Aboveground storage
tanks are only required to be registered with
NCDENR – UST Section, if they meet the definition of an Oil Terminal
Facility.
AST Construction
Standards
Aboveground storage tank construction standards are
addressed in the
North Carolina Building Code, Chapter 22 of the North Carolina Fire
Code and the National Fire Protection Association Standard 30 and 30A
(NFPA 30 and NFPA 30A). Currently, no DENR environmental regulations
exist for installation, construction, permitting or monitoring of ASTs.
Questions regarding AST construction standards should
be directed to
the local and/or county fire prevention departments where the AST is
being installed. A list of these fire prevention departments can be
found here:
The North Carolina Department of Insurance – Office of
State Fire
Marshal may also be contacted for questions at (919) 661-5880.

directed to the Division of Air Quality at (919) 715-6274.

Federal Requirements
for
Prevention of Oil Pollution
EPA's Oil Pollution Prevention regulation (40 CFR Part
112) establishes
requirements for facilities to prevent oil spills from reaching the
navigable waters of the U.S. or adjoining shorelines. The rule applies
to owners or operators of certain facilities that drill, produce,
gather, store, process, refine, transfer, distribute, use, or consume
oil.
The regulation applies to non-transportation-related
facilities with a
total aboveground (i.e., not completely buried) oil storage capacity of
greater than 1,320 gallons, or total completely buried oil storage
capacity greater than 42,000 gallons. The regulations apply
specifically to a facility's storage capacity, regardless of whether
the tank(s) is completely filled. In addition to the storage capacity
criteria, a facility is regulated if a discharge or release of oil from
the facility could enter navigable waters of the U.S. or adjoining
shorelines.
The regulation requires that all regulated facilities
have a fully
prepared and implemented Spill Prevention, Control, and Countermeasure,
or SPCC Plan. More information on EPA’s Oil Pollution Prevention
regulations and SPCC plans can be found here: or through EPA Region IV
in Atlanta, Georgia at (404) 562-8761.
