Reclamation and other Federal agencies share the responsibility to protect these <br />assets, There have been no trust assets identified in the project area, and therefore no impact on <br />these assets is predicted, <br /> <br />Environmental Justice <br /> <br />Executive Order 12898 on Environmental Justice provides that Federal agencies analyze <br />programs to assure that they do not disproportionately adversely affect minority or low income <br />populations or Indian Tribes. There are no potentially affected minority or low income <br />populations in the project area and no adverse effects related to environmental justice are <br />predicted. <br /> <br />Socioeconomic <br /> <br />Socioeconomic resources related to the proposed action can be broken into two general <br />categories: I) Hydropower Production ['rom the Aspinall Unit and 2) Commerical Guiding <br />Services for tishing '-lnd t10'-lt guides, <br /> <br />Hvdropower Production <br /> <br />The Aspin'-lll Unit is oper'-lted to meet base dem'-lnd '-lnd daily peak power demands and reserve <br />criteria.

Cryswl Reservoir <br />, , provides storage space for smoothing peaking power releases from Morrow Point Reservoir to <br />meet the relatively uniform river flows required to provide the existing Uncompaghre Project <br />diversions through the downstream Gunnison Tunnel in the summer months. Within a 24 hour <br />period. releases for power production from Blue Mesa Dam can fluctuate between o and 3.400 <br />cfs. Morrow Point Dam between 0 and 5.000 cfs. while Crystal's releases typically fluctuate in <br />the 50 cfs range. When the Aspinall Unit is at maximum power production. daily fluctuations in <br />releases from Crystal Dam may increase to the 200 cfs range. <br /> <br />The Morrow Point Power Plant is able to generate electricity with a water surface elevation <br />range of 7.160 ft. to 7,100 ft, As Morrow Point Reservoir's water surface elevation drops. <br />gener'-ltion efficiency would be lost and fewer meg'-lw'-l[[s of power would be generated per acre- <br />feet released.
