City Council Considers Stricter Odor Rules Following JBS Complaints

The Marshalltown, Iowa, City Council directed staff to draft stricter odor regulations following complaints associated with the city’s JBS meat processing plant.

According to local reports, the council voted 4-3 during its Monday meeting to pursue a separate ordinance chapter addressing odor emissions, as officials discussed whether to take more aggressive enforcement action against JBS, the city’s largest employer.

Assistant Housing and Community Development Director Clayton Ender said all odor complaints received by the city in September were associated with JBS, although he cautioned that the company might not be the sole source of complaints over a longer period.

Water Pollution Control Plant Superintendent Bob Ranson said the city typically receives eight to 15 complaints involving JBS each month, with the frequency varying by season and weather conditions. Nearly 3,000 odor complaints have been recorded since 1999.

Despite the complaints, officials said the city has never fined JBS for odor violations. The existing ordinance allows fines of up to $750 for a first offense and $1,000 for subsequent violations.

Council member Mark Mitchell questioned why the Marshalltown plant continued to generate complaints when a similar JBS operation in Ottumwa reportedly had not experienced the same issues.

City officials said they have historically addressed odor complaints through communication with JBS management rather than citations. Ranson meets monthly with company representatives to discuss complaints, equipment maintenance and potential causes of odors.

City Administrator Carol Webb said the city would consult with its attorney about whether sufficient evidence existed to issue citations under the current ordinance.

Some council members raised concerns about the difficulty of identifying odor sources and gathering evidence sufficient to support enforcement in court.
