PREFACE
This document presents a control strategy designed to achieve
and maintain air quality in Alaska that is within the National Ambient
Air Quality Standards. The control strategy consists of a set of
control measures and procedures to be carried out and enforced by
the State and Regional A ir Quality ControlAgencies. This document
is divided into two books. This book presents a technical
summary of the Strategy. A second volume of appendices presents
the technical details, including all calculations.
This book is divided into six major sections.
Section 1.
OVERVIEW OF THE CONTROL STRA TEGY, presents an executive
summary of the Strategy. It describes briefly the air quality problem
in Alaska, it discusses the background for the problem solution
and presents the control strategy. The subsequent four sections treat
details of control Strategies for each of the four Alaska Air Quality
Control Regions. These sections present, for each region, the region
description, the existing regional air quality, the sources of pollutants,
the proposed control strategy and finally the economic aspects of
the control Strategy. The last Section 6. REFERENCES, gives a list
of the documents and other sources of data from which the strategy
was developed.

OVERVIEW OF THE CONTROL STRA TEGY
1. 1 INTRODUCTION
A control strategy is a time phased combination of specific
control measures designed to achieve the total reduction of air
pollutant emissions necessary for attainment and maintenance of
national ambient air quality standards. The individual control measures
that make up the control strategy are of many types, as deliniated in
Reference 7. A few examples of measures considered for Alaska
are: process and boiler emission limitations, a permit system to
regulate construction and modification of new facilities, traffic control,
fuel changes a.nd street sweeping.
Alaska is a very large State with a relatively small population of
only 300,0(10. Its population density is about 0.5 persons/square mile
which is smaller than the United States average density by two orders
of magnitude. Industrially, Alaska is in a developing stage and the
industrial density is also relatively small.
The State population and industry is concentrated in the two areas
around Anchorage and Fairbanks. About one third the population is
located at Anchorage and about one sixth at Fairbanks. Likewise,
industrial activities are cent~red around these cities.
1.2 A LASKAN AIR QUA LIT Y CONTROL REGIONS
Alaska is divided into four Air Quality Control Regions, as
designated by the Administrator of the Environmental Protection
Agency and the Constitution of the State of Alaska. The boundaries
of these control Regions are shown on Figure 1-1. The South Central
and the Southeastern region are very sparsely populated. The
Northern region is also sparsely populated, except for Fairbanks.
The Cook Inlet region contains more than a third of the State population
and about the same percentage of the industry.
As one would expect, the air quality for the most part of Alaska
is relatively high. However, certain natural peculiarities of the area
create air quality problems in Anchorage and Fairbanks. These
peculiarities involve the facts that much of Alaska is a bed of glacial
silt which is easily airborne when uncovered and very extreme temper-
ature inversions that frequently exist in Fairbanks.

Measurements and visual observations of air quality outside the
immediate area of Anchorage and Fairbanks show that its quality is
well within the limits set by the National Ambient Air Quality Standards.
Thus, these areas are classified as priority III for all pollutants.
Measurements of air quality in the Anchorage area have shown
24 hour average particulate concentrations of 711 flg/m3. This is
to be compared with the secondard standard of l50,M.g/m3. These data
are to some extent questioned because the samplers were at only
five feet elevation and therefore sampled both suspended and settleable
particulate matter. Still, they show that a definite particulate problem
exists. Anchorage is thus classified as priority I for particulates and
priority III for all other pollutants.
Measurements of air quality in Fairbanks give very similar results.
The annual geometric mean particulate concentration of 175 Jf.g/m3 is to
be compared with the secondary standard of 60 )Ag/m3.

. The carbon monoxide measurements show one hour maximum
concentrations of 81 mg/m3 compared to the primary standard of 40
mg/in3. These high carbon monoxide concentrations result when a steep
temperature inversion exist and the ambient temperature is very low.
Under such conditions shoppers and workers allow their cars to run
continuously to keep them warm.
Thus Fairbanks is clas sified as priority I for particulate matter
and for carbon monoxide. It is priority III for other pollutants.
The point sources of air pollutants in Alaska are located on the
maps submitted in the attached folder. The location of proposed air
quality surveillance sites are also shown. The legends explain the
significance of the v~rious symbols used.
Map I shows locations for all those sources outside the greater
Anchorage and Fairbanks area. The boundary lines of the four Air
Quality Control Regions are also shown on this map.

1. 3 CONTROL STRA TEGIES DEVELOPMENT
The development of the implementation plan and specifically the
control strategies sections were carried out within the guidelines of
the Federal Register of 14 August 1971. This section describes how
these guidelines were used in the development and selection of
appropriate control measures for the State of Alaska.
1.3. 1 Sulfur Oxide, Nitrogen Oxide and Oxidant Control Strategies
The guidelines covering the development of the control strategies
for these pollutants are described in sections 420. 13 and 420. 14 of the
above cited Federal Register. Neither ambient air quality measure-
ments nor source emission inventories indicate that a problem
existed with respect to any of these pollutants. Therefore, the control
strategy proposed basically consists of an expanded air quality surveil-
lance network and a permit system for the evaluation and control of
construction of new sources of these pollutants.
The sole exception to this strategy type is in the area of sulfur
oxide emissions from two power plants located in the Southeast Alaska
AQCR. The sulfur oxide emissions from these plants cause localized
ambient air concentrations in excess of the National Ambient Air Quality
Standards (NAAQS). Specific control regulations requiring application of
reasonably available control technology are proposed to limit these
emissions and a program for developing and enforcing compliance
schedule is presented as a part of the control strategy for this AQCR.
1-4

-------
1.3.2 Particulate Control Strategy
In most areas of the State suspended particulate measurements
and estimates are well below the secondary NAAQS. For these regions
a preventive control strategy based on air quality surveillance and
the control of construction of new pollution emission sources is
proposed.
In two areas of the State, the greater Anchorage portion of the
Cook inlet and the Fairbanks North Star Borough of the Northern Alaska
AQCR, particulate concentrations above the primary national standards
have been measured. A detailed procedure of control strategy develop-
ment, as outlined in section 420. 13 of the Federal Register, was applied
to these cases.
In the greater Anchorage area, only a relatively small fraction
of the suspended particulate loading can be identified with industrial/
commercial type sources of emission. Atmospheric diffusion estimates
indicate that a majority of the particulate matter is caused by either
natural sources of wind-blown dust or traffic generated dust from road
ways. However, it was neither possible to quantify the contributions
from these sources nor to assign a specific particulate matter background
level to the region with the available data because the air quality data
were made such that both suspended and settleable particulate matter
were collected. The analysis indicated further that application of
reasonably available control technology to stationary sources would
not reduce ambient concentrations below the primary NAAQS.
The control strategy proposed consists of three basic sets of
actions. First, regulations will require all stationary particulate
emission sources to control to the extent of reasonably available
control technology. This step is required in light of the measured
ambient concentrations but, as stated above, will not be sufficient
to reduce concentrations to acceptable levels. Second, a sequenced
program of applying control measures to reduce traffic generated dust
will be instituted. These measures are of the type listed for the control
of fugitive dust in Reference 7 , Appendix B. Third, a detailed
program of air quality surveillance and special studies to determine
the effectiveness of controlling fugitive dust are proposed.
1-5

-------
This air quality surveillance program will allow the control agency
to refine the control strategy application periodically during the course
of the implementation plan, and will allow maximum effort to be placed
on the attainment of NAAQS by 1975.
In the Fairbanks North Star Borough the situation with regard
to suspended particulate concentrations was roughly similar to that
in Greater Anchorage area. However, the winter particulate levels
in Fairbanks appeared, on the basis of atmospheric diffusion calculations,
to be caused mostly by stationary sources. These sources will be con-
trolled by regulations dealing with fuel combustion. stion.
The summer particulate levels and the annual average concentrations
observed in Fairbanks appear to be significantly influenced by fugitive
dust and! or smoke from forest fires. A phased application of fugitive
dust control measures concurrantly with increas ed air quality
sampling and special studies, to further define the problem, is prc-
posed for this region.
1.3.3 Carbon Monoxide Control Strategy
In most areas of the state no carbon monoxide problem can be
envisioned based upon either ambient measurements or source con-
centrations. However, in the Fairbanks North Star Borough extremely
high levels of carbon monoxide have been measured. A detailed analysis
of the problems, was applied based upon the guidelines supplied in
Section 420. 14 of the Federal Register.
The high ambient carbon monoxide levels appear to be caused
by a combination of cold weather driving habits and limited diffusion
potential of the atmosphere during prolonged inver sion conditions.
Thus, the problem seems to be specifically related to the unusual
climatic conditions occurring in the Fairbanks area.
Development of a control strategies to this problem were affected
by the pecularities of the area. The influence of the Federal Motor
Vehicle Standards on the reduction of automotive pollution emis sions
were difficult to quantify since the best available estimates were
based on urban driving conditions in moderate climates.
The fact
that Fairbanks is a relatively small urbanized area limited, to some
extent
the type of control measures, such as traffic rerouting
1-6

-------
in conjunction with mass transit, that could be considered in the problem'
solution. The ice fog problem, occurring at low temperatures,
complicated the task of finding solutions since certain proposed control
measures, such as switching motor vehicles to alternate fuels, aggravate
the ice fog problem. The lack of a true measure of the temporal and
spatial extent of the CO concentrations hampered the control strategy
development.
The recommended strategy to control carbon monoxide in this
area followed from the consideration of a number of possible control
measures. The basic strategy called for a time sequenced set of control
actions. These actions are designed to improve traffic flow in the down
town area, reduce unattended idling time by regulation, by installation
of electrical plug-ins for car heating and to switch to a Propane fuel
if ambient levels do not improve within a two year period.
. A keystone of the proposed control strategy is the continuation
and extension of air quality monitoring for carbon monoxide in the
Fairbanks North Star Borough. The monitoring data will be periodically
reviewed to indicate progress made towards the solution of the problem
and optimum control of alternatives to be implemented at any particular
point in time.
1.3.4 Schedule for Compliance
The entire control strategy was designed on the basis that
National Ambient Air Quality Standards will be achieved within three
years following approval of the implementation plan. All,
identifiable stationary sources will be in compliance with the proposed
emission limitations by the end of this time. The initiation of control
measures, as described above for particulates and carbon monoxide,
will allow considerable reduction in the pollutants emissions to be
achieved within the three year period. The proposed control
strategy provides sufficient checkpoints in terms of air monitoring
quality and control strategy applications that a maximum possible
result in terms of ambient air concentrations should be achieved.

-------
1.3. 5 Intra and Interstate Influences of Emissions Sources
Section 420. 10 of the Federal Register requires that consideration
be given to the impact of emission sources. located in one region
on ambient air quality in other areas. The air quality control regions
are very large in Alaska and populated areas are separated by several
hundred miles. There are no known or suspected instances where
pollutant emissions in one region affect the air quality in another.
Alaska I s location makes interstate effects unlikely and the location
of sources within Alaska makes international air quality degrad-
ation very improbable.

1.4 GENERAL FEA TURES OF CONTROL STRA TEGIES
1. 4. 1
Preventive Aspects
The control strategy for the State of A laska as presented in the
implementation plan will be evaluated as a strong preventive program
with the exception of three areas where corrective programs are required.
Most areas in the State now enjoy almost perfectly clean air. In only
three specific cases are national primary or secondary ambient air
quality standards thought to be exceeded. The desire to maintain this
environmental quality will be achieved by rules and regulations of the
State of Alaska proposed as part of this implementation plan. A set
of strong emission limitations, are required to provide the basis for
an environmentally sound development of the State's resources. The
registraHun and permitting system gives the State and local air
polluti.un control agencies the tools required to effectively protect the
ambient air quality.
1.4.2 Use of Air Monitoring Studies
In addition to the general air quality surveillance system, each of
the proposed special studies will supply information vital to the design
or implementation of effective control measures. The detailed
descriptions of these studies are presented in the Air Quality Sur-
veillance Volume of this Imp1emental Plan; the specific application of
these studies to the control strategy is discussed below.
The determination of the amount of automobile traffic-generated
particulate material will significantly affect the particulate control
strategy for both Anchorage and Fairbanks. If particulate road
conditions and/ or modes of vehicle operation are shown to be pre-
dominant in the generation of airborne particulate material, then a
revision or realignment of the control strategy would be carried out.
Conversely, if vehicle operations are not shown to be significant
contributors to the regional suspended particulate problem, then
other types of special air quality monitoring studies would be indicated.
The determination and evaluation relationship between sampler
elevation and measured suspended particulate concentration will assist
further control strategy development and implementation in two ways,
1-9

-------
First, these data will allow a more informed appraisal of the results
of previously collected air quality data. Secondly, sampler elevation
data should indicate to what extent particular sampling locations are
influenced by nearby or distant pollution sources. In both of the above
ways, the study defining the relationship between sampler elevation
and suspended particulate measurement can assist agencies in
evaluating the selected control strategy and may provide the basis
for strategy revisions.
Measurement of the size distribution of suspended particulate
material will further define the nature of the suspended particulate prob-
lem in Anchorage. The true health significance, in terms of amount of
respirable dust, can be ascertained with these measurements. Also, the
effectiveness of various control measures, both on a local scale and region-
wide, can be judged on the basis of the particle size data. For instance,
if a significant fraction of the total particulate loading is caused by parti-
cles 10 microns or larger in diameter, then sources in the immediate
vicinity of the sampler (such as traffic) probably predominate since large
particles are not generally transported over great distances in the atmo-
sphere. A correlation of high dustfall measurements with high suspended
particulate readings provides a similar indication, although in a more
qualitative sense.
Each of the special studies will be an aid to the more explicit defini-
tion of the particulate problem in Anchorage and Fairbanks in particular
and in Alaska in general. As each study is completed, it will be possible
for the control agencies to more specifically plan appropriate control
activities and to concentrate on thos e control strategies which are indicated
to be most effective in terms of the actual suspended particulate problem.
The measurement of certain hazardous air contaminants (e. g. ,
mercury, beryllium, lead, asbestos, etc.) as special monitoring studies
will assist the control agencies in protecting the health of State residents.
Although these pollutants are not specifically addressed in this Implemen-
tation Plan, control measures for them will be required in the near future.
The background information gained from this study will be invaluable in
assisting in the development of effective agency plans at that time.
1-10

-------
Air quality sampling at remote locations will provide the operating
control agencies with two direct benefits in terms of control strategies.
First, background measurements obtained at locations relatively remote
from existing sources or population concentrations provide excellent back-
ground information on naturally occurring pollutant levels. Agency per-
sonnel will also become familar with the topographic and meteorological,
peculiarities of the areas studied. Second, the impact of any proposed
industrial developments in the regions sampled could be effectively
evaluated. Each source's contribution to the existing ambient pollution
levels could be estimated and the appropriate pollution control measures
specified before an air quality degradation results. The necessity for
measurements at selected remote locations is, therefore, obvious in
terms of a comprehensive preventive control strategy.
1. 4.3 Use of the Permit System
, The proposed permit system described in the Permit System Volume,
of the Implementation Plan forms an integral part of the overall air pol-
lution control strategy. The most carefully designed control strategy is
of no value in achieving and maintaining National Ambient Air Quality
Standards unles s it is completely and universally enforced. This is the
function of the permit system. The three basic areas in which the permit
system facilitates the implementation of the control strategy are'discussed
in the following paragraphs.
First, the permitting of sources of atmospheric pollutant emissions
provides the cognizant control agencies with a formalized mechanism for
securing compliance of existing air pollution sources with air pollution
control regulations. All sources affected by the control regulations must
submit a registration application to the appropriate control agency. If
the source has emi~sion rates greater than those allowed by the regulation,
the permit system provides for the negotiation and enforcement of a time
schedule by which the source will reduce its emissions to the prescribed
level. The use of the permit system in this context is more full des cribed
in the Permit System Volume dealing with com~liance sc~edules.
The permit system, through its permit to construct provisions,
provides an explicit method by which new sources (or modifications of
existing sources) can be integrated into the overall control strategy.
1-11

-------
The appropriate control agency must be informed prior to construction
not only of the existence and location of the proposed source but also
of those operational characteristics which affect air pollutant emissions.
Detailed review procedures carried out both before construction and
prior to operation will insure that all new sources comply with applicable
emission limitations. The control agency will be able to determine,
by means of the information supplied by the source operator for review,
whether the construction and subsequent operation of the source is
likely to degrade the air quality in the region to below secondary
NAAQS.
After a permit is granted, it must be reviewed periodically, and
this allows the agency to regulate operating sources in the same way.
Thus, with proper administr~tion of the permit system described in
this plan, attainment of the NAAQS will be facilitated, and AQCR's
which are presently clas sified Priority III will be prevented from
exceeding the secondary standards.

1.4.4 Projections of Growth and Air Quality
Population growth projections were made for the greater
Anchorage area and for the Fairbanks North Star Borough on the basis
of projections of the Labor Department. The projected growth rate
is 3% per year for both areas.
Air quality projections are based on projected emissions from
stationary and mobile sources. The ground rule in determining
emission reductions required to meet the NAAQS is to assume that
all stationary source emissions increase at the rate of 3l/:! per year
as do mobile source emissions with the exception of gasoline powered
motor vehicles. While the car populatio~ growth, is projected
to match population growth; the carbon monoxide reduction, due to
Federal Regulations on car emissions, is calculated for normal
driving. However, the emissions inherent due to cold weather driving
and idling are assumed to grow as the car population growth. This is
a very conservative assumption, necessary because the Federal
Regulation addresses driving conditions in a far more temperate
climate and has an undefined impact on either extreme cold weather
idling or driving.

1.5 SUMMARY AND CONCLUSIONS
1. 5. 1 Cook Inlet Intrastate AQCR
A 40% reduction in the concentration of particular matter in the
Cook Inlet AQCR is required for meeting the secondary NAAQS. The
air quality reduction cannot be re lated to a percentage roll back of point
source emissions, since the major portion of the existing particulate con-
centrations result from natural causes and road traffic. Applications of
reasonably available control technology are a recommended control meas-
ure. Road and street paving, road oiling, and wet street-sweeping are
also recommended control measures, although accurate predictions of their
effects cannot be made.
Control strategies for other pollutant species consist of preventive
measures, such as fuel regulations and will be monitored by the permit
system.
1.5. Z Northern Alaska Intrastate Air Quality Control Region
A 60% reduction in particulate concentrations is required to meet
NAAQS. The causes and control measures discussed in Section 1.5. 1
apply in Fairbanks.
reasonably available
mended.
A 50% reduction in CO concentration is required in this AQCR. The
high CO concentration in this region results mostly from cold weather
driving and idling of automobiles. The Federal motor vehicle regulations
for CO emission reduction will provide a 12% net reduction in emissions by
1975, and a Z 7% net reduction by 1977. Regulations will be adopted which
prohibit unattended car idling which will result in a 15% reduction. Further
a city by-pass highway to be complete in 1973 will reduce traffic and CO
emissions by about 100/('.
Control strategies for other pollutant species consist of preventive
In addition, power plants are contributors, and
technology controls on stack emissions are recom-
measures only.

1. 5.4 Southeast Alaska Intrastate AQCR
High ambient levels of 502 occur in two localized areas, due to
the presence of pulp mills. Emission limitations by regulations requiring
reasonably available control technology will result in the attainment of
secondary standards in these areas within the scheduled period for attain-
ment of primary standards. This represents a 300/(' reduction (to secondary
standards) in the ambient concentration of 502 in these areas.
Control measures for other pollutants in this region are preventive
in nature.

THE COOK INLET INTRASTATE AIR QUALITY CONTROL REGION
2.1 REGIONAL DESCRIPTION
2.1.1
Topography and Climatology

This Air Quality Control Region is located in and around the Cook
Inlet Basin. It consists of the Greater Anchorage Area Borough, the
Kenai Peninsular Borough and the Matanuska-Susitna Borough. The basin
is surrounded on three sides by high mountain ranges: the Alaska Range
to the west and north, the Talkeetna Mountains to the northeast, the
Chugach Mountains to the east, and the Kenai Mountains to the south.
The basin opens into the Gulf of Alaska and the Pacific Ocean through the
Cook Inlet. The Inlet which runs southwest from Anchorage, is 20 to 30
miles wide and about 100 miles long. The map in Figure 2 -1 shows the
boundaries of the AQCR. Three more maps showing the region in increas-
ing detail can be found in the folder.
The city of Anchorage lies ln a broad valley with adjacent narrow
bodies of water. The Chugach Mountains to the east form an effective
barrier to the influx of warm moist air from the Gulf of Alaska. The
Alaska Mountain Range to the northwest and northeast acts as a barrier
to the influx of very cold air from the north. Cold air entrapment in some
suburban areas tends to offset this sheltering effect, resulting in occa-
sional extremes of l5° with temperatures 150 to 200F colder in the suburbs.
Seasons are well defined in Anchorage with winter exte'nding from
mid-October to mid-April. Winter is characterized by cloudy, mild
weather alternating with clear, cold weather. The clear, cold days are
frequently accompanied by significant ground fog caused by moisture from
the arms of Cook Inlet. Snowfall occurs from mid-October to mid-April.
Normally, the depth of snow cover on the ground does not exceed 15 inches.
Strong, gusty winds occur infrequently during the winter months. Spring
is the period following the "breakup." This season is characterized by
warm days and chilly nights. Precipitation is negligible. Summer com-
prises the period from June through early September. The latter half of
the season accounts for about 40 percent of the annual precipitation.
Autumn is brief, beginning shortly after mid-September and lasting until
2-1

Some of the stronger southerly winds occur in late summer or fall.
2.1.2 Soil Characteristics
The soils in the Anchorage area are podzol soils found especially
in regions having hum.'d, cool clima.te (ReferencelS, p. 7). Podzolation
to form soil of this type involves leaching of the upper layers with accu-
millation of heavier material in lower layers. The podzol soils have an
organic mat and a thin organic -mineral layer above a gray leached layer
resting on clay enriched alluvial horizon. * Thus, the upper layers of soil
of the area tend to be sandy, grainy and loosely packed, characterized by
a thin cover of loess and by sandy dunes (ReferencelS' p. 6). The well-
developed podzol soils are ashy in appearance because of the extreme
leaching 01 soluble salts and organic matter. Loess is small sized
particulate material deposited by the wind; thus, like sand, it is readily
blown by the wind whenever the ground cover is disturbed or rernoved.
2.2 PRESENT AIR QUALITY
The air quality control region is classified Priority I only for
particulates. It is classified as Priority III for all other pollutants.
The air quality data available for this region are discussed and
evaluated in the Air Quality Surveillance System Volume. Two maps
included in that volume show the locations of the point sources in the
air quality control region. The location of the major point sources are
shown on the enclosed maps I, II, and III. The results of the air quality
data evaluation are summarized and compared to the National Ambient
Air Quality Standards in Table 2-1.
Air quality data relating to SO and NO are considerably below the
x x
primary national standard. No data are available for CO, hydrocarbons

or photochemical oxidants.
The highest particulate concentrations were measured in the central
part of Anchorage. The available air quality data are not sufficient to
permit identification of all sources of suspended particles of dust, as
discussed below, and the air quality surveillance system proposed in the

Air Surveillance System Volume will provide information necessary to
identify the sources of suspended particulate matter and to implement
control measure s leading to the desired air quality
The high particulate matter concentrations measured in the Cook
Inlet region are related to the topography, meteorology and soil quality
of the region, as well as to the man-made particulate emission sources
identified in the Emissions Inventory (Reference 20).
National Air Surveillance Network (NASN) data for 1969 and 1970
and data from the Triborough Air Resources Management District for
eight stations for March 1969 to March 1971 are available. The local
data were sampled at an elevation of 5 feet; the NASN data at an elevation
of 26 feet.
2.3 PROJECT ED REGIONAL GROWTH
2.3.1 Population Growth
About 40% of the total population of the state of Alaska live in the
greater Anchorage Area (References 10 and. 25). The Department of Labor
forecasts a population increase of 7.30/0 between 1971 and 1975 (Reference
4) while an extrapolation of the Gr~ater Anchorage population growth
(Reference 10), as shown in Figure 2 -2, indicates a 17% populatioh increase.
However, much of the Anchorage population growth in the 1960's can be
attributed to the expansion of the military bases - an expansion that will
not neces sarily continue. The recent discovery of oil and the population
increases that may be expected from the possible construction of pipelines
will probably not be felt before 1975. In view of these factors a growth
projection of 12% of the population and, consequently, of area source
pollutant emissions was adopted as a ground rule in the evaluation of
man-made emissions for 1975. This ground rule has little impact on the
design of control strategies, as discussed later.
Growth rates of pollutant emissions from specific industrial and
commercial s.ource categories are discussed in 'the follo~ing section.

2.3.2 Potential New Point Sources
Two new potential point sources of major size have been identified
for the Cook Inlet area; a petroleum liquification plant and a cement plant. ~'<:
The expected emis sions from the former will involve considerable NOX
caused by natural gas combustion in gas engines and/or turbines driving
compressors. Up to 7,300 pounds of NOX can be expected to be generated
for each mmcf of natural gas used in this manner. The actual size of the
plant is undetermined at this time but its location has been established
in the Kenai Peninsula area.
The cement plant, to be located in the Anchorage area, is projected
to have aI, 300,000 bbl annual capacity. The particulate emis sions from
such a plant are typically 44-64 lbs/bbl uncontrolled, depending on whether
a wet or dry process is involved. With available equipment which is about
990/( efficiency, the potential particulate emissions would be approximately
285 to 415 tons per year.
Based on the above considerations, neither of the above sources
appears to have a major impact on air quality in the Cook Inlet area. A
summary description of these sources is given in Tables 2-2 and 2-3.
2.4 EXISTING SOURCES OF AIR POLLUTANTS
2.4.1
Particulate Matte r
Examination of the man-m::tde emission sources included in the
Emission Inventory (Reference 20) shows that 76% of identifiable particulate
emissions in the Cook Inlet area are attributable to transportation
(Reference 20) page 22). The remaining 24% is caused by stationary
sources. The total emission rate of particulates from point and man-mr.\.de
area sources not including traffic generated dust is 2626 ton/year
(Reference 20) page 10).

Table 2-4 shows the emission rates of all point sources in the
region. The tabulation indicates all sources in excess of 10 tons per year,
current emissions, and where applicable, the 12% growth rate projected
for 1975. The allowable particulate emissions from fuel combustion were
calculated on the basis of 0.3 lb/l06 Btu of heat input (Reference. 7 ,
Appendix B). This figure is generally applicable to solid fuels, however,
as the table indicates, the fuel used in the Anchorage area is primarily
natural gas, a fuel which contributes relatively little particulate matter
emission. Allowable particulate matter emissions were calculated on
the basis of reasonably available control technology as defined in Reference
23, page J.5495. As a result, the allowable emissions appearing in Table
2 4 are exceeded only in the case of source 72, a process source.
The locations of point sources emitting in excess of 100 tons per
year of particulates or CO are shown in Figure 2-3. Of the point sources
shown, four have particulate emission rates higher than 100 ton/year.
One source is an oil platform (No. 30, Figure 2-3), flaring natural gas.
Its particulate emissions contribute 5% of the yearly particulate emissions
included in the inventory. Another particulate point source is the
Elmerdorf Air Force Base Airport (No. 69, Figure 2-3). Its contribution
to particulate emissions amounts of 10% of the total. The third source is
the Anchorage International Airport (No.1, Figure 2 -3) which c

relatively remote from populated areas and do not contribute significantly
to the higher measured concentrations found in the city. As mentioned
above, they will be terminated during 1972 and are not considered further
in the control strategy development.
2.4. 3 Sulfur Oxides
Only four point sources of sulfur oxides are found in the Cook Inlet
AQR. Two of these, (No. 29 and 69) are airports, the other two (No. 76
and 94) are diesel installations on oil platforms in the Cook Inlet (see map
A). The total emissions from these sources are insufficient to degrade air
quality in the Cook Inlet AQR to the level of the secondary NAAQS.
2.5 IMPACT OF EMISSIONS ON AIR QUALITY
Conversion of pollutant emiss ion rates to an air quality can be made

using a diffusion model which treats each source separately, or by use of

an area model (Reference 6, Appendix A). A diffusion model is not

available for the Region, therefore the area model estimation procedure

was used. The estimation is highly dependent upon the choice of the

basic "urban area." Several reasonable choices are available, which

includes the following three:

1) Area of the city of Anchorage, 129.5 km2.
2
2) Area of Greater Anchorage, 184 km .

3) Area of "air shed" (Figure 2.4) which is bounded
by the 1000 - foot elevation line on the eas t the
seashore on the west; and was selected straight 2
east-west lines on the north and the south, 450 km .
A typical average wind speed for this area of 2 9 ml sec was used
in the calculations (see Appendix 2A). The calculated air qualities
corresponding to these urban areas, respectively, are:
= 27 g/m3
= 20 g/m3
= 10 g/m3
Much higher particulate concentrations are habitually measured in the
downtown section of Anchorage which suggests that the calculation
procedure is questionable. Several obvious shortcomings include our
estimate of the urban size. The true area over which the pollutants are
distributed is not really known. A second shortcoming is the knowledge

of all the sources of particulate water. Sources of particulates not
included are traffic-generated road dust, dust from exposed soils or
blown in from glaciers and moraines, and smoke from forest fires. The
extent of the contribution made by these sources is examined in the follow-
ing section.
2.5. 1 Aix: Quality Data II?plications
The suspended particulate measurements taken in Anchorage from
1963 to 1970 (Reference 6) are tabulated in Appendix 2B and illustrated
in Figures 2B-l through 2B -4. These data indicate that there are two
seasons of the year in which a maximum particulate matter concentration
occurs in Anchorage, spring (April/May) and the fall (September/October).
As pointed out in Reference 12, this is a predictable pattern. The spring
thaw comes in March and by April considerable road dust develops.
Mud
tracked in by motor vehicles and the dry road surface recreate a dusty
condition. After the rainy season in June and July, the unpaved roads
are graded in orde r to be smooth for the winter. Thus, the unpaved road
surfaces are again a source of loose soil in September and October until
a winter frost and snowcover begins. The minimum particulate count
occurs during the winter months, November through March.
Table 2C -1 of Appendix 2C shows quarterly maximum and minimum
particulate concentrations measured by the NASN. The average varia-
tion between maximum concentrations measured (second or third quarter)
and minim'.lm concentrations (first or last quarter) is 65%. Since no
identifiable man-made source would account for such a variation, it is
reasonable to conclude that about two-thirds of the suspended particulate
in the Anchorage area may be generated by sources not considered in the
Emi s s ion Inventory.
Examination of air quality data presented in Table 3.2. 1 of the Air
Quality Surveillance Volume, for the ye ars 1957 through 1964 shows a
marked decline in particulate concentrations during those years. This
decline, achieved despite a large increase in population and in traffic
volume, can only be attributed to the effectiveness of road and street
paving in reducing suspended particulate concentration. However, the
2 -14

-------
decline is not steady - indicating a considerable contribution from natural
sources, such as volcano eruptions, and forest fires. The contribution
from less predictable sources, such as dust blown in from moraines, silt
beds and glaciers cannot be separated from traffic generated dust today.
2.5.2 Potential Sources of Particulate Matter
Top soil quality in the Anchorage area is such that a great deal of
dust is generated wherever the soil surface is exposed. A large number
of glaciers surround Anchorage. Moraines and silty river beds are
potential sources of wind generated atmospheric dust.
Although there are few fires in the Anchorage area which could be
classified as forest fires, periodic smoke emissions from distant fires
do reach the area in the summer months. These emissions, coupled with
considerable quantities of open burning during land clearing in the Greater
Anchorage Area Borough, can make a significant contribution to the
particulate concentration in the air.,H6wever, suspended particulate
concentrations have not been shown to increase when visibitity ~s decreased
by a forest fire. In the one case where data is available, the fire was
probably too far .a'W~y (east of Fairb~nks) to draw informative. conclusions.
Further investigation~ of these sources of particulate are necessary.
The traffic patterns that exist in the Anchorage metropolitan area
reflect the land use patterns that have evolved in-the community. Primary
industrial and commercial activity is centered in the downtown business
district and near the International Airport. The predominant land use in
most of the metropolitan area is residential of various densities. Land
use patterns are shown in Figure 2-5 (Reference 9). The traffic patterns
presented in Figure 2 -6 and 2 -7 (Reference 26) indicate that the largest
traffic volumes occur on main thoroughfares which interconnect the resi-
dential areas with the com~ rcial/industrial areas and also those that
serve the two military bases: Elmendorf Air Force Base and Fort Richardson.
An examination of Anchorage metropolitan area road maps and
available information concerning the condition of roads in Anchorage
(Reference 10) show that only 45% of the roads and alleys in the city of
Anchorage and only 20% of the roads in the service areas of Spenard,
2-15

-------
Muldoon and Sandlake are paved. The main traffic thoroughfares pre-
sented in Figures 2 -6 and 2 -7 are paved but many of the roads in the
residential areas leading onto the main thoroughfares are unpaved. In
addition to city and borough maintained roads, there are many miles of
private roads. Traffic produced dust which adds to the suspended parti-
culate concentrations will be produced by vehicles on the unpaved roads
within the central business district (CBD) and the residential and service
areas. Additional dust will be carried into the city by vehicles that have
been driven on unpaved roads.
Paved roads in Anchorage are quite dusty and, or course, traffic
generates dust on the unpaved roads. A central strip of dust and dust
deposits near curbs can be seen in the business district of Anchorage.
Cars driving across the central strip or along the curb raise a cloud of
dust, particularly if their speed is high. Sitnilar~y, access roads to the
business district are dust producers. The center strip is covered with a
thick layer of dust and the shoulders are unpaved. Any car straying from
the center of a traffic lane, maneuvering to pass another car or to pull
off the road, generates a great deal of dust. Unpaved roads, of course,
are the biggest dust producers. Traffic on unpaved roads isgenera!ly
no slower than on paved, and all cars raise large dust clouds. These
sources of particulate matter cannot be quantitatively defined at fhis time.
A correlation between traffic-produced dust and suspended particu-
late concentrations in the Anchorage region is not available although an
attempt was made to examine and correlate traffic flow and road surface
conditions to dust production. The special studies proposed in the Air
Quality Surveillance Volume will lead to a mor e definitive unde rs tanding
of this phenomenon. When a correlation between dust fall and suspended
particulate concentration becomes available from the special studies, a
further correlation between road paving and suspended particulate concen-
trations will be possible.

PROPOSED CONTROL STRA TEGY
Measured concentration of particulate matter in Anchorage
indicate mean annual values of about lOO/Cg/m3. Thus a reduction of
suspended particulate of about 40% is required to meet the Secondary
National Air Quality Standard. Unfortunately, it is not presently possible
to re late this improvement to a' percentage roll back of pollutant emissions
from sources because the background levels are unknown. Seasonal
variations of about 650/1.' of the measured concentrations between summer
and winter indicate that a significant fraction of the observed particulate
matter is caused by sources other than the conventional point and area
sources. Traffic generated dust is probably the largest contributor,
however an accurate quantification of the traffic dust contribution cannot
be made with the available i~formation. An aggressive control strategy
is proposed in which reasonably available control technology is applied
to industrial sources and a program of control measures are instituted
directed at reducing traffic and other sources of dust. A special studies
program will be carried along in parallel with application of these
control measures which has the goal of accessing the progress of the
plan and of further defining the air pollution problem. This control
strategy will remain flexible so as to find solutions to the problems
defined.
The proposed control strategy will achieve the
on particulate matter by 1975.
The control strategy,is summarized below:
1972
secondary standard
Pave 17 miles of streets in Greater Anchorage Area
Borough by 1973. This is in accordance with the
Borough's paving plan as it stands today according to a
communication from the Borough Planning Department.
An increase in the paving schedule is not presently
recommended since this is a very expensive measure
($40, OOO/mile) and its effectiveness is not clear.
Increase street cleaning frequency from May to
September. Four wet street sweepers are currently
operated in the Greater Anchorage Area. These sweepers
operate for 8 hours/day, 5 days/week, covering a total
of 28 miles of roadway per day. It is proposed that this
operating schedule be increased so that at least 40 miles
of streets are cleaned each day. This increased effort
should be concentrated in the center city area and on
2-20

-------
1973
major arterial streets. The exact schedules and routes
will be negotiated between the Tri-Borough Air Pollution
Control Officer and the Borough Road Maintenance Depart-
ment.
.
Oil soft road shoulders on main access roads and gravel
roads between May and September. This extention of the
current oiling program to include the soft shoulders of
paved access roads will be initiated to attempt reduction
in the amount of loose material carried onto hard-surfaced
roads.
o
Initiate a planting program on all lands from which ground
cover has been removed (strips along roads, vacant lots,
construction sites after work completion).
o
Require street cleaning around construction areas where
trucks track dirt onto public roads. Construction sites
which require considerable hauling to and from the site
will be subject to daily road sweeping to control dust
resulting from truck load losses. Road sweeping will
be performed in mid-morning and mid-afternoon on heavily
traveled roads servicing the construction areas. Additionally,
gravel hauling in these areas will be controlled by requiring
dump trucks to provide a dust cover over the carriage.
These restrictions will be in effect in the City of Anchorage
and in the Muldoon, Spenard and Sand Lake Service Areas.
o
Evaluate dust fall and air quality data collected in 1972
(See Air Quality Surveillance Volume). Accelerate the
most effective measures tried in 1972, and if feasible,
replace sand-salf mixes on streets and roads in winter
by 3/8-inch chips of quartz rock (such as used in Fairbanks).
This would eliminate the approximately 10,000 tons of sand
used annually in the Greater Anchorage Area.
o
Continue the control measures instituted in 1972.
1974
.
If Primary Air Quality Standards have been met, establish
new schedules for paving, street cleaning, road and road
shoulder oiling, to meet secondary standards.
2-21

-------
.
If primary standards have not been met, accelerate all
programs to:
1)
Reduce unpaved road mileage to zero by 1975 for
streets used by 1000 or more vehicles! day
Clean streets downtown daily
2)
3)
Oil road soft shoulders six times each year for all
roads utilized by as many as 500 cars! day
4)
Require that exposed dirt during construction be
covered as soon as feasible
5)
Require daily street cleaning around any construction
The above program, specifying a variety of control measures and
annual progress reviews, is required because of the undefined nature of
the suspended particulate problem in this area. Continual review of air
quality data as generated by the air quality surveillance system .and the
special study will be essential in achieving the air quality standards by
1975.
2.7 ECONOMIC ASPECTS OF THE CONTROL MEASURES
The following cost estimates were derived for the recommended
control strategies. The detailed calculations are given in Appendix 2E.
The results of these calculations are shown in Table 2-5. These
estimates have been provided by the appropriate governmental agencies
(i. e., Alaska Department of Highways, Greater ~nchorage Area
Borough Department of Roads, etc.).

2.7. 1 Costs of the Plan For the First Year, 1972, are as. follows:
. Paving - No cost attributable to the implementation plan since
this program is in accordance with the paving plan as it
stands today.
. Increase in street cleaning by wet sweeping from 28
miles to 40 miles per day from May to September.
Increment in cost ( 40 - 28) x 1000 = 12,000 dollars/year.
. Oil road soft shoulders and gravel roads. The current oiling
program of gravel roads is not known accurately; schedules
and miles oiled are largely determined by other demands on
men and equipment. We shall assume that the increase in the
oiling frequency for gravel roads is four times per year and
that road shoulders will be oiled four times a year.
Total number of unpaved roads in the Service Areas (Spenard,
Muldoon and Sandlake): 102 miles, oiling costs are
102 x $2560 = 262,000 dollars /yr.
Oiling of road shoulders on the following major roads is
recommended:
Glenn Highway and 5th Ave - from the CBD to Muldoon Rd.
3.9 miles.
Seward Highway - from the CBD to Huffman 6.7 miles.
Tudor Rd, Muldoon Rd - 6.9 miles.
Boniface Parkway - from Thedor Rd to Glenn Hwy - .
2.8 miles.
Northern Lights Blvd. - between Boniface and Turnaagen
5.0 miles.
IntI. Airport Road. - between the airport and Seward
Highway.
Debarr Road and 15th Ave - from the CBD to Muldoon Road
3.4 miles
Total: 32 miles.
The cost of oiling the 32 miles of road shoulders four times
a year is 32 x 860 = 27,500 dollars

Costs of plan'ting cannot be estimated as no similar program
under the climatic conditions of Anchorage exists today.
.
2-23

-------
.
Similarly no basis for the estimation of street cleaning costs
around construction sites could be found.
The total estimated cost in 1972 is 12,000 + 262,000
+27,500 = 30l,500dollars/year.
The costs of the proposed control strategy for the 1972-73
period were not made because the exact nature of the measures
are so dependent upon the success of the 1972 measures.
Estimation of cost incurred in the installation of control devices on
taken
stationary or mobile pollution sources can be made with some degree of
accuracy. Evaluating what portion of the cost of road paving and mainte-
nance should be assigned to the implementation of the Clean Air Act is
not so simple. As growing population concentrations are transforming
what used to be a settlement into an urban center unpaved streets and
roads becoine increasingly u~acceptable. Increased mileage of paved
roads and streets and increased maintenance go hand in hand with urbani-
zatiol1.
The Clean Air Act requirements may speed up the process,
but since the rate of the proces s cannot be projected in the first place
(road paving programs and maintenance budgets are subject to citizen
control), the future incremental cost can hardly be projected. The costs
shown, then, are only useful as rough guidelines and the actual implemen-
tation of the proposed control measure must be closely coordinated with
Borough Planning and Budgetary agencies. This will be a continuing
process.
A thorough examination of expenditures and air quality improvement
will be made periodically from 1972 to 1975. The results of the special
studies, correlating dust fall and suspended particulate concentrations near
roads will be used to determine the most cost-effective control measures,
i. e., the amount of money expended to achieve a given particulate con-
centration reduction. The program for the following year can then be
implemented with good assurance that the needed reductions iri particulate
concentration will be obtained without unnecessary expenditures.

THE NORTHERN ALASKA INTRASTATE
AIR QUALITY CONTROL REGION
3. 1
REGIONAL DESCRIPTION
3.1.1
Topography and Climatology
The Northern Alaska Intrastate Air Quality Control Region con-
stitutes those portions of the 1956 Election Districts 18 -23 which are
not included in the designated Cook Inlet Intrastate Air Quality Control
Region. The boundaries of the region are shown on Figure 3 -1. This
region includes the Fairbanks North Star Borough, which accounts for
the bulk of the population and economic activity of the region. The
remainder of the region has neither significant urbanized areas nor
large air pollutant emission sources; therefore, the control strategy
developed is for attainment of the NAAQS in this borough and maintenance
of the air quality in the rest of the region.
Fairbanks is a city located on the Chena River, in a basin surrounded
by hills on the northwest, north and northeast. The Tanana River plain
lies south of Fairbanks and borders on the Alaska Mountain Range at the
south. The Fairbanks area has the severe continental climate of interior
Alaska. The sun is above the horizon for 18 to 21 hour s each day during
the months of June and July. In December the sunshine period declines
to les s than 4 hours per day (Reference 24). Temperatures in the summer
reach about 900F and fall to -60oF in the winter.
3. 1. 1. 1 Wind Characteristics
The prevailing low level winds are north and northeast in winter
(December, January, February), north in spring and fall (March, April,
May and September, October, November), and southwest in the summer
(Reference 3, Figure 5). Prevailing upper air winds, as measured at
the Fairbanks International Airport, are from the east in winter and
summer and from east or west in spring and fall. The surface winds
are not strong, 2.3 m/ see average (Reference 3). The most striking
feature is the number of calms, especially frequent and long in winter.
Low level winds have been studied and measured in connection with
winter inversions and ice fog (Reference 3).

3. 1. 1.2 Temperature Inversions
Temperature inversions are frequent and steep in the Fairbanks
basin. Surface,inversions are present in more than 60% of all night
soundings the year round. During the dark months of December and
January, when diurnal changes in weather are virtually nonexistent,
surface inversions are present more than 80% of both day and night
soundings (Referel ce 3, page 7). The Fairbanks inversions are among
the steepest in the world (up to three times stronger than in Los Angeles).
Moreover, the fair banks inversions start usually at ground level, and
are extremely persistent, existing often for weeks at a time. Under
such extreme conditions, air pollutants tend to accumulate near their
emission sources and the sharply restricted air volume available for
their diffusion leads to high pollutant concentrations.
3. 1. 1. 3 Ice Fog
, Ice fog is formed when warm air carrying water vapor is inj ected
into the atmosphere at temperatpres below -3SoC (-31 of). The ability
of air to hold water vapor is decreased by three orders of magnitude when
the air temperature drops from 1000C to -3SoC (Reference 2). Ice
crystals form rapidly when combustion exhaust gases are injected into
the cold dry air because such gas contains abundant nuclei (small
particulates and ions). Breathing also causes ice fog to form, a'S does
water evaporation from heat rejected into river and cooling ponds. Ice
fog is formed by a plethora of small ice crystals of about 10 microns
diameter, which appears at temperatures below -3SoC in populated
regions where topography, combined with strong inversions, 'causes air
to stagnate (Reference ,2, page 1). Ice fog is not a pollutant according
to the National Ambient Air Quality Standards. However, its appearance
creates hazardous traffic conditions because of very low ("arm's length")
visibility and coincides with the long, steep temperature inversion
during which pollutants accumulate. High carbon monoxide concentra-
tions have been also detected during steep clear weather inversions,
indicating ice fog is not required for its accumulation. For example, a
CO concentration of 71 mg 1m3 was measured i~ April 1971 , on a clear
3-3

-------
o
day. The temperature on the ground was 20 F and the temperature
. >!<
inversion steep. " Thus, the highest concentrations do not necessarily
coincide with ice-fog formation. Reduced automobile traffic in ice-fog
may be one explanation. Lower carbon monoxide concentration on the
ground may be caused by temperature gradients in the first 10-20 meters
above the ground being reduced by the presence of the ice-fog; radiation
starts at the top of the ice-fog layer rather than at the ground, and slow
mixing currents increase diffusion of pollutants throughout the ice-fog
layer.
3. 1. 1.4 Precipitation
Annual precipitation in the Fairbanks region is fairly light
(t 2 inches). Rain showers begin in May and continue throughout the
summer with a maximum in August. Precipitation amounts decline
from September through the middle of December when snowfall increases
markedly and reaches a maximum in January. Snowfall continues
through March with persisten snow cover throughout the winter months.
April averages the lightest precipitation and also realizes the greatest
percentage of possible sunshine.
Freezing temperatures persist from the first of September through
mid-May. Ice-fog and adverse air pollution conditions frequently occur
with the extremely low temperatures during anticyclonic conditions.
These conditions may persist for several days. Ice begins running in the
Chena Slough at Fairbanks during October and remains frozen until the
breakup in early May.
3. 1. 2 Soil Characteristics
Examination of the geologic map of the Fairbanks Quadrangle
reveals that the city of Fairbanks is sitting on a "flood-plain alluvium"
band of soil. Immediately to the north of the city is a plain of perenni-
ally frozen silt streaked with reworked creek gravel river beds. To the
south, beyond the Tanana River, there are land slide debris and
abandoned flood-plain alluvium and coarse gravelly facies. Everyone
of the above described soild will produc'e an abundance of dust when dry

and exposed to wind. Ground cover does not grow back too readily in
a near arctic climate and, though the hills around Fairbanks are
forested, the lowlands are not.
3.2 PRESENT AIR QUALITY
The air quality data available for this region are discussed in the
Air Quality Surveillance System volume. The location of the major
point sources in the air quality control region is shown on Figure 3-2.
The resul~s of the air quality data evaluation are summarized and com-
pared to the NAAQS in Table 3-1.
Air quality data relating to SOX are considerably below the primary
and secondary standards. The NOX concentrations are also below
National standards. Primary standards are, however, exceeded for
suspended particulate matter and for carbon monoxide according to
measurements made in the central section of the city of Fairbanks. The
Air Quality Control Region is therefore classified Priority I for parti-
culates and for carbon monoxide.
The highest particulate and carbon monoxide concentrations were
measured in the Central Business District (CBD) of the city of Fairbanks.
However, the particulate concentrations measured at the Eielson AFB
guardhouse (22 miles southeast of Fairbanks) are also excessive. The
available air quality data are not sufficient to permit identification of all
sources of suspended particulates. The surveillance system described
in the Air Surveillance System Volume should provide information
necessary to identify more closely the sources of suspended particulates.
The high particulate and carbon monoxide concentrations measured
in the Fairbanks region are related to the topography, climate, wind
conditions and soil quality of the region, as well as to the man-made
stationary and mobile sources of pollutants identified in the emissions
inventory (Reference20). The influence of climate on man-made pollution
is particularly great under the extreme climate of this Borough.

Four years of suspended particulate data are available from. the
NASN Station in Fairbanks. These data are examined in Appendix 3 A
in an attempt to isolate the influence of wind, precipitation and
temperature on particulate concentrations and thus try to separate out
the natural background concentrations from the man-made emissions.
This attempt was not successful because the data are not sufficiently
detailed. Some salient features of the available data are relatively
low particulate concentrations in winter (75 to 100 p.g/ m3) illustrating
the combined effects of freezing temperatures, low wind speeds and
snow cover. Highest concentrations are found in September of about
400 JJ.g/m3, the result of very dry weather and high winds.

3.3 PROJECTED REGIONAL GROWTH
3.3. 1 Population Growth
Fairbanks is the second largest city: in the State of Alaska. It is
the sole trading center for a vast region and has a history of sharp but
short-lived population growth increases. The growth rate was high at
7 to 8% per year in the 1950 decade, corresponding to the buildup of
military establishments. Growth of about 2. 5% continued between 1960
and 1964. The population then stabilized around 41, 000 until 1968
(Reference 23 ). The Fairbanks area population was 60% of the tot~l
area population in 1969. The Labor Department projects continuing
growth at 3% per year for that region between 1969 and 1975. The
impact of the construction of an oil pipeline is not expected to be large
before 1975. Thus, a 12% growth between now and 1975 will be accepted
as a reasonable ground rule for emission rate increases of all sources
other than automobiles when calculating projected air pollution emissions
for 1975.
3.3.2 Potential New Point Sources
The establishment of the North Slope pipeline will constitute a
major industrial development in this region. In addition to the local
producing facilities, up to 12 pumping stations will be located along the
length of the pipeline. Pumping stations north of the Brooks Range will
be supplied with natural gas fuel. Stations south of the range will burn
high grade distillate fuel which will be either transported to the stations
or produced on site in a crude tapping unit. Pumping power will be
provided by gas turbines in either case. The sulfur content of the dis-
tillate oil to be used is below 0.2 % sulfur (Reference 7).
At design capacity, the crude tapping units will produce about
2,350 barrels of turbine fuel per day. Under normal conditions, off-
gases produced in the process will supply most of the fuel for the tapping
unit heaters.
A double chamber incinerator will be installed at each pumping
station for disposal of solid waste, including sludge from the tapping
plant. The maximum projected waste load for the station is estimated
to be 154 pounds per day. -

The estimated emission for such a pumping station~:' will consist of:

Nitrogen Oxides
Hydrocarbons
.44 tons/yr
460 tons/yr
750 tons /yr
575 tons /yr
550 tons /yr
Particulates
Sulfu r Dioxide
Evaporation losses from storage tanks will be minimized through
the installation of vapor recovery units as required by the proposed air
pollution regulations for the State of Alaska.
In addition to the oil pipeline, an oil refine ry and a rowe r plant are
also scheduled for construction in this area. The refine ry is to have
15,000 bbl /day throughput;:":, Depending upon the sulfur content of the oil
refined, SOX emissions without recovery could be as high as 1,500 tons
per year if fluid catalytic cracking units are used.
The power plant, to be integral with the refinery, will be rated at
626 x 106 Btu/hour and is scheduled to use refinery and/or fuel oil.
Uncontrolled particulate emissions could be of the order of 420 tons/yr
(23 lb/1, 000 gallons) and SOX emissions about 2,850 tons/yr (157 lb/
1,000 gallons at I % sulfur) if run on residual oil. The characteristics
of these sources are summarized in Tables 3-2. and 3-3.
3.4 EXISTING SOURCES OF AIR POLLUTANTS
Examination of the man-made emission sources, (Reference 20)
exclusive of traffic or climatologically generated dust shows that
transportation contributes about 10% of particulate emission and 85% of
carbon monoxide emission in Fairbanks (Reference20, pages 27 and 29).
Power plants are a major source of particulates and a very minor source

of carbon monoxide emissions. Automobiles are high carbon monoxide
emitters and contribute somewhat to particulate concentrations through
traffic produced dust.
3. 4. 1 Particulate Matter
The emission sources of particulate matter in the Fairbanks
North Star Borough can be classified into point sources, such as coal
burning power plants. and area sources consisting of smaller combustion
sources. dust generated through road traffic. wind. forest fires or
other phenomena having a large area distribution. These emission
source categories are discussed in the following sections.
3.4. 1. 1 Point Sources
The major point sources of particulate matter considered to have
an impact on the air quality of Fairbanks North Star Borough (sources 19.
28. and 38 listed for information purposes only) are listed in Table 3.4.
Those over 100 tons per year emitting particulates and CO are indicated
on Figure 3-2. Managers of aU "coal-burning sources were contacted by
questionnaire during the Emission Inventory effort and indicated that
they all use cyclones for emission control. Efficiencies reported
varied from 70 to 94% at 10 microns. For the purposes of the control
strategy. cyclone efficiencies of 84% are believed to be the maxi.mum
attainable and the numbers presented in the column "Actual 1970 Emissions"
reflect this efficiency. As indicated. the actual 1970 emission sources
(excluding airports) contribute about 6300 tons of particulate per year.
Though a projection of approximately 3% annual growh can be made for
civilian' sources. the phase-out of federal facilities, Fort Wainwright and
the Eielson AFB, could also occur in the near future thus affecting the
projection drastically. Transportation. other than aircraft. and area
sources such as re$idential burning of coal and open burning, are
estimated to account for an additional 750 to 1000 tons of particulates.
Forest fires are estimated to contribute around 10,000 tons of particulates
per year.

3.4. 1.2 Area Sources
Based on the atmosphere diffusion calculations the conversion of
coal-burning power plants to either natural gas or distillate oil would
also present a meaningful strategy for the control of particulate
emissions from these sources. Current plans call for a local refinery
at Fairbanks if the pipeline project is undertaken. This will result in
the availability of distillate oil for the power plants. In the case of .
natural gas, current plans call for the supply of such gas from the
North Slope oil fields to pumping stations up to the Brooks Range.
An extension of such a line to Fairbanks would mean an additional
200 miles of pipe. Although the use of distillate oil or natural gas
could potentially increase the emission of water vapor, thus increas- .
ing the ice fog density, the relative merit of such conversion should not;
be discounted, since the reduction of water vapor emissions can
probably be attained by technology under development. By con-
ducting a development program to define the r~quired design features
of a water vapor condenser, this problem could conceivably be solved
by 1975. The current experimental installation of such a device at the
facilities of the Bureau of Land Management in Fairbanks is a step in
this direction. Data from this installation will be available during this
winter and maximum use should be made of such results to ascertain
the operating characteristics of such a system.
The air quality data for Fairbanks has been discussed in pre-
ceding sections. Very high particulate concentrations have been
measured in the CBD. However, few samples have been taken (in
particular, few winter samples) and the inlet to the sampler for the
NASN measurements was only 3 feet off the ground on the busiest street
of Fairbanks. Better measurements are needed to fully evaluate the
extent of particulate pollution problems and especially its spatial
distribution. However, application of corrective measures must be
initiated now and the control strategies modified as needed between 1972
and 1975.
3-14

-------
. The very large seasonal variation in measured particulate concen-
trations indicate that the contribution of blown-in and traffic-generated
dust, and possibly open burning and forest fires is very large. The con-
tribution of forest fires to the particulate concentrations in the summer-
time is believed to be. significant. Shutdowns of the Fairbanks Municipal
Airport have occu rred on seve ral occasions because of a lack of visibility
resulting from distant forest fire smoke being blown over the city. The
magnitudes of these fires vary of course, but they do occur from April
through October.
Open burning for land clearing operations is yet another source,
perhaps a major source, of particulate emissions during the summer
season. Current regulations in the North Star Borough permit the clear-
ing of sm~lliand parcels (1/2 acre) by open burning. Permits are
required for larger fires. Judging by the large number of fire reports in
the files of the Bureau of Land Management, the number of large man-
made fires reported in the area are probably associated with land
clearing operations initially intended to be limited in size.
3.4.1.3
Traffic and Road Sources
Most of the streets in the CBD are paved as are the main access
roads. However, Figure 3-3 shows that the streets of the residential
section northeast and south of the CBD are unpaved. Tra.ffic in the CBD
is high, especially so in the summer as shown in Figure 3-4 The access
roads, which carry a great flow of traffic as shown on Figure 3- 5
have soft shoulders. In dry weather, the road surface outside the normal car
car tracks is dusty so. that cars cutting across lanes to pass or pulling
over onto the road shoulder raise a great deal of dust and the higher
their speed, the thicker the dust cloud.
In wet weather the dust is transformed into mud and transported
onto the city streets. Construction sites, street repairs and underground
utility installations are sources of tracked-in mud.
Projected improvements in traffic flow, resulting in accelerated
car flow may further aggravate the dust problem, unless steps are taken
to cope with it.

The streets in the Fairbanks CBD are cleaned every night during
the warm season, when the temperature is not so low as to freeze the
water in the sweepers. A wetting agent is added to the water to increase
its cleansing action. Residential sections in which the streets are paved
are cleaned on a rather irregular schedule (which is influenced by
complaints) .
In winter 3/8-inch chips are used on the icy streets and roads.
These chips are quartz rock cubes and do not disintegrate under the car
wheels. Oiling of unpaved roads starts after the thaw. Good quality
highly wetting oil is used. The schedule is not regular as road grading is
also necessary.
3.4.2 Carbon Monoxide
Carbon monixide emissions for Fairbanks are 35, 182 tons /year
(Reference20, page 10). Of this total 23, 323 tons /year are from gasoline
motor vehicles and 2,253 tons/year from diesel motor vehicles. The
remaining 10, 000 are fairly evenly divided between other sources. Point
source contribution is very small.
3.5 IMPACT OF EMISSIONS ON AIR QUALITY
The Area Model Estimation procedure (Reference 6) was used to
convert the emission rates into air quality - as was done for the Cook
Inlet Region (Section 2. 5). The estimation of air quality is highly
dependent on the choice of "urban area" on which the estimation is based.
Two reasonable choices were made and air quality calculations were
made for both (see Appendix 3B). These urban areas are the following:
1)
Area of a rectangle enclosing the city of
Fairbanks: 42 km2
2)
Area of an "air shed" (Figure 3 -6) bounded
on the north and northeast by the rdiges of
hills, on the west by Happy Creek and Chena
River, on the south by the Tanana River and
on the east by a north-south line ~elected to
include Fort Wainwright, 227 km .
A typical average wind velocity for this area of 2. 3 m/ sec was used
(Reference 3).

and
x
Thes e particulate concentrations are close to monthly geometric
mean concentration values measured during the winter months, 75 to
120 IJ.g/m3, shown on Figures 3A-1 through 3A-5.
Figure 3A-5 shows the 4-year average of the monthly geometrir
means (1 967 -1 970). The primary NAAQS c onc entrations of 75 IJ.g / m 3
are exceeded even in the winter months and soar above 400 IJ.g/m3 in
September.
3. 5. 2 Carbon Monoxide
Carbon monoxide 8 -hour average concentrations were calculated
usi~g the area model for city areas of 42 km2 and 227 km2 (Appendix' 3 B).
These areas correspond to the City of Fairbanks and the larger "air
shed" area, respectively. The concentrations were found to be

X = 4.2 mg/m3 (42 km2)

x= 1.6mg/m3 (227km2)
for an average wind speed of 2.3 m/sec. Measured values much higher,
81 mg/m3, have been observed by NASN. This calculation clearly
shows that the emission sources considered do not account for the
carbon monoxide problem.
A review of stationary sources showed that the very stable inver-
sion layer is so low that stacks protrude through the ceiling. Therefore,
emissions from these sources do not return to ground level, at least
not in Fairbanks.
A review of mobile sources, primarily automobiles, showed
several interesting facts. Because of the low ambient temperature,
. .

shoppers habitually leave their automobiles running while they are
in the stores. Further, workers start and run their automobiles
several times daily for about one-half hour so ~hat they will start easily.
3-20

-------
This continual running of automobiles results in very large quantities
of carbon monoxide being released. Then, because of the low inversion,
it is trapped in the city. The calculations of Appendix 2C show that 240/0
of the carbon monoxide generated by automobiles (on a yearly average)
is produced during idle. Automobiles are the primary source contribut-
ing to the high carbon monoxide levels.
Other potential sources of carbon monoxide were reviewed to
check on the conclusions of the previous paragraph. Eielson AFB con-
tributed essentially no carbon monoxide to downtown Fairbanks. The
inventory showed that mobile sources contributed 71 % or more of the
total CO to the downtown area. The other 25% is fairly evenly distributed
among six other contributors.

3.6 PROPOSED CONTROL STRA TEGY
3. 6. 1
Particulate Matter
The reasonably available control technology can reduce the 1970
emissions listed in Table 3-4 to approximately ,3470 tons per year, or
a reduction of 47%. This technology corresponds to 0.3 lb/million Btu
for coal burning power plants and 0.2 lb/ 100 lb of refuse for incinerators.
.These figures represent the suggested control requirements of the
Environmental Protection Agency and are delineated in Reference 6,
Appendix B. The requirements of the proposed Rules and Regulations
of the State of Alaska reflect even more stringent abatement to facilitate
the attainment of the secondary NAAQS. This requirement imposes a
limitation of O. 1 grain/sd which corresponds to about 0.2 lb/million
Btu. Appendix 3 -B shows this reduction will increase chances of the
attainment of the secondary national air quality standards and still
allow for a considerable contribution from other sources such as roads
and forest fires.
This stringent requirement is justified on the basis
that considerable contributions exist from road dust and forest fires.
The former is much more expensive to control while the latter is not
controllable at all in the conventional sense. The State regulations will
require particulate emission control of coal fired boilers of about 97%,
assuming typical uncontrolled emission rates of 7.4 lbs /million Btu.
A special study is proposed in the Air Quality Surveillance Volume
which will provide direct evidence as to the effectiveness of the control
of major coal fired installations in Fairbanks. The results of this study,
which will bp. available in July 1973, will be used to validate the control
specifications for these sources.
Prohibition of open burning and regulation of incineration are also
recommended control measures. These potentially, will reduce the
total particulate emissions in Fairbanks by 5300 tons per year.
Quantification of the impact of road paving, oiling and street and
road sweeping is not possible at this time (see the discussion on the
Anchorage area). However, it is known that dust is generated by traffic
on gravel roads and on paved roads and streets covered with tracked-
in dust. The following improvement schedule is proposed to be imple-
3-23

-------
mented in parallel with a data gathering and evaluation effort, and
modified in accordance with the findings of that effort.
Phase 1.
1972
] )
Paving Southwestern and Southern Residential Sections.
In summer, the prevailing winds are from the southwest,
so that dust from the Jones and the Bjerremark Subdivision
is most likely to be blown into town, where the particulate
concentrations are highest.
Implementation of this strategy will be accomplished by
negotiating with City and Borough officials to insure that
air pollution priorities are included in the normal road
improvement schedule.
2)
Increase Street Sweeping,. Increased operation of existing
street sweeping units will be undertaken with the daily
cleaning carried out on the central section of the cit y
extended to the heavily travelled streets designated for
soft shoulder oiling.
3)
Oil Soft Shoulders. A program will be initiated to apply
oil to the unpaved shoulders of 11 miles of arterial road
way.
The following roads are designated for oiling (4 times
during the 'period May through September) and daily street
sweeping: Airport Way, University Avenue, College Road,
Illinois Street, and South Cushman Street.
Phase II. 1973
Air quality monitoring data and the results of special studies
will be reviewed to determine the exact magnitude of the
suspended particulate problem and the effectiveness of the
control measures taken. Additional reduction of emission
levels may be required at this time.
If heavily tr~velled paved roads and streets are found to be
large contributors of suspended particulate, further increases
of street cleaning fequency and extension to more streets will
be necessary. If unpaved roads and streets are found to be
responsible for much of the particulate concentrations.
o
An extension of the paving program must be implemented
o
Increased oiling of gravel roads and of oiling of unpaved
shoulders on hard surface roads initiated,
Control of construction and land clearing operation to reduce
blown dust and tracked-in mud will also be considered.
The above strategy describes specific initial steps to be used in
reducing suspended particulate levels in the Fairbanks North Star Borough.
3-24

-------
Review of air quality and emissions data are essential steps in the
definition and implementation of strategy to achieve primary particulate
standards by 1975.
...
3.6.2 Carbon Monoxide
Maximum concentrations of carbon monoxide are found in the
central business district of Fairbanks under sharp temperature inversions,
low wind speed and low ambient temperatures. The maximum one hour
concentration measured of 81 mg/m3 and a one month average of I' .8
mg/m3 have been recorded. This data is limited having been taken at only
one site. Therefore the spatial expanse of these high concentrations is not
known. Evenso, the data does show a serious problem. A roll back calcu-
lation indicates that 50% (80 to 40 mg/m3) reduction is required.
, .
3.6.2. 1 Federal Motor Vehicles Program
Moble sources are the major contributor of .carbon monoxide
to Fairbanks. The Federal Motor Vehicles Program will reduce the
emissions rates from these sources. A reduction of 27% is expected
by 1975 and 45% by 1977 (Reference 7, Appendix I). These figures
apply to the average driver in the continental United States where the
climate is relatively moderate. Adjustments to these expected reductions
are required to account for the severe winter driving conditions occurring
in Fairbanks. A 35% reduction in emissions by 1977 is a more realistic
figure for the Fairbanks area.
3.6.2.2 Summary of Control Measures Considered
Extensive study was conducted to determine potential solutions
to the carbon oxide problem and many alternatives were evaluated. A
summary of the alternatives studied and rejected is given in Appendix
3C. Recommended control measures are described in the following
section.
3.6.2. 3 Recommended Control Measures
Plug - Ins - Installation of additional plug-in facilities was one of
the measures retained to be implemented. A p~ug-in is an electric
outlet (110 volts) located in the proximity of a parking space for auto-
mobiles. It permits the car owner to operate headbolt and circulation
heaters installed in the engine compartment. The heaters, having 1 to 2
3-25

-------
kw rating, keep the engine. warm for subsequent operation. Some cars
may have a heating plate under the battery and a space heater in the car
interior. The use of these plug-in facilities, therefore, would permit
quick startup in below zero weather without the necessity of extended
idling times. The advantages of plug-ins are their almost total elimination
of carbon monoxide emissions from idling, they are relatively inexpensive,
they could potentially pay for themselves, and they represent a savings to
motorist. The disadvantages are that they are effective only in cold
weather, they are difficult to install in existing parking areas and they
require an extensive electrical distribution system.
Parking spaces with plug-ins are rented by the month at a
premium. The normal rental fee is $20 per month on an annual basis.
The demand currently exceeds the supply for persons employed in the
center city. There are approximately 500 plug-in parking spaces today
in use by persons employed in the Center city, at high schools and at the
airport. No parking spaces are currently available for shoppers. It is
estimated that about one hour of idling is eliminated by the availability of
plug-in parking spaces per person employed in the center city area.
Staggered Work Shifts - Staggering the work shifts for the
downtown area has the advantages that it is a very effective measure
in reducing hourly peak concentrations, however, it may not effect
longer term averages. It smooths out traffic flow and reduces rush
hour traffic concentrations. A problem is that the exact effects on
air quality of staggered work shifts are not known.
Elimination of On-Street Parking - The advantages of eliminating
street parking is that it provides for an additional lane of traffic which
improves traffic flow - thus reducing emissions; eliminates excessive
circling of the block when shoppers look for on-street parking spaces,
which reduces emissions. However, alternative off-street parking
has to be provided in order to make this measure acceptable to down-
town merchants.
3-26

-------
Bypass Roadways - The advantages of bypass roadways are that
it eliminates many motor vehicle trips that would otherwise go through
downtown Fairbanks. The traffic diverted by the bypass would reduce
traffic volume through downtown and thus impro,:,"e traffic flow.
A bypass roadway is to be constructed in 1972 - 1973. It is
called Project F - 061-1 (6) Gaffney Road to Farmers Loop. It runs from
Gaffney Road (southern section of town) across the river and ties into
the Steese Highway (northeast section of town). This path can be
traced on the map of Fairbanks, Figure 3-6.
Bus System - The use of an extensive, permanent bus system for
Fairbanks including a terminal facility and waiting stations has been
considered but rejected because of high cost and the anticipated low
public acceptance. However, if the other strategies considered and
proposed in this plan do not result in the projected reduction of carbon
monoxide emissions, a bus system may have to be reconsidered as a
measure in spite of cost or public acceptance.
Though waiting for a bus
in extreme cold is not conducive to public acceptance of a bus system,
a system operated on a tight sChedule may gai~'1 public support.
Such
a system may receive additional reinforcement if one considers the
expense of running a car in the winter time in the Fairbanks area.
Improved Traffic' Flow. Carbon monoxide concentrations can also
be somewhat reduced by speeding up traffic flow. Carbon monoxide
emissions increase with reduced speed as well as with idling in traffic.
Traffic flow can be enhanced by increasing speed limits, or by use of
flexible traffic control, such as SAFER, in which traffic signals are
operated as CI. function of car density.

mental Conservation by June 1972.
1972-73
Conduct studies to determine the effect of the
following on CO concentrations: 1) staggered

3) traffic volume; 4) stationary source emissions
1973
The Gaffney Road to Farmers Loop bypass road-
wa y will be completed
1974
Continue any studies mentioned above if determined
necessary
1975
75% of all existing parking spaces will be equipped
with plug-in facilities

Elimination of on-street parking will be imple-
mented if determined necessary by the results of
the special study in 1972.
Expected Emission Reduction from Proposed Control Strategy. As
calculated in Appendix 3C, 76% of CO emissions are attributable to driving
and 24% are attributable to idling.
A 45% reduction of emissions from driving can be expected by 1977
from the Federal Motor Vehicle Program under normal operating condi-
tions. Since control of 1975 and later model year vehicles will rely
heavily on "no-choke" driving conditions, a 45% reduction may be too
optomistic for Fairbanks winter driving. Assume a 35% reduction from
the Federal Motor Vehicle Program to be more realistic for the driving
portion of CO emissions in Fairbanks.
The idling portion of CO emissions in Fairbanks will be controlled
by the limit on idling as well as the plug-in facili~ies,_. The regulations
will provide for a 63% reduction in excessive idling emissions by 1975
(Reference 7, Appendix C).
3-28

-------
Combining these percentages, the following total reduction may be
realized:
Driving:
35O/c expected reduction in 1977
weighted 76o/f! for driving = 26. 6O/c
Idling:
63o/f! expected reduction in 1975
weighted 24o/f! for idling = 15. 2o/f!
Total Expected
Reduction in Carbon
Monoxide Emissions: 26.6 + 15.2 = 41. 8
The bypass roadway is assumed to provide an additiona110O/c, .
therefore, the required 50O/c reduction will be achieved by 1977.

4. THE SOUTH CEN,TRAL ALASKA INTRASTATE AIR QUALITY
CONTROL REGION
4. 1 REGION DESCRIPTION
The South Central Alaska Intrastate Air Quality Control Region
constitutes those portions of the 1956 Election Districts 7 -17,

inclusive and Election District 24 described in Article XIV,
.,

section 3 of the Constitution of the State of Alaska, which are not
included in the designated Cook Inlet Intrastate Air Quality Control
Region as designated August 12, 1970.
This region encompasses a portion of Western Alaska, Southwest
Alaska (the Aleutians) and South Central Alaska. (Figure 4-1).
The region is sparsely 'populated with approximately 37,000 persons.
The major economic activities in this part of Alaska relate primarily
to the fishing industry. In addition, there are numerous military instal-
lations on Kodiak Island and the Aleutian Island chain.
4.2 PRESENT AIR QUA LITY
There are currently no air quality data in existance ,
for evaluation in connection with this study. Air quality measuring
instrumentation recommended for installation in this region is defined
in the Air Quality Surveillance Volume of this Implementation Plan.
4. 3 EXISTING SOURCES OF AIR POLLUTANTS
A summary of the major emission sources of particulate matter,

SOX and carbon monoxide (in exces s of 100 tons per year) identified

in the emission inventory are listed in Table 4-1. Roads are not
extensive; as a result, motor vehicle traffic is not a significant

contributor to air pollution. Approximately 41 million vehicle miles

are travelled in the region per year by approximately 5800 registered

vehicles. With the exception of King Salmon Airport and

Kodiak Electric, all major" sources are federal facilities, many of which
have diesel generators. The largest single source, the Kodiak Naval
Station, accounts for emissions as high as 1880 tons of S02 from its
power plant burning oil having a sulfur content up to 3.5%. It also burns
solid waste in the amount of 24,900 tons/year. In light of calculations
performed in Appendix D-l for sources of similar magnitude none of
these emissions appear to sufficient to result in violation of the
secondary national air quality standards. The compliance of these facil-
ities with the proposed Rules and Regulations for Air Quality for the
State of Alaska is expected to necessitate the use of fuel oil not exceeding
sulfur content of about 1 %, resulting in a 70% reduction of SOX emissions
at the Kodiak Naval Station.
4.4 POTENTIAL NEW SOURCES
In addition to several pumping stations (see S.ection 3.3.2 for typical
emiss.ions) along the north-south pipeline route in this Region, the terminal
for crude oil transport will be located at Valde z. Air pollutants will be
emitted at the terminal from fuel burning equipment and storage. The
estim:ated fuel burning equipment emissions, from diesel engines, fired
heaters and incinerators are as follows. (Reference 7)

A copper ore processing operation is projected for the McCarthy
area of this air quality region. It is estimated that approximately
5,000, 000 tons of ore per year will be proc,essed if the undertaking
materializes. The air emissions of such an operation depend on the
processes used, the abatement equipment installed and its efficiency.
The estimated characteristics of this source are summarized in Table 4-2.
The minimum controlled emission indicated represents the application of
reasonably available control technology while the maximum emissions
represent the use of low efficiency abatement equipment. As plans for this
installation become formalized the State of Alaska will, through the
Permit System~ coll~ct data n~cessa.ry for a comprehensive eva.lua.tio~
of the impact of thes e sources on air quality.
4.5 PROPOSED CONTROL STRA TEGY
No specific control measures are required for this AQCR since there
are no adverse air quality measurements or estimations.
Enforcement of statewide air pollution regulation and implemen-
tation of the permit system in which a comprehensive review of all
new source construction is made will provide for the maintence of
ambient pollution levels below the secondary NAAQS. The ambient
air quality surveillance system, proposed in this Plan, will allow
detection of air quality deterioration and provide the baseline data
upon which to plan industrial and population growth in the region.

5. THE SOUTHEASTERN ALASKA INTRASTATE
AIR QUA LITY CONTROL REGION
5.1 REGION DESCRIPTION
The Southeastern Alaska Intrastate Air Quality Control Region
includes those portions of the 1956 Election Districts 1-6, inclusive,
as described in Article XIV, section 3 of the Constitution of the State
of Alaska. The boundaries of the region are shown on Figure 5 -1.
The southeastern region consists of several major islands,
thousands of smaller islands, and a thin strip of mainland bounded on
one side by Canada and on the other by the Pacific Ocean. This land
area of approximately 30,000 square miles is similar in size to the state
of Maine. Ferries of the Alaska Marine Highway System serve to inter-
connect the major cities of the area. The only other modes of intercity
transportation involve scheduled airlines and small amphibious aircraft.
I
. The population is engaged primarily in fishing, lumbering, pulp
manufacturing, and tourism. The bulk of Alaska I s pulp and lumber
activities are in this area; forests of spruce and hemlock cover most of
the islands.
5.2
PRESENT AIR QUA LITY
There are no air quality data in existence for evaluation
in connection with this study. Air quality measuring instrumentation
recommended for installation in this region is outlined in the Air
Quality Surveillance Volume of this Implementation Plan.
5. 3 EXISTING SOURCES OF AIR POLLUTION
Major economic activity in this part of Alaska relates to industries
dependent on lumber. Two major pulp mills utilizing the sulfite process
are currently in operation. One of the mills, the Ketchikan Pulp Company,
is located at Ward Cove near the town of Ketchikan and the other, Alaskan
Pulp and Lumber, is located at Sitka. The se two mills are separated by

200 miles.
Considerable SOX emissions occur from lhese mills as a
result of process venting and the burning of Bunker C fuel oil (average
sulfur content 1. 3%). Particulate matter is also emitted as part of the
liquor incineration process.
Several lumber companies also operate in this region; among these
are Alaska Wood Products, Wrangell Lumber and Alaska Price Timber.
Lumber companies of this type dispose of major quantities of wood waste
through the use of large conical burners typically 40 feet in diameter and
60 feet in height. Wood waste is also used as boiler fuel to some extent.
As a result, these lumber companies are sources of particulate and
carbon monoxideemis sions.
A summary of typical emission rates for the significantly large
sources are indicated in Table 5-1. The SOX emissions of the boilers
at Alaskan Lumber and Pulp .are unknown and assumed to be the same
magnitude as that for Ketchikan Pulp because the plants produce the same
amount of product.
There are approximately 14,700 registered motor vehicles in this
region. There are no major highways and very few roads, and the aver-
age vehicle travels about 5250 miles per year.
Calculations were performed to establish whether ground-level con-
centrations of SOX and CO, and as appropriate, particulates, would
exceed the primary and secondary material air quality standards at loca-
tions downwind from the major sources in the Region. The details of
these calculations are presented in Appendix SA. A summary of results
is presented in Table 5-2.

5.4 POTENTIAL NEW SOURCES
There are three industrial operations currently proj ected for this
region. These consist of a pulp mill and two ore processing facilities.
The available details of these are summarized in Tables 5-3, 5-4, and
,
5- 5 showing potential emissions using reasona~ly available control
technology.
Although particulates represent the major air pollutant emis sions
from the ore processing facilities, the possibility of other air con-
taminants, especially fluorides, from the pelletizing and processing
operations must not be overlooked. As plans for these installations
become more definite the State of Alasks will, through the Permit
System, collect data necessary for a comprehensive evaluation of the
impact on these sources on air quality.
5. 5
PROPOSED CONTROL STRATE.GY
The emission reduction requirements which appear to be evident
in Table 5-2 are those relating to meeting the secondary national air
quality standards for SOX emissions from the pulp mills. In the case of
Ketchikan Pulp, pollution concentrations due to process emissions approach
the secondary standard within the accuracy of the calculations. When SOX
outputs from fuel burning are combined with the process emissions (all
emissions occur in close proximity), the secondary standard is exceeded
by a considerable margin. Alaska Lumber and Pulp indicates SOX pro-
cess emissions roughly half of that of Ketchikan Pulp, even though their
process rate is about the same. The reason is that the former is current-
ly not using all of its liquor. With the new water pollution regulations in
force, these lower emissions may only be temporary.
The process rate for both pulp mills is about 620 tons of dried
pulp per day. SOX emissions were assumed to correspond to emission
rates of about 30 pounds per ton of dried pulp based upon EPA factors.
Reasonable available control technology permits a reduction of such
emiSSiOns to 20 pounds per dried ton (Reference 27), a reduction
of 33%. This attainable reduction is reflected ill Table 5- 6 for
5-6

Ketchikan Pulp. Additionally, to meet the requirements qf the proposed
Rules and Regulations for Air Quality Control of the State of Alaska,
an emission rate of 500 ppm of SOX which corresponds to the use of
fuel oil will be limited to about a 1 % sulfur content (Section 7, Appendix
D-l). The net result of these reductions, indicated in Table 5- 6, will
provide for the attainment of the secondary standards. The attainment
of these reductions is projected for January 1975, in accordance with
the Compliance Schedule Volume.
The atmospheric diffusion estimates shown in Table 5-6 repre-
sent the maximum expected downwind groundlevel concentrations based
on a local wind speed of I m/ see and a Class D Stability category.
This stability category is characterized by limited horizontal and verti-
cal mixing and occurs frequently at night or under conditions of heavy
overcast. This estimate is believed to be a representative maximum for
ground level concentrations in this part of Alaska.
