BACKGROUND
Wastewater Treatment. This WTP facility utilizes conventional wastewater -treatment technology
[coagulation, flocculation, sedimentation, filtration and disinfection]. The Permittee draws raw water from
Sandy Creek into a flash mixer where ferric acid/sodium hydroxide are added to adjust pH. Carbon and
polymer are introduced at the flocculator prior to the sedimentation basin. Prior to filtration, the water is
chlorinated, then after filtration, the Permittee again adds chlorine, caustic, and corrosion inhibitor. Treated
water is stored in a 500K-gallon wet well. The Permittee backwashes the filters with finished drinking water
treated with additives.
Product flows to the clarifier where solids settle out and the supernate flows by gravity to the discharge
outfall. Sludge is pumped from the clarifier by pump truck and hauled to a settling lagoon at the Town's
WWTP.
CORRESPONDENCE - ELGIBILITY FOR GENERAL PERMIT NCG590000
Based on its discharge record, Ramseur WTP qualifies technically for General Permit NCG59
[passed 83% of WET tests; passed last four (4)]. However, the Permittee has not responded to
written or oral correspondence regarding their potential request to rescind the previous and reapply.
NPDES emailed Mayor Danny Shaw on 20Jan enclosing an explanatory letter and a copy of
NCG59 [cc Mark Gross (ORC), Julie Grzyb (NPDES) Sherri Knight (W-SRO)]. By 10Feb, the
Permittee had not responded, so NPDES called Mayor Shaw directly to discuss. He had not read the
letter, so NPDES emailed him second copies [letter and General permit]. He said he'd have to
consult the Town Council.
Considering no comment from the Permittee to date (76 days), NPDES will not rescind, but
proceed with renewal of the existing permit in accord with current WTP strategies for conventional
treatment.
Fact Sheet — Renewal May2016
NPDES NC0074454
Page 1 of 2
COMPLINACE HISTORY
The facility's compliance history is excellent; no NOVs. BIMS shows two TRC limit exceedences
but at levels below the state compliance [50 µg/L]. The record also lists two monitoring -frequency
violations in 2016 for flow and TRC, no action BPJ.
PERMITTING STRATEGY
The Permittee discharges at an instream waste concentration (IWC) of 5.7%. Chronic testing is
required of all WTP discharges with IWC > 0.25%. Although the permit previously required
Chronic WET -test TGA3B, renewal will update this test method to test -method TGP3B @ 90%
[See section A. (2.)], in accord with the Water Treatment Plant Guidance (2009) for conventional
WTP facilities (as amended in 2012).
SUMMARY OF PROPOSED CHANGES
The following will be incorporated for this renewal (per current WTP Strategy):
• discontinued monitoring for Total Iron and Total Manganese
• added permit limits for Total Aluminum (RP = Yes)
• added monitoring for Total Fluoride
• updated Chronic WET test from TGA3B to TGP3B, per WTP Guidance (2012).
• updated Supplement to Cover Sheet
• updated facility map
• added monitoring for Total Hardness [effluent and upstream] to establish a
database to evaluate the soluble metals required by EPA [see section A. (5.)].
PROPOSED SCHEDULE FOR PERMIT ISSUANCE

Review of Renewal Application — AD -INFO Request
NPDES Permit NC0074454 (Class 1)
for Ramseur Water Treatment Plant (WTP)
797 NC Hwy 22 North, Ramseur
Randolph County
Division of Water Resources (DWR or the Division) has received and reviewed your request to renew the
subject NPDES permit for Ramseur's potable Water Treatment Plant (WTP). We are pleased to inform
you that your facility now qualifies for WTP General Permit NCG590000.
You may prefer this General Permit because the monitoring requirements are generally less stringent than
the individual NPDES permit; they are tailored specifically to WTP parameters of concern. In addition,
renewal fees are $100/yr instead of $850/yr, and the renewal process is much simpler. While we renew
General Permit NCG590000 every five years (including the required Public Notice), you may renew your
Certificate of Coverage (COC) under this permit simply by completing a short renewal form. DWR will
transmit your renewed COC and a copy of the updated NCG590000 at the same time.
Please review the attached General Permit NCG590000 with regard to treatment processes, and decide if
you wish to take advantage of this new permit. Note that Ramseur WTP utilizes conventional treatment
technology [coagulation, flocculation, sedimentation, filtration] discharging to surface freshwater.
Therefore, your facility would be subject requirements in the attached document listed on page 5 [B. (3.)]
for Conventional WTP Effluent Limitations and Monitoring Requirements — Discharging to
Freshwater.
To switch to the General permit, the Town of Ramseur must submit a written request to DWR. Please
note that coverage under the General Permit requires DWR to rescind the subject permit. To request the
Division to proceed please respond with something like the following:
The Town of Ramseur has reviewed the Division of Water Resources' General Permit
NCG590000 for conventional -type water treatment plants, and requests that Ramseur WTP's
discharge be covered under this new general permit. The Town understands that the Division
will rescind individual NPDES permit NC0074454 for Ramseur's WTP and replace it with a
Certificate of Coverage (COC) under General Permit NCG590000.
Your written request to DWR must be signed by a legally authorized official of Town of Ramseur in
accordance with 15A NCAC 02H .0106(e).
Nothing Compares.

Mark — Good talking to yolk. I've been assigned to review your renewal application for the subject permit.
As discussed, we need five (5) samples each for Hardness [Ca + Mg or CaCO3]; sample both upstream and effluent (10
samples total), as may be convenient to your regular discharge. We'II use these data to supplement our review of your
permit renewal. Electronic copies of lab reports are preferred and appreciated.
Thanks in advance for your help. Any questions, email me or call my direct line (919-807-6394).

6. Description of source water(s) (i.e. groundwater, surface water)
Surface Water (Sandy Creek)
7. Describe the treatment process(es) for the raw water:
The raw water is withdrawn from Sandy Creek into the flash mixer where the ferric, sodium
hydroxide is added. On an as needed basis, carbon and polymer are introduced at the
flocculator prior to the sedimentation basin. Prior to filtration the water is chlorinated. After
filtration, chlorine, caustic, and a corrosion inhibitor is added to the water. The treated water is
stored in a 0.5 MG clearwell.
8. Describe the wastewater and the treatment process(es) for wastewater generated by the
facility:
Water goes to the clarifier where solids settle out and the supernate gravity flows to the discharge
point to the receiving stream. Sludge is pumped from clarifier by pump trucks and hauled to
lagoon at waste treatment plant.
9. Number of separate discharge points: 1
Outfall Identification number(s) 001
