Changes to Your Previous Permit. The Division has revised your effluent limits and monitoring
conditions to reflect updated basinwide permitting guideline for the nutrient -sensitive Neuse River. From
your application and correspondence, the Division notes that you have not yet completed upgrades to your
existing WWTP as permitted by Authorization to Construct Permit 025712ACB. Therefore, this renewal
includes no other significant changes to your previous permit.
If any parts, measurement frequencies, or sampling requirements contained in this permit are unacceptable,
you have the right to an adjudicatory hearing upon written request within thirty (30) days after receiving this
letter. Your request must be in the form of a written petition conforming to Chapter 150B of the North
Carolina General Statutes, and must be filed with the office of Administrative Hearings, 6714 Mail Service

1
located on Highway 123, North of Hookerton, Greene County and,
2. upon completion of construction, pursuant to Authorization to Construct 025712ACB,
operate a 0.060 MGD Duckweed Treatment System at the same location consisting of:
• influent bar screen
• influent lagoon with pump station at overflow
• Duckweed Treatment System - twelve concrete basins (each 30' x 100'
x 4' deep), supernatant and recycle pumps, duckweed collection
troughs, waste pump, and chiller
• effluent polishing filter
• two -bank UV disinfection system
• effluent / stormwater pump station
• effluent end -pipe diffuser; and,

level TRC is currently difficult to quantify in a wastewater matrix, the Division shall consider all effluent
TRC values reported below 50 AWL to be "in compliance" with the permit. However, the Permittee shall

A. (4) CALCULATION OF TOTAL NITROGEN LOADS
a. The Permittee shall calculate monthly and annual TN Loads as follows:
i. Monthly TN Load (lb/mo) = TN .x TMF x 8.34
where:
TMF
TN = the average Total Nitrogen concentration (mg/L) of the
composite samples collected during the month
= the Total Monthly Flow of wastewater discharged during the
month (MG/mo)
8.34 = conversion factor, from (mg/L x MG) to pounds
ii. Annual TN Load (lb/yr) = Sum of the 12 Monthly TN Loads for the calendar year
b. The Permittee shall report monthly Total Nitrogen results (mg/L and lb/mo) in the discharge
monitoring report for that month and shall report each year's annual results (lb/yr) in the December
report for that year.
