Clean up of the Site will proceed as an EPA Fund lead action.
2.1.2 Response Actions to Date
Since the issuance of the last POLREP, EPA OSC, EPA ERT, START and ERRS have performed the following activities:
14
March 2013- OSC Tsang, ERT members George Prince and Alan Humphrey and START conduct a
site walk to discuss installation of additional monitoring
wells, collection of soil borings and soil and groundwater samples, and conducting water level measurements from the monitoring wells and from the drainage ditch
adjacent to the Site.
1-2
April 2013- Thompson/Farland Professional Engineers and Land Surveyors (Thompson/Farland) sub-contracted by ERRS was onsite to conduct topographical and elevation surveys. OSC Tsang, the ERRS Response Manager (RM), START, and engineers from Weston Solutions, Inc. conducted a site walk and discussed the scope of work.
16- 17 April 2013 - EPA ERT, START, and the ERRS RM were onsite to conduct a site walk with prospective bidders for installation of four new monitoring wells and repair of three existing monitoring wells.
18 April 2013 - The ERRS RM and Thompson/Farland were onsite to conduct the additional survey of existing surface features and landmarks and install four property boundary markers.
2- 3 May 2013 - ERRS and START were onsite to collect one sample each from the concrete and dirt from pile# 14 for disposal analyses including VOCs, SVOCs, PCBs/pesticides, herbicides, RCRA eight metals and reactivity. Two wipe samples (one for PCBs and the other for PAHs analyses) were collected from pile# 5, 8, 10, 14 and 16. Thompson/Farland was onsite to conduct additional survey activities.
29 May 2013 - EPA ERT, START and ERRS RM conducted a second bid meeting onsite with prospective bidders for installation of four new monitoring wells and repair of three existing wells.
4 June 2013 - ERRS, START and Thompson/Farland were onsite to complete the survey of the access road. OSC Tsang, the ERRS RM and START met with Mr. Lesley Adams, the property owner's representative to discuss the upcoming mobilization and possibility of relocating the three trailers currently located in the area where the support zone would be set up. OSC Tsang, the ERRS RM and the START member also met with the property owner of 45 Walnut Street for access arrangements.
12 June 2013 - ERRS and START conducted a bid walk with prospective bidders for utility clearance and locating service for mapping.
27 June 2013 - START and ERRS RM were onsite to conduct a bid meeting for additional surveying work, which included delineating utility features for utility clearance and locating service contractors, and surveying of additional parcels abutting the Site.
8 - 12 July 2013 - OSC Jarrell, EPA ERT, SERAS, START, and ERRS mobilized to the Site to set up the command post, support zone and decontamination pad. New England Boring Contractors, a well installer subcontracted by ERRS was onsite to install new wells (MW 9, 10, 11 and 12) and repair the existing wells (MW 2, 3, and 7). New wells 9 and 10 were installed on-site and new
wells 10 and 11 were installed off-site on River Rd. All new wells were developed and all existing wells were purged to remove any accumulated
sediment. During the well installation, well 10 appeared to have some hydrocarbon sheen. Five piezometers were installed
and sampled in the ditch on the west side of the Site for VOCs and
SVOCs analyses. Passive diffusion samplers were installed in each piezometer probe for future recovery and analysis for VOCs. The five probes, 30 inches
long with a 12-inch screen, were left in place and will be used for resampling at a later
date under different water level conditions. Soil samples collected from soil borings were sent to EPA New England Regional Laboratory (NERL) for VOCs, SVOCs, RCRA eight metals and PCBs analyses. Based on field collected water quality parameters and water levels, several of the
locations appear to be ground water discharging to surface water, so porewater sampling would be conducted as an indicator of possible ground water discharge
of any site contaminants. On 8 July, Amy Vaillancourt of Tighe and Bond, a consultant for the City of Middletown, stopped by the Site and met with EPA ERT for a site update.
15 - 19 July 2013 - OSC Tsang, START, and ERRS were onsite to conduct decontamination and relocation of antique vehicles. START conducted groundwater sampling on all of the wells. On 17 July, Amy Vaillancourt of Tighe and Bond stopped by the Site and met with OSC Tsang for a site update.
2.1.3. Enforcement Activities, Identity of Potentially Responsible Parties (PRPs)
The Settlement Agreement between EPA, City of Middletown and RLO Properties, Inc. became effective on 20 August 2012. On 23 August 2012, the City of Middletown submitted a $2.8 Million settlement payment to EPA under the terms of the Agreement.
