Permit conditions prottutive of grouadwate r~wllifJll~alsWO be established througd the sasae technical
revision process, which is described sl+ana4 Until the permit is revised to include permit
conditions protective of groundwater, the operator is precluded from injecting fluids under this
permit for the purpose of solution mining.
if the ambient groundwater quality information collected under the characterization plan proves
to be inadequate W establish permit eonditioas protective of groundwater, the Board may
require additional characterizatoa of grotmdwatu prior to allowing injection of fluids for
solution mining.
If the ambient ground water quality information demonstrates tbat_ the existing and reasonable
potential fIM1M uses of groandwater may not be protected by permit conditions under the none
plan described in the permit application, ar in the permit as it may be revised, rhea the Board
may bar the operator from further executing the mine plan sad require reclamation of any
disturbance that has occurred up to that point.
The technical revision process to be employed will occur through the following steps: (1)
Provision of the groundwater data to the Division as it is arruaaulated rather than a5 a single
submittal at rite sad of the data gathering period. The Division wi11 disseminate the data to the
parties to the permit application process. This procedure will assure that interested parries have
adequate opporttmity to evaluate the data.
{2) Once all of the required ambient groundwater data has been accumulated, the operator will
apply for a technical revision to incorporate the data into the permit and to establish permit
conditions protective of groundwater. The operator will follow the public notice procedures of
Rule 1.6.2 mtd Rule 1.6.3. Public comment on the technical revision wi11 be in accordance with

Condition 3 -American Soda will provide a technical revision to incorporate a revised list of
analytical parameters for Method Detection Limits. The TR must be approved prior to injection
of sohttion mining fluids. The Division will provide copies of the proposed TR to the objecting
Party to the application hearing and camsida its comments on the TR.
