Re: Raleigh-Durham Airport Authority
NPDES Permit No. NCO084514 (Wake County)
Certification of Non -Urea Airside Pavement Deicers
Ms. Grzyb:
In accordance with 40 CFR Part 449, the Raleigh-Durham Airport Authority (Authority) does not
use airside pavement deicers containing urea. Additionally, earlier this year, the Authority
returned all urea pavement deicer to the manufacturer and does not have any on site.
If you have any further questions about the permit renewal or need additional information,
please do not hesitate to contact Gina Danison, Environmental Program Manager, at 919-840-
7741 or [e-mail].
Sincerely,
