Monitoring Overview
The following describes the Stream &Wetland Monitoring Plan for the monitoring of
select jurisdictional waters during clearing/grading, excavation, and subsequent
pumping(dewatering)operations associated with proposed Wake Stone Corporation
(WSC)Triangle Quarry pit expansion in Wake County, NC. The location of the proposed
pit expansion is shown on the WSC Site Plan.
Portions of the proposed pit expansion boundary are adjacent to three (3)jurisdictional
waters (as determined by the U.S.Army Corps of Engineers (USACE)) and include an
intermittent stream and a perennial stream (per a previous NCDEQ Division of Water
Resources(DWR) onsite determination) identified as Stream 2 and Stream 5,
respectively, and a wetland identified as Wetland 1. The locations of these waters are
shown on the Wetland Survey Plat Map attached to the USACE Approved Jurisdictional
Determination dated January 15, 2020. The classifications of the streams are
documented in the DWR Buffer Determination Letter.
Based on the expected quarry expansion timeline, monitoring will be implemented upon
approval of this Monitoring Plan by NC DEMLR such that baseline data for Stream 2,
Stream 5 and Wetland 1 will be collected for a period of at least 12 months prior to the
commencement of overburden stripping and pit development within the affected
watersheds. Limited clearing for and installation of erosion control measures,
specifically Temporary Basin#3 and associated diversions (as illustrated on the
approved site plans) will occur during the initial 12-month baseline monitoring period.
Clearing for and installation of additional erosion control measures(Temporary Basins
#1 and#2 and associated diversions) may also occur during the baseline period, and the
perimeter access road, sound/visual barrier wall,the bridge crossing of Crabtree Creek,
and security fence (as indicated on the approved site plans) may also be constructed
during this time.
Stream Monitoring
Streams 2 and 5 will be monitored at regularly scheduled intervals using generally
accepted stream evaluation methods and photographic documentation for the life
of the monitoring plan. The primary basis of the monitoring will be classification
criteria described in the most current version of the "NC DWQ-Methodology for
Identification of Intermittent and Perennial Streams and Their Origins" (currently
version 4.11). N.C. Stream Assessment Method (NC SAM)will also be used to
provide supplemental data to evaluate the level of stream function. The intent of
this monitoring is to determine what, if any, changes occur to the intermittent and
perennial classifications of the streams.
During each monitoring visit,the length of each stream will be traversed to observe
its general condition and apparent function. The streams will be evaluated per the
NC DWQ methodology considering geomorphic indicators, hydrologic indicators, and
biological indicators and an NC DWQ Stream Identification Form completed. The

streams will also be photographed (from similar pre-established vantage points
along their length) during each monitoring visit to document its condition. Not less
than four(4) photo points will be established along each stream. Copies of the NC
DWQ Stream Identification Forms, photographs from each site visit and other
pertinent information will be included in an annual monitoring report.
NOTE: if it is determined that Stream 2 is no longer considered intermittent
and/or Stream 5 is no longer considered perennial, either during site monitoring
or associated with a reissuance of the June 20, 2019 buffer determination letter,
then DWR and DEMLR will be notified, and a site visit scheduled to further
evaluate the streams to consider if the adjacent pit expansion activities are
negatively affecting the function of the streams. if DWR and DEMLR determine
that activities associated with the pit expansion were the clear cause of the
change in the stream classification(s) (and no other potential causes)can be
identified), then WSC will develop a remediation method or mitigative measures
to be approved by NC DEMLR in coordination with DWR and USACE to rectify the
dewatering.
Wetland Monitoring
Wetland 1 will be monitored at regularly scheduled intervals using a combination of
hydrology,vegetation, soils, and photographic documentation for the life of the
monitoring plan. The intent of this monitoring is to determine what, if any, changes
occur to the overall function of the wetland including shallow groundwater levels
within the wetland itself.
Hydrologic monitoring will include the installation of a single groundwater gauge
within the wetland to measure the depth of shallow groundwater(relative to the
ground surface). An Infinities USA, Inc. pressure water level data logger will be
installed as shown in the attached Gauge Installation Detail. The gauge will be set to
record a single daily groundwater reading(typically early morning). The recorded
gauge data will be downloaded on a regular basis and collected data will be
processed for inclusion in monitoring reports. The gauge will be installed prior to
the commencement of site clearing/grading and will be monitored continuously
throughout pit expansion activities.
In addition to gauge download, during each monitoring visit observational
monitoring and documentation of the wetland will be performed. Monitoring will
include documentation of existing wetland vegetation, as well as surface hydrologic
indicators (standing water,staining of vegetation, wrack lines, etc.). During each
visit,the wetland will be photographed (from similar pre-established vantage points)
to document its physical condition. Not less than two (2) photo points will be
established within the wetland. During the last monitoring visit of each monitoring
year a hand auger will be advanced within the wetland area to develop a soil profile
(typically 12-to 18-inches deep)to evaluate shallow soil conditions. N.C.Wetland
Assessment Method (NC WAM)will also be used to provide supplemental data to
evaluate the level of wetland function.

Rainfall Monitoring
For comparison with collected shallow groundwater data,site rainfall data will be
collected using a single Infinities USA, Inc. rain gauge data logger installed at a
location in the general vicinity of the proposed pit expansion. The rain gauge will be
downloaded on a regularly scheduled basis and data processed in conjunction with
the shallow groundwater gauge within the wetland and collected data processed for
inclusion in monitoring reports. As necessary this data will be supplemented with
normally collected rainfall data (at the site quarry office) and/or available on-line
local rainfall data.
Monitoring Frequency
Upon approval of this Monitoring Plan,the monitoring of Stream 2,Stream 5 and
Wetland 1 will be performed as follows:
a. Site monitoring visits for the evaluation of Stream 2,Stream 5 and Wetland
1, including the download of hydrology and rainfall gauge data, and site
documentation (field notes, stream forms, photos,etc.)will be performed
quarterly for the life of the monitoring plan, except that NC SAM and NC
WAM assessments will be performed twice per year(July and January).
b. The life of the monitoring plan will comprise duration of quarry expansion
activities including and up to the completion of pumping (dewatering)
operations or until such time as NC DEMLR deems monitoring activities
unnecessary.
NOTE. At any point during site monitoring, based upon site conditions
and the recorded results of the stream and wetland monitoring, a request
may be made by NC DEMLR or Woke Stone to alter the frequency of site
monitoring visits or to release the project from future stream and/or
wetland monitoring requirements altogether. if any stream or wetland
feature identified in this monitoring plan is determined to be no longer
jurisdictional by any subsequent USACE Approved Jurisdictional
Determination, and this change in status is unrelated to mining activities,
Wake Stone shall be released from the monitoring requirement for that
feature.
Monitoring Reporting
Reporting of site monitoring activities will consist of the following:
Quarterly Reports
a. Quarterly written reports to NC DEMLR briefly summarizing the monitoring
for Stream 2, Stream 5 and Wetland 1 for the previous quarter. The report
will include the date of each site monitoring visit, a qualitative description of
Page 3 of 5

site conditions in the vicinity of Stream 2, Stream 5 and Wetland 1, prepared
NC DWQ Stream Identification Forms, sequential photographs of each photo
point, year to date shallow groundwater gauge and rain gauge monitoring
data, and most recent NC SAM and NC WAM results.
b. Quarterly monitoring reports will be submitted to NC DEMLR by the end of
the month following the end of the monitoring quarter(e.g.the first
quarter's report (July through September monitoring)will be submitted by
the end of October, etc.).
Annual Reports
a. An annual written report to NC DEMLR summarizing the previous year's
monitoring activities and results, and site observations along the streams and
within the wetland. The report will include any available monitoring data for
the previous three years and an opinion regarding what effects, if any,were
realized on Stream 2,Stream 5 and Wetland 1, as a result of site
clearing/grading operations, pit excavation and dewatering operations during
the monitoring year.
b. The annual report will include a general description of site quarry activities
during the reporting period,the date of each site monitoring visit, a
qualitative description of site conditions in the vicinity of Stream 2,Stream 5
and Wetland 1, prepared NC DWQ Stream Identification Forms, sequential
photographs of each photo point, shallow groundwater gauge and rain gauge
monitoring data, a description of any repairs or replacement of monitoring
devices including dates of completion, and other noteworthy observations.
The report will also include NC SAM/NC WAM results, and a general
description of quarry expansion activities anticipated within the upcoming
monitoring year and any associated resultant changes in site monitoring
activities.
c. The annual monitoring report will be submitted to NC DEMLR by September
15t of each year for the previous year's monitoring. The monitoring year shall
run from July 1 to June 30.
NOTE: Observed changes in stream or wetland characteristics, or gauge
registered indicators of negative effect on shallow groundwater
hydrology(potentially due to quarry operations)will be noted and
reported to NC DEMLR within three(3)business days of identification. If
deemed necessary, based on indicators and at the direction of NC DEMLR,
in coordination with DWR and USACE a plan will be developed to
augment stream and/or wetland hydrology, or provide other such
mitigation as deemed acceptable to DWR and USACE. Details of any such
plan will be coordinated with and approved by regulatory agencies at that
time.
