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 C ondition 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 non-biological 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 treat ment of industrial wastewater. The Permittee shall treat and process Class A non-biological residuals in a manner as not to meet the definition of “Biological Residuals” as defined in 15A NCAC 02T .1102(6). 6. Monitoring frequencies are based on the actual dry tons applied per year using the table below unless specified above. Dry Tons Applied (metric tons) Dry Tons Applied (short tons per year) Monitoring Frequency (15A NCAC 02T .1111(c)) < 290 < 319 Once per year (Annually) ≥ 290 to < 1,500 ≥ 319 to < 1,650 Once per quarter (4 x Year) ≥ 1,500 to < 15,000 ≥ 1,650 to < 16,500 Once per 60 days (6 x Year) ≥ 15,000 ≥ 16,500 Once per month (12 x Year) 7. The Permittee has demonstrated that these biological residuals, generated by a wastewater treatment facility treating industrial wastewater only, 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 and Fecal Coliform Concentrations remain less than 1,000 MPN per dry gram of residuals. 8. Williams WTP residuals are mixed, dried, and processed at the Brown WTP in Durham. 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.
