American Foods

On April 8, 2022, Woodard & Curran Inc. submitted an Antidegradation Report and applications for a new 3.5 million gallon per day (MGD) facility for American Foods Group, later changed to American Foods Development Co., and Public Water Supply District No. 2, in Wright City, Missouri. American Foods is proposing to process 2,400 cows per day, which contributes 1.5 MGD of the proposed 3.5 MGD. The long-term plan is to incorporate flows from the Wright City South Wastewater Treatment Facility and provide additional treatment capabilities for community growth while accommodating water quality goals. The draft water quality and antidegradation review received significant public comments based on concerns with silt accumulation in Lake St. Louis. The department will address responses to comments made on the draft water quality and antidegradation review in the public notice for the proposed operating permit.

Antidegradation Review

On Dec. 8, 2023, American Foods Development Co. LLC submitted a wastewater operating permit application for a new facility, America’s Heartland Packing Wastewater Treatment Facility, with an update submitted Jan. 16, 2024. This industrial facility is exempt from construction permitting, according to 10 CSR 20-6.010(5)(A)5. On the basis of preliminary staff review and applying applicable standards and regulations, the department issued a draft operating permit for public review and comment. The draft permit contains the conclusions of the antidegradation review and responses to the public’s comments received during the antidegradation review public comment period. The department invites the public to review and offer written comments on the draft permit and scheduled two public hearings an opportunity for the public to provide verbal comments to the department.

The facility is expected to transfer to the district shortly after the industrial permit is issued. The ownership transfer will require another permit public comment period, as some of the conditions will change. There are different regulatory requirements for publicly owned treatment works than there are for industrial dischargers.

HydroAg

On Aug. 28, 2023, HydroAg Environmental LLC submitted a wastewater operating permit application for a new land application permit and associated Waste Management Plan. HydroAg collects and recycles pretreatment wastewater industrial food residuals (IFR) that are of food or organic origin from various industrial food processing plants to be beneficially land applied as organic fertilizers and soil amendments to farmland across the U.S.  IFR may come from sources such as livestock processing including beef, pork and poultry facilities, further food processing facilities, and industrial facilities that produce a beneficial food by-product. 

The department proposes to issue a Missouri State Operating Permit for the HydroAg Environmental LLC, subject to certain effluent limitations, schedules and special conditions. The department invites the public to review and offer written comments on the proposed permit conditions until April 21, 2024. For more information, please review the public notice announcement below.

Missouri Prime Beef

On Aug. 2, 2022, Missouri Prime Beef Packers submitted a wastewater operating permit renewal application, and associated antidegradation application on Nov. 17, 2022. Missouri Prime Beef Packers was requesting permission to conduct slaughter and processing of live cattle for wholesale, as well as storage and discharge of wastewater and land application of sludge as fertilizer to agricultural fields located near the basin location at agronomic rates. The draft water quality and antidegradation review received significant public comments based on concerns with the documentation provided for the innovative technology proposed for treating wastewater before discharge.

On the basis of preliminary staff review and applying applicable standards and regulations, the department proposed to deny the operating permit application and modification request. The department invited the public to review and offer written comments on the proposed action and scheduled several public hearings an opportunity for the public to provide verbal comments to the department. 

On Jan. 2, 2024, the department received notice that Missouri Prime Beef Packers was withdrawing its permit application to use the innovative iLEAF technology for discharge to the Pomme de Terre watershed. As the department no longer had a permit application to consider or deny, the public hearing scheduled for Jan. 6, 2024, was cancelled. No future public meetings for this site are scheduled at this time. 

On Jan 10, 2024, Missouri Prime Beef Packers and the department entered into an Administrative Order on Consent (AOC) to respond to, and resolve, land application and permit-related Missouri Clean Water Law violations. The AOC includes penalties for the land application violations, requirements to submit a permit application, and a legal mechanism establishing temporary operational controls and land application requirements, including ramifications of continued noncompliance (including cessation of land application activities). The AOC does not authorize discharge to Pomme de Terre River or any other waters of the state. Discharge will only be authorized following issuance of a Missouri State Operating Permit that has undergone the permitting and associated stakeholder engagement process. The permit will replace the temporary land application conditions in the AOC. The department will continue to provide assistance to the facility and its engineer to design and construct a wastewater treatment system that meets all applicable regulatory and water quality requirements.
