This notice cited "failure to maintain surface water monitoring devices (crest stage gages, and single stage samplers) in accordance with the monitoring program submitted under Sec.2.05.6(3)(b)(iv)". This letter will serve as BME's explanation and a history of events concerning these monitoring devices which led to the issuing of the NOV. The sites which require the stated monitoring devices aze: SW31-1 (Upper Scullion Gulch), SWl-1 (Lower Red Wash), SWl 1-1 (Lower Scullion Gulch), SW23-1 (Red Wash Tributary below Refuse Pond RP-I), SW24-1 (Upper Red Wash). In the past, these monitoring devices have repeatedly been washed out, silted in or vandalized; - The monitoring devices located along Red Wash (SW1-1, SW24-1) have washed out or silted in every year with the initial spring run-off, and have been re-built or replaced annually up through the spring of 1996. Monitoring from SW31-1 location was discontinued through a Technical Revision on 7/22/87 until Spring of 1996. An inspection in spring of 1996 indicated the monitoring device was missing. Whether or not this was due to vandalism is unknown. There was no flow recorded at this time, or during subsequent Quazterly Inspections since monitoring resumed in spring of 1996. There has only been one event recorded (3/95) since monitoring began. Since 3/95, monthly inspections have indicated that this device is no longer in place, cause unknown. - SW23-1 is to be monitored only if there is a discharge from the sediment pond (RP-1).
