<br />'OINT PUBLIC NOTICE
<br />
<br />AND
<br />STATE OF COLORADO, DEPARTMENT OF HEALTH
<br />
<br />TO WHOM IT MAY CONCERN:
<br />
<br />SubJed: Application for a Department of the Army Permit under Section 404 of the Clean Water Act
<br />(CWA) and for water quality certification under Section 401 of the CWA to discharge dredged and/or fill
<br />material in the Colorado River and Roan Creek, as shown on the attached drawings,
<br />
<br />Applicants: Colorado River Water Conservation District, Box 1120, Glenwood Springs, Colorado 81602,
<br />and Bluestone Water Conservancy District, c/o Mr. Carlos Carpenter, DeBeque, Colorado 81630.
<br />
<br />Location: The project site is approximately 4,000 feet downstream of the confluence of Roan Creek and
<br />the Colorado River, near DeBeque, Mesa County, Colorado,
<br />
<br />Purpose: The purpose of the project is for the development of Bluestone water rights as part of a lease
<br />agreement between the applicants as lessors and Getty Oil Company and Conoco Shale Oil, Incorporated,
<br />as lessees. The construction of the facilities is necessary for placing the water rights to beneficial use as
<br />industrial, irrigation, and municipal water supplies and other beneficial uses.
<br />
<br />Project Description: The applicant proposes to discharge approximately 9,090 cubic yards (cy) of
<br />dredged and fill material to facilitate the construction of a reinforced concrete intake structure along with
<br />a pumping plant with ultimate capacities of 50 cubic feet per second (ds), a 17,700-foot pipeline, and a
<br />6,000-foot canal to deliver 15 ds to the head oftwo irrigation ditches in Roan Valley. Passive intake screens
<br />will be utilized. Thirty-five ds of water will be used for industrial purposes. This depletion was assessed as
<br />part of the GCC Water project in the Clear Creek Shale Oil Project Environmental Impact Statement (EIS)
<br />(BLM, 1983), the Getty and Cities Service Shale Oil Project EIS (COE, 1984), and Associated Biological
<br />Opinions by the U,S, Fish and Wildlife Service. This 35 ds will be equally divided between the Getty Shale
<br />Oil Project and the Clear Creek Shale Oil Project. The remaining 15 ds will be diverted at the proposed
<br />structure on behalf of the Colorado River Water Conservation District and Bluestone Water Conservancy
<br />District for irrigation and municipal uses, A system consisting of pumps, pipeline, and canal will be
<br />constructed to deliver 15 ds from the intake to Roan Creek immediately upstream of the diversion
<br />structure of the reservoir and Roan Creek No.2 (Town) Ditches. Approximately 3,090 cubic yards of
<br />material (290 cy of concrete, 1,600 cy of backfill, and 1,200 cy of riprap) will be used for the intake.
<br />Approximately 105,000 cubic yards of material will be excavated for the construction of the intake,
<br />pumping plant, and access road. Approximately 6,000 cubic yards of this material will be used in the
<br />construction of the temporary cofferdam. The temporary earthen cofferdam will be constructed in the
<br />river during a low-flow period to divert the river around the site during the construction period. The fill
<br />material will consist of soil and rock fragments excavated from the site during construction of the access
<br />road and preparation of the pumping plant site. The cofferdam will remain in place during the
<br />construction period which will be approximately 4 months. Upon completion of the project, the
<br />cofferdam will be removed and the spoil will be placed adjacent to the river in the vicinity of the
<br />construction site. The disposal site will be located above normal high water elevation, and materials will be
<br />placed in a manner which will prevent reentry into the waterway.
<br />
<br />The two buried crossings at Roan Creek will be done during low flow periods. Material excavated from the
<br />trench will be used to temporarily direct flow away from the work area, The pipeline would then be
<br />recovered with this material and Roan Creek returned to its normal channel. No imported material will be
<br />used, These two crossings qualify under a nationwide general permit for utility line crossings,
