It appears that the StormTech chambers are being proposed to support an
underground infiltration system. This is an acceptable approach to managing
the stormwater from this site. However, the Division will need additional
information to review the system and determine if state design standards have
been met. Please provide the following:
a. Full -sized plan sheets showing the entire site with its storm drainage system,
including every inlet, outlet and conveyance device. Please show how
stormwater management requirements have been met at every
proposed outlet location.
b. Please provide an Infiltration System Supplement Form with all required
items for the StormTech system (see
http: / /portal.ncdenr.org /web /wq /ws /su /bmp- manual).
c. Sealed, signed and dated supporting calculations for each BMP.
d. An original signed and notarized O &M Agreement form. Sample O &M
forms are available at: http: / /portal.ncdenr.org /web /wq /ws /su /bmp-
manual.
e. A soils report that states the level of the SHWT elevation based on a boring
within the footprint of each of the proposed BMPs.
