The Department of Environmental Protection on Wednesday rejected a controversial application for a Bucks County hazardous waste treatment facility because the business failed to demonstrate compliance with flood-hazard regulations.

DEP said it denied Elcon Recycling Services' siting application for a proposed liquid hazardous waste treatment facility in the Keystone Industrial Port Complex in Falls Township, the former United States Steel Fairless Works site.

The agency said that Elcon had not complied with its request to provide a hydrologic analysis, including any historical data, to demonstrate that the proposed site has not been flooded in the past.

Elcon's application for the facility, which would treat liquid waste from the chemical and pharmaceutical industry, was opposed by environmental groups such as the Delaware Riverkeeper, the Clean Air Council and the League of Women Voters.
