Jefferson Countys Board of Representatives is considering the purchase of a site for a new sanitary landfill. The purchase price for the site is $280,000 and preparatory work will cost $70,265. The landfill would be usable for 10 years. The board hired a consultant, who estimated that the new landfill would cost the county $57,000 per year less to operate than the countys current landfill.
