Chapter 173-415 - Primary aluminum plants
Section 173-415-030 - Emission standards
Current through Register Vol. 24-06, March 15, 2024
(1) Fluoride.
(2) Particulate. Facilities shall reduce the total emission of particulate matter to the atmosphere from the reduction process (potlines) to the lowest level consistent with reasonably available control technology (RACT) for primary aluminum reduction plants. The emission of solid particulate shall not exceed 7.5 grams per kilogram (fifteen pounds per ton) of aluminum produced on a daily basis. Facilities shall calculate aluminum produced using the method in 40 C.F.R. 63.847(e)(6) used for determining aluminum production rate.
(3) Visible emissions. Visible emissions from any emissions unit in a primary aluminum reduction plant shall not exceed an average twenty percent opacity for more than six consecutive minutes in any sixty-minute period. This provision shall not apply:
(4) Fugitive emissions. Each primary aluminum reduction plant shall use RACT to prevent fugitive emissions. Fugitive dust is included in fugitive emissions.
(5) Sulfur dioxide.
(6) Operation and maintenance (O&M). At all times, including periods of abnormal operation and upset conditions, owners and operators shall, to the extent practicable, maintain and operate an affected facility, including associated air pollution control equipment, in a manner consistent with good air pollution control practice. Determination of whether acceptable operating and maintenance procedures are being used will be based on information available to ecology, which may include, but is not limited to, monitoring results, opacity observations, review of operating and maintenance procedures, and inspection of the source. The means for demonstrating ongoing compliance with good O&M may include, but not be limited to: More frequent source testing, prescriptive procedures or inspections, control values for emissions at values less than the applicable regulatory requirements and that function as an investigative trigger rather than as a limit, collection and efficiency requirements, or the use of CEMs.
(7) Source testing. To demonstrate compliance with this chapter, the testing provisions of chapters 173-400, 173-481 WAC and the requirements in 40 C.F.R. Part 63, Subpart LL shall be applicable.
(8) Alternative emission limitation. An owner or operator may request an alternative emission limitation (as defined in WAC 173-400-030 ) under:
