UGW470001 PURPOSE OF PUBLIC NOTICE THE UTAH DEPARTMENT OF ENVIRONMENTAL QUALITY IS SOLICITING COMMENTS ON ITS PROPOSAL TO ISSUE A GROUND WATER DISCHARGE PERMIT DESCRIBED BELOW UNDER AUTHORITY OF THE UTAH WATER QUALITY ACT, SECTION 19-5-104(1)(I) UTAH CODE ANNOTATED 1953, AS AMENDED AND UTAH ADMINISTRATIVE CODE R317-6. PERMIT INFORMATION PERMITTEE NAME: SIMPLOT PHOSPHATES LLC MAILING ADDRESS: 9401 NORTH HWY 191 VERNAL, UT 84078-7795 FACILITY LOCATION: 10 MILES NORTH OF VERNAL, UT SIMPLOT PHOSPHATES LLC OPERATES A SURFACE MINE AND CONCENTRATOR FACILITY FOR PROCESSING ORE USED IN THE PRODUCTION OF PHOSPHATE FERTILIZER. PHOSPHATE MINERAL GRAINS ARE SEPARATED FROM THE ORE AND PUMPED IN A SLURRY PIPELINE TO ROCK SPRINGS, WYOMING. CLAY FINES AND BARREN MINERAL GRAINS FROM THE ORE PROCESSING ARE PUMPED TO THE TAILINGS STORAGE FACILITY (TSF). CLARIFIED WATER FROM THE TSF IS RECLAIMED FOR RE-USE IN ORE PROCESSING.

THE TSF IS UNLINED, BUT IT IS LOCATED ON THE OUTCROP OF THE MOENKOPI SHALE, A GEOLOGIC FORMATION WHICH HAS LOW PERMEABILITY AND WHICH CONTAINS GROUND WATER OF NATURALLY POORER QUALITY THAN THE WATER STORED IN THE TSF IMPOUNDMENT. UNDER THE TERMS OF THE GROUND WATER DISCHARGE PERMIT, SIMPLOT PHOSPHATES IS REQUIRED TO MONITOR THE QUALITY OF GROUND AND SURFACE WATER WHICH COULD POTENTIALLY BE AFFECTED BY THE TSF. IF CONTAMINANT CONCENTRATIONS IN MONITORED WELLS AND SURFACE WATER EXCEED PERMIT PROTECTION LIMITS, SIMPLOT PHOSPHATES IS REQUIRED TO INVESTIGATE THE CAUSE OF WATER QUALITY CHANGES AND CORRECT THEM IF THEY ARE DUE TO OPERATION OF THE TSF OR OTHER MINE ACTIVITIES.
