Any unit of state government may offer such technical assistance as it is able to any board or commission requesting such assistance. However, such technical assistance may not include granting a permit, settling a dispute, accepting a plan, establishing a coordinated drainage area, or performing any other decision function relegated to boards or commissions under the provisions of this chapter and chapter 46A-11. A unit of state government providing technical assistance may require reasonable reimbursement for its expenses. The provisions of this section do not prohibit the Water Management Board from taking action or providing assistance pursuant to the provisions of this section and §§ 46A-10A-9.1 to 46A-10A-9.5, inclusive.
