EPA enforcement on biosolids rules sparks discussion among Colorado landfill operators

Custer County officials are grappling with complex regulations surrounding the application of biosolids, following a special meeting held on March 27, 2025. The discussions centered on compliance with federal guidelines, particularly the Clean Water Act and its 503 rules, which dictate how biosolids can be applied to land.

During the meeting, concerns were raised about the apparent contradictions in federal regulations and local practices. One participant questioned how the county could ensure compliance when federal rules seem to conflict with local operations. The representatives from the biosolid management industry emphasized their adherence to both state and federal laws, asserting that their operations have been compliant for over 30 years.

A significant point of contention was the availability of recent testing results for biosolid contamination levels. Some attendees expressed frustration that the county commissioners did not have access to the latest test results, which indicated lower contamination levels than previously reported. This lack of transparency raised questions about the decision-making process and the information available to local officials.

The meeting also touched on the potential for alternative disposal methods for biosolids, with suggestions for utilizing specific landfill sites that could safely handle the material without contaminating groundwater. Experts noted that the geological composition of certain areas in Custer County, characterized by layers of volcanic ash and clay, could serve as effective barriers against leaching.

As the meeting concluded, officials acknowledged the need for further discussions and clarity on the regulations governing biosolid application. The outcomes of this meeting are expected to influence future policies and practices regarding waste management in Custer County, highlighting the ongoing challenges of balancing environmental safety with regulatory compliance.
