AMENDATORY SECTION

SECTION 200 - DEFINITIONS

     ACTUAL EMISSIONS - The actual rate of emissions of a pollutant from an emission unit, as determined in accordance with a) through c) of this definition.

     a) In general, the actual emissions as of a particular date shall equal the average rate, in tons per year, at which the emissions unit actually emitted the pollutant during a two-year period which precedes the particular date and which is representative of normal stationary source operation. The NWCAA shall allow the use of a different time period upon a determination by the NWCAA that it is more representative of normal stationary source operation. Actual emissions shall be calculated using the emissions unit's actual operating hours, production rates, and types of materials processed, stored, or combusted during the selected time period.

     b) The NWCAA may presume that stationary source-specific allowable emissions for the unit are equivalent to the actual emissions of the emissions unit.

     c) For any emissions unit which has not begun normal operations on the particular date, actual emissions shall equal the potential to emit of the emissions unit on that date.

     ADVERSE IMPACT ON VISIBILITY - Adverse impact on visibility is defined in WAC 173-400-117.

     AIR CONTAMINANT - Dust, fumes, mist, smoke, other particulate matter, vapor gas, odorous substance, or any combination thereof. "Air pollutant" means the same as "air contaminant."

     AIR POLLUTION - 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 interfere with enjoyment of life and property. For the purposes of this regulation, air pollution shall not include air contaminants emitted in compliance with chapter 17.21 RCW, the Washington Pesticide Application Act, which regulates the application and control of the use of various pesticides.

     AIR QUALITY OBJECTIVE - The concentration and exposure time of one or more air contaminants in the ambient air below which, according to available knowledge, undesirable effects will not occur.

     AIR QUALITY STANDARD - An established concentration, exposure time and frequency of occurrence of one or more air contaminants in the ambient air which shall not be exceeded.

     ALLOWABLE EMISSIONS - The emission rate of a stationary source calculated using the maximum rated capacity of the stationary source (unless the stationary source is subject to federally enforceable limits which restrict the operating rate, or hours of operation, or both) and the most stringent of the following:

     a) The applicable standards as in 40 CFR Part 60, 61 or 63;

     b) Any applicable SIP emissions limitation including those with a future compliance date; or

     c) The emissions rate specified as a federally enforceable permit condition, including those with a future compliance date.

     b) The owner or operator notifies the NWCAA of the intent to relocate within the jurisdiction of the NWCAA at least fifteen (15) days prior to relocation;

     c) The owner or operator supplies sufficient information to enable the NWCAA to determine that the operation will comply with all applicable air pollution rules and regulations;

     d) The operation does not cause a violation of ambient air quality standards;

     e) If the operation is in a nonattainment area, it shall not interfere with the scheduled attainment of ambient standards;

     f) The temporary source operates in compliance with all applicable air pollution rules and regulations;

     g) A temporary source that is considered a major stationary source within the meaning of WAC 173-400-113 shall also comply with the requirements in WAC 173-400-720 through -750;

     h) Except for nonroad engines, all temporary sources shall have a valid Order of Approval to Construct from an air quality permitting organization in the State of Washington. The temporary source shall operate in compliance with the conditions set forth in the Order of Approval to Construct. Any reports required by the Order of Approval to Construct shall be submitted to the NWCAA;

     i) Permission to operate shall not exceed ninety (90) operating days in any calendar year anywhere within the jurisdiction of the NWCAA. The NWCAA may set specific conditions for operating during that time period. No source shall continue to operate beyond the allowable 90-day period unless an Order of Approval to Construct, or for nonroad engines, a regulatory order, has been issued by the NWCAA. For the purpose of this section, an operating day shall be considered any time equipment operates within a calendar day; and

     j) Except for nonroad engines, based on the source type and emission quantity, temporary sources may be subject to new source review at the discretion of the Control Officer.
