Resolution Safety Contingencies
All Contingencies MUST be met to proceed:
1. Project cost must be the same or less than the budget;
2. Project savings must be the same or more than the budget;
3. The OSFC and the Dept. of Energy must review and approve the proposed project as submitted.
If any of these contingencies are not met, the district has no obligation to proceed, nor any monetary obligation.
