Detailed Description of Variance Request
The variance requested is the requirement of 36 inches minimum vertical clearance from final earth
grade 15A NCAC 02T .0305 (f).
Detailed Description of why the project cannot comply
A portion of the 2" force main was inadvertently laid meeting the NC Plumbing code in leu of the 15A
NCAC 02T Minimum Design Criteria for the permitting of Pump Stations and Force Mains. The force
main was raised to meet minimum separation from a storm line thus decreasing the available cover
from final grade. While evaluating the as -built information, the area in question had asphalt installed
and is not accessible to lower.
Detailed Description of how the alternate design will meet the requirements of
15A NCAC 02T .0105(n)
The alternate design will provide the following:
(1) equal or better treatment of the waste — the wastewater was designed to be treated by the
City of Burlington's public treatment plant and will continue to do so. Therefore, the
treatment of the waste is equal.
(2) equal or better protection of the waters of the state — the 2" force main will not be subject to
any adverse traffic loading due to decreased burial depth (as calculated in the following
information). Therefore, the proposed design will provide equal protection to the waters
of the state.
(3) no increased potential for nuisance conditions from noise, odor or vermin - the 2" force main
will not be subject to any adverse traffic loading due to decreased burial depth (as
calculated in the following information). Therefore, the proposed design will not increase
the potential for nuisance conditions from noise, odor or vermin.
