Subject: Draft NPDES Permit NC0078115
Greystone Subdivision WWTP
Grade II Biological WPCS
Forsyth County
Dear Ms. Berger:
Attached with this letter is a copy of the Draft NPDES permit renewal for your facility. Please review
this draft carefully to ensure thorough understanding of the requirements and conditions it contains. We
understand from your renewal application that there have been no treatment system changes. There are a
few changes in the draft attached here from the existing permit. These changes are summarized below.
• Regulatory Citations-Language has been added where necessary in the permit to provide regulatory
citations for permit requirements.
• Electronic Reporting-Permit language has been modified to be consistent with the finalization of
federal requirements for electronic reporting.
• Treatment System Components—The description of treatment components in the permit has been
updated to reflect the addition of well water treatment filter backwash that is now part of the system.
• Facility Location on Supplement Sheet—The street address of the facility has been corrected to
1549 Creek Bed Road
• Radiological Parameters of Concern Corrections—The six radiological parameters added to the
permit in the 2017 permit renewal included a sampling type of"Grab." In accordance with rule 15A
NCAC 2B .0505 this facility has design flow of over 30,000 GPD, so the sample type should be
"Composite." This change has been made in the draft permit. Additionally,the 2017 permit included
an incorrect limit for Strontium. In accordance with 15A NCAC 2B .0211 and Division policy,this
limit should have been set at 8 pCi/L. This change has been made in the draft permit.
• Changes based on Reasonable Potential Analysis(RPA)—The Division has utilized your submitted
DMR data to evaluate reasonable potential for the discharge of certain parameters to impact surface
waters. This analysis was done for the two effluent flow levels at their respective discharge locations.
Changes to the permit associated with these RPA evaluations are summarized here:

— For the 0.032 MGD effluent discharge at outfall 001:
o Copper and Zinc limits have been added to the permit in response to the RPA data showing
reasonable potential for impacts. Monitoring will be at a monthly frequency. A footnote has
been added to indicate that these limits will be effective two(2)years after the effective date
of the permit.
o Lead data showed no potential impact, so Lead monitoring requirements have been removed
from the permit.
— For the 0.185 MGD effluent discharge at outfall 002:
o Copper and Zinc limits have been added to the permit in response to the RPA data showing
reasonable potential for impacts. Monitoring will be at a monthly frequency. A footnote has
been added to indicate that these limits will be effective two(2)years after the effective date
of the permit.
o Lead and Chloride data showed no potential impact, so Lead and Chloride monitoring
requirements have been removed from the permit.
• Whole Effluent Toxicity(WET)Requirements—The 0.032 MGD WET monitoring requirements
have been corrected to reflect the 7Q10 flow of zero(0)at outfall 001. With an Instream Waste
Concentration(IWC)of 100%the WET test should be conducted at an effluent concentration of 90%
rather than the 38%that the previous permit include.This change has been made in the permit.
• Map Update—Descriptive information on the permit map has been updated.
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 of the standard conditions is available at https://bit.ly/3k5NFaL and can be viewed online or
downloaded as a PDF file.
Concurrent with this notification the Division is publishing a notice in a newspaper having general
circulation in the Forsyth County area soliciting public comments on this draft permit.
Please provide any written comments you may have to me no later than 30 days after receipt of 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 this draft permit,
please contact me by email at [e-mail]. At this time,contact by email is the most
effective method. If we need to set up a call to discuss any issues,we can set that up through email.

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:
