Technical feasibility of the alternatives.

\i

Total construction, operation and maintenance
costs and costs in dollars per ton of salt
removed from the discharge.

Closure plans to ensure termination of any
proposed discharge at the end of the economic
life of the project.

8, A statement as to the one alternative plan
for reduction of salt discharge that the
applicant recommends be adopted including an
evaluation of the technical, economic and
legal practicability of achieving no
discharge of salt.

9. Such other information as the permitting
authority may deem necessary,

IV, In determining whether a "no salt" disCharge is
practicable the permit issuing authority shall
consider, but not be limited to, the water rights and
the technical, economic and legal practicability of
achieving no discharge of salt.

V, Where "no-salt" discharge is determined not to be
practicable the permitting authority shall, in
determining permit conditions, consider:

A, The impact of the total proposed salt discharge
of each ,alternative on the lower mainstem in
terms of both tons per year and concentration,

B, Costs per ton of salt removed from the discharge
for each plan alternative.

C. The compatibility of state water laws with each
alternative,

D, Capability of minimizing salinity discharge,

E. The localized impact of the discharge,

F. Minimization of salt discharge and the
preservation of fresh water by using intercepted
groundwater for industrial processes, dust
control, etc" whenever it is economically
feasible and environmentally sound.
