If <br /> Pe P <br /> necessary, a grading permit will be obtained from the City of Lodi for excavating the tanks and <br /> soil. <br /> Notification to EHD and the Lodi Fire Department, will be made 48 hours prior to tank <br /> removal The San Joaquin Valley Unified Pollution Control District will be notified 5 days in <br /> advance of planned tank removal The RWQCB will be notified immediately if groundwater is <br /> encountered. <br /> i <br /> 6.2 PROCEDURES FOR TANK REMOVAL <br /> 1. All residual liquid within each UST will be removed. This waste material will be <br /> properly containenzed and transported as specified in Subsection 5.3 <br /> 2 The surface material and soil above the UST will be carefully removed by means of a <br /> backhoe,jackhammer, shovel or other appropriate equipment. Any visually contaminated <br /> soil will be placed on plastic sheeting and kept separate from non-contaminated soil. A <br /> FID will be used to aid in the segregation of the contaminated soil from the non- <br /> contaminated soil. <br /> 3 The atmosphere within the UST will be checked for flammability and oxygen content <br /> using a combustible gas indicator (CGI) and oxygen meter The tank will be degassed <br /> by adding 3 pounds of dry ice per 100 gallons of tank capacity until readings from the <br /> CGI are below 20 percent of the lower explosive limit. Intermittent monitoring of the <br /> atmosphere within the tank will be completed to ensure the atmosphere is below 20 <br /> percent of the lower explosive limit. <br /> 4 Any remaining soil from above the UST will be moved so the surface of the tank can be <br /> inspected. All vent and fill piping to the tank will be carefully disconnected and <br /> removed. <br /> 5.
