Air samples were collected over a 24-hour period. Start date is given. 2. Analytical reports (P and P ) were provided by the laboratory, ALS Environmental. Samples were analyzed by U.S. EPA method TO-10A. 3. DVRs (32119: EPA Level IV, Pre-BMP and 32203: EPA Level III, Post-BMP) were provided by LDC. In DVR 32119, %R for the second source standard mixture was slightly higher than the % QC limits, affecting Aroclor 1016, 1221, and 1232 (UJ qualified). In DVR 32203, all samples were UJ qualifed due to no continuing calibration performed, affecting only Aroclors 1016, 1221, 1232, 1242, and Also in DVR 32203, %R for second source standard mixtures were slightly higher than the QC limits of85-115%, affecting only Aroclors 1016, 1221, and 1232, which were not detected (UJ qualified). 4. If no Aroclors were detected, total PCBs were assumed to be less than (<) the highest 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 primary 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.

µg/100cm 2 Notes: 1. Analytical reports ( , , and ) were provided by the laboratory, ALS Environmental. Samples were analyzed by U.S. EPA method SW Sample area was 100 cm 2 except for 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. 2. DVRs (32128: Pre-BMP, 32121C: Post-BMP, and 32205: Post-BMP Recleaning, - EPA Level IV) were provided by LDC. In DVR 32128, %R for LCS/D was slightly lower than the QC limits of 75% %, affecting Aroclor 1016, 1221, and 1232, which were not detected (UJ qualified); however, Aroclor 1242 in one sample was J qualified due to RPD between two GC columns > 40%. In DVR 32121C, one sample was J qualified for Aroclor 1254, also due to RPD > 40%. 3. Yellow colored cells and bold font indicate total PCB concentration was greater than U.S. EPA's comparison threshold of 1 µg/100 cm Duplicate samples were collected adjacent to the primary sample. Replicate samples were collected in the same location as the primary sample, after the primary sample was collected. 5.
