Air quality permitting
Our air quality permitting service does more than simply obtain permits on time
and within budget. We continually advise our client of the effect of specific
permit conditions or permit changes on the present and future operation of a
facility. This information helps our clients maintain operating flexibility and make
informed business decisions. For instance, emissions trading and facility-wide
"bubbling" are often effective alternatives to expensive environmental controls.
Tetra Tech provides a critical review of options as part of our strategic support
services.
Emission inventories and emission estimating techniques
Our team of professionals has an impressive history in developing air emission
inventories, ranging from small permitting projects for private industry to million-
dollar compliance efforts for the U.S. Department of Defense. We have
developed easy-to-understand emission inventories for compliance with
Prevention of Significant Deterioration (PSD) and nonattainment permitting
regulations, state air quality regulations, and federal Title V and Risk
Management Plan (RMP) regulations. Often, our clients require specific
database software to store, access, and modify emission inventories for
facilities. Tetra Tech has designed many air emission databases for a variety of
industries to make access and maintenance of air emission datasets simple
and efficient.
Dispersion modeling and impact analysis
Tetra Tech has extensive experience in the development and application of air
quality dispersion models for analyzing potential and existing air quality impacts
from air pollution sources, and for demonstrating compliance with ambient air
quality standards. Because dispersion modeling often plays a major role in air
permitting and other air pollution analyses, proper selection and application of
an air quality dispersion model is essential. Tetra Tech's professionals have the
skills and experience necessary to successfully complete the most technically
challenging dispersion modeling applications. We have developed, used, and
evaluated many different dispersion models and understand how to apply
various modeling techniques. Tetra Tech's dispersion modeling services
include modeling analysis for Clean Air Act permitting, risk assessments, air
monitor placement, and ambient impact research.

testing program that used remote sensing equipment to measure emissions
from tens of thousands of vehicles.
Engineering design and evaluation of control technologies
Tetra Tech provides engineering design and control technology evaluation
services to our clients. Tetra Tech's air quality engineers and scientists have
conducted Best Available Control Technology (BACT) and Reasonably
Available Control Technology (RACT) evaluations of various industries located
in attainment and nonattainment areas and have managed performance
guarantee testing for emissions controls on utility boilers. Tetra Tech has also
designed air pollution control devices to treat off-gases from groundwater
treatment systems. For the U.S. Air Force, Tetra Tech evaluated a number of
air pollution control strategies to meet Clean Air Act requirements. Recently,
Tetra Tech designed a thermal oxidation system that treated soil gases
produced by soil vapor extraction systems at high destruction efficiency.
Hazardous waste combustion
Recent changes in hazardous waste combustion unit permitting and testing
policy have required facilities to rely on guidance documents and verbal
direction from the various U.S. Environmental Protection Agency (EPA) regions.
Tetra Tech developed the Hazardous Waste Combustion Unit Permitting
Manual, a 3,500-page document that assembles current hazardous waste
combustion unit regulation, guidance, and policy. As a result, Tetra Tech is one

S ATISFACTION
Tetra Tech uses several methods to evaluate whether our customers are
satisfied with the products and services we deliver. Some of these methods
include frequent and direct communication, analyzing contract performance
evaluations, and developing service quality questionnaires. Described below
are ways in which we use and react to customer feedback.
We believe that direct customer contact by project team members is the most
effective way to obtain customer feedback. Tetra Tech ensures that the
customer feedback we receive is distributed to the staff that can best act on the
information. For example, we currently receive regular performance evaluations
on most of our contracts. Tetra Tech contract managers review this information
to summarize overall trends for the contract; identify project evaluations that are
only satisfactory or below; and single out specific performance factors such as
technical quality, project management, and financial management for
improvement. Feedback is typically presented to all project members during a
meeting of all project teams working on a contract. Project-specific information
is distributed to each team for review and follow-up action.
Tetra Tech’s Navy CLEAN contract was another example of how we used
feedback to increase customer satisfaction. Tetra Tech’s work covered 31
Navy installations and multiple concurrent projects at most installations. We
used a monthly service quality questionnaire to collect feedback from customers
at each installation. Questionnaire results, budgets, costs, schedules, and
quality information were compiled quarterly to produce an internal performance
monitoring brief for each installation. Tetra Tech project teams used the brief to
develop management and technical strategies, action plans, and short- and
long-term goals that were based on customer feedback and that directly
address customer requirements at each installation. This customer-driven
process helps our project teams improve efficiency and effectiveness. The
Navy’s decision to fund an additional $260 million in Tetra Tech services on the
CLEAN II contract indicated that this process is also effective in increasing
customer satisfaction.

recommendations, Ship Creek Energy Center
authorized preparation of an air quality
construction permit application for a natural gas-
fired, combustion turbine cogeneration project to
repower an existing coal-fired power plant in
Anchorage, Alaska, with a 40-MW combined-
cycle combustion turbine. Successfully
negotiated a modeling protocol with ADEC,
conducted dispersion modeling analyses for
compliance with ambient air quality standards
and PSD increments, and prepared a
construction permit application. Negotiations
with the ADEC allowed Ship Creek Energy
Center to avoid a difficult and time-consuming air
quality modeling analysis for SO2 impacts.
Participated in a public hearing and multiple
stakeholder meetings regarding the repowering
project.
Healy Clean Coal Project
Healy, AK
Provided oversight for an environmental
monitoring program for the Alaska Industrial
Development and Export Authority (AIDEA) for
the 50-MW Healy Clean Coal Project (HCCP)
located near the Denali National Park and
Preserve PSD Class I area. Conducted
technical project review and coordination of the
visibility and air quality monitoring programs that
fulfilled the post-construction monitoring
conditions of the PSD Permit. Prepared a minor
permit application for the restart of HCCP as a
separate facility from the existing Healy Power
Plant operated by Golden Valley Electric
Association (GVEA), and conducted dispersion
modeling as a source within an existing source.
Prepared the NPDES permit and fact sheet for
the wastewater discharges from HCCP and the
Healy Power Plant.
Coast Guard Cogeneration Project – Nyman
Power Plant
Kodiak, AK
Evaluated impacts for a Borrower’s
Environmental Report (BER) to support a power
generation study. This document, which is
equivalent to a federal EA, enabled the Rural
Utilities Service to evaluate the environmental
effects of a 5-MW combustion turbine
cogeneration project for Kodiak Electric
Association. Prepared a PSD-avoidance
construction permit application for the Nyman
Power Plant. Conducted dispersion modeling for
compliance with ambient air quality standards
and PSD increments. Gained ADEC’s
acceptance of a non-standard modeling
procedure that allowed a shorter exhaust stack
to be built to achieve compliance with PSD
increments, thereby helping to reduce overall
project costs.
P R O J E C T S U M M A R I E S
T E T R A T E C H
Dillingham Power Plant PSD Permitting
Dillingham, AK
Solved complex historical permitting issues for a
power plant upgrade for Nushagak Electric
Cooperative. Negotiated an agreement with
ADEC that allowed existing power generation
equipment to continue to operate, without
implementing retroactive BACT on aging power
generation equipment, until the useful life of
each unit is depleted. Used consumer rate
increase data to successfully convince ADEC
and EPA that NOx emission control with
Selective Catalytic Reduction was too costly to
be considered BACT. Developed a data set that
met EPA’s and ADEC’s approval, thereby
avoiding costly meteorological monitoring that
would have delayed the project approximately 18
months. Convinced ADEC to agree to a
reasonable construction schedule and to delete
onerous conditions and inapplicable
requirements. Developed the Title V operating
permit for the facility.
Providence Alaska Medical Center
Cogeneration Project.
Anchorage, AK
Supervised the preparation of a Title V operating
permit application for new 4-MW combined-cycle
combustion turbine and 15-MMBtu/hr duct
burner to supply electricity and steam to the
Providence Alaska Medical Center in
Anchorage, Alaska. Conducted an air quality
dispersion modeling analysis for NOx and CO
impacts as part of a stack height design
analysis. The modeling analysis included
sensitive receptors at the hospital and a
demonstration of insignificant project impacts to
the Anchorage CO nonattainment area.
Chena Power Plant Modifications
Fairbanks, AK
Performed an assessment of the permitting
implications of major modifications at a 25-MW
coal-fired power plant for Aurora Energy.
Evaluated the effect that replacement of three
coal-fired boilers with a new, larger coal-fired
boiler would have on air permits. Prepared a
strategy to avoid PSD review of the
modifications. Assisted with the resolution of
ongoing air quality compliance-related issues.
Usibelli Coal Mine, Inc., Emma Creek Project.
Healy, AK
Conducted the air quality segment of the
feasibility and fatal flaw analysis for constructing
a 200-MW net circulating fluidized bed coal-fired
power facility to be located near Healy, Alaska,
UCM. Evaluated the PSD construction permit
and Title V operating permit requirements for the
proposed facility. As part of this evaluation,
reviewed the meteorological data and ambient
air quality data available to the project and made
a pre-construction monitoring determination.
Conducted conservative screening modeling
analyses and predicted impacts that exceed the
PSD increments. As a result of the screening
analysis, made recommendations for refined
modeling that would be expected to result in
impacts that demonstrate compliance with the
PSD increments.

evaluations for 21 oil tank batteries and transfer stations located on the Uintah and Ouray Indian
Reservation in the Uinta Basin of Utah. Reviewed available oil and gas facility records and conducted
site visits to obtain the production equipment specifications needed to complete detailed facility emissions
inventories and compliance audits. In addition, successfully urged U.S. Environmental Protection Agency
(EPA) to rescind the unwarranted PSD construction permit issued for Shenandoah’s Wonsits Valley Unit
No. 6 oil and gas production facility that EPA had improperly classified as a PSD major source. Also
persuaded EPA to withdraw its directive that Shenandoah obtain a federal Title V operating permit for that
same Shenandoah facility. Presented a position statement to EPA to explain why the Wonsits Valley
Compressor Station and the Red Wash 24B Gas Plant that extracted natural gas liquids from that
compressor station’s gas were not classified as a single source. Successfully halted EPA’s attempt to
aggregate the two facilities into a single PSD major source, and convinced EPA to treat the facilities as
separate minor sources for air permitting purposes.

Trident Seafoods Corporation, Akutan Seafood Processing Facility Permitting. Prepared an air
quality construction permit application to resolve potential air quality compliance and operating problems
encountered at a seafood processing facility in Akutan, Alaska. Developed a state-approved modeling
protocol that encompassed Trident Seafoods’ various operating scenarios and allowed the facility to avoid
PSD review. When it looked as though Trident Seafoods would be constrained by impacts predicted with
typical dispersion modeling techniques for very steep, complex terrain receptors, developed a
methodology that used EPA’s CTSCREEN model to refine impacts and demonstrate compliance with
PSD increments for SO2. As a result of modeling and permitting efforts, Trident Seafood’s operating
costs were lowered by avoiding the ongoing expense of lower sulfur fuel and the increased construction
costs of substantially taller exhaust stacks.
Trident Seafoods Corporation, Sand Point Seafood Processing Facility Permitting. Conducted
dispersion modeling and prepared a construction permit application for a seafood processing facility
located in Sand Point, Alaska. Because there were no hourly meteorological data available to support the
NOx and SO2 modeling analysis for the permit application, the state offered two objectionable options for
modeling emissions: either delay the project and collect 1 year of on-site meteorological data, or
drastically reduce facility operations. Subsequently, Mr. Gibbons developed an alternative modeling
protocol that utilized EPA’s SCREEN3 model and the ISC-PRIME model to demonstrate compliance with
PSD increments and air quality standards. Mr. Gibbons also utilized historic emission source data for
modeling of baseline sources to effectively expand the available PSD increment for the project.
Trident Seafoods Corporation, St. Paul Plant Construction Permitting. Prepared the air quality
construction permit application for the St. Paul Plant seafood processing facility in St. Paul, Alaska, to
resolve a potential regional air quality problem in an Alaska SO2 Special Protection Area. Supervised the
development of the regional emission inventory and air quality dispersion modeling to support the permit
application. The project successfully coordinated permit approvals for several competing industrial
facilities in St. Paul to the satisfaction of all involved. The modeling analyses for the St. Paul Plant
included evaluation of multiple operating scenarios to demonstrate compliance with ambient air quality
standards and PSD increments.

project successfully coordinated permit approvals for several competing industrial facilities in St. Paul to
the satisfaction of all involved.
Uranium One, Mill and Mine Permitting. Managed the preparation of Utah Notice of Intent (NOI)
documentation in support of approval orders for the Shootaring Mill, Ticaboo Townsite generating station,
and Frank M and Velvet Mines located in southern Utah. Conducted site visits to develop the source
inventory and acquire information needed for dispersion modeling analyses.
Usibelli Coal Mine, Inc., Emma Creek Project. Conducted the air quality segment of the feasibility and
fatal flaw analysis for constructing a 200-MW net circulating fluidized bed coal-fired power facility to be
located near Healy, Alaska, UCM. Evaluated the PSD construction permit and Title V operating permit
requirements for the proposed facility. As part of this evaluation, Mr. Gibbons reviewed the
meteorological data and ambient air quality data available to the project and made a pre-construction
monitoring determination. He conducted conservative screening modeling analyses and predicted
impacts that exceed the PSD increments. As a result of the screening analysis, Mr. Gibbons made
recommendations for refined modeling that would be expected to result in impacts that demonstrate
compliance with the PSD increments.
Usibelli Coal Mine, Inc., Mine Expansion Feasibility Project. Supervised the feasibility analysis of
constructing and operating a coal processing/beneficiation plant to improve combustion and export

efforts to demonstrate compliance with ambient air quality standards in support of a PSD permit
application for a seafood processing facility located in Dutch Harbor, Alaska. Provided technical
assistance in evaluating PSD and PSD-avoidance permitting options, some of which could have had the
potential for costly emission control technologies and ambient air quality and meteorological monitoring
requirements. Mr. Gibbons also successfully coordinated the preparation of the PSD permit application,
which was unsuccessfully attempted by Westward’s previous contractor.
Wilexco, Inc., National Energy Plant One. Led the air quality team in permitting efforts to demonstrate
compliance with ambient air quality standards and emission limits in support of a PSD construction permit
application for a 100-MW waste tire-fueled power plant located in El Paso County, Colorado. An integral
part of the permitting process involved modeling for compliance with ambient air quality standards, PSD
increments, and visibility standards in Class I PSD areas. PSD increments, and visibility standards in
Class I PSD areas. Provided oversight for the BACT analysis of the moving-grate steam boilers that will

and dispersion model and calculating the risk associated with potential accidental releases from the
proposed pipeline. The release and dispersion model used a set of equations that Mr. Hammer
transferred into FORTRAN code and further refined as part of this Tetra Tech project. Risk calculations
were completed using a program also originally developed and written previously by Mr. Hammer and
slightly modified by Tetra Tech for this project.

ECDC Environmental, Municipal Landfill Facility Air Permitting. Mr. Hammer conducted the
regulatory and technical requirements for additional permitting requirements involving the installation of a
railcar rotary dump. This work involved extensive work with ECDC legal counsel and the State of Utah to
establish applicable requirements and emissions estimation and impact analysis techniques. Permitting
of this facility was required due to the installation of enclosures and controls on the railcar rotary dump
and associated propane fired railcar heating operations. Technical work involved the estimation of
controlled and uncontrolled criteria pollutant emissions.
ECDC Environmental, Emission Inventories. Mr. Hammer has assisted ECDC in preparing annual
emission inventories that are reported to the State of Utah. The emission reports have included the
reporting of standard criteria pollutant emissions, hazardous air pollutants (HAPs), as well as the
preparation of no-methane organic compound (NMOC) emission inventories. The preparation of NMOC
emission estimates involved the use of landfill specific emission estimation software and the comparison
of NMOC emission estimate levels to regulatory triggers that would require collection and control system
design.
ECDC Environmental, Landfill Gas Testing. Mr. Hammer planned and coordinated the testing of
NMOC emission rates from the ECDC landfill to meet the Tier 2 testing requirements from New Source
Performance Standard (NSPS) Subpart WWW, which the landfill is subject to. This testing was
necessary since the estimate of landfill NMOC emissions using Tier 1 techniques resulted in annual
NMOC emission of more than 50 megagrams per year (mg/yr). As a result of the Tier 2 testing, the
annual emission inventory of NMOC emissions was reduced to levels below the 50 mg/yr trigger for
collection and control system design plan requirements, thus avoiding the requirement to install collection
and control systems for several years.
ECDC Environmental, Title V Permit Application. Mr. Hammer coordinated and worked on the
preparation of the Title V application for the ECDC landfill. He developed the techniques used to prepare
and coordinate the extensive data required for the Title V application. With his oversight and direction, all

cement facility that allowed a production increase but did not trigger federal prevention of significant
deterioration (PSD) requirements.
Environmental Reconnaissance, Iron Carbide Manufacturer. Developed a complex, multi-task
environmental reconnaissance strategy to uncover any fatal environmental flaws associated with the
development of an iron carbide manufacturing facility near the Mississippi river. Federal, state and local
requirements for air, water, waste and land were included. All environmental permits required for the
facility were identified and the permit application contents defined. No fatal flaws were identified, but the
client saved considerable expense by adjusting the site boundaries to avoid wetlands that were of
concern to the Army Corps of Engineers, which was the lead environmental agency for the project.
