                                 ABSTRACT
     This project provides a disaggregated particulate matter and sulfur
dioxide emission inventory suitable for use in both base year and projec-
tion year modeling required for the Capital District Air Quality Mainten-
ance Area.  The allocation and projection methodology is essentially that
of Volumes 7 and 13 of the Guidelines for Air Quality Maintenance Plan-
ning and Analysis series published by the United States Environmental Pro-
tection Agency.

     The published report contains county and AQMA level estimates of res-
idential and non-automotive transportation emissions for the base and pro-
jection years.  It also includes the expected growth or decline of the com-
mercial and industrial emissions.  Actual commercial and industrial emis-
sions are not contained in this report due to possible changes in the New
York State Department of Environmental Conservation base year emission
estimates.  UTM cell level data is stored in the files of the New York
State Department of Environmental Conservation.

     Due to the limited growth projected for the Capital District and the
trend towards electric space heating, only the commercial area source
emissions are expected to show significant growth over the next 25 years.

     This report was submitted in fulfillment of Contract No. 68-02-2314
by the Capital District Regional Planning Commission under the sponsor-
ship of the U. S. Environmental Protection Agency.  This report covers
the period May 1, 1976 to May 31, 1977, and work was completed as of
May 31, 1977.

                EMISSION INVENTORY BY UTM GRID CELL
      CAPITAL DISTRICT (NEW YORK) AIR QUALITY MAINTENANCE AREA
                            INTRODUCTION

     The New York State Department of Environmental Conservation is required
to perform an analysis of the Capital District Air Quality Maintenance Area
to insure that the ambient air quality will be maintained at a level that
does not violate Federal Standards.  Part of this analysis includes diffusion
modeling of the Region's air quality with proposed pollution sources in oper-
ation.  In order to properly perform this diffusion modeling, an inventory of
air pollution emissions by UTM Grid Cell is required for the current year and
for any future years to be analyzed.

     The Capital District Regional Planning Commission has generated popula-
tion land use and transportation data at the UTM Grid Cell level as part of
its ongoing comprehensive planning efforts.  The purpose of this contract is
to transform CDRPC's data into the emission data required for input to the
diffusion model.  This is being done for two pollutants:  Particulate Matter
and Sulfur Dioxide.
                        GENERAL INFORMATION

CELL IDENTIFICATION - CDRPC does its computer planning work on the basis of
UTM Grid cells.  However, CDRPC's numbering system is such that a point to
the south west of the Region is (0,0) and all numbers are less than 999, al-
lowing a six digit coordinate identification.  The first three digit number
is the east-west number and the second is north-south.  It is a simple mat-
ter to convert from CDRPC to UTM, however, as all of CDRPC's raw data is
stored by CDRPC ID, all products generated in this contract give the CDRPC
coordinate.  When the data is combined for modeling, the following adjust-
ments should be made:

     555 should be added to the first three digits to get UTM Easting;
     4692 should be added to the second three digits to get UTM Northing.

-------
DATA AVAILABILITY - All computer programs and data files generated under
this contract have been delivered to NYSDEC in paper copy form.  Addition-
ally, machine readable versions have been delivered to NYSDEC through the
use of a special CDRPC mass storage file named AIR.  AIR. was established
by CDRPC and any data to be transferred is read into the AIR. file by CDRPC
and used by NYSDEC.  Due to the large amount of data generated under this
project, DEC has asked CDRPC to store most data on computer tape to be re-
trieved, if necessary, at a future date.  CDRPC has complied with this re-
quest.

     A list of all programs and data files with a summary of their contents
is contained at the end of this GENERAL INFORMATION Section.  This informa-
tion should allow interested persons to request copies of data elements or
programs for inspection as required under 40FR51, section 51.62.

     A complete dump of all AIR. files is a 6" thick stack of over 2000
pages costing over $80.00 to print.  Therefore, due to the limited useful-
ness of such a dump, only one copy of most data exists.   These copies have
all been delivered to NYSDEC, and CDRPC does not intend to print such a
dump again.  If copies of specific programs or data files are necessary for
the review of this work, they will be printed on request.

POPULATION AND ECONOMIC PROJECTIONS - When this project was initiated, CDRPC
stated its intent to base all projections on CDRPC's Preliminary Regional
Development Plan.  The projections in the plan were consistent with Office
of Planning Services Regional projections.

     Since that time, the NYS Economic Development Board (EDB) has come up
with new population projections (and by implication new economic projections)
that result in a 1.3% higher SMSA level population in the year 2000, but a
10% lower AQMA population.  A more detailed comparison of the figures is
contained at the end of this subsection.  CDRPC has not revised its Regional
Development Plan to correspond to EDB's projections.  However, CDRPC is con-
sulting with its member counties during the plan refinement stage to arrive
at mutually acceptable population projections for the small areas in the
Region.

     It is evident that the revised projections will be somewhere between
CDRPC's Plan populations and EDB's projected populations.  However, no hard
numbers are available at this time.  Therefore, CDRPC did all AQMA projec-
tion work with its Plan socioeconomic projections.  It can be expected that
any revised population projections will result in a more dispersed develop-
ment pattern, and thus lower area source contributions to the hot spots.

     Based on past experience, New York State can be expected to revise its
projections for the Capital District almost every year.  (Since 1974 the
State has changed the Region's year 2000 population from 910,000 to 885,000
to 897,000).   It is not practical or useful to redetail all of CDRPC's work
every year based on these marginal changes in the total population.  There-
fore, the projections used in this report will be the most up to date ones
available from CDRPC until after the Regional Development Plan consultation

-------
process is complete, and the Plan is adopted.

                         RESIDENTIAL EMISSIONS
As of this date (November 30, 1976) NYSDEC has not been able to provide
CDRPC with county level area source inventories.   Therefore, CDRPC has
computed residential emissions entirely from its own data sources and a
modification of the order 3 methodology from Guidelines for Air Quality
Maintenance Planning and Analysis Volume 13:  Allocating Projected Emis-
sions to Sub-County Areas.  The input data consisted of:  the actual 1970,
and projected 1980, 1990 and 2000 populations by Traffic Analysis Zone; a
Traffic Analysis Zone to UTM grid conversion table; the Bureau of the Cen-
sus publication PHC (1)-A Census Tracts, Albany-Schenectady-Troy, N.Y.;
the Bureau of the Census Public Use Sample for the Albany-Schenectady-
Troy, N.Y. SMSA; unpublished State of New York Economic Development Board
population and household projections and internal CDRPC data.  Each of
these data sources is discussed in detail where appropriate.

     POPULATION BY UTM CELL - The first step in the residential emission
procedure was to obtain population by UTM cell for the years required for
AQMA work.  This was done using two CDRPC data files and a computer pro-
gram.  Data file AIR2 is an AQMA only copy of CDRPC's file BLDBLK listing
the CDRPC coordinate, TAZ number, sub-region, and Minor Civil Division as
well as certain macro level estimates of existing and future development
for each cell.  Data file AIR3 is a copy of TAZPOP, developed as TOMPOP
and described in the attached 1975 technical memo #501 Small Area Fore-
cast lists the TAZ number and TAZ level population for the years 1970,
1980, 1990 and 2000.  A CDRPC program AIR4 splits the TAZ level popula-
tions to the cell level using the fact that TAZ's were designed to be
homogeneous.  Thus, if there are 10 cells in a TAZ, the population of each
cell is simply the TAZ level population divided by 10.  The output of this
process is AIR6, a data file containing cell coordinate, TAZ number, and
cell population for 1970, 1980, 1990 and 2000 for each of the 2152 cells
in the AQMA.

     There are a few cells that contain more than one TAZ, yet AIR4 can
match only one TAZ to a cell.  The program therefore makes a list of TAZ's
not matched to cells and a hand edit of the data to include the populations
of these TAZ's is required.  This edit is done directly on the data in AIR6
and the current version of AIR6 includes all necessary hand changes.  A
list of the TAZ's included in the hand changes is in the appendix of this
document.

FUEL SPLIT - The Census of Housing contains data on household heating fuel
use by county and certain cities.  It would be inappropriate to apply heat-
ing fuel splits from the city or county level to all cells in the city or
county.  Therefore, CDRPC developed a method of estimating heating fuel use
by census tract.  Program AIR7 creates a data file (named AIRS) of 2517
households and their heating fuel use, number of units/unit, heating equip-
ment and year built from the Public Use Sample Tape.   The public use sample
is a 1% selection of actual 1970 census returns with all name and address
information removed.  The reason for creating this file is that number of
units/unit, heating equipment type and year built are all reported at the
census tract level, while heating fuel use is not.

     The program AIR9 is an SPSS cross-tabulation of heating fuel type
against each of the other three data types.

     The resulting tables were modified to account for areas where pipeline
gas is not available, and the only available gas is the more expensive LP
gas commonly called propane.  The areas with no gas available were deter-
mined through discussions with Niagara Mohawk service representative (and
CDRPC Commissioner) Thomas McGrath.  The resulting tables are:

           The following AQMA towns have no pipeline gas available:

Albany County - Towns of Coeymans, New Scotland and Census Tract 146.05 in
    the Town of Guilderland
Rensselaer County - Towns of Poestenkill, Sand Lake, 75% of Schaghticoke,
    and 65% of Brunswick
Schenectady County - Town of Princetown, Census Tract 326.0 in the Town of
    Rotterdam and Census Tract 325.01 in the Town of Glenville.

     Thus, we can determine that while 46.2% of the Region's households heat
with piped gas, only 1.8% of the mobile homes are heated with piped gas.
From the output of AIR9, equations giving the number of dwelling units using
a given heating fuel type can be developed for each of the three data items
reported in the census tract book.  Each of these three equations has some
flaw that makes it undesireable to use it alone for generating tract level
heating fuel uses.  For example, each equation has one data choice that con-
                                     14

-------
tains over 50% of the total sample.  (These categories are single-family
detached, 54.1%; built before 1939, 56.4%; and steam or hot water heating
equipment, 50.3%).

     It was felt by the CDRPC staff that while no single equation was
clearly superior to the other two, all had some strengths, and the heating
fuel types for a tract could reasonably be estimated by taking the average
of the estimates given by each of the three equations.  The mechanics in-
volved were to build data file AIR10 containing tract number, total house-
holds, units in structure, year built and heating equipment from the tract
book.  Then the program A1R18 was written to predict households by fuel
type for each tract by each method and to take the average of the three
equations.  The total output of AIR18 was printed so that it could be man-
ually skimmed for any gross inconsistencies between formulas and the aver-
ages were written as data element AIR11.  This process gave households by
fuel type by census tract.  For AQMA work this information is required at
the UTM cell level.

     No TAZ boundary crosses a census tract boundary.  Therefore, each cen-
sus tract can be viewed as consisting of many TAZ's.  Element AIR13 is list
of each TAZ with the number of the tract it is in.  Program AIR12 attaches
this information to the adjusted cell level populations from AIR6 and the
aggregate information is stored in AIR14.  As with AIR6, problems of lost
tracts occurred in densely developed areas where more than one tract was
located in a single UTM cell.  These problems were addressed by manually
editing AIR11 to combine tract data so that each combined tract represented
a minimum of one entire UTM cell.  Program AIR15 was used to check element
AIR14 by adding up the TAZ population data to the tract level for compari-
son with the census tract book.  Program AIR16 checks element AIR11 by com-
puting total households by heating fuel type for the AQMA for comparison
with SMSA level data.  The AQMA is smaller than the SMSA so the totals from
AIR16 should be less than the numbers in the tract book.  The output of
AIR11 accounts for 92% of the gas, 91% of the electric, 89% of the oil, 98%
of the coal and 61% of the wood heating fuel in the SMSA.

     Program AIR22 takes the information from the adjusted AIR11 and AIR14
and gives each cell a share of the tract households by fuel type propor-
tional to the ratio of the cells population to the total tract population.
This method assumes a constant fuel split in a tract, and as no better in-
formation is available the assumption is necessary.  The output of this
program is AIR23 which gives the number of dwelling units using each fuel
type for each UTM cell for 1970.

     The results of this process AIR23 contains data on over 2000 cells.
This information is so detailed, it is hard to check it for reasonableness.
Therefore, a program (AIR23ADD) was written to sum this information to the
county level.   The results are presented below:

RELATIVE FUEL REQUIREMENTS -  Volume 13 of the Guidelines goes into great
detail over the fact that multiple unit buildings use less fuel per unit
than do detached single family dwellings.  This effect is very important
to the Capital District AQMA as most dwelling units near the "hot spots"
are primarily multiple family units.  The units in structure data from the
census tract book was used to arrive at RFR's for gas and oil for each
tract.  The only problem in this process is that volume 13 breaks down the
census tract book's 5 to 49 class into three classes (i.e. 5 to 9, 10 to
19, 20 to 49).  Data from the public use sample tape was used to determine
a composite RFR for the 5 to 49 unit group for each fuel type.  The results
are coal .47, oil .721, gas .672.  Program AIR30 uses information in data
file AIR11 and volume 13 of the Guidelines to compute an RFR for each tract
for 1970.

OTHER YEARS - The Process described above gives the data necessary to cal-
culate residential fuel use by UTM cell for 1970.  However, the maintenance
analysis contract requires this information for the years 1975, 1980, 1985,
and 1995.  As there is no published measured data for 1975 which is compar-
able to the 1970 Census of Housing, and since the years 1980, 1985 and 1995
are in the future, a method of projecting changes since 1970 was developed.

     The first step is to subtract the population due to group quarters
from the cell level population contained in AIR14 for 1970, 1980, 1990 and
2000.   It would have been desireable to do this for the 1970 work, however,
as the actual count of households per tract (instead of a number computed
from household size and population) was used for that work, the inclusion
of group quarters population in a tract made no difference.

     The next step was to obtain estimates of average household sizes for
the future.   The New York State Economic Development Board has published
projections of both population and numbers of households by county.  Thus
for a given county the average household size in a future year is the pro-
jected population divided by the projected number of households.  The re-
sults of this process are:

     The third step was to determine the number of inhabitants projected
to live in a cell that would not be housed in the number of housing units
currently in the cell.  For example:

     A cell in Albany County has 305 people in 1970, this is 100 housing
     units.  With declining household size, these same 100 housing units
     would be expected to house 274 people in 1980, so 31 people would
     need new housing units by 1980 if there was no change in the cells
     population.  Any changes to the cells total population between 1970
     and 1980 would be added to or subtracted from this 31 people to get
     the total number of people in the cell requiring new housing.

     This work was done by a computer program called L (because of a key-
punch error) and the results — a list of the number of people needing  new
housing in 1980, 1990 and 2000 by cell is data file AIR26A.  This informa-
tion plus average household size allows us to project new dwelling units
per cell; but for emissions, a fuel split is necessary.

     FUTURE YEAR FUEL SPLITS - Given present technology, the number of  new
homes with coal or wood heat is significant.  Additionally, no new natural
gas hook-ups are presently allowed, and there is no evidence to suggest that
this ban will end.  Therefore, almost all new dwellings can be assumed  to  be
heated with oil or electricity.

     The tables of heating fuel type versus year built obtained from the
cross tabulations of AIR9 show that the percentage of new residential dwel-
lings using electric heat has increased dramatically from less than 1%  of
units built before 1960 to 22% of units built in 1969 and 1970.  If this
trend continues, all new housing units will use electric heat before the
year 2000.

     The only available projections of electric vs non-electric (assumed  to
be oil) heating are those used by the electric utilities in the load fore-
casting section of their annual 149-b long-range plans submitted  to the New
York State Public Service Commission.  Their contention is that the easily
useable fuels (i.e. oil and gas) are becoming scarce and expensive, and that
electric utilities are much more able to use dirty fuels such as  coal,  dang-

 erous fuels such as nuclear and hard to tap sources of energy such as hydro
 and geothermal.  This ability and the scarcity of clean fuels will overcome
 the thermodynamic inefficiencies of present electric generation technology
 and give electric heat a very large share of the new housing market, and a
 reasonable share of the heating plant replacement market.  It should be
 noted that the 149-b Plans are internally consistent, and that sufficient
 new generating capacity is contained in the Plans to meet the projected
 loads from all new sources including new electric heating customers.  Figure
 1 of this report, which is Exhibit 2 of the 1976 149-b Plan, shows the loca-
 tion of major generating additions planned through 1990.  None are in the
 Capital District AQMA.

      To estimate the future electric vs non-electric fuel splits, the load
 forecast projections of the two electric utilities serving the Capital Dis-
 trict AQMA were examined in detail.  These two utilities are:  the Niagara
 Mohawk Power Corporation which serves most of the AQMA, and the New York
 State Electric and Gas Corporation.

 Service Area is contained in Table 15 "APPLIANCE CONTRIBUTION TO KWH GROWTH"

     It can be seen that, if the actual numbers are correct, Niagara Mohawk
 is consistently underestimating actual new electric heat as a % of new units,
 while NYSE&G  is consistently overestimating such heating.  The average of the
 two numbers is, however, very close to the actual.

     CDRPC's  original estimate of these percentages used in the AQMA analysis
 is essentially the average of the NYSE&G and the N-M estimates except for
 1990 which is not a year for which data is required under this contract.  For
 the year 2000, CDRPC held to its 1990 and 1995 estimate of 80%.  This can be
 expected to be below the average of the NYSE&G and N-M year 2000 estimates if
 they follow the same trends as in the past.  The table below verifies the
 closeness of  these CDRPC estimates to the average of the NYSE&G and N-M esti-
 mates .

New Dwelling Units/Cell - The program AIR27 takes the additional population
to be housed in a cell for a future year,  divides it by the average house-
hold size for that county for the year and gets new housing units per cell
for that year.  It then multiplies these cells by the fractions electric
and non-electric to get new dwelling per cell by fuel type for 1980, 1990
and 2000.   This data is in file AIR28.

Future  RFR's - The CDRPC preliminary Regional Development Plan gives the
expected additional acres of residential development for each Minor Civil
Division through the year 2000.   Program AIR29 finds the total additional
dwelling units per Minor Civil  Division through the year 2000.  The RFR for

    Thus each city and town has a single RFR for future development.
These numbers were calculated manually from the output of AIR29.

Years 1975, 1985, 1995 - CDRPC has not made detailed projections  to the
five year level.  Whenever information is needed for these mid-decade
years, it is found by interpolation from the projection years surrounding
it.  In this case, it was assumed that at the cell level the number of new
dwelling units for a mid-decade year could be considered the linear average
of the two end points of its decade.  Thus new growth to 1975 is  50% of new
growth to 1980.  This assumption seems superior to making many assumptions
concerning varying rates of population growth, household formation, etc.
 Program AIR32 uses this assumption along with the fuel type assumptions
listed earlier to yield new oil and electrically heated homes by  cell for
1975, 1980, 1985, 1990 and 1995.  This data is stored as AIR33.

    As with AIR23, the data in AIR33 is not easily understood at  the cell
level.  Therefore, the following table of AIR33 summed to the county level
was generated by a program called AIR33ADD.

FUEL USE - Residential fuel use can be generated for each cell using fuel
use factors from Volume 13 of the Guidelines and in the case of wood APTD-
1135.   For a single family dwelling, these factors are:

                              Coal    2.38 Ib./DD
                              Oil     .157 gal/DD
                              Gas     26.6 ft. /DD
                              Wood    3.4 Ib./DD
                              DD   =  Degree Days

                                      21

-------
    For the Capital District AQMA, DD = 7,462, so for single-family dwell-
ings, the average annual fuel requirements are:

                            Coal   8.88 Tons/year
                            Oil    1.17 x 10 ftGal/year
                            Gas    0.199 x 10  Ft /year
                            Wood   12.7 Tons/Year
                                                              3
    Thus the fuel use for a cell for 1970 for oil = (1.08 x 10  gal) *
(number of oil heat dwellings from AIR23) * (RFR for tract from AIR31).
And, additional oil fuel use in future years is:  (1.08 x 10  gal) * (num-
ber of additional oil heat dwellings from AIR33) * (RFR for MCD from out-
put of AIR29).  In this manner the fuel use per grid cell by type of fuel
for each target year can be estimated.  These calculations are done by
program AIR33P which has been run for the contract years 1975, 1980, 1985,
and 1995.  The outputs are stored as AIR75FUEL, AIR80FUEL, AIR85FUEL, and
AIR95FUEL.  Each of these data elements contains the census tract, CDRPC
coordinate, TAZ, MCD, MCF of gas, 1000 gallons of oil, tons of coal, and
tons of wood consumed for each of the 2152 cells in the AQMA for the indi-
cated year.

    These fuel elements are difficult to understand at the cell level.
Therefore, a program called FUELADD was written.  This program sums the
fuel elements by county, and calculates the emissions using AD-42 emission
factors.

-------
            COMMERCIAL - INDUSTRIAL - INSTITUTIONAL ALLOCATIONS
    There is no reliable way to generate fuel use estimates for these
classes from the bottom-up using published information as there is for
the residential class.  Therefore, SMSA level area emissions are to be
allocated to grid squares using the appropriate type of employment.
Obviously, the employment must be adjusted for any point sources so that
cells containing point sources are not also allocated area emissions for
the employment covered by the point source.

    EMPLOYMENT DATA - CDRPC has employment data by category by TAZ as
described in the attached 1975 Memo #501 Small Area Forecast.   The first
step was to organize the data in the existing file for AQMA use.  A re-
cent NYS DEC decision is to compute all non-residential area sources as
industrial or commercial - institutional - government (hereafter called
commercial for convenience).  Industrial employment corresponds to CDRPC
employment Group 3 or manufacturing (SIC's 19-39), while commercial em-
ployment corresponds to CDRPC groups 4, 5, 6, 7, 8 and 9 (SIC's 40-50,
52-67, 70-86, 89-93 and 99) it should also include a part of CDRPC group
1; however, due to the small size of this group, its exclusion should not
affect the allocations.

    LAND USE COUNT - Although TAZ's are chosen to be homogeneous; due to
the very limited geographical extent of these uses, (Commercial 0.7%,
Industrial 0.6%, and institutional 1.1% of regional land) it would be
inaccurate to allocate a TAZ's employment evenly among the cells in the
TAZ.  Therefore, a manual count of industrial, commercial and institu-
tional land use per cell for the AQMA from a 1" to 1 mile land use map
was undertaken.  The land was counted in hectares so the count for a cell
was also the percent of the cell with that land use type.  The results of
this count are coded in AIR37 which gives the TAZ, cell ID, and percent
commercial, institutional and industrial for each of the 2152 cells in the
AQMA.

    EMPLOYMENT PER CELL - Computer program AIR42 allocated existing em-
ployment by TAZ to cells based upon the land use counts in hectares for
cells within the TAZ.  Land use measurements are not perfect (many parcels
of land are mixed use, but coded only as one use); therefore, in some TAZs
there were no cells with land uses corresponding to the type of employment
in the TAZ.  In this case, the program allocated the employment evenly be-
tween the cells in the TAZ.  The output of this process is AIR45, a list
of employment by appropriate group for each of the 2152 cells in the AQMA.
                                       25

-------
    POINT SOURCE ADJUSTMENT -  Data file AIR45 gives total employment by
group by cell.  As mentioned in the introduction to this section, employ-
ment associated with point sources  must be subtracted out before this in-
formation is useful for area emission allocation.  The employment associ-
ated with the greater than 10-ton year combustion point sources in the
following table was manually subtracted out of file AIR45 and the result
stored as AIR45AREA.

    ALLOCATING BASE YEAR EMISSIONS - Once the employment associated with
all point sources  is  subtracted  out, the SMSA contains a total of 29,053
area source  industrial  employees.  Thus the share of industrial area emis-
sions for a  cell in the AQMA = cell ind emp/SMSA ind emp.  Similarly, for
commercial,  there  are 150,865 area commercial employees in the SMSA and
thus the share of  area  commercial emissions for a cell in the AQMA = cell
com emp/SMSA com emp.   In order  to facilitate the necessary calculations,
the data file AIR46EMP  was generated from AIR45AREA.  AIR46EMP is simply a
list of the  total  industrial and commercial area employment per cell for
1974.  The problems associated with multiple TAZ cells in the residential
work also existed  in  this commercial industrial work, and AIR46EMP was manu-
ally edited  to include  these other employees.

    PROJECTION OF  FUTURE EMISSIONS - Future year emissions were calculated
from base year emissions and growth (or decline) factors.  In lieu of soph-
isticated technological analysis, the assumption was made that emissions
per employee remains constant over time.  The result of this assumption is
that for each point and area source, future emissions can be estimated from
base year emissions if  future employment is known.  In order to make maximum
use of existing data, the apportionment of future emissions was done in
three steps.

    INDUSTRIAL POINT SOURCE:  The SIC number is known for each point source.
CDRPC's Technical  Report 500-4 Population, Income and Employment Forecasts
for the Capital District Region gives regionwide employment by sector for
future years (Table 16  on page 41).  These sectors were converted to SIC
groups and the growth or decline rate for each SIC group to future years
was computed.  Next, it was assumed that each individual point source in-

-------
dustry had the same growth or decline rate as that industry has on a
regional basis.  The result is a series of growth factors listed below.
Note that as 1995 employment was not listed on Table 16, it is found by
linear interpolation from projections of 1990 and 2000 employment.

    Applying the factors shown above to the base year employment  for  each
company results in a projection of the total AQMA point source employment
growing from 28,062 in 1975 to 28,997 in the year 2000.  This is  counter to
the trend for all industries and indicates that these industries  will con-
tribute a greater air pollution load than would be suspected from an  exam-
ination of total industrial employment.  In order to estimate area source
employment, it is also necessary to consider industrial point sources in-
side of the SMSA but outside of the AQMA.  An identical process was fol-
lowed and the following summarizes the results.

    INDUSTRIAL AREA SOURCES:  CDRPC data file EMPLOYMENT70 was subtracted
from file EMPZONE200-R to give the projected change in employment by TAZ
for each employment group between 1970 and 2000.  This data was compressed
into the commercial-industrial breakdown and limited to AQMA TAZs.  Addi-
tionally, the corrections necessary to adjust for multiple TAZ cells were
made.  Next, the changes in point source employment developed above were
added to or subtracted from the appropriate TAZs.  The output of this
largely manual process is a data element AIR44AQMA which contains the pro-
jected changes in area source industrial and commercial employment for
each TAZ in the AQMA through the year 2000.  Total industrial employment
is given in Table 15 of CDRPC report 500-4 referenced above.  Total point
source employment is given above, thus the total area source industrial
employment for each contract year can be computed.

    If each cell in a TAZ is assumed to change the same percentage and
direction as each other cell in the TAZ (a reasonable assumption due to
the homogenity of a TAZ), then the cell level employment in a future
year can be computed as follows:

    COMMERCIAL POINT SOURCE EMPLOYMENT:   The commercial class of employ-
ment is projected to grow by almost 100% by the year 2000.  Yet, individ-
ual point sources (schools, hospitals, shopping centers, etc.) should
experience no additional heating loads, and the trend is towards most
commercial employment locating in area type of sources.   Therefore, it
was decided to project all commercial point sources at the same level
throughout the contract period.  That is, no growth or decline in employ-
ment or emissions.

    The above decision was made after examining trends in commercial con-
struction.  From the list of point sources, it can be seen that the most
recently constructed commercial point source (over 25 tons/year) is Colonie
Center (Homart Development Company) constructed in 1965.  Such recent com-
mercial ventures as Northway Mall and Mohawk Mall, office buildings such
as the new Federal Building, the 855 Central Avenue complex, Executive
Park and 50 Wolf Road, and even hospitals such as Leonard are all area
sources due to the use of gas, distillate oil, or electric heat, or due to
their size.  These facilities are as big as anything expected to be built
in the Region over the projection period.  Therefore, the above assumption
that there will be no new commercial point sources appears valid.

    COMMERCIAL AREA SOURCE EMPLOYMENT:  Data file AIR44AQMA also includes
the total change in commercial employment for each TAZ from the base year
to 2000.  The assumption that commercial point source employment is con-
stant throughout the contract period means that no adjustments in AIR44-
AQMA are necessary to account for any changes in point source employment.
Therefore, the generation of future year cell level area source commercial
employment estimates is:

Future year  =  (Base year)    (Cell Emp    ) A                 future     }
Cell Emp        (Cell Emp )    (Chg. to 2000)             &            3   '

    The % 2000 change to future year is computed as follows using informa-
tion from Tables 16 and 17 of CDRPC's Report 500-4.

    COMPARISON OF AQMA TO SMSA - Programs TEST, TEST44 and TEST46 are
used to obtain AQMA level summations of the data in files AIR51,  AIR44-
AQMA and AIR46EMP respectively.  The outputs of these programs can be
used to make comparisons between the AQMA and the SMSA.  While these
comparisons are not needed for any maintenance analysis, they are in-
teresting and do serve to illustrate the reasonableness of the outputs
of the sequence of programs described above.  The following table con-
tains these comparisons.

    FUTURE YEAR AREA SOURCE EMISSIONS -  CDRPC was originally to use the
figures derived above to allocate given area source totals to the cell
level.  However, NYSDEC has been unable to provide the necessary indust-
rial and commercial area source totals.  Therefore, NYSDEC will have to
use the data in AIR46EMP and AIR51 to allocate area source emissions.
The specific procedure is to take the 1975 SMSA level commercial area
source emissions and divide it by the 1975 SMSA level commercial area
source employment  (150,865).  The resulting number is the area source
commercial emissions per employee.  This number is simply multiplied by
the number of commercial employees in each cell for the year desired.
This last number is obtained from AIR46EMP for 1975 and from AIR51 for
1980, 1985, 1995 and 2000.

    Industrial area source emissions are similarly found by dividing the
SMSA level 1975 emissions by 29,053 and using  the resulting emissions
per industrial area source employee with the appropriate count of area
source industrial  employees per cell.

    In view of the lack of SMSA level area  source commercial and indust-
rial emission estimates for the base year,  CDRPC feels  that data files
AIR46EMP and AIR51 complete the requirements of the contract with respect
to commercial and  industrial space heating  emissions.

                          TRANSPORTATION EMISSIONS
    Auto and truck traffic on public roadways accounts for the vast major-
ity of transportation related emissions.  However, small amounts of emis-
sions are concentrated at certain airports, railroad yards and the Port of
Albany.

    PUBLIC ROADWAYS -  CDRPC obtained the NYS Department of Transportation's
air pollution emission runs for 1975, 1985 and 2000 from the Capital Dis-
trict Transportation Committee.  These runs give the emissions for each
Traffic Analysis Zone for particulates but not SO .   A major problem with
the data is that the TAZs used for these runs are different from those cur-
rently used for planning purposes by CDRPC and CDTC.  Therefore, it was
necessary to obtain a map of these zones and determine what DOT TAZ each
AQMA cell was in.  This information is stored as AIR55 which contains DOT
TAZ, CDRPC TAZ, cell ID, census tract and MCD for each cell in the AQMA.
Data element AIR56 contains the DOT emission data for 1975 and 1985 for
each DOT TAZ.

    Program AIR57 allocates the particulate emissions to UTM cell, assum-
ing that within a TAZ the emissions are evenly distributed.  The program
also estimates S0« emissions as .3833 of particulate emissions based on
Table 3.1.1-1 of  AP-42.  Interpolation of this data to 1980 and 1995 was
done by straight line projections of the emissions from NYS DOT.  The out-
put of this process is a data element called AIRAUTOCD.

    AIRPORTS - CDRPC report 200-3 Schenectady County Airport Environs Study
contains estimates for aircraft emissions from the Schenectady County Air-
port (CDRPC cells 032051 and 032052) for 1970 and 1990.  The limited growth
projected for the Schenectady Airport indicates that a straight line pro-
jection through these years is reasonable.  Therefore, the following emis-
sions should be loaded into the airport's cells.

         SCHENECTADY COUNTY AIRPORT AIRCRAFT EMISSIONS (TONS/YEAR)

    For the Albany County Airport (CDRPC cells 042040, 042041 and 043040)
emissions estimates were prepared using projected operations and fleet mix
data prepared as part of the Albany County Masterplan work now underway by
Parsons Brinkerhoff Quade and Douglas (PBQ&D), and emission factors from
                                       33

-------
AP-42.  xt should ba noted that as the masterplan study is still underway
some estimates of the future facilities to be available at the airport had
to be made, and that the emissions estimates to be prepared as a part of
the masterplan study might be different than those estimated by CDRPC.  It
is expected that in any differences due to facility constraints, CDRPC's
estimates would be higher than PBQ&D's.

             ALBANY COUNTY AIRPORT AIRCRAFT EMISSIONS (TONS/YEAR)
                   1975      1980      1985      1995
Particulates      21.28     23.53     25.99     38.70
S02               22.96     25.43     28.77     46.25


    There are six other general aviation airports in the AQMA.  They are
characterized by short (less than 3,000 feet) often unpaved runways and
cater to single engine piston aircraft.  If it is assumed that each of
these airports has 1000 LTO's or 2000 operations a year, the air pollution
emissions based on AP-42 would be 20 Ibs. of particulates and 14 Ibs. of
SO-.  Therefore, emissions from these airports were not included in the
allocation.

    RAILROAD YARDS - CDRPC is unable to obtain the railroad fuel use data
necessary to estimate railroad emissions.  However, NYS DEC has estimated
railroad emissions for Albany, Rensselaer and Schenectady Counties.  CDRPC
has chosen to allocate these emissions as follows:

ALBANY COUNTY - to the switching yard at Selkirk, CDRPC cells 040018 and
041017.  TOTAL EMISSIONS 23.6 Tons Particulates, 53.8 Tons SO .

RENSSELAER COUNTY - to the Amtrack facilities in Rensselaer, CDRPC cell
048029.  Total Particulates 2.5 Tons, Total SO,-,, 5.7 Tons.

SCHENECTADY COUNTY - to the Rotterdam Depot, CDRPC cell 027044.  Total
Particulates 1.2 Tons, Total SO , 2.8 Tons.

    Due to changing Federal and State policy towards railroads, it is
difficult to project future railroad emissions.  Therefore, CDRPC feels
that NYS DEC's base year estimates should be used for future contract
years until other data becomes available.

    PORT OF ALBANY - The Port of Albany is a deep water Port with a channel
depth of thirty feet.  In 1974, there were 120 reported vessel calls.  Us-
ing the assumptions on Page 5-23 of USEPA Document APTD-1135 Guide for
Compiling a Comprehensive Emission Inventory of a three-day stay and 660
gallons of residual oil per day, the annual fuel consumption is 3 days X
660 gal/day X 120 ships = 237,600 gallons.

    Using the emission factor from Table 3.2, 3-1 of AP-42 for S02 of 27
lb/1000 gal, annual emissions are 6,415.2 Ibs. or 3.2 tons.
                                       34

-------
    For particulates, the emission factor is 1.04 Ib/hour so 120 ships
X 3 days/ship X 24 hours/day X 1.04 Ib/hour = 8,986 Ibs. or 4.5 tons/
year.

    The Port is located in CDRPC cells 047027, 046026 and 046025.   There-
fore,  the vessel emissions in the Port for each of these cells is  1/3 of
the total, or 1.5 tons particulates, 1.1 tons S0?.

-------
                             INDUSTRIAL EMISSIONS
    Industrial heating emissions are discussed in the section entitled
Commercial-Industrial-Institutional Allocations.  Base year industrial
process emissions are all contained in DEC's AIR100 Emission Inventory
File.  For future years, these process emissions should be adjusted by
the following growth factors based on 2-digit SIC groups.  (Source

                          INCINERATION EMISSIONS

    Incineration emissions are also contained in DEC's AIR100 Emission
Inventory File.  There is no reason to expect significant changes in
incineration emissions over the projection period.  Therefore, the data
in DEC's AIR100 File should be used for the base and projection years.
                           POWERPLANT EMISSIONS

    The only non-hydro powerplant in the AQMA is Niagara Mohawk's Glen-
mont facility.  Its emissions are included in DEC's Point Source File,
and the Facility is expected to remain in operation at its current
level throughout the projection period.  Therefore, DEC's data should be
used for the base and projection years.

PURPOSE:  The purpose of this project is to create  1970,  1980,  1990

and 2000 population and 1970 and  2000 employment  (by SIC  group) data

bases by small areas that are consistent with the large area pro-

jections in CDRPC's preliminary Regional Development Plan, a Consul-

tation Document.  These data files are to be stored in CDRPC's

computer facilities for use in future projects.

SMALL AREA:  The first task was the choice of an appropriate "small

area".  Ideally, this would be a  neighborhood no larger than a  1 km

by 1 km UTM grid cell.  Data at this level could be aggregated  to

any desired level for use.  However, neighborhoods  usually do not

have well defined boundaries.  Additionally, the smallest level

for which substantial base year  (1970 or 1973) data is available is

the Traffic Analysis Zone  (TAZ).  TAZ's have the desirable traits

of being smaller than any other common statistical  unit  (e.g. minor

civil division or census tract),  having boundaries  that do not

cross the boundaries of other common statistical units, having  a

degree of homogony in a given TAZ (i.e. approximating  artificial

neighborhoods) and of being smaller than a 1 km by  1 km UTM grid

cell in urban areas.  In view of  these traits, the  availability of

population, land use and some employment data by TAZ for  the base

year and the fact that the limited scope of this project  precluded

generation of substantial amounts of new data, the  TAZ was chosen

as the small area.
                                       39

-------
POPULATION:  The 1970 population for each TAZ was obtained by adding



up the census populations of each block within the TAZ.  This work



was part of that completed as the background for the RDP, and was



not part of this project.  The changes between 1970  and the year



2000 for each Minor Civil Division  (MCD) were calculated from RDP



projections.  The apportionment of  the MCD  level changes to TAZ's



was conducted as follows:



     The Regional Building Block year 2000  Preliminary Regional



Development Plan (the preparation of which  is described in CDRPC



Technical Report 100-1  Methodology for the Preparation of Regional



Development Plan Alternatives)  was utilized to find the portion



of the expected change  for an MCD that a particular TAZ was expected



to receive.  The Taz was then allocated this portion of the MCD's



1970 to 2000 population change.  This quantity was identified as



"CHGPOP"  (change in population).  The use of this proportioning




method and CHGPOP rather than the absolute  population changes



predicted for each TAZ was necessary because the limited number of



quantized change possibilities presently allowed by the building



blocks resulted in the plan both over and underestimating the year



2000 populations of the different MCD's.  However, although the



absolute numbers of population change indicated by the building



blocks are not correct, the relative proportion of change and type



of change for each TAZ are correct.  Thus the use of the propor-



tion of change for each TAZ by MCD  gives  a close estimate of the




expected year 2000 population by TAZ.
                                      40

-------
     To find the 1980 and 1990 populations of each TAZ, the rates

of population change for each decade for each of the  five sub-

regions described in the RDP was determined.  The appropriate rate

was then applied to the CHGPOP for each TAZ for each  decade and

the 1980 and 1990 populations obtained.  This was completed using

the computer program POPJOY attached in the appendix.  As indicated

in POPJOY, a slight modification of this approach was utilized

for the Central Cities Subregion.  This is because the Central

Cities as a group are expected to lose population between 1970

and 1980, then they are expected to gain population after 1980.

However, some TAZ's which are presently overcrowded or in the way

of redevelopment, are expected to lose population between 1970 and

2000.  Applying the negative growth rate for the Central Cities

group to these TAZ's would result in them gaining population be-

tween 1970 and 1980.  This is not likely  to happen,  so the 1980

population for each TAZ in the Central Cities Subregion was deter-

mined by multiplying the ratio of the Central Cities  1980 popula-

tion to its 1970 population by each TAZ's 1970 population.  The

Central Cities 1990 TAZ populations were estimated in the same

way as those of the other groups.

     The output of this process is a computer element named TOMPOP

containing the census tract, TAZ number, 1970, 1980,  1990 and 2000

populations and subregional group number for each TAZ.  A copy of

the information in this file is in the appendix of this document.

EMPLOYMENT:  At the beginning of this project, CDRPC  had no employ-

ment information by TAZ.  Initial attempts to create  such a file

included running multiple linear regressions of MCD level land use
                                      41

-------
against MCD level employment.  While the correlations obtained

were statistically quite good  (R-Square -  .96, or 96% of the var-

iation in employment was explained by land use), they were not

useful as the best predictor of employment at the MCD level was

high density residential.  Additionally, the constant was a negative

number (-147).  When the resulting equation was applied to the land

use data, many rural towns came out with negative employments.

Many modifications to the original regression were tried including

doing separate regressions for each subregion and eliminating residen-

tial land use as an independent variable.  In no case was a good reg-

ression obtained that did not result in many TAZ's with negative employment

     The  search for an alternative employment file resulted in

CDRPC Borrowing the Capital District Transportation Committee's

      This  data was  not complete.   Some of the omissions were:   Self-

 employed people,  farmers,  small post offices, some employers of less

 than  25  people, certain school districts, etc.   Additionally,  the

 data  came  with the  following conditions:

      The file  will  be returned when CDRPC has completed its  analysis.
      No  permanent copies of the file will be made.
      None  of the  file information will be released or published
      without NYSDOT approval.

      The file  was corrected for omissions as follows.  The  first step

 was to allocate the self-employed people  and unpaid family members.

 The 1970 census contained  information on  the number of self-employed

 persons  and unpaid  family  members by census  tract of residence.   Since

 many  of  these  people work  at home or in adjacent offices, it was as-

 sumed that the number of self-employed people and unpaid family  mem-

 bers  working in a tract was the same as the  number living in the tract.

 These people were allocated to the TAZ's  in  each tract on the  basis

 of the population of each  tract.

      The second step was to allocate farmers according to the  amount

 of agricultural land in each tract.   The  number  of farmers to  be al-

 located  was obtained by subtracting the agriculture,  mining  and  for-

 estry employment  on the CDTC file from the 1970  agriculture  and

 mining employment from CDRPC Technical Report 500-4,  Population,

 Income and Employment Forecasts for the Capital  District Region.

      The employment for each school in the omitted school districts

 were  then  added to  the  appropriate TAZ.   These employment figures

 were  obtained  from  CDRPC Technical Report 500-1  School Districts

 in the Capital  District Region.

      Having no  information  on  the specific location and number of

 employees  of any  other  omissions,  the  following  allocation method

was utilized.                         43

-------
     A)   The total file employment for each municipality was
     obtained by adding up each TAZ in each municipality.  This
     was compared to the MCD level figures in the RDP appendix
     and the number of employees not reported for each munici-
     pality was noted.

     B)   The total file employment by each of the nine industry
     groups was computed by addition of each employment group
     for every TAZ.  The 1973 employment by industry was ob-
     tained by interpolating between the 1970 and 1980 employ-
     ment figures in CDRPC Technical Report 500-4 Population. .
     .  .  The interpolation was done so that the total of the
     employments by industry equaled the total of the employ-
     ments by MCD or 291,630.

     C)   A computer program was devised which printed out the
     number of employees per acre of land use for each TAZ and
     indicated when there was land use with no employment assoc-
     iated with it.  The ratios used were:

      Commercial employment to commerical land use
      Service+government+fincance employment to institutional land use
      Manufacturing employment to manufacturing land use
      Transportation, Communication employment to transportation land

      D)  The average uncounted employment per acre of unused
      land for each type of land use was calculated and this
      information combined with the total numbers of uncounted
      employees by group and uncounted employment by MCD was
      used along with land use information including CDRPC Tech-
      nical Report 500-2 Shopping Center and Office Building
      Development in the Capital District Region to manually
      allocate employment to each TAZ so that the municipal
      totals and industry group totals for the Region were main-
      tained.

   The  output of this process was a listing of employment by in-

dustry  group by TAZ that was consistent with all known data.  A

sample  page of this output with the TAZ and Census Tract identifi-

cation  removed as per our confidentiality agreement with NYSDOT is

in the  appendix to this document.

     For the year 2000, CDRPC has MCD level employment projections

and Regional level industry group employment projections as well

as UTM  grid cell building block change information.  In this case

"CHGEMP" (change in employment) was calculated for each industry

                                     44

-------
and each MCD.  The building block changes were apportioned to each




TAZ in an MCD as in the population work.  Once this was completed,



the Regional employment by industry group in the file was computed by



addition of the number in each TAZ and differences between the



industry totals from CDRPC Technical Report 500-4 Population. .  .



and those in the projected file were rectified by a manual correction



process that maintained the correct MCD level employment totals.



     There are no MCD level employment projections  for 1980 or  1990.



These will be developed from the 1970 and 2000 employment files



generated by this project.
