Requested modifications or variances to the Minimum Design Criteria will be reviewed on a case -by -case basis and each on its own merit. Please note that variances to the Minimum Design Criteria should be requested and approved during the permitting process prior to construction. After - construction requests are discouraged by the Division and may not be approved, thus requiring replacement or repair prior to certification & activation. 115A NCAC 02T .0116] 8. Gravity sewers installed greater than ten percent below the minimum required slope per the Division's Gravity Sewer Minimum Design Criteria shall not be acceptable and shall not be certified until corrected. If there is an unforeseen obstacle in the field where all viable solutions have been examined, a slope variance can be requested from the Division with firm supporting documentation. This shall be done through a permit modification with fee. Such variance requests will be evaluated on a case -by -case basis. Resolution of such request shall be evident prior to completing and submitting the construction certification. [ 15A NCAC 02T.0105(n)] 9.

One pump type having the same characteristics (impeller, horsepower, RPM, etc) will be installed at each pump station. This will allow them to be interchangeable between each of the pump stations. The selected pumps will meet or exceed the peak flow rate at each pump station, however, no additional flows are to be expected as a result of this project.
