_15_ The applicant has provided a qualitative analysis of the surface water environment. quantitative data on stream flow and stream water quality or a detailed surface water monitoring plan has not been submitted. The amended mining plan delineates a 500 foot buffer zone around the Maitland Arroyo and the unnamed tributary to the Maitland Arroyo. These buffer zones will remain until adequate surface water quantity and quality data has been submitted to the Division. For this reason the following stipulation is required: Stipulation No. 1 THE PERMITTEE SHALL ESTABLISH A TOTAL OF FIVE SURFACE WATER MONITORING STNTIONS NT THE MINIIVG SITE. THESE SHOULD BE LOCNTED AT THE FOLLOWING POIfVTS: UPSTRENM OF THE MINING OPERATION ON THE i~IAITLAND AND GORUON ARROYOS ANU THE UNNAMED TRIBUTNRY OF THE MP,ITLHND NRROYO AND DOWNSTREHM OF THE MINING UPERATiUN ON THE MAITLAND ANU GORDON NRROYOS. THESE FIVE STATIONS SHALL EACH BE MONITORED IN THE FOLLOWING MANNER: 1) A DAILY RECORD OF THE OCCURRENCE OF FLOWS IN ALL STREAM DRAINAGES (e. g. WAS THERE ANY FLOW?); 2) A DAILY DEPTH OF WATER READING; 3) A WEEKLY MEASUREMENT OF PEAK FLOWS; 4) MONTHLY FIELD MEASUREMENTS OF pH, ELECTRO-CONDUCTIVITY, AND TEMPERATURE DURIIVG N PERIOD OF SNOWMELT AND/OR DURING THE FIRST PRECIPITATION EVENT OCCURRING IN THE MONTH; AND 5) A MINIMUM OF THREE WATER gUALITY SAMPLES FOR EACH OF THE STATIONS SHALL BE COLLECTED ANNUALLY. ONE SHALL BE COLLECTED DURING SNOWMELT, ONE DURING N PRECIPITATION EVENT IN MIDSUMMER, AND ONE DURING A PRECIPITATION EVENT AT THE END OF SUMMER. FIELD PARAMETERS OF pH, ELECTRO-CONDUCTIVITY, TEMPERATURE, AND FLOW SHALL BE THKEN PRIOR TU SAMPLING AS DESCRIBED ABOVE. THEN THE SAMPLES MUST BE ANALYZED IN A TIMELY MANWER FUR THE FOLLOWING PARAMETERS (TOTAL ION CONCENTRATIONS IN mg/1): TOTAL DISSOLVED SOLIDS NITRATE-NITRITE TOTAL SUSPENDED SOLIDS PHDSPHNTE UIL AND GREASE ALUMINUM SODIUM ADSORPTION RHTIU ARSENIC CALCIUM BARIUM POTASSIUM COPPER SODIUM IRON BICARBONATE LEAD CARBONNTE MANGANESE CHLORIDE MERCURY SULFATE MOLYBDENUM AMMONIUM SELENIUM FLUORIDE ZINC ALL SAMPLES SHALL BE COLLECTED, PRESERVED, AND ANALYZED ACCORDING TU U.S. E.P.N. METHODS. NLL RESULTS AND DATA COLLECTED FUR THE MONITORING PROGRAM SHALL BE SUBMITTED TU THE DIVISION UN N gUARTERLY BASIS, BEGINNING UN THE 4th MONTH AFTER PERMIT ISSUANCE.
