D.C. Mun. Regs. tit. 15, § 1301
1301.1 Each public utility, competitive electric supplier, competitive natural gas supplier, and competitive local exchange carrier ("CLEC") shall be assessed according to D.C. Code Section 34-912(b) for the reimbursable budgets of the Commission and the People's Counsel in the following manner:
(a) For CLECs, competitive electric suppliers, and competitive natural gas suppliers (collectively "alternative providers"), the assessments shall be equal to the ratio of the alternative provider's calendar year gross revenues to the sum of the calendar year gross revenues of all public utilities and all alternative providers times the budgets of the Commission and OPC. This calculation is subject to any adjustment pursuant to subsection (c).
(b) For public utilities, the assessment shall be the utility's proportionate share of the calendar year gross revenues of all public utilities times the budgets of the Commission and OPC less the amount to be reimbursed by the alternative providers in subsection (a).
(c) In any year in which there is a first year CLEC(s) providing local service, the CLEC(s) shall be assessed twenty-five thousand dollars ($25,000) pursuant to D.C. Code § 34-912(b)(4). The $25,000 assessment shall be allocated equally between the operating budgets of the Commission and OPC. For purposes of the calculations in subsection (a), the first-year CLEC(s) total revenues shall be deducted from the total gross revenues of all companies and the total amounts to be assessed for the Commission's and OPC's budgets shall be reduced by the amount of assessment to the first year CLEC(s).
1301.2 On April 15th of each year, each utility, competitive electric supplier, competitive natural gas supplier, and CLEC shall file its gross jurisdictional revenue figures for the preceding calendar year ending December 31st.
