<br />O~'21?') <br />u ..... <br /> <br />"In such a manner so as to protect. mitigate adverse impacts to and improve the values <br />for which Grand Canyon National Park and Glen Canyon National Recreation Area <br />were established, including, but not limited to, natural and cultural resources and <br />visitor use." <br /> <br />GCPA also tells the Secretary to implement this Title in a manner consistent with existing <br />laws that govern allocation, appropriation, development, and exportation of the waters of the <br />Colorado River. <br /> <br />Section 1803 validated the interim operating criteria adopted by the Secretary in 1991 and <br />provided for consultation, a deviation process and a method for termination.. <br /> <br />Section 1804 required preparation of an EIS, adoption of operating criteria and plans, reports <br />to Congress and allocation of costs. The EIS requirement merely validated the Secretary's <br />previous direction to Reclamation earlier and provided time frames. The final EIS was filed <br />in March of 1995 and a Record of Decision (ROD) signed October 1996. The ROD changed <br />only two flow parameters from the those shown in the EIS preferred alternative, they were: <br />increasing the maximum flow from 20,000 cfs to 25,000 cfs and increasing the upramp rate <br />from 2500 cfslhr to 4000 cfslhr. Following signing of the ROD the Secretary adopted a set of <br />operating criteria and a 1997 plan of operation, copies of which are attached in the appendix. <br />This terminated the interim flow criteria. <br /> <br />The Secretary's 1998 plan of operations is included as the final section of the report. Glen <br />Canyon Dam was operated in 1997 and will be operated in 1998 in compliance with the <br />ROD, operating criteria and the plans of operation. <br /> <br />Reclamation has begun the process of reallocating the costs of construction, operations, <br />maintenance, replacement and emergency expenditures among the purposes directed in <br />section 1802 and the purposes established in the Colorado River Storage Project Act of April <br />11,1956. Work began in FY 1997 and will continue in FY 1998. All work will be <br />performed in consultation with the Secretary of Energy. <br /> <br />3 <br />
