I � � 4. Using field measurements (PID readings, visual appearance and olfactory indications), determine if a release has occurred. 5. If there has been a release, report the release to Illinois Emergency Management Agency(IEMA) and obtain an incident number. In addition to reporting the release, preparation and submission of the 20-day and 45-day reports in accordance with applicable regulations under the Illinois EPA Leaking Underground Storage Tank(LUST) Program. Task 3 —Field Activities for Site Investigation If a release is identified under Task 2, expedited turnaround times for laboratory analytical results will be requested. Far the purposes of this Project and the Site Investigation Work Plan submitted under Task l, it is assumed a release is identified at the Site. Therefore, Task 3 activities to determine the nature and extent, horizontal and vertical, can be implemented without submission of additional documents under the Illinois EPA SRP Program or an amendment to the Brownfield Grant. The field activities identified in the Site Investigation Work Plan will include the use of a Direct Push Technology (DPT) rig to obtain soil samples to a depth of approximately twenty(20) feet below ground surface (fbgs). For the project estimates, a systematic investigation approach utilizing a sampling grid of 20 feet by 20 feet will be used over the property unless there are specific locations identified from the historical records reviews and interviews. If specific locations are identified, Bodine may also use a backhoe to excavate test pits to identify anomalies, lithology, preferential migration pathways and locations of the source(s) of contamination and contaminants of concern. As indicated, it is likely that this approach will be modified into a stratified random approach to incorporate the exact locations of the USTs. From initial assessments of the property for the grant application, the likely contaminants of concern are Benzene, Toluene, Ethylbenzene and Xylenes (total) (BTEX), Lead and Polycyclic Aromatic Hydrocarbons (PAHs), if diesel fuel is indicated in any of the USTs. Since a Comprehensive NFR is being sought, four(4) borings will be used to collect two (2) soil samples from each boring for the Target Compound List (TCL) and Target Analyte List (TAL) under 35 IAC 740. This will result in eight (8) soils samples far TAL/TCL. Sample collection and analysis will be performed in accordance with the procedures outlined in the Illinois EPA approved Site Investigation Work Plan and will include analysis by SW 846 Method 5035/8260B for Volatile Organic Compounds (VOCs), SW 846 Method 6010/6020 for metals (total), SW 846 Method 1311 for metals, Synthetic Precipitation Leaching Procedure (SPLP), SW 846 Method 8310C for PAHs and SW 846 Method 8270 for Semi-Volatile Compounds (SVOCs). The laboratory selected will be an Illinois EPA and NELAC certified laboratory.
