Dewberry Project # 50o64927
Dear Mr. Berry:
Dewberry Engineers Inc. (Dewberry) is providing this letter and attachment for the Engineer's
Certification for the above referenced project. With completion of the improvements permitted by the
above referenced Authorization to Construct, the Berryhill Elementary School WWTP now has a
permitted capacity of .008 MGD as authorized by NPDES Permit No. NCo028711. The updated effluent
limits and monitoring requirements approved in the NPDES permit modification (April 11, 2012) will
become effective with this Engineer's Certification.
The attached Engineer's Certification notes three minor changes from those approved by the
Authorization to Construct. Two tube chlorination and dechlorination tablet feed systems were installed
instead of the three tube chlorination and dechlorination tablet feed systems that were approved.
Additionally, a submersible pump was provided in the sludge holding tank instead of the submersible
grinder pump which was approved. These changes should not impact the performance of the WWTP.
Should you have any questions or comments concerning this submittal, please do not hesitate to call me at
[phone] or email me at mwestla�dewberry.com.
Sincerely,
Dewberry Engineers Inc.
