Review Comments
July 23, 2003
General
Based on the A/E's certification in the Permit Application that all 15A NCAC 2H .0200
requirements regarding gravity sewers and force mains, and the Division of Water Quality's
Gravity Sewer Minimum Design Criteria adopted February 12, 1996 have been met, a review
of these items has not been performed. It shall be the permittee's• responsibility to ensure the
plans and specifications meet the appropriate design criteria and rules. Final approval of these
documents will not imply approval of any variance from these criteria unless specifically
requested and granted. Failure to comply may result in penalties in accordance with North
Carolina General Statute 143-215.6A — 143-215.6C, construction of additional facilities, and/or
referral of the N.C. Professional Engineer to the licensing board.
2. Application Parts 1II.2 & 3. appear to indicate a total of 57 lots. The plans only show 23. Only
current flows can be permitted. Therefore the flow to be permitted will be based on the 23
single family lots shown on the plans (4,370 gpd). A permit modification must be requested
before any additional connections can be made to this system.
3. The downstream sewer analysis indicates that the 10-inch gravity line immediately
downstream of this project will be flowing approximately 97% full at peak flow. Further
evaluation of this line and possible upgrade will be necessary prior to any additional flow being
approved which will be tributary to this line.
4. The A/E's computer model is apparently based on SDR 21 PVC pipe. The plans call for SDR
13.5 PVC pipe. This change reduces the pump output by approximately 1/3. While the pumps
will still function, they are operating much closer to shutoff head. Additional connections
beyond the 57 modeled for this area could result in some of these pumps failing to operate as
designed. If future additions are expected on this forcemain, the pump selection should be
evaluated and revised as necessary.
5. In order to effectively evaluate this application the applicant will need to provide
documentation that the collected flow from this additional discharge will be effectively
conveyed to the receiving WWTP without resulting in SSO's. Conditions of Pressure Sewer
Permit require the permit holder to "properly operate and maintain the system". This office
requests that a review be made of the receiving lines associated with this application as it
relates to SSO's to determine if this flow will be tributary to lines identified as reoccurring
overflow Iines. These reoccurring overflow lines have been identified as 1) Old Vermillion
Drive, 2) Lansbury Court, 3) Andover Drive, 4) Old Dowd Road, 5) Plott Road, and 6)
Vernon Drive. Please submit this information regarding the relationship of the application
flows to the lines listed above.
Specifications
1. The plan details must show the dimensions of the required ballast concrete.

Plans
1. Sheet 2 of 6
a. The forcemain should be brought into the manhole at the base to minimize splashing
and odor release.
b. Note 10. — The leakage within the 100 foot radius of the wells shall be zero.
