Dear Mr. Paul.
The Wilmington Regional Office received a complete 8 year Stormwater Management Permit Renewal Application for
the subject project on June 2, 2020. The Division is hereby notifying you that permit SW8 060137 has been renewed on
July 9, 2020, and shall be effective until September 29, 2027. For your records, please find enclosed a renewed,
updated, and re -issued permit and a copy of the renewal application. Please keep this permit on file at all times. Please
note that the renewed, updated, and re -issued permit does not impose new or different terms; it merely restates some of
the previous terms to provide you with a better understanding of your obligations under the permit.
The renewal and reissuance of this stormwater permit does not imply that the site is currently in compliance with the
terms and conditions of this state stormwater permit. The plans originally approved on September 29, 2005 and most
recently revised on December 18, 2008, will remain in full force and effect in accordance with the regulations set forth
in Title 15A NCAC 2H.1000.
This permit is subject to the conditions and limitations as specified therein. Please pay special attention to the
conditions listed in this permit regarding the Operation and Maintenance of the BMP(s), recordation of deed
restrictions, procedures for changes of ownership, transferring the permit, and renewing the permit. Failure to establish
an adequate system for operation and maintenance of the stormwater management system, to record deed restrictions,
to transfer the permit, or to renew the permit, will result in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to request an
adjudicatory hearing by filing a written petition with the Office of Administrative Hearings (OAH). The written
petition must conform to Chapter 150E of the North Carolina General Statutes and must be filed with the OAH within
thirty (30) days of receipt of this permit. You should contact the OAH with all questions regarding the filing fee (if a
filing fee is required) and/or the details of the Fling process at 6714 Mail Service Center, Raleigh, NC 27699-6714, or
via telephone at 919-431-3000, or visit their website at www.NCOAH.com. Unless such demands are made this permit
shall be final and binding.
If you have any questions, need additional copies of the permit or approved plans, please contact Daniel Sams in the
Wilmington Regional Office, at [phone] or [e-mail].

Footnotes:
When using the Division SA/DA tables, the correct SAIDA ratio for permanent pool sizing should be computed based upon the
actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct -value for non-
standard table entries.
In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide,
90% TSS removal. The NCDENR DMP manual provides design tables for both 85% TSS removal and 90% TSS removal.

OPERATION
The Vortechs Stormwater. Treatment System is a hydrodynamic separator designed to
enhance gravitational separation of floating and settling materials from stormwater
flows. Stormwater flows enter the unit tangentially to the grit chamber, which promotes a
gentle swirling motion. As polluted water circles within the grit chamber, pollutants
migrate toward the center of the unit where velocities are the lowest. The majority of
setilable solids are left behind as stormwater exits the grit chamber through two
apertures on the perimeter of the chamber. Next, buoyant debris and oil and grease are
separated from water flowing under the baffle wall due to their relatively low specific
gravity. As stormwater exits the System through the flow control wall and ultimately
through the outlet pipe, it is relatively free of floating and settling pollutants.
Over time a conical pile tends to accumulate in the center of the unit containing
sediment and associated metals, nutrients, hydrocarbons and other pollutants. Floating
debris and oil and grease form a floating layer trapped in front of the baffle wall.
Accumulation of these pollutants can easily be assessed through access manholes over
each chamber. Maintenance is typically performed through the manhole over the grit
chamber.
MAINTENANCE
The Vortechs System should be inspected at regular intervals and maintained when
necessary to ensure optimum performance. The rate at which the System collects
pollutants will depend more heavily on site activities than the size of the unit, e.g.,
unstable soils or heavy winter sanding will cause the grit chamber to fill more quickly but
regular sweeping will slow accumulation.
INSPECTION
Inspection is the key to effective maintenance and is easily performed. Vortechnics
recommends ongoing quarterly inspections of the accumulated sediment. Pollutant
deposition and transport may vary from year to year and quarterly inspections will help
insure that Systems are cleaned out at the appropriate time. Inspections should be
performed more often in the winter months in climates where sanding operations may
lead to rapid accumulations, or in equipment washdown areas. It is very useful to keep a
record of each inspection. A simple form for doing so is attached herewith.
The Vortechs System should be cleaned when inspection reveals that the sediment
depth has accumulated to within six inches of the dry -weather water surface elevation.
This determination can be made by taking 2 measurements with a stadia rod or similar
measuring device; one measurement from the manhole opening to the top of the
sediment pile and the other from the manhole opening to the water surface. The System
should be cleaned out if the difference between the two measurements is six inches or
less. Note: To avoid underestimating the volume of sediment in the chamber, the
measuring device must be lowered to the top of the sediment pile carefully. Finer, silty
particles at the top of the pile typically offer less resistance to the end of the rod than
larger particles toward the bottom of the pile.

CLEANING
Maintaining the Vortechs System is easiest when there is no flow entering the System. For
this reason, it is a good idea to schedule the cleanout during dry weather. Cleanout of
the Vortechs System with a vacuum truck is generally the most effective and convenient
method of excavating pollutants from the System. If such a truck is not available, a
..clamshell" grab may be used, but it is difficult to remove all accumulated pollutants
with such devices.
In Vortechs installations where the risk of large petroleum spills is small, liquid
contaminants may not accumulate as quickly as sediment. However, an oil or gasoline
spill should be cleaned out immediately. Motor oil and other hydrocarbons that
accumulate on a more routine basis should be removed when an appreciable layer has
been captured. To remove these pollutants, it may be preferable to use adsorbent pads
since they are usually cheaper to dispose of than the oil water emulsion that may be
created by vacuuming the oily layer. Trash can be netted out if you wish to separate it
from the other pollutants.
Accumulated sediment is typically evacuated through the manhole over the grit
chamber. Simply remove the cover and insert the vacuum hose into the grit chamber.
As water is evacuated, the water level outside of the grit chamber will drop to the same
level as the crest of the lower aperture of the grit chamber. It will not drop below this
level due to the fact that the bottom and sides of the grit chamber are sealed to the
tank floor and walls. This "Water Lock" -feature prevents water from migrating into the grit
chamber, exposing the bottom of the baffle wall. Floating pollutants will decant into the
grit chamber as the water level there is drawn down. This allows most floating material to
be withdrawn from the some access point above the grit chamber.
If maintenance is not performed as recommended, sediment may accumulate outside
the grit chamber. If this is the case, it may be necessary to pump out all chambers. It is a
good idea to check for accumulation in all chambers during each maintenance event
to prevent sediment build up there.
Manhole covers should be securely seated following cleaning activities, to ensure that
surface runoff does not leak into the unit from above.

Design Storm Runoff Volume (WQV)
I Percent Impervious (Ai)
Ai = 100 x Imp Area/DA = 100 x 1.05/1.81 = 58%
2 Weighted Volumetric Runoff Coefficient (Rv)
Rv = 0.009 x Ai + 0.05 = (0.009 x 58) + 0.05 = 0.57 in/in
3 Design Storm Runoff Volume Depth (Qa)
P = Rainfall Depth = 1 '/2 in
Qa = P x Rv = (1.5 x 0.57) = 0.86 in
4 Design Storm Runoff Volume (WQV)
WQV =QaxDA=(0.86inx 1.81 ae)x(1 ft/12in)
WQV = 0.13 ac-ft = 5650 cu ft
Design Storm Peak Runoff Rate
1 Correlate a TR-55 CN for the Design Storm
CN = 1000/[10 + 5(P) + 10(Qa) — 10(Qa2 + 1.25 QaP)1/2
CN = 1000/[(10 + 5(1.5) + 10(0.86) — 10(0.862 + 1.25(0.86 x 1.5))1/2
CN = 1000/10.77
CN = 93
2 Unit Peak Discharge (qu) and Runoff Rate (Qp)
(Initial Abstraction)
Ia = 0.151 (per Table 4-1 of TR-55 Manual)
Ia/P = 0.151/1.5 = 0.10 Tc = 8 minutes (0.1.3 brs)
Unit Peak Discharge (qu) = 620 csm/in (per Exhibit 4-III of TR-55 Manual)
3 Peak Runoff Rate
Qp = qu x A x Qa = (620 csrnlin)(1.8I ac)(1 mi2/640 ac)(0.86 in) = 1.51 cfs

Ditch Velocity Calculations
Given: Use Manning's Equation for these calculations. Roughness coefficient, n, is
0.035 for grassed channel flow. Velocity is calculated for maximum flow at shoulder
elevation. Side slopes of the ditch are 3 to 1.
Ditch 1: Calculations are from Top of Bank elevation 17.24 going cast to stormwater
structure no. 1.
Wetted Perimeter, WP = 9.75
Slope, S = (17.0-15.5)/l00 = 0.015
Hydraulic Radius, R = A/WP = 10.43/9.75 = 1.07
V = 1.49/n x R213 x S112= 1.49/0.035 x 1.07213 x 0.015"' = 5.44 fps
