Re: NPDES 2022 Annual Report
Raleigh -Durham Airport Authority
NPDES Permit No. NCS000588
To Whom It May Concern:
Also sent via email
The Raleigh -Durham Airport Authority (Authority) respectfully submits an original and one copy of the
calendar year 2022 (CY2022) Annual Report, in accordance with NPDES Permit No. NCS000588 (Permit).
The current NPDES Permit (Permit), referenced above, for the Raleigh -Durham International Airport (RDU)
is dated May 12, 2017. A permit renewal application was submitted to the NCDEQ Division of Energy,
Mineral, and Land Resources (DEMLR) via certified mail as well as emailed to Brianna Young
(Brianna.Youna(&ncdenr.aov) on September 21, 2022. The Authority's understanding is that review of the
submitted permit renewal application will occur sometime in the fourth quarter CY2023. Until a new NPDES
permit is received, the Authority and its Co-Permittees will continue operating under the expired Permit.
As part of the Permit renewal application process, stormwater samples were collected on January 25, 2022
at Outfalls 001, 002, 003, 004, and 016 for analysis of Benzene, Toluene, Ethylbenzene, and total Xylenes
(BTEX), Total Nitrogen, Total Phosphorus, Oil & Grease, and Total Suspended Solids (TSS). Samples were
also collected for Detergents (MBAS) at 001, 002, 003, 004, and 007. Discharge Monitoring Reports
(DMRs) were submitted in January 2022.
On March 16, 2022, samples were collected for Acute Toxicity and Propylene Glycol analysis at Outfalls
001, 003, 004, and 007. DMRs were submitted in March 2022. Additionally, an Acute Toxicity report was
submitted to the NCDEQ Division of Water Resources Environmental Sciences Section via certified mail.
Prior to 2022, stormwater sampling was reduced to once per permit cycle for all stormwater locations.
Since sampling is required once per permit cycle, no additional samples have been collected.
