Ground Water Discharge Permit No. UGW010008 is being modified for the continued operation of swine production facilities owned by Mango II-Milford, LLC ('Mango II'). The permitted facilities are located in Beaver County, approximately 22 miles south of Milford, Utah. Manure from the hog production facilities is washed into anaerobic basins for treatment and storage. The permitted facilities at each farm site consist of one primary lagoon and one containment basin for evaporation. In addition to well monitoring, the basins are lined with a flexible membrane liner for the protection of ground water. The ground water quality beneath farm sites ranges from Class 1A Drinking Water Quality to Class III Limited Use Water Quality.
Modification to the Permit
At the request of the Permittee, changes were made to the Permit, including general language changes for consistency across all of Mango II's Ground Water Discharge Permits and changes to the out-of-compliance notification process. The changes proposed in this modification include:
1. Revisions to the probable out-of-compliance and out-of-compliance notification requirements.
2. Adjustments to probable out-of-compliance and out-of-compliance confirmation sampling frequencies.
3. Timeline adjustments for the submission and implementation of Source and Contamination Assessment Study Plans.
4. General language edits throughout the Permit to improve clarity and consistency with Mango II's other Ground Water Discharge Permits near Milford, Utah.
5. Mango II is now required to determine and report the hydraulic gradient and flow direction for each farm system that contains a confirmed out-of-compliance upgradient monitoring well.
