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 DEMLR via certified mail as well as emailed to Brianna Young (Brianna.Young(a ncdenr.(_,,ov) on September 21, 2021. Between June 29, 2023 and January 4,2024 multiple emails were exchanged between the Authority and Brianna Young to provide additional information and clarification. A draft NPDES permit was received January 31, 2024. The Authority submitted a request for extension on comments which was granted on February 19'. Comments are due back to NCDEQ on April 8, 2024. Until a new NPDES permit is received, the Authority and its Co-Permittees will continue operating under the expired Permit as automatic authorization to discharge beyond the expiration date is granted in Part III.B.I. The Authority prohibited the use of Urea as a pavement deicer in June 2012. As part of the Permit renewal application process, stormwater samples were collected on January 25, 2021 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 2021.
