Skyline Landfill

Site security is ensured by controlled, limited access to the facility as well as perimeter fencing and electronic surveillance. The facility can only be accessed via a single gate, which directs all traffic to a gatehouse occupied during business hours by trained personnel. During non-business hours the gate is locked and monitored by electronic surveillance.

The Skyline RDF is a Type I Municipal Solid Waste (MSW) landfill. T he site fully complies with U.S. Environmental Protection Agency (EPA) and Texas Commission of Environmental Quality (TCEQ) regulations for municipal and solid waste landfills. The facility employs a multi-layer composite liner system that includes an engineered clay barrier and a 60-mil high-density polyethylene (HDPE) membrane to contain the waste deposited in it and to manage both leachate and the landfill gas naturally produced by decomposition inside the waste mass.

The leachate collection system consists of a permeable layer of engineered materials and piping just above the bottom portion of the liner designed to collect and drain fluids from the landfill; above this is a two-foot layer of soil that protects the liner and system. The collected leachate is pumped into a holding pond where devices circulate and aerate the leachate to prevent odors. As needed, excess leachate is transported to a TCEQ-approved treatment facility.

WM safeguards groundwater in the area by regularly sampling and analyzing water from groundwater monitoring wells on the landfill. To protect surface water, the site manages stormwater runoff using silt fences, rock dams, erosion control mats, and other best management practices.

Skyline RDF collects and manages landfill gas through a sophisticated system that collects the gas generated by decomposition, reduces emissions, flare off low quality and excess gas, and prevents odor. The system collects landfill gas through approximately 237 wells.
