PERFORMANCE-BASED WORK STATEMENT

I. GENERAL INFORMATION

A. Services, non-personal, to provide all equipment, labor, travel, and materials (unless otherwise provided herein) necessary for a service agreement for on-site surveying and decommissioning of the Reston Radiochemistry Laboratory (1B307, 1B307A, 1B307B, 1B307C) and Inorganic

Geochemistry Laboratory (1B309), John Wesley Powell Federal Building, Water Mission Area, mailto:ndemby@usgs.gov

140G0123Q0208

Document Title

Project Laboratories Branch, Reston, VA 20192 (Figure 1). The contractor shall perform all activities in accordance with all Federal, state, and local laws, statutes, regulations, and codes.

B. The Reston Radiochemistry Laboratory and Inorganic Geochemistry Laboratory processed and analyzed various radiological isotopes in the John Wesley Powell Federal

Building (JWPFB). The USGS is required to clean all areas where radiological materials were used or stored before returning the laboratories back to general use. These laboratories are being remodeled and repurposed for other than radiological uses and shall be surveyed in accordance with the Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) decommissioning surveys. MARSSIM was developed to ensure surveys are conducted with the proper rigor, quality assurance, and statistical analysis to make proper decisions.

The working hypothesis of MARSSIM is that all impacted areas being evaluated for release have a reasonable potential for radioactive contamination above the derived concentration guideline levels (DCGL). This initial assumption means that all areas are initially considered Class 1 areas unless some basis for reclassification as non-impacted, Class 3, or

Class 2 is provided.

• Class 1 areas are areas that have, or had prior to remediation, a potential for radioactive contamination (based on site operating history) or known contamination (based on previous radiological surveys).

• Class 2 areas are areas that have, or had prior to remediation, a potential for radioactive contamination or known contamination, but are not expected to exceed the DCGLw.

• Class 3 areas are any impacted areas that are not expected to contain any residual radioactivity or are expected to contain levels of residual radioactivity at a small fraction of the DCGLw, based on site operating history and previous radiological surveys.

Per the USGS Radioisotope license 05-01399-08, Attachment 10.6b REV 2, the following

Guidelines for Deactivating a Radioisotope Utilization Permit shall be followed.

For areas to be released to unrestricted use, contaminated facilities and equipment must be disposed of as radioactive waste, transferred to another authorized storage/use location, or decontaminated to unrestricted release levels in accordance with the guidance in

Consolidated Decommissioning Guidance: Decommissioning Process for Materials

Licensees (NUREG-1757, Volume 1, Revision 2) Appendix B Screening Values. If necessary, site-specific screening values will be developed in accordance with NRC guidance and approved by the NRC prior to release.

The Reston Radiochemistry Laboratory (1B307, 1B307A, 1B307B, 1B307C) and

Inorganic.

Geochemistry Laboratory (1B309) are known to have contained or used radiological materials and shall be surveyed as the appropriate survey units based on historical records

(See Figure 5). The rationale for selecting the survey units shall be developed using the

Data Quality Objectives Process and be fully documented (MARSSIM Section 4.6).

Known Radiological Contaminants of Concern include:

These materials comprise all of the known radioactive materials used in the labs. The isotopes used possessed low to moderate activity levels. Radioactive material use in each room was location specific, but the entire room(s) shall be surveyed.

Locations associated with radiation use:

In relation to Water Mission Area research activities at the JWPFB, there are five (5) locations where radioisotopes were either used, analyzed, or stored. Such use was restricted to the Reston Radiochemistry Laboratory (1B307, 1B307A, 1B307B and 1B307C) and the

Inorganic Geochemistry Laboratory (1B309) where weighing of isotope-bearing materials occurred. Based on historical knowledge, only minor sample handling spills of low-level radioactive materials occurred in these rooms. All such spills were immediately cleaned up.

All test swipes for these laboratories since 2007 have been below the MDA. A detailed laboratory usage survey has been included (see Appendix 1) which fully describes the research activities in these rooms.

Room 1B307: Radiochemistry Laboratory/Sample Preparation Room

This room (496 sq. ft.) was the primary sample preparation and wet chemistry portion of the laboratory. It also served as a general sample and radioactive materials storage area.

Room 1B307A: Radiochemistry Laboratory/Instrument Room

This room (145 sq. ft.) housed three gamma-ray spectrometers with low-level lead brick shielding, an alpha spectrometer, and spare electronics.

Room 1B307B: Radiochemistry Laboratory/Auxiliary Prep and Analysis Room

140G0123Q0208

Document Title

This small room (80 sq. ft.) has been used for miscellaneous purposes including sample storage, sample dewatering, ashing experiments, and RaDeCC analyses.

1B307C: Radiochemistry Laboratory/Tool and Storage Room

This room (33 sq. ft.) connects 1B307 with 1B307A and 1B307B. Sample storage occurred here.

1B309: Inorganic Geochemistry Laboratory

This room (532 sq. ft.) has been used for various laboratory operations since 1995. From

2011 - 2020, the Reston Radiochemistry Laboratory weighed mill tailing and NIST SRM

4350B (River Sediment Environmental Radioactivity Standard) samples in 1B309. These weighing activities occurred at the balance closest to the door connecting 1B307 and

1B309.

Hallways

All hallways adjacent to the radiological rooms are identified and are part of the survey.

C. Definitions/Applicable Documents (define terms that have a different meaning to different people, esp. technical ones; list publications, directives, commercial standards affecting the work). If definitions are not required for successful performance, skip C and replace with D.

D. Scope: Services to provide all equipment, labor, travel, and materials (unless otherwise provided herein) necessary for on-site surveying and decommissioning of the Reston Radiochemistry

Laboratory (1B307, 1B307A, 1B307B, 1B307C) and Inorganic Geochemistry Laboratory

(1B309).

II. WORK REQUIREMENTS

A. Technical Requirements:

The Contractor is solely responsible for site investigation and verification of actual site conditions. This statement of work outlines the required Contractor qualifications, work to be performed (including applicable standards and acceptance criteria), period of performance and required deliverables.

The Contractor shall possess a current Nuclear Regulatory Commission (NRC) license or have a State License Agreement and the NRC Form 241.

Task 1. The contractor shall provide a Final Status Survey Plan, aka Decommissioning Plan, which meets or exceeds MARSSIM protocols and standards within 10 business days after award for approval.

Task 2. The contractor shall decommission the laboratories by following the approved Final Status

Survey Plan to completion in accordance with MARSSIM protocols and standards within 15 days (three business weeks) after the USGS approves the Final Status Survey Plan.

1. Test the surfaces in the laboratories for radiological contamination in accordance with

MARSSIM protocols.

140G0123Q0208

Document Title

2. Conduct radiological decommissioning in accordance with MARSSIM protocols and based on the survey results, after the order to proceed.

a. Items or equipment surveyed with no detectable radiation above background or minimum detectable activity shall be released from radiological controls to be disposed of by the contractor as non-radioactive waste or free-released material.

b. Items surveyed with detectable contamination levels above background or minimum detectable activity shall be documented and reported to the USGS COR identifying the activity, location, and isotope if known. These items will be disposed of by the contractor in accordance with all Federal, state, and local laws, statutes, regulations, and codes.

c. Large items (e.g., instrumentation) will be surveyed in the following manner. A floor area of sufficient length and width to contain the item shall be surveyed first. Then the item shall be moved to the surveyed area. The vacant area where the item was previously positioned shall be surveyed. The item then shall be moved back to its original position and the floor area where the item was moved to shall be surveyed again. This procedure shall apply to all large items or equipment residing in the room.

d. Areas surveyed with detectable contamination levels above the release criteria, as noted in 10 Code of Federal Regulations (CFR) 20.1402 Radiological Criteria for Unrestricted Use, shall be documented, and reported to the USGS COR identifying the activity, location, and isotope if known.

e. Samples taken for removable contamination shall be counted on a liquid scintillation counter (LSC). There is no Government-furnished equipment associated with this contract. The contractor may use portable tritium counters for samples and then shall use an offsite LSC on a confirmatory basis. 100% of the samples shall be counted.

f. If items or areas are reported above Minimum Detectable Activity or Derived

Concentration Guideline Levels respectively, the contractor shall notify the USGS COR.

g. Radioactive low-level waste generated during the period of performance shall be packaged, labeled, manifested, and shipped by the contractor to the nearest licensed low-level waste disposal facility located in a Nuclear Regulatory Commission Agreement

State. Copies of manifests and export letter(s) shall be provided to the USGS COR.

h. The lowest cost shall be a consideration when selecting the nearest licensed disposal facility.

i. The contractor shall complete the MARSSIM surveys within 15 days (three business weeks) after the USGS Radiation Safety Committee-approved Final Status Survey Plan or

Decommissioning Plan has been received by the contractor.

j. Removable contamination samples shall be counted on a liquid scintillation counter only.

Use of a dual scalier detector such as a Ludlum 3030 or 2929 or equivalent are not allowed.

140G0123Q0208

Document Title

k. Other areas that are “non-radiological” are available for collection of background data.

Possible areas include nearby offices, a conference room, and other “non-radiological” labs.

Access to these areas can be gained by contacting the Reston Project Laboratories Branch

Supervisory Scientist.

l. The suspended ceilings have been in place since lab operations began and the ceilings have not been removed. From a review of operations and history of use in the rooms, it is reasonably expected that ceiling tiles are free of contamination. There is no requirement for the contractor to survey the ceiling tiles. If the contractor recommends that additional surveys of the ceiling be conducted, the USGS Radiation Safety Committee will take that into account for future work.

m. All walls shall be surveyed to a height of 10 feet.

Task 3. Miscellaneous Items.

1. Historical Site Assessment: Records are available for review and the USGS Physical Science

Technician who performed all laboratory procedures during the operational life of the laboratory is available for interviews during the period of performance. Justification can be provided for class survey unit designations. A historical usage survey for the laboratory has been provided (see

Appendix 1).

2. Interior and hallway floor drains and sinks shall be assessed as to the need to be surveyed. With the exception of a minor low-level, radioactive, sample-water discharge approved by Fairfax County

(October 2012), no radioactive material has been deposited down the drains.

3. Ventilation systems, except fume hoods, should not be required to be surveyed.

4. Contractor equipment can be stored in the building as the building will be secured after hours.

Only a select group of individuals have access to the buildings after-hours.

5. The Contractor shall dispose of any radioactive or contaminated survey media and personal protective equipment used or generated during the survey. The contractor shall provide disposal under their own disposal permits. The USGS does not maintain active LLRW disposal site use permits.

6. A radiation technician may collect the surveys provided a certified health physicist oversees the

MARSSIM survey. This allows the contractor to use lower-tiered personnel for those routine tasks that do not require a certified health physicist. However, the radiological technician or radiation safety professionals such as National Registry of Radiation Protection Technologists (NRRPT) personnel must be overseen. A certified health physicist does not need to be on site but must oversee the final survey and ensure proper procedures and sampling are conducted.

7. There is no substitution for either a radiation technician, a radiation safety professional, or the certified health physicist.

8. Hours for work conducted at this location will be 7:30 to 5:00, Monday-Friday.

Circa 2012-2014 – Several items were taken by RSO, Inc. to the hot rock shed during their Radiation Safety Support

Contract.

Circa August 2015 – Ba-133? that was found during May 2015 in 1B407 was taken to the hot rock shed for disposal.

Summer/Fall 2019 – Some produced waters, barium radium sulfate co-precipitates, as well as uranium and thorium electroplated onto planchets were taken to the hot rock shed.

Notes

Flooring throughout 1B307, 1B307A, 1B307B and 1B307C was replaced in April 2018. During this time, items were stored in the hallway, 1B309, 1B303, and 1B209.

Two lengths of fume hood ducts were replaced from laboratory fume hoods in the main section of the laboratory to the edge of the lab at the wall to 1B309 in February 2011. Swipes taken on the ducts were below the MDA.

1B309

This neighboring room (532 sq. ft.) was used for laboratory operations from 1995 – 2011 by two now-retired employees.

According to the research collaborator (no radioactive materials were used in the laboratory during this time. From 2011 -

2020, the Reston Radiochemistry Laboratory weighed mill tailing and NIST SRM 4350B (River Sediment Environmental

Radioactivity Standard) samples in 1B309. These weighing operations occurred at the balance closest to the door connecting 1B307 and 1B309 (i.e., on the bench adjoining the wall shared by 1B309 and 1B219).
