Implementation Schedule The major steps in the implementation of Phase I of the NASF are assumed to occur in the following sequence: · April 1998 - execution of Memorandum of Understanding between CDOW and CWCB for the development and operation ofthe facility, . May 1998 - begin final design, . April 1999 - complete design work, · March through May 1999 - project bidding and selection of a construction contractor, . June 1999 - begin construction, . May 2000 - end construction, . June 2000 - begin facility operation. Impacts and Permittinl! The primary impacts from the project would be associated with construction, which would involve the temporary disturbance of 100 to 200 acres of land. The only other major impact may be the possible discharge of effluent from the facility and the potential creation of additional wetlands by use of the effluent. The project will be located entirely on private property, however, it is possible that a 404 Permit will be required for potential wetlands impacts resulting from effluent discharge. (At this time it is not actually known ifthere will be any discharge of effluent.) It is also likely that an NPDES discharge permit would be required from the Colorado Department of Public Health and Environment. As noted above, the existing well permits will probably have to be revised to include the category of commercial use for each of the three wells in the confined aquifer. Additional permits and adjudication for a plan for augmentation will be required for any new wells in the unconfined aquifer. Selection of Desil!n Enl!ineer In February 1998, the firm of FishPro was selected as the design consultant in a competitive selection process. The selection committee consisted of CDOW and CWCB staff members. 3-7
