over the annual average salinity of the Colorado River at Imperial Dam. The act also
authorized construction of 4 salinity control units and the expedited planning of 12
other salinity control projects above Imperial Dam as part of the basinwide salinity
control plan.

In 1993, the Forum reviewed the salinity standards and recommended continuing the
construction of units identified in the 1974 act, the placing of effluent limitations on
industrial and municipal discharges, and the reduction of the salt-loading effects of
irrigation return flows. The plan also called for the inclusion of water quality
management plans to comply with section 208 provisions after the adoption of the
plans by the States and approval by EPA. It also contemplated the use of saline water
for industrial purposes and future salinity use control methods.

Public Law 98-569, signed October 30, 1984, amends Public Law 93-320. The
amendments to the Salinity Control Act authorized the entire U.S. Department of
Agriculture salinity control program. The amendments also authorized two new units
for construction under the Bureau of Reclamation program. Additional units will need
to be authorized to maintain the salinity standards and have been included in the plan
of implementation for the salinity control program.
