Notes:
Note A: The Director shalluse the Nevada standards in consideringwhether to issue a permit for a stationary source and shall ensure that the stationary sourcewill not cause the Nevada standardsto be exceeded 

### in areas where the general public has access. Note 

### B: These standards,other 

### than for ozone,particulate matter, and those based on annual averages, must not be exceeded more 

### than once per year. The 1-hour ozone standard is attained when the expected number of days per calendaryear with a maximum hourly average concentration above the standard is equal to or less than one. The PMlo 24-hour standard is attained when the expected number of days per calendaryear with a 24-hour average concentration above the standard,rounded to the nearest 10 @m3, is equal to or less than one. The expected number of days per calendar year is generally based on an average of the number of times the standard has been exceeded per year for the last 

### 3 years. The National standards are to be used in determinations of attainment or nonattainment. Note 

### C: Where applicable,concentration isexpressed first in units 

### in which it was adopted. 

### All measurements of air quality that are expressed as mass per unit volume, such as micrograms per cubicmeter, must be corrected to a reference temperature of 

### 25OC and a reference pressure of 760 

### mm of Hg (1,O 13.2millibars); "ppm" in this table refers to parts per million by volume, or micromoles of regulated air pollutant per mole of gas; "pg/m3" refers to micrograms per cubic meter. Note D: Any referencemethod specified in accordance with 40

### C.F.R. Part 53 may be substituted. Note 

### E: National primary standards are the levels of air quality necessary, with 

### an adequate margin of safety, to protect the public health. Note 

### F: National secondary standards are the levels of air quality necessary to protect the public welfare from any known or anticipatedadverse effectsof a regulated air pollutant.
