Testing and Sampling

1. To determine compliance with NAC 445B.001 to 445B.3485, inclusive, before the approval or the continuance of an Operating 

Permit or similar class of permits, the Director may either conduct or order the owner of any stationary source to conduct or have 

conducted such testing and sampling as the Director determines necessary. Testing and sampling, or either of them must be 

conducted and the results submitted to the Director within 60 days after achieving the maximum rate of production at which the 

affected facility will be operated, but not later than 180 days after initial startup of the facility and at such times as may be 

required by the Director. 

2. Tests of performance must be conducted and data reduced in accordance with the methods and procedures of the test contained 

in each applicable subsection of this section unless the Director: 

a. Specifies or approves, in specific cases, the use of a method of reference with minor changes in methodology; 

b. Approves the use of an equivalent method; 

c. Approves the use of an alternative method, the results of which he has determined to be adequate for indicating whether a 

specific stationary source is in compliance; or 

d. Waives the requirement for tests of performance because the owner or operator of a stationary source has demonstrated by 

other means to the Director’s satisfaction that the affected facility is in compliance with the standard. 

3. Tests of performance must be conducted under such conditions as the Director specifies to the operator of the plant based on 

representative performance of the affected facility. The owner or operator shall make available to the Director such records as 

may be necessary to determine the conditions of the test of performance. Operations during periods of startup, shutdown, and 

malfunction must not constitute representative conditions of a test of performance unless otherwise specified in the applicable

standard. 

4. The owner or operator of an affected facility shall give notice to the Director 30 days before the test of performance to allow the 

Director to have an observer present. A written testing procedure for the test of performance must be submitted to the Director at 

least 30 days before the test of performance to allow the Director to review the proposed testing procedures. 

5. Each test of performance must consist of at least three separate runs using the applicable method for that test. Each run must be 

conducted for the time and under the conditions specified in the applicable standard. For the purpose of determining compliance 

with an applicable standard, the arithmetic means of results of the runs apply. In the event of forced shutdown, failure of an

irreplaceable portion of the sampling train, extreme meteorological conditions, or other circumstances with less than three valid 

samples being obtained, compliance may be determined using the arithmetic mean of the results of the other two runs upon the 

Director’s approval. 

6. All testing and sampling will be performed in accordance with recognized methods as specified by the Director. 

7. The cost of all testing and sampling and the cost of all sampling holes, scaffolding, electric power, and other pertinent allied 

facilities as may be required and specified in writing by the Director must be provided and paid for by the owner of the stationary 

source. 

8. All information and analytical results of testing and sampling must be certified as to their truth and accuracy and as to their

compliance with all provisions of these regulations, and copies of these results must be provided to the Director no later than 60 

days after the testing or sampling, or both.

of 40 C.F.R. Part 60. 

b. If a source uses a continuous monitoring system for the measurement of opacity, the data must be reduced to 6-minute 

averages as set forth in 40 C.F.R. §§ 60.13(h). 

2. The provisions of this section and NAC 445B.2202 and 445B.22023 do not apply to that part of the opacity that consists of
