         3. For a phase-2 application or an application for the revision of a mercury operating permit to construct which was issued pursuant to a phase-2 application for a tier-1 thermal unit that emits mercury or a tier-2 thermal unit that emits mercury, within 9 months after the official date of submittal, the Director shall:

         (a) Propose the conditions for a mercury operating permit to construct or a revision of a mercury operating permit to construct for the thermal unit that emits mercury; and

         (b) Make a determination of NvMACT for the thermal unit that emits mercury in which the Director shall consider the following for each thermal unit that emits mercury:

              (1) The maximum degree of reduction of mercury emissions that is achievable for the thermal unit after considering:

                   (I) The cost of achieving such a reduction; and

                   (II) Consistent with section 112(d)(2) of the Act, any nonair quality health and environmental impacts and energy requirements for each method or technology to control mercury emissions from the thermal units that emit mercury to implement NvMACT.

              (2) The measures that reduce the volume or eliminate mercury emissions through process changes, substitution of materials or any other modifications.

              (3) The enclosure of systems or processes to eliminate mercury emissions.

              (4) The collection, capture or treatment of mercury emissions.

              (5) The design, equipment, work practice or operational standards of the thermal unit that emits mercury, including, without limitation, the requirements for training and certification of operators of the thermal unit that emits mercury.

              (6) The differences in the age, remaining operating life and configurations of similar thermal units that emit mercury. The Director may also consider the differences in the concentration of mercury in the ore, size and any other relevant factors of the similar thermal units that emit mercury.

              (7) Any combination of subparagraphs (1) to (6), inclusive.

         4. If, after the official date of submittal of an application pursuant to subsection 1, the Director discovers that additional information is required to act on an application, the Director may request additional information necessary to determine whether the proposed construction or operation will comply with all of the requirements set forth in NAC 445B.3611 to 445B.3689, inclusive. The applicant must provide in writing any additional information that the Director requests within the time specified in the request of the Director. Any delay in the submittal of the requested information will result in a corresponding delay in the action of the Director on the application submitted to the Director.

         5. The Director’s review and the proposed conditions for a mercury operating permit to construct or a revision of a mercury operating permit to construct must be made public and maintained on file with the Director during normal business hours at 901 South Stewart Street, Suite 4001, Carson City, Nevada 89701, and at a location to be determined by the Director in the air quality region where the source is located, for 30 days to enable public participation and comment.
