Project Description

US Electrodynamics, Inc.

Project Description

Background:

US Electrodynamics, Inc. (USEI) provides government and commercial satellite teleport services

including TT&C (tracking, telemetry, and command), broadcast video, aviating, and internet

services delivery. USEI is headquartered and operates a teleport facility at 66C Teleport Drive in

Brewster, Washington. The facility has emergency power supply via six diesel-fired emergency

generators which are permitted under Washington State Department of Ecology’s Central Region

Office (Ecology – CRO) Notice of Construction No. 09AQ-C085, 2nd revision. USEI intends to

add three additional 1.5-MW diesel-fired emergency generators to support work the local Public

Utility District is doing to add an additional sub station and feed the facility.

Project Description:

USEI intends to install three 1.5-MW Cummins 1500DQGAB diesel-fired emergency

generators. Only two of the three generators will ever operate simultaneously. Two 20,000-

gallon diesel storage tanks will be installed along with the three emergency generators. See

Attachment 1-3 for a facility map with the location of the three generators and the two 20,000-

gallon diesel storage tanks highlighted in yellow.

Emission Sources:

The three Cummins generators will be powered with diesel fuel with a maximum sulfur content

of 15 ppm. Criteria pollutants potential to emit (PTE) were calculated using manufacturer data

(see Attachment 4). Particulate emissions include both the manufacturer’s particulate emission

factor and hydrocarbon emission factor. Diesel engine particulate (DEEP) is considered a toxic

air pollutant (TAP) in the state of Washington, and is calculated based on the manufacturer’s

PM2.5 emission factor, excluding hydrocarbons. Nitrogen dioxide (NO2) is also considered a

TAP, and is calculated based on the manufacturer nitrous oxide (NOX) emission factor. Other

TAP emissions were calculated using emission factors from AP-42 Chapter 3.4.

The generators will operate between 40% and 90% load during both testing and emergency

scenarios. To be conservative, manufactures data at 25% and 100% load were used for the

emission inventory and modeling. Values in between were not evaluated since the two extremes

account for the worst-case emissions. To be conservative, the highest load value for each

pollutant will be used for the PTE calculations. Emissions were calculated and modeled based on

73 hours of operation per generator per year for an aggregate of 219 hours per year between the

three generators. The calculations and modeling assume two generators operating for short-term

averaging and aggregate for long-term averaging. Standby performance data was used in the

emissions calculations rather than prime data since emergency generators fit the standby

designation.

Federal Rule Applicability:

• USEI is an area source of hazardous air pollutants (HAPs) and non-major source

of criteria pollutants. The facility is unchanged based on this project.

• New Source Performance Standard (40 CFR 60) Subpart IIII is applicable to this

project.

US Electrodynamics, Inc. NOC Application - 2021 Generator Installation x3

December 29, 2020 Attachment 1-1

• National Emission Standards for Hazardous Air Pollutants (40 CFR 63) Subpart

ZZZZ is applicable to this project.

Project Timeline:

• The gensets are tentatively scheduled for delivery March 1, 2021.

• Commissioning the units is tentatively scheduled for April 1-15, 2021.

Operations Schedule:

The generators will operate for an aggregate maximum of 219 hours per year (approximately 73

hours per unit. Fuel consumption at 100% load is defined by the manufacturer at 108 gallons of

diesel per hour per generator.

Introduction

US Electrodynamics, Inc. (USEI) operates a teleport services facility under Approval Order No. 09AQ-

C085, 2nd revision in Okanogan County, Washington. USEI has emergency power supply via six diesel

fired emergency generators, and proposes to add three additional diesel-fired emergency generators for

a project with the Okanogan Public Utility District (PUD).

Two pollutants emitted during diesel fuel combustion of the three new emergency generators at the

facility trigger tBACT.

Regulated Emissions

Emissions of the following toxic pollutants are greater than the de minimis of WAC 173-460-150 and

will be the subject of this tBACT analysis:

• Diesel engine exhaust, particulate (DEEP)

• Nitrogen dioxide (NO2)

Step 1: Identify Technologies

Under the State of Washington’s NSR rules, which are promulgated and enforced by Ecology and local

air quality districts, best available control technologies (BACT) are required for construction and

modification of specified stationary sources.

BACT is defined as an emission limitation (including a visible emission standard) based on the maximum degree of reduction

for each pollutant subject to regulation under the Clean Air Act which would be emitted from any proposed

major stationary source or major modification which the Administrator, 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 or available methods, systems,

and techniques, including fuel cleaning or treatment or innovative fuel combustion techniques for control

of such pollutant.1

The purpose of this investigation was to identify potential control technologies for controlling emissions

from the diesel fuel combustion.

Control techniques for criteria pollutants may be classified into two broad categories – (1) inherently

lower emitting processes/practices and (2) emission controls2.

The control techniques potentially available for control of DEEP emissions from diesel fuel combustion

include:

o Inherently lower emitting process/practices

o Good combustion practices

o Emission controls

o Diesel oxidation catalyst (DOC)

o Diesel particulate filters (DPF)

The control techniques potentially available for control of NO2 emissions from diesel fuel combustion

include: o Inherently lower emitting process/practices

o Injection Timing Retardation (ITR)

o Air-to-fuel ratio adjustment

o Derating

o Post-combustion controls

o Selective Non-catalytic reduction (SNCR)

o Selective catalytic reduction (SCR)

DEEP Combustion Emissions Based on proposed maximum throughput, the facility has the potential to emit 59.0 pounds per year of

DEEP from combustion emissions.

Step 2: Infeasible Technologies

None of the technologies are infeasible.

Step 3: Effectiveness Ranking

According to the 1990 Draft New Source Review Manual, feasible technologies are next ranked by the

degree of reduction (i.e. “% reduction).

Based on 2010 technical bulletins from EPA on pages 5-7 through 5-10 of this report, the control

efficiencies are as follows:

Type of Control % Reduction

PM

Potential Emissions

DEEP (lbs/yr)

Diesel Particulate Filter (DPF) 85-90% 5.9 – 8.9

Diesel Oxidation Catalyst (DOC) 20-40% 35.4 – 47.2

None 0% 59.0

Step 4: Evaluate Controls

Spring Environmental obtained a cost estimate from Nett Technologies for a DPF and DOC and the

estimate is included in pages 5-11 and 5-12 of this report. Capital costs were estimated by multiplying

the cost estimates from Nett Technologies by 3 to account for the three generators included in Spring

Environmental’s DEEP emission calculations. Annual capital costs were estimated assuming an

equipment life of 10 years and an interest rate of 7%. Annual labor costs for the DPFs were calculated

using wages from the U.S. Bureau of Labor Statistics. DOCs require little to no maintenance, hence

minimal operation and maintenance cost. The detailed cost analysis is included in page 5-6 of this report.

Notes:

1. Capital cost is for three installations of a particular piece of control equipment, as there are three

generators that emit DEEP emissions.

Step 5: BACT Recommendation

Spring Environmental recommends that DPF and DOC controls are not cost effective for USEI’s

operations.

NO2 Combustion Emissions Based on the proposed operating hours, the facility has the potential to emit 2.88 tons per year of NO2

from combustion of diesel fuel.

Step 2: Infeasible Technologies

• ITR has rarely been applied to either small or large internal combustion engines. Although ITR

reduces NO2 emissions, it correspondingly reduces engine power, which is necessary for facility

operations in an emergency situation.

• Air to fuel ratio adjustment has not been applied to either small or large internal combustion

engines per the EPA RACT/BACT/LAER Clearinghouse (RBLC). The generators will operate

according to manufacturer specifications.

• Derating is not a feasible pollution prevention strategy because the current capacity of the

generators is necessary for facility operations in an emergency situation. Only two of the

generators will operate at a time.

• SCR has not been applied to either small or large internal combustion engines per the EPA

RBLC. Although the technology may be feasible, it is not demonstrated technology for the size

of the generators under consideration. Personnel and environmental risks related to the storage

and management of ammonia far outweigh the benefits of reducing 2.88 tons of NO2 per year.

• SNCR has not been applied to either small or large internal combustion engines per the EPA

RBLC. Although the technology may be feasible, it is not demonstrated technology for the size

of the generators under consideration. Personnel and environmental risks related to the storage

and management of ammonia far outweigh the benefits of reducing 2.88 tons of NO2 per year.

Step 3: Evaluate Controls

According to EPA’s RBLC, there are no proven NO2 control technologies for emergency internal

combustion engines. The generators will operate according to manufacturer specifications with limited

operating hours, only running two of the three generators at a time.

Step 4: BACT Recommendation

Spring Environmental recommends that operating according to manufacturer specification and limited

operation is BACT for control of NO2 from combustion.

Summary

Spring Environmental recommends that BACT be defined as operating according to manufacturer specification and limited operation for control of NO2 from diesel combustion. NOx emissions would be a maximum of2.88 tpy.

Spring Environmental recommends that DPF and DOC controls for DEEP are not cost effective for USEI. DEEP emissions would be a maximum of59.0 lbs/year.

Diesel Oxidation CatalystGeneral Information

Technical Bulletin

Technical Overview Diesel Oxidation Catalysts, also known as DOCs, are exhaust aftertreatment devices that reduce emissions from diesel fueled vehicles and equipment. Engine manufacturers have used DOCs in different in-use applications for many years, and DOCs are widely used as a retrofit technology because of their simplicity and limited maintenance requirements. DOCs generally consist of a precious metal coated flow-through honeycomb structure contained in a stainless steel housing. As hot diesel exhaust flows through the honeycomb structure, the precious metal coating causes a catalytic reaction that breaks down pollutants into less harmful components.

Emissions Reduction The United States Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) evaluate the emission reduction performance of DOCs and identify engine operating criteria and conditions that must exist for DOCs to achieve those reductions.

DOCs verified by EPA and CARB are typically effective at reducing emissions of particulate matter (PM) by 20 to 40 percent. EPA’s Verified Technology List also shows that DOCs may reduce hydrocarbons by 40 to 75 percent and carbon monoxide by 10 to 60 percent. The PM removed by DOCs is largely the soluble organic fraction that comes from unburned fuel and oil. DOCs generally

have little impact on elemental carbon and oxides of nitrogen (NOx) emissions. DOCs have also been verified in combination with crankcase ventilation systems for additional emissions reduction.

EPA is aware of concerns that DOCs may increase the nitrogen dioxide (NO2) fraction of total NOx emissions. The NO2 produced by a DOC is dependent on the catalyst formulation. EPA and CARB have established a limit on increases in NO2 emissions from diesel retrofit devices and all DOCs on the lists of verified products comply with this limit.

Application Verified DOCs are available for nonroad and highway heavy-duty diesel engines including those on buses, school buses, trucks, mining equipment, construction equipment, cargo handling equipment, marine vessels, auxiliary power units and stationary generators.

Each DOC is verified for use with specific engines and/or with specific configurations over a range of model years. In addition to vehicle and engine specifications, the intended application should be evaluated for exhaust temperature, fuel sulfur levels and lubrication oil consumption. EPA and CARB’s lists of verified diesel retrofit technologies define the specific engine operating criteria required to successfully apply a particular retrofit technology: www.epa.gov/otaq/retrofit/verif-list.htm.

Fuel DOCs perform best with Ultra Low Sulfur Diesel fuel (ULSD), and some DOCs are verified for use with Low Sulfur Diesel (LSD). ULSD, which contains up to 15 parts per million sulfur, is required for highway vehicles and will begin to be phased in for the nonroad sector beginning in 2010.

EPA is aware of concerns that DOCs may release some ultrafine particulates. Such concerns are associated with high sulfur levels in diesel fuel and the potential for sulfur

December 29, 2020 Attachment 5-7

to accumulate in the DOC and then be released as sulfate particles. This characteristic may also be associated with the precious metal loading and vehicle operation. When used with ULSD EPA does not believe DOCs increase ultrafine PM. Although nonroad diesel fuel will not be required to meet ULSD sulfur levels until 2010, nonroad equipment equipped with DOCs should preferably be fueled with ULSD.

Cost DOCs generally cost between $600 to $2,000 or more, including installation, depending on engine size, installation requirements or other unique needs. Because a DOC is likely to be heavier than a muffler, it is likely that special mounting is necessary.

LongevityWhen properly installed and maintained, DOCs should remain effective for the life of the vehicle, generally five to ten years or 10,000 or more hours of operation. Engine problems with fuel control or oil consumption may quickly deteriorate the performance of a DOC. Consequently, regular engine maintenance is essential to DOC performance.

Warranty coverage is typically part of the commercial contract negotiated between the product suppliers and their customers. Such warranties typically cover defects in materials or workmanship for a specified period defined in years, miles and/or operating hours.

As part of their verification program, CARB has established detailed warranty periods for CARB-verified retrofit technologies as shown in the following table.

Diesel Particulate FilterGeneral Information

Technical Bulletin

Technical Overview Diesel Particulate Filters, also known as DPFs, are exhaust aftertreatment devices that significantly reduce emissions from diesel fueled vehicles and equipment. DPFs typically use a porous ceramic or cordierite substrate or metallic filter, to physically trap particulate matter (PM) and remove it from the exhaust stream.

After it is trapped by the DPF, collected PM is reduced to ash during filter regeneration. Regeneration occurs when the filter element reaches the temperature required for combustion of the PM. “Passive” regeneration occurs when the exhaust gas temperatures are high enough to initiate combustion of the accumulated PM in the DPF, without added fuel, heat or driver action. “Active” regeneration may require driver action and/or other sources of fuel or heat to raise the DPF temperature sufficiently to combust accumulated PM. The frequency of regeneration is determined by the engine’s duty cycle, PM emission rate, filter technology and other factors. When using an active filter, it is particularly important to follow the manufacturer’s instructions for regeneration.

In addition to regeneration, the filter must be periodically cleaned to remove noncombustible materials and ash. It is important to avoid excessive PM and ash accumulation in a DPF, so proper maintenance and cleaning instructions should be followed closely. Cleaning of DPFs is typically

required every 6 to 12 months. The cleaning process involves manually removing the filter element from the vehicle and placing it in a cleaning station designed for this purpose. An engine emitting excessive PM or inadequate filter regeneration will cause a DPF to require more frequent cleaning. Diagnostics should be performed to identify the cause for more frequent cleaning intervals. A backpressure monitoring system should always be used with a DPF and periodic inspection of the monitoring system should be performed to confirm proper operation.

Emissions Reduction The United States Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) evaluate the emission reduction performance of DPFs and identify engine operating criteria and conditions that must exist for DPFs to achieve those reductions.

DPFs verified by EPA and CARB are typically effective at reducing emissions of PM by 85 to 90 percent or more. EPA’s Verified Technology List also shows that certain DPFs reduce emissions of hydrocarbons and CO by 70 to 90 percent. DPFs generally do not reduce oxides of nitrogen (NOx) emissions. DPFs can be combined with crankcase ventilation systems for additional emission reductions.

EPA is aware of concerns that catalyzed DPFs may increase the nitrogen dioxide (NO2) fraction of total NOx emissions. Some DPFs generate NO2 as a means to help filter regeneration at lower temperatures. The NO2 produced by a DPF is dependent on the catalyst formulation. EPA and CARB have established a limit on increases in NO2 emissions from diesel retrofit devices and all DPFs on the lists of verified products comply with this limit.

ApplicationVerified DPFs are available for nonroad and highway heavy-duty diesel engines including those on buses, trucks, construction equipment, auxiliary power units and stationary generators.

Each DPF is verified for use with specific engines and/or with specific configurations over a range of model years. In addition to vehicle and engine specifications, the intended application should be evaluated for exhaust temperature, duty cycle, fuel sulfur levels, lubrication oil consumption and engine-out PM emission levels. Exhaust temperature data logging should be performed with each installation over a range of vehicle duty cycles and, if possible, over a range of ambient temperatures. A copy of results and analysis from data logging should be retained by the fleet for each installation. EPA and CARB’s lists of verified diesel retrofit technologies define the specific engine operating criteria required to successfully apply a particular retrofit technology: www. epa.gov/otaq/retrofit/verif-list.htm.

Fuel DPFs are verified for use with Ultra Low Sulfur Diesel fuel (ULSD), which contains up to 15 parts per million sulfur. Fuel additives should not be used unless explicitly approved by the DPF manufacturer.

Cost DPFs generally cost between $5,000 to $15,000 or more, including installation, depending on engine size, filter technology and installation requirements. Active DPF systems are more expensive than passive DPF systems and can cost up to $50,000 for a large piece of nonroad equipment. Vehicle inspection, data logging and backpressure monitoring systems are required with each installation and these costs are typically included in the cost of the DPF. Because a DPF is likely to be heavier than a muffler, it is likely that special mounting is necessary. Costs for cleaning stations or cleaning services should also be considered when purchasing DPFs.

Longevity When properly installed and maintained, DPFs should remain effective for the life of the vehicle, generally five

to ten years or 10,000 or more hours of operation. Engine problems with fuel control or oil consumption may quickly deteriorate the performance of a DPF. Consequently, regular engine maintenance is essential to DPF performance.

Warranty coverage is typically part of the commercial contract negotiated between the product suppliers and their customers. Such warranties typically cover defects in materials or workmanship for a specified period defined in years, miles and/or operating hours.

Hello David Thanks for your interest in Nett Technologies as an emission solution provider. I can give you some ballpark numbers for the DOC as well as DPF systems but keep in mind that on an engine this size there may be configuration issues to deal with especially on the multiple DPF assembly required to address exhaust flow on an engine this size. You could expect approximately $6000.00 USD for the DOC assembly and for a DPF approximately $30,000.00 USD plus the installation costs. The DPF would require 4 elements and would need to be configured so the cores can be accessed for servicing. In addition a temperature profile of the engine in service is recommended to assure adequate temperature for regeneration. I hope this rough estimate is suitable for your needs. Please let me know if you have any questions. Regards Wayne Moffat, Senior Technical Sales Sales Department wmoffat@nettinc.com

AIR DISPERSION MODELING US ELECTRODYNICS – GENSETS X 3

US Electrodynamics, Inc. (USEI) provides government and commercial satellite teleport services

including TT&C (tracking, telemetry, and command), broadcast video, aviating, and internet

services delivery. USEI is headquartered and operates one of two teleport facilities at 66C Teleport

Drive in Brewster, Washington. The facility has emergency power supply via six diesel-fired

generators, which are permitted under Washington State Department of Ecology’s Central Region

Office (Ecology-CRO) Notice of Construction No. 09AQ-C085, 2nd revision. USEI intends to add

three additional 1.5 MW diesel-fired emergency generators to support work the local Public Utility

District is doing to add an additional sub station and feed the facility. USEI has engaged Spring

Environmental to prepare an NOC application package and complete the air dispersion modeling

analysis. Spring Environmental submitted a modeling protocol on November 11, 2020 to Ranil

Dhammapala, atmospheric scientist with Ecology, and received comments from Tes Ghidey, Ryan

Vicente, and Gary Palcisko on 12/10/2020. The modeling was updated accordingly. The following

is a summary of the air dispersion analysis.

1. Purpose

To determine the potential impact of the proposed project in relation to the acceptable source impact

level (ASIL) for toxic air emissions per WAC 176-460-150.

2. Model Description

EPA provides guidance in Subpart W of 40 CFR Part 51 on applicability of specific air quality

dispersion models in the review and preparation of new source permits and State Implementation

Plans (SIP) revisions. Based on the topography, land use, and meteorology, AERMOD was

selected to model the air emissions.

The American Meteorological Society/Environmental Protection Agency Regulatory Model

(AERMOD) is a steady-state Gaussian plume model which can be used to assess pollutant

concentrations from a wide variety of sources. AERMOD utilizes surface boundary layer parameters

and meteorological data profiles calculated by AERMET, which processes hourly surface observations

and upper air data. AERMAP is a terrain preprocessor for AERMOD.

AERMOD: Since AERMOD was specifically developed to support EPA’s regulatory modeling

programs, the regulatory modeling options, as specified in the Guideline of Air Quality Models

(Revised), are the default mode of operation for the generator model. These options include a routine

for processing averages when calm winds or missing meteorological data occur.

The user may select either rural or urban dispersion parameters, depending on the characteristics of the

source location. The user also has the option of calculating several short-term (1-, 2-, 3-, 4-, 6-, 8-, 12-,

or 24-hr) averages in addition to long term (monthly, annual, or period) averages for concentration

values or deposition values for a particular run.

The model is capable of handling multiple sources, including point, volume, and area source types. Line

sources may also be modeled using a string of volume or area sources. Several sources and groups of

US Electrodynamics December 2020

Air Dispersion Modeling Report Page 2

sources may be specified in a single run. The emission rates of the sources can be treated as constant or

varied according to time of day, month or season.

The user has the capability of specifying multiple receptor networks in a single run, and may mix

Cartesian grid receptor networks and polar grid receptor networks. This is useful for applications where

the user may need a coarse grid over the entire modeling domain, but a denser grid in the area of

maximum expected impacts. The user has the option of specifying receptor elevations above ground to

model flagpole receptors. Receptor elevations and hill height scales are calculated by AERMAP from

USGS Digital Elevation Model files. In AERMOD, there is no distinction between elevated terrain

below release height and terrain above release height as with earlier regulatory models that distinguished

between simple and complex terrain.

The user has various options of printed output including summaries of high values, summaries of overall

maximum values and tables of multiple receptors for each averaging period and source group

combinations. The latter group of data may be used to generate contour and grid maps.

The latest version of AERMOD (19191) was used in the air dispersion modeling analysis for USEI’s

three emergency diesel generators. Further information is available in the User’s Guide in the EPA

Guidance of Air Quality Models.

AERSURFACE: When applying the AERMET meteorological processor, the user must determine

appropriate values for three surface characteristics: surface roughness length, noontime albedo, and

daytime Bowen ratio. The AERSURFACE tool aids users in obtaining realistic and reproducible surface

characteristic values for the three surface characteristics. The tool uses data from the National Land

Cover Database (NLCD) from the United States Geological Survey (USGS) and look-up tables of

surface characteristic values that vary by land cover type and season.

The latest version of AERSURFACE (20060) was used in the air dispersion modeling analysis for the

ACRL. Further information is available in the User’s Guide in the EPA Guidance of Air Quality

Models.

AERMET: Surface observations are available from meteorological towers operated by various

agencies including local environmental agencies and the National Weather Service of the National

Oceanic & Atmospheric Administration (NOAA). Remote Automatic Weather Stations (RAWS) is a

network of automated weather stations run by the U. S. Forest Service and the Bureau of Land

Management (BLM) and monitored by the National Interagency Fire Center. National Weather Service

stations are usually located at significant airports while RAWS data is often located in remote areas.

Upper air data is also collected by NOAA’s National Weather Service and stored in the NOAA Forecast

Systems Laboratory Radiosonde Database (http://raob.fsl.noaa.gov). See Section 6 for more

information about the data selected for this modeling demonstration.

There are three stages to processing meteorological data. The first stage extracts meteorological data

from archive data files and processes the data through various quality assessment checks. The second

stage merges all data available for 24-hour periods (NWS and site-specific data) and stores these data

together in a single file. The third stage reads the merged meteorological data and estimates the

necessary boundary layer parameters for use by AERMOD. Two files are written for AERMOD: a file

of hourly boundary layer parameter estimates and a file of multiple-level observations of wind speed

and direction, temperature, and standard deviation of the fluctuating components of the wind.

US Electrodynamics December 2020

Air Dispersion Modeling Report Page 3

AERMINUTE was used to process 1-minute wind data which helps reduce the number of calms and

missing winds in the surface data.

The latest version of AERMET (19191) was used to assess the meteorological data for USEI. Further

information is available in the User’s Guide for the AERMOD Meteorological Pre-processor.

AERMAP: AERMAP processes commercially available Digital Elevation Data and creates a file

suitable for use within an AERMOD control file. See Sections 4 and 5 for more information about the

data selected for this modeling demonstration. This file would contain elevation and hill-height scaling

factors for each receptor in the air dispersion study. AERMAP can also calculate the base elevations of

the sources.

For complex terrain situations, AERMOD captures the essential physics of dispersion in complex

terrain and therefore needs elevation data that conveys the features of the surrounding terrain. In

response to this need, AERMAP searches for the terrain height and location that has the greatest

influence on dispersion for each individual receptor. This height is the referred to as the hill height scale.

Both the base elevation and hill height scale data are produced by AERMAP as a file or files which can

be directly inserted into an AERMOD input control file. Further information is available in the User’s

Guide for the AERMOD Terrain Pre-processor.

Process Overview

USEI intends to install three Cummins 1500DQGAB diesel-fired emergency generators. See

Appendix A for a facility map with the location of the three generators. Each generator will

operate approximately 73 hours per year, for an aggregate total of 219 hours per year. Only two of

the three generators will ever operate simultaneously. The generators will be installed upon

approval of this application.

Emissions Data

Based on preliminary emissions calculations, diesel engine particulate matter (DEEP) and nitrogen

dioxide NO2 are the only toxic air pollutants with emissions estimated to exceed de minimis and

small quantity emission rate (SQER) levels defined in WAC 173-460-150. Therefore, DEEP and

NO2 require modeling. NO2 is the only criteria pollutant to have emissions estimated to exceed de

minimis levels defined in WAC 173-400-110(5). Therefore, 1-hr and annual NO2 require

modeling.

Potential emissions from the generators were calculated using the operational specifications of the

Cummins 1500DQGAB generators. USEI expects the generators to operate between 40% and 90%

load during both testing and emergency scenarios, but 25% and 100% loads were used for this

analysis for a safety factor. Values in between were not evaluated since the two extremes account

for the worst-case emissions. The maximum DEEP emissions occur at 25% load, and the

maximum NO2 emissions occur at 100% load. Only two of the three generators will operate

simultaneously; two of the generators are backup generators. Emissions were calculated and

modeled based on 73 hours of operation per generator per year for a total of 219 hours per year.

Emissions estimates were developed by using emissions data provided by the manufacturer, and

from AP-42 Section 1.3 when equipment specific factors are not available. A summary of criteria

pollutants that have the potential to exceed the de minimis level can be found in Table 1. A

summary of TAPs that have the potential to exceed their respective SQER can be found in Table

2.

Modeling Parameters

Modeling was performed for two scenarios: the generators operating at 25% load and at 100% load.

The worst-case impacts were compared to their corresponding acceptable source impact levels (ASIL). The default ARM2 method will be used for NO2 modeling. Per the EPA AERMOD User’s Guide

Addendum section 3.3.6.3, the default upper and lower limits on the ambient ratio applied to the

modeled NO2 concentrations are 0.9 and 0.5 respectively.

Each generator was modeled as an individual point source. Table 2 presents a summary of the point

source modeling parameters used for each generator. These parameters are consistent with manufacturer

specifications and USEI’s installation plans.

a. No correction was made to stack width for stack cap. Per discussion with Ecology, issues have been identified at or below 10% load. USEI

will not operate at loads below 25% and has a hinged stack cap that will open to a 45° angle or greater when the equipment is in operation. b. A 5% correction factor was applied to stack temperatures and flow rates from the manufacturers specifications per discussion with Ecology

to account for low ambient temperatures for part of the year.

4. Receptor Network

A receptor flagpole height of 1.5 meters was used in the analysis. The ambient air boundary was

considered to be the site boundary and the receptor grid extends beyond that. USEI is fenced to prevent

public access. A receptor grid was established based on Ecology’s “Guidance Document; First, Second,

and Third Tier Review of Toxic Air Pollutant Sources”.

• 12.5-m spacing from the source out to 150 meters

• 25-m spacing from 150 to 400 meters

• 50-m spacing from 400 to 900 meters

• 100-m spacing from 900 to 2,000 meters

• 300-m spacing from 2,000 to 4,500 meters

• 600-m spacing from 4,500 meters to 10,000 meters

US Electrodynamics December 2020

Air Dispersion Modeling Report Page 6

5. Elevation Data

Spring Environmental ran AERMAP (version 18081) for the area and point sources and all receptors

using a NED file (datum NAD 83) covering the area between 47.875 to 48.50 degrees North latitude

and 119.25 to 120.125 degrees West longitude. Terrain data was obtained from the following website:

https://viewer.nationalmap.gov/basic/ and converted from the ArcGrid format to the GeoTIFF format.

Coordinates, elevations, hill heights, and flagpole heights for all receptors (datum WGS 84) are included

in the AERMOD input file (Appendix B).

6. Surface Data

Spring Environmental ran AERSURFACE (version 20060) to process land cover data to determine the

surface characteristics for use in AERMET. Landcover, impervious, and tree canopy data was obtained

from the following website: https://www.mrlc.gov/viewer/.

7. Meteorological Data

Per Ecology’s response to the modeling protocol, a Remote Automatic Weather Station (RAWS)

is available near the site. The station E6379 is located about 2 miles northwest of the site. Spring

Environmental downloaded the RAWS data from https://developers.synopticdata.com/ and

performed basic quality control on the data. The National Weather Service (NWS) data from the

Omak Airport was used to fill in any missing variables in the RAWS data. Spring Environmental

used RAWS data for years 2015-2019 from E6379 as “on-site” data in AERMET.

Supplemental surface data and one-minute ASOS data from the Omak Airport, station ID 94197, were

used to fill in missing information from the RAWS on-site data. The surface data was obtained at

ftp://ftp.ncdc.noaa.gov/pub/data/noaa and the one-minute ASOS data was obtained at

ftp://ftp.ncdc.noaa.gov/pub/data/asos-onemin/. Upper air data was obtained from Spokane International

Airport, site ID 04106, at http://esrl.noaa.gov/raobs/. Both stations are believed to be the best available

data for the Brewster area.

8. Land Use Classification

Most of the immediate area surrounding the facility is used for agriculture. More than 50% of the

surrounding area within a 3-km radius of the site is zoned other than industrial, commercial, or

multi-family residential; therefore, the land-use classification has been defined as Rural in

accordance with EPA1 guidelines.

9. Buildings

Three on-site buildings (designated 66 C, Building 2, and Power Building) have the potential to interact

with exhaust plumes from the generators, and were included in the modeling analysis. No other

buildings were within 145-feet of any proposed generator stack. See Appendix A for the building

locations. Building downwash was included in AERMOD using BPIP-Prime (version 04274).

10. Background Concentration

Background concentrations were obtained using

https://idahodeq.maps.arcgis.com/apps/MapSeries/index.html?appid=0c8a006e11fe4ec5939804b

873098dfe, a collaboration between the Idaho Department of Environmental Quality, Washington

1 40 C.F.R. §51 Appendix W, Section 7.2.3

US Electrodynamics December 2020

State Department of Ecology, and Oregon Department of Environmental Quality. The 1-hr NO2

value is 4.1 ppm and the annual NO2 value is 0.9 ppm.

Per WAC 173-460-150(2)(a), the background concentrations for toxic air pollutants do not need

to be included as this is a first-tier New Source Review.

11. Evaluation of Compliance with Standards

Modeling was performed based on the parameters defined in this report. Table 3 provides the modeled

off-site impacts for 1-hr and annual NO2 in comparison to NAAQS limits. Table 4 provides the modeled

off-site impacts for DEEP and NO2 in comparison to ASILs. The AERMOD output summary is

provided in Appendix B. An electronic copy of the AERMOD files will be provided.
