The design standards for SKB Rosemount exceed Federal Subtitle D standards. Each cell at the facility is lined with a tertiary liner system. The primary 80 mil HDPE liner, underlain by a 60 mil HDPE secondary liner, underlain by a tertiary liner consisting of clay and Claymax ®.

The design incorporates two leachate collection systems with all leachate being treated at a wastewater treatment plant adjoining the site. In the unlikely event of a leak in the primary liner, the dual liner system allows for immediate detection, collection of leachate, and repair of the liner without risking environmental health.

An extensive network of groundwater monitoring wells is regularly sampled to test up and down gradient water quality.
