PREFACE.
The Secretary, Department of Health, Education, and Welfare, is
directed by the Air Quality Act of 1967 to designate "air quality con-
trol regions" to provide a basis for the establishment of air quality
standards and the implementation of air quality control programs.
In
addition to listing the major factors to be considered in the develop-
ment of region boundaries, the Act stipulates that the designation of
a region shall be preceded by consultation with appropriate State and
local authorities.
The National Air Pollution Control Administration, DHEW, has CQn-
ducted a study of the New Jersey-New York-Connecticut urban area, the
results of which are presented in this report.
The Region* boundaries
proposed in this report reflect consideration of all available and per-
tinent data; however, the boundaries remain subject to revision suggest-
ed by consultation with State and local authorities.
Formal designation
will be withheld pending the outcome of that meeting.
This report is
intended to serve as the starting point for the consultation.
The Administration is appreciative of assistance received either
directly during the course of this study or indirectly during previous
activities in the New York City Metropolitan Area from the official
air pollution agencies of the City of New York and the States of New
York, New Jersey, and Connecticut.
Useful data was also supplied by

INTRODUCTION
"For the purpose of establishing ambient air
quality standards pursuant to section 108, and for
administrative and other purposes, the Secretary,
after consultation with appropriate State and local
authorities shall, to the extent feasible, within
18 months after the date of enactment of the Air
Quality Act of 1967 designate air quality control
regions based on jurisdictional boundaries, urban-
industrial concentrations, and other factors including
atmospheric areas necessary to provide adequate
implementation of air quality standards. The
Secretary may from time to time thereafter, as he
determines necessary to protect the public health
and welfare and after consultation with appropriate
State and local authorities, revise the designation
of such regions and designate additional air quality
control regions. The Secretary shall immediately
notify the Governor or Governors of the affected
State or States of such designation."
Section 107 (a) (2), Air Quality Act of 1967
THE AIR QUALITY ACT
Air pollution in most of the Nation's urban areas is a regional
problem.
Consistent with the problem, the solution demands coordinated
regional planning and regional effort.
Yet, with few exceptions, such
coordinated efforts are notable by their absence in the Nation "8 urban
complexes.
Beginning with the Section quoted above, in which the Secretary
is required to designate air quality control regions, the Air Quality
Act presents an approach to air pollution control involving closely
coordinated efforts by Federal, State, and local governments, as shown
in Figure 1.
After the Secretary has (1) designated regions, (2) pub-
lished air quality criteria, and (3) published corresponding documents

-------
HEW designates
air quality
control regions.
HEW develops and
publishes air
quality criteria
based on scientific
evidence of air
pollution effects.
HEW prepares
and pu blishes
information on
available control
techniques.
States hold
hearings and
set air quality
standards in the
air quality
control regions.
States establish plans for implementation, .
considering factors such as:

. Existing pollutant levels in the region
.Number, location, and types of sources
. Meteorology
. Control tech nology
. Air pollution growth trends

Implementation plans would set forth
abatement procedures, outlining factors
such as:
. Emission standards for the categories of
sources in the region.
HEW
reviews
State
standards.
. How enforcement will be employed to
i nsu re uniform a nd coord inated contr,)!
action involving State, local, and regional
authorities.
. Abatement schedules for the sources t~'
insure that air quality standards wili r.W
achieved within a reasonable time.
HEW reviews
State implementation plans.
States act to control air
pollution in accordance with
air quality standards and plans
for implementation.

on control technology and associated costs, the State(s) must file
with the Secretary, HEW, within 90 days a letter of intent, indicating
the State(s) will adopt within 180 days ambient air quality standards
for the pollutants covered by the criteria documents, and, within an
additional 180 days plans for the implementation, maintenance, and
enforcement of those standards adopted for designated air quality
control regions.
The new Federal legislation provides for a regional attack on
the problem and, at the same time, provides latitude for these region-
al efforts.
While the Secretary has approval authority, the State or
States involved in a designated region assume responsibility for develop-
ing standards and an implementation plan which includes administrative
procedures for abatement and control.
It is conceivable that an infor-
mal cooperative arrangement with proper safeguards will be adequate in
some regions, whereas in others, more formal arrangements, such as in-
terstate compacts, may be selected.
The objective in each instance
will be to provide effective mechanisms for control on a regional basis.
PROCEDURE IN DESIGNATION OF REGIONS
Figure 2 illustrates the procedure used by the Administration
in the designation of an air quality control region.
A preliminary
delineation of the region is developed by bringing together two es-
sentially separate studies -- the "Engineering Evaluation" and the
research into "Urban Factors."
To be successful, an air quality
control region must include jurisdictions capable of administering a

coordinated control effort, and the combination must include an area
large enough for a comprehensive attack on the problem of air pollu-
tion.
The study of urban factors provides insight on the nature of
the jurisdictions
and the engineering evaluation provides an indica-
tion of the geographical extent of the problem.
For air pollution that is truly regional in scope, air quality
control regions must be defined so as to include the majority of the
pollution sources contributing to the problem in an urban area and
must be extensive enough to encompass the majority of the population
and property affected by pollution emanating from the sources within
the area.
This requirement could be generally satisfied by individual
evaluation of the major factors -- the location, nature, and quantity
of pollutant emissions; present and projected patterns of urban develop-
ment; existing air quality levels; and prevailing air pollution meteor-
ology.
While separate consideration of these individual factors provides
useful insight on the nature of an urban area, it does not provide a
direct or dynamic indication of the extent of influence of sources in
an urban complex.
To supplement available air quality data, a constantly-evolving
technique referred to as diffusion modeling is employed.
Diffusion
modeling is a semi-dynamic process in which the air quality levels
at selected locations are estimated by calculating and adding to-
gether the weighted centribution from each of the sources, or groups
of sources, within the area under consideration.
As with most mathe-
matical simulation approaches, the calculations are repetitive and

-------
6
time-consuming, and so they are routinely carried out with the aid of
a computer.
These steps are outlined under "Engineering Evaluation" in Figure
2, and the box labeled "Input" describes the information required to
apply the diffusion model.
This information consists of data on the
nature and quantity of the pollutants being released and the physical
location of the sources, the average depth of air available for mixing
and dilution, the frequency of various wind velocities (direction
and speed) and the physical dimensions and topography of the urban
area under study.
The necessary calculations are made with this infor-
mation in the next step, labeled "Computer."
The result or "Output"
of the diffusion model approach is the estimated pattern of air quality
levels caused by the sources of a given pollutant within the area.
Because of the experimental nature of diffusion modeling, the results
are interpreted as theoretical.
After making necessary empirical
adjustments, "iso-intensity" lines (which will usually be closed,
irregulary-shaped contours of equal concentrations) can be developed
and presented in graphic or map form;
These graphs help establish
general geographical limits for the extent of influence of pollution
sources in a given area and, thus, serve as a guide to the necessary
size of the air quality control region.
The term "Urban Factors" encompasses all consicieratiolls of a
non-engineering nature.
Several examples are listed in Figure 2,
but many other factors are covered.
The existence and extent of
Standard Metropolitan Statistical Areas and Planning Areas of the

-------
7
Department of Housing and Urban Development are examples of some of
the additional factors that influence the final result in a given
region.
Based on the concept that, with some possible exceptions, it
is inadvisable to consider the inclusion of only part of a county in
a region, the study of urban factors results in a preliminary region
made up of the most reasonable combination of counties consistent with
the engineering evaluation.
The recommendation as to size and shape of the air quality control
region for the New Jersey-New York-Connecticut area and the supporting
documentation make up the body of this report.
The report itself is
meant to serve as the background document for the formal consultation
with the appropriate State and local authorities, and based on the
consultation, the Region boundaries proposed herein are subject to
revision within the discretion of the Secretary, HEW.
Following the
consultation, the Secretary will publish the final determination of
the Region in the Federal Register and will notify Governors of
New York, New Jersey, and Connecticut of his official designation.

DISCUSSION OF PROPOSAL
There are three major conditions to be met in designating an
air quality control region.
First, the boundaries should encompass
most pollution sources as well as most people and property affected
by those sources.
Second, the boundaries should encompass those
locations where industrial and residential development will create
significant air pollution problems in the near future.
Third, the
boundaries should be chosen in a way which is compatible with and
even fosters unified and cooperative governmental administration of
the air resource throughout the region.
The Evaluation of Engineering Factors (discussion beginning on
page 25) was directed toward the first of these conditions and the
Evaluation of Urban Factors (page 13), the other two.
A combination
of eight New York and nine New Jersey counties and twenty-one Connecticut
townships was common to all three of the stated conditions, leading to
the proposal made herein.
Taken separately, some of the factors considered suggested the
inclusion of a few jurisdictions bordering those proposed here.
As
discussed in the Evaluation of Engineering Factors, the major impact
of pollution sources located within the proposed Region is also within
the Region, with the following exceptions:
(1) known or theoretically
predicted SOX levels of concern extend into small portions of Mercer
County, New Jersey, and Suffolk and Orange Counties, New York; and
(2) known or theoretically predicted CO levels of concern encompass all of
Putnam County and part of Suffolk, Orange, and Dutchess Counties in

-------
11
New York, and New Haven and Litchfield Counties in Connecticut.
Yet,
the Evaluation of Urban Factors provided sufficient reason to rule
out serious consideration of all but one of the above-named juris-
dictions, the exception being Suffolk County, New York.
Orange,
Putnam, and Dutchess Counties in New York and Litchfield County in
Connecticut are essentially non-urban areas. Mercer and New Haven
have substantial populations and industrial activities but they are
more intimately involved in other centers of regional activity.
With respect to Suffolk County, the Evaluation of Urban Factors
brought to light conflicting considerations.
The majority of the
county's almost one million inhabitants reside in the western portion
of the county.
This, together with the results of the engineering
analysis strongly suggest that at least a portion of the county is as
subject to inclusion in the Region as some parts of the jurisdictions
proposed here.
However, a decision to bring the affected portion of
Suffolk County into the region, coupled with a desire to maintain the
entity of whole counties, might increase the size and nature of the
Region to a degree that would make a regional attack on the problem
of air pollution more difficult.
For this reason, Suffolk County has
not been proposed for inclusion at this time.
Comments received
during the consultation on this proposed Region from officials of
New York and of Suffolk County itself will have direct bearing on
the final disposition of Suffolk County in this regard.
As is true of most efforts to draw boundaries around an area to
differentiate it from its surroundings, there is always a likelihood

-------
12
of boundary conditions existing or developing.
In the case of air
quality control regions, such a boundary condition would exist where
there are sources of pollution on one side of the region boundary
affecting in some real way air quality on the other side of the
boundary. Relocating the boundary would only rarely provide relief
from this condition (especially along the urbanized East Coast).
The
solution is to be found in the way in which control efforts are imple-
mented following the designation of an air quality control region.
Consonant with the basic objective of providing desirable air quality
within the problem area being designated as an air quality control
region, the implementation plan that follows the designation should
have provisions for the control of sources located close to but beyond
the region boundaries.
The level of control for such sources would
be a function of, among other factors, the degree to which emissions
from such sources cause air quality levels to exceed the standards
chosen for application within the air quality control region.
The remaining two sections of this report describe the initial
evaluation of urban and engineering factors.
Each is, as much as is
possible, independent of the other--both with respect to subject and
conclusions.
As this discussion has indicated, the final proposal
is based upon both studies where there was agreement between them
and upon the balancing of the two where the two had differing con-
clusions.
The Region proposed herein is considered on the whole to
be the most cohesive and yet inclusive area within which an effective
regional effort can be mounted to prevent and control air pollution
in the three-State urban area surrounding New York City.

EVALUATION OF URBAN FACTORS
The New Jersey-New York-Connecticut interstate area constitutes
the largest urban center in this Nation by almost any criteria.
It
also lies at the heart of the so-called megalopolis which stretches
from Portland, Maine, to Norfolk, Virginia.
This region will, there-
fore, be one of the most important air quality control regions desig-
nated.
A large number of jurisdictions were considered for inclusion in
the Region.
Jurisdictions participating in the New York-New Jersey
Abatement Action, conducted recently by this Administration, were
taken as the natural core of the Region.
This section of the Report
presents an evaluation of the urban character of jurisdictions bordering
the core area.
The evaluation points toward the combination of juris-
dictions thought most capable of administering a coordinated control
effort.
The most significant potential addition to the l7-county* area
covered by the Abatement Action is a portion of the State of Connecticut.
The State of Connecticut, or specific portions of it, are intimately
involved in many activities centered in and around New York City.
The
Department of Housing and Urban Development has designated the Tri-
State Transportation Commission, which includes a portion of Connecticut,
as its official planning agency for this interstate area.
Perhaps most

County, Essex County, Hudson County, Middlesex County, Monmouth
County, Morris County, Passaic County, Somerset County, Union County

-------
14
importantt there is no clear break between the New York-New Jersey
urban concentration and the heavily populated and industrialized
portion of Southwestern Connecticut.
Inclusion of a portion of Connecticut gives rise to some special
problems.
Connecticut does not normally utilize counties as admin-
istrative units.
This being the case, it is necessary to select
another jurisdictional unit as the basis for Region boundaries within
that State.
The most obvious unit is the township; however, townships
are of such limited geographic area that it seems desirable to decide
upon some method of combining them into functional units when desig-
nating regions.
Perhaps the most useful combination of townships
currently operational are the planning regions defined by the Connecticut
Development Commission.
These planning regions provide a useful
method of utilizing established cooperative arrangements between town-
ships in each portion of the State.
While counties do not function as administrative unitst they are
used for some data-gathering purposes and serve as the basis for many
informal working relationships.
It, thereforet is desirable to combine
planning regions so that they approximate the boundaries of Connecticut
counties.
The Connecticut County bordering the New York-New Jersey
urban area is Fairfield County.
Three planning regions--the Southwestern,
Greater Bridgeportt and Housatonic Valley planning regions--include
all the townships in Fairfield County with the exception of the
townships of Sherman and Shelton.
They do not extend beyond the
borders of Fairfield County.

-------
15
New Haven County, lying immediately to the East of Fairfield
County, contains urban-industrial concentrations at New Haven,
Waterbury, and the Derby-Ansonia area, but they are not nearly as
closely tied to the New York-New Jersey urban area.
Litchfield
County, immediately to the North, is one of t~e least industrialized
and most sparsely populated counties in the State.
If it was decided
to include portions of Connecticut beyond the borders of Fairfield
County, it would be difficult to find combinations of planning
regions which approximate county boundaries and at the same time,
include jurisdictions that could be rationally linked to the New York-
New Jersey interstate area.
Several New York counties bordering on the eight counties included
in the Abatement Action area were also evaluated for inclusion in the
Region.
Suffolk County is the jurisdiction most similar in nature to
the counties of the core area.
This county has approximately one
million inhabitants and had the third highest growth rate in the
Nation during the last eight years. 1
The population projections in
Table I indicate that this growth rate will continue through the
coroming years 80 that, by 1985, Suffolk County will probably become
the third most populous county in the New York metropolitan area.
Housing starts in Suffolk County, a further indication of population
growth, are shown in Table II to be significantly above the rate of
any other suburban county under consideration.

Mitigating against the inclusion of Suffolk County is its size.
Suffolk is so large that a majority of its land area is beyond the
densely populated and heavily industrialized concentration, and it
extends eastward to the Connecticut-Rhode Island boundary.
Further,
present growth projections indicate that a suburban growth pattern
will probably develop for Suffolk County which may be basically devoid
of major heavy industrialization.
A second New York county considered for possible inclusion in
the Region is Putnam County which borders the core area on the north.
Putnam County is perhaps the most sparsely populated county in the
Tri-State area.
As can easily be seen from figures 4, 5, and 6, it
has less developed land and practically no industry as well as having
few areas of population concentration.
Further, its projected growth
suggests no major changes in its present configuration.
It is usually
considered as a recreation and forest area.
Much the same information applies to Orange and Dutchess Counties.
While major population centers do exist, these cities are surrounded
by open space.
They are also considered to be largely autonomous
from the urbanized complex surrounding New York City.
The counties in New Jersey bordering on the nine counties of
the Abatement Action area, with the exception of Mercer County, con-
stitute the rural counties of that State.
All but Mercer have few
built-up areas and even counties with urban centers have rather low
overall population densities.
Any industrial sources of pollution
could probably best be handled on an individual basis and not through
a broadly based regional approach.

Mercer County is heavily built up and contains significant
industrial concentrations.
However, many commercial indicators2
suggest that it is closely tied to the Penjerdel area surrounding
Philadelphia and might best be considered for inclusion in a region
developed for that area.
Appendix C contains additional data on urban factors in the
New Jersey-New York-Connecticut interstate area.
In that appendix,
data is arranged in tabular form to provide a well-organized summary
of quanitiative information relevant to designation of the Region.

SUMMARY
All available information on current measures of urbanization
suggest that there are eight counties in New York, nine counties
in New Jersey, and all but a small portion of one county in Connecticut
that share common characteristics; the counties are:
in New York--Kings,
Bronx, Nassau, New York, Queens, Richmond, Weschester, and Rockland;
in New Jersey--Bergen, Essex, Hudson, Middlesex, Monmouth, Morris,
Passaic, Somerset, and Union; and in Connecticut--Fairfield.
The
characteristics that they share--heavy urbanization, related patterns
of expected growth, interdependence of dwelling and employment locations,
and cooperative regional planning--make these 18 counties (located in
three States) a logical choice to serve as at least the core of an
air quality control region.
At the same time, there is (with three
exceptions) enough undeveloped land in and beyond the outermost of
these 18 counties to provide a "buffer" for future growth.
The
exceptions are:
(1) Mercer County in New Jersey; (2) Suffolk County
in New York; and (3) New Haven County in Connecticut.
Both Mercer and New Haven counties are well populated and
industrialized, but neither of them are closely related to the New
York urban area socially, commercially, or governmentally.
Mercer
County is more closely tied to the combination of, jurisdictions which
looks to Philadelphia as its economic, cultural, and social center.
New Haven is an autonomous urban area in South-central Connecticut.
These two counties could be ruled out of the New York-New Jersey-
Connecticut Region on this basis.

-------
24
Of the three exceptions mentioned, Suffolk County in Long Island
presents the only real difficulty.
Population densities range from
10,000,per square mile in the western part of the county to less than
100 people per square mile in the eastern portion.
The county is
approximately 85 miles long and essentially parallels the entire
sea coast of the State of Connecticut.
While Suffolk County has relatively
few large sources of air pollution when compared to the other counties,
it is presently the sixth most populated New York county in the area,
and is projected to rank third by 1985.
The final determination on
Suffolk County should weigh the need to provide e large suburban
population protection from and a voice in the control of regional air
pollution against administrative difficulties that might be generated
by the inclusion in the Region of such a large and diverse county.

ENGINEERING EVALUATION
The engineering evaluation was based on studies of pollutant
emissions, meteorology, available ambient air quality data, and
air quality levels as determined on the basis of diffusion model
calculations.
With the exception of the diffusion model results,
the two major sources of data were the technical report for the
New York-New Jersey Air pollution Abatement Activityl, and Air
Pollution Measurements of the National Air Sampling Network.2
The Abatement Action emission inventory included estimates for
three major pollutants--sulfur oxides, carbon monoxide, and suspended
particulates for the New York and New Jersey portions of the three-
1
State urban area.
The results of that work are summarized on an
annual basis for major jurisdictions and source categories in Tables
A-2 through A-4 in Appendix A.
Table A-5 presents similar results
for the three major SMSA's in southwestern Connecticut.
The estimated
annual emissions of each of the three pollutants were then converted
to average or mean daily emissions for three different time periods--
annual, winter, and summer--by apportioning according to heating-degree

days those emissions that vary as a function of heating season;3
ilie
results (Table A~6 in Appendix A and Table III) served as the basis of
the diffusion model calculations.
The pattern of sulfur oxides, carbon monoxide, and particulate
emissions and the resultant concentration patterns provide a good
measure of the general geographical extent of the overall problem.
The estimate of sulfur oxide pollution levels illustrates the impact

of fuel burning activities at private and commercial sources, or govern-
ment-owned power plants.
Carbon monoxide pollutant levels provide the
best indication of the impact of gasoline-powered motor vehicles on
4
the regional air pollution pattern since over 95 per cent of all
carbon monoxide emitted in the New York City metropolitan area comes
from motor vehicles.
Diffusion model estimates of suspended particulate
levels provide the best measure of the combined impact of all source
categories, since, of the three pollutants covered in the emission
inventory, particulate emissions are the most evenly distributed by
source category (no single source category accounts for more than 29
per cent of the total--see Tables A-2, A-3, and A-4).
There are
undoubtedly, other pollutants that on occasion will have different
dispersion patterns, but the three used here are considered to ade-
quately reflect the "average" geographical extent of the problem.
By estimating the patterns of dispersion of these three major
pollutants, the diffusion model technique provides a guide as to a
possible minimum boundary for the region but does not dictate the
exact boundary location.
By way of example, significant levels of
one or more of the three pollutants extending into a county contiguous
to the major urbanized area would indicate that that county is being
subjected to a pollutant load that constitutes a part of the total-ar.ea
problem.
This county, then, should be considered for inclusion in the
air quality control region, but the final decision will be based on
joint consideration of this as well as the non-engineering evaluation.
Average emission densities for each of the three pollutants in
tons/sq. mi./ day were determined by relating the total quantity of

-------
28
pollutants emitted in each of the reporting zones for average space-
heating-day conditions to land area of each zone.
The resulting emission
densities are presented graphically in Figures 7, 8, and 9.
The
general pattern of emission densities for each of the three pollutants
is closely related to the pattern of urbanization in the central
portion of the New York-New Jersey area.
The highest emission densities
occur in or close to the Manhattan area, but the density pattern in
each case extends well into Queens, Brooklyn, and the Bronx in New
York, and into Hudson, Essex, Union, Bergen and Middlesex counties in
New Jersey.
DIFFUSION MODEL RESULTS
While the geographical distribution of pollutant sources
illustrates clearly the core of the air quality control region, it
does not, by itself, provide complete insight as to the extent of
influence of the combined sources on the people and property located
outside the highly urbanized portion of the greater New York City
metropolitan area.
A study of air quality levels known or estimated
to occur is useful in determining the area affected by the pollution
sources and thus subject to inclusion in the air quality region. Such
analysis can be based directly on air quality sampling data in those
instances where the sampling program covers a large-enough area and
has been in existence long enough to provide reliable patterns of
air quality throughout the region under study.
Such air quality data
rarely exists, and it becomes necessary to develop estimates of prevailing
air quality.
The diffusion model is the technique by which such

estimates are made on the basis of information on pollutant emissions,
meteorological conditions, and the physical character of the urban
complex.
The diffusion ~odel used in this study and the results obtained
are covered in detail in AppendixB and summarized briefly below.
The model is based on the long-term Gaussian diffusion equation,

described by Pasquil15 and modified in recent years6, 7 for application
to the multiple-source situation of an urban area.
The basic equation
assumes that the concentration of a pollutant within
a plume has a
Gaussian distribution about the plume centerline in the vertical and
horizontal
directions, with the standard deviations in the two directions
being a function of distance from the source and certain characteristics
of mixing layer, collectively referred to as "stability class."
Graphs
have been developed which give U-z (vertical) andUj (horizonal) diffusion
coeffiecients versus stability class and distance downwind.
Reference
5 describes the Gaussian-based diffusion model and the inherent
assumptions made when it is applied.
The diffusion model was applied for each of the three pollutants
for the three different time periods--annual, winter, and summer.
Figure 10and Table IV show the meteorological data required to apply
the model for each of the three time periods.
Figure 10 shows the
percent frequency of occurrence of wind direction from 1951 through 1960
at John F. Kennedy Airport for summer, winter, and annual conditions.
The wind rose data (speed and direction) for JFK Airport were used in

represents (for long-period averaging) prevailing wind patterns through-
out the area.
The mixing depths for the time periods are an average
of the mean daytime and mean nighttime values as shown in Table IV;
these data were obtained from the National Weather Records Center
(ESSA).
Combined with wind data, these data are used in the diffusion
model to assess the spatial distribution of pollutant concentrations
on the 16 points of the compass.

Using the foregoing information on emissions and meteorology,
concentrations were calculated for each of the three pollutants for
each of the three time periods at a total of 97 ground-level receptor
points (20, 30, 40, 50, 70, and 100 kilometers from an assumed center
point located in Central Park, Manhattan, at each of 16 compass points,
plus a calculation of the concentration of the center point itself).
The theoretical concentrations estimated by this process are in addition
to "background" levels since the model was not supplied with information

-------
35
on sources located outside the area initially surveyed.
The results
are presented in Figures B-1 through B-13 in Appendix B as theoretical
- "
concentrations and are discussed in greater detail below.
SULFUR OXIDES
Figures B-1 through B-3 in Appendix B show the results of the
theoretical model calculations for SOx.
Actual sampling data suggest
that the model over-estimates concentrations of this pollutant by a
factor of 3-4 (Figure B-2), in part because no allowance was made for
SOx decay (the reaction of SOx in the atmosphere into other sulfur
compounds).
Figure 11 was produced by applying a "decay factor" involving
a 3-hour half-life to the initial output of the model.
Figures B-5
and B-6 in Appendix B show resulting contour lines after decay factors
involving 6-hour and l2-hour half-lives, respectively, were arbitrarily
selected for analysis.
The result incorporating the 3-hour half-life
was chosen for discussion here because the results, though still
theoretical, gave the best correlation with sampling data.
Comparison
of the diffusion model contours and the available monitoring data
in Figure 11 show the estimates fall well within a factor of two of the
measured concentrations.
Concentration contours are presented in Figure 11 down to a
concentration of 0.01 ppm.
This has been pointed out as the average
annual concentration at which human health begins to show signs of
deterioration; it is also assumed that this level is close to the
background level in highly urbanized areas.

concentrations for the three seasonal conditions are presented in
Figures B-3 through B-10 in Appendix B.
The results for an average
summer day are discussed here since, of the three seasons considered,
this gave. the highest theoretical results.
Aerometric data from seven
stations plotted on Figure B-9 indicate that the model routinely
estimated concentrations 2-11 times lower than those reported at actual
sampling sites.
For the purpose of showing the. relative distribution.
of CO levels, the model estimates are adequate; but choosing a cut-off
level that has relevance in terms of those values routinely reported
. . . -
from sampling is difficult because of the 2-11 factor mentioned above.
The diffusion model does not reflect the built-up nature of the area in
which most of the CO is emitted and thus assumed that the pollutant
has more immediate space and volume within which to disperse.
Until
the air into which the pollutant is being emitted moves away from the
built-up part of the urban area, the pollutant is channeled through
streets and around buildings.
This fact is assumed to cause some of
the discrepancy between estimated and measured concentrations of CO.
Also, it is recognized that most CO measurements were made at judiciously
selected locations (e.g., near highways, shopping centers, etc.) which
would be expected to yield higher concentrations than theoretical
average values.
Based on the 2-11 difference, an
average factor of 4.5 was
derived and applied to the theoretical diffusion model estimates to
give "adjusted" CO concentrations.
In so doing, the relative
distribution of CO levels calculated by the model is preserved, while

-------
38
the finite values assigned to the contours are brought more into line with
actual sampling results.
The resulting CO level estimate is shown in
Figure 12.
Theoretical contours have been plotted for 4, 3, 2, and 1 ppm
of the pollutant.
1 ppm of CO is assumed to be close to the background
level in most highly urbanized areas; this value at the outskirts of
an area, then, might be used as a starting point in defining the area
affected by sources within the Region.
SUSPENDED PARTICULATES
The diffusion model estimates of theoretical suspended particulate
concentrations are less than ideal for two reasons:
1) they do not
include an allowance for background concentrations; and, 2) they are
based on an emission inventory that estimates total particulate emis-
sions, and therefore, no deposition term is applied.
The first would
cause the model estimate to be lower than measured concentrations, and
the second would cause the estimate
to be higher than measured con-
centrations of suspended particulates.
Theoretical results are compared with aerometric data for 13
stations in New York and New Jersey in Table V.
The theoretical
values were, on the average, 0.60 of the measured results.
When this
factor was applied to the diffusion model contour lines, the "adjusted
theoretical" contour lines of Figure 13 resulted.
Two methods were utilized to analyze the particulate contours shown
in Figure 13.

areas surrounding the New York City urban complex, the area enclosed
by this contour line might be considered the area most affected by
particulate emissions in the New York City metropolitan area.
Relative
values of particulate concentration are shown in Figures 14 and 15.
The "relative concentrations" are plotted versus location along the
two major axes (north. south, east-west) and along the northeast-
southwest axis.
Shown also are the boundary locations along the axes
for the jurisdictional entities.
The relative impact of pollution
emissions within the New York City metropolitan area becomes less
significant with increasing distance outward from the Central Park
reference point.
The slope towards the bottom portion of each curve
approaches zero, thus pointing out approximately where the impact of
-the sources within the region begins to lose significance in the
outlying areas.

SUMMARY
The 0.01 ppm SOx contour line includes all or most of the land
area in the following counties:
nine counties in New Jersey--Passaic,
Morris, Somerset, Middlesex, Monmouth, Essex, Bergen, Hudson, and
Union; eight counties in New York--Manhattan, Bronx, Queens, Kings,
Richmond, Nassau, Westchester, and Rockland; and Fairfield County in
Connecticut.
The line also includes small portions of Mercer County,
New Jersey, and Suffolk and Orange Counties, New York.
Enclosed by the 1 ppm CO contour line are the same nine counties
in New Jersey, the same eight counties plus Putnam County in New York,
and Fairfield County, Connecticut.
The 1 ppm contour line also in-'
cludes small portions of Orange, Dutchess, and Suffolk Counties in New
York, and of New Haven and Litchfield Counties in Connecticut.

The 40~g/m3 contour line for particulates encompasses most or

all of Hudson, Union, Essex, and Bergen Counties in New Jersey, and
Manhattan, Bronx, Richmond, Queens, Kings, and Nassau Counties in New
York.
Partly included counties are Monmouth and Middlesex Counties in
New Jersey, Rockland, Westchester and Suffolk Counties in New York, and
Fairfield County in Connecticut.
The relative concentration curves indicate that particulate pollu-
tion emanating from within the area covered by the emission inventory
tends to become significant at the outer edge of Morris County to the
west and Suffolk County to the east, at the outer edge of Monmouth to
the south and Putnam County to the north.
Similarly, the NE-SW con-
centration profile shows that the relative impact is insignificant

-------
at the outer edge of Middlesex County to the southwest and Fairfield
County to the northeast.

APPENDIX A.
EMISSION INVENTORY PROCEDURE
The recent emission inventory as part of the New York-

New Jersey Air Pollution Abatem~nt Activityl provided the information
on emissions necessary to study the area prior' to the designation
of an air quality control region.
Data for New York and New Jersey
were compiled during a 3-month period from June through August, 1966,

for SOx and CO, and f;rom February to October, 1967, for particulates.
Data for Connecticut are also for 1966 and were obtained through
personal communication with the State of Connecticut.
The Pub lic
Health Service2 and the New York State emission inventory procedures
were employed with some modifications.
The emission inventory
.consisted of evaluating the consumption of gasoline, diesel fuel,
coal, fuel oil, and natural gas and of determining emissions from
refuse incineration and process industries.
Emissions were
determined directly from the fuel input to the equipment for both
Emission factors3 and sulfur
automotive and stationary sources.
contents are listed in Table A-I.
These factors were used wherever
more specific information was not available.
Annual consumption of all fuels, process emissions, and
incineration emissions were determined for each zone in the
New York-New Jersey portion of the study area.
Tables A-~ through A-~ summarize the estimates of annual
emissions of sulfur oxides, carbon monoxide, and particulates by
source category and political jurisdiction for New York and New
Jersey.
Less complete data are shown in Table A-5 for Connecticut
by SMSA.

The emission data were converted to show mean-day emissions
for annual, winter (December, January, February), and summer
(June, July, August) seasons (Table A-~) to facilitate diffusion
model calculations of mean-day concentrations for each of the three
seasons.
The conversion was accomplished by apportioning variable
emissions to each of the seasons in accordance with information on
monthly heating-degree days and then calculating the average-day
emissions for each season.

APPENDIX B.
DIFFUSION MODEL DESCRIPTION AND RESULTS
Title I, Section 107 (a) (2) of the Air Quality Act of 1967
(Public Law 90-148, dated November 21, 1967), calls for the
designation of air quality control regions, based on a number of
factors, including "atmospheric conditions", interpreted to mean
that the boundaries of air quality control regions should reflect
the technical aspects of air pollution and its dispersion.
Within
this guideline, however, the position has been taken that region
boundaries cannot be based on an extreme set of circumstances which
might have a theoretical chance of occurence.
Hence the analysis
of a region's atmospheric dilution potential is largely based on
mean annual values, although summer and winter mean values are
analyzed with respect to reviewing seasonal variations in meteorology
and pollutant emissions.
With the realization that the meteorological analysis would
help define tentative boundaries only and that final boundaries
would be developed subsequently to reflect local government aspects,
it was decided that the meteorological assessment should be as
unpretentious as possible.
Accordingly, the widely accepted long-term
Gaussian diffusion equation, described by Pasquilll, has been applied
with a few modifications to accomodate certain requirements inherent
to the delineation of air quality control regions.
These modifications
are discussed in the next section.
In summary, the Gaussian diffusion
equation is utilized to provide a theoretical estimate of the

-------
58
geographical distribution of long-period mean ground-level
concentrations of SOx, CO, and suspended particulates.
The model
used has the necessary flexibility to utilize information on
emissions from both point and area-wide sources.
To maintain simplicity, all pollutant sources were assumed to
be at ground level; for CO this assumption is realistic.
The s~e
assumption is used for major point sources of SOX and particulates,

since the distances of interest are sufficiently great to obviate
the source-height effect for most receptors.
Also, since there
is no agreement to what an appropriate half-life and deposition
rate for SOx and particulates, respectively, these factors were
not applied to the computations of ground-level pollutant concentra-
tions during the initial diffusion model analysis.
As discussed
earlier in the report (page35) and briefly below, certain modifications
have been applied to the theoretical model results to allow
comparative interpretation.
METHODOLOGY
The diffusion model used to compute theoretical long-term
average pollutant concentration distributions for respective pollutants

is based on Pasquill's Gaussian diffusion equationl, as modified by
M . 2
art~n .
Essentially, the diffusion model sums the effects (ground-
level concentration) of a number of sources (area and point) for a
specified number of receptors, averaged over a season or a year; the
receptor points are at distances of 20,30,40,50,70, and 100 kilometers

-------
from a defined central grid point for each of i6 compass directions.
AIl. average pollutant concentration is computed for the central grid
receptor (designated in the downtown or central city area) for
comparison to air quality measurements that might be available.
The meteorological data input to the model is screened to.
determine the representiveness of the data.
Appropriate surface
wind rose data are selected from U.S. Weather Bureau records; if
necessary, special wind data tabulations are obtained from the
National Weather Records Center (NWRC)o
The mean mixing depth for
each region, for each respective time period (seasonal and average),
is determined on the basis of computed mixing depths documented by


HOlzworth4,5 and recent tabulations furnished the Meteorology Program
by the National Weather Records Center (ESSA).
RESULTS
A comparison of calculated concentrations of CO to air quality
data for the New York City metropolitan area shows reasonable
agreement in relative ~, but the model consistently underestimates
the concentration in comparison to measured values in the central
urban area6.
As is discussed in the text of this report, an
empirically derived correction factor has been applied to the output
to allow comparative use of the CO data.
For SOX the initial model calculations were systematically higher
than measured calculations.
This over-calculation is thought to
result from the fact that SOX reacts in the atmosphere, leading to
59

-------
60
concentrations lower than those predicted by the model.
As discussed
in the body of this report, three "decay factors" representing
arbitrary half-life assumptions of 3, 6, and 12 hours have been
applied to the ~heoretica1 model output to aid in the analysis.
For suspended particulates, the model gave relatively good results
when the finite values were compared to measured concentrations in
and around the center of the proposed New York City region.
The
good correlation seems to be the result of two apparently compensating
limitations of the model.
The model estimates for suspended particulates
are also interpreted in this report in a relative sense.
Figures B-! through B-~ present unmodified SOx results for the

,three time periods and, B-~ through B-6, SOX results as modified by
three half-life assumptions.
Figure B-1 shows theoretical 0.01 ppm
contour lines for SOx for the three half-life assumptions.
Figures
B-~ through B-13 show diffusion model results for CO and suspended
particulates for the three time periods investigated.
The model results can be appropriately modified and interpreted
to provide reasonable spatial distributions of long-term (seasonal
and annual averages) pollutant concentrations resulting from the.
release of pollutants within a region.
