Operator Information


Federal Inspection and Enforcement Data

NORTHERN NATURAL GAS CO

(Operator ID:13750 - CURRENTLY ACTIVE OPID)

Main Operator Report Page - Incidents and Mileage - Federal Inspection and Enforcement Data - More Pipeline Operators

The reports below provide inspection and enforcement data since 2006. This information includes only completed (not planned or ongoing) inspections and the enforcement actions pursued at the Federal level by PHMSA on Federally-inspected mileage. The number, type, inspection days, and date of inspections conducted by PHMSA are included, as well as both a summary of and specific details pertaining to enforcement cases against this operator.

In some cases, State pipeline safety agencies also provide oversight and enforcement on certain intrastate pipeline facilities (State-inspected mileage). Inspections and enforcement by PHMSA's partner State agencies are not included in these reports; however, information on State-initiated enforcement action is available at State Pages.

For more information on each inspection type see the Inspection Activity Glossary.

Site-Specific Field Inspections - Includes inspections and other compliance-related activities conducted at specific facilities or along specific lengths of pipelines. These inspections/activities include on-site field verification of an operator's implementation of procedures and programs associated with corrosion control; pipeline inspection, testing, and repairs; emergency safety devices and remote instrumentation; right-of-way marking; valve operability; equipment maintenance; interaction with emergency services officials; participation in One-Call Systems; personnel training and qualification; emergency response preparedness; and other pipeline safety and compliance tasks.

System-Wide Program Inspections - Includes inspections and other compliance-related activities that cover pipeline safety programs and processes that apply broadly across an operator's entire pipeline system or network of pipeline facilities. These inspections/activities include those which cover operating, maintenance, and emergency procedures; integrity management, operator qualification, control room management, public awareness, and damage prevention programs; spill preparedness and response planning; and, procedures, processes, and plans covering other pipeline safety and compliance activities.

Targeted Inspections/Investigations - Includes inspections, investigations, and other activities related to specific pipeline safety issues or concerns, or areas which have been targeted for special review or emphasis. These inspections/activities include failure investigations, follow-up activities for identified compliance or safety issues, investigations into public concerns or complaints, new construction inspections, drug and alcohol program inspections, and other special-focus inspections or investigations.

Cases Initiated: These are the yearly total of civil administrative enforcement actions that PHMSA has brought against pipeline owners and operators. It does not reflect those cases which the agency has referred to other Federal officials for criminal prosecution, nor does it include more egregious civil cases that are referred to the U.S. Department of Justice for judicial enforcement. The table shows the total number of Corrective Action Orders, Notices of Probable Violations, Notices of Amendment, Warning Letters, and Notices of Proposed Safety Orders issued in a given year.

Cases Resolved: These are the yearly total of PHMSA actions taken to resolve the various types of enforcement actions against operators. This includes the number of Corrective Action Orders, Final Orders, Notices of Amendment, and Consent Orders that have either been closed or issued in a given year. When an enforcement action is shown as "closed", PHMSA has verified that all of the corrective actions have been successfully completed and that any inadequate procedures that were identified successfully addressed. Enforcement actions shown as "issued" mean that corrective actions have been established that are acceptable to PHMSA, and that civil penalty assessments have been finalized.
