59.1 Policy

Only trees in which tritium levels are not distinguishable from regional background levels may be removed from the Berkeley Lab site.
The Vegetation Sampling and Management Program at Berkeley Lab ensures that tritium-contaminated trees are not removed from the Berkeley Lab site.

59.2 Scope

This policy applies to trees that:

The restricted area surrounding Building 75 on the Berkeley Lab site where tritium levels in trees exceed the regional background is shown in Work Process B.

59.3 Applicability

Berkeley Lab employees, visitors, affiliates, and subcontractors who cut down trees on the Berkeley Lab site

59.4 Exceptions

If analytical results show tritium levels that are not distinguishable from regional background levels in a tree within the area where tree removal is restricted, then that tree may be removed from the Berkeley Lab site (DOE Berkeley Site Office, 1999).

59.5 Roles and Responsibilities

Role

Responsibilities

Supervisors

  • Ensure that environmental laws, regulations, and policies are followed
  • Request assistance from the Environmental Services Group for technical advice on vegetation management operations and what would be an appropriate compliance strategy
  • Ensure that vegetation management activities are performed within acceptable operating standards and that any required records are current
  • Notify the EHSS Division immediately of any unauthorized tree removal

Employees

  • Follow applicable environmental laws, regulations, and policies
  • Be fully aware of the environmental impact of their tree removal activities and comply with all requirements that govern those activities
  • Take immediate action to stop unauthorized tree removal, and report all instances of unauthorized tree removal to the EHSS Division

Environmental Services Group

  • Develops Laboratory policies and procedures to ensure that tree removal operations are conducted in an environmentally safe manner and in full compliance with all applicable environmental laws and regulations and DOE orders
  • Prepares environmental compliance plans and reports as mandated by laws and regulations and DOE orders
  • Assesses current and planned Berkeley Lab tree removal activities and assists in defining environmental protection compliance actions
  • Reviews planned tree removal operations in accordance with ESG Procedure 270, Assessing Tritium in Trees for Removal
  • Provides technical assistance and participates in discussions regarding tree removal operations with Berkeley Lab employees, regulatory agencies, concerned public citizens, communityorganizations, and the media
  • Curtails or suspends any operations that pose an immediatedanger to members of the public or the environment
  • Investigates reports of unauthorized tree removal, and notifies federal, state, and local authorities in a timely manner, asrequired
  • Coordinates and represents Berkeley Lab activities during environmental audits and inspections by regulatory agencies and DOE
  • Responds to information requests from the public
  • Participates in DOE audits of off-site analytical laboratories to ensure the quality of analytical results received for environmental monitoring programs

59.6 Definitions

Term

Definition

Environmental monitoring

The collection and analysis of environmental samples or direct measurements of environmental media. Environmental monitoring consists of three major activities: effluent monitoring, environmental surveillance, and meteorological monitoring.

Regional background

Tritium levels in trees in the region beyond the influence of Berkeley Lab activities, which are typically less than the lowest activity the analytical laboratory can detect

Restricted area

An area surrounding Building 75 where tritium levels in trees exceed the regional background (and where tree removal is restricted)

Tritium-contaminated trees

Trees with tritium at levels that can be detected by laboratory analysis

Unauthorized tree removal

Removing trees or wood chips from the restricted area without obtaining confirmation from the Environmental Services Group that tritium levels in the trees are not distinguishable from regional background levels

59.7 Required Work Processes

Work Process A. General Requirements and Flowchart

The following flowchart guides Facilities Division and subcontractor personnel in determining how to manage trees in the tritium-contaminated area at Berkeley Lab:

 

Work Process B. Map of Restricted Area Where Trees May Not Be Removed

 To prevent unauthorized tree removal, use the map (below) to determine whether trees are in the contaminated (pink-shaded) area. If still unsure, contact the Environmental Services Group at ext. 7616.
