CUMULATIVE IMPACTS ANALYSIS 

Potential cumulative air quality impacts that might be expected to occur as a result of the 

proposed Project and other reasonably foreseeable projects are both regional and 

localized in nature. These cumulative impacts were evaluated as follows. 

Cumulative impacts from the Project could result from emissions of CO, NOx, SOx, 

VOC and directly emitted PM10 and PM2.5. To assure that the possible existence of other 

projects that might have significant cumulative impacts in conjunction with the Project 

were identified, a search area with a radius of 6 miles1 was used for the cumulative 

impacts analysis. 

Within this search area, three categories of possible projects with combustion sources 

were used as criteria for identification: 

• Projects that are existing and have been in operation since at least early 2006. 

• Projects for which air pollution permits to construct have been issued and that began 

operation after 2006. 

• Projects for which air pollution permits to construct have not been issued, but that are 

reasonably foreseeable. 

Projects that are existing and have been in operation since at least early 2006 are reflected 

in the 2004-2006 ambient air quality data that have been used to represent background 

concentrations; consequently, no further analysis of the emissions from this category of 

facilities was needed. The air quality impact analysis in Section 6.2 added the modeled 

impacts of the proposed project to the maximum background air quality levels measured 

during 2004-2006, thus assuring that these existing projects were taken into account. 

Identification of projects for which air pollution permits to construct would have been 

issued but that would not have been operational by the end of 2006 were requested from 

the SJVAPCD in the July 19, 2007 letter2 included in this appendix. Projects for which 

the emissions change was smaller than 5 tons per year were assumed to be de minimis, 

and were not included in the request. In response to the July 19, 2007 request, the 

District provided on January 24, 2008 the list of projects in Table 6.2-6.1. The annual 

emissions of these projects are negligible as shown in Table 6.2-6.2, and the VOC 

emissions are not subject to air dispersion impact analysis. Therefore, no further 

cumulative air quality impact analysis is required.

Re: Information Request for a Cumulative Air Quality Impact Analysis 

Avenal Energy Project 

Dear Mr. Marjollet: 

Thank you for calling back this morning. Based on our discussion, this letter updates the previous request 

sent to Dave Warner on August 9, 2006. Sierra Research is conducting the air quality and public health 

impact analysis for the Avenal Energy Project. Federal Power Avenal, LLC plans to file an updated 

Application for Certification with the California Energy Commission (CEC) for a combined-cycle gas 

turbine power plant near Avenal, California. The UTM coordinates of the site are 3997.742 km northing, 

764.616 km easting (Zone 10). 

As part of the project review, the CEC requires us to update the analysis of the project’s potential 

cumulative impacts. This is defined by the CEC as “a cumulative air quality modeling impacts analysis of 

the project’s typical operating mode in combination with other stationary source emissions sources within a 

six-mile radius which have received construction permits but are not yet operating, or are in the permitting 

process.” [emphasis added] For each criteria pollutant the CEC staff considers facilities having an 

emission increase of less than five tons per year to be de minimis, so such facilities may be excluded. 

We would like to get from the District a list of projects that meet these criteria, along with sufficient 

emissions information and stack parameters so that we can include these sources in our air dispersion 

modeling. 

Thank you very much for your assistance. If you have any questions regarding the information we are 

requesting, feel free to call. 

Sincerely, 

Eric Walther

AERMAP is the digital terrain pre-processor for the AERMOD model. It analyzes and prepares digital 

terrain data for use within an air dispersion modeling project. AERMAP requires that the digital terrain 

data files be in native (non SDTS) USGS 1-degree or 7.5-minute DEM format. 

5.4 Land Use Characterization 

Land use plays an important role in air dispersion modeling from meteorological data processing to 

defining modeling characteristics such as urban or rural conditions. Land use data can be obtained 

from digital and paper land-use maps. 

These maps will provide an indication into the dominant land use types within an area of study, such 

as industrial, agricultural, forested and others. This information can then be used to determine 

dominant dispersion conditions and estimate values for parameters such as surface roughness, 

albedo, and Bowen ratio. 

• Surface Roughness Length [m]: The surface roughness length, also referred to surface 

roughness height, is a measure of the height of obstacles to the wind flow. Surface 

roughness affects the height above local ground level that a particle moves from the 

ambient airflow above the ground into a “captured” deposition region near the ground. This 

height is not equal to the physical dimensions of the obstacles, but is generally proportional 

to them. Table 5.1 lists typical values for a range of land-use types as a function of season. 

Figure 5.3 - For many modeling applications, surface roughness can be considered to be on the order of one 

tenth of the height of the roughness elements.

The following method was proposed in the U.S. EPA OSW Human Health Risk Assessment 

Protocol41 to determine the surface roughness length for use with the ISC-PRIME/ISCST3 model at 

the application site: 

1. Draw a radius of 3 Km from the center of the stack(s) on the site map. 

2. Classify the areas within the radius according to the land use type categories listed in Table 

5.1 (e.g., water surface, deciduous forest, etc.).

Hazardous Waste Combustion Facilities. EPA530-D-98-001A. U. S. Environmental Protection Agency, Research Triangle 

Park, NC.

 08/06 Rev 1.2 

3. Calculate the wind rose directions from the 5 years of meteorological data to be used for the 

risk analysis. 

4. Divide the area into 16 sectors of 22.5 degrees, corresponding to the wind rose directions. 

5. Identify a representative surface roughness length for each sector, based on an areaweighted average of the land use within the sector. 

6. Calculate the site surface roughness by computing an average surface roughness length 

weighted with the frequency of wind direction occurrence for each sector. 

AERMOD allows wind direction dependent surface characteristics to be used in the processing of the 

meteorological data. The AERMET procedure also uses the area-weighted average of the land use 

with 3 km of the site. The selection of wind direction dependent sectors is described in sections 5.4.1 

to 5.4.3. 

Alternative methods of determining surface roughness height may be proposed. The District should 

review any proposed values prior to use.

• Noon-Time Albedo: Noon-time albedo is the fraction of the incoming solar radiation that is 

reflected from the ground when the sun is directly overhead. Table 5.2 lists typical albedo 

values as a function of several land use types and season. For practical purposes, the 

selection of a single value for noon-time albedo to process a complete year of 

meteorological data is desirable. If other conditions are used, the District should review the 

proposed noon-time albedo values used to pre-process the meteorological data.

• Bowen Ratio: The Bowen ratio is a measure of the amount of moisture at the surface. The 

presence of moisture at the earth’s surface alters the energy balance, which in turn alters 

the sensible heat flux and Monin-Obukhov length. Table 5.3 lists Bowen ratio values as a 

function of land-use types, seasons and moisture conditions. Bowen ratio values vary 

depending on the surface wetness. Average moisture conditions would be the usual choice 

for selecting the Bowen ratio. If other conditions are used the District should review the 

proposed Bowen ratio values used to pre-process the meteorological data.

5.4.1 Wind Direction Dependent Land Use 

AERMET also provides the ability to specify land characteristics for up to 12 different contiguous, 

non-overlapping wind direction sectors that define unique upwind surface characteristics. The 

following properties of wind sectors must be true: 

• The sectors are defined clockwise as the direction from which the wind is blowing, with 

north at 360°. 

• The sectors must cover the full circle so that the end value of one sector matches the 

beginning of the next sector. 

• The beginning direction is considered part of the sector, while the ending direction is not. 
41 of 101 

 08/06 Rev 1.2 

Each wind sector can have a unique albedo, Bowen ratio, and surface roughness. Furthermore, these 

surface characteristics can be specified annually, seasonally, or monthly to better reflect site 

conditions. 

5.4.2 Mixed Land Use Types 

Study areas may contain several different regions with varying land use. This can be handled by 

AERMET through the use of wind sector specific characterization, as described in the previous 

section. 

For models such as ISCST3/ISC-PRIME that do not take advantage of sector-specific 

characterization, the most representative conditions should be applied when land use characteristics 

are required. 

The approach taken by the District is to take a weighted average over a radius of 3 km from the 

facility in all directions. 

This is performed by assessing the land use across the facility study area and applying the 

appropriate values to the land characteristic parameters. A weighted average is then computed based 

on the area of each land use category. 

5.4.3 Seasonal Land Use Characterization 

Land use characteristics can be susceptible to seasonal variation. For example, winter conditions can 

bring increased albedo values due to snow accumulation. 

AERMET allows for season-specific values for surface roughness, albedo, and Bowen ratio to be 

defined. Other models, such as ISCST3/ISC-PRIME, do not support multiple season surface 

characteristics to be defined. In such a case, the most representative conditions should be applied 

when land use characteristics are required. 

5.4.4 Standard and Non-Default Surface Characteristics 

The generation of local meteorological data files can incorporate site-specific surface characteristics. 

It should be noted that any local meteorological files generated for air dispersion modeling should 

provide a clear reasoning for the values used to describe surface characteristics. The District should 

review any proposed surface characteristics prior to submission of a modeling report. 

5.4.5 Defining Urban and Rural Conditions 

The classification of a site as urban or rural can be based on the Auer method specified in the EPA 

document Guideline on Air Quality Models (40 CFR Part 51, Appendix W)45. From the Auer’s method, 

areas typically defined as Rural include: 

• Residences with grass lawns and trees 

• Large estates

U. S. Environmental Protection Agency, Research Triangle Park, NC. 
42 of 101 

 08/06 Rev 1.2 

• Metropolitan parks and golf courses 

• Agricultural areas 

• Undeveloped land 

• Water surfaces 

Auer defines an area as Urban if it has less than 35% vegetation coverage or the area falls into one 

of the following use types: 

Urban Land use 

Type Use and Structures Vegetation 

I1 Heavy industrial Less than 5% 

I2 Light/moderate industrial Less than 5% 

C1 Commercial Less than 15% 

R2 Dense single / multi-family Less than 30% 

R3 Multi-family, two-story Less than 35% 

Follow the Auer’s method, explained below, for the selection of either urban or rural dispersion 

coefficients: 

Step 1: Draw a circle with a radius of 3 km from the center of the stack or centroid of the 

polygon formed by the facility stacks. 

Step 2: If land use types I1, I2, C1, R2, and R3 account for 50 % or more of the area within the 

circle, then the area is classified as Urban, otherwise the area is classified as Rural. 

To verify if the area within the 3 km radius is predominantly rural or urban, overlay a grid on top 

of the circle and identify each square as primarily urban or rural. If more than 50 % of the total 

number of squares is urban than the area is classified as urban; otherwise the area is 

rural.(35) 

An alternative approach to Urban/Rural classification is the Population Density Procedure: Compute 

the average population density, p, per square kilometer with Ao as defined above, 

(a) If p > 750 people/km2

, select the Urban option, 

(b) If p <= 750 people/km2, select the Rural option. 

Of the two methods above, the land use procedure is considered a more definitive criterion. The 

population density procedure should be used with caution and should not be applied to highly 

industrialized areas where the population density may be low and thus a rural classification would be 
43 of 101 

 08/06 Rev 1.2 

indicated, but the area is sufficiently built-up so that the urban land use criteria would be satisfied. In 

this case, the classification should already be Urban and urban dispersion parameters should be 

used. 

6. METEOROLOGICAL DATA 

6.1 Comparison of Screening and Refined Model Requirements 

Meteorological data is essential for air dispersion model modeling as it describes the primary 

environment through which the pollutants being studied migrate. Similar to other data requirements, 

screening model requirements are less demanding than refined models. 

SCREEN3 provides 3 methods of defining meteorological conditions: 

• Full Meteorology: SCREEN will examine all six stability classes (five for urban sources) and 

their associated wind speeds. SCREEN examines a range of stability classes and wind 

speeds to identify the "worst case" meteorological conditions, i.e., the combination of wind 

speed and stability that results in the maximum ground level concentrations. 

• Single Stability Class: The modeler can select the stability class to be used (A through F). 

SCREEN will then examine a range of wind speeds for that stability class only. 

• Single Stability Class and Wind Speed: The modeler can select the stability class and input 

the 10-meter wind speed to be used. SCREEN will examine only that particular stability 

class and wind speed. 

6.2 Preparing Meteorological Data for Refined Modeling 

AERMOD and ISC models require actual hourly meteorological conditions as inputs. The refined 

models require pre-processed meteorological data that contains information on surface 

characteristics and upper air definition. This data is typically provided in a raw or partially processed 

format that requires processing through a meteorological pre-processor. The ISC models make use of 

a pre-processor called PCRAMMET, while AERMOD uses a pre-processor known as AERMET 

described further in the following sections. 

6.2.1 Hourly Surface Data 

Hourly surface data is supported in several formats including: 

1. CD-144 – NCDC Surface Data: This file is composed of one record per hour, with all 

weather elements reported in an 80-column card image. Table 6.1 lists the data contained in 

the CD-144 file format that is needed to pre-process your meteorological data.

2. MET-144 – SCRAM Surface Data: The SCRAM surface data format is a reduced version of 

the CD-144 data with fewer weather variables (28-character record). Table 6.2 lists the data 

contained in the SCRAM file format.

Dry Bulb Temperature (° Fahrenheit) 22-24 

Total Cloud Cover (Tens of Percent) 25-26

The SCRAM data does not contain the following weather variables, which are necessary for 

dry and wet particle deposition analysis: 

1. Surface pressure: for dry and wet particle deposition; 

2. Precipitation type: for wet particle deposition only; or 

3. Precipitation amount: for wet particle deposition only. 

3. SAMSON Surface Data: The SAMSON data contains all of the required meteorological 

variables for concentration, dry and wet particle deposition, and wet vapor deposition. 

If the processing of raw data is necessary, the surface data must be in one of the above 

formats in order to successfully pre-process the data using PCRAMMET or AERMET. 

6.2.2 Mixing Height and Upper Air Data 

Upper air data, also known as mixing height data, are required for pre-processing meteorological data 

required to run the ISC-PRIME models. It is recommended that only years with complete mixing 

height data be used. In some instances, mixing height data may need to be obtained from more than 

one station to complete multiple years of data. 

Mixing height data are available from: 

1. SCRAM BBS –download free of charge, mixing height data for the U.S. for years 1984 

through 1991.

 08/06 Rev 1.2 

2. WebMET.com –download free of charge, mixing height and upper air data from across 

North America, including Ontario.

Month 8-9 

Day 10-11 

AM Mixing Value 14-17 

PM Mixing Value (NCDC) 25-28 

PM Mixing Value (SCRAM) 32-35 

AERMOD requires the full upper air sounding, unlike ISCST3/ISC-PRIME, which only require the 

mixing heights. The upper air soundings must be in the NCDC TD-6201 file format or one of the FSL 

formats. 

6.2.3 AERMET and the AERMOD Model 

The AERMET program is a meteorological preprocessor that prepares hourly surface data and upper 

air data for use in the U.S. EPA air quality dispersion model AERMOD. AERMET was designed to 

allow for future enhancements to process other types of data and to compute boundary layer 

parameters with different algorithms. 

AERMET processes meteorological data in three stages: 

1. The first stage (Stage1) extracts meteorological data from archive data files and processes 

the data through various quality assessment checks. 

2. The second stage (Stage2) merges all data available for 24-hour periods (surface data, 

upper air data, and on-site data) and stores these data together in a single file. 

3. The third stage (Stage3) reads the merged meteorological data and estimates the 

necessary boundary layer parameters for use by AERMOD. 

Out of this process two files are written for AERMOD: 

1. A Surface File of hourly boundary layer parameters estimates; 

2. A Profile File of multiple-level observations of wind speed, wind direction, temperature, and 

standard deviation of the fluctuating wind components. 

6.2.4 PCRAMMET and the ISC Models 
46 of 101 

 08/06 Rev 1.2 

The PCRAMMET program is a meteorological preprocessor, which prepares NWS data for use in the 

various U.S. EPA air quality dispersion models such as ISCST3/ISC-PRIME. 

PCRAMMET is also used to prepare meteorological data for use by the CAL3QHCR model, and for 

use by the CALPUFF puff dispersion model when used in screening mode. 

The operations performed by PCRAMMET include: 

• Calculating hourly values for atmospheric stability from meteorological surface observations; 

• Interpolating the twice daily mixing heights to hourly values; 

• Optionally, calculating the parameters for dry and wet deposition processes; 

• Outputting data in the standard (PCRAMMET unformatted) or ASCII format required by 

regulatory air quality dispersion models. 

The input data requirements for PCRAMMET depend on the dispersion model and the model options 

for which the data is being prepared. The minimum input data requirements for PCRAMMET are: 

• The twice-daily mixing heights, 

• The hourly surface observations of: wind speed, wind direction, dry bulb temperature, 

opaque cloud cover, and ceiling height. 

For dry deposition estimates, station pressure measurements are required. For wet deposition 

estimates, precipitation type and precipitation amount measurements for those periods where 

precipitation was observed are required. 

The surface and upper air stations should be selected to ensure they are meteorologically 

representative of the general area being modeled. 

6.3 Regional Meteorological Data 

The District has prepared regional meteorological data sets for use in Tier 2 modeling in several 

formats: 

• Regional pre-processed model ready data for AERMOD, with land characteristics for 

CROP, RURAL and URBAN conditions. 

• Regional Merge files enabling customized surface characteristics to be specified and 

processed through AERMET Stage3. 

• Hourly surface data and upper air data files allowing for complete processing through 

AERMET. 

The above data sets are available online and provide a unique, easily accessible resource for air 

dispersion modelers in the San Joaquin Valley. The availability of standard meteorological data will 

reduce inconsistencies in data quality and requests to the regulatory agency on obtaining data. 

The surface meteorological sites used were Bakersfield, Fresno, Hanford, Madera, Modesto, and 

Stockton. The following meteorological elements were used in AERMET processing for the 5 year 
47 of 101 

 08/06 Rev 1.2 

period from 2000 to 2004: ceiling height, wind speed, wind direction, air temperature, total cloud 

opacity and total cloud amount. 

The upper air station used was Oakland, CA. Table 6.4 gives the locations of the surface 

meteorological sites and lists the upper air station used for each site. The locations of the upper air 

sites are given in Table 6.5.

6.3.1 Pre-Processing Steps 

The regional data for AERMOD is provided in 2 forms: 

• Merged: Data has been processed through Stage2 of AERMET (AERMET stages are 

described in Section 6.2.3) to produce a “Merge” file. This file can then be processed through 

AERMET Stage3 with custom surface condition data to produce a meteorological data set 

specific to the site for use with AERMOD (Tier 3). 

• Regional: Data has been processed through Stage3 of AERMET with predefined Land Use 

characteristics for “Urban”, “Rural”, and Crop” environments. The data is ready for use with 

AERMOD (Tier 2). 

6.3.1.1 Regional Meteorological Data Processing Background 

Regional meteorological datasets are generated in AERMET, Stage3 processing step, using different 

wind independent surface conditions. It is assumed that surface conditions are the weighted average 

over a radius of 3 km from the meteorological station split into 8 sectors. See Appendix E for a 

detailed description of each of the dataset processed. The surface conditions needed are the albedo 

(A), the Bowen ratio (Bo) and the surface roughness (Zo). These parameter values are found in 

Appendix E and were derived from data in Tables 4.1, 4.2b (albedo for average conditions) and 4.3 of 

the AERMET User’s Guide46.

1.0 INTRODUCTION

Delta was contracted by the Palomar Energy Center to conduct emissions testing

during a "Cold Start Up" of the CT-2 gas turbine power generating unit stack. Delta

conducted the testing to comply with the requirements given by the San Diego Air

Pollution Control District (SDAPCD) in a letter from Suzanne Blackburn to Kelly Hunt

dated September 14, 2007.

The test program included exhaust measurements of:

• Oxygen (02)

• Carbon Monoxide (CO)

• Nitrogen Oxide (NO)

• Nitrogen Dioxide (N02)

• Volatile Organic Compounds (VOC -eXcluding methane and ethane)

• Particulate Matter (PM)

• Formaldehyde, Acetaldehyde, and Acrolein (aldehydes)

• Benzene, Toluene, Xylenes (BTX) and Acrolein

• Polycyclic Aromatic Hydrocarbons (PAH)

This report presents the results of the testing along with a description of the unit,

test procedures, sample locations, and quality assurance information.

The tests were conducted on October 22, 2007. Bob Finken led the Delta test

team consisting of Arlene Bell, Gary Bridge, Robert Leyva, and Ray Madrigal. Larry

Owusu of SDAPCD was on site to witness the tests.

Testing was originally planned such that one complete set of tests would be

executed during the 1st hour of the start up, and another set of tests performed during the

balance of the start up period. Only the 1

st set of tests was performed due to

complications arising from wildfires in the vicinity on the day of the test. The proximity of

the fires to the test site dictated aborting the program in favor of safety and data quality.

Ammonia sampling was planned but not conducted since the testing ceased

before ammonia injection began.

2.0 UNIT DESCRIPTIONS

The facility is owned and operated by San Diego Gas & Electric. The combined

cycle facility is comprised of two General Electric Frame 7FA gas turbines, each with a

nominal rating of 165 MW. Each of the combustion turbine generators (CTG's) is

equipped with Dry Low NOx (DLN) burner systems, a heat recovery steam generator

(HRSG), auxiliary duct burners, an oxidation catalyst, and a selective catalytic reduction

unit to control atmospheric emissions. The Palomar Energy Center fires pipeline quality

natural gas exclusively. Exhaust gases from the CTGfHRSG systems are vented to the

atmosphere via dedicated exhaust stacks.

The units are equipped with Continuous Emissions Monitoring Systems (CEMS)

that provides measurements of O2, NOx and CO concentrations. The systems are

extractive type with a heated line extending from the probes to the sample conditioning

unit. The CEMS is a packaged system provided by ESC (Environmental Systems

Corporation).

The applicable emission limits are shown in Table 2-1 below.

3.0 TEST DESCRIPTION

3.1 TEST CONDITIONS

The tests were performed during a "Cold Start Up". The facility permit defines a

cold start up as a start up of one of the units after a period of at least 72 hours of nonoperation. The permit also defines this period as being less than 6 hours in duration,

and/or the turbine reaching 40% of full load.

During each test, the selected process parameters shown below in Table 3-1 were

recorded.

All tests were conducted at the sample locations on the exhaust stack of the

combustion turbines. Each unit has a dedicated exhaust stack through which products of

combustion exit to the atmosphere. The exhaust stacks are 204" 1.0. with a platform for

sampling. There are four, six-inch pipe size sample ports accessible from this platform.

The sample ports are located at 90° intervals on one plane. The sample locations meet

the minimum requirements of EPA Method 1, being more than 2 diameters downstream

and % diameter upstream of the nearest flow disturbances.

The testing for all species was performed using single point sampling, with the

probes located at or near the center of the stack. This approach is adopted since the

test conditions are transient, and it would not be possible to distinguish between temporal

and spatial variations if the probe positions were changing at the same time as the unit

load was changing.

3.3.1 Emissions Test Procedures

Descriptions of the test procedures are included the following sections.

3.3.1.1 Continuous Gaseous Measurements.

NOx, O2, and CO were measured according to SOAPCD reference methods using

Delta's continuous emissions monitoring system (CEMS). The sampling system employs

a heated line and moisture removal trap to conserve any NOz that might be present in the

flue gas. The "High NOz" procedure was performed using a NOx analyzer with separate

outputs for total NOx and NO only. The post test calibrations were not performed in light

of the suspension of testing.

Delta utilizes a mobile emission measurement laboratory for the performance of

O2, CO, and NOx measurements. The laboratory is housed in a vehicle outfitted to

provide a clean, quiet, environmentally controlled base for the testing operations. The

laboratory has lighting, electrical distribution, air conditioning and heating to support the

test instruments and provide for optimal test performance.

Oz, CO, and NOx concentrations are measured using an extractive sampling

system consisting of a heated probe, a heat traced Teflon sample line connected to a

thermos-electrically cooled sample dryer. Following the dryer, the sample is drawn into a

R026220 5
Teflon lined pump where it is pressurized and then filtered for delivery to the gas analysis

portion of the system.

NOx concentration is determined using a chemiluminescence analyzer. The

analyzer is equipped with a low temperature N02 - NO converter for the determination of

total nitrogen oxides without interference from other nitrogen containing compounds.

Oxygen concentration is determined using an electro-chemical cell analyzer. The

analyzer has three full scale ranges; 0-5%, 10%, and 25%. The cell contains an

electrolytic fluid that reacts with oxygen to generate an electrical signal proportional to

the concentration.

CO is measured using a non-dispersive infrared analyzer manufactured by API or

Thermo Environmental. The analyzers have full scale ranges of 0 to 0-1000 ppm.

The sampling system is comprised of a stainless steel probe, heated teflon

sample line, two-pass thermo-electrically cooled water removal system, teflon lined

sample pump and teflon sample line connected to the analyzer gas selection manifold.

The analyzers and sampling system are subjected to a variety of calibration and

quality assurance procedures induding leak checks, linearity and calibration error

determinations before sampling, and system bias and drift determinations as part of each

test run. Data are corrected for any observed bias or drift in accordance with the

reference methods.

All calibrations are documented on the strip chart recorder. The appropriate

values are marked and the type of calibration performed is written on the chart.

Figure 3-1 presents a flow chart for the SDAPCD Method 100 calibration

sequence. All calibrations are documented on the strip chart recorder by the appropriate

values are marked and the type of calibration performed is written on the chart.

Following assembly of the system, analyzer warm up time, and a successful leak

check of the sample system, the calibration/test sequence presented in Figure 1 can

begin.

An Analyzer Calibration is performed as necessary by adjusting the zero and

span settings of the analyzer. These calibrations are not necessarily recorded on the

chart recorder. Calibration Error is then determined at three levels for each range (which

is expected to be used) of each analyzer. This check is performed, at a minimum, once

at the beginning and once at the end of each test day. The calibration error must not

exceed ±2% of the full range of the analyzer as determined by the following equation:

C I

"b t" E Analyzer Response - Cal. Gas Value * 1000/ a I ra Ion rror = /0

Analyzer Range

The data from the Calibration Error test can be used to determine Analyzer

Linearity. The analyzer response to the mid gas is predicted using linear regression and

the analyzer response to the zero and high calibration gas and the zero and high

R026220 6
calibration gas values. The analyzer linearity must be demonstrated on a semi-annual

basis using the following equation:

AnalyzerLinearity AnalyzerResponse-PredictedResponse *1 00%

Full Scale

where:

Responseto High Gas -Responseto ZeroGas

PredictedResponse * MidGasValue +Responseto ZeroGas

HighGasValue

A N02 to NO converter efficiency test is conducted at the beginning of each test

day. Greater than 90% efficiency must be demonstrated for testing to proceed.

The Sample System Bias test is performed before and after each test run and

must not exceed ±5% (15% for N02) of the gas value and 2% of the upscale span gas.

The system bias is calculated using the following equation:

S I S t B' 100 (Bias -Bias Zero) * 1000/ ampe ys em las= - /0

(Direct - DirectZero)

where:

Response to Analyzer Cal = The analyzer response to the last time the same

calibration gas was introduced directly to the analyzer (this may be the pre-test

calibration error value or a more recent analyzer calibration adjustment)

Analyzer response time is also determined as part of the initial system bias

checks for each test series.

Zero and Calibration Drift are calculated for each test run based on the analyzer

response during the pre- and post-test sample system bias test. Zero and upscale drift

must not exceed ±2% of the analyzer range.

Post- Test System Bias Resonse - Pre - Test System Bias Response Analyzer Drift = * 100%

Analyzer Range

The pre- and post-test analyzer response during the sample system bias test are

used to correct the raw test average for any sample system bias and analyzer drift. The

drift/bias corrected data are the actual reported concentrations and are used for

subsequent calculations (~ass emission rates, Ib/MMBtu, corrections to 3% or 15% O2,

etc.). The drift/bias corrections are performed using the following equation:

where:

Cc = Drift/bias corrected concentration

C = Raw Test Average

Cm = Average of pre- and post-test response to sample system bias span

Co =Average of pre- and post-test to sample system bias zero

Cma = Span gas value

R026220 7
For NOx effluent gas concentrations, where the stack effluent contains more than

5 percent of the total NOx as N02, calculate the CO, O2 and CO2 emissions as specified

in section 7.2.2.1. Correct the averaged NOx and NO emission values, for each subtest,

for NOx analyzer drift and calibration error using the following:

To calculate the total NOx gas concentration in the stack effluent use the following

equation:

NOx gas =NO gas + N02 gas

SOAPeD Method 100 specifies allowed analyzer interferences of 2% for each

analyzer type. The analyzers used by Delta are certified by the manufacturers to have

interference responses which meet the requirements of Method 100.

The method for determining the efficiency of the N02 to NO converter involves

the use of a cylinder containing a certified concentration of N02• This test is performed

once per test day.

3.3.1.2 Volatile Organic Compounds

Volatile Organic Compounds were determined using a combination of EPA

method 25A and modified and simplified EPA method 18.

The EPA Method 25A sampling was continuous during the entire cold start up

period, except for period of calibration or range changing, Delta expects VOC's to be in

excess of 1000 ppmv for a short duration during Start up. Delta used a 3000 ppmv scale

to characterize VOC emissions during these operating conditions. If VOC concentrations

are lower than expected, this scale may be reduced. VOC concentration was measured

over the permit limit duration.

• Method 18 was employed to determine the methane and ethane

concentrations to allow the determination of non-methane/ethane volatile

organic compounds.

Notes specific to this program are provided below for clarification.

• Samples for methane and ethane were collected from the SOAPCO

Method 100 sample system

• The pre-survey was not performed

• The samples were not heated after collection as only volatile species are

of interest

• A single sample was collected each hour during the startup

• The samples were analyzed for methane and ethane by gas

chromatography/FlO

The methane and ethane results were subtracted from the Total Hydrocarbon

results obtained from the EPA Method 25A results for the corresponding time period.

3.3.1.3 PM by CARB Method 5

The test method requires isokinetically Withdrawing exhaust gas through a

sampling train that collects particulate on a nozzle, probe, filter and filter glassware, and

impingers. The sampling train used for this program consists of:

1. Stainless steel nozzle and glass lined probe heated to 250°F with an S-type pitot

tube for velocity measurements.

2. 83 mm 934-AH fiberglass filter heated in an oven box to 250°F.

3. An impinger train connected to the back of the filter holder by a Teflon connecting

line. The impinger train consists of two impingers containing 100ml each of 01

water, followed by an empty impinger and an impinger containing silica gel.

R026220 11
The impingers are weighed before sampling and all components such as the

probe nozzle and filter are visually inspected before sampling.

After sampling the following procedures were used to recover the samples:

1. Nozzle and probes, visually inspected for nicks or breakage, then sealed. Rinse

and brush nozzle and probe 3 times with acetone into an amber glass bottle.

2. The filter is returned to its pre-numbered petri dish.

3. The front half of the filter holder is also rinsed and brushed with' acetone and the

rinse combined with step #1 above.

4. The Teflon connecting line is drained into the first impinger.

5. The impingers are weighed for moisture determination.

6. The impinger liquid is quantitatively recovered into Nalgene bottles

Particulate mass is determined gravimetrically using CARB Method 5 analytical

procedures. Sample analysis of the acetone rinses and filter consists of evaporating the

acetone at room temperature, followed by desiccating and weighing the sample. The

sample analysis of the impinger catch consists of evaporating the water at 105°C

followed by desiccating and weighing the sample. Acetone and 01 water blanks were

collected during sampling and analyzed with the samples.

The particulate samples were analyzed in Delta's in-house laboratory. The filters

and beakers were tared on the same analytical balance before the program. Delta's

laboratory uses all required EPA procedures including balance calibration and

temperature and humidity control.

3.3.1.4 Formaldehyde, Acetaldehyde, and Acrolein (aldehydes) by Modified

CARB Method 430

Samples for formaldehyde, acetaldehyde and acrolein were collected hourly

during the cold start-up.

The method was modified to obtain more accurate results for acrolein by adding

toluene to the ONPH solution. This allows immediate extraction of the acrolein derivative

into the toluene and minimizes contact with the acidic media that can produce low results

for acrolein.

In this method, the exhaust gas is drawn non-isokinetically through a heated glass

probe and Teflon line into a series of acidified DNPH filled midget impingers. A low-level

dry gas meter fitted with a calibrated orifice that restricts the flow rate to 0.5 I/min was

used to measure the total volume of exhaust gas sampled. The line is rinsed with a

portion of the' first impinger catch. Each vial is analyzed separately for formaldehyde,

acetaldehyde and acrolein by HPLC.

R026220 12
The following QAlQC procedures were conducted per test condition:

• Screening of ONPH reagent to meet 2 day holdline;

• Field blanks in conjunction with each sample;

• One field spike;

• One trip blank;

• One trip spike

• Laboratory blanks;

• Laboratory matrix spike

3.3.1.5 Benzene, Toluene, Xylenes (BTX) and Acrolein by Modified CARB

Method 410A and TO-15

Benzene, toluene, xylene and acrolein were collected hourly in Summa polished

canisters and analyzed by GC/MS.

The Summa canisters were used so that additional data can be obtained during

the test program.

3.3.1.6 Polycyclic Aromatic Hydrocarbons (PAH)

A single sample for polycyclic aromatic hydrocarbons (PAH) was collected using

CARB Method 429. A single integrated sample was collected over the entire duration of

the cold start-up.

In this procedure, the flue gas is withdrawn isokinetically and passed through a

heated glass probe and Method 5 type Teflon coated filter to a Teflon line and an XAO-2

resin column. The resin column is connected to a series of impingers containing 100 ml

each of sodium carbonate/sodium bicarbonate in the first two impingers, followed by an

empty impinger and an impinger containing silica gel. The Teflon coated filter and

NazCO:/NazHC03 solution prevents degradation of the PAH species by eliminating

potential contact with acidic or basic sampling media.

This method is approved for quantitation of the following PAH species.

All sampling media are pre-cleaned to eliminate PAH contamination and other

organic species. The filters are extracted with methylene chloride and stored in petri

dishes lined with hexane rinsed aluminum foil and the XAD-2 resin is extracted until

clean. Pre-test analysis for both the XAD-2 resin lot and filter extract is required. The

sampling train components (including the probe, glassware and connecting lines) are

pre-cleaned using high purity water, acetone, hexane and methylene chloride.

Field spikes are added to each XAD-2 resin module. A field blank is collected

during each sampling program.

PAH Samples are recovered with high purity GC/MS grade acetone, hexane, and

methylene chloride into amber glass bottles cleaned to EPA specifications for organics.

Samples are kept at <4°C until extraction and analysis.

Samples are analyzed by HRGC/HRMS to obtain detection limits of 10-25 ng per

sample per species. Sample analysis also includes analysis of a method blank, blank

matrix spikes and spiking of the samples with deuterated PAH species to evaluate the

extraction and analysis procedures.

3.3.1.7 Stack Flow Rate

Exhaust flow rate from the certified CEMS was applied to develop emission rates.

3.4 TEST SCHEDULE

The test program was conducted on October 22, 2007.

Testing was originally planned such that one complete set of tests would be

executed during the 1st hour of the start up, and another set of tests performed during the

balance of the start up period. Only the 1

st set of tests was performed due to

complications arising from wildfires in the vicinity on the day of the test. The proximity of

the fires to the test site dictated aborting the program in favor of safety and data quality.

Appendix A.2 Quality Assurance Program Summary

R026220 A-3
QUALITY ASSURANCE PROGRAM SUMMARY

Delta Air Quality Services, Inc. is committed to providing emission related data

which is complete, precise, accurate, representative, and comparable. Delta's quality

assurance program and procedures are designed to ensure that the data meet or exceed

the requirements of each test method for each of these items. The quality assurance

program consists of the following items:

• Assignment of an Internal QA Officer

• Development and use of an internal QA Manual

• Personnel training

• Equipment maintenance and calibration

• Knowledge of current test methods

• Chain-of-custody

• QA reviews of test programs

Assignment of an Internal QA Officer: Delta has assigned an internal QA Officer who is

responsible for administering all aspects of the QA program.

Internal Quality Assurance Manual: Delta has prepared a QA Manual according to the

guidelines issued by EPA. The manual documents and formalizes all of Delta's QA

efforts. The manual is a "living" document which is revised as Delta adds capabilities and

procedures. The QA manual provides details on the items provided in this summary.

Personnel Training: Personnel training is essential to the production of high quality test

results. Delta's training programs include:

• A requirement for all technical personnel to read and understand the test

methods performed

• Arequirement for all technical personnel to read and understand the Delta QA

manual

• In-house training

• Quality Assurance meetings

• Attendance at EPA sponsored training courses

• Maintenance of training records.

Equipment Maintenance and Calibration: All laboratory and field equipment used as a

part of Delta's emission measurement programs is maintained according to

manufacturer's recommendations. A summary of the major equipment maintenance

schedules is summarized in Table A-1. In addition to routine maintenance, calibrations

are performed on all sampling equipment according to the procedures outlined in the

applicable test method. The calibration intervals and techniques for major equipment

components is summarized in Table A-2.

Knowledge of Current Test Methods: Delta maintains current copies of EPA, ARB, and

SCAQMD Source Test Manuals and Rules and Regulations. Delta personnel coordinate,

attend, and present papers at emission testing related conferences. Delta personnel

maintain memberships in the Air and Waste Management Association and Source

Evaluation Society. Delta personnel continually work with industry and regulatory

agencies in monitoring and developing new methods and rules.

R026220 A-4
Chain-of-Custody: Delta maintains chain-of-custody documentation on all data sheets

and samples. Samples are stored in a locked area accessible only to Delta source test

personnel. Data sheets are kept in the custody of the originator, program manager, or in

locked storage until return to Delta's office. Upon return to the office, copies are made

and stored in a locking file. The original data sheets are used for report preparation and

any additions are initialed and dated.

QA Reviews: Every Delta report is reviewed by someone separate from the report

author. The reviewer is selected based on knowledge of the test methods used and the

source tested. Periodic field, laboratory, and report reviews are performed by the QA

Officer. Test plans are reviewed to ensure proper test methods are selected and reports

are reviewed to ensure that the methods was followed and any deviations from the

methods are justified and documented.

Subject: NO2/NOx Ratios for Modeling

Ralph,

Here is the NO2/NOx information I have for Palomar startups (see attached). We have data recorded from the facility's 

CEMS for four hot/warm (after overnight shutdown) startups in May and some District source test data for NO2 (actually 

NO) for one cold startup in July of this year. Based on the CEMS data, for the warm starts in May the highest average 1-

hour value for the NO2/NOx ratio was about 35% in the exhaust stack. SDG&E also had their source test van measure 

NOx during two of the startups and got slightly smaller values, about 30%. The highest 1-hour average NO2/NOx ratio at 

the inlet to the SCR during the startups was consistently over 75% with the highest value being 87%. This is the only 

information I have for the uncontrolled NO2/NOx ratio.

Interestingly, the 1-hour average SCR inlet NO2/NOx ratio (but not total NOx) was much higher than the stack NO2/NOx 

ratio even when there was no ammonia flow to the SCR. This could be do to catalytic reduction of NO2 to NO (by CO, for 

example, which is also much higher during startups) in the SCR or downstream heat exchange components. However, it 

also is possible that the SCR inlet probe location (6' from the bottom of the 60' foot high HRSG duct) might result in 

measurements that are not representative of overall NO2/NOx in the exhaust at the inlet. The only way to rule out 

stratification at the SCR inlet would require additional measurements of NO2 and NOx at additional locations across the 

duct at the SCR inlet, which we currently do not plan to do. There was no significant stratification indicated for the 

exhaust stack NOx measurements during a full load source test. 
2

The data for NO2/NOx data for the July cold startup is much more limited. The District did not record NO2 (or NO) data 

from the facility's CEM, and the District NOx source test instrumentation, at the time, could not simultaneously (on a 

minute-by-minute time scale) measure both NOx and NO2. Therefore, there is only NO2 information available for some 

portions of the startup. However, the NO2/NOx ratios appear smaller than in the May hot/warm startups, although we are 

still checking over the data. 

Based on the information available for the Palomar plant, my preliminary recommendation is to use a NO2/NOx ratio of 

40% for startups with SCR in place and a NO2/NOx ratio of 100% for uncontrolled commissioning emissions as 

conservatively high estimates. Based on the most recent District source test for Palomar at full load (attached), my 

preliminary recommendation is to use 25% for the NO2/NOx ratio at full load as a conservatively high estimate.

Thanks.

Steve

1. BACKGROUND 

1.1 Purpose

On behalf of Avenal Power Center, LLC (APC, or Applicant), Sierra Research is 

submitting this modeling protocol to the U.S. Environmental Protection Agency (EPA) 

for the air dispersion modeling conducted for the revised supplemental nitrogen dioxide 

(NO2) air quality impact analysis submitted in support of the Avenal Energy Project 

(Project) Application for a Prevention of Significant Deterioration (PSD) Permit. 

1.2 Project Description

The Avenal Energy Project will be a combined-cycle 600-megawatt (MW) power 

generation facility consisting of two GE Energy Frame 7FA natural gas-fired turbinegenerators, a single condensing steam turbine generator (STG), air-cooled condenser, and 

associated balance-of-plant equipment. The facility includes the following: 

• Two General Electric PG7241 (FA) combustion turbines (or equivalent), rated at 

180 MW (nominal net, at site design conditions); 

• Two heat recovery steam generators (HRSGs) equipped with duct burners; 

• One natural gas-fueled auxiliary boiler; 

• One natural gas-fueled emergency standby generator engine; and 

• One Diesel-fueled emergency standby fire water pump engine. 

The revised supplemental air quality impact analysis addresses proposed facility 

operation in the following modes: 

• Baseload (100%) operation without duct firing; 

• Baseload (100%) operation with duct firing; and 

• Startup/shutdown operations, evaluated as an average 50% load operation without 

duct firing. 

The facility will be located on a portion of a 148-acre site at the eastern edge of the city 

limits of Avenal, Kings County, California, adjacent to the San Luis Canal (see Figure 1).

Agricultural land uses currently occupy and surround the site. The location of the site is 

the following: 

• Latitude: 36.088394° North 

• Longitude: 120.061141° West 

 or, in Universal Transverse Mercator (UTM) coordinates, 

• Northing: 3,997.742 kilometers (km) and 

• Easting: 764.616 kilometers (North American Datum [NAD] 27, Zone 10). 

The nominal site elevation is 340 feet (104 meters) above mean sea level. 

1.3 Permit History

The following are key dates in the project’s permit history: 

• February 15, 2008 − PSD and ATC permit applications submitted to EPA and 

SJVAPCD, respectively; 

• March 19, 2008 – EPA issued letter of completeness on the PSD application; 

• October 30, 2008 − District FDOC issued; and 

• June 16, 2009 − EPA draft PSD permit issued. 

A full ambient air quality impact analysis demonstrating compliance with the 1-hour and 

8-hour CO National Ambient Air Quality Standards (NAAQS), the 24-hour PM2.5

NAAQS, and the annual average NO2 NAAQS was included in the February 2008 PSD 

application. The air dispersion modeling indicated that the project’s impacts would not 

exceed the applicable Significant Impact Levels (SILs) for any of these pollutants or 

averaging periods. EPA confirmed this conclusion in their proposed approval of the PSD 

permit for the Project.a

 At the times that the application was submitted to EPA, accepted 

as complete by EPA, and proposed for approval by EPA, there was no hourly NO2

NAAQS. 

1.4 The New NO2 National Ambient Air Quality Standard

On February 9, 2010, EPA revised the primary NO2 NAAQS, establishing a new onehour NO2 standard to supplement the existing annual standard.b

 The new standard 

became effective on April 12, 2010. It is a statistically based standard at a level of 100

2. METHODOLOGY 

2.1 Overview of Methodology

The revised supplemental NO2 air quality impact analysis considers impacts from project 

emissions, any identified nearby sources which create significant concentration gradients 

in the impact area, and regional background concentrations. The NO2 impacts in the 

study area from project and nearby sources are estimated using AERMOD and the Plume 

Volume Molar Ratio Method (PVMRM) for each hour in a five-year analysis period 

(2005–2009), based on recent, representative NO2 and O3 background air quality data, 

and representative meteorological data, obtained from the District’s website. The 

representative background NO2 concentration for each hour are added to the modeled 

NO2 impact from the Project (plus those from included nearby sources, if any) to 

determine the predicted NO2 concentration for each hour in the analysis period, for each 

receptor. 

EPA has provided guidance2

 on the use of AERMOD modeling results to calculate NO2

design values for comparison to the new standard. This guidance forms the basis for the 

procedure that will be followed, as outlined below. 

• For each day in the study period, the highest one-hour NO2 concentration is 

determined for each receptor in the modeling domain.a

 This is the daily 

maximum NO2 concentration. 

• At each receptor, for each calendar year in the five-year analysis period, the 98th

percentile daily maximum NO2 concentration is determined. Because EPA and 

District guidance are used to develop a complete annual data set (i.e., 365 valid 

days), the 98th percentile corresponds to the 8th highest daily maximum. 

• At each receptor, the 98th percentile daily maximum concentrations are averaged 

across the five-year period of available data. 

 

a

 The February 2010 guidance is designed to determine the project’s design value, which is the 98th

percentile of the project’s impact. When using a screening tool for compliance determination, this design 

value is added to highest background concentration to demonstrate compliance. Because it is a screening 

approach, it is designed to be conservative. The present analysis refines the screening approach by pairing 

the modeled impacts with the corresponding measurements of background concentrations, and applying the 

guidance to the resulting total impact to demonstrate compliance. 

-6- 
• The five-year average 98th percentile concentration across all receptors represents 

the modeled 1-hour NO2 concentration for comparison with the NAAQS. 

• The final concentration is converted from μg/m3

 (the units used by AERMOD) to 

ppb (the units in the standard) using the ratio 100 μg/m3

 = 53 ppb (i.e., 100 ppbv 

= 188.7 μg/m3), following EPA guidance; the result is rounded to the nearest ppb 

and compared to the standard. 

2.2 AERMOD Modeling

The following EPA air dispersion models are used to quantify pollutant impacts on the 

surrounding environment based on the emission sources’ operating parameters and their 

locations: 

• American Meteorological Society/Environmental Protection Agency Regulatory 

Model Improvement Committee (AERMIC) model, also known as AERMOD 

(Version 09292); and 

• Building Profile Input Program – Plume Rise Model Enhancements 

(BPIP-PRIME, Version 04274). 

The original air dispersion modeling for the Project was conducted with AERMOD 

Version 07026, but the May 13, 2010 supplemental air dispersion modeling analysis3

 and 

this revised supplemental analysis use AERMOD Version 09292. Apart from PVMRM, 

standard default AERMOD control parameters are used, including stack tip downwash, 

elevated terrain, and sequential meteorological data check. The modeled hourly NO2

concentrations are limited by the available ozone according to the use of AERMOD with 

the PVMRM option. 

AERMOD without PVMRM is a dispersion model. It predicts ground-level 

concentrations based on the distribution of emissions from the sources being modeled. 

However, the NOx emitted at the stack is primarily a mixture of NO and NO2. If 

conversion of stack NO to NO2 in the atmosphere is not taken into account, the model 

will underpredict NO2 impacts. At the same time, if the unrealistic assumption is made 

that 100% of stack NO is converted to ground-level NO2 at all receptors—regardless of 

transport time, transport distance, or ambient ozone concentrations—the dispersion 

model will overpredict NO2 impacts. Conservative assumptions are initially used in 

compliance screening methodologies in order to assure compliance. As the compliance 

evaluation methodology becomes more sophisticated, the greater accuracy continues to 

assure compliance while allowing less conservative assumptions. EPA addresses this 

process, in the context of the 1-hour NO2 standard, through increasingly sophisticated 

(and less conservative) tiers of analysis. 

The regulatory default modeling methodologies for the 1-hour NO2 standard are 

screening methodologies.4

 

-7- 
Tier 1: Assume full conversion of NO to NO2 based on application of an 

appropriate refined modeling technique under Section 4.2.2 of Appendix W to 

estimate ambient NOx concentrations. 

Tier 2: Multiply Tier 1 result by an empirically derived NO2/NOx ratio, with 0.75 

as the annual national default ratio (called the Ambient Ratio Method [ARM]). 

Tier 3: Detailed screening methods may be considered on a case-by-case basis, 

with the Ozone Limiting Method (OLM) identified as a detailed screening 

technique for point sources. PVMRM is also considered by EPA to be in this 

category at this time.5

Consistent with EPA guidelines, the District has issued more detailed guidance that 

provides a four-tier approach to modeling that tests compliance with the 1-hour NO2

NAAQS. This tiered approach is described in detail below.6 

1. Tier I 

a. The maximum 1-hour NO2 concentration is modeled from all sources in a 

project using AERMOD, five years of meteorological data, and the 

assumption of complete conversion of NO to NO2. The maximum 

modeled concentration is added to the representative background 

concentration provided by the District. 

i. If the maximum combined concentration is less than the 1-hour 

NO2 NAAQS, the analysis is complete and compliance with the 

standard has been demonstrated. 

ii. If the maximum combined concentration exceeds the 1-hour NO2

NAAQS, then the maximum modeled concentration alone is 

compared to the interim SIL of 4 ppb. 

1. If the maximum modeled concentration is less than the SIL, 

then the analysis is complete and compliance with the 

standard has been demonstrated. 

2. If the maximum modeled concentration exceeds the SIL, 

then the analysis must continue as described next using an 

ARM value of 0.9 for the conversion of NO to NO2. 

b. The maximum 1-hour NO2 concentration is modeled from all sources in a 

project using AERMOD, five years of meteorological data, and the 

application of a default ARM value of 0.9 instead of complete conversion 

of NO to NO2. Again, the maximum modeled concentration is added to 

the representative background concentration provided by the District. 

i. If the maximum combined concentration is less than the 1-hour 

NO2 NAAQS, the analysis is complete and compliance with the 

standard has been demonstrated. 

-8- 
ii. If the maximum combined concentration exceeds the 1-hour NO2

NAAQS, then the maximum modeled concentration alone is 

compared to the interim SIL of 4 ppb. 

1. If the maximum modeled concentration is less than the SIL, 

then the analysis is complete and compliance with the 

standard has been demonstrated. 

2. If the maximum modeled concentration exceeds the SIL, 

then the analysis must continue as described next using 

AERMOD PVMRM or OLM. 

c. The maximum 1-hour NO2 concentration is modeled from all sources in a 

project using AERMOD PVMRM or OLM, and five years of 

meteorological data. The maximum modeled concentration is added to 

the representative background concentration provided by the District. 

i. If the maximum combined concentration is less than the 1-hour 

NO2 NAAQS, the analysis is complete and compliance with the 

standard has been demonstrated. 

ii. If the maximum combined concentration exceeds the 1-hour NO2

NAAQS, then the maximum modeled concentration alone is 

compared to the interim SIL of 4 ppb. 

1. If the maximum modeled concentration is less than the SIL, 

then the analysis is complete and compliance with the 

standard has been demonstrated. 

2. If the maximum modeled concentration exceeds the SIL, 

then the analysis must continue as described next in Tier 

II. 

2. Tier II: The Tier II method is identical to Tier I except that the 8th highest 

modeled concentration replaces the maximum modeled concentration in the 

analysis. 

3. Tier III: The 98th percentile 1-hour predicted concentration at each receptor is 

determined using the post-processor developed by the District, third-party 

software developers,a

 or an EPA-approved revised version of AERMOD. 

4. Tier IV: The predicted 1-hour NO2 concentrations from the model are paired in 

time with the monitored 1-hour NO2 concentrations. The same approach as 

identified above for Tier III is used to calculate a final concentration to compare 

with the standard. 

The Project’s May 13, 2010 submittal of the supplemental 1-hour NO2 air quality impact 

analysis used a Tier IV approach. The only difference between the May 13, 2010 

submission and the revised submission addressed by this protocol is that more recent 

meteorological and background ozone and NO2 data have been prepared by SJVAPCD, 

and utilize an updated data substitution methodology that complies with EPA and District 

requirements. The District’s data substitution methodology uses a conservative procedure 

 

a

 Sierra Research developed and used such a post-processor in preparing the May 13, 2010 submittal to 

EPA. 

-9- 
and results in a complete set of hourly data.7

 SJVAPCD requires the use of this data set 

for compliance demonstrations submitted for its review. 

Under EPA’s interim guidance for evaluating compliance with the 1-hour NO2 NAAQS, 

the proposed SIL-equivalent is so low that almost any moderate-to-large combustion 

source will have difficulty passing a screening assessment. It is therefore necessary to 

use more sophisticated analytical tools, as provided for in EPA guidance. One such tool 

identified by both EPA and the District, and selected for use with the Project, is the 

PVMRM option within AERMOD. 

AERMOD-PVMRM has been tested specifically for its ability to compute unbiased 

results. One of the key studies was conducted on a large natural gas-fired power plant by 

a senior modeler currently in the EPA’s Office of Air Quality Planning and Standards.8

 

The study concluded the following: “Based on all of the data available, the AERMODPVMRM algorithm is judged to provide unbiased estimates of the NO2/NOx ratio based 

on criteria that are comparable to, or more rigorous than, evaluations performed for other 

dispersion models that are judged to be refined.” 

In addition, the District conducted a careful review of both the PVMRM and OLM 

options in the implementation of AERMOD to demonstrate regulatory compliance of 

new sources.9

 The District evaluation took into account, and described compliance of the 

PVMRM option with, the following five requirements10 for approval to use an 

“alternative refined model,” as PVMRM is defined by EPA: 

i. The model has received a scientific peer review; 

ii. The model can be demonstrated to be applicable to the problem on a theoretical 

basis; 

iii. The data bases which are necessary to perform the analysis are available and 

adequate; 

iv. Appropriate performance evaluations of the model have shown that the model is 

not biased toward underestimates; and 

v. A protocol on methods and procedures to be followed has been established.11

The District evaluation of AERMOD-PVMRM concluded the following: “Based on the 

information provided above, the District has determined that the method for determining 

hourly NO2 concentrations using AERMOD in conjunction with the non-regulatory OLM 

or PVMRM options is acceptable based on the requirements in 40 CFR Part 51, 

Appendix W, 3.2.2(e)....”12

For all of the above reasons, the PVMRM option within AERMOD is demonstrably 

applicable to a refined analysis of 1-hour average NO2 impacts from the Project on a 

theoretical basis. The District’s August 19, 2010 guidance approves use of this model, 

and the District has used it to determine that the proposed Avenal Energy Project would 

not interfere with attainment or maintenance of the 1-hour NO2 NAAQS.13

-10- 
2.3 Receptor Grids

Receptor and source base elevations will be determined from USGS Digital Elevation 

Model (DEM) data using the 71⁄2-minute format (10- to 30-meter spacing between grid 

nodes). The 71⁄2-minute data will first be converted to an XYZ text file format to allow 

the modeling software to adjust Zone 11 coordinates to Zone 10 coordinates. 

In situations where modeling beyond 10 km distance is performed, then coarser, 1 degree 

DEM files will be used for elevation data. These files can be used directly by Lakes 

Environmental software, since they are not referenced to a UTM Zone, but rather to 

longitude/latitude. All coordinates will be referenced to UTM North American Datum 

1927 (NAD27), Zone 10. AERMOD receptor elevations will be interpolated among the 

DEM nodes according to standard AERMAP procedure, and hill heights will be 

determined for the purpose of computing concentrations in elevated terrain. 

Nested Cartesian coordinate receptor grids are developed to provide adequate spatial 

coverage surrounding the project area for assessing ground-level pollution 

concentrations, to identify the spatial extent of potentially significant impacts, and to 

identify maximum impact locations. The resolution and extent of each nested grid are as 

follows: 

• 25-meter resolution along the facility fence line in a single tier of receptors 

composed of four segments extending out to 100 meters from the fence line; 

• 100-meter resolution from 100 meters to 1,000 meters from the fence line; 

• 250-meter resolution from 1 km out to approximately 10 km from the site; and 

• 1,000-meter resolution from 10 km out to 50 km from the site. 

When maximum first-high or maximum second-high impacts occur in the 100-, 250-, or 

1,000-meter spaced areas, an additional refined receptor grid with 25-meter resolution is 

placed around each maximum coarse grid impact in the form of a rectangular area 

extending out to a distance of 1,000 meters (i.e., four 250-meter coarse grid spacings). 

Concentrations within the facility fence line are not calculated. 

The following 7.5-minute USGS DEM quadrangles in California are employed for 

modeling the Project out to a distance of 10 km: 

• Guijarral Hills; 

• Huron; 

• Westhaven; 

• Avenal; 

• La Cima; 

• Kettleman City; 

-11- 
• Garza Peak; 

• Kettleman Plain; and 

• Los Viejos. 

2.4 Data Requirements—Meteorological Data

The District has developed and posts on its website five years of pre-processed 

meteorological data from its monitoring station at Hanford, CA, located 28 miles to the 

northeast of the project site (see Figure 1), and appropriate for use on this project with the 

model AERMOD. Data from the Hanford station14 have been processed by AERMET 

software, which formats the data for use in AERMOD. The modeling in the original 

February 2008 application and the May 13, 2010 supplemental analysis both used 

Hanford meteorological data from 2000-2004, while the revised air dispersion modeling 

for testing compliance with the 1-hour NO2 NAAQS uses more recent Hanford 

meteorological data from 2005-2009. 

As stated in our May 13, 2010 submittal,3

 the District required use of, and the analysis 

used, meteorological data collected and prepared by the District from their Hanford 

monitoring station. The District, not the applicant, preprocessed the meteorological data 

using AERMET for use in AERMOD. The May 13 submittal stated the following: “The 

surface characteristics appropriate for the land uses surrounding the meteorological 

station at Hanford—namely surface roughness length, albedo, and Bowen Ratio—were 

computed by the District. The meteorological data set used for this analysis is unchanged 

from that used to develop the air quality impact analysis in the February 2008 PSD and 

FDOC permit applications.” 

The District provides the detailed surface characteristic information EPA requests for the 

Hanford meteorological station on pages 37-47 and 96 in Version 1.2 of its August 2006 

“Guidance for Air Dispersion Modeling.”15 The District believes that the procedure and 

resulting surface characteristic information for AERMET “in the vicinity of the 

meteorological tower” described therein was fully compliant with EPA requirements 

existing in 2006 for the 2000-2004 meteorological data used in the project modeling and 

ambient air quality impact analysis16 contained in the original February 2008 application 

and in the May 13, 2010 supplemental NO2 air quality impact analysis. The 

meteorological data from Hanford during the most recently available five-year period of 

2005-2009 were also processed by the District following all available guidance as listed 

above. The meteorological tower is located near the center of the north-northwest southsoutheast aligned runway. Roughly two-thirds of the area surrounding the tower is 

agriculture. 

The District believes that the surface characteristics (surface roughness, albedo, and 

Bowen ratio) near the project site are similar to those around the meteorological tower 

because the area on and around the project site is agricultural in use, as is the dominant 

portion (i.e., two-thirds) of the area around the meteorological tower. The similarity 

between the two locations, in terms of the three basic parameters required by AERMET, 

-12- 
increased for the processing of the more recent (i.e., 2005-2009) meteorological data 

provided by the District because EPA reduced the radius for the evaluation of surface 

characteristics from the 3 km used in processing the original 2000-2004 meteorological 

data set to 1 km, which was used to process the revised 2005-2009 meteorological data 

set. This reduction in radius removed from consideration much of the land use that was 

different between the two locations (i.e., suburban and urban land use).17

Both locations (the Project site and the location of the meteorological data station) have 

similar seasonal distributions of rainfall as shown in Table 1, with the maximum monthly 

rainfall occurring in January and no monthly rainfall in July and August.

http://www.worldclimate.com/cgi-bin/data.pl?ref=N36W119+2200+043747C) 

Relative to the Hanford meteorological monitoring site, the climatology of Hanford and 

the Avenal Energy Project site are closely similar because of the following factors: 

1. Both sites are in the same county (Kings County) and the same flat Central 

Valley, separated by only 28 miles. 

2. Both sites are accurately described by the same climatology contained in the 

original February 2008 application submitted to the EPA, CEC and SJVAPCD, as 

follows: 

-13- 
USEPA defines the term ‘on-site data’ to mean data that would be 

representative of atmospheric dispersion conditions at the source and at 

locations where the source may have a significant impact on air quality. 

Specifically, the meteorological data requirement originates in the Clean 

Air Act at Section 165(e)(1), which requires an analysis ‘of the ambient 

air quality at the proposed site and in areas which may be affected by 

emissions from such facility for each pollutant subject to regulation under 

[the Act] which will be emitted from such facility.’

This requirement and EPA’s guidance on the use of on-site monitoring data are 

also outlined in the “On-Site Meteorological Program Guidance for Regulatory 

Modeling Applications.”18 The representativeness of the data depends on (a) the 

proximity of the meteorological monitoring site to the area under consideration, 

(b) the complexity of the topography of the area, (c) the exposure of the 

meteorological sensors, and (d) the period of time during which the data are 

collected. The District’s Hanford meteorological data are representative of 

conditions at the project site relative to these four factors as follows: 

a) The meteorological monitoring station is 28 miles from the project site on 

a flat valley; 

b) The topography at and between the two sites is flat; 

c) The meteorological sensors are located near the center of the northnorthwest/south-southeast aligned runway at the Hanford airport, giving 

them the same unobstructed exposure to wind that would be experienced 

at the Project site; and 

The five years of meteorological data used in the original supplemental modeling 

submissions (2000-2004) were coincident with the ambient ozone data used 

therein. The first three years (2005-2007) of the five years (2005-2009) of 

meteorological data used in the revised modeling submittal are coincident with 

the ambient ozone and NO2 data monitored at Hanford. For the remaining two 

years (2008-2009), Visalia ozone and NO2 ambient data are used with Hanford 

meteorological data for the 1-hour NO2 analysis, as recommended by the 

District.13 

Representativeness has also been defined in the “Workshop on the 

Representativeness of Meteorological Observations”19 as “the extent to which a 

set of measurements taken in a space-time domain reflects the actual conditions in 

the same or different space-time domain taken on a scale appropriate for a 

specific application.” Representativeness is best evaluated when sites are 

climatologically similar, as are the project site and the Hanford meteorological 

monitoring station. Representativeness has additionally been defined in the PSD 

Monitoring Guideline20 as data that characterize the air quality for the general 

area in which the proposed project would be constructed and operated. Because 

of the relative proximity of the Hanford meteorological data site to the proposed 

project site, the same large-scale topographic features that influence the 

-14- 
meteorological data monitoring station also influence the proposed project site in 

the same manner.21

Further to the climatological similarity of the project site and the meteorological 

monitoring site is the following climate information, taken from Section 6.2.1.2 of the 

February 2008 application:22

The climate of the San Joaquin Valley is characterized by hot summers, mild 

winters, and small amounts of precipitation. The major climatic controls in the 

Valley are the mountains on three sides and the semi-permanent Pacific High 

pressure system over the eastern Pacific Ocean. The Great Basin High pressure 

system to the east also affects the Valley, primarily during the winter months. 

These synoptic scale influences result in distinct seasonal weather characteristics, 

as discussed below. 

The Pacific High is a semi-permanent subtropical high pressure system located 

off the Pacific Coast. It is centered between the 140°W and 150°W meridians, 

and oscillates in a north-south direction seasonally. During the summer, it moves 

northward and dominates the regional climate, producing persistent temperature 

inversions and a predominantly southwesterly wind field. Clear skies, high 

temperatures, and low humidity characterize this season. Precipitation rarely 

occurs during summer months, because migrating storm systems are blocked by 

the Pacific High. Occasionally, however, tropical air moves into the area and 

thunderstorms may occur over the adjacent mountains. 

In the fall, the Pacific High weakens and shifts southwestward toward Hawaii, 

and its dominance is diminished in the San Joaquin Valley. During the transition 

period, the storm belt and zone of strong westerly winds also moves southward 

into California. The prevailing weather patterns during this time of year include 

storm periods with rain and gusty winds, clear weather that can occur after a 

storm or because of the Great Basin High pressure area, or persistent fog caused 

by temperature inversion. The average annual rainfall at the site is 

approximately 7 inches, of which approximately 70% falls in the four months of 

December through March. Temperature, winds, and rainfall are more variable 

during the fall and winter months, but also stagnant conditions occur more 

frequently than during summer. (Climates of the States – California, U.S. 

Department of Commerce, Weather Bureau, 1959.) 

Wind and mixing height are two key meteorological parameters that govern the 

potential for air pollution problems. The predominant winds in California are 

shown in Figures 6.2-1 through 6.2-4. (The Uses of Meteorological Data in 

Large-Scale Air Pollution Surveys, Stanford Research Institute, 1958). As the 

figures indicate, winds in California are generally light and easterly in the winter, 

but strong and westerly in the spring, summer, and fall. 

-15- 
Wind patterns in the general area of the project site are presented in Figures 6.2-

5a through 5y, which show annual and quarterly wind roses for the Hanford, 

California monitoring station. Hanford is approximately 28 miles northeast of 

the site, and is the closest station for air quality and meteorological monitoring 

(discussed in more detail in Sections 6.2.3 and 6.2.5, respectively. Approximately 

half of all winds come from the northwest quadrant, and calm winds occur 

approximately one-quarter of the time. [see Figures 2A through 2E] 

 

Concerning mixing heights, inland areas, where marine influence is weak or 

nonexistent, experience strong ground-based inversions, which inhibit mixing and 

can result in high pollutant concentrations. An example case available from the 

central part of the San Joaquin Valley is Fresno. Smith, et al (1984), reported 

that at Fresno, 50th percentile morning mixing heights for the period 1979-80 

were 115-150 meters (approximately 375-495 feet) in the fall and winter, 230 

meters (755 feet) in the spring, and 175 meters (575 feet) in the summer. Such 

low morning mixing heights trap pollutants, at least during the morning. The 

50th percentile afternoon mixing heights, however, were unlimited in spring and 

summer, 1135 meters (3,725 feet) in the fall, and 630 meters (2,065 feet) in the 

winter. Such mixing heights provide generally favorable conditions for the 

dispersion of pollutants.

The representativeness of the Hanford meteorological data was also justified in the 

discussion contained in the air dispersion modeling protocol submitted to Region 9 in 

August 2007. That analysis is summarized below. 

The meteorological data from the Hanford monitoring station are representative 

of conditions at the Project because the area is extremely flat both between the 

two locations and over a much larger area to the northwest and southeast along 

the alignment of the San Joaquin Valley. Air flow in the valley (including both 

locations) can be characterized by up-valley and down-valley winds. The downvalley winds are generally a result of airflow into the Valley from the Carquinez 

Strait and the Altamont Pass that then flow south. Strong diurnal wind regimes 

markedly affect the horizontal transport of air in the project area. This results in 

a pronounced north-northwest component to the wind roses shown in Figures 2A 

through 2E for 2000-2004, respectively. [updated for 2005-2009 in Figures 2A 

through 2E herein] Modeling for each of the five years of available data23 will not 

vary much because the meteorological data are so constant between the years.24

Because of the relative proximity of the Hanford meteorological data site to the proposed 

project site, the same large-scale topographic features that influence the meteorological 

data monitoring station also influence the proposed project site in the same manner. 

The upper air data (from Oakland Metropolitan Airport, ID No. 23230) are necessarily 

representative of a large geographic domain because of the large distances between upper 

air meteorological monitoring stations. These upper air data also reasonably represent 

conditions at the higher altitudes of plumes from large sources such as the proposed F-

-16- 
Class combustion gas turbines. Upper air data from the Oakland site were also used by 

the District in processing the Hanford meteorological data for use with AERMOD. 

This analysis, and the use of the Hanford station meteorological data as representative of 

the Project site, was accepted by EPA for purposes of analysis of the Project’s impacts on 

the 1-hour and 8-hour CO standards, the 24-hour average PM10 standards, and the annual 

average NO2 standard.25 The same meteorological data that have been accepted as 

representative for these pollutants are also representative in the context of a 1-hour NO2

standard.

2.5 Data Requirements—Ambient Monitoring Data

Ambient NO2 data collected during the three-year period of 2005-2007 at the Hanford 

monitoring station and during 2008-2009 at the Visalia monitoring station are used to 

characterize the representative ambient background concentrations. The ambient 

pollution levels monitored at the Hanford and Visalia monitoring stations represent areawide ambient conditions rather than the localized impacts of any particular facility due to 

the lack of any large local industrial sources in either area. Because the NO2 monitor was 

removed from the Hanford station before annually complete data could be collected for 

2008 and 2009, the District recommends use of the NO2 monitoring data collected in 

Visalia during these last two years of the five-year dataset to be used in modeling.26

Computation of hourly NO2 impacts from the Project also requires use of ambient 

monitored hourly O3 concentrations. The PVMRM adaptation of the Ozone Limiting 

Method27 is used to determine the extent to which the NO emitted from the exhaust 

stacks is converted to NO2 when it reaches the ground. AERMOD PVMRM calculates 

the NO2 concentration using hourly O3 data. Hourly O3 data collected at the same 

Hanford monitoring station during the years 2005-2007 and during 2008-2009 at the 

Visalia monitoring station are used in conjunction with PVMRM to calculate hourly NO2

concentrations from hourly NOx concentrations. 

2.5.1 Data Substitution—Ozone

Data substitution for missing hourly O3 and NO2 ambient monitoring data requires 

different data substitution procedures because the two data sets serve different purposes. 

The District substituted for missing hourly ambient O3 concentrations using the 

procedure described below.28

• If a single value was missing, the District interpolated between the values for the 

hour before and the hour after the hour of the missing value using the same 

procedure as that outlined by EPA29 for meteorological data. 

• If multiple hours had missing values, the District substituted a value of 40 ppbv 

for missing data. 

The District used, and recommended, the Visalia O3 monitoring data from 2008-2009 to 

supplement the Hanford O3 monitoring data from 2005-2007, so as to create a five-year 

dataset for use in modeling with AERMOD PVMRM. In doing so, the District adhered 

to its guidance as follows: 

-22- 
2.5.2 Data Substitution—NO2

Unlike the O3 data that are used by the dispersion model to determine modeled impacts, 

the NO2 ambient data are used to establish the baseline ambient conditions for the Project 

impact area. As such, based on EPA guidance related to determinations of ambient 

monitoring compliance with the 1-hour NO2 NAAQS,30 the District performed data 

substitution for NO2 as follows:9

• If a single value was missing, the District interpolated between the values for the 

hour before and hour after the hour with the missing value using the same 

procedure as that outlined by EPA29 for meteorological data. 

• If multiple hours had missing values, the District set the value to the maximum 1-

hour NO2 concentration recorded during the same quarter. 

The District’s data substitution approach results in a very conservative response to the 

issue of missing data. All hours with missing NO2 values are treated as if the seasonal 

maximum concentration applied, regardless of time of day or meteorological conditions. 

2.6 Identification of Nearby Sources

A screening process was used to identify potential nearby sources to be included in the 1-

hour NO2 NAAQS analysis.That analysis was designed to identify sources that are not 

adequately represented by ambient NO2 concentrations monitored at Hanford, and must 

therefore be explicitly modeled. 

To determine whether any new sources had been approved, but not reflected in the 

ambient monitoring data, the District was requested31 to list all projects within 6 miles of 

the project sitea

 “which received construction permits but are not yet operating, or are in 

the permitting process.” Sources with permitted emissions of less than 5 tons per year 

were also excluded.b No nearby sources were identified using this approach. 

In addition, to determine whether any existing sources should be explicitly modeled 

because they could potentially have significant impacts at the time and place that the 

project has significant impacts, but are not adequately represented by the ambient 

monitoring data, the following screening procedure was used. 

 

a

 California Energy Commission. “ATTACHMENT B - ENERGY COMMISSION STAFF’S DATA 

ADEQUACY WORKSHEET for Air Quality,” Energy Facilities Siting Division, March 2007. The CEC 

has determined, based on its modeling experience, that there is no statistically significant concentration 

overlap for non-reactive pollutant concentrations between two stationary emission sources beyond six 

miles. See, for example, CEC, Hanford Energy Park Peaker Staff Report, Oct. 2009, p. 4.1-25. b

 CEC has determined, based on its modeling experience, that emission sources with emissions below 5 

tons per year are unlikely to significantly contribute to cumulative air quality emission impacts. See, for 

example, CEC, Modesto Irrigation District Woodland Generation Station 2 Commission Decision, Sep. 

2001, p. 4-24. 

-23- 
EPA has considered and accepted several methods for screening sources for inclusion in 

the NAAQS inventory. These are summarized in the meeting notes for an 

EPA/State/Local PSD Workshop held in New Orleans in May 2005.32 As discussed in 

the workshop notes: 

The concept of “significant concentration gradient” is used to catch all instances 

not represented by “regional” monitored concentrations, added to the combined 

sources’ impacts to determine total impacts, which could interact with the 

proposed source’s impacts. However, without some practical limitations, such 

gradients can occur anywhere in the “vicinity” of the sources defined by the SIA 

and could lead to a large and, at times, unnecessary resource expenditures. Thus, 

in order to balance the need for identifying all sources which meet the criteria in 

the Guideline and also to achieve a workable inventory of sources, various 

permitting agencies have developed and used objective tools to assist in the 

determination of an emission inventory. A 1992 EPA/States modelers workgroup 

considered some of these approaches and concluded that all such tools should be 

used by the reviewing authority on a case by case basis to compliment [sic] their 

professional judgment in developing an inventory of nearby sources.32

We have applied the “20D method,” developed by North Carolina to screen sources for 

the inventory. The “20D Method” is one of the earliest methods developed for 

identifying nearby sources with the potential to result in impacts not captured by regional 

monitoring. The method relies on a formula derived as 20 times the distance to the 

source. The method suggests including those sources within the screening analysis for 

which Q > 20D, where Q is the maximum emission (in tons per year) for the source being 

screened, and, for short-term analyses, D is the distance (in kilometers) from the source 

being screened to the PSD source. For the purposes of this method, the source is defined 

as the facility or complex, not an individual stack or other emission point. 

We considered using the PSD definition of a significant emissions increase for NOx 

emissions (40 tons per year [tpy]) as a de minimis threshold for excluding a source from 

consideration. However, we chose to use a much lower threshold of 5 tpy in order to be 

consistent with the CEC criteria for cumulative impact analyses, and to assure that the 

analysis was sufficiently conservative to address EPA’s concerns. This value is 

consistent with past guidance from EPA Region 9.33

Emission sources were located using the California ARB CHAPIS web site 

(www.arb.ca.gov/chapis), which graphically displays all sources that met one or more of 

the following in 2001: 

a. Sources that emitted at least 10 tons of VOC, NOx, SOx, CO, or PM10; 

b. Power plants rated at 50 MW or greater; or 

c. Air Toxic “Hot Spots” facilities in the categories of (1) metal fabrication; 

(2) aerospace/electronics; and (3) chemical plants. 

-24- 
 ARB’s Facility Search Tool (http://www.arb.ca.gov/app/emsinv/facinfo/facinfo.php?dd) 

was used to determine whether any relevant sources in the 2008 inventory had been 

overlooked. 

The results of this analysis are shown in Table 2, which shows that there are no facilities 

both large enough and close enough to the project to be included in the NAAQS 

inventory. All sources are far enough away that it is unlikely that impacts will interact 

significantly with project’s short term impacts.

2.7 Combining Existing Ambient Air Quality Data with Modeled Impacts

Modeled concentrations are added to background NO2 concentrations to determine total 

concentrations for comparison with the new NAAQS using the procedure summarized 

below. 

• As described above, the impacts of the project at each receptor in the study area 

and for each hour in the analysis period are modeled using AERMOD. 

• The predicted total hourly NO2 concentration at each receptor is calculated by 

adding the modeled hourly project impact at the receptor to the corresponding 

hour NO2 concentration measured at the Hanford ambient air quality monitoring 

station for 2005-2007, and at the Visalia station for 2008-2009. 

• Because the District NO2 data were processed according to EPA guidance and 

four complete quarters are available, resulting in each year being complete, the 

98th percentile daily maximum total hourly NO2 concentration is the 8th highest 

value determined for that year for each receptor. 

• At each receptor, the 98th percentile daily maximum concentrations are averaged 

across the five-year period in the analysis period. 

• From the field of receptors, the receptor with the highest five-year average is 

selected to represent the maximum total hourly NO2 concentration for the project 

impact area. This maximum total hourly NO2 concentration is converted from 

μg/m3 to ppb using the annual NO2 NAAQS conversion ratio of 100 μg/m3 = 

53 ppb. The result is rounded to the nearest ppb and compared to the new 

one-hour NO2 NAAQS. 

Sierra Research has developed a postprocessor in FORTRAN to perform these 

calculations. The postprocessor uses the two following input files: 

• AERMOD 1-hour average NO2 DAYTABLEa

 output file (processed with 

PVMRM); and 

• Hourly ambient background NO2 concentrations (in units of μg/m3). 

To allow the postprocessor to handle the large DAYTABLE output files for tens of 

thousands of receptors in the grids and the five years of hourly meteorological data, the 

postprocessor reads and processes concentrations from both files in 24-hour blocks. The 

AERMOD output file is read, receptor by receptor, for each hour. Then the background 

 

a

 The February 25, 2010 EPA “Notice Regarding Modeling for New Hourly NO2 NAAQS” suggests the 

same computational post-processing with the AERMOD-generated POSTFILE 

(http://www.epa.gov/scram001/no2_hourly_NAAQS_aermod_02-25-10.pdf). The AERMOD generated 

DAYTABLE and POSTFILE contain identical data, but in different formats. 

-27- 
concentration is read for that hour and added to the modeled concentration. Once the 

daily maxima are determined for each receptor for the entire year, two tables are 

generated. The first table calculated is the daily maxima for all receptors, and becomes 

the first output table from the postprocessor. 

The daily maxima for each receptor are sorted by the postprocessor through use of the 

HEAPSORT utility from Numerical Recipes.34 The second table is calculated, and 

output for the eight highest daily maximum concentrations for each receptor (tagged by 

Julian day) is generated. 

At each receptor, the 98th percentile daily maximum concentrations are averaged across 

the five-year (2005-2009) analysis period. Examination of the second table yields the 

highest 8th-highest concentration from among all the receptors, for comparison to the 

federal standard.
