A. Application:
1. The provided Residuals Source Certification (RSC) is for 2,817 dry tons per year generated from
Davie County Cooleemee WWTP. This value includes increased dry tonnage required to cleanout
a damaged holding basin. The revised Land Application Site Certification (LASC) is for 179.7
acres (nearly 200 acres less than what was certified when the increase to the RSC was approved
and permitted July 2, 2021). This combined with the most recent laboratory analysis collected on
08/10/2021 results in minimum acreage values that exceed the acreages to be certified with the
revised LASC Form. Additionally, the land use and soil types for each field indicate that PAN
uptakes are less than 200 lbs/acre per the NC Realistic Yield Database. It is unclear how the Davie
County Class B program will be able to apply at agronomic rates and manage the increased dry
tonnage. Please address Section 3, Item 6 in the application which requires a plan and schedule to
resolve any known issues that would prevent land application of the proposed residuals due to the
violation of North Carolina (e.g. not enough storage, not enough land, vector reduction practices
not in place, etc.). Please also provide information regarding whether Davie County’s Cooleemee
WWTP facility is a source for another residuals permit, or whether additional land application fields
are proposed.
