Arkansas SIP: Regulation of Plan § 7. Sampling and Monitoring Requirements

Regulatory Text:

(Approved by EPA 10/05/76 (41 FR 43904) at 52.170(c)(04) effective 10/05/76. Revisions approved by EPA 08/27/81 (46 FR 43145) at 52.170(c)(11) effective 09/28/81.)

   (a) Sampling

     (i) Any person owning or operating equipment shall, upon request, by the Director, conduct sampling to determine the opacity, rate, composition, and/or concentration of such emissions. Sampling shall be conducted at a frequency and within a period of time as specified by the Director. The sampling method shall be specified by the Director and, further, the sampling shall be conducted so as to reflect with reasonable accuracy characteristics of such emissions. Any person affected by this regulation may request the Director to approve alternate sampling techniques or other means to determine the opacity, rate, composition, and/or concentration of emissions. The Director may approve such alternate methods or means if it can be demonstrated that such alternatives will be substantially equivalent to the sampling methods specified by the Director or the Commission.

     (ii) If requested to obtain air contaminant emission data pursuant to this section, the owner or operator shall attest to and report the results so obtained to the Director within a reasonable time specified by and on forms furnished by the Department.

     (iii) Copies of all data, computations and results obtained under this regulation shall be retained by the owner or operator of a source for at least five (5) years and shall be made available to the Commission or any members, employees or agents thereof, during regular business hours.

   (b) Sampling Ports

     (i) Any person owning or operating equipment shall, upon request of the Director, provide, in connection with each flue, a power source near the point of testing in addition to such sampling and testing facilities and sampling ports, including safe and easy access thereto, exclusive of instruments and sensing devices, as may be necessary for the Department to determine the nature and quality of emissions which are or may be discharged as a result of operations of the equipment served by the flue. Evidence and data based on these samples and calculations may be used to substantiate violations of the Act or the Regulations of the Plan. Agents of the Department shall be permitted to sample the stacks during operating hours.  

   (c) Filing of Emissions Data

     Upon request by the Director, any person affected by any Regulations of the Plan or by the Arkansas Air Pollution Control Code shall file emissions data with the Department on forms supplied by the Department.

   (d) Sampling Procedures and Terminology

     (i) Where not otherwise specified in Regulations of the Plan, and orders of the Commission, the procedures used for sampling air and measuring air contaminants, and the methods of expressing the findings shall be those commonly accepted and used in the field of air pollution control.

   (e) Continuous Monitoring

     (i) The person responsible for a stationary source included in a category listed in Appendix P of 40 CFR Part 51 (40 FR 46247, October 6, 1975) shall adhere to all applicable provisions of said Appendix P including the installation, calibration, maintenance and operation of equipment for continuously monitoring and recording emissions. On a case by case basis and within the stated limits of the referenced requirements, the Director may allow applicable exceptions which are requested and justified by the person responsible for an emission source.

     (ii) The Director may require the owner or operator of any air contaminant source to install, use, and maintain such monitoring equipment; sample such emissions in accordance with methods as the Director shall prescribe; establish and maintain such records; and make such periodic emission reports as required below.

   (f) Reporting General Process Information

     (i) The owner or operator of any equipment shall, upon request of the Director, supply such information, as the Director may reasonably require and as may be necessary, to determine the impact that the operation of such equipment has, or will have, on air quality levels. Such information shall be made on forms made available by the Department or in a format prescribed by the Director.

   (g) Reporting Emission Data

     (i) The owner or operator of any equipment shall, upon notification by the Director, maintain records of the nature and amount of emissions, to which an air quality control emission  regulation applies, from the source and any other information (in addition to that data required above) as may be deemed necessary by the Director to determine whether the source is in compliance with applicable regulations.

     (ii) The information recorded shall be summarized and reported to the Director, on forms furnished by the Director, and shall be submitted within 45 days after the end of the reporting period. Reporting periods are June 1 through November 30 and December 1 through May 31 or such other periods as the Director may specify. Information reported to the Director shall be signed by the person responsible for its accuracy.

     (iii) Emission data obtained by the Director shall be correlated with applicable emission limitations and other control measures and be made available to the public during normal business hours.
