The Tulalip Department of Environment, having regulatory authority over air quality within the exterior boundaries of the Tulalip Indian Reservation, adopts the following regulation to control the emission of air contaminants from all sources within the jurisdiction of the Department, to provide for the uniform administration and enforcement of this regulation, and to carry out the requirements and purposes of the Federal Clean Air Act.
The Tulalip Tribes is a Federally recognized Indian tribe organized pursuant to the Indian Reorganization Act of 1934, as amended, which is the successor in interest of the aboriginal Snohomish, Snoqualmie, Skykomish and other allied tribes and bands that were parties to the Treaty of Point Elliott.
(Ord. 96 § 1.01, 6-7-1997 (Res. 97-0118))
The name of the air pollution control agency shall be known and cited as the Tulalip Department of Environment.
(Ord. 96 § 1.03, 6-7-1997 (Res. 97-0118))
When used herein:
(1) 
“Acceptable source impact level (ASIL)”
means a concentration of a toxic air contaminant in the outdoor atmosphere in any area that does not have restricted or controlled public access that is used to evaluate the air quality impacts of a single source. There are three types of acceptable source impact levels: risk-based, threshold-based, and special. Concentrations for these three types of ASILs are established by the Board after public hearing and are listed in Appendix A, attached to the ordinance codified in this chapter.
(2) 
“Actual emissions”
means the average rate at which the source actually emitted air contaminants during the two-year period preceding a specific date, and which is representative of normal source operations. To account for unusual circumstances such as strikes, the Control Officer may approve or require the use of another time period that is more representative of normal operations than is the immediately preceding two-year period.
(3) 
“Adequate source of heat”
means the ability to maintain 70 degrees Fahrenheit at a point three feet above the floor in all normally inhabited areas of a dwelling.
(4) 
“Air contaminant”
means dust, fumes, mist, smoke, other particulate matter, vapor, gas, odorous substance, or any combination thereof.
(5) 
“Air pollution”
means the presence in the outdoor atmosphere of one or more air contaminants in sufficient quantities and of such characteristics and duration as is, or is likely to be, injurious to human health, plant or animal life, or property, or which unreasonably interferes with enjoyment of life and property.
(6) 
“Air pollution episode”
means a period when a forecast, alert, warning, or emergency air pollution stage is declared by the Tulalip Department of Environment.
(7) 
“Allowable emissions”
means the emission rate calculated using the maximum rated capacity of the source (unless the source is subject to a Federal enforcement permit that limits the operating rate, or hours of operation, or both) and the most stringent of the following:
(a) 
Any applicable standard under 40 CFR Parts 60, 61, and 63;
(b) 
Any applicable emission standard under this chapter;
(c) 
Any applicable emission standard specified in an order of approval or operating permit, including those with a further compliance date.
(8) 
“Ambient air”
means an established concentration, exposure time, and frequency of occurrence of an air contaminant in the ambient air that shall not be exceeded.
(9) 
“Ambient air quality standard”
means an established concentration, exposure time, and frequency of occurrence of an air contaminant in the ambient air that shall not be exceeded.
(10) 
“Best available control technology”
means technology that will result in an emission standard, including a visible emission standard, based on the maximum degree of reduction which the Department, on a case-by-case basis, taking into account energy, environmental, and economic impacts, and other costs, determines is achievable for such source through application of production processes, available methods, systems, and techniques, including fuel cleaning or treatment, clean fuels, or innovative fuel combustion techniques for control of each air contaminant. In no event shall application of the best available control technology result in emissions of any air contaminant that would exceed the emissions allowed by any applicable standard under 40 CFR Parts 60, 61, and 63. The Department may prescribe a design, equipment, work practice, or operational standard, or combination thereof, to meet the requirements of the best available control technology. Such standard shall, to the degree possible, set forth the emission reduction achievable by implementation of such design, equipment, work practice, or operation and shall provide for compliance by means that achieve equivalent results.

In determining whether the thresholds defining a major modification have been exceeded, the emissions permitted under orders of approval issued to the facility since the designation of nonattainment that were not major modifications, and all fugitive emission increases that can be reasonably qualified, shall be included. Any emission reduction credits banked by the facility since the designation is applied are then considered to have been used. For modifications of an individual piece of equipment, the baseline shall be the source’s actual emissions or allowable emissions, whichever is smaller. (Note: volatile organic compounds and nitrogen oxides are the air contaminants for which an area is designated nonattainment for ozone.)

In determining whether the threshold defining a major source has been exceeded, all fugitive emissions that can be reasonably quantified shall be included. Any emission reduction credits banked by the facility may be subtracted from this amount; provided, that any credits so applied are then considered to have been used.
(32) 
“Modification”
means any physical change in, or change in the method of operation of, a source, except an increase in the hours of operation or production rates (not otherwise prohibited) or the use of an alternative fuel or raw material that the source is approved to use under an order of approval or operating permit, that increases the amount of any air contaminant emitted or that results in the emission of any air contaminant not previously emitted.
(33)

Any physical or operational limitation on the capacity of the facility to emit an air contaminant, including control equipment and restrictions on the hours of operation or on the type or amount of material combusted, stored, or processed, shall be treated as part of its design only if the limitation or the effect it would have on emissions is Federally enforceable.
(42) 
“Reasonably available control technology”
means the lowest emission standard that a particular source or source category is capable of meeting by the application of control technology that is reasonably available considering technological and economic feasibility. Reasonably available control technology is determined on a case-by-case basis for an individual source or source category taking into account the impact of the source upon air quality, the availability of additional controls, the emission reduction to be achieved by additional controls, the impact of additional control or air quality, and the capital and operating costs of the additional controls.
