NAC445B.3673. Existing thermal unit that emits mercury: Contents of phase-1 application; sampling and testing for tier-1 thermal unit.

A phase-1 application or an application for a revision of a mercury operating permit to construct which was issued pursuant to a phase-1 application for an existing thermal unit that emits mercury must include:

     1. An identification and a description of any equipment for the control of mercury emissions, including, without limitation, any controls that are presumptive NvMACT; and

     2. A proposed monitoring plan which must be complied with by the applicant until a mercury operating permit to construct is issued pursuant to the phase-1 application and which includes, without limitation:

     (a) For a tier-1 thermal unit that emits mercury:

          (1) Procedures for the operation and maintenance of the thermal unit.

          (2) Methods of the monitoring of and recordkeeping for any controls for mercury processes and emissions.

          (3) A proposed schedule for sampling and testing of mercury emissions and tests of performance to be conducted on an annual basis in accordance with the procedures set forth in NAC 445B.252. The owner or operator of the thermal unit that emits mercury must conduct the initial sampling and testing of mercury emissions and tests of performance and submit the results of the initial sampling and testing and tests of performance to the Director not later than December 31, 2006. After the owner or operator of the thermal unit has submitted the results of the initial sampling and testing of mercury emissions and tests of performance, the owner or operator may submit a request to the Director to waive the requirement for annual sampling and testing of mercury emissions or consider other schedules for the frequency with which such sampling and testing and tests of performance must be conducted.

          (4) A requirement to report the level of mercury emissions on an annual basis which must be based on mercury emissions test data.

          (5) A requirement to report any mercury co-product on an annual basis.

     (b) For a tier-2 thermal unit that emits mercury:

          (1) Procedures for the operation and maintenance of the thermal unit.

          (2) Methods of the monitoring of and recordkeeping for any controls for mercury processes and emissions.

          (3) A proposed schedule for sampling and testing of mercury emissions and tests of performance for the thermal unit that emits mercury.

          (4) A requirement to report the level of mercury emissions on an annual basis which must be based on mercury emissions test data.

          (5) A requirement to report any mercury co-product on an annual basis.
