Estimated profits
(2) Estimated profits. For purpose of this paragraph, the term estimated profits means the estimated gross receipts from the sale of recovered wastes reduced by the sum of the (i) estimated average annual maintenance and operating expenses, including utilities and labor, allocable to that portion of the facility which is certified as a treatment facility pursuant to paragraph (a)(1)(i) of this section which produces the recovered waste from which the gross receipts are derived, and (ii) estimated selling expenses. However, in determining expenses to be subtracted neither depreciation nor amortization of the facility is to be taken into account. Estimated profits shall not include any estimated savings to the taxpayer by reason of the taxpayer's reuse or recycling of wastes or other items recovered in connection with the operation of the plant or other property served by the treatment facility. (3) Special rules. The estimates of cost recovery required by subparagraph (2) of this paragraph shall be based on the period referred to in paragraph (a)(6) of this section. Such estimates shall be made at the time the election provided for by section 169 is made and shall also be set out in the application for certification made to the Federal certifying authority. There shall be no redetermination of estimated profits due to unanticipated fluctuations in the market price for wastes or other items, to an unanticipated increase or decrease in the costs of extracting them from the gas or liquid released, or to other unanticipated factors or events occurring after certification.
