Simco Road Regional Landfill is one of Idaho's largest waste disposal options. Our environmentally superior, cost efficient, technologically advanced and professionally managed site is a model of Landfill excellence, and our advocates include Elmore County, Idaho, Idaho DEQ, Elmore County Health Dept., Idaho EPA and the Idaho Dept. of Agriculture. We are proud of our spotless record and reputation for running the premier Subtitle D landfill operation in the region. We have the location, technology and efficiency to accept waste streams from the largest project to the smallest project.

Simco Road Regional Landfill has a permitted capacity of 210 million tons of air space, with initiatives in place to double our size by end of year 2005. We are connected to customers by truck, barge network of the Columbia River, and by the transportation system of the Union Pacific Railroad and its interline connections.

The landfill is permitted to accept residential, commercial, industrial and special waste streams including municipal solid waste, construction and demolition debris, wood wastes and petroleum contaminated soils. We offer two solidification pits and accept drum waste fitting Subtitle D criteria for solidification. We do not accept hazardous waste or dangerous waste.

The Simco Road Regional Landfill (The Landfill) uses the most advanced design and technology available to protect the environment, far exceeding Federal Subtitle D standards. Ongoing investment and innovation by its developers, along with the site’s unique hydrogeological features, easy access and remote location make it one of the most secure facilities in the country. The Landfill, permitted in 1999, is located in the arid region of southwest Idaho, which experiences less than six inches of annual precipitation. The site is atop an alluvial plain that contains a 350-foot thick layer of basalt. A clay and silty-clay layer overlies the basalt layer with an average thickness of 67 feet. The regional aquifer is more than 450 feet below the ground surface. The site currently accepts waste from 5 states, is rail capable for up to 100 rail cars in a single event, and is currently permitted to 210 million tons, with expansion to 420 million tons planned in the next 12 - 18 months. The Landfill is Bovine Spongiform Encephalopathy approved.
