PART 112--OIL POLLUTION PREVENTION--Table of Contents
 
   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. 112.9  Spill Prevention, Control, and Countermeasure Plan requirements 
for onshore oil production facilities.

    If you are the owner or operator of an onshore production facility, 
you must:
    (a) Meet the general requirements for the Plan listed under 
Sec. 112.7, and the specific discharge prevention and containment 
procedures listed under this section.
    (b) Oil production facility drainage. (1) At tank batteries and 
separation and treating areas where there is a reasonable possibility of 
a discharge as described in Sec. 112.1(b), close and seal at all times 
drains of dikes or drains of equivalent measures required under 
Sec. 112.7(c)(1), except when draining uncontaminated rainwater. Prior 
to drainage, you must inspect the diked area and take action as provided 
in Sec. 112.8(c)(3)(ii), (iii), and (iv). You must remove accumulated 
oil on the rainwater and return it to storage or dispose of it in 
accordance with legally approved methods.
    (2) Inspect at regularly scheduled intervals field drainage systems 
(such as drainage ditches or road ditches), and oil traps, sumps, or 
skimmers, for an accumulation of oil that may have resulted from any 
small discharge. You must promptly remove any accumulations of oil.
    (c) Oil production facility bulk storage containers. (1) Not use a 
container for the storage of oil unless its material and construction 
are compatible with the material stored and the conditions of storage.
    (2) Provide all tank battery, separation, and treating facility 
installations with a secondary means of containment for the entire 
capacity of the largest single container and sufficient freeboard to 
contain precipitation. You must safely confine drainage from undiked 
areas in a catchment basin or holding pond.
    (3) Periodically and upon a regular schedule visually inspect each 
container of oil for deterioration and maintenance needs, including the 
foundation and support of each container that is on or above the surface 
of the ground.
    (4) Engineer or update new and old tank battery installations in 
accordance with good engineering practice to prevent discharges. You 
must provide at least one of the following:
    (i) Container capacity adequate to assure that a container will not 
overfill if a pumper/gauger is delayed in making regularly scheduled 
rounds.
    (ii) Overflow equalizing lines between containers so that a full 
container can overflow to an adjacent container.
    (iii) Vacuum protection adequate to prevent container collapse 
during a pipeline run or other transfer of oil from the container.
    (iv) High level sensors to generate and transmit an alarm signal to 
the computer where the facility is subject to a computer production 
control system.
    (d) Facility transfer operations, oil production facility. (1) 
Periodically and upon a regular schedule inspect all aboveground valves 
and piping associated with transfer operations for the general condition 
of flange joints, valve glands and bodies, drip pans, pipe supports, 
pumping well polish rod stuffing boxes, bleeder and gauge valves, and 
other such items.
    (2) Inspect saltwater (oil field brine) disposal facilities often, 
particularly following a sudden change in atmospheric temperature, to 
detect possible system upsets capable of causing a discharge.

    (3) Have a program of flowline maintenance to prevent discharges 
from each flowline.
