             I.   PROJECT BACKGROUND AND SCOPE

      Environmental  Protection Agency  (EPA)  regulations  for  the
storage and transfer of gasoline require bulk plants  in  certain
specified air quality control  regions  to control  hydrocarbon
emissions from their operations.   Vapor recovery  systems  are to
be installed and operated in  a manner  that will prevent  release
to the atmosphere of no less  than 90 percent by weight of organic
compounds in vapors  generated during gasoline transfer operations.
Individual states have submitted control strategies in State
Implementation Plans and enacted laws  which  frequently provide
for the exemption of small  bulk plants from  hydrocarbon  emissions
control regulations.  Conditions for granting these exemptions
are not uniform among the states, e.g., throughput limits oftfcn
differ.  The rationale for allowing exemptions has generally been
based on the anticipated adverse economic  impact  to the  industry
or on the estimated minor contribution of  bulk emissions to  the
area wide hydrocarbon/oxidant levels.
      In order to determine whether Federal  vapor recovery regu-
lations need revision, the Division of Stationary Source Enforcement
(DSSE) contracted with Pacific Environmental Services,  Inc.  (PES)  to
perform a preliminary investigation of the impact of vapor recovery
regulations on small bulk plants.  This first study focused  on  bulk
plants in the San Joaquin Valley and San Diego California areas  and
the Denver, Colorado area.  The results of this  task, reported  in
"Economic Analysis of Vapor Recovery Systems on  Small Bulk Plants,"
describe the following aspects of gasoline bulk  plants.

            1.   Average gasoline throughput  and range of
                throughputs.
            2.   Average cost  of installing bottom loading vapor balance
                systems on the bulk plant  tanks,  loading rack
                and trucks.
            3.   Financial profiles of  classes of  bulk plants.
            4.   Short term economic impact of installing vapor
                control equipment.
                                                                        1-1

This current study is a similar survey of bulk plant operations

in the specific areas surrounding Baltimore, Md.  and Washington,

D.C, and Houston/Galveston, Tx,  It is being performed to determine

whether the descriptive, market and economic data presented in the
earlier report can be adequately applied to other areas of the
country.   Therefore the tasks to be completed are quite similar:
                      •
            1.  Provide an inventory of bulk plants.
            2.  Describe facilities and vapor recovery
                equipment at the bulk plants.
            3.  Classify these bulk plants by through-
                put.

            4.  Determine types of customers and
                volume dispensed to non-exempt accounts,
                agricultural accounts and accounts with
                small tanks.
            5.  Determine the financial profile of typical
                bulk plants.

            6.  Estimate the long and short term  economic
                effects of installing and maintaining
                vapor recovery equipment, particularly
                with respect to the number of anticipated
                plant closures or plant start-ups.
            7.  Estimate emissions from bulk plant opera-
                tions and the decrease in emissions if
                controls are adopted.

      All  information obtained in these tasks is  to serve as a basis

to determine  if there is a specific gasoline throughput
below which gasoline bulk plants should not be required to  install

vapor recovery systems for incoming or outgoing gasoline shipments.
                                                                        1-2

                         II.   SUMMARY

      Inventories of gasoline bulk plants  were  generated  for  the
Baltimore and National  Capital  AQCRs  (56 plants)  and for  the
Houston/Galveston AQCR  (70 plants),   Similarities between these
plants and facilities in the San Diego and San  Joaquin Valley
areas of California and the Denver,  Colorado area, which  were
inventoried by PES in an earlier study (1), were  examined by
comparing storage capacity, number of delivery  trucks, gasoline
throughput, volume of other products and services, types  of cus-
tomers, vapor recovery system costs and their financial impact.
A comparison of plant operations in these  four areas is given in
Table II-l.
       A typical  bulk plant,  covered  in this  inventory, would be a
 wholesale gasoline distributor who  receives  his  supply solely by
 truck and has  an average  plant throughput of about 5,000 gallons
 (20,000 1.)  per  day.   The  bulk plant provides  direct product
 delivery to  the  customer  and is usally located in or near a  small
 town rather  than in a  large  urban area.   Although bulk plants fre-
 quently market petroleum  distillates other than  gasoline, this study
 has been limited to the gasoline marketing segment of the industry.
 Hydrocarbon  emissions  from such plants are associated with (1) trans-
 fer of gasoline  from the  delivery trailer to storage tanks at the
 bulk plant,  (2)  breathing losses from daily temperature  changes
 at the storage tank, (3)  transfer of gasoline  from the storage
 tank to the  bulk plant delivery truck, and (4) miscellaneous events
 such as spillage and leakage at valves, hatches  and piping joints.
 Emission controls are  designed to recover the  vapors displaced from
 the empty storage tank and return them to the  delivery trailer or
 to recover the vapor displaced from the empty  bulk plant delivery
 truck and return them  to  the plant storage tank.  Breathing  losses
 can be reduced by using pressurized tanks.
                                                                          II-l

-------
      Although bulk plant optr«t1ons are basically quite similar
in these several  areas of tht county, there are some noteworthy
regional differences.
      First, the  average daily gasoline throughput at a bulk plant
in Houston/Galveston is significantly greater than in other parts
of the country.  Also, more of that gasoline is going to non-exempt
accounts.  This increases the potential amount of emissions a given
uncontrolled plant could generate during routine operations.
      In all areas studied, most of the gasoline is delivered from
the bulk plant to accounts with small tanks, i.e., less than 2000
gal capacity (7600 1.).  Also, 1n all areas, a reasonably large
portion of that gasoline reaches agricultural users.  One reason
so much gasoline  dispensed through bulk plants does go to small
accounts is that  customers with larger tanks, which would be non-
exempt, are able  to receive delfveries directly from transports
which have been loaded at terminals.
      Average storage capacity in the Denver area is less, which
means more frequent deliveries.  It should also be noted that only
a few plants have installed vapor controls for incoming gasoline
shipments in this area.
      The amount of underground storage around Baltimore and Washing-
ton, D.C. is substantial.  This is an effective means of reducing
tank breathing losses.  Also, plants in the eastern United States
deal much more heavily in distillates because so many people use #2
fuel oil for heating.
      Only in sections of California and around Houston/Galveston
has there been substantial progress in controlling hydrocarbons
emitted when bulk plants receive transport deliveries of gasoline.
Efforts to recover vapors when small delivery trucks are filled have
been minimal except near Houston/Galveston.
                                                                           II-3

-------
      The average cost to install a vapor balance system to recover
hydrocarbons from deliveries to the bulk plants was found to be
$3,500.  This corresponds with data previously reported (1, 2).
The cost and equipment requirements to recover hydrocarbons from
the filling of delivery trucks at the bulk plant loading rack have
not yet been suitably resolved.  This is primarily because two
distinct, different vapor recovery systems are being installed:
top loading vapor recovery systems and bottom loading vapor recovery
systems.
      The equipment being used in the Houston/Galveston area for
major oil company owned bulk plants appears to demonstrate that
top loading vapor recovery equipment is feasible, effective and
affordable.  The average cost of adapting a loading rack and an out-
going delivery truck at plants surveyed in this study was $7,000.
(Details are provided in Section IV.  To substantiate these data,
additional, more detailed investigations of the cost, equipment
requirements and system efficiency of top loading vapor recovery
systems are underway).
      Bottom loading vapor recovery systems will bt substantially
more expensive than top loading systems.  The only facility contacted
in this study which had installed a bottom loading system provided
these costs for work done in 1974:

            1}  converting the loading rack
                      $21,000
            2)  converting two small delivery trucks
                      $10,500
Bulk plants are paricularly interested in a bottom loading system
because, even though the initial expense can be much greater than  a
top loading system, modernizing the loading operation makes it simpler,
safer, faster and thereby potentially more profitable.
                                                                           II-4

-------
      If the bulk plant is found to be responsible for installing
vapor recovery devices on his customers'  non-exempt tanks,  the
operator could, at an average cost of $400 per tank, need to spend as
much as $20,000; whereas, a customer would be unlikely to have to
spend more than $2,000.
      Sufficient data on operating and maintenance costs were not
available for any meaningful discussion.
      The financial impact of vapor recovery regulations on a small
bulk plant depends primarily on the ability of the owner to obtain
funds for the initial investment in equipment.  Analysis indicates
the smallest size operation which could qualify for the loans needed
to purchase and install a top loading vapor balance system which
costs $10,000 for trucks, tanks and loading rack would have to have
an annual throughput of 600,000 gallons (2,300,000 liters).  This
study showed that 40% of the plants in the Baltimore and National
Capital AQCRs and 6% of the plants in the Houston/Galveston AQCR
have throughputs below this level.  An earlier study performed by
PES showed that 25% of the plants in the San Diego, San Joaquin
Valley and Denver AQCRs also have annual  throughputs below 600,000
gallons  (2,300,000 liters),  A spokesman for a major oil company
stated 1,000,000 gallons/year (3,800,000 liters/year) throughput
should be the minimum gasoline sales volume before a bulk plant
could be considered profitable.  Owners with business volumes between
these two numbers are going to have to make a business judgement
about how compliance with vapor recovery regulations will affect
them economically.  Bulk plant operators interviewed in this study
were asked what cost levels would constitute undue economic hard-
ships and thereby cause them to either close their bulk plant or
discontinue bulk plant gasoline sales.  Based upon these responses,
Table II-2 was prepared.  As can be seen, those facilities with
daily throughputs of less than 4,000 gal. (15,000 1.), which is
equivalent to an annual throughput of less than 1,040,000 gal.
                                                                           II-5

-------
(3,940,000 1.), would be those most likely to not be able to cope
with the economic stress imposed on them as a result of installing
vapor recovery.  An overall  closure rate of 25% is quite possible.
                                                                       II-6

                III.   BULK  PLANT  OPERATION

A.  INTRODUCTION TO THE INDUSTRY AND OVERALL  CHANGES  IN  THE
    INDUSTRY
      An industry overview has  been presented in  previous  reports
(1, 2); therefore, only a brief summary will  be given  here.
      A small bulk plant has been considered  to be a wholesale
gasoline distributor who receives his supply  solely by truck  and
has an average plant throughput of less than  20,000 gal/day
(76,000 I/day).    Although the bulk plants frequently also market
distillates, agricultural supplies or automotive  supplies, this
study has been intentionally limited to examine only the gasoline
distributing segment of the bulk plant industry.  Figure 1  is  a
schematic of the gasoline distribution network which relates  to
bulk plants.  The bulk plant functions primarily  to provide the
service of direct product delivery to the customer.  With very
few exceptions bulk plants and their customers are located in or
near smaller cities and towns, quite removed from dense metropolitan
areas *  The marketing technique of major concern  in this study
involves four steps:  1) gasoline is transported  from the terminal
to the bulk plant in trailers of 8,000 gal, (30,000 Incapacity;
2) the gasoline is transferred from the trailer to storage tanks
at the bulk plant; 3) gasoline is pumped through  a loading rack
into compartmented delivery trucks of 1000 to 3*000 gal. (4,000  to
12,000 1.) total capacity; 4) these smaller trucks then deliver
to the customers'tanks.  Deliveries from small trucks are generally
made to customers who have, 1) tanks with a capacity between  125  and
2,000 gal (500 to 7,600 1.); 2) variable demand and require prompt
delivery and 3) tanks located away from improved roadways or in
other  limited access areas.
  Locations and numbers of bulk plants in the three AQCRs of interest
  are  shown in Figures  2  and  8
                                                                        III-l

-------
 Typical  customers who would  receive  these  smaller volumes of
 gasoline include farms,  "Mom and  Pop"  type service stations, and
 commercial  accounts  such as  vehicle  fleet  operators.
         A  consumer with a high volume  throughput and storage tanks
 large enough  to accommodate  a major  portion of a 8,000 gal  (30,000
 1.)  load of gasoline may buy directly  from the terminal or  he may
 place an order with  a bulk plant.  In  the  Baltimore/Washington, D.C.
 areas, the  majority  of independent jobbers  owned a large transport.
 This allows the bulk plant operator  greater latitude in scheduling
 when, where and how  much gasoline could be  delivered either to the
 bulk plant  or to customers.  For example,  a school bus fleet owner
 with a 4,000  gal (15,000 1.) tank could probably not get a major
 oil company owned transport  to make  about  a 50 mile (80 km.) round
 trip from the terminal to deliver only a portion of the transport
 capacity at a time most convenient to  the  customer.  If this customer
 places an order with the bulk plant, the bulk plant could transport
 a full load of product from  the terminal,  deliver directly to this
 customer and perhaps one or  two others who are nearby to empty the
 transport.  Thus, it is possible for the independent bulk plant opera-
 tor to completely bypass the bulk plant storage and loading facilities.
         In this study a significant amount of gasoline was found to be
 distributed in this manner to account with large tanks, e.g., service
 stations or fleet operators.  The bulk plant operators have been
 aggressively acting  to increase the amount of gasoline sold by direct
 haul from the terminal to the customer.  Direct hauling of gasoline
 is more  profitable because the cost of two transfer operations are
 eliminated.  Also, the operators believe they may be able to comply
with current state requirements to refill  vapor laden  delivery vessels
only at facilities  equipped with a vapor recovery system by bypassing
the bulk plant and  hauling  direct from the major terminal  which is
equipped with  vapor recovery.
                                                                           III-2

-------
      Gasoline bulk plants are diminishing in importance as a
major method of marketing gasoline.   Comparing 1972 Census Data
(8) with the 1975 and 1976 National  Petroleum News marketing
surveys ( 9,10) indicates a closure  of approximately 3,700 bulk
plants nationwide in these four years.  Of the 1810 plants which
closed between 1975 and 1976, almost all were affiliated with major
oil companies.  Commission agent operated bulk plants are frequently
offered for sale to the agent.  If the operator does not elect to
purchase the plant and become an independent jobber, the facility will
generally be completely dismantled.
      Reduced profitability in gasoline sales has been a uni-.
versa! complaint of bulk plant operators.   The most frequently
heard comments were, 1) gasoline allotments have not increased
in the past few years; 2) the purchase price of gasoline at the
terminal has increased; 3) delivery  and operating costs have
increased; 4) gross margins have remained the same; 5) competi-
tion effectively prevents price increases; 6) discount price
self service stations are retailing  gasoline at nearly the same
price  a bulk plant must charge; 7) the cost of complying with
spill  prevention and control  regulations  and vapor recovery  control
requirements has resulted  in  varying degrees of hardship to  the
operators and 8).FEA regulations -- 10 CFR 212.93A and B and 10
CFR 205.D ~ effectively prohibit passing along any non-product
cost,  such  as vapor recovery, to the customer.

B.  BULK PLANTS IN BALTIMORE AND NATIONAL CAPITAL AQCRs
    1.  Description of Bulk Plants Surveyed
       Names and  addresses  of  all bulk plants within the  Baltimore
and National Capital AQCRs are  given  in Appendix A.  Their locations
are shown in  Figure 2, a map  of both AQCRs.
       Both  the Maryland Bureau  of Air Quality  and  Noise  Control
and the Virginia State Air Pollution  Control  Board have  compiled
                                                                            III-3

-------
descriptions of all bulk plants listing, 1) the plant gasoline
throughput; 2) numbers and types of tanks; and 3) numbers and types
of trucks.  The Maryland list, shown in Table II.I-1, is based on 1974
data and also indicates the percentage of gasoline distributed to
exempt customers.   The Virginia list, shown in Table 111-2 is based
on data gathered in 1972, although it was published in a February
1975 emissions data report.  PES has prepared a similar summary,.
presented in Table III-3 of information obtained from personal inter-
views with bulk plant operators in these areas.   Combining and
comparing these three summaries, several statements about through-
put, customers and emissions can be made.
      Two histograms, Figures 3 and  4, have been prepared to show
the average daily gasoline throughput for the bulk plants in the
two AQCRs.  Figure 3 is based on data from Maryland and Virginia
and Figure 4 is based upon PES survey data.   Comparisons among
these data and the previously reported data (1)  are tabulated
below:

-------
      Since the original  of Table III-2  contained  company  names,  a  direct
comparison of changes in  throughput and  storage was possible.   Ten
plants were contacted and all  responded.  As of 1972 the total
throughput at these plants was 15,455,000 gal/year (58,500,000  1/yr)
and their gasoline storage was 393,000 gal. (1,500,000 1.) The  new
data provided PES show their total throughput has decreased by
34% to  10,224,000. gal/year (38,700,000 l/year)although their
gasoline storage capacity has increased by 24,000. gallons. (91?QQQ 1.1
The largest bulk plant operation has decreased its yearly throughput
from  5,400,000 gal (20,000,QQQ 1.1 to 4,500,000 gal,  (17,000,0001,1
Assuming a plant operates five days a week, 52 weeks a year, this
particular facility has decreased its average daily throughput
from 21,000 gal (79,000 l.)to 17,000 gal,  (66,000 1,) One plant which
had a  1972 throughput of 1,600,000 gal  (6,000,000 1).  and a storage
capacity of 34,000 gal (129,000 1.) has closed.  Comments by former
competitors suggested it was  too far from  the majority of its custo-
mers,  so its  transportation costs were  inordinately high.  Even
excluding  this plant, a 25% decrease in gasoline throughput in Virginia
is  still evident,
       In Maryland, the average annual gasoline  throughput appears  to
have  increased.   In  1974,  37  plants  delivered  39,000,000 gal (148,000 1.)
through their loading racks;  28 plants "in  1975 delivered
32,000,000 gal (120,000,000 1.).   Extrapolating the gallonage  through  28
 plants to the expected throughput for 37 plants suggests  an average  increase
 in gasoline volume of 7%.
                                                                           III-5

-------
      Gasoline storage capacity at a typical plant in the Baltimore-
Washington, D.C. area will consist of a 20,000 gal. (76,000 1.)
storage tank for each grade of gasoline—regular, premium and
unleaded.  Excluding one plant with two above ground tanks each
with a 120,000 gal (450,000 1.) capacity, the amount of gasoline
stored in below ground tanks is about 5% greater than that stored
in above ground tanks.  Generally the size range in above ground
tanks is 10,000 to 30,000 gal  (38,000 to 114,000 1.) capacity.  For
underground tanks, the capacities vary from 6,000 to 20,000 gal.
(23,000 to 76,000 1.).  Storage capacity for distillates depends
primarily on the marketing emphasis of a particular plant; therefore,
it may range from 0 upwards.  The largest storage facility could
accommodate 1,900,000 gal. (7,000,000 1.) of fuel oils, kerosene
and diesel fuel.  Overall, the plants surveyed sold about 6 x 10
gal/year (22 x 106 I/year) of distillates.  This is one and one-half
times their total gasoline sales and two and one-half times the
sales of gasoline through the bulk plant.
      Pumping rates are between 100 and 300 gal/min (380 and 1,140
1/min) with the majority having 200 gal/min (760 1/min) pumps.  The
account trucks have capacities of 1,000 to 3,000 gal (3,800 to
11,400 1.) and may have up to five compartments.  The typical  bulk
plant will have two of these trucks for gasoline deliveries.   Plants
with high volumes of distillates may have as many as six other small
trucks, but the operators generally prefer to dedicate a truck for
gasoline.  This reduces problems with contamination and cleaning and
it also reduces the possible number of trucks which might need to be
equipped with vapor recovery equipment.
      Only 10 of the 28 plants surveyed had installed a vapor balance
system on their storage tanks  to return vapors to the transports when
                                                                        III-6

gasoline was received.  (This has often been referred to as Phase
I of a vapor recovery program).  Only one plant has modified the
loading rack and the small delivery trucks to recover vapors
generated during the loading or unloading of gasoline of these
small trucks.  (This would be Phase II of the vapor recovery program).
A detailed discussion of this vapor recovery installation appears
in Section IV.
      Questions asked customers included:

            1.  the amount of gasoline sold to farm accounts
            2.  the size of tanks at farm accounts
            3.  the amount of gasoline sold to customers
                with tanks of less than 2,000 gal. (7,800 1.)
                capaci ty
            4.  the number of new tanks installed since
                January 1, 1973
            5.  what vapor control techniques customers
                have already installed.
      As was stated earlier, Maryland had already asked bulk plants
about their annual sales to farm accounts and to customers with
tanks smaller than 2,000 gal.  (7,800 1.).  The data summary obtained
has been included as Table III-l.  A histogram of the average daily
gasoline throughput to different types of accounts has been pre-
pared from this summary and is shown in Figure 5.  Figure 6 is the
same type histogram prepared from responses made by bulk.pi ants
contacted by PES.
      Based upon the Maryland  data, a daily average of 4,400 gal.
 (16,700 1.) are delivered to farm accounts and 1.18,000 gal.
 (447,000 1.) to small tanks, leaving 73,000 gal,  (276,000 1.) to be
delivered to other accounts, all of which will be treated here as
non-exempt accounts.
                                                                         III-7

-------
      Bulk plant operators stated tanks on farms are all small:
275 gal and 550 gal (1,000 1. and 2,100 1.) were the most common
sizes mentioned."  No one spoke of a farm tank larger than 1,000 gal.
(3,800 1.).  Therefore, in interpreting the two histograms, the left
one third of each graph is incorporated into the middle segment.
One of the first correlations attempted was comparing the through-
put to non-exempt accounts with the total bulk plant throughput.
In Figure 7, the total throughput of each bulk plant in Maryland
is plotted against its throughput to non-exempt accounts,  The
histograms showed a substantial percentage of plants -- 65% in
the Maryland study, 74% in the PES survey --. dispensing less than
1,000 gal/day (3,800 I/day) to non-exempt accounts.   This graph
shows' these plants have a wide range in total gasoline throughput
— up to nearly 12,000 gal/day (44,000 I/day).  The clustering of
points underscores the fact that the traditional marketing emphasis
of a large number of bulk plants has been deliberately focused on
the use and servicing of small tanks.   The larger throughput plants
may also make an effort to deliver gasoline to large accounts directly
from the terminal.
      The 13 plants in Maryland delivering more than 1,000 gal/day
(3,800 I/day) to non-exempt accounts are less easily grouped.  The
average total daily throughput ranges  from 3,500 gal to 10,000 gal.
(13,000 1. to 39,000 1.) and the average daily throughput to non-
exempt accounts ranges from 1,000 to 4,300 gal. (3,800 to 16,000 1.).
      The differences between the graphs in Figures  5 and 6 warrant
some discussion.  There are really three sets of data, obtained
for three different years.  It is very possible that businesses
have changed considerably in only a short time.  The decrease in
throughput for Virginia bulk plants, discussed earlier, could cause
several changes in graphs of gasoline  distribution.   The PES data
do support the speculation put forth earlier that smaller bulk plants
selectively service customers with small tanks.
                                                                        III-8

-------
      The number of new tanks installed since January 1,  1973 is
not known with any degree of certainty.  The majority of  dealers
stated they had not installed any new tanks because of unfavorable
market conditions.  One of the larger distributors stated he had
installed 40 new tanks, all of which were,to the best of  his know-
ledge, in compliance with current Virginia State regulations.  It
also appears that only about nine or ten large accounts with
existing tanks having a capacity of 2,000 gal (7,600 1.)  or more
have  installed submerged fill pipes and vapor return lines on their
tanks.   Four of these accounts were definitely identified as ser-
vice  stations.

    2.   Operational Changes  in Bulk Plants
      Within  the  past year seven bulk  plants  have  been sold  by
two major  oil  companies.   With one exception, the  commission
agent bought  the  plant  he  had  been operating.  Two purchase  prices
disclosed  were $65,000  and $45,000.  The asking  price  for a plant
which was  closed  and  partially dismantled  about  two years ago  is
$60,000, according to a former competitor.
       Extrapolating the data obtained  by PES to  all bulk plants
 in the  Baltimore/Washington, D.C.  area, delivery volumes from
 bulk plants have increased by 7%,  while delivery volumes directly
 from the terminal to the customer, by the bulk plant operator in
 his own transport trailer, have increased by 123%.  Increased sales
 to non-exempt customers account for both increases.  This now means
 nearly  half the gasoline now sold by  bulk plants  is transported
 directly from the terminal to the customer and never passes through
 the  bulk plant.  The implications of  direct haul  deliveries have been
 discussed  in  Part A of this section.  Operators often discussed the
 possibility of transporting even more gasoline directly  to  the cust-
 omers should  they be required to spend substantial  amounts  of money
 for  vapor  control equipment or other  plant modifications which would
 reduce  the profitability  of their operation.  As  stated  earlier,
 direct  delivery  of gasoline from the  terminal to  the customer is less
                                                                         111-9

-------
expensive than transferring gasoline into storage tanks at the bulk
plant and then reloading it into smaller trucks for customer delivery.

    3.  Expected Operational Changes Related to Vapor Recovery
      As stated earlier, only 10 of 28 plants surveyed had installed
a vapor balance system on their storage tanks to return vapors to
the transports when gasoline was received.  Five plants have through-
puts low enough to be exempt from current Maryland and Virginia
State regulations.  However, it is imperative to realize that all
these facilities are subject to Federal regulations.
      In an attempt to assess the economic impact of the investment
in vapor recovery systems by bulk plants, the hypothetical question
was asked, based upon financial and cost data presented in Reference
1, "If a vapor recovery system were to cost you $10,000 ($20,00,
$30,000) initially and 20% of that for annual maintenance, would you
continue to sell gasoline?"  Of the 20 who responded, 5 said they
would stop selling gasoline either altogether or they would not
dispense any through the bulk plant if an initial  expense of $10,000
were required; 6 said they would take the same action if $20,000
were needed; 2 said $30,000 was the limit.  The remainder are people
who just recently bought plants and some very large firms:  they
intend to do whatever is necessary to succeed in their businesses.
      It should be noted that a sufficient market for direct haul
sales exists for bulk plant operators to seriously consider elimina-
ting rack sales of gasoline rather than install vapor control equip-
ment.  A small volume Of customers would most probably have to find
another bulk plant willing to deliver to him should his current
supplier elect to deal  only in direct hauling from the terminal.
                                                                         111-10

C.  BULK PLANTS IN THE HQUSTON/GALVESTON AREA
    1.  Description of Bulk Plants Surveyed
      PES has compiled a list of the bulk plants in nine counties
within the Houston/Galveston AQCR which are affected by vapor
recovery regulations in Appendix A.  The locations of these bulk
plants are shown in Figure 8.
      Since there was no previous bulk plant inventory PES had to
locate all the bulk plants in the area of concern.  A total of
sixty-five to seventy-four bulk plants were operating in the
area.  The range is given because nine operations could not be found
or verified as bulk plants.  Table II1-4 gives a summary of the
data obtained by PES through interviews with thirty-one bulk plant
operators.  The summary includes data on gasoline throughput, type
and capacity of storage tanks, percentage of exempt accounts, type
of vapor recovery installed and number of account trucks,
      The average gasoline throughput at the bulk plants was 8,350
gal/day (31,600 I/day).  A histogram depicting the distribution of
gasoline through the bulk plants surveyed is shown in Figure 9.
Gasoline throughputs were found to range from 2,300 gal/day (8,600
I/day) to 21,600 gal/day  (81,700 I/day).  The total annual through-
put of gasoline for the bulk plants in the Houston/Galveston area
was approximately 152,000,000 gal/year (575,000,000 I/year).
      According to the PES survey  approximately 80% of  the bulk
plants had aboveground tanks.  The average aboveground  storage
capacity was approximately 48,000  gal  (182,000 1.) stored  in three
                                                  t
to four storage tanks.  Aboveground storage tank  sizes  ranged from
1,000 gal  (3,800 1.)  to 42,000 gal  (159,000 1.) with most,tanks  in
the  range of 14,000 to 17,000 gal  (53,000 to 64,000 1.).   The
average storage capcity for  bulk plants with underground tanks was
26,000 gal  (98,000  1.) in  two to three storage tanks.   The size
ranges of underground storage tanks observed was  1,000  gal  (3,800 1.)
                                                                          III-ll

-------
to 18,000 gal  (68,000 1.) and the average tank was 10,000 gal
(38,000 1.).   In only one case did a bulk plant have storage
for gasoline  above and below ground.  One bulk plant operator
planned to change all his aboveground tanks to underground tanks.
He felt that  this would eliminate spillage problems and ease the
installation  of vapor recovery.

      PES found that 75% of the bulk plants in the affected areas
had already installed Phase I vapor recovery for incoming loads
to the plant.   In all cases this consisted of vapor balance systems.
In a majority of these plants, the vapor recovery was installed by
a major oil company since over 70% of all the bulk plants were
associated, either as a consignee or a distributor, with a major
oil company.   This large percentage of vapor recovery installations
was a consequence of the original date for compliance with the
applicable regulations of January 1, 1977.  The date for compliance
has now been delayed to May 31, 1977.  This was announced in
Federal Register, 41_, 56642, December 29, 1976 .
      Pumping rates were much lower than those found in the Mary-
land and Virginia areas.  Pumping rates ranged from 40 gal/min  to
180 gal/min (150 1/min to 680 1/min)  with the majority of plants
having pumping rates less than 100  gal/min (380 1/min).  The
average pumping rate for the plants surveyed was 75 gal/min (285 1/min)
The account trucks owned by the plant operators ranged in size from
1,000 to 4,000 gal (3,800 1. to 15,100 1.).  The average bulk plant
surveyed had  two account trucks.   It was also found that 68% of
the bulk plant operators had installed vapor recovery on at least
one account truck.  The equipment installed generally consisted of
a manifolded  vapor return line, a permanent submerged fill pipe and
overfill  protection.
      The average percentage of exempt accounts — tanks less than
2,000 gal (7,600 1.) and farm accounts -- served by the bulk plants
in the Houston/Galveston area was 67%.  Since these accounts were
                                                                         111-12

-------
smaller than the non-exempt accounts,  only about 50% of the
gasoline throughput was to the exempt accounts.   In some cases
the bulk plant was used to service only exempt accounts with the
non-exempt accounts being serviced directly from the terminal,
bypassing the bulk plant.  For example, one bulk plant operator
had a throughput of gasoline at his plant of 5,000 gal/day
(18,900 I/day) serving only exempt accounts.  This operator then
delivered an additional 27,300 gal/day (103,300 I/day) directly
from the terminal  to non-exempt accounts.  Most of the non-exempt
accounts had installed only recovery  for  incoming  loads, again,
because of  the  required  date  for  compliance with Texas state  gaso-
line vapor  control  regulations,
       Over  90%  of the  bulk plants in  the  area  incorporated top
 loading for account trucks on their  loading racks.   There  was
 one plant  that  had both  top and  bottom loading,  the top loading
 for filling account trucks and the bottom loading  for filling
 large  tanker trucks.   Vapor recovery  controls  were installed on the
 loading racks  in 36% of  the plants.   The  vapor recovery installation
 consisted  of vapor tight connections  similar to those expected in
 bottom loading  vapor recovery installations.   A more detailed
 description of  this vapor recovery installation can be found in
 Section IV.

     2.  Operational Changes in Bulk  Plants
       Twelve bulk plants in the Houston/Galveston area have already
 closed or are closing as of January  1, 1977.  Two operators stated
 they were closing specifically as a  result of the cost of attempting
 to comply with the vapor recovery regulations.  One other plant
 relocated operations to a county which was not affected by vapor
 recovery regulations in order to avoid installing the necessary
 equipment to control hydrocarbon emissions.

    IV.   HYDROCARBON EMISSIONS  CONTROL AT BULK PLANTS

A.  HYDROCARBON EMISSIONS CONTROL REGULATIONS
    1.  Maryland and Virginia Regulations
      Copies of the sections of the State Implementation Plan and
state regulations which apply to bulk plant operations in the
Baltimore and Washington, D.C. areas are given  in Appendix &.
      Included in the Baltimore Intrastate AQCR are the counties
of Harford, Baltimore, Carroll, Howard, and Anne Arundel.  The
National Capital Interstate AQCR includes Prince Georges and
Montgomery counties in Maryland and Alexandria, Fairfax, Loudoun
and Prince William counties in Virginia.
      Federally approved State Implementation Plans for Maryland
and Virginia require gasoline transfer vapor control  in the Balti-
more and National  Capital AQCRs.   In essence all facilities trans-
ferring gasoline from a delivery vessel  into a  stationary storage
container with a capacity greater than 250 gal  (950 1.) are to pre-
vent release to the atmosphere of no less than  90% by weight of
organics in the displaced vapors.   Then the vapor-laden delivery
vessel may be refilled only at facilities with  an equally effective
vapor recovery system.  The regulations do not  apply to 1) stationary
containers having a capacity less than 550 gal  (2,100 1.) used
exclusively for fueling implements of husbandry, 2) any container
having a capacity less than 2,000 gal (7,600 1.) installed prior
to the promulgation of the regulation, 3) transfers made to floating
roof storage tanks (or equivalent).   Nor do they apply to any stationary
container at any facility in the affected areas of Maryland where the
monthly average throughput exceeds 20,000 gal (76,000 1,) and is sub-
ject to Maryland regulations 10.03.38.04J(2)(e) (1) and (2) and
10.03.39.04J(2)(e)(l) and (2).  The date for final  compliance in
both Maryland and in Virginia is May 31, 1977.
                                                                          IV-1

-------
      The aforementioned sections of Maryland State Regulations
require bulk plants having a monthly throughput of 20,000 to
50,000 gal (76,000 to 189,000 1.) to install a vapor balance or
similar system to recover vapors from loading into existing
stationary tanks of capacity less than 40,000 gal (.150,000 1.) by
May 31, 1977,  However, these sections do not discuss the vapor laden
delivery vessel.
      The commonwealth of Virginia "Regulations for the Control and
Abatement of Air Pollution" Section 4.52(e) also differs from the
Virginia SIP.  A critical difference is in the phrase no gasoline shall
be transferred from any delivery vessel into any stationary storage
container with a capacity greater than 2,000 gal (7.600 1.) unless
it is equipped with a submerged fill pipe and a prescribed vapor
recovery system.  Specific exemptions are granted to facilities
whose average monthly gasoline throughput is less than 20,000 gal
(76,000 1.) and all stationary storage containers used predominantly
for refueling mobile farm equipment, as well as transfers to floating
roof tanks (or equivalent).

    2.  Texas Regulations
      The Texas SIP regulations are applicable to the following
counties in the Houston/Galveston area:  Brazoria, Chambers, Fort
Bend, Galveston, Harris, Liberty, Matogorda, Montogomery and Waller.
These regulations require that by May 31, 1977 no gasoline shall be
transferred from a delivery vessel into any stationary container
with a capacity greater than 1,000 gal (3,800 1.) unless it is
equipped with a submerged fill pipe and the vapors displaced from
the storage tank during filling operations are processed by a system
that prevents the release of no less than 90 percent by weight of
the total hydrocarbon compounds.  The vapor laden delivery vessel
can be refilled only at facilities having equally effective vapor
recovery systems.  Exemptions to the Texas SIP regulations include
                                                                         IV-2

-------
those for storage tanks used for the storage of gasoline on a farm
or for farming purposes, for storage tanks having a capacity less
than 2,000 gal (7,600 1.) installed prior to November 3, 1973, and
for storage tanks with floating roofs or equivalent.
      The State of Texas Regulation V, which deals with hydrocarbons,
radically differs from the Texas SIP regulations in that it is appli-
cable only to Brazoria, Galveston, Harris, Matagorda and Montgomery
counties in the Houston/Galveston area.  Regulation V also incorporates
an exemption for bulk plants that have a throughput of less than 20,000
gal (76,000 1.) per day.  This would permit approximately 97% of the
plants in the area to not install vapor recovery equipment,  Copies
of the Texas SIP and State of Texas regulations can be found in
Appendix C.
      These several differences between Federally approved SIP Regu-
lations and separate State Regulations must be resolved before a
successful vapor control strategy can be implemented.


 B.   SOURCES OF EMISSIONS ASSOCIATED WITH  HANDLING OF GASOLINE
       Vapor can  escape from storage tanks,  even  when there is no
 transfer activity, because of changes in  temperature of the tank
 wall  and stored  materials which vary the  pressure in the vapor
 space.   Variation forces vapor-laden air  out  of  the  tank and
 aspirates fresh  air into the vapor space,  allowing further vapori-
 zation of gasoline into that space.   The  amounts of  vapor escaping
 under these conditions are referred to as  "breathing losses."
 Losses of vapors due to liquid transfer are referred to as "working
 losses"  or'""transfer losses."  The liquid  transfer forces air-
 hydrocarbon vapors out during filling of  the  tank and ingests air
 (promoting evaporation) during draining.   Miscellaneous or fugitive
 losses are primarily related to spillage  and  leakage during gasoline
 handling.
                                                                         IV-3

-------
    1-  Breathing Losses
      Factors affecting breathing or standing losses for fixed
roof tanks include the amount and volatility of the gasoline
stored, type and condition of tanks and appendages, and the pre-
vailing meteorological conditions,  If there are no leaks or
direct openings, temperature fluctuation is the major cause of
breathing losses.  As the temperature of the liquid rises, the
vapor pressure increases and evaporation takes place.  The over-
all pressure in the gas space increases and when the vent pressure
set point is exceeded, a mixture of air and hydrocarbons is dis-
charged into the air.  As the temperature decreases, gases partially
condense, contract, and fresh air is drawn into the vapor space.
This permits additional hydrocarbons to vaporize.   Since hydro-
carbons are emitted, but generally not drawn back into the tanks,
a continued loss of hydrocarbon results from the daily changes in
ambient temperature.

    2.  Working Losses
      The principal cause of vapor loss during liquid transfer is
displacement of the gas (air laden with hydrocarbon vapors) in the
vapor space by the liquid entering the tank.  Other causes include
the entrainment of liquid droplets in the displaced gas and post-
withdrawal pressure increase caused by evaporation.
      Certain operating conditions can increase or decrease these
vapor losses.  Splash loading in which gasoline is dumped onto the
surface of the liquid causes turbulence which increases evaporation
rates and entrainment of droplets in the vapor being displaced.
A short interval between emptying and filling of storage tanks
can decrease losses by minimizing the time allowed for evaporation.
Also, storage tanks can be emptied in increments over a period of
several days or can be emptied in one operation prior to refilling,
with resultant differences in vapor loss.
                                                                         IV-4

-------
      Assuming no controls,  each time a gasoline tank is  filled,
the vapors above the liquid  surface are emitted to the atmosphere.
The quantity of hydrocarbon  vapors emitted is  a function  of the
volume displaced, type of loading, temperature and the degree  of
saturation of the vapor space with gasoline vapors.   At any given
temperature, the amount of vapor in the vapor  space cannot exceed
a limit imposed by the saturation pressure corresponding  to that
temperature.  This limit, however, increases as the temperature
increases.
      In a quiescent state,  the approach to saturation and pressure
increase of a vapor space with gasoline vapors is a slow  process.
Since hydrocarbon vapors are heavier than air  and diffusion is
slow, a saturated blanket of vapor initially forms over the liquid
surface, decreasing the driving force for further vaporization.   Also,
with evaporation of the lighter hydrocarbon molecules, the tendency
of the components in the stagnant surface to vaporize decreases.
Thus, the degree of saturation in the overall  gas space of a tank
can be decreased by minimizing liquid surface  and vapor space  mixing
during the filling operation.
      Splash loading not only creates liquid droplets which can  be
entrained in the outgoing effluent and exposes fresh liquid surfaces,
but results in mixing of the vapor space as well.  This mixing of the
vapors disturbs the saturated blanket near the liquid surface,
increasing the driving force for further vaporization. Hydrocarbon
emissions under splash filling conditions can  significantly exceed
that calculated by assuming saturation C6).
      Another factor which can affect the quantity of hydrocarbons
emitted is the interval between drainage and filling.  When a tank
is drained and immediately refilled, the air drawn into the tank
during draining may be expelled with relatively little hydrocarbon
content.  In a tank allowed to sit after draining, the air drawn
                                                                         IV-5

-------
into the vapor space becomes saturated with hydrocarbons, thus,
increasing pressure Cand emissions) and resulting in the maximum
loss of vapor during refilling.
      Another operational procedure which may increase losses is
the small sequential withdrawals of gasoline from a storage tank
over a period of several days rather than one continuous large
withdrawal.  After a small withdrawal, the post-transfer emissions
caused by evaporation tend to be high in hydrocarbons since little
air is ingested during the withdrawal.  After a large withdrawal,
the initial post transfer emissions are low in hydrocarbons since
large amounts of air are ingested during the withdrawal.

    3.   Miscellaneous Losses
      Miscellaneous losses have been found to be highly variable.
These losses include spillage, liquid and vapor leakage and opera-
tional  losses which occur when opening tank hatches for visual
inspection or measuring liquid levels with dip sticks.   Leakage
can occur and has been observed at dry breaks, pressure vacuum
valves, hatches,  manholes, pump seals, shut-off valves  and piping
joints.  It has been visually observed that some spillage (on the
order of half liter) occurs when connecting and disconnecting
transfer lines.   Visible liquid leakage at dry breaks (few milli-
liters  of gasoline) was observed from the connections after trans-
fer.   Opening of  hatches generally does not occur during transfer,
although several  operators report they will open the hatches of
an empty truck to verify that they have received all the gasoline
expected,
                                                                        IV-6

-------
C.  EMISSION CONTROL TECHNOLOGY
    1.  Breathing Losses
      Storage tanks are subject to evaporation or standing  losses  due
to volatility of the material  stored,  type and condition  of the  tank
and its appendages and prevailing meteorological  conditions.   The
simplest methods for reducing  these venting losses are  to (1)  inspect
and repair leaks in the tank and fittings, (2) paint the  tank  with
white paint where possible, (3) assure that vent  valves do  not leak
and (4) set the pressure and vacuum relief settings to  minimize
breathing.  The broader the band for the vent valve settings,  the
lower will be the breathing losses.
      Another method for preventing vapor loss is to install  vapor
recovery equipment at the vent valve.   For vapor  recovery,  the vented
vapor must be able to be condensed and recycled to the  tank or be
collected and regenerated.   For prevention of pollution only,  the
vapors can be combusted or collected and disposed of in some approved
manner.
      Regulations do not generally require specific control of breathing
losses.  No further consideration will therefore  be given to these con-
trol methods.

    2.  Working Losses
      Excluding spillage, the two major sources of loss of gasoline
vapor during transfer are 1) venting to the atmosphere  the volume  of
gases—air and hydrocarbons—displaced by the entering  liquid and
2) filling in a manner which creates turbulence which results in in-
creased vaporization rates and liquid droplet entrainment in the
vapor space.
      The most common current methods of reducing working losses are
to use submerged filling for the loading of gasoline and  to install  a
vapor balance system between the vapor spaces of  the tanks connected
during the gasoline transfer.
                                                                         IV-7

-------
    a-  Submerged Fill
      Submerged fill is the introduction of liquid gasoline into
the tank being filled with the transfer line outlet being below
the liquid surface.  This is compared to splash loading, where
the transfer line outlet is at the top of the tank.  Submerged
filling minimizes droplet entrainment, added vaporization and
turbulence.  If a fill port is located at the tank top, submerged
fill is accomplished by either extending the nozzle (commonly
referred to as stingers) or permanently attaching to the fill
port a pipe extending to within 6 inches (.15 cm) of the tank
bottom.  This permanent installation is commonly referred to as
a drop tube.
      Aboveground storage tanks normally include submerged fill.
Submerged fill for underground storage tanks can be accomplished
by attaching a pipe to the fill port.  These installations are
common on underground tanks in surveyed areas.
      Bottom loaded trucks by definition include submerged
filling.  Top loaded trucks utilize an extension such as a pipe
or flexible hose facility loading arm.  The extension may be
permanently attached if the loading arm can be raised sufficiently
to clear the trucks.  No development is necessary except for
customer tanks.   The major problem encountered, spitback from cus-
tomer tanks, can be overcome by inserting a long tube-like nozzle
(a stinger) through the filling pipe.
      Submerged filling can reduce working losses to a significant
degree and is easily adapted to an underground storage tank, or top-
loading truck.  As mentioned earlier, submerged fill is an integral
feature with bottom-loading trucks and aboveground tanks.  The
system has no significant effect on breathing losses.   Cost of
                                                                        IV-8

-------
conversion is extremely low and applicability to bulk plant opera-
tions is good.  In top-loading facilities a nozzle extension is
the only addition necessary to provide for subsurface loading of
the account trucks.  For underground storage tanks, a pipe is
normally affixed inside so that the discharge occurs near the
bottom.
      Submerged filling of customer tanks can be accomplished with
either nozzle extension or a permanently attached drop tube.  Some
difficulties have occurred with the installation and use of per-
manent drop tubes.  One problem is "spit back."  "Spit back" is
the return flow and spillage of gasoline at the fill  port during
transfer.   This appears to be primarily related to the smaller fill
port and drop tube sizes in customer tanks, compared to service
station tanks, and the lack of a coupling at the fill port inter-
face.  Use of a nozzle extension with or without a permanently
installed drop tube or a coupling should solve the "spit back"
problem.
      Another difficulty with the use of submerged filling with
customer tanks is the variety of fill ports.  Fill ports vary in
diameter, type and accessibility.  The problem can be likened to
the variety of vehicle fuel tank interfaces.  The total costs to
adapt to this number and variety of customer tank interfaces may
be significant.  In addition, operators indicate submerged fill
hardware is not available for some configurations.
      One question which arises is the actual usage of submerged
fill when the system is installed.  For instance, if a top loading
rack or "drop tube" cannot be permanently attached, due to inade-
quate truck clearance, the driver has a little incentive to attach
the drop tube prior to each filling of the account truck.
Similarity a driver may not bother using a variety of detachable
"stingers" during the customer tank filling.
                                                                        IV-9

-------
    b.  Balance System
      Probably the most common vapor recovery system currently in
use is the vapor balance system.  Efficiency is good for the
control of working losses, but not significant fn controlling
breathing losses.  A pipeline between the vapor spaces of the
truck and storage tanks essentially creates a closed system per-
mitting the vapor spaces of the tank being filled and the tank
being emptied to balance with each other.  The net effect of the
system is to transfer vapor displaced by liquid into the tank in
which draining of the liquid creates additional vapor space.
This prevents the compression and expansion of vapor spaces which
would otherwise occur in a filling operation.  If a system is
leak tight, very little or no air is drawn into the system and
venting due to compression also is reduced substantially.  The
system is applicable to underground and aboveground storage
facilities equipped with either bottom or top loading.
      Typical facility modifications involved adding aboveground
piping from the incoming truck unloading area to a manifold inter-
connected with all gasoline storage tanks.  The vapor return pip-
ing is generally  2  to  3  inches  (5  to  8  cm) in nominal  diameter
and it is sloped on horizontal runs to drain any condensate.
The no-lead tank may have special protection against contamination
from leaded gasoline vapors.   Non-metallic piping may be used if
local codes allow.
                                                                       IV-10

-------
      The vapor return line entry into the storage tank may require
(1) attachment of a metal  plate which can be drilled and tapped or
welded onto, (2) drilling and tapping or welding onto an existing
appendage, (3) using an existing port, or (4) teeing off an
existing vent line piping.  The older the tank, the less likely
an existing port or vent line will be available for use.  Older
riveted tank material may not be easily weldable,
      The most common problem noted was leakage.  Old tank hatches,
valves, seals, manholes and sealing surfaces may require significant
repair or replacement to affect a seal.  In addition, even if only
a replacement component is required, the lack of spare parts for
discontinued models may require special orders further increasing
costs.  If costs to an individual bulk plant owner begin approaching
the high end of the range of costs for this modification ($10,000),
the owner may investigate replacement and possible relocation of
storage tanks underground.
     Instaflation of a balance system to the loading rack to return
vapors from the account truck to the storage tank has been compli-
cated in many instances by including a conversion of the loading
rack from top loading to bottom loading.  There is no requirement
in the Federal vapor recovery regulations to include this particular
modification.
     Top loading vapor recovery installations observed in the Houston/
Galveston area warrant special attention because of their simplicity,
apparent effectiveness and corresponding low cost:  Because these
installations require minimal conversion of the top loading rack, the
total cost for the Phase I and Phase II vapor recovery installation
and the conversion of one account truck for submerged fill and vapor
recovery would cost approximately $10,000.  This amount is considerably
less than costs quoted for bottom loading systems.
                                                                        IV-11

-------
     The Phase I vapor recovery system consisted of installing
vapor return piping to each storage tank handling gasoline and
a vapor return dry break coupler to prevent vapors escaping from
the system when the return line was not connected.
     The Phase II vapor recovery piping to the loading rack branches
off the Phase I vapor return line and runs to the loading rack,
The piping to the loading rack is usually placed underground to
minimize problems with truck traffic.  At the loading rack, a
flexible hose is attached to the vapor return line and then a dry
break or vapor tight fitting is affixed to the hose.  Again, this
is to eliminate vapor losses to the atmosphere when the return
line is not connected.
     The top loading rack is then modified to enable the vapor
tight delivery of gasoline to the account truck.  The existing
fittings on the loading arm are removed and a vapor tight connector,
                          (0)
similar to the OPW Kamlockv ' fitting is attached,  If the loading
arm is unable to move in both horizontal and vertical planes for
exact alignment with the compatible coupler on the account truck a
flexible hose is used for this purpose.  One end of the hose is
attached to the loading arm and the coupler is attached to the other
end, thereby providing a flexible connection similar to that on the vapor
return hose.
     The conversion of the account truck is the last segment of
the vapor recovery system installation.  The modifications required
are performed on each compartment of the account truck.  The vapor
return line installation involves welding a pipe into each compart-
ment and then joining all  pipes together in a manifold (See Figure
10).  This manifold line leads to a compatible fitting for the
flexible vapor return line at the loading rack,  A hole is drilled
into each compartment and a submerged fill  pipe is permanently
attached.  To the top of this submerged fill pipe is attached the
compatible vapor tight connector for the top loading arm.   A cap is
                                                                        IV-12

leakage of vapors to the entrance of dirt or other impurities.
The last item to be installed in a compartment is the overfill
protection.  At the plants visited a graduated rod with a float
at the base designed to rise with the level of the gasoline was
being used.  Graduations of the rod could then be calibrated to
indicate the amount of gasoline in the compartment.  This type of
overfill protection was critized by many of the bulk plant opera-
tors interviewed.  They stated that the rod would often stick and give
inaccurate results.  Many of them therefore had little confidence in
this type overfill protection system.  Other than this complaint,
the bulk plant operators interviewed did not state any operational
problems.
      If a conversion of the loading rack from top loading and bottom
loading is included in the total modification, it should be empha-
sized that the work is being done to modernize the facility and
speed up and simplify loading procedures, not because it is neces-
sary in order to provide a sufficiently effective vapor recovery
system.  In Maryland and Virginia, only one plant has become involved
with this phase of vapor recovery.  This particular facility elected
to convert to bottom loading mainly because they considered the
installation costs to be competitive and the system to be simpler
and safer to operate.  The conversion, performed in 1974, required
complete dismantling of the loading rack and installation of meters,
valves, hoses, couplers, and accessory equipment for three product
lines.

D.  EMISSIONS ESTIMATES
    1.  Baltimore and Washington, D.C.  Areas
     Both Maryland and Virginia have prepared estimates of hydro-
carbon emissions in the AQCRs of concern (3, 4, 5).   Because the
years upon which these emissions inventories were based differ,
and the calculation techniques also differed, current gasoline
distribution throughout the two AQCRs will  only be an estimate.
Comparisons will be based on extrapolating  1971 and 1972 data to
1975 using the total gasoline consumption in Maryland for 1971
                            g
and  1975:   in 1971  1.3 x 10  gallons of gasoline were  consumed  in
the  eight  Maryland  counties of  interest; in  1975 1.5 x  109 gallons
were  consumed?   The difference  between these two numbers will  be
used  as  the overall  growth  rate, that is, 4.4% per year.
      The table  below summarizes  the  initial  data provided on  gaso-
line  distribution.

 indiscriminately will  introduce some error:  for example, it has
 been stated earlier that bulk plant throughputs in Virginia have
 declined  substantially.  Still, the comparison is useful.  Table IV-1

      Emissions from gasoline storage and handling were reported by
counties for 1971 (4).   They are summarized here for each AQCR.

      National Capitol AQCR
15,300 tons/year
(13,900 metric tons/year)
15,000 tons/year
(13,600 metric tons/year)
      The Maryland 1975 Emissions Inventory (5) indicates hydrocar-
bons emitted from gasoline storage and handling have decreased in
the Baltimore area to 11,200 ton/year (10,200 metric tons/year) and
in Montgomery and Prince George's counties from 5,200 tons/year
(4,700 metric tons/year) to 4,100 tons/year (3,700 metric tons/year.)
Using the changes in Baltimore area counties as typical  of the
entire Washington, D.C. area the emissions there for 1975 are esti-
mated at 11,000 ton/year (10,000 metric tons/year).
      The Virginia emissions report (3) estimated the specific con-
tribution of bulk plants to hydrocarbon emissions from gasoline
storage and handling.  In 1972, bulk plants were calculated to contri-
bute 207 tons/year (188 metric tons/year).  The Council  of Govern-
ments in Washington, D.C. prepared their own inventory for 1973 in
which the Virginia bulk plants were considered responsible for 69%
of the emissions from all bulk plants in the AQCR,  Thus, in 1972,
                                                                         IV-16

-------
bulk plants in the National  Capitol  AQCR emitted 299 tons  of  hydro-
carbons (271  metric tons).
      Because the PES survey of Virginia plants  found their through-
put had decreased since 1972, their  emissions  will  also have  decreased.
For the purpose of comparing 1972 Virginia data  with 1974  Maryland
data, PES is  going to assume that 1974 Virginia  bulk plant throughputs
remained at the levels tabulated for 1972,
      As a result of recent revisions to emission factors  for gasoline
marketing operations in "Compilation of Air Pollutant Emission Factors"
and a proportioning of these factors for use with bulk plant  operations  (2)_,
the 1972 emissions recalculated.   Then estimates of current emissions and
future emissions, assuming  various control strategies, can be made and
compared with past situations.
      The following emissions factors were applied:

      Fixed roof storage tanks; breathing loss
                                working loss

      Emissions from  bulk plants in the several Maryland counties of

      In order to estimate what portion of these bulk plant
emissions occur around Baltimore, PES intends to assume that the
number of plants near Baltimore is directly related to their con-
tribution of hydrocarbons.  Thus 34/43 of the 515 tons/year or 407 tons/
year  (369 metric tons/year) are emitted by bulk plants in the Baltimore AQCR.
Likewise, 9/43 of the 515 tons/year plus 295 tons/year from Virginia
bulk  plants or 403 tons/year (366 metric tonsVyear) are emitted by bulk
plants in the National Capital AQCR.
      The results of this plant survey also provide sufficient
data  to estimate current emissions.  The one assumption which must
be used is that the sample is a representative proportion of the
whole.  Data needed for calculating emissions are summarized below:

      Emissions from these 28 bulk plants surveyed can be categorized as
follows:

      Applying a ratio of the number of operating plants  to the
number of plants surveyed,present emissions can be estimated as
follows:

                              Virginia            Maryland

      Proportioning the Maryland emissions between the Baltimore
and Washington, D.C.  areas directly in accordance with the number
of plants -- 34 near Baltimore, 9 near Washington, D.C.  — current
bulk plant emissions are estimated to be:
     •Baltimore AQCR         428 tons/year (388 metric tons/yr)
      National Capital  AQCR  297 tons/year (270 metric tons/yr)
The decrease in throughputs in Virginia bulk plants from the time
of the Virginia state survey to the time of the PES survey is
responsible for the difference between the two emission estimates
      These emission estimates do not include area wide emissions
produced by filling of the customer's tanks.  This survey

At this time there is not sufficient data to estimate the breathing
losses of customer tanks.  Also, there is no current requirements to
attempt to control this emission source.
      The estimates of 428 tons hydrocarbons year from bulk plants
and 276 tons/year from filling consumers' tanks in the Baltimore
area and 297 tons hydrocarbon/year from bulk plants and 110 tons/year
from filling consumers' tanks in the Washington, D.C. area will be
used in further estimates of how much reduction in emissions is
possible with various control strategies.
      Current Maryland and Virginia state regulations* exempt bulk plants
having an average monthly throughput of less than 20,000 gal (76,000
K-)   from all vapor control requirements.  A total of four plants
with a combined monthly throughput of 63,000 gal (2, 400, 000 1.)  would
be involved.  Thus, if these regulations were enforced emissions
would decrease to the following amounts:
*See appendix B

As a result of using vapor balance systems to recover 90% of the
hydrocarbons emitted miscellaneous losses would also decrease, but
at this point no means of preparing a reasonable estimate appears
to be available.  Thus, by allowing the states to retain present
requirements, emissions would be reduced in the Baltimore AQCR by
at least 258 tons/year (234 metric tons/year) and in the National
Capital AQCR, by at least 165 tons/year (150 metric tons/year).
      Enforcement of the Federally approved SIP regulations would
result in the four previously mentioned plants also having to install
vapor recovery systems on their facilities.  Emissions from gasoline
handling would be reduced by 2.5 tons/yr (2.3 kkg/yr) in the Baltimore
area and by 1.8 tons/year (1.6 kkg/yr) in the Washington D.C. area.
      As more plants install the appropriate vapor recovery control
systems, the reduction in hydrocarbon emissions will, of course, be
more noticeable.  Table IV-2 provides a comparison of how the various
size bulk plants affect hydrocarbon emissions in the two AQCRs.  In
calculating these estimates plants with vapor recovery already in-
stalled have been assumed to keep the system operating at a 90%
efficiency level and all  exempt plants have at least submerged
filling of their trucks.

    2.  jjQMtpn/Galveston, Texas Area
      Emission estimates for the bulk plants in the Houston/
Galveston area have been calculated for uncontrolled sources, for
emissions from bulk plants with current vapor recovery controls,
and emissions from bulk plants with potential control under the
existing Texas SIP regulations.  For estimating uncontrolled
emissions, it was assumed that no vapor recovery equipment was
installed and that all tank fillings and transfers to account
trucks were by splash filling.  This would amount to the worst
case emissions.   For the purposes of these calculations, the
average annual throughput of gasoline through each bulk plant
was 2,203,000 gal (8,338,000 1.], based upon the PES bulk plant
sample.  Also for the purposes of these calculations, seventy
bulk plants were assumed to be operating in the area.  This
number was arrived at by including five of the nine unvarified
plants and deleting four operations which PES believes are not
operating bulk plants.
      The uncontrolled emissions from the bulk plants in the
Houston/Galveston area are:

      Breathing losses from aboveground tanks -
            236 tons/year (214 metric tons/year)
      Working losses from all bulk plant storage tanks -
            737 tons/year (668 metric tons/year)
      Transfer losses from filling account trucks -
           1063 tons/year (964 metric tons/year)
      Transfer losses from filling account's storage tanks -
           1063 tons/year (964 metric tons/year)
      Miscellaneous losses -
            243 tons/year (220 metric tons/year)
      Total uncontrolled hydrocarbon emissions -
           3342 tons/year (3031 metric tons/year)
                                                                        IV-24

-------
The emission factors used for these emission estimates are the
same as those listed in the previous section on Baltimore and
National Capital regions.
      The total projected hydrocarbon emissions for the Houston/
Galveston area (11) for 1977, base year 1971, are 314,853 tons/
year (285,572 metric tons/year).  The projected hydrocarbon
emissions from gasoline marketing sources are 20,803 tons/year
(18,868 metric tons/year).  This indicates that 6.6% of the total
hydrocarbon emissions originate from gasoline marketing sources
and based upon PES estimates, 16.1% of the gasoline marketing
emissions originate from bulk plants.
      The total amount of gasoline consumed in the nine affected
counties amounted to approximately 2.8 billion gallons (10.6
billion liters) in 1976.  This information was derived from fuel
tax records and information on vehicle population in the nine
counties (12).  The total  amount of gasoline which passed through
the bulk plants was approximately 154 million gallons (583'million
liters) or about 5.5% of the total gasoline consumed,
      To determine current emissions from bulk plants, data on
Phase I and Phase II controls installed were obtained from the
PES bulk plant survey.  From this data, it was found that 75%
of all the bulk plants had installed Phase I vapor recovery.
Phase II controls were installed at 36% of all the bulk plants.
Vapor recovery had been installed on at least one truck at 68%
of the facilities.  For calculation purposes, it was assumed,
since most bulk plants had one truck with vapor recovery and one
without, that the deliveries which went to exempt accounts, i.e.,
farm accounts and tanks less than 2,000 gal  (7.6QQ 1,), were made
with the delivery truck which had no vapor recovery.  From the
PES survey, the average bulk plant delivered 50% of its gasoline
— 67% of its accounts -- to exempt accounts.  An efficiency of
90% for the Phase I and Phase II controls was used.
                                                                       IV-25

-------
      The hydrocarbon emission estimates for the bulk plants
in the Houston/Galveston area incorporating current vapor recovery
control installations are:

      Breathing losses from aboveground tanks -
            236 tons/year (214 metric tons/year)
      Working losses from all bulk plant storage tanks -
            239 tons/year C217 metric tons/year)
      Transfer losses from filling account trucks -
            791 tons/year (718 metric tons/year)
      Transfer losses from filling account's storage tanks -
            638 tons/year (579 metric tons/year)
      Miscellaneous losses -
            243 tons/year (220 metric tons/year)
      Total hydrocarbon emissions incorporating current control
      practices -
           2148 tons/year (1948 metric tons/year)
Under current control practices, a 67.5% reduction in working losses,
a 25.6% reduction in transfer losses involving account trucks and a
40% reduction in transfer losses involving account tanks served  have
been accomplished.  This is an overall hydrocarbon emission reduction
of 35.7% representing 1,194 tons/year (1,083 metric tons/year) from
all bulk plant emission sources.
      To determine the amount of potential reduction of the hydro-
carbon emissions, the vapor recovery and emission controls as
outlined in the Texas SIP regulations were extrapolated for the
gasoline throughput used above.   This would mean that Phase I con-
trols would be installed on all  bulk plants, Phase II controls on
the racks would be used on all non-exempt deliveries and submerged
fill pipes would be installed on all non-exempt tanks.  The SIP
regulations, as written, do not require any controls to limit
storage tank breating losses and miscellaneous losses (i.e.,
spillage) so these emissions levels do not vary.
                                                                        IV-26

-------
      The hydrocarbon emission estimates for the bulk plants in
the Houston/Galveston area incorporating potential vapor recovery
controls are:

      Breathing losses from aboveground tanks -
            236 tons/year (214 metric tons/year)
      Working losses from all bulk plant storage tanks -
             74 tons/year (67 metric tons/year)
      Transfer losses from filling account trucks -
            585 tons/year (530 metric tons/year)
      Transfer losses from filling account's storage tanks -
            585 tons/year (530 metric tons/year)
      Miscellaneous losses -
            243 tons/year (220 metric tons/year)
      Total hydrocarbon emissions incorporating potential
      emission controls under Texas SIP regulations -
           1723 tons/year (1562 metric tons/year)
Under potential control strategies presented in the Texas  SIP
regulations, a 90% reduction in hydrocarbon working losses from
bulk plant storage tanks and a 45% reduction of transfer losses
to both account trucks and account tankage could be experienced.
This would yield an overall  bulk plant emissions reduction of
48.5% or 1620 tons/year (1469 metric tons/year).  If it is assumed
that all deliveries made from the bulk plant would require Phase
II controls, not just non-exempt deliveries, a further reduction
in bulk plant emissions would occur.  The overall bulk plant hydro-
carbon emissions would then be reduced to 1244 tons/year (1128
metric tons/year).  This would then indicate an overall emissions
reduction of 63% or 2098 tons/year (1903 metric tons/year).
      The effects of various selected increments of compliance with
vapor recovery regulations on the hydrocarbon emissions from bulk
plants in the Houston/Galveston area are summarized in Table IV-3.   The
current Texas SIP regulations have exemptions relating to  deliveries
to farm accounts and tanks of less than 2,000 gal.  capacity (7,600 1.)
                                                                         IV-27

Over  70% of the bulk plants have already installed Phase I vapor
control systems and over 30% have installed Phase II control systems
in order to comply with these regulations.

E.  DIRECT COSTS OF EMISSION CONTROL SYSTEMS
      Initial costs of hydrocarbon control systems are reviewed in
the sequential order in which gasoline is received and then trans-
ferred from bulk plants:  incoming transfer, storage, outgoing
transfer and operating and maintenance costs,

    1.  Modification of Incoming Transports
      Because a gasoline transport may be owned by a major oil
company or a common carrier or it could be used to deliver other
highly volatile organic materials the cost of installing gasoline
vapor recovery equipment on a transport can not be considered a
necessary portion of a bulk plants direct expense,
      Cost estimates for installing vapor recovery and bottom
loading on a supply transport have been obtained for general
information.  They range from $1000 to $1800 per compartment, with
the total cost depending on the truck configuration.  The most
common truck design has three or four compartments,  and the average
conversion price per compartment is $1200, so the total cost is
$3600 to $4800.   The most expensive conversion cost quoted by any
operator was $8000.
      Trucks originally designed for top loading are generally being
modified to provide for bottom loading and vapor recovery at the
same time.   Bottom loading of transports is frequently cited as
necessary in order to be compatible with loading facilities at the
particular terminal supplying the bulk plant.   However, a terminal
may also supply bulk plants located outside the affected AQCRs, so
that some terminals have maintained top loading facilities with vapor
recovery capability.
                                                                        IV-29

    2.  Submerged Fill Installation
      A common requirement for filling storage tanks is that the
discharge opening be within 6 in (.15 cm] of the tank bottom.
Underground tanks therefore need to be equipped with a submerged
fill pipe or drop tube such as OPW 61-T.  The cost of this hard-
ware is minimal and installation is quite simple.

    3.  Balance System Installation Costs
      The balance system is the most common method of controlling
emissions from filling and emptying storage tanks.  The table below
summarizes the initial cost data obtained for installations in
Baltimore/Washington, D.C. and Houston/Galveston.

Initial cost includes hardware and installation.  Typical hardware
for aboveground tanks includes piping, fittings, supports, pressure-
vacuum (PV)  valves, liquid traps, paint, disconnects, seals and
gaskets.  Typical installation work includes draining the tank,
assembling piping and supports, breaking into existing tank top
or vent, painting,  leak testing, replacing PV valve, replacing
seals and occasionally repairing leaks by welding tanks or covers.
Miscellaneous costs include permit fees, inspection, insurance,

temporary barricades and cleanup.  Costs listed do not include
facility down-time, contract negotiation time, design and drafting,
and time to obtain financing.
      If underground tanks require only a coaxial fitting such as
Emco Wheaton F-298, a typical installed cost is $600.  A small
diameter fill port, side fill, PV vent requirements, leaks,
concrete work and overfill protection can raise the cost signi-
ficantly.  However, the cost of installing a balance system on an
underground tank is generally lower than the installation on an
aboveground tank.
      In about 30% of the cases studied, the operators performed
the installations.  Although some direct labor costs were included
in the estimate, costs generally represent only hardware costs.
These installation costs will not be included in the average cost
of a control system for incoming loads because of:  (1)  general
lack of associated labor costs, (2) discrimination against those
not able to install by themselves.
      If a typical bulk plant with aboveground storage tanks is
used as a base, the average and range of costs derived from major
oil companies, contractors and operators is fairly consistent with
the average cost being about $3000.  The overall range was $600
to $7000.
      Very detailed data on Phase I vapor recovery costs were
obtained from a representative of an independent oil company which
presently operates seven bulk plants within the Baltimore and
National Capital AQCRs.   Equipping their transports with vapor
recovery has averaged $3500/truck.   Installing a balance system
to comply with Phase I has cost between $1300 and $7000.  The
highest cost resulted from having to run piping an unusually long
distance to connect all  storage tanks.
                                                                        IV-3T

-------
      The technique this company is using to equip storage tanks
with vapor recovery devices is quite interesting.   All  modifica-
tions are being installed in the manhole covers of aboveground
tanks.  Essentially a ball  vent valve (Universal  Valve  Co. #37,
with a three inch float) a  combination vent gauge hatch (McDonald
925-U) are installed in the manhole cover, then a tight seal
coupler is attached to the  ball vent valve line.   This  then pro-
vides a means of manifolding together however many tanks are
needed.

    4.  Outgoing Gasoline Transfer Control Costs
      Data from both this study and previous work (1) indicate a
significant difference in the cost of Installing a top  loading
vapor recovery system compared with a bottom loading vapor recovery
system.  The industry has generally emphasized the conversion of
top loading racks to bottom loading racks.  This has resulted in
the reporting of costs which are biased toward the more expensive
system.
      In conducting this study, over a third of the facilities
visited in the Houston/Galveston area were found to have installed
a top loading vapor balance system on their loading racks and
smaller delivery trucks.  (The details of this system have been
given in Section III),  Four major oil companies who have used this
approach provided reasonably detailed cost data:   1) modifying
the loading rack—necessary piping, fittings and hoses—will  cost
approximately $3000 to $5000; 2) adapting the account trucks-
submerged fill tubes, fittings and overfill protection—will  cost
between $2000 and $4000.  Therefore, for the installation of
Phase I and Phase II vapor recovery at the bulk plant and the modi-
fication of one account truck, the total cost to the bulk plant
would be between $8000 and $12000.
      Only one East Coast firm interviewed had obtained a bid
(of $13000) for a top loading Phase II vapor recovery installations.
                                                                        IV-32

-------
Because top loading vapor recovery appears to be a less expensive
means of controlling hydrocarbon vapors from bulk plant outgoing
transfer operations and because cost data are sparse, an in-depth
study of installation costs, system design and efficiency appears
warranted.
      With regard to bottom loading vapor recovery systems,  only
one plant in the Baltimore AQCR had installed this equipment.
In 1974 this plant totally replaced its loading rack.  The equip-
ment cost then was $12000 and the labor cost was $9000.  Allowing
for an annual cost increase of 10%, this same installation would
probably now cost about $28000.   The only other bulk plant in  the
Baltimore area which had considered a similar installation had
received a bid of $24000,  The difficulty in interpreting this
quote, and most others for bottom loading system, is establishing
how much was spent in modernizing the facility and how much  was
spent in order to comply with vapor control  regulations.

       Very  little  more was  learned  about  the possibility of con-
 verting from top  loading to bottom  loading.   If  the  conversion
 can  be accomplished by  removing  the loading  arms  at  the  level of
 the  rack and replacing  them with flexible connecting hoses, the
 cost would  be between $8,000 and $14,000, depending  upon  the
 need for new meters,  electrical  controls, etc,   A completely
 new  loading rack for three  grades of gasoline  was estimated at
 $19,000.
                                                                        IV-33

-------
     5.  Modification of Account Trucks
      As mentioned above, oil companies in Texas who have used
an approach of installing vapor tight connections on top loading
account trucks have spent $2,000 to $4,000 per truck.
      Those few operators who planned to continue top loading
with such vapor recovery systems as OPW V-63-F estimated instal-
ling vapor recovery on their account trucks would average $2,500
per truck.
      Operators who converted their small trucks to bottom loading
and installed vapor recovery spent from $3,000 to $6,000, depending
upon the existing design of the truck.

    6.  Cost of Vapor Recovery Equipment on Customer Tanks
      The first problem encountered is that of who is responsible
for any modifications which may be needed -- the supplier or the user.
At this time, it seems to depend totally on the individual  opera--
tor's business judgment.   The costs are generally $200 to $600 per
tank, so for a bulk plant servicing say 50 non-exempt tanks, the
total cost would be quite substantial.  On the other hand,  a user
would probably not have more than three non-exempt tanks, which
would involve a maximum expenditure of about $2,000.

    7.  Operating and Maintenance Costs
      Only a few bulk plant operators have had long-term experience
with vapor recovery systems,  Thus, cost information is  limited.
Maintenance costs for vapor balance and bottom-loading are  generally
expected to be small.   Transfer hoses and mating fittings will
require replacement.   Installation of automatic controls for loading
and unloading of gasoline may impose additional  maintenance require-
ments.  No direct information on operating costs was available,
      Based upon experience with balance systems in  service stations,
one major oil  company estimated the annual  costs of  a balance system
in a bulk plant to be apportioned as follows:
                                                                       IV-34

-------
                                 Percent of initial system cost
  Interest (8 years at 10%)                  6,2
  Depreciation                              12.5
  Property taxes                             2.5
  Maintenance                                3.0
                                            24.2
Thus, if a bulk plant installs a vapor recovery system for an
initial cost of $10,000   the operator may expect to spend nearly
$2,500 a year to operate and properly maintain the equipment.
      Any increase in facility value should increase assessments,
thereby increasing taxes.   The amount will  vary with tax rates
and assessments.
      Possible increases in insurance rates due to vapor balancing
have not been resolved.   To date, insurance companies have not
indicated a change in rate due to any change in risk category.

      Although information on these miscellaneous costs is limited,
it appears that; (1) operating of maintenance costs for vapor
recovery may be significant and (2) the primary impact is directly
related to the initial cost.
                                                                       IV-35

          V.   PROJECT APPROACH  AND  METHODOLOGY

A.   INFORMATION SOUGHT ABOUT BULK PLANTS
     1.  Inventory of Bulk Plants
      An inventory of petroleum bulk plants for the National
Capital, Baltimore and Houston/Galveston AQCRs was prepared from
information obtained by contacting the several governmental regu-
latory agencies concerned and has been presented in Section III.
The  agencies contacted include Region III and Region VI office of
the  EPA, Maryland State Department of Health and Mental Hygiene,
District of Columbia Department of Environmental Services,  Virginia
State Air Pollution Control Board,  Texas Air Control Board, Harris
County Pollution Control Department, Galveston County Health  Dis-
trict and City of Houston Department of Public Health,   In  addi-
tion, various industry associations, including (1) Texas Oil
Marketers Association, (2) Maryland Oil  Jobbers Council, (3)  Virginia
Petroleum Jobbers Association, and major integrated oil companies
were also contacted.   Local business and even telephone directories
were used to supplement the inventory.   Telephone, and  personal
inquiries were made to gather these data.
    2.  Physical Description of Plants
      An adequate physical  description of a bulk plant included  the
number and capacity of storage tanks,  whether they were above  or
below ground, the number and capacity  of trucks', and  the type  of
loading used.  The vapor recovery system would be described  by
type, manufacturer and installer.   Bulk plant owners  and operators
were the sources of information.
                                                                       V-l

-------
    3.  Bulk Plant Operations
      Questions to be answered concerning a bulk plant's operation
focused on sales, expenses and profits.  Total gasoline throughput
at the bulk plants, the amount of gasoline transported directly from
the terminal to the customer, and estimates of the amount of gasoline
sold to agricultural accounts and accounts having tanks of less than
2,000 gal  (.7.600  1.), i.e., exempt accounts, were all  information
requested from the operators and owner.  In addition,  to better
assess the financial impact of vapor recovery installations on these
bulk plants, operators were questioned about annual  sales, sales of
other products, margins, operating expenses, gross or  net profits,
total  assets, net worths, long term market, value of the facility
and future of the business.

    4.  Cost of Vapor Recovery
      It was planned to try to determine the cost of buying and
installing each increment of equipment required in the plant and
the cost of modifying trucks.  Among operating and maintenance
costs  were included changes in taxes, insurance and  in the time
required to load or deliver product.
      Cost data were obtained from owners and operators, equipment
manufacturers and contracts.

    5.  Financial  Impact of Vapor Recovery
      The financial impact of installing vapor recovery on specific
bulk plants was examined by seeking fiscal  data from the operators
about  annual sales, expenses, margins, profits, assets, debts,
original investment and current market value.   The owners were asked
for their own evaluation of what each could afford.  An attempt was
also made to learn how the bulk plant owners'  actions  would affect
customers.
                                                                      V-2

-------
      Because only a relatively small  amount of detailed financial
information was available from individual  plants,  financial  state-
ments were created for seven hypothetical, but probable operations,
based upon summary data published by Robert Morris Associates for
bulk petroleum wholesalers.   An estimation of the  financial  impact
of vapor recovery expenses in excess of $10,000 by each of the seven
firms could then be made.  The results and a detailed description
of the evaluating process is in Section VI .  This approach  also
reduced the problems of correlating businesses with substantial
variabilities in sales, profits, rates of return,  etc.

B.  SOURCES OF DATA
      Personal interviews were the principal means of interviewing
people throughout the industry.  Written communications and  phone
contacts supplemented the data gathering portion of this task.
Agencies, individual and associations  contacted included:

            1.  Various state and local air pollution
                control agencies (11)
            2.  Bulk plant operators (59)
            3.  Industry associations  (3 )
            4.  Major oil company representatives  (10)
            5.  Miscellaneous Federal  and state agency
                representatives (5 )
      Data obtained for preceding studies (1, 2) were used again
as background information for this task.

C.  DATA GATHERING IN THE FIELD
      State and local governmental agencies were contacted to obtain
information about air pollution control regulations applicable to
bulk plants, the total gasoline consumption in each AQCR and the dis-
tribution market share for bulk plants, hydrocarbon emission
                                                                       V-3

-------
estimates, plant inventories and  an overview of the agency's
perspective of bulk plants.
      Industry associations were notified of the intended work.
At least one made a substantial  effort to help by discussing the
project in their monthly newsletter and informing members of
planned interviews.
      A standardized group of questions was prepared for inter-
viewing bulk plant operators.  A sample copy is shown in Appendix D.
      Almost all bulk plant operators were contacted on facilities,
throughputs and customers were available.  Financial information
was more sparse, but almost all  operators readily discussed how
vapor recovery would affect them.
      A list of all contacts is  available in Appendix E.
                                                                        V-4

-------
                   VI.   FINANCIAL  ANALYSIS

      Determining the financial  structure and capability of typical
bulk plants is a very difficult matter.   Many of these firms are  in
businesses other than just the wholesale marketing of gasoline.   They
sometimes own gasoline stations and sell tires,  batteries and acces-
sories (TBA) in addition to gasoline and other petroleum products.
It is also quite difficult to define what one means by typical  in
terms of location, customer set, sales volume, additional lines of
business, profitability and asset value.
      Bulk plants operate in market environments that vary in
competition due to the make up of their respective customer sets.
These markets range from being virtually monopolistic to being
highly competitive.  Consequently, a bulk plant  operator must
react in a manner that is sensitive to his environment while con-
sidering the range of alternatives available to  his customers.
      Both bulk plant operators and their customers are prepared
to modify their actions to take advantage of changing market con-
ditions.  The operators will seek to raise prices and curtail  ser-
vices in order to maintain or increase profit margins.   On the  other
hand, their customers will seek to obtain special services and
lower prices for gasoline.  The degree of existing competition  will
be the major determinant in resolving this conflict.   In addition,
the bulk plant operator may sometimes be able to purchase product
from his supplier at a reduced price to enable him to supply gasoline
to a particular group of customers at a given price.
      In an earlier study (1) PES carried out a  financial analysis
of small gasoline bulk plants.  Data gathered in this current study
have generally agreed with the data from the earlier study, and
indicate that the first financial analysis is still valid.  The
Market Analysis and Financial Analysis sections  from reference  (1)
are reproduced in Appendix F of this report for  the convenience of
                                                                         VI-1

-------
the reader.  The analysis showed that the critical financial  factor
was the ability of the plant owner to obtain funds for the initial
investment in vapor recovery equipment of approximately $10,000.
Plants with annual  throughputs less than 600,000 gallons (2,300,
000 liters) are unlikely to qualify for loans.   Firms with assets
between $50,000 and $750,000 were considered from the point of view
of their debt structure, working capital position and profitability
of the enterprise.   Small Business Administration and Pollution
Control Financing Authority loans were considered along with  con-
ventional bank loans.   Tax incentives were evaluated and found to
be of minor assistance unless the firm is enjoying profits.
                                                                         VI-2

                          (As Amended through June 17, 1975)

10.03.38  Regulations Governing the Control of Air Pollution in Area III*

     Pursuant to the authority conferred upon the Secretary of Health and Mental
Hygiene by Article 43, Section 697, Annotated Code of Maryland, 1957 Edition, and
Supplement, the following regulations governing the control of air pollution in
Area III are hereby established as requirements of the Department of Health and
Mental Hygiene.
    Baltimore Metropolitan Area comprising Baltimore City and Anne Arundel, Baltimore,
    Carroll, Htrford and Howard Counties.
     J.  Hydrocarbons Prom Other Than Fuel  Burning Equipment.

         (1)  Definitions for purposes of these regulations:

-------
                         -10-
 a.  "Architectural Coating" shall mean any coating  used for resi-
     dential, commercial  or industrial  buildings  and their  appur-
     tenances ,
 b.  "Motor Vehicle Fuel" shall  mean motor  vehicle fuel  as  defined
     in Article  56, Section 135(b) of the Annotated  Code of Mary-
     land.
 c,  "Organic Material" shall  mean chemical  compounds  of carbon
     excluding carbon monoxide,  carbon  dioxide, carbonic acid,
     metallic carbonates,  metallic carbides  and ammonium carbonates.
 d.  "Organic Solvent"  shall mean  any organic material which is
     liquid at standard conditions and  which is used as  a dissolver,
     viscosity reducer  or cleaning agent.
 e.  "Photochemically Reactive Organic  Solvent" shall  mean  any
     organic solvent with an aggregate  of more than  20%  of  its
     total  volume composed  of  the  chemical compounds classified
     below  or which exceeds  any  of the  following  individuals  per-
     centage  composition  limitations referred to  the total  volume
     of  solvent;
     (1)  A combination of hydrocarbons, alcohols, aldehydes, esters
         or  ketonee any of  which  has an olefinic or cyclo-olefinic
         type  of  unsaturation:   5%.
     (2)  A combination of aromatic compounds with eight  or more
         carbon atoms  to the molecule  except ethylbenzene:   8%,
     (3)  A combination of ethylbenzene, ketones having  branched
         hydrocarbon structures or toluene:  20%.
    Whenever any organic solvent  or any constituent of an  organic
     solvent  may be classified from its chemical structure  into
    more than one of the above groups  or organic compounds,  it
     shall  be considered as  a member of the most reactive chemical
    group, that is, that group having the least allowable  percent
     of the total volume of  solvents.
       For architectural coatings only, the volume of water con-
    tained  in the solvent may be  used  to compute the total  volume
    of the solvent in determining percentages of photochemically
    reactive organic solvents.
 £•   "Reid Vapor Pressure" shall mean the absolute pressure  in pounds
    per square inch determined at 100°F and v/1 = 4 (ratio of vapor
    volume to liquid volume, as defined in ASIM designation D 323-58)
    by using apparatus and procedures as standardized under the auspices
    of the American Society for Testing and Materials.
g.  "True Vapor Pressure" shall mean the absolute pressure  in
    pounds per square inch determined at storage conditions.
    Storage conditions shall be taken as the average monthly temp-
    erature.  If the storage is  subject to  solar  and ambient heat
    gain only, the temperature shall  be taken as  the average monthly
    temperature to a maximum average of 7801-' (average storage temp-
    erature for May through September).  True vapor pressure shall
    be determined by measurement at the storage conditions  or by the
    use of a nomograph, published by the Coordinating Research
    Council and included with these regulations as Figure 1, relating
    true vapor pressure to Reid  Vapor Pressure and storage  temperature.

-------
                              -11-
     h.  "Vapor Balance  Line" shall  mean any connection closed  to
         the atmosphere  between  the  vapor space  of  two  storage  con-
         tainers that will  allow the vapors  to be displaced  as  the
         liquid is  transferred from  one tank to  the other.
     i,  "Photochetnically Reactive Organic Materials" shall  include
         any of the following:
         (1)  Hydrocarbons,  alcohols,  aldehydes, esters or ketones
              any of which  has an olefinic or cyclo-olefinic type
              unsaturation,
         (2)  Aromatic compounds with  7 or more  carbon  atoms,
         (3)  Ketones having branched  hydrocarbon structure,
         (4)  Motor vehicle  fuel with  a true vapor  pressure  greater
              than  1.5 psia  at 78<>F,
         (5)  Organic solvents which have been in direct contact with
              flame in the  presence  of oxygen,
         (6)  Compounds  emitted  from a process in which organic solvents
              are baked,  heat cured  or heat  polymerized in the  presence
              of oxygen.
(2)  Organic Material.
     a*  After January 1, 1973,  a person shall not  cause
         or permit  organic material  having a true vapor pressure in
         the range  of 1.5 to 11  psi  inclusive to be placed,  stored or

 § 52.1082   Rules and regulations.
   (a)  The  requirements of  § 51.22 of
 this chapter are not met  for the  Na-
 tional Capital Interstate Region because
 regulations necessary to implement pro-
 posed stationary control measures for
 gas handling  and  dry cleaning  losses
 have not been adopted. Substitute regula-
 tions  are  promulgated  in  §§ 52.1086,
 52.1087, and 52.1088.
   (b)  The requirements of § 51.22 of this
 chapter  are not met for the  Metropoli-
 tan Baltimore  Intrnstate Region because
 adopted regulations  to  implement pro-
 posed stationary control measures re-
 ferred to in J 52.1073(d) establishing an
 "emission  freeze"  were not  submitted,
 and adopted regulations to control gas
 handling  and   dry  cleaning  emissions,
 measures  referred  to in  $ 52.1073(d),
 were not  submitted  in time  to  be ap-
 proved prior to this promulgation. Sub-
 stitute regulations  for gas handling and
dry cleaning emissions tire promulgated
in 5852.1101. 52.1102, and 52.1107. The
gasoline  vapor recovery regulations  as
promulgated specify a 90 percent reduc-
tion in emissions, thus curing the delect
noted in paragraph (d)  of § 52.1081. A
substitute  regulation for  the  emission
freeze is promulgated in { 52.1112.

  The  requirements of  § 51.20 of this
chapter are not met for the Metropolitan
Baltimore  intrastate' region   or  she
Maryland portion of the National Capi-
tal interstate region because the plan
does not include a discussion of the ade-
quacy of existing State resources and
does not say whether any  additional
State  resources,  including projections
for 5 years, will be required to carry out
any of the proposed transportation con-
trol measures..

tem  or equivalent designed to recover no
less than 90 'percent by weight of the or-
ganic compounds in the displaced vapor.
   (2) If  a  "vapor-tight vapor  return"
system Is  used to meet the requirements
of this section,  the system shall be so
constructed  as to be readily adapted to
retrofit  with an  adsorption  system,
refrigeration-condensation system, or
equivalent vapor removal system, and so
constructed  as to anticipate compliance

              FINANCIAL ANALYSIS EXCERPTED FROM "ECONOMIC
              ANALYSIS OF VAPOR RECOVERY SYSTEMS ON SMALL
                           BULK PLANTS"
6.   MARKET ANALYSIS OF BULK PLANTS
       Bulk plants operate in market environments that vary in
competition due to the make up of their respective customer sets.
These markets range from being virtually monopolistic to being
highly competitive.  Consequently, a bulk plant operator must
react in a manner that is sensitive to his environment while con-
sidering the range of alternatives available to his customers.
       Both bulk plant operators and their customers are prepared
to modify their actions to take advantage of changing market con-
ditions.  The operators will  seek to raise prices and curtail ser-
vices in order to maintain or increase profit margins.  On the other
hand, their customers will seek to obtain special services and
lower prices for gasoline.  The degree of existing competition will
be the major determinant in resolving this conflict.
                                                                         6-1

-------
       A principal  aspect of the bulk plant business that appears
to be self-evident  is that the field lacks consistency.   As implied
previously, there are several owner/operator situations  within the
industry.   Additionally, competition is increasing from  other methods
of marketing gasoline.  These methods include direct dealers and
pipeline facilities.
       For any particular operator, there are relevant factors that
affect his business and have a major influence on its conduct.  These
factors will certainly include the following:
              •  Relationship with his supplier
              •  Efficiency of his plant
              •  Size of his customers
              •  Distance traveled to his customers
              t  Extent of direct competition
              •  Governmental regulations
       These factors  will affect both his gross profits  and net pro-
fits.  For example, if the operator's customers, are relatively dis-
tant his delivery costs will be high.  If he has many small customers,
costs per delivery  will be higher than if he had a few large customers.
       Bulk plant suppliers may not sell gasoline to all of their
customers at the same price.  According to industry practice, an
operator will be able to purchase product from his supplier at a
lower price if he incurs higher than normal expenses in  servicing
his customers.  In  a sense, the opera-tor is being subsidized by
his supplier in order to sell gasoline to a particular group of
customers at a given price.
       During this  study, the question has been raised of independent
operators receiving subsidies for other situations beyond their con-
trol, such as the installation of vapor recovery equipment.  The
almost universal response from both operators and suppliers was that
a lump sum type of assistance could not be expected.
                                                                         6-2

-------
       The operators seem to be left with three possible alterna-
tives: 1) either absorb the added costs, 2) seek lower supply prices,
or 3) raise delivery prices.  An increase in the price of gasoline
raises the further question of an accompanying decrease in demand
and the possible substitutions available to consumers seeking to
purchase gasoline at lower prices.
       Economically, direct supply is viable only for individual
customers located relatively short distances from refineries.  If
long distances must be traveled for any deliveries, costs will begin
to escalate rapidly for individual small users.  Large users, those
with at least 8,000 gallon (30,00.0 li;terl tanks, are likely to deal
with direct bulk sellers or hire trucks to provide deliveries from
the refinery to his facility, bypassing the bulk plant.

7.   FINANCIAL ANALYSIS
     7.1  FINANCIAL DATA AND STATISTICS
       Determining the financial  structure and capability of typical
bulk plants is a very difficult matter.  Many of these firms are in
businesses other than just the wholesale marketing of gasoline.   They
sometimes own gasoline stations and sell tires, batteries and acces-
sories (TBA) in addition to gasoline and other petroleum products.
It is also quite difficult to define what one means by typical in
terms of location, customer set,  sales volume, additional  lines  of
business, profitability and asset value.
       Many firms, both large and small are reluctant to freely  dis-
perse their annual financial  data.  Nevertheless,  sources for this
information are available through Dun and Bradstreet and Robert
Morris Associates (RMA).  The former provides banks, insurance
companies and other institutions  with financial data, corporate  his-
tories and ratings for numerous companies.  PES has obtained several
of these reports for firms in the bulk plant business.
                                                                          7-1

-------
       Robert Morris Associates is a service that publishes summary
data for groups of companies within most Standard Industrial  Classi-
fication (SIC) codes.  For the bulk plant industry, SIC code 5171  was
selected which is defined as follows:
              "Establishments primarily engaged in wholesaling
               petroleum products, including liquified petroleum
               gas, from bulk liquid storage facilities."  *
       RMA has collected financial data for 153 firms within this
classification.  As indicated above, the companies included in this
listing are often in other related businesses in addition  to the
operation of bulk plants.  RMA has published data for companies
grouped according to their asset value.  The groups consist  of 18
companies with assets under $250,000, sixty-seven companies with
assets of between $250,000 and $1,000,000, and fifty-nine  firms with
assets of between $1,000,000 and $10,000,000.  In addition, signifi-
cant ratios by statistical quartile have been computed for the com-
panies within each asset grouping.  These statistics are presented
in Tables 7.1 and 7.2.
       The ratios calculated in Table 7.2 are defined in Table 7.3.
These ratios are commonly used to assess the financial capability
and health of firms as compared to other organizations in  the same
industry.
       Three numbers are depicted for each ratio in Table  7.2.
These values represent the quartile points in each case.  For
example, if a group had 19 members, then the quartile points would
define the values of the fifth, tenth and fifteenth members.  It
is clear from this discussion that management of any company in a
given industry will attempt to keep their ratios away from the
lowest quartile of any group as this might tend to indicate weak-
ness.  By having this type of data, management is able to measure
its performance against others in the same industry.

-------
Table 7.3            DEFINITION OF RATIOS

QUICK RATIO
  Method of Computation;  The total  of cash, short-term marketable
    securities and net receivables for the industry composite was
    divided by the total of current liabilities.
  Result;  The ratio measures short-term liquidity available to
    meet current debt.
  Principle;  Also known as the "acid test" or "liquidity" ratio,
    it is of particular benefit to short-term creditors, as it
    expresses the extent to which cash and those  assets most
    readily convertible into cash can meet the demands of current
    liabilities.  Any value of less  than 1 to 1 implies a re-
    ciprocal "dependency" on inventory or other current assets to
    liquidate short term debts.

CURRENT RATIO
  Method of Computation;  The total  of current assets  for the in-
    dustry composite was divided by the total of  current liabili-
    ties.
  Result;  The ratio is one measure  of the ability of  the in-
    dustry to meet its current debt.
  Principle;  In comparing an individual company  to the industry,
    a higher current ratio indicates that more current assets
    are free from debt claims of creditors and prompter payment
    can be expected.

FIXED/WORTH
   Method of Computation;  The net fixed assets (plant & equipment
    less reserve for depreciation) for the industry was divided
    by the tangible net worth.
                                                                         7-5

-------
 Table 7.3  Definition  of Ratios  con't.

    Result:  The ratio expresses  the proportion between investment
      in capital assets (plant and equipment) and the owners'
      capital.
    Principle:  The higher the ratio, the less owners' capital is
      available for working capital.  The lower this ratio, the
      more liquid is the net worth and the more effective owners'
      capital is as a liquidating protection to creditors.  The
      presence of substantial leased fixed assets—off the balance
      sheet—may deceptively lower the ratio.

DEBT/WORTH
   Method of Computation;  The total debt for the industry composite
     was divided by the tangible net worth.
   Result:  The ratio expresses the relationship between capital
     contributed by creditors to owners'  capital—"what is owed to
     what is owned."
   Principle:   Total  assets or resources  represent the entire
     capital at the disposal  of a given company and consist
     of net worth or owners'  capital,  and creditor capital —
     that provided by those outside the business for temporary
     use.   The proportion existing between debt and worth—or
     leverage—records  the debt pressure.  The lower the ratio,
     the easier the pressure and the greater the protection
     for creditors.

PROFITS BEFORE TAXES/WORTH

   Method of Computation;  The amount  of  net profit before taxes
     was divided by the tangible net worth.
                                                                         7-6

-------
Table 7.3  Definition of Ratios con't.

   Result:  The ratio expresses the relationship between the owners'
     share of operations before taxes for the year and the capital
                                          >
     already contributed by the owners.
   Principle;  Capital is usually invested in a company in the
     anticipation of a return on that investment--!'n the form
     of a profit.  This hope of a profit is the attraction for
     original and new capital.  The higher the profit before
     taxes to worth, the greater is the probability of making
     appreciable addition to owners'
     capital after payment of dividends and taxes.

PROFITS BEFORE TAXES/TOTAL ASSETS

   Method of Computation;  The amount of net profit before taxes
     of the industry were divided by the total assets for the in-
     dustry.
   Result;  The ratio expresses the owners' share of the year's
     operations before taxes related to the resources contributed
     by both owners and creditors.
   Principle;  The relationship indicates the net profitability of
     the use of all resources of the business.
                                                                           7-7

     7.2  FINANCIAL STATEMENT SUMMARY
       Each industry tends to exhibit different types of financial
statements.  For example, the firms in one industry may have a
large percentage of fixed assets while another industry may show
more current assets.  On the liability side as well, firms within
an industry will show similarities and will tend to differ in the
degree of various elements.  Consequently, it is extremely diffi-
cult to compare firms in various industries.  The common practice
is to assess how any given firm in an industry compares to the
averages and standards developed for that industry.
       By reviewing the data for the balance sheets and income
statements given in Table 7.1, some general statements can be made
about the data summarized for the industry.  Most of the data shown
is representative of firms with at least $250,000 in assets.  The
smaller companies have a greater percentage of current assets than
the larger firms with differences appearing primarily in a higher
percentage of fixed assets in inventories and a low percentage of
assets.  On the liability side of the balance sheet, a reasonably
large disparity between the smaller and bigger firms is apparent
in the percentage of non-current debt.  This fact reflects the
greater difficulty in most industries of small firms to obtain
long term debt.
       One further point should be made regarding financial data
on balance sheets.   According to generally accepted accounting
principles, fixed assets always reflect historical cost rather than
their current market values.  Therefore, the balance sheet of a
company may not truly reflect the actual financial capability of the
firm.  For example, a small bulk plant may have been purchased
thirty years ago and the recorded land value will  reflect its
actual cost at that time.  In the intervening period, the market
value of the land may have increased substantially but the firm's
                                                                          7-8

-------
 balance  sheet  and accounting records will continue to carry this
 asset  at its original cost.

     7.3  INVESTMENT  IN VAPOR RECOVERY SYSTEMS
       The approach to be taken  in the following discussion will
 be  to  assess the impact of several expenditure levels for vapor
 recovery equipment on firms of various asset values and sales.
 As  can be expected, within each  group of companies, an irregular
 ability  to accept costs of a given amount will be exhibited.
 The PES  approach will be to evaluate the impact of varying expendi-
 tures  on average firms of several sizes (as represented by data
 in  Table 5.1)  and assess the new quartile position of this firm
 (as represented by the data in Table 5.2).  If any expenditure
 causes the firm to show drastic  and unfavorable changes in parti-
 cular  ratios,  it can  be concluded that the expenditure will have
 an  adverse effect on  the enterprise.  This is due to the fact
 that such changes indicate the probable existence of strains on
 the financial  capabilities of the firm in such areas as availa-
 bility of capital, profitability and borrowing potential.
       The analysis described below will concentrate on firms with
 assets of between $50,000 and $750,000, and will be concerned
 principally with the debt structure, working capital position
 and profitability of an enterprise.  These firms can be expected to
 require  an  investment of at least $10,000 for installation of a top
 loading  vapor balance at plant sites and for modification of their
 delivery  trucks.   Although it is recognized that some plants may
 need to  convert their own transports, this $5,000 expenditure
 (approximate) is  not being included as a cost of installing vapor
 recovery equipment.   Also,  plants which elect to convert to bottom
 loading at a cost in  excess  of $30,000 will  be considered as volun-
tarily  making this  expenditure  as a facility modernization.
                                                                          7-9

-------
     7.4  SOURCES OF CAPITAL
       Most companies in the asset range being considered will be
unable to raise the needed capital internally and will have to
seek outside sources of funds.   The most likely organizations
available to provide this assistance will  be banks.  Other assist-
ance may be expected from the Small Business Administration (SBA)
and the Pollution Control Financing Authority (PCFA) in most states.
The latter have been organized  to provide low interest loans to
industry in order to purchase and install  pollution control equip-
ment.  However, only in the State of California has this organiza-
tion been specifically attempting to assist small  businesses.
       On June 4, 1976 President Ford signed Senate Bill 2498 into
law (Public Law 94305)  which provides the SBA with the capability
to guarantee contracts that the California PCFA has with businesses
including loan agreements.   These contracts are then used as
security to sell  tax exempt bonds primarily to banks who make loans
to firms needing to install pollution control equipment at reduced
rates.   If this program proves  successful, it will probably be
expanded to other sections  of the ocuntry.
       When a potential  borrower seeks a loan, he must demonstrate
to his bank that he possesses the capacity to repay the principal
and interest in a reasonable time period.   If he cannot demonstrate
this fact, neither the SBA nor the PCFA can grant him a loan.  His
credit worthiness is determined solely by his bank.
       In most usual circumstances, banks will make equipment
loans for a period of three to  five years at the prevailing rate
of interest.  This rate is  presently about 11%, however, it is
subject to change depending on  the size of the loan, the type of
equipment and the credit worthiness of the borrower.  If the loan
applicant qualifies under SBA or PCFA criteria, he could obtain
a loan for eight or more years  at an interest rate that is three
or four percent below the prevailing rate.
       Recently, the SBA has also recognized the special hardships
that can be created for small businesses in meeting air pollution
                                                                          7-10

-------
regulations.  Accordingly, a program of air pollution control loans
has been instituted.  Further information pertaining to this pro-
gram, was provided in Reference 1.

     7.5  ANALYSES OF FINANCIAL CAPABILITY
       In order to assess the financial capability of typical small
firms in the industry, seven pro-forma balance sheets and income
statements have been created for enterprises with selected levels
of assets and sales.  These statements, as shown in Table 7.4 ,
represent companies with assets ranging from $50,000 to $750,000
and with total annual sales between $150,000 and $2,500,000.  These
statements were developed from the data provided in Tables 7.1 and
7.2.
       From these data, ratios for total debt/net worth of the
seven typical companies have been generated assuming different levels
of vapor recovery expenditures.   These new ratios are shown in
Table 7.5 for two cases.  In the first case the loan is made for 80%
of the designated amount - a 20% down payment being required.  The
second case shows 100% financing available, because of guarantees
by the SBA or the California PCFA.  When the debt/net worth ratio
reaches the 2.5 area, it indicates that the firm is maintaining a
high proportion of debt.  At this point creditors of this company
will begin to become concerned about its credit worthiness.  Any
additional  borrowing will become extremely difficult unless the
debt/net worth ratio can be reduced.  For this reason a ratio of 2.2
will be considered as a desirable maximum.
       Working capital must also be considered in order to assess
the capability of an enterprise to make a down payment, if necessary,
and continue in operation while paying off the loan.  Quite clearly,
all working capital  cannot be diverted to loan purposes.  For this
exercise let us assume that 50% of working capital  can be diverted.
                                                                          7-11

 Many organizations are likely to find this  amount too  high  and could
 result in causing them cash flow difficulties.   Nevertheless,  50%
 appears to be a reasonable jumping off point.
        With this factor in mind, one can estimate the  maximum  loan
 a firm can undertake based solely on working  capital from banks or
 through the SBA or PCFA for the seven typical  companies  as  follows:
                     50% of
                     Working              Maximum            Maximum SBA
                     Capital             Bank  Loan           or PCFA Loan
$ 50,000             $ 4,125             $  0                  $ 25,000
 100,000               8,250                15,000                50,000
 150,000              13,375                30,000                75,000
 200,000              16,500                35,000               IOC,000
 300,000              25,950                60,000               150,000
 500,000              43,250               100,000               150,000
 750,000              64,875               150,000               150,000

        Since a minimum of $10,000 is considered necessary for
 installation of a complete vapor recovery system for incoming and out-
 going loads, any acceptable loan below this amount is  shown as zero.
 Additionally, SBA and PCFA loans of larger amounts can be supported
 since they may not require down payments, and are to be repayed
 over longer time periods at lower interest rates.
        Finally, profitability must be considered since the  enter-
 prise must generate the earnings to replenish working  capital  and
 make loan payments.  Realistically, no lender will be  confident in
 making a loan unless principal and interest payments are covered by
 the potential earnings of the enterprise.  Accordingly, the firm's
 net income will determine the amount of loan  that may  be granted.
        Under usual circumstances, an investment in plant and equip-
 ment is made in order to replace worn out facilities,  modernize
                                                                         7-14

the establishment, or improve operating efficiencies.   The result
of this type of investment is reasonably expected to be increased
profitability.  It is these higher profits that are then used to
repay the principal and interest of any loan undertaken for the
purpose of making this investment.  In the case of vapor recovery,
this scenario cannot be expected.  Rather, any debt incurred for
the purpose of meeting vapor recovery regulations will  have to be
honored from non-rising profits.
       The profits of any business are used to provide  a return to
its owners and for reinvestment in the business.   Consequently, it
is unreasonable to expect that all of the profits of the business
should be employed for vapor recovery purposes.  Every  company must
constantly reinvest in its plant and equipment in order to maintain
adequate operations.
       Again, let us assume that no more than 50% of after tax
profits can be utilized for loan repayment.  This procedure provides
for a minimum level of profits to be used for purposes  unrelated to
the vapor recovery installation.
       Given this background, the maximum loans that can be expected
for the seven typical companies are as follows:
                     50% of

These estimates have been based solely on the amount that can be
repaid from previous year's profits and do not include the effect
of any special tax incentives.
       Tax incentives may have a significant impact for many com-
panies contemplating a vapor recovery investment.  In this connec-
tion, the Internal Revenue Code includes special provisions for
firms, and especially small businesses purchasing and installing
certified pollution control facilities.  In addition to all interest
payments being deductible expenses for tax purposes, Section 169 of
the code permits a rapid write-off of such certified investments.
Under this regulation a company may choose to depreciate its newly
acquired facility over a sixty-month period instead of over its use-
ful life.  Employing the straight-line depreciation method, 20% of
the cost of this investment could be deductible for five years.
       Sections 46 and 50 of the code deal with the subject of
investment tax credits.  Under the 1975 provision, all  businesses
may credit 10% of the cost of equipment with a depreciable life of
at least seven years to their actual tax liability.  Lesser per-
centages may be created for equipment depreciated over a minimum
period of three years to a maximum of six years.  The purpose of
this regulation is to provide businesses with added incentives to
purchase equipment.
       Finally, Sections 179 of the code furnishes small  business
with an additional, opportunity to reduce their taxes.  It permits
an added first year bonus depreciation allowance equal  to 20% of
the purchase price of the equipment.
       Accordingly, a small business will be able to deduct its
interest expense plus almost 50% of the purchase and installation price
of certified pollution control equipment, depending on the depre-
ciation method used.  Other businesses will be able to deduct 30%
plus interest charges.
                                                                            7-16

       The primary benefit resulting from these  incentives will
be a reduction in the tax burden on the affected companies.  Con-
sequently, firms with little or no profits will  accrue only minor
assistance from these regulations.  For firms enjoying profits,
they will benefit from sharply reduced tax expenses and an increased
cash flow.  The latter will provide additional security to financial
institutions contemplating loans to the firm and may result in the
business being able to spend larger sums on pollution control equip-
ment.
     7.6  DETERMINATION OF LOAN LIMITS
       In order to be eligible for a loan, a company must be able
to demonstrate that its financial structure is able to absorb addi-
tional  borrowing, that it possesses the working capital to make
the required down payment and pay the associated fees, and that it
has the earnings capacity to maintain its financial capability and
retire the loan.   These aspects have been considered above for our
typical companies in relation to various size loans.  We can now
combine the results above and determine approximately the maximum
amount each size firm can be expected to borrow.
       This estimate has been calculated by computing the minimum
acceptable loan amount for each size company and  then choosing the
smallest amount in each group.   The data resulting from this pro-
cedure  are shown  in Table 7.6.   The amount that can be borrowed
for each asset group is then equal  to the smallest value in that
group as follows:
                                                                         7-17

       It should be reemphasized that these amounts  reflect estimated
maximum investments for the typical  firms based on the  specified
assumptions.  These assumptions are  believed to reasonably reflect
the real  world situation,  but they are susceptible to ^interpretations.

 IB. ABSTRACT
 This study surveyed   bulk plant  operations  in  areas surrounding  Baltimore, MD,
 Washington, D.C., and Houston/Galveston, TX.   It was performed  to determine whether
 the descriptive, market and economic data  presented in an earlier report
 adequately applied to other areas of the country.   For these specific locations
 data was obtained to:l)Provide an inventory  of  bulk plants and  classify these plants
 by thoughput. 2) Describe facilities and vapor  recovery equipment at  the bulk plants.
 3)Determine types of  customers and volume  dispensed to non-exempt accounts,
 agriculture accounts  and accounts with small  tanks.
 4)Financial profile of typical bulk plants.
