Provide CPS and protective coatings for the following buried or
submerged metallic utility systems regardless of soil or water corrosivity:
1)
Petroleum, Oil and Lubricant (POL) pipelines.
2)
Oxygen pipelines.
3)
Underground POL and gasoline storage tanks.
4)
Underground hazardous substance storage tanks.
5)
All water storage tanks interiors.
6)
Other system's defined by the NAVFAC EFD/EFA's / USACE
DISTRICT's Corrosion Control Coordinator.
Provide a CPS and bonded protective coatings on other buried or
submerged new steel, ductile iron, or cast iron utility pipelines not
mentioned above when the resistivity is below 30,000 ohms at the
installation depth at any point along the installation. Do not use unbonded
protective coatings such as loose polyethylene wraps. Provide joint
bonding on all ductile iron and cast iron installations.
When an existing CPS is being modified or extended, the new CPS must
be compatible with the existing CPS system. When plastic pipe is
selected to replace or extend existing metallic pipe, thermal weld an
insulated No. 8 AWG copper wire to the existing pipe and run the full
length of the plastic pipe for continuity and locator tracing purposes.
The CPS must provide protective potentials according to the requirements
of the National Association of Corrosion Engineer (NACE) Standard
RP01-69 (latest revision), "Control of External Corrosion on Underground
or Submerged Metallic Piping Systems" and NACE Standard RP02-85
(latest revision), "Control of External Corrosion on Metallic Buried, Partially
Buried, or Submerged Liquid Storage Systems".
Unless instructed otherwise by the cognizant NAVFAC EFD/EFA OR
USACE DISTRICT, provide an engineering life-cycle cost (LCC) analysis
for the CPS. Coordinate with the NAVFAC EFD/EFA's / USACE
DISTRICT's Corrosion Control Coordinator to establish design efforts and
field test efforts. Obtain preliminary approval from the Corrosion Control
Coordinator prior to accomplishing the LCC analysis. Define the proposed
elements of the LCC analysis and a general description of the proposed
CPS design.
