To Whom It May Concern:

he section
The Raleigh-Durham Airport Authority ("Authority") respectfully submits an original and one
copy of the calendar year 2016 ("CY2016") Annual Report, in accordance with NPDES Permit
No. NC0084514. The Authority submitted a permit renewal application on August 30, 2012. In
mid -2015, after discussions with DEQ staff, a new permit application was requested. This
application was submitted in 2015 with a draft NPDES received from DEMLR in mid -2016. The
draft NPDES permit is now out for public comment.
Enclosed are the visual monitoring reports, the total glycol usage data, and nitrogen loading
information for CY2016. The Authority no longer uses urea for deicing purposes. To the
Authority's knowledge, no other Co-Permittee's or airport tenants use or store urea for deicing.
If you have any questions, please do not hesitate to call me at 919-840-7741 or email me at
Bina. danisongrdu. com.
Sincerely,
&Danison
Environmental Program Manager
