The city has finalized its agreement with a local dairy manufacturer that provides a long-term solution to the firm’s violations of some sewage discharge limits.

Smith Foods Pacific, 20 Midwest Drive, formerly Pacific Valley Dairy, manufactures ice cream mix, frozen dessert products and soft-serve items, which are distributed in Missouri, Illinois, Texas and Florida.

Due to the high milk fat content of the product, the plant has released excessive amounts of biochemical oxygen demand (BOD5), total suspended solids (TSS), and oil and grease (O&G) into the city’s sewer system.

Seeking a permanent solution to the wastewater discharge violations, the city initiated surcharges and penalties for the violations.

Smith Foods paid the charges, but disputed the penalties, which included the city’s legal and engineering costs to evaluate the violations.

In continuing talks between the city and the manufacturer, the city removed the legal and engineering costs, but called for the firm to solve the discharge problems at the plant.

In the recently approved agreement, Smith Foods agrees to construct a pretreatment plant at the Pacific location, with construction starting in July 2018 and being completed and operational by May 31, 2019.

During the planning and construction of the pretreatment facility, the city will continue to sample wastewater discharged from the plant and bill the firm a surcharge for amounts of BOD5, TSS, and grease and oil above the limit.

On Nov. 21, aldermen gave final approval for the mayor to sign the agreement with Smith Foods.
