Clearwater Oil Company, Ltd.

Big Bear Lease No. 2 Production Facility

SAMPLE Spill Prevention, Control, and

Countermeasure (SPCC) Plan

3.4.5Flowline Maintenance Program [112.9(d)(3)]

Because the facility is relying on a contingency plan to address discharges, the flowline maintenance program is specifically implemented to maintain the integrity of the primary container (in this case piping) to minimize releases of oil from this part of the production facility. The facility’s gathering lines and flowlines are configured, inspected monthly for leaks at connections and on each joint, corrosion (pitting, flaking), and maintained to minimize the potential for a discharge as summarized in Table 3-6. Records of integrity inspections, leak tests, and part replacements are kept at the facility for at least three years (integrity test results are kept for ten years).

Table 3-6: Components of flowline maintenance program





Well pumps are equipped with low-pressure shut-off systems that detect pressure drops and minimize spill volume in the event of a flowline leak.

Flowlines are identified on facility maps and are marked in the field to facilitate access and inspection by facility personnel. Flowline maps and field tags indicate the location of shutdown devices and valves that may be used to isolate portions of the flowline.

With the exception of a portion of Flowline B under an access road, the flowlines and appurtenances (valves, flange joints, supports) can be visually observed for signs of leakage, deterioration, or other damage.



Lines are visually inspected for leaks and corrosion as part of the monthly rounds by field personnel, as discussed in Section 3.4 above.


The buried portions of Flowline B are coated/wrapped and visually observed for damage or coating condition whenever they are repaired, replaced, or otherwise exposed.

Every five years, flowlines are tested using ultrasonic techniques to determine remaining wall thickness and mechanical integrity. Copies of test results are maintained at the facility for ten years to allow comparison of successive tests.



Any leak in the flowline or appurtenances is promptly addressed by isolating the damaged portion and repairing or replacing the faulty piece of equipment. Clearwater does not accept pipe clamps and screw-in plugs as forms of repair.

Any portion of a flowline that fails the mechanical integrity test is repaired and retested, or replaced.

3.5 Personnel, Training, and Discharge Prevention Procedures [112.7(f)]

The Field Operations Manager has been designated as the point of contact for all oil discharge prevention and response at this facility.

All Clearwater field personnel receive training on proper handling of oil products and procedures to respond to an oil discharge prior to entering any Clearwater production facility. The training ensures that all facility personnel understand the procedures described in this SPCC Plan and
