Purpose of the Proposal and Its Anticipated Effects, Including Any Changes in Existing Rules: The proposed amendments make the following changes:
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."
Anticipated effects include:
Increased modeling or health impact analysis when a new project emits a new toxic air pollutant. A project may be subject to increased pollution controls (toxics-BACT) and may need to include additional emission controls.
More stringent values could result in more emissions analysis and review.
Less stringent values could result in no emissions analysis and review. Projects at Hanford will likely benefit from the reduced stringency of the methyl mercury ASIL.
No modeling or health impact analysis for a project with any of the four removed chemicals.
Added protection for the public from the new pollutants and more protective up-to-date threshold values.
Reasons Supporting Proposal: The reasons for the proposed rule amendments are to:
Align the rule with current scientific information about chemicals, including adjusting for the impacts of early life exposure to a chemical. We are proposing to add some chemicals or modified values based on previous errors in the rule language itself.
Remove ammonium sulfate as a toxic air pollutant based on our toxicity review in response to a rule-making petition on this chemical from the Far West Agribusiness Association.
Improve clarity.
Remove redundancy.
The "Decision Making Documentation: Updating Chapter 173-460 WAC" provides the decisions and reasons supporting the proposal for the following topics:
Updating the list (add or subtract chemicals): Retained three hundred eighty-seven TAPs, removed eight TAPs, and added forty-five TAPs.
Chemicals considered but not added to the TAP list: Seven (acetone, fuel oil no. 2, keronsene [kerosene] and four kerosene-based jet fuels).
Evaluation of ammonium sulfate: Removed.
Recalculation of ASILs: Updated.
Evaluation of excluding criteria pollutants as TAPs: Retained as TAPs.
Evaluation of the use of early life adjustment factors: Included so adjusted appropriate ASILs.
Review of the existing ASIL for diethyl and methyl mercury: Revised.
Evaluation of ASILs for groups of chemicals (toxicity equivalency): No adjustments.
Revision of the small quantity emission rate modeling parameters: Updated modeling parameters.
Recalculation of the small quantity emission rates: Recalulated [Recalculated] using AERSCREEN model and new modeling parameters.
Recalculation of de minimis emission values: Updated using existing methodology (SQER/20).
Updating the rule to support the rule changes: Aligned rule to require two significant digits for emission rates and concentrations.

Agency Comments or Recommendations, if any, as to Statutory Language, Implementation, Enforcement, and Fiscal Matters: If we adopt this proposal, we will write a rule implementation plan as part of the information we share when we announce the adoption. The purpose of this plan is to inform those who must comply with chapter 173-460 WAC about how we intend to:
Implement and enforce the rule.
Inform and educate persons affected by the rule.
Promote and assist voluntary compliance for the rule.
Evaluate the rule.
Train and inform ecology staff about the new or amended rule.
Also included in this plan is information about:
Supporting documents that may need to be written or revised because of the new rule or amended rule.
Other resources where more information about the rule is available.
Contact information for ecology employees who can answer questions about the rule implementation.
We intend to update or develop the following supporting materials:
Update "Guidance Document: First, Second, and Third Tier Review of Toxic Air Pollution Sources" publication number 08-02-025.
Clarify that the mass of a specific metal in a compound should be compared to the specific metal ASIL instead of comparing the mass of the entire compound to the metal ASIL.
Clarify that increased emissions of multiple metal compounds (e.g., Chromium VI) should be summed and compared to the broad ASIL instead of individually for each compound for which an ASIL exists. For example, if a source emits barium chromate, lithium chromate, and strontium chromate, the total chromium VI mass or ambient impact of hexavalent chromium in these compounds must be calculated and compared to the "Chromium (VI) & compounds, NOS" SQER or ASIL.
Post a searchable spreadsheet of the TAPs table in WAC 173-460-150 on the "Health impact review of toxic air pollution" web page.
Please provide comments on other guidance materials or other suggestions that could assist in implementing this rule.

The proposed rule does impose more-than-minor costs on businesses.
This small business economic impact statement (SBEIS) presents the:
(1) Compliance requirements of the proposed rule.
(2) Results of the analysis of relative compliance cost burden.
(3) Consideration of lost sales or revenue.
(4) Cost-mitigating action taken by ecology, if required.
(5) Small business and local government consultation.
(6) Industries likely impacted by the proposed rule.
(7) Expected net impact on jobs statewide.
A small business is defined by the Regulatory Fairness Act (chapter 19.85 RCW) as having fifty or fewer employees. Estimated costs are determined as compared to the existing regulatory environment, the regulations in the absence of the rule. The SBEIS only considers costs to "businesses in an industry" in Washington state. This means that impacts, for this document, are not evaluated for nonprofit or government agencies.
The existing regulatory environment is called the "baseline" in this document. It includes only existing laws and rules at federal and state levels.
This information is excerpted from ecology's complete set of regulatory analyses of the proposed rule. For complete discussion of the likely costs, benefits, minimum compliance burden, and relative burden on small businesses, see the regulatory analyses (Ecology publication no. 19-02-012, June 2019).
COMPLIANCE REQUIREMENTS OF THE PROPOSED RULE, INCLUDING PROFESSIONAL SERVICES: The baseline for our analyses generally consists of existing rules and laws, and their requirements. This is what allows us to make a consistent comparison between the state of the world with and without the proposed amendments.
For this proposed rule making, the baseline includes:
The existing rule, chapter 173-460 WAC, Controls for new sources of toxic air pollutants.
The authorizing statute, chapter 70.94 RCW, Washington Clean Air Act.
The proposed amendments:
Update the TAP list.
Recalculate:
oDe minimis emission values.
oSQERs.
oASILs.
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."
1. Update the TAP list.
Baseline: The baseline rule contains three hundred ninety-five TAPs.
Proposed: The proposed amendments remove and add chemicals to the list of TAPs.
Removing chemicals from the TAP list: We are proposing to remove eight TAPs from the baseline TAP list. We are basing these amendments on the:
Lack of sufficient scientific data to retain the chemical on the list.
Chemical being redundant with other chemicals or chemical groups on the list.
Adding chemicals to the TAP list: We are proposing to add forty-five chemicals to the baseline TAP list. We are basing these amendments on current scientific information sufficient to identify the chemical as a TAP. We then set an appropriate ASIL, SQER, and de minimis emission value for it.
Expected impact:
Removing chemicals from the TAP list: New or modified facilities emitting four of the chemicals we are proposing to remove from the TAP list would potentially be required to do less modeling or health impact analysis as part of permit application if their emissions exceed the baseline SQER. If emissions of these chemicals exceed baseline ASILs, they could be able to reduce the amount of preplanned emissions controls:
5-Nitro-o-anisidine.
Ammonium sulfate.
Dibromochloromethane.
Melphalan hydrochloride.
New or modified facilities emitting these four chemicals will notice no change because emissions from those chemicals are subject to another TAP:
Chromic acid.
Chromium hexavalent: Soluble, except chromic trioxide.
Pentabromodiphenyl ether.
Tetrabromodiphenyl ether.
If a permitting agency permits a facility under the baseline and they exceed only the baseline de minimis levels for removed TAPs, the facility could become exempt from permitting (all TAP emissions below de minimis).
Adding new chemicals to the TAP list: New or modified facilities emitting the chemicals we propose to add to the [list] as TAPs would potentially be required to do additional modeling or health impact analysis as part of a permit application. This occurs if their emissions of those chemicals exceed proposed de minimis emission values or SQERs. If emissions of these chemicals exceed proposed ASILs, they would need to preplan additional emissions controls or submit a health impact assessment under second tier review.
If the baseline does not require facilities to do additional analysis (because they do not emit baseline TAPs in excess of de minimis levels), they would need to do additional analysis if they emit a proposed new TAP in excess of the de minimis level.
The public also benefits from added protection from the proposed new TAPs. They are based on up-to-date scientific values and better reflect their true toxicity.
2. Recalculate de minimis emission values.
Baseline: The baseline rule includes de minimis emission values for three hundred ninety-five TAPs. New or modified facilities emitting below these levels are not subject to additional emissions analysis (first tier review review).
Proposed: The proposed amendments would modify de minimis emission values for four hundred twenty-eight TAPs (including the new and removed TAPs; see section 2.3.1). 0.5 percent of de minimis values increase (become less stringent), while 99.5 percent decrease (become more stringent).
We note that one percent of de minimis levels change the number of significant figures to which facilities report and compare emissions in a permit application. While rounding to the appropriate number of significant figures can numerically change the de minimis level, facilities round reported emissions in the same way. The comparison between de minimis levels and reported emissions is therefore unchanged.
Expected impact: Increasing de minimis values would result in reduced emissions analysis and review for these TAPs if they emit them. If these were the only TAPs they emit, they would not need the first tier review at all.
Decreasing de minimis values would result in more emissions analysis and review for those TAPs if they emit them. If these were the only TAPs they emit, they would need the first tier review that they would not need under the baseline.
Decreasing de minimis values also better protects the public. We base them on up-to-date scientific values that better reflect their true toxicity. This indicates the baseline under-protects public health compared to the proposed amendments.
3. Recalculate small quantity emission rates.
Baseline: The baseline rule includes SQERs for three hundred ninety-five TAPs. New or modified facilities emitting above these levels are subject to more complex dispersion modeling or additional analysis when emissions exceed ASILs (second tier review review).
Proposed: The proposed amendments would modify SQERs for four hundred thirty-two TAP (including the new and removed TAPs; see section 2.3.1). About 0.5 percent of SQERs increase (become less stringent), while 99.5 percent decrease (become more stringent).
Expected impact: SQERs increasing could result in facilities needing less emissions modeling for these TAPs, if they emit them. For TAPs with lower or new SQERs under the proposed amendments, this could result in a larger number of TAPs for which additional emissions modeling is required (or operational changes to reduce emissions below the SQER).
The public also benefits from added protection from the TAPs with decreasing SQERs. We base them on up-to-date scientific values that better reflect current dispersion modeling techniques. This indicates the baseline may in some cases under-protect public health compared to the proposed amendments.
4. Recalculate acceptable source impact levels.
Baseline: The baseline rule includes ASILs for three hundred ninety-five TAPs. New or modified facilities may not emit above these levels, and so preplan additional emissions controls.
Proposed: The proposed amendments would modify ASILs for one hundred fifty TAPs (including new and removed TAPs). About sixteen percent of ASILs would increase (become less stringent), and eighteen percent would decrease (become more stringent). ASILs for sixty-six percent of TAPs would not change under the proposed amendments.
Proposed amendments to acceptable source impact levels:

Includes four removed TAPs not covered by another listed TAP.
Expected impact: Higher ASILs could result in facilities not needing to preplan as many emissions controls (plan for emissions control or other measures) as under the baseline. Lower ASILs could mean they incur second tier review costs, or need to preplan for additional controls, if they emit the TAPs for which ASILs would change under the proposed amendments.
The public also benefits from added protection from the TAPs with decreasing ASILs. We base them on up-to-date scientific values that better reflect current understanding of toxicity, instead of the information supporting their baseline SQERs. This indicates the baseline under-protects (eighteen percent of TAPs) or over-protects (sixteen percent of TAPs) public health compared to the proposed amendments.
5. Specify the number of significant digits.
Baseline: The existing rule varies in the number of significant digits used for emissions rates and concentrations.
Proposed: The proposed amendments round all values to two significant digits.
Expected impact: We do not expect this proposed amendment to result in costs or benefits other than clarity. Since values are rounded, this amendment would not change exceedances of de minimis emission values, SQERs, or ASILs.
6. Use "TAP" acronym.
Baseline: We use the term "toxic air pollutant" throughout the existing rule.
Proposed: We replace the term "toxic air pollutant" with "TAP."
Expected impact: We do not expect this proposed amendment to result in costs or benefits other than clarity through conciseness.
COSTS OF COMPLIANCE: EQUIPMENT.
Compliance with the proposed amendments, compared to the baseline, is not likely to impose additional costs of equipment.
COSTS OF COMPLIANCE: SUPPLIES.
Compliance with the proposed amendments, compared to the baseline, is not likely to impose additional costs of supplies.
COSTS OF COMPLIANCE: LABOR.
Compliance with the proposed amendments, compared to the baseline, is not likely to impose additional costs of labor.
COSTS OF COMPLIANCE: PROFESSIONAL SERVICES.
Potential first tier review, TBACT, and permitting costs for unidentified facilities emitting added TAPs.
Recalculated de minimis emission values:
Annual cost of between $4 thousand and $38 thousand across five identified facilities. The equivalent present value is $61 thousand to $638 thousand.
Potential first tier review, TBACT, and permitting costs for unidentified facilities emitting TAPs above a proposed more stringent de minimis value.
Recalculated SQERs:
Annual cost of $380 thousand for additional emissions modeling across fifty-three facilities. The equivalent present value is $6.5 million over twenty years.
Potential additional costs of up to $3.6 million over twenty years for analysis of two TAPs for which averaging periods would change.
Potential second tier review costs for unidentified facilities emitting TAPs above a proposed more stringent SQER.
Recalculated ASILs:
Annual cost of up to $481 thousand for complex modeling and health impact assessment across fifty three facilities. The equivalent present value is $8.2 million over twenty years.
Potential second tier review costs for unidentified facilities emitting TAPs above a proposed more stringent ASIL.
COSTS OF COMPLIANCE: ADMINISTRATIVE COSTS.
Where applicable, ecology estimates administrative costs ("overhead") as part of the cost of labor and professional services, above.
COSTS OF COMPLIANCE: OTHER.
Not applicable.
COMPARISON OF COMPLIANCE COST FOR SMALL VERSUS LARGE BUSINESSES.
We calculated the estimated per-entity costs to comply with the proposed amendments, based on the primary compliance costs estimated in Chapter 3, and the primary compliance cost savings estimated in Chapter 4. In this section, we summarize compliance cost per employee at affected businesses of different sizes.
The average affected small business likely to be covered by the proposed amendments employs about eight people. (Database of Washington employment. Where ranges of employment were provided, we used the lowest number of employees in the range.) The largest ten percent of affected businesses employ an average of ten thousand five hundred people. (Ibid. Note that the primary employment database lists highest-employment businesses as 10,000+. The actual average for the largest ten percent of businesses is likely higher. This would make the disproportions shown in Table 7 larger.) Based on cost estimates from Chapter 3, we estimated the following compliance costs per employee. Some existing private employers potentially experience a net benefit, through avoided second tier review costs or reductions in preplanned emissions control equipment. Negative low net cost indicates a potential reduction in compliance costs.
Change in compliance costs per employee for small and large businesses:
Small Businesses
Largest Ten Percent of Businesses
Low
High
Low
High
($5,500.00)
$19,000.00
($5.50)
$5.00
While cost savings per employee are disproportionately larger for small businesses when a cost-savings is experienced, compliance costs are disproportionately higher for small businesses when net compliance costs are positive. We conclude that the proposed amendments are likely to have disproportionate impacts on some small businesses, and therefore must include elements in the proposed amendments to mitigate this disproportion, as far as is legal and feasible.
CONSIDERATION OF LOST SALES OR REVENUE.
Businesses that would incur costs could experience reduced sales or revenues if the changes would significantly affect the prices of the goods they sell. The degree to which this could happen is strongly related to each business's production and pricing model (whether additional lump-sum costs significantly affect marginal costs), as well as the specific attributes of the markets in which they sell goods, including the degree of influence of each firm on market prices, and the relative responsiveness of market demand to price changes.
We used the REMI PI+ model for Washington state to estimate the impact of the proposed amendments on directly affected markets, accounting for dynamic adjustments throughout the economy. The model accounts for interindustry impacts; price, wage, and population changes; and dynamic adjustment of all economic variables over time.
For existing facilities (representing potential future facilities in each year), we identified the associated industry. (See https://www.census.gov/eos/www/naics/index.html for more North American Industry Classification System (NAICS) information, industry groupings, and descriptions.) For preconstruction permits for which we did not have corresponding emissions data that was comparable with the baseline and proposed amendments, we assumed costs and benefits estimated for modeled facilities were distributed across identified industries in the same proportions as in facilities on which we had comprehensive emissions data. Net compliance costs (positive or negative) were assumed to be transfers to/from environmental consultants (NAICS 5413, Engineering Services, including environmental engineering services).
The REMI PI+ model output represents many aspects of the state economy, modeling the impact of positive and negative transfers across industries, and comparing it to a baseline model reflecting the status quo and forecast trends. To examine whether businesses were likely to lose sales or revenue, we looked at model output related to prices and demand (sales reflected in dollars). While the aggregate net increase in economic activity would create a very small increase in statewide (all industry) total demand (less than 1/100 of one percent), none of the industries we identified as incurring net compliance costs or experiencing net compliance benefits were found to experience a significant change in demand. Similarly, the model indicated that there would be no significant impacts to commodity prices or the overall price level. We therefore do not expect businesses to experience a significant impact to their sales and revenue.
MITIGATION OF DISPROPORTIONATE IMPACT.
RFA (RCW 19.85.030(2)) states that: Based upon the extent of disproportionate impact on small business identified in the statement prepared under RCW 19.85.040, the agency shall, where legal and feasible in meeting the stated objectives of the statutes upon which the rule is based, reduce the costs imposed by the rule on small businesses. The agency must consider, without limitation, each of the following methods of reducing the impact of the proposed rule on small businesses:
(a) Reducing, modifying, or eliminating substantive regulatory requirements;
(b) Simplifying, reducing, or eliminating recordkeeping and reporting requirements;
(c) Reducing the frequency of inspections;
(d) Delaying compliance timetables;
(e) Reducing or modifying fine schedules for noncompliance; or
(f) Any other mitigation techniques including those suggested by small businesses or small business advocates.
We considered all of the above options, and included the following legal and feasible elements in the proposed amendments that reduce costs. In addition, we considered the alternative amendment contents discussed in Chapter 6, and excluded those elements that would have imposed excess compliance burden on businesses:
Adding steps to address mixtures of TAPs.
Using more protective parameters to establish SQERs.
Maintaining the baseline de minimis, SQER, and ASIL values for methyl and diethyl mercury.
Adding acetone as a TAP.
Adding certain fuels as TAPs.
Because the purpose of this rule making is to update the basis of preconstruction permitting to current scientific values and understanding of toxicity, it is otherwise difficult to reduce compliance costs stemming from the proposed amendments. Moreover, it is difficult to reduce compliance costs specifically for small businesses, since there is not necessarily a correlation between business size and the types or amounts/rates of TAPs they emit. If review of new or modified facilities was reduced below what is deemed necessary based on current evidence regarding the toxicity of TAPs, for small businesses, the rule would not be able to meet the goal of protecting public health and the environment in the authorizing statute.
SMALL BUSINESS AND LOCAL GOVERNMENT CONSULTATION.
Ecology involved small businesses and local government in its development of the proposed amendments by:
Holding public meetings including representatives from:
oBusiness associations (typically representing many small businesses).
oConsultants.
oLocal air agencies.
oLocal governments (city, county).
oFederal agencies.
oEnvironmental groups.
oMembers of the public.
Communicating through the air quality program distribution list, including:
oForty-six representatives from government agencies (excluding ecology).
oSixteen representatives from local air agencies.
oTwelve representatives from organizations representing industry.
oFour representatives from local governments.
oNinety-three direct representatives of industry.
oForty consultant representatives.
Communicating through the distribution list created for this rule making, including:
oFourteen representatives from government agencies (excluding ecology).
oEleven representatives from local air agencies.
oTwo representatives from organizations representing industry.
oEleven direct representatives of industry.
oFive consultant representatives.
We note that it is time consuming and costly to participate in the rule-making process, and this can be a significant effort to small businesses. However, we did consult with them through organizations representing broader industries.

IMPACT ON JOBS.
We used the REMI PI+ model for Washington state to estimate the impact of the proposed amendments on jobs in the state, accounting for dynamic adjustments throughout the economy. The model accounts for inter-industry impacts; price, wage, and population changes; and dynamic adjustment of all economic variables over time. The proposed amendments would result in transfers of money within and between industries. We based model inputs on forecast quantifiable costs and benefits (cost-savings) estimated in Chapters 3 and 4.
For existing facilities (representing potential future facilities in each year), we identified the associated industry (see NAICS list in section 7.6). See https://www.census.gov/eos/www/naics/index.html for more NAICS information, industry groupings, and descriptions. For preconstruction permits for which we did not have corresponding emissions data that was comparable with the baseline and proposed amendments, we assumed costs and benefits estimated for modeled facilities were distributed across identified industries in the same proportions as in facilities on which we had comprehensive emissions data. Net compliance costs (positive or negative) were assumed to be transfers to/from environmental consultants (NAICS 5413, Engineering Services, including environmental engineering services).
The REMI PI+ model output represents many aspects of the state economy, modeling the impact of positive and negative transfers across industries, and comparing it to a baseline model reflecting the status quo and forecast trends. To examine the proposed amendments' impact on jobs, we looked at the aggregate jobs impact (across all industries and jobs in the state), as well as job impacts specific to industries directly impacted by the proposed amendments, and the industry of consultants that receive increases in emissions analysis spending, or lose income when emissions analysis spending is reduced or avoided. Since job impacts vary by year (as the state economy adjusts to a change in expenditures), the table below summarizes low and high impacts to jobs.

(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.
