DRAFT Ver. 1-C-doc-4-5-10 Page 15 Tier II Qualified Facility SPCC Plan Table G-18 General Rule Requirements for Onshore Facilities N/A Buried Tanks For completely buried metallic tanks installed on or after January 10, 1974 at this facility:[§112.8(c)(4) and 112.12(c)(4)] x Tanks have corrosion protection with coatings or cathodic protection compatible with local soil conditions. x Regular leak testing is conducted. For partially buried or bunkered metallic tanks [§112.8(c)(5) and §112.12(c)(5)]: x Tanks have corrosion protection with coatings or cathodic protection compatible with local soil conditions. Bulk Container Inspection and Testing Each aboveground bulk container is tested or inspected for integrity on a regular schedule and whenever material repairs are made. Records of testing and inspection are kept – including comparison records. Scope and frequency of the inspections and inspector qualifications are in accordance with industry standards.[See Inspection Log and Schedule and Bulk Storage Container Inspection Schedule in Attachments 3.1 and 3.2][§112.8(c)(6) and §112.12(c)(6)(i)] Outsides of bulk storage containers are frequently inspected for signs of deterioration, discharges, or accumulation of oil inside diked areas. Container supports and foundations are regularly inspected.[See Inspection Log and Schedule in Attachment 3.1][§§112.8(c)(6) and 112.12(c)(6)] For bulk storage containers that are subject to 21 CFR part 110 which are shop-fabricated, constructed of austenitic stainless steel, elevated and have no external insulation, formal visual inspection is conducted on a regular schedule. Appropriate qualifications for personnel performing tests and inspections are documented.[See Inspection Log and Schedule and Bulk Storage Container Inspection Schedule in Attachments 3.1 and 3.2][§112.12(c)(6)(ii)] Internal Heating Coils The facility will control leakage through defective internal heating coils by monitoring the steam return and exhaust lines for contamination from internal heating coils that discharge into an open watercourse, or passing the steam return or exhaust lines through a settling tank, skimmer, or other separation or retention system.[§112.8(c)(7)] Overfill Prevention and Container Engineering Each container installation has been engineered or updated in accordance with good engineering practice to avoid discharges.[§112.8(c)(8)] For each bulk container or container installation, at least one of the following devices is provided: [§112.8(c)(8)(i– iv))] x High liquid level alarms with an audible or visual signal at a constantly attended operation or surveillance station. In smaller facilities an audible air vent may suffice. x High liquid level pump cutoff devices set to stop flow at a predetermined container content level. x Direct audible or code signal communication between the container gauger and the pumping station. x A fast response system for determining the liquid level of each bulk storage container such as digital computers, telepulse, or direct vision gauges. If this alternative is used, the facility will ensure a person be present to monitor gauges and the overall filling of bulk storage containers. Liquid level sensing devices are regularly tested to ensure proper operation [See Inspection Log and Schedule in Attachment 3.1].[§112.8(c)(8)(v)] Effluent Treatment Facilities The facility observes on-site effluent treatment facilities frequently enough to detect possible system upsets that could cause a discharge as described in §112.1(b).[§112.8(c)(9)] Visible Discharge Correction Visible discharges which result in a loss of oil from the container, including but not limited to seams, gaskets, piping, pumps, valves, rivets, and bolts are promptly corrected and oil in diked areas is promptly removed.[§§112.8(c)(10) and 112.12(c)(10)] x x x x x x x x x x x x x x x x x
