(1) "Actual emissions" means the actual rate of emissions of a pollutant from an emission unit, as determined in accordance wi th (a) through (c) of this subsection.

(a) In general, 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 part icular date and which is representative of normal source operation. Ecology or an authority shall allow the use of a different time period upon a determination that it is more representative of normal 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) Ecology or an authority may presume that 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.

(2) "Adverse impact on visibility" is defined in WAC 173

- 400

- 117.

(3) "Air contaminant" means dust, fumes, mist, smoke, other particulate matter, vapor, gas, odorous substance, or any combination thereof. "Air pollutant" means the same as "air

(1) All sources and emissions units are required to meet the emission standards of this chapter. Where an emission standard listed in another chapter is applicable to a specific emissions unit,
such standard takes precedence over a general emission standard l isted in this chapter. When two

TABLE 2

-- ADDITIONAL REGULATIONS APPROVED FOR WASHINGTON DEPARTMENT OF ECOLOGY (ECOLOGY) DIRECT JURISDICTION

– page 16or more emissions units are connected to a common stack and the operator elects not to provide the means or facilities to sample emissions from the individual emissions units, and the relative contributions of the individual emissions units to the common discharge are not readily distinguishable, then the emissions of the common stack must meet the most restrictive standard of any of the connected emissions units.

All emissions units are required to use reasonably available control technology (RACT) which may be determined for some sources or source categories to be more stringent than the applicable emission limitations of any chapter of Title 173 WAC. Where current c ontrols are determined to be less than RACT, the permitting authority shall, as provided in RCW 70.94.154

, define RACT for each source or source category and issue a rule or regulatory order requiring
the installation of RACT.

(2) Visible emissions. No person shall cause or allow the emission for more than three minutes, in any one hour, of an air contaminant from any emissions unit which at the emission point, or within a reasonable distance of the emission point, exceeds twenty percent opacity except:

(a) When the emissions occur due to soot blowing/grate cleaning and the operator can demonstrate that the emissions will not exceed twenty percent opacity for more than fifteen minutes in any eight consecutive hours. The intent of this provision is t o allow the soot blowing and grate cleaning necessary to the operation of boiler facilities. This practice, except for testing and trouble shooting, is to be scheduled for the same approximate times each day and the permitting authority must be advised of the schedule.

(b) When the owner or operator of a source supplies valid data to show that the presence of uncombined water is the only reason for the opacity to exceed twenty percent.

(c) When two or more emission units are connected to a common stack, the permitting authority may allow or require the use of an alternate time period if it is more representative of normal operations.

(d) When an alternate opacity limit has been established per RCW 70.94.331 (2)(c).

(e) Exemptions from twenty percent opacity standard.

(i) Visible emissions reader certification testing. Visible emissions from the "smoke generator" used for testing and certification of visible emissions readers per the requirements of
40 C.F. R. Part 60, Appendix A, Reference Method 9 and ecology methods 9A and 9B shall be exempt from compliance with the twenty percent opacity limitation while being used for certifying visible emission readers.

(A) No visible emissions shall cross the boundary of the military training site/reservation.

(B) The operation shall have in place methods, which have been reviewed and approved by the permitting authority, to detect changes in weather that would cause the obscurant to cross the site boundary either during the course of the exercise or prior to the start of the exercise. The approved methods shall include provisions that result in cancellation of the training exercise,
cease the use of obscurants during the exercise until weather conditions would allow such training to occur without causing obscurant to leave the site boundary of the military site/reservation.

(iii) Firefighter training. Visible emissions from fixed and mobile firefighter trai ning facilities while being used to train firefighters and while complying with the requirements of chapter 173

- 425 WAC.

(3) Fallout. No person shall cause or allow the emission of particulate matter from any source to be deposited beyond the property under direct control of the owner or operator of the source in sufficient quantity to interfere unreasonably with the use and enjoyment of the property upon which the material is deposited.

(4) Fugitive emissions. The owner or operator of any emissio ns unit engaging in materials handling, construction, demolition or other operation which is a source of fugitive emission:

(a) If located in an attainment area and not impacting any nonattainment area, shall take reasonable precautions to prevent the release of air contaminants from the operation.

(b) If the emissions unit has been identified as a significant contributor to the nonattainment status of a designated nonattainment area, the owner or operator shall be required to use
reasonable and a vailable control methods, which shall include any necessary changes in technology, process, or other control strategies to control emissions of the air contaminants for which nonattainment has been designated.

(5) Odors. Any person who shall cause or allow the generation of any odor from any source or activity which may unreasonably interfere with any other property owner's use and enjoyment of his property must use recognized good practice and procedures to reduce these odors to a reasonable minimum.

(6) Emissions detrimental to persons or property. No person shall cause or allow the emission of any air contaminant from any source if it is detrimental to the health, safety, or welfare of any person, or causes damage to property or business.

When the owner or operator of an emissions unit supplies emission data and can demonstrate to the permitting authority that there is no feasible method of reducing the concentration to less
than one th ousand ppm (on a dry basis, corrected to seven percent oxygen for combustion sources) and that the state and federal ambient air quality standards for sulfur dioxide will not be exceeded. In such cases, the permitting authority may require specific ambient air monitoring stations be established, operated, and maintained by the owner or operator at mutually approved locations. All sampling results will be made available upon request and a monthly summary will be submitted to the permitting authority.

(8) Concealment and masking. No person shall cause or allow the installation or use of any means which conceals or masks an emission of an air contaminant which would otherwise violate any provisions of this chapter.

(9) Fugitive dust.

(a) The o wner or operator of a source f or activity that generates fugitive dust must take reasonable precautions to prevent that fugitive dust from becoming airborne and must maintain and operate the source to minimize emissions.

(b) The owner or operator of a ny existing source or activity that generates fugitive dust that has been identified as a significant contributor to a PM

(1) Applicability. The owner or operator of any source may apply to the permitting authority for an emission reduction credit (ERC) if the source proposes to reduce its actual emissions rate for any contaminant regulated by state or federal law for which the emission requirement may be stated as an allowable limit in weight o f contaminant per unit time for the emissions units involved.

(2) Time of application. The application for an ERC must be made prior to or within one hundred eighty days after the emission reduction has been accomplished.

(3) Conditions. An ERC m ay be authorized provided the following conditions have been demonstrated to the satisfaction of the permitting authority.

(a) The quantity of emissions in the ERC shall be less than or equal to the old allowable emissions rate or the old actual emissions rate, whichever is the lesser, minus the new allowable emissions rate. The old actual emissions rate is the average em issions rate occurring during the most recent twenty

- four

- month period preceding the request for an ERC. An alternative twenty

four

- month period from within the previous five years may be accepted by the permitting authority if the owner or operator of the source demonstrates to the satisfaction of the permitting authority that the alternative period is more representative of actual operations of the unit or

source.
(b) The ERC application must include a description of all the changes that are required to accomplish the claimed emissions reduction, such as, new control equipment, process modifications, limitation of hours of operation, permanent shutdown of equipment, specified control practices, etc.

(c) The reduction must be: Greater than otherwi se required by an applicable emission standard, order of approval, or regulatory order and be permanent, quantifiable, and federally enforceable.

(d) The reduction must be large enough to be readily quantifiable relative to the source strength of the emissions unit(s) involved.

(e) No part of the emission reductions claimed for credit shall have been used as part of a determination of net emission increase, nor as part of an offsetting transaction under WAC 173

- 400

- 113(4) or 173

- 400

- 830, nor as pa rt of a bubble transaction under WAC 173

TABLE 2

-- ADDITIONAL REGULATIONS APPROVED FOR WASHINGTON DEPARTMENT OF ECOLOGY (ECOLOGY) DIRECT JURISDICTION

– page 63(f) No part of the emission reduction was included in the emission inventory used to demonstrate attainment or for reasonable further progress in an amendment to the state implementation plan.

(g) Concurrent with or prior to the authorization of an ERC, the applicant shall receive (have received) a federally enforceable regulatory order or permit that establishes total allowable
emissions from the source or emissions unit of the contaminant for whi ch the ERC is requested, expressed as weight of contaminant per unit time.

(h) The use of any ERC shall be consistent with all other federal, state, and local requirements of the program in which it is used.

(4) Additional information. Within thi rty days after the receipt of an ERC application and all supporting data and documentation, the permitting authority may require the submission of additional information needed to review the application.

(5) Approval. Within thirty days after all requ ired information has been received, the permitting authority shall approve or deny the application, based on a finding that conditions in subsection (3)(a) through (h) of this section have been satisfied or not. If the application is approved, the permitti ng authority shall:

(a) Issue a regulatory order or equivalent document to assure that the emissions from the source will not exceed the allowable emission rates claimed in the ERC application, expressed in weight of pollutant per unit time for each e mission unit involved. The regulatory order or equivalent document shall include any conditions required to assure that subsection (3)(a) through (h) of this section will be satisfied. If the ERC depends in whole or in part upon the shutdown of equipment, the regulatory order or equivalent document must prohibit operation of the affected equipment; and

(b) Issue a certificate of emission reduction credit. The certificate shall specify the issue date, the contaminants involved, the emission decrease exp ressed as weight of pollutant per unit time, the nonattainment area involved, if applicable, and the person to whom the certificate is issued.
The emission reduction credit listed in the certificate shall be less than the amount of emission
reduction achie ved by the source. The difference between the emission reduction and the emission reduction credit must be a decrease of at least one ton per year or one percent of the emission reduction, whichever decrease is greater.

(c) The certificate of emission reduction credit shall include the expiration date of the credit.

(d) For purposes of determining whether a stationary source is an existing stationary facility, the term "building, structure, facility, or installation" means all of the pollutant

- emitting activities which belong to the same industrial grouping, are located on one or more contiguous or adjacent properties, and are under the control of the same person (or persons under common control). Pollutant

- emitting activities shall be considered as part of the same major group (i.e., which have the same two digit code) as described in the Standard Industrial Classification Manual, 1972, as amended in the 1977 supplement.

(2) Ecology shall identify each existing stationary facility which may reasonably be anticipated to cause or contribute to visibility impair ment in any mandatory Class 1 federal area in Washington and any adjacent state.

(3) For each existing stationary facility identified under subsection (2) of this section, ecology, in consultation with the permitting authority shall determine BART for each air contaminant of concern and any additional air pollution control technologies that are to be required to reduce impairment from the existing stationary facility.

(4) Each existing stationary facility shall apply BART as new technology for con trol of the air contaminant becomes reasonably available if:

(a) The existing stationary facility emits the air contaminant contributing to visibility impairment;

(b) Controls representing BART for that air contaminant have not previously been re quired under this section; and

(c) The impairment of visibility in any mandatory Class 1 federal area is reasonably attributable to the emissions of the air contaminant.

(1) Applicability. These provisions shall apply to all sources except:

TABLE 2

-- ADDITIONAL REGULATIONS APPROVED FOR WASHINGTON DEPARTMENT OF ECOLOGY (ECOLOGY) DIRECT JURISDICTION

– page 73(a) Stacks for which construction had commenced on or before December 31, 1970, except where pollutants are being emitted from such stacks used by sources which were constructed, or reconstructed, or for which major modifications were carried out after December 31, 1970;

(b) Coal

- fired steam electric generating units subject to the provisions of Section 118 of the Federal Clean Air Act, which commenced operation before July 1, 1957, and for whose stacks
construction commenced before Februa ry 8, 1974;

(c) Flares;

(d) Outdoor burning for agricultural or silvicultural purposes as covered under the smoke management plan;

(e) Residential wood combustion and open burning for which episodic restrictions apply.

These provisions shall not be construed to limit the actual stack height.

(2) Prohibitions. No source may use dispersion techniques or excess stack height to meet ambient air quality standards or PSD increment limitations.

(a) Excess stack height. Excess stack he ight is that portion of a stack which exceeds the greater of:

(i) Sixty

- five meters, measured from the ground level elevation at the base of the stack; or

(ii) H g = H + 1.5L

where: H g = "good engineering practice" (GEP) stack height, measured from the ground level elevation at the base of the stack,

H = height of nearby structure(s) measured from the ground level elevation at the base of the stack,

L = lesser dimension, height or projected width, of nearb y structure(s), subject to the proviso below.

"Nearby," as used in this subsection for purposes of applying the GEP formula means that distance up to five times the lesser of the height or the width dimension of a structure, but not greater than 0.8 k ilometer (1/2 mile).

(b) Dispersion techniques. Increasing final exhaust gas plume rise by manipulating source process parameters, exhaust gas parameters, stack parameters, or combining exhaust gases from several existing stacks into one stack; or ot her selective handling of exhaust gas streams so as to increase the exhaust gas plume rise. This does not include:

TABLE 2

-- ADDITIONAL REGULATIONS APPROVED FOR WASHINGTON DEPARTMENT OF ECOLOGY (ECOLOGY) DIRECT JURISDICTION

– page 74(i) The reheating of a gas stream, following the use of a pollution control system, for the purpose of returning the gas to the temperat ure at which it was originally discharged from the facility generating the gas stream;

(ii) The merging of gas streams where:

(A) The source was originally designed and constructed with such merged gas streams, as demonstrated by the source owner (s) or operator(s).

(B) Such merging is part of a change in operation at the facility that includes the installation of pollution controls and is accompanied by a net reduction in the allowable emissions of a pollutant. This exclusion shall apply only to the emission limitation for the pollutant affected by such change in operation.

(C) Before July 8, 1985, such merging was part of a change in operation at the facility that included the installation of emissions control equipment or was carried out for sound economic or engineering reasons, and not primarily motivated by an intent to gain emissions credit for greater dispersion.

(3) Exception. EPA, ecology, or a permitting authority may require the use of a field study or fluid model to verify the creditable stack height for the source. This also applies to a source seeking credi t after the effective date of this rule for an increase in existing stack height up to that established by the GEP formula. A fluid model or field study shall be performed according to the procedures described in the EPA Guideline for Determination of Good Engineering Practice Height (Technical Support Document of the Stack Height Regulations). The creditable height demonstrated by a fluid model or field study shall ensure that the emissions from a stack do not result in excessive concentrations of any air pollutant as a result of atmospheric downwash, wakes, or eddy effects created by the source itself, nearby structures or nearby terrain features.

(a) "Nearby," as used in this subsection for conducting a field study or fluid model, means not greater t han 0.8 km, except that the portion of a terrain feature may be considered to be nearby which falls within a distance of up to ten times the maximum height of the feature, not to exceed two miles if such feature achieves a height 0.8 km from the stack that is at least forty percent of the GEP stack height or twenty

- six meters, whichever is greater, as measured from the ground

level elevation at the base of the stack. The height of the structure or terrain feature is measured from the ground

- level elevation at the base of the stack.

(b) "Excessive concentration" is defined for the purpose of determining creditable stack height under this subsection and means a maximum ground

- level concentration owing to a significant downwash effect which contributes to excursion over an ambient air quality standard. For sources subject to PSD review (WAC 173

- 400

- 720 and 40 C.F.R. 52.21) an excessive concentration alternatively means a maximum ground

- level concentration owing to a significant

TABLE 2

-- ADDITIONAL REGULATIONS APPROVED FOR WASHINGTON DEPARTMENT OF ECOLOGY (ECOLOGY) DIRECT JURISDICTION

– page 75downwash effect which contrib utes to excursion over a PSD increment. The emission rate used in this demonstration shall be the emission rate specified in the state implementation plan, or in the absence of such, the actual emission rate of the source. "Significant downwash effect" mea ns a maximum ground

- level concentration due to emissions from a stack due in whole or in part to downwash, wakes, and eddy effects produced by nearby structures or nearby terrain features which individually is at least forty percent in excess of the maximu m concentration experienced in the absence of such downwash, wakes, or eddy effects.

- 810 Major stationary source and major modification definitions.

The definitions in this section must be used in the major stationary source nonattainment area permitting requirements in WAC 173

- 400

- 800 through173

- 400

- 860 . If a term is defined differently in the federal program requirements for issuance, renewal and expiration of a Plant Wide Applicability Limit which are adopted by reference in WAC 173

- 400

- 850, then that definition is to be used for purposes of the Plant Wide Applicability Limi t program.

(1) Actual emissions means:

(a) The actual rate of emissions of a regulated NSR pollutant from an emissions unit, as determined in accordance with (b) through (d) of this subsection. This definition does not apply when calculating whet her a significant emissions increase has occurred, or for establishing a
PAL under WAC 173

- 400

- 850. Instead, "projected actual emissions" and "baseline actual emissions" as defined in subsections (2) and (23) of this section apply for those purposes.

(b) In general, actual emissions as of a particular date shall equal the average rate, in tons per year, at which the unit actually emitted the pollutant during a consecutive twenty

- four

- month period which precedes the particular date and which is represen tative of normal source operation. The permitting authority shall allow the use of a different time period upon a determination that it is more representative of normal source operation. Actual emissions shall be calculated using the unit's actual operatin g hours, production rates, and types of materials processed, stored, or combusted during the selected time period.

(c) The permitting authority may presume that source

- specific allowable emissions for the unit are equivalent to the actual emissions o f the unit.

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

(2) Baseline actual emissions means the rate of emissions, in tons pe r year, of a regulated NSR pollutant, as determined in accordance with (a) through (d) of this subsection.

(a) For any existing electric utility steam generating unit, baseline actual emissions means the average rate, in tons per year, at which the un it actually emitted the pollutant during any consecutive twenty

- four

- month period selected by the owner or operator within the five

- year period immediately preceding when the owner or operator begins actual construction of the project. The permitting autho rity shall allow the use of a different time period upon a determination that it is more representative of normal source operation.

(i) The average rate shall include emissions associated with startups, shutdowns, and malfunctions; and, for an emissio ns unit that is part of one of the source categories listed in subsection (14)(e) of this section, the definition of major stationary source, or for an emissions

TABLE 2

-- ADDITIONAL REGULATIONS APPROVED FOR WASHINGTON DEPARTMENT OF ECOLOGY (ECOLOGY) DIRECT JURISDICTION

– page 98unit that is located at a major stationary source that belongs to one of the listed source cat egories, the average rate shall include fugitive emissions (to the extent quantifiable).

(ii) The average rate shall be adjusted downward to exclude any noncompliant emissions that occurred while the source was operating above any emission limitation that was legally enforceable during the consecutive twenty

- four

- month period.

(iii) For a regulated NSR pollutant, when a project involves multiple emissions units, only one consecutive twenty

- four

- month period must be used to determine the baseline a ctual emissions for the emissions units being changed. A different consecutive twenty

- four

- month period can be used for each regulated NSR pollutant.

(iv) The average rate shall not be based on any consecutive twenty

- four

- month period for which there is inadequate information for determining annual emissions, in tons per year, and for adjusting this amount if required by (a)(ii) of this subsection.

(b) For an existing emissions unit (other than an electric utility steam generating unit),
baseline actual emissions means the average rate, in tons per year, at which the emissions unit actually emitted the pollutant during any consecutive twenty

- four

- month period selected by the owner or operator within the ten

- year period immediately preceding either the date the owner or operator begins actual construction of the project, or the date a complete permit application is received by the permitting authority for a permit required either under WAC 173

- 400

- 800 through173

- 400

- 860 or under a plan approved by th e administrator, whichever is earlier, except
that the ten

- year period shall not include any period earlier than November 15, 1990.

(i) The average rate shall include emissions associated with startups, shutdowns, and malfunctions; and, for an emissio ns unit that is part of one of the source categories listed in subsection (14)(e) of this section, the definition of major stationary source, or for an emissions unit that is located at a major stationary source that belongs to one of the listed source cat egories, the average rate shall include fugitive emissions (to the extent quantifiable).

(ii) The average rate shall be adjusted downward to exclude any noncompliant emissions that occurred while the source was operating above an emission limitation t hat was legally enforceable during the consecutive twenty

- four

- month period.

(iii) The average rate shall be adjusted downward to exclude any emissions that would have exceeded an emission limitation with which the major stationary source must current ly comply, had such major stationary source been required to comply with such limitations during the consecutive twenty

- four

- month period. However, if an emission limitation is part of a maximum achievable control technology standard that the administrator proposed or promulgated under 40 C.F.R. Part 63, the baseline actual emissions need only be adjusted if the state has taken credit for such emissions reductions in an attainment demonstration or maintenance plan as part of the
demonstration of attainment or as reasonable further progress to attain the NAAQS.

– page 99(iv) For a regulated NSR pollutant, when a project involves multiple emissions units, only one consecutive twenty

- four

- month period must be used to determine the baseline actual emissions
for the emissions units being changed. A different consecutive twenty

- four

- month period can be used for each regulated NSR pollutant.

(v) The average rate shall not be based on any consecutive twenty

- four

- month period for which there is inadequate information for determining annual emissions, in tons per year, and for adjusting this amount if required under (b)(ii) and (iii) of this subsection.

(c) For a new emissions unit, the baseline actual emissions for purposes of determining the
emissions increase t hat will result from the initial construction and operation of such unit shall equal zero; and thereafter, for all other purposes, shall equal the unit's potential to emit. In the latter case, fugitive emissions, to the extent quantifiable, shall be includ ed only if the emissions unit is part of one of the source categories listed in subsection (14)(e) of this section, the definition of major stationary source, or if the emissions unit is located at a major stationary source that belongs to one of the liste d source categories.

(d) For a PAL for a major stationary source, the baseline actual emissions shall be calculated for existing electric utility steam generating units in accordance with the procedures contained in (a) of this subsection, for other e xisting emissions units in accordance with the procedures contained in (b) of this subsection, and for a new emissions unit in accordance with the procedures contained in (c) of this subsection, except that fugitive emissions (to the extent quantifiable) s hall be included regardless of the source category.

(3) Building, structure, facility, or installation means all of the pollutant

- emitting activities which belong to the same industrial grouping, are located on one or more contiguous or adjacent

prope rties, and are under the control of the same person (or persons under common control) except the activities of any vessel. Pollutant

- emitting activities shall be considered as part of the same industrial grouping if they belong to the same major group (i.e ., which have the same two

digit code) as described in the Standard Industrial Classification Manual, 1972, as amended by the 1977 Supplement (U.S. Government Printing Office stock numbers 4101

- 0065 and 003

- 005

(7) Continuous emissions monitoring system ( CEMS) means all of the equipment that may be required to meet the data acquisition and availability requirements of this section, to sample, condition (if applicable), analyze, and provide a record of emissions on a continuous basis.

(8) Continuous pa rameter monitoring system (CPMS) means all of the equipment necessary to meet the data acquisition and availability requirements of this section, to monitor process and control device operational parameters (for example, control device secondary voltages a nd electric currents) and other information (for example, gas flow rate, O2 or CO2 concentrations), and to record average operational parameter value(s) on a continuous basis.

(9) Continuous emissions rate monitoring system (CERMS) means the total equ ipment required for the determination and recording of the pollutant mass emissions rate (in terms of mass per unit of time).

(10) Electric utility steam generating unit means any steam electric generating unit that is constructed for the purpose of s upplying more than one

- third of its potential electric output capacity and more than 25 MW electrical output to any utility power distribution system for sale. Any steam supplied to a steam distribution system for the purpose of providing steam to a steam

electric generator that would produce electrical energy for sale is also considered in determining the electrical energy output capacity of the affected facility.

(11) Emissions unit means any part of a stationary source that emits or would have the

p otential to emit any regulated NSR pollutant and includes an electric steam generating unit. For purposes of this section, there are two types of emissions units:

(a) A new emissions unit is any emissions unit which is (or will be) newly constructed a nd which has existed for less than two years from the date such emissions unit first operated.

(b) An existing emissions unit is any emissions unit that is not a new emissions unit. A replacement unit, as defined in subsection (25) of this section is an existing emissions unit.

Fugitive emissions are not included for those emissions units located at a facility whose primary activity is not represented by one of the source categories listed in subsection (14)(e) of this section, the definition of major stationary source and that are not, by themselves, part of a listed source category.

(b) For purposes of de termining the net emissions increase associated with a project, an increase or decrease in fugitive emissions is creditable only if it occurs at an emissions unit that is part of one of the source categories listed in subsection (14)(e) of this section, th e definition of major stationary source, or if the emission unit is located at a major stationary source that belongs to one of the listed source categories. Fugitive emission increases or decreases are not
creditable for those emissions units located at a facility whose primary activity is not represented by one of the source categories listed in subsection (14)(e) of this section, the definition of major stationary source, and that are not, by themselves, part of a listed source category.

(c) For pur poses of determining the projected actual emissions of an emissions unit after a project, fugitive emissions are included only if the emissions unit is part of one of the source categories listed in subsection (14)(e) of this section, the definition of maj or stationary source, or if the emission unit is located at a major stationary source that belongs to one of the listed source categories. Fugitive emissions are not included for those emissions units located at a facility whose primary activity is not rep resented by one of the source categories listed in subsection (14)(e) of this section, the definition of major stationary source, and that are not, by themselves, part of a listed source category.

(d) For purposes of determining the baseline actual em issions of an emissions unit, fugitive emissions are included only if the emissions unit is part of one of the source categories listed in subsection (14)(e) of this section, the definition of major stationary source, or if the emission unit

(b) The most stringent emissions limitation which is achieved in practice by such class or category of stationary sources. This limitation, when applied to a modification, means the lowest achievable emissions rate for the new or modified emissions units within a stationary source. In no event shall the application of the term permit a proposed new or modified stationary sourc e to emit any pollutant in excess of the amount allowable under an applicable new source standard of performance.

(14)(a) Major stationary source means any stationary source of air pollutants that emits, or has the potential to emit, one hundred tons per year or more of any regulated NSR pollutant, except that lower emissions thresholds apply in areas subject to sections 181

(iv) In lieu of using the method set out in (b)(i) through (iii) of this subsectio n, the owner or operator may elect to use the emissions unit's potential to emit, in tons per year. For this purpose, if the emissions unit is part of one of the source categories listed in subsection (14)(e) of this section, the definition of major statio nary source or if the emissions unit is located at a major stationary source that belongs to one of the listed source categories, the unit's potential to emit shall include fugitive emissions (to the extent quantifiable).

- by

- case basis, taking into account energy, environmental, and economic impacts and other costs, determines is achievable for such source or modification through application of production processes or available methods, systems, and techniques, includi ng fuel cleaning or treatment or innovative fuel combustion techniques for control of such pollutant. In no event shall application of best available control technology result in emissions of any pollutant which would exceed the emissions allowed by any ap plicable standard under 40 C.F.R. Part 60 or 61. If the reviewing authority determines that technological or economic limitations on the application of measurement methodology to a particular emissions unit would make the imposition of an emissions standar d infeasible, a design, equipment, work practice, operational standard, or combination thereof, may be prescribed instead to satisfy the requirement for the application of BACT. Such standard shall, to the degree possible, set forth the emissions reduction achievable by implementation of such design, equipment, work practice or operation, and shall provide for compliance by means which achieve equivalent results.

- 820 Determining if a new stationary source or modification to a stationary source is subject to these requirements.

(1) Any new major stationary source located anywhere in a nonattainment area designated under section 107 (d)(1)(A)(i) of the Federal Clean Air Act, that is major for the p ollutant for which the area is designated nonattainment is subject to the permitting requirements of WAC
173

- 400

- 830 through 173

- 400

- 850. Any major modification of an existing major stationary source that is major for the pollutant for which the area is de signated nonattainment and is located anywhere in a nonattainment area designated under section 107 (d)(1)(A)(i) of the Federal Clean Air Act, and that has a significant net emissions increase of the pollutant for which the area is designated nonattainment is subject to the permitting requirements of WAC 173

- 400

- 830 through173

- 400

- 850 . A modification to an existing major stationary source must use the

TABLE 2

-- ADDITIONAL REGULATIONS APPROVED FOR WASHINGTON DEPARTMENT OF ECOLOGY (ECOLOGY) DIRECT JURISDICTION

– page 114following procedures to determine if the modification would result in a significant net emissions
increase of the nonattainment pollutant.

(2) Except as otherwise provided in subsection (4) of this section, and consistent with the definition of major modification, a project is a major modification for a regulated NSR pollutant if it causes two types of em issions increases

- A significant emissions increase, and a significant net emissions increase. The project is not a major modification if it does not cause a significant emissions increase. If the project causes a significant emissions increase, then the project is a major modification only if it also results in a significant net emissions increase.

(3) The procedure for calculating (before beginning actual construction) whether a significant emissions increase (i.e., the first step of the process) wi ll occur depends upon the type of emissions units being modified, according to (a) through (c) of this subsection. For these calculations, fugitive emissions (to the extent quantifiable) are included only if the emissions unit is part of one of the source categories listed in the definition of major stationary source contained in WAC 173

- 400

- 810 (14)(e) or if the emissions unit is located at a major stationary source that belongs to one of the listed source categories. Fugitive emissions are not included fo r those emissions units located at a facility whose primary activity is not represented by one of the source categories listed in the definition of major stationary source contained in WAC 173

- 400

- 810 (14)(e) and that are not, by themselves, part of a list ed source category. The procedure for calculating (before beginning actual construction) whether a significant net emissions increase will occur at the major stationary source (i.e., the second step of the process) is contained in the
definition of net emi ssion increase. Regardless of any such preconstruction projections, a major modification results if the project causes a significant emissions increase and a significant net emissions increase.

(a) Actual

- to

- projected

- actual applicability test for pro jects that only involve existing emissions units. A significant emissions increase of a regulated NSR pollutant is projected to occur if the sum of the difference between the projected actual emissions and the baseline actual emissions, for each existing e missions unit, equals or exceeds the significant amount for that pollutant.

(b) Actual

- to

- potential test for projects that only involve construction of a new emissions unit(s). A significant emissions increase of a regulated NSR pollutant is projected to occur if the sum of the difference between the potential to emit from each new emissions unit following completion of the project and the baseline actual emissions of these units before the project equals or exceeds the significant amount for that poll utant.

(c) Hybrid test for projects that involve multiple types of emissions units. A significant emissions increase of a regulated NSR pollutant is projected to occur if the sum of the emissions increases for each emissions unit, using the method spe cified in (a) and (b) of this subsection as

TABLE 2

-- ADDITIONAL REGULATIONS APPROVED FOR WASHINGTON DEPARTMENT OF ECOLOGY (ECOLOGY) DIRECT JURISDICTION

– page 115applicable with respect to each emissions unit, for each type of emissions unit equals or exceeds the significant amount for that pollutant.

(4) Any major stationary source which has a PAL for a regulated NS R pollutant shall comply with requirements in WAC 173

- 400

- 850.

(5) The following specific provisions apply with respect to any regulated NSR pollutant emitted from projects at existing emissions units at a major stationary source (other than projects at a source with a PAL) in circumstances where there is a reasonable possibility that a project that is not a part of a major modification may result in a significant emissions increase of such pollutant, and the owner or operator elects to use the method specified in the definition of projected actual emissions contained in WAC 173

- 400

- 810 (23)(b)(i) through (iii) for calculating projected actual emissions.

(a) Before beginning actual construction of the project, the owner or operator shall document, and maintain a record of the following information:

(i) A description of the project;

(ii) Identification of the emissions unit(s) whose emissions of a regulated NSR pollutant could be affected by the project; and

(iii) A description of the applicability test used to determine that the project is not a major modification for any regulated NSR pollutant, including the baseline actual emissions, the projected actual emissions, the amount of emissions excluded under the definition of projected

a ctual emissions contained in WAC 173

- 400

- 810 (23)(b)(iii) and an explanation for why such amount was excluded, and any netting calculations, if applicable.

(b) Before beginning actual construction, the owner or operator shall provide a copy of the
inf ormation set out in (a) of this subsection to the permitting authority. This information may be submitted in conjunction with any NOC application required under the provisions of WAC 173

- 400

- 110. Nothing in this subsection shall be construed to require the owner or operator of such a unit to obtain any determination from the permitting authority before beginning actual
construction.

(c) The owner or operator shall monitor the emissions of any regulated NSR pollutant that could increase as a result of the project and that is emitted by any emissions units identified in (a)(ii) of this subsection; and calculate and maintain a recor d of the annual emissions, in tons per year on a calendar year basis, for a period of five years following resumption of regular operations after the change, or for a period of ten years following resumption of regular operations after the change if the pr oject increases the design capacity or potential to emit of that regulated NSR pollutant at such emissions unit.

-- ADDITIONAL REGULATIONS APPROVED FOR WASHINGTON DEPARTMENT OF ECOLOGY (ECOLOGY) DIRECT JURISDICTION

– page 116(d) The owner or operator shall submit a report to the permitting authority within sixty days after the end of each year during which reco rds must be generated under (c) of this subsection setting out the unit's annual emissions, as monitored pursuant to (c) of this subsection, during the year that preceded submission of the report.

(e) The owner or operator shall submit a report to the permitting authority if the annual emissions, in tons per year, from the project identified in (a) of this subsection, exceed the baseline actual emissions (as documented and maintained pursuant to (a)(iii) of this subsection), by a significant amount (as defined in the definition of significant) for that regulated NSR pollutant, and if such emissions differ from the preconstruction projection as documented and maintained pursuant to (a)(iii) of this subsection. Such report shall be submitted to the permit ting authority within sixty days after the end of such year. The report shall contain the following:

(i) The name, address and telephone number of the major stationary source;

(ii) The annual emissions as calculated pursuant to (d) of this subsec tion; and

(iii) Any other information that the owner or operator wishes to include in the report (e.g., an explanation as to why the emissions differ from the preconstruction projection).

(f) A "reasonable possibility" under this subsection occur s when the owner or operator calculates the project to result in either:

(i) A projected actual emissions increase of at least fifty percent of the amount that is a "significant emissions increase," (without reference to the amount that is a significa nt net emissions increase), for the regulated NSR pollutant; or

(ii) A projected actual emissions increase that, added to the amount of emissions excluded under the definition of projected actual emissions sums to at least fifty percent of the amount that is a "significant emissions increase," (without reference to the amount that is a significant net emissions increase), for the regulated NSR pollutant. For a project for which a reasonable possibility occurs only within the meaning of (f)(ii) of this subsection, and not also within the meaning of (f)(i) of this subsection, then (c) through (f) of this subsection does not apply to the project.

(6) For projects not required to submit the above information to the permitting authority as part of a not ice of construction application, the owner or operator of the source shall make the information required to be documented and maintained pursuant to subsection (5) of this section available for review upon a request for inspection by the permitting authori ty or the general public pursuant to the requirements contained in chapter 173

- 840 Emission offset requirements.

(1) The ratio of total actual emissions reductions to the emissions increase shall be 1.1:1 unless
an alterna tive ratio is provided for the applicable nonattainment area in subsection (2) through (4) of this section.

(2) In meeting the emissions offset requirements of WAC 173

- 400

- 830 for ozone nonattainment areas that are subject to sections 181

- 185B of the Federal Clean Air Act, the ratio
of total actual emissions reductions of VOC to the emissions increase of VOC shall be as follows:

(a) In any marginal nonattainment area for ozone

- 1.1:1;

(b) In any moderate nonattainment area for ozone

- 1.15:1 ;
(c) In any serious nonattainment area for ozone

- 1.2:1;

(d) In any severe nonattainment area for ozone

- 1.3:1; and

(e) In any extreme nonattainment area for ozone

- 1.5:1.

(3) Notwithstanding the requirements of subsection (2) of th is section for meeting the requirements of WAC 173

- 400

- 830, the ratio of total actual emissions reductions of VOC to the emissions increase of VOC shall be 1.15:1 for all areas within an ozone transport region that is subject to sections 181

- 185B of the Fe deral Clean Air Act, except for serious, severe, and extreme ozone nonattainment areas that are subject to sections 181

- 185B of the Federal Clean Air Act.

(4) In meeting the emissions offset requirements of this section for ozone nonattainment areas

t hat are subject to sections 171

- 179b of the Federal Clean Air Act (but are not subject to sections
181

- 185B of the Federal Clean Air Act, including eight

- hour ozone nonattainment areas subject to 40 C.F.R. 51.902(b)), the ratio of total actual emissions re ductions of VOC to the emissions increase of VOC shall be 1.1:1.

(5) Emission offsets used to meet the requirements of WAC 173

- 400

- 830 (1)(e), must be for the same regulated NSR pollutant.

(6) If the offsets are provided by another source, the re ductions in emissions from that source must be federally enforceable by the time the order of approval for the new or modified source is effective. An emission reduction credit issued under WAC 173

- 400

- 131 may be used to satisfy
some or all of the offset r equirements of this subsection.

TABLE 2

-- ADDITIONAL REGULATIONS APPROVED FOR WASHINGTON DEPARTMENT OF ECOLOGY (ECOLOGY) DIRECT JURISDICTION

– page 120(7) Emission offsets are required for the incremental increase in allowable emissions occurring during startup and shutdown operations at the new or modified emission units subject to nonattainment area major new source review. The incremental increase is the difference between the allowable emissions during normal operation and the allowable emissions for startup and shutdown contained in the nonattainment new source review approval.

(8) Emission offsets including those described in an emission reduction credit issued under
WAC 173

- 400

- 131, must meet the following criteria:

(a) The baseline for determining credit for emissions reductions is the emissions limit under the applicable state implementation plan in e ffect at the time the notice of construction application is determined to be complete, except that the offset baseline shall be the actual emissions of the source from which offset credit is obtained where:

(i) The demonstration of reasonable further progress and attainment of ambient air quality standards is based upon the actual emissions of sources located within the designated nonattainment area; or

(ii) The applicable state implementation plan does not contain an emissions limitation for that source or source category.

(b) Other limitations on emission offsets.

(i) Where the emissions limit under the applicable state implementation plan allows greater emissions than the potential to emit of the source, emissions offset credit will be allowed only for control below the potential to emit;

(ii) For an existing fuel combustion source, credit shall be based on the allowable emissions under the applicable state implementation plan for the type of fuel being burned at the time the
notic e of construction application is determined to be complete. If the existing source commits to switch to a cleaner fuel at some future date, an emissions offset credit based on the allowable (or actual) emissions reduction resulting from the fuels change is not acceptable, unless the permit or other enforceable order is conditioned to require the use of a specified alternative control measure which would achieve the same degree of emissions reduction should the source switch back to the higher emitting (dirt ier) fuel at some later date. The permitting authority must ensure that adequate long

- term supplies of the new fuel are available before granting emissions offset credit for fuel switches;

(iii) Emission reductions.

(A) Emissions reductions achie ved by shutting down an existing emission unit or curtailing production or operating hours may be generally credited for offsets if:

(I) Such reductions are surplus, permanent, quantifiable, and federally enforceable; and

TABLE 2

-- ADDITIONAL REGULATIONS APPROVED FOR WASHINGTON DEPARTMENT OF ECOLOGY (ECOLOGY) DIRECT JURISDICTION

– page 121(II) The shutdown or curtailment occurred after the last day of the base year for the SIP planning process. For purposes of this subsection, the permitting authority may choose to consider a prior shutdown or curtailment to have occurred after the las t day of the base year if the projected emissions inventory used to develop the attainment demonstration explicitly includes the preshutdown or precurtailment emissions from the previously shutdown or curtailed emission units. However, in no event may cred it be given for shutdowns that occurred before August 7, 1977.

(B) Emissions reductions achieved by shutting down an existing emissions unit or curtailing production or operating hours and that do not meet the requirements in subsection (8)(b)(iii)(A) of this section may be generally credited only if:

(I) The shutdown or curtailment occurred on or after the date the construction permit application is filed; or

(II) The applicant can establish that the proposed new emissions unit is a replacem ent for the shutdown or curtailed emissions unit, and the emissions reductions achieved by the shutdown or curtailment met the requirements of (7)(b)(iii)(A)(I) of this section.

(iv) All emission reductions claimed as offset credit shall be federally enforceable;

(v) Emission reductions used for offsets may only be from any location within the designated nonattainment area. Except the permitting authority may allow use of emission reductions from another area that is nonattainment for the same pol lutant, provided the following conditions are

met:

(A) The other area is designated as an equal or higher nonattainment status than the nonattainment area where the source proposing to use the reduction is located; and

(B) Emissions from the othe r nonattainment area contribute to violations of the standard in the nonattainment area where the source proposing to use the reduction is located.

(vi) Credit for an emissions reduction can be claimed to the extent that the reduction has not
been rel ied on in issuing any permit under 40 C.F.R. 52.21 or regulations approved pursuant to 40 C.F.R. Part 51 Subpart I or the state has not relied on it in demonstration of attainment or reasonable further progress.

(vii) The total tonnage of increased em issions, in tons per year, resulting from a major modification that must be offset in accordance with Section 173 of the Federal Clean Air Act shall be determined by summing the difference between the allowable emissions after the
modification and the actu al emissions before the modification for each emissions unit.

(9) No emissions credit may be allowed for replacing one hydrocarbon compound with another of lesser reactivity, except for those compounds listed in Table 1 of EPA's

TABLE 2
