Document Description
The project is to permanently close an abandoned mine within the boundaries of the Antelope Valley Indian Museum State Historic Park. The abandoned mine is a simple mine with one large adit and one very small horizontal adit. It's estimated that there is at least 150 feet of underground workings. The main portal has extensive creep debris and rock slippage from the surrounding hillside. In 2009 in conjunction with the Department of Conservation Abandoned Mines Lands Unit a complete inventory of abandoned mines was completed for antelope Valley Indian Museum State Historic Park. As part of this inventory process, a remediation work plan was developed to identify and prioritize these abandoned mines and features for closure with the Park. The project is to remove the rocks and debris from the portal and install a bat / wildlife friendly gate, which will be installed onsite and anchored into the rock. The bat / wildlife friendly gate will be a standard design angle-iron bat gate (with a removable steel bar with McGard bolt), set approximately 5 feet inside the adit portal. A small backhoe will be needed to pull and remove rocks and debris from the portal, to allow access to the main adit, which is needed to permanently secure the bat / wildlife friendly gate in place. DPR-approved standard project requirements have been incorporated into this project. A copy of these requirements may be obtained by submitting a request to the project Environmental Coordinator listed below.
