Ensuring Safe Digging on the Farm

As an agricultural operator, it's crucial to recognize that underground utilities can be present even beneath farm fields. Hitting these utilities can disrupt your operations, cause serious safety hazards, and lead to costly repairs. To avoid these issues, the 811 service is essential for all your digging projects, including farming activities.

The Importance of 811 for Agricultural Operators

Using the 811 service before you dig is not just a recommendation—it's a necessary step to ensure the safety and efficiency of your farming operations. Utilities like gas lines, water pipes, and electrical cables can be buried underground, and damaging them can have significant consequences for your farm and community. By contacting 811, you help protect your investments and maintain a safe working environment.

HOW DOES 811 WORK?

Work Step Image

Pre-Mark your Project Area in White.

Before notifying 811 of your planned digging project, you will need to pre-mark your proposed project area. These markings will help utility locators quickly identify where the digging is taking place.

Work Step Image

Contact 811

Simply dial 811 or submit your request online a few days before you plan to dig. Provide your project area location and information about your project. Utility owners will be notified about your digging project and begin responding to your request.

Work Step Image

Wait for Markings

Utility companies will send professional locators to your project area to mark the location of buried lines with flags or paint. They may also choose to share utility location information with you or notify you that they do not operate a utility within your project area. This service is free of charge. Wait until each utility operator on your request has responded before you begin digging.

Work Step Image

Confirm the Marks

Verify that all the utility lines have been marked and that each utility operator on your ticket has responded. IF you need clarification, call 811 again for assistance.

Dig with Care

Use the marks as a guide to avoid hitting utility lines. Use hand tools when digging near the marks and proceed with caution.

Area Of Continual Excavation (ACE)

The Area of Continual Excavation (ACE) Ticket is a special type of locate request designed to meet the unique needs of agricultural operators and certain flood control facility operators in California. This ticket allows for a continual excavation request that is valid for one year, as opposed to the standard 28-day ticket, making it easier for ongoing agricultural activities to remain compliant with the state's "call before you dig" laws​ (EnergySafety)​​ (EnergySafety)​.

Requirements for ACE Tickets

ACE Tickets are only available in a location where excavation is part of the normal business activities of agricultural operations and flood control facilities.

Contact 811 to submit your ACE Ticket request. This can be done by phone or online. Be sure to specify that you are requesting an ACE Ticket for agricultural purposes.

On-Site Meetings and Agreements

If your excavation project involves working within 10 feet of a high priority subsurface installation, an on-site meeting between a representative of the excavator and the operator of the high priority subsurface installation is required. This meeting ensures that both parties have a clear understanding of the utility locations and any potential conflicts.

Key Points for On-Site Meetings:

  • Mutually Agreed Date and Time: The meeting must be scheduled at a mutually agreed upon date and time at the location of the excavation.
  • Authorized Representatives: Representatives attending the meeting must be authorized to enter into agreements and have all relevant operational information.
  • Documentation: If there are disagreements about the location of the utilities, the utility operator must provide documentation or expose the facility using hand tools or vacuum excavation to demonstrate its exact location​
  • Link to the ACE Agreement for on CA Underground Safety Board’s Website

For areas that do not contain or are more than 10 feet away from high priority subsurface installations, an on-site meeting is optional but recommended to ensure safety and compliance.

Tickets are discussed:

High Priority Subsurface Installations

Under California Government Code 4216, a High Priority Subsurface Installation is an underground line that can cause serious injury, environmental damage, or major service outages if damaged.

They include

High-pressure natural gas pipelines

Pipelines operating above 60 pounds per square inch (psig)

Petroleum pipelines

Lines that carry oil, fuel, or other petroleum products

Pressurized sewage pipelines

Sewer lines that move waste under pressure, not gravity

High-voltage electric lines

Underground electric lines carrying 60 kV or more

Hazardous materials pipelines

Any pipeline carrying substances that could be dangerous to workers or the public if damaged

What This Means for Agricultural Work

If your farming operation plans to dig within 10 feet of an HPSI, extra steps are required before excavation can begin:

  • An on-site meeting with the utility operator is required to review the location, marking, and excavation plan.
  • An Area of Continual Excavation (ACE) agreement form must be completed and approved before work starts.
  • These steps help ensure everyone understands where the line is, how it will be protected, and how excavation can proceed safely.
