Agenda 06/08/2021 Item #16A14 (Commercial Excavation Permit to Stewart Mine)06/08/2021
EXECUTIVE SUMMARY
This item requires that ex parte disclosure be provided by Commission members. Should a hearing
be held on this item, all participants are required to be sworn in. Recommendation to approve
Commercial Excavation Permit PL20200002472 to excavate and remove an additional 23,924,047
cubic yards of material from the expansion of the existing approved Stewart Mine.
OBJECTIVE: To approve Commercial Excavation Permit PL20200002472 for the excavation and
removal of an additional 23,924,047 cubic yards of material from Stewart Mine.
CONSIDERATIONS: On July 26, 2006, the Board of County Commissioners (Board) approved
Commercial Excavation Permit No. 59.868 Stewart Mine, which was the original permit that allowed an
excavation of 24,235,443 cy of fill material.
The applicant wishes to expand operation of an existing commercial excavation, which would increase
the existing mine by 206.7 acres to the west of the current mining operation. This project is designated as
Agricultural (A) Mobile Home Overlay (MHO) Zoning and within the Rural Lands Stewardship Area
(RLSA) Open Lands as identified on the Future Land Use Element (FLUE). Pursuant to the County’s
Comprehensive Plan for the RLSA, the proposed excavation requires a conditional use permit, which was
approved by the Board on January 12, 2021.
Stipulations from the existing permit will be carried over into the subject expansion permit, as described
in the Recommendations section.
FISCAL IMPACT: The applicant has paid $27,970.00 for the Commercial Excavation permit
application and is required to pay an additional $49,331.38 in road impact fees at time of permit issuance.
GROWTH MANAGEMENT PLAN (GMP) IMPACT: This project has been found to be consistent
with the goals, objectives, and policies of the GMP including specifically the Future Land Use Element
(FLUE), Transportation Element, and Conservation and Coastal Management Element (CCME).
ENVIRONMENTAL ISSUES: Offsite hauling of excess fill, if done properly, will have no
environmental impact. There are no wetlands being preserved on this site. Pursuant to the FDEP Permit,
the permittee has mitigated for impacts pursuant to the Environmental Resource Permit regulations. There
are no Collier County required preserves, as the land has been cleared for agricultural use and maintained
clear of native vegetation (LDC section 4.08.05.J.2.).
LEGAL CONSIDERATIONS: The Petitioner is requesting a Commercial Excavation Permit under
Section 22-110 of the Collier County Code of Laws and Ordinances. The attached staff report and
recommendations of the Collier County Planning Commission (CCPC) acting as the Environmental
Advisory Council (EAC) are advisory only and are not binding on you. All testimony given must be
under oath. The Petitioner has the burden to prove that the proposed Commercial Excavation is consistent
with all the criteria set forth below, and you may question the Petitioner, or staff, to satisfy yourself that
the necessary criteria have been satisfied under Section 22-110(d) of the Collier County Code of Laws
and Ordinances. Should you consider denying the Commercial Excavation Permit, to assure that your
decision is not later found to be arbitrary, discriminatory or unreasonable: the denial must be based upon
competent, substantial evidence that the proposal does not meet one or more of the listed criteria below.
Criteria for Commercial Excavations
(1) The excavation will not interfere with the natural function of any sanitary, storm or drainage
system, or natural flow way, whether public or private, so as to create flooding or public health
hazards or jeopardize the functions of the natural resources and environment of Collier County.

06/08/2021
(2) Dust or noise generated by the excavation will not cause a violation of any applicable provisions of
this article. Rock crushing operations or material stockpiles that will be adjacent to any existing
residential area may require separate county approval. It is anticipated that these activities will not
occur during this operation.
(3) The excavation will not adversely affect groundwater levels, water quality, hydro-period, or surface
water flow ways. The county manager or his designee may require the applicant to monitor the quality
of the water in the excavation and adjacent ground and surface waters. Under no circumstances shall
the excavation be conducted in such a manner as to violate Collier County or applicable State of Florida
water quality standards.
(4) The excavation will be constructed so as to not cause an apparent safety hazard to persons or
property.
(5) The excavation does not conflict with the growth management plan or land development regulations
adopted pursuant thereto, nor does it conflict with existing zoning regulations. Special criteria and
approval procedures may be necessary for projects within the Big Cypress Area of critical state
concern.
(6) In cases where a wetland is no longer capable of performing environmental functions or providing
environmental values or in cases where it is determined that no reasonable alternative exists ot her than
disrupting a wetland, certain alterations may be allowed, except as otherwise authorized through
previous county review processes.
(7) Flow of water within and through preserved wetlands shall not be impeded.
(8) Appropriate sediment control devices (hay bales, silt screens, etc.) shall be employed to prevent
sedimentation within the wetland pursuant to the design requirements of Section 10.02.02 of the Land
Development Code. Any building site adjacent to a wetland and elevated by filling, must employ the
same erosion control devices. Fill must be stabilized using sod, seed, or mulch.
This item is approved as to form and legality and requires a majority vote for Board approval. - DDP
EAC RECOMMENDATIONS: On May 6, 2021, the Collier County Planning Commission (CCPC),
acting in their role of the Environmental Advisory Council (EAC), voted 6-0 to send a recommendation
for approval to the Board of County Commissioners (Board), with stipulations recommended by staff.
RECOMMENDATIONS: Recommendation that the Board of County Commissioners (Board) approves
the excavation and removal of an additional 23,924,0047 cubic yards of fill within the Stewart Mine
pursuant to Commercial Excavation Permit PL20200002472, subject to existing stipulations in the
previously approved Commercial Excavation Permit No. 59.868, as described in the attached document

HISTORY AND PERMITS
This project is within the Open Lands of the RLSAO and pursuant to the County’s Comprehensive
Plan for the RLSA, the proposed excavation requires approval of a Conditional Use petition. The
Conditional Use for the proposed mine expansion site was approved by the Collier County
Planning Commission on December 3, 2020 and by the Board of County Commissioners on
January 12, 2021 (Resolution 21-13).
On July 26, 2006, the BCC approved Commercial Excavation Permit No. 59.868, which was the
original permit that allowed excavation of 24,235,443 cy of fill material.
GROWTH MANAGEMENT (GMP) CONSISTENCY:
This project has been found to be consistent with the goals, objectives, and policies of the GMP,
including specifically the three elements analyzed below:
1) FUTURE LAND USE ELEMENT (FLUE):
The subject property is consistent with the FLUE. The subject property is designed
Agricultural/Rural and within the Rural Lands Stewardship Overlay (RLSAO), as shown on the
Future Land Use Map (FLUM) and in the Future Land Use Element (FLUE) of the GMP. On the
Stewardship Overlay Map, part of the FLUM, the site is designated as “Open.” The “A” zoning
16.A.14.a
Packet Pg. 716 Attachment: CCPC Staff Report (15835 : Commercial Excavation Approval - Stewart Materials, LLC)
PL20200002472, 2315 Edwards Grove Road

district allows a conditional use for an extraction or earth mining use, as listed in the Land
Development Code (LDC) Chapter 2.03.01.A.1.c.1.
The FLUE states the goal of the RLSAO is to address long-term needs of residents and property
owners within the Immokalee Area Study boundary of the Collier County Rural and Agricultural
Area Assessment by protecting agricultural activities, preventing the premature conversion of
agricultural land to non-agricultural uses, directing incompatible uses away from wetlands and
upland habitat, enabling the conversion of rural land to other uses in appropriate locations,
discouraging urban sprawl, and encouraging development that implements creating land use
planning techniques. RLSA Policies 1.4 and 1.5 provide that properties within the RLSA may
develop per the “Baseline Standards” (uses allowed by the underlying “A” zoning and
Agricultural/Rural FLUM designation), which includes earth mining by conditional use.
2) TRANSPORTATION ELEMENT:
Transportation Planning staff has reviewed the proposed Commercial Excavation and has
approved the project including the stipulations of approval listed in the Conditional Use, including
the limiting of truck traffic to a maximum of 49 pm peak hour, two-way trips, per the approved
Conditional Use (Resolution 21-13).
3) CONSERVATION AND COASTAL MANAGEMENT ELEMENT (CCME):
Environmental Planning staff has reviewed this petition and confirmed that the CCME does not
apply, as the FLUE only requires the property to comply with the RLSA environmental
regulations. Therefore, the property is not required to meet the environmental policies of the
CCME.
STAFF ANALYSIS:
Staff has completed a comprehensive evaluation of this petition including the criteria upon which
a recommendation must be based. Section 22-110 (b)(2) of the Collier County Code of Laws and
Ordinances specifies the requirements for the Commercial Excavation permit. The specific criteria
are as follows:
A. The excavation will not interfere with the natural function of any sanitary, storm or drainage
system, or natural flow way, whether public or private, so as to create flooding or public health
hazards or jeopardize the functions of the natural resources and environment of Collier County.
Staff Comment: Staff has reviewed the Excavation Permit and has verified that this
excavation will not interfere with the natural function of any sanitary, storm or drainage
system, or natural flow way, whether public or private, so as to create flooding or public
health hazards or jeopardize the functions of the natural resources and environment of
Collier County.
B. Dust or noise generated by the excavation will not cause a violation of any applicable
provisions of this article. Rock crushing operations or material stockpiles that will be adjacent to
any existing residential area may require separate county approval. It is anticipated that these
activities will not occur during this operation.

Staff Comment: There are 7 property owners within 300 feet of the property boundary.
An attached aerial depicts the location. Pursuant to Section 22-110 (c) of the Code of
Laws and Ordinances, letters have been sent to all property owners within 300 feet of the
site advising them of this petition and the EAC and BCC meeting dates. Additionally,
signs will be posted in the area providing notice of the meeting before the Board of
County Commissioners. The applicant has provided a Dust Control Plan within the Site
Plan to provide reasonable assurances of dust control. A stipulation of the approved
Conditional Use (Resolution 21-13) requires that Edwards Grove Road shall be paved a
minimum of 22 feet in width and a depth of 1.5 inches of asphalt or asphalt millings for
the duration of the mining operation. Considering the location of the subject site and the
commercial excavation operation currently operating to the east, there is no additional
noise anticipated.
C. The excavation will not adversely affect groundwater levels, water quality, hydro-period, or
surface water flow ways. The County Manager or his designee may require the applicant to
monitor the quality of the water in the excavation and adjacent ground and surface waters. Under
no circumstances shall the excavation be conducted in such a manner as to violate Collier County
or applicate State of Florida water quality standards.
Staff Comment: Staff has determined that the excavation will not adversely affect
groundwater levels, water quality, hydro-period or surface water flow ways.
D. The excavation will be constructed so as to not cause an apparent safety hazard to persons or
property.
Staff Comment: Staff has determined that the excavation follows OSHA guidelines and the
County Code of Laws with respect to the excavation operation so as to not cause an
apparent safety hazard to persons or property.
E. The excavation does not conflict with the growth management plan or land development
regulations adopted pursuant thereto, nor does it conflict with existing zoning regulations. Special
criteria and approval procedures may be necessary for projects within the Big Cypress Area of
Critical State Concern.
Staff Comment: Staff has determined that the excavation does not conflict with the
Growth Management Plan or Land Development Code regulations. The project is not
located within the Big Cypress Area of Critical State Concern.
F. In cases where a wetland is no longer capable of performing environmental functions or
providing environmental value or in cases where it is determined that no reasonable alternative
exists other than disrupting a wetland, certain alterations may be allowed, except as otherwise
authorized through previous county review processes.

Staff Comment: The Environmental Data indicates the property consists entirely of lands
that have been in active agriculture and no native vegetation exists on site. Therefore, no
wetlands will be impacted.
G. Flow of water within and through preserved wetlands shall not be impeded.
Staff Comment: There are no wetlands on this site. There are no Collier County required
preserves, as the land has been historically cleared for agricultural use and maintained
clear of native vegetation (LDC 4.08.05.J.2).
H. Appropriate sediment control devices (hay bales, silt screens, etc.) shall be employed to
prevent sedimentation within the wetland pursuant to the design requirements of Section 10.02.02
of the Land Development Code. Any building site adjacent to a wetland and elevated by filling,
must employ the same erosion control devices. Fill must be stabilized using sod, seed, or mulch.
Staff Comment: Staff has reviewed the Commercial Excavation Permit and the plans
indicate appropriate measures to prevent sedimentation and erosion control.
This project has been found to be consistent with the requirements of Chapter 22, Article IV of the
Code of Laws and Ordinances.
COUNTY ATTORNEY OFFICE REVIEW:
The County Attorney’s Office has reviewed the staff report EX-PL20200002472 on April 19,
2021.
RECOMMENDATION:
Staff recommends the Collier County Planning Commission, acting as the Environmental Advisory
Council (EAC), forward Petition PL20200002472 to the Board of County Commissioners with a
recommendation for approval, including all the previously approved excavation permit conditions and
Conditional Use stipulations of approval.

Environmental Resource Permit
PERMITTEE: Permit number: MMR_228414-005
Stewart Materials, LLC. Date of Issue: 3/19/2020
c/o Nick Stewart, CEO Expiration of Construction Phase:
2875 Jupiter Park Drive, Suite 1100 3/19/2045
Jupiter, Florida 33458 County: Collier
Project: Immokalee Sand Mine
PROJECT LOCATION:
The mine is located approximately 1.25 miles southwest of the intersection of State Road
29 and State Road 82, northwest of Immokalee, in Sections 18 and 19, Township 46
South, Range 29 East, Collier County, Florida.
PROJECT DESCRIPTION:
The project is an Environmental Resource Permit (ERP) to expand an existing surface
water management system at the Immokalee Sand Mine in Collier County. The currently
permitted site consists of 219.8 acres, which includes a 17.92-acre processing plant site.
The proposed expansion area adjoins the currently permitted site to the west, and adds
231.0 acres to the project, 220.69 acres of which will be mined for sand. Additionally,
the plant site within the currently permitted site will be mined towards the end of the
mining operation, at which point a portable plant facility will be used for processing. The
addition of the 231.0-acre expansion area will bring the total permit area to 450.8 acres
and the additional 238.61 acres of proposed mining will bring the total mining area to
422.31 acres.
Mining will be conducted using a dredge, so no dewatering will occur. The mine
operates under Water Use Permit No. 11-02875-W from the South Florida Water
Management District, which addresses materials washing and pumping. A total of 2.68
acres of impervious surface were previously permitted in association with the plant site
and driveway. No additional impervious surface is being proposed.
The predominant land cover within the proposed expansion area consists of citrus groves.
No jurisdictional wetlands were identified onsite. A total of 10.2 acres of upland cut
ditches with low habitat value will be impacted but will not require mitigation.
Permittee: Stewart Materials, LLC.
Project: Immokalee Sand Mine
File No. MMR_228414-007
Page 2 of 16
All material mined within the expansion area will be piped back to the existing plant site
and processing facility located within the currently permitted site. Additionally, the same
Best Management Practices, Erosion Control Measures, and Pollution Prevention Plan
associated with the current permitted operation will continue to be used for the proposed
expansion. The depth of mining will be 85 feet below natural grade which is about
negative (-) 51 feet National Geodetic Vertical Datum (NGVD).
The proposed mining will be subject to the mandatory reclamation requirements of
Chapter 62C-39, Florida Administrative Code (F.A.C.). At completion, the mining and
reclamation will result in a single, 415.27-acre rectangular lake surrounded by gently
sloping littoral zone wetlands vegetated with native herbaceous plants. The surrounding
upland buffer around the lake will be reclaimed to 35.53 acres of rangeland.
The estimated life of the mine is twenty years. The construction phase, including
reclamation, of this permit expires in twenty years. The post reclamation land types will
include lake, herbaceous wetlands, and rangeland.

STORMWATER MANAGEMENT CALCULATIONS
The stormwater management calculations for Stewart Materials Inc. Immokalee Mine
Expansion were performed to evaluate the stormwater runoff and storage associated with
the mining and post-mining conditions of the existing permitted area and the proposed
expansion area. The storage calculations were performed using a seasonal high water level
(SHWL) of 34.0 feet-NGVD (FDEP ERP 0228414-003) and a rainfall depth of 10.2 inches
for the 25-year, 72-hour storm event obtained from the NOAA Atlas 14, Volume 9, Version
2 for Immokalee, Florida (refer to Exhibit 1). The existing permitted area and the proposed
expansion area are divided into two drainage areas during the pre-mining phase conditions
with a total area of 447.95 acres (refer to Exhibit 2). The stormwater management
calculations indicate that both the proposed mine pit and post-mining lake will provide
sufficient storage to retain the total runoff volume from the 25-year, 72-hour storm event.
No discharges are expected from the mine pits and lakes during the mining and post-mining
phase conditions, respectively.
MINING PHASE
The worst case scenario during mining would occur after the topsoil has been removed and
relocated to the perimeter of the mining area to create a berm, and before any excavation
has commenced. At this time, the site itself would be utilized as the stormwater pond for
any rainfall falling on the proposed site. The top of the berm surrounding the mining area
will need to be a minimum of one (1) foot above existing grade to retain the total runoff
volume generated by the 25-year, 72-hour storm event. As shown on the proposed Mine
Site Plan, the topsoil will be stored to a minimum height of five (5) feet above grade,
allowing more than four (4) feet of freeboard. Additionally, the removal of the overburden
itself will create supplementary stormwater storage volume between the existing grade and
the SHWL. The existing permitted area and the proposed expansion area are comprised of
one drainage area during the mining phase conditions with a total area of 438.31 acres
(refer to Exhibit 3). The total drainage area was defined using the top of the berm.
POST - MINING PHASE
Upon completion of mining operations, the berm surrounding the site will be reduced to a
minimum elevation of 36 feet-NGVD and the extraction site will be converted into a lake.
The top of the berm of the existing permitted area and proposed expansion area is
considered the limit of the drainage basin. The post-mining phase drainage area will be
approximately 433.77 acres (refer to Exhibit 4). The total drainage area was defined using
the top of the berm. The lowest outfall elevation will be 36 feet-NGVD. The available
storage volume in the lake was calculated using a SHWL of 34.0 feet-NGVD and 100 %
impervious basin area.
Runoff Volume = (433.77 ac x 10.2 in/12 in) = 368.70 ac-ft
KLF Project #20180455.001A Page 4 of 5 December 2017
MOU17R66725
Available Storage Volume (V): The proposed post-mining phase lake is 417.61 acres at
the SHWL of 34 ft-NGVD and 419.96 acres at the top of berm (internal area) of 36 ft-
NGVD. The difference in elevation within the available storage volume is 2 feet.
V = [(417.61 + 419.96)/2] x 2 = 837.57 ac-ft
Freeboard Calculation (FB):
V = [(A1 + A2)/2] x H
𝑯= 𝑉
(𝐴1 +𝐴2
2 )
Where;
V = runoff volume, ac-ft
A1 = lake area at the SHWL, acres
A2 = lake area at the top of berm, acres
H = water depth above the SHWL, ft
𝑯= 368.70
(417.61 +419.96
2 )
H = 0.88 ft
The water level (WL) in the lake after the 25-year, 24-hour storm event is equal to the
SHWL plus H.
WL = 34.00 + 0.88 = 34.88 feet-NGVD
FB = top of berm elevation – WL
FB = 36.00 – 34.88 = 1.12 feet
The lake will retain the total runoff volume from the 25-year, 72-hour storm event and
provide a freeboard of approximately 1.12 feet.

1 Precipitation frequency (PF) estimates in this table are based on frequency analysis of partial duration series (PDS).
Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates
(for a given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper
bounds are not checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.
Please refer to NOAA Atlas 14 document for more information.

1.0 INTRODUCTION
The purpose of this monitoring plan is to outline the water quality monitoring and
reporting at the Stewart Materials, Immokalee Sand Mine, in association with an
Environmental Resource Permit (ERP) application proposing a westward expansion.
Proposed monitoring will involve groundwater quality sampling from one downgradient
monitoring well located south of the proposed mine lake as shown in Figure 1. The
active commercial sand mine operation and the proposed westward expansion are
located approximately 1.25 miles southwest of the intersection of State Road 29 and
State Road 82, northwest of Immokalee, in Sections 18 and 19, Township 46 South,
Range 29 East, Collier County, Florida. This groundwater quality monitoring plan is
prepared in fulfillment of Section 8.3.2 of the Statewide Environmental Resource Permit
(SWERP) Applicant’s Handbook, Volume I, which requires that Class G-I and G-II
groundwater meet primary and secondary drinking water quality standards for public
water systems established pursuant to Sections 403.850 through 403.864, F.S., and
listed in Chapters 62-550.310 and 62-550.320, F.A.C.
2.0 WATER QUALITY MONITORING PLAN
The purpose of the monitoring program is to meet the requirement of Section 8.3.2 of the
SWERP Applicant’s Handbook, Volume I. The establishment of a monitoring program will
allow 1) background water quality levels to be determined prior to mining, and 2) water
quality levels over the course of mining to be monitored in relation to background levels
and water quality standards. A Water Quality Monitoring Report will be included with the
Annual Mining Status Report submitted each year to the FDEP.
2.1 Monitoring Location
2.1.1 Surficial Aquifer Monitoring Well
The proposed Water Quality Monitoring Well (WQMW), identified as
WQMW-1 will be located south of the proposed mine lake expansion
(Figure 1). The monitoring well will be installed to total depths of
approximately 15 feet below land surface (bls), with 2-inch diameter PVC
casing extending to approximately 5 feet bls and 2-inch diameter PVC
screen from approximately 5 to 15 feet bls. The filter pack will consist of
silica sand to within 2 feet of land surface. The filter pack and screen slots
will be sized such that the slot size retains at least 90% of the filter pack
material. A bentonite well seal, approximately 0.5-foot thick, will be
emplaced on top of the filter pack. The bentonite seal will be topped with
Portland cement to land surface. A vent hole will be drilled in the casing
extending above land surface. Monitor well surface completion will include
installation of a protective well cover and 2-feet by 2-feet concrete pads. The
concrete pad will slope away from the wellhead to facilitate drainage.

The well will be developed by either over-pumping or air lift until free of
drilling fluid, cuttings, or other materials introduced during construction.
Turbidity will be field monitored during development to ascertain an
acceptable reduction in turbidity has been achieved, and levels have
stabilized. A minimum of 5 well volumes will be purged during development,
in addition to 5 times the equivalent volumes of fluids lost to the formation
during drilling.
The well will be constructed by a licensed water well contractor, and a
Florida-licensed professional geologist will be on site during construction to
log well cuttings and verify construction details. Well construction and
development details will be properly documented in the field by a qualified
professional (e.g. geologist or engineer). A licensed professional surveyor
and mapper will survey the elevation of a vertical measuring point on the
casing of the well and at land surface, referenced to the NAVD 1988 vertical
datum. Well elevation will be surveyed to a precision of +/- 0.01-foot. The
licensed surveyor will also survey horizontal coordinates of the well in
Florida State Plane East Zone (NAD 83, feet) coordinates. The FDEP will be
provided a minimum of 72-hours notice prior to installation of the monitoring
well.
Well construction activities will be documented, including final well
construction details and quantities of materials used, development duration
and rate, turbidity values measured during development, and final surveyed
elevations and well horizontal coordinates. Within 30 days of installation, a
well completion report and lithologic description for the well will be provided
to the FDEP using the appropriate agency form.
2.2 Groundwater Monitoring
2.2.1 Background Monitoring
Background sampling will be conducted for primary and secondary
drinking water analytes, per Chapter 62-550, F.A.C. Data collection in the
expansion area will be conducted semi-annually in the year prior to mining
on the expansion area to capture a wet season and dry season cycle.
Sampling will occur per the FDEP Standard Operating Procedures (SOPs)
found in Chapter 62-160, F.A.C. Samples will be analyzed by a National
Environmental Laboratory Accreditation Program (NELAP) laboratory
certified by the Department of Health (DOH).
Groundwater samples will be collected using a peristaltic pump and new
disposable tubing. The well will be purged until field parameters
(temperature, specific conductance, dissolved oxygen, and turbidity) are
stable as determined by a properly calibrated meter. Following
stabilization of field parameters, samples will be collected from the
5
monitoring well, placed into laboratory-supplied containers, and
immediately placed into a laboratory-supplied cooler with wet ice. Packing,
transport, and handling of samples will comply with appropriate
temperatures and hold times prior to analysis.
Primary and Secondary Drinking Water parameters (from Chapter 62-550,
F.A.C.) shown in Table 1 below will be sampled and analyzed as part of
background sampling for the monitoring well. Results obtained for the
expansion area prior to the commencement of mining will be considered
existing background water quality levels. Based on the sampling results,
the groundwater in the expansion area will be classified as defined in
Chapter 62-520, F.A.C. prior to the commencement of mining

2.2.2 Annual Monitoring
Previous groundwater characterization conducted in association with the
application for ERP No. MMR_228414-005 did not detect any tested
analytes at levels exceeding applicable water quality standards. Additionally,
no chemical additives, except water conditioners or FDEP approved pH
adjusters have been authorized by permit for water used in association with
transport, washing, and/or processing the sand. Because there is no record
of water quality pollution and no chemical additives are being used in
association with the mining operation, a frequency of annual monitoring was
deemed appropriate.
Following background monitoring, water quality samples will be collected
annually from WQMW-1 and analyzed for the parameters shown below in
Table 2. Results of the annual water quality sampling results will be
compared with background results and graphed as a function of time in
order to determine the development of any deviations or adverse trends
associated with mining. Annual monitoring results will be submitted to the
FDEP as part of the Annual Mining Report submitted to the FDEP.
Monitoring will continue a minimum of three years following the
commencement of mining after which the applicant may request the removal
of the groundwater monitoring requirement, if concentrations are either less
than the drinking water standards or do not exceed established background
values by greater than 10%.

If any of the minimum groundwater quality criteria or natural background
levels are exceeded during annual monitoring, the FDEP shall be notified
within one week of receipt of the sample results, after which any parameters
exceeding minimum criteria will be resampled and testing results provided to
the FDEP within 14 days of resampling. If any parameters are still in
exceedance of minimum criteria following resampling, an analysis of the
cause of exceedance and a remediation plan to modify the mining operation
as needed to restore the parameters to the minimum criteria will be provided
to the FDEP within 30 days.
