Residents, commissioners press Wilson County on STEP-system permits and who will be responsible for long-term maintenance

Public comment at the end of the meeting moved from individual agenda items to a broader policy debate about STEP wastewater systems, the county water authority and the recently adopted land-use plan.

Resident Ken (Hank) Young said the water authority was in "substantial noncompliance," citing statutory language (public chapter referenced in the hearing) that a commissioner may not issue a new permit if the permittee is not substantially in compliance. He warned that, if the water authority cannot get a permit modification or a new permit for additional STEP systems, developers may seek to form separate utilities or hire private STEP-system operators — leaving the county with unanswered questions about long-term responsibility, inspection and bonds.

"If the water authority cannot get a permit modification or a new permit for a step system, then how do we go forward?" Young asked. He said the likely result would be developers seeking alternative permit holders and that the county must think through who would be financially responsible if STEP systems fail.

Several commissioners voiced similar concerns during an extended back-and-forth: they said the county requires a signature from an accredited sewer provider on final plats and that permit applicants must show they will maintain systems and supply bonds before lots are sold. Commissioners asked whether the new legislation changed the definition of an accredited utility and what safeguards ensure accountability when private contractors operate STEP systems. One commissioner recalled prior cases where partial or poor construction left the county to correct problems later and urged systems for segregated accounts or perpetual bonds tied to permits.

Staff said final plats require a signature from the sewer provider confirming installation to their specifications and that the provider must have adequate bonds in place before lots are sold. The county planning director said he relies on permit holders and outside agencies (TDEC, Adena/water authority) for technical verification and said staff do not have the in-house capacity to validate every engineering detail on step systems.

The debate closed without formal policy action at the meeting, but commissioners said they expect to revisit the questions of permit-holder responsibilities, bond size and whether the county should require additional documentation or financial assurances before approving developments dependent on STEP systems.

Next steps: Commissioners and staff flagged the need for additional policy work on verification, bonding and long-term maintenance arrangements for STEP systems; the issue was left for future meetings and possible ordinance or practice changes.
