Dear Mr. Denard:
On behalf of the MOD CLT Property, LLC (applicant), Terracon is pleased to submit the below
responses to the North Carolina Department of Environmental Quality (NCDEQ) Division of Water
Resources' (DWR) request for additional information, dated April 27, 2022, pertaining to the NPDES
Permit Application for temporary construction related discharge at the above -referenced site. Please
note that while the NPDES Permit Application received by NCDEQ on January 28, 2022, indicates
that MOD CLT Venture, LLC is the applicant for the permit, the correct applicant to whom the
NPDES permit should be issued is an affiliated entity, MOD CLT Property, LLC. Terracon has
provided the additional information requested below:
1) Receiving Stream Classification
According to NCDEQ DWR's online surface water classifications map, the receiving stream for the
proposed discharge, Little Sugar Creek, is a Class C water. Class C waters are not subject to
discharge restrictions and/or stricter treatment standards such as those that may be required for
certain stream classifications (e.g. ORW, WS, SA, NSW, and HQ).
2) Basinwide Water Quality Plan
According to the most recent Catawba River Basinwide Water Quality Plan (2010), Little Sugar
Creek is listed as impaired for copper, mercury, and turbidity standards as well as biological integrity
of fish and benthic communities (page 3.12 of the Plan). The Basinwide Plan includes total
maximum daily load (TMDL) restrictions (see Item # 3 below for more information regarding TMDLs)
to limit wastewater discharge within the Catawba River Basin. The Basinwide Plan indicates that
Little Sugar Creek is subject to TMDLs for turbidity and fecal coliform bacteria (FCB; page 3.13 of
the Plan). It should be noted that the Basinwide Plan also indicates that during the TMDL study
window (1997 to 2004), Little Sugar Creek turbidity did not exceed the applicable turbidity standard
and that the TMDL in question only covers Long Creek (page 1.43 of the Plan).

3) Impaired Waters and TMDLs
According to a Final Report issued by NCDEQ in 2005 establishing TMDLs for turbidity within the
Catawba River Basin, the TMDL for turbidity is only applicable to the portion of Little Sugar Creek
between North Carolina Highway 51 and the North Carolina -South Carolina state line, which begins
approximately 8 miles south of the site. As such, the proposed discharge to Little Sugar Creek is not
limited by an established TMDL.
According to a Final Report issued by NCDEQ in 2002 establishing TMDLs for FCB in four
watersheds within Mecklenburg County, the entirety of Little Sugar Creek from its source to the state
line is subject to the FCB TMDL. The proposed discharge is not a potential source of FCB, as it
originates as dewatered groundwater generated during installation of deep foundations at a
construction site. As such, the proposed discharge will not result in FCB impact to Little Sugar Creek
or result in exceedance of the established TMDL.
A TMDL was also established for dissolved oxygen (DO) in Little Sugar Creek in 1996. The
proposed discharge is not expected to significantly affect the DO within Little Sugar Creek, as it is
composed of groundwater from dewatered foundation installation activities in an urban area and it is
not expected to be loaded with nutrients such as phosphorus and nitrate that would reduce DO.
Further, the effluent will be treated on -site via carbon filtration prior to discharge. This carbon
filtration will remove volatile organic compounds that could be utilized by microbes within Little Sugar
Creek as a food source, the metabolisms of which would also consume oxygen and lower DO. As
such, the DO TMDL should not limit the proposed discharge.
4) Presence of Endangered Species
According to the USFWS Information for Planning and Consultation (iPAC) online system, the
following listed endangered species are potentially present in the general region of the site and
down -stream portions (within approximately 3 miles of the proposed discharge point) of Little Sugar
Creek: Michaux's Sumac (flowering plant), Schweinitz's Sunflower (flowering plant), Smooth
Coneflower (flowering plant), Northern Long-eared Bat (mammal), Monarch Butterfly (insect), and
Carolina Heelsplitter (clam). In addition, a number of migratory birds are listed in the iPAC
information. As the Carolina Heelsplitter is the only aquatic species potentially present in Little Sugar
Creek, there would be no expected impact to the other species listed above. According to the most
recent Catawba River Basinwide Water Quality Plan (2010), the only stream in the Catawba River
basin that supports populations of the Carolina Heelspliter is Waxhaw Creek (page 3.16 of the Plan),
which enters the Catawba River some 30 miles south of the point of proposed discharge to Little
Sugar Creek. As such, there would be no expected impact to the Carolina Heelsplitter from the
proposed discharge. A summary of the iPAC endangered species information is included an
attachment to this letter.

IPaC resource list
This report is an automatically generated list of species and other resources such as critical
habitat (collectively referred to as trust resources) under the U.S. Fish and Wildlife Service's
(USFWS) jurisdiction that are known or expected to be on or near the project area referenced
below. The list may also include trust resources that occur outside of the project area, but
that could potentially be directly or indirectly affected by activities in the project area.
However, determining the likelihood and extent of effects a project may have on trust
resources typically requires gathering additional site -specific (e.g., vegetation/species
surveys) and project -specific (e.g., magnitude and timing of proposed activities) information.
Below is a summary of the project information you provided and contact information for the
USFWS office(s) with jurisdiction in the defined project area. Please read the introduction to

Endangered species
This resource list is for informational purposes only and does not constitute an analysis
of project level impacts.
The primary information used to generate this list is the known or expected range of each
species. Additional areas of influence (AOI) for species are also considered. An AOI includes
areas outside of the species range if the species could be indirectly affected by activities in
that area (e.g., placing a dam upstream of a fish population even if that fish does not occur at
the dam site, may indirectly impact the species by reducing or eliminating water flow
downstream). Because species can move, and site conditions can change, the species on this
list are not guaranteed to be found on or near the project area. To fully determine any
potential effects to species, additional site -specific and project -specific information is often
required.

The graphs below provide our best understanding of when birds of concern are most likely
to be present in your project area. This information can be used to tailor and schedule your
project activities to avoid or minimize impacts to birds. Please make sure you read and
understand the FAQ "Proper Interpretation and Use of Your Migratory Bird Report" before
using or attempting to interpret this report.
Probability of Presence ( )
Each green bar represents the bird's relative probability of presence in the 10km grid cell(s)
your project overlaps during a particular week of the year. (A year is represented as 12 4-
week months.) A taller bar indicates a higher probability of species presence. The survey
effort (see below) can be used to establish a level of confidence in the presence score. One
can have higher confidence in the presence score if the corresponding survey effort is also
high
How is the probability of presence score calculated? The calculation is done in three steps:
1. The probability of presence for each week is calculated as the number of survey events in
the week where the species was detected divided by the total number of survey events
for that week. For example, if in week 12 there were 20 survey events and the Spotted
Towhee was found in 5 of them, the probability of presence of the Spotted Towhee in
week 12 is 0.25.
2. To properly present the pattern of presence across the year, the relative probability of
presence is calculated. This is the probability of presence divided by the maximum
probability of presence across all weeks. For example, imagine the probability of
presence in week 20 for the Spotted Towhee is 0.05, and that the probability of presence
https://ipac.ecosphere.fws.gov/location/N3SAC6CFV5HK7HJXQCKQFJ4AGU/resources 7/14

4/28/22, 2:19 PM IPaC: Explore Location resources
at week 12 (0.25) is the maximum of any week of the year. The relative probability of
presence on week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2.
3. The relative probability of presence calculated in the previous step undergoes a statistical
conversion so that all possible values fall between 0 and 10, inclusive. This is the
probability of presence score.
To see a bar's probability of presence score, simply hover your mouse cursor over the bar.
Breeding Season ( )
Yellow bars denote a very liberal estimate of the time -frame inside which the bird breeds
across its entire range. If there are no yellow bars shown for a bird, it does not breed in your
project area.
Survey Effort (I)
Vertical black lines superimposed on probability of presence bars indicate the number o
surveys performed for that species in the 10km grid cell(s) your project area overlaps. The%
number of surveys is expressed as a range, for example, 33 to 64 surveys. Ilk lilt
iNiik
To see a bar's survey effort range, simply hover your mouse cursor over the bar.
No Data ( )
A week is marked as having no data if there were no survey events for that week.
Survey Timeframe ilk %MOP
Surveys from only the last 10 years are used in order to ensure delivery of currently relevant
information. The exception to this is areas off the Atlantic coast, where bird returns are
based on all years of available data, since data in these areas is currently much more sparse.

Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all
birds at any location year round. Implementation of these measures is particularly important when birds
are most likely to occur in the project area. When birds may be breeding in the area, identifying the
locations of any active nests and avoiding their destruction is a very helpful impact minimization measure.
To see when birds are most likely to occur and be breeding in your project area, view the Probability of
Presence Summary. Additional measures or permits may be advisable depending on the type of activity
you are conducting and the type of infrastructure or bird species present on your project site.
What does IPaC use to generate the migratory birds potentially occurring in my specified location?
The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC) and other
species that may warrant special attention in your project location.

The migratory bird list generated for your project is derived from data provided by the Avian Knowledge
Network (AKN). The AKN data is based on a growing collection of survey, banding, and citizen science
datasets and is queried and filtered to return a list of those birds reported as occurring in the 10km grid
cell(s) which your project intersects, and that have been identified as warranting special attention because
they are a BCC species in that area, an eagle (Eagle Act requirements may apply), or a species that has a
particular vulnerability to offshore activities or development.
Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area.
It is not representative of all birds that may occur in your project area. To get a list of all birds potentially
present in your project area, please visit the AKN Phenology Tool.
What does IPaC use to generate the probability of presence graphs for the migratory birds potentially
occurring in my specified location?
The probability of presence graphs associated with your migratory bird list are based on data provided by
the Avian Knowledge Network (AKN). This data is derived from a growing collection of survey, banding, and
citizen science datasets . t 4 )
Probability of presence data is continuously being updated as new and better information becomes
available. To learn more about how the probability of presence graphs are produced and how to interpret
them, go the Probability of Presence Summary and then click on the "Tell me about these graphs" link.
How do I know if a bird is breeding, wintering, migrating or present year-round in my project area?
To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering,
migrating or year-round), you may refer to the following resources: The Cornell Lab of Ornithology All
About Birds Bird Guide, or (if you are unsuccessful in locating the bird of interest there), the Cornell Lab of
Ornithology Neotropical Birds guide. If a bird on your migratory bird species list has a breeding season
associated with it, if that bird does occur in your project area, there may be nests present at some point
within the timeframe specified. If "Breeds elsewhere" is indicated, then the bird likely does not breed in
\IPyour project are
What are the levels of concern for migratory birds?
Migratory birds delivered through IPaC fall into the following distinct categories of concern:
1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their
range anywhere within the USA (including Hawaii, the Pacific Islands, Puerto Rico, and the Virgin
Islands);
2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in
the continental USA; and
3. "Non -BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either
because of the Eagle Act requirements (for eagles) or (for non -eagles) potential susceptibilities in
offshore areas from certain types of development or activities (e.g. offshore energy development or
longline fishing).
Although it is important to try to avoid and minimize impacts to all birds, efforts should be made, in
particular, to avoid and minimize impacts to the birds on this list, especially eagles and BCC species of
rangewide concern. For more information on conservation measures you can implement to help avoid and
minimize migratory bird impacts and requirements for eagles, please see the FAQs for these topics.

Details about birds that are potentially affected by offshore projects
For additional details about the relative occurrence and abundance of both individual bird species and
groups of bird species within your project area off the Atlantic Coast, please visit the Northeast Ocean Data
Portal. The Portal also offers data and information about other taxa besides birds that may be helpful to
you in your project review. Alternately, you may download the bird model results files underlying the portal
maps through the NOAA NCCOS Integrative Statistical Modeling and Predictive Mapping of Marine Bird
Distributions and Abundance on the Atlantic Outer Continental Shelf project webpage.
Bird tracking data can also provide additional details about occurrence and habitat use throughout the
year, including migration. Models relying on survey data may not include this information. For additional
information on marine bird tracking data, see the Diving Bird Study and the nanotag studies or contact
Caleb Spiegel or Pam Loring.
What if I have eagles on my list?
*444
If your project has the potential to disturb or kill eagles, you may need to obtain a permit to avoid violating
the Eagle Act should such impacts occur.
Proper Interpretation and Use of Your Migratory Bird Report
The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of
priority concern. To learn more about how your list is generated, and see options for identifying what
other birds may be in your project area, please see the FAQ "What does IPaC use to generate the migratory
birds potentially occurring in my specified location". Please be aware this report provides the "probability
of presence" of birds within the 10 km grid cell(s) that overlap your project; not your exact project
footprint. On the graphs provided, please also look carefully at the survey effort (indicated by the black
vertical bar) and for the existence of the "no data" indicator (a red horizontal bar). A high survey effort is
the key component. If the survey effort is high, then the probability of presence score can be viewed as
more dependable. In contrast, a low survey effort bar or no data bar means a lack of data and, therefore, a
lack of certainty about presence of the species. This list is not perfect; it is simply a starting point for
identifying what birds of concern have the potential to be in your project area, when they might be there,
and if they might be breeding (which means nests might be present). The list helps you know what to look
for to confirm presence, and helps guide you in knowing when to implement conservation measures to
avoid or minimize potential impacts from your project activities, should presence be confirmed. To learn
more about conservation measures, visit the FAQ "Tell me about conservation measures I can implement
to avoid or minimize impacts to migratory birds" at the bottom of your migratory bird trust resources
page.

Wetlands in the National Wetlands Inventory
i
Impacts to NWI wetlands and other aquatic habitats may be subject to regulation under
Section 404 of the Clean Water Act, or other State/Federal statutes.
For more information please contact the Regulatory Program of the local U.S. Army Corps of
Engineers District.

Data limitations
The Service's objective of mapping wetlands and deepwater habitats is to produce reconnaissance level
information on the location, type and size of these resources. The maps are prepared from the analysis of
high altitude imagery. Wetlands are identified based on vegetation, visible hydrology and geography. A
margin of error is inherent in the use of imagery; thus, detailed on -the -ground inspection of any particular
site may result in revision of the wetland boundaries or classification established through image analysis.
The accuracy of image interpretation depends on the quality of the imagery, the experience of the image
analysts, the amount and quality of the collateral data and the amount of ground truth verification work
conducted. Metadata should be consulted to determine the date of the source imagery used and any
mapping problems.
Wetlands or other mapped features may have changed since the date of the imagery or field work. There
may be occasional differences in polygon boundaries or classifications between the information depicted
on the map and the actual conditions on site.

Certain wetland habitats are excluded from the National mapping program because of the limitations of
aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or
submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and
nearshore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also
been excluded from the inventory. These habitats, because of their depth, go undetected by aerial
imagery.
Data precautions
Federal, state, and local regulatory agencies with jurisdiction over wetlands may define and describe
wetlands in a different manner than that used in this inventory. There is no attempt, in either the design or
products of this inventory, to define the limits of proprietary jurisdiction of any Federal, state, or local
government or to establish the geographical scope of the regulatory programs of government agencies.
Persons intending to engage in activities involving modifications within or adjacent to wetland areas should
seek the advice of appropriate federal, state, or local agencies concerning specified agency regulatory
programs and proprietary jurisdictions that may affect such activities.
