IIl. Certification Statement:
1 10 certify to the best of my knowledge that the addition of
the volume of wastewater to W permitted in this project has been evaluated along the route to the receiving
wastewater treatment facility and that the flow from this project is not anticipated to cause any capacity
related sanitary sewer overflows or overburden any downstream pump station en route to the receiving
treatment plant under normal circumstances, given the implementation of the planned improvements
identified in the planning assessment where applicable. This analysis has been performed in accordance
with local established policies and procedures using the best available data. This certification applies to
those items listed above in Sections I and II plus all attached planning assessment addendums for which I
am the responsible party. Signature of this form certifies that the receiving collection system or treatment
works has adequate capacity to transport and treat the proposed new wastewater.

NC Dept of Environmental Quality
Raleigh Regional Office
The accompanied Fast -Track Application (FTA 04-16) is a modification to existing Permit #WQ0040504. The
modification is due to increases in pipe length of greater than 10% from what was originally permitted to what was
installed.
This modification includes 4,141 lineal feet of 8-inch gravity sewer (3,943 lineal feet of 8" PVC and 198 lineal feet of
8" DIP gravity sanitary sewer) for the proposed Davis Park Townhomes development located at the intersection of
Davis Drive and Hopson Road in Durham, NC. The sewer system will be a public system owned and operated by
Durham County. The private collection system is being permitted separately.
Existing permit #WQ0040504 includes 3,428 linear feet of 8-inch gravity sewer to serve 140 three -bedroom
townhomes.
There are currently residents in this project waiting to get Certificates of Occupancy for their homes. If there is any
way you could expedite the review process, it would be greatly appreciated.
This package includes the following:
• Fast Track Application FTA-04-16 for Permit Modification
• Flow Tracking FTSE 10-18
• Street Level and USGS Topo Map
• Developer's Operational Agreement
• Check for $480
Please do not hesitate to call me at [phone] if you have any questions.
