Quarterly assess community noise during construc~iQn and <br />semi-annually thereafter until the noise appcarsit¢ j <br />stabilize statistically. j I <br />2. Assess dominant noise sources if. significant cha',nges occur <br />in the operations. <br />3. Periodically measure dominant noise levels of m~jo~r <br />components of the facility subject to wear, induced <br />noise fluctuations (i.e., crusher, conveyor, loado'vt <br />facility, etc.) <br />4. Furnish quarterly assessment to ALM within 30 days,' of~' <br />data gathering. <br />Should the sensitive noise receptors or the monitoring program <br />ittdicate sound levels approaching or exceeding EFA standardsifor <br />speech or sleep interference, the following steps must betaken <br />to rectify the noise levels as appropriate: ~ <br />1. Use of barriers or noise control methods a:; necided <br />2. Enclosure of conveyor belt drive stations <br />3. Expediting construction of the conveyor <br />4. Staging of helicopter operations from CWI mineiopera,tions <br />area <br />5. Stringent maintenance of the belt and conveyor system, <br />crusher, loadout facil.ir.ies to minimize noise whilch 'imight <br />develop with wear <br />6. Full enclosure of the wafer/pipeli.ne pump house <br />7. Application of control measures to ventilation fan I <br />installation as it is increased in flow or size <br />8. Requiring train crews to minimize warning w}~is;tle u$age <br />In short, the requirement for a noise monitoring program is <br />included as a specific lease stipulation, is thoroughky treated in <br />the final EAR, has been previously reviewed by EPA, and is now <br />scheduled to be implemented when the lease is issued. <br />I •Ji' I i <br />~~ ~!~ IY~~~a~~~~~i~f~~l ~, , ,~ <br />
