N.M. Code R. § 20.2.72.213
Within sixty (60) days after achieving the maximum production rate at which the source will be operated but not later than one hundred eighty (180) days after initial startup of the source, the owner or operator of the source may be required to conduct a performance test. The test method utilized shall be approved by the Department. Whenever the requirements of 40 CFR 60 or 61 apply, test methods must be utilized as specified in those regulations. The owner or operator shall notify the Department at least thirty (30) days prior to the test date and allow a representative of the Department to be present at the test. A written report of the results of the test shall be submitted to the Department by the owner or operator within thirty (30) days from the test date. This requirement may be reimposed on a source as necessary if inspections of the source indicate noncompliance with permit conditions subject to such testing, or the previous test showed noncompliance or was technically unsatisfactory. In such cases, the test requirement may be reimposed as frequently as necessary until compliance is achieved and testing is performed in a technically satisfactory manner. This testing requirement may be waived if the source is a member of a class subject to an exemption from this requirement pursuant to 20.2.72.214 NMAC, and has agreed to comply with, and its permit contains, enforceable design, operational and locational protocols set by the Department for the class of sources to which the source belongs.
