(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 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 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.

Current through Register Vol. 24-14, July 15, 2024
(1) New sources.
A notice of construction application for a new or modified
				toxic air pollutant source must quantify the increase in the emissions of each
				TAP, after application of tBACT, emitted by the new or modified emission
				units.
(2) Small quantity
			 emission rates.
A notice of construction application that relies on SQERs
				rather than dispersion modeling to demonstrate compliance with WAC
				173-460-070 must quantify the
				increase in emissions of each TAP emitted by the new or modified emission units
				after application of tBACT. The quantification must contain sufficient detail
				to demonstrate to the satisfaction of the permitting authority that the
				increase in emissions is less than the applicable small quantity emission rates
				listed in WAC
				173-460-150.
(3) Level of detail.
An acceptable source impact level analysis under WAC
				173-460-080 may be based on a
				conservative estimate of emissions that represents good engineering judgment.
				If compliance with WAC
				173-460-070 and
				173-460-080 cannot be
				demonstrated, more precise emission estimates may be used to demonstrate
				compliance with WAC
				173-460-090.

Current through Register Vol. 24-14, July 15, 2024
(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.

				173-460-080, may submit a
				petition requesting that ecology perform a second tier review to determine a
				means of compliance with WAC
				173-460-070. Petitions for second
				tier review must be submitted to ecology with a copy to the permitting
				authority with jurisdiction.
(2) Second tier petition submittal
			 requirements. Ecology will evaluate a second tier petition only if:
(a) The permitting authority submits to
			 ecology a preliminary order of approval that addresses all applicable new
			 source review issues with the exception of the outcome of the second tier
			 review, State Environmental Policy Act review, public notification, and
			 prevention of significant deterioration review; and
(b) The emission controls contained in the
			 preliminary order of approval represent at least tBACT; and
(c) The applicant has developed a health
			 impact assessment protocol that has been approved by ecology;
(d) The ambient impact of the emissions
			 increase of each TAP that exceeds acceptable source impact levels has been
			 quantified using refined air dispersion modeling techniques as approved in the
			 health impact assessment protocol; and
(e) The petition contains a health impact
			 assessment conducted in accordance with the approved health impact assessment
			 protocol.

Unless a different meaning is clearly required by context words
				and phrases used in this chapter shall have the following meanings: General
				terms common with other chapters as defined in chapter 173-400 WAC, and terms
				specific to the standards and limits of radionuclides as defined in this
				section.
(1) "ALARA" means as low as
			 reasonably achievable making every reasonable effort to maintain exposures to
			 radiation as far below the dose standards in this chapter as is practical,
			 consistent with the purpose for which the licensed activity is undertaken,
			 taking into account the state of technology, the economics of improvements in
			 relation to the state of technology, the economics of improvements in relation
			 to benefits to the public health and safety, and other socioeconomic
			 considerations, and in relation to the utilization of nuclear energy, ionizing
			 radiation, and radioactive materials in the public interest.
(2) "As low as reasonably achievable control
			 technology" (ALARACT) means the use of radionuclide emission control technology
			 that achieves emission levels that are consistent with the philosophy of
			 ALARA.
(3) Best available
			 radionuclide control technology "BARCT" means technology which will result in a
			 radionuclide emission limitation based on the maximum degree of reduction for
			 radionuclides which would be emitted from any proposed new or modified emission
			 units which the permitting authority on a case-by-case basis, taking into
			 account energy, environmental, and economic impacts and other costs, determines
			 is achievable for such emission unit or modification through application of
			 production processes or available methods, systems, and techniques. In no event
			 shall application of best available radionuclide technology result in emissions
			 of radionuclides which would exceed the ambient annual standard limitation
			 specified in this chapter.
(4)
			 "Effective dose equivalent" means the sum of the products of absorbed dose and
			 appropriate factors to account for differences in biological effectiveness due
			 to the quality of radiation and its distribution in the body of reference
			 man.
(5) "Radionuclide" means any
			 nuclide that emits radiation.
(6)
			 "Rem" means a unit of dose equivalent radiation.
