EPA: National Emission Standards for Hazardous Air Pollutants: Wood Preserving Area Sources Technology Review; Technical Correction for Surface Coating of Wood Building Products

2023-03-08T06:00:00Z

SUMMARY: This action finalizes the technology review (TR) conducted for the Wood Preserving Area Sources category regulated under national emission standards for hazardous air pollutants (NESHAP). While the Environmental Protection Agency (EPA) is making no changes to the existing standards as a result of the TR, this action establishes minor editorial and formatting changes to the Wood Preserving Area Sources NESHAP table of applicable general provisions. In addition, the EPA is finalizing technical corrections to the Surface Coating of Wood Building Products NESHAP.

DATES: This final rule is effective on March 8, 2023, published in the Federal Register March 8, 2023, page14280 .

§63.4741 How do I demonstrate initial compliance with the emission limitations?

* * * *

(a)(1)(i) Count each organic HAP that is measured to be present at 0.1 percent by mass or more for OSHA-defined carcinogens as specified in 29 CFR 1910.1200(d)(4), and at 1.0 percent by mass or more for other organic HAP compounds. For example, if toluene (not an OSHA carcinogen) is measured to be 0.5 percent of the material by mass, you do not have to count it. Express the mass fraction of each organic HAP you count as a value truncated to four places after the decimal point (e.g., 0.379178412 truncates to 0.3791).

* * * *

(a)(4) Information from the supplier or manufacturer of the material. You may rely on information other than that generated by the test methods specified in paragraphs (a)(1) through (3) of this section, such as manufacturer's formulation data, if it represents each organic HAP that is present at 0.1 percent by mass or more for OSHA-defined carcinogens as specified in 29 CFR 1910.1200(d)(4), and at 1.0 percent by mass or more for other organic HAP compounds. For example, if toluene (not an OSHA carcinogen) is 0.5 percent of the material by mass, you do not have to count it. If there is a disagreement between such information and results of a test conducted according to paragraphs (a)(1) through (3) of this section, then the test method results will take precedence unless, after consultation, a regulated source could demonstrate to the satisfaction of the enforcement agency that the formulation data were correct.
