Football Field Complex Remedy Project Overview
The project involves remedial measures for the football field complex at Elmira High School, focusing on soil removal, groundwater monitoring, and vapor intrusion prevention. Excavation, disposal of hazardous waste, and construction of institutional controls are key components. Plans for interim remedial measures (IRM) include excavation volumes and waste disposal details, aimed at preventing contamination exposure and ensuring safety on-site. The project addresses the detection of pollutants in soils and groundwater, along with the removal of industrial sewers. Construction plans for fall 2020 include IRM #5 submissions to NYSDEC for approval, aiming to proceed with excavation and disposal activities.

IRM 4A & IRM 5: Football Field Complex Remedy Interim Remedial Measure Construction Fall 2020 Former Sperry Remington Site at Elmira High School NYSDEC ID # C808022 Public Availability Session December 2020
Football Field Complex (FFC) Remedial Strategy Proposed Remedy Interim Remedial Measure (IRM) Fall 2020 Soil Removal and Off-Site Disposal Prevent potential exposure to contamination in surface and shallow soils Excavation of subsurface soils above Site Cleanup Standards Former Industrial Sewer Removal Cover System Construction Institutional Controls (to prevent exposure to soil, groundwater and soil vapor) Site Management Plan Groundwater Use Restrictions Prevent potential exposure & use of groundwater Cover System Maintenance Prevent potential exposure to contamination remaining in underlying soils Vapor Intrusion Evaluation (Future Construction) Prevent potential exposure via vapor intrusion Groundwater Monitoring FFC Pre-Design Investigation Summary (July 2018 September 2020) Detection of PCBs, metals, PAHs and VOCs in shallow soils above screening criteria Detection of PCBs, metals, PAHs and VOCs in soils above screening criteria for protection of groundwater Detections of PCBs above hazardous waste criteria in soil Detection of PCBs, metals and VOCs in on-site groundwater in areas with no buildings Characterize extent, integrity and contents of former industrial sewer and detections of PCBs above hazardous waste criteria in sewer contents. No evidence of release to surrounding soils

Community Air Monitoring Ambient Air Monitoring Additional monitors upwind and downwind of excavation, stockpiling and loading activities Samples will be collected for PCB analyses when soils with PCBs > 50 mg/kg are handled. Tisch (PCB) air monitoring locations including air intakes on top of EHS building Results will be posted weekly to the NYSDEC web site. Dust (PM10) Monitoring Monitors placed at CAMP locations at the Site perimeter Dust levels measured continuously Readings are available in real- time with telemetry Notifications sent when dust levels exceed action levels Current Data: http://nydec-elmira.s3-website-us-east- 1.amazonaws.com/list.html?prefix=IRM%204A/Air%20Monitoring/
Truck Routes for Off-Site Disposal Trucks will enter and exit the Site between the hours of 7:00 AM and 5:00 PM except during student arrival (7:45 8:30 AM) and departure (2:30 3:15 PM) when school is in session. No truck traffic will occur outside those hours without prior notification of NYSDEC.
IRM Construction Protecting Workers, the Community and the Environment Worker Safety Community Safety Environmental Protection Dust control during excavation, stockpiling and loading of soil All equipment is decontaminated before leaving the site Silt fence to prevent runoff from disturbed areas Personal Protective Equipment (PPE): Hard hat Steel-toed boots Safety glasses Gloves High-viz clothing Training Excavated soil is covered prior to proper disposal Traffic control on/off S Main Street Storm sewers protected from debris during construction
Covid-19 Precautions Site activities are Essential Services Covid-19 Response Plans have been prepared and NYS guidance for Essential Workers is followed Site workers use of appropriate testing, face coverings, temperature checks, sanitary measures & social distancing
