   Subpart B--Requirements for Petroleum Oils and Non-Petroleum Oils, 
  Except Animal Fats and Oils and Greases, and Fish and Marine Mammal 
 Oils; and Vegetable Oils (Including Oils from Seeds, Nuts, Fruits, and 
                                Kernels)
 
Sec. 112.11  Spill Prevention, Control, and Countermeasure Plan requirements 
for offshore oil drilling, production, or workover facilities.

    If you are the owner or operator of an offshore oil drilling, 
production, or workover facility, you must:
    (a) Meet the general requirements listed under Sec. 112.7, and also 
meet the specific discharge prevention and containment procedures listed 
under this section.
    (b) Use oil drainage collection equipment to prevent and control 
small oil discharges around pumps, glands, valves, flanges, expansion 
joints, hoses, drain lines, separators, treaters, tanks, and associated 
equipment. You must control and direct facility drains toward a central 
collection sump to prevent the facility from having a discharge as 
described in Sec. 112.1(b). Where drains and sumps are not practicable, 
you must remove oil contained in collection equipment as often as 
necessary to prevent overflow.
    (c) For facilities employing a sump system, provide adequately sized 
sump and drains and make available a spare pump to remove liquid from 
the sump and assure that oil does not escape. You must employ a 
regularly scheduled preventive maintenance inspection and testing 
program to assure reliable operation of the liquid removal system and 
pump start-up device. Redundant automatic sump pumps and control devices 
may be required on some installations.
    (d) At facilities with areas where separators and treaters are 
equipped with dump valves which predominantly fail in the closed 
position and where pollution risk is high, specially equip the facility 
to prevent the discharge of oil. You must prevent the discharge of oil 
by:
    (1) Extending the flare line to a diked area if the separator is 
near shore;
    (2) Equipping the separator with a high liquid level sensor that 
will automatically shut in wells producing to the separator; or
    (3) Installing parallel redundant dump valves.
    (e) Equip atmospheric storage or surge containers with high liquid 
level sensing devices that activate an alarm or control the flow, or 
otherwise prevent discharges.
    (f) Equip pressure containers with high and low pressure sensing 
devices that activate an alarm or control the flow.
    (g) Equip containers with suitable corrosion protection.
    (h) Prepare and maintain at the facility a written procedure within 
the Plan for inspecting and testing pollution prevention equipment and 
systems.
    (i) Conduct testing and inspection of the pollution prevention 
equipment and systems at the facility on a scheduled periodic basis, 
commensurate with the complexity, conditions, and circumstances of the 
facility and any other appropriate regulations. You must use simulated 
discharges for testing and inspecting human and equipment pollution 
control and countermeasure systems.
    (j) Describe in detailed records surface and subsurface well shut-in 
valves

and devices in use at the facility for each well sufficiently to 
determine their method of activation or control, such as pressure 
differential, change in fluid or flow conditions, combination of 
pressure and flow, manual or remote control mechanisms.
    (k) Install a BOP assembly and well control system during workover 
operations and before drilling below any casing string. The BOP assembly 
and well control system must be capable of controlling any well-head 
pressure that may be encountered while the BOP assembly and well control 
system are on the well.
    (l) Equip all manifolds (headers) with check valves on individual 
flowlines.
    (m) Equip the flowline with a high pressure sensing device and shut-
in valve at the wellhead if the shut-in well pressure is greater than 
the working pressure of the flowline and manifold valves up to and 
including the header valves. Alternatively you may provide a pressure 
relief system for flowlines.
    (n) Protect all piping appurtenant to the facility from corrosion, 
such as with protective coatings or cathodic protection.
    (o) Adequately protect sub-marine piping appurtenant to the facility 
against environmental stresses and other activities such as fishing 
operations.
    (p) Maintain sub-marine piping appurtenant to the facility in good 
operating condition at all times. You must periodically and according to 
a schedule inspect or test such piping for failures. You must document 
and keep a record of such inspections or tests at the facility.
