(1) Applicability.

(a) All nonroad engine permit applications submitted to the Agency pursuant to SWCAA 400-045 shall be reviewed and processed as described in this section.

(b) Review of a permit application shall be limited to the nonroad engine proposed to be installed, replaced or altered and the air contaminants whose emissions would increase as a result.

(c) The requirements of this section do not apply to "stationary sources" as defined in SWCAA 400-030(115). Permit applications for "stationary sources" are reviewed and processed in accordance with SWCAA 400-110.

(2) Requirements.

(a) Provided that all review requirements are met, a nonroad engine permit shall be issued by the Agency prior to the installation, replacement or alteration of any nonroad engine subject to the requirements of SWCAA 400-045 and this section.

(b) A completed environmental checklist or a completed determination, as provided in Chapter 197-11 WAC, shall be submitted with each application.

(c) Each nonroad engine permit application shall demonstrate that the proposed nonroad engine complies with applicable ambient air quality standards. Regulation of nonroad engines pursuant to this section shall be consistent with Appendix A of 40 CFR 89 Subpart A (as in effect on the date cited in SWCAA 400-025). If the ambient impact of a proposed project could potentially exceed an applicable ambient air standard, the Agency may require that the applicant demonstrate compliance with available ambient air increments and applicable Ambient Air Quality Standards (AAQS) using a modeling technique consistent with 40 CFR Part 51, Appendix W (as in effect on ((July 1, 2015)) the date cited in SWCAA 400-025). Monitoring of existing ambient air quality may be required if data sufficient to characterize background air quality are not available.

(3) Application processing/completeness determination. Within 30 calendar days of receipt of a nonroad engine permit application, the 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.

(4) Final determination.

(a) Within 60 calendar days of receipt of a complete nonroad engine permit application, the Agency shall either issue a final decision on the application or initiate public notice on a proposed decision, followed as promptly as possible by a final decision. All actions taken under this subsection must meet the public involvement requirements of SWCAA 400-171. An owner or operator seeking approval of a project involving applications pursuant to both SWCAA 400-045 and 400-109 may elect to combine the applications into a single permit.

(b) Nonroad engine permits issued under this section 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 Agency.

(c) Nonroad engine permits issued under this section become effective on the date of issuance unless otherwise specified.

(5) Appeals. A nonroad engine permit, any conditions contained in a nonroad engine permit, the denial of a nonroad engine permit application, or any other regulatory order issued pursuant to this section, may be appealed to the Pollution Control Hearings Board within 30 calendar days of receipt as provided in Chapter 43.21B RCW and Chapter 371-08 WAC. The Agency shall promptly mail copies of each nonroad engine permit or order to the applicant and 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.

(6) Compliance. Noncompliance with any term or condition identified in a nonroad engine permit issued pursuant to this section shall be considered a violation of this section.

(7) Expiration. Nonroad engine permits issued pursuant to this section shall become invalid if installation or alteration does not occur within eighteen months after the date of issuance of a permit or if installation or alteration is discontinued for a period of eighteen months or more. The Agency may extend the eighteen-month period upon a satisfactory demonstration that an extension is justified. The Agency may specify an earlier date for installation or alteration in a nonroad engine permit.

If a nonroad engine remains in use at the same location for more than 12 months, approval under this section expires and the nonroad engine becomes a stationary source subject to the provisions of SWCAA 400-109 and 400-110. The owner or operator shall maintain records of the length of use at each location for the purpose of documenting compliance with this requirement.

(8) Change of conditions.

(a) The owner or operator may request, at any time, a change in conditions of an existing nonroad engine permit. The request may be approved provided the Agency finds that:

(i) No ambient air quality standard will be exceeded as a result of the change;

(ii) The change will not adversely impact the ability of the Agency to determine compliance with an applicable permit term or condition; and

(iii) The revised permit meets the requirements of SWCAA 400-046.

(b) A request to change existing approval conditions shall be filed as a nonroad engine permit application. The application shall demonstrate compliance with the requirements of subsection (2) of this section, and be acted upon according to the timelines in subsections (3) and (4) of this section. The current Consolidated Fee Schedule established in accordance with SWCAA 400-098 shall apply to these requests.

(9) Engine registration. The owner or operator of nonroad engines approved pursuant to this section shall notify the Agency within 10 calendar days of engine installation. Subsequent to notification, each permitted unit shall be registered with the Agency and the owner or operator shall pay a registration fee according to the schedule below. Registration expires after a period of 12 consecutive months. If a permitted unit is still operating after its registration expires, it shall be reregistered and a second registration fee, as provided in the current Consolidated Fee Schedule established in accordance with SWCAA 400-098, must be paid.

AMENDATORY SECTION (Amending WSR 16-19-009 filed 9/8/16, effective 10/9/16)

(b) Test methods. Any required emission testing shall be performed using appropriate sampling and analytical methods as approved in advance by the Agency including, but not limited to, approved EPA test methods from 40 CFR Parts 51, 60, 61, and 63 which are hereby adopted by reference (as in effect on ((January 1, 2015)) the date cited in SWCAA 400-025), approved test methods from Ecology's Test Manual Procedures for Compliance Testing, Opacity Determination Method (SWCAA Method 9 - Appendix A to 400), Oregon Department of Environmental Quality (DEQ) Method 8 "Sampling Particulate Emissions from Stationary Sources (High Volume Method)" hereby adopted by reference, or alternate procedures approved by both the Agency and EPA.

(c) Accommodations for sampling. The operator of a "source" shall provide the necessary platform and sampling ports for Agency personnel or others to perform a test of an emission unit. The Agency shall be allowed to obtain a sample from any emission unit. The operator of the "source" shall be given an opportunity to observe the sampling and to obtain a sample at the same time.

(d) Notification/test plan submission. The owner or operator of a "source" shall submit a test plan to the Agency in writing at least 10 business days prior to any required emissions test or as otherwise approved by the Agency. Agency personnel shall be informed at least 3 business days prior to testing so that they have an opportunity to be present during testing.

(e) Test duration. A minimum of 3 test runs, at least 1 hour in length, shall be performed at maximum achievable operating conditions unless otherwise approved in advance to establish that collected data is representative of normal operations. The results of the individual test runs shall be averaged together for the purpose of demonstrating compliance with applicable emission limits.

(f) Test records. A complete record of production related parameters including startups, shutdowns, and adjustments shall be kept during emissions testing to correlate operations with emissions and shall be recorded in the final test report.

(g) Test reports. Results of all required emission testing shall be submitted to the Agency within 45 calendar days of test completion or as specified in the applicable air discharge permit. Test reports shall be submitted in both printed and electronic formats. Measured concentrations for combustion and incineration emission units shall be corrected as provided in the applicable air discharge permit or nonroad engine permit, or as specified in SWCAA 400-050(3). The Agency may reject test reports that do not contain the information listed below, and require resubmittal of a complete report. Test reports shall include the following information:

(i) A description of the emission unit including manufacturer, model number and design capacity of the equipment, and the location of the sample ports or test locations;

(ii) Time and date of the test and identification and qualifications of the personnel involved;

(b) Monitoring method. Emission monitoring may be performed with a portable analyzer or EPA reference methods. Alternative methodologies may be used if approved by both EPA and SWCAA.

(i) For any portable analyzer used to perform emission monitoring pursuant to this section, the response of the analyzer to a calibration gas of known concentration shall be determined before sampling commences and after sampling has concluded. These "calibration error" measurements shall be conducted as close as practical to the time of the monitoring event, but in no case on a different day than the event. At a minimum, the calibration error procedure shall include a two point (zero/span gas) calibration error check using EPA Protocol 1 reference gases. Results of the sampling shall not be valid if the pre and post calibration error check results vary by more than 10 percent of the span value; and

(ii) Span gas concentrations shall be no less than 50 percent and no more than 200 percent of the emission concentration corresponding to the permitted emission limit. When actual emission concentrations are significantly less than the permitted emission limit, a lower concentration span gas may be used if it is more representative of measured concentrations. Ambient air may be used to zero CO and NOx cells/analyzer(s) and span oxygen cells/analyzer.

(c) Accommodations for sampling. The owner or operator of a "source" shall provide the necessary platform and sampling ports for Agency personnel or others to perform monitoring of an emission unit.

(d) Data collection. Emission data shall be collected for at least five minutes following a "ramp-up" phase. The "ramp-up" phase ends when analyzer readings have stabilized (less than five percent per minute change in emission concentration value). Emission concentrations shall be recorded every 30 seconds during data collection. All emission data collected following the ramp-up phase(s) shall be reported to the Agency.

(e) Monitoring records. A complete record of production related parameters shall be kept during emission monitoring to correlate operations with emissions and shall be recorded in the final monitoring report. Typical production parameters include, but are not limited to, startups, shutdowns, unit load, fuel flow, operating temperature, etc.

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. On a permit specific basis, the Agency may specify an earlier date for commencement of construction in an air discharge permit.

The Agency may extend the eighteen-month period upon a satisfactory demonstration that an extension is justified. To obtain an extension the permittee must submit a written request to the Agency at least 60 calendar days prior to permit expiration. The request shall clearly identify the justification for an extension and include relevant supporting information. The Agency will review all submitted information, and then approve or deny the request in writing. If the original permit action required a public comment period pursuant to SWCAA 400-171, the Agency shall provide an additional public comment period prior to approving an extension. An extension for a PSD permit must be approved by Ecology. The extension of a project that is either a major stationary source or a major modification, as those terms are defined in SWCAA 400-810, shall also require determination of LAER as it exists at the time of the extension for the pollutants that were subject to LAER in the original approval.

The Agency may revoke a source's Order of Approval or air discharge permit if applicable registration fees are delinquent for 2 or more consecutive years.

(9) Change of conditions.

(a) The owner or operator may request, at any time, a change in existing approval/permit conditions. The Agency may approve the request provided that:

(i) The change will not cause an applicable emissions standard set by regulation or rule to be exceeded;

(ii) No ambient air quality standard or ambient air increment will be exceeded as a result of the change;

(iii) The change will not adversely impact the ability of the Agency to determine compliance with an emissions standard;

(iv) The revised approval conditions will continue to require BACT, as defined at the time of the original approval, for each approved "stationary source" except where the Federal Clean Air Act requires LAER (e.g., any change that meets the definition of a "new source" must complete a new BACT determination); and

(v) The revised approval conditions meet the requirements of SWCAA 400-110, 400-111, 400-112, 400-113, and 400-830(3) as applicable.

(b) Requests for a change in PSD permit conditions must be made directly to Ecology. The Agency does not have authority to issue or modify PSD permits.

(d) The criteria in 40 CFR 52.21 (r)(4), as adopted by reference in WAC 173-400-720 or SWCAA 400-830(3) as applicable, shall be considered when determining which new source review approvals are required.

(e) A request to change approval/permit conditions shall be filed as an air discharge permit application in accordance with SWCAA 400-109. The application shall meet the requirements of subsection (2) of this section, and be acted upon according to the timelines in subsections (3) and (4) of this section. The fee schedule found in SWCAA 400-109(4) shall apply to these requests.

(10) Reopening for cause. The Agency may, on its own initiative, reopen any order or permit issued pursuant to this section under the following circumstances:

(a) The order or permit contains a material mistake. Typographical errors are presumed to constitute a material mistake.

(b) Inaccurate statements were made in establishing the emission standards and/or conditions of the order or permit.

Reviser's note: The typographical error in the above material occurred in the copy filed by the Southwest Clean Air Agency and appears in the Register pursuant to the requirements of RCW 34.08.040.

AMENDATORY SECTION (Amending WSR 16-19-009 filed 9/8/16, effective 10/9/16)

SWCAA 400-111 Requirements for New Sources in a Maintenance Plan Area

For the purposes of this section, "major modification," "major stationary source," "net emissions increase," and "significant," shall have the same meaning as the definitions found in WAC 173-400-710.

"New sources" or modifications within a designated maintenance plan area, including "stationary sources" that emit VOC or NOx in a designated ozone maintenance plan area, shall meet the following requirements:

(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, National Emission Standards for Hazardous Air Pollutants for Source Categories, emission standards adopted under Chapter 70.94 RCW, and the applicable emission standards of the Agency; and

(b) Not cause any ambient air quality standard as provided in SWCAA 400-113(3) to be violated; 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) Control Technology Requirements - BACT/LAER. Except as provided below, the owner or operator of the proposed "new source", "emission unit" 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. If a violation of an ozone ambient air quality standard or a second violation of the CO ambient air quality standard has occurred, the Agency may require the application of LAER for the maintenance pollutant(s) and any pollutant for which the proposed "new source" or modification is major.

(3) Source compliance. The owner or operator of the proposed "new source", "emission unit" or modification shall certify that all "stationary 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 Chapter 70.94 RCW.

(4) Alternative analysis.

(a) Except as provided in subsection (c) of this section, the owner or operator of a proposed "major stationary 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 "stationary source" or modification that demonstrates that benefits of the proposed "stationary 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 stationary source" or "major modification" that is subject to this rule due to emissions of particulate matter in a designated TSP maintenance area.

(5) Emission offsets and industrial growth allowances. The owner or operator of a proposed new "major stationary source" or "major modification" shall provide emission offsets that satisfy the requirements of this section. Except as provided in subsection (a) of this section, the offset requirements of this section may be met in whole, or in part, by an allocation from an industrial growth allowance, if available. Industrial growth allowances for "stationary sources" in a maintenance plan area are identified in and governed by the Washington SIP and the maintenance plan for the applicable maintenance plan area. All growth allowance allocations for the maintenance plan areas within the Agency's jurisdiction shall be made in accordance with this section.

(a) Available growth allowances may be increased or decreased as provided in a revision to the maintenance plan submitted to and approved by EPA. If a violation of an ozone ambient air quality standard or a second violation of the CO ambient air quality standard has occurred, the Agency may suspend the use of growth allowances, and require the proposed new "major stationary source" or "major modification" to provide offsets as described in subsection (c) below.

(b) The owner or operator of a proposed new "major stationary source" or "major modification" emitting VOCs, NOx, or CO 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 application and allowance allocation request;

(ii) Growth allowances shall be used to satisfy offset requirements at a ratio of 1 to 1 for new VOC and/or NOx emissions.

(iii) No single "stationary source" may receive an emissions allocation of more than 50 percent of the available growth allowance, or up to 10.0 tons per year, whichever is greater. On a case-by-case basis, the SWCAA Board of Directors may approve an emissions allocation of greater than 50 percent upon consideration of the following:

(A) Information submitted by the "stationary source" to SWCAA justifying its request for exceeding the 50 percent emissions allocation, based on significant economic, employment, or other benefits to the maintenance plan area that will result from the proposed new "major stationary source" or "major modification";

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

(iv) To avoid jeopardizing maintenance of the ozone standard during the interim years of the ozone maintenance plan, SWCAA may limit the quantity of VOC and NOx growth allowances made available each year. SWCAA will track use of VOC and NOx allocations from the growth allowances.

(v) The amount of the CO growth allowance that can be allocated is identified in the applicable CO maintenance plan, if any.

(c) If no emissions remain in the respective growth allowance, or the Agency has suspended the use of growth allowances, the owner or operator of the proposed "major stationary source" or "major modification" shall provide offsets.

(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)) as in effect on the date cited in SWCAA 400-025).

(ii) Offsets for VOCs or nitrogen oxides shall be within the same maintenance plan area as the proposed "stationary source." Offsets for particulate matter, PM10, sulfur dioxide, carbon monoxide, nitrogen dioxide, lead, and other pollutants may be from inside or outside of the same maintenance plan area.

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

(A) Within a designated maintenance plan area, the offsets shall provide reductions 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 SWCAA 400-113(3) shall provide emission offsets which are sufficient to reduce impacts to levels below the significant air quality impact level within the maintenance plan area; and

(I) New "major stationary sources" within an ozone maintenance plan 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 NOx emissions at a ratio of 1.1 to 1, if the NOx emissions exceed either 100 tons per year or 700 pounds per day.

(II) "Stationary sources" within an ozone maintenance plan 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 NOx 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 stationary sources" within a carbon monoxide maintenance plan 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) "Stationary sources" within a carbon monoxide maintenance plan 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.

(iv) Emission reductions shall be of the same type of pollutant as the emissions from the "new source" or modification. Sources of PM10 shall be offset with particulate in the same size range.

(v) Emission reductions shall be contemporaneous, that is, the reductions shall take effect prior to the time of startup but not more than two years prior to the submittal of a complete application for the "new source" or modification. This time limitation may be extended through banking, as provided in SWCAA 400-130, 400-131 and 400-136 for banking activities approved after the effective date of this regulation. In the case of replacement facilities, SWCAA may allow simultaneous operation of the old and new facilities during the startup period of the new facility provided that emissions do not exceed the new emission limits.

(vi) Offsets for new "major stationary sources" or "major modifications" in a maintenance plan area shall meet the following requirements:

(A) The proposed new level of allowable emissions of the "stationary source" or emission unit providing the reduction must be less than the current level of actual emissions of that "stationary source" or emission unit. No emission reduction can be credited for actual emissions that exceed the current allowable emissions of the "stationary source" or emission unit providing the reduction. Emission reductions imposed by local, state, or federal regulations, regulatory orders or permits cannot be credited.

(B) If the offsets are provided by another "stationary source," the reductions in emissions from that "stationary source" must be federally enforceable by the time the new or modified "stationary source" commences operation. The "new source" may not commence operation before the date such reductions are actually achieved. SWCAA may allow simultaneous operation of the old and new facilities during the startup period of the new facility provided that the facilitywide emissions do not exceed the new emission limit.

(6) PSD applicability. 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 as described in WAC 173-400-700 through 173-400-750, the "new source" or modification shall meet the requirements of that program for all pollutants. For maintenance plan pollutants, the "new source" shall meet all PSD requirements in addition to the requirements of this section.

(7) Toxics. If the proposed "new source" or modification will emit any toxic air pollutants regulated under Chapter 173-460 WAC (as in effect 8/21/98), the "new source" shall meet all applicable requirements of that regulation.

(8) Visibility. If the proposed "new source" is a "major stationary source" or the proposed modification is a "major modification," the "new source" shall meet all the visibility protection requirements of WAC 173-400-117.

(9) Noncompliance. 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.

AMENDATORY SECTION (Amending WSR 16-19-009 filed 9/8/16, effective 10/9/16)

APPENDIX A

SWCAA METHOD 9

VISUAL OPACITY DETERMINATION METHOD

1. Principle

The opacity of emissions from stationary sources is determined visually by a qualified observer.

2. Procedure

The observer must be certified in accordance with the provisions of Section 3 of 40 CFR Part 60, Appendix A, Method 9((,)) (as in effect on ((July 1, 2015)) the date cited in SWCAA 400-025).

2.1 Position

The observer shall stand at a distance sufficient to provide a clear view of the emissions with the sun oriented in the 140° sector to his/her back. Consistent with maintaining the above requirement, the observer shall, as much as possible, make his/her observations from a position such that his/her line of vision is approximately perpendicular to the plume direction, and when observing opacity of emissions from rectangular outlets (e.g., roof monitors, open baghouses, noncircular stacks), approximately perpendicular to the longer axis of the outlet. The observer's line of sight should not include more than one plume at a time when multiple stacks are involved, and in any case, the observer should make his/her observations with his/her line of sight perpendicular to the longer axis of such a set of multiple stacks (e.g., stub stacks on baghouses).

2.2 Field Records

The observer shall record the name of the plant, emission location, type of facility, observer's name and affiliation, a sketch of the observer's position relative to the source, and the date on a field data sheet. The time, estimated distance to the emission location, approximate wind direction, estimated wind speed, description of the sky condition (presence and color of clouds), and plume background are recorded on a field data sheet at the time opacity readings are initiated and completed.

2.3 Observations

Opacity observations shall be made at the point of greatest opacity in that portion of the plume where condensed water vapor is not present. The observer shall not look continuously at the plume, but instead shall observe the plume momentarily at 15-second intervals.

2.3.1 Attached Steam Plumes

When condensed water vapor is present within the plume as it emerges from the emission outlet, opacity observations shall be made beyond the point in the plume at which condensed water vapor is no longer visible. The observer shall record the approximate distance from the emission outlet to the point in the plume at which the observations are made.

2.3.2 Detached Steam Plumes

When water vapor in the plume condenses and becomes visible at a distinct distance from the emission outlet, the opacity of emissions should be evaluated at the emission outlet prior to the condensation of water vapor and the formation of the steam plume.

2.4 Recording Observations

Opacity observations shall be recorded to the nearest 5 percent at 15-second intervals on a field data sheet. A minimum of 24 observations shall be recorded. Each momentary observation recorded shall be deemed to represent the average opacity of emissions for a 15-second period.

2.5 Data Reduction

The number of observations at each opacity level shall be determined and recorded on the field data sheet. Opacity shall be determined by the highest 13 observations in any consecutive 60-minute period. The opacity standard or emissions limit is exceeded if there are more than 12 observations during any consecutive 60-minute period for which an opacity greater than the standard or emission limit is recorded. The opacity standard is a 1 hour standard (rolling 60 minutes). Only one violation of the standard per hour may be recorded meaning that a violation for any given consecutive 60-minute period may be recorded in substantially fewer than 60 minutes. No one-hour time sets shall overlap for purpose of determining a violation or violations. Data used to establish a violation in one consecutive 60-minute period can not be used to establish a violation in a second consecutive 60-minute period.

Notes: (1) The difference between the SWCAA Method 9 and WDOE Method 9 or WDOE Method 9A is the SWCAA method does not recommend that the observer make note of the ambient relative humidity, ambient temperature, the point in the plume that the observations were made, the estimated depth of the plume at the point of observation, and the color and condition of the plume. In addition, the SWCAA method does not recommend that pictures be taken.

(2) The difference between the SWCAA Method 9 and EPA Method 9 is in the data reduction section. The SWCAA method establishes a three-minute period in any one-hour period where opacity can not exceed an opacity limit. For the SWCAA method, 13 readings in a 1-hour period or less, above the established opacity limit, no matter how much, constitutes a violation. The EPA method is an arithmetic average of any 24 consecutive readings at 15-second intervals. These values are averaged and this average value cannot exceed the established opacity limit.
