In order to facilitate your revision I've presented the MLRD comment followed by CYCC's response. MLRD COMMENT: Alluvial Wells I/ 1. CYCC did not collect a full suite water quality sample for the third quarter period at alluvial wells 006-AW-2 and 005-AZ-3. We understand that the sites were frozen during April; however, this did not preclude sampling during May or June. Please explain this omission. RESPONSE: The field samples for the above referenced wells were obtained for the third quarter, but samples were not obtained fur full suite analysis. I do not know why the samples were missed, the monitoring schedule had been established and was not followed. The person who was responsible for the sampling is no longer employed by Cyprus, therefore, I can not question him to determine the reason for failing to fulfill the sampling requirement. The monitoring commitments have been reviewed by the current staff so that his situation should not arise in the future. MLRD COMMENT: /Spoil Wells Only one of the two required full suite samples was collected at spoil well 026-SP-3. Please explain this omission. RESPONSE: This well is a low producer and a sufficient quantity of water was not available for analysis. This will continue to be an ongoing occurrance if sufficient water is not available in the well. c~rp~us
