Texas Health and Safety Code - HEALTH & SAFETY § 386.105. Calculation of Cost-Effectiveness

(a) In calculating cost-effectiveness, one-time grants of money at the beginning of a project shall be annualized using a time value of public funds or discount rate determined for each project by the commission, taking into account the interest rate on bonds, interest earned by state funds, and other factors the commission considers appropriate.

(b) The commission shall establish reasonable methodologies for evaluating project cost-effectiveness consistent with Subsection (a) and with accepted methods.

(c) The commission shall develop protocols for calculating oxides of nitrogen emissions reductions not otherwise required by state or federal law in nonattainment areas and affected counties of this state from representative project types over the life of the projects.

(d) The commission may include in cost-effectiveness determinations only reductions in oxides of nitrogen emissions that are achieved in nonattainment areas and affected counties of this state.

(e) The commission may allow for the apportionment of credits associated with a project between the plan and another program or entity if the part of the credit assigned to the program that is part of the plan still meets any applicable cost-effectiveness criteria.
