Wake County, NC
Dear Ms. Witherspoon:
AUG 7 2009
DENR - WATER OUALITY
WETL OM AND STORIMWATER BRANCH
On June 8, 2009, Soil & Environmental Consultants, PA submitted a response to the Notice of
Violation & Notice of Intent to Enforce (NOV-2008-SS-0033) on behalf of Toll Brothers, Inc. for
Brier Creek Country Club Phase 15-Land Bay J/M. Annette Lucas of the 401 Oversight/Express
Permitting Unit has requested additional information regarding this response. Specifically, Ms.
Lucas is requesting additional modifications to the stormwater system discharging and the rip-rap
dissipater on the west side of Sporting Club Drive.
As per her request, attached are modified Exhibits A, B, C, D & E. These exhibits indicate the
removal of junction box (JB) 12 and its replacement with a flared end section, as previously
shown in our June 8, 2009 submittal. However, the "class 2" riprap that will be placed below the
proposed flared end section will now extend all the way to the creek. In addition, as previously
shown, the existing 36 inch Re-inforced Concrete Pipe (RCP) located between JB12 & JBW 12D
will be removed (or plugged) and the existing rip-rap dissipater will incorporate additional rip-rap,
check dam pockets and a pool for energy dissipation.
We anticipate that this addresses all of the DWQ's concerns. If you have any further questions or
any additional explanation is needed, please contact me at dedwardsna sandec.com.
Sincerely,
CIL? alll?
