HydroAg Environmental LLC collects and recycles pretreatment wastewater industrial food residuals that are of food or organic origin from various processing plants. The residuals may come from sources such as livestock processing, including beef, pork and poultry facilities; food processing facilities; and industrial facilities that produce a beneficial food by-product. These wastewater treated residuals transported from the generation facilities and land applied as soil amendments to farmland across the United States.
Permitting
HydroAg has applied for permits to store and land apply wastewater and wastewater treatment residuals at the following sites. A public comment period is currently underway for the Cassville Storage Tank. The department will hold two public hearings about the draft permit. More information is available in the public comment period link below.
Land Application
On Aug. 28, 2023, HydroAg submitted a wastewater operating permit application for a land application permit and associated Waste Management Plan, which was later replaced with a Land Application Management plan.
- HydroAg Environmental LLC Form A-Application for Nondomestic Permit Under Missouri Clean Water Law, Aug. 28, 2023
- HydroAg Environmental LLC Land Application Management Plan, March 12, 2025
On the basis of preliminary staff review and applying applicable standards and regulations, the department issued a draft operating permit and invited the public to review and offer written comments on the proposed permit conditions until April 21, 2024. However, based on the comments received and the finalization of 10 CSR 20-6.015 rule revision, additional information was requested from the facility. The draft operating permit is being revised. This webpage will be updated when a revised draft operating permit is available for public comment and review.
Cassville Storage Tank
HydroAg is proposing to construct a storage tank facility to provide inclement weather storage for materials licensed for land application during periods of inclement weather, or when land application is otherwise precluded.
