Analytical reports (P , P ) were provided by the laboratory, ALS Environmental. Samples were analyzed by U.S EPA method TO-10A. 2. No concentrations were greater than U.S. EPA's health-based threshold of 200 ng/m If no Aroclors were detected, total PCBs are shown as less than (<) the highest method reporting limit. 4. Duplicate samples were collected adjacent to the primary sample. [a] Air samples were collected over a 24-hour period. Start date is given. [b] Post-BMP air samples for Rooms 500A and 502 were collected August 5, Post-BMP air samples for Rooms 505 and 506 were collected August 6, Outdoor samples were collected on respective days.

In DVR 32278, the %R of amounts in second source standard mixtures were slightly higher than the QC limits (85-115%) affecting only Aroclors 1016, 1221, and 1232 (UJ qualified for nondetects). 4. If no Aroclors were detected, total PCBs were assumed to be equal to less than (<) the method reporting limit. 5. No concentrations were greater than U.S. EPA's health-based threshold of 200 ng/m 3 or 0.2 μg/m Duplicate samples were collected adjacent to the original sample. 7. Field blanks have no associated air volume. Laboratory results for field blanks are reported in units of ng/cartridge with a method reporting limit of 500 ng/cartridge. 8.

Analytical reports ( , , , ) were provided by the laboratory, ALS Environmental. Samples were analyzed by U.S. EPA method SW Sample area was 100 cm 2 except field blanks. Field blanks have no associated surface area. Laboratory results for field blanks are reported in units of µg/sample with a method reporting limit of 0.1 to 0.2 µg/sample. Two surface wipe samples, which were collected on door caulking in Room 506, had method reporting limits of 1.0 μg/100 cm 2 and 10 μg/100 cm 2 due to sample dilutions. 2. DVRs (32470B: Post-BMP Recleaning, 32408B: Post-BMP, 32408C: Post-BMP - Level III validation 32296: Pre-BMP - Level IV validation) were provided by LDC. In DVR 32296, %D for continuing calibration was greater than 20%, affecting only Aroclors 1242, 1248, 1254, and 1260 (UJ qualified for non-detects, J qualified for detects). Also in DVR 32296, one sample was J qualified due to RPD > 40%. In DVR 32408C, %D for continuing calibration was greater than 20%, affecting only Aroclors 1242, 1248, 1254, 1260, 1262, and 1268 in two samples (UJ qualified) and all Aroclors in the remaining samples (UJ qualified for non-detects, J qualified for detects). In DVR 32470B, %D for continuing calibration was slightly greater than 20%, affecting all Aroclors (UJ qualified for non-detects, J qualified for detects). Also in DVR 32470B, one sample was J qualified for only Aroclor 1254 due to RPD > 40%. In DVR 32408B, %D for continuing calibration was greater than 20%, affecting all Aroclors in all samples (UJ qualified). 3. Yellow colored cells and bold font indicate concentrations were greater than U.S. EPA's comparison threshold of 1 µg/100 cm Duplicate samples were collected adjacent to the primary sample.
