(a) the basis of the need for the facility;

(b) the nature of the probable environmental impact;

(c) that the facility minimizes adverse environmental impact, considering the state of available technology and the nature and economics of the various alternatives;

(d) in the case of an electric, gas, or liquid transmission line or aqueduct:

(i) what part, if any, of the line or aqueduct will be located underground;

(ii) that the facility is consistent with regional plans for expansion of the appropriate grid of the utility systems serving the state and interconnected utility systems; and

(iii) that the facility will serve the interests of utility system economy and reliability;

(e) that the location of the facility as proposed conforms to applicable state and local laws and regulations, except that the department may refuse to apply any local law or regulation if it finds that, as applied to the proposed facility, the law or regulation is unreasonably restrictive in view of the existing technology, of factors of cost or economics, or of the needs of consumers, whether located inside or outside the directly affected government subdivisions;

(f) that the facility will serve the public interest, convenience, and necessity;

(g) that the department or board has issued any necessary air or water quality decision, opinion, order, certification, or permit as required by 75-20-216(3); and

(h) that the use of public lands or federally designated energy corridors for location of a facility defined in 75-20-104(10)(a) or (10)(b) was evaluated and public lands or federally designated energy corridors for that facility were selected whenever their use was compatible with:

(i) the requirements of subsections (1)(a) through (1)(g); and

(ii) transmission line reliability criteria established by transmission reliability agencies for a facility defined in 75-20-104(10)(a).

(2) In determining that the facility will serve the public interest, convenience, and necessity under subsection (1)(f), the department shall consider:

(a) the items listed in subsections (1)(a) and (1)(b);

(a) that the facility or alternative incorporates all reasonable, cost-effective mitigation of significant environmental impacts; and

(b) that unmitigated impacts, including those that cannot be reasonably quantified or valued in monetary terms, will not result in:

(i) a violation of a law or standard that protects the environment; or

(ii) a violation of a law or standard that protects the public health and safety.

(4) For facilities defined in 75-20-104, if the department cannot make the findings required in this section, it shall deny the certificate.
