• Bypass valve is opened and resealed under responsible supervision ; ❑ NX <br /> • Adequate records of drainage are kept. ( See Dike Drainage Log) ❑ 0 <br /> Field drainage systems and oil traps, sumps, or skimmers are inspected at ❑ Q <br /> regularly scheduled intervals for oil, and accumulations of oil are promptly <br /> removed . ( See Inspection Log and Schedule) ( § 112 . 9(b) (2)) <br /> The containers used at this facility are compatible with materials stored and ❑ Q <br /> conditions of storage . ( § 112 . 9 (c) ( 1 )) <br /> All tank battery, separation, and treating facility installations (except for flow- N <br /> through process vessels) are constructed with a capacity to hold the largest <br /> single container plus additional capacity to contain rainfall . Drainage from <br /> undiked areas is safely confined in a catchment basin or holding pond . <br /> ( § 112 . 9 (c) (2)) <br /> Except for flow-through process vessels, containers that are on or above the ❑ <br /> surface of the ground, including foundations and supports, are visually <br /> inspected for deterioration and maintenance needs on a regular schedule . See <br /> Inspection Log and Schedule) ( § 112 . 9 (c) (3 )) <br /> New and old tank batteries at this facility are engineered/updated in <br /> accordance with good engineering practices to prevent discharges including at <br /> least one of the following : <br /> • Adequate container capacity to prevent overfill if regular ❑ ❑X <br /> pumping/gauging is delayed ; <br /> • Overflow equalizing lines between containers sot that full container ❑ ❑X <br /> can overflow to an adjacent container; <br /> • Vacuum protection to prevent container collapse ; or ❑ M <br /> • High level sensors to generate and transmit an alarm to the computer ❑ N <br /> where the facility is subject to a computer production control system . <br /> ( § 112 . 9 (c) (4) <br /> Flow-through process vessels and associated components : <br /> • Are constructed with a capacity to hold the largest single container ❑ M <br /> plus additional capacity to contain rainfall . Drainage from undiked <br /> areas is safely confined in a catchment basin or holding pond . <br /> ( 112 . 9(c)(2) ; and <br /> • That are on or above the surface of the ground, including foundations ❑ ❑X <br /> and supports , are visually inspected for deterioration and maintenance <br /> needs on a regular schedule . ( See Inspection Log and Schedule) <br /> ( 112 . 9(c)(3 ) ; or <br /> • Visually inspected and/or tested periodically and on a regular schedule ❑ ❑X <br /> for leaks, corrosion, or other conditions that could lead to a discharge <br /> to navigable waters ; and <br /> • Corrective action or repairs are applied to flow-through process ❑ M <br /> vessels and any associated components as indicated by regularly <br /> scheduled visual inspections, tests, or evidence of an oil discharge ; and <br /> • Any accumulations of oil discharges associated with flow-through ❑ <br /> process vessels are promptly removed ; and <br /> • Flow-through process vessels are provided with a secondary means of ❑ M <br /> containment for the entire capacity of the largest single container and <br /> sufficient freeboard to contain precipitation within six months of a <br /> discharge from florAhrough process vessels of more than 1 , 000 U . S . <br /> gallons of oil in a single discharge as described in § 112 . 1 (b) , or a <br /> Chrisp Company <br /> Prepared By William Buckman, Safety Director Page 19 of 31 <br />
