Reclamation was interested in changing the 10% band <br />width because it believed that the ROD and Operating Criteria didn't specify that kind of <br />flexibility. Instead, Western was allowed to use up to 1,000 cfs for regulation purposes. - <br />Compliance was to be monitored by SCADA using a one hour integrated value. It was thought <br />that, even though a downramp at anyone moment of time could be as high as 2,500 cfs (1,500 <br />cfs + 1,000 cfs), it would be uncommon for the downramp to exceed 1,500 cfs since this is <br />recorded as an integrated value over the hour. <br /> <br />IV.
