Fort Worth Natural Gas Air Quality Study Final Work Plan
INTRODUCTION
This document contains Eastern Research Group's (ERG's) work plan for performing the
tasks and activities specified in Project DEM 10-05 (Natural Gas Air Quality Study). The
primary objectives of this project are to answer these fundamental questions:
What quantity of emissions (on a volume and mass basis) is coming from natural
gas exploration and production sites located within the City of Fort Worth?
Do the sites comply with applicable regulatory limits?
What effect do emissions from natural gas exploration and production activities
have on ambient air quality at the fenceline?
Are the City's setbacks for wells, tanks, and compressors adequate to protect
public health?
This work plan addresses each of the tasks that must be completed in order to answer the
questions above for the City of Fort Worth(the City), to ensure that the public is kept informed
throughout the duration of the project, and to prepare a final report, including findings,
conclusions, and recommendations. Under this work plan, we will implement the Ambient Air
Monitoring Network Design and Point Source Testing Plan that were developed under a separate
contract entitled "Fort Worth Natural Gas Air Quality Study Planning".
To assist ERG in completing this project, Sage Environmental Consulting will be leading
the point source testing task (Task 3) and providing technical peer review on all project tasks.
Also, Hicks & Company (certified by the North Central Texas Regional Certification Agency
(NCTRCA) as a Woman-Owned Business Enterprise) will be providing field sampling support.
A description of each of the project tasks is provided below in Sections 1 through 7,
Section 8 provides a project time line, and Section 9 provides budget information for each task.
Specific references to the four questions above are embedded in the discussion of each section
showing how the tasks relate to meeting the objectives of the project. Section 9 also identifies
each member of the project team and their estimated hours of participation in this project and
designates Sage and Hicks staff specifically.
1.0 TASK 1 —PROJECT MANAGEMENT
This task will be used by the Project Manager (PM), the Senior Peer Reviewer, and
administrative support staff to ensure this project is executed in a technically competent manner,
in a timely fashion, and within the proposed budget; to prepare monthly progress reports and
invoices; and to maintain communication with the City on overall project schedule and budget.
The PM for this project is Mr. Mike Pring. In this role, he will be responsible for
directing this project's day-to-day activities. Mr. Pring will be the central point of contact for the
City and will have overall authority and responsibility for ERG's performance on the proposed
program. He will be available to City staff on a daily basis to discuss and resolve any issues
regarding schedule, cost, or labor commitment. Mr. Pring will be available to consult with the
1

Fort Worth Natural Gas Air Quality Study Final Work Plan
ERG staff and attend meetings where his knowledge and broad technical perspective on air
quality issues as related to oil and gas exploration and production will be beneficial.
Contact information for Mr. Pring is as follows:
Telephone: 919-468-7840
Fax: 919-468-7801
Email: Mike.Pring @erg.com
The Senior Peer Reviewer for this project is Art Bedrosian of Sage Environmental
Consulting, who will provide peer review on all project tasks. Mr. Bedrosian has extensive
experience in all aspects of this project and will serve as a technical resource and in an advisory
role as the project progresses.
The cost estimate for this task is $22,020, based on a total project period of 8 months
(August, 2010 through March 2011). Details on the cost breakdown are provided in Table 8.
2.0 TASK 2—AMBIENT AIR MONITORING
0 What effect do emissions from natural gas exploration and production activities have
on ambient air quality at the fenceline?
0 Are the City's setbacks for wells, tanks, and compressors adequate to protect public
health?
Task 2 involves the establishment of an ambient air monitoring network within the City
to quantify the concentration of volatile organic compounds (VOCs) and hazardous air pollutants
(HAPs) (such as benzene and formaldehyde) in the ambient air to assist in answering the
questions above.
Task Overview
The primary purpose for this task is to determine the prevalence and magnitude of
specific air toxics compounds in the ambient air at monitoring sites in accordance with
applicable set-backs. This data will be used to conduct a public health evaluation as described
under Task 6. As a related task, the City is interested in understanding the behavior of ambient
methane and ethane, specifically related to benzene concentration levels.
In this task, the ERG Team will use the results of the planning study to implement the air
toxics monitoring network which will be located throughout the City. During this time, we will:
1) work with the City to gain access to proposed sites; 2) distribute and review project-specific
standard operating procedures (SOPS) to field technicians to ensure consistent sample acquisition
and handling; 3) install certified monitoring equipment; and 4) make adjustments to the Quality
Assurance Project Plan (QAPP) if the technical nature of the Data Quality Objectives (DQOs)
has been adjusted.

Pollutants of Interest
As stated in the above primary objective of this study, we are proposing sampling for
specific air toxics of:
VOCs as identified by EPA's method TO-15 (including benzene);
Carbonyl compounds identified by EPA's method TO-11A (including
formaldehyde);
0 Speciated non-methane organic compounds (SNMOC), as identified by
ERG/SNMOC Analysis Method; and
0 Methane, as identified by EPA's method TO-14.
The list of air toxics that will be reported from these sampling methods are listed in
Tables 1-3. These three compound groups provide over 130 air toxics, including 45 hazardous air
pollutants (HAPs), such as benzene, ethylbenzene, toluene, and xylenes (BTEX compounds),
formaldehyde, and acetaldehyde. All HAPs are denoted with a bold typeface in each of the
tables. From a toxicity standpoint, concentrations of benzene will be of primary importance for
this study.

The above pollutants also include important non-HAPs that will be useful in
characterizing and differentiating between emissions from natural gas activities (such as ethane
and other straight-chain hydrocarbons), mobile source activities (such as tent-Amyl Methyl
Ether, acetylene, ethylene, ethyl-tert-butyl ether), other industrial processes (such as methyl ethyl
ketone from surface coating operations or propylene from petrochemical manufacturing sources),
and from biogenic sources (such as isoprene). Generally speaking, however, the list of analytes is
specific to the analytical method and not to the target source type (e.g., natural gas sources and
mobile source).

Ambient Monitoring Network and Site Objectives
Prior to setting up the monitoring network, we will use the findings from work conducted
under a separate contract(Fort Worth Natural Gas Air Quality Planning Study) to identify
locations of potential monitoring sites. We will attempt to place monitoring sites as close to
applicable set-backs as possible, given logistical challenges such as accessibility to sites, security
concerns, and/or airflow obstructions such as sound blankets. Each site will be dispersed
geographically throughout the City to characterize as many natural gas sites as possible. For
example, a monitoring site located in an area of high level of natural gas activity can effectively
represent typical airshed conditions for up to a few miles, depending upon typical wind
conditions. Using that information, we can estimate a percentage of the total well pads that are
represented by the proposed monitoring network.
We are proposing setting up an air toxics monitoring network of seven sites with the
following objectives:
0 Site 1: Fixed site, located in a remotely populated area to be used as a background
site (the concentrations measured at this site will be useful for comparisons and
for calculating upwind-downwind concentration differences);
0 Site 2: Fixed site, located in a populated area with a moderate level of natural gas
activity conducted upwind;
0 Site 3: Fixed site, located in a populated area with a moderate level of natural gas
activity conducted upwind;
0 Site 4: Fixed site, located in a populated area near a high level of mobile source
activity(this is important to differentiate potential health impacts due to mobile
sources versus natural gas sources);
0 Site 5: Fixed site, located in a populated area where a high level of natural gas
activities are conducted upwind;
0 Site 6: Fixed site, located in a populated area where a high level of natural gas
activities are conducted upwind; and
0 Site 7: Fixed site, to be located initially at a pre-production operation such as a
drilling, fracturing, or completion site, or at other areas of interest. This site may
be relocated during the course of the project to a site in various stages of pre-
production.
This type of network design has been utilized in our work for many of our Agency for
Toxic Substances and Disease Registry's (ATSDR) exposure investigations, which included two
studies characterizing ambient air impacts from oil and natural gas wells. Using the above
network design (up to five sites dedicated to characterizing ambient air from natural gas
activities, a remote background site, and a site close to mobile source activity), we are confident
that we will be able to evaluate the impacts of natural gas activity as close to the setbacks as
possible in a scientifically defensible manner.

Sampling Frequency
During this study, ERG is proposing sampling every 1 in 3 days at each of these sites.
Over the course of two months, this short-term sampling schedule will yield approximately
20 sampling days, which we believe is a sufficient number of data points to calculate an estimate
of long-term concentrations for a number of air toxics. This type of"short-term" average is
currently being used by EPA in their evaluation of monitoring data for the Schools Air Toxics
Initiative. These estimates will then be compared to various public health exposure levels to
assist in determining whether or not we recommend that monitoring be extended to an annual
period.
Each sample conducted will be 24-hour samples targeting VOCs and SNMOC. Specific
monitoring at the sites will be:
1) Three fixed sites collecting integrated 24-hour whole air samples for concurrent
analysis resolving TO-15 and SNMOC target compounds. These sites would use
the Veriflow collection technology and not require sheltering or 110vAC power.
Collection frequency is 1-in-3 days for every site.
2) Two fixed sites collecting integrated 24-hour whole air samples for concurrent
analysis resolving TO-15 and SNMOC target compounds and integrated 24-hour
whole air samples for TO-I IA target compounds. All duplicate collections for
A.T./SNMOC and Carbonyls would be conducted at these sites also. These sites
would use conventional collection technology and would require sheltering,
temperature control, and 110vAC electric power. Collection frequency is 1-in-3
days for every site.
3) Two fixed sites collecting integrated 24-hour whole air samples for Methane and
air toxics analyses. These sites would use the Veriflow collection technology and
not require sheltering or 110vAC power. Collection frequency is 1-in-3 days for
every site.
Table 4 presents the sampling schedule.

Pre-Field Operations
In this section, ERG describes pre-field activities which will occur prior to sampling
initiation, which include:
1) ERG will check-out, certify (as required), calibrate (as required), all equipment
that will be deployed to the field.
2) ERG will ship the field collection systems to the field for deployment,
approximately 9 days prior to the first scheduled sampling event. This shipment
will include everything required to assemble and install the 7 sample collection
systems. This would include all system components, ancillary materials (i.e.,
fittings, stainless steel tubing, timers, chargers, etc.), associated Standard
Operating Procedures, and tools. The only materials/items envisioned for
7
Professional Services Contract Page 28 of 73
Air Quality Study-Final Work Plan
Eastern Research Group, Inc.
Fort Worth Natural Gas Air Quality Study Final Work Plan
purchase in the field would be those that are required do to specific site
considerations after site inspections have been performed.
3) ERG will travel to study location and install and check-out the sample collection
systems at each site approximately 7 days prior to the first scheduled collection
event.
4) ERG will train all field staff in the proper operation of the five Timer/Veriflow
collection systems and the two Canister/Carbonyl collection systems, and the
required procedure for collecting valid representative samples using these
systems.
5) ERG will train field staff in the proper procedures for receiving, handling, and
shipping samples media.
6) ERG will travel to study location and install and recover the sample collection
systems at each site approximately 3 days after the last scheduled collection
event, and ship this equipment back to the ERG Laboratory.
7) Upon receipt, ERG will repair/refurbish all field equipment as required.
Field Operations
In this section, ERG describes field activities which will occur as part of normal sample
pre-collection procedures and operations associated with collecting Air Toxics VOC and
Carbonyl Compounds samples on a 1-in-3 day frequency.
1) Approximately 1 week prior to each scheduled collection event, the field operator
will receive via Federal Express a shipment of prepared media (i.e., cleaned
evacuated 6-L SUMMA canisters and or DNPH Carbonyl tubes) in quantities
consistent with conducting an entire weeks worth of field sample collections. The
DNPH Carbonyl tubes will be shipped in a cooler with blue ice. They will be
placed in a refrigerator at the common staging area until ready for use collecting
field samples. The blue ice will be placed in a freezer until ready for re-use
shipping the samples back to the laboratory. Along with the media, specific
associated multi-copy Chain-of-Custody(COC) forms will be provided. The COC
forms will already have all laboratory origination information completed on them.
2) Two days prior to each scheduled sampling event, for the canister collection
systems that are battery powered, the operator will charge the digital control
timers using the transformers provided for each system. The charging will occur
at the common staging location.
3) One day prior to each collection event, a field operator will visit each site to
perform the following:
a. Carefully transport and deploy each of the battery operated canister
collection systems (at locations where fixed systems are not deployed);
b. Install new collection media (i.e., cleaned evacuated 6-L SUMMA canister
for battery operated sites and cleaned evacuated 6-L SUMMA canisters
and DNPH Carbonyl tubes for fixed system sites);
C. Program the digital timer to initiate sampling at 00:01 and terminate
sampling at 11:59on the date of the scheduled event;
8
Professional Services Contract Page 29 of 73
Air Quality Study-Final Work Plan
Eastern Research Group, Inc.
Fort Worth Natural Gas Air Quality Study Final Work Plan
d. Enable collection for each media type (e.g., open canister bellows valve);
and
e. Complete all associated paper work including completion of pre-collection
COC information (e.g., document initial canister pressure, document
initial DNPH carbonyl tube collection flow rate, etc.) and site log book
entries.
Post-collection Field Operations
In this section, ERG describes field activities which will occur as part of normal sample
post-collection procedures and operations associated with collecting Air Toxics VOC and
Carbonyl Compounds samples on a 1-in-3 day frequency.
1) One day after each collection event, a field operator will visit each site to perform
the following:
a. Inspect the site for anything unusual (e.g., damagedibroken equipment,
vandalism, evidence of tampering, etc.). If problems are noted, the
operator will immediately contact the ERG Project Manager and the
pertinent City staff to report the problems. At that time, a corrective action
may occur (i.e.,resample, relocating the equipment, etc.). If no problems
are observed, then proceed to the next step;
b. Disable collection for each media type (e.g., close canister bellows valve,
ensure that each canister inlet valve port is capped);
C. Complete all associated paper work including completion of post-
collection COC information (e.g., document final canister pressure,
document final DNPH carbonyl tube collection flow rate, document
elapsed time, etc.) and site log book entries. If final canister pressure
and/or flow rate do not meet the method criteria, then the operator will
notify the ERG Project Manager immediately. If possible, a make-up
sample may be taken immediately. If there are no problems with the
sample collection, proceed to the next step;
d. Recover collection media (i.e., whole air canister samples for battery
operated sites and whole air canister and DNPH Carbonyl samples for
fixed system sites).
2) Carefully transport each of the battery operated canister collection systems (from
locations were fixed systems are not deployed) and recovered sample media back
to the common staging area.
3) Place the DNPH Carbonyl samples in the refrigerator at the common staging area
until they are ready to be shipped back to the laboratory for analysis.
At this point steps the operator is ready to begin the Pre-collection steps in preparation
for the next collection event.

Sample Shipping
In this section, ERG describes sample shipping activities which will occur as part of
normal sample post-collection procedures and operations associated with collecting Air Toxics
VOC and Carbonyl Compounds samples on a 1-in-3 day frequency.
1) One day after each sample collection, place a canister sample and its associated
COC inside of the large bubble bag provided with each canister. Place the bagged
canister inside the shipping box provided with each canister. Secure the shipping
box with the packing tape provided.
2) Place one events worth of DNPH Carbonyl samples in a zip lock baggie. Place
their associated COCs in another zip lock baggie. Place the two baggier in the
small cooler as provided. Place blue ice in the cooler as provided.
3) Complete a Federal Express (FedEx) preprinted bill of laden (i.e., over night
service) for each canister sample shipping box and each DNPH Carbonyl samples
cooler prepared for shipment. Secure the bill of laden to each parcel.
4) Have parcels picked up by FedEx, or deliver the parcels to FedEx, for overnight
shipment the same day that they are prepared.
Sample Handling, Tracking, Analysis, and Reporting
In this section, ERG describes laboratory activities which will occur as part of normal
sample handling, tracking, analysis, and reporting Air Toxics VOC and Carbonyl Compounds
samples.
1) The day after they are shipped from the field, samples will be delivered to the
loading dock at ERG's laboratory complex. A dedicated receiving specialist will
take custody of the parcels. Each sample will be inspected to ensure that it arrived
intact and to establish that the validity of the sample was not compromised in any
way during shipment.
2) The receiving specialist will complete all associated paper work including as
received COC information (e.g., document as received canister pressure, calculate
and document DNPH carbonyl sample total collection volume, etc.) and receiving
log book entries.
3) The receiving specialist will then log each sample into ERG's state-of-the-art
Laboratory Information Management System(LIMS). During sample login, each
sample will receive the following (this information allows the sample to be
tracked and status-checked throughout all laboratory process):
a. A unique sample identification number;
b. A hatching descriptor specifying specifically what analyses the sample is
to undergo and data turn-around time requirements.
4) Air Toxics samples will be prepared and analyzed in strict accordance with the
guidelines presented in EPA Compendium Method TO-15 and the EPA NATTS
Technical Assistance Document (TAD). Speciated Nonmethane Organic
Compounds analyses will be performed in accordance with the guidelines
presented in the EPA Carbon Bond 4 Method and the EPA Ozone Precursors

5) Raw data is transmitted electronically from each analytical system directly to
ERG's LIMS. Within LIMS, the raw analytical data is converted into quantitated
measurement values.
6) ERG employs a robust multi-check, multi-level data review process to ensure that
all data generated is valid and representative.
7) Data is generated in a form that is easily imported into spreadsheets (e.g.
Microsoft Excel) or database management programs (e.g. Microsoft Access or
SQL).
8) Data quality will be assessed as follows:
a. Precision will be assessed by analyzing collocated samples from the fixed
monitoring sites in replicate (i.e., nested). The CV provides a relative
measure of variability by expressing standard deviations to the magnitude
of the arithmetic mean. The lower the CV, the less likelihood that
analytical results would vary due to sampling error.
b. Bias will be assessed by analyzing blind performance evaluation (PE)
samples as provided by EPA as part of the National Monitoring Programs.
Bias will be expressed in terms of relative percent difference (RPD). ERG
regularly receives these blind PE samples from EPA and the associated
performance data provided by EPA will be made available for this study.
The cost estimate for this task is $228,071. Details on the cost breakdown are provided in

3.0 TASK 3—POINT SOURCE TESTING
0 What quantity of emissions (on a volume and mass basis) is coming from natural gas
exploration and production sites located within the City of Fort Worth?
The focus of this task is to characterize hydrocarbon emissions from natural gas point
sources located within the boundaries of the City. We propose to do this through a detailed and
near comprehensive point sources testing plan as explained below. While surveying all 600+
point source locations (wells, well pads, compressor stations, and treatment and disposal
facilities) would be desirable, it may not be feasible given time and resource constraints.
However, our plan (outlined below) attempts to survey, at a minimum, 75% of the existing point
sources. We also understand that the City would like to have this testing conducted in the late
summer to early fall months when elevated ambient temperatures can be expected.
To accomplish this, we propose to deploy two point source teams, each fully equipped
with the necessary sampling instrumentation. Specifically, we will perform the following sub-
tasks:
1) Survey, at a minimum, 75% of the existing natural gas emission point sources with
the FLIR infrared (IR) camera;
12
Professional Services Contract Page 33 of 73
Air Quality Study-Final Work Plan
Eastern Research Group, Inc.
Fort Worth Natural Gas Air Quality Study Final Work Plan
2) Conduct screening with a Thermo Environmental TVA 1000B analyzer on a subset of
point source components at each location following the procedures of EPA Method
21';
3) Perform on-site emission rate testing at each location using the Bacharach High-
Flow® Sampler;
4) Collect samples of emissions at select locations for VOC and Methane analysis in
evacuated SummaTM canisters to determine compound specific emission rates;
5) Calculate point source emissions;
6) Field Data Collection; and
7) Quality assurance.
At the conclusion of this task, we will prepare draft and final reports to the City
summarizing the point source testing results, as well provide all information used to generate
emissions (spreadsheets, video footage, equipment characteristics, etc.).
3.1 Survey Natural Gas Emission Point Sources with the IR Camera
The objective of this sub-task is to survey point source equipment at natural gas facilities.
We will use the IR camera to survey:
Active well pads;
Compressor stations;
Processing facilities;
Tank batteries;
Saltwater evaporation facilities;
Water recycling units; and
Gathering stations under City control.
Natural gas transmission lines will not be included in the point source survey unless
located within the battery limits of any of the above facilities. While the exact number of point
sources within the City is currently unknown until the results of the planning contract are
finished, we are presenting approximate counts in Table 5:

Air Quality Study-Final Work Plan
Eastern Research Group, Inc.
Fort Worth Natural Gas Air Quality Study Final Work Plan
As stated before, ideally we would like to capture all natural gas facilities within the City.
However, this goal may not be feasible due to cost and time constraints. Therefore, we are
proposing to survey, at a minimum, 75% of the natural gas facilities, randomly selected from the
entire population of facilities. The exact number will be determined once the results of the
planning study are completed. We feel that information gathered from a minimum of 75% of the
natural gas facilities will provide a wealth of information in characterizing emissions from these
sources. Additionally, scientifically defensible and statistically robust surrogates can be
developed and applied to the facilities which were not surveyed. To ensure as representative
coverage as possible, the City will be gridded into equal area sections with an alphanumeric
identifier applied to each section. Individual Sector Survey maps of the sources of interest will be
created from the GIS information provided by the City, and assigned to each Point Source
Sampling Team. The two survey teams will work in adjacent sectors to facilitate
communications, to provide each other with equipment and manpower support as necessary, and
for safety reasons.
Equipment surveys will be performed by Level I and Level II Thermographers using
FUR GasFindIR® cameras. An example camera is presented below.

GasFindIR rrn� ra,
All emissions detected with the IR camera will be video recorded. Emission points will
also be photographed with a digital camera to aid with identification. The advantage of using the
IR camera is that it is able to scan large areas rapidly and visually detect emissions (i.e., large
emissions greater than 10,000 ppmv) in real time. It is ideal for sensing emissions from
equipment in natural gas service since it readily responds to methane, the largest constituent of
natural gas, as well as ethane, propane, and butane. Another advantage of the IR camera is that
the operator can effectively use this technology at a distance up to 50 feet from the source of
interest.
While the IR camera is extremely good at detecting large emissions, it is limited in
several important aspects:
It does not reliably detect "minor" emissions (i.e. emissions that are less than
10,000 ppmv).
It cannot quantify an emission's concentration in ppmv.
It can not provide empirical data on the emission's mass release rate—how many
pounds per year are being emitted?
14
Professional Services Contract Page 35 of 73
Air Quality Study-Final Work Plan
Eastern Research Group, Inc.
Fort Worth Natural Gas Air Quality Study Final Work Plan
It cannot speciate the emissions. It is unable to tell, for instance, how much of the
emission is methane, propane, ethane, benzene, or xylene.
The following information will be collected at each site:
Wellpad Name/ID;
Owner/operator information;
Physical location information (address, GPS coordinates, facility boundaries);
Information on activities taking place during the point source testing (i.e., drilling,
fracturing, completion, production, etc.);
Description of equipment at site/digital photograph;
Facility Throughput(cf/d);
Wet gas/dry gas information;
Site operational status; and
Valve, connector and other components counts.
Additionally, the following information will be collected at each site for each IR-detected
emission point:
Timestamp;
Equipment ID/Description;
Equipment Size;
Camera ID/Operator ID;
Detection Distance (feet);
Screening Value (ppm);
Video File Name;
Ambient temperature (°F), wind information, relative humidity (%);barometric
pressure (kPa), and cloud cover (%) using a hand-held device;
Ambient lighting;
IR background; and
Maximum siting distance.
Finally, the following modeling information will be collected from the owner and/or
operator when emissions are detected with the IR camera:
Vents or Stack Information—release height (ft) above ground, gas temperature,
gas velocity (ft/sec), stack diameter;
Fugitive fixed point releases—release height above ground;
Area sources information—release height above ground, geometry, width(ft),
length(ft);
Tanks information—Roof height above ground (ft), Tank diameter (ft); and
Nearby traffic conditions.
If a site has compressor engines, we propose to collect engine operating parameters (e.g.
engine make, model, and size) and contact the equipment manufacturer to obtain emission

factors (e.g., NO,, PM, hazardous air pollutants, etc). In lieu of vendor data, U.S. EPA published
emission factors may be used to estimate emissions.
3.2 Conduct Screening at Point Sources using the TVA
The objectives of this sub-task is to screen all emissions from sources identified by the IR
camera, as well as to screen a subset of components from which no emissions were detected with
the camera. This task will be conducted at each site. Assuming that the points of interest are
accesible, screening will be performed with a Toxic Vapor Analyzer (TVA) 100013 following the
procedures of U.S. EPA Method 21. An example TVA 100013 is presented below.
f
t
f c i J F�3
� ����i�o%iii%%' '/% f✓;fir, � �i
The TVA-100013 is a portable hydrocarbon monitor with a screening range extending
from 0.5 ppmv to 50,000 ppmv. Because it is portable, operators can take measurements as close
to the equipment as possible. However, we do anticipate that at some sites, using this technology
may not be possible due to the locations of the sources of interest.
The analyzer uses a flame ionization detector(FID) to sample and measure gases.
Concentrations in ppmv can be read on both the hand held probe and on the instrument sidepack.
The response of the TVA to different hydrocarbons is determined by the response characteristics
of the flame ionization detector and by the gas species used to calibrate the instrument. The unit
is factory calibrated with methane. Since methane is the largest constituent of natural gas,
continued methane-calibration of the TVA is appropriate for this project. Thus all concentrations
detected by the TVA 100013 will be reported as methane.
Equipment Testing
All emissions that are detected by the IR Camera will be further screened with the TVA
to measure their concentration in parts per million volume (ppmv). Because the camera sees
large emissions (i.e. > 10,000 ppmv), the concentration of some emission points will likely
exceed the upper range of the TVA (50,000 ppmv or 5%) resulting in a possible "flame-out" of
16

the analyzer.In these instances, we will employ a common practice of using a 10:1 dilution
probe to dilute the sample to a concentration level that is able to be surveyed using the TVA (the
sample will be diluted to below 50,000 ppmv).
Components Testing
Because a typical wellpad may contain hundreds to thousands of components, it is not
feasible from a time perspective to test each component. We will attempt to screen as many
components as possible, but given the typical duration of a site visit, we anticipate that, at an
average screening rate of 250 components per hour, a minimum of 10% of the total number of
facility components will be screened using the TVA, including all sources identified by the IR
Camera. Minor-emitting components (those not detected using the IR Camera but detected using
the TVA) will be randomly selected from the following component types: Valves, Connectors,
and Other Components (pumps, compressors, pressure relief devices, open ended lines,
pipelines, etc.).
3.3 Collect Emission Rate Information with the HiFlow Sampler
The objective of this sub-task is to measure emission rates from equipment directly with
the Bacharach HiFlow Sampler. This information is important in accurately estimating emission
rates at each point source being surveyed. The HiFlow Sampler is a portable, intrinsically safe
instrument designed to determine the rate of gas leakage from components in natural gas service.
An example of this equipment is presented below.

HIGH•FLO SAMPLER
A component's leak rate is measured by sampling at a high enough flow rate to ensure
that all of the gas emitted from the component will be captured. The HiFlow Sampler calculates
the resulting leak rate as % concentration per cubic feet/minute by accurately measuring the flow
rate of the sample stream and the natural gas concentration within that stream. Emissions from a
component are drawn into the unit through a flexible 1.5 inch I.D. hose. An assortment of hose-
2 A TVA flame-out can occur when the sample concentration is sufficiently high to prevent sufficient air from
reaching the detector burner assembly. As a result the hydrogen flame is extinguished and the analyzer must be re-
lit.

end attachments are availabe to provide a means of capturing all the gas that is being emitted.
Sample flow rate is measured as the pressure differential developed as it passes through a fixed
orifice and sample concentration, as methane, is measured by an on-board combustible gas
sensor with a range of 0.05% (500 ppm) to 100% gas by volume.
The HiFlow Sampler will be used to test the flow of emissions from sources that have
been identified by the IR Camera. Since each Sampler run only takes 3-8 minutes, this provides
a very quick and economical way to measure emission rates from these sources. The same
constraints applicable to the screening of components with the TVA, will apply to testing with
the HiFlow Sampler. That is, components considered Difficult to Monitor or Unsafe to Monitor,
will not be able to be tested with the HiFlow Sampler. Instead, they will be documented and the
list provided to the City for consideration.
The HiFlow Sampler will also be used to determine emission rates for components
identified through the screening effort with the TVA to have emission concentrations greater
than 500 ppmv.
Minor-Emitting Component Testing
As stated above, we will randomly collect TVA samples from minor-emitting
components. To generate emission rates for these minor-emitting components, we will also us
the HiFlow Sampler to characterize emission rate flows. While one inspector is surveying the
facility with the IR camera, the second inspector will conduct a selective screening of
components with the TVA following EPA Method 21 procedures. The purpose of this screening
will be to identify equipment emissions that are below the detection threshold of the IR camera
(i.e. minor emissions < 10,000 ppmv). Since the cumulative effect of these minor emission
sources can possibly equal or exceed a major source emission, it is important that they be
considered in a facility's overall emission potential.
Two types of"units" will be considered in this case: natural gas facilities in wet
gas service and natural gas facilities in dry gas service. Since components with emission
concentrations of 10,000 ppmv and above (i.e. components with emissions sufficient to
be detected by the IR camera) will have already been selected for emission rate testing,
additional emission rate testing would only need to be conducted in the three categories
below 10,000 ppmv. Since the HiFlow Sampler cannot reliably detect emission rates at
concentrations less than 500 ppmv, we propose to conduct HiFlow Sampler emission rate
testing on components falling within the following two concentration groupings: 500-
1000 ppmv and 1001-10,000 ppmv and to use EPA emission factors for components
with emission concentrations below 500 ppmv.
Table 6 defines the proposed HiFlow Sampler test matrix for components with
screening values between 500— 10,000 ppmv.

The emission rates developed for each of these service-component type combinations
will be used to generate equipment count-service type surrogate factors, which can then be
applied to the enitre natural gas inventory.
The following information will be collected when emission rate measurements are made
using the HiFlow sampler:
Equipment ID/Description;
Equipment Size;
Operator ID;
Pre-Screening Value (ppm);
HiFlow Sampler ID;
HiFlow Sampler Sample ID;
HiFlow Sampler Result (% * cfm); and
Post-Screening Value (ppm).
3.4 Collect Samples of VOC and Methane Using SUMMA Canisters
The objective of this sub-task is to determine compound-specific emission rates by
collecting VOC and methane samples using SUMMA canisters. Although ideal, it is not
economically feasible to collect this data at each site. Therefore, collection of these samples will
be taken at a representative number of point sources, which then can be used as surrogates for the
entire population. An example of a SUMMA canister is presented below.
I
a iu
IJ
f k

SUMMA
Canister
The canister samples will be collected at the exhaust port of the HiFlow Sampler and sent
to TestAmerica laboratories in Austin, Texas for general hydrocarbon analyses (Analytical
Method TO-15), and for methane analyses (Analytical Method D-1946). Information about these
two analytical methods is provided in Appendix A.
Because emission rate data from the HiFlow Sampler is basically expressed as % total
hydrocarbon per cubic foot/minute (i.e., methane response factors), we will be able to use the
20
Professional Services Contract Page 41 of 73
Air Quality Study-Final Work Plan
Eastern Research Group, Inc.
Fort Worth Natural Gas Air Quality Study Final Work Plan
results of the Summa canister analysis to determine the emission rate for individual compounds,
such as benzene, toluene, methane, ethane, propane, butane, etc.
For typical sampling scenarios, it is expected that no more than one canister sample will
need be collected to characterize multiple IR-detected emissions at any one facility. The reason
is that once the emission rate as methane has been measured with the HiFlow Sampler, the same
constituent proportions identified in a single canister sample can be assumed for all emission
sources at that same facility. In other words, if three IR-detected emissions are identified at the
same facility, the emission rate for each will be determined with the HiFlow Sampler but only
one canister sample will be collected and used to calculate speciated emission rates for all three.
Atypical sampling scenarios occur if the speciation profile of additional sources is expected to be
different from the majority of sources. For example, sites with saltwater tanks may have a toxics
speciation profile that is different, thus requiring multiple canister sampling.
Speciated emission rates will be reported in pounds per hour, unless other units are
requested.
The following information will be collected when VOC and methane samples are
collected:
Canister ID#;
Canister Sample Number;
Canister Initial Vacuum(inch-Hg);
Canister Sample Start Time (HH:MM:SEC);
Canister Sample Stop Time (HH:MM:SEC); and
Canister Final Vaccuum(inch-Hg).
In addition to the canisters that will be sent for laboratory analysis, the City is also
interested in collecting additional canister samples, but not analyzing them immediately or at all.
The idea is that if more speciated canister sampling data is needed to enhance the surrogate
profiles, the City can have the option of having these canisters analyzed without having to go
back to a site. For these canisters, we will follow the same procedures in collecting the sample
mentioned above.
3.5 Calculate Point Source Emissions
The objective of this sub-task is to calculate point source emissions. We will generate
emission rates for each unit/component surveyed using standard equations. For example, if the
HiFlow sampler detects a 5% methane emission at a flow rate of 8 cubic feet/minute, and an
analysis of a canister sample collected at the exhaust of the HiFlow sampler yields a 50 ppmv
benzene concentration, then the benzene emission rate can be calculated as:
X AI W
E.R. _ 24.45 x FR x 7.7E-7
21
Professional Services Contract Page 42 of 73
Air Quality Study-Final Work Plan
Eastern Research Group, Inc.
Fort Worth Natural Gas Air Quality Study Final Work Plan
Where:
E.R. = Emission Rate (lb/hour)
C = Concentration (ppmv)
MW = Molecular Weight
24.45 = Molar Volume @ 25°C and 1 atmosphere
FR = Flow Rate (ft3/min)
7.7 E-7 = Units Conversion Factor.
In the above example, a 50 ppmv benzene canister concentration measured at a flow rate
of 8 ft3/min would correspond to a benzene emission rate of 9.84 E-4 lb/hour, using 78.11 g/mol
as the molecular weight of benzene.
Emission points < 500 ppmv are outside the range of the HiFlow Sampler, but can be
characterized using EPA screening correlations. Using these correlations, we can determine
emission rates for components with concentrations below this threshold. Alternatively, if the City
desires to quantify emission rates below 500 ppmv using the site-specific test data, the
blow-through bagging method as described in EPA's Protocol for Equipment Leak Emission
Estimates3 can be performed as an option. The speciation profiles developed from the canister
data will still be applied to these low concentration data.
Based upon previous experience at other natural gas sites, it is expected that a sufficient
number of minor emitting components in both dry gas and in wet gas service will be avalable for
testing to provide an good understanding of the contribution of smaller emissions (<10,000
ppmv) to a facility's overall emission profile. This information will also be valuable in
determining emission increases due to future buildup.
3.6 Field Data Collection
Due to the size and nature of this study, it will be important that all data is collected
during each site visit, and archived properly. Site specific information will be collected at each
point source location and recorded digitally on Archer Field PCs. An example field PC is
presented below.

This information will include site characterization data, IR-detected emission data,
emission rate testing data and information necessary to the modeling effort. Pre-formatted
electronic datasheets stored on the Archer Field PCs will be used to record site information and
monitoring results. At the conclusion of each day's point source testing, data stored on the Field
PCs will be downloaded to spreadsheets and backed up on dedicated hard drives.
All emissions detected with the IR Camera will be video recorded and saved as digital
video files. These video files will subsequently be processed using Windows Movie MakerTM
software. Processing of raw video files will consist of adding a title slide with timestamp and
descriptive information followed by a digital photograph of the emission source. Some editing of
the IR Camera video may be performed to improve quality of presentation. The completed video
recording will then be saved with a descriptive filename as a Windows Media Video file
(*.wmv).
3.7 Quality Assurance Procedures and Equipment
The objective of this sub-task is to ensure that all procdures are followed and all testing
equipment is working properly. Below, we list the responsibilities of the quality
assurance/quality control(QA/QC) reviewer and equipment calibration procedures.
QA/QC Reviewer
Mr. Arthur Bedrosian will serve as Quality Control reviewer of the point-source survey
effort. With nearly 40 years of experience, Mr. Bedrosian has worked on numerous air quality
projects within the state of Texas, and has keen insight and sensitivity to all facets of point
sources testing. Mr. Bedrosian's responsibilities will include the following:
0 Oversight of the survey program for conformance with this work plan, any
relevent standards and instructions;
0 Checking identification and completeness of project documentation;
23
Professional Services Contract Page 44 of 73
Air Quality Study-Final Work Plan
Eastern Research Group, Inc.
Fort Worth Natural Gas Air Quality Study Final Work Plan
Checking for appropriate use of forms, logs or formats;
Ensuring that all equipment is properly referenced and calibrated;
Checking that equipment meets specifications; and
Random inspection of field activities to ensure they are being performed in
accordance with the procedures listed in this project plan and that instrument
calibration records are complete and indicate that instruments are in a state of
control during use.
Mr. Bedrosian will report any quality control concerns to the Point Source Project
Manager, Mr. David Ranum who will be responsible for addressing them.
Instrument Calibration
Individual quality assurance items for each piece of equipment include, but are not
limited to the following:
1. IR Camera Daily Demonstration. The following procedures will be implemented each
day prior to using each IR camera for emission surveying:
a. The camera will be turned on and allowed to cool down (cool down time is
approximately 6 minutes);
b. Following cool down, the camera will be taken outside and allowed several
minutes to equilibrate to ambient conditions;
c. After the equilibration period, several non-uniformity corrections will be
performed; and
d. The camera daily demo (daily demonstration) will then be conducted. This
demonstration will be performed at two mass flow rates: a low rate equivalent to
approximately 5 grams propane/hour and a high rate equivalent to approximately
25 grams propane/hour, with a video recording made of each result. The distance
from which the camera operator is able to see the propane plume (i.e., the sighting
distance) will be recorded for each mass flow rate together with ambient
temperature, wind speed, relative humidity, barometric pressure, cloud cover, and
ambient lighting conditions.
2. TVA 100013 Calibration and Drift Checks. The TVA 1000BTM analyzers will be
calibrated daily prior to field use with certified±2% accurate calibration gases
equipped with demand-flow regulators. Both instruments will also be performance
tested(response time, precision, flow rate) at the start of the testing period. Four gas
standard concentrations will be used for the daily calibrations: 0, 500, 1,000, and
10,000 ppmv methane-in-air. Drift checks will be performed using the 500-ppmv
standard, at mid-day and at end-of-day. Calibration and drift check acceptance criteria
will be±10% of each calibration gas certified concentration. Any responses outside
the acceptance criteria will require either re-calibration or trouble shooting and repair
of the analyzer.
3. HiFlow Sampler Calibration. Both HiFlow Samplers will be calibrated each day prior
to use. For calibration of the background sensor, a 2.5% methane standard will be
24

Fort Worth Natural Gas Air Quality Study Final Work Plan
used. To calibrate the Gas Sample sensor, a 100% methane standard will be used.
Both gas standards will be equipped with Demand Flow Regulators.
4. Canister Sample Collection QC Procedures. The vacuum of each canister will be
checked and documented prior to sampling. Canisters with a vacuum of< 25 in.
mercury(Hg) will not be used. A residual vacuum of 5 -10 in. Hg will be left in the
canister following sample collection. This value will be documented. Appropriate
chain-of-custody procedures will be followed for all canister samples. This means
keeping an accurate written record to track the possession, handling, and location of
the canisters from collection through analysis. Canisters in possession of the point
source survey team will be kept in a secure area with access restricted to authorized
personnel only. The following chain-of-custody guidelines will be observed:
a. Only persons associated with the project will be allowed to handle the canisters.
b. Strict documentation of the transfer of canisters and data from person to person
will be kept on chain-of-custody forms.
c. Written canister documentation will always be legible and with permanent ink.
d. Canister serial numbers will be recorded on the chain of custody documentation.
While Field, Trip and Ambient blanks are customary in ambient air canister sampling
they are less of a consideration in point source sampling due to the high
concentrations involved. No canister blanks are planned for the point source sampling
effort. Field duplicates are second samples collected in the field simultaneously or
near-simultaneously with the primary sample at the same location. The results of the
duplicate sample may be compared with the primary sample to provide information
on consistency and reproducibility of field sampling procedures. Field duplicates will
be collected at a 5%rate (i.e. 1 duplicate per 20 canister samples).
5. Analytical QC Procedures. Analytical QC procedures will include the following:
a. Defining in-house control limits for surrogates, matrix spikes and laboratory
control samples.
b. Batch method blank analyses.
c. Analysis of Quality Control Samples.
d. Canister blank checks.
e. Laboratory control sample and control sample duplicates.
f. Sample duplicates.
g. Surrogate sample analyses.
h. Internal standards analyses.
i. Instrument performance checks.
3.8 Project Safety
Project safety is important to the City, to the Contractor, and especially to the point
source team members. A project Safety & Health plan will be drafted specific to this project.
Each project team will be required:
25
Professional Services Contract Page 46 of 73
Air Quality Study-Final Work Plan

Fort Worth Natural Gas Air Quality Study Final Work Plan
a. To keep with them a signed copy of the project safety plan.
b. To hold daily safety toolbox meetings to review specific project hazards either
encountered or anticipated.
c. To have readily available an emergency first aid kit.
d. To have all required PPE as specified in the project safety plan.
3.9 Point Source Testing Costs
The cost estimate to complete this task is $246,477. Details are provided in Table 8.
4.0 TASK 4-AIR DISPERSION MODELING
0 What effect do emissions from natural gas exploration and production activities have
on ambient air quality at the fenceline?
0 Are the City's setbacks for wells, tanks, and compressors adequate to protect public
health?
Using the point source emissions data obtained under Task 3, air dispersion modeling
will be performed to determine the effect that natural exploration and production activities have
on ambient air quality. Established air quality models will be used to determine pollutant
concentrations at facility fencelines, as well as at distances required under the City's setback
provisions contained in Ordinance 18449-02-2009. The data obtained as a result of this task will
compliment the data determined through the ambient air monitoring network under Task 2, and
collectively, these tasks will serve to answer the two questions above.
4.1 Model Selection and Scenarios
ERG has selected the AMS/EPA Regulatory Model(AERMOD) for use in determining
impacts from sources of interest in this study. We believe AERMOD is the most appropriate
model to implement based on the following reasons:
1. AERMOD is the U.S. EPA preferred air dispersion model for near-field (Appendix W
to 40 CFR Part 51, Guideline on Air Quality Models,
http://www.epa.gov/ttn/scram/guidance/ ug ide/appw 05.pdf, Page 68253);
2. AERMOD is widely accepted and used in the scientific and regulatory community;
3. The study domain falls within the distance limits of AERMOD (50 km or -30 miles);
4. AERMOD supports multiple sources types (vents, stacks, area sources for piping);
5. AERMOD needs only a single meteorological station, along with upper air data to
execute, unlike grid models; and
6. Special meteorological circumstances are not at issue in this case (complex wind
flows, stagnation, complex terrain); therefore, alternate models, such as CALPUFF,
are unnecessary.
ERG proposes local modeling of a limited number of proposed sites spread throughout
the city. Although several areas of the city are affected by the industry, it may be of interest to
the City to intensely study a handful of sites, representing operations across the various phases of
26
Professional Services Contract Page 47 of 73
Air Quality Study-Final Work Plan
Eastern Research Group, Inc.
Fort Worth Natural Gas Air Quality Study Final Work Plan
the gas drilling and production cycle. In consultation with the City, ERG will select sites for
more detailed modeling study. For example, we might consider a simple wellpad, a more
complex wellpad with lift engines and/or a dehydrator, a gas gathering station or compressor
station, and a site affected by both a wellpad and a compressor station. Each analysis will include
analysis of impacts at facility property lines, at setback distances proscribed by the city, and at
local sensitive receptors (such as nearby parks, schools and homes). This analysis will include
our estimates of actual emissions as determined through source testing, downwash effects (if
applicable), locally collected meteorological data, and detailed land use analysis.
4.2 Model Inputs
In the case of individual site modeling, ERG staff will review facility plot plans and
aerial photography to identify property boundaries and fencelines, and uniquely identify all
emissions sources and downwash structures of interest. For all modeling performed, sources will
be correctly classified as either point, volume, or in some cases, area. Sources will also be
located in an appropriate fashion, in an effort to reflect where on the property emissions actually
occur. Source classification and placement will conform to TCEQ guidance; if there is any
uncertainty as to how a particular source should be modeled, adequate justification will be
clearly presented.
Source Parameters
The modeling submittal and electronic files will include a listing of all necessary source
parameters input to the model. These include emission rates, UTM coordinates, base elevation,
source height, stack exit velocity and temperature, and source dimensions, as applicable to each
source type. This data will be obtained at the time of the point source testing, through
development of emission factors under Task 6, or through operator interviews. In addition,
locations, dimensions, and heights of structures on the property that could contribute to building
downwash will be clearly presented. Effects of building downwash will be determined by use of
the PRIME processor.
If sources with similar parameters are combined into one source to reduce model
calculation time,justification will be provided. Effective plume heights for volume sources, if
provided, will be calculated appropriately, and volume sources dimensions will be divided by a
factor of 2.15 per EPA guidance. "Pseudo-point" sources (rain capped or horizontal stacks, for
example) will be modeled with an exit velocity of 0.1 m/s. Area sources, if modeled, will
maintain an aspect ratio of no greater than 10-to-1, and no such sources will extend off property.
Emission Rates
Actual emission rates will be derived from on-site testing, or based on information
provided by site owners, as appropriate. Pollutants of interest include VOCs and HAPs,
including benzene and formaldehyde; other pollutants may be modeled as well, if future
consultation with the city dictates.

Fort Worth Natural Gas Air Quality Study Final Work Plan
Meteorological Data
Meteorological data is collected at several airports and sampling stations in and around
the city, and is publically available through the NOAA and TCEQ. We anticipate that annual
meteorological data collected at the weather station closest to the modeled facility will be used as
a basis for our analysis, subject to availability and proper quality control. If not,justification for
use of an alternate station will be presented. A description of the methodology and software used
to process the data will also be presented. Some meteorological data used for this analysis may
initially include pre-processed and quality checked surface and upper air data for the Fort Worth
area provided by TCEQ, which provides a number of data sets to choose from.
In all cases, the anemometer height, station identifier, and calendar year of the data will
be provided and input to the model. The AERMET meteorological pre-processor will be used to
prepare the data for input to AERMOD, as necessary.
Receptors
The receptor grids developed for individual sites will consist of both appropriate
fenceline receptor spacing (likely 25-50 meters), as determined by the area of the facility, and
downwind receptor spacing. Maximally impacted receptors should be located in spacing of no
greater than 100 meters. ERG expects that most receptor grid spacing will increase as receptors
are located further from the facility, out to distances between 5 and 10 km, but the receptor
spacing must still be dense enough to identify any maxima and develop accurate concentration
isopleths. Receptors will include terrain heights derived from USGS DEM information and
applied using the AERMAP terrain processor. Sensitive receptors, including individual homes,
schools, parks, and other area of interest may be modeled in consultation with the city.
4.3 Model Outputs
As part of the submitted modeling analysis, summaries of model outputs will be clearly
presented. Annual average, maximum hourly, and other applicable short-term averaging period
concentrations for the applicable public health evaluation threshold (such as TCEQ's ESL and
AQMV levels) values will be reported. Summary plots of the modeled receptor grid, along with
pollutant isopleths, will be included as well.
4.4 Modeling Hours and Costs
Modeling of specific sites of interest will require approximately 75 hours per site, but
these costs will vary with the number of sources, receptors, and pollutants modeled. The cost
estimate for this task is $39,230, based on modeling 3 single site scenarios and one combined site
scenario as discussed in Section 4.1. Details on the cost breakdown are provided in Table 8.
5.0 TASK 5— COMMUNICATION AND OUTREACH
Outreach is needed to build trust within the community and to ensure residents that this
project will meet the City's objectives, address the concerns of the citizens of Fort Worth, and be
28
Professional Services Contract Page 49 of 73
Air Quality Study-Final Work Plan
Eastern Research Group, Inc.
Fort Worth Natural Gas Air Quality Study Final Work Plan
conducted in a scientifically defensible fashion. Under a separate contract (Fort Worth Natural
Gas Air Quality Planning Study), ERG will provide the City with a memo delineating options
and recommendations for communication and outreach activities that will achieve these goals.
ERG will work closely with the City to discuss the options and recommendations presented in
the memo before coming to an agreement as to how to proceed with this task.
Under this task, we will then develop a draft communication and outreach plan for
conveying the goals, progress, and results of this study to the citizens of Fort Worth. Once the
plan has been reviewed and finalized, we will implement the communication and outreach
activities accordingly.
Note: Our cost estimate for this task includes costs for 7 1-day trips for project staff to
provide project updates to the City, to the public, or to attend other meetings or conferences as
requested by the City. Additional funds have been set aside for this task to develop and
implement the communication and outreach plan. For purposes of providing an estimate for this
work plan, the costs for this task are $45,254. However, until the full scope of this effort has
been agreed upon with the City, a final cost estimate for this task cannot be determined.
6.0 TASK 6—FULL BUILD-OUT ESTIMATES
Over the last five years, there has been a dramatic increase in natural gas exploration and
production activities in the Barnett Shale, and in the City of Fort Worth itself. This increase has
led to concerns by the citizens of Fort Worth that their quality of life is being impacted by
deteriorating air quality due to these activities. While Tasks 1 through 5 focus on the current air
quality as contributed to by the existing natural gas exploration and production sources, the
expansion of the natural gas industry within the City is expected to continue into the future.
Under this task, the ERG team will develop point source emission factors using the data
collected under Task 3, develop growth estimates to project the number of point sources
anticipated to exist within the City under "full build—out" conditions, and use these data to
develop a city-wide emissions inventory. In this context, "full build-out" means the point at
which the natural gas exploration and production infrastructure has been completed within the
City(i.e. there will be no more wells drilled).
6.1 Point Source Emission Factor Development
Using the results of the point source testing task (Task 3), the ERG team will develop
average emission factors for the following emission units:
Wells
Well pads
Lift and line compressor engines
Equipment leaks
Storage tanks
Dehydrators
Pipelines
29
Professional Services Contract Page 50 of 73
Air Quality Study-Final Work Plan
Eastern Research Group, Inc.
Fort Worth Natural Gas Air Quality Study Final Work Plan
The final sub-categorization of the emission units included in the emission factor
development task will be determined in consultation with the City, considering the measured
variability in emission rates for each unit type (from Task 3) and the availability of process data
on which to base the emission factor(from this task). Depending on availability of data, emission
factors may be developed on a temporal basis (pound per hour or pound per day) or an activity
basis (pound per thousand cubic feet of gas produced). Additionally, operator data will be
collected on pre-production activities (drilling, fracturing, completion) to estimate emissions
from mobile sources (PM generated by truck traffic) and from temporary engines used on-site for
drilling, auxiliary power, and fracturing operations (PM and NOx).
6.2 Growth Estimate Development
Any projection of current emissions levels to future emissions levels will need to take
into account both the total number of emission sites (wells, well pads, treatment and processing
sites) as well as total natural gas production levels. At some point, production of natural gas
within the City will peak, and this will likely occur prior to conclusion of full build-out(the time
at which the last well is completed). An evaluation will be made to determine the point at which
maximum emissions are likely to occur.
The data needed to conduct this evaluation will be obtained under this task from available
resources such as the U.S. Department of Energy, Energy Information Administration (EIA),
from drilling and production projections from trade groups and commercial vendors, or through
other available oil and gas activity projection resources such as Baker Hughes Rig Counts.
Additionally, surveys of the owners and operators can be used to augment future activity
estimates under full build-out conditions.
6.3 Emissions Estimates under Full Build-Out Conditions
Final emission estimates from natural gas exploration and production that are expected to
occur under full build-out conditions will be developed using the emission factors developed
under Task 6.1, and the growth estimates developed under Task 6.2. All assumptions and
calculations used to prepare the full build-out inventory will be documented and reviewed with
the City prior to finalization.
6.4 Full Build-Out Evaluation Hours and Costs
The cost estimate for this task is $10,900, which assumes that baseline emissions will be
linearly extrapolated to full build-out emissions based on the maximum projected natural gas
production rate within the City at some point in the future as compared to current production. A
more refined analysis, such as attempting to provide geo-specificity to the full build-out
inventory, would require additional resources. Details on the cost breakdown are provided in
Table 8.

7.0 TASK 7—FINAL REPORT
An all-inclusive final report presenting the findings of this study will be prepared under
Task 7. A proposed outline for the final report, including a brief description of the content of
each section, is provided below.
Section I -Ambient Monitoring Methodology and Results
This section will present a summary of the findings of the ambient air monitoring
network, with detailed analytical results for each monitoring sample presented in an Appendix.
The discussion will provide details on network development, network implementation, the
methodology used to collect and analyze the samples, the quality assurance/control control
(QA/QC) results, and any changes made to the ambient network monitoring design as the project
progressed.
Section 2 - Point Source Testing Methodology and Results
This section will present a summary of the findings of the point source testing task (Task
3), with detailed analytical results for each point source presented in an Appendix. The
discussion will provide details on point source identification, the sampling approach, the
methodology used to collect and analyze the samples, the QA/QC results, and any changes made
to the point source testing plan as the project progressed.
Section 3 - Dispersion Modeling Methodology and Results
This section will present a summary of the dispersion modeling effort, including model
input parameters (stack height, emissions rates, meteorological data), model methodology
development, and modeling results.
Section 4 - Public Health Evaluation
Are the City's setbacks for wells, tanks, and compressors adequate to protect public
health?
This section of the report will evaluate public health impacts associated with natural gas
exploration and production activities to provide context for the question about the adequacy of
setbacks. The public health evaluation will integrate findings from numerous data sources. Much
of the focus will be on pollutant concentrations determined under Tasks 2 (Ambient Air
Monitoring) and 3 (Dispersion Modeling), and these will be compared to relevant state, federal,
and international health guidelines. Consideration will be given to both cancer and non-cancer
health effects and evaluation of both acute and chronic exposure durations.
More detailed evaluations will be offered for pollutants found to exceed their
corresponding health guidelines. These evaluations will summarize information on the health
effects of the pollutant of concern, primarily by reviewing the relevant toxicological and
epidemiological literature. The detailed evaluations will also consider any unique health risks
31

experienced by susceptible populations (e.g., children, the elderly, and persons with pre-existing
health conditions). Uncertainties in the public health evaluation will also be identified and
discussed, and some discussion will be included on the potential public health implications
regarding simultaneous exposures to mixtures of multiple pollutants.
Additional context will be provided by comparing measurements made during this
program to those made during other studies that have examined air quality impacts of Fort
Worth's oil and gas exploration activity. The measurements will also be compared to levels
typically measured in similar urban and suburban settings, for further perspective.
Section 5 -Regulatory Assessment
Do the sites comply with applicable regulatory limits?
Upon completion of the point source testing task, facility-level emission estimates
developed for wells, well pads, gathering stations, treatment and processing plants, and disposal
facilities will be evaluated against various regulatory thresholds and standards. Regulatory
standards to be considered include TCEQ's permit-by-rule and standard permit thresholds, Title
V Operating Permit thresholds, New Source Review (NSR) thresholds for Prevention of
Significant Deterioration (PSD) and Nonattainment NSR, and EPA's NESHAP and Maximum
Achievable Control Technology(MACT) standards.
Section 6 - Full Build-Out Estimates
This section of the report will present a summary of the results of Task 6, including the
point source emission factors developed under Task 3, and an assessment of both baseline
emissions (current conditions) and emissions at full build-out.
Section 7- Conclusions and Recommendations
The final section of the report will present our conclusions as to the findings of the study,
as well as recommendations for future considerations.
The cost estimate for this task is $41,092, with much of this effort dedicated to the public
health evaluation in Section 4 (approximately $18,000). Details on the cost breakdown are
provided in Table 8.

10.0 OPTIONAL STUDIES
10.1 Ambient Air Monitoring (Optional Long-term Study)
This task was not originally listed in the Request for Qualifications, but the City
expressed interest in potentially extending the short-term monitoring study to at least one-year to
obtain true long-term(annual) monitoring data. After evaluating initial short-term results, it may
become evident that some, if not all the short-term sites should be used for long-term monitoring.
We envision that once long-term monitoring begins, the sampling schedule would convert from
once every three days to once every six days. Thus, in one year, approximately 70 samples may
be collected at a site, which is more than sufficient in developing an annual average suitable for
long-term exposure comparisons.
Similar to the short-term study, we propose sampling for VOCs, SNMOC, and methane.
Carbonyls would not be collected under this scheme unless the initial screening showed results
indicating the need for a long-term evaluation. It is strongly recommended that long-term
monitoring begin at the end of the short-term monitoring without delay, such that a years worth
of samples can be collected by mid-August 2011. Table 10 presents the long-term number of
samples needed to accomplish this task. Note that ERG'S cost estimate does not include the costs
for performing this task.

(1-in-6 days)
Overall Total Samples = 276
10.2 Ambient Air Monitoring (Optional Well Site Life-cycle Study)
This task was not originally listed in the Request for Qualifications, but the City
expressed interest in a specialized short-term study evaluating activities during the "lifecycle" of
a production well. The lifecycle includes: pre-bit activities, drilling and fracturing activities; well
completion activities; and production activities. The City estimates that these activities typically
occur during a 6-month period. To accomplish this task, we envision the following schedule:
1) pre-bit activities: one site, sampling once every 6 days
2) drilling and fracturing activities: five sites, once every three days
3) well completion activities: five sites, once every three days
4) production activities: one site, sampling every 6 days
Monitoring sites would be situated around the fenceline surrounding the wellpad. Additionally,
we recommend installing an anemometer at the fenceline to capture the behavior of the wind
36

Air Quality Study-Final Work Plan

Fort Worth Natural Gas Air Quality Study Final Work Plan
during this study. Finally, we envision sampling for the same suite of pollutants as the long-term
study(VOCs, SNMOC, and methane). Note that ERG's cost estimate does not include the costs
for performing this task.
10.3 Ambient Air Quality Impact of Full Build-Out Conditions (Optional)
The impact on ambient air quality due to full build-out of natural gas exploration and
production would be determined under this task using air quality modeling. Note that ERG's cost
estimate does not include the costs for performing this task; however, a brief discussion of how
this task could be carried out is provided, along with identification of some of the issues involved
in this type of analysis.
While it is expected that the concentration of pollutants such as benzene in the ambient
air due to natural gas exploration and production would increase under full build-out conditions
on a city-wide basis, impacts to an individual street or residence are more likely to be related to
their proximity to an individual source (e.g., well pad) rather than to the total number of sources
within the City limits.
Given the relative magnitude of emissions from all source types (i.e., point sources, area
sources, mobile sources), changes in air quality in the City due to other sources (especially motor
vehicles) would most likely have a much greater impact on predicted ambient air concentrations
of a specific HAP (e.g., benzene) than would changes in air quality due specifically to natural
gas exploration and development activities. Additionally, any prediction of future air quality
would need to take into account changes in state and federal air quality rules. Examples of these
types of considerations include:
Changes in traffic patterns and population growth
Proposed revisions to TCEQ rules such as the Permit by Rule for Oil and Gas
Production Sites (106.352)
Additions or changes to the U.S. EPA's National Emissions Standards for
Hazardous Air Pollutants (NESHAP) for oil and gas sources
Although these considerations would affect the City's air quality in the future, it is
possible to develop an estimate of the impact that full build-out conditions would have on the
City's air quality. ERG proposes an overall, city-wide modeling analysis conducted in
"regulatory" mode, similar to what industrial facilities do for permits. In this case, we would
model maximum emissions (based on the results of the point source testing, supplemented with
permitted emission rates if necessary) for selected pollutants as determined under Task 6.3, using
TCEQ model-ready meteorological data. Note that this is not a "real-world" analysis, but rather
would be intended to provide an estimate of what the maximum impacts could potentially be.
The downside of this approach is the modeling analysis will most likely overestimate impacts,
due to the conservative modeling assumptions, and due to the lack of geo-specificity of the
locations of the sites at full build-out. However, if conservative results obtained using worst-case
assumptions are below concentrations of concern, a large degree of confidence is achieved that
the public would not be subject to adverse air quality due to full build-out of natural gas
exploration and production in the City.

August 6, 2010
The purpose of this addendum is to acknowledge and reaffirm the requirements of the Scope of
Services in the Request For Qualifications and Addendum 42, specifically related to point source
testing during well completion activities. It was always our intention to conduct point sources
testing for these types of activities during the preparation of our Qualifications Package, the
Qualifications Interview with the Air Quality Committee on June 30, 2010, the kickoff meeting
with the City after selection, throughout the negotiations and discussions with the City, and
during the development of the Work Plans for Contract 41 and Contract 42. We felt like we
have acknowledged our understanding of this important natural gas activity source, as we made
revisions in our Work Plan for Contract 42 to address this issue. The ERG Team is committed to
performing point source testing for one or more well completions, including flowback during this
study.
