1.0 SCOPE OF WORK & COORDINATION

1.1 Point of Contact

The Fermi Forward Discovery Group, LLC (FFDG) Point of Contact shall be the first line of contact with the Subcontractor’s field personnel. He/she is responsible for auditing to ensure that the Subcontractor is following established and accepted ES&H practices while on site. Point of Contact is assigned for low-risk work activities that typically do not require a written job specific Hazard Analysis.

1.2 Definitions

Competent Person: One who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary, hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate the identified hazards. Duties related to ES&H shall take precedence over other duties.

Fermi Forward Discovery Group (FFDG): The entity that manages Fermi National Accelerator Laboratory and leased space for the U.S.

Department of Energy’s (DOE) Office of Science.

FFDG ES&H Coordinator: A FFDG person responsible for ES&H guidance, periodic work site visits, support for the FFDG Installation Coordinator, and provide oversight of the Subcontractor’s safety program. The ES&H Coordinator will review Hazard Analysis and training documentation for ongoing work activities. Any deficiencies noted shall be brought to the attention of the FFDG Installation Coordinator for follow-up with the Subcontractor. The ES&H Coordinator has authority to stop work activities for imminent danger, fatality, or major environmental release, but does not have authority to direct changes in the work scope of the project or the Subcontractor’s means and methods of the installation/assembly.

Subcontractor Field Superintendent: One who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary, hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate the identified hazards.

The superintendent’s role is to run the day-to-day operations and control the short-term schedule. In addition, the superintendent includes important quality control and coordination responsibilities with sub-tier contractors/vendors. FFDG also requires the Subcontractor Field Superintendent to have completed an OSHA 30-hour construction safety course. Duties related to ES&H shall take precedence over other duties.

Imminent Danger: A hazard which, if allowed to persist, is likely to cause an accident that will result in death, injury, property damage, or environmental impairment.

FFDG (Service) Installation Coordinator: A FFDG Installation Coordinator will be assigned for subcontracts involving work activities with potential risk. He/she shall be the first line of contact with the Subcontractor’s field personnel and the Point of Contact, and is responsible for auditing to ensure that the Subcontractor is following established and accepted ES&H practices while on site.

Integrated Safety Management (ISM): ISM is defined as a system for performing work safely and in an environmentally responsible manner. The term “integrated” is used to indicate that the ES&H management systems are normal and natural elements of accomplishing work. The intent is to integrate the management of ES&H with the management of the other primary elements of installation: quality, scope, cost, and schedule.

FFDG subscribes to the philosophy of ISM by following the program outlined in this section.

The ISM core functions are implemented by robust daily work planning of installation activities. The ISM core functions include 1) define the scope of work, 2) identify and analyze the hazards, 3) develop and implement hazard controls, 4) perform work with controls, and 5) provide feedback for continuous improvement.

FFDG also requires this of Subcontractors and sub-tier subcontractors.

FFDG Procurement Administrator: A FFDG person responsible for and specifically assigned to the project, who is responsible for negotiating and administering the subcontract terms and

Exhibit A | August 2025 3 of 14 conditions. All modifications to the subcontract shall come from the Procurement Administrator or designee, in writing. The Procurement Administrator or designee is the sole entity that can modify the subcontract or initiate change orders.

FFDG Project Manager: A FFDG person responsible for managing, phasing, and ensuring the project is meeting key milestones.

Qualified Person: One who, by possession of a recognized degree, certification, or professional standing, or who by extensive knowledge, training, and experience, has successfully demonstrated his or her ability to solve or resolve problems relating to the subject matter, the work, or the project.

South Dakota Science and Technology Authority (SDSTA): The entity that manages the Sanford Underground Research Facility.

Sanford Underground Research Facility (SURF):

Underground research facility, located in Lead, South Dakota.

Subcontractor’s Safety Officer/Representative:

When required by the subcontract, the Subcontractor’s Safety Representative shall have completed the OSHA 30-hour construction safety course and have a minimum of 10 years of construction experience consistent with the type of activities included in the Statement of Work.

Subcontractor’s ES&H Program: Subcontractor’s (corporate) company policies and procedures to ensure operations comply with applicable safety and occupational health laws and regulations and protect the safety and health of employees and members of the public.

Stop-Work Order: A definitive statement made openly to another individual that an imminent danger situation exists and therefore, all related work must stop immediately.

An JHA details the specific hazards associated with the work activities and mitigating actions (including PPE in accordance with ANSI, OSHA, and NFPA 70E) that the subcontractor will take to reduce or eliminate the risk of injury. Safety Data Sheets (SDS) or Safety Data Sheets (SDS) and any specific procedures (confined space, LOTO) are to be submitted as part of this JHA. The JHA shall be submitted for FFDG review and acceptance prior to commencement of work. Each employee will acknowledge reading and understanding the JHA by placing his/her signature on the signature page. The JHA is a dynamic document which will require modification as the project moves from start to finish. As the JHA is updated, the employees must be advised of the new information.

Work Activity Plans (WAP) are task-specific documents that contain the relevant step-by-step installation instructions. They are intended for use by workers during installation to ensure that field operations are conducted safely and meet project requirements.

Templates of JHA, FLRA, WAP, and SOP can be provided upon request.

2.4 Stop Work Activity

Any employee may stop a work activity if there is imminent danger of serious injury, fatality, or major environmental release. If the hazard cannot be abated in a timely manner, the work activity shall be stopped and the Service / Installation Coordinator/Point Contact and Procurement Administrator shall be contacted.

2.5 Off Hours / High Hazard Work
