Task 2.2 – Accident Prevention Plan (APP)/Site Safety and Health Plan (SSHP)

The Contractor shall prepare a site-specific health and safety plan that specifies employee training, protective equipment, medical surveillance requirements, standard operating procedures, and a contingency plan. Specific requirements are outlined in below.

Accident Prevention Plan

The Contractor shall prepare an Accident Prevention Plan (APP) specific to the activities being performed. It shall include an Activity Hazard Analysis (AHA) as described below. All work shall be conducted in accordance with the APP, the U.S. Army Corps of Engineers Safety and Health requirements Manual (EM 385-1-1, most recent edition), and all applicable federal, state, and local safety and health requirements. A copy of EM 385-1-1 can be accessed electronically at Headquarters USACE website under publications using the following link:

http://www.usace.army.mil/library/.

The APP shall detail how safety and health will be managed during the project. The APP shall address the requirements of applicable Federal, State and local safety and health laws, rules, and regulations. The Contractor shall comply with Federal Acquisition Regulation Clause No. 52.236- 13 for Accident Prevention, which is added by reference. Special attention shall focus on the requirements of EM 385-1-1, specifically Section 01.A.11 through 01.A.18, Figure 1-2 AHA, and Appendix A, (Minimum Basic Outline for Accident Prevention Plan). The APP shall be developed by a qualified person. The contractor shall be responsible for documenting the qualified person’s credentials. Work shall not proceed until the APP has been reviewed by the Government Designated Authority (GDA) (the USACE New England District Safety Office for this project) and deemed acceptable for use on the project.

As part of the APP the contractor must prepare a Site Safety and Health Plan (SSHP) that that covers the 14 elements identified in EM385-1-1, Section 33.B.02. The SSHP shall be attached to the APP as an appendix. SSHP elements adequately covered elsewhere in the APP need not be duplicated again in the SSHP.

The APP shall coordinate with the Contractor's existing safety and health program. Any portions of the Contractor's overall safety and health program referenced in the APP shall be included in the applicable APP element and made site-specific. The Government considers the Prime Contractor to be the "controlling authority" for safety and health of the subcontractors. Contractors are responsible for informing their subcontractors of the safety provisions under the terms of the contract, the penalties for noncompliance, and inspecting subcontractor operations to ensure that accident prevention responsibilities are being carried out.

The Contractor shall conduct a safety meeting at the project site on the first day of work, whenever a new activity or phase of work begins, and daily during the progress of work. All safety meetings shall be documented using USACE safety meeting form or a similar contractor-prepared form.

Records of the safety briefings shall be submitted to the GDA weekly.

Activity Hazard Analysis

An AHA shall be submitted for each major phase of work. A major phase of work is defined as an operation involving a type of work presenting hazards not experienced in previous operations or where a new subcontractor or work crew is to perform the work. The analysis shall define all activities to be performed, identify the sequence of work, the specific hazards anticipated, and the control measures to be implemented to eliminate or reduce each hazard to an acceptable level.

Work shall not proceed on a phase of work until the AHA has been accepted by the GDA. A preparatory meeting shall be conducted by the contractor to discuss the AHA contents with all engaged in the activity. The preparatory meeting shall be conducted by the prime contractor and shall include all subcontractors and Government on-site representatives. The AHA shall be continuously reviewed and revised to address changing site conditions or operations as appropriate.

Accident Reporting

All accidents and near misses shall be investigated by the Contractor. All work-related recordable injuries, illnesses and property damage accidents (excluding on-the-road vehicle accidents), in which the property damage exceeds $2,000.00, shall be verbally reported to the GDA within 24 hours of the incident. Serious accidents as described in EM 385-1-1 Section 01.D.02 shall be immediately reported to the GDA. ENG Form 3394 shall be completed and submitted to the GDA within five working days of the incident.

The Contractor shall complete the “USACE Contractor Monthly Summary Record of Injuries/Illness and Work Hour Exposure” (for prime and its subcontractors) and forward the completed form to the GDA no later than close of business on the 10th calendar day of the following month. The method of transmission by the prime contractor to the GDA shall be electronically.

5.3 Task 3 – Demolition Area 1 (Demo 1) O&M, System Performance Monitoring

Demo 1 is located north of Pocasset Forestdale Road and south of the Impact Area at Camp Edwards, west of Turpentine Road and east of Frank Perkins Road (see Attachments, Figure 1 – IAGWSP Groundwater Treatment System Locations). Demolition training and explosive ordnance disposal at Demo 1 included the destruction of various types of ordnance using explosive charges.

Seven explosive and propellant compounds [hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), TNT, octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine, 2-amino-4,6-dinitrololuene, 4-amino-2,6-dinitrotoluene, perchlorate, and 2,4-dinitrotoluene] have been consistently detected in groundwater and are identified as the contaminants of concern (COCs) in groundwater for the Demo 1 Groundwater Operable Unit (OU).

The Demo 1 Remedial Action (RA) System consists of four independent treatment systems. The systems are located on Frank Perkins Road, Pew Road, at the JBCC base boundary, and Demo 1 off-base. The Contractor shall be responsible for O&M and performance monitoring of these systems under this task.

The Contractor shall be responsible for executing all O&M activities at the Demo 1 RA treatment systems in accordance with the language outlined in Task 3 and the most recent Demolition Area 1 Environmental and System Performance Monitoring (SPM) Report.

The Frank Perkins Road system is housed in an 11,000-square-foot concrete and metal building installed east of Frank Perkins Road near the junction with Pocasset-Forestdale Road. Groundwater is extracted from two extraction wells. The primary components of the system include ion exchange (IX) – granular activated carbon (GAC) treatment. The treatment train includes two IX resin vessels in parallel, each containing 400 cubic feet of Nitrate Selective IX. These are followed by three vessels in series, each of which contain 20,000 pounds of GAC. The system also includes an influent equalization tank, booster pump, a bag filtration system, a backwash water tank, a backwash pump, and a settling tank. Perchlorate is removed primarily through the vessels containing the IX resin. Once the capacity of the IX resin is reached, the GAC vessels remove the remaining perchlorate until change out of the IX resin occurs. The IX resin is not effective for the removal of explosive compounds. Therefore, the removal of explosives is through the first two GAC vessels in series with the third (guard) GAC vessel available to ensure that all perchlorate and explosives are captured prior to discharge. The treatment system has a total maximum process rate of approximately 500 gpm. The current operating flow rate is 175 gpm. The groundwater is reinjected at two reinjection wells.

The Pew Road treatment system consists of a mobile treatment unit (MTU). Groundwater is extracted from one extraction well. The treatment system consists of six pressure vessels that are arrayed in 3 sequential pairs so that the six-vessel process train is the functional equivalent of three vessels in series.

The first pair of vessels contains IX resin and is the principal treatment stage for perchlorate. The lag (2nd) pair of vessels contains GAC to remove explosives and also perchlorate if there is breakthrough from the IX vessels. Finally, the guard (3rd) pair of vessels contains GAC to provide backup capacity.

This ensures that any breakthrough of contaminants from the lag vessels will be captured prior to effluent discharge. Each IX vessel contains 29 cubic feet of Nitrate Selective IX. Each GAC vessel contains 1,000 pounds of GAC. The treatment system has a total maximum process rate up to 110 gallons per minute (gpm). The current operating flow rate is 105 gpm. Groundwater is reinjected at one reinjection well.

The base boundary treatment system is also a MTU. Groundwater is extracted from one extraction well.

The treatment train consists of a single treatment train of three pressure vessels configured similar to the Pew Road treatment system. The IX vessel contains 35 cubic feet of Nitrate Selective IX. The GAC vessel contains 1,000 pounds of GAC. The treatment system has a total maximum process rate up to 50 gallons per minute (gpm). The current operating flow rate is 65 gpm. The groundwater is reinjected through one reinjection gallery.

An off-base groundwater treatment system was installed in 2016. This leading edge treatment system is designed to pump at a rate of 100 gpm. The treatment system consists of a bag filter, ion exchange vessel, and two granular activated carbon vessels. Each IX vessel contains 58 cubic feet of Nitrate Selective IX. Each GAC vessel contains 3,000 pounds of GAC. The treated groundwater is discharged to a single reinjection gallery.

Task 3.1 – O&M Support – Demo 1 On-Base Systems (Frank Perkins Road and Pew Road Systems)

System and wellfield O&M shall be performed to maintain the treatment systems in the most efficient operational condition and minimize pumping downtime. Monitoring at the treatment systems shall include influent and effluent sampling to demonstrate that the treated water being recharged back into the aquifer through the reinjection wells / reinjection gallery is below the reporting limits for perchlorate and RDX.

Plant visits shall focus on periodic verification of operating parameters, routine and preventative maintenance, media change-out, and responses to unplanned plant shutdown (e.g., power failure).

O&M activities shall also focus on wellfield maintenance, which shall include execution of both a routine and preventative maintenance program for the extraction and reinjection wells / reinjection gallery and piping.

The Contractor shall prepare monthly O&M Reports and submit via upload to the EDMS system with e-mail notification to the USACE.

All O&M activities shall be documented in the project Log Books which shall be maintained at the project field office. The O&M Checklist shall be used to ensure that all required system components are inspected during routine O&M and during media change-out operations. The O&M Checklists shall also note required action items or follow up inspections. The O&M Checklists shall be maintained at each system. An Event Log shall also be maintained at each system to document any downtime, including the reason for the downtime and the duration. All O&M monitoring activities shall be conducted by state-licensed wastewater treatment plant operators.

Table 2 identifies specific O&M activities and their anticipated frequency of completion.

The Contractor shall be responsible for the change-out of treatment media (GAC, IX resin, and bag filters). New media shall be inspected upon receipt to ensure the project specifications are met.

While media vessels are empty, the Contractor shall conduct inspections of the interior of the vessels to validate the integrity of the vessels and document the condition of the interior piping and appurtenances. The results of this inspection shall be documented in the project logbooks and in the O&M Checklist.

Spent media shall be transported off-site for re-generation or disposal at an approved facility.

Waste profiles shall be established, in advance, for each of the media. This expedites the media change-out process and ensures minimal downtime for the treatment units. The spent media shall be shipped off-site as a non-hazardous waste using either a Bill of Lading or a non-hazardous waste manifest. The shipping papers will be signed by the Camp Edwards Environmental Manager, Matt McKay, as the Generator of the waste. The USACE will coordinate with Mr. McKay to obtain his signature on the shipping papers.

System optimization of the treatment systems is an ongoing activity and includes various strategies to improve the efficiency of the systems and reduce energy costs. Optimization strategies include the items listed below.

Adjustments to the VFDs to provide the most efficient flow rates and still achieve remedial objectives.

Recommendations for the reduction in sampling frequency or system sample locations, based on observed influent contaminant levels.

Monitor pump amperages to determine pump efficiencies and make recommendations for more energy efficient operations.

Review of pump sequencing and piping systems to minimize redundancy (i.e., turn off effluent pumps and allow the system to discharge on gravity flow).

Temperature monitoring of vaults to determine the need for heat trace during cold weather periods.

System optimization is a dynamic process, and is a direct result of the Contractor’s observations of the system operational status. Expanded optimization strategies shall be evaluated on an on-going basis throughout execution of the task order.

The Contractor shall perform all in-plant monitoring in accordance with the Final Demolition Area 1 Environmental and System Performance Monitoring Report. Change out of expired IX media shall be initiated when perchlorate is detected at a concentration above 0.35 μg/L. Change out of expired GAC media shall be initiated after RDX is detected at a concentration above 0.25 μg/L.

The Contractor shall assume one system carbon and one system IX change-out during the period of performance. The Contractor shall assume the replacement of five well pumps, five pump motors, and four VFDs during the period of performance. The Contractor shall make programming changes to batch flow at a higher flowrate through the Frank Perkins Road system.

Task 3.2 – O&M Support – Demo 1 Off-Base System (Leading Edge System)

The Leading Edge System for Demo 1 is also an MTU. Groundwater is extracted from one extraction well. The treatment train consists of a single treatment train of three pressure vessels configured similar to the Pew Road treatment system. The IX vessel contains 58 cubic feet of

Nitrate Selective IX. The GAC vessel contains 3,000 pounds of GAC. The treatment system has a total maximum process rate up to 100 gallons per minute (gpm).

System and wellfield O&M shall be performed to maintain the treatment systems in the most efficient operational condition and minimize pumping downtime. Monitoring at the treatment systems shall include influent and effluent sampling to demonstrate that the treated water being recharged back into the aquifer through the reinjection wells / reinjection gallery is below the reporting limits for perchlorate and RDX.

O&M activities shall also focus on wellfield maintenance, which shall include execution of both a routine and preventative maintenance program for the extraction and reinjection wells / reinjection gallery and piping.

All O&M activities shall be documented in the project Log Books which shall be maintained at the project field office. The O&M Checklist shall be used to ensure that all required system components are inspected during routine O&M and during media change-out operations. The O&M Checklists shall also note required action items or follow up inspections. The O&M Checklists shall be maintained at each system. An Event Log shall also be maintained at each system to document any downtime, including the reason for the downtime and the duration. All O&M monitoring activities shall be conducted by state-licensed wastewater treatment plant operators.

5.4 Task 4.0 – J-1 Range South O&M, System Performance Monitoring

The J-1 Range is located adjacent to and southeast of the Impact Area, and is one of the ranges formerly utilized by military contractors for testing and development of various weapons and systems, and by the military for training purposes (see Attachments, Figure 1). The J-1 South groundwater plume consists primarily of RDX and octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX), and is believed to have originated in the southeast portion of the J-1 Range. The plume migrates in a southeasterly direction away from the southern end of the J-1 Range.

The objective for the J-1 South Rapid Response Action (RRA) is to mitigate further migration of the plume by capturing and treating contaminated groundwater at the base boundary until the entire plume extent is determined. The J-1 Range South treatment system includes:

two extraction wells (J1SEW0001 and J1SEW0002) located at the base boundary near existing monitoring well cluster MW-398, operating at 125 gallons gpm;

one MTU; and one infiltration trench to return treated groundwater to the aquifer.

There are two parallel treatment trains of three GAC vessels each, the first two serving as lead RDX removal vessels and the last acting as a polishing step. After passing through the GAC-GAC-GAC train, the treated water is reintroduced to the groundwater through an infiltration trench. This trench is located along the base boundary southwest of the proposed extraction well. The system O&M requirements are outlined in the Final SPM Plan for the J-1 South.

The Contractor shall be responsible for executing all O&M activities at the J-1 South RRA system in accordance with the language outlined in Task 4 and the most recent Final J-1 South Rapid Response Action System Performance Monitoring Plan.
