Application for Authorization to Construct
Dear Mr.Lentz,
Please consider this information as support for an Authorization to Construct (AtC)
application for a Hycor Hydroscreen Static Screen to serve the Salem Quarters WWTP.
This is a private facility and will not be publically bid. The facility address is 6961
Rangecrest Rd,Belews Creek,NC 27009 and is located in Forsyth County. The facility is
served by an existing wastewater treatment plant that is covered under Individual Permit
NC0083933. The existing permit has a permitted flow of 60,000 gpd. This AtC application
is being submitted to aid the existing wastewater treatment plant screen and should be
considered as a maintenance activity and associated process modification. There is no
change requested to the permitted flow and as such is not a new or expanding system.
The new Hydroscreen consists of the HS 18DF Hycor Hydroscreen Static Screen. The
Hycor Hydroscreen unit is a proven, reliable performer for liquid/solid separation in
municipal and industrial applications, particularly for screening fibrous and non-greasy
solids. There are no moving parts, motors, or complicated connections. The Hydroscreen
is simple and economical to operate.

DocuSign Envelope ID 0050B388-53E6-4303-A498-FFAOEDE9E8CB
The new system will be constructed in a single phase with an estimated construction
timeline of 30 days. Construction commencement will occur following issuance of the
Authorization to Construct and ideally occurs prior to the end of calendar year 2023. The
existing wastewater treatment plant screen will continue operating during construction of
the new plant. The existing screen will be maintained to act as an overflow if needed.

A. (2) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
[NCGS 143-215.1 (b)]
Federal regulations require electronic submittal of all discharge monitoring reports(DMRs) and program
reports. The final NPDES Electronic Reporting Rule was adopted and became effective on December
21, 2015.
NOTE: This special condition supplements or supersedes the following sections within Part II of this
permit(Standard Conditions for NPDES Permits):
• Section B. (11.) Signatory Requirements
• Section D. (2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports
1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)1
The permittee shall report 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 DMRs electronically using the internet. The eDMR system may be
accessed at: https://deq.nc.gov/about/divisions/water-resources/edmr.
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
following address:
NC DEQ/Division of Water Resources/Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
See "How to Request a Waiver from Electronic Reporting" section below.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
reported via the eDMR system no later than the last calendar day of the month following the
completed reporting period. 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.

Permit NC0083933
Starting on December 21, 2025 the permittee must electronically report the following compliance
monitoring data and reports, when applicable:
• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports; and
• Clean Water Act (CWA) Section 316(b)Annual Reports.
The permittee may seek an electronic reporting waiver from the Division (see "How to Request a
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: https://www.federalregister.gov/documents/2015/10/22/2015-
24954/national-pollutant-disch arge-eli mination-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.
Information on eDMR and the application for a temporary electronic reporting waiver are found on
the following web page:
http://deq.nc.gov/about/divisions/water-resources/edmr

Salem Quarters wastewater treatment plant.The existing inlet line and bar screen will be maintained
as part of the project. To direct flow to the new Hydroscreen, a"doghouse"style manhole will be
installed on the existing inlet line with a new drainline leading to the new Hydroscreen unit. To
minimize any overflow from the Hydroscreen unit, it will be located over the flow equalization
portion of the existing treatment plant.
Construction of the new Hydrosceen unit will not require a shutdown of the existing plant. The
existing plant will continue normal operation through the construction process.
1.2 Site Description
The project site consists of the property located at 6961 Rangecrest Road, Belews Creek,NC
27009 in Forsyth County(Parcel ID#6879-20-4699). The new Hydroscreen will be installed at
the inlet of the wastewater treatment plant.
1.3 Adjacent Property
The surrounding area at the wastewater treatment plant site is suburban and occupied by primarily
single-family residences.

gloves,goggles,kitty litter,sand,sawdust,and plastic and metal trash containers specifically for
this purpose.
• All spills will be cleaned up immediately after discovery.
• The spill area will be kept well ventilated, and personnel will wear appropriate protective
clothing to prevent injury from contact with a hazardous substance.
• Spills of toxic or hazardous material will be reported to the appropriate state or local government
agency, regardless of size.
• The spill prevention plan will be adjusted to include measures to prevent this type of spill from
reoccurring and how to clean up the spill if there is another one. A description of the spill,what
caused it, and the cleanup measures will also be included.

3.0 Site Work
The site shall be maintained in an orderly and clean fashion. Debris should be confined to a
common area and removed weekly. The minimum area needed shall be disturbed. Due to the small
footprint of the project, a formal erosion and control plan has not been developed. However,the
contractor shall follow standard practices to minimize any adverse effects from the installation of the
system.
3.1 Construction Roads and Parking
Construction roads and parking areas are to be inspected periodically for the condition of surface.
Top-dress with new gravel as needed. Check areas for erosion and sedimentation after runoff-
producing rains.Maintain all vegetation in a healthy,vigorous condition.Sediment-producing areas
should be treated immediately.
3.2 Tree Preservation and Protection
Some clearing of trees will be required for the installation of the drain line connecting the facility to
the treatment unit. Care shall be taken to minimize the disturbed area during installation. Despite
precautions, some damage to protected trees may occur. In such cases, repair any damage to the
crown,trunk, or root system immediately.
Repair roots by cutting off the damaged areas and painting them with tree paint.Spread peat
moss or moist topsoil over exposed roots.
Repair damage to bark by trimming around the damaged area as shown in Figure 1 below,
taper the cut to provide drainage, and paint with tree paint.
Cut off all damaged tree limbs above the tree collar at the trunk or main branch. Use three
separate cuts as shown in Figure 2 to avoid peeling bark from healthy areas of the tree.

3.3 Removal of Topsoil
MATERIALS
Determine whether the quality and quantity of available topsoil justifies selective handling.Quality
topsoil has the following characteristics:
Texture-loam, sandy loam, and silt loamy are best; sandy clay loam, silty clay loam,clay
loam,and loamy sand are fair.Do not use heavy clay and organic soils such as peat or muck
as topsoil.
Organic matter content-(sometimes referred to as"humic matter")should be greater than
1.5%by weight.
Acidity-pH should be greater than 3.6 before liming,and liming is required if it is less than
6.0.
Soluble salts-should be less than 500 ppm.
Sodium-sodium adsorption ratio should be less than 12.The depth of material meeting the
above qualifications should be at least 2 inches. Soil factors such as rock fragments, slope,
depth to water table, and layer thickness affect the ease of excavation and spreading of
topsoil. Generally, the upper part of the soil, which is richest in organic matter, is most
desirable;however,material excavated from deeper layers may be worth storing if it meets
the other criteria listed above. Organic soils such as muck and peats do not make good
topsoil. They can be identified by their extremely light weight when dry.
SITE PREPARATION
Before spreading topsoil,establish erosion and sedimentation control practices such as diversions,
and berms as needed.
Grading-Maintain grades on the areas to be topsoiled according to the approved plan and
do not alter them by adding topsoil.
- Limit of subsoil-Where the pH of the existing subsoil is 6.0 or less,or the soil is composed
of heavy clays,incorporate agricultural limestone in amounts recommended by soil tests or
specified for the seeding mixture to be used. Incorporate lime to a depth of at least 2 inches
by disking or raking.
Roughening-Immediately prior to spreading the topsoil,loosen the subgrade by disking or
scarifying to a depth of at least 4 inches,to ensure bonding of the topsoil and subsoil.If no
amendments have been incorporated, loosen the soil to a depth of at least 6 inches before
spreading topsoil.
