Grant in the proceeding. CUB' s amended proposed budget shows eligible expenses in the
amount of$36,250; and it seeks an amended Issue Fund Grant in the amount of$29,000,
with the additional $10,000 coming from the 2024 Arista Utilities Issue Fund. In support
of its request, CUB states that there is good cause to support approving the amended
budget because the scope, complexity of issues and changes in the schedule have resulted
in the need for additional funding that were not anticipated when CUB submitted its
initial proposed budget.
