A. The control officer may require, by permit or order, any source of air contaminants to monitor, sample, or perform other studies to quantify emissions of air contaminants or levels of air pollution that may reasonably be attributable to that source if the control officer makes the written determinations required by either subsection B or subsection C of this section and if the control officer either:
1. Determines that monitoring, sampling, or other studies are necessary to determine the effects of the facility on levels of air pollution.
2. Has reasonable cause to believe a violation of this title or a permit issued pursuant to this title has been committed.
3. Determines that those studies or data are necessary to accomplish the purposes of this title, and that the monitoring, sampling, or other studies by the source are necessary in order to assess the impact of the source on the emissions of air contaminants.
B. The control officer shall, by permit or order, require sources of air contaminants for which ambient air quality standards or emission standards or design, equipment, work practice or operational standards have been adopted pursuant to A.R.S. 49-424 or A.R.S. 49-425, subsection A to monitor, sample, or otherwise quantify their emissions or air pollution which may reasonably be attributed to sources of such air contaminants if the control officer determines in writing that all of the following conditions are met:
1. The actual or potential emissions of air pollution may adversely affect public health or the environment; and
2. An adequate scientific basis for the monitoring, sampling, or quantification method exists; and
3. The monitoring, sampling, or quantification method is technically feasible for the subject contaminant and source; and
4. The monitoring, sampling, or quantification method is reasonably accurate; and
5. The cost of the method is reasonable in light of the use to be made of the data.
C. The Control Officer may, by permit or order, require sources of air contaminants not described by subsection B of this section to perform monitoring, sampling or other quantification of its emissions or air pollution that may reasonably be attributed to such source if the control officer determines in writing that all of the following conditions are met:
1. The actual or potential emissions of air pollution may adversely affect public health or the environment; and
2. An adequate scientific basis for the monitoring, sampling, or quantification method exists; and
3. The monitoring, sampling, or quantification method is technically feasible for the subject contaminant and source; and
4. The monitoring, sampling, or quantification method is reasonably accurate; and
5. The cost of the method is reasonable in light of the use to be made of the data.
D. Before requiring such monitoring, sampling, or other quantification by permit or order, the control officer shall consider the relative cost and accuracy of any alternatives which may be reasonable under the circumstances such as emission factors, modeling, mass balance analyses, or emissions projections.
E. Orders issued or permit conditions imposed pursuant to this section shall be appealable to the hearing board in the same manner as that prescribed for orders of abatement and permit conditions.
