Adjustments to Depreciation Reserve: With the procedures outlined in NMPSC Rule 340 [17.3.340 NMAC] which require frequent reviews of depreciation rates and accruals there should not develop any serious over-or under-accruals of depreciation reserves. When a utility believes that at any time an over-or under-accrual in the depreciation reserve exists, the utility shall submit by formal application to the Commission a detailed reserve requirement study and request for adjustment. This reserve requirement study shall be reviewed by the Commission and the Commission will subsequently issue its final order approving, disapproving, or modifying the adjustment.
