A missed locate or inaccurate marking can lead to damaged gas lines, broken water mains, and costly repairs that cascade into safety hazards and legal liability. If your utility locating service failed to meet standards—whether they missed lines, marked them incorrectly, or failed to show up within the required timeframe—you have concrete steps to document the failure and file a formal complaint. Here's how to build a strong case and escalate appropriately.
Gather Documentation Immediately
The moment you discover a problem with utility locating work, start collecting evidence. Photograph or video-record the marked (or unmarked) areas, focusing on any damage to underground utilities that resulted. Note the date, time, and name of the locating technician if visible on their vehicle or uniform.
Request a copy of the locate ticket, which shows the ticket number, request time, scheduled date, and which utilities were requested. If damage occurred, get written statements from anyone who witnessed it, and photograph the damage from multiple angles with timestamps visible if possible.
Check Your State's 811 Call Center Requirements
In most U.S. states, one-call centers operate under the 811 system and are regulated differently than private locating companies. Call your state's 811 center directly (dial 811 or check their website) and confirm what happened on your ticket.
Ask for:
- The exact timestamp of your locate request
- Confirmation of which utilities were marked as due
- Whether a ticket was created and assigned
- Any notes from the locating technician
If the 811 center failed to properly process your request or assign it within required windows (typically 2–3 business days), they bear responsibility. If they assigned the ticket but the contractor failed, document that too.
File a Complaint with the Utility Locating Company
Contact the locating service directly with your ticket number and a clear description of what went wrong. Specify:
- Date and time of the original request
- Whether no technician arrived, or if they arrived late
- Whether all requested utilities were marked
- Any specific damages or safety issues that resulted
- Your expected resolution (reimbursement for repairs, penalty, or corrected locate)
Keep all correspondence written (email preferred). Most locating companies have 15–30 days to respond to complaints under Common Ground Alliance (CGA) standards, though timelines vary by state and contract.
Escalate to Your State Regulatory Body
If the locating company ignores you or denies liability, escalate to your state's Public Utilities Commission (PUC) or equivalent agency. Each state handles utility regulation differently:
- Some states require locating companies to hold permits and respond to complaints filed with the PUC
- Others delegate oversight to the 811 call center operator
- A few states require bonding or insurance minimums for locating companies
Search "[Your State] Public Utilities Commission complaint" and file a formal complaint online or by mail. Include your documentation, ticket number, and timeline.
Consider the Damage and Liability Angle
If the missed locate resulted in actual damage to underground utilities, your complaint carries weight. Repair costs for accidentally ruptured gas lines, water mains, or fiber optic cables run $2,000–$15,000+ depending on depth and location.
Insurance typically covers locating company liability for damages caused by failure to mark or marking errors. Request the locating company's insurance information and file a claim directly if they're unresponsive. Include repair estimates and invoices with your claim.
Know Your Rights Under CGA Standards
The Common Ground Alliance publishes Best Practices for locating services, which most states reference in regulations. Locating companies should:
- Respond within the state's required timeframe (usually 2–3 business days)
- Mark utilities accurately using standard colors and symbols
- Mark the full length of requested utilities
- Provide the ticket number on-site
If they breach these standards, cite them in your complaint to strengthen your case.

Frequently Asked Questions
Q: How long do I have to file a complaint about missed or inaccurate utility locating? Most states allow 1–3 years under tort law, but file within 30–60 days of discovering the issue to preserve evidence and while the locating company still has fresh records.
Q: Can I sue a locating company for damages if they missed a line? Yes, if they breached duty and caused measurable damage, but check your state's caps on liability and whether the locating company carries insurance (most do).
Q: What's the difference between filing with my state's 811 center versus the locating contractor directly? The 811 center dispatches the ticket; the contractor performs the work. File with both—the 811 center manages compliance, and the contractor is liable for execution failures.
