NEGATES ANY OTHER REPRESENTATION OR WARRANTY, WRITTEN OR ORAL, EXPRESS OR IMPLIED, INCLUDING,
BUT NOT LIMITED TO, ANY REPRESENTATION OR WARRANTY WITH RESPECT TO MERCHANTABILITY OR FITNESS
FOR ANY PARTICULAR PURPOSE AS RELATED TO THE CREDITS.
Event of Default. For purposes of this Agreement, a party shall be in default(each of the following, an "Event of
Default"): (i) if that party fails to make, when due, any payment required pursuant to this Agreement if such
failure is not remedied within five (5) business days of written notice from the other party; (ii) if that party
materially breaches any or all of its obligations under this Agreement and such breach is not cured within ten(10)
business days of written notice of such breach from the other party; (iii) if any representation or warranty made

Remedies upon Default. If an Event of Default occurs on the part of either party and is continuing, the non-
defaulting party may,at its sole option, upon five(5)business days'written notice and opportunity to cure to the
defaulting party,terminate this Agreement.
Failure to Deliver/Receive. Notwithstanding anything in this Agreement to the contrary,the remedies set forth in
this section are the exclusive monetary remedies of the performing party for the other party's failure to (i)take
delivery of all or any portion of the Credits specified hereunder, or (ii) deliver all or any portion of the Credits
specified herein,as applicable.
If Buyer fails to take delivery of all or any portion of the Quantity of Credits specified herein and such failure is
not excused under the terms of this Agreement (including, without limitation, due to a Change in Law [defined
below]),Buyer shall pay Seller,within five(5)business days of invoice receipt,an amount equal to the sum of the
Unit Price multiplied by the quantity for any Credits delivered to Buyer for which Seller has not been paid;plus(i)
reasonable actual,documented legal fees and costs incurred by Seller in enforcement and protection of its rights
under this Agreement;plus(ii)interest as described herein.
If Seller fails to deliver all or any portion of the Quantity of Credits to Buyer specified herein and such failure is
not excused under the terms of this Agreement, then Seller shall pay Buyer, within five (5) business days of
invoice receipt, an amount equal to $1000, plus reasonable actual, documented legal fees and costs incurred by
Buyer in enforcement and protection of its rights under this Agreement. In addition to monetary damages as
allowed by this Section, Buyer may sue for specific performance of this Agreement. The parties agree that an
PPAB 5519R21v2

order of the court enforcing the consummation of the sale and delivery of the Credits is an appropriate remedy in
the event of a Seller Default.
Change of Law. Should any change in law governing the Credits occur prior to Buyer's receipt of transfer
documents evidencing that the Credits have been transferred to Buyer,and such change of law restricts or limits
the transferability of the Credits (i.e. not simply a clarification or modification of existing law which has little or
no effect on the ability of the parties hereto to effectuate this sale transaction or upon the nature and quality of
the Credits) (a "Change of Law"), then Buyer's sole recourse and remedy shall be to terminate this Agreement
upon written notice to Seller, and upon Buyer's exercising of said termination, Seller shall return any amounts
received from Buyer (if applicable) and Buyer shall cooperate to effect the return of the Credits to Seller (if
applicable), and thereafter no party shall have any further liability or obligation to any other party hereto. If a
Change of Law occurs after Buyer's receipt of documentation evidencing that the Credits have been transferred
to Buyer or Buyer's designee,then Buyer shall have no recourse or remedy against Seller.
Limitations of Liability. THE EXPRESS REMEDIES AND MEASURES OF DAMAGES PROVIDED HEREIN SATISFY THE
ESSENTIAL PURPOSES HEREOF. FOR BREACH OR DEFAULT ARISING FROM ANY PROVISION FOR WHICH AN
EXPRESS REMEDY IS PROVIDED HEREIN, SUCH REMEDY OR MEASURE OF DAMAGES SHALL BE THE SOLE AND
EXCLUSIVE REMEDY AND ALL OTHER REMEDIES OR DAMAGES AT LAW OR IN EQUITY ARE WAIVED, INCLUDING
ANY INDEMNIFICATION OBLIGATIONS RELATING THERETO. IF NO REMEDY OR MEASURE OF DAMAGES IS
EXPRESSLY PROVIDED HEREIN, LIABILITY SHALL BE LIMITED TO DIRECT, ACTUAL DAMAGES ONLY. SUCH DIRECT,
ACTUAL DAMAGES SHALL BE THE SOLE AND EXCLUSIVE REMEDY, AND ALL OTHER REMEDIES OR DAMAGES AT
LAW OR IN EQUITY ARE WAIVED. EXCEPT AS MAY BE INCLUDED IN AN EXPRESS REMEDY PROVIDED FOR HEREIN,
NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY FOR ANY INDIRECT, SPECIAL, CONSEQUENTIAL, PUNITIVE
OR EXEMPLARY DAMAGES ARISING OUT OF OR RELATED TO THIS AGREEMENT, INCLUDING LOST PROFITS
(EXCEPT TO THE EXTENT THAT THE PAYMENTS REQUIRED TO BE MADE PURSUANT TO THIS AGREEMENT ARE
DEEMED TO BE SUCH DAMAGES) OR BUSINESS INTERRUPTION DAMAGES, WHETHER BASED ON STATUTE,
CONTRACT, TORT, UNDER ANY INDEMNITY OR OTHERWISE, WITHOUT REGARD TO CAUSE OR THE NEGLIGENCE
OF ANY PARTY, WHETHER SOLE, JOINT, ACTIVE OR PASSIVE, AND EACH PARTY HEREBY RELEASES THE OTHER
PARTY FROM ANY SUCH LIABILITY, EVEN IF DURING THE TERM HEREOF IT ADVISES THE OTHER OF THE
POSSIBILITY OF SUCH DAMAGES. TO THE EXTENT ANY DAMAGES REQUIRED TO BE PAID HEREUNDER ARE
LIQUIDATED,THE PARTIES ACKNOWLEDGE THAT THE DAMAGES ARE DIFFICULT OR IMPOSSIBLE TO DETERMINE,
OR OTHERWISE OBTAINING AN ADEQUATE REMEDY IS INCONVENIENT AND THE DAMAGES CALCULATED
HEREUNDER CONSTITUTE A REASONABLE APPROXIMATION OF THE HARM OR LOSS AND ARE NOT A PENALTY.
Confidentiality. To the extent allowable by law, the parties agree to keep confidential the contents of this
Agreement and any information made available by one party to the other party with respect to this Agreement
(the"Confidential Information")except:(i) in respect of information that is or becomes generally available to the
public other than as a result of a disclosure by either party in violation of this Agreement; (ii) in respect of
information that was already known by either party on a non-confidential basis prior to the execution of this
Agreement;(iii)in respect of information that becomes available to either party on a non-confidential basis from
a source other than the other party where such source is not known by the receiving party to be subject to a
confidentiality obligation with respect to such information; (iv) to the extent required by any administrator or
regulatory agency in order to effectuate the transaction contemplated by this Agreement or to comply with
applicable law; (v) in respect of information that is independently derived and is not directly attributable to the
party with respect to which it relates;and(vi)to the professional advisors of each party, provided that each party
ensures that the matters disclosed are kept confidential. The parties acknowledge and agree that in the event of
a breach of this confidentiality provision monetary damages may be insufficient to make the non-disclosing party
whole; as such, the non-disclosing party shall be entitled to seek equitable relief, including injunctive relief and
specific performance,in addition to all other remedies available at law or in equity.Seller agrees that publication
of this Agreement, in its totality, as part of Town Council meeting agendas or in response to a public records
request pursuant to N.C.G.S.§132 is not a breach of this Agreement.
Notices. All notices,demands,and other communications hereunder shall be effective only if given in writing and
shall be deemed given (i) when delivered in person; (ii) when delivered by a reputable overnight carrier (with
confirmation of delivery);(iii)when transmitted by facsimile or e-mail (with confirmation of transmission); or(iv)

hereunder to the extent such obligations are assumed by the assignee.
Amendment. This Agreement may be amended at any time, but only by a written agreement signed by both
parties.
No Waiver. No delay or omission by a party in the exercise of any right under this Agreement shall be taken,
construed, or considered as a waiver or relinquishment thereof. If any of the terms and conditions herein are
breached and thereafter waived in writing by a party, such waiver is limited to the particular breach so waived
and is not deemed to waive any other breach hereunder.
Severability. If any provision or portion of this Agreement is found to be unenforceable,the remainder shall be
enforced as fully as possible and the unenforceable provision shall be deemed modified to the limited extent
required to permit its enforcement in a manner most closely representing the intention of the Parties as
expressed herein.
Complete Agreement. This Agreement represents the parties' final and mutual understanding concerning its
subject matter. It replaces and supersedes any prior agreements or understandings,whether written or oral.
Governing Law. This Agreement shall be construed in accordance with and governed by the laws of the State of
North Carolina, excluding any choice of law or conflicts of law rules or principles that would result in application
of the laws of a different jurisdiction.

referred to representatives of the parties for informal dispute resolution discussions as soon as practicable. In
the event that the designated representatives do not reach a mutually acceptable resolution of the dispute

laying of venue of any such proceedings brought in any such court,waives any claim that such proceedings have
been brought in an inconvenient forum and further waives the right to object,with respect to such proceedings,
that such court does not have any jurisdiction over such party. Nothing in this Agreement to the contrary shall,
or is intended to, prevent either party from bringing an action in equity to seek injunctive relief, if necessary, to
avoid irreparable harm. EACH PARTY WAIVES ITS RESPECTIVE RIGHT TO ANY JURY TRIAL WITH RESPECT TO ANY
LITIGATION ARISING UNDER OR IN CONNECTION WITH THIS AGREEMENT.
Counterparts. This Agreement may be executed in counterparts,each of which shall be deemed an original, and
all of which together shall be deemed to be one and the same instrument. Scanned and e-mailed copies of the
signed Agreement or other electronic transmission of any signed original document, will be the same as delivery
of any original document.
Further Assurances. Each party shall provide the other party any reasonably requested information or
documentation required to effect a transfer of Credits pursuant to the terms of this Agreement,will cooperate to

Subject: Issuance of NPDES Permit Modification
Permit NC0025453
Sam's Branch WRF
Johnston County
Grade IV Biological WPCS
SIC Code 4952
Dear Mr.Warren:
In accordance with Town of Clayton's request to include newly purchased nutrient offset
credits in its NPDES permit, and having received documentation of that purchase,the Division
of Water Resources is forwarding herewith the revised permit for the Sam's Branch Water
Reclamation Facility.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 published notice of the draft permit on July 23,2020,in The News and Observer
inviting public comment on the proposed modification.We received no response from the
general public.The Division's Public Water Supply Section provided its concurrence the permit,
as is necessary for discharges to Water Supply waters. And Restoration Systems/ FR Flat
Swamp and our Nutrient Offset and Riparian Buffer Mitigation Banking Program suggested
certain changes and clarification.
RS Flat Swamp, LLC has,by its September 4,2020 Nutrient Offset Credit Transfer Certificate,
documented that the Town has purchased and paid in full for 715,858.18 lbs (23,861.94 lbs/yr
for 30 years) of Nitrogen Offset Credits available from the RS Flat Swamp Mitigation Bank.The
Division accepts this as sufficient for the issuance of the subject permit modification.
The Division is issuing the permit modification as originally proposed except for two minor
changes:

Issuance of NPDES Permit Modification
Permit NC0025453
September 15,2020
• The September 4 purchase date for the offset credits has been added to the table of
allocations and offset credits in Condition A.(6.) of the permit;and
• Footnote 3 below that same table has been split into two footnotes.Footnote 3 still
describes the offset credits purchase but,consistent with our Mitigation Banking
Program,no longer refers to"estuary" credits.The new Footnote 4 describes the
application of the credits in the Town's permit,including transport considerations and
application of the uncertainty ratio from the Neuse rule,15A NCAC 02B.0713 (formerly
.0234).The allocations and credits listed in the table have not been changed.
Although the Transfer Certificate and the permit describe the credits as having a 30-year term,it
is our intent to convert them to permanent credits as allowed in the revised Neuse wastewater
rule,15A NCAC 02B .0713 (formerly 02B .0234).We will work with you to effect that change.
If any parts,measurement frequencies or sampling requirements contained in this permit are
unacceptable to you,you have the right to an adjudicatory hearing upon written request within
thirty(30) days following receipt of this letter. This request must be in 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 require modification or revocation and reissuance of the permit. This permit does not
affect the legal requirements to obtain any other Federal,State,or Local governmental permit
that may be required. If you have any questions concerning the permit,please contact Mike
Templeton at(919) 707-3603 or at [e-mail].

Sample locations I-Influent,E-Effluent,U-Upstream=at NCSR 1700,D-Downstream= (1)NC HWY 42 and
(2) NCSR 1908. Upstream and downstream samples shall be grab samples collected 3/week during
June,July,August,and September and 1/week during the remainder of the year.Instream sampling
requirements are provisionally waived in light of the permittee's participation in the Lower Neuse River
Basin Association.Should participation in the association cease,all instream sampling requirements are
immediately reinstated.
The monthly average effluent BOD5 and Total Suspended Solids concentrations shall not exceed 15% of the
respective influent value(85% removal).
The Division shall consider all effluent total residual chlorine values reported below 50 µg/1 to be in
compliance with the permit. However,the permittee shall continue to record and submit all values
reported by a North Carolina certified laboratory (including field certified),even if these values fall
below 50 µg/l.
For a given wastewater sample,TN =TKN +NO3-N+NO2-N,where TN is Total Nitrogen,TKN is Total
Kjeldahl Nitrogen,and NO3-N and NO2-N are Nitrate and Nitrite Nitrogen,respectively.
Chronic Toxicity (Ceriodaphnia dubia) P/F at 2% with testing in March,June,September,and December.
See Special Condition A. (2.).
The permittee shall perform three effluent pollution scans during the term of this permit.See Special
Condition A. (3.).
Twice per week sampling must occur on any two non-consecutive days during the calendar week.
TN Load is the mass load of TN discharged by the permittee in a period of time.See Special Condition A.
(4.).
Compliance with these limits shall be determined in accordance with Special Condition A. (5.),Annual
Limits for Total Nitrogen.
The permittee shall sample instream hardness upstream of the facility's discharge.The sample shall be
representative of the hardness in the stream. If the permittee is a member of the Monitoring Coalition
Program,sampling for instream hardness may be waived as long as the Monitoring Coalition agrees to
sample hardness at the nearest upstream location,at a minimum frequency of quarterly,and the
permittee has obtained approval from DWR-NPDES Permitting Unit that the upstream station being
monitored by the coalition is representative of the receiving stream for this discharge.The permittee is
responsible for submitting instream hardness test results with its DMRs as results are received from the
coalition.If coalition membership is cancelled or the Monitoring Coalition terminates instream hardness
sampling at the approved station,the permittee will immediately notify the Division and resume
sampling for instream hardness,upstream of its discharge,as required in Section A. (1.). Effluent
hardness shall be performed in conjunction with testing for hardness dependent metals (cadmium,
copper,lead,nickel,silver,and zinc).
(b.) There shall be no discharge of floating solids or visible foam in other than trace amounts.
A.(2.) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY) [15A NCAC 02B.0200]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 2%.
The permit holder shall perform at a minimum,quarterly monitoring using test procedures outlined in
the"North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010,or
subsequent versions or"North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised-December 2010) or subsequent versions. The tests will be performed during the months of
March,June, September,and December. These months signify the first month of each three-month
toxicity testing quarter assigned to the facility. Effluent sampling for this testing must be obtained
4 of 12

Permit NC0025453
during representative effluent discharge and shall be performed at the NPDES permitted final effluent
discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV
'n shall beperformed at a
minimum,
in
below the permit limit,then multiple-concentration testing s a
each of the two following months as described in"North Carolina Phase II Chronic Whole Effluent
Toxicity Test Procedure" (Revised-December 2010) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered electronically using
the Division's eDMR system for the month in which tests were performed,using the parameter code
TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally, DWR Form AT-3
(original) is to be sent to the following address:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh,NC 27699-1621
Or,results can be sent to the email, [e-mail].
Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Section no later than 30
p
days after the end of the reporting period for which the report is made.
g
Test data shall be complete,accurate, include all supporting chemical/physical measurements and all
concentration/response data,and be certified by laboratory supervisor and ORC or approved
designate signature. Total residual chlorine of the effluent toxicity sample must be measured and
reported if chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is
required,the permittee will complete the information located at the top of the aquatic toxicity (AT) test
form indicating the facility name,permit number,pipe number,county,and the month/year of the
report with the notation of"No Flow" in the comment area of the form. The report shall be submitted
to the Water Sciences Section at the address cited above
Should the permittee fail to monitor during a month in which toxicity monitoring is required,
monitoring will be required during the following month. Assessment of toxicity compliance is based on
the toxicity testing quarter,which is the three month time interval that begins on the first day of the
month in which toxicity testing is required by this permit and continues until the final day of the third
month.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Water Resources indicate potential impacts to the receiving stream, this permit may be re-
opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document,such as minimum
control organism survival,minimum control organism reproduction,and appropriate environmental
invalid test and will require immediate follow
-up testingto be
controls,shall constitute an q
completed no later than the last day of the month following the month of the initial monitoring.
A.(3.) EFFLUENT POLLUTANT SCAN (Municipal POTWs) [G.S. 143-215.1(b)]
The permittee shall perform a total of three (3) Effluent Pollutant Scans for all parameters listed below.
One scan must be performed in each of the following years: 2021,2022,and 2023. Analytical methods
shall be in accordance with 40 CFR Part 136 and shall be sufficiently sensitive to determine whether
parameters are present in concentrations greater than applicable standards and criteria.Samples

The permittee shall report discharge monitoring data electronically using the NC DWR's Electronic
Discharge Monitoring Report (eDMR) internet application.
9 of 12

Permit NC0025453
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 interne. 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.
Starting on December 21,2020,the permittee must electronically report the following compliance
monitoring data and reports,when applicable:
• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports;and
• Clean Water Act(CWA)Section 316(b)Annual Reports.
The permittee may seek an electronic reporting waiver from the Division(see"How to Request a
Waiver from Electronic Reporting" section below).
2. Electronic Submissions
In accordance with 40 CFR 122.41(1)(9),the permittee must identify the initial recipient at the time
of each electronic submission. The permittee should use the EPA's website resources to identify the
initial recipient for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity
(EPA or the state authorized by EPA to implement the NPDES program)that is the designated
entity for receiving electronic NPDES data[see 40 CFR 127.2(b)].
EPA plans to establish a website that will also link to the appropriate electronic reporting tool for
each type of electronic submission and for each state. Instructions on how to access and use the
appropriate electronic reporting tool will be available as well. Information on EPA's NPDES
Electronic Reporting Rule is found at:
https://www.federalregister.gov/documents/2015/10/22/2015-24954/national-pollutant-
discharge-elimination-system-npdes-electronic-reporting-rule
Electronic submissions must start by the dates listed in the"Reporting Requirements" section
above.

3. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an
electronic reporting waiver,a permittee must first submit an electronic reporting waiver request to
the Division. Requests for temporary electronic reporting waivers must be submitted in writing to
the Division for written approval at least sixty (60) days prior to the date the facility would be
required under this permit to begin submitting monitoring data and reports. The duration of a
temporary waiver shall not exceed 5 years and shall thereupon expire. At such time, monitoring
data and reports shall be submitted electronically to the Division unless the permittee re-applies for
and is granted a new temporary electronic reporting waiver by the Division. Approved electronic
reporting waivers are not transferrable. Only permittees with an approved reporting waiver
request may submit monitoring data and reports on paper to the Division for the period that the
approved reporting waiver request is effective.
Information on eDMR and the application for a temporary electronic reporting waiver are found on
the following web page:
http://deq.nc.gov/about/divisions/water-resources/edmr
