t By February 2007, construction of the Site Improvement Project was substantially complete; however, the vegetation in the evapotranspirative (ET) closure was not well established. At that time, it was assumed that difficulty in growth was due to the failure of the Contractor to include fungus inoculants with the seed, as specified. This project also included a barrier between existing Module "I" refuse and new refuse that can be placed due to the presence of Module 1. At the direction of RWQCB staff, this barrier was an extension of the Module 1 liner with significant effort expended to ensure that the barrier over Module "I" refuse was gas-tight. In November 2007, the ET area was again reseeded, this time with fungus inoculants as specified. In the spring of 2008, it was determined that the seed growth remained insufficient for adequate ET cover. In November 2008, the closure cap soil was amended and fertilized, and again seeded. In the spring of 2009, vegetation was growing healthily on the ET cap area. On March 4, 2009, San Joaquin County staff noticed that the landfill gas (LFG) condensate pump discharge was connected to the secondary leachate sump of Module 1. The level of condensate within the secondary sump pipe was found to be constant, and staff had not observed saturated soil in that area, so County staff concluded that the LFG condensate had been retained within the primary and secondary sump of that Module, and had not been released to the environment. In April 2009 the LFG condensate was removed from the secondary sump, and the soil gas trench (installed beneath the liner of Module 1) was activated to enhance the protection of groundwater. On June 10, 2009 CWRWQCB staff issued a notice of violation for discharge of wastes outside of containment. MONITORING PROGRAM Water quality is monitored in accordance with WDR Order No. R5-2003-0020. Groundwater New wells MW-4 and MW-5 were installed during the fall of 2006. The groundwater well network now consists of upgradient well MW-4 and downgradient wells MW-2R, MW-3, and MW-5. MW-1,which had previously been considered"upgradient" is now known to be crossgradient from the landfill, and not upgradient of either the landfill or another monitoring well. All monitoring wells are equipped with dedicated purge and sampling pumps.
