are required by the Division, to improve performance of the existing treatment facility. These buffers do,
however, apply to modifications of the treatment and disposal facilities which are for the purpose of
increasing the flow that is tributary to the facility. These buffers do apply to any expansion or
modification of the spray irrigation areas and apply in instances in which the sale of property would cause
any of the buffers now complied with, for the treatment and disposal facilities, to be violated. The
applicant is advised that any modifications to the existing facilities will require a permit modification.
6. Any residuals from the wastewater lagoon which are to be land applied shall be land applied at agronomic
rates as established by the North Carolina Department of Agriculture and shall meet one of the following
stabilization methods to control possible nuisance conditions:
a) the residuals are subsurfacely injected, or
b) the residuals are incorporated into the soil within 24 hours, or
c) sufficient lime is added to the residuals to create a uniform mixture and achieve a pH of 10 for thirty
minutes prior to being surface land applied.
In addition to the above, the following buffers shall be maintained for any wastewater residuals which are
to be land applied:
a) 400 feet from residences or places of public assembly under separate ownership for surface application
method; however, the buffer zone requirement may be reduced to a minimum of 100 feet upon written
consent of the owner and approval from the Washington Regional Office,
