9. The Permittee shall not distribute industrial pretreatment residuals that have a sodium adsorption ratio
(SAR) of 10 or higher without prior written Division approval. The Permittee may seek approval by
demonstrating that the entity accepting the residuals is: aware of the effects of a high SAR content;
has agreed on proper residual application rates; and has agreed to operational considerations to ensure
that the high SAR content will not adversely impact the receiving sites. Recommendations regarding
sodium application rate, soil amendments (e.g., gypsum, etc.) or a mechanism for maintaining site
integrity and conditions conducive to crop growth, can be obtained from the local Cooperative
Extension Office, the Department of Agriculture and Consumer Services, the Natural Resource
Conservation Service, a North Carolina Licensed Soil Scientist, or an agronomist.
III. OPERATION AND MA NTENANCE REQUIREMENTS
1. The residuals management program shall be properly maintained and operated at all times. The
program shall be effectively maintained and operated as a non -discharge system to prevent any
contravention of surface water or groundwater standards.

residuals gathered during a particular sampling event. The sampling plan shall account for
any foreseen fluctuations in residuals quality and indicate the most limiting times for
residuals to meet pathogen and vector attraction reduction requirements (e.g. facilities that
land apply multiple times per year but have an annual sampling frequency, may need to
sample during winter months when pathogen reduction is most likely to be negatively
affected by cold temperatures).
3. Upon the Water Pollution Control System Operators Certification Commission's (WPCSOCC)
classification of the facility, the Permittee shall designate and employ a certified operator in
responsible charge (ORC) and one or more certified operators as back-up ORCs in accordance with
