BMRI must submit the required Shewart-CUSUM charts for a eight (8) <br />performance monitoring wells by Ivlay 26, 2000. The charts must incl de monitoring <br />results for December, 1999 and January, February, March, and Ap 1 2000. The <br />charts will be submitted every month thereafter for previous mont 's monitoring <br />results until the performance monitoring ceases. <br />' Response: <br /> <br /> <br />A brief discussion of the Shewhart-CUSUM results and the associated chart;; for the eight <br />performance monitoring wells aze presented in Attachment B. Subsequent monthly <br />performance monitoring water quality data will be submitted as the data az~ received and <br />analyzed according to the time schedule specified by DMG. <br />' Comment.• <br />1 <br /> <br />4. BMRI must submit an updated map showing the location of the "inte#ceptor" wells, <br />the new point of compliance (M-34), the new injection wells and the piping system <br />for the interceptor wells to the injection wells and the process water system tot he <br />infiltration trench. The map must be submitted to the Division by May ~26, 2000. <br />t Response: <br />II <br /> <br />1 <br /> <br />^, `~'~ ~ <br />A map showing the requested facilities is included as Attachment A. <br />Battle ,4launtain Resources <br />3 <br />i,Niller, lnc. <br />,Liay s, zooo <br />
