Ms. Ann Kolato SBI070.400.0002 October 15, 2013 Page 2 approximate deadline for submitting an amended RWP of December 20, 2013. Finally, Hull submitted a letter to the City on August 30, 2013 that outlined additional likely steps forward to further assess and remediate the Site pursuant to the VRP. Given the current status of the Site, the following additional activities are proposed: Task 1 Prepare Various IDEM VRP Documents A Sampling and Analysis Plan (SAP) detailing the locations, sampling methods, and laboratory analyses proposed for the next stages of on- and off -Site soil and groundwater sampling must be prepared and approved by IDEM. The SAP will explain field activities that will be completed in Tasks 2 through 4 immediately below. IDEM has also requested that an updated Health and Safety Plan (HASP) and Quality Assurance Project Plan (QAPP) be submitted for their review and approval. Hull proposes to submit revised versions of the existing SAP and existing QAPP first for IDEM's consideration, then follow with an updated HASP prior to the initiation of field activities. Also, as indicated above, Hull has already prepared the August 1, 2013 letter responding to IDEM's 87 individual comments to the RWP, compiled certain historical laboratory data not previously provided to IDEM, and prepared the additional likely steps forward letter as requested by the City. The effort for this correspondence was not covered under the scope of a previous proposal; therefore charges for preparing these letters, including time to discuss response strategy and draft letters with the City and its outside counsel, are included under this Task. Task 2 Install and Sample On -Site Soil Borings This Task will begin with a Site visit to evaluate the presence and condition of all on- and off -site monitoring wells, as well as to mark boring locations before public utility locators are contacted. As requested by IDEM, and as proposed in Hull's August 1, 2013 letter, additional soil sampling must be completed in the southwest parcel of the Site (near Area 19 where a quench oil pit associated with a heat treatment line in former Building 47, and near Area 21 where discolored soils were encountered during demolition activities), and in the southeast parcel of the Site within the footprint of the former Oliver foundry. Ten soil borings within the former Oliver foundry (to depths of 10' below ground surface (bgs)), five soil borings within the former Oliver foundry (to depths of 25' bgs), three soil borings within Area 19 (to depths of 20' bgs), and one soil boring near Area 21 (to a depth of 20' bgs), are proposed. Costs for this Task include analysis of one surface sample and, as applicable, one subsurface soil sample per soil boring - collected using a direct -push drilling rig — and to be tested for: • up to 23 samples collected at 19 soil borings, including quality assurance /quality control (QA /QC) samples, for Resource Conservation and Recovery Act metals using Method SW 846 6010/7000; • up to eight (8) samples collected at three (3) soil borings, including QA /QC samples, for VOCs using Indiana Modified Method 5035A; • up to 22 samples collected at 18 soil borings, including QA /QC samples, for SVOCs using Method SW846 8270/8270 SIM; and • up to seven (7) samples collected at three (3) soil borings, including QA /QC samples, for PCBs using Method SW846 8081. Soil sampling will be conducted using a direct -push unit. Hull's field representative will screen samples using a photoionization detector (PID). The driller will be required to decontaminate all down -hole equipment between
