Re: NPDES 2012 Annual Report
Raleigh-Durham Airport Authority
NPDES Permit No. NCO084514
To Whom It May Concern:
The Raleigh-Durham Airport Authority ("Authority") respectfully submits an original and one
copy of the calendar year 2012 ("CY2012") Annual Report, in accordance with NPDES Permit
No. NC0084514. The Authority submitted a permit renewal application on August 30, 2012. A
draft permit has not yet been received.
Enclosed are the visual monitoring reports, total glycol and urea usage data, and nitrogen loading
information for CY2012. The Authority no longer uses urea for deicing purposes. As of June
2012, all urea purchased by the Authority was returned to the vendor. To the Authority's
knowledge, no other Co-Permittee's and airport tenants use or store urea for deicing.
If you have any questions, please contact me by phone at [phone], or by e-mail at
[e-mail].

1. Only months with glycol and/or urea usage are reported.
2. Numbers reported are in gallons and only for amount of glycol used.
3. Type IV glycol used for anti -icing is reported in gallons and at 100% (no water added).
4. Urea is reported in gallons and pounds for convenience [urea lbs.*gallons conversion (0.1198)*specific
