The details of this accident investigation and the resulting safety recommendations may be found in the attached report, which can also be accessed at http://www.ntsb.gov. As a result of this investigation, we identified the following safety issues: • Inadequate project planning and risk assessment. • Ineffective pipeline damage prevention. • Lack of pipeline hazard training. Accordingly, the NTSB makes the following safety recommendations to PHMSA. Additional information regarding these recommendations can be found in the noted sections of the report. • In collaboration with Coastal and Marine Operators and the Council for Dredging and Marine Construction Safety, develop recommended practices and processes for pipeline operators and dredging companies to obtain and use accurate pipeline location data during planning and one-call locating activities for pipelines both in and near project locations. (P-21-018) (See section 2.4.1) • In collaboration with Coastal and Marine Operators and the Council for Dredging and Marine Construction Safety, develop guidance for 67694#
Page 32 excavators to clearly identify proposed dredging boundaries for dredging projects before notifying one-call centers by either physically marking the boundaries where practicable, or identifying the boundary with accurate location data. (P-21-019) (See section 2.4.2) • Include criteria for minimum tolerance or safety zones for dredging in state pipeline safety program evaluation guidelines. (P-21-020) (See section 2.4.3) The NTSB is vitally interested in these recommendations because they are designed to prevent accidents and save lives.
