I have a question about how to log 2 benchmarks. they are hy2196 and hy2211. hy2196 has been shortened to 300 ft from it original 1103 foot height, so would it be found? hy2211 was removed in the early 1980's and replaced by an 1100 foot stack. the original stack was shortened to below the height of the top og the plant and can only be seen if permited access to the facility, so would this be logged as destroyed?
