Assurance and Construction Inspection Procedure (SLAC-I-770-0A22C-001-R003).
Responsibilities of UTRs or Project Engineers include, but are not limited to:
• Apprising subcontractors of SLAC and DOE safety criteria prior to construction.
• Informing subcontractors of the hazards routinely found at SLAC.
• Conducting periodic inspections of subcontractor construction areas to evaluate the
quality of the subcontractor's safety compliance program and quality of work.
• Providing information to SLAC Citizen Safety Committees as required or requested.
• Communicating and resolving safety or quality deficiencies identified by SLAC
personnel with the subcontractor.
• Receiving subcontractor accident reports and compiling information for reporting to
the DOE.
Enforcement of subcontractor requirements is carried out by the SLAC Purchasing
Department and may involve with holding payment(s) if applicable codes and standards are
not met.
13.5.2 Tunnel
The LCLS configuration provides for two experimental areas (near and far hall), joined
by a tunnel housing that contains the beam transport line. Early discussions and review of the
tunnel portion of the project, helped determine the need for two separate tunneling
techniques. Both of which may be required during construction. The two techniques that may
be used include: “cut and cover”, which in essence is akin to trenching but on a much larger
scale; and the use of tunnel boring equipment, for those portions of the beamline housing that
cut and cover would be either technically or economically infeasible. While both of these
methods have been used at SLAC for previous projects, they are infrequent operations and
the hazards encountered are not familiar ones to the SLAC community. Accordingly the
safety scope of this type of operation is well defined in both: the California Code of
Regulations, Chapter 4. Division of Industrial Safety, Subchapter 20, Tunnel Safety Orders,
and Title 30, Code of Federal Regulations, “Mineral resources,” Subchapter I Mine safety
and Health Administration, Department of Labor. Subcontractors with mine safety expertise
and experience will be used to provide the tunneling service.
13.6 Hazardous Materials
During the installation and operation phases of the LCLS it is anticipated that a minimum
amount of hazardous materials will be used, examples would be paints, epoxies, solvents, oils
and lead in the form of shielding, etc. There are no current or anticipated activities at the
