Permit Modification — Additional Information
Synagro LLC DCAR
Dear Mr. Thornburg:
Regarding the additional information request of March 4, 2024 for the modification request of
the Synagro LLC Permit No. WQ0035207, please see the following response.
• The discrepancy in the request to increase the Siler City Dry Tonnage to 1,000 Dry
Tons from 250 Dry Tons, was a typo. It is correct Siler City is currently permitted for
125 Dry Tons.
• Regarding the marketability stamen for the Kerr Lake WTP was revised for
clarification and is attached below.
• Regarding the Spill Control Plan issues, the Spill Control plan has been updated to
ensure all contact information for the regional offices are including in a more efficient
manner.
• Regarding the missing pages of the RSC form for both sources, it was a scanning
error, so those missing pages are attached.
• Regarding the Siler City WTP SAR and PAN calculations that was a typo in the RSC
form my calculations were the same. Those calculations are attached as well. Along
with a updated RSC page 4.
• Regarding the TCLP results being three years old, the plant experienced some issues
with the lab when Synagro requested a new TCLP. Therefore, I used the 2020 results
from the previous sample that was taken that was used for the different contractors
permit to land apply there material. They state their processes have not changed and
that the material is the same as this previous sample. In the permit with Granville
Farms where the Kerr Lake WTP is a source, the TCLP is needed once per permit
cycle so that is why the latest one took was 2020 as well.
• Regarding the sampling plan for the Kerr Lake WTP, it has been updated to represent
the Kerr Lake WTP. Regarding the TCLP sampling frequency, with the material being
consistent and the previous permitted cycle for their land application was once per
cycle I requested once per cycle.

DCAR Marketability Statement
Kerr Lake Water Treatment Plant
Residuals will be given to local farmers for crop or grass production. Synagro will land apply material for
the local farmers who choose to receive residuals. The spreaders will be able to spread the material in
an even and consistent manner. The material is going to be land applied on fields that have grass
growing on them that are going to either be grazed or cut for hay for animal feed some fields may be in
row crop production and rates will be determined by RYE for the crop that is going to be grown for
animal consumption. An estimated 1,000 dry tons will be land applied from the Kerr Lake Water
Treatment Plant.

SPILL RESPONSE PLAN
PROJECT: SYNAGRO CENTRAL Permit W00035207
IN THE UNLIKELY EVENT OF A SPILL THE FOLLOWING ACTIONS SHALL BE
TAKEN IMMEDIATELY:
1. MANAGEMENT OF SPILL CLEAN-UP ACTIVITIES:
The Operations Manager shall take immediate charge and initiate clean-up activities. Synagro
labor and equipment is to be utilized. In the event additional labor and equipment is required,
assistance may be requested from the Town of Pittsboro, City of Dunn, Town of Franklin,
Brunswick County NC, City of Reidsville, Piedmont Regional Water Authority, Town of
Mooresville, The City of Durham, The City of Greensboro, Town of Mooresville, City of
Charlotte, International Textile Group, Town of Albemarle, or the NC Department of
Transportation, and other private contractors as necessary.
2. HALT THE SOURCE OF THE SPILL:
Such as a ruptured container or damaged transport unit.
3. CONTAIN THE SPILL:
Form a barrier. Sufficient quantities of straw shall be used for such purposes. Earthen barriers
may be constructed to augment the straw bale containment area of the spill. The Operations
Manager or the person in charge on the spill site will advise the clean-up personnel where to get
the straw, lime, and other items necessary to complete the clean-up operation, i.e., local farmers,
farm supply centers, nurseries, etc.
4. CLEAN-UP:
Employ front-end loaders, vacuum equipment, sludge application vehicles, and/or local septic
tank service to remove as much of the spilled material as possible. Straw and/or sand should be
scattered in the spill area to soak up the remaining material. The straw- and sand -soaked material
will be collected and removed to a disposal area approved by representatives of the state
regulatory agency.
5. FINAL CLEAN-UP:
Employ rotary brush sweeper if needed, and apply lime to the spill area upon the approval of the
clean-up efforts by the state regulatory representative. If the event occurs on private property, the
clean-up will be completed to the satisfaction of the property owner and state regulatory
representatives. The ultimate goal will be to restore the spill area to its original condition if
possible.
6. NOTIFICATION:
As soon as possible after the spill occurs, the Synagro Operations Manager or assistant will notify
the Synagro Central office, and they will then be responsible for notifying other key Synagro
personnel.

7. REPORTING:
Synagro Central personnel will notify the Raleigh regional office of the NCDEQ by telephone for
the Pittsboro WTP, Durham WTP's, Kerr Lake WTP, Siler City WTP. The Asheville regional
office at for the town of Franklin, SJWD WTP, The Wilmington Regional office for Brunswick
NW WTP, the Winston Salem Regional office for the City of Reidsville WTP, City of
Greensboro, The City of Graham, International Textile Group, and Piedmont Regional WTP, the
Mooresville Regional office for The City of Albemarle Tuckertown WTP, Town of Mooresville
WTP, and City of Charlotte Lee S. Dukes WTP the Fayetteville Regional Office for the Dunn
WTP. This will be done as soon as possible, but not more than 24 hours after, or on the next
working day following the occurrence. The Operations Manager shall provide a written report
within 48 hours of the spill to the Technical Services Manager. The report shall list all relative
information and actions taken. Synagro Central personnel will file a written report to the Raleigh,
Asheville, Wilmington, Mooresville, Winston Salem, or Fayetteville Regional office of the
NCDENR within 5 days of the occurrence. For after hours reporting the Division's emergency
number shall be called to report all incidences (800-662-7956 or 800-858-0368 or 919-733-3300)
