Subject: Request for Additional Information
Permit No.WQ0037600
Legacy Phase 5A
Chatham County
Dear Mr. Becker:
The Division recently completed a preliminary review of the submitted final engineering certification for the
above permit. Based on the submitted record certification and as-built drawings for the subject project
(WQ0037600), it appears that there are discrepancies between the permitted and constructed project as well as
incomplete certifications for the entire project. However, no permit modification was requested for this project
and no additional certifications have been received to date.
Please submit a complete response to this office for the following items:
1. The submitted record drawings indicate that approximately 598 linear feet(LF)of 2-inch pressure sewer
was installed. Note that the permit was issued for the installation of approximately 477 LF of 2-inch
pressure sewer.As no permit modification was submitted, it is unclear to the Division why the length of
2-inch pressure sewer as installed varies from the permitted amount by approximately 20%. Please
explain the deviation from the originally permitted length of 2-inch pressure sewer line, and why the
final certification was submitted with no indication as to this deviation. [see Condition 1.7 per Permit No.
W00037600]
2. The originally permitted drawings as well as the record drawings indicate that this cul-de-sac(Part 2) is a
terminal portion of this project, requiring certification of the downstream pressure sewers prior to
operation of this section of the project per 15A NCAC 02T.0116.To date, no such certifications have
been received. Please provide these certifications as soon as possible.
3. A permit modification request with application fee must be submitted to the PERCS Unit in the Central
Office for this project. Hydraulic calculations/modeling indicating that the alterations in 2-inch pressure
sewer line length (as well as any other possible deviations to other portions of the project)do not
adversely affect the overall operation of the system will be required as well.These items should be
submitted as soon as possible.

The Division relies on the certification process to ensure that permitted facilities are constructed in accordance
with the documents that have been reviewed and approved for permit issuance. It is the Division's expectation
that the certifying professional engineer certifies that"the permitted facility has been installed in accordance
with the rules, any minimum design criteria except as noted, and approved plans and specifications."
Furthermore, it is the also Permittee's responsibility to ensure that the project has been constructed pursuant to
the applicable standards and requirements via the documentation provided by the engineer. Please note that
failure to comply with the issued permit may result in penalties in accordance with North Carolina General
Statute§143-215 6A through §143-215.6C,construction of additional or replacement wastewater collection
facilities,and/or referral of the North Carolina-licensed Professional Engineer to the licensing board.
Within 30 days of receipt of this letter, please provide a response to this letter to:
