Subject: Issuance of NPDES Permit NC0088889
Hopson Downs Subdivision Well#4 WTP, Class PC-1
Spence Farms Road, Holly Springs
Wake County
Dear Mr. Becker:
The Division of Water Resources (DWR of the Division)has approved your application to renew
the subject permit. Accordingly, we are forwarding the attached NPDES discharge permit. This
permit is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and
the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection
Agency dated October 15, 2007 (or as subsequently amended).
The Division has reviewed your Engineering Alternatives analysis (EAA) for the subject site,
submitted with your application to renew. The EAA presents present-value costs and rationale
for land-based disposal, surface irrigation, reuse, discharge to a POTW [closest connection 5.5
miles away], and a surface-water discharge. DWR concurs that a discharge to surface waters is
the best viable disposal alternative based on cost.
Changes for Renewal.We understand that the subject facility has not discharged since before the
previous permit cycle (2009), i.e., the Basinwide Information Management System (BIMS)has no
discharge records (Jan2005 —May2018). This draft reflects your stated intent to re-equip this
facility with a new treatment array of greensand filters. The NPDES Unit has therefore applied
the current WTP permitting guidance (2009) for use of greensand technology, with consideration
of projected flows of 88 gpm [-0.127 GPD] based on pumping-well capacity submitted with your
application to renew. Please note one change from the permit draft—we have deleted monitoring
for Total Manganese as it is no longer a parameter of concern.
We have continued monitoring for Total Copper, Total Zinc and Total Manganese as parameters
of concern, per current permitting guidance for greensand. We have also added monitoring for
Total Hardness (effluent and upstream) to evaluate metals in dissolved fraction, as required by
EPA (see permit section [A. (1.)]. This permit also includes monitoring for Total Nitrogen(TN)
and Total Phosphorus (TP)required of discharges under the Neuse River Basin Management
Strategy.

Because this facility's preferred operation is 100%recycle, and therefore having no effluent
database(discharging only on rare occasions), and because monitoring for Total Nitrogen a(TN)
and Total Phosphorus (TP) are required of discharges, Hopson Downs Subdivision Well#4 WTP
is not currently eligible for transfer to General Permit NCG590000.
Division records show that you have successfully registered with the eDMR Program. Please be
reminded that until the state's eDMR application is approved compliant with EPA's Cross-
Media Electronic Reporting Regulation (CROMERR), all permittees must continue to submit
hardcopy of DMRs as backup to eDMR reporting [see permit section A. (4.)].
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 following receipt of this letter. This request must take the form of a written petition,
conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of
Administrative Hearings (6714 Mail Service Center, Raleigh,North Carolina 27699-6714).
Unless such demand is made,this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division
may modify or revoke and reissue this permit. This permit does not affect your legal
requirements to obtain other permits required by the Division of Water Resources, the Division
of Land Resources, the Coastal Area Management Act or any other federal or local government.
If you have any questions concerning this permit, please contact Joe Corporon

is not currently eligible for transfer to General Permit NCG590000.
Division records show that you have successfully registered with the eDMR Program. Please be
reminded that until the state's eDMR application is approved compliant with EPA's Cross-
Media Electronic Reporting Regulation (CROMERR), all permittees must continue to submit
hardcopy of DMRs as backup to eDMR reporting [see permit section A. (4.)].
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 following receipt of this letter. This request must take the form of a written petition,
conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of
Administrative Hearings (6714 Mail Service Center, Raleigh,North Carolina 27699-6714).
Unless such demand is made, this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division
may modify or revoke and reissue this permit. This permit does not affect your legal
requirements to obtain other permits required by the Division of Water Resources, the Division

A. (2.) ELECTRONIC REPORTING - DISCHARGE MONITORING REPORTS
[G.S. 143-215.1(b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program
reports. The final NPDES Electronic Reporting Rule was adopted and became effective on December
21, 2015.
NOTE: This special condition supplements or supersedes the following sections within Part II of this
permit(Standard Conditions for NPDES Permits):
• Section B. (11.) Signatory Requirements
• Section D. (2.) Reporting
• Section D. (6.) Records Retention .
• • Section E. (5.) Monitoring Reports
1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)]
The permittee shall report discharge monitoring data electronically using the NC DWR's Electronic
Discharge Monitoring Report(eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. Until such time that the state's
eDMR application is compliant with EPA's Cross-Media Electronic Reporting Regulation
(CROMERR), permittees will be required to submit all discharge monitoring data to the state
electronically using eDMR and will be required to complete the eDMR submission by printing,
signing, and submitting one signed original and a copy of the computer printed eDMR to the
following address:
NC DEQ/Division of Water Resources/Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh,North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility
being physically located in an area where less than 10 percent of the households have broadband
access, then a temporary waiver from the NPDES electronic reporting requirements may be granted
and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1.1, 2, 3) or
alternative forms approved by the Director. Duplicate signed copies shall be submitted to the
mailing address above. See"How to Request a Waiver from Electronic Reporting" section below.
Regardless of the submission method, the first DMR is due on the last day of the month following
the issuance of the permit or in the case of a new facility, on the last day of the month following the
commencement of discharge.

307(b), (c)or(d)of the CWA. [40 CFR 403.3 (i)and(j)and 15A NCAC 02H.0903(b)(11)]
Interference
Inhibition or disruption of the POTW treatment processes; operations;or its sludge process,use,or disposal which
causes or contributes to a violation of any requirement of the Permittee's(or any satellite POTW's if different from the
Permittee)NPDES,collection system,or non-discharge permit or prevents sewage sludge use or disposal in
compliance with specified applicable State and Federal statutes,regulations,or permits. [15A NCAC 02H
.0903(b)(14)]
Pass Through
A discharge which exits the POTW into waters of the State in quantities or concentrations which,alone or with
discharges from other sources,causes a violation,including an increase in the magnitude or duration of a violation,of
the Permittee's(or any satellite POTW's,if different from the Permittee)NPDES, collection system,or non-discharge
permit. [15A NCAC 02H .0903(b)(23)]
Publicly Owned Treatment Works(POTW)
A treatment works as defined by Section 212 of the CWA,which is owned by a State or local government organization.
This definition includes any devices and systems used in the storage,treatment,recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature.It also includes the collection system, as defined in 15A NCAC 2T
.0402,only if it conveys wastewater to a POTW treatment plant. The term also means the local government
organization,or municipality,as defined in section 502(4)of the CWA,which has jurisdiction over indirect discharges
to and the discharges from such a treatment works.In this context,the organization may be the owner of the POTW
treatment plant or the owner of the collection system into which an indirect discharger discharges.This second type of
POTW may be referred to as a"satellite POTW organization." [15A NCAC 02H .0903(b)(26)]
"Significant Industrial User" or"SIU"
An Industrial User that discharges wastewater into a publicly owned treatment works and that [15A NCAC 02H
.0903(b)(33)]:
1. Discharges an average of 25,000 gallons per day or more of process wastewater to the POTW(excluding sanitary,
noncontact cooling and boiler blowdown wastewaters);or
2. Contributes process wastewater which makes up five percent or more of the NPDES or non-discharge permitted
flow limit or organic capacity of the POTW treatment plant. In this context,organic capacity refers to BOD,TSS
and ammonia; or
3. Is subject to categorical standards under 40 CFR Part 403.6 and 40 CFR Parts 405-471; or
4. Is designated as such by the Permittee on the basis that the Industrial User has a reasonable potential for adversely
affecting the POTW's operation or for violating any pretreatment standard or requirement, or the POTW's effluent
limitations and conditions in its NPDES or non-discharge permit,or to limit the POTW's sludge disposal options;
5. Subject to approval under 15A NCAC 02H.0907(b),the Permittee may determine that an Industrial User meeting
the criteria in paragraphs 1 or 2 of this definition above has no reasonable potential for adversely affecting the
POTW's operation or for violating any pretreatment standard or requirement,the POTW's effluent limitations and
conditions in its NPDES or non-discharge permit, or to limit the POTW's sludge disposal options,and thus is not a
Significant Industrial User(SIU); or
6. Subject to approval under 15A NCAC 02H.0907(b),the Permittee may determine that an Industrial User meeting
the criteria in paragraph 3 of this definition above meets the requirements of 40 CFR Part 403.3(v)(2)and thus is a
non-significant categorical Industrial User.
