The Diesel North and Diesel South submersible turbine pump (STP) sump 208 sensors on the truck side failed when tested. The continuous monitoring system shall be maintained to detect the entry of the liquid or vapor phase of the hazardous substance stored in the primary containment into the secondary containment and to detect water intrusion into the secondary containment. The 208 sensors were replaced and retested during the inspection. A "UST Retrofit Verification with Inspector Already Onsite" form has been completed and provided to the operator and contractor. This was corrected on site. This is a repeat violation, Class ll. 305 HSC 25290.1(e) VPH monitoring of the interstitial spaces of the UST system is not maintained. Communication in the 87-, 91-, and three diesel -submersible turbine pump (STP) sumps and fill sumps, and communication in the under -dispenser -containments (UDC) of the truck side of the facility as well as vacuum sensor monitoring of the secondary containment piping of the truck side of the facility of the vacuum/pressure/hydrostatic (VPH) system were not tested during the inspection on June 16 and 17, 2016. The interstitial space of the UST shall be maintained, as designed, under constant vacuum such that a breach in the primary or secondary containment is detected before the hazardous substance is released into the environment. Immediately contact a properly licensed, trained, and certified contractor to test communication of the VPH components listed above under inspection by the Environmental Health Department (EHD). Documentation of the S6 diesel STP sensor on the auto side of the facility indicates that the S6 sensor has been going into alarm intermittently. On 6/16/2016, S6 sensor was tested, passed, and closed alarm; however, S6 went into alarm on 6/17/2016. Immediately contact a properly licensed, trained, and certified contractor to repair or replace the sensor under permit and inspection by the EHD. This is a repeat violation, Class II. 316 HSC 25290.1(c3), 25290.2(c3) Secondary containment not constructed to prevent water intrusion (after Jul 2003). Approximately one-quarter cup of water was found in the 91 -product fill sump, approximately one-quarter inch of water was found on the south sloping side of the vent box on the automobile side of the facility and approximately one-half inch of water was found covering the vent box bottom on the truck side of the facility. Approximately one cup of liquid was found in the under dispenser containments (UDCs) for dispensers 13/14B, 16A/17B, 17A/18B and 18A/19. Secondary containment shall be constructed to prevent any liquid intrusion into the system by precipitation, infiltration, surface runoff or seepage. The service technicians removed the liquid during the inspection. Continue to check the 91 -product sump, vent boxes and dispensers for liquid and if found, immediately contact a properly licensed, trained, and certified contractor to address the liquid intrusion into the 91 -product sump, vent boxes and UDCs under permit and inspection of the Environmental Health Department (EHD). This was corrected on site. This is a repeat violation, Class II. Page 6 of 8
