-2- <br />V. Hudroloaic Balance: Surface Water - Rules 2 <br />05.3(4), 7.05.6 (3 ), and 4.05 <br />Surface water information is located on pages 2.04-44 and 2.04-45 of Volume I. <br />Sediment and drainage control plans are presented on pages 2.05-13 through <br />2.05-22, and 4.05-3 through 4.05.7 of Volume 1 of the permit application, <br />and Section V of the Response Volume. <br />The applicant has provided a qualitative analysis of surface water <br />environment. No quantitative data on stream flow and stream water quality <br />has been submitted by the applicant. The applicant has not submitted a <br />detailed surface water monitoring plan. <br />Since the water contained in the old flooded mine workings are toxic, <br />and since this water will be pumped and eventually have to be disposed of, <br />detailed surface water quality and stream flow characteristics are needed <br />in the formulation of a water treatment plan. Inadequate data information <br />is available to determine the impacts of any planned or accidental <br />discharge of water dewatered from Flooded mine workings. The following <br />monitoring frequency and list of field and water quality parameters are <br />stipulated to find the applicant in conformance with Rules <br />Stipulation No. <br />THE APPLICANT SHALL NOT MINE OR CONS'TR UCT SURFACE FACILITIES WITHIN <br />500 FEET OF MAI TLRND ARROYO, GORLI~N ARROYO, AND THE UNIJAMED TRIBUTARY <br />OF MAITLAND ARROYO UNTIL ONE YEAR OF SURFACE WATER QUALITY AND QUANTITY <br />HAS BEEN GATHERED ON THESE DRAINAGES. <br />Stipulation No. <br />THE APPLICANT SHALL NAVE FIELD MONITORING AND SAMPLING EQUIPMENT ON- <br />SITE ALONG WITH A PERSON TRAINED ZN THE COLLETING OF FIELD DATA AND <br />OF WATER QUALITY SAMPLES. <br />Stipulation No. <br />THE APPLICANT SHALL INSTALL, MAINTAIN AND MONITOR SURFACE WATER <br />MONI~RING STATIONS UPSTREAFI AND DOFJNSTR EAM OF THE MINING OPERATION <br />ON THE FOLLOWING DRAINAGES; iIA ITLAND ARROYO, CORDON ARRO}'O, AND THE <br />UNNAMED TRIBUTARY OF /fA ITLAND ARROYO. <br />
