RE: Burlington-Alamance Airport Authority
Runway 6-24 Extension; 401/404 Permitting
TBI Reference No. 2101-0301
DWQ #OS-1711
COE Action ID No. 200320418
Dear Ms Karoly:

VYETLANDS ANA STORMWATER BRANCH
On behalf of the Burlington-Alamance Airport Authority, we hereby request clarification of certain
requirements included in the Water Quality Certification issued December 1, 2005 for the proposed
extension of Runway 6-24 at the Burlington-Alamance Regional Airport.
1. NCEEP Mitigation Pam
Paragraph 2 of the Certification calls for the mitigation payment to NCEEP to be made within
one month of the date of approval (of the 401 Water Quality Certification). This time frame is
not practical since the Corps of Engineers permit remains pending and capital funding for the
project is not in place at this time. We request an initial extension of 6 months for this payment.
It would be our expectation that payment would be required prior to the start of construction.
2. Stormwater Management Plan Submittal
Paragraph 9 of the Certification calls for the submittal to DWQ of the final, written Stormwater
Management Plan for the project within 60 days of issuance of the 401 Water Quality
Certification. We request a 6 month extension for this submittal. It would be our expectation
that Plan approval would be required prior to the start of construction.
3. Stormwater Management BMP's
Paragraph 9 of the Certification outlines Stormwater Management Plan requirements. Please
confirm our understanding that the 1999 NCDENR BMP Manual is applicable to this project and
that linear addition maybe used to combine the assumed efficiencies of BMP's implemented in
series to achieve the stipulated 85% TSS total removal efficiency. We anticipate using grassed
swales in series with extended dry detention (35% + 50% = 85%) to meet the water quality
requirements in a manner consistent with FAA Advisory Circular 150/5200-33A, "Hazardous
Wildlife Attractants on or near Airports."

4. Deed Notifications
Paragraph 8 of the Certification requires deed notifications or similar mechanisms. This project
involves construction of airport runway infrastructure on airport land. It does not involve the
creation of any lot or building site for sale or lease. The sample deed notification document on
the NCDENR website is clearly not applicable to this project. Please clarify this requirement.
Thank you for considering this matter. If you have any questions, please call.
Sincerely,
Eric M. Stumph, P.E. 7.14 ~ ~ ~ 3 ~ ~ ~ ~~
