                              INTRODUCTION

          This report is a summary of the  work performed  by  GEOMET,
Incorporated under Task 2 of Contract Number 68-02-0042 for  the  Environ-
mental Protection Agency (EPA) in conjunction with  the Environmental
Quality Board (Junta De Calidad Ambiental)  of the Commonwealth of
Puerto Rico.
          The results of this work provide a detailed commonwealth-wide
emissions inventory of particulate, sulfur oxide, hydrocarbon, carbon
monoxide, and nitrogen oxide sources of atmospheric pollution.
          The emissions inventory resulting from this task is considered
representative of calendar year 1970.  The data represent realistic
estimates of emissions but should not be interpreted as absolute values.
The basis for the raw data was questionnaries on individual  sources with
information on the questionnaires being written either by Puerto Rico
air pollution agency personnel, based on personal interviews, or by the
involved firms replying to a written solicitation for data.
          The Puerto Rico Environmental Quality Board (EQB)  has  a  file
of over 2000 sources; questionnaires are filled out in varying degrees
of completeness on each source.  An additional 110  sources were  solicited
for data by GEOMET.
          Using these data, GEOMET selected 342 sources for  point  source
processing based on a minimum of 10 tons per year emissions.  These
sources were coded in detail and processed as point source data.   Addi-
tional data on commonwealth-wide fuel usage, vehicular traffic,  waste

-------
disposal, solvent evaporation, vessel  traffic,  aircraft activity,  and
sugar cane field burning were collected and processed as area  sources.
          Detailed computer processing results  are provided separately
from this report.  A summary of these  data is  provided in Section  2.0
of this report and in the detailed summary table  shown in Appendix A.
Section 3.0 provides a description of  the task  performed by GEOMET.
The description of the study area and  a definition of the grid coordinate
system used are provided in Section 4.0.   Details  of the methodology
employed by GEOMET in accomplishing this  task  are  given in Section 5.0.
References used in this work are shown in Section  6.0.  Appendix B pre-
sents a listing of the political jurisdictions  of  Puerto Rico, and
Appendix C presents a point source data coding form.
          This report reflects comments and suggestions made by the EPA
and the EQB as a result of an earlier  (August  16,  1971) draft  report on
the detailed emission inventory for Puerto Rico.

                                SUMMARY

          A detailed summary table, similar in format to the-requirements
of Appendix D of the August 14, 1971 Federal Register, of emissions in
Puerto Rico is shown in Appendix A.  This section briefly summarizes the
emissions and provides a pictorial view of the percentage distribution
of them by use of pie charts.
          The estimated annual  emissions for Puerto Rico determined from
the commonwealth-wide emissions inventory are:
              Particulates                  95,195 tons
              Sulfur Oxides                144,533 tons
              Carbon Monoxide              600,876 tons
              Hydrocarbons                 116,235 tons
              Nitrogen Oxides              117,762 tons
          Table 1 provides a summary of these pollutants by source
category.  This table is similar in format to the Appendix G require-
ments of the August 14, 1971 Federal Register.
          Figure 1 shows the percentages, by source category, of emis-
sions represented by the data in Table 1.
          The following paragraphs present a brief discussion of the
emissions.
          Particulates:  Point sources were responsible for the highest
percentage of particulate emissions (90%) with  area sources contributing
the remaining 10%.  Industrial process sources  made the largest contri-
bution.

          Sulfur  Oxides:   Individual point sources  contributed 83% of
the sulfur oxide  emissions with area sources  contributing the remaining
17%.  Fuel combustion sources contributed 92% of  the sulfur oxide
emissions.  The fuel  sources (92%) were composed  of individual com-
mercial-institutional-industrial sources (40%)  and  steam-electric power
plants (52%).  The  power  plants are thus the  largest single group of
sulfur oxide emitters.  Transportation sources  contributed 6% with
process sources contributing less than 2%.

          Carbon Monoxide:  Area sources contributed 90% of the carbon
monoxide emissions; transportation sources were the largest contributors
and accounted for 85% of the commonwealth-wide total.   The next largest
area source contribution was open burning with 5% of the total.  Point
sources contributed 10% of the total, with industrial  process  sources
providing almost all of this contribution (9.7%).

          Hydrocarbons:  These emissions consisted of 88% from area
sources and 12% from point sources.  Transportation sources accounted
for 76% of the total, open burning 9%, and process sources (primarily
refineries) 11%; the remaining 4% came from fuel  combustion (2%)  and
miscellaneous sources (2%).

          Nitrous Oxides:  These emissions came from area sources (60%)
and point sources (40%).  Transportation sources  accounted for 53% of
the total nitrous oxide emissions, and point source fuel combustion
accounted for 39% of the total; process losses (6%) and solid  waste
disposal (2%) accounted for the bulk of the remainder of these
emissions.
          Table 2 is provided to show the level of pollutant emissions
for each municipality.  These emissions are totals, including  both
point and area sources.

                            TASK DESCRIPTION

          The purpose of the task performed by GEOMET in conjunction
with the Environmental Quality Board of the Commonwealth of Puerto Rico
was to produce a detailed emission inventory of Puerto Rico for the
following pollutants:  particulates, sulfur oxides,  carbon monoxide,
hydrocarbons, and nitrous oxides.
          A meeting was held on May 7, 1971 among the EQB, EPA, and
GEOMET to detail responsibilities for task completion.  The following
is a summary of the work agreed upon at that meeting.
          The Department of Health of the Commonwealth of Puerto Rico
had recently completed the collection of emission inventory information
for approximately 2000 sources throughout the Commonwealth.  As described
by the agency, it appeared that the available information could serve
as an excellent data base for the purposes of developing an implementation
plan.  However, four distinct work areas existed before the data could
be finalized and tabulated into a usable format:
          1.  Data must be collected for an additional  100 sources,
including all Federal  facilities.   In addition,  some of the 2000 source
forms are incomplete and some contacts may be required  to collect the
remaining data.
          2.  The available data are representative of  1969 and in most
cases will be applicable for 1970.   Changes in some process sources  have
taken place, therefore, updating of specific sources will  be required.

known changes.
          4.  The data, both for point and area sources,  should be
recorded for computer processing and processed at the EPA facility with
results given to the EQB and the EPA.

                               STUDY AREA

4.1  DESCRIPTION OF STUDY AREA
          The Commonwealth of Puerto Rico consists of 77 municipalities
and covers an area of 3,423 square miles; the population of Puerto Rico
as of January 1970 was 2,801,400.  The main island has 75 municipalities
with the Islands of Culebras and Vieques being the remaining two.
Figure 2 shows the outline of the island and the municipalities  as of the
end of 1970.
          Temperatures within Puerto Rico maintain an average of 75°F in
the winter and 80°F in the summer.  The trade winds prevail  on the island
from the east, northeast, and southeast.
          Puerto Rico comprises  one Air Quality Control  Region (AQCR).
The 77 municipalities are in AQCR 244.   Appendix B lists the municipal-
ities with  assigned political  jurisdiction numbers.   The numbering
system is grouped alphabetically into Health Regions  (Puerto Rico  system).

4.2  GRID COORDINATE SYSTEM
          A grid coordinate system based on the Universal  Transverse
Mercator Projection (UTM) for Puerto Rico was selected at the initial
meeting.   Maps, utilizing tick marks with this sytem, were obtained
from the Department of Public Works in San Juan.  These maps, 1:20,000
scale, were mapped, edited, and  published by the Geological  Survey complying
with National Map accuracy standards.  The reference  point is the  same
for all areas of Puerto Rico, and all coordinates are positive.   The  grid
systems and coordinates are illustrated in Figure 2.

                             METHODOLOGY

5.1  GENERAL APPROACH
          The following is a general description of the approach used
in this task to obtain the required emissions inventory.   Sections  5.2
and 5.3 provide more details on the specific methodology for point  and
area sources, respectively.
          The Air Pollution Control Program of the Puerto Rico Depart-
ment of Health had already collected, through personal  interviews,  data
on over 2000 sources in Puerto Rico.  These data are on questionnaires
and represent all types of commercial, institutional, and industrial
sources.  An additional 110 sources were contacted by letter and asked
to supply data by filling out questionnaires.  These data were separated
into two groups.  One group was sources having more than 10 tons of
emissions per year or representing specified industries named in
Appendix C of the August 14, 1971  Federal  Register with no lower cut-off
point.  These were the sources selected for coding for the point source
inventory.  Emission calculations  were made for all process sources
using emission factors in the EPA publication, Compilation of Air Pollu-
tant Emission Factors  (McGraw and Duprey 1970), or specified factors
supplied by the EQB.  Combustion source calculations were made by the
EPA computer program based on type and quantity of fuel and the sulfur
content of the fuel.
          The data for 342 point sources (not all  individual firms) were
coded and processed  by the EPA point and area source computer program at the
Research Triangle Facility.

-------
          The second group of point source forms representing minor
sources and sources with incomplete data was coded with whatever avail-
able information appeared on the forms.   No recontacting of these sources
was attempted.  These data were card punched in the point source format
and listed by computer to provide a record of the available information
on these approximately 1700 minor sources.  These cards were not pro-
cessed on the EPA program since fuel consumption and process weight
information was incomplete.
          Material processed or consumed on the island which could not
be attributed to specific point sources  was included in area sources.
These data include fuel  usage for commercial, institutional, and indus-
trial sources (residential heating is nonexistent); open burning of
waste material; solvent evaporation from dry cleaning operations; diesel
fuel usage by seagoing vessels; diesel  fuel used by vehicles; LPG (propane
and butane) use; gasoline usage by vehicles; sugar cane field burning;
and aircraft activity at airports.  These consumables were allocated  to
each municipality (procedures described  in Section 5.3) and coded, key-
punched, and processed on the EPA area   source program.  A second area
source compilation was made for the greater San Juan area.  The  eight
municipalities included in this second  grouping were:  San Juan, Carolina,
Trijillo Alto, Guaynabo, Bayamon, Toa Alta, Toa Baja, and Catano.  Orig-
inally, Rio Piedras was  coded as a separate municipality;  it has,  in
fact, been merged into the San Juan municipality.   The  numbering system
shown in Appendix B was not changed as  it would confuse earlier  work.
A grid system consisting of 62 grid squares was developed for this area.

-------
The system consisted of 43 grid squares 2 kilometers on a side (4 sq.
kilometers) and 19 grid squares 4 kilometers on a side (16 sq. kilometers)
This system is illustrated in Figure 3.  Data for this grid system were
developed to further delineate the emission picture in the San Juan area
but are not additional emissions over those shown for the municipality
by municipality results.
          A third area source compilation was made for the Ponce area.
A grid system comprised of 24 grid squares was set up for Ponce and is
illustrated in Figure 4.
          The results of the point source and area source emission inve-
tory calculations are available separate from this report at the EPA-OAP
Surveillance section, the EPA Region II office, and at the EQB office
in Puerto Rico.  A detailed summary of these results is provided in
Table A-l of Appendix A of this report.  Sections 5.2 and 5.3 present
more details of data sources and procedures for point and area sources.

5.2  POINT SOURCES

5.2.1   Obtaining of Data
          The basic source of data on point sources was the question-
naires on file at the APCP (now at the EQB) or those additional onei
acquired by the GEOMET mailing.  Recontacts were made to sources for
which file data were insufficient, but needed.
          All  power plants come under one agency, the Puerto Rico "Water
Resources Authority."  This agency provided updated data on all power
plants.

5.2.2  Calculations
          Each point source selected for inclusion in the point source
emission inventory was first examined as to the manner in which emissions
occurred (process or combustion).  A given firm might have several  sources
and might have both process and combustion sources.  Each emission  source
at a given firm was coded as a separate source.
          Process source calculations were made based on the type of
process, the process weight rate, and the EPA emissions factor book
(McGraw and Duprey 1970).  Hand calculations were made on the basis of
uncontrolled emissions; if a control device was available, it was coded
and the computer program calculated the controlled emissions.
          Combustion source calculations were made by the computer  pro-
gram based upon the type and quantity of fuel burned and the sulfur
content of the fuel.
          One source type was coded uniquely for that source:  Sugar
mills burn bagasse (a sugar cane residue), thus bagasse is a fuel type.
However, the coding format did not allow for coding bagasse burning as
a fuel  usage; therefore, bagasse burning was coded as a process source,
using process weight rates equal to the burning rate and hand calculat-
ing the emissions.  Emission factors for bagasse burning were provided
by the EQB, based upon incineration of agricultural refuse.  Sufficient
data on bagasse burning to better quantify emissions are not available.

          Source Number (Columns 1-3).  Each source of emissions  was
assigned a source number.  The computer program requires that source
numbers be sequential starting with 1 and be no greater than 999.
          Region (Columns 4-6).  This identifies the specific AQCR
involved.  All of Puerto Rico is in AQCR number 244.
          SIC (Columns 7-10).  Standard industrial  classification iden-
tifies the type of industry to which this source belongs.  The EPA
furnished the list of SIC's to be used.
          Site (Columns 11-13).  This was used primarily to identify
multiple sources at a given location.
          Process Code (Columns 14-15).  The process code was used to
identify the type of process or combustion source used based on a list
provided by EPA.  If a 1-9 value was used in Column 15 it identified a
process source.
          Description Name (Columns 16-38).  These  spaces were used to
identify the source by the name of the firm and any other descriptor
used.
           Coordinates (Columns 39-47).  The X and  Y coordinates  relate
to the location of the source to the nearest 100 meters in the grid
coordinate system used.  Each source coded was located, to the best of
the information available, on the maps (1:20,000 scale) described

-------
previously, and the coordinates were read.  In many cases these coordi-
nates are only approximate due to the difficulty in locating the point
with the information available.
          Political Jurisdiction (Columns 48-49).  The municipality
within which the point source was located determined the political
jurisdiction.  See Appendix B for the list of political jurisdiction
numbers.
          Owner (Column 50).  The owner of the source was identified
as to private (1), local (2), commonwealth (3), federal (4), or a
utility (5).
          Type (Column 51).  The source type was coded as a process (1),
fuel combustion (2), or solid waste disposal (3).
          Operating Hours (Columns 52-55).  The hours of operation
specified on the questionnaire were coded here.  It is possible that
these stated operating hours are the hours that the firm is operating
but may not necessarily be the number of hours that material is pro-
cessed or fuel is consumed.
          Stack Parameters (Columns 56-79).  Details of the stack height,
diameter (at the exit), temperature, velocity of discharges, gas volume,
and plume rise were entered here as available and as appropriate.
          Process Weight (Columns 4-19).  The normal (stated) process
weights were converted to process weight rates by dividing the annual
processing quantity by the number of operating hours.  If a maximum
process weight rate was obtainable (or applicable)  it was calculated.
If unavailable or inapplicable the maximum process  weight rate was
coded equal  to the normal process weight rate.

-------
          Maximum Boiler Capacity (Columns 26-30).   If a maximum boiler
capacity was obtainable for a fuel combustion source it was coded in
Bill's per hour.  If unobtainable it was coded equal  to the normal boiler
usage rate.
          Fuel Usage (Columns 33-39. 42-48. 51-56.  and 59-64).   The
type of fuel used by a combustion source was determined to be coal,
residual oil, distillate oil, or natural gas.  The  quantity of fuel
burned per year was then coded.  Natural gas is not used in Puerto Rico;
however, if a source burned LPG it was coded as natural gas since no other
fuel coding space was available.  The emission factor sets utilized for
each fuel source were determined from a list provided by the EPA and
listed at the beginning of each point source printout.
          Heat Content (Columns 59-79).  The heat content of each fuel
was coded as either the value shown on the source questionnaire (if avail-
                                                              3
able), or if no value was given, the following heat values (10  BTU/gallon)
were used:   residual (150) and distillate (140).
          Percent Ash-Coal (Columns 4-6).  This was  not used since coal
was not used as a fuel.  Coke was used as a fuel  in some sources and
coded as coal.
          Sulfur Content (Columns 7-20).  The sulfur content, in percent
sulfur by weight, was coded for each fuel.  If a  sulfur content was
specified on the questionnaire it was used.  If unspecified, the follow-
ing percentages were used:  kerosene #1 (0.5), diesel #2 (1.0), Navy
special #5 (2.5), and Bunker C #6 (2.5).

-------
          Control Efficiency (Columns 21-27).  If a source had a con-
trol device for particulates or SCL, the control efficiency was deter-
mined and coded as a percentage and identified by type in Columns 28-30.
          Hand Calculated Emissions (Columns 38-67).   The emissions for
all process sources (plus bagasse burning) were calculated based on the
process type and quantity of material processed.  Emission factors were
determined from the EPA factors book (McGraw and Duprey 1970).  Calcu-
lations were made and coded as uncontrolled emissions.
          Allowable Emissions (Columns 68-79).  These spaces were pro-
vided to input the emissions allowed by commonwealth  regulations.  Since
no such regulations currently exist, these spaces were not used.
          Comments (Columns 4-79).  The D card, normally used only for
pertinent comments, was also utilized to record in Columns 4-16 the
particulate and sulfur oxide emission limitations recommended by the
April 7 Federal Register.  Columns 17-79 were then used for comments.

5.3  AREA SOURCES

5.3.1  Obtaining of Data
          Area source data were collected for:  fuel  usage by commercial,
institutional, and industrial  firms; open burning of  waste; solvent evap-
oration from dry cleaning establishments; seagoing vessels; diesel burn-
ing vehicles;  gasoline usage for vehicles; LPG use; sugar cane field
burning; and aircraft activity at airports.

-------
          The APCP had already collected some area source data, primarily
 for  1969.  These data were updated to 1970 where possible.  The follow-
 ing  paragraphs detail the sources of the area source data and provide a
 summary of the data.
          Fuel Usage.  The following data were obtained from the
 Puerto Rico Office of Economic Indices:

          Motor Gasoline                               426,528,000 gal
          Aviation Fuel                                    102,910 bbl
          Kerosene                                         990,347 bbl
          Solvent                                            4,975 bbl
          Diesel Fuel Oil - Industrial Consumption       1,684,488 bbl
                          - Int. Bunker (vessels)          147,422 bbl
          Residual Fuel Oil - Industrial Consumption    16,591,015 bbl
                            - Int. Bunker (vessels)        389,872 bbl

          The above fuels represent fuel sales in Puerto Rico in 1970
 and  thus include fuel used in point sources (except for use at refineries)
 The  Bureau of Mines report which lists fuel consumption by states does
 not  include Puerto Rico nor is information available from the American
 Petroleum Institute.
          Open Burning.  Data were supplied by the EQB on refuse disposal
 by open burning dumps.  These figures do not include incineration at
apartment houses,  or commercial  and industrial  installations.   These
latter data are currently being compiled by the EQB but were  not avail-
able to this  study.   Data available on open burning show 1869  tons/day
burned or 682,185  tons/year.

-------
          Solvent Evaporation.  Solvent evaporation from dry cleaning
establishments was estimated by assuming 13 Ibs of clothes cleaned per
capita per year in the warm Puerto Rico climate.  The EPA emissions
factor book suggests 18 Ibs/capita in moderate climates and 25 Ibs/
capita in colder climates.  The APCP agreed that 13 Ibs/capita was a
reasonable assumption.  Using the population of 2,801,400 and the
solvent evaporation factors of the EPA reference (McGraw and Duprey 1970),
the solvent evaporation was estimated to be 2776 tons/year.
          Vessels - Diesel.  Personnel of the EQB determined the fuel
use by vessels while in port based upon:  volume of traffic; tonnage
of traffic; an average number of ships in port/day (for each port); an
average port stay of 1.5 days; a fuel usage of 3696 gallons per motor
vessel in port per day and 9,576 gallons per steamer in port per day.
The basic vessel data were obtained from the Puerto Rico Ports Authority,
Office of Economic Research Report.
          Diesel Motor Vehicles.  These data were obtained directly from
individual petroleum products manufacturers and distributors contacted
by the EQB.  These data show 28,500,000 gallons of diesel oil sold in
Puerto Rico in 1969 to be used for highway transportation.  Data for
1970 were not available for this study.
          Gasoline Motor Vehicles.  Sufficient data on traffic flow
volumes were not available.  It was determined from the Office of Economic
Indices that 426,528,000 gallons of motor vehicle gasoline were consumed
in Puerto Rico in 1970.  Assuming 12.5 miles per gallon this gives
5,331,600,000 vehicle miles for 1970.  This total was split into 3,625,488,000

-------
vehicle miles for urban driving and 1,706,112,000 vehicle-miles for
rural driving based upon the ratio of registered vehicles in urban and
rural areas.
          LPG Usage.  The Puerto Rico Office of Economic Indices reported
the following sales of LPG in Puerto Rico in 1970:

          Butane                                  837,285 bbl
          Propane                               1,443,952 bbl
          Other LPG                                51,670 bbl

These fuel usages were recorded as #19 on the area source fuel  list in
units of 1000 gallons, noted as "other" on the computer printout; emis-
sions are given in tons/year.
          Sugar Cane Field Burning.  Data on sugar cane field burning
in 1970 were obtained from the administrator of the Sugar Rehabilitation
Program.  In 1970 it was estimated that 190,000 acres  of sugar cane were
planted.  Approximately 75 percent of the acreage is burned to remove
unwanted foliage.  This means that 143,000 acres of sugar cane are burned.
These data were recorded in acres burned as #22 on the fuel totals sheet
noted as "other" on the computer printout sheet; emissions are given in
tons/year.
          Aircraft Activity at Airports.  Aircraft activity at each
airport in Puerto Rico was determined by EQB personnel  based upon data
supplied by the Puerto Rico Ports Authority.  Table 3  shows the number
of landing-takeoff cycles (flights) or LTO's determined for each air-
craft type.   The emissions from this aircraft activity were hand

calculated and entered on the  area source  sheets in  Column 1  emissions
for the  municipalities of Carolina, Ponce,  and Mayaguez, respectively.

5.3.2  Adjustment  of Fuel Totals
           The fuel  totals shown in Section  5.3.1 include fuel  consumed
by point sources that are considered in  the point source inventory.
Thus this fuel must be subtracted from the  commonwealth total  before
the input for the  area source  data deck  is  determined.   The fuel  of
each type consumed by point  source is available as an  output  of  the
point  source emission inventory.


-------
          The point source results show that 654,914,000 gallons of
residual and 250,844,000 gallons of distillate oil were consumed by
the point sources.  However, part of the point source total was con-
sumed by refineries, which used fuel not already included in the com-
monwealth totals.  Residual fuel for industrial point sources to be
subtracted from Puerto Rico totals is 643,644,000 gallons, leaving
53,179,000 gallons for allocation to area sources.  Commercial and
institutional residual totals remain unchanged at zero (0) gallons.  Indus-
trial point source distillate oil to be subtracted is 42,845,000 gal-
lons, leaving 27,903,000 gallons for area source allocation.  Commercial
and institutional distillate oil usage to be subtracted is 1,864,000
gallons, leaving 39,731,000 gallons to be allocated to area sources.
          LPG usage by industrial sources was 14,335 x 10  cubic feet.
This usage was almost all by petroleum refineries, therefore, this point
source LPG usage is not subtracted from the previously given island-wide
LPG use.  Thus 97,982,000 gallons of LPG is allocated to area sources.

5.3.3  Emission Factors
          The emission factors used for area sources were provided by
EPA in the area source format for all but LPG, sugar cane field burning,
and aircraft emissions.
          The LPG emission factors used (LPG in the coding is fuel group
19) are a weighted average between butane and propane factors found in
McGraw and Dupreys1 Compilation of Air Pollutant Emission Factors, 1970
weighted by the quantity of each.  Thus the LPG emission factors used
are:  particulates, 6.3 pounds/10  gallons; sulfur oxides, zero (0);

-------
                              3                                     3
carbon monoxide, 6.6 pounds/10  gallons; hydrocarbons, 2.6 pounds/10
                                           3
gallons; and nitrous oxides, 35.0 pounds/10  gallons.
          Sugar cane field burning factors were obtained from McGraw
and Duprey (1970) and are:  0.113 tons/acre for particulates; zero (0)
for sulfur oxides; 0.75 tons/acre for carbon monoxide; 0.15 tons/acre
for hydrocarbons; and 0.015 tons/acre for nitrous oxides.
          Aircraft emission factors were not input to  the  data as these
emissions were hand calculated.  The factors used are  found in McGraw
and Duprey (1970).

5.3.4  Apportioning Factors
          The apportioning factors for the consumables considered for
area source allocation are shown for each municipality and grid square
in Table 6-1 of the computer listing (not included in  this report) for
each area source data run.  The following paragraphs will  specify the
basis for each apportioning factor set but will not repeat the factors
available in the computer printout.  Factors were basically determined
using the methods of Bierbaum and Gedgaudas (undated).

          Factors 1-3:  Residential Fuel.  No factors  were used since
residential fuel is not used.
          Factors 4-7:  Commercial and Institutional Fuel.  Bierbaum and
Gedgaudas specify that the ratio of retail and wholesale employees should
be used in determining the allocation factors for this group.  The usual
source of data for the factors is in the yearly census of business for
retail trade and for wholesale trade for a given state, published by

-------
the U.S. Department of Commerce.  These publications were not available
for Puerto Rico.  However, the Office of Labor Statistics of the Puerto
Rico Department of Labor publishes an annual listing of manufacturing
establishments in Puerto Rico.  The October 1969 issue (Estado Libre
Asociado de Puerto Rico) was the latest issue available.  The number
of commercial businesses in each municipality was determined from this
reference and used as the apportioning factors for Factors 4-7.
          Factors 8-11:  Non-Point Source Industrial Fuel.  Again
Bierbaum and Gedgaudas recommend a Bureau of the Census document on a
census of manufacturers to get the number of manufacturing employees.
This was not available for Puerto Rico.  The annual  listing of the
Puerto Rico Department of Labor was used to determine the number of
industrial  firms in each municipality.  The number of industrial firms
was used as the apportioning factor.
          Factor 13:   Open Burning.  Open burning totals were established
on a per capita waste accumulation basis.  Population is used as the
apportioning factor for each municipality to allocate open burning.
          Factor 15:   Solvent Evaporation.   As in Factor 13, population
is the apportioning factor for solvent evaporation.
          Factor 16:   Vessels.  The quantity of fuel used for this source
was based on the number of ships in port.  Thus the  apportioning factor
used is the number of ships in port in a given municipality.
          Factor 18:   Diesel Motor Vehicles.  The apportioning factor
is the number of diesel burning vehicles registered  in a given munici-
pality.

-------
          Factor 19;  LPG Usage.  The LPG usage was primarily by commer-
cial and institutional users.  Thus the apportioning factors for LPG were
the numbers of businesses in a municipality.
          Factors 20-21:  Gasoline Motor Vehicles.  The number of auto-
mobiles, trucks, pickups, government vehicles, motorcycles, and busses
registered in each municipality was obtained for 1970 from the Depart-
ment of Public Works, Bureau of Motor Vehicles.  First a determination
was made for a given municipality to see if it was all urban (thus
25 mph traffic) or all rural (thus all  45 mph traffic).  This was based
on the percent of urban or rural area in the municipality.  For those
municipalities having a significant mixture of urban and rural (mostly
rural), the vehicle registration was used.   In these cases automobiles
were considered as 45 mph traffic with the remainder of the vehicles
as 25 mph traffic.  Thus the apportioning factors were the numbers of
vehicles in each speed category registered in each municipality.
          Factor 22:  Sugar Cane Field Burning.  The number of acres
of sugar cane burned in each municipality was estimated and used as the
apportioning factor.

                     EMISSIONS INVENTORY SUMMARY

          The computer printout for the point and area source emission
inventory give detailed results for each source and each municipality.
Table A-l is provided to present a detailed summary of emissions in a
form similar to that specified in Appendix D of the August 14, 1971
Federal Register.  This form is as similar to the suggested Appendix D
format as can be made with the existing computer printout format.  It
differs from the suggested format in that the suggested categories of
Commercial-Institutional Fuel Combustion and Industrial Fuel  Combustion
are grouped into one category, Commercial-Institutional-Industrial Fuel
Combustion.  The other major difference is that process losses in
Table A-l can not be broken out into the categories suggested by
Appendix D due to the nature of the computer printout.
          Space for additional entries under allowed emissions is
provided on Table A-l to facilitate the addition of control strategy
data as these data are developed for the implementation plan  in another
task.
          Puerto Rico is suggested as Priority III for CO, HC, and
NOX, thus control strategies will  not be developed.  Control  strategies
will be developed for particulates and sulfur oxides.

                 PUERTO RICO POLITICAL JURISDICTIONS
          Puerto Rico is subdivided into municipalities.   For coding
purposes, a political jurisdiction number has been assigned to each
municipality on the main island.  This enables a summary  of emissions
by municipality.
          Previous work in Puerto Rico considered five  health regions.
Although this has no necessary relationship to the AQCR,  it was  decided
to number the municipalities alphabetically by health  regions.   This
numbering is shown in Table B-l.  A further island-wide alphabetical
listing is shown for convenience in Table B-2.
