Summary The Review Process The Twin Pines No. 2 Mine is in permanent cessation, and the operator has initiated preliminary reclamation activities. The mine is owned by Twin Pines Investment Limited. A permit to operate the mine was originally issued on December 17, 1984. The permit was renewed and reissued on April 30, 1990. This application constitutes the second renewal and is for reclamation activities only. The mine ceased operations on August 31, 1993. Pursuant to Rule 2.08.5, on March 3, 1994, the Division notified Twin Pines Investment Limited of the need to renew the permit in a timely manner. The Division received the renewal application on September 1, 1994. The application was deemed incomplete and the operator was notified in a letter dated September 9, 1994 of the incomplete status. The application was resubmitted on October 26, 1994 and was deemed complete on October 28, 1994. Due to the delay of the application submittal and completeness, the adequacy review of Technical Revision No. 7 was substituted for the permit renewal adequacy review. The TR-07 adequacy review includes all outstanding issues. The operator was notified of this decision in a letter from the Division dated December 6, 1994, and TR-07 was conditionally approved on February 1, 1995. Stipulation No. 17, attached to the approval, was terminated on March 9, 1995. Final approval of the permit renewal, with conditions, occurred on March 31, 1995.
