Subject: DRAFT NPDES PERMIT NC0051969
Castle Creek Memory Care WWTP
Grade II Biological Water Treatment Facility
[15A NCAC 08G.0302]
New Hanover County
Dear Mr.Trefzger:
Enclosed with this letter is a copy of the draft permit for your facility. Please review the draft very carefully
to ensure thorough understanding of the conditions and requirements it contains. Your permit is among
several in the Cape Fear River Basin that the Division has targeted for expedited renewal.
This draft contains the following changes from the existing permit:
• Updated facility description on supplement to cover page to include 12-digit HUC.
• Updated Section A.(2.)to include instructions for electronic submittal of WET results.
• Updated Section A.(3.)to be consistent with current federal requirements for electronic reporting
• Based on newly available in-stream and effluent hardness data,the limit for copper,a hardness-
dependent metal,has been re-calculated.New limits for copper are:
o Monthly Average: 50.13 µg/L
o Daily Maximum: 80.54 µg/L
• Copper monitoring frequency has been reduced to monthly,per RPA guidance.
• Monitoring for Zinc has been removed from the permitted effluent limits and monitoring
requirements,as this parameter did not demonstrate reasonable potential to exceed applicable
water quality standards.
The NPDES standard conditions(Parts II,III,and IV)that are a part of the permit are not included in this
draft document(cover,map,and Part I).The conditions are the same as in your current permit.The latest
version is available at https://bit.ly/2BZ4xxx and can be viewed online or downloaded as a PDF file.
With this notification,the Division will solicit public comment on this draft permit by publishing a notice
in newspapers having circulation in the general New Hanover County area,per EPA requirements.Please
provide your comments,if any,to me no later than 30 days after receiving this draft permit.
Following the 30-day public comment period, the Division will review all pertinent comments and take
appropriate action prior to issuing a final permit.If you have questions concerning the draft,please contact
me via email at[[e-mail]]or call 919-707-9125.

2. E=Effluent;U=Upstream--50 feet above outfall;D=Downstream—0.5 miles downstream of
outfall.
3. Total Residual Chlorine(TRC)limit and monitoring apply only if the Permittee uses chlorine or a
chlorine derivative to disinfect.The Division shall consider compliant all TRC values reported
below 50 µg/L.However,the Permittee shall continue to record and submit all values reported by a
North Carolina-certified test method,even if these values fall below 50 µg/L.
4. Chronic WET-Testing[THP3B]Pass/Fail using Ceriodaphuia dubia;effluent concentration at 90%,
during the months of January,April,July and October[see A.(2.)].

Permit NC0051969
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 pennittee 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 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.
A. (3.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS

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 pennittee 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.
