Permittee shall take immediate corrective actions including those actions that may be
required by the Division of Water Quality (Division), such as the construction of
additional or replacement wastewater treatment and disposal facilities.
14. Public access to the irrigation sites shall be controlled during active site use. Such

charge (ORC) and one or more certified operator(s) to be backup ORC(s) of the
facilities in accordance with 15A NCAC 8G .0201. The Permittee shall submit the
ORC and back-up ORC designations to the WPCSOCC at least 60 days prior to the
introduction of waste into the system. The designated ORC shall visit the facilities in
accordance with 15A NCAC 8G .0204 and shall comply with all other conditions
specified in these rules.

The maximum allowable treated effluent disposed has been reduced by the amount of
direct rainfall into the storage basin (approximately 28 acre surface area) in the
following manner. First the net rainfall into the storage basin is calculated:
80% percentile annual Rainfall (Southport, NC) = 63.38 inches/year
- Pan Evaporation out of Basin (Lumberton, NQ = - 41.06 inches/year
Net Rainfall — PAN Evap. In/out of Basin = 22.32 inches/year
The net rainfall into the 28-acre storage basin generates the following additional
volume of water per year, which must be irrigated:
22.32 inches/year over 28 acre basin = 16,970,000 gallons/year
= 16.970 MG/year
The maximum allowable treated effluent disposed at the drip irrigation facility is
reduced by the amount of net rainfall into the storage basin:
Total Maximum Yearly Irrigation Allowed = 671.063 MG/yr
(Direct Rainfall - PAN Evaporation in/out of Basin) =-16.970 M_G/yr
Total Maximum Allowable Effluent Disposed = 654.093 MG/yr
= 1.792 MGD (annual averaged)
The following table breaks the irrigation out by zone, and the wastewater shall be
applied to the following zones shall not exceed the maximum irrigation rates
