<br />October 29, 1992 <br />Pape 3 <br />DOMG Concern <br />e) What is meant by the footnote on page 8-9 of Exhibit 8 "...; 4 <br />monthly lab samples obtained once runoff begins"? <br />CYCC Response <br />~~ As previously discussed, this footnote is specific to Site 14. This <br />site normally only discharges for a short period in the spring, and <br />as a result cannot be sampled on a quarterly basis for Full suite <br />analysis. This necessitates a flexible sampling scheme similar to <br />that for the other surface sites of 4 Full suite analyses being <br />conducted during the limited-duration runoff period. <br />DOMG Concern <br />f) Please include a graph of precipitation vs year for the life of <br />the mine. This data is useful during review and is also required if <br />Cyprus infers hydrologic changes due to climatic changes. <br />CYCC Response <br />The requested graph will be submitted as part of the 1992 AHR. <br />DOMG Concern <br />g) Many elevation errors were noted on the elevation listing in the <br />AHR, the Hydrologic Monitoring Plan Map, and Table 1. Specifically <br />Sites 8, 06-82-74c, 302, 307, 301, and 69 have errors or <br />inconsistent values for elevations. Please correct all documents to <br />be consistent. <br />CYCC Response <br />O1L The requested corrections will be made. <br />DOMG Response <br />h) Site 1001 should be removed from the table and a note added to <br />site 16 explaining that it replaced 1001 in 1989. <br />CYCC Response <br />~~ The correction will be incorporated into the 1992 AHR. <br />
