How much waste is accepted daily?
The facility accepts approximately 3,700 tons of waste daily.
Where does the waste originate?
The waste disposed of at Middle Point is generated at homes and businesses from 34 counties throughout Middle Tennessee, including Murfreesboro and Rutherford County.
What types of wastes are accepted at the landfill?
Nonhazardous solid waste from residential and commercial establishments (municipal solid waste) is accepted, as are industrial wastes and construction and demolition materials. All hazardous and liquid wastes are prohibited from disposal at Middle Point, as are many other waste types, including untreated medical waste, car batteries and whole tires. Republic has developed an extensive waste plan that outlines procedures to ensure prohibited waste is not brought into the landfill. Middle Point no longer accepts Bulk Survey for Release program materials.
What environmental protection systems are in place?
Middle Point is operated in a manner that protects public health and the environment. We work closely with the Tennessee Department of Environment and Conservation to ensure that we meet or exceed all state and federal regulations. All waste is disposed of within the boundary of a constructed landfill area that has been engineered to protect the environment and meets all federal, state and local regulations. There are many environmental protection systems at Middle Point, including but not limited to the following:
Landfill liner: The liner at the base of the landfill consists of five feet of compacted clay geologic buffer, two feet of compacted clay liner, a high-density polyethylene liner, a geocomposite drainage layer, gravel drainage corridors and one foot of protective cover. In total, there are seven feet of compacted clay and a plastic liner between the waste and the natural environment. All of the liners are thoroughly tested to meet regulations and ensure proper engineering construction standards.
Leachate collection: The system to collect liquid within the landfill includes perforated pipes placed above the liner system to collect any liquid that has touched waste. The liquid is then processed through our state-of-the-art Membrane Biological Reactor pretreatment plant and discharged to a wastewater treatment plant for final processing.
Rainwater collection: Rainwater that does not touch any waste must also be managed appropriately. Stormwater runoff is collected and contained in retention ponds, allowing soil particles to settle before the water is discharged to a nearby waterway. Visual inspections are conducted regularly, and analysis and samples is done annually by a third party professional engineering company.
Groundwater monitoring: Wells have been placed around the site perimeter to ensure that landfill operations are not impacting groundwater. Five wells and two springs are sampled semi-annually, and results are submitted to the state.
Gas collection: Once trash is disposed of, it naturally decomposes and produces gas. A landfill gas management system collects gas through a series of pipes and more than 250 gas wells. The system is regularly monitored to minimize odors and prevent gas migration.
Final capping: Once we bring the waste to permitted final elevation, we place a final cover over the top to entomb the waste. This cover keeps liquids out and gases in and ensures protection of the environment. The cap includes 18 inches of clay soil, a polyethylene liner, a geocomposite drainage layer, and 18 inches of topsoil and vegetation.
Who permits and inspects the facility?
The facility is fully permitted and inspected by the Tennessee Department of Environment and Conservation each month, or more often.
What does Middle Point Landfill mean to the community?
Rutherford County has a population of more than 280,000 individuals who generate household waste on a daily basis. The trash needs an outlet, and a landfill in Rutherford County ensures adequate competition among waste service companies. For the residents of Rutherford County, the existing host agreement translates to no-cost disposal services. Counties that do not have landfills typically pay higher rates for waste services.
Middle Point Landfill is an integral part of the local economy. It provides jobs for local residents and affordable waste disposal options for residents and businesses. We also support the local economy with the purchase of goods and services. Financial support has also been provided to the local schools, municipalities, Rutherford County projects and foundations, and other important local interests and endeavors.
In addition, Murfreesboro and Rutherford County receive host community benefits and fees. In 1995, Rutherford County and BFI entered into an agreement for Middle Point that allowed the county to send its household waste to the landfill free. Later that year, the City of Murfreesboro entered into an agreement with BFI for its residents to benefit from no-cost trash disposal (216k tons, worth approximately $6.7 million in 2017). This all equates to jobs and much-needed revenue for local and state economies.
What additional steps are taken to ensure that the landfill is a good neighbor?
Proper daily operations are critical to environmentally sound waste disposal. Therefore, all employees at Middle Point are trained to handle incoming waste in the most environmentally responsible manner. Access to the site is limited to one entrance/exit. The facility records and tracks all waste shipments with gate receipts and a network of video cameras. Each load of incoming waste is visually inspected to ensure that only permitted materials are accepted for disposal. Once unloaded, the waste is visually inspected again. At the end of each working day, daily cover is placed over the waste. Steps are also taken to control dust, litter and odor. Periodic watering of access roads prevents dust from rising when trucks travel in and out of the landfill. A sweeper is used to keep nearby roadways clean. Litter is minimized by limiting the size of the active disposal area, applying daily cover and using fencing on windy days to catch blowing materials. Any litter that blows off-site is collected by landfill personnel.
How do you control odors?
Landfill gas and odors are controlled with good operational programs such as waste compaction, applying daily cover per our permit, and the use of an effective landfill gas collection and control system. Landfill personnel conduct routine odor inspections to minimize and deal with odor as quickly as possible once detected. The landfill gas system is upgraded and expanded on a regular basis as the landfill grows. We install gas collection infrastructure much earlier than required by federal and state regulations. Additionally, we use a misting/odor-neutralization system to assist with odor control. Any odor reports can be made directly to the landfill by calling the landfill manager at (615) 896-2075.
What is the life expectancy of the landfill?
The life expectancy varies depending on the volume of waste received for disposal. There is capacity for approximately 8 to 9 years of disposal at current disposal rates.
It appears that there is construction going on at the landfill. What’s happening?
It is common to see construction activities at the landfill that may include the use of heavy equipment. This construction is part of the ongoing operation and maintenance of our environmental protection systems.
When is the landfill open for business?
Middle Point is open Monday through Friday from 5:00am to 4:00pm and Saturday from 7:00am to 11:00am. Middle Point is closed on Sundays and major holidays.
Can I take a tour of the landfill?
As it is a working landfill, the safety of the public and our staff is top priority. For safety and security reasons, we no longer offer public tours of Middle Point Landfill.
