types composing over 20 percent of the load.  The mixed refuse
category shall be used when no predominating load types can be
Load Volume -- circle the number which best approximates the
volume of the load in the truck.  "No bad" is used to record
the empty weight of the truck and driver.
Weather -- circle the number which best describes the
predominating weather for the run.  Intermittent drizzle or
snow flurries shall be reported as "dry."
After the weigh card is completed, the driver initials the
bottom line and bands together that run's weigh card with the
appropriate collection cards.  At the end of the day, the
driver turns in that day's information card bundles to his
route supervisor who forwards the material to the survey
Single Waste Stream Analysis, Step 5.  Sort the collection cards by
building number(s) and place them in chronological order.  The loose yardage
volume generated between collections is determined by multiplying the can size
by the percentage of load volume.  An approximate value of the collected
weight is determined by multiplying the loose yardage volume by the appro-
priate bulk density values.  Composition of the single waste stream is
determined from the "Load Type" section on the collection card, or by using
composition percentages.  If a collection run is confined to a particular
facility grouping (as family housing), the appropriate weigh card can be
isolated and used to provide weight, volume and composition information.
Installation Total Waste.
(1)  Step 6.  The volume and weight estimates, derived from the
analysis of the collection cards in Step 5, are summed over all the
"single waste streams" to provide total weight and volume estimates on
the collection points.  Sum the net weights (loaded weight minus no
load) from the weigh cards to arrive at the total collected weight.  The
loose yardage volume of each compactor truck is determined by
multiplying the compactor's capacity by the load volume (percent) and
the compaction ratio.  Multiply non-compactor truck capacities by the
load volume (percent).  Sum the calculated volumes of all collection
runs to determine the total volume.  The bulk density of each collection
run, or total installation waste, can be determined by dividing the net
weight by the loose-cubic-yard volume.  "Composition" information can be
obtained from weigh cards by converting load type volumes to load type
weights, and dividing by the sum of the adjusted refuse weights for all
collection trucks.  Load type weight is determined by multiplying load
type volume by the appropriate load type bulk densities.  Component
weights of the solid waste materials can also be derived by multiplying
the total weight by the installation composition percentages.
(2)  Step 7.  As a check on the survey operation, make preliminary
calculations of the weights and volumes (as per Steps 5 and 6), using
