• | Update the list of toxic air pollutants. |
• | Recalculate: |
o | Acceptable source impact levels (ASIL). |
o | Small quantity emission rates (SQER). |
o | De 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." |
• | 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. |
• | 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. |
• | 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. |
• | Decision making documentation: Updating chapter 173-460 WAC, Controls for new sources of toxic air pollutants. |
• | Annotated table of proposed TAPs, ASILs, SQERs, and de minimis emission values (Excel spreadsheet). |
• | Rule-making stakeholder meeting materials. |
• | 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. |
• | 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. |
• | 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. |
• | 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. |
• | Update the TAP list. |
• | Recalculate: |
o | De minimis emission values. |
o | SQERs. |
o | ASILs. |
• | 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." |
• | Lack of sufficient scientific data to retain the chemical on the list. |
• | Chemical being redundant with other chemicals or chemical groups on the list. |
• | 5-Nitro-o-anisidine. |
• | Ammonium sulfate. |
• | Dibromochloromethane. |
• | Melphalan hydrochloride. |
• | Chromic acid. |
• | Chromium hexavalent: Soluble, except chromic trioxide. |
• | Pentabromodiphenyl ether. |
