The Division of Water Quality (DWQ) has reviewed the Storm Water Management Plan dated July 24,
2006 and subsequent revisions received August 4, 2006 prepared by your engineer, Mr. Jeremy Finch,
P.E., of John R. McAdams Company, Inc. This Plan partially satisfies the stormwater conditions required
by the Individual Water Quality Certification issued on May 9, 2006. You are required to meet the
following conditions:
1. The storm water treatment system, which includes the extended detention pond, preformed scour
holes, and forested filter strips, as approved by this Office, and the drainage patterns depicted on
the plan sheets, must be maintained in perpetuity. No changes to the structural storm water
practices shall be made without written authorization from the Division of Water Quality. The
storm water easements shall allow for the ability to maintain the structures, perform corrective
actions, and shall provide protection of the structures from potential' alternations by future
property owners.
2. You must submit three (3) copies of an executed Declaration of Covenants and Restrictions-
Riparian Areas document within thirty (30) days of recording with the Register of Deeds,
Chatham County, North Carolina.
You must submit the remainder of the stormwater management plans for Phase I within the next
sixty (60) days for approval by DWQ. This final stormwater management plan (including a
signed and notarized Operation and Maintenance Agreement) will include plans and
specifications for stormwater management facilities that are appropriate for surface waters
classified as "Nutrient Sensitive Waters" (NSW). As such, they shall be designed to remove
nitrogen and remove at least 85% TSS.
4. The applicant and/or authorized agent shall contact the DWQ Express Review Program in writing
at the letterhead address within ten (10) days of the commencement of construction.
