DG Digest: See the significant changes to Amendment 40 of the Covid-19-delayed IMDG Code.

The last full week of the month begins with a new administration in place in Washington.  On the DG front, PHMSA will continue business as usual for now.  What impact (or not) the new political environment may have on our industry community’s specific interests remain to be seen.  The Senate is currently working on the confirmation hearings for proposed new Secretary of Transportation Pete Buttigieg.  From there, we’ll all have to wait and see what develops.  We’ll keep bringing you the latest!  In line with that, here’s the last week’s news:
