SUBJECT: Approval to perform timed composite sampling
Permit No. NC0042358
Adams Apple Condominiums WWTP
Avery County

Dear Permittee:

The Adams Apple Condominiums wastewater treatment plant is granted permission to perform constant
time/constant volume composite sampling as defined in 15A NCAC 02B .0503 (4)(d) for permit reporting
requirements in lieu of flow-proportional sampling as requested. This permission is allowable because this facility
has a design flow less than 30,000 gallons/day and under that condition according to 15A NCAC 02B .0505
(c)(3)(B): The Director may specify the methods of sample collection as to type of sample and type of composite
sampling required.

This approval is contingent upon your composite sampling consisting of aliquots of at least 100ml collected with
intervals not to exceed 20 minutes between aliquots. The Division reserves the right to change the method of
composite sampling again if we find reason to believe that this timed composite method is not producing
representative samples.
If you should have any questions, please do not hesitate to contact Daniel Boss with the Water Quality
Regional Operations Section in the Asheville Regional Office at 828-296-4500.

Sincerely,

G. Landon Davidson, P.G., Regional Supervisor
Water Quality Regional Operations Section
Asheville Regional Office
Division of Water Resources, NCDEQ
