Good Afternoon Sue and Chris,
Please find attached updated PCN and responses to information below. Please note that 2 water line crossings (1 of
Little Alamance Creek and 1 of Beaver Creek) have been delineated by Pilot and incorporated into the PCN. Additionally,
Pilot also delineated a limited area of right of way along McConnell Road associated with the widening of McConnell
Road to add turn lanes. It was determined after Civil design that the proposed widening within this area would not
result in additional impact to streams or wetlands. Let me know of any concerns, thanks.
NCDWR 1: The plan sheet labeled Overall McConnell Ridge Stream Impacts does not appear to include all jurisdictional
features. Specifically, wetland DWE does not appear to be shown and lot/fill development appears to be proposed
which may impact this feature. Please provide an overall development plan sheet showing current and future proposed
development with all jurisdictional features shown. The Division understands that future development areas are
conceptual in nature.
Applicant Response: Please see attached Overall Drawing (Evans Sheet 1 of 9) in updated PCN. There are no future
anticipated impacts to waters outside of this application.
NCDWR 2: Please provide a stream restoration detail for the areas of temporary stream disturbance for open cut sewer
line installation.
Applicant Response: Please see attached restoration details for the proposed restoration of temporary disturbance from
the sewer lines (Evans Sheet 9 of 9) and water lines (Gannett Fleming Sheets 2/3 of 3).
NCDWR 3: Pursuant to 15A NCAC 02H.0506(b) "a 401 Water Quality Certification may only be issued upon determining
that the proposed activity will comply with state water quality standards which includes designated uses, numeric
criteria, narrative criteria and the state's antidegradation policy, as defined in rules of 15A NCAC 02B .0200... In assessing
whether the proposed activity will comply with water quality standards, the Division shall evaluate if the proposed
activity: (2) would cause or contribute to a violation of water quality standards; (3) would result in secondary or
cumulative impacts that cause or contribute to, or will cause or contribute to, a violation of water quality
standards. Based on the current proposed plan the Division believes there is potential for indirect impacts to stream SC
as all surface flow to this stream appears to be routed to a SCM which would discharge into Stream DSA. Please either,
include indirect impacts to this stream within the impact table and provide mitigation as appropriate, provide hydrologic
calculations to document that surface flow will continue to support the existing function of the stream, or provide a
monitoring plan that will document existing conditions and post construction conditions stream DSA.

Applicant Response: The applicant has designed the site to return approximately 30% of the pre -construction drainage
area to the unimpacted origin of Stream SC following construction. Initial designs were approximately 10-15% of the
pre -construction drainage aera, however, the applicant updated their stormwater management plan to discharge roof
leaders and backyards in the vicinity of the unimpacted origin of Stream SC to obtain the 30% post construction drainage
area. It should be noted that not all 70% of the drainage area that is being redirected to SCM contains impervious
surfaces. Yards, landscaped areas and other pervious aeras, which make up a considerable percentage of the removed
drainage area, will continue to provide hydration from groundwater recharge to the unimpacted origin of Stream
SC. Based on the amount of post construction drainage area and lack of all of removed drainage area being from
impervious surfaces, it is our opinion that Stream SC will continue to function as an intermittent stream channel.
Sincerely,
Bradley S. Luckey, PWS
