RE: Town of Pittsboro Wastewater Treatment Plant- Permit Number NC0020354
Dear Ms Thedford:
We are respectfully requesting permit renewal for the Town of Pittsboro's wastewater treatment plant permit number
NCoo2o354. The permit renewal application was due in October 30th 2015.
In 2010 the Town of Pittsboro began a wet weather flow improvements project at the Towns wastewater treatment plant. The
project consisted of the construction of two new 330,000-gallon equalization/storage basins. Other improvements included three
Return Activated Sludge Pumps (RAS)providing return sludge flow to the biological treatment units. Also included in the
upgrade was a new UV disinfection system and channel to replace our older units.
The Town of Pittsboro's Biosolids are removed from the treatment process daily. Sludge is thickened using a rotary drum
thickener and sent to two(2)aerobic digesters. Biosolids are then stabilized and land applied to several permitted sites by
Synagro,our contracted biosolids management company. Synagro is contracted to handle all permitting, sampling and lab
analysis as well as the ORC requirements for the Town of Pittsboro. Approximately 100 dry tons of biosolids are applied
annually.
Other changes in the permit renewal include a change in plant treatment capacity to increase from .75 mgd to 1.249 pending
plant expansion. We also have future allocation to Haw River pipe 002 for 3.47 mgd pending future construction and expansion.
Sincerely,
Bryan Gruesbeck, ICMA-CM
Town Manager

Briefly explain any steps underway or planned to minimize inflow and infiltration.
The Town of Pittsboro has an extensive ongoing I/I program to reduce the storm flow. The repairs and replacements
began in 2002 and continue today and have paid off in reducing the non-wastewater flows. Stimulus money
applications as well as other grants are consistently applied for in hopes of getting real assistance to finish the job.
B.2. Topographic Map. Attach to this application a topographic map of the area extending at least one mile beyond facility property boundaries. This
map must show the outline of the facility and the following information. (You may submit more than one map if one map does not show the entire
