0 0 entering the subsurface environment. The spill container shall meet the following requirements: (A) If it is made of metal, the exterior wall shall be protected from galvanic corrosion. (B) It shall have a minimum capacity of five gallons (19 liters). (C) It shall have a drain valve which allows drainage of the collected spill into the primary container or provide a means to keep the spill container empty. 4 During the May 24, 2004, routine UST inspection at West Lane, all threes ill containers failed to have a minimum capacity f five gallons. During the September 1 , 2005, routine UST inspection at Wilson , the - and 91- octane spill containers failed to hold five gallons for one hour. 4 During the September 20, 2006, routine UST inspection at West Lane, the diesel spill container failed to hold five gallons for one hour. During the October 8, 2007, routine UST inspection at West Lane, the 7-octane spill container failed to hold five gallons for one hour. During the October 18, 2007, routine UST inspection at Charter Way, all three spill containers failed to hold five gallons for one hour. During the March 3, 2008, monitoring system certification inspection at Wilson Way, the 7- and 1-octane spill containers failed to hold five gallons for one hour. Title 23, CCR 2635 ( )( ) Overfill prevention system. The overfill prevention system shall not allow for manual override and shall meet one of the following requirements: (A) Alert the transfer operator when the tank is 90 percent full by restricting the flow into the tank or triggering an audible and visual alarm; or ( ) Restrict delivery of flow to the tank at least 30 minutes before the tank overfills, provided the restriction occurs when the tank is filled to no more than 95 percent of capacity; and activate an audible alarm at least five minutes before the tank overfills; or (C) Provide positive shut-off of flow to the tank when the tank is filled to no more than 95 percent of capacity; or, ( ) Provide positive shut-off of flow to the tank so that none of the fittings located on the top of the tank are exposed to product due to overfilling. During the September 1 , 2005, routine UST inspection at Wilson Way, the facility did not have an overfill prevention system that met the above requirements. Title 23, CCR 2636 (c)(1) All releases in secondary piping to collection sump. Primary piping in contact with hazardous substances under normal operating conditions shall be installed inside a secondary containment system which may be a secondary pipe, vault, or a lined trench. All secondary containment systems shall be sloped so that all releases will flow to a collection sump located at the low point of the underground piping. During the November 16, 2006, monitoring system certification inspection at Wilson Way, secondary containment test boots were found attached in the 7- and 91-octane piping sumps, whichwould have prevented any releases into the secondary containment from loin into a collection sump. Title 23, CCR 2636 ( ( ) Line leak detectors are installed and operational. Automatic line leak detectors shall be installed on underground pressurized piping and shall be capable of detecting a 3-gallon per hour leak rate at 10 psi within 1 hour with a probability of detection of at least 95 percent and a probability of false alarm no greater than 5 percent, and shall restrict or shut off the flow of product through the piping when a leak is detected. 4 The diesel line leak detector at Charter Way was tested and failed on September 20, 2005, and was not replaced and retested until November 23, 2005. 25
