Raleigh -Durham Airport Authority
NPDES Permit No. NCS000588
To Whom It May Concern:
The Raleigh -Durham Airport Authority (Authority) respectfully submits an original and one
copy of the calendar year 2019 (CY2019) Annual Report, in accordance with NPDES Permit No.
NCS000588 (Permit).
The current NPDES Permit, referenced above, for the Raleigh -Durham International Airport
(RDU) is dated May 12, 2017. With the receipt of this Permit, stormwater sampling was reduced
to once per permit cycle for all stormwater locations. Therefore, no stormwater samples were
collected during CY2019.
Enclosed please find the visual monitoring reports, the total glycol usage data, and pavement
deicing data for CY2019. This report was also emailed to Bethany Georgoulias with DEMLR.
If you have any questions, please do not hesitate to call me at 919-840-7741 or email me at
gina.danison(?a,rdu. com.
