SB 275 Delaware Senate · 153rd General Assembly (2025-2026)

AN ACT TO AMEND TITLE 26 OF THE DELAWARE CODE RELATING TO THE UNDERGROUND UTILITY DAMAGE PREVENTION AND SAFETY ACT.

Summary
This Act updates and clarifies the Underground Utility Damage Prevention and Safety Act (UUDPSA), which dates from the mid-1990s. Specifically, the Act clarifies the obligations of facility owners and facility operators, which the Act defines as the person or entity that owns, operates, or controls an underground or submerged conductor, pipe, or structure used to provide electric or communications service, or an underground or submerged pipe used to carry, provide, or gather gas, oil, sewage, water, or other liquid service. Under the Act, in addition to their existing obligations under the UUDPSA, facility owners and facility operators must respond to requests from an excavator concerning the location of their facilities within 3 business days after receipt of the request, and must provide information to the excavator via the Owner/Operator/Excavator Information Exchange System, which is an interactive system that facilitates communication for that purpose. In addition, "designers," meaning an architect, engineer, or other person who prepares or issues a drawing for a construction or other project requiring excavation or demolition work, are required to meet with a facility owner or facility operator who requests more information on the scope of a project and to make reasonable efforts to prepare construction drawings in a way that avoids damage and minimizes interference with facilities in the construction area. "Excavators," meaning any person proposing to engage in excavation or demolition work, must ascertain the location and type of facilities by contacting the Owner/Operator/Excavator Information Exchange System, and may not begin excavation until a positive response code of "clear" or "no conflict" or "marked" is received from each facility owner or facility operator through the Owner/Operator/Excavator Information System. In the event of an emergency that the excavator discovers or creates, the excavator must immediately notify the occupants of the premises, and, in the event of damage to a facility by the excavator resulting in the escape of a flammable, toxic, or corrosive gas or liquid, or other event that poses a danger to life, health or property, the excavator must immediately notify 911 and the facility owner or facility operator. The excavator is required to exercise due care and take all reasonable steps to avoid injury or interference with facilities, and, in the case of a complex project, to meet with the facility owner or facility operator or their agents before construction begins. The Utilities Service Protection Center of Delmarva, Inc. is required to provide for the approved notification center that, among other things, receives and records information regarding the location of facility owners' and facility operators' facilities within the State and notice by excavators and designers of intended excavation and demolition activity and notifies facility owners and facility operators of the information received from excavators and designers. A facility owner's or facility operator's failure to perform an act required under the UUDPSA is subject to a civil penalty of up to $1 million, for violations that result in a death; up to $500,000 for violations causing damage to a structure, and up to $100,000 for all other violations. For all violations other than those resulting in death or damage to a structure, the Public Service Commission of Delaware may determine that training provided by the approved notification center may be substituted in lieu of a civil penalty. The imposition of a civil penalty does not prevent any party from obtaining civil damages for personal injury or property damage in a private action. Civil penalties will be used by the approved notification center for public awareness programs, training and education programs for members and violators of the UUDPSA, improvements to the approved notification center, or to reduce the cost to members of the approved notification center. This Act also makes technical corrections to conform existing law to the standards of the Delaware Legislative Drafting Manual.

HA 1 to SB 275 Bill Text · 11 edits
MAJOR
SB 275 comprehensively overhauls Delaware's Underground Utility Damage Prevention and Safety Act, replacing the term 'operator' with 'facility owner or facility operator' throughout, adding a mandatory positive response system that blocks excavation until all facility owners confirm their facilities are marked or clear, and dramatically increasing penalties from misdemeanor fines of up to $1,000 to civil penalties of up to $1 million for violations resulting in death. The bill also adds new duties for designers, defines a 24-inch tolerance zone where mechanized equipment is prohibited, and shifts enforcement authority to the Public Service Commission for most violations while reserving the Attorney General for cases involving death or structural damage.
SCOPE

Replaced the term 'operator' with 'facility owner or facility operator' throughout the act, broadening who bears legal duties. Also replaced 'utility lines' with 'facilities,' a broader defined term covering underground or submerged conductors, pipes, and structures used for electric, communications, gas, oil, sewage, water, or other liquid service.

The House Amendment 1 (which removed 'state and' from the Test Holes definition, limiting it to 'local jurisdiction') was not incorporated into the final enacted text. The final bill retains 'state and local jurisdiction' in that definition.

REQUIREMENT

Excavators may not begin work until they receive a positive response code of 'clear,' 'no conflict,' or 'marked' from each facility owner or operator through the new Owner/Operator/Excavator Information Exchange System. This is a hard gate that did not exist in prior law.

Facility owners and operators must now: provide positive responses via the Information Exchange System even if they have no affected facilities; use APWA color codes for markings; train locating personnel in industry standards; install tracer wire on new non-metallic pipes; locate all facilities in State highway rights of way; and participate in preconstruction meetings for complex projects.

Designers (architects, engineers, or others who prepare construction drawings) must now meet with facility owners who request more project information and make reasonable efforts to prepare drawings that avoid damage and minimize interference with facilities. They must also show facility type, owner name, and notification instructions on their drawings.

Excavators must now: notify 911 and the facility owner immediately if damage results in escape of flammable, toxic, or corrosive gas or liquid; remain on site until responders arrive; use test holes to verify location of hazardous or flammable facilities within 5 feet of marked facilities; follow published best practices for horizontal directional drilling; and notify the notification center of any changes to excavation location, scope, or duration.

TIMELINE

Notification timelines changed from '2 working days' to '3 business days' minimum and from '10 working days' to '12 business days' maximum for excavators to notify the notification center. Facility owners must respond within 3 business days (previously 2 working days). Excavation tickets are valid for 12 business days.

ENFORCEMENT

Penalty structure completely replaced. Old law imposed misdemeanor fines of $100-$500 (first offense) and $200-$1,000 (subsequent). New law imposes civil penalties up to $1,000,000 for violations causing death, $500,000 for damage to a structure, and $100,000 for all other violations. The Public Service Commission handles most enforcement; the Attorney General handles death and structural damage cases.

For violations not involving death or structural damage, the Public Service Commission may substitute training provided by the notification center in lieu of a civil penalty. All collected penalties must be used for public awareness programs, training, notification center improvements, or reducing member costs. Facility owners cannot pass penalty costs to customers through rates.

DEFINITION

Added numerous new definitions including: tolerance zone (24 inches from facility where mechanized equipment is prohibited), complex project, design ticket, meeting ticket, emergency notice, positive response, white lining, trenchless technology, vacuum excavation, and the Owner/Operator/Excavator Information Exchange System.

ELIGIBILITY

A facility owner or operator that fails to become a member of the approved notification center loses its right of recovery from an excavator if damage occurs because the excavator could not notify the non-member. This creates a financial incentive for all facility owners to join the system.
