1.1 Background

The Deep Underground Neutrino Experiment (DUNE) at the Long Baseline Neutrino Facility (LBNF) was borne out of the 2014 U.S. Particle Physics Project Prioritization Panel (P5) recommendations. The recommendations called for formation of a truly international collaboration for constructing a US-based long-baseline neutrino oscillation experiment with a powerful neutrino beam (~MW scale), a massive liquid argon TPC (40 kt) sited several hundred kilometers downstream of the neutrino source and deep underground, and a smaller detector just downstream of the beamline. Together these elements will have the capability to unambiguously determine the neutrino mass ordering, search for CP violation in the lepton sector, search for proton decay, and observe neutrinos from core collapse supernovae.

The LBNF/DUNE-US Project is the DOE-funded construction project to create the facility and contribute US scope to the international DUNE Collaboration. The major participants in the overall LBNF/DUNE enterprise are the international DUNE collaboration, the LBNF/DUNE-US construction project, the DOE, international funding agencies, Fermilab (in Batavia, Illinois) as the host laboratory, and the Sanford Underground Research Facility (SURF, in Lead, South Dakota), where the far detector will be located.

Figure 1 illustrates the general underground work area at the SURF (far) site.

4.1 Task 1: Environmental Safety and Health (ESH)

A part of the Exhibit A For Supply and/or Services Subcontracts the Environmental, Safety, and Health Certification (ESHC) form will be provided to the Subcontractor for signature, indicating that the Subcontractor understands the requirement to comply with the following:

10 CFR Part 851, DOE Worker Safety and Health Program

29 CFR 1910 OSHA Standards

The Subcontractor and sub-tier subcontractors shall comply with industrial hygiene and FFDG requirements.

Listed below are the on-site safety procedures where the risk of fire or spill is highest, during fuel dispensing.

Site assessment: Before beginning, visually inspect the site for any potential hazards. Look for ignition sources near the fill area, excessive vegetation, or unsecured fill caps. In winter, check that access ways are free of ice and snow.

Vehicle positioning: Park the truck to allow safe and easy access to the fill port without stretching hoses.

Ignition control: Prohibit smoking, open flames, or other ignition sources in the fueling area.

Avoid using electronic devices like cell phones while fueling.

Dispensing process:

Long-Baseline Neutrino Facility (LBNF) / Deep Underground Neutrino Experiment (DUNE) - US Page 4-5

Grounding/Bonding: Establish a secure ground between the truck and the stationary tank.

Containment: Place a drip/spill pan underneath the fill port to catch any minor spills or drips.

Tank verification: Before unloading, confirm that the fuel is being delivered into the correct tank and that the tank has enough capacity. Never fill "blind fills" where the capacity cannot be verified.

Monitoring: The driver must remain at the nozzle for the entire fueling process and never leave the dispensing unattended.

Emergency response: Keep a spill kit easily accessible and be trained in emergency response procedures.

The Subcontractor shall take the following steps to prevent product spills, protecting the environment and avoiding costly cleanups.

Subcontractor shall notify FFDG Technical Representative of any and all spill events.

Check tank levels: Always gauge the storage tank to determine the available capacity before delivery. Double-check the delivery ticket to ensure accuracy.

Manage flow: Limit the delivery rate to match the tank's vent capacity. This prevents tank rupture and releases.

Never top off: Overfilling is prohibited. Stop dispensing as soon as the automatic shut-off clicks off.

Inspect receiving equipment: Check that the tank's overfill prevention devices are working correctly and that all fill and gauge caps are secure and clearly marked.
