floor” where valuable, bulky recyclables such as palettes, wood, metal, carpet, and large pieces of cardboard are separated out. Other waste is sent via conveyor to an automated picking system and finally to the “picking line,” where workers manually sort and grade glass, cardboard, paper, aluminum and plastic (photo above). The recycled materials are then bailed and made ready for sale to industry. The MRF is capable of sorting out virtually any class of recyclables, making it possible to accommodate future markets as they emerge. Entrance gates to Hacienda Hills Trail Head THE HABITAT AUTHORITY: CREATING WIDE OPEN SPACES The population of Los Angeles County is growing at unprecedented rates. As a result, open space for recreation and wildlife habitat is quickly disappearing in this densely developed area. The Puente Hills Landfill Native Habitat Preservation Authority (Habitat Authority) is rising to this enormous challenge by acquiring, preserving, and managing native open space around the landfill. Created in January 1994 by the Sanitation Districts, the County of Los Angeles, and the City of Whittier, the Habitat Authority is recognized for its commitment to creating and maintaining beautiful, wide open spaces for area residents to enjoy. $1 GOES A LONG WAY. When waste is disposed at the landfill, $1 is collected for each ton and set aside for the Habitat Authority. The Habitat Authority currently owns over 1,800 acres of critical open space habitat and wildlife corridor property within the Puente Hills. This is an area more than twice as large as the entire fill area. Including this acreage, the Habitat Authority manages a total of almost 4,000 acres of open space. HAPPY TRAILS TO ALL. In addition to the off-site preservation program, on-site public horseback riding and nature trails traverse the Puente Hills Landfill, but are separated from daily landfill operations. These trails are maintained as part of a regional trail system of the Los Angeles County Department of Parks and Recreation. Saddle up and wind your way through 225 acres of the most valuable native habitat in the southern portion of the landfill. Happily, these canyons have been permanently set aside for preservation. PLANNING THE FUTURE. The Puente Hills Landfill will close in November 2013. Thereafter, major portions of the site will be turned over to the Los Angeles County Department of Parks and Recreation for development as a recreational facility, a great benefit for residents of surrounding communities. And another great benefit… for years to come the methane gas produced in the landfill will continue to be converted into the valuable byproducts of electricity and clean burning vehicle fuels. MEETING The Sanitation Districts provide environmentally sound, cost-effective solid waste management, and in the process, convert waste into resources such as energy and recycled materials. The management of solid waste generated by an urban society as large as Los Angeles County is an enormous challenge, one that will grow even larger given the area’s rapidly increasing population. The Puente Hills Landfill continues to rise to this challenge, creating new technologies and programs that meet today’s needs and offers tomorrow’s solutions. This responsive and progressive management technique is absolutely essential to the future health, welfare and prosperity of Los Angeles County residents. REMEMBER! REDUCE. REUSE. RECYCLE. Every individual can make a significant contribution in reducing the amount of solid waste generated.

Trash and recyclables Once loaded into these trucks, are separated along they are sold and sent the conveyor belt. to make new products Some piles are presorted like a water bowl for me! on the floor too. Much of this work is done by hand. The stuff that is not recyclable (waste) is pushed into pits where trucks with containers are waiting underneath to be filled. Once full, the containers are hauled to a landfill either by truck or train. INTO Wouldn’t it be nice if your trash could go to a place where it could be separated into recyclable materials? Now it can at the new state-of-the-art Puente Hills Materials Recovery Facility or MRF (pronounced “murf”). A MRF is a facility that processes trash and recovers recyclable materials, such as paper, plastic and metal. The recyclables are used to make new products and the waste is disposed at landfills using Hi, I’m Murf the Recycler, and I am here to show you how the Puente Hills MRF works. trucks or trains. The process works with the help of machinery, organization and people. Check out the process in this illustration. You can see that it takes a lot of work to make sure we are recycling as much as possible. Remember, you can do your part by recycling at home, or even better, use products that are reusable and avoid making waste.
