Measurement of emissions of air contaminants

1. Sampling and testing. The department may reasonably require any person responsible for emission of air contaminants to make or have made tests, at a reasonable time or interval, to determine the emission of air contaminants from any source, for the purpose of determining whether the person is in violation of any standard under this article or to satisfy other requirements under the North Dakota Century Code chapter 23.1-06. All tests shall be made and the results calculated in accordance with test procedures approved or specified by the department. All tests shall be conducted by reputable, qualified personnel. The department shall be given a copy of the test results in writing and signed by the person responsible for the tests. The owner or operator of a source shall notify the department using forms supplied by the department, or its equivalent, at least thirty calendar days in advance of any tests of emissions of air contaminants required by the department. Advanced notification for all other testing will be consistent with the requirements of the appropriate regulations but in no case will be less than thirty calendar days. If the owner or operator of a source is unable to conduct the performance test on the scheduled date, the owner or operator of a source shall notify the department as soon as practicable when conditions warrant and shall coordinate a new test date with the department. Failure to give the proper notification may prevent the department from observing the test. If the department is unable to observe the test because of improper notification, the test results may be rejected. 2. The department may make tests. The department may conduct tests of emissions of air contaminants from any source. Upon request of the department, the person responsible for the source to be tested shall provide necessary holes in stacks or ducts and such other safe and proper sampling and testing facilities, exclusive of instruments and sensing devices as may be necessary for proper determination of the emission of air contaminants.
