1. Please update the level spreader- vegetated filter strip design per Chapter 8 of the BMP Manual,
available at: http: / /Portal.ncdenr.org /web /wq /ws /su /bmp- manual. The DWQ recommends that
you consider using an engineered filter strip to reduce the length of the level spreader needed
and for ease of maintenance. Please contact Annette Lucas at (919) 807 -6381 if you have any
questions about the design.
Please provide the current version of the LS -VFS Supplement Form, including the required items
checklist and any items that were omitted from the previous submittal. The Supplement Form is
available at the above web site.
3. Please seal, sign and date all plan sheets
