Subject: Pretreatment Review of Enforcement Response Plan (ERP)
Stanly County
Stanly County,NPDES#: NC0043532
Dear Mr. Wingo: •
The Municipal Unit of the Division of Water Resources has reviewed the Enforcement Response Plan
(ERP),titled: Stanly County Industrial Pretreatment Enforcement Response Guide.This submission was
received by the Division on February 8, 2023.
The review indicates that the ERP is adequate and meets the requirements of 15A NCAC 02H .0905
(b)(7) and 40 CFR 403.8 (f)(5). Proper implementation of an ERP is required by the Town's NPDES
permit and you must follow this approved ERP for all enforcement actions. Modifications to this ERP
must be approved by the Division.
1 Within 180 days of the effective date of any reissued/modified wastewater treatment facility permit,the
Permittee would be required to submit to the Division a written technical evaluation ofthe need n h to revise
local limits(i.e., an updated IWS,or documentation of why one is not needed).This action may include
revising,updating,or adding to the list of SIUs.Pursuant to 15A NCAC 02H.0907(b)either the Division
or the permittee may initiate pretreatment program revisions.
Thank you for your continued support of the Pretreatment Program. If you have any questions or
comments, please contact Keyes McGee at [phone] [email: [e-mail]].

5.9 Notification of the Discharge of Hazardous Waste
The County prohibits the discharge of any hazardous wastes without notification to and approval by the POTW
Director.
Stanly County Sewer Use Ordinance Page 22 of 32 July 1,2022

(a) Any user who commences the discharge of hazardous waste shall notify the POTW, the EPA
Regional Waste Management Division Director,and State hazardous waste authorities,in writing,
of any discharge into the POTW of a substance which, if otherwise disposed of, would be a
hazardous waste under 40 CFR Part 261. Such notification must include the name of the
hazardous waste as set forth in 40 CFR Part 261,the EPA hazardous waste number, and the type
of discharge (continuous, batch, or other). If the user discharges more than one hundred (100)
kilograms of such waste per calendar month to the POTW, the notification also shall contain the
following information to the extent such information is known and readily available to the user:
an identification of the hazardous constituents contained in the wastes, an estimation of the mass
and concentration of such constituents in the waste stream discharge during the calendar month,
and an estimation of the mass and concentration of such constituents in the waste stream expected
to be discharged during the following twelve (12) months. All notifications must take place no
later than one hundred eighty (180) days before the discharge commences. The user shall not
begin the discharge until receiving written approval from the County. Any notification under this
paragraph need be submitted only once for each hazardous waste discharge. However,
notifications of changed conditions must be submitted under section 5.5 of this ordinance. The
notification requirement in this section does not apply to pollutants already reported by users
subject to categorical pretreatment standards under the self-monitoring requirements of sections
5.1,5.3,and 5.4 of this ordinance.
(b) Dischargers are exempt from the requirements of paragraph(a),above,during a calendar month in
which they discharge no more than fifteen(15)kilograms of hazardous wastes,unless the wastes
are acute hazardous wastes as specific in 40 CFR 261.30(d) and 261.33(e). Discharge of more
than fifteen(15)kilograms of nonacute hazardous wastes in a calendar month,or of any quantity
of acute hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e), requires a one-time
notification. Subsequent months during which the user discharges more than such quantities of
any hazardous waste do not require additional notification.
(c) In the case of any new regulation under section 3001 of RCRA identifying additional
characteristics of hazardous waste or listing any additional substance as a hazardous waste, the
user must notify the POTW Director, the EPA Regional Waste Management Waste Division
Director, and State hazardous waste authorities of the discharge of such substance within ninety
(90)days of the effective date of such regulations.
(d) In the case of any notification made under this section,the user shall certify that it has a program,
which shall be subject to the POTW Director's review and approval,in place to reduce the volume
and toxicity of hazardous wastes generated to the degree required by the POTW Director and any
applicable local,State,or Federal law or regulation.
(e) This provision does not create a right to discharge any substance not otherwise permitted to be
discharged by this ordinance,a permit issued thereunder,or any applicable Federal or State law.
5.10 Analytical Requirements
All pollutant analyses, including sampling techniques, to be submitted as part of a wastewater discharge permit
application or report shall be performed by a laboratory certified by the State to perform the wastewater analyses in
accordance with the techniques prescribed in 40 CFR Part 136, unless otherwise specified in an applicable
categorical pretreatment standard or unless otherwise performed in accordance with procedures approved by EPA or
County. If 40 CFR Part 136 does not contain sampling or analytical techniques for the pollutant in question,
sampling and analyses must be performed in accordance with procedures approved by EPA and County. Analyses
must be performed by a State certified lab for each parameter analyzed, if such certification exists for that
parameter.
5.11 Grab and Composite Sample Collection
(a) All wastewater samples must be representative of the user's discharge. Wastewater monitoring
and flow measurement facilities shall be properly operated, kept clean, and maintained in good
working order at all times. The failure of a user to keep its monitoring facility in good working
order shall not be grounds for the user to claim that sample results are unrepresentative of its
discharge.
(b) Grab Samples must be used for pH,cyanide,total phenols,oil and grease,sulfide,volatile organic
compounds,and any other pollutants as required by 40 CFR 136. The POTW shall determine the
number of grabs necessary to be representative of the User's discharge. See 40 CFR 403.12(g)(5)
Stanly County Sewer Use Ordinance Page 23 of 32 July 1,2022

for additional grab sample number requirements for BMR and 90 Day Compliance Reports.
Additionally,the POTW Director may allow collection of multiple grabs during a 24 hour period
which are composited prior to analysis as allowed under 40 CFR 136.
(c) Composite Samples: All wastewater composite samples shall be collected with a minimum of
hourly aliquots or grabs for each hour that there is a discharge. All wastewater composite samples
shall be collected using flow proportional composite collection techniques, unless time-
proportional composite sampling or grab sampling is authorized by the POTW Director. When
authorizing time-proportional composites or grabs, the samples must be representative and the
decision to allow the alternative sampling must be documented.
5.12 Timing
Written reports will be deemed to have been submitted on the date postmarked. For reports which are not mailed,
postage prepaid, into a mail facility serviced by the United States Postal Service, the date of receipt of the report
shall govern.
5.13 Record Keeping
Users subject to the reporting requirements of this ordinance shall retain, and make available for inspection and
copying,all records of information obtained pursuant to any monitoring activities required by this ordinance and any
additional records of information obtained pursuant to monitoring activities undertaken by the user independent of
such requirements. Records shall include the date, exact place,method,and time of sampling, and the name of the
person(s) taking the samples; the dates analyses were performed; who performed the analyses; the analytical
techniques or methods used;and the results of such analyses. These records shall remain available for a period of at
least three(3)years. This period shall be automatically extended for the duration of any litigation concerning the
user or the County, or where the user has been specifically notified of a longer retention period by the POTW
Director.
5.14 Electronic Reporting
The POTW Director may develop procedures for receipt of electronic reports for any reporting requirements of this
ordinance. Such procedures shall comply with 40 CFR Part 3. These procedures shall be enforceable under Section
8 of this ordinance.
Stanly County Sewer Use Ordinance Page 24 of 32 July 1,2022

SECTION 6-COMPLIANCE MONITORING
6.1 Monitoring Facilities
The County requires the user to provide and operate at the user's own expense, monitoring facilities to allow
inspection,sampling,and flow measurement of the building sewer and/or internal drainage systems.The monitoring
facility should normally be situated on the user's premises, but the County may, when such a location would be
impractical or cause undue hardship on the user, allow the facility to be constructed in the public street or sidewalk
area and located so that it will not be obstructed by landscaping or parked vehicles.
There shall be ample room in or near such sampling manhole or facility to allow accurate sampling and preparation
of samples for analysis. The facility, sampling,and measuring equipment shall be maintained at all times in a safe
and proper operating condition at the expense of the user.
Whether constructed on public or private property, the sampling and monitoring facilities shall be provided in
accordance with the requirements of the County and all applicable local construction standards and specifications.
Construction shall be completed within ninety(90)days following written notification of approval of construction of
sampling and monitoring facilities by the County.
6.2 Inspection and Sampling
The County will inspect the facilities of any user to ascertain whether the purpose of this ordinance is being met and
all requirements are being complied with. Persons or occupants of premises where wastewater is created or
discharged shall allow the County, Approval Authority and EPA or their representative ready access at all
reasonable times to all parts of the premises for the purposes of inspection, sampling, records examination and
copying or in the performance of any of their duties. The County,Approval Authority and EPA shall have the right
to set up on the user's property such devices as are necessary to conduct sampling, inspection, compliance
monitoring and/or metering operations. Where a user has security measures in force which would require proper
identification and clearance before entry into their premises,the user shall make necessary arrangements with their
security guards so that upon presentation of suitable identification, personnel from the County,Approval Authority
and EPA will be permitted to enter, without delay, for the purposes of performing their specific responsibilities.
Denial of the County's Approval Authority's, or EPA's access to the user's premises shall be a violation of this
ordinance. Unreasonable delays may constitute denial of access.
6.3 Search Warrants
If the County,Approval Authority,or EPA has been refused access to a building,structure,or property,or any part
thereof,and is able to demonstrate probable cause to believe that there may be a violation of this ordinance,or that
there is a need to inspect and/or sample as part of a routine inspection and sampling program of the County designed
to verify compliance with this ordinance or any permit or order issued hereunder, or to protect the overall public
health, safety and welfare of the community,then the County Approval Authority,or EPA may seek issuance of a
search warrant from the court having jurisdiction within the County.
Stanly County Sewer Use Ordinance Page 25 of 32 July 1,2022

SECTION 7- CONFIDENTIAL INFORMATION
(a) Information and data provided by an industrial user to the POTW Director pursuant to this ordinance identifying
the nature and frequency of a discharge, shall be available to the public without restriction. All other information
which may be so submitted by an industrial user to the POTW Director in connection with any required reports shall
also be available to the public unless the industrial user or other interested person specifically identifies the
information as confidential upon submission and is able to demonstrate to the satisfaction of the POTW Director that
the disclosure of such information or a particular part thereof to the general public would divulge methods or
processes entitled to protection as trade secrets pursuant to N.C.G.S.Chapter 132—Public Records.
(b) Information provided by an industrial user to the POTW Director that is determined to be entitled to confidential
treatment shall be made available upon written request to the Division of Water Resources or any State agency for
uses related to the Pretreatment Program, the National Pollutant Discharge Elimination System (NPDES) Permit,
collection system permit,stormwater permit,and/or Non-discharge permit,and for uses related to judicial review or
enforcement proceedings involving the person furnishing the report.
(c) Information and data received by the Division or other State agency under paragraph (b)above shall be subject

ordinance, wastewater permit, or any prohibition, limitation or requirements contained therein or
any other pretreatment requirement the POTW Director may serve upon such a person a written
notice stating the nature of the violation. Within thirty (30)days from the date of this notice, an
explanation for the violation and a plan for the satisfactory correction thereof shall be submitted to
the County by the user. Submission of this plan does not relieve the discharger of liability for any
violations occurring before or after receipt of the notice of violation.
(b) Consent Orders
The POTW Director is hereby empowered to enter into consent orders, assurances of voluntary
compliance,or other similar documents establishing an agreement with the person responsible for
the noncompliance. Such orders will include specific action to be taken by the discharger to
correct the noncompliance within a time period also specified by the order. Consent orders shall
have the same force and effect as an administrative order issued pursuant to section 8.1(d),below.
(c) Show Cause Hearing
The POTW Director may order any industrial user who causes or is responsible for an
unauthorized discharge, has violated this ordinance or is in noncompliance with a wastewater
discharge permit to show cause why a proposed enforcement action should not be taken. In the
event the POTW Director determines that a show cause order should be issued, a notice shall be
served on the user specifying the time and place for the hearing,the proposed enforcement action,
the reasons for such action,and a request that the user show cause why this proposed enforcement
action should not be taken. The notice of the hearing shall be served personally or by registered or
certified mail(return receipt requested)at least ten(10)days before the hearing. Service may be
made on any agent or officer of a corporation.
The POTW Director shall review the evidence presented at the hearing and determine whether the
proposed enforcement action is appropriate.
A show cause hearing under this section is not a prerequisite to the assessment of a civil penalty
under section 8.2 nor is any action or inaction taken by the POTW Director under this section
subject to an administrative appeal under section 10.
(d) Administrative Orders
When the POTW Director finds that an industrial user has violated or continues to violate this
ordinance, permits or orders issued hereunder, or any other pretreatment requirement,the POTW
Director may issue an order to cease and desist all such violations and direct those persons in
noncompliance to do any of the following:
(1) Immediately comply with all requirements;
(2) Comply in accordance with a compliance time schedule set forth in the order;

presents or may present an imminent or substantial endangerment to the health or welfare of
persons or the environment, interferes with the POTW or causes the POTW to violate any
condition of its NPDES or Non-discharge permit.
Any user notified of a suspension of its wastewater treatment service and/or its wastewater permit
shall immediately stop or eliminate the contribution. A hearing will be held within fifteen (15)
Stanly County Sewer Use Ordinance Page 27 of 32 July 1,2022

days of the notice of suspension to determine whether the suspension may be lifted or the user's
waste discharge permit terminated. In the event of a failure to comply voluntarily with the
suspension order, the POTW Director shall take such steps as deemed necessary including
immediate severance of the sewer connection, to prevent or minimize damage to the POTW
system or endangerment to any individuals. The POTW Director shall reinstate the wastewater
permit and the wastewater treatment service upon user's provision of sufficient proof of the
elimination of the noncompliant discharge. Sufficiency of proof shall be determined by the
POTW Director, in his or her sole discretion. The industrial user shall submit a detailed written
statement describing the causes of the harmful contribution and the measures taken to prevent any
future occurrence to the POTW Director prior to the date of the above-described hearing.
(f) Termination of Permit or Permission to Discharge

SECTION 11-AFFIRMATIVE DEFENSES TO DISCHARGE VIOLATIONS
11.1 Upset
(a) An upset shall constitute an affirmative defense to an action brought for noncompliance with
categorical pretreatment standards if the requirements of paragraph(b),below,are met.
(b) A user who wishes to establish the affirmative defense of upset shall demonstrate, through
properly signed,contemporaneous operating logs,or other relevant evidence that:
(1) An upset occurred and the user can identify the cause(s)of the upset;
(2) The facility was at the time being operated in a prudent and workman-like manner and in
compliance with applicable operation and maintenance procedures;and
(3) The user has submitted the following information to the POTW Director within twenty-
four(24) hours of becoming aware of the upset [if this information is provided orally, a
written submission must be provided within five(5)days]:
(A) A description of the indirect discharge and cause of noncompliance;
(B) The period of noncompliance, including exact dates and times or, if not
corrected,the anticipated time the noncompliance is expected to continue;and
(C) Steps being taken and/or planned to reduce,eliminate,and prevent recurrence of
the noncompliance.
(c) In any enforcement proceeding,the user seeking to establish the occurrence of an upset shall have
the burden of proof.
(d) Users will have the opportunity for a judicial determination on any claim of upset only in an
enforcement action brought for noncompliance with categorical pretreatment standards.
(e) Users shall control production of all discharges to the extent necessary to maintain compliance
with categorical pretreatment standards upon reduction, loss, or failure of its treatment facility
until the facility is restored or an alternative method of treatment is provided. This requirement
applies in the situation where, among other things, the primary source of power of the treatment
facility is reduced,lost,or fails.
11.2 Prohibited Discharge Standards Defense
A user shall have an affirmative defense to an enforcement action brought against it for noncompliance with the
general prohibitions in section 2.1 (a)of this ordinance or the specific prohibitions in sections 2.1(b)(2),(3),and(5 -
7)and(9-23)of this ordinance if it can prove that it did not know,or have reason to know,that its discharge,alone
or in conjunction with discharges from other sources,would cause pass through or interference and that either:
(a) A local limit exists for each pollutant discharged and the user was in compliance with each limit
directly prior to,and during,the pass through or interference;or
(b) No local limit exists,but the discharge did not change substantially in nature or constituents from
the user's prior discharge when the County was regularly in compliance with its NPDES permit,
and in the case of interference, was in compliance with applicable sludge use or disposal
requirements.
11.3 Bypass
(a) A user may allow any bypass to occur which does not cause pretreatment standards or
requirements to be violated, but only if it also is for essential maintenance to assure efficient
operation. These bypasses are not subject to the provision of paragraphs (b) and (c) of this
section.
(b)
(1) If a user knows in advance of the need for a bypass,it shall submit prior notice to the
POTW Director,at least ten(10)days before the date of the bypass,if possible.
(2) A user shall submit oral notice to the POTW Director of an unanticipated bypass that
exceeds applicable pretreatment standards within twenty-four(24)hours from the time it
becomes aware of the bypass. A written submission shall also be provided within five(5)
days of this time the user becomes aware of the bypass. The written submission shall
Stanly County Sewer Use Ordinance Page 32 of 32 July 1,2022

contain a description of the bypass and its cause; the duration of the bypass, including
exact dates and times,and, if the bypass has not been corrected,the anticipated time it is
expected to continue; and steps taken or planned to reduce, eliminate, and prevent
reoccurrence of the bypass. The POTW Director may waive the written report on a case-
by-case basis if the oral report has been received within twenty-four(24) hours from the
time it becomes aware of the bypass.
(c)
1 Bypass is prohibited, and the POTW Director maytake an enforcement action against a
O YP g
user for a bypass,unless
(A) In the sole discretion of the POTW Director,bypass was unavoidable to prevent
loss of life,personal injury,or severe property damage;
(B) In the sole discretion of the POTW Director,there were no feasible alternatives
to the bypass, such as the use of auxiliary treatment facilities, retention of
untreated wastes, or maintenance during normal periods of equipment
downtime. This condition is not satisfied if adequate back-up equipment should
have been installed in the exercise of reasonable engineering judgment to
prevent a bypass which occurred during normal periods of equipment downtime
or preventive maintenance;and
(C) The user submitted notices as required under paragraph(b)of this section.
(2) The POTW Director may approve an anticipated bypass, after considering its adverse effects,
if the POTW Director determines that it will meet the three(3)conditions listed in paragraph
(c)(1)of this section.

Subject: Speculative Effluent Limits
West Stanly WWTP
Permit No. NC0043532
Stanly County
Yadkin-Pee Dee River Basin
Dear Mr. Wingo:
This letter provides speculative effluent limits for expansion to 2.5 MGD at the West Stanly
WWTP. The Division received the speculative limits request from the County in a letter dated
November 12, 2019. Please recognize that speculative limits may change based on future water
quality initiatives, and it is highly recommended that the applicant verify the speculative limits
with the Division's NPDES Unit prior to any engineering design work.
Receiving Stream. The Rocky River is located within the Yadkin-Pee Dee River Basin. The
Rocky River has a stream classification of C, and waters with this classification have a best
usage for aquatic life propagation and maintenance of biological integrity,wildlife, secondary
recreation and agriculture. The Rocky River has a summer 7Q10 flow of 29 cubic feet per
second(cfs), a winter 7Q10 flow of 51 cfs, and an annual average flow of 920 cfs.
The Rocky River is currently listed as an impaired waterbody on the 2018 North Carolina
303(d) Impaired Waters List for dissolved copper and turbidity. This impairment may affect
future effluent limits for these parameters.
Based upon a review of information available from the North Carolina Natural Heritage
Program Online Map Viewer, there are not any Federally Listed threatened or endangered
aquatic species identified within a 5-mile radius of the proposed discharge location. If there
are any identified threatened/endangered species, it is recommended that the applicant discuss
the proposed project with the US Fish and Wildlife Service to determine whether the proposed
discharge location might impact such species.
Speculative Effluent Limits. Based on Division review of receiving stream conditions and
water quality modeling results, speculative limits for the proposed expansion to 2.5 MGD are I
presented in Table 1. A complete evaluation of these limits and monitoring requirements for 1

metals and other toxicants, as well as potential instream monitoring requirements, will be
addressed upon receipt of a formal NPDES permit application. Some features of the
speculative limit development include the following:
• BOD/NH3 Limits. These speculative limits are based on freezing current permitted
BOD ultimate loading(i.e.,facility will not be allowed to discharge oxygen-consuming
waste above what is currently permitted). Requests for seasonal limits in accordance
with 15A NCAC 02B .0404 will need to be supported by a QUAL2K or equivalent
water quality model. The resultant limits at expanded flows are considered
technologically-feasible.

expansion.
Engineering Alternatives Analysis(EAA). Please note that the Division cannot guarantee that
an NPDES permit for a new or expanding discharge will be issued with these speculative limits.
Final decisions can only be made after the Division receives and evaluates a formal permit
application for the new/expanded discharge. In accordance with North Carolina
Administrative Code 15A NCAC 2H.0105(c), the most environmentally sound alternative
should be selected from all reasonably cost effective options. Therefore,as a component of all
NPDES permit applications for new or expanding flow, a detailed engineering alternatives
analysis (EAA) must be prepared. The EAA must justify requested flows and provide an
analysis of potential wastewater treatment alternatives. A copy of the Division guidance for
preparing EAA documents is attached.
State Environmental Policy Act (SEPA) EA/EIS Requirements. A SEPA EA/EIS document
may be required for projects that: 1) involve $10 Million or more of state funds; or 2) will
significantly and permanently impact 10 or more acres of public lands. Please check with the
DWR SEPA coordinator (David Wainwright, 919-707-9045) as to whether your project
requires SEPA review. For projects that are subject to SEPA,the EAA requirements discussed
above will need to be folded into the SEPA document. Additionally, if subject to SEPA, the
NPDES Unit will not accept an NPDES permit application for a new/expanding discharge until
Page 2 of 3

the Division has approved the SEPA document and sent a Finding of No Significant Impact
(FONSI) to the State Clearinghouse for review and comment.
Should you have any questions about these speculative limits or NPDES permitting
requirements,please feel free to contact David Hill at(919) 707-3612.

Subject: Re: [External] West Stanly WWTP Speculative Effluent Limits
Doug,
I am not aware of anything that would invalidate these speculative limits such as a new TMDLs. The last TMDL
was approved for the Rocky River in September 2002.
Please note the following:
• These Speculative Limits for the Outfall 002 discharge to the Rocky River with an expansion from 0.9 to
2.5 MGD. They have a backup Outfall 001 that discharges to Long Creek in case of an effluent pump
station failure. The current permit includes an expansion from 0.9 to 1.2 MGD for Outfall 002.
• The Speculative Limits letter indicates important details such as the re-evaluation of toxicant limits
(Copper and Zinc), upon review of a modification application. The current NC 2022 303d list
(4/30/2022) indicates impairment for Turbidity, Copper and Zinc for the Rocky River (Stream Index 13-
17c3).
• The speculative limits were based on freezing current permitted BOD ultimate loading. If they need
seasonal limits, the letter indicates that a QUAL2K model will be needed to support such limits. This in
accordance with 15A NCAC 02B .0404.
• West Stanly WWTP is currently under an SOC for TSS and Fecal Coliform for both Outfalls 001 & 002. I
was involved with review of the SOC application when I was in the Compliance & Expediated
Permitting Unit. Upgrades and expansion is included in the SOC compliance schedule.

STANLY COUNTY
SLUDGE MANAGEMENT PLAN
The West Stanly Wastewater Treatment Plant(WWTP)is a 1.2-MGD extended aeration biological
treatment plant that uses aeration basins and clarifiers as the secondary treatment method.
Residuals generated at the WWTP include waste activated sludge (WAS) from the extended
aeration process. The WAS from the extended aeration process is pumped on a weekly basis by
the operator the aerobic digester (250,000 gallons) for aerobic digestion. Aerobic conditions are
maintained by introducing oxygen through a floating aerator located in the digester. The aerator
provides sufficient air to keep the contents mixed and aerobic, allowing for solids digestion.
The digester is operated in a fill and decant mode whereas the tank is filled with WAS,the contents
aerated,the solids settled and decanted, and then the tank filled again. The operation decants once
every two weeks. Solids are stored in digester until the solids level reaches up to 2 — 3 feet of
freeboard, then the digester is emptied of its solids. The digester is emptied two to three every
year and hauled off-site by a licensed contractor(SynaGro) as a liquid for land application.
The West Stanly WWTP is to be expanded from a flow capacity of 1.2 MGD to 2.5 MGD. The
same sludge management process implemented now would continue to be used in the future. The
disposal contract arrangement between Stanly County and SynaGro will continue in the future as
it does today. To accommodate for the increase in the sludge wasting volume associated with the
WWTP plant expansion,the 50-ft secondary clarifier will be converted to an aerobic digester with
a volume of 205,600 gallons. In addition,an existing aeration basin is to be converted to an aerobic
digester as well. These additional digesters will be operated in a similar fashion as the existing
digester tank with cycles of fill, aeration, and decanting with the sludge hauler coming on-site to
haul away the liquid sludge. The additional digester volume will more than double the existing
digestion capacity and is sufficient for the future expansion.
