BISMARCK, N.D. (AP) — North Dakota regulators have fined CenturyLink Inc. $10,000 for violating the state's excavation notice system.

The Public Service Commission says the communications company violated the state's "one-call" law 25,701 times last year.

State law requires excavators to call a "one-call center" at least 48 hours before they begin digging, so the center has time to notify the excavator whether there are any pipelines or utility facilities buried there.

Utilities are required to provide "positive responses" to the center to ensure the digging area has been inspected and marked. The company says in regulatory filings its responses to the center were being rejected due to an incorrect password.

Under the agreement accepted Wednesday, the PSC suspended $15,000 of the fine if no other violations occur in five years.
