Dear Mr. Billings:
Thank you for the second biennial compliance report on the
former Federally owned surplus property known as the Former
Atlas "E" Missile Site, C-COLO-501A.
The report has been reviewed and compared with your previous
biennial report. It indicates that you are developing and
maintaining the property in a satisfactory condition. There-
fore, we are pleased to advise you that the report is acceptable
and fulfills the compliance requirements for the past two-year
reporting period.
In addition to accepting the biennial report, a representative
of this office may make an on-site inspection of the property in
the near future. We will notify you in advance of our inspection
schedule.
Sincerely,
t-

Dear Mr. Olson:
SUBJECT: WELD COUNTY MISSILE SITE STORAGE FACILITY
At your request, we have prepared a report which outlines requirements
regarding heating, ventilating, humidity control and fire protection
to be made to the underground missile site storage facility.
In preparing the report, we made the following basic assumptions:
1. The office area of 1,900 square feet next to the storage
vault will be inhabited by County personnel on a more or
less regular basis.
2. The records to be stored are of great value to the County
and storage life is over one hundred (100) years.
3. Underground areas other than the large storage vault and
adjoining office area are not considered in this evaluation.
Our estimate to perform the necessary engineering as outlined in the
report is as follows:
Architectural Project Manager 40 hours at $22.50/hour
Mechanical Engineer 140 hours at $24.50/hour
Mechanical Design/Draftsman 40 hours at $16.00/hour
Electrical Design/Draftsman 40 hours at $18.50/hour
It is important to note that the complexity and cost of the engineering
services is directly related to the degree of protection desired. We
propose to design a sophisticated mechanical and electrical system

which will give you the maximum protection of the documents possible
with today's technology. As you are aware, there are less expensive
systems available than the one which is proposed and they offer a
lesser degree of protection.
If you wish further clarification regarding our proposal, please
contact us.
Sincerely,

PROPOSED MODIFICATIONS TO THE
WELD COUNTY MISSILE STORAGE FACILITY
Prepared by CNC/NHPQ April 5, 1976
The portion of the missile site under consideration by this report includes
the following:
1. The 54' x 54' archives storage vault room
2. The 54' x 36' office space adjoining the storage vault room.
3. The access tunnel from the office space to the outside.
This report does not consider the remaining underground areas of the missile
site. Note that if any of these remaining underground areas are to be used
for any purpose by personnel, a seaparate study should be made similar to
this report.
Our recommendations are organized into the following categories:
A. Air Conditioning
B. Fire Protection
C. Personnel Protection and Life Support Systems
D. Records Management
A. AIR CONDITIONING
Recommendations : 1. The 2900 sq. ft. archives storage vault shall
be temperature controlled to 65° F ± 5° F and
humidity controlled to 50% R.H. maximum 24 hours/
day year round. Adequate outside air ventilation
shall be provided to support 2 personnel in the
vault. High efficiency filtration shall be
provided for the air supply.
2. The adjoining 1900 sq. ft. office area shall
• be air conditioned to 70° F + 5°F and 50%
maximum relative humidity when occupied. Adequate
outside air ventilation shall be provided to
support 10 personnel in the office area.
Clarification: 1. Temperature and humidity control in the storage
vault are required to prevent formation of fungus
(mold) and bookworms which can destroy both paper
and film documents.
r
B. FIRE PROTECTION
Recommendations: 1. Both the 2900 sq. ft. archives storage vault
and the adjoining 1900 sq. ft. office space
shall be protected by an automatic wet type
sprinkler system.
2. Interior standpipe hose stations shall be
provided in the office area adjacent to the
storage vault.
3. All areas shall be provided with an early
warning type fire detection system wired to
an internal fire detection system, to the
site supervision trailer and to the nearest
fire department having jurisdiction.
4. Water type portable fire extinguishers shall
be strategically located in the office area
adjacent to the vault and at the tunnel
entrance.
Clarifications: 1. The wet type automatic sprinkler system for
the vault is a recommendation only and not a
specific code requirement. In this type
system only the sprinkler head or heads in
the immediate fire area are activated, there-
by minimizing water damage. The automatic
sprinkler system for the office area is
required by code.
2. The interior standpipe hose stations are for
the use of personnel and the fire department
in case the use of the portable fire extinguis-
hers and the automatic sprinkler system are
ineffective.
3. The early warning type fire detection system
will detect the presence of smoke prior to
the actual outbreak of a fire. This system
will alert personnel in the underground areas,
the vault supervisor in the trailer, and the
nearest fire department. This alert feature
is necessary in order to extinguish a fire
at its earliest stages and to protect human
life.
4. The portable type fire extinguishers are
necessary to quickly extinguish a fire. Note
that water type are recommended and not carbon
dioxide for this use.
• It may appear that the recommendations for fire protection are
excessive in light of the fact that the records are stored in a
fire proof vault. The recommendations, however, are justified
when the following are considered:
a. The archives to be stored are the fuel source.
b. The open shelving technique of storing is very conducive to
fire spread.
c. Source of ignition for a fire can come from personnel care-
lessness, arson, malfunction of electrical and air condition-
ing systems, lightening, etc.
d. Considering the apparent value of records to be stored and
the length of storage, even one fire in 200 years could be
disastrous, if not properly controlled.
C. PERSONNEL PROTECTION AND LIFE SUPPORT SYSTEMS
Recommendations: 1. The early warning type fire detection
system described in item B.3 above.
2. Battery powered emergency lighting shall
be installed in the storage vault, office
area, and exit tunnel.
3. Stairs for an existing emergency exit roof
hatch in the office area shall be provided.
4. Plumbing facilities shall be reinstalled in
the existing office area toilet room. A
new sewage lift station shall be provided.
5. The newly installed storage racks shall be
modified to provide ,a maximum storage height
of 12'-0" and to provide no dead-end aisles.
6. A second means of egress shall be provided
out of the storage vault by addition of a
door at north end opening into office area.
7. Panic hardware must be installed on storage
vault doors , and the tunnel exit door.
8. Ventilation air shall be required. Refer
to recommendations A.1 & A.2.
9. Air conditioning systems noted in recommen-
dations A.1 & A.2 shall have manual provisions
for changeover to 100% outside air to assist
in smoke removal, if required.
r I\
Clarification: 1. All recommendations n.,ced above are to
protect and sustain personnel working in
the underground storage and office areas.
D. RECORDS MANAGEMENT
Recommendations: 1. Microfilm should be stored in class 150-4 hour
rated insulated record containers.
2. Enclosed steel containers with ventilation
openings should be used for valuable records
storage instead of open shelving.
3. Records should be segregated in the storage
vault according to value.
4. Under no circumstances shall cellulose nitrate
film be stored in this facility.
5. Smoking should not be allowed.
6. The fire department having jurisdiction should
regularly review status of site.
7. All non-essential material should be eliminat-
ed from storage vault.
Clarifications: 1. The recommendations above involve safe-guard-
ing the archives against possible damage due
to fire.
2. Recommendation No. 4 above involving the
exclusion of nitrate film from this facility
is very important. Nitrate film ignites
spontaneously, burns violently and produces
toxic gases. A survey must be made by the
county to insure that none of this material
is stored (e.g. early motion picture films,
etc. ).
