| Relation | Central Utah Project; Western Waters Digital Library; page 2 mr D L crandall 3 the extent to which expanded operations ofthe odthe of the phosphate mine will have an impact upon the water quality of tyzack reservoir these aspects of the proposed project are significant due to the upstream proximity of the phosphate plant and the susceptibility of impounded waters to algal blooms and other eutrophic conditions the phosphate operations owned by stauffer chemical company are operating under a no discharge permit issued by EPA currently the plant has submitted plans for implementing this no discharge requirement and EPA has approved these plans however there remains the possibility of an accidental discharge associated with some storm event to insure the integrity of the proposed tyzack reservoir information should be gathered to address this potential problem including detailed information on the scope timing and duration of the water quality sampling program that is proposed in this draft statement in conjunction with efforts to quantify the potential water quality impacts of the phosphate operation measures should be taken to assure the proper level of industry responsibility As reco recommended ended by the FWPCA water quality control study such measures should include a contingency tin gency plan for emergency control of runoff from the phosphate mining area in any water delivery agreement made with the industry salinityincrease salinity increase in the lower colorado river it is estimated in the environmental statement that the jensen unit will result in an increase in salinity of 1.6 16 ig lg mgl mg1 ngi mgt at imperial dam it is unclear however as to whether this figure included only the effects of depletion for municipal industrial and irrigation uses or if salt loading effects from increased irrigation use is ii included assuming that the salt loading is included it is of interest to us as to how the salt loading was estimated depending upon the sophistication of the estimation methods the effects of various on site measures for reducing the salt load can be investigated and the effects quantified the environmental statement indicates that any salinity increases arising from development of the jensen unit are expected to be offset by the colorado river water quality improvement program and related activities provided by the salinity control act although we are aware of the activities of the colorado river basin states in formulating this program it is our position that where feasible individual projects should include salinity control measures within the jensen unit effort should be made to control the uptake of salts in irrigating by 1 provisions to prevent sediment runoff of irrigation waters tailgater tailwater tail water 2 the use of irrigation scheduling throughout the project so as to optimize the amount of water used 3 the use of efficient methods of application 134 1 34 |
