PART 112_OIL POLLUTION PREVENTION--Table of Contents

 

 Subpart C_Requirements for Animal Fats and Oils and Greases, and Fish 

  and Marine Mammal Oils; and for Vegetable Oils, including Oils from 

                    Seeds, Nuts, Fruits, and Kernels.

 

Sec.  112.15  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 that 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.
