Colorado 81626 (30318248246 ~~~~~~® Mr. Gregg Squire MAY 21988 Colorado Mined Land Reclamation Division MINED LAND 423 Centennial Building RECLAMATION DIVISION 1313 Sherman Street Denver, Colorado 80203 RE: Technical Revision to Hydrologic Monitorincf Requirement T.R. No. 9, Permit No. C-81-044 Dear Mr. Squire: Per our discussion, I have attached copies of revised Table 1 and • 3 which were submitted in the above referenced technical revision. The revised will clarify the requirements of Cyprus Empire's hydrologic monitoring program as discussed below. The approved monitoring is presented in Exhibit: 29 of the above permit, and summarized in Table 3, Parts 1 through 3 of the permit. Presently a conflict exists between the requirements found in Exhibit 29 and summarized in Table 3, Farts 1 through 3. Specifically, Table 1 of Exhibit 29 differs from Table 3, Part 1 in the text of the permit by excluding Well Tlo. 5(a) from the monitoring program. Likewise, Table 2 of Exhibit 29 differs from Table 3, Part 2 in the text by excluding wells YAW-1, YAW-2, YAW-3, YAW-5, and YAW-6 from the monitoring. Also, Table 3 of Exhibit 29 differs from Table 3, Part 3 in the text by excluding surface sites Y-1, Y-2, YS-2 and YS-1 from the monitoring program. I believe the confusion arise from the fact an attempt was made to try to keep the historic sites in the permit, along with presenting the revision monitoring program. In order to accommodate this thought, I have changed the titles of Table 3, Parts 1 through 3, to include the word histori~~ to identify the prior monitoring program. I have included a new Table 3A, Parts 1 through 3 which summarizes the current (i.e. revised) monitoring program. Therefore, the monitoring z~equirements found • in both Table 3A, Parts 1 through 3, and those listed in Exhibit 29 are the same. EMPJL~E
