That the findings set forth in this Resolution are hereby in all things approved. Section 2. That, without prejudice to future litigation of any issue identified by ACSC, the Town Council finds that the settled amount of an increase in revenues of$22.78 million for ACSC Cities represents a comprehensive settlement of gas utility rate issues affecting the rates, operations, and services offered by Atmos Mid-Tex within the municipal limits arising from Atmos Mid-Tex's 2021 RRM filing, is in the public interest, and is consistent with the Town's authority under Section 103.001 of the Texas Utilities Code.

The Weather Normalization Adjustment shall apply to all temperature sensitive residential and commercial bills based on meters read during the revenue months of November through April. The five regional weather stations are Abilene,Austin, Dallas, Waco, and Wichita Falls. Computation of Weather Normalization Adjustment The Weather Normalization Adjustment Factor shall be computed to the nearest one-hundredth cent per Ccf by the following formula: (HSFi x (NDD-ADD) ) WNAFi = Ri (BLi + (HSFi x ADD) ) Where i = any particular Rate Schedule or billing classification within any such particular Rate Schedule that contains more than one billing classification WNAFi = Weather Normalization Adjustment Factor for the ith rate schedule or classification expressed in cents per Ccf Ri = Commodity Charge rate of temperature sensitive sales for the ith schedule or classification. HSFi = heat sensitive factor for the ith schedule or classification divided by the average bill count in that class NDD = billing cycle normal heating degree days calculated as the simple ten-year average of actual heating degree days. ADD = billing cycle actual heating degree days. Bli = base load sales for the ith schedule or classification divided by the average bill count in that class The Weather Normalization Adjustment for the jth customer in ith rate schedule is computed as: WNA;= WNAFi x qq Where qq is the relevant sales quantity for the jth customer in ith rate schedule.
