Box 152 <br />Fraser, CO 80442 <br />RE: Project No. 90-13.1 Reclamation Resources <br />Dear Mr. Lazier: <br />Enclosed please find a copy of the evaluation you requested. In <br />SURVEYORS <br />• the reconfigured, compacted impoundment has been designed with more <br /> adequate stability; <br />• based upon lab tests on the soils, the impoundment should self-seal <br /> once mining operations commence; <br />• the only location on the site affected by a 25-year flood event is <br /> that portion of the impoundment immediately adjacent to t e stream, <br /> <br />• and that area is protected to six feet <br />the slope analysis confirms that onsite with riprap; <br />runoff from the d <br />sturbed <br /> area will flow to the impoundment; <br />• the drainage that will be employed to c arry ditch water f om the <br /> galvanized pipe to the impoundment has been and will be a fective <br /> Eor that purpose and is not subject to catastrophic failu e. <br />Thank you for the opportunity to work with you on this matter. If <br />any questions, please Eeel free to contact me at (303) 980-6155. <br />Sincerely, <br />~~~~~ <br />Fred C. Ladd <br />President <br /> <br />have <br />FCL:cev <br />Enclosure <br />
