antifreeze or deicing fluid for proper protection and record results. The roof drain valve must
be secured and will have a sign attached to it stating:
CAUTION - WINTERIZED - DO NOT DRAIN
FREQUENCY: As Required.
10.3.3.3. Tank Inspection/Cleaning Requirements (Aviation Products). Operating and bulk
storage tanks have identical inspection/cleaning frequencies. Follow governing environmental
regulations if more stringent. Complete AF Form 172 and submit it to the MAJCOM fuels
facility engineer.
10.3.3.3.1. Tanks without an inlet F/S, micronic filter on the inlet, or internal coating.
FREQUENCY: Every 4 years.
10.3.3.3.2. Tanks with F/S or micronic filter on the inlet or internal coating.
FREQUENCY: Every 6 years.
10.3.3.3.3. Tanks with F/S or micronic filter on the inlet and internal coating, or built to the
standard design.
FREQUENCY: Every 8 years. This may be extended to coincide with the API 653 out-
of-service inspection every 10 years after the first inspection is completed.
10.3.4. Tank Vacuum and Pressure Vents. Inspect, clean, and repair. Where applicable, inspect
antifreeze levels in the spring and fall. A mixture of equal parts of water and antifreeze will be used.
FREQUENCY: Semi-Annually.
10.3.5. Dikes.
10.3.5.1. Earthen.
10.3.5.1.1. Inspect for signs of erosion and vegetation.
FREQUENCY: Annually.
10.3.5.1.2. Use fireproof chemicals for sterilization of dikes and basins to prevent growth of
vegetation. Work should be done by BCE entomology personnel or by contract.
FREQUENCY: As required.
10.3.5.2. Concrete, Asphalt, or Cement Brick. Inspect condition and repair as required.
FREQUENCY: Annually.
10.3.6. Piping.
10.3.6.1. Pressure Test. Pressurize all on-base fuel piping systems using existing system pumps.
When conducting the test, follow the guidance outlined in paragraph 2.3.3.1.
FREQUENCY: Annually.
10.3.6.2. Hydrostatic Test. Perform a hydrostatic pressure test on all underground fuel transfer
lines. Product is normally the test media. Details for conducting the test are provided in
paragraph 2.3.3.2. Consult your fuels facility engineer for guidance on completing this
requirement. The fuels facility engineer is the approving authority for all waivers of this
requirement. Dual pressure temperature compensating pressure test methods may be considered
with approval from the MAJCOM fuels engineer. This method may allow the test to be
conducted faster with fewer blind flanges than the traditional hydrostatic pressure test described
in paragraph 2.3.3.2.
FREQUENCY: Every 5 years.
10.3.6.3. Exposed Piping.
