II. NEW AND MAJOR MODIFICATION APPLICATIONS (this section not needed for renewals or minor
modifications, skip to next section)
Description Of Waste(S) And Facilities
1. Please attach completed rating sheet. Facility Classification: Land Application of Residuals
2. Are the new treatment facilities adequate for the type of waste and disposal system?
® Yes ❑ No ❑ N/A. If no, please explain:
3. Are the new site conditions (soils, topography, depth to water table, etc) consistent with what was reported by
the soil scientist and/or Professional Engineer? ® Yes ❑ No ❑ N/A. If no, please explain:
4. Does the application (maps, plans, etc.) represent the actual site (property lines, wells, surface drainage)? ❑
Yes ® No n N/A. If no, please explain: Buffer maps for all fields, prepared by Synagroo, are accurate based
upon visual observations during the site visit on 9 August 2011.
5. Is the proposed residuals management plan adequate and/or acceptable to the Division. E Yes ❑ No n
N/A. If no, please explain:
6. Are the proposed application rates for new sites (hydraulic or nutrient) acceptable?
E Yes ❑ No ❑ N/A. If no, please explain: Based upon the request to increase residuals land application to
650 dry tons/year and based on the amount of farm land in the City of Dunn program (approx. 608 acres after
modification), there appears to be adequate resources available to manage the increase tonnage. The City of
Dunn is undergoing a major renovation at the plant and additional land application events have taken place
during the 2010 and 2011 year to remove solids from the plant to accommodate construction activities at the
facility. Based on the information provided in the 2010 Residuals Annual Report for the City of Dunn wwtp,
the volume of sludge land applied was 230 dry tons to,six fields. All fields applied to during the 2010 year had
application rates less than 50% of the allowable PAN for the given crops applied to.
7. Are the new treatment facilities or any new disposal sites located in a 100-year floodplain?
❑ Yes ® No n N/A. If yes, please attach a map showing areas of 100-year floodplain and please explain
and recommend any mitigative measures/special conditions in Part IV: The Carlton Lamm farm is adjacent to
the Cape Fear River (west bank) is within the 500 year floodplain. The Harold Eldridge farm has a small 100
year floodplain boundary within the buffer on the west side of the application fields and the Gerald Haynes
farm is well outside of the 100 year and 500 year floodplain in the central part of Harnett County.
8. Are there any buffer conflicts (new treatment facilities or new disposal sites)? n Yes or ® No. If yes, please
attach a map showing conflict areas or attach any new maps you have received from the applicant to be
incorporated into the permit:
9. Is proposed and/or existing groundwater monitoring program (number of wells, frequency of monitoring,
monitoring parameters, etc.) adequate? n Yes ❑ No ® N/A. Attach map of existing monitoring well

predominant soil types in all fields have at least one foot to the SHTW (with most having at least a three feet to
the SHWT).
The Harold Eldridge farm acreage is being corrected from an earlier application when the Eldridge farm was
added to the City of Dunn residuals land application program.
The Gerald Hayes farm fields are being transferred from the Town of Fuquay land application program that has
ceased operation. The Hayes farm is a high sand ridge with coastal bermuda pasture. Eric Thompson has
corrected the corresponding pages of the application to accurately reflect the crop being grown on the Hayes .
farm (bermuda verses fescue).
All farms visited on 9 August had cattle grazing in the proposed application fields. All fields proposed will
need to have nutrients reduced by 25% consistent with NRCS Code 590 - "A11 nitrogen -rates for hay production
are for pure grass stands. Due to the nutrient recycling by grazing animals, the planned nitrogen rate per unit
yield for hay crops shall be reduced by 25% for the portion of the expected yield that is removed through
grazing". -
