SECTION 1 - GENERAL

This Contract Task Order (CTO) is for performing Long-Term Environmental Operations, Maintenance and Monitoring (OM&M) of the Site 1 and Site 4 Remediation Systems, Naval Weapons Industrial Reserve Plant (NWIRP), Bethpage, New York. The duration of work under this CTO shall not exceed 24 months from the award date. The Department of the Navy (Navy) Naval Facilities Engineering Command (NAVFAC) Mid-Atlantic (Midlant) will administer this contract and will manage the Work Elements under this CTO. All requirements of the Basic Contract, in addition to those specifically mentioned in this CTO, remain in full effect and performance under this CTO shall be in accordance therewith.

The task order modification will be for 12 months of operation from 01 April 2025 to 31 March 2026. A firm-fixed price shall be provided for the 12-month period. If there are changes to the scope of work over the course of the task order term, a modification proposal will be requested, and once negotiated; the changes will be incorporated into the task order by bilateral agreement.

1.1. Performance Objective (s):

The contractor will conduct 12-months of long-term environmental Operations, Maintenance & Monitoring of the Site 1 SVE System and Cap and conduct groundwater monitoring and 12 months of the Site 4 Biosparge system at Installation Restoration (IR) Site 4 – Former Underground Storage Tanks in accordance with the OM&M Manual and Supplemental Monitoring Plans previously prepared. At the completion of the operation, maintenance and monitoring, tasks, the contractor will submit a final report. The contractor shall follow the previous report format. The contractor shall work with NWIRP, Bethpage and the State regulators to complete this work.

1.2. Background:

Site 1 As a part of the CERCLA remedial actions at IR Site 1 – Former Drum Marshalling Area at NWIRP Bethpage, New York, a SVECS was constructed. Chlorinated solvents including trichloroethene (TCE), tetrachloroethene (PCE), and 1,1,1-trichloroethane (TCA) have been identified as the VOCs of interest in soil gas at the site. Concentrations greater than 1,000 µg/m3 (micrograms per cubic meter of soil vapor) have been directly associated with Site 1 activities and historical environmental data, and based on preliminary screening, exceed guidelines established by the New York State Department of Health (NYDOH) for sub-slab soil vapor concentrations. Of these chemicals, TCE is the primary VOC of concern. Addressing TCE contamination in accordance with DOH guidance should address the other VOCs associated with the site

(NYSDOH, 2006).

PCBs, cadmium, and chromium have also been identified in site soils at concentrations requiring remediation. The majority of these chemicals have been detected in the central portion of Site 1.

Based on limited data, these chemicals are not expected to be present along the fence line at environmentally significant concentrations (i.e., trigger handling as hazardous waste).

Construction was completed in 2009 by Tetra Tech, EC who had also been tasked with operation and maintenance of the system for an initial period of 6 months (January – July 2010). The system was constructed to capture contaminated soil vapor with a TCE concentration greater than 250 µg /m3. A secondary objective of this project is to address soil vapor with a TCE concentration greater than 5 µg /m3 (Design Analysis Report for Soil Vapor Extraction Containment System, TtNUS, April 2009). The SVECS was designed for a 4 year operational life;

however, soil vapor concentration still exceed the 250 µg /m3 for TCE. Six soil vapor extraction (SVE) well (clusters, each consisting of an intermediate and deep well, will be utilized for the extraction of soil vapors during the system operation. The six deep SVE wells are also capable of being used as monitoring wells for collecting groundwater samples. However, at this time, the Navy has determined that collection of groundwater samples will not be required. The six intermediate SVE wells will not encounter groundwater and will only be used for soil vapor extraction. Eighteeen soil vapor pressure monitors (SVPMs) will be used to monitor the effectiveness of the system in capturing and containing the contaminated soil vapors in the area east of Site 1. These SVPM were installed to ensure the offsite vacuum field is maintained and the SVECS continues to function as a mitigation system for the impacted and potentially impacted homes in the neighborhood.

Two manuals were written to address the operation and maintenance of the SVECS – “Final Operations and Maintenance Plan for Soil Vapor Extraction Containment System” and the “Supplemental Offsite Soil Vapor Intrusion Monitoring Plan for the Soil Vapor Extraction Containment System”. These plans were developed to continue SVECS operations until such time when the remediation goals have been met or until the system becomes operationally inefficient.

It is the intention of this statement of work to obtain services for the continued operation and maintenance of the SVECS, and continued monitoring of vapor/air by means of a combination fixed-price and indefinite quantity task order.

Site 4 As a part of the CERCLA remedial actions at IR Site 4 – Former Underground Storage Tanks at NWIRP Bethpage, New York, a steam injection system was constructed. Contaminants of Concern (COCs) identified for groundwater include volatile organic compounds (VOCs) (benzene, ethylbenzene, and total xylenes), semi-VOCs (SVOCs) (naphthalene and pentachlorophenol), and metals (cobalt and manganese). COCs identified for subsurface soil include SVOCs, including benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, chrysene, and naphthalene.

Steam injection began on April 9, 2019 through all six steam injection wells: SI-1S, SI-2S, SI-3S, SI-1D, SI-2D, and SI-3D. The system was operated continuously, with minor interruptions throughout the year. System parameters, including water meter readings, steam injection flowmeter readings, and thermocouple temperature readings at 15 and 20 feet below ground surface were recorded daily beginning May 31, 2019. The results of the steam injection activities are presented in the Technical Memorandum for Operable Unit 3 Site 4 Underground Storage Tanks Steam Injection Operation and Performance Summary Report dated 26 June 2020.

The biosparge system consists of an air compressor, filters, injection manifold, conveyance piping, and 9 injection wells. A manual was written to address the operation and maintenance of the steam injection and biosparge system – “Draft Operations and Maintenance Manual Steam Injection with Free Product Recovery and Biosparging System” this manual is expected to be finalized prior to the start of field activities; operation of the biosparge system is currently based on the Draft O&M Manual. These plans were developed to continue biosparge system operation until such time when the remediation goals have been met or until the system becomes operationally inefficient. It is the intention of this statement of work to obtain services for the continued operation and maintenance of the biosparge system and continued monitoring of groundwater by means of a combination fixed-price and indefinite quantity task order.
