DMG Permit No. M~8-112 Quarterly, Monthly and Bi-weekly Sampling Dear Mr. Dillie: All required sampling was completed during the month of April. Enclosed are analytical reports from Sangre De Cristo Lab (SDCj for the recent bi-weekly and monthly sampling period as specified in the April 1992 Abatement Plan. Also enclosed are the results of CORE tabs ongoing HCT testing. The cross-reference table between sample identification numbers, sample types and sample locations is also attached. As specified in TR-006, calculated free and wad cyanide values for the process point samples are enclosed. Field and rinse blanks were collected as part of the QA/QC. Analysis that have not been received will be forwarded to you as I receive them. BMRI met with the DMG on April 22, 1999 regarding TR-26 approval and implementation. All surface water stations were inspected and RS-4 and RS-6 were found to be dry. Vacuum on the lysimeters was verified and no water was present fo sample. When we checked the piezometers on the main embankment of the tailings impoundment on 05/04/99, the piezometers were dry or contained well below 12 inches of woter. The two west pit piezometers were measured for depth to water on 05/03/99, with the following result: BF-Iwas 1 1.95 ft and BF-2 was 15.65 ft. The ocher piezometers in the West Mine area were also checked with the following result: PW-1 was 14.15 ft, PW-2 was 15.00 ff, PW-3 was 23.50 ft and PW-4 was 26.05 ff. The underdrain was measured at approximately 33 gpm. The collection pond's leak detection system was sampled and pumped dry. The leak was measured at approximately 33 GPAD.
