811
The national call before you dig number. Since calls made to 811 are automatically routed to the nearest one call center, excavators and contractors can also call 811 to request that lines be marked.
10-Day Window
If an excavator postpones a project’s start date by less than 10 working days, the excavator does not need to contact New York 811. If more than 10 working days have elapsed since lines were marked, however, a new locate request must be submitted.
Automated Positive response, APR or TicketCheck®
Communication with the excavator prior to excavation to ensure that all contacted (typically via the notification centers) owner/operators have located their underground facilities and have appropriately marked any potential conflicts with the areas of planned excavation.
Code Rule 753
Enforced by the Public Service Commission, New York State Code Rule 753 (also referred to as Part 753, Industrial Code 53 or Code 53) addresses the protection of underground facilities. The code includes the following major components:
- All owners of underground facilities must be members of one of the two one call centers in the state (New York 811 and UDIG NY).
- All New York contractors excavating on commercial or residential property must notify their local one call center two working days prior to the project’s excavation date.
Code Rule 753 also includes detailed information on fines, the tolerance zone, personal property and line marking color codes. Professional excavators are expected to know and obey this code.
Color Codes
When utility company representatives mark a location, they use different colored flags and/or paint to identify the type of underground service. Click here to view a color code chart.
Damage
Any destruction of an underground facility or its protective coating that requires repair work. If damage occurs, stop excavation operations immediately and contact the appropriate utility company (if known) as well as New York 811, even if damage appears minor. If a substance starts releasing into the air, such as natural gas, call 9-1-1. For your safety, walk away immediately and take steps to clear the area. Don’t try to repair or stop a leak yourself or use anything that might create a spark, such as a cell phone.
Damage Prevention
An initiative to prevent damage to underground utility lines or facilities caused by unsafe digging.

Demolition
The total or partial wrecking, razing, rending, moving or removal of any structure. Excavators must request a pre-demolition conference with all member operators who have underground facilities at or near the demolition area at least seven working days before their project’s start date.
Excavation

ITIC
A real-time, Web-based ticket-entry system for excavators, contractors and utility companies. Through this easy-to-use system, users can input, manage and update their tickets, all from the convenience of their personal computer. Prior training is required to use this system. To sign up for ITIC or learn more, call 811.
Locate Request
A request submitted by a contractor, excavator or homeowner to mark underground utility lines in the area they plan to dig.
Mark Out
The process of marking underground utility lines with paint or flags. The term “mark outs” is also used to refer to the actual paint lines or flags on a property (i.e. “There were three mark outs on the property.”)
Members
By law, companies that own or operate underground utility lines must join one of the two one call centers in the state of New York. New York 811’s member network includes “participating members,” which are utility companies (e.g. water, sewer, telecommunications, natural gas), municipalities and others with a stake in protecting New York’s underground infrastructure. “Sustaining members” do not own underground facilities but have an interest in damage prevention.

New York 811
A nonprofit organization that acts as a communications link between utility companies and individuals planning any digging activity in the five boroughs of New York City and Nassau and Suffolk Counties on Long Island. While New York 811 does not physically mark utility lines or underground facilities, we do relay digging and excavation requests to our extensive member network.
Notice

A notice includes the name, address and telephone number of the excavator or excavation company; name of the field contact person; worksite address; extent and dimensions of the planned work area, means of excavation or demolition and whether or not explosives are to be used; and project start date.
Notification Center
Acts as a communications link between utility companies and individuals planning any digging activity. After receiving a locate request from a homeowner, contractor or excavator, call center operators notify affected utilities to visit the work site and mark the locations of buried utility lines with paint or flags. New York 811 is a one call center.

Ticket
An official notification of your request that New York 811 sends to all member utilities with lines in your area.
Tolerance Zone
A buffer that extends one half of the utility line’s known diameter plus two feet on either side of the center line. If the diameter of the underground facility is not known, the tolerance zone is two feet on either side of the designated center line. Hand tools are required when working in the tolerance zone until the exact facility location is verified. Click here for a helpful diagram.
Underground facility
Many utility company facilities are located underground and out of sight. These facilities may include electric, natural gas, steam, telecommunications, water, sewer and oil lines. To avoid dangerous and costly damage to these lines, it’s important that you contact New York 811 before conducting mechanized excavation work.
