1. Colorado River Salinity Program

The Upper Colorado River Commission has continued its
interest and involvement in the Colorado River Basin salinity
problem. The Commission staff has worked with representatives
of the Commission's member States in coordinating and correlat-
ing activities with other State and Federal agencies, particularly
the Colorado River Basin Salinity Control Forum which is com-
posed of representatives from the seven Colorado River Basin
States. The Forum has developed water quality standards and a
plan of implementation to meet the Environmental Protection
Agency Regulation (40 CFR Part 120, Water Quality Standards
- Colorado River System: Salinity Control Policy and Standards
Procedures).

Section 303 of the Clean Water Act requires that water qual-
ity standards be reviewed from time to time and at least once
during each three-year period. The Forum in 1987 reviewed the
existing State-adopted and Environmental Protection Agency-
approved numeric salinity criteria and found no reason to recom-
mend changes for the three lower mainstem stations.
