Mr.Joel Renfro RE: Timnath Connell Pit M-1999-050 April 29, 2025 • All surface areas within the proposed area for release have been vegetated for stabilization as required to control erosion. 3.1.7 Groundwater The operator has complied with applicable groundwater quality standards in effect during mining operations and reclamation activities at the site. 3.1.8 Wildlife The Timnath Connell Pit is not considered prime wildlife habitat. • Mining and reclamation activities did not disturb existing wildlife species that require special consideration on or near the site. • Wildlife habitat creation was not a part of the reclamation plan. 3.1.9 Topsoiling Topsoil has not been removed from the areas not disturbed by mining activities. In areas disturbed by mining activities: • Topsoil was removed, stockpiled, managed, and replaced within the proposed release area. • Following backfilling and prior to revegetation, topsoil was replaced in as even a manner as possible. The topsoil had been removed in preparation for mining, stockpiled on-site, and managed to prevent erosion and sediment transport. 3.1.10 Revegetation The proposed release area has been revegetated with a self-sustaining, native grass seed mix as described in the pre-amendment permit Timnath Connell Pit permit application. Prior to the 2024 permit amendment, maintenance of the requested release area was to encourage the native grass growth, so herbicides have not been used and weed control of the area has been restricted to mowing. The vegetation growth has provided soil stabilization and minimized erosion across the proposed release area. Active maintenance and mechanical weed control is still being performed in the area for perennial weeds (i.e. kochia, Russian thistle). However, significant growth of noxious weeds has not been observed within the area. 3.1.11 Buildings and Structures There are no buildings within the proposed release area. Structures within the proposed release area include some utilities associated with the Weitzel Road utility easement. Other structures include the relocated Box Elder Ditch and associated infrastructure. 3.1.12 Signs and Markers All mining-related signs and markers have been removed from the proposed area for release. As a Timnath Connell Pit representative for Connell Resources, Inc., we are satisfied that the reclamation requirements of the proposed permit release area listed above were met in Page 3 of 4
