(Calais)has received the February 12,2020 Notice of Compliance Problems with <br /> Required Corrective Actions. Two problems were presented in the Notice,failure to file a Succession of <br /> Operators within 30 days and a failure to minimize disturbances to the prevailing hydrologic balance. A <br /> time frame of 60 days was given for corrective action,with a Succession of Operators application and a <br /> Technical Revision addressing Idaho Tunnel water management at the Cross Mine both due on April 12, <br /> 2020. Since that time,efforts to reduce the spread of Corona Virus have resulted in limitations on <br /> gathering size and closures of schools,offices,and restaurants. While Calais continues to make progress <br /> on the Notice of Compliance,an extension of 90 days is requested to accommodate the substantial <br /> disruption to normal business practices caused by the Corona Virus. <br /> In terms of progress made thus far,Calais has: <br /> • Begun the paperwork to unify the company name among permitting agencies(including financial <br /> warranty forms,legal right of entry,and structure agreements) to support the Succession of <br /> Operators agreement. <br /> • Reconnected the previously Idaho Tunnel drainage on January 29,2020 to the water treatment <br /> system,resulting in substantial water quality improvement at the Industrial Wastewater outfall. <br /> All February testing has produced results below the 30-day average permit limit for all chemical <br /> constituents except for a single potentially dissolved cadmium detection of 2 ug/L,above the 30- <br /> day permit limit of 0.b3 ug/L. Potentially dissolved cadmium was below detection limits in <br /> subsequent analysis. <br />
