Please see your email below and attachments for responses.
The 401 review has also being initiated (the payment got held up) so I am copying Sue on this additional/supplemental
information.
If either of you need anything else please let me know.
Thanks

Subject: SAW-2019-01969 / Austin Quarter Landfill Expansion / Swepsonville / Alamance County, NC - NWP 39 REQUEST
FOR ADDITIONAL INFORMATION
Phil:
Thanks for your time on the phone last week. Per our discussion, the Pre -construction Notification (PCN) for the
proposed Austin Quarter Landfill Expansion (SAW-2019-01969), dated July 28, 2021 is incomplete.
To facilitate our documentation of the proposed project's compliance with requirements and conditions for use of
Nationwide Permit 39, please provide the following information:
1- Skimmer basins 2 (Future Cell 2) and 1 (Future Cell 3), shown on Exhibit X1, both appear to include potential
features beyond what was investigated during the site visit. In both circumstances, stream features (drainages?)
1

are drawn through the basins. Skimmer basin 1 also appears to be proposed outside areas included in the PJD
request. Would impacts to potentially jurisdictional features be required in these areas?
The skimmer basins have been moved and the plans updated (see attached). No work on Cells 2 and 3 is
anticipated before further delineation and permitting are performed. The JD and the current PCN are limited to
Cell 1. There are potential features that require evaluation in the future cells and we understand that these will
require additional work and cumulatively count toward thresholds. Cell 1 can operate independently as an
expansion and is not dependent on Cells 2 or 3 to fully function as a disposal facility. The approximate extent of
the PJD included all areas up to but not including the stream shown east of Sediment Basin 1. The area between
the PJD limits and the stream has been field inspected and is upland.
2- Would any impacts be required associated with leachate collection and transfer to on -site storage tanks?
Leachate collection would be within the proposed limit of fill and not require additional impacts.
3- Engineering exhibits will become part of the verification issued for this project. To avoid confusion for the
permittee and their contractor(s), please provide exhibits to show only where the current project is proposed.
Please see the attached exhibits revised to only include the current cell (1).
4- Exhibit X1, Engineering Plan — Phase 6 Erosion Control Plan — Stage 1, appears to show Skimmer basin 4 within
Wetland WI. The application states that sediment basins have been designed outside jurisdictional areas, but it
isn't clear without those areas depicted on engineering exhibits. Please add jurisdictional areas to engineering
exhibits. Please also include a north arrow and graphic scale on exhibits.
Please see the attached exhibits.
5- The proposal to provide 1:1 mitigation for non -forested wetland impacts requires a completed NCWAM form.
Please complete and submit that form for our review and use.
Please see the attached NCWAM form.
Additionally, A NWP 26 (SAW-1998-20079) was previously issued to verify the loss of 25 linear feet (50 square feet) of
stream realignment and 0.079 acre of wetland. We understand it isn't possible to determine whether a standard permit
would be required 20-years in the future, but please note that these impacts would be considered cumulative with any
future request.
Please provide the requested information within 30 days, or your application will be withdrawn. Feel free to contact me
with any questions or concerns.

Evidence of stressors affecting the assessment area (may not be within the assessment area)
Please circle and/or make note on the last page if evidence of stressors is apparent. Consider departure from reference, if appropriate, in
recent past (for instance, within 10 years). Noteworthy stressors include, but are not limited to the following.
• Hydrological modifications (examples: ditches, dams, beaver dams, dikes, berms, ponds, etc.)
• Surface and sub -surface discharges into the wetland (examples: discharges containing obvious pollutants, presence of nearby septic
tanks, underground storage tanks (USTs), hog lagoons, etc.)
• Signs of vegetation stress (examples: vegetation mortality, insect damage, disease, storm damage, salt intrusion, etc.)
• Habitat/plant community alteration (examples: mowing, clear -cutting, exotics, etc.)

diversity [if appropriate], hydrologic alteration)
Surface and Sub -Surface Storage Capacity and Duration — assessment area condition metric
Check a box in each column. Consider surface storage capacity and duration (Surf) and sub -surface storage capacity and duration (Sub).
Consider both increase and decrease in hydrology. A ditch <_ 1 foot deep is considered to affect surface water only, while a ditch > 1 foot
deep is expected to affect both surface and sub -surface water. Consider tidal flooding regime, if applicable.
Surf Sub
❑A ❑A Water storage capacity and duration are not altered.
❑B ®B Water storage capacity or duration are altered, but not substantially (typically, not sufficient to change vegetation).
®C ❑C Water storage capacity or duration are substantially altered (typically, alteration sufficient to result in vegetation change)
(examples: draining, flooding, soil compaction, filling, excessive sedimentation, underground utility lines).
Water Storage/Surface Relief — assessment area/wetland type condition metric (skip for all marshes)

®A ®A Little or no evidence of pollutants or discharges entering the assessment area
❑B ❑B Noticeable evidence of pollutants or discharges entering the wetland and stressing, but not overwhelming the
treatment capacity of the assessment area
❑C ❑C Noticeable evidence of pollutants or discharges (pathogen, particulate, or soluble) entering the assessment area and
potentially overwhelming the treatment capacity of the wetland (water discoloration, dead vegetation, excessive
sedimentation, odor)
6. Land Use — opportunity metric (skip for non -riparian wetlands)
Check all that apply (at least one box in each column). Evaluation involves a GIS effort with field adjustment. Consider sources draining
to assessment area within entire upstream watershed (WS), within 5 miles and within the watershed draining to the assessment area (5M),
and within 2 miles and within the watershed draining to the assessment area (2M).
WS 5M 2M
❑A ❑A ❑A > 10% impervious surfaces

12. Wetland Intactness — wetland type condition metric (evaluate for Pocosins only)
❑A Pocosin is the full extent (>_ 90%) of its natural landscape size.
❑B Pocosin type is < 90% of the full extent of its natural landscape size.
13. Connectivity to Other Natural Areas — landscape condition metric
13a. Check appropriate box(es) (a box may be checked in each column). Involves a GIS effort with field adjustment. This metric
evaluates whether the wetland is well connected (Well) and/or loosely connected (Loosely) to the landscape patch, the contiguous
naturally vegetated area and open water (if appropriate). Boundaries are formed by four -lane roads, regularly maintained utility line
corridors the width of a four -lane road or wider, urban landscapes, maintained fields (pasture and agriculture), or open water > 300
feet wide.

❑Yes ❑No Wetland type has a surface hydrology connection to open waters/stream or tidal wetlands.
14. Edge Effect — wetland type condition metric (skip for all marshes and Estuarine Woody Wetland)
May involve a GIS effort with field adjustment. Estimate distance from wetland type boundary to artificial edges. Artificial edges include
non -forested areas >_ 40 feet wide such as fields, development, roads, regularly maintained utility line corridors, and clear -cuts. Consider
the eight main points of the compass. Artificial edge occurs within 150 feet in how many directions? If the assessment area is clear cut,
select option "C."
❑A 0
❑ B 1 to 4
®C 5to8
15. Vegetative Composition — assessment area condition metric (skip for all marshes and Pine Flat)
❑A Vegetation is close to reference condition in species present and their proportions. Lower strata composed of appropriate
species, with exotic plants absent or sparse within the assessment area.
❑B Vegetation is different from reference condition in species diversity or proportions, but still largely composed of native species
characteristic of the wetland type. This may include communities of weedy native species that develop after clearcutting or clearing.
It also includes communities with exotics present, but not dominant, over a large portion of the expected strata.
®C Vegetation severely altered from reference in composition, or expected species are unnaturally absent (planted stands of non -
characteristic species or at least one stratum inappropriately composed of a single species), or exotic species are dominant in at
least one stratum.
16. Vegetative Diversity — assessment area condition metric (evaluate for Non -tidal Freshwater Marsh only)
❑A Vegetation diversity is high and is composed primarily of native species (< 10% cover of exotics).
❑B Vegetation diversity is low or has > 10% to 50% cover of exotics.
❑C Vegetation is dominated by exotic species (> 50 % cover of exotics).

17. Vegetative Structure — assessment area/wetland type condition metric
17a. Is vegetation present?
®Yes ❑No If Yes, continue to 17b. If No, skip to Metric 18.
17b. Evaluate percent coverage of assessment area vegetation for all marshes only. Skip to 17c for non -marsh wetlands.
❑A >_ 25% coverage of vegetation
❑B < 25% coverage of vegetation
17c. Check a box in each column for each stratum. Evaluate this portion of the metric for non -marsh wetlands. Consider
structure in airspace above the assessment area (AA) and the wetland type (WT) separately.

®B Not A
19. Diameter Class Distribution — wetland type condition metric (skip for all marshes)
❑A Majority of canopy trees have stems > 6 inches in diameter at breast height (DBH); many large trees (> 12 inches DBH) are
present.
❑B Majority of canopy trees have stems between 6 and 12 inches DBH, few are > 12 inch DBH.
®C Majority of canopy trees are < 6 inches DBH or no trees.
20. Large Woody Debris — wetland type condition metric (skip for all marshes)
Include both natural debris and man -placed natural debris.
❑A Large logs (more than one) are visible (> 12 inches in diameter, or large relative to species present and landscape stability).
®B Not
21. Vegetation/Open Water Dispersion — wetland type/open water condition metric (evaluate for Non -Tidal Freshwater Marsh only)

22. Hydrologic Connectivity — assessment area condition metric (evaluate for riparian wetlands and Salt/Brackish Marsh only)
Examples of activities that may severely alter hydrologic connectivity include intensive ditching, fill, sedimentation, channelization, diversion,
man-made berms, beaver dams, and stream incision. Documentation required if evaluated as B, C, or D.
❑A Overbank and overland flow are not severely altered in the assessment area.
❑B Overbank flow is severely altered in the assessment area.
®C Overland flow is severely altered in the assessment area.
❑D Both overbank and overland flow are severely altered in the assessment area.
Notes
22. Approximately 1/3 of the original watershed for the impact area is current landfill, which reroutes stormwater drainage. See attached existing
conditions.
