NTL 2007-G01 - Shallow Hazards Program - February 15, 2007

This Notice to Lessees and Operators and Pipeline Right-of-way Holders (NTL) is issued pursuant to 30 CFR 250.103 and supersedes NTL No. 98-20, dated September 15, 1998. It provides guidelines for using 3-D data and information instead of high-resolution data in water depths greater than 200 meters (656 feet), using the multichannel medium to acquire 2-D highresolution survey data and processing it, submitting shallow hazards survey reports in digital format, moving vessels near pipelines, and using a state-of-the-art navigation system to depict potential hazards. This NTL also makes some technical amendments and updates cited regulatory authorities.
