# §62.14650. How do I conduct the initial and annual performance test?

- (a) All performance tests must consist of a minimum of three test runs conducted under conditions representative of normal operations.
- (b) You must document that the waste burned during the performance test is representative of the waste burned under normal operating conditions by maintaining a log of the quantity of waste burned (as required in [§ 62.14700(b)(1)](/cfr/40/62.14700.md?p=b-1)) and the types of waste burned during the performance test.
- (c) All performance tests must be conducted using the minimum run duration specified in Table 1 of this subpart.
- (d) Method 1 of [40 CFR part 60](/cfr/40/part60.md), appendix A must be used to select the sampling location and number of traverse points.
- (e) Method 3A or 3B of [40 CFR part 60](/cfr/40/part60.md), appendix A must be used for gas composition analysis, including measurement of oxygen concentration. Method 3A or 3B of [40 CFR part 60](/cfr/40/part60.md), appendix A must be used simultaneously with each method.
- (f) All pollutant concentrations, except for opacity, must be adjusted to 7 percent oxygen using Equation 1 of this section:
- (g) You must determine dioxins/furans toxic equivalency by following the procedures in [paragraphs (g)(1) through (3)](#g-1..g-3) of this section.
  - (1) Measure the concentration of each dioxin/furan tetra- through octa-congener emitted using EPA Method 23.
  - (2) For each dioxin/furan congener measured in accordance with [paragraph (g)(1)](#g-1) of this section, multiply the congener concentration by its corresponding toxic equivalency factor specified in Table 3 of this subpart.
  - (3) Sum the products calculated in accordance with [paragraph (g)(2)](#g-2) of this section to obtain the total concentration of dioxins/furans emitted in terms of toxic equivalency.
