REVISED MONITORING AND REPORTING PROGRAM NO. R5-2008-0148 g LAWRENCE LIVERMORE NATIONAL SECURITY, LLC AND THE U.S. DEPARTMENT OF ENERGY FOR LAWRENCE LIVERMORE NATIONAL LABORATORY SITE 300 SAN JOAQUIN AND ALAMEDA COUNTIES PERCOLATION PIT INSPECTIONS 8. The Discharger shall inspect monthly the five mechanical equipment percolation pits located at Buildings 806A, 827 A, C, D, and E. If standing water is visible during the quarterly inspection, the Discharger shall increase the inspection frequency to weekly until no standing water is visible. 9. The Discharger shall inspect monthly the seven cooling tower percolation pits located at Buildings 801, 809, 812, 817A, 826, 827A, and 851. If standing water is visible during the quarterly inspection the Discharger shall increase the inspection frequency to weekly until no standing water is visible. The more frequent inspections are required at percolation pits with standing water in order to prevent overflow of the percolation pits. COOLING TOWER BLOWDOWN EFFLUENT MONITORING 10.The Discharger shall semi-annually collect representative grab samples of blowdown discharges from each active cooling tower for the analytes shown in Table 3. Active cooling towers which discharge to percolation pits are located at Buildings 801 , 809, 817A, 826, 827A, and 851. The cooling tower which discharges to a septic system is located at Building 825,. 11 .The Discharge shall also record the total flow monthly blowdown flow from the cooling towers. MECHANICAL EQUIPMENT DISCHARGE EFFLUENT MONITORING 12.The Discharger shall collect semi-annually representative grab samples of mechanical equipment discharges at Buildings 827 A; C, D, E and 806A for the analytes shown in Table 3. The Discharger shall retrofit the percolation pit discharges to facilitate the collection of composite samples. Starting in the first semester of 2010, the Discharger shall collect semi-annually composite samples of mechanical equipment discharges at Buildings 827 A, C, D, E and 806A for the analytes shown in Table 3. Composite samples shall be representative of the combined discharge to the percolation pit during a day of operation at each specified facility. Table 3.
