The borrow areas are a very important part of the landfill. Every day soil is excavated from these sites for various purposes. Soil is used as a daily cover, intermediate cover, and final cover for garbage in the landfill. Borrow areas also provide soil for the purpose of building the many dirt roads that are associated with the landfill.
A daily cover of soil is spread on the working face of the landfill to hold trash down and keep pests away. An intermediate cover is used on a lift which is an 8 to 10 foot layer of trash. Lifts are small cells separated on all sides by an intermediate layer of soil. The final cover is the layer of soil that goes on top of the landfill when it has reached capacity.
