1. Maximum Dry Tons per Year is the quantity of residuals approved for land application from each permitted facility.
2. Analyses to demonstrate that the residuals are non-hazardous (i.e., TCLP, ignitability, reactivity, and corrosivity) as stipulated under permit Condition IV.2.
3. Testing of metals and nutrients as stipulated under permit Condition IV.3.
4. Analyses of the pathogen and vector attraction reductions as stipulated under permit Condition IV.4.
5. Class A water treatment plant residuals are exempt from meeting the pathogen and vector attraction reduction requirements in Condition IV.4, provided the Permittee does not mix them with
residuals generated during the treatment of domestic wastewater, the treatment of animal processing wastewater, or the biological treatment of industrial wastewater. The Permittee shall treat and
process Class A water treatment plant residuals in a manner as not to meet the definition of “Biological Residuals” as defined in 15A NCAC 02T .1102(6).
6. Residuals are generated during the biological treatment of industrial wastewater with an estimated 1% domestic waste stream contributio n and meet the definition of “Biological Residuals” as
defined in 15A NCAC 02T .1102(6). However, the Permittee has demonstrated that the residuals are pathogen free and are not required to monitor for Vector Attraction Reduction pursuant to 15A
NCAC 02T .1107(c) provided that no significant odor complaints or problems with vector attraction are encountered at the land application site and Fecal Coliform concentrations remain less than
1,000 MPN per dry gram of residuals.
7. Monitoring frequencies are based on the actual dry tons applied per year using the table below unless specified above.

The Division shall not require sampling if no land application events occur during the required sampling period. The annual report shall include an explanation for missing sampling data.
The United States Environmental Protection Agency (US EPA) may require Permittees that submit annual reports to their agency to make up the missed sampling. Contact the US EPA for
additional information.
