1.0 Introduction
Per Conditions 9 and 13 of the modified 401 Water Quality Certification issued in January 2009 for the
PCS Phosphate mine continuation near Aurora NC (DWQ #2008-0868, version 2.0), wetland hydrology of
the portions of the Bonnerton Road non-riverine wet hardwood forest (NRWHF) shown as “135A” and
“58A” on Figure 1 shall be monitored before and after the mine moves through the area between the
avoided NRWHF areas and within the permitted mine boundary (Figure 2). The data collected are to
ensure that the wetland hydrology of the two NRWHF areas avoided by the permitted mine boundary is
maintained after mine impacts are completed and/or the mined-through area has been reclaimed.
1.1 Area Description
The Bonnerton Road NRWHF is located on a peninsula between Durham Creek to the west and Porter
Creek to the east; both creeks flow north to the nearby Pamlico River (Figure 1). Surface water flow of
the peninsula into the two creeks is separated by the divide known as the Suffolk Scarp, a geomorphic
feature whose highest elevation in this vicinity is just to the west of the 135A NRWHF (Figure 1). Slope of
the terrain on the most eastern side of the scarp towards Porter Creek is ~0.2 percent, while the slope
approaches 1 percent nearer to the eastern toe of the Suffolk Scarp. Similar to other outer coastal plain
interfluves in North Carolina, where the underlying Castle Hayne limestone is close to the surface, the
forested landscape of the peninsula is gently rolling with occasional small closed depressions and small
non-hydric areas of higher elevation.
2.0 Methodology
2.1 Water Level
To monitor the pre-mine hydrology of the monitored area, a total of 14 semi-continuous electronic Level
TROLL 500 data-logger water level monitoring wells, manufactured by In-Situ, were installed in June and
July 2015 at the locations shown in Figure 3 (BHW1-BHW14). In addition to the 14 wells installed in 2015,
there are six additional wells used to monitor the wetland hydrology adjacent to upper Porter Creek for a
separate project (locations shown on Figure 3). Two other types of monitoring wells have been used at
four of these locations (PCW1, PCW3, PCW4, and PCW6) since 2006 [Remote Data Systems (RDS) WL20s
and WL80s and RDS Ecotone 20s and Ecotone 80s] but Level TROLL 500s have been in place at all six
locations since 2015 (wells at PCW2 and PCW5 were added).
Each of the 14 Level TROLLs is housed inside a 2-inch diameter PVC well screen (0.010-inch slots) installed
to a depth of approximately 32 inches and backfilled with filter sand. The recorder is suspended on a
43.75-inch cable in the well screen to record water levels within at least ~20 inches below the ground
surface and up to ~20 inches above the surface. Among the 14 wells, the range of water levels which can
be recorded below the surface ranges from -24.25 to -31.75 inches and the range of surface water which
can be recorded ranges from +18.0 to +26.0 inches. The units record the water level every 1.5 hours (16
times per day). The six upper Porter Creek wells are housed inside a 3-inch diameter PVC well screen with
0.010-inch slots, but the Level TROLL cable is 60.25 inches long and among these wells, the range for
below ground water level is -29.75 to -33.25 inches, and the range of surface water is +32.75 to +36.5
6

inches. (The longer cable is used for the upper Porter Creek wells as part of a different monitoring project
methodology and protocol). To prevent damage by bears, the above-ground portions of all well screens
were surrounded by a fence enclosure made of metal T-posts and strands of barbed wire. All 20
monitoring wells were checked and downloaded once a month. Most of the 14 wells are located in
portions of the hardwood flat at slightly higher elevations than the six Porter Creek wells; however, no
elevations have been surveyed so perceived differences in elevation are not quantified. Four monitored
Bonnerton wells (BHW5, BHW6, BHW7, and BHW8) are within the permitted mine boundary; however,
BHW8 was removed for mine related activity in September 2021.
Wetland hydroperiods were calculated for each monitoring well during the growing season. A
hydroperiod is defined as consecutive days during the growing season that the water table is within 12
inches of the surface or the surface is inundated, and is expressed as a percentage of the growing season.
For this project, the growing season is defined by the Regional Supplement to the Corps of Engineers
Wetland Delineation Manual: Atlantic and Gulf Coastal Plain Region (Version 2.0) (USACE ERDC 2010) to
match the Natural Resources Conservation Services’ (NRCS) WETs tables and is 282 days long in non-leap
years (28 February–6 December). For the purposes of this report, a hydroperiod for 6 percent or more of
the growing season is considered a wetland hydroperiod.
2.2 Rainfall and Drought
Rainfall was collected and measured using a RDS tipping bucket style rain gauge until 2019 when it became
obsolete; it was replaced with a Texas Electronic TR-525USW style bucket with similar function and
accuracy (+/- 1% at 0-2 inches/hour). Rainfall lands in the funnel of the rain gauge and is directed down
to the bottom of the funnel where it drips into two calibrated “buckets” balanced on a pivot. Once the
bucket has reached its calibrated amount, 0.010 inch of rain, it tips down registering the event as the
opposite bucket rises to begin collecting the next calibrated amount of rain. Water is allowed to drain out
of a hole on either side of the rain gauge underneath each bucket. The Porter Creek rain gauge was used
for local rainfall data (Figure 3) except during any data gap or malfunction, when gaps were replaced with
data from the nearby DCUT19 (3.3 miles to the northwest) or Aurora (PCS) plant site (4.7 miles to the
east).
Rainfall data collected at the NOAA stations PCS Aurora 6N and Gaylord Bay (starting in August of 2021)
were used by the Natural Resources Conservation Service (NRCS) to provide long term rainfall. These data
were downloaded by CZR Incorporated (CZR) and used to build annual rainfall figures to determine
periods of normal rainfall. ”Range of Normal" refers to the 30th and 70th percentile thresholds of the
probability of onsite rainfall amounts outside of the normal range (based on historical averages). For
2022, the long-term historical averages were updated to include 1992-2021.
Drought conditions are monitored nationally by several indexes. Periods of drought can affect the
hydrology of a site and should be taken into consideration when wetland hydrology is interpreted. As
suggested in the USACE 2010 Regional Supplement, the Palmer Drought Severity Index (PDSI) was used to
determine drought periods for the area. The PDSI is useful because it “takes into account not only
precipitation but also temperature, which affects evapotranspiration, and soil moisture conditions” (US
Army Corps of Engineers 2010). The PDSI is calculated monthly and is based on major climatic divisions
7

within each state (US Army Corps of Engineers 2010). Although the index is not site-specific, for the
purposes of this report it provided sufficient information to make general statements about drought
conditions in the area. Drought conditions described by this index by month and year are for the NOAA
Central Coastal Plain region of North Carolina. The US Drought Monitor website
(http://droughtmonitor.unl.edu) provides a synthesis of multiple indices and impacts and reflects the
consensus of federal and academic scientists on regional conditions on a weekly basis (updated each
Thursday). The area used for regional drought conditions includes numerous watersheds of various sizes
and may cover portions of more than one county.
2.3 PCS Deep Well Pump Operations and Water Levels in CZR Level TROLLs
In previous reports, a dynamic multiple linear regression model was used to compare water depth to
rainfall, wind speed, wind direction, and discharge across three different time periods: pre, during, and
post deep well pump operation. No adverse trends on hydroperiods were detected or attributed to the
deep well pump operation during past evaluations; however, the same test was not repeated for this
report because the influence of estuarine wind-driven water and/or discharge from the Pamlico River is
not expected at the Bonnerton wells since they are well above riparian areas. When discharge and wind
parameters were removed from the evaluation, the remaining data sets (water level and rainfall) both
violated the statistical assumption of normality (were not normally distributed) despite attempts to
normalize. In addition, the statistical power of the non-parametric tests was very low, which is likely
because there were many positive and negative water level readings, as well as many absent water level
readings (greater than approximately 30 inches below the surface, which is the lower range of well
detection). Hydrology graphs of the Bonnerton wells are depicted along with each deep well pump
operation’s on/off dates to depict the relationship between deep well pump operations and Bonnerton
well hydrology (Figure 12).
3.0 Results and Discussion
3.1 Soil Series and Soil Profiles
The soil survey for Beaufort County NC (Kirby 1995) and web soil survey data show the area of the
Bonnerton NRHWF as underlain mostly by Tomotley fine sandy loam and several other soil series which
are all considered hydric; two of the soil series are considered non-hydric (Altavista fine sandy loam and
Augusta fine sandy loam) (Figure 4). Since earlier well installation soil profiles were described by several
biologists at different times, in 2016/2017, soil profiles at all 20 well locations were re-described using the
NRCS hydric soil indicators (USDA 2010) as directed by the 2010 regional supplement (soil profiles included
in Appendix A).
3.2 Rainfall and Drought in 2015 - 2022
Monthly rainfall totals recorded in 2015-2022 at the Porter Creek rain gauge and at the PCS Aurora 6N
station are shown in Table 1.
In 2022, monthly rainfall totals below the 30th percentile occurred in February, August, October, and
November; within 30-70th percentiles in April, May, June, July, September, and December; and above the
8

70th percentile in January and March (Figure 5). Annual 2022 rainfall total at the Porter Creek rain gauge
was 42.31 inches. Porter rain gauge monthly totals were highest for the year in January and lowest in the
month of October. Days of above normal rainfall (1 January through 14 February, 24 March through 22
April, and 3 June through 20 June) were excluded from hydroperiod calculations to compare with
hydroperiods using all rainfall data.
In 2021, monthly rainfall totals below the 30th percentile occurred in May, September, November, and
December; within 30-70th percentiles in March, April, July, and October; and above the 70th percentile in
January, February, June, and August (Figure 5). Annual 2021 rainfall total at the Porter Creek rain gauge
was 51.04 inches. Porter rain gauge monthly totals were highest for the year in June which was the same
month that the PCS Aurora 6N rain gauge recorded its highest monthly total. Days of above normal rainfall
(13 February through 21 March, 7 June through 10 July, and 3 August through 31 August) were excluded
from hydroperiod calculations to compare with hydroperiods using all rainfall data.
In 2020, monthly rainfall totals below the 30th percentile occurred in January; within 30-70th percentiles
in February, April, June, September, and October; and above the 70th percentile in March, May, July,
August, November, and December (Figure 5). Annual 2020 rainfall total at the Porter Creek rain gauge
was 73.21 inches. Porter rain gauge monthly totals were highest for the year in November while the PCS
Aurora 6N rain gauge recorded its highest monthly total in August. Days of above normal rainfall (6
February through 9 March, 21 May through 27 June, 28 July through 28 August, and 12 November through
12 December) were excluded from hydroperiod calculations to compare with hydroperiods using all
rainfall data.
In 2019, monthly rainfall totals for January, February, April, June, July, and November through December
were below the WETS 70th percentile (Figure 5); annual rainfall total at the Porter Creek rain gauge was
56.67 inches. Porter rain gauge monthly totals were highest for the year in August associated with heavy
downpours while the PCS Aurora 6N rain gauge recorded its highest monthly total mostly due to Tropical
Storm Dorian on September 6th. Days of above normal rainfall (13 April through 9 May, 12 July through
20 July, 24 July through 11 August, and 28 August through 27 September) were excluded from
hydroperiod calculations to compare with hydroperiods using all rainfall data.
In 2018, monthly rainfall totals for January, February, and March were below the WETS 70th percentile
(Figure 6); the majority of the year was above the WETS normal range and annual rainfall total at the
Porter Creek gauge was 67.61 inches. The wettest tropical cyclone on record in the Carolinas, Hurricane
Florence (slow moving Category 1 storm), made landfall in Wrightsville Beach, NC on 14 September.
Rainfall throughout Beaufort County was generally 4 to 8 inches with a storm rainfall total of 6.95 inches
in Belhaven. The heaviest rainfall totals fell across the extreme southern part of the county which caused
flash flooding in some locations.
In 2017, monthly rainfall totals for January, February, October, and November were below the WETS 30th
percentile (Figure 7); annual rainfall total at the Porter Creek gauge was 48.09 inches. April was the only
month with total rainfall above the WETS normal range. A strong coastal low pressure system produced
9

heavy rainfall and flash flooding from 23 April to 25 April. Based on the 30-day rolling total, rainfall from
24 April through 24 May was considered above normal.
In 2016, monthly rainfall was greater in February, June, July, September and October when compared to
the WETS percentiles (Figure 8); annual total rainfall at the Porter Creek gauge was 55.93 inches. Rainfall
for March and mid to late August were below normal with the remainder of the year within WETS normal
range. Hurricane Matthew, a Category 1 storm, made landfall in Cape Romain National Wildlife Refuge,
SC on 8 October 2016. Above average rainfall spikes began in the PCS area on 7 October, coincident with
arrival of the outer rain bands of the hurricane in North Carolina. There were several periods of above
normal rainfall that were excluded when hydroperiods were calculated for normal and below normal
rainfall: 3 February through 5 March, 3 June through 5 July, 7-30 July, 11-30 September, and 7 October
through 7 November.
In 2015, monthly rainfall was greater in June, October, and late November through late December when
compared to the WETS percentiles (Figure 9); annual total rainfall at the Porter Creek gauge was 58.96
inches. At the end of January and March, the 30-day rolling total was slightly above normal. Rainfall for
the month of August was below normal and the rainfall for the remainder of the year fell within the WETS
normal range. Periods of above normal rainfall included 3 June through 3 July, 2 October through 1
November, and 20 November through 20 December.
For 2022, the US Drought Monitor (http://droughtmonitor.unl.edu) indicated 18 weeks were considered
abnormally dry (DO), 10 weeks were considered moderately dry (D1), and the remaining weeks had no
drought status in the vicinity of the Bonnerton Road NRHWF “135A” and “58A” project areas (Table 2).
This is the highest record for number of weeks with a drought status since monitoring began in 2015. In
2021, eight weeks were considered abnormally dry (DO), 8 weeks were considered moderately dry (D1),
and four weeks were considered severe drought (D2). In 2020, three weeks were considered abnormally
dry (DO). In 2019, nine weeks were considered abnormally dry (DO). In 2018, one week was considered
abnormally dry (DO). In 2017, five weeks were considered abnormally dry (D0). During 2016, three weeks
in April were assigned drought condition (D0 – Abnormally Dry). In 2015, all 41 weeks of the growing
season were considered normal with no drought status.
3.3 Wetland Hydrology by Year
2022
Nineteen wells were monitored in 2022, 13 BHW wells and six PCW wells (BHW8 was removed in 2021
due to permitted mine activities). All 13 BHW and three of six PCW well locations recorded wetland
hydroperiods in 2022 during all rainfall conditions. Of the wells that recorded a wetland hydroperiod in
2022, six BHW wells had hydroperiods for ≥6.0-12.5 percent, seven BHW wells had hydroperiods for
>12.5-25.0 percent and three PCW wells had hydroperiods for >12.5-25.0 percent of the growing season
during all rainfall conditions (Table 3b). From 2021 to 2022, six BHW wells decreased in hydrologic zones
from the >12.5-25.0 percent of the growing season zone and three PCW wells decreased in hydrologic
zones from the ≥6.0-12.5 percent of the growing season zone.
10

When hydroperiods that occurred during above normal rainfall were removed (Figure 5), no BHW or PCW
well locations exhibited any wetland hydroperiods (Table 3a). This represents a decrease in hydrologic
zone from 2021 to 2022 for all 19 of the wells.
2021
All BHW and PCW well locations recorded wetland hydroperiods in 2021, even when periods of above
normal were excluded (Tables B-1a and 1b, Appendix B). Of the 14 BHW wells, all wells had hydroperiods
for >12.5-25.0 percent of the growing season during all rainfall conditions. Similarly, all six PCW wells had
hydroperiods for >12.5-25.0 percent. From 2020 to 2021, four BHW wells decreased in hydrologic zones
from the 25.0 to 75.0 percent of the growing season zone. Data for BHW8 are not available after 21
September 2021 due to permitted mine activities.
When hydroperiods that occurred during above normal rainfall were removed (Figure 6), 18 wells
recorded hydroperiods in the >6.0-12.5 percent of the growing season zone and 2 wells recorded
hydroperiods in the >12.5-25.0 percent of the growing season zone. This represents a decrease in
hydrologic zone from 2020 to 2021 for 19 of the wells.
2020
For 2020, 18 wells recorded wetland hydroperiods for 12.5 to 25.0 percent of the growing season and two
wells increased in hydrologic zones to record wetland hydroperiods for 25.0 to 75.0 percent of the growing
season when periods of above normal rainfall were excluded (Figure 7). During all rainfall conditions four
wells had hydroperiods for >25.0-75.0 percent of the growing season while all the other wells remained
in the >12.5-25.0 percent range (Tables B-1b, Appendix B). Under all rainfall conditions, two wells changed
from the >12.5-25.0 percent hydrologic zone to the >25.0-75.0 percent from 2019 to 2020.
2019
For 2019, all locations recorded wetland hydroperiods for 12.5 to 25.0 percent of the growing season
when periods of above normal rainfall were excluded (Figure 8). During all rainfall conditions two wells
had hydroperiods for >25.0-75.0 percent of the growing season while all the other wells remained in the
>12.5-25.0 percent range (Tables B-1b, Appendix B). Under all rainfall conditions, four wells changed from
the >25.0-75.0 percent hydrologic zone to the >12.5-25.0 percent from 2018 to 2019.
2018
All BHW and PCW wells recorded wetland hydroperiods in 2018, even when periods of above normal were
excluded (Tables 3a and 3b). Of the 14 BHW wells, eight wells had hydroperiods for >12.5-25.0 percent
and six wells had hydroperiods for >25-75 percent of the growing season during all rainfall conditions.
Similarly, all six PCW wells had hydroperiods for >12.5-25.0 percent.
When hydroperiods that occurred during above normal rainfall were removed (Figure 9), six wells
decreased from >25.0-75.0 percent to >12.5-25.0 percent of the growing season; all other wells
maintained hydroperiods for >12.5-25.0 percent of the growing season.
11

2017
All well locations recorded wetland hydroperiods, even when periods of above normal were excluded
(Tables B-1a and 1b, Appendix B). Of the 14 BHW wells, eight wells had hydroperiods for >12.5-25.0
percent and six wells had hydroperiods for >25-75 percent of the growing season during all rainfall
conditions. Similarly, all six PCW wells had hydroperiods for >12.5-25.0 percent.
When hydroperiods that occurred during above normal rainfall were removed (Figure 10), six wells
decreased from >25.0-75.0 percent to >12.5-25.0 percent of the growing season; all other wells
maintained hydroperiods for >12.5-25.0 percent of the growing season.
2016
The first full monitoring year for the 14 BHW wells was 2016. All well locations recorded wetland
hydroperiods during the 2016 growing season (Tables B-1a and 1b, Appendix B). Of the 14 BHW wells,
hydroperiods for eight wells were >12.5-25.0 percent and six wells were >25.0-75.0 percent of the growing
season. Similarly, all six PCW wells had hydroperiods for >12.5-25.0 percent.
When above normal rainfall was removed (Figure 11), only one well (PCW1) decreased from >12.5-25.0
percent to ≥6.0-12.5 percent of the growing season during normal and below normal rainfall conditions.
2015
The 14 Bonnerton wells (BHW) were installed at the end of June 2015 and beginning of July 2015; the six
upper Porter Creek (PCW) wells collected data all year. All 14 BHW wells exhibited wetland hydroperiods
using all rainfall data between June and December and the six Porter Creek wells exhibited wetland
hydroperiods between February and December (Tables B-1b, Appendix B). Among the 14 wells in the
higher elevations of the hardwood flat, BHW6 had the longest hydroperiod of 23.8 percent of the growing
season while longest hydroperiods at the remaining wells were in the range of ≥6.0 - 12.5 percent of the
growing season. The six wells in upper Porter Creek are located in somewhat lower elevations than some
of the other 14 wells and using all 2015 rainfall data, longest hydroperiods were >12.5-25.0 percent of the
growing season with PCW6 exhibiting the longest hydroperiod of 24.5 percent (Tables B-1a, Appendix B).
When dates with above normal rainfall during 2015 (Figure 12) were removed and only normal and below
normal rainfall periods are used for evaluation, three BHW wells did not exhibit any wetland hydroperiods
between June and December (one of these four exhibited water within 12 inches of the surface but for
less than 6 percent of the growing season), nine had longest hydroperiods in the range of ≥6.0- 12.5
percent, and longest hydroperiod at one well was >12.5–25.0 percent (Tables B-1a and 1b, Appendix B).
All six PCW wells had wetland hydroperiods in the range of >12.5–25.0 percent of the growing season
during normal and below normal rainfall.

3.4 Mine Perimeter Deep Well Pump Operation and Near Surface Hydrology
At agency request, PCS provided CZR information about the locations (Figure 12) and dates of operation
(Table 5) of pumps in deep wells around the Bonnerton Mod Alt L mine perimeter for analysis of potential
effects on adjacent wetland hydrology attributed to the pump activity. Deep wells within an approximate
half mile of the Bonnerton shallow wells and the months of pump activity in 2022 include: deep wells east
of Bonnerton 1108 (off), 1109 (off), 1110 (off), 1111 (off); deep wells northwestern of Bonnerton 1125
(off), 1124 (off); and deep wells southwest of Bonnerton 1126 (Jan-Feb), 1127 (Jan-May and Sept-Oct),
1128 (Jan-Oct) (Table 5). As in previous years, deep well pump activity does not appear to affect water
levels or hydroperiods at the wetland shallow monitoring wells (Figure 13). Water levels at Bonnerton
respond to rainfall events and seasonal patterns (winter wet and lower levels after spring leaf-out and
during the summer) much like those in other wetlands throughout the area.
4.0 Summary
During 2015-2021 monitoring years, all 20 ground water monitoring wells exhibited wetland hydroperiods
when all rainfall data are used to tabulate consecutive number of days of water levels above -12.0 inches
(relative to ground surface) as shown in Table 4b. In 2022, 16 of the 19 ground water monitoring wells
(BHW8 was removed in 2021 due to permitted mine activities) exhibited wetland hydroperiods when all
rainfall data are used to tabulate consecutive number of days of water levels above -12.0 inches (relative
to ground surface) as shown in Table 4b.
The original 14 Bonnerton wells were installed in June 2015; after the period when longest hydroperiods
are typically recorded. For years 2016-2021, all BHW and PCW wells exhibited wetland hydroperiods
(greater than 12 percent), even when periods of above normal rainfall were excluded (Table 4a). In 2022,
all BHW wells and all but three PCW wells (PCW1, PCW2, and PCW3) exhibited a wetland hydroperiod
(Table 4b), however, only one well (BHW6) exhibited a wetland hydroperiod (8.5 percent) when periods
of above normal rainfall were excluded (Table 4a).
During the course of monitoring, relatively similar wetland hydroperiods have persisted in the Bonnerton
