Sec.  61.34  Air sampling.



    (a) Stationary sources subject to Sec.  61.32(b) shall locate air 

sampling sites in accordance with a plan approved by the Administrator. 

Such sites shall be located in such a manner as is calculated to detect

reasonable time allowance for instrument maintenance and calibration, 

for changing filters, or for replacement of equipment needing major 

repair.

    (c) Filters shall be analyzed and concentrations calculated within 

30 days after filters are collected. Records of concentrations at all 

sampling sites and other data needed to determine such concentrations 

shall be retained at the source and made available, for inspection by 

the Administrator, for a minimum of 2 years.

    (d) Concentrations measured at all sampling sites shall be reported 

to the Administrator every 30 days by a registered letter.
