3. Routine safety inspections would be conducted to check the work area for such hazards as <br />loose roofs, dangerous gases, and inadequate ventilation. <br />4. Waste rock piles from mining would be wetted to control dust. <br />5. Water and, if necessary, surfactants would be, used inside the mine workings to control dust <br />from vehicular traffic, and all underground drilling activities use water so that dust from drilling <br />is minimized. <br />6. Split-set roof bolts would be installed at a specified spacing to prevent roof cave-ins, the <br />biggest cause of mining injuries. Brattice builders would construct doors, walls, and partitions in <br />tunnel passageways to force air into the work areas. Shift bosses would oversee all operations at <br />the worksite. <br />7. Gamma surveys would be conducted in the working areas of the mine to ensure that workers <br />are protected from external radiation. - <br />8. Radon within the mine would be measured in accordance with regulations at 43 CFR, Part 57, <br />to ensure worker safety and to control worker exposure to radon and its daughter products. <br />Radon measurements would be used to adjust mine ventilation and the working environment as <br />necessary to ensure that worker exposures do not exceed the annual dose limit for radon a.nd to <br />maintain exposures as low as is reasonably achievable. <br />9. Gamma surveys would be conducted accordance with regulations at 43 CFR, Part 57 within <br />the working areas of the mines in order to monitor the potential external radiation exposure of <br />mine workers. These surveys would provide necessary information to determine (1) time and <br />distance restrictions, if necessary, within particular areas of the mines and (2) the need for <br />personal radiation detection monitoring. <br />10. General worker.safety would be ensured through routine observation of worker behaviors <br />and working areas within the mines and the presence of safety personnel to ensure that MSHA <br />safety requirements are met. In addition, frequent and regularly scheduled safety meetings would <br />be conducted to ensure a very high level of safety training and awareness by mine workers. Such <br />training and indoctrination would be mandatory. <br />11. Mine ventilation systems would be monitored and modified as needed to ensure that releases <br />of radon are in compliance with the requirements of EPA's NESHAP program and that potential <br />exposure of the public would be maintained below 10 mrem/year a the nearest receptor. <br />12. Public access to the mine site would be precluded in order to eliminate public safety <br />concerns. <br />13. Composite samples shall be acquired through quarterly waste rock grab samples and <br />analyzed once per year to ensure that the waste is still considered inert. This data and a summary <br />report shall be provided to the BLM.
