Okay.
You note in your testimony, Mr. Obermeyer, a particular change related to the guidelines for crude oil tankers over 40,000 dead-weight tonnes. Are there particular national standards related to what types of changes are applied? Or is there local flexibility, depending on a particular pilotage authority, to make these changes? What factors are they dependent upon?
I guess what I'm driving at is whether or not there are certain matters that could be based on a national floor for a standard, or whether or not flexibility based on local conditions is most desirable for pilotage authorities.
