Pacific faces rising wastewater ammonia limits; staff outline possible $10–17 million treatment need and short-term options
Summary
City staff told aldermen federal and state ammonia limits will tighten; engineers estimate a full ammonia-removal project could cost roughly $10—$17 million, and the city is pursuing lower-cost contractor proposals (sludge removal plus biological treatments) that staff say might be structured with performance guarantees.
Public works staff warned aldermen that the city's lagoon-based wastewater system will face new ammonia permit limits that the existing configuration likely cannot meet. Engineers and the public works commissioner said a full conventional treatment upgrade could be in the multiple millions; the engineering estimate shared in the meeting was roughly $10—$17 million for a treatment system that would reliably meet new ammonia and phosphorus limits.
The public works commissioner described an alternative approach offered by a private contractor: remove accumulated sludge, deploy proprietary biological treatments and provide a performance guarantee. The vendor's approach would require a pilot or demonstration, the staff said, and legal review of any "no-pay-unless-it-works" guarantee before the city commits funds. Staff said they planned to seek quotes and ask the city attorney to vet proposed contract terms.
Because budget timing is tight, staff proposed reducing a large, placeholder treatment line in the draft budget to a smaller maintenance amount to keep the budget from ballooning while the city secures firm quotes. The board agreed to reduce the lagoon maintenance/treatment contingency to $10,000 (from the previously discussed $80,000–$165,000 figure) while staff pursue bids and legal review.
Why it matters: failing to meet ammonia permit limits can trigger enforcement by Missouri Department of Natural Resources and U.S. EPA, including fines, permit restrictions or consent-decree obligations. Staff framed the contractor proposal as a potentially lower-cost, interim strategy to avoid immediate, large capital borrowing.
What's next: staff will seek written proposals, compare multiple engineering options and return to the board with vetted costs and legal analysis before any substantial budget amendment or contract award.
