Original Board adoption 12/17/68 (Regulation 1 Sec 4.08); Amended by Board 10/29/69 (Regulation 2 Sec 3.03); Amended by Board 12/18/79 (400-100(3)); Amended by Board 12/18/79; Amended by Board 4/17/84; 93-21-004 filed 10/7/93, effective 11/8/93; 95-17-084 filed 8/21/95, effective 9/21/95; 99-07-028 filed 3/10/99, effective 4/11/99]

All air contaminant emissions units shall be registered with the ((~~Authority~~)) Agency except for the emissions units listed in this section. In the event that a registered source has any of these emissions units at a location that is otherwise required to be registered or obtain an operating permit, the ((~~Authority~~)) Agency may require that these emissions units be included on the permit or registration. However, registration fees shall not be assessed for any of the exempt emissions units. Any source exempted from registration under this section shall maintain sufficient documentation acceptable to the ((~~Authority~~)) Agency that the source is entitled to exemption under this section. Any source exempted from registration under this section shall also be considered exempt from the requirements of ((~~SWAPCA~~)) SWCAA 400-110, 400-111, 400-112, 400-113, and 400-114. For the purpose of identifying sources or emission units exempt from registration, the source's or emission unit's potential to emit shall be used as the basis for emissions and shall consider emissions before application of any control equipment. All exempt emission units shall be identified on an ~~Order of Authorization to Operate~~ inspection report for an otherwise registered source (refer to ((~~SWAPCA~~)) SWCAA 400-109). An exemption for an entire facility or source shall be valid only if the combined emissions from all emission units at that site or facility are less than 1.0 ton per year for criteria pollutants and VOCs and less than the Small Quantity Emission Rate for each toxic air pollutant identified in WAC 173-460. If any exemption threshold is exceeded for an emission unit or units, either individually or combined, the source or emission unit(s) shall not be considered to be exempt.

List of Exempt Emission Units or Sources as a Single Source or Emission Unit:

(1) Air conditioning or ventilating systems designed for space heating and cooling, combined or separate, that are less than 2.0 million Btu per hour which do not exhaust to the atmosphere contaminants generated by or released from process equipment.

(2) Any commercial or industrial manufacturing operation or business or process(es) associated with such operation or business which emits less than one ton per year combined of nitrogen oxides, carbon monoxide, PM₁₀, sulfur dioxide and volatile organic compounds from all emissions units combined. The one ton exemption does not apply to emissions of toxic air pollutants. Sources or emission units with emissions of toxic air pollutants to the ambient air may be exempted only if the annual emissions quantity for each toxic air pollutant is below the Small Quantity Emission Rate (annual rate) for each toxic air pollutant emitted as identified in WAC 173-460.

(3) Any commercial or industrial manufacturing operation or business or process(es) associated with such operation or business which is of insufficient stature to trigger a new source review fee assessment, from all emission units combined, as specified in Table A under ((~~SWAPCA~~)) SWCAA 400-110.

The inventory shall include stack and fugitive emissions of particulate matter, PM₁₀, sulfur dioxide, oxides of nitrogen, carbon monoxide, total reduced sulfur compounds (TRS), fluorides, lead, VOCs, and toxic air pollutants identified in WAC 173-460. 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. Emission reports shall be submitted to the Agency no later than March 15 of each year for the previous calendar year. Upon written request, an extension of the March 15 emission submittal deadline may be allowed by the Executive Director on a case-by-case basis.

(b) Larger sources. At a minimum, the sources satisfying the criteria of 40 CFR 51.320 et seq. (Subpart Q) will be submitted to EPA for inclusion in the national emission database. The emission inventory form supplied by the ((~~Authority~~)) Agency shall be completed and returned to the ((~~Authority~~)) Agency by ~~April~~ March 15th for the following sources. Upon written request, an extension of the March 15 emission submittal deadline may be allowed by the Executive Director on a case-by-case basis.

(i) Sources with the potential to emit over 100 tons of criteria pollutants, 10 tons of a single hazardous air pollutant or 25 tons of combined hazardous air pollutants, sources subject to NSPS, except Subpart AAA, and sources subject to NESHAPS, except Subpart M, sources are required to submit an emissions inventory. Only the hazardous air pollutants listed in Section 112 of the FCAA are considered for inclusion as hazardous air pollutant emissions for the purpose of determining those sources required to submit an emissions inventory.

(ii) In ozone nonattainment or maintenance plan areas, those sources that emit over 10.0 tons of VOCs per year or over 25.0 tons per year of NO_X are also required to submit emission inventories. Sources subject to this section are also required to submit average daily emissions or process throughput data for NO_X and VOCs for ozone season in preparation for the SIP update.

(iii) Sources with actual emissions or potential to emit greater than 50% of the Title V permit thresholds as identified in (i) above.

(iv) Synthetic minor or Title V opt out sources.

(2) Monitoring. The ((~~Authority~~)) Agency 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 Control Officer or an authorized representative may require any source under the jurisdiction of the ((~~Authority~~)) Agency to conduct stack and/or ambient air monitoring and to report the results to the ((~~Authority~~)) Agency.

(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 the ((~~Authority~~)) Agency shall have the power to enter at reasonable times upon any private or public property, excepting non-multiple unit private dwellings housing one or two families.

(e) Owners and operators of those sources required to install continuous monitoring equipment under this section shall demonstrate to the ((~~Authority~~)) Agency, 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, and 40 CFR 60 Appendices B through F, as appropriate, as in effect ((~~August~~)) July 1, ((~~1998~~)) 2000 which is adopted by reference.

(f) Special considerations. If for reason of physical plant limitations or extreme economic situations, the ((~~Authority~~)) Agency determines that continuous monitoring is not a reasonable requirement, alternative monitoring and reporting procedures shall be established on an individual basis. Alternative monitoring and reporting procedures may include continuous monitoring of process/operational parameters as a surrogate to continuous emissions monitoring and/or stack tests conducted at a frequency sufficient to determine compliance with applicable regulations and permit requirements as well as to quantify emissions.

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

(i) Subject to a new source performance standard. NSPS sources shall be governed by ((~~SWAPCA~~)) SWCAA 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 section during periods of monitoring system malfunctions provided that the source owner(s) or operator(s) shows to the satisfaction of the ((~~Authority~~)) Agency that the malfunction was unavoidable and is being repaired as expeditiously as practicable.

(5) 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 ((~~SWAPCA~~)) SWCAA 400-105(1) shall require the submittal of sufficient information to the ((~~Authority~~)) Agency to determine the effect of the increase upon ambient concentrations of sulfur dioxide. The ((~~Authority~~)) Agency 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 or decrease in average annual sulfur content over the initial inventory shall not require such notice.

(6) Misrepresentation. No person shall make any false material statement, representation or certification in any form, notice, or report required under Chapter 70.94 or 70.120 RCW, or any ordinance, resolution, regulation, permit or order in force pursuant thereto.

(7) Tampering. No person shall render inaccurate any monitoring device or method required under Chapter 70.94 or 70.120 RCW, or any ordinance, resolution, regulation, permit, or order in force pursuant thereto.

Original Board adoption 12/17/68 (Regulation 1 Sec 3); Amended by Board 12/18/79; Amended by Board 8/18/81; Amended by Board 3/20/84; 92-06-015 filed 2/25/92, effective 3/25/92; 93-21-004 filed 10/7/93, effective 11/8/93; 95-17-084 filed 8/21/95, effective 9/21/95; 99-07-030 filed 3/10/99, effective 4/11/99]

(1) Applicability.

(a) New Source Review (NSR) means that if the new source, modification or substantial alteration or replacement, meets the definition of "new source" then that new source or modification must demonstrate that all applicable emission standards have been or will be met by the proposed modification or new source. A complete Notice of Construction application shall be submitted for each source required to submit an application under the requirements of this section. Confidential information shall be identified as set forth in ((~~SWAPCA~~)) SWCAA 400-270.

Before the ((~~Authority~~)) Agency may review a Notice of Construction application, a filing fee of $300.00 and a review fee, as shown in Table A shall be submitted by the applicant. If offsetting emission reductions or other types of review identified in Table B are required to be performed by the ((~~Authority~~)) Agency as a result of the proposed installation, alteration, or modification, an additional review fee shall be paid. (Total Fee = Filing Fee + Review Fee [Table A] + Additional Review Fee [Table B]).

Notice of Construction application review fees based on emissions are to utilize actual or approved emissions, after controls, as supported by test data or emission factors, not potential to emit. Other review fees as noted in the fee tables are based on design capacities of the source equipment. Where a source may fall under multiple categories, only one fee per application shall apply; Table A fees are not considered additive as they apply to an application. In general, the fee determination shall be based on the primary emission unit or activity of the new, modified or altered source.

The significant impact criteria are used to determine if a proposed project or modification will cause a significant deterioration in ambient air quality for Class II areas. If a proposed project impacts (i.e., changes in ambient concentrations resulting from the proposed project or modification alone) are predicted to be less than the significant impact criteria, then the air quality analysis is complete at that point. If the ambient impact of a proposed project or modification exceeds these levels, compliance with available PSD increments and AAQS must then be demonstrated. If a proposed project or modification exceeds the significant ambient concentrations for Class II areas, monitoring of existing ambient air quality may be required if data sufficient to characterize background air quality are not available.

(2) Completeness determination. Within thirty (30) calendar days of receipt of a Notice of Construction application, the ((~~Authority~~)) Agency 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 as provided under RCW 70.94.152. For a project subject to PSD review under ((~~SWAPCA~~)) SWCAA 400-141 a completeness determination includes a determination that the application provides all information required to conduct PSD review. The ((~~Authority~~)) Agency may request additional clarification of information submitted from the source after a completeness determination has been made for a Notice of Construction application.

(3) Final determination/Regulatory Orders.

(a) Within sixty (60) calendar days of receipt of a complete application, the ((~~Authority~~)) Agency shall either issue a final decision on the application or, for those projects subject to public notice, issue a preliminary determination and initiate notice and comment procedures under ((~~SWAPCA~~)) SWCAA 400-171 on a proposed decision, followed as promptly as possible by a final decision. An owner or operator seeking 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 application designated for integrated review shall be processed in accordance with WAC 173-401 procedures and deadlines.

(b) Every final determination on a Notice of Construction application that results in the issuance of an Order of Approval by the ((~~Authority~~)) Agency 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 the ((~~Authority~~)) Agency.

(c) If the new source is a major stationary source or the change is a major modification, the ((~~Authority~~)) Agency shall submit any control technology determination(s) 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, the denial of a Notice of Construction application, or any other regulatory order issued by the ((~~Authority~~)) Agency, may be appealed to the Board of Directors as specified in ((~~SWAPCA~~)) SWCAA 400-220 of this regulation or appealed directly to the Pollution Control Hearings Board within 30 calendar days of receipt as provided in Chapter 43.21B RCW. The ((~~Authority~~)) Agency 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 the 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 locate 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 for each location provided that:

(a) The source/emissions units are registered with the ((~~Authority~~)) Agency.

(b) The source/emissions units have an Order of Approval as a portable source.

(c) The owner(s) or operator(s) notifies the ((~~Authority~~)) Agency of intent to operate at the new location at least ten business days prior to starting the operation.

(d) The owner(s) or operator(s) supplies sufficient information including production quantities and hours of operation, to enable the ((~~Authority~~)) Agency to determine that the operation will comply with the emission standards for a new source, and will not cause a violation of applicable ambient air quality standards and, if in a nonattainment area, will not interfere with scheduled attainment of ambient standards.

(e) The owner(s) and/or resident(s) of immediately adjacent properties shall be notified by the owner(s) or operator(s) of the portable source in writing at least 10 business days prior to commencement of operations at the proposed location with copies mailed to the ((~~Authority~~)) Agency. Written notification to the adjacent landowners/residents shall be by certified mail with return receipt requested. Such written notification shall include a complete description of the proposed operation, the associated emissions control provisions and equipment, the total estimated project emissions, the name, address and phone number of the person in charge of the operation, and the address and phone number for ((~~SWAPCA~~)) SWCAA. Written notification shall indicate that all comments shall be directed to the ((~~Authority~~)) Agency.

Sources that do not operate within the jurisdiction of the Agency for a period of more than 5 years shall be considered to be nonoperational and will be removed from active registration. Any such source shall be required to go through new source review prior to operating again within the jurisdiction of the Agency consistent with the definition of new source.

(6) Compliance. Noncompliance with any emission limit, test requirement, reporting requirement or other requirement identified in a regulatory order issued pursuant to this section shall be considered a violation of this section.

(7) Expiration. Approval to construct or modify a stationary source shall become invalid if construction is not commenced within eighteen months after the date of issuance of an Order of Approval, if construction is discontinued for a period of eighteen months or more, or if construction is not completed within a reasonable time. The ((~~Authority~~)) Agency may extend the eighteen-month period upon a satisfactory demonstration 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. The ((~~Authority~~)) Agency may specify an earlier date for commencement of construction in an Order of Approval.

(8) Temporary, Emergency, or Substitution Sources.

(a) A temporary source shall be considered to be a new source. The ((~~Authority~~)) Agency may require that a Notice of Construction application and applicable review fees be submitted before reviewing a request for a temporary, emergency or substitution source. The ((~~Authority~~)) Agency may provide approval for special situations for a source without meeting the requirements for New Source Review when one or more of the following conditions are met:

(i) The temporary source is needed to replace a previously approved similar source where the approved source is non-functional due to breakdown or other similar circumstances beyond the control of the owner or operator. This may include replacement steam or power supply units where facilities have an immediate need to continue production or service to public or private industries, or have a need for an extended or unscheduled shutdown of equipment that is of a duration not otherwise planned for. The ((~~Authority~~)) Agency may provide written approval for a temporary source that may include but not be limited to emission limits, operational or maintenance requirements or limitations, monitoring and reporting requirements, and testing requirements. Installation of a temporary source due to poor or improper maintenance or operations is required to submit a Notice of Construction application for permanent replacement within 30 days of installation.

(ii) The temporary source is necessary to support public or private needs in the event of a local or regional disaster when proper planning could not be accommodated. In no event shall the temporary source be authorized for operations for durations greater than three months. Written approval shall be provided by the ((~~Authority~~)) Agency that may contain, but not be limited to: emission limits, operation and maintenance requirements and limitations, monitoring and reporting requirements, and testing requirements. For operations greater than three months the owner or operator shall submit a Notice of Construction application under New Source Review requirements (((~~SWAPCA~~)) SWCAA 400-110) for approval from the ((~~Authority~~)) Agency.

(iii) The temporary source is a one time special need, urgent application, that can not otherwise be accommodated through the New Source Review process due to the critical nature of the source and time constraints. As a condition of approval under this expedited approval process, a new source of this type could not request to be allowed or expected to operate within the jurisdiction of the ((~~Authority~~)) Agency for the following three years. Written approval shall be provided by the ((~~Authority~~)) Agency that may contain but not be limited to: emission limits, operation and maintenance requirements and limitations, monitoring and reporting requirements and testing requirements. In no case shall approval be provided for operation greater than three months. For operations greater than three months, the owner or operator shall submit a Notice of Construction application under the New Source Review requirements of ((~~SWAPCA~~)) SWCAA 400-110.

(b) An emergency source is the result of an emergency situation that could not otherwise be planned for. The ((~~Authority~~)) Agency shall provide written approval for an emergency source provided that the owner or operator has provided sufficient documentation or demonstration of the need for the source to the satisfaction of the Control Officer. The written approval may include but not be limited to: emission limits, operation and maintenance requirements and limitations, monitoring and reporting requirements, and testing requirements. In no case shall approval be provided for operations greater than three months.

(c) A substitute source is the same as a temporary source as in (a) above. A substitute source may be of a different manufacturer and model number and size and may result in increased emissions from installation from previously approved equipment on a short-term basis. The ((~~Authority~~)) Agency shall provide written approval for a substitute source that may include but not be limited to: emission limits, operational or maintenance requirements or limitations, monitoring and reporting requirements, and testing requirements. In no event shall the substitute source be authorized for operations for durations greater than three months. For operations greater than three months, the owner or operator shall submit a Notice of Construction application under the New Source Review requirements of ((~~SWAPCA~~)) SWCAA 400-110.

AMENDATORY SECTION (Amending WSR 99-07-028, filed 3/10/99, effective 4/11/99)

((~~SWAPCA~~)) SWCAA 400-111 Requirements for Sources in a Maintenance Plan Area

[Statutory Authority: Chapter 70.94.141 RCW. Original Board adoption 95-17-084 filed 8/21/95, effective 9/21/95; 99-07-028 filed 3/10/99, effective 4/11/99]

Any person proposing to install, construct or operate a new source or emission unit or make a modification to an existing source or emission unit shall file a Notice of Construction application with the ((~~Authority~~)) Agency in accordance with ((~~SWAPCA~~)) SWCAA 400-109 and shall be subject to the New Source Review provisions of ((~~SWAPCA~~)) SWCAA 400-110. Confidential information shall be identified as set forth in ((~~SWAPCA~~)) SWCAA 400-270. A Notice of Construction application to establish a new source or make a modification to a source in an area that is covered by a maintenance plan, shall result in the issuance of an Order of Approval or other regulatory order. Such order shall contain such conditions as are reasonably necessary to assure the maintenance of compliance with this section, if it is determined that the proposed project satisfies all of the requirements of this section. New sources or modifications within a designated maintenance plan area, including sources of VOC or NO_x in a designated ozone maintenance plan area, shall meet the requirements listed below.

(1) Emission Standards. The proposed new source or modification shall:

(a) comply with all applicable New Source Performance Standards, National Emission Standards for Hazardous Air Pollutants, emission standards adopted under Chapter 70.94 RCW and, the applicable emission standards of the ((~~Authority~~)) Agency; and

(b) not cause any ambient air quality standard as provided in ((~~SWAPCA~~)) SWCAA 400-113(3) to be exceeded; and

(c) not violate the requirements for reasonable further progress established by the Washington State Implementation Plan; and

(d) minimize emissions to the extent that the new source or modification will not delay the attainment date for a nonattainment area, exceed emission levels or other requirements provided in a maintenance plan for an area that was previously identified as a nonattainment area, nor cause or contribute to a violation of any ambient air quality standard.

(2) BACT. Except as provided in Section (7) of this section, the owner or operator of the proposed new source or modification shall apply BACT for each pollutant. In the case of a modification, the requirement for BACT shall apply to each new or modified emission unit which increases emissions. For phased construction projects, the determination of BACT shall be reviewed at the latest reasonable time prior to commencement of construction of each independent phase.

(3) Source Compliance. The owner or operator of the proposed new source or modification shall certify that all sources owned or operated by such person (or by an entity controlling, controlled by, or under common control with such person) in Washington are in compliance or on a schedule for compliance, with all applicable emission limitations and standards under the Washington Clean Air Act (RCW 70.94).

(4) Offsets or Growth Allowance. The owner or operator of a proposed new major source or major modification shall provide offsets as specified in Section (8) of this section. Except as provided in Section (7) of this section, the requirements of this Section may be met in whole or in part in an ozone maintenance plan area with an allocation by ((~~SWAPCA~~)) SWCAA from a growth allowance, if available, in accordance with Section (8) of this section and the applicable maintenance plan in the SIP adopted by the Board and approved by EPA.

(5) Net Air Quality Benefit. For cases in which emission reduction or offsets are required in accordance with Section (4) above, the applicant shall demonstrate that a net air quality benefit will be achieved in the maintenance plan area. If the proposed new source or the proposed modification is major for the contaminant for which the area has a maintenance plan, allowable emissions of the maintenance pollutant from the proposed new source or modification shall be offset by reductions in actual emissions of the maintenance pollutant. All offsetting emission reductions must satisfy the following requirements of Section (8).

(6) Alternative Analysis.

(a) Except as provided in Subsection (c) of this section, the owner or operator of a proposed major source or major modification shall conduct an alternatives analysis;

(b) This analysis shall include an evaluation of alternative sites, sizes, production processes, and environmental control techniques for such proposed source or modification ((~~which~~)) that demonstrates that benefits of the proposed source or modification significantly outweigh the environmental and social costs imposed as a result of its location, construction or modification;

(c) This analysis shall not be required for a major source or major modification that is subject to this rule due to emissions of particulate matter in a designated TSP maintenance area.

(7) Contingency Plan Requirements. If the contingency plan in an applicable maintenance plan (CO or ozone) has been triggered due to a violation of an ozone ambient air quality standard or a second violation of the CO ambient air quality standard, this Section shall apply in addition to other requirements of this rule and the applicable approved maintenance plan adopted by the Board and approved by EPA as a revision to the SIP.

(a) The requirements for BACT in Section (2) of this Section shall be replaced by a requirement for LAER. If the new source is a major stationary source or the proposed modification is a major modification, it must achieve LAER for the maintenance pollutant and for which the proposed new source or modification is major.

(b) An allocation from a growth allowance shall not be used to meet the requirement for offsets in Section (4) of this Section. The growth allowance emissions shall be unavailable until such time as sufficient demonstration is made to reinstate the growth allowance emissions.

(8) Industrial Growth Allowance and Offset Allocation.

(a) Industrial growth allowances for sources in a maintenance plan area are identified in and governed by the Washington State Implementation Plan and the applicable maintenance plan for the applicable maintenance plan area.

(b) The growth allowance emissions may be increased or decreased as provided in a revision to the maintenance plan submitted to and approved by EPA. In the event of a confirmed ozone violation, the growth allowance for VOC and NO_x emissions shall be eliminated and new sources shall be required to implement LAER and offsets. Growth allowance emissions may be reinstated as provided in the EPA approved maintenance plan.

(c) The owner or operator of a proposed new major source or major modification emitting VOCs or NO_x, may obtain a portion of any remaining emissions in the respective growth allowance in accordance with the following process:

(i) Access is on a first-come-first-served basis, based on the date of a complete notice of construction and allowance allocation request;

(ii) No single source may receive an emissions allocation of more than 50% of any remaining growth allowance, or up to 10.0 tons per year, which ever is greater. On a case-by-case basis, the ((~~SWAPCA~~)) SWCAA Board of Directors may approve an emissions allocation of greater than 50% upon consideration of the following:

(A) Information submitted by the source to ((~~SWAPCA~~)) SWCAA justifying it's request for exceeding the 50% emissions allocation, based on significant economic, employment, or other benefits to the maintenance plan area that will result from the proposed new major source or major modification;

(B) Information provided by ((~~SWAPCA~~)) SWCAA on other known new major sources or major modifications seeking an emissions allocation from the same growth allowance; and

(iii) To avoid jeopardizing maintenance of the ozone standard during the interim years of the ozone maintenance plan, ((~~SWAPCA~~)) SWCAA shall allocate only a portion of the VOC and NO_x growth allowances each year. ((~~SWAPCA~~)) SWCAA will track use of VOC and NO_x emissions from the growth allowances. The amount of the growth allowance that can be allocated each year is identified in the applicable ozone maintenance plan.

(iv) The amount of the CO growth allowance that can be allocated is identified in the applicable CO Maintenance Plan, if any.

(d) If no emissions remain in the respective growth allowance or the contingency plan has been triggered which effectively zeros the growth allowance, the owner or operator of the proposed major source or major modification shall provide offsets. Applicants in a maintenance area shall demonstrate the following:

(i) A demonstration shall be provided showing that the proposed offsets will improve air quality in the same geographical area affected by the new source or modification. This demonstration may require that air quality modeling be conducted according to the procedures specified in 40 CFR Part 51, Appendix W, Guideline on Air Quality Models (Revised).

(ii) Offsets for VOCs or nitrogen oxides shall be within the same maintenance plan area as the proposed source. Offsets for particulate matter, PM₁₀, sulfur dioxide, carbon monoxide, nitrogen dioxide, lead, and other pollutants shall be less than the level of significant air quality impact. (Refer to ((~~SWAPCA~~)) SWCAA 400-110 (1)(g) for significance levels).

(iii) New sources or modifications shall meet the following offset requirements:

(A) Within a designated maintenance plan area, the offsets shall provide reductions ((~~which~~)) that are equivalent or greater than the proposed increases. The offsets shall be appropriate in terms of short term, seasonal, and yearly time periods to mitigate the impacts of the proposed emissions;

(B) Outside a designated maintenance plan area, owners or operators of new sources or modifications which have a significant air quality impact on the maintenance plan area as provided in ((~~SWAPCA~~)) SWCAA 400-113(3) shall provide emission offsets which are sufficient to reduce impacts to levels below the significant air quality impact level with the maintenance plan area; and

((~~SWAPCA~~)) SWCAA 400-112 Requirements for New Sources in Nonattainment Areas

[Statutory Authority: Chapter 70.94.141 RCW. Original Board adoption 12/17/68 (Regulation 1 Sec 3); Amended by Board 12/18/79; Amended by Board 8/18/81; Amended by Board 3/20/84; Renumbered from 400-110 93-21-004 filed 10/7/93, effective 11/8/93; 95-17-084 filed 8/21/95, effective 9/21/95; 99-07-028 filed 3/10/99, effective 4/11/99]

A Notice of Construction application to establish a new source or make a modification to a source in a nonattainment area, shall result in the issuance of an Order of Approval or other regulatory order, which contains such conditions as are reasonably necessary to assure the maintenance of compliance with this section, if the ((~~Authority~~)) Agency determines 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, the applicable emission standards of the ((~~Authority~~)) Agency.

(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 must 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 Washington State Implementation Plan and will comply with ((~~SWAPCA~~)) SWCAA 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, and the ((~~Authority~~)) Agency 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 of the pollutant for which the area has been designated nonattainment from the proposed new source or modification are offset by reductions in actual emissions of the pollutant for which the area has been designated nonattainment from existing sources in the nonattainment area 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 emissions units providing the reduction must be less than the current level of actual emissions of that source or emission unit(s). No emission reduction can be credited for actual emissions ((~~which~~)) that 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.

(i) New major sources within a marginal ozone nonattainment area shall:

(A) Offset the new VOC emissions at a ratio of 1.1 to 1, if the VOC emissions exceed either 100 tons per year or 700 pounds per day.

(B) Offset the new NO_x emissions at a ratio of 1.1 to 1, if the NO_x emissions exceed either 100 tons per year or 700 pounds per day.

(ii) Sources within a marginal ozone nonattainment area undergoing major modifications shall:

(A) Offset the entire VOC emissions increase at a ratio of 1.1 to 1, if such increase exceeds either 40 tons per year or 290 pounds per day.

(B) Offset the entire NO_x emissions increase at a ratio of 1.1 to 1, if such increase exceeds either 40 tons per year or 290 pounds per day.

(iii) New major sources within a moderate carbon monoxide nonattainment area shall:

(A) Offset the new carbon monoxide emissions at a ratio of 1 to 1, if the carbon monoxide emissions exceed either 100 tons per year or 700 pounds per day.

(iv) Sources within a moderate carbon monoxide nonattainment area undergoing major modifications shall:

(A) Offset the entire carbon monoxide emissions increase at a ratio of 1 to 1, if such increase exceeds either 100 tons per year or 700 pounds per day.

(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 SWAPCA 400-131 may be used to satisfy some or all of the offset requirements of this subsection.

(6) Noncompliance with any emission limit, test requirement, reporting requirement or other requirement identified in a regulatory order issued pursuant to this section shall be considered a violation of this section.

(7) 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 the EPA-approved Washington State Implementation Plan.

(8) 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 ((~~SWAPCA~~)) SWCAA 400-141 it meets the requirements of that program for all contaminants for which the area has not been designated nonattainment.

(9) If the proposed new source or modification will emit any toxic air pollutants regulated under WAC 173-460, the source meets all applicable requirements of that Chapter.

(10) If the proposed new source is a major stationary source or the proposed modification is a major modification, the ((~~Authority~~)) Agency has complied with the visibility protection review requirements of 40 CFR 52.28 (c) through (h), as in effect on ((~~August~~)) July 1, ((~~1998~~)) 2000, 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 ((~~SWAPCA~~)) SWCAA 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~~)) Agency) processing the Notice of Construction application.

((~~SWAPCA~~)) SWCAA 400-113 Requirements for New Sources in Attainment or Nonclassifiable Areas

Any person proposing to install, construct or operate a new source or emission unit or modification to an existing source or emission unit shall file a Notice of Construction application with the ((~~Authority~~)) Agency and shall be subject to the New Source Review provisions of ((~~SWAPCA~~)) SWCAA 400-110. Confidential information shall be identified as set forth in ((~~SWAPCA~~)) SWCAA 400-270. A Notice of Construction application to establish a new source or make a modification to a source in an area that is in attainment or unclassifiable for any air contaminant the proposed new source would emit and that is in attainment or unclassifiable for ozone if the proposed new or modified source would emit VOCs or NO_x, shall result in the issuance of an Order of Approval or other regulatory order. Such order shall contain such conditions as are reasonably necessary to assure the maintenance of compliance with this section, if it is determined 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 the applicable emission standards of the ((~~Authority~~)) Agency.

(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 or unclassifiable 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 or maintenance plan area does not exceed the following levels for the pollutant(s) for which the area has been designated nonattainment:

Pollutant

((~~SWAPCA~~)) SWCAA 400-114 Requirements for Replacement or Substantial Alteration of Emission Control Technology at an Existing Stationary Source

[Statutory Authority: Chapter 70.94.141 RCW, and 70.94.153 RCW. Original Board adoption 12/17/68 (Regulation 1 Sec 3); Amended by Board 12/18/79; Amended by Board 8/18/81; Amended by Board 3/20/84; Renumbered from 400-110 93-21-004 filed 10/7/93, effective 11/8/93; 95-17-084 filed 8/21/95, effective 9/21/95]

(1) Any person proposing to replace or substantially alter the emission control technology installed on an existing stationary source or emission unit shall file a Notice of Construction application with the ((~~Authority~~)) Agency and shall be subject to the New Source Review process of ((~~SWAPCA~~)) SWCAA 400-110. If the replacement or substantial alteration meets the definition of "new source" or "modification" then the new source emissions standards of ((~~SWAPCA~~)) SWCAA 400-111, 400-112 or ((~~SWAPCA~~)) SWCAA 400-113 shall apply. If the replacement or substantial alteration does not meet the definition of "new source" or "modification" then RACT or other requirements shall apply. Replacement or substantial alteration of control technology does not include routine maintenance, repair or parts replacement.

(2) For projects not otherwise reviewable under ((~~SWAPCA~~)) SWCAA 400-110, the ((~~Authority~~)) Agency may:

(a) Require that the owner or operator employ RACT for the affected emission unit;

(b) Prescribe reasonable operation and maintenance conditions for the control equipment; and

(3) Within thirty calendar days of receipt of a Notice of Construction application under this section the ((~~Authority~~)) Agency shall either notify the applicant in writing that the application is complete or notify the applicant in writing of all additional information necessary to complete the application. Within thirty calendar days of receipt of a complete Notice of Construction application under this section the ((~~Authority~~)) Agency shall either issue an Order of Approval or a proposed RACT determination for the proposed project.

(4) Construction shall not commence, as defined in ((~~SWAPCA~~)) SWCAA 400-030(16), on a project subject to review under this section until the ((~~Authority~~)) Agency issues a final Order of Approval. However, any Notice of Construction application filed under this section shall be deemed to be approved without conditions if the ((~~Authority~~)) Agency takes no action within thirty days of receipt of a complete Notice of Construction application. The ((~~Authority~~)) Agency may request clarification of information submitted in support of the application after the application has been determined to be complete.

(5) An Order of Approval to replace or substantially alter emission control technology shall become invalid if construction is not commenced within eighteen months from the date of issuance of an Order of Approval, if construction is discontinued for a period of eighteen months or more, or if construction is not completed within a reasonable time. The ((~~Authority~~)) Agency may extend the eighteen month period upon a satisfactory demonstration 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. The ((~~Authority~~)) Agency may specify an earlier date for commencement of construction in an Order of Approval.
