Section I, A,l,b; the following factors relating to the
potential discharge:

a. Existing tonnage of salt discharged and volume
of eff1 uent.

b. Cost of modifying existing industrial p1~nt to
provide for no salt discharge.

c. Cost of salt minimization.

3. In determining wlat permit corditions shall be required,
thp Department of Health shall consider the items as
follows:

'(1) Where nO-discharge is determined to be impracticable:

{a) The impact of the total proposed salt

concentration and the economic impact of the
increased salt load.

(b) Costs per ton of salt removed from the
