Subject: RE: PTIA NW Taxiway Connector
Richard,
I reviewed the documents submitted and there's just a few little things that need to be clarified.
The plans clearly show the temporary impacts for dewatering and your cover letter acknowledges them, but I
don't see the length of temporary impacts specified on the front sheet impact table or on the plan of the pipe on
PD -3. We have added the length of temporary impacts to the front sheet impact table.
Sheet PD -3 indicates temporary buffer impacts below the culvert but none above the culvert. However the
restoration plan shows restoration of the buffer areas to be above and below the culvert. Can you check this and
if there are no proposed impacts above the pipe please specify how the temporary dewatering will be installed
without disturbance to the buffer. Proposed temporary impacts to the stream and buffer areas have now been
highlighted on sheet PD -3 with the values added to the impact table on the front sheet. The temporary
dewatering would have a minor disturbance in the buffer and that is being accounted for.
Thanks very much for the detailed attention to my comments and for the revised plan which further limits impacts to the
buffers for S&EC measures and addresses my concern about hydrology to the "surviving" wetland.
I want to wait and check with David to see if he received any comments during the public notice before I issue an
approval, if he received significant comments then I may ask for your response to those before I issue an approval. I'll be
on holiday leave starting 12/23 and back onl/4.
Thanks,

DAYS FOLLOWING COMPLETION OF CONSTRUCTION.
14. ONCE PERMANENT VEGETATION HAS BEEN ESTABLISHED AND ACCEPTED BY THE NORTH CAROLINA
DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES (NCDENR) THE CONTRACTOR SHALL REMOVE
THE TEMPORARY EROSION CONTROL DEVICES, RE -GRADE, AND RESEED AS NECESSARY. ALL STAGING
AREAS AND HAUL ROUTES SHALL BE RESEEDED.
15. CONTRACTOR SHALL RESTORE ALL TEMPORARY IMPACT AREAS WITHIN THE BUFFER AREAS AND STREAM
TO PRE -CONSTRUCTION CONDITIONS PRIOR TO THE COMPLETION OF THE PROJECT.
