EFSEC Adoption by Reference 

173-400-030 Definitions. 

Except as provided elsewhere in this chapter, the following definitions apply throughout the 

chapter: 

(1) "Actual emissions" means the actual rate of emissions of a pollutant from an emission unit, 

as determined in accordance with (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 particular 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" means visibility impairment which interferes with the 

management, protection, preservation, or enjoyment of the visitor's visual experience of the 

Federal Class I area. This determination must be made on a case-by-case basis taking into 

account the geographic extent, intensity, duration, frequency, and time of visibility impairment, 

and how these factors correlate with (a) times of visitor use of the Federal Class I area, and (b) 

the frequency and timing of natural conditions that reduce visibility. This term does not include 
TABLE 3 – ADDITIONAL REGULATIONS APPROVED FOR THE ENERGY FACILITIES SITE 

EVALUATION COUNCIL (EFSEC) JURISDICTION – page 3 

effects on integral vistas. 

(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 

contaminant." 

(4) "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. For the purposes of this chapter, 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. 

(5) "Allowable emissions" means 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 set forth in 40 CFR Part 60 or 61; 

(b) Any applicable state implementation plan 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. 

(6) "Ambient air" means the surrounding outside air. 

(7) "Ambient air quality standard" means an established concentration, exposure time, and 

frequency of occurrence of air contaminant(s) in the ambient air which shall not be exceeded. 

(8) "Authority" means any air pollution control agency whose jurisdictional boundaries are 

coextensive with the boundaries of one or more counties. 

(9) "Best available control technology (BACT)" means an emission limitation based on the 

maximum degree of reduction for each air pollutant subject to regulation under chapter 70.94 

RCW emitted from or which results from any new or modified stationary source, 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 source or modification 

through application of production processes and available methods, systems, and techniques, 

including fuel cleaning, clean fuels, or treatment or innovative fuel combustion techniques for 

control of each such pollutant. In no event shall application of the "best available control 

technology" result in emissions of any pollutants which will exceed the emissions allowed by 

any applicable standard under 40 CFR Part 60 and Part 61, as they exist on May 7, 1993, or their 

later enactments as adopted by reference by the director by rule. Emissions from any source 

utilizing clean fuels, or any other means, to comply with this paragraph shall not be allowed to 
TABLE 3 – ADDITIONAL REGULATIONS APPROVED FOR THE ENERGY FACILITIES SITE 

EVALUATION COUNCIL (EFSEC) JURISDICTION – page 4 

increase above levels that would have been required under the definition of BACT in the Federal 

Clean Air Act as it existed prior to enactment of the Clean Air Act Amendments of 1990. 

(10) "Best available retrofit technology (BART)" means an emission limitation based on the 

degree of reduction achievable through the application of the best system of continuous emission 

reduction for each pollutant which is emitted by an existing stationary facility. The emission 

limitation must be established, on a case-by-case basis, taking into consideration the technology 

available, the costs of compliance, the energy and nonair quality environmental impacts of 

compliance, any pollution control equipment in use or in existence at the source, the remaining 

useful life of the source, and the degree of improvement in visibility which may reasonably be 

anticipated to result from the use of such technology. 

(11) "Bubble" means a set of emission limits which allows an increase in emissions from a 

given emissions unit(s) in exchange for a decrease in emissions from another emissions unit(s), 

pursuant to RCW 70.94.155 and WAC 173-400-120. 

(12) "Capacity factor" means the ratio of the average load on equipment or a machine for the 

period of time considered, to the manufacturer's capacity rating of the machine or equipment. 

(13) "Class I area" means any area designated pursuant to §§ 162 or 164 of the Federal Clean 

Air Act as a Class I area. The following areas are the Class I areas in Washington state:

(26) "Existing stationary facility" means a stationary source of air pollutants which has the 

potential to emit two hundred fifty tons per year or more of any air pollutant. In determining 

potential to emit, fugitive emissions, to the extent quantifiable, must be counted. 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

amount of negligibly-reactive compounds in the source's emissions. 

State effective: 9/20/93; EPA effective: 6/2/95

173-400-040 General Standards for Maximum Emissions. 

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 will take precedent over a general emission standard listed in this chapter. When 

two or 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. Further, 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 controls are determined to be less than RACT, ecology or the 

authority shall, as provided in section 8, chapter 252, Laws of 1993, define RACT for each 

source or source category and issue a rule or regulatory order requiring the installation of RACT. 

(1) Visible emissions. No person shall cause or permit 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 to permit 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 ecology or 

the authority 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 sources are connected to a common stack, ecology or the 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). 

(2) Fallout. No person shall cause or permit the emission of particulate matter from any source 

to be deposited beyond the property under direct control of the owner(s) or operator(s) of the 

source in sufficient quantity to interfere unreasonably with the use and enjoyment of the property 

upon which the material is deposited. 
TABLE 3 – ADDITIONAL REGULATIONS APPROVED FOR THE ENERGY FACILITIES SITE 

EVALUATION COUNCIL (EFSEC) JURISDICTION – page 17 

(3) Fugitive emissions. The owner or operator of any emissions unit engaging in materials 

handling, construction, demolition or any 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, shall be required to use reasonable and available 

control methods, which shall include any necessary changes in technology, process, or other 

control strategies to control emissions of the contaminants for which nonattainment has been 

designated. 

(4) Odors. Any person who shall cause or allow the generation of any odor from any source 

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. 

(5) Emissions detrimental to persons or property. No person shall cause or permit 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. 

(6) Sulfur dioxide. 

No person shall cause or permit the emission of a gas containing sulfur dioxide from any 

emissions unit in excess of one thousand ppm of sulfur dioxide on a dry basis, corrected to seven 

percent oxygen for combustion sources, and based on the average of any period of sixty 

consecutive minutes, except: 

When the owner or operator of an emissions unit supplies emission data and can demonstrate to 

ecology or the authority that there is no feasible method of reducing the concentration to less 

than one thousand 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, ecology or the 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 ecology or the authority. 

(7) Concealment and masking. No person shall cause or permit 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. 

(8) Fugitive dust sources. 

(a) The owner or operator of a source of fugitive dust shall take reasonable precautions to 

prevent fugitive dust from becoming airborne and shall maintain and operate the source to 

minimize emissions. 
TABLE 3 – ADDITIONAL REGULATIONS APPROVED FOR THE ENERGY FACILITIES SITE 

EVALUATION COUNCIL (EFSEC) JURISDICTION – page 18 

(b) The owner(s) or operator(s) of any existing source(s) of fugitive dust that has been identified 

as a significant contributor to a PM-10 nonattainment area shall be required to use reasonably 

available control technology to control emissions. Significance will be determined by the criteria 

found in WAC 173-400-113(3). 

State effective: 9/20/93; EPA effective: 6/2/95

173-400-050 Emission Standards for Combustion and Incineration Units. 

(1) Combustion and incineration emissions units must meet all requirements of WAC 173-400-

040 and, in addition, no person shall cause or permit emissions of particulate matter in excess of 

0.23 gram per dry cubic meter at standard conditions (0.1 grain/dscf), except, for an emissions 

unit combusting wood derived fuels for the production of steam. No person shall allow or permit 

the emission of particulate matter in excess of 0.46 gram per dry cubic meter at standard 

conditions (0.2 grain/dscf), as measured by EPA method 5 or approved procedures contained in 

"Source Test Manual - Procedures For Compliance Testing," state of Washington, department of 

ecology, as of July 12, 1990, on file at ecology. 

(2) For any incinerator, no person shall cause or permit emissions in excess of one hundred ppm 

of total carbonyls as measured by applicable EPA methods or acceptable procedures contained in 

"Source Test Manual - Procedures for Compliance Testing," state of Washington, department of 

ecology, on file at ecology. Incinerators shall be operated only during daylight hours unless 

written permission to operate at other times is received from ecology or the authority. 

(3) Measured concentrations for combustion and incineration sources shall be adjusted for 

volumes corrected to seven percent oxygen, except when ecology or the authority determines 

that an alternate oxygen correction factor is more representative of normal operations. 

State effective: 3/22/91; EPA effective: 9/10/93

173-400-060 Emission Standards for General Process Units. 

General process units are required to meet all applicable provisions of WAC 173-400-040 and, 

no person shall cause or permit the emission of particulate material from any general process 

operation in excess of 0.23 grams per dry cubic meter at standard conditions (0.1 grain/dscf) of 

exhaust gas. EPA test methods from 40 CFR Appendix A which are adopted by reference and 

any other approved test procedures which are contained in ecology's "Source Test Manual - 

Procedures For Compliance Testing" as of July 12, 1990, will be used to determine compliance. 

State effective: 3/22/91; EPA effective: 9/10/93

173-400-081 Startup and Shutdown. 
TABLE 3 – ADDITIONAL REGULATIONS APPROVED FOR THE ENERGY FACILITIES SITE 

EVALUATION COUNCIL (EFSEC) JURISDICTION – page 19 

In promulgating technology-based emission standards and making control technology 

determinations (e.g., BACT, RACT, LAER, BART) ecology and the authorities shall consider 

any physical constraints on the ability of a source to comply with the applicable standard during 

startup or shutdown. Where ecology or the authority determines that the source or source 

category, operated and maintained in accordance with good air pollution control practice, is not 

capable of achieving continuous compliance with an emission standard during startup or 

shutdown, ecology or the authority shall include in the standard appropriate emission limitations, 

operating parameters, or other criteria to regulate the performance of the source during startup or 

shutdown conditions. In modeling the emissions of a source for purposes of demonstrating 

attainment or maintenance of national ambient air quality standards, ecology and the authorities 

shall take into account any incremental increase in allowable emissions under startup or 

shutdown conditions authorized by an emission limitation or other operating parameter adopted 

under this rule. Any emission limitation or other parameter adopted under this rule which 

increases allowable emissions during startup or shutdown conditions over levels authorized in an 

approved state implementation plan shall not take effect until approved by EPA as a SIP 

amendment. 

State effective: 9/20/93; EPA effective: 6/2/95

173-400-091 Voluntary Limits on Emissions. 

(1) Upon request by the owner or operator of a source, ecology or the authority with jurisdiction 

over the source shall issue a regulatory order that limits the source's potential to emit any air 

contaminant or contaminants to a level agreed to by the owner or operator and ecology or the 

authority with jurisdiction over the source. 

(2) A condition contained in an order issued under this section shall be less than the source's 

otherwise allowable annual emissions of a particular contaminant under all applicable 

requirements of the chapter 70.94 RCW and the FCAA, including any standard or other 

requirement provided for in the Washington state implementation plan. The term "condition" 

refers to limits on production or other limitations, in addition to emission limitations. 

(3) Any order issued under this section shall include monitoring, recordkeeping and reporting 

requirements sufficient to ensure that the source complies with any condition established under 

this section. Monitoring requirements shall use terms, test methods, units, averaging periods, 

and other statistical conventions consistent with the requirements of WAC 173-400-105. 

(4) Any order issued under this section shall be subject to the notice and comment procedures 

under WAC 173-400-171. 

(5) The terms and conditions of a regulatory order issued under this section shall be federally 

enforceable, upon approval of this section as an element of the Washington state implementation 

plan. Any proposed deviation from a condition contained in an order issued under this section 

shall require revision or revocation of the order.

EVALUATION COUNCIL (EFSEC) JURISDICTION – page 20 

State effective: 9/20/93; EPA effective: 6/2/95 

173-400-105 Records, Monitoring, and Reporting. 

The owner or operator of a source shall upon notification by the director of ecology, maintain 

records on the type and quantity of emissions from the source and other information deemed 

necessary to determine whether the source is in compliance with applicable emission limitations 

and control measures. 

(1) Emission inventory. The owner(s) or operator(s) of any air contaminant source shall submit 

an inventory of emissions from the source each year. The inventory may include stack and 

fugitive emissions of particulate matter, PM10, sulfur dioxide, carbon monoxide, total reduced 

sulfur compounds (TRS), fluorides, lead, VOCs, and other contaminants, and shall be submitted 

(when required) no later than one hundred five days after the end of the calendar year. The 

owner(s) or operator(s) shall maintain records of information necessary to substantiate any 

reported emissions, consistent with the averaging times for the applicable standards. 

(2) Monitoring. Ecology shall conduct a continuous surveillance program to monitor the quality 

of the ambient atmosphere as to concentrations and movements of air contaminants. 

As a part of this program, the director of ecology or an authorized representative may require any 

source under the jurisdiction of ecology to conduct stack and/or ambient air monitoring and to 

report the results to ecology. 

(3) Investigation of conditions. Upon presentation of appropriate credentials, for the purpose of 

investigating conditions specific to the control, recovery, or release of air contaminants into the 

atmosphere, personnel from ecology or an authority shall have the power to enter at reasonable 

times upon any private or public property, excepting nonmultiple unit private dwellings housing 

one or two families. 

(4) Source testing. To demonstrate compliance, ecology or the authority may conduct or require 

that a test be conducted of the source using approved EPA methods from 40 CFR 60 Appendix A 

which are adopted by reference, or approved procedures contained in "Source Test Manual - 

Procedures for Compliance Testing," state of Washington, department of ecology, as of July 12, 

1990, on file at ecology. The operator of a source may be required to provide the necessary 

platform and sampling ports for ecology personnel or others to perform a test of an emissions 

unit. Ecology shall be allowed to obtain a sample from any emissions unit. The operator of the 

source shall be given an opportunity to observe the sampling and to obtain a sample at the same 

time. 

(5) Continuous monitoring and recording. Owners and operators of the following categories of 

sources shall install, calibrate, maintain and operate equipment for continuously monitoring and 

recording those emissions specified. 

(a) Fossil fuel-fired steam generators. 
TABLE 3 – ADDITIONAL REGULATIONS APPROVED FOR THE ENERGY FACILITIES SITE 

EVALUATION COUNCIL (EFSEC) JURISDICTION – page 21 

(i) Opacity, except where: 

(A) Steam generator capacity is less than two hundred fifty million BTU per hour heat input; or 

(B) Only gaseous fuel is burned. 

(ii) Sulfur dioxide, except where steam generator capacity is less than two hundred fifty million 

BTU per hour heat input or if sulfur dioxide control equipment is not required. 

(iii) Percent oxygen or carbon dioxide where such measurements are necessary for the 

conversion of sulfur dioxide continuous emission monitoring data. 

(iv) General exception. These requirements do not apply to a fossil fuel-fired steam generator 

with an annual average capacity factor of less than thirty percent, as reported to the Federal 

Power Commission for calendar year 1974, or as otherwise demonstrated to ecology or the 

authority by the owner(s) or operator(s). 

(b) Sulfuric acid plants. 

Sulfur dioxide where production capacity is more than three hundred tons per day, expressed as 

one hundred percent acid, except for those facilities where conversion to sulfuric acid is utilized 

primarily as a means of preventing emissions to the atmosphere of sulfur dioxide or other sulfur 

compounds. 

(c) Fluid bed catalytic cracking units catalyst regenerators at petroleum refineries. 

Opacity where fresh feed capacity is more than twenty thousand barrels per day. 

(d) Wood residue fuel-fired steam generators. 

(i) Opacity, except where steam generator capacity is less than one hundred million BTU per 

hour heat input. 

(ii) Continuous monitoring equipment. The requirements of (e) of this subsection do not apply 

to wood residue fuel-fired steam generators, but continuous monitoring equipment required by 

(d) of this subsection shall be subject to approval by ecology. 

(e) Owners and operators of those sources required to install continuous monitoring equipment 

under this chapter shall demonstrate to ecology or the authority, compliance with the equipment 

and performance specifications and observe the reporting requirements contained in 40 CFR Part 

51, Appendix P, Sections 3, 4 and 5, promulgated October 6, 1975, and amended November 7, 

1986, which is adopted by reference. 

(f) Special considerations. If for reason of physical plant limitations or extreme economic 

situations, ecology determines that continuous monitoring is not a reasonable requirement, 

alternative monitoring and reporting procedures will be established on an individual basis. These 
TABLE 3 – ADDITIONAL REGULATIONS APPROVED FOR THE ENERGY FACILITIES SITE 

EVALUATION COUNCIL (EFSEC) JURISDICTION – page 22 

will generally take the form of stack tests conducted at a frequency sufficient to establish the 

emission levels over time and to monitor deviations in these levels. 

(g) Exemptions. This subsection (5) does not apply to any source which is: 

(i) Subject to a new source performance standard. These sources will be governed by WAC 

173-400-115. 

(ii) Not subject to an applicable emission standard. 

(h) Monitoring system malfunctions. A source may be temporarily exempted from the 

monitoring and reporting requirements of this chapter during periods of monitoring system 

malfunctions provided that the source owner(s) or operator(s) shows to the satisfaction of 

ecology or the authority that the malfunction was unavoidable and is being repaired as 

expeditiously as practicable. 

(6) Change in raw materials or fuels for sources not subject to requirements of the operating 

permit program. Any change or series of changes in raw material or fuel which will result in a 

cumulative increase in emissions of sulfur dioxide of forty tons per year or more over that stated 

in the initial inventory required by subsection (1) of this section shall require the submittal of 

sufficient information to ecology or the authority to determine the effect of the increase upon 

ambient concentrations of sulfur dioxide. Ecology or the authority may issue regulatory orders 

requiring controls to reduce the effect of such increases. Cumulative changes in raw material or 

fuel of less than 0.5 percent increase in average annual sulfur content over the initial inventory 

shall not require such notice. 

State effective: 9/20/93; EPA effective: 6/2/95

173-400-107 Excess Emissions. 

(1) The owner or operator of a source shall have the burden of proving to ecology or the 

authority or the decision-making authority in an enforcement action that excess emissions were 

unavoidable. This demonstration shall be a condition to obtaining relief under subsections (4), 

(5) and (6) of this section. 

(2) Excess emissions determined to be unavoidable under the procedures and criteria in this 

section shall be excused and not subject to penalty. 

(3) Excess emissions which represent a potential threat to human health or safety or which the 

owner or operator of the source believes to be unavoidable shall be reported to ecology or the 

authority as soon as possible. Other excess emissions shall be reported within thirty days after 

the end of the month during which the event occurred or as part of the routine emission 

monitoring reports. Upon request by ecology or the authority, the owner(s) or operator(s) of the 

source(s) shall submit a full written report including the known causes, the corrective actions 

taken, and the preventive measures to be taken to minimize or eliminate the chance of 
TABLE 3 – ADDITIONAL REGULATIONS APPROVED FOR THE ENERGY FACILITIES SITE 

EVALUATION COUNCIL (EFSEC) JURISDICTION – page 23 

recurrence. 

(4) Excess emissions due to startup or shutdown conditions shall be considered unavoidable 

provided the source reports as required under subsection (3) of this section and adequately 

demonstrates that the excess emissions could not have been prevented through careful planning 

and design and if a bypass of control equipment occurs, that such bypass is necessary to prevent 

loss of life, personal injury, or severe property damage. 

(5) Maintenance. Excess emissions due to scheduled maintenance shall be considered 

unavoidable if the source reports as required under subsection (3) of this section and adequately 

demonstrates that the excess emissions could not have been avoided through reasonable design, 

better scheduling for maintenance or through better operation and maintenance practices. 

(6) Excess emissions due to upsets shall be considered unavoidable provided the source reports 

as required under subsection (3) of this section and adequately demonstrates that: 

(a) The event was not caused by poor or inadequate design, operation, maintenance, or any other 

reasonably preventable condition; 

(b) The event was not of a recurring pattern indicative of inadequate design, operation, or 

maintenance; and 

(c) The operator took immediate and appropriate corrective action in a manner consistent with 

good air pollution control practice for minimizing emissions during the event, taking into 

account the total emissions impact of the corrective action, including slowing or shutting down 

the emission unit as necessary to minimize emissions, when the operator knew or should have 

known that an emission standard or permit condition was being exceeded. 

State effective: 9/20/93; EPA effective: 6/2/95

173-400-110 New Source Review (NSR). 

(1) Applicability 

(a) A notice of construction application must be filed by the owner or operator and an order of 

approval issued by ecology or an authority prior to the establishment of any new source or 

emission unit or modification which is listed in WAC 173-400-100 or required to obtain a permit 

under RCW 70.94.161. 

(b) Ecology or the authority may require that a notice of construction application be filed by the 

owner or operator of a proposed new source or modification and an order of approval issued by 

ecology or an authority prior to the establishment of any new source or emission unit or 

modification, other than a single family or a duplex dwelling. 

(c) New source review of a modification shall be limited to the emission unit or units proposed 
TABLE 3 – ADDITIONAL REGULATIONS APPROVED FOR THE ENERGY FACILITIES SITE 

EVALUATION COUNCIL (EFSEC) JURISDICTION – page 24 

to be added to an existing source or modified and the air contaminants whose emissions would 

increase as a result of the modification. 

(2) Completeness Determination Within thirty days of receipt of a notice of construction 

application, ecology or the authority shall either notify the applicant in writing that the 

application is complete or notify the applicant in writing of all additional information necessary, 

based upon review of information already supplied, to complete the application. For a project 

subject to PSD review under WAC 173-400-141 a completeness determination includes a 

determination that the application provides all information required to conduct PSD review. 

(3) Final Determination 

(a) Within sixty days of receipt of a complete application, ecology or the authority shall either 

issue a final decision on the application or, for those projects subject to public notice, initiate 

notice and comment procedures under WAC 173-400-171 on a proposed decision, followed as 

promptly as possible by a final decision. A person seeking approval to construct or modify a 

source that requires an operating permit may elect to integrate review of the operating permit 

application or amendment required under RCW 70.94.161 and the notice of construction 

application required by this section. A notice of construction designated for integrated review 

shall be processed in accordance with operating permit program procedures and deadlines. 

(b) Every final determination on a notice of construction application shall be reviewed and 

signed prior to issuance by a professional engineer or staff under the direct supervision of a 

professional engineer in the employ of ecology or the authority. 

(c) If the new source is a major stationary source or the change is a major modification, ecology 

or the authority shall submit any control technology determination included in a final order of 

approval to the RACT/BACT/LAER clearinghouse maintained by EPA. 

(4) Appeals An order of approval, any conditions contained in an order of approval, or the 

denial of a notice of construction application may be appealed to the pollution control hearings 

board as provided in chapter 43.21B RCW. Ecology or the authority shall promptly mail copies 

of each order approving or denying a notice of construction application to the applicant and to 

any other party who submitted timely comments on the application, along with a notice advising 

parties of their rights of appeal to the Pollution Control Hearings Board and, where applicable, to 

the EPA Environmental Appeals Board. 

(5) Portable Sources For portable sources which located temporarily at particular sites, the 

owner(s) or operator(s) shall be allowed to operate at the temporary location without filing a 

notice of construction application, providing that the owner(s) or operator(s) notifies ecology or 

the authority of intent to operate at the new location at least thirty days prior to starting the 

operation, and supplies sufficient information to enable ecology or the authority to determine that 

the operation will comply with the emission standards for a new source, and will not a cause a 

violation of applicable ambient air quality standards and , if in a nonattainment area, will not 

interfere with scheduled attainment of ambient standards. The permission to operate shall be for 

a limited period of time (one year or less) and ecology or the authority may set specific 
TABLE 3 – ADDITIONAL REGULATIONS APPROVED FOR THE ENERGY FACILITIES SITE 

EVALUATION COUNCIL (EFSEC) JURISDICTION – page 25 

conditions for operation during that period. A temporary source shall be required to comply with 

all applicable emission standards. 

(6) Approval to construct or modify a stationary source shall become invalid if construction is 

not commenced within eighteen months after receipt of such approval, if construction is 

discontinued for a period of eighteen months or more, or if construction is not completed within 

a reasonable time. Ecology or the authority may extend the eighteen-month period upon a 

satisfactory showing that an extension is justified. This provision does not apply to the time 

period between construction of the approved phases of a phased construction project; each phase 

must commence construction within eighteen months of the projected and approved 

commencement date.

WAC 173-400-112 Requirements for New Sources in Nonattainment Areas. 

Ecology or an authority reviewing an application to establish a new source or modification in a 

nonattainment area, shall issue an order of approval, which order shall contain such conditions as 

are reasonably necessary to assure the maintenance of compliance with this chapter, if they 

determine that the proposed project satisfies each of the following requirements: 

(1) The proposed new source or modification will comply with all applicable new source 

performance standards, national emission standards for hazardous air pollutants, emission 

standards adopted under chapter 70.94 RCW and, for sources regulated by an authority, the 

applicable emission standards of that authority. 

(2) The proposed new source will employ BACT for all air contaminants, except that if the new 

source is a major stationary source or the proposed modification is a major modification it will 

achieve LAER for the contaminants for which the area has been designated nonattainment and 

for which the proposed new source or modification is major. 

(3) The proposed new source will not cause any ambient air quality standard to be exceeded, will 

not violate the requirements for reasonable further progress established by the state 

implementation plan and will comply with WAC 173-400-113(3) for all contaminants for which 

the area has not been designated nonattainment. 

(4) If the proposed new source is a major stationary source or the proposed modification is a 

major modification, ecology or the authority has determined, based on review of an analysis 

performed by the source of alternative sites, sizes, production processes, and environmental 

control techniques, that the benefits of the project significantly outweigh the environmental and 

social costs imposed as a result of its location, construction, or modification. 

(5) If the proposed new source or the proposed modification is major for the contaminant for 

which the area is designated nonattainment, allowable emissions from the proposed new source 

or modification of that contaminant are offset by reductions in actual emissions from existing 
TABLE 3 – ADDITIONAL REGULATIONS APPROVED FOR THE ENERGY FACILITIES SITE 

EVALUATION COUNCIL (EFSEC) JURISDICTION – page 26 

sources in the nonattainment area. Emission offsets must be sufficient to ensure that total 

allowable emissions from existing major stationary sources in the nonattainment area, new or 

modified sources which are not major stationary sources, and the proposed new or modified 

source will be less than total actual emissions from existing sources (prior to submittal of the 

application) so as to represent (when considered together with the nonattainment provisions of 

section 172 of the FCAA) reasonable further progress. All offsetting emission reductions must 

satisfy the following requirements: 

(a) The proposed new level of allowable emissions of the source or emission unit(s) providing 

the reduction must be less than the current level of actual emissions of that source or emissions 

unit(s). No emission reduction can be credited for actual emissions which exceed the current 

allowable emissions of the source or emissions unit(s) providing the reduction. Emission 

reductions imposed by local, state, or federal regulations, regulatory orders, or permits cannot be 

credited. 

(b) The emission reductions must provide for a net air quality benefit. For marginal ozone 

nonattainment areas, the total emissions of volatile organic compounds or total emissions of 

nitrogen oxides are reduced by a ratio of 1.1 to 1 for the area in which the new source is located. 

For any other nonattainment area, the emissions offsets must provide a positive net air quality 

benefit in the nonattainment area. Determinations on whether emissions offsets provide a 

positive net air quality benefit will be made in accordance with the guidelines contained in 40 

CFR 51 Appendix S. 

(c) If the offsets are provided by another source, the reductions in emissions from that source 

must be federally enforceable by the time the new or modified source commences operation. 

The new source may not commence operation before the date such reductions are actually 

achieved. An emission reduction credit issued under WAC 173-400-131 may be used to satisfy 

some or all of the offset requirements of this subsection. 

(6) If the proposed new source is a major stationary source or the proposed modification is a 

major modification, the owner or operator has demonstrated that all major stationary sources 

owned or operated by such person (or by any entity controlling, controlled by, or under common 

control with such person) in Washington are subject to emission limitations and are in 

compliance, or on a schedule for compliance, with all applicable emission limitations and 

standards under the Federal Clean Air Act, including all rules contained in an EPA-approved 

state implementation plan. 

(7) If the proposed new source is a major stationary source or the proposed modification is a 

major modification for the purposes of the PSD program described in WAC 173-400-141, it 

meets the requirements of that program for all contaminants for which the area has not been 

designated nonattainment. 

(8) If the proposed new source or modification will emit any toxic air pollutants regulated under 

chapter 173-460 WAC, the source meets all applicable requirements of that chapter. 

(9) If the proposed new source is a major stationary source or the proposed modification is a 
TABLE 3 – ADDITIONAL REGULATIONS APPROVED FOR THE ENERGY FACILITIES SITE 

EVALUATION COUNCIL (EFSEC) JURISDICTION – page 27 

major modification, ecology or the authority has complied with the visibility protection review 

requirements of 40 CFR 52.28(c) through (e) except for (c)(4)(i), (g), and (h), as in effect on 

March 3, 1993, and determined that the project meets the criteria set forth in 40 CFR 52.28(g). 

For purposes of this subsection, definitions referenced in 40 CFR 52.28(b) are incorporated by 

reference, except that the term "visibility protection area" means any Class I area, and terms 

defined in WAC 173-400-030 shall have the meanings defined in that section. References in 40 

CFR 52.28 to "the Administrator" shall mean the agency (either ecology or the authority) 

processing the notice of construction application. 

State effective: 9/20/93; EPA effective: 6/2/95

173-400-113 Requirements for New Sources in Attainment or Unclassifiable Areas. 

Ecology or an authority reviewing an application to establish a new source or modification in an 

area that is in attainment or unclassifiable for any air contaminant the new source would emit and 

that is in attainment or unclassifiable for ozone if the proposed new or modified source would 

emit VOCs or NOX, shall issue an order of approval, which order shall contain such conditions as 

are reasonably necessary to assure the maintenance of compliance with this chapter, if they 

determine that the proposed project satisfies all of the following requirements: 

(1) The proposed new source or modification will comply with all applicable new source 

performance standards, national emission standards for hazardous air pollutants, emission 

standards adopted under chapter 70.94 RCW and, for sources regulated by an authority, the 

applicable emission standards of that authority. 

(2) The proposed new source or modification will employ BACT for all pollutants not 

previously emitted or whose emissions would increase as a result of the new source or 

modification. 

(3) Allowable emissions from the proposed new source or modification will not delay the 

attainment date for an area not in attainment nor cause or contribute to a violation of any ambient 

air quality standard. This requirement will be considered to be met if the projected impact of the 

allowable emissions from the proposed new source or the projected impact of the increase in 

allowable emissions from the proposed modification at any location within a nonattainment area 

does not exceed the following levels for the pollutant(s) for which the area has been designated 

nonattainment:

subsection. 

(4) If the proposed new source is a major stationary source or the proposed modification is a 

major modification for purposes of the PSD program described in WAC 173-400-141, it meets 

all applicable requirements of that chapter. 

(5) If the proposed new source or the proposed modification will emit any toxic air pollutants 

regulated under chapter 173-460 WAC, the source meets all applicable requirements of that 

program. 

(6) If, within the meaning of the PSD program described in WAC 173-400-141, the proposed 

new source is a major stationary source or the proposed modification is a major modification, 

ecology or the authority has complied with the visibility protection review requirements of 40 

CFR 52.27(d) through (f), as in effect on March 3, 1993, and has determined that the source 

would not cause an adverse impact upon visibility. References in 40 CFR 52.27 to "the 

Administrator" shall mean the agency (either ecology or the authority) processing the notice of 

construction application. 

State effective: 9/20/93; EPA effective: 6/2/95

173-400-151 Retrofit Requirements for Visibility Protection. 

(1) Determination of best available retrofit technology (BART). Ecology shall identify and 

analyze each source which may reasonably be anticipated to cause or contribute to impairment of 

visibility in any mandatory Class I area in Washington and any adjacent state and to determine 

BART for the contaminant of concern and those additional air pollution control technologies that 

are to be required to reduce impairment from the source. 

(2) Initially defined BART. The owner(s) or operator(s) of any source(s) to which significant 

visibility impairment of a mandatory Class I area is reasonably attributable shall apply BART for 

each contaminant contributing to visibility impairment that is emitted at more than 250 tons per 

year. Each source for which BART is required must install and operate BART as expeditiously 

as possible, but in no case later than five years after the conditions are included in a regulatory 

order. 

(3) Future definitions of BART. The owner(s) or operator(s) of any source(s) to which 

significant visibility impairment of a mandatory Class I area is reasonably attributable shall 

apply BART as new technology becomes available for a contaminant if: 

(a) The source emits more than 250 tons per year of the contaminant; and, 

(b) The controls representing BART have not previously been required in this section. 

(4) Appeal. Any source owner or operator required by this section to install, operate, and 

maintain BART, may apply to the EPA administrator for an exception from that requirement

pursuant to 40 CFR 51.303. 

State effective: 3/22/91; EPA effective: 6/2/95

173-400-161 Compliance Schedules. 

(1) Issuance. Whenever a source is found to be in violation of an emission standard or other 

provision of this chapter, ecology or the authority may issue a regulatory order requiring that the 

source be brought into compliance within a specified time. The order shall contain a schedule 

for installation, with intermediate benchmark dates and a final completion date, and shall 

constitute a compliance schedule. Requirements for public involvement (WAC 173-400-171) 

must be met. 

(2) Federal action. A source shall be considered to be in compliance with this chapter if all the 

provisions of its individual compliance schedule included with a regulatory order are being met. 

Such compliance does not preclude federal enforcement action by the EPA until and unless the 

schedule is submitted and adopted as an amendment to the state implementation plan. 

(3) Penalties for delayed compliance. Sources on a compliance schedule but not meeting 

emissions standards may be subject to penalties as provided in the Federal Clean Air Act. 

State effective: 3/22/91; EPA effective: 6/2/95

173-400-171 Public Involvement. 

(1) Applicability. 

Ecology or the authority shall provide public notice prior to the approval or denial of any of the 

following types of applications or other actions: 

(a) Notice of construction application for any new or modified source or emissions unit, if a 

significant net increase in emissions of any pollutant regulated by state or federal law would 

result; or 

(b) Any application or other proposed action for which a public hearing is required by PSD 

rules; or 

(c) Any order to determine RACT; or 

(d) An order to establish a compliance schedule or a variance; or

boundaries thereof; or 
TABLE 3 – ADDITIONAL REGULATIONS APPROVED FOR THE ENERGY FACILITIES SITE 

EVALUATION COUNCIL (EFSEC) JURISDICTION – page 30 

(f) An order to demonstrate the creditable height of a stack which exceeds the GEP formula 

height and sixty-five meters, by means of a fluid model or a field study, for the purposes of 

establishing an emission limitation; or 

(g) An order to authorize a bubble; or 

(h) Notice of construction application or regulatory order used to establish a creditable emission 

reduction; 

(i) An order issued under WAC 173-400-090 which establishes limitations on a source's 

potential to emit; or 

(j) Any application or other proposed action made pursuant to this chapter in which there is a 

substantial public interest according to the discretion of ecology or the authority. 

(2) Public notice. Public notice shall be made only after all information required by ecology or 

the authority has been submitted and after applicable preliminary determinations, if any, have 

been made. The cost of providing public notice shall be borne by the applicant or other initiator 

of the action. Public notice shall include: 

(a) Availability for public inspection in at least one location near the proposed project, of the 

nonproprietary information submitted by the applicant and of any applicable preliminary 

determinations, including analyses of the effect(s) on air quality. 

(b) Publication in a newspaper of general circulation in the area of the proposed project of 

notice: 

(i) Giving a brief description of the proposal; 

(ii) Advising of the location of the documents made available for public inspection; 

(iii) Advising of a thirty-day period for submitting written comment to ecology or the authority; 

(iv) Advising that a public hearing may be held if ecology or the authority determines within a 

thirty-day period that significant public interest exists. 

(c) A copy of the notice will be sent to the EPA regional administrator. 

Public participation procedures for notice of construction applications that are processed in 

coordination with an application to issue or modify an operating permit shall be conducted as 

provided in the state operating permit rule. 

(3) Public comment. No final decision on any application or action of any of the types 

described in subsection (1) of this section, shall be made until the public comment period has 

ended and any comments received have been considered. Unless a public hearing is held, the 

public comment period shall be the thirty-day period for written comment published as provided 
TABLE 3 – ADDITIONAL REGULATIONS APPROVED FOR THE ENERGY FACILITIES SITE 

EVALUATION COUNCIL (EFSEC) JURISDICTION – page 31 

above. If a public hearing is held the public comment period shall extend through the hearing 

date and thereafter for such period, if any, as the notice of public hearing may specify. 

(4) Public hearings. The applicant, any interested governmental entity, any group or any person 

may request a public hearing within the thirty-day period published as above. Any such request 

shall indicate the interest of the entity filing it and why a hearing is warranted. Ecology or the 

authority may, in its discretion, hold a public hearing if it determines significant public interest 

exists. Any such hearing shall be held upon such notice and at a time(s) and place(s) as ecology 

or the authority deems reasonable. 

(5) Other requirements of law. Whenever procedures permitted or mandated by law will 

accomplish the objectives of public notice and opportunity for comment, such procedures may be 

used in lieu of the provisions of this section. 

(6) Public information. Copies of notices of construction, orders, and modifications thereof 

which are issued hereunder shall be available for public inspection on request at ecology or the 

authority. 

State effective: 9/20/93; EPA effective: 6/2/95

173-400-190 Requirements for Nonattainment Areas. 

The development of specific requirements for nonattainment areas shall include consultation 

with local government in the area and shall include public involvement per WAC 173-400-171. 

State effective: 3/22/91; EPA effective: 6/2/95 

173-400-200 Creditable Stack Height and Dispersion Techniques. 

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

(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 February 8, 1974; 

(c) Flares; 

(d) Open burning for agricultural or silvicultural purposes as covered under the smoke 

management plan; 
TABLE 3 – ADDITIONAL REGULATIONS APPROVED FOR THE ENERGY FACILITIES SITE 

EVALUATION COUNCIL (EFSEC) JURISDICTION – page 32 

(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 height 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) Hg.= H.+ 1.5L 

where: Hg.= "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 nearby 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 kilometer (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 other selective handling of exhaust gas streams so as to 

increase the exhaust gas plume rise. This does not include: 

(i) The reheating of a gas stream, following the use of a pollution control system, for the purpose 

of returning the gas to the temperature 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. 
TABLE 3 – ADDITIONAL REGULATIONS APPROVED FOR THE ENERGY FACILITIES SITE 

EVALUATION COUNCIL (EFSEC) JURISDICTION – page 33 

(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 an 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 credit 

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 than 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 groundlevel 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 173-400-141 and 40 CFR 52.21) an excessive 

concentration alternatively means a maximum ground-level concentration owing to a significant 

downwash effect which contributes 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" means 

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 maximum concentration experienced 

in the absence of such downwash, wakes, or eddy effects. 

State effective: 3/22/91; EPA effective: 6/2/95

173-400-205 Adjustment for Atmospheric Conditions. 

Varying the rate of emission of a pollutant according to atmospheric conditions or ambient 

concentrations of that pollutant is prohibited, except as directed according to air pollution 

episode regulations.
