C. 27626-0535 fV�, d,Sow Loaic/ RE: WWTP for Country Wood Subdivision Permit # NCO065684 U "%off CC�3►-e'j "As Built" Certification Dear Mr. McIntire; In reference to the above noted waste water treatment plant, and the permit requirement for an Engineer's "Certification of Construction Compliance" I have made the following investigations. 1.) Reviewed a plan prepared by Mr. Robert E. Etue, 2.) Reviewed the design plan as submitted, and approved by your office, 3.) Visited the site for my own inspection, and 4.) Met with the WWTP Operators (Mid South) The Etue plan is an "As Built" survey which has been certified as accurate by Mr. Etue; who is a Registered Professional Engineer in North Carolina. With the "As Built" certification as a reference I did not re -measure the structures; but rather used my field visit to visually verify the general configuration of the components and operability of the system. I have also been informed that the treatment plant operators ( Mid South Water Systems, Inc. ) have reviewed the system, and performed start-up tests on the system's mechanical components. The Mid South operators, while noting some details that they wish to have changed, are prepared to accept the plant for operation. My research and observation indicate to me that the constructed system; due to field encountered complexities; has been constructed differently from the approved plan. The system, however, has the same components and the same treatment process as that which was approved by your office. I believe that the system; as constructed; is substantially in compliance with the original "approved" design plans. I am hereby certifying that this WWTP has been constructed in an appropriate manor and is basically ready for operation. If you should have any information that I should be aware of, or if you should have any questions, please give me a call. �o 0wII18110B�ss Sincerely; %% A ie ®e�� p� FAA � O r ter" 7WO �as John W.

This Authoriztion to Construct requires that all components of the above described wastewater treatment facility be at least 50 feet from the facility's property line. Also, as a condition of this Authorization to Construct, in addition to the berm specified on the plans a wood fence and vegetative buffer shall be constructed and should be verified by the engineer prior to submission of the Engineering Certification. This Authorization to Construct is issued in accordance with Part III, Paragraph A of NPDES Permit No. NCO065684 issued November 14, 1994, and shall be subject to revocation unless the wastewater treatment facilities are constructed in accordance with the conditions and limitations specified in Permit No. NC0065684. The sludge generated from these treatment facilities must be disposed of in accordance with G.S. 143-215.1 and in a manner approved by the North Carolina Division of Water Quality. In the event that the facilities fail to perform satisfactorily, including the creation of nuisance conditions, the Permittee shall take immediate corrective action, including those as may be required by this Division, such as the construction of additional or replacement wastewater treatment or disposal facilities. The Mooresville Regional Office, telephone number (704) 663-1699, shall be notified at least forty-eight (48) hours in advance of operation of the installed facilities so that an in -place inspection can be made.
