Dear Ms. Hill,
Enclosed is a copy of the 2007 mitigation monitoring report for the 7-acre created
wetland at Nucor Steel in Hertford County, NC. This report should address the
comments made in your letter dated May 2, 2007.
a) Both hydrology and vegetation survival meet the success criteria for the 2007
growing season.
b) Only four species of trees were planted per the remedial action plan. This
plan was approved by Mr. John Dorney of the NC Division of Water Quality
in a letter (attached) dated December 1, 2004.
c) As requested, we have attached (Appendix B) tables indicating planted and
volunteer species.
Based on the information contained in the enclosed report, CEC believes the mitigation
site is currently meeting all of the success criteria. Please do not hesitate to contact me or
Clement Riddle at [phone].
Sincerely,
Chris Grose

DWQ #19990231
Dear Mr. Riddle:
The Division of Water Quality (DWQ) 401 Oversight and Express Review Permitting Unit has reviewed
the Monitoring Report for the above-referenced site. Our comments on the report are as follows:
a) Remediation efforts to correct problems with hydrology and vegetation survival have been
completed and appeared to be successful, as built, at the end of the 2006 growing season.
b) There is some concern about future vegetative diversity at the site since only four tree species
were planted and Acer rubrum volunteers are already moving in.
c) In future reports, include results for each vegetation sampling point for all monitoring years.
Please provide separate tables for planted and volunteer species. This will help with evaluating
distribution of vegetative success and plant community development.
We look forward to future reports detailing development of the mitigation site over the next several
years. Please feel free to contact Tammy Hill at [phone] or [e-mail] if you
have questions regarding this project or our comments.

Dear Mr. Hairston:
Re: Wetland Mitigation Report

Hertford County
DWQ staff have reviewed your letter of October 29, 2004 (received November 1, 2004)
regarding issues at the wetland creation site at your plant '\In addition, we have reviewed the
Annual Mitigation Report for 2004. Both the report and leytter are clearly written and well
organized and therefore. easy to understand. Please understa*ld that this is not the situation with
many of the mitigation reports submitted to DWQ therefore, `staff sincerely appreciated the effort
done to make this report accurate and user-friendly.
We prefer your option 1 as a remedial action to ensure vegetation success at the site (i.e. replant
with cypress, black gum and ash). However option 2 would also be acceptable to DWQ since it
ultimately aims to meet the success criteria for this site. Since the US Army Corps of Engineers
has the ultimate decision in this matter, we will defer to their final decision regarding option 1 or
option 2.
I can be reached at 919-733-9646 if you have any question.

EXECUTIVE SUMMARY
Nucor Steel (Nucor) was issued a Department of the Army Permit (No. 199811324), a N.C. Division of
Water Quality 401 Certification (990231), and a Division of Coastal Management Permit (79-99) to
construct a railroad crossing and stormwater management ponds in unnamed intermittent tributaries of
the Chowan River and wetlands adjacent to Brooks Creek in Hertford County, North Carolina. As a
special condition to these permits, Nucor is required to implement mitigation measures outlined in the
Revised Compensatory Wetlands Mitigation Plan Plantation for Nucor Steel Plate Recycling Mill,
Hertford County, November 8, 1999. The Mitigation Plan includes creation of a seven acre bottomland
hardwood wetland and creation of 2.68 acres of littoral shelves along the periphery of four stormwater
ponds, as well as the preservation of 150 acres of swamp forest along the Chowan River and 14.68
acres of wetlands on-site. These mitigation efforts are required to offset unavoidable impacts to 2.32
acres of jurisdictional freshwater wetlands. The as-built monitoring was conducted in May 2002, after
construction and planting of the mitigation areas. The first annual fall monitoring was conducted in
October 2002. As documented in the Fall of 2004, the tree mortality had fallen below the designated
vegetation success criteria. In 2004, a remedial wetland mitigation plan was submitted to the U.S.
Army Corps of Engineers (USACE). This monitoring report indicated that the created wetland was
semi-permanently flooded from 2002 to 2004 and the planted oaks did not survived well, the mean
density of trees per acre fell to 231 which does not meet the required 320 trees per acre outlined in
the original mitigation plan. However, it is important to note that tree survival rates for more water
tolerant species of Taxodium, Nyssa, and Fraxinus, have remained high (79-89% average). This
leads us to conclude that the most significant issue with Quercus tree mortality is long hydroperiods.
A remediation plan was approved December 1, 2004 by the NC Division of Water Quality (DWQ) and
by the USACE on February 15, 2005. In February of 2006, Nucor Steel planted 3,300 trees (Taxodium,
Nyssa, Fraxinus, and fewer Quercus in the highest areas) in the wetland creation area. Nucor also
installed five new hydrology monitoring wells within the creation area and one new well in the
reference wetland in July 2006. This is the second annual report of the remedial wetland activities.
Based on the approved remediation plan, Nucor will continue to monitor the mitigation site and report
the results annually, for the next three years, to the USACE, N.C. Division of Water Quality (DWQ),
and the N.C. Division of Coastal Management (LAMA).

1.0 INTRODUCTION
Nucor Steel (Nucor) was issued a Department of the Army Permit (No. 199811324), a N.C.
Division of Water Quality 401 Certification (990231), and a Division of Coastal Management
Permit (79-99) to construct a railroad crossing and stormwater management ponds in unnamed
intermittent tributaries of the Chowan River and wetlands adjacent to Brooks Creek in Hertford
County, North Carolina (Figure 1). As a special condition to these permits, Nucor is required to
implement mitigation measures outlined in the Revised Compensatory Wetlands Mitigation Plan
Plantation for Nucor Steel Plate Recycling Mill, Hertford County, November 8, 1999 and the
Remedial Wetland Mitigation Plan approved on February 15, 2005.
The Mitigation Plan schedules activities to offset unavoidable impacts to 2.32 acres of jurisdictional
freshwater wetlands/Waters of the U.S. Jurisdictional wetlands are defined by 33 CFR Part
328.3(b) and are protected by The Clean Water Act (33 CFR 1344) which is administered and
enforced by the U.S. Army Corps of Engineers (USACE). Mitigation efforts for the project include
the following:
• 7-acre wetland creation area
• Pond C1 includes 0.604-acres of littoral shelf.
• Pond B 1 includes a 0.917-acres littoral shelf.
• Pond Al includes 0.839-acres littoral shelf.
• Pond A3 includes a 0.504-acres littoral shelf.
• 14.87-acres of Preserved Wetlands on-site
• 150 acres of preserved wetlands off-site
The remedial planting of hydrophytic tree species was conducted at the seven acre wetland creation
area (Figure 3) in the winter of 2006. Hardwood saplings include the following species bald
cypress (Taxodium distichum), green ash (Fraxinus pennslyvanica), laurel oak (Quercus laurifolia),
6

water tupelo (Nyssa biflora), willow oak (Quercus phellos), and water oak (Quercus nigra). Wax
myrtle (Myrica cerifera) was planted along the transition area between the wetland area and the
upland area. Herbaceous species planted on the littoral shelves included pickerel weed (Pontedaria
cordata), arrow arum (Peltandra virginica), soft rush (Juncus effusus), lizard's tail (Saururus
cernuus), shallow sedge (Carex lurida) and uptight sedge (Carex stricta).
The initial planting of hardwood saplings at the creation area was conducted in winter of 2002. Per
the approved remediation plan, additional planting of hardwood saplings was conducted in
February 2006. Planting of herbaceous species was conducted in Pond BI in the spring of 2001
and ponds Cl, A3, and half of pond Al were planted in spring 2002. The remainder of Pond Al
was planted in June of 2002. A total of 5,150 seedling tree species as described above were planted
on at least 6 x 10-foot center spacings (or 726 trees per acre) and approximately 51,885 herbaceous
species were planted on 18-inch spacings per the Revised Compensatory Wetlands Mitigation Plan
for Nucor Steel Plate Recycling Mill (1999). An additional 3,300 hardwood trees were planted in
2006. Monitoring of wetlands will be conducted for five years (2010) with a regulatory review
after the fifth year to determine success. This report summarizes the status and /or success of
remediation actions to date. The fall mitigation monitoring was conducted on September 18 and
19, 2007.
Details of the wetland preservation on-site and off-site were provided in the As-Built report dated
July 16, 2002.

2.0 PURPOSE
In order to demonstrate successful mitigation, the Nucor Steel wetland creation area must be
monitored for both hydrology and vegetation for a minimum of five years or until success criteria
are fulfilled. Success criteria are based on federal guidelines for wetland mitigation. The
following report details the results of hydrologic and vegetative monitoring during the 2007
growing season at the Nucor Steel Hertford County site as well as local climate conditions
throughout the growing season.
The purpose of the long term monitoring program is to quantify the developing structure of the
created bottomland hardwood. Data collected will be used to determine the regeneration and
survivability of planted wetland vegetation, as well as the success of wetland mitigation efforts.
Also a qualitative analysis will be formulated through observations of vegetative growth and
wildlife usage throughout the mitigation areas. The goal of the proposed mitigation is to offset
impacts to on-site wetlands by replacing lost functions and values with equal or higher functions
and values. The primary target functions to be replaced are stormwater storage and filtration
capacities, stormwater transfer, and habitat resources.

3.0 METHODS
As described in the Revised Compensatory Wetlands Mitigation Plan Plantation for Nucor Steel
Plate Recycling Mill, Hertford County (November 1998) prepared for Nucor, monitoring of
wetland vegetation and hydrology was conducted on the mitigation areas. Photographs are taken
' annually to document conditions occurring within the wetlands mitigation sites for future
comparison.
The site was constructed over a year period beginning in the spring of 2001 and fmishing in the
' winter of 2002. Prior to excavation beginning, spot elevations within existing wetland "W/X" were
taken to set the target elevation for the creation area. The target elevation as set forth in the Revised
' Compensatory Wetlands Mitigation Plan Plantation for Nucor Steel Plate Recycling Mill, Hertford
County, November 8, 1999 was 30.5 feet msl. The as-built topographic survey conducted by the
' Bissell Group indicates that the site is close to design elevation. Elevations mostly vary from 30.19
to 30.92 feet msl throughout the site with several small isolated depressions.
The following sections describe the methods that were used to monitor these elements within the
' wetland creation/restoration sites.

1 5.0 HYDROLOGY
5.1 Success Criteria
' In accordance with federal guidelines for wetland mitigation, the success criteria for hydrology
states that the area must be inundated or saturated (within 12" of the surface) by surface or
groundwater for a consecutive 12.5% of the growing season. Areas inundated for less than 5% of
the growing season are always classified as non-wetlands. Areas inundated between 5% - 12.5%
' of the growing season can be classified as wetlands depending upon factors such as the presence
of wetland vegetation and hydric soils. The Revised Compensatory Wetlands Mitigation Plan
' Plantation for Nucor Steel Plate Recycling Mill, Hertford County (November 1998) set a target goal
of saturated soils for at least 22 days of the growing season.
' The growing season in Hertford County begins March 28 and ends November 7. These dates
correspond to a 50% probability that temperatures will drop to 28°F or lower after March 28 and
before November 71. The growing season is 224 days; therefore, optimum hydrology requires
12.5% of this season, or at least 28 consecutive days. A consecutive 10% would be equivalent to
' 22.4 days (rounded to 22 days) and a consecutive 5% would be equivalent to 11.2 days (rounded
to 11 days). Local climate must also represent average conditions for the area.
' 5.2 Hydrologic Description
Five new groundwater-monitoring gauges (Figure 3) and one reference wetland gauge were
installed July 19, 2006, per ERDC TN-WRAP-00-02 entitled, Installing Monitoring
' Wells/Piezometers, dated July 2000, to evaluate hydrology in the wetland creation area, local
climate data, and reference wetland hydrology. The automatic monitoring gauges record daily
' readings of groundwater depth. The Nucor Steel wetland site involved the construction of a
stormwater pond (C 1) adjacent to the wetland. Overflow from the pond enters into the wetland

' creation area using a 300-foot diffuser. This connection should provide adequate hydrologic
' input along with rainfall and groundwater to sustain the necessary hydrology for the wetland area.
The hydrologic monitoring should show the reaction of the groundwater and surface water levels
' to specific rainfall events. Per the approved remedial action plan, Nucor conducted maintenance
of the wells on March 13-14, 2007. The wells were removed from the ground and taken to the
' Nucor facility. The wells were washed using a pressure washer to remove debris and fine
particulates. After cleaning, the wells were re-installed adjacent to their original location and per
' guidelines.
' 5.3 Results of Hydrologic Monitoring
5.3.1 Site Data
' The maximum number of consecutive days that the groundwater was within twelve
' inches of the surface was determined for each gauge. This number was converted into a
percentage of the 224-day growing season. The results are presented in Table 1.
Appendix A contains a plot of the groundwater depth for each monitoring gauge. The
maximum number of consecutive days is noted on each graph. The individual
' precipitation events, shown on the monitoring well graphs as bars, represent data
collected from the rain gauge installed on site. The site was inundated and or saturated to
' the surface during our site visit in March 2007.
Nucor purchased and installed six new automated wells to record the hydrology in the
creation area and in the reference wetland and will conduct routine maintenance on an
annual basis. The maintenance of the wells is performed in March of each monitoring
season. The installation locations of the new wells were recorded to sub-meter accuracy
using a Trimble GeoXT GPS unit and are shown on the enclosed figure.

5.3.2 Climatic Data
Figure 4 represents an examination of the local climate in comparison with historical data
in order to determine whether 2007 was "average" in terms of climate conditions. The
figure compares the on-site rainfall from 2007 with that of historical rainfall (data
collected between 1971 and 2000). The graph shows 2007 rainfall totals from January
2007 through November 2007, which includes the growing season for this site.
5.4 Conclusions
The monitoring wells in the created wetland show saturation and inundation for greater that 12.5
percent of the growing season and represent a successful hydrologic period. The monthly rainfall
totals to date were below the average range for the majority of the growing season.

' 6.0 FALL 2007 VEGETATION
1
The seven acre created wetland is located on the southern site boundary between the railroad
' corridor and adjacent to Bazemore Road (Figure 2). The site encompasses approximately 7 acres of
created wetland. The creation areas was planted with sapling species, including swamp chestnut
' oak, green ash, willow oak, water tupelo, water oak, laurel oak and bald cypress. Based on the
approved remediation plan 3,300 trees were planted in the creation area in the winter of 2006.
' Three transects with a total of seven plots were located within the creation area.
' Vegetation monitoring was conducted in accordance with the Comprehensive Wetland
Determination Methodologies as described in the US Army Corps of Engineers Wetland
' Delineation Manual 1987. Three line transects were established along a baseline transect generally
oriented perpendicular to Bazemore Road. Sample plots were permanently established at random
' within 300-foot intervals in the 7-acre creation area. All transects and plots were marked with
stakes painted a fluorescent color to facilitate identification and future monitoring. Vegetative
' species composition and dominance were measured within each sample plot. Trees were monitored
within 30-foot radius circular plots. Herbaceous vegetation was monitored within 5-foot radius
circular plots. All herbaceous species were identified and the percent area cover recorded for each.
6.1 Success Criteria
Success Criteria requires a minimum mean density of 320 characteristic trees species/acre
surviving for at least five years in the wetland creation area of the site. Characteristic tree species
are those species planted along with natural recruitment of other naturally occurring hydrophytic
species. Sweetgum, red maple, and pines will not be considered in the tally of the 320 trees per
acre. No quantitative sampling success requirements were developed for the herbaceous and
shrub assemblages as part of the vegetation success criteria per the November 2002 mitigation
' plan.

6.4 Created Wetland Vegetation Conclusions
' Seven acres were planted with 5,150 hardwood seedlings (approximately 735 trees per acre) in
March 2002 and seven vegetation monitoring plots were established in the wetland creation area.
' In February 2006, an additional 3,300 trees were planted in the creation area in accordance with
the approved remediation plan. The fall 2007 vegetation monitoring revealed an average density
' of 925 trees per acre well above the 320 tree/acre minimum requirements. There was an increase
' from 830 trees in 2006 to 925 trees in 2007. Most of this increase is the result of multiple-stems
sprouting from the planted Nyssa aquatica.

7.0 SUMMARY 2007
Hydrologic monitoring indicated that the site is consistently meeting the hydrology success
' criteria. The period of inundation/saturation ranged from 16-39% percent of the growing season
(from March 28, 2007 to November 7, 2007). The reference wetland site indicated
' saturation/inundation for 26 percent of the growing season and is consistent with the well
observations from the creation area. Total average tree density across all seven plots was 925
' trees per acre.
Nucor Steel will continue monitoring the site to evaluate hydrologic and vegetation success and
submit those reports to the appropriate agencies on an annual basis.
