(OP)
Developing weld procedure for sour service ASME Sec VIII-Div.1 Plate used for the test is SA-516-70 - SA-516-60 dual certified 3/8" thick. Process is FCAW. HAZ & Weld metal are passing with no issues. Base metal is failing @ -50F. Question I have is base metal Charpy Impact Testing required as-per ASME Sec VIII.Div.1.

I concur with metengr, 3/8" plate will not be normalized unless you ask for it. Normalized condition is necessary to have a prospect of passing BM impacts at -50F.

For example: SA-516-70N Heads/Shell, SA-333-Gr.6 Piping, SA-350-LF2 Flanges. All are exempt from impact testing (by you) to -50F. Then substitute the WPS wire for an impacted tested wire as per UCS-67(a)(3).
With the above an impact tested procedure is not required. Of course this may all mean nothing if the customer requires a WPS that was impact tested.
