PERMISSION IS HEREBY GRANTED TO
SUN SHARES
Durham County
FOR THE
continued operation of a sludge composting pilot study consisting of windrowing sludge generated from
the City of Durham's wastewater treatment facilities with mixed paper waste and later land applied at sites
as approved by the Raleigh Regional Office to serve Sun Shares with no discharge of wastes to the surface
waters, pursuant to the amendment request received February 12, 1992 and in conformity with the project
plan, specifications, and other supporting data subsequently filed and approved by the Department of

I. 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.

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.

etc.).

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 wastewater treatment facilities shall be used
in this pilot study.
4. The sludge compost pilot study shall be conducted at the City of Durham's Northside and
Farrington Road wastewater treatment facilities.
5. Any leachate generated during this pilot study will be disposed of at the City of Durham's
Northside and Farrington Road wastewater treatment facilities.
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 final product shall be land applied on slopes of less than 6 percent.
8. The following buffer 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,

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
Processes to Further Reduce Pathogens.
5. Prior to final disposal of the compost the Permittee shall submit the information necessary
