"(2) A plan to achieve compliance with these standards
as expeditiously as practicable provided that:

"(i) The plan shall identify State and Federal
regulatory authorities and programs necessary to
achieve compliance with the plan.

"(ii) The salinity problem shall be treated as a
basinwide problem that needs to be solved in order
to maintain lower main stem salinity at or below
1972 levels while the Basin States continue to
develop their compact-apportioned waters.

"(iii) The goal of the plan shall be to achieve
compliance with the adopted standards by July 1,
1983. The date of compliance with the adopted
standards shall take into account the necessity for
Federa 1 salini ty control actions set forth in the
plan, Abatement measures within the control of the
States shall be implemented as soon as practicable.

"(iv) Salinity levels in the lower main stern may
temporarily increase above the 1972 levels if con-
trol measures to offset the increases are included
in the control plan. However, compliance with 1972
levels shall be a primary consideration.

"(v) The feasibility of establishing an
institution for salinity management
evaluated.

"(d) The States are required to submit to the respective
Environmental Protection Agency Regional Administrator, estab-
lished procedures for achieving (c) (1) and (c)(2) above within
30 days of the effective date of these regulations and to
submit progress reports quarterly thereafter. EPA will on a
quarterly basis determine the progress being made in the
development of salinity standards and the implementation
plan."

The Colorado River Basin Salinity Control Forum prepared a report
entitled, "Proposed Water Quality Standards for Salinity Including Nu-
meric Criteria and Plan of Implementation for Salinity Control, Colorado
River System," in June of 1975. The Forum held public meetings in Las
Vegas, Nevada, on August 4, 1975, and Grand Junction, Colorado, on
August 7; 1975, and received written comments through August 8, 1975, on
the proposal. Based on the comments received, the Forum developed a
supplement including modifications to the report. This Supplement is
dated August 26, 1975.
