PERMANENT RULES
DEPARTMENT OF ECOLOGY
[Order 18-07—Filed November 22, 2019, 1:59 p.m., effective December 23, 2019]
Effective Date of Rule: Thirty-one days after filing.
Purpose: Chapter 173-460 WAC, Controls for new sources of toxic air pollutants, this rule includes air quality permitting requirements for businesses that emit toxic air pollutants.
The amendments:
Update the list of toxic air pollutants.
Recalculate:
ºAcceptable source impact levels (ASIL).
ºSmall quantity emission rates (SQER).
ºDe minimis emission values.
Specify the number of significant digits of emissions rates (i.e., de minimis and SQERs) and concentrations (i.e., ASILs).
Update language in the rule to use the acronym "TAP" instead of "toxic air pollutant."
Citation of Rules Affected by this Order: Amending WAC 173-460-040, 173-460-080, and 173-460-150.
Statutory Authority for Adoption: Chapter 70.94 RCW, Washington Clean Air Act.
Other Authority: Not applicable.
Adopted under notice filed as WSR 19-12-092 on June 4, 2019.
Changes Other than Editing from Proposed to Adopted Version: WAC 173-460-150, changes throughout table.
Common names and order of toxic air pollutants, we edited the names and order of chemicals to make it easier to find them in the table. The new system groups chemical families near each other instead of throughout the table.
Scientific notation, we simplified the table by providing all emission threshold values in the scientific notation format (1.0E+00). Displaying ASILs, SQERs, and de minimis emission values in the table in two formats – decimal and scientific notation – was confusing.
WAC 173-460-150, pollutant specific changes.
Asbestos, the amendments add six types of asbestos to the list of toxic air pollutants: Actinolite, Amosite, Anthophylite, Chrysotile, Crocidolite, and Tremolite. Each of these has its own unique CAS number. The ASILs, SQERs, and de minimis emissions levels are identical to those of the general listing for "Asbestos (fibers/cubic centimeter)." This change should reduce confusion about the coverage of the existing asbestos group listing.
Cobalt, we added "and compounds, NOS" to clarify that all forms of cobalt compounds are equally toxic based on the mass of cobalt in a cobalt compound.
Dimethyl mercury, we retained the original listing of "dimethyl mercury" because we mistakenly changed the name to "methyl mercury (dimethyl mercury)" when we proposed the rule.
Ethyl carbamate, we added urethane as a common name for this chemical because it has the same CAS number.
Fluorides, we corrected the misspelling of fluoride in the common name of this pollutant.
Libby amphibole asbestos, we corrected the misspelling of amphibole and added "and amphibole, NOS" to be more expansive and protect public health. This was due to EPA's toxicological review of Libby amphibole asbestos that highlights concerns about a variety of amphiboles.
Nickel carbonate hydroxide, we corrected the CAS number to 12607-70-4.
Nickel oxide, we added nickel monoxide and nickel(II) oxide as common names for nickel oxide because they have the same CAS number.
Nickel oxide black, we added CAS 1314-06-3 for this pollutant because the rule did not include one. We added nickel sesquioxide and nickel(III) oxide as common names for nickel oxide black because they have the same CAS number.
Sulfur trioxide, we corrected the CAS number to 7446-11-9.

AMENDATORY SECTION(Amending WSR 09-11-131, filed 5/20/09, effective 6/20/09)
WAC 173-460-040New source review.
(1) Applicability and exemptions. This chapter supplements the new source review requirements of WAC 173-400-110 by adding review requirements for new and modified toxic air pollutant sources. An action that is exempt from new source review under WAC 173-400-110 (4) or (5) is exempt under this chapter as well, except that a local air authority may adopt its own list of exemptions in accordance with RCW 70.94.331 (2)(b) to operate in lieu of or in addition to the exemptions in WAC 173-400-110 (4) and (5). An action that requires a notice of construction application under WAC 173-400-110 is subject to the review requirements of this chapter, unless the emissions before control equipment of each ((toxic air pollutant))TAP (rounded to two significant digits) from a new source or the increase in emissions from each modification is less than the applicable de minimis emission threshold for that TAP listed in WAC 173-460-150.
(2) New source review of a modification is limited to the emission unit or units proposed to be modified and the TAPs whose emissions would increase as a result of the modification.
(3) The permitting authority that is reviewing a notice of construction application for a new or modified toxic air pollutant source must ensure that:
(a) The new or modified emission units use tBACT for emissions control for the ((toxic air pollutants))TAPs with emission increases that trigger the need to submit a notice of construction application; and
(b) The new or modified emission units comply with WAC 173-460-070 as demonstrated by using the procedures established in WAC 173-460-080 or, failing that, demonstrates compliance by using the additional procedures in WAC 173-460-090 and/or 173-460-100.
AMENDATORY SECTION(Amending WSR 09-11-131, filed 5/20/09, effective 6/20/09)
WAC 173-460-080First tier review.
(1) A notice of construction application for a new or modified toxic air pollutant source must include an acceptable source impact level analysis for each TAP emitted by the new or modified emission units with an emission increase greater than the de minimis emission level specified in WAC 173-460-150. The permitting authority may complete this analysis.
(2) The acceptable source impact analysis requirement of WAC 173-460-070 can be satisfied for any TAP using either dispersion modeling or the small quantity emission rate.
(a) Dispersion modeling. The applicant who relies on dispersion modeling must model the increase in the emissions of each TAP emitted by the new or modified emission units, after application of tBACT. The notice of construction application must demonstrate that the modeled ambient impact (rounded to two significant digits) of the aggregate emissions increase of each TAP does not exceed the ASIL for that TAP as listed in WAC 173-460-150. If concentrations predicted by dispersion screening models exceed applicable acceptable source impact levels, more refined modeling and/or emission techniques must be used. Refined modeling techniques must be approved by the permitting authority.
(b) Small quantity emission rates. An applicant may show for any TAP that the increase in emissions of that TAP (rounded to two significant digits), after application of tBACT, is less than the small quantity emission rate listed for that TAP in WAC 173-460-150.
(3) Reduction of TAPs from existing emission units. An applicant may include in ((a))an acceptable source impact analysis proposed reductions in actual emissions of a particular TAP from emission units at the source that are not new or modified for the purpose of offsetting emissions of that TAP caused by the new or modified source. The reductions in TAP emissions authorized by this subsection must be included in the approval order as enforceable emission limits and must meet all the requirements of WAC 173-460-071.
(4) Decision criteria.
(a) If the permitting authority finds that the modeled impact of the increase in emissions of a TAP from the new or modified emission units does not exceed the ASIL for that TAP then the authority may approve the notice of construction application.
(b) If the permitting authority finds that the modeled impact of the increase in emissions of a TAP from the new or modified emission units exceeds the ASIL for that TAP then the permitting authority may not approve the project. The applicant may file a second tier review application in compliance with WAC 173-460-090.
