Siqnificant conclusions and recom~endations developed fron this plannin~

effort include:

1. Population in the study area is c~rrently estimated at 141 ,noD and under

2. The total capital cost of the facilities recom~ended for construction in

this plan is'approxi~ately 14.5 ri~lion dollars based on 1974 construction

costs.

Eneray resource development \.!.ithin He Colorado River Dasin could result
in a population growth to 315,000 by 1993. This growth ~iOuld increase
the ca~'ita1 expenditure for facil ities in accordance ~:iththe recommended

plan by approximately t nlillion dollars based on 1974 construction costs.
The pri~ary inoact area due to energy resource development \',ill be the
rifle and Grand Valley subbasins and involve G1en~lood SprinC]s, Ne~f Castle,

Silt; Rifle, Grand Valley, GeBeque, Palisade, Fruita, and Grand Junction.

4. The recomnlended basin plan ~:i11 require nitrification to a level of 1.5

moll amonia-nitronen at the following facilities: Granby on the Fraser

Piver; Vail, Upper Eaole Valley, Lake Creek and Eaa1e on the Cagle Piver;

rlor,trose an the Uncor,lpahol'e River; !1ount Crested Flltte on the Slate River;
and thet'nion Carbide-I~ravan facility on the San tii')uel River. The
Grand Junction area '~,i11 require n~trificaticn to reduce ammonia-nitrooen
to a level of S 1:'<1/1. flaste10ad allocations based on a~~;onia-nitroqen

discharges have been developed for the Colorado Piver and its tributaries

in areas of anticipated develop~ent andr;rc~!th.
