Universal Citation: NV Admin Code 445B.Sec. 1.1

Current through December 31, 2024

1. In establishing the emission limits, schedules of compliance and other measures set forth in this section to make reasonable progress towards achieving natural visibility conditions the Commission will, in accordance with the requirements of 40 C.F.R. § 51.308, take into consideration:

(a) The costs of compliance;

(b) The time necessary for compliance;

(d) The remaining useful life of the source.

2. The sources listed in this subsection must install, operate and maintain the following control measures which are necessary to make reasonable progress towards achieving natural visibility conditions, in accordance with the requirements of 40 C.F.R. § 51.308, and must not emit or cause to be emitted NOx in excess of the following limits:

(a) For power-generating unit number 4 Piñon Pine of NV Energy's Tracy Generating Station located in hydrographic area 83:

UNIT

(CT + Duct Burner)

NOx

Emission Limit (lb/106 Btu, 30-day rolling average)

Control Type

4 Piñon Pine

0.0151

Permanent use of only pipeline quality natural gas as fuel, steam injection and selective catalytic reduction

(b) For power-generating unit numbers 1 and 2 of NV Energy's North Valmy Generating Station located in hydrographic area 64:

UNIT (Boiler)	NOx
UNIT (Boiler)	Emission Limit (lb/106 Btu, 30-day rolling average)	Control Type
1	0.1029	Permanent use of only pipeline quality natural gas as fuel, Low NOx burners,
2	0.1029	and one of the following: selective noncatalytic reduction, flue gas recirculation or selective catalytic reduction

3. Each source subject to the requirements of subsection 2 shall:

(a) Install, calibrate, maintain and operate a continuous monitoring system and record the output of the system for NOx emissions in compliance with the requirements of this chapter.

(b) Maintain a contemporaneous log of monitoring and recordkeeping in accordance with the monitoring and recordkeeping requirements of this chapter and 40 C.F.R. Part 75, as adopted by reference in NAC 445B.221. Each record in the log must be:

(1) Entered into the log at the end of the shift, end of the day of operation or end of the final day of operation for the month, as appropriate; and

(2) Identified with the calendar date on which the record was entered.

(c) Annually submit a report, in accordance with the reporting requirements of this chapter and 40 C.F.R. Part 75, as adopted by reference in NAC 445B.221, which must include, without limitation, throughput, productions, fuel consumption, hours of operation and emissions.

(d) Record the occurrence and duration of any:

(1) Start-up, shutdown or malfunction in the operation of the source;

(2) Malfunction of the air pollution control equipment of the source; and

(3) Period during which a continuous monitoring system or monitoring device is inoperative at the source.

4. For each source subject to the requirements of subsection 2, the established control measures must be installed and operating and the emission limits established for each source must be met by that source not later than 36 months after approval by the United States Environmental Protection Agency Region 9 of Nevada's determination of reasonable progress towards achieving natural visibility conditions, in accordance with the requirements of 40 C.F.R. § 51.308, for that source.

5. Power-generating unit numbers 1 and 2 of NV Energy's North Valmy Generating Station must be converted from coal to the permanent use of only pipeline quality natural gas as fuel. The conversion must be completed by not later than June 1, 2027. An initial performance test and performance evaluation that meets the requirements of this chapter must be conducted for PM 10 emissions not later than 180 days after the date on which the conversion is completed.

6. If the ownership of any emission unit regulated under this section changes, the new owner must comply with the requirements set forth in this section.
