SUBJECT
port for Yearend Funding for Salt Shed
Replacement
1. This memorandum is to request FY 1976 yearend funding for
replacement of the Salt Shed in the West Parking Lot at the rear of
the Powerplant. It is presently budgeted for action in FY 1978 in
the amount of $75,.
2. The present shed is of cinderblock, wood, and sheet metal
construction. The interior is used primarily for bulk storage of
sodium chloride with a small portion set aside for electrical con-
trols for the parking lot lighting. Send is stored in a bin on the
west wall of the shed.
3. The problem with the existing facility is multifaceted.
The building at best would be unattractive, but in its poor state
of repair is ostensibly unacceptable. More important are the
safety aspects relating to the busy, blind corner created by the
three-way intersection, plus the wet, salty switchgear room which
constitutes an electrical hazard. In addition to the above, con-
siderable parking lot drainage runs off in the immediate vicinity
with resultant leaching of chemicals away from the storage and into
the storm drains.
4. The General Services Administration is currently engaged in
executing a circa 1969 project to upgrade the West Parking Lot light-
ing at which time the electrical devices will be removed from this
shed. The Real Estate and Construction Division, 0L, has identified
an elevated storage bin to be located in the Powerplant area which
will hold sufficient material and make it possible for spreader
trucks to be gravity loaded. Other means and locations for reloca-
ting the Salt Shed were considered but were either labor or mechan-
ically intensive or inconveniently situated for operational require-
ments. A study detailing considerations for Salt Shed relocation and.
recommending an elevated storage bin is attached for your information.

PRELIMINARY REPORT ON: ROAD ICE CONTROL
CHEMICAL STORAGE FACILITIES STUDY
1. GENERAL DISCUSSION
In January 1976, subject study was initiated to develop an alternate
solution to the several proposed relocation schemes of the present Ice
Control Chemical (Salt) storage facility from the present building located
at the southeast corner of the West Parking Lot.
All said proposals recommend either construction of the same type of
facility at other sites or adaptation of other facilities for salt storage
use.
The difficulty in selecting an acceptable site for the in-kind re-
placement facility stemmed primarily from its relatively large area
requirement for truck loading operation and difficulty of effectively
camouflaging''such type industrial activity from either ajoining properties
or the main building. The few areas where this could be accomplished
presented access problems such as operationally unacceptable steep
grades or, as in the case of location adjacent to the existing sewer
pumping station, indirect access via county and state roads through
residential areas.
The only existing facility that could be made available and be
adapted/altered for salt storage use is the covered parking facility
adjacent to the Garage. It was recommended to enclose required number

g q ~'iIs proposal was considered
undesirable for the following reasons:
A. It would result in reduction of covered vehicle
parking assets required for the maintenance garage operations.
B. The adjacent area between the structures and even at
the end of the structures is considered insufficient for safe
loading operation involving spreader trucks and front-end
loaders. For proper loading operation, a loading ramp should
be provided . Room for construction of such ramp does not
C. The loading operation utilizing front-end loaders to
load trucks from a bulk storage pile results in substantial
contamination of the adjacent area with chemicals. Such con-
dition is unacceptable in the midst of a Vehicle Maintenance
.This study has enlisted the cooperation and received assistance
from the Federal Highway Administration and Salt Institute. Extensive
bibliography describing the latest throughts on the subject was collected
and was used as the basis for findings and recommendations. The listing
of the bibliography used for this study,is enclosed with this report as
Attachment A.
Although the initial charter of the study was limited to the siting
and design of the replacement chemical storage building, this study had
to be expanded'to include the entire spectrum of the Ice and Snow Control
operation as the methods used for Ice/Snow Control determine the size and
type of facility required. The storage facilities and the methods of opera-
tion are interdependent. Storage facilities limit the choice of methods aJ

and recommendations shall.be made in the final report. Certain prelim-
inary observations are to be doublechecked to insure absolute accuracy.
II. PRELIMINARY FINDINGS AND RECOMMENDATIONS
USE CHEMICALS FOR ICE/SNOW CONTROL
Findings
Presently sodium chloride (salt) in heavy doses
is used almost exclusively to maintain roadways in
clear pavements condition. Peletized calcium chloride
is used for clearing the sidewalks. Abrasives (sand),
for all practical purposes, are not utilized.
Sodium chloride is the most economical, most
effective and widely used ice control chemical to
attain clear pavement conditions. Its' effects on
environment and dangers due to contamination are
minimal. The main environmental concerns are: con-
tamination of the water supply and the minor effects
on vegetation.
Calcium chloride contamination has lesser effects
pn water supply and similar effects on vegetation. It
is; however, more expensive especially if purchased in
bagged form (current practice).
2. Recommendations
As the clear pavement conditions are desirable and

Approved For Release 2001/07/16 CIA-RDP79-00498A000100110001-7
icals cannot and should not be eliminated. However,
by instituting operational controls, training of
snow/ice control crews, establishment of advanced
methodology.of chemical application, calibration of
equipment, etc., the amount of chemicals used could
be substantially reduced achieving same results. The
environmental impact of use of chlorides by the Agency
is negligible as the surface runoff from its property
discharges almost directly into the Potomac River only
a few miles above the tidal limits. Because most of'.
the paved areas and roadways are curbed and served by
storm sewer systems the effects of chemicals on the
vegetation by properly controlled application methods
and procedures can be minimized.
B. TYPE OF CHEMICALS NEEDED FOR ICE/SNOW CONTROL
Findings
Problems of lumping of the bulk stored sodium chlo-
ride and freezing of the sandpile have been reported.
This is primarily due to semiexposed storage of the
sodium chloride as the door of the shed is normally open
and part of the pile is totally exposed to weather (see
photographs, Attachment B). Also it is suspected that
sodium chloride procured for our use does not contain
anti-lumping agents. Our sandpile is open to weather,

Approved For Release 2001/07/16 : CIA-RDP79-00498A000100110001-7
Is in constant saturated state, and as no antifreeze
2. Recommendations
Because of our relatively small requirements, and
inadvisability of having mixing facilities, both from
economical and land-use viewpoints, it is recommended
that commercially available products and mixtures be used
in snow/ice control. Sodium chloride treated with
anti-lumping agents should be used for both roadway.and
agents are added, freezes during periods of cold weather
when its use would be most beneficial.
With deicing agents (sodium chloride at 20:1 proportion)
already mixed in. All materials should be stored in
totally weatherproof facilities. Use of sand, because of
sidewalk deicing. Bagged sodium chloride should be used
only at entrances and steps. More emphasis should be
placed to timely plowing and measured mechanical appli-
cations of deicing chemicals on roadways and the pedes.-
trian walkways. Sand should be procured from suppliers
its large quantities required for even limited effective-
ness and its tendency to cause problems within the storm
sewer systems, should be limited to the intersections and
steep grades. Sand should be used as an additive treatment
In order to accelerate deicing action of sodium chloride
under the extreme cold conditions (below 20? F.) prewetting
of sodium chloride with liquid calcium chloride solution is
recommended. Only minor modifications to our presently owned
and not as a substitute for chemical treatment.

C. STORAGE FACILITIES
1. Findings
The present facility is inadequate from both
economical and operational standpoints. It does not
provide adequate weather protection for the ice/snow
control material stock piles; truck loading operation
is unwieldly and inefficient due to site limitations;
shed configuration prevents utilization of old stock;
difficult loading conditions exist due to lack of ramp,
etc. In addition, the site is totally unacceptable.from
the esthetic viewpoint. The existance of electrical
switchgear in close proximity of the chemicals could be
construed to be a safety hazard.
The existing salt storage shed is approximately
20' X.50' block/frame building normally containing ap-
proximately 200 tons of bulk sodium chloride. There is
evidence (the material in the back of the shed appears
not to have been disturbed for a number of years) that
the stock is more than adequate even under present high
.usage rates. The bagged material that is also stored
within the shed is not used as it is unaccessible. New
,stock of bagged deicing material stored elsewhere is used
for sidewalk and entry way deicing.
In a typical present operation front-end loader and
a spreader truck is mobilized and brought to the material
storage shed. While the front-end load operator loads the

off the truck scattering around the site. Then
while the truck driver operates the truck, the equip-
ment operator rides in the back of the truck observing
the discharge of chemicals (not required if equipment
is properly maintained and calibrated).
2. Recommendations
In order to reduce the response time which is
critical for effective ice/snow control, automating
..the loading operation is recommended. It- is recom-
mended that this would be accomplished by constructing
elevated overhead hopper-type storage facility. Illus
trations of this-type of facility are attached hereto
as Attachment C. This type of facility would eliminate
the requirement for the front-end loader and its opera-
tor. After positioning the truck under the hopper,
the truck driver could easily load the vehicle by operat-
ing the power assisted clamshell gates. Sand or salt
at rates controlled by variations in gate openings would
be deposited directly into the truck by gravity. Most
important, it would allow salting operations to begin
almost immediately and to reduce the overall time required
to complete the entire operation. Such operation would be
relatively clean, minimizing ground contamination, and
thus, the cleanup requirements in the immediate vicinity.
It is estimated that, with the institution of con-
trolled chemical application rates and other controls to
Approved For Release 2001/07/16 : CIA-RDP79-00498A000100110001-7
Approved For-Release 2001/07/16 : CIA-RDP79-00498A000100110001-7
eliminate excessive chemical usage, the annual calcium
chloride requirement to maintain the roads and other
paved areas in relatively adequate "clear pavement" con-
dition is only about 75 tons. An additionaly 25 tons of
sand treated with antifreeze agents should be maintained
for additional treatment of dangerous areas. Tank storage
and dispensing facilities for approximately 100 gallons of
calcium chloride brine solution for prewetting of sodium
chloride should also be provided.
In view that -standard self-supporting steel bins
meeting our storage capacity requirement are commercially
'available from several manufacturers their use is recommended.
Use of standard manufactured product is considered more eco-
nomical than any custom design built-in-place system. A
brochure of such a prefabricated bin is attached as Attach-
ment D. Recommended size and other features are circled.
The bin is to have two compartments with two separate gates
for storing and dispensing both salt and sand. Interior will
be.protected with an anticorrosive coating. Charging of the
hopper would normally be accomplished once per year during the
summer months. However, a conveyor system is recommended to
.charge the hopper as it would be too costly to set the struc-
ture totally into the hillside to allow direct loading from
the delivery trucks (see drawings in Attachment E). Although
many salt delivery trucks are equipped with pneumatic offloading
equipment, we would still have a problem of resupplying our
sand requirements without said conveyor system.

1. Findings
.As previously stated, the present site is totally un-
satisfactory. The key elements of the site are as follows:
a. Safety - Good site distances and adequate
equipment operational area. Access roads should not
open directly into heavily used roads. Site should
be relatively hazard free (especially of the hazards
that may be covered with snow). The site should be
adequately lighted and-posted to warn motorists of
truck traffic.
b. Accessibility - Storage site should permit
easy access and maneuverability by trucks and other
equipment used.
c. Tidiness - Storage facilities should be as
unobtrusive and attractive as possible and be shielded
from view of the nearby roads.
d. Drainage - The storage facilities should be
adequately drained to prevent soil, surface, and sub-
surface water contamination by the chemicals.
Recommendations
The proposed site as shown on Attachment E is ideal from
,several respects. The steep grade allows the facility to be built

loading operation, but also to meet the low profile requirement of the
present facilities planning policy. It is adjacent to an industrial
site and with minimal architectural treatment it can be made to look
like the powerplant or the cooling tower structures. Stucco treated
panels inset or attached to the structural steel required to support
the hopper and the roof over said hopper are recommended. The cost of
providing access both for the supply trucks and for the salt spreading
trucks from the Powerplant yard are minimal.

IV. -EQUIPMENT REQUIREMENTS
1. Findings
Thorough analysis of the present snow/ice fighting equipment
.assets has not been completed. The mechanical condition, sufficiency,
adequacy, efficiency, and other factors are as yet to be delved into.
However, the present equipment including salt spreading trucks can be
used without modification in conjunction with the proposed salt/sand
storage and loading facility.
2. Recommendations
Continue with the study and report findings and recommendations.
IMPLEMENTATION OF RECOMMENDATIONS
At this stage of the overall study only the implementation of the
recommended salt storage facility can or should be discussed.
i
The overall scope of the project-is such that the construction has
to be accomplished by a contract. The bins and other related equipment
could be purchased separately and provided to the contractor as G.F.M..
This action is recommended as it would most likely result in savings,
would enable us to use end of year funds if available, and would mini-
mize the potential change orders to the construction. contract resulting
from minor differences in dimensions and configuration of the standard
products as produced by different manufacturers. There are numerous
manufacturers of said hoppers and we could not legitimately eliminate
any one of them from consideration. Advance knowledge of the physical
characteristics of the product chosen is almost absolutely required for
development of construction drawings.
