WP0201500087: Hirschman Water & Environment LLC Memo, November 21, 2018, document available in CV, listed

While VARlOK764 relates to HTC block C6, specifically, SWM was constructed as SWM Facility #2, permitted in 2004 (ref.
Attached). List VARlOK764 as Retention basin III (4x WO vol. with Aquatic bench) in DEQ SWCGP database, since closest
description, in my view. HTC block C6 falls into a narrow category of development covered by a constructed SWM facility
that predates 2009 state SWM permit regulations. Part IIC SWM Facility #2 covers multiple Abington Place /HTC
developments. Unclear how else to list this BMP ( reviewed multiple WPO folders for clues). Attached: 4-p. email chain [ incl.
county Engineer (G. Brooks), Engineering, Timmons ( F. Pohl) ] lends perspective —and is representative /useful.
