As an example, successful operation of Coal Creek Station's scrubbers has resulted in SO2 emissions that are less than allowable emissions. Wastewater discharges from Stanton Station were significantly reduced by installing a dry fly ash system in 1995 and by upgrading water-handling technologies. Ash marketing efforts at Coal Creek Station have been underway for several years. The use of fly ash and bottom ash in products reduces the need for the ash to be stored in landfills on the site. Fly ash is mainly used as a cement replacement for making concrete, but has several unique uses including carpet and shingle backing and flowable fill for construction projects.
Bottom ash is used as a gravel replacement, road de-icer and as a bed base for building roads.
Stanton Station's by-products are currently being tested for similar usage. Ash storage ponds at Stanton Station and Coal Creek Station are protected against any potential leaking that could occur into the surrounding natural water systems. The ponds at both sites are dually lined with clay and then a high-density plastic. Coal Creek Station also lines its water evaporation ponds with the same protection. Water samples are tested monthly from area water wells, sloughs and rivers at both facilities to ensure natural water systems are protected .
