TELEVISION. [Provide commercial cable TV or site distribution system(s) when
feasible. Requirements to be edited in accordance with local conditions and availability.] An
antenna system or connection to a TV distribution system shall be provided for each facility.
The TV system shall provide for UHF and VHF reception for color TV. The antenna system may
be either a common antenna serving the entire project (mast or dish), an attic antenna system
for each separate building, or attic antenna for each facility [Edit as required]. The Contractor
shall provide all trenching, conduit, boxes, and backfilling required to install commercial and/or
Contractor provided distribution systems.

CATHODIC PROTECTION. Cathodic Protection (CP) is mandatory on buried
ferrous metallic structures as described below:
4-22.1
Department of Transportation guidance. Shall be as stated in 49 CFR, Part 192,
requires that all metallic natural gas piping be coated and cathodically protected regardless of
the soil resistivity.
4-22.2
Corrosion control. Mandated for all metallic underground storage tanks storing
petroleum or hazardous substance by 40 CFR, Part 280 and AR 200-1 and on hazardous liquid
pipelines (e.g., liquid fuel) by 49 CFR, Part 195.
4-22.3 Design requirements. CP systems must be designed to provide protective potential to
meet the requirements of the National Association of Corrosion Engineers (NACE) Standard
RP-0169, Control of External Corrosion on Underground or Submerged Metallic Piping
Systems, or NACE Standard RP-0185, Control of External Corrosion on Metallic Buried,
Partially Buried, or Submerged Liquid Storage Systems, as appropriate.
4-22.4 Compatibility. New or supplemental CP systems shall be compatible with existing CP
systems and other adjacent structures or components. New systems should be compatible with
existing systems to allow ease of repair and maintenance.
4-22.5 Tracer wire. When plastic pipe is used to extend a steel gas distribution main, an
insulated No. 8 AWG copper wire shall be exothermically welded to the existing steel main and
run the length of the new plastic main. This wire can be used as a locator tracer wire and to
maintain continuity to any future steel gas main extension.
4-22.6 Coatings. CP and protective coatings shall be provided for the following buried and
submerged ferrous metallic structures regardless of soil or water resistivity.
4-22.6.1
Natural gas and propane piping.
4-22.6.2
Liquid fuel piping.
4-22.6.3
Underground fuel storage tanks. Not required for those coated in accordance with
UL1746.
4-22.6.4
Fire protection piping.
4-22.6.5 Ductile or cast iron piping. Required for pressurized piping under floor (slab on
grade) in soil.
4-22.6.6 Conduit piping systems. Required for underground heat distribution and chilled water
piping in ferrous metallic conduit.
