Dear Mr. Grimaldi:
The Division of Water Resources (the Division)hereby issues the attached NPDES permit for
the subject 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.
We have made the following updates to your previous permit:
• added parameter codes to Section A. (1.)
• updated facility description has been modified to better reflect the operational circumstances
of the facility, including the typical frequency and duration of discharge
• pursuant to a review of data reported during the current permit cycle,including performance
of a reasonable potential analysis upon applicable parameters (Chloride, Copper and Zinc),
monitoring frequency has been reduced from monthly to quarterly for the following
parameters: Total Dissolved Solids,Turbidity,Total Copper,Total Zinc, Total Nitrogen and
Total Phosphorous
• monitoring for pH has been reduced from 2/month to monthly
• monitoring for Total Chlorides has been removed from the permit
• added Discharge Alternatives Evaluation as described in Section A. (2.).
Whole Effluent Toxicity test results submitted during the past three years have demonstrated
that the Water Treatment Plant's effluent is showing potential for causing aquatic toxicity in
the receiving stream. As a result, the Daniel Jonathan Stowe Conservancy shall perform a
Discharge Alternatives Evaluation as described in Section A. (2.) of this permit. This
• evaluation is being requested to determine whether there are any economical and
technologically feasible alternatives available to the Daniel Jonathan Stowe Conservancy to
comply with all NC Water Quality Standards.The permittee will be given approximately one
permit cycle to evaluate and document possible treatment/discharge alternatives to eliminate
aquatic toxicity. The evaluation shall be submitted with the permittee's next permit renewal
application and will be carefully reviewed by the Division and the results will be used in the

development of a compliance schedule or possible variance request for the Daniel Jonathan
Stowe Conservancy. ,
We have made the following updates since the draft permit:
• updated stream inform an unnamed tributary to Catawba River (Lake Wylie) [Stream
Segment 11-(123.5)] classified WS-V, B waters (the previous permit and BIMS database
indicated that the stream was Catawba Creek [Stream Segment 11-130] classified C waters
which was incorrect)
• updated the facility map
• the coordinates for the Outfall 001 were adjusted to the following:
Latitude: 35° 10' 13" Longitude: -81° 03' 18"
• updated footnote 1 in Section A. (1.): Effective December 21,2016,the permittee shall
report discharge monitoring data electronically using the NC DWR's Electronic Discharge
Monitoring Report(eDMR)internet application. See Special Condition A. (4.).
• updated Special Condition A. (4.)for electronic reporting of monitoring reports
• removed Salinity monitoring because this parameter is intended for RO water treatment
systems that typically are found near the coast in which there is a narrative water quality
standard for saltwater
• added a 500 mg/L limit with monthly monitoring for Total Dissolved Solids because
Catawba River(Lake Wylie) is classified as WS-V, B waters.
Starting December 21, 2016, federal regulations require electronic submittal of all discharge
monitoring reports (DMRs)and specify that, if a state does not establish a system to receive such
submittals, then permittees must submit DMRs electronically to the Environmental Protection
Agency(EPA). The final NPDES Electronic Reporting Rule was adopted and became effective
on December 21, 2015.
The requirement to begin reporting discharge monitoring data electronically using the NC
DWR's Electronic Discharge Monitoring Report(eDMR)internet application has been added to
your final NPDES permit. [See Special Condition A. (4.)] For information on eDMR,
registering for eDMR and obtaining an eDMR user account,please visit the following web page:

NPDES Permit NC0088684
A. (2.) DISCHARGE ALTERNATIVES EVALUATION [15A NCAC 02H .0105]
The Permittee shall assess potential alternatives to eliminate Whole Effluent Toxicity(WET)test failures.
This evaluation shall assess the feasibility of all the following alternatives.
1. Connect discharge to a WWTP: Determine whether the wastewater can be discharged to a
wastewater treatment plant. Approval or disapproval from the plant operator should
be acquired.
2. Obtain a Non-discharge permit: Eliminate the surface water discharge by obtaining a non-discharge
permit for spray irrigation, infiltration, or subsurface disposal (on-site drainfield,
infiltration gallery, injection wells).
3. Install Wastewater Treatment: Install improved wastewater treatment to enable the facility effluent
to consistently pass the WET test. If this is not technically feasible or cost
prohibitive,please explain and provide estimated costs.
4. Use Alternative Water Treatment Source: Obtain drinking water from another source (nearest
County, City, or Town or other wells) so the discharge or toxicity problem is
eliminated.
5. Use Alternative Water Treatment Method: Install alternative and/or innovative water treatment
methods or operational improvements that do not produce toxic wastewaters. For
example, install a recycle iron/manganese filtration system with no discharge or
combine discharge with WWTP or cooling water effluents.
6. Discharge to a Larger waterbody/Perform a dilution model: Relocate the facility's discharge to a
larger receiving waterbody to eliminate or reduce toxic impacts to the receiving
waterbody given the increased dilution. If applicable,perform a dilution model to
receive allowance for stream dilution in WET test.
7. Combination of Alternatives: Employ any combination of the alternatives listed above that would
result in eliminating or decreasing toxicity until a more feasible solution becomes
available.
The evaluation shall include a present value of costs analysis for all technologically feasible options as
outlined in the Division's "Engineering Alternatives Analysis Guidance Document."This Document can be
found at: http://portal.ncdenr.org/web/wq/swp/ps/npdes/permits.
This evaluation is being requested to determine whether there are any economical and technologically
feasible alternatives available to the Permittee to address aquatic toxicity in the plant effluent. Based upon
the evaluation,please identify viable alternatives and present an implementation schedule and project
timeline for the preferred alternative. The Permittee shall submit the Discharge Alternatives Evaluation to
the Division along with the submission of their next permit renewal application(due 6 months prior to
permit expiration on August 31, 2020) to:

NPDES Permit NC0088684
A. (3.) CHRONIC TOXICITY PASS/FAIL MONITORING ONLY (QUARTERLY)
[15A NCAC 02B .0500 et seq.]
The permittee shall conduct quarterly chronic toxicity tests using test procedures outlined in the"North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure,"Revised December 2010, or subsequent
versions.
The effluent concentration defined as treatment two in the procedure document is 90 %. The testing
shall be performed as a Ceriodaphnia dubia 7-day pass/fail test. 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 during representative effluent discharge and shall be performed at the NPDES
permitted final effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form(MR-1) for the month in which it was performed, using the parameter
code TGP3B. Additionally, DWR Form AT-1 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1623 Mail Service Center
Raleigh,North Carolina 27699-1623
Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Section no later than 30
days after the end of the reporting period for which the report is made.
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. 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, then
monthly monitoring will begin immediately. Upon submission of a valid test,this monthly test
requirement will revert to quarterly in the months specified above.
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 controls,
shall constitute an invalid test and will require immediate follow-up testing to be completed no later
than the last day of the month following the month of the initial monitoring.

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: http://www2.epa.gov/compliance/final-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.

calendar day for purposes of sampling. For pollutants measured in units of mass,the "daily discharge"is calculated as
the total mass of the pollutant discharged over the day. For pollutants expressed in other units of measurement,the
"daily discharge"is calculated as the average measurement of the pollutant over the day. (40 CFR 122.2; see also
"Composite Sample,"above.)
Daily Maximum
The highest"daily discharge"during the calendar month.
Daily Sampling
Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the
permit. Sampling shall be conducted on weekdays except where holidays or other disruptions of normal operations
prevent weekday sampling. If sampling is required for all seven days of the week for any permit parameter(s),that
requirement will be so noted on the Effluent Limitations and Monitoring Page(s).

Condition A(3).
All samples must be collected from a typical discharge event.
There shall be no discharge of floating solids or visible foam in other than trace amounts.
A. (2.) Permit Re-Opener: Whole Effluent Toxicity Monitoring
Whole Effluent Toxicity monitoring results indicating aquatic toxicity failure may result in the
Division of Water Quality re-opening this permit,requesting by letter that further action be taken.
Additional metals testing and/or toxicity identification/reduction evaluations may be requested
to determine the cause(s) of the effluent toxicity and to reduce effluent loading to acceptable
levels.

Permit NC0088684
A. (3.) CHRONIC TOXICITY MONITORING (QUARTERLY)
The permittee shall conduct quarterly chronic toxicity tests using test procedures outlined in the
"North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure,"Revised February 1998, or
subsequent versions.
The effluent concentration defined as treatment two in the procedure document is 90 %. The
permit holder shall perform quarterly monitoring using this procedure to establish compliance
with the permit condition. The tests will be performed during the months of March, June,
September and December. Effluent sampling for this testing shall be performed at the NPDES
permitted final effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was performed, using the
parameter code TGP3B. Additionally, DWQ Form AT-1 (original) is to be sent to the following
address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh,N.C. 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section
no later than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete and accurate and include all supporting chemical/physical
measurements performed in association with the toxicity tests, as well as all dose/response data.
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 Environmental Sciences Section at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required,
then monthly monitoring will begin immediately. Upon submission of a valid test, this monthly
test requirement will revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Water Quality 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 controls, shall constitute an invalid test and will require immediate follow-up
testing to be completed no later than the last day of the month following the month of the initial
monitoring.

Calendar Quarter
One of the following distinct periods: January through March,April through June,July through September,and
October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 mL in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period.The
Director may designate the most appropriate method(specific number and size of aliquots necessary, the time interval
between grab samples, etc.)on a case-by-case basis. Samples may be collected manually or automatically. Composite
samples may be obtained by the following methods:
(I) Continuous: a single,continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24 hour period
of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection,or
(3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period with
the time intervals between samples determined by a preset number of gallons passing the sampling point. Flow
measurement between sample intervals shall be determined by use of a flow recorder and totalizer,and the
preset gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at
the treatment system,or
Version 11/09/2011

NPDES Permit Standard Conditions

NPDES Permit No.: NC0088684
PART I - GENERAL INFORMATION
1. Facility and address: Daniel Stowe Botanical Garden
6500 South New Hope Road
Belmont,NC 28012
2. Date of investigation: April 21, 2010
3. Report prepared by: Michael L. Parker, Environmental Engineer II
4. Person contacted and telephone number: Eric Woodward, [phone]
5. Directions to site: The entrance to the Daniel Stowe Botanical Gardens is located on
Highway 279 (South New Hope Road) z 1/2 mile north of the junction of Hwy. 279 and
Hwy. 273 (Armstrong Road) in southern Gaston County.
6. Discharge point(s), list for all discharge points:
Latitude: 35° 09' 34"
Longitude: 80° 03' 06"
Attach a USGS Map Extract and indicate treatment plant site and discharge point on map.
USGS Quad No.: G14NE
7. Receiving stream or affected surface waters: UT to Catawba Creek(Lake Wylie)
a. Classification: WS-IV
b. River Basin and Subbasin No.: Catawba 030837
c. Describe receiving stream features and pertinent downstream uses: The receiving
stream is a dry ditch at the point of discharge,which is dominated by storm water
flow during periods of wet-weather. There are no other downstream dischargers
known.

Page Two
PART II -DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
1. a. Volume of wastewater: 0.0038 MGD (Design Capacity)
b. What is the current permitted capacity:N/A(Intermittent)
c. Description of existing or substantially constructed WWT facilities: There are no
existing WWT facilities.
d. Description of proposed WWT facilities: The applicant does not plan to construct
WWT facilities at this time, however the wastewater is generated from a reverse
osmosis water treatment system that includes the use of a water softener.
e. Possible toxic impacts to surface waters: There are no toxic impacts are
expected,however,the permittee has experienced difficulty in complying with the
toxicity testing requirement due to the fact the discharge enters a dry ditch and
testing must be performed at 90% concentration.
PART III- OTHER PERTINENT INFORMATION
1. Special monitoring or limitations (including toxicity)requests: The current permit
contains upstream and downstream monitoring (no limits) for temperature, salinity,
conductivity, DO, and pH. As mentioned in Part I,No. 7 above,this discharge enters a
storm water drainage channel that typically only carries flow during storm events.
During the majority of the year, this channel is dry for a distance of several hundred feet
below the point of discharge except during storm events. For that reason, instream
collection of the above noted parameters when channel flow is predominately a storm
event would likely not provide any useful WQ data in which to base compliance with WQ
standards. Prior to permit reissuance, a determination should be made as to the necessity
of continuing instream monitoring in the renewed permit.
2. A review of self-monitoring data noted the presence of copper in the waste stream at
levels well above the 5.0 ug/1 water quality standard for this parameter. A
possible source of the copper in the effluent may be the copper piping used in the
construction of the RO treatment system,however,there may be other sources as well. At
low pHs, metals (copper and lead in particular) have been known to leach out from metal
piping,however, effluent pH levels at this facility are well above the 6.0 standard units
set forth in the permit. Zinc was also found in the effluent at levels well above the 50
ug/1 action level set forth in our Rules. Given the lack of receiving waters at the point of
discharge (see No. 1 above), it is not anticipated that either copper or zinc are creating a
negative effect on downstream surface waters.

Page Three
PART IV- EVALUATION AND RECOMMENDATIONS
The Daniel Stowe Botanical Garden discharges up to 3800 gpd of wastewater from a
reverse osmosis (RO) ground water treatment system that is used to produce water for plant
irrigation and a high pressure misting system. The RO system is primarily designed to remove
mineral deposits found in the ground water so it can be used on specific plants grown at the
Garden. There are no changes to the permit being requested at this time by the permittee.
Changes suggested by the RO are addressed in Part III above. •
Pending a final review by the NPDES Unit, it is recommended that the permit be reissued
as requested. .

Dear Mr. Wood:
The Division received a request to modify the subject permit to correct an error by replacing the
Whole Effluent Toxicity (WET)testing requirement. Enclosed with this letter is a replacement for Part I
A. (2) of the NPDES permit for the Daniel Stowe Botanical Garden issued on January 23, 2008. Please
replace the original Part I A. (2) with the attached new version. The new version of the WET testing
requires Daniel Stowe Botanical Garden to perform monitoring only.
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 other permits which may be required by the Division of Water Quality or
permits required by the Division of Land Resources,the Coastal Area Management Act or any other
Federal or Local governmental permit that may be required.
If you have any questions or comments concerning this draft permit, you may contact me at the

A.(2)CHRONIC TOXICITY MONITORING ONLY(QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 90%.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in
the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or
subsequent versions or"North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"(Revised-
February 1998) or subsequent versions. The tests will be performed during the months of March, June,
September and December. Effluent sampling for this testing 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 below
the permit limit, then multiple-concentration testing shall be performed at a minimum, in each of the two
following months, as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure"(Revised-February 1998)or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the
highest concentration having no detectable impairment of reproduction or survival and the lowest
concentration that does have a detectable impairment of reproduction or survival. The definition of
"detectable impairment," collection methods, exposure regimes, and further statistical methods are specified
in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised-February 1998)
or subsequent versions. All toxicity testing results required as part of this permit condition will be entered on
the Effluent Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the
parameter code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally,DWQ Form
AT-3 (original) is to be sent to the following address:
Attention: NC DENR/DWQ/Environmental Sciences Section
1621 Mail Service Center
Raleigh,North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no
later than 30 days after the end of the reporting period for which the report is made.
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 Environmental
Sciences Branch 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. Should any test data from this monitoring
requirement or tests performed by the North Carolina Division of Water Quality 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 controls,
shall constitute an invalid test and will require immediate follow-up testing to be completed no later than
the last day of the month following the month of the initial monitoring.

the Effluent Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the
parameter code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally,DWQ Form
AT-3 (original) is to be sent to the following address:
Attention: NC DENR/DWQ/Environmental Sciences Section
1621 Mail Service Center
Raleigh,North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no
later than 30 days after the end of the reporting period for which the report is made.
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 Environmental
Sciences Branch 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. Should any test data from this monitoring
requirement or tests performed by the North Carolina Division of Water Quality 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 controls,
shall constitute an invalid test and will require immediate follow-up testing to be completed no later than
the last day of the month following the month of the initial monitoring.

Act or"the Act"
The Federal Water Pollution Control Act,also known as the Clean Water Act,as amended,33 USC 1251,et. seq.
Annual Average
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal
coliform,the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
Bypass
The known diversion of waste streams from any portion of a treatment facility including the collection system,which
is not a designed or established or operating mode for the facility.
Calendar Day
The period from midnight of one day until midnight of the next day. However, for purposes of this permit, any
consecutive 24-hour period that reasonably represents the calendar day may be used for sampling.
Calendar Quarter
One of the following distinct periods: January through March, April through June, July through September, and
October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 ml in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time
interval between grab samples, etc.) on a case-by-case basis. Samples may be collected manually or automatically.
Composite samples may be obtained by the following methods:
(1) Continuous: a single,continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24 hour
period of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection,or
(3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period
with the time intervals between samples determined by a preset number of gallons passing the sampling
point. Flow measurement between sample intervals shall be determined by use of a flow recorder and
totalizer, and the preset gallon interval between sample collection fixed at no greater than 1/24 of the
expected total daily flow at the treatment system,or
(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at
a constant time interval. Use of this method requires prior approval by the Director. This method
may only be used in situations where effluent flow rates vary less than 15 percent. The following
restrictions also apply:

monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance
activities on the flow device.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass,the "daily discharge"is calculated as
the total mass of the pollutant discharged over the day. The "daily discharge" concentration comprises the mean
concentration for a 24-hour sampling period as either a composite sample concentration or the arithmetic mean of all
grab samples collected during that period. (40 CFR 122.2)
Daily Maximum
The highest "daily discharge" for conventional and other non-toxicant parameters. NOTE: Permittees may not
submit a "daily average" calculation [for determining compliance with permit limits] for toxicants. See the relevant
Federal effluent guideline[s] for the appropriate calculation interval.
Daily Sampling
Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the
permit. The Division expects that sampling shall be conducted on weekdays except where holidays or other

North Carolina Division of Water Quality/NPDES Unit
512 N. Salisbury St.
Raleigh,North Carolina 27604
RE: Daniel Stowe Botanical Garden—Reverse Osmosis System,Return No.2253,Gaston County
SUBJECT: Engineering Alternatives Analysis
Dear Mrs.Rodriguez:
Using the Division of Water Quality's Engineering Alternatives Analysis(EAA)Guidance Document it has been
concluded that a direct discharge to surface water is the most environmentally sound,cost-effective alternative for
removal of the reverse osmosis wastewater created at Daniel Stowe Botanical Garden's Orchid Conservatory.
A reverse osmosis(RO) water purification system is being installed as part of the construction of an Orchid
Conservatory at Daniel Stowe Botanical Garden. The conservatory is approximately 8,000 SF, with a 1,600 SF
support building attached. The RO system is used to purify water used to hand-water plants inside the conservatory,
as well as supply water for the high pressure misting system overhead,used to provide additional moisture to the air
within the conservatory. Non-municipal flow projections based on peak use from the misting and hand-watering
operations are 3,800 GPD,creating a reject flow of 3,800 GPD.
An evaluation of the technologically feasible alternatives included: connecting to existing wastewater treatment
system,wastewater reuse methods,and direct discharge to surface waters. The existing wastewater treatment
system is a private septic system on Daniel Stowe Botanical Garden property and is designed for 5,000 GPD. The
addition of 3,800 GPD would overwhelm this system,making this alternative infeasible. The reuse of the
wastewater as irrigation is also not feasible as the garden already has an extensive irrigation system used for
watering its wide variety of plants,including many non-indigenous plants,which would react poorly the RO
wastewater. This leaves the direct discharge to surface waters as the only technologically feasible alternatives.
This RO system is simply treating potable well water pumped from a well on Daniel Stowe Botanical Garden
property to the RO system in order to create purified water which will work in the high-pressure misting system
without creating calcium deposits on the high-pressure nozzles,which would lead to maintenance issues and system
failure. This wastewater will not have any oxygen-consuming waste. The system requires 2 gallons of water to
create 1 purified gallon. Based on the potential restrictions to a wastewater discharge to surface water listed in the
EAA Guidance Document,we have determined that this reverse osmosis wastewater discharge will be allowed.
Sincerely,
eatz...(2
