The RCRA, passed in 1976, focuses on preventing the release of hazardous wastes into the environment by providing for their management from generation to disposal. Most mining, milling, and smelting solid wastes, like those discussed in this booklet, are "high-volume, low-hazard" materials that have been exempt from regulation under RCRA.
