No-Discharge Land Application Enforcement Discretion

On June 30, 2023, the department issued a statement to a select list of entities previously authorized to land apply certain sludges, biosolids and other process wastes without a permit according to 10 CSR 20-6.015(3)(B)8. Due to a recent decision by the Missouri Fertilizer Control Board, these companies and businesses will no longer be exempt from department permitting requirements. The letter stated the department’s intent to exercise enforcement discretion for entities performing the continued land application of material formerly licensed as fertilizer, as long as the entity adhered to the minimum operational parameters and conditions set by the department in that letter, including the condition that the entity apply for an operating permit. The department's letter, along with an excel file containing a list of individual materials land applied, their source facilities and the associated entities authorized for land application of those materials is available below.

The department drafted the June 2023 letter to expire at the end of 2023, anticipating that permits would have been able to be issued before the end of the year. On Dec. 29, 2023, the department issued letters to the following facilities, stating the department will continue exercising its enforcement discretion to withhold pursuing formal enforcement action and penalties until their permit can be issued.

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 proposes 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 has 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.

Roy Blunt Reservoir

On Nov. 17, 2023, the North Central Missouri Regional Water Commission submitted a request to the department for Clean Water Act Section 401 Water Quality Certification for the Roy Blunt Reservoir. The proposed multi-purpose, 2,328-acre reservoir will be located in Locust Creek and wetlands next to unnamed tributaries to East Fork Locust Creek, in Sullivan County, Missouri. The proposed project is estimated to impact approximately 400 acres of wetland and 50 miles of stream. The department invited the public to review and submit written comments on a draft certification for the proposal during a 30-day public comment, originally from Dec. 20, 2023 to Jan. 19, 2024, but later extended to Feb. 9, 2024. 

The department issued a final 401 Water Quality Certification to the North Central Missouri Regional Water Commission on Feb. 23, 2024.
