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 location of these waters are
shown on the Approved Jurisdictional Determination Wetland Survey Plat Map. 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 and issuance of the Mining Permit Modification 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 site clearing/grading
operations within the affected watershed.
Stream Monitoring
Streams 2 and 5 will be monitored on 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). 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 the stream will be traversed to observe
its general condition and apparent function. The stream 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
stream will also be photographed (from similar pre -established vantage points along
its 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.
(VOTE. NC DWR will be requested to renew the buffer determination letter for the
quarry property at the time of its expiration on June 20, 2024. 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 at the time of reissuance of
the buffer determination letter, then DWR 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 it is
determined that activities associated with the pit expansion were the clear cause
of the change in the stream classification(s) (and no other potential cause(s) can
be identified), then WSC will develop a remediation method or mitigative
measures to be approved by NC DENILR in coordination with DWR and USACE to
rectify the dewatering.
Wetland Monitoring
Wetland 1 will be monitored on regular 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 the monitoring report. 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.
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 the monitoring report. As necessary this data will be supplemented with
normally collected rainfall data (at the site office) and/or available on-line local
rainfall data.

Monitoring Frequency
Upon approval of this Monitoring Plan and issuance of the Mining Permit Modification,
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
monthly for the life of the monitoring plan.
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 Wake Stone to alter the frequency of site
monitoring visits or release the project from future stream and/or
wetland monitoring requirements altogether.
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
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, and year to date shallow groundwater gauge and rain gauge
monitoring results.
b. Quarterly monitoring reports will be submitted to NC DEMLR by the end of
the month following the end of the monitoring quarter (ie. the first quarter's
report will be submitted by the end of April, 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 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 results, a description of any repairs or replacement of monitoring
devices including dates of completion, and other noteworthy observations.
The report will include 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 January 31st
of each year for the previous year's monitoring.
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. Details of any such plan will
be coordinated with and approved by regulatory agencies at that time.
These measures could include but are not limited to providing augmented
flow from onsite sources.
Monitoring Records
A copy of this Stream & Wetland Monitoring Plan and records of all monitoring activities
and data, maintenance and repair activities, annual monitoring reports and other
pertinent correspondence will be maintained by the Permittee on site. Records of any
or all such documentation will be made available to NC DEMLR upon request.
