Exhibit 1 <br /> including the following: <br /> a. On October 27,2022,CC&V submitted TR-132 to update the ECOSA Monitoring <br /> Plan. In TR-132,CC&V committed to submit a subsequent TR containing a long- <br /> term plan for investigating and mitigating seepage from ECOSA. <br /> b. On June 29, 2023, CC&V submitted TR-138, proposing the installation of <br /> additional wells in Grassy Valley to monitor groundwater quality and intercept and <br /> collect impacted groundwater to prevent it from migrating into lower Grassy <br /> Valley. After a meeting between CC&V and the Division it was determined that <br /> TR-138 did not provide a long-term plan per the TR-132 commitment and TR-138, <br /> as submitted, exceeded the scope of a technical revision. The Division informed <br /> CC&V the intent to deny TR-138 as submitted and CC&V withdrew the <br /> application on July 27, 2023. <br /> c. On December 20, 2023, CC&V submitted TR-141, proposing installation of <br /> monitoring wells as Phase I of a short-term plan for mitigating seepage from <br /> ECOSA. The proposed wells were intended to support additional monitoring of <br /> Grassy Valley and to allow potential conversion to interception wells in the future <br /> for extraction of seepage.The Division approved TR-141 on April 3,2024.CC&V <br /> completed installation of the wells pursuant to TR-141 on August 22, 2024. <br /> d. On May 24,2024,CC&V submitted TR-144,proposing to construct improvements <br /> to the collection system for surface expressions of seepage from ECOSA.TR-144 <br /> was approved by the Division on September 23,2024. <br /> 14. On July 17, 2024, the Division issued a Reason to Believe a Violation Exists and <br /> Notice of Board Hearing letter("Reason to Believe Letter") to CC&V for the following alleged <br /> violations: <br /> a. C.R.S. § 34-32-116(7)(c) and Rule 3.1.5(5) for failure to protect the drainage <br /> system from acid forming or toxic producing materials, <br /> b. Rule 3.1.5(10) for failure to dispose of all mined material within the affected area <br /> in a manner to prevent any unauthorized release of pollutants to the surface drainage <br /> system, <br /> c. Rule 3.1.5(11) for failure to prevent unauthorized release of pollutants to <br /> groundwater from any materials mined, handled or disposed of within the permit <br /> area, <br /> d. C.R.S. § 34-32-116(7)(g)(I)and Rule 3.1.6(l) for failure to minimize disturbances <br /> to the prevailing hydrologic balance of the affected land and of the surrounding <br /> area and to the quality of water in surface and groundwater systems both during <br /> and after the mining operation and during reclamation, and <br /> e. Rule 3.1.7(9) for failure to provide the Office a written report within five (5) <br /> working days when there is evidence of groundwater discharges exceeding <br /> 3 <br />
