Section 591.13.8. Selection of a consultant when the plume of contamination is attributable to eligible and noneligible sites.

       13.8(1) The board shall include all sites sharing a common plume if each party agrees in writing to pay for their costs as determined by these rules. The board shall attempt to negotiate inclusion prior to corrective action design or actual cleanup.
