Hi Alan,
Dan came back with an updated plan set showing the sills you asked about, and confirmed that the second barrel
is elevated above the wetland. Please see attached and let me know if you have any other concerns.
Thanks,
Daniel

Is the second barrel of the two barrel set at grade with the wetland? You show just the one
barrel being buried. Given that these barrels have to be buried a foot. Sills at the upper and
lower end would help hold the grade.
