The owner may apply to the board for approval under 40 CFR 60.8(b) to use a reference method with minor changes in methodology, use an equivalent method, use an alterna tive method the results of which the board has determined are adequate for demonstrating compliance, waive the requirement for an emission test because the owner has demonstrated compliance by other means, or use a shorter sampling time or smaller sampling volume. E. Alternative emission testing schedules may be established as follows.
1. A Class II unit that has conducted emission tests for dioxins/furans, cadmium , lead, mercury , particulate matter, opacity, hydrogen chloride , and fugitive ash over three consecutive years, andhas demonstrated compliance with the emission limits is not required to conduct an emission test

for that pollutant for the next two years. An emission test shall be conducted within 36 months of the anniversary date of the third co nsecutive emission test that shows compliance with the emission limit. Thereafter, emission tests shall be performed every third year but no later than 36 months following the previous emission tests. If an emission test shows noncompliance with an emissio n limit, annual emission tests for that pollutant shall be conducted until all emission tests over three consecutive years show compliance with the emission limit for that pollutant. 2. An alternative test schedule for dioxins/furans emissions may be esta blished if the following criteria are met: (i) the affected facility contains multiple municipal waste combustion units onsite that are subject to this article; and (ii) those municipal waste combustion units have demonstrated levels of dioxins/furans emis sions less than or equal to 15 nanograms per dry standard cubic meter (total mass) for Class I units, or 30 nanograms per dry standard cubic meter (total mass) for Class II units, for two consecutive years. If these criteria are met, annual emission tests shall be conducted on only one municipal waste combustion unit per year. emission tests conducted under the provisions of this subdivision shall be conducted as follows. a. The annual emission test shall be conducted no more than 13 months following an em ission test on any municipal waste combustion unit subject to this article. Each year a different municipal waste combustion unit subject to this article shall be tested. All municipal waste combustion units subject to this article shall be tested in a seq uence determined by the owner. Once a testing sequence has been determined it shall not be changed without approval of the
board. b. If each annual emission test shows levels of dioxins/furans emissions less than or equal to 15 nanograms per dry standard cubic meter (total mass) for Class I units, or 30 nanograms per dry standard cubic meter (total mass) for Class II units, emission tests may be conducted on only one municipal waste combustion unit subject to this article per year. c. If any annual emission test indicates levels of dioxins/furans emissions greater than 15nanograms per dry standard cubic meter (total mass) for Class I units, or 30 nanograms per dry

standard cubic meter (total mass) for Class II units, subsequent annu al emission tests shall be conducted on all municipal waste combustion units subject to this article. The owner may return to testing one municipal waste combustion unit subject to this article per year if it can demonstrate dioxins/furans emissions levels less than or equal to 15 nanograms per dry standard cubic meter (total mass) for Class I units, or 30 nanograms per dry standard cubic meter (total mass) for Class II units, for all municipal waste combustion units at a stationary source subject to this a rticle for two consecutive years.
