COMPOST PERMIT
In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North
Carolina as amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
Sun Shares
Durham County
FOR THE
operation of a sludge composting pilot study consisting of windrowing sludge generated from the
City of Durham's Northside wastewater treatment facility with mixed paper waste (as described in
Condition II -7) and later land applied at the North Carolina State University's Demonstration
Forest Lands located near Rougemont adjacent to U.S. 15-501 in Durham County to serve Sun
Shares with no discharge of wastes to the surface waters, pursuant to the application received May
21, 1991 and in conformity with the project plan, specifications, and other supporting data
subsequently filed and approved by the Department of Environment, Health and Natural Resources
and considered a part of this permit.
This permit shall be effective from the date of issuance until June 30, 1992, and shall be
subject to the following specified conditions and limitations:
1. PERFORMANCE STANDARDS
1. This permit shall become voidable in the event of failure of the sludge composting facility
to adequately protect the assigned water quality standards of the surface waters and
groundwaters.
2. The sludge composting program shall be effectively maintained and operated as a
non -discharge system to prevent discharge of any wastes resulting from the operation of
this program.
3. The issuance of this permit shall not relieve the Permittee of the responsibility for damages
to surface or groundwaters resulting from the operation of this facility.
4. In the event that the sludge composting program is not operated satisfactorily, including the
creation of nuisance conditions, the Permittee shall take such immediate corrective action as
may be required by this Department, including the construction of additional or replacement
wastewater treatment or disposal facilities.
5, Diversion or bypassing of the untreated sludge or compost drainage wastewater from the
compost facilities is prohibited.

6. Compost sludge should not be used in areas of intense public use (schools, playgrounds,
etc.).
11. OPERATION AND MAINTENANCE REQUIREMENTS
1. The facilities and disposal sites shall be properly maintained and operated at all times.
2. The sludge composting operation must be conducted under the supervision of the certified
wastewater treatment plant operator required by the Certification Commission for operation
of Sun Shares sludge composting pilot study.
3. Only sludge generated by the City of Durham's Northside wastewater treatment facility
shall be used in this pilot study.
4. The sludge compost pilot study shall be conducted at the City of Durham's Northside
wastewater treatment facility.
5. Any leachate generated during this pilot study will be disposed of at the City of Durham's
Northside wastewater treatment facility.
6. The composting shall be done using the windrow method and shall attain a temperature of
550 C or greater for at least 15 days during the composting period. During the high
temperature period there will be a minimum of five turnings.
7. The compost pilot study shall be conducted using three batches of different sludge
concentrations. The following batch constituents and concentrations are approved for the
study:
Batch
Sludge (dry tons)
MIxed Paper Waste (dry tons
Total Per Batch
Batch I
2.4 Dry Tons
5.6 Dry Tons
8 Dry Tons
Batch II

3.2 Dry Tons
8 Dry Tons
Total
10.8 Dry Tons
13.2 Dry Tons
24 Dry Tons
8. The final product shall be land applied on slopes of less than 6 percent.
9. The following buffers zones shall be maintained:
a) 400 feet from residences under separate ownership for surface application
method; however, the buffer zone requirement may be reduced to a minimum of
100 feet upon written consent of the owner,
b) 100 feet from "SA and SB" classified waters and public surface water supplies
for both methods,
c) 100 feet from "WS" classified waters and other streams, creeks, lakes, rivers
and surface water drainage ways for surface application method,
d) 100 feet from property lines for both methods; however, this requirement may
be reduced upon written concurrence from the adjoining property owner,
e) 50 feet from public right of ways for surface application methods,
f) 10 feet from upslope interceptor drains and surface water diversions for both
methods,
g) 25 feet from downslope interceptor drains, surface water diversions,
groundwater drainage systems and surface drainage ditches for both methods

Division.
3. The Permittee shall monitor the temperature of the windrows during composting. The
temperature shall be measured at sufficient depths of the windrow and along the length of
the windrow such that a representative temperature profile can be created. The temperature
profiles shall consist of a depth and length profile as well as a time temperature profile for
the batch.
4. The Permittee shall supply monitoring records of temperature and compost age or pathogen
testing sufficient to adequately attest that the product meets the requirements of the Process
to Further Reduce Pathogens.
5. Prior to final disposal of the compost the Permittee shall submit the information necessary
