Patuxent Research Refuge, Maryland

Shooting Range Lead Abatement

Statement Of Work

March 18, 2021

1.0 Introduction and Overview

Patuxent Research Refuge requires lead maintenance services at the Fort Meade Shooting Ranges, located at 202 Wildlife Loop in Laurel, Maryland. The Contractor shall provide a proposal to perform the work as described in the statement of work (SOW).

2.0 Project Objectives

The objectives for this project are for a Contractor to provide firing range lead maintenance services that will aid in mitigating potential physical, occupational, and environmental hazards associated with high concentrations of lead in the backstop berms at the range. The work performed shall enable the facility to meet compliance with OSHA, US EPA, State, and National Rifle Association (NRA) and National Shooting Sports Foundation (NSSF) recommended firing range environmental Best Management Practices (BMPs). The required scope of work is described below.

3.0 Project Location

The project is located at the Patuxent Research Refuge, Shooting Ranges, 202 Wildlife Loop, Laurel, Maryland.

To arrange a site visit, contact Martin Brockman, Facility Manager, at 301-497-5584. His office is located at 12311 Beech Forest Road, Laurel, Maryland 20708. Email is martin_brockman@fws.gov.

4.0 Project Description

Based on reported range usage at Patuxent, 20 to 40 tons (estimated) of lead may be recovered and recycled from the backstop berms and apron areas. The estimated soil quantities for processing may be adjusted based on site conditions encountered during the course of the work, and shall be confirmed with the facility manager during recycling/ removal operations. The Contractor shall excavate and process soil from the backstop berms until lead reclamation becomes economically infeasible and/or 80-90% of lead bullets and bullet fragments (measured as weight percent) are removed.

The estimated project quantities are as follows, and is for information only to allow the Contractor to provide a project proposal. If the estimated quantities are exceeded during construction activities, and this causes the contractors fee to increase, the facility manager and Contracting Officer shall be notified before further work is undertaken.

5.0 Project Submittals

A. Project submittals shall be provided to the Government for review and approval prior to construction activities. Submittals shall include:

1. A proposed construction schedule

2. the means and methods for lead abatement activities,

3. Applications for MDE stormwater management permits and finalized permits,

4. a draft environmental stewardship plan for comment at 95% completion,

5. manifests or weight tickets from lead reclaimed and marketed for sale

6. confirmation from MDE that compliance / closure of erosion and sediment control permitting is completed,

7. Certification documentation for UXO technician II and III.

6.0 Site Coordination Activities

A. The Contractor shall install erosion control and storm water protection measures such as silt fence, waddles and hay bales to protect work areas, drainage area, and the environment.

B. The Refuge will remove materials such as timbers, scrap piles, material piles, fencing, concrete slabs, asphalt, range equipment, and large debris from the lead-impacted soils area as required to facilitate soil processing.

B. The Contractor and the Refuge Facility Manager and Range Control representative shall conduct a site walk through, and discuss the most efficient location(s) for the staged soil piles and processing area, and equipment access to the work areas.

C. Discovery of any item that appears to be military ordinance shall be cause for immediate suspension of work while UXO clearance activities take place. Work may be resumed after clearance. The contractor shall be permitted to move to an adjacent range to continue work while suspected UXO examination takes place.

7.0 Project Technical Requirements

The technical approach for the firing range lead maintenance consists of the following requirements:

A. Maryland Department of the Environment soil erosion and sediment control permitting compliance. MDE requires an approved plan for any earth disturbance of 5,000 square feet or more and 100 cubic yards or more. The contractor shall complete the required applications secure required permits and comply with permit conditions during the project execution. Detailed information is available here.

B. UXO/ MEC Avoidance Construction support. The possibility of accidental contact with buried MEC will be minimized by continuing to prohibit intrusive activities without appropriate MEC-avoidance construction support. A Dig Permit process and form has been developed (Appendix C, Exhibit C-2) for the PRR-NT for any intrusive activity (such as intrusive construction activities) to notify the proponent of the potential MEC hazards and requirements for intrusive activities. The Dig Permit will have a requirement for MEC-avoidance and/or a minimum of on-call MEC Construction Support for intrusive activities. MEC-avoidance shall be carried out by a UXO Technician II. The UXO Technician II shall meet the qualifications specified in the Department of Defense (DoD) Explosives Safety Board Technical Paper 18 (2016). MEC-avoidance requires that discovered surface MEC must be avoided and their locations noted and reported to Explosive Ordnance Disposal (EOD). Detected subsurface anomalies must not be investigated but shall be marked, when appropriate, and avoided. MEC Construction Support in low probability areas require that a UXO Technician II and a UXO Technician III must be contacted to ensure their availability, advised about the project, and placed “on-call” to assist if suspected MEC are encountered during construction (DoD Explosives Safety Board 2019). The following will be included in the dig permit requirements, “When suspected UXO are discovered, leave them in place, immediately execute a “stop work condition,” evacuate the area, and immediately contact your on-call UXO support.” If UXO support verifies UXO, then EOD dispatch is needed. Refuge Facility manager should be contacted immediately at 240- 374-9350. In addition, BRAC and DOI/USFWS should be contacted (contact information is on the Dig Permit [Appendix C, 24 Exhibit C-2]). The current Special Use Permit policy for research and other land users, such as NSA and the Park Service, states that digging is not permitted on the PRR-NT without MEC-avoidance construction support. If a research project or other range use requires digging, a Dig Permit form will be completed, and the permittee must arrange for MEC-avoidance construction support of the area prior to beginning any digging activities. This policy shall remain in place at PRR-NT as a land use control. The MEC Reporting Form (Appendix C, Exhibit C-1) must be filled out by a refuge representative at the conclusion of the intrusive activities if MEC is discovered.

C. Berm Excavation: Excavate the soil from the operating backstop berms and apron areas.

D. Lead Reclamation: Separate the lead bullets/bullet fragments from the excavated soils.

E. Lead Recycling: Recycle the recovered lead, and provide the Patuxent facility with 50% of the value of the recycled lead as a credit / offset to the final invoice for the contractor’s fees for services.

F. E. Berm Reconstruction: Processed soils may be placed in front of the existing berms which will allow for berm reconstruction to take place on the existing footprint. It is the Refuge’s intention to raise the berms and construct additional backstop construction on the existing berm footprints. The contractor may process all existing berm soil if economically feasible.

8.0 Optional Soil Treatment

A. The Contractor shall also provide a proposal to treat the soil with ECOBOND® (or approved equal) treatment of processed range soils to achieve 5.0 mg/L TCLP concentration for lead prior to reconstruction of the berm to meet USEPA Best Management Practices for Lead at Outdoor Shooting Ranges (USEPA, 2005).

If this option is selected by the Government, the following tasks shall be performed:

1. Lead-Impacted Soil Treatment:

Chemically treat lead fines remaining in screened soil with Enviro-blend ® (or approved equal) to meet US EPA Resource Conservation and Recovery Act (RCRA) hazardous lead Toxicity Characteristic Leaching Procedure (TCLP) of 5.0 mg/L to significantly reduce leachability of lead (Pb) into surface soils and reduce the potential for lead (Pb) infiltration to groundwater as measured by SW-846 Test Method 1312: Synthetic Precipitation Leaching Procedure (SPLP).

2. Treatment Confirmation Sampling:

Following a 12–24 hour post-treatment curing period, take a 5-point composite sample from the treated soil; sample(s) shall be sent to a certified laboratory for TCLP Pb analysis. Provide the TCLP results to the Government for review prior to placing the treated soils in front of the remaining backstop berms.

3. Treatment Level Requirements:

Should sample results indicate a failure to achieve RCRA 5.0 mg/L TCLP Pb, the Contractor shall retreat the soil at no additional cost to the Government.

9.0 Excavation, Screening and Recycling Activities

A. The Contractor shall excavate an estimated depth of 1.0 to-2.0 feet of soil from the backstop berms or deeper, if the concentrations of bullets appear economically feasible to recover at deeper depths.

B. Remove 80% to 90% or more (weight percent) of the lead bullets/bullet fragments greater than 1/4“– 3/8” from the lead impacted range soils, using separation systems to remove lead from soils, based on size and “finish” the separation process using appropriate pneumatic separation units (PSU) to separate the lead from like-size materials based on density.

C. Containerize and securely store the recovered lead for proper shipment.

D. Coordinate and ship the recovered lead to a licensed lead recycler. The Contractor shall provide the facility with a 50% portion of the net value of the recycled lead as a credit/ offset against the contractors fee.

E. Provide the facility with lead transport documentation and the Certificate of Recycling, that the lead materials were properly recycled at a licensed lead recycler.

10.0 Government Furnished Services

The following services will be provided by the Refuge facility as required:

A. Assist the Contractor with information to obtain any approvals and permits required. Permit fees shall be paid by the Contractor.

B. Locate any utilities at the site.

C. Ensure the Contractor has safe access to the shooting range site.

D. Protect or remove constructed assets if required.

F. Remove target stands/systems if required.

G. Replace target stands/systems.

H. Reseeding and vegetation of the site after the construction work is completed.

I. Nearby water sources will be provided by the facility.

J. If any live ammunition is discovered, it will be left on site for the Refuge’s Range Control office to manage. The Contractor shall take care of the spent rounds of ammunition.

11.0 Contractor Qualifications

Contractor experience shall be approved by the Contracting Officer and will be based upon submission of the following information by the Contractor:

Experience: Name and location of a similar project completed by the Contractor, including the name and telephone number of the purchaser of the services.

12.0 Shooting Range Restoration

A. Return screened fines in front of the berm of origin. Rough grade these materials to conform to the original configuration of the shooting range. Soil replaced to the backstop berm will be compacted using construction equipment, to allow ongoing use. Compaction testing is not required. The refuge may request that the soil be placed 10-12’ in front of the existing berms on one or two ranges so that the refuge may proceed with construction to increase the berm height immediately following the lead remediation activities.

B. Replace oversize materials to range at a mutually agreed upon location.

C. Perform general site cleanup, and remove any trash or debris from construction activities.

13.0 Project Safety

The contractor shall be comply with Occupational Safety and Health Administration (OSHA) requirements 29 CFR 1910 and 29CFR 1926 during the performance of the work.

14.0 Period of Performance

From date of award to 9 Months.

15.0 Final Report

A. The Contractor shall provide a range maintenance report to the facility, so proper record keeping can be maintained as recommended by the US EPA, NRA, and National Shooting Sports Foundation (NSSF).
