Subject: Request for Additional Information

NPDES permit NCO084425
Davidson County
Dear Mr. Sink:
On July 14, 2017, the Division of Water Resources (DWR) requested additional information on stream
flow data (7Q10/30Q22) and effluent Total Hardness data. Review of the 7Q10 data received on July 18,
2017 indicated no reasonable potential to exceed the new dissolved metal standards for Zinc and Copper.
Additionally, the reasonable potential analysis did not show reasonable potential to exceed the Total
Fluoride standard. Review of toxicity data for the last twelve (12) quarters indicated a 92% pass rate (11
out of 12) with no failures in the last four (4) quarters. Therefore, this conventional technology water
treatment plant is eligible for the for coverage under a general permit.
On August 1, 2014, the Division of Water Resources (DWR) issued a General Permit NPDES permit
(NCG590000) for wastewaters from Greensand and Conventional type water treatment plants. This
permit was developed to expedite the issuance and reissuance of these types of permits.
The Davidson Water, Inc.'s existing Individual NPDES permit for its Davidson Water Treatment Plant
(WTP) is up for modification and qualifies for coverage under this new General Permit. The annual
permit fee for the general permit is $100 verses $860 for an Individual permit and monitoring is less
frequent than that listed in your current permit.
Similar to Individual NPDES permits; general permits expire every five years but can be renewed by
completing a short and simple general permit renewal form. The General Permit is reissued every five
years and is sent to all the Permittees covered under it, all at the same time.
To switch to the General permit, the Permittee will need to make a written request to DWR. Please note,
the issuance of the General Permit would require the recession of your individual permit. The Division
suggests that you review the attached file containing the General Permit NCG590000 and decide whether
you would like the Division to modify the individual permit or proceed with issuance of the General
permit via a Certificate of Coverage for the WTP. Note that the Davidson WTP operates a conventional
water treatment system that discharges to freshwater, so the facility would be subject to the limitations
listed on page 5 (B. (3.) Conventional WTP Effluent Limitations and Monitoring Requirements —
Discharging to Freshwater) in the attached General permit.

To request that the Division proceed with issuing the General Permit instead of modifying the existing
Individual permit, Davidson Water, Inc should respond with something like the following:
Davidson Water, Inc has reviewed the Division of Water Resources General Permit
NCG5900000 for greensand and conventional type water treatment plants and
requests that the discharge from the Davidson WTP be covered under this new
general permit. Davidson Water, Inc understands that the Division will rescind the
individual NPDES permit for the Davidson WTP — NC0084425 when the Certificate
of Coverage for the General Permit NCG590000 is issued to Davidson Water, Inc for
the WTP
The written request shall be signed by an authorized Davidson Water, Inc official in accordance with
15A NCAC 0211.0 1 06(e).
If you have any questions concerning this matter, please contact me by email at
[e-mail] or by telephone at 919-807- 6307. Your representative(s) from Davidson
Water, Inc. are welcome to call and review the limitations in the General Permit with me as well.
Please let me know how you would like us to proceed within the next two weeks, preferably by
August 8, 2017. If we do not get a response the Division will proceed with the modification of the
Individual permit.
Sincerely,

Permit No NCG590000
(1.) Eligibility of Coverage
a Existing Greensand Water Treatment Plants (WTPs) with individual NPDES permits and new facilities seeking a
NPDES permit for a greensand water purification system utilizing Iron and/or Manganese removal systems are
eligible for coverage under this general permit. Backwash wastewaters from similar activities such as sand filtration
or systems utilizing calcite filtration Ere eligible and covered under the Greensand WTP effluent requirements section
in this general permit
b Existing Conventional WTPs with a wastewater discharge resulting from water purification facilities with filter
backwash, sedimentation basm washdown, and decant from water treatment facilities are eligible for coverage under
this general permit.
(2.) Limitations on Coverage
a. Although this general permit does not cover the following types of discharges, other permits such as an
individual NPDES permit, an alternate general permit, or other approval from the Division may be obtained
This permit does not authorize discharges from Water Treatment Plants with the following.
• Discharges that are mixed with o --her process wastewaters.
• Discharges to waters classified as High Quality Waters (HQW) or Outstanding Resource
Waters (ORW)
• Discharges from water purification systems using Membrane Treatment (Reverse Osmosis) or
Ion Exchange
• Discharges that would adversely affect a Federal or State listed endangered or threatened
species or its critical habitat.
• Discharges of pollutants to an impaired waterbody in excess of the wasteload allocation
specified in an EPA -Approved TMDL (Total Maximum Daily Load)
• Discharges from new Conventional WTPs proposing a discharge to surface waters.
b New Conventional WTPs proposing a discharge to surface waters shall be covered under an individual permit for
at least one permit cycle. Upon permit renewal, if an evaluation of the facility's wastewaters shows no need for
additional limitations or requirements beyond what is contained in this general permit, then the permittee will be
considered for coverage
c. Conventional WTPs proposing to expand existing facilities shall submit a Notice of Intent (NOI) permit
application with the proposed expansion/treatment details and an Engineering Alternative Analysis for Division
review and approval in order to obtain coverage for the expansion under this permit and receive a revised
Certificate of Coverage (CoC)

expected to be contributing to a violation of a water quality standard (as defined in the "Red Book" or NC
Administrative Code 15A NCAC 02B .0 100, 0200, and .0300).
e If the Division determines at any time that the discharge is causing or contributing to a violation of water quality
standards or if the Division has any other grounds for modifying or revoking this permit, the Division may require
corrective action or require the discharge be permitted differently in accordance with Part II, Section B of this
permit. The Division may deny coverage under this permit and require submittal of an application for an
individual NPDES permit based on a review of the Notice of Intent (NOI) or other information.
f. Whole Effluent Toxicity (WET) test results for the past three years shall be reviewed for existing or
expanding Conventional WTPs applying for coverage under this general permit. Permittees with WET test
results showing potential for aquatic toxicity may be denied coverage under this general permit which
includes a WET limitation of "Pass"
(3.) Transfer Coverage from Other Permits
Upon issuance of this general permit, all existing and active individual permits for Greensand and
Conventional type WTPs will automatically be considered for coverage under this general permit as

C. ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
Proposed 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 Division anticipates that these regulations will
be adopted and is beginning implementation in late 2013
NOTE: This special condition supplements or supersedes the following sections within Part H of this permit
(Standard Conditions for NPDES Permits)'
• Section B. (11.) Signatory Requirements
• Section D (2.) Reporting

Beginning no later than 270 days from the effective date listed on the Certificate of Coverage issued with this
permit, the permittee shall begin reporting discharge monitoring data electronically using the NC DWR's
Electronic Discharge Monitoring Report (eDMR) internet application
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 monthly DMRs electronically using the internet. 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 DENR / DWR / Information Processing Unit
ATTENTION. Central Files / eDMR
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.
Requests for temporary waivers from the NPDES electronic reporting requirements 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 using eDMR. Temporary waivers shall be valid for twelve (12) months
and shall thereupon expire At such time, DMRs shall be submitted electronically to the Division unless the
permittee re -applies for and is granted a new temporary waiver by the Division
Information on eDMR and application for a temporary waiver from the NPDES electronic reporting
requirements is found on the following web page.
http://portal ncdenr.org/web/wq/admm/bog/ipu/edmr
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
