Subject: comments on Viewmont Sandrock LCID Permit Application, 41R-LCID-2011, DIN 27468

Hi David:

The Solid Waste Section (SWS) completes a review of the permit amendment application (DIN 27441) and has several comments
(DIN 27468) on the permit application, which are stated below:

DIN 27468
General
1. Throughout the permit application several title or name of the LCIDLF facility are used: Viewmont Road LCID or Viewmont
Quarry LCID. For the sake of consistency and avoid any confusion please use one correct landfill facility name. (please noted
that current permit is issued to construct and operate the Viewmont Road LCID Landfill.

The facility is heretofore identified as Viewmont Quarry LCID. Corrections to this effect have been made throughout the text.

2. Throughout the permit application, please state the name of the landfill property owner. According to the result of a deed
search, the landfill property is owned by Martin Marietta Materials Real Estate Investments, Inc. And please state the
business relationship between Martin Marietta Materials Real Estate Investments, Inc. and Martin Marietta Materials, Inc.
in the permit application.

MMMREI is the land holding company, in which the land title is held. The owner/operator is Martin Marietta Materials, Inc. This
relationship has been clarified on Page 1 in the text.

Part 1 - Facility Plan
3. (Section 1.1) According to the data in Drawing No. E3/Sheet No. 7, the proposed landfill unit - Phases 1
& 2 on the south side of the on-site, unnamed tributary encompasses 12.6 acres, not 12.4 acres as described in the
section. Please provide the consistent data.

The drawings have been corrected to be consistent with the text.

4. (Section 1.1) Regarding the operation of the LCID Processing Facility, please provide the following information for
clarification:
i. (On Page 1, the second paragraph) The subsection describes that a LCID Processing Facility (permitted as a
“two-acre stockpile”) exists outside the boundary of Solid Waste Permit# 41-
R. Is this facility located outside the proposed LCID waste boundary of 12.6 acres or outside the
42-acre landfill property boundary? Please clarify.

ii. If the permittee plans to operate the LCID Processing Facility under the Solid Waste Permit No.
41R-LCID-2011 inside the 42-acre landfill property boundary (as stated in Part 4 of the permit application), please
revise the Section 1.1 and the Facility Plan including, but not limited to:
a. Provide the description of the facility location which must be shown on the facility plan drawing(s) as
2
well.
b. The permit application must provide the stockpile dimensions (the maximum height and size of the lateral extent
must be approved by the Fire Marshall or local fire department), establishment of 25-feet fire isles between
stockpiles, the minimum buffer distance of 25-feet from the stockpile to the on-site drainage features.
c. To avoid speculative accumulation waste, the operation of this facility must meet the requirements
stated in Part 4. Please referring Part 4 in this subsection.

References to the LCID Processing Area, stockpiles, grinding and wood waste recycling and all operational descriptions are a
holdover from previous ownership. All such references have been removed from the application.

5. (Section 1.1) The section describes a portion of the mine site is being reclaimed with “beneficial fill” that meets “Solid
Waste Section definitions”. Please provide additional info of the “beneficial fill:”
i. Define the “beneficial fill” that will be stored at this area, and show the location of beneficial fill
on the facility plan drawing in Part 2 of the permit application.

ii. Demonstrate that operating of this waste management activity will meet the requirement stated in Rule 15A NCAC
13B. .0562(3), and how this fill activity can be differentiated from the disposal of LCID waste activity inside the same
property, if the beneficial fill is inside the LCIDLF waste boundary.

iii. Please describe the size/lateral extents, height, and final grade/side slope of the “beneficial fill” unit.

iv. Provide the info of the maximum volume of the stockpiled beneficial fill that can be stored on- site at any time or
the proposed final fill grade and extents.

v. Describe the erosion and sediment control measures pertaining to operation of this “beneficial fill” area.

This is another holdover from earlier ownership and no longer reflects the current owner’s plans. No beneficial fill will be used for
operations and all references have been removed.

6. (Section 1.1 on Page 2 of the Facility Plan & Section 3.0 of the Operations Plan) Please provide a copy of the NPDES permit
issued by the NC Land Quality Section. An approved site layout drawing must be appended to the permit to show the
proposed 42-acre LCIDLF unit being included by this permit.

The original 42 acres was on both sides of an unnamed tributary that now separates the active mining area to the north from the inactive
area (LCID site) to the south. Although the 42-acre tract was incorporated into a larger property under the mining permit, the permitted
facility boundary for the LCID is still defined by the original facility boundary. The outline of the 42-acres is shown on the drawings,
and a Certificate of Coverage for the current NPDES permit for the mining operations has been added to the application.

7. (Section 2.1) The flood map info of the landfill facility is out-of-date one; please provide the latest (2007) flood map
info of the facility and append the map to the permit application.

The FIRM panel number is current, and newer FIRM publications have not been found. We have included the most recent representation
of the floodplain depicted in Guilford County GIS info.

8. (Sections 2.8) Groundwater potentiometric surface contours underneath this site are shown on the Drawings S3 and S3A, and
the described Drawing S4 can’t be located in the permit application. Please either correct the typo or provide Drawing S4.

Drawing S4 is obsolete and the reference removed from the text.

9. (Section 3.1.5) The property deed document in Appendix 1 is out-of-date. Please provide the current deed document (with
book number and page numbers) which shows that Martin Marietta Materials, Inc. or Martin Marietta Materials Real Estate
Investments, Inc., a subsidiary of Martin Marietta Materials, Inc. owns the 42-acre landfill property.
3
The current deed had been included in the application.

Part 2 – Facility Drawings
10. The note – “Proposed Access Road to Permit 41-12B” should be removed and replaced by Permit 41R- LCID-2011. Since
the LCID Processing Facility and mining activities are operational at the landfill facility, should the road has been built and
functional, rather than a” proposed” one?

The access road in question extends from Viewmont Road (east of the site) toward the center of the mine property. A future extension or
connector across the unnamed tributary is shown in the plans. This part of the road and the stream crossing were permitted earlier by the
Division of Water Quality (401/404) but not constructed. The reference to “proposed” road has been changed to “existing” on the
drawing, but the stream crossing is still labeled “future.” The permit number has been corrected.

11. Please show the 2-acre extents and stockpile locations of the existing LCID Processing Facility on the Facility Plan
drawings.

Please see comment #4 and response. References to stockpile have been removed.

Part 3 Operations Plan (Section 1.2.2) The Winston-Salem Regional Office of the NCDEQ contact info has been changed and can be
found at the web link: http://deq.nc.gov/contact/regional-offices/winston-salem.

Fax: [phone]

The text has been updated.

12. (Section 2.4.1 & Appendix 2) The frequency of the random waste screening (one per month) described in the Section 2.4.1 is
different from that (twice per week) in Appendix 2. To be consistent with the statement in Section 2.4 that “The incoming wastes
received two inspections – at the entrance gate and at the working face…,” Section 2.4.1 should clearly describe that the waste
screening frequency at gate/scale house is once per month, and at the tipping floor for both disposal area and stockpile area will be
twice per week at each area. Please clarify and provide the consistent waste screening frequency.

The text has been updated.

13. (Section 2.5) This section proposes to grind waste at or near LCIDLF working face; several concerns must be properly
addressed:
i. Please explain why the grind waste activities must be conducted at or adjacent to landfill working face, and why
this activity can’t not be conducted at the LCID Processing Facility.
ii. According to the statement in this section, it indicates that a waste sorting/ separating process is likely engaged at/near
the working face of the landfill prior to conducting a waste disposal activity so that the operator(s) can identify and
remove selected waste stream being stockpiled and treated/processed as marketable “recoverable/recyclable” material.
If so,
a. Please describe the operating sequences beginning from the waste screening to
identifying/sorting/recovering waste stream for either grinding or disposing.
b. Descriptions of the waste separating and sorting processes including OSHA health safety,
nuisance prevention, wind-blown waste control measures, and leachate management must be detailed in the
subsection.
c. What “waste stream” will be allowed to be ground at or near the landfill working face?
d. Description of storing the selected waste and ground material stockpiles – locations (must be shown the drawings),
base sizes and heights; the maximum durations – (piles of wastes must be removed and disposed in landfill at the
conclusion of each working day) from at the landfill area; the final stockpile location of the ground material.
e. Provide the minimum distance between the grinding related activity to the landfill disposal activities so that the
grinding activities should not interfere with waste disposal activities.

4
iii. This section proposes “the allowed grinder location shall be constructed as anywhere in the landfill….” The grinder
location may be allowed inside the landfill waste footprint, not anywhere in the landfill, so the buffer requirements for a
treatment and processing unit would be in compliance. Please revise the statement in this section.

Please see comment #4 and response. References to stockpile have been removed.

14. Please state that the unauthorized or nonconformance wastes which are stored in a container should be removed and disposed
of at a permitted landfill at the conclusion of each working day. For any unexpected reason results in the containerized wastes
having to be temporarily stored on-site, the wastes must be covered with a tarp or equivalent material to prevent wastes from
contacting any precipitation.(Section 2.6.5) Please provide the leachate management approaches, should the wastes be
impounded inside water, which is leachate as defined in N.C.G.S. 130A-290(a)(16a), according to Rule 15A NCAC 13B
.0566(14).

This overlaps the earlier permitting of a recycling facility within the LCID (see comment #4). LCID operational permits in the past do
not have provisions for leachate or unacceptable waste removal. These references have been removed.

15. (Section 4.2.3) The Appendix 6 does not provide the contact info. Please list the contact info of the Solid Waste Section
and Regional/Senior Environmental Specialist for the facility area which can be found the following web link:
https://ncdenr.s3.amazonaws.com/s3fs-public/Waste%20Management/DWM/SW/FieldOpMap.pdf

The text is divided into two sections, Facility Plan and Operations Plan, each with its own table of contents. The Solid Waste Section
contact info is found on page 1 of the Operations Plan.

Part 4 – LCID Processing Facility
16. The facility is a treatment and processing unit and LCID storage unit. Therefore, please state the facility is achieved the siting
and operation requirements stipulated in Rule 15NCAC 13B .0301 & .0302. For LCID storage unit, pursuant to Rule 15A
NCAC 13B . 1402(g)(3), please state that the operating the storage unit – either raw final product stockpiles must meet the
requirements stated in Rule 15A NCAC 13B .1404(a)(1) through (9) and also state that NO composting is allowing to be
conducted at this facility.

See comment #13 and response. References to treatment and processing, storage and stockpiles have been removed.

Please provide the written responses to the above-mentioned comments and revised permit application; the submittal of an electronic
copy (in pdf format) of the aforementioned documents is acceptable at this time. The SWS will request a hard copy and an electronic
copy of the final permit application document. Please contact me if you have any question of the comments.

Subject: Viewmont Sandrock LCID Permit 41R-LCID-2011

Greetings, per Ming’s request I am pleased to resubmit the attached permit application. This was prepared and
submitted on October 14, 2016 but it appears to have not been delivered. Please let me know if you need us to
resubmit the paper copy.

By way of explanation, the site was formerly permitted for Viewmont Sandrock in 2010 and reissued for Martin Marietta
in 2011. Please refer to NCDEQ SWS Doc ID 15435. The LCID is proposed as the reclamation stage for an existing borrow
pit, which has not been started as an LCID. The current owner (Martin Marietta) would like to keep the permit active for
future reclamation.

The attached application has been modified from the 2011 application only to reflect my change of employment to
Amec Foster Wheeler and to update the facility and regulatory agency contacts. Otherwise, the application is
unchanged.

Please let me know if you require any further information. Thanks in advance.

RE: Permit Renewal Application
Viewmont Quarry LCID (Permit # 41-R)
Guilford County, North Carolina

Dear Mr. Mussler:

On behalf of Martin Marietta Materials, Inc. (Martin Marietta), Amec Foster Wheeler
Environment & Infrastructure (Amec Foster Wheeler) is submitting this application for a permit
renewal of a planned Land Clearing Inert Debris landfill (LCID). The original permit, prepared
for A-1 Sandrock, Inc. in 2002, served as the reclamation stage of a then-active surface mine for
borrow soil, i.e., a weathered granite saprolite known locally as “Sandrock”.

A-1 Sandrock, Inc. sold the Facility to Viewmont Sandrock, Inc. in late 2003. The Facility was
re-permitted as Viewmont Sandrock in early 2004 and renewed in April 2010 pursuant to an
application prepared by David Garrett & Associates. Martin Marietta bought the property in
2012, and the Facility was permitted under that name shortly thereafter. The property is deeded
to subsidiary Martin Marietta Materials Real Estate Investments, Inc. The mine, and future
landfill, are operated by Martin Marietta Materials, Inc.

To date, the LCID has remained inactive, but the owners wish to keep the permit open for
possible future reclamation activities. This permit renewal application stems from a 5-year
renewal cycle. The various solid waste units and topography are shown on the enclosed
General Facility Map. Please refer to the updated Facility Plan and Operations Plan documents
(enclosed), which have been prepared for electronic submittal in PDF format.

The owners understand that the limits of the LCID footprint addressed in Permit 41-R will be
restricted to permit lines and grades established in 2010, unless further permit amendments are
made. This document was originally submitted to NCDEQ Division of Waste Management,
Solid Waste Section (SWS) in October 2016. This resubmittal includes revisions made in
response to regulatory comments received on March 1, 2017.

PART 1 – FACILITY PLAN

1 GENERAL INFORMATION
1.1 Facility Description
Viewmont Quarry LCID (the Facility) is owned by Martin Marietta Real Estate Investments, Inc.,
(formerly Viewmont Sandrock, Inc.) and is operated by Martin Marietta Materials, Inc. (both are
subsidiaries of Martin Marietta Inc.). The Facility is located south of Greensboro, NC, in Guilford
County, accessible from I-85 Business via the Holden Road or Groometown Road exits and
Bishop Road. The LCID, which remains unbuilt at present, was originally permitted as two
footprints consisting of 12.6 acres to the south of an unnamed tributary and 5.1 acres to the
north of the unnamed tributary (refer to Section 1.2).

The Facility address is 4048 Viewmont Road, Greensboro, NC 27406.

Map coordinates for the original 42-acre tract, which includes the subject LCID site, are
latitude 35.9967 and longitude -79.85505.

Guilford County PIN number for the original 42-acre tract is 12-03-0185-0-0755-S-015
(see Figure 1), and the two adjoining tracts that comprise the 148-acre mine permit
boundary are 12-03-0185-0-0755-S-010 and 12-03-0183-0-0755-N-004.

The Facility is largely surrounded by commercial/industrial sites, with some residences toward
the south. Neighboring facilities include mines and landfills (Doggett and A-1 Sandrock), an
asphalt plant, two trucking terminals, a MSW Transfer Station (Republic Services, Inc.), Guilford
County’s White Goods and Tire Recycling facilities, two closed LCID units, and an auto salvage
yard. The LCID site is not visible from any roads due to natural screening. The nearest known
water wells are more than 900 feet from the LCID disposal unit.

Natural ground elevations vary from El. 820 near center of the Phase 1 footprint to El. 740 at the
tributary along the south property line. Local topography is typically hilly with a wide floodplain
along the unnamed tributary. The local streams serve as the ground water receptors. Drainage
within the LCID footprint is primarily to the north, toward the unnamed tributary, which in turn
flows southeast and joins Hickory Creek near the southern Facility boundary. Plans for the 5.1-
acre footprint to the north of the unnamed tributary were deleted from the application in 2004.

The Facility is located within the General Watershed Area of the Randleman Reservoir. Surface
water removed from the mine is discharged under a NPDES General Permit. The unnamed
tributary joins two other tributaries in the southern portion of the 148-acre tract, forming the head
of Hickory Creek. All of the tributaries are “blue-line” features that originate north of I-85. The
Erosion and Sedimentation Control (E&SC) plan for the entire site is under the jurisdiction of the
North Carolina Department of Energy, Minerals and Land Resources (NCDEMLR), Land Quality
Section. Currently approved E&SC measures are in place for the unbuilt LCID site.

April 14, 2017 Amec Foster Wheeler Project No. 6864166100

Page 3 Facility Plan
The permitted waste stream shall consist entirely of Land Clearing Inert Debris (LCID), typically
stumps, vegetation, soil, rocks, and miscellaneous debris generated by local development. No
Construction and Demolition (C&D) or Municipal Solid Waste (MSW) is accepted at the facility.
No hazardous materials or liquids (including septage) will be accepted. Facility staff is trained to
spot inappropriate wastes and enforce a strict waste acceptance policy. A covered roll-off box
is placed on the premises for unacceptable wastes that may arrive incidentally, i.e., MSW, which
is transported to a licensed disposal facility weekly. Contingency plans are in place for dealing
with hazardous materials.

Daily intake tonnages, once opened, are expected to vary from 75 to 100 tons per day.
Records are kept at the entrance gate on incoming material quantities by truck size and weight.
Typically, the customer base is well known, which provides the facility a high degree of control
over the waste acceptance policy. For this permit renewal, the Facility covers only Phases 1
and 2 on the original 42 acres, as it was issued in 2010 to Viewmont Sandrock (see Figure 2).
Phase 1 covers 5.7 acres and is expected to contain 134,132 cubic yards of total airspace,
while the Phase 2 covers 6.9 acres and will contain 272,328 cubic yards, bringing the total
footprint to 12.6 acres and the total airspace for both phases to 406,460 cubic yards.

1.2 Historical Perspective
The Facility is located on a 42-acre tract that was operated prior to 2002 by A-1 Sandrock, Inc.,
and sold Viewmont Sandrock, Inc. in 2003. An earlier site study following the requirements at
the time for permitting a C&D Landfill was performed for A-1 Sandrock (Appendix 1). The LCID
Permit #41-R was issued to A-1 Sandrock and reissued to Viewmont Sandrock in March 2004.
The 42-acre tract was physically joined to two larger tracts to the east, bringing the mine permit
boundary to 148 acres (Mine Permit #41-23), but for the purposes of the solid waste permit
(#41-R) the facility boundary is limited to the original 42-acre parcel. The area south of the
unnamed tributary (Phases 1 and 2 of the LCID) have not been disturbed since the property
transfer. Active mining is currently taking place on the north side of the unnamed tributary.

1.3 Permit Documents
This document was prepared to meet current Solid Waste Section (SWS) requirements of the
comprehensive Facility Plan and Operations Plan. This plan focuses attention on the waste
acceptance criteria. Facility Plan drawings showing the lines and grades of the approved LCID
accompany this document. At this time, there are no changes proposed.

Operational requirements include maintaining the working face of the disposal area to a
maximum size of one acre. Periodic cover shall be applied at least monthly (or when the
working face exceeds one acre), in accordance with SWS rules for LCID landfills. Personnel
training and regulatory requirements for annual surveys and reporting of data shall be observed.

The landfill will implement “incremental closure” procedures, in which outer slopes that are
brought to final grade will be closed by placing final cover soil and protective measures,
including vegetation and runoff conveyances, in maximum 5-acre increments. A number of
other documents included in the Operations Plan are described as follows.

A Waste Screening Form is presented in Appendix 2 for use in the Waste Screening Program
described in Part 2. A Hazardous Waste Contingency Plan is presented in Part 2, referencing
lists of Emergency Responders in Appendix 3 and Other Useful Contacts in Appendix 4. Due
to concerns over recent fires in other LCID landfills, an upgrade to fire prevention and fire
response procedures is contained in the text, and a Fire Notification Form is presented in
Appendix 5, with which the Operator shall report any fires at the Facility to the SWS. Other
pertinent information includes Updated Title Deed Info presented in Appendix 6 and the current
NPDES Permit presented in Appendix 7. Updated flood mapping is presented in Appendix 8.

2 SITING CRITERIA - .0564 (1) - (10)

Siting requirement demonstrations, described below, are presented in Appendix 1.
2.1 Flood Plain - .0564 (1)
The proposed landfill is not located within a floodplain as defined by the Flood Insurance Rate
Map (FIRM) Panel 370111 0181 C, Guilford County, 2007, please see the map in the link below:
https://msc.fema.gov/portal/search?AddressQuery=guilford%20county#searchresultsanchor.

An excerpt of this map is presented in Appendix 1. The map identifies a floodplain along
Hickory Creek, located several hundred feet east of the site. An unnamed tributary flows
through the proposed landfill site. No solid waste disposal activities will take place within 50 feet
of any stream. Newer floodplain maps are available online from Guilford County Planning.

2.2 Endangered and Threatened Species - .0564 (2)
An environmental assessment report was prepared by a hired consultant, Habitat Assessment
and Restoration Program, Inc., ca. July 2000. Based on that report, presented in Appendix 1,
no endangered plant or animal species have been identified at the site.

2.3 Critical Habitats - .0564 (3)
The environmental assessment report (see above), identified no critical habitats of endangered
plant or animal species on the site. All of the proposed landfill area has been disturbed due to
previous mining activities. The report made no recommendations for further studies.
2.4 Archaeological and Historical Site - .0564 (4)
A letter prepared by the NC Department of Cultural Resources, State Historic Preservation
Office, dated August 24, 2001 (see Appendix 1), indicates no comments on the proposed site
activities relative to properties of architectural, historic, or archaeological significance.

2.5 State Nature and Historic Preserve - .0564 (5)
The site is not located within a State Nature and Historic Preserve area. This is indicated by
letter from the NC Natural Heritage Program, dated July 28, 2000 (See Appendix 1).

2.6 Wetlands - .0564 (6)
The crossing of an unnamed tributary to Hickory Creek has been granted a Nationwide
Wetlands Permit (NWP 14). This work is required to access one side of the tributary from the
other. No other wetlands impacts are anticipated for this project. The NWP 14 Permit is
presented in Appendix 1. Please note: The stream crossing has not been built, and it will be
necessary to renew the NWP-14 permit at a future time prior to the construction.

2.7 Cover Soils - .0564 (7)
Soil for periodic cover will be derived from both on-site and off-site sources. A geotechnical
exploration of the site (Appendix 1) indicates suitable resources of weathered granite, known
locally as “Sandrock,” existing on the north site of the unnamed tributary. Tentatively estimated
soil volume requirements follow:

Periodic cover requires approximately 5% of the estimated volumetric capacity, or

406,460 * 0.05 = 20,323 cubic yards.

Soil cover will be applied monthly, or whenever the working face reaches one acre in size.

Final closure of the proposed LCID will require

12.6 ac. * 43,560 / 27 = 20,328 cubic yards.

The minimum final cover requirements are one foot of soil.

On-site soil resources include the mining operations on the north side of the unnamed tributary.
A summary of testing on these soils is presented on Table 2 and in Appendix 1.

Near surface soils that have limited value as structural fill (for which sandrock is typically
marketed) are available for cover soil, and both the sandrock and overburden soils make

excellent landfill cover material. The Facility accepts soil from various construction sites in the
region, subject to acceptance criteria that no contaminated soils are brought onto the site.

Alternative cover materials, e.g., inert debris, might also be considered as cover material.
2.8 Surface and Ground Water - .0564 (8) (A) - (D)
The proposed landfill will not cause a discharge of pollutants into adjacent surface water bodies
that is in violation of the National Pollutant Discharge Elimination System (NPDES). The facility
will not cause a discharge of dredged material or fill into waters of the State, with the exception
of the proposed stream crossing (see Section 2.6), nor shall the facility constitute a non-point
source of pollution that violates water quality standards. This will be accomplished by observing
appropriate waste acceptance criteria and careful operations.

Since the facility is greater than two acres in size, the minimum 4 feet of separation between the
waste and ground water applies. Ground water observations made by others were modified
with historical data from a nearby monitored facility (see Appendix 1) to determine the
estimated seasonal high water table. Ground water levels at the subject site were compared to
those of the nearby site, also located in a sandrock formation with similar ground surface
topography and proximity to water bodies. Data from monitoring wells with similar
hydrogeologic conditions show water level fluctuations of approximately 3 feet during a period of
record spanning more than 5 years. During that time the region has experienced extremes of
climatic conditions, including very wet weather, i.e. the “El Nino” winter of 1997-98 and various
tropical storms, as well as droughts (see Appendix 1).

A ground water potentiometric surface map, generated from the on-site piezometer
observations (Appendix 1), is presented as Drawing S3 in the accompanying plan set. The
potentiometric surfaces represent the maximum seasonal high water level, estimated by adding
3 feet to highest water levels recorded at each piezometer, based on the historical data. The
proposed grading plan provides the required 4 feet of vertical separation. Excavated grades
should be verified prior to commencing landfill operation.

2.9 Buffer Requirements - .0564 (9)
The layout of the proposed LCID meets the following horizontal buffer requirements: 50 feet
minimum between the proposed waste boundary and all surface waters, including wetlands, and
100 feet to property lines and existing residential dwellings, commercial buildings and wells.
These buffers are clearly marked in the accompanying plan set. The buffers should be field
checked prior to commencing landfill operations.

2.10 Zoning Ordinance - .0564 (10)
The property is zoned HI-SP (heavy industrial with special use), which was put into place for the
mining operations. The Special Use Permit (Appendix 1) acknowledges plans to construct a
future LCID landfill and/or a C&D landfill at the end of mining activities.

3 APPLICATION REQUIREMENTS - .0565 (1) - (4)
3.1 Required Information - .0565 (1)
3.1.1 Local Government Approval - .0565 (1)(a) – A letter from the Guilford County Planning
Department stating that the zoning of the subject property is HI-SP is presented in Appendix 1.

3.1.2 Location - .0565 (1) (b) – The location of the subject site on a county road map is
presented on the cover sheet of the accompanying plan set.

3.1.3 Ground Water Separation - .0565 (1) (c) – Information showing that the proposed
bottom of waste is a minimum of 4 feet above the estimated seasonal high water table is
presented on Drawing E1 in the accompanying plan set. On-site ground water data used to
develop this map are found in Table 3 (see Section 2.8) and Appendix 1.

3.1.4 Rule .0564 Compliance - .0565 (1) (d) – Refer to Section 2 of this report for specific
information pertaining to compliance with this Rule.

3.1.5 Legal Description - .0565 (1) (e) – A legal description of the site is provided with the
title deed in Appendix 1.

3.1.6 Other Information - .0565 (1) (f): Projected Life – The following calculations are based
in part on operational history of an earlier nearby LCID (A-1 Sandrock, Inc.). Since the weight of
the various components of the waste stream vary significantly, it is not feasible to base the life
expectancy calculations on unit weight. Rather, the volume of the waste stream, projected into
months or years, provides a more realistic basis for determining the operational life.

The following daily waste stream projections reflect estimates of waste stream trends. It should
be realized that the waste stream is seasonal and subject to regional economic growth, as well
as market-specific factors, i.e. the potential for other landfills to open or close.

The average daily waste stream projection is:

Concrete 4 tandem-axle trucks per day 10 c.y. each 40 c.y.
Stumps 10 single-axle trucks per day 7 c.y. each 70 c.y.
Bricks 2 single-axle trucks per day 7 c.y. each 14 c.y.
Wood waste 6 single-axle trucks per day 7 c.y. each 42 c.y.
2 tandem-axle trucks per day 10 c.y. each 20 c.y.
Brush 8 tandem-axle trucks per day 10 c.y. each 80 c.y.

Total 32 trucks per day 266 c.y./day

It is assumed that the LCID will operate 5.5 days per week, with 280 working days per year.

The average daily waste stream can be converted to a conservative estimate of in-situ cubic
yards by assuming the size of the trucks delivering the wastes (see table), then assuming an
initial reduction factor of 20% for in-situ compacted volume. Typically, vegetative wastes (brush,

Page 9 Facility Plan
limbs, etc.) are low density and do not initially compact well. Long-term settlement may provide
more actual disposal capacity.

The calculations yield an estimated annual airspace consumption of 74,480 cubic yards. Based
on a net waste disposal capacity of 406,460 cubic yards, the projected operational life of the
facility (two phases) is 5.5 years.
3.2 Aerial Mapping (Quarter-Mile) - .0565 (2)

Page 10 Facility Plan
3.3.6 Water Courses and Wetlands - .0565 (3) (f) and (g) – The only watercourse on the
subject property is the unnamed tributary (Drawing S2). There are wetlands within the tree line,
within the 50-foot stream setback (no disturbance will occur within this area), except for the
permitted road crossing of the stream.

3.3.7 Waste Boundary - .0565 (3) (h) – The waste boundary, which coincides with the 100-
foot property boundary setback, is shown (Drawing S2).

3.3.8 Existing Topography - .0565 (3) (i) – Existing topography is shown (Drawing S2). The
source of the topographic contours within the facility boundary is an aerial survey performed in
March 2001. There have been no changes in the topography within Phases 1 and 2 since the
original permit documents were produced.

3.3.9 Proposed Grading Plan - .0565 (3) (j) – The proposed base grades for Phases 1 and 2
are shown (Drawing E1). The grading plan should be field checked for adequate vertical and
horizontal buffers prior to commencing landfill operation. Fill may be required to restore buffers
in Phase 2. Interior slopes will be at 3H:1V ratios.

3.3.10 Proposed Final Contours - .0565 (3) (j) – Interim final grades are shown for Phase 1
(Drawing E2) and for both Phases 1 and 2 (Drawing E3). Exterior slope ratios will be 3H:1V.

3.4 Operations Plan - .0565 (4)

See Part 2 of this document for the complete Operations Plan - .0566 (1) - (16).

3.4.1 Responsible Parties - .0565 (4) (a) – Refer to the Operations Plan, Section 1.2.1

3.4.2 Projected Land Use - .0565 (4) (b) – Tentative plans for completion of the proposed
LCID are to convert the relatively flatter cap areas (nominal 2% to 5% grades) to
commercial/industrial uses, e.g., parking areas for trucks or equipment and relatively light-
weight prefabricated steel structures. Alternatively, the cap areas might be utilized for stockpile
areas for mulch or other short-term material storage activities. Such post-closure development
will necessitate installation of a thicker than minimum soil cover on the caps to isolate the
wastes. Redevelopment of the side slope areas is not anticipated. Post-closure maintenance
shall be required to ensure proper waste coverage.

Martin Marietta, Inc.

April 14, 2017 Amec Foster Wheeler Project No. 6864166100

Page 11 Facility Plan
3.4.3 Systematic Development and Closure - .0565 (4) (c) – The Operations Plan will
address a scheme for filling and incrementally closing side slopes, beginning in the eastern
portion of the footprint and progressing westward. The main sediment basin (upgrade of an
existing basin) will need to be installed prior to the landfill operations. Existing drainage swales
and basins will be maintained in service as temporary features for as long as possible to spread
out construction costs. The incremental closure of side slopes will proceed whenever an
exterior slope has achieved final grades. Typically, exterior slopes will be closed in one- to two-
acre increments. Vegetation will be established on all slopes as soon as the soil cover has
been placed. The final closure will meet the regulatory minimum cover thickness requirement
(12 inches). At some future time, the final cover plan may be modified to accommodate post-
closure site development plans.

3.4.4 Waste Characterization - .0565 (4) (d) – The LCID shall only accept permitted waste
streams, tentatively identified as land clearing wastes, inert debris (non-contaminated soil, rock,
concrete, brick, block, other rubble), untreated wood, and yard wastes. No liquid or hazardous
wastes will be accepted, nor will household garbage be disposed on-site.

3.4.5 Emergency Contingency Plan - .0565 (4) (e) – The primary emergency of concern,
relative to landfill operations, involves fire and rescue. The Pinecroft-Sedgefield Fire
Department, located at 2239 Bishop Road, is available for fighting fires. Stockpiles of soil shall
be kept on-hand for fighting fires that might involve the waste. The mining operations on the
premises have exhibited a good operational record with no documented fires. Section 3 of the
Operations Plan presents a detailed contingency plan for inclement weather and other
emergencies.

Page 2 Operations Plan
1.4 Fire and Safety
1.4.1 Fire Prevention – Fires within LCID landfills are a concern to the Solid Waste Section,
due in part to health and safety issues for customers, staff and the neighbors, in addition to
long-term air and water quality issues. The effort required to fight a major facility fire is costly
and disruptive to operations.

The Operator shall be vigilant about preventing fires and keeping access and resources
available to fight fires. Portable fire extinguishers should be kept in all Facility vehicles and
within the buildings. A combination of factory installed fire suppression systems and/or portable
fire extinguishers shall be inspected periodically and kept operational on all heavy equipment.

Fires within the landfill will be limited by the use of periodic cover soil and control of "hot" loads
entering the landfill. An ample supply of soil shall be kept available for smothering a small fire,
observing proper measures for erosion control. Access to undeveloped portions of the footprint
(additional soil resources) shall be kept free of unnecessary debris.

A daily “ride-through” shall be conducted to look for smoke – steam does not necessarily mean
a fire is present, but continual steaming should be monitored and, if present, vents should be
checked periodically for signs of charring or detectable heat.

1.4.2 Fire Control – If a fire breaks out, the Operator should take immediate steps to prevent
harm to employees and customers. Small fires may be extinguished using on-site resources, if
it is safe to do so. If the waste catches fire, efforts will be made to extinguish the fire by
smothering it with dirt. Water is the least desirable means of fighting a landfill fire, but placing
water on a small fire is acceptable. For larger or more serious outbreaks, the local fire
department should be contacted by calling “911”.

Additional guidance for response to a fire is provided in the Contingency Plan (Section 3.0). All
fires should be reported immediately to the Area Solid Waste Specialist. A Fire Notification
Form (Appendix 5) must be completed and submitted to the SWS within 24 hours.

1.4.3 Safety – All aspects of landfill operation should be conducted with the health and safety
of the operating staff, customers, and neighbors in mind. A member of the staff should be
designated as Site Safety Officer (SSO), who should undergo safety training in addition to a
landfill operator’s training course. The SSO, together with the facility's management, will
administer a comprehensive site safety and emergency response program to be consistent with
Occupational Safety and Health Administration (OSHA) guidance.

Safety equipment to be provided includes equipment rollover protective cabs, seat belts, audible
reverse warning devices, hard hats, safety shoes, and first aid kits. Landfill personnel will be
encouraged to complete the American Red Cross Basic First Aid Course. Hazards should be
identified and communicated to personnel, such as the danger of operating equipment or
vehicles on or near relatively steep slopes. Specific hazards may require mitigation, such as
placing warning signs or barricades next to slopes where traffic is present.

Page 3 Operations Plan
1.5 Equipment Requirements
The facility will maintain on-site equipment as required to perform the necessary landfill
activities. Faulty equipment that constitutes a safety issue or jeopardizes the ability to operate
the facility in compliance with applicable rules shall be repaired or replaced. Periodic
maintenance of equipment and routine repair work will be performed at designated maintenance
zones outside of the landfill. Emergency maintenance on broken down equipment that must
occur within the disposal area should be monitored and/or protected with appropriate measures
to prevent spills or leaks that could become water quality issues. Equipment and vehicle fueling
shall be conducted to avoid spills.

1.6 Utilities
Electrical power, water, telephone, and sanitary facilities will be provided at the gatehouse.

1.7 Record Keeping Program
The Landfill staff shall maintain the following records related to the LCID landfill in a permanent
operating record at the landfill:

A Waste inspection records;
B Daily intake records, including waste type and source;
C List of generators and haulers that have attempted to dispose of restricted
wastes;
D Employee training procedures and records of training completed;
E All closure and post-closure information, where applicable, including:
1. Testing;
2. Certification; and
3. Completion records.
F Cost estimates for financial assurance documentation.

The operating record shall be kept up to date by the Owner or his designee. These records
shall be presented upon request to SWS for inspection. A copy of this Operations Manual shall
be kept at the gatehouse and be available all times. All staff should be familiar with this
manual.

1.8 Height Monitoring
The landfill staff will monitor landfill top and side slope elevations on a weekly basis. This shall
be accomplished by use of a surveyor’s level and a grade rod or other surveying methods.
When such elevations approach the grades shown on the Final Cover Grading Plan, the final
top-of-waste grades will be staked by a licensed surveyor to limit over-placement of waste. An
annual survey of the landfill shall be performed to confirm that lines and grades are within the
specified requirements and to facilitate a volumetric analysis of the airspace.

2 WASTE HANDLING AND DISPOSAL - .0566 (2)

2.1 Acceptable Wastes
The LCID disposal facility shall only accept the following wastes:

• Land Clearing and Inert Debris Waste (yard waste, stumps, trees, limbs, brush,
grass, concrete, brick, concrete block, uncontaminated soils and rock, untreated
and unpainted wood, etc.).

• Other Wastes as Approved by the NCDEQ Solid Waste Section.

2.2 Prohibited Wastes
No municipal solid waste (MSW), hazardous waste as defined by 15A NCAC 13A .0106, which
can be viewed at the Division of Waste Management web site: www.wastenotnc.org, including
hazardous waste from conditionally exempt small quantity generators, or liquid waste will be
accepted at this facility. No polychlorinated biphenyl (PCB) waste will be accepted. No
asbestos containing materials (ASM) or naturally occurring radioactive materials (NORM) will be
accepted. No septage or putrescible materials will be accepted. Animal carcasses will not be
accepted. Shingles will not be accepted except as incidental debris. The Owner will implement a
waste screening program, described in Section 2.3, to control these types of waste.

2.3 Waste Screening Program
In order to assure that prohibited wastes are not entering the facility, waste screening programs
must been implemented. The incoming wastes are subject to screening inspections at the
entrance gate and at the working face of the disposal area. Procedures for conducting the
waste inspections are described briefly below. Detailed guidance on waste identification and
the Waste Screening Form are located in Appendix 2.

2.3.1 Waste Receiving and Inspection – All vehicles must stop at the entrance gate. The
attendant shall question each driver about the nature and source of the incoming materials and
record the load. The gate attendant(s) may visually check the load if the vehicle or driver is
unfamiliar. If visually inspecting the load does not provide a sufficient indication of its contents,
or if the attendant becomes suspicious of a load, the vehicle should be directed to a designated
unloading area (not on the working face) for detailed inspection. Vehicles shall be selected for
random screening by the gate attendant at a minimum of once per month.

The attendant shall alert the yard operators via radio with information on the incoming load, e.g.,
material type, truck description. Each incoming vehicle shall be unloaded at the direction of a
Field Superintendent or a designee. These individuals should have specific training to
recognize hazardous or otherwise banned materials. The Superintendent or designee shall be
present when each vehicle is unloaded to make sure the material is acceptable. Vehicles shall
be selected by the Superintendent for random screening at the designated unloading area a
minimum of twice per week. All screening activities shall be recorded on the appropriate form.

April 14, 2017 Amec Foster Wheeler Project No. 6864166100

Page 5 Operations Plan
2.3.2 Waste Load Rejection – If the screening identifies no banned materials, the waste load
may be incorporated into the working face. If unacceptable materials are found during the
random screenings, or at any other time, those materials shall not be allowed to enter the
working face and one of several options shall be implemented. The offending materials may be
isolated from the remainder of the load and placed into a suitable container, e.g., a roll-off box,
for off-site disposal. The whole load might be rejected and transferred to a suitable container or
reloaded into the delivery vehicle.

The driver and/or owner of the vehicle might be compelled to remove the unacceptable
materials. Ideally, unacceptable materials will be detected prior to unloading, or they will be
reloaded onto the delivery vehicle and sent away (with directions to an appropriate facility). Any
attempts to unload unacceptable materials at the Facility shall be documented by the operator.
Repeat offenders may be banned from using the landfill, or law enforcement may be notified.

2.3.3 Hazardous Materials – If at any time material with strong odors, fumes, vapors, liquids,
unusual colors or appearance, smoke, flame, or excess dust are detected, all operations shall
be suspended and non-essential personnel cleared from the facility. Refer to Section 3.3.

2.4 Disposal Operations
2.4.1 Access – The location of access roads and staging areas near the working face will be
directed by the Field Superintendent to maintain a safe and orderly waste placement strategy.
The use of portable signs with directional arrows and portable traffic barricades along the
access route to the working face will facilitate the unloading of wastes at proper locations. The
Superintendent or the designee must be able to observe all unloading of waste.

2.4.2 Waste Placement - .0566(3) – On the working face, equipment operators shall observe
the unloaded materials as they move the materials into the active disposal area. This provides
another opportunity to detect inappropriate materials before they are incorporated into the
landfill. All activities shall emphasize safety for the workers and customers.

The waste shall be placed into the smallest area as feasible and compacted as densely as
practical. Typically, the wastes should be spread out into 2 foot lifts and compacted on
relatively flat slopes (i.e., 5H:1V max.) using a minimum number of three full passes. A
maximum slope ratio of 3H:1V shall be observed at all times. The working face should be
kept under an acre, unless provisions are made for placing periodic cover soil.

2.4.3 Periodic Soil Cover - .0566 (4) – At the completion of waste placement on a monthly
basis or sooner if the working face exceeds one acre in size, a 6 inch layer of earthen material
will be placed over the exposed waste. This periodic cover is intended to control vectors, fire,
odors, and blowing debris. Alternative periodic covers are allowable with the prior approval of
the SWS. Voids should be completely filled and no waste should be visible at the surface.

2.5 Incremental Final Cover - .0566 (5)
Soil cover shall be applied at a minimum thickness of 12 inches within 120 calendar days to any
completed stage of the landfill. This includes side slopes or areas that will become inactive and
not receive additional waste for a period exceeding 120 days. The soil cover should be sloped
Martin Marietta, Inc.
Viewmont Road LCID Permit 41R-LCID Renewal
April 14, 2017 Amec Foster Wheeler Project No. 6864166100

Page 6 Operations Plan
to promote positive drainage. Except for final exterior slopes, the soil cover may be stripped
down to a thickness of 6 inches before placing additional waste. The planned construction
sequence includes building final slopes to grade and applying vegetated final cover in
approximately one-acre increments.

2.6 Erosion and Sedimentation Control - .0566 (6)
An erosion and sedimentation control (E&SC) plan was provided with the original Permit
Application for this facility. That submittal was reviewed and approved by the NCDEMLR Land
Quality Section and remains in force. The plan describes the engineered features and practices
for preventing erosion and controlling sedimentation at this site. The erosion and sediment
control system consists of the following components:

1. Diversion Berms/Benches
2. Ditches
3. Down channels
4. Sediment Basin.

The landfill side slopes are designed with 3H:1V slopes and diversion berms or benches placed
at slope breaks and at approximately 30-foot vertical intervals. These features are designed to
keep water volumes and velocities low enough to minimize erosion of the landfill cover.
Maintenance of the cover system will involve periodic mowing and repair of any erosion
problems and bare spots. These features will be inspected at least once a month and after any
significant rainfall events.

The down channels are designed to carry concentrated flows of surface water from the landfill
surface. The down channels will be inspected at least once a month and after any significant
rainfall event. Additional erosion control measures have been taken within the drainage
channels and at points of storm water discharge. All final cover areas should be inspected
regularly for erosion damage and promptly repaired.

Storm water run-off from the LCID landfill Facility is conveyed to the existing sedimentation
basin(s) located outside the disposal area footprint. The basin(s) should be inspected regularly
for sediment build-up or erosion damage. The basin(s) should be cleaned out by excavating
when sediments fill the lower half of the basin.

2.7 Vegetative Cover - .0566 (7)
Ground cover shall be established within 20 days following completion of any phase of landfill
development. Temporary mulch may be used in accordance with the E&SC plan.

2.8 Security - .0566 (8)
2.8.1 Physical Restraints – The site is accessible only by the main entrance along Viewmont
Road. An attended scale house is located near the main entrance. Other potential access
points are blocked by gates or barricades, and the rest of the site is isolated from the public by
dense vegetation and/or steep topography.

Martin Marietta, Inc.
Viewmont Road LCID Permit 41R-LCID Renewal
April 14, 2017 Amec Foster Wheeler Project No. 6864166100

Page 7 Operations Plan
Access to the Facility will only be allowed when the attendant is on duty. Gates will be securely
locked during non-operating hours. Frequent inspections of gates and fences will be performed
by the staff. Evidence of trespassing, vandalism, or illegal disposal will be reported to the
Owner, who will take appropriate steps to minimize such access.

2.8.2 All-Weather Access- .0566 (9) – The main entrance road and interior roads shall be
maintained to allow access during inclement weather for emergencies (such as fighting a fire).

2.9 Environmental Management

2.9.1 Surface Water Diversion - .0566 (10) – Storm runoff from uphill areas shall be diverted
away from the working face, and any areas where waste fill has occurred, via the use of ditches
and/or soil berms. Such measures may be temporary or permanent in nature. Water shall not
be allowed to run against or impound upon the waste.

2.9.2 Standing Water Prohibition - .0566 (11) – No waste shall be placed in open water
bodies. Adequate drainage shall be maintained to promote positive drainage away from waste
disposal areas. If water is impounded, it shall be removed prior to placing waste material.

2.9.3 Open Burning Prohibition - .0566 (12) – No open burning of solid waste shall be
allowed.

2.9.4 Landfill Gas Control - .0566 (13) – Due to the nature of the waste disposed in this
landfill, landfill gas control is not anticipated to be of concern. No methane monitoring is
currently prescribed for this facility. However, future Solid Waste Rule changes might require
that a monitoring plan for methane be incorporated into this Operations Plan.

2.9.5 Vector Control – Due to the nature of the waste disposed in this landfill, vector control
will not be of concern. Note that the use of periodic cover will discourage animals from nesting
in the waste.

2.9.6 Odor Control – Due to the nature of the waste disposed in this landfill, odor control is
not typically of concern.

2.9.7 Dust Control – Dust related to traffic on the access roads will be minimized by using a
water truck. Dust generated by excavation of cover soil will be limited by watering the cut areas
as needed. Staff should avoid breathing in dust generated by the waste itself. Steps to
minimize fugitive emissions, e.g., wind breaks or sprinkling water, shall be taken on windy days.

2.10 Best Management Practices - .0566 (14)
Water that contacts solid waste is defined as “leachate”. For LCID wastes, the runoff is
managed as storm water through conventional erosion and sedimentation control (E&SC)
measures or, in cases where discharges to nutrient sensitive surface waters may be detrimental
to water quality, additional measures may be required to meet applicable water quality
standards. The LCID disposal unit has not been built and, thus, no additional measures or
monitoring is anticipated to be required at this time.
Martin Marietta, Inc.
Viewmont Road LCID Permit 41R-LCID Renewal
April 14, 2017 Amec Foster Wheeler Project No. 6864166100

Page 8 Operations Plan
2.11 Ground Water Monitoring - .0566 (15)
At present, ground water monitoring is not required at LCID facilities. As such, no ground water
wells or monitoring has been anticipated or included in this application. Should future
regulations so warrant, a ground water monitoring plan will be prepared in accordance with
SWS requirements, and the facility shall submit a future revision of this Operations Plan.

2.12 Signage - .0566 (16)
A prominent sign containing the information required by SWS will be placed just inside the main
gate. This sign will provide the name of the facility, the permit number, operating hours,
acceptable and prohibited wastes, and emergency contact information. Additional signage will
be provided within the facility to distinguish the roadway to the active disposal area. Service
and maintenance roads will be clearly marked, and barriers (e.g., traffic cones, barrels, etc.) will
be provided as required.

3 CONTINGENCY PLAN
3.1 Hazardous Waste
Hazardous materials may arrive at the landfill due to a nefarious attempt at illegal disposal, or,
more likely, these materials might be unintentionally mixed into a load or waste. Some wastes
that are considered as hazardous or otherwise prohibited from the facility – even those that do
not constitute an emergency – may require special handling by licensed contractors. If
hazardous materials are detected during random screening or at any time during operations,
this Hazardous Waste Contingency Plan will be implemented.

Identification – Hazardous materials might be identified by unusual appearances, colors,
odors, fumes, liquids escaping or the materials may be hot or burning. There may be warning
labels on containers or unusual packaging. The staff should be suspicious of any materials that
arrive in drums or black bags that prevent direct observation of the materials. In the event that
identifiable hazardous waste or waste of questionable character is detected, protection of
personnel shall take precedence.

Responsibility – The Facility Manager should assess the situation and take appropriate steps
to protect on-site personnel (primary) and the environment (secondary). The response should
be commensurate with the nature of the incident. For most conceivable incidents, calling “911”
followed by removal of the material is sufficient, but emergencies that constitute a threat to
human health or the environment must also be anticipated.

Contacts – Emergency responders may come from one of many organizations, i.e., local Fire
Department or Haz-Mat Team has the expertise to safeguard the public and direct response
activities. Typically, those entities arrive with a Scene Commander who shall take charge.
Landfill staff shall follow the Scene Commander’s directions to assist or stay out of the way.

In the event no Scene Commander is present, the Facility Manager, Field Superintendent or a
designated member shall assume the role of responsibility and contact the appropriate
authorities, depending on the nature of the emergency.

Martin Marietta, Inc.
Viewmont Road LCID Permit 41R-LCID Renewal
April 14, 2017 Amec Foster Wheeler Project No. 6864166100

Page 9 Operations Plan
A list of potential responders, such as clean-up firms and disposal facilities, is presented in
Appendix 3. A list of government agency contacts is presented in Appendix 4, but the first
contact should be “911” for life threatening situations, followed by contacting the Solid Waste
Section specialist for all potential compliance issues. The onus is upon the Owner/Operator to
make sure the staff knows how to respond to an emergency – before it happens.

Facility Response – If hazardous materials are identified, these materials shall be prohibited
from being unloaded, if possible, and the driver of the delivery vehicle made aware of options for
legal disposal (see Appendices 3 and 4). If hazardous materials are detected prior to
unloading, the delivery vehicle shall be isolated and appropriate emergency response personnel
called in. The Operator will notify the Solid Waste Section that an attempt was made to dispose
of hazardous waste at the facility.

If the vehicle has been unloaded, Operations shall be suspended and the affected area shall be
cleared of personnel until qualified response personnel arrive. If safe to do so, the area should
be isolated by blocking the nearest runoff conveyances (with soil) to prevent contaminated
runoff from entering the stormwater basin. No attempt will be made to remove the material until
trained emergency personnel (fire department or haz-mat team) arrive.

If the driver of a vehicle attempting to dispose (or having had disposed) of such waste is
uncooperative, the vehicle should be prevented from leaving the site until it is identified (license
tag, truck number driver and/or company information). If the vehicle leaves the site, the
Operator shall notify law enforcement and the owner of the vehicle should be contacted.

Hot Loads – If a “hot load” enters the facility, this is treated as a fire. The vehicle will be
directed to an isolated and unloaded immediately (if safe to do so), then the vehicle and driver
shall be moved to safety and the fire department shall be called.

Record Keeping – All hazardous material incidents require notification of the Solid Waste
Section (see Section 1.2.2). The incident shall be documented using the Waste Screening
Form provided in Appendix 2 and placing the completed form in the Operational Record.
3.2 Severe Weather
Severe weather events can directly affect the operation of the facility. Some typical weather
related conditions and recommended operational responses are as follows.

3.1.1 Ice Storms – An ice storm can hinder access and prevent safe movement of equipment.
Closure of the landfill may be required until the ice is melted or removed.

3.1.2 Heavy Rains – Exposed soil surfaces when wet can hinder equipment mobility and pose
a safety hazard. Proper drainage control and the use of aggregate on unpaved roads should be
observed to provide all-weather access and to control runoff. If an aggregate surface is eroded
or damaged, repairs should be made as soon as possible. Intense rains can erode newly
constructed drainage measures, e.g., channels, diversion berms, and cover soils. These
surfaces should be protected with ground cover. Following a significant rain event, i.e., one-half
inch or more, the staff should inspect the measures and make repairs prior to the next rainfall.

3.1.3 Electrical Storms – The open areas of the facility are susceptible to the hazards of an
electrical storm. If necessary, facility activities will cease during such an event, and refuge
Martin Marietta, Inc.
Viewmont Road LCID Permit 41R-LCID Renewal
April 14, 2017 Amec Foster Wheeler Project No. 6864166100

Page 10 Operations Plan
should be taken within buildings or in rubber-tire vehicles. Personnel should avoid metal
objects, open spaces, and water bodies during such events.

3.1.4 Windy Conditions – Blowing debris can constitute safety hazards and/or environmental
concerns. Normally, this authorized waste stream should not be susceptible to light wind, but
high winds could blow smaller debris. Daily operations should minimize exposure to prevailing
winds – operations should be sheltered by locating activities on the lee-side of slopes and other
natural wind barriers. The work area may need to be shifted to a more sheltered area.

3.1.5 Violent Storms – In the event of a hurricane, tornado, or severe winter storm warning,
facility operations should temporarily cease until the warning is lifted. If there is adequate time,
soil cover should be placed on exposed waste. If there is eminent danger to staff, personal
safety shall take precedence over concerns regarding the waste or equipment. The operation
staff should monitor appropriate media for severe weather alerts.

3.3 Fire in the Facility
The waste may compost under normal circumstances and attain sufficient temperatures to
combust. Early signs of fires in the LCID may be smoke or charring observed at “vents” (cracks
in the surface). It is normal to see steam rising from the waste, especially on cold mornings –
this does not necessarily indicate a fire, but areas of frequent steaming should be watched
closely. In the event of an actual fire, steps should be taken to safeguard site workers and the
public, notifying the fire department and the Solid Waste Section specialist.

3.2.1 Minor Fires – The possibility of a brush fire or a piece of equipment must be anticipated.
A combination of factory installed fire suppression systems and/or portable fire extinguishers
shall be operational on all heavy pieces of equipment at all times. Spreading dirt or using water
on a small surface fire is effective. For larger or more serious outbreaks, call the local fire
department.

3.2.2 Hot Loads – The gate attendant shall prevent vehicles containing waste that is
suspected to be hot, e.g., smoldering or smoking. If a "hot" load is detected at the entrance
gate, the driver shall be directed to an isolated location away from the public (but accessible to
firefighting equipment). The driver shall dump the load on the ground and move the truck to a
safe location – emphasis shall first be placed on the driver and staff’s safety, and then the truck,
if safe enough to do so. If a hot load is placed on the working face, then the load will be spread
as thin as possible and cover soil will be immediately placed on the waste to extinguish the fire.
The working face shall be closely monitored for fires.

3.2.3 Major Fires – If the waste catches fire, efforts will be made to extinguish the fire before it
grows out of control. The most effective means of combating a fire in the waste is to carefully
excavate the fire and smother it with dirt. Stockpiles of dirt should be kept on hand during the
operational phases. Water is the least desirable means of fighting a large landfill fire. The
application of water has not proven to be an effective means of extinguishing deep fires in LCID
landfills, and runoff water from a landfill fire will become a water quality issue. All fires should
be reported to the Solid Waste Section Area Specialist (see Appendix 5).

PART I – INTRODUCTION

SECTION A: GENERAL PERMIT COVERAGE

All persons desiring to have facilities covered by this General Permit must register with the Division
of Energy, Mineral, and Land Resources (DEMLR) by the filing of a Notice of Intent (NOI) and
applicable fees. The NOI shall be submitted and a certificate of coverage issued prior to any
discharge of stormwater associated with industrial activity, mine dewatering wastewater, or
authorized process wastewater that has a point source discharge to the surface waters of the state.

This General Permit is applicable to mining and quarrying of nonmetallic minerals (except fuels)
including borrow pits (that would not be covered under the statewide DOT stormwater permit) and
active or inactive mines that discharge stormwater contaminated with, or that has come in contact
with, any overburden, raw material, intermediate products, finished products, byproducts or waste
products located at the site of such operations and stormwater runoff from vehicle maintenance
areas. This General Permit also covers discharge of wastewater from processing mined materials
and mine dewatering wastewater from the groundwater and/or stormwater that accumulates in
the mine pit.

Any owner or operator not wishing to be covered or limited by this General Permit may make
application for an individual NPDES permit in accordance with NPDES procedures in 15A NCAC 2H
.0100, stating the reasons supporting the request. Any application for an individual permit should
be made at least 180 days prior to commencement of discharge.

This General Permit does not cover activities or discharges covered by an individual NPDES permit
until the individual permit has expired or has been revoked. Any person conducting an activity
covered by an individual permit but which could be covered by this General Permit may request
that the individual permit be revoked and coverage under this General Permit be provided.

Any facility may apply for new or continued coverage under this permit until a Total Maximum
Daily Load (TMDL) for pollutants for stormwater or wastewater discharges is established. A TMDL
sets a pollutant-loading limit that affects a watershed, or portion of a watershed, draining to an
impaired water. For discharges to watersheds affected by a TMDL, coverage under this
permit may depend on the facility demonstrating it does not have reasonable potential to
violate applicable water quality standards for those pollutants as a result of discharges. If
the Division determines that discharges have reasonable potential to cause water quality standard
violations, the facility shall apply for an individual permit 180 days prior to the expiration date of
this General Permit. Once that individual permit is effective, the facility will no longer have
coverage under this General Permit. [Note the permittee must identify impaired waters (scheduled
for TMDL development) and waters already subject to a TMDL in the Location Map or Site Map, as
outlined in the Stormwater Pollution Prevention Plan (SPPP), Part III. A list of approved TMDLs for
the state of North Carolina can be found at http://portal.ncdenr.org/web/wq/ps/mtu/tmdl.]

Permit No. NCG020000

Parts I-II Page 2 of 3
SECTION B: PERMITTED ACTIVITIES

Until this permit expires or is modified or revoked, the permittee is authorized to discharge
stormwater, mine dewatering, and process wastewater to the surface waters of North Carolina or a
separate storm sewer system which has been treated and managed in accordance with the terms
and conditions of this General Permit and the requirements of the permittee’s Certificate of
Coverage (COC).

The permittee’s COC is hereby incorporated by reference into this General Permit. Any
violation of the COC is a violation of this General Permit and subject to enforcement action as
provided in the General Permit.

Any other point source discharge to surface waters of the state is prohibited unless it is an
allowable non-stormwater discharge or is covered by another permit, authorization, or approval.
The discharges allowed by this General Permit shall not cause or contribute to violations of
Water Quality Standards. Discharges allowed by this permit must meet applicable wetland
standards as outlined in 15A NCAC 2B .0230 and .0231 and water quality certification requirements
as outlined in 15A NCAC 2H .0500.

If mining activities will expand or change such that the types of discharges are affected, the
permittee must first contact DEMLR’s Stormwater Permitting Program to determine if
modifications to the COC are necessary. The permittee is also responsible for contacting DEMLR if
modifications to the Mining Permit are necessary, as compliance with the Mining Permit is a
stipulation of this permit.

This permit does not relieve the permittee’s responsibility for compliance with any other applicable
federal, state or local law, rule, standard, ordinance, order or decree.

Parts I-II Page 3 of 3
PART II –OPERATION OF A TREATMENT FACILITY

Mining operations involving construction and operation of existing, new, and expanding
wastewater treatment facilities for mine dewatering or process wastewater (such as saw water,
wash water, etc.) shall be subject to the following operational requirements.

1. Operation and maintenance of treatment facilities must be in accordance with the
requirements in this General Permit. For the purposes of this permit no documentation
other than a signed Certificate of Coverage (COC) is required to operate a treatment facility.

2. Diversion or bypass of untreated wastewater from a treatment facility is prohibited except
under provisions of this permit in Part V, Section C.4 and Part V, Section E.8.

3. In the event that a facility fails to perform satisfactorily, including the creation of nuisance
conditions, the permittee shall take immediate corrective action, including those actions
that may be required by the North Carolina Department of Environmental Quality (NC DEQ,
formerly NC DENR), such as the construction of additional or replacement treatment or
disposal facilities.

4. The issuance of this permit shall not relieve the permittee of the responsibility for damages
to surface waters of the State resulting from the operation of a treatment facility.

5. Any discharge from a treatment system to groundwater must protect the groundwater
standards specified in 15A NCAC 2L, Groundwater Classification and Standards.

6. Any groundwater quality monitoring, as deemed reasonably necessary by NC DEQ, shall be
provided.

7. Flocculants evaluated by NC DEQ may be used if administered in accordance with maximum
application doses and any other current requirements. No other chemical flocculants shall
be used in the treatment facility without written authorization from the Division. Evaluated
Polyacrylamide (PAMS) information can be found on the Stormwater Permitting Program
website.

8. All discharges of mine dewatering wastewater and process wastewater will be monitored in
accordance with Part IV, Section D of this permit.

Permit No. NCG020000

Part III Page 1 of 5
PART III – STORMWATER POLLUTION AND PREVENTION PLAN (SPPP)

The permittee shall develop and implement a Stormwater Pollution Prevention Plan (SPPP). The
SPPP shall be maintained on site unless exempted from this requirement by the Division. The SPPP
shall be considered public information in accordance with Part V, Standard Conditions for NPDES
General Permits, Section E, Paragraph 3 of this General Permit. The SPPP shall include, at a
minimum, the following items:

1. Site Overview. The Site Overview shall provide a description of the physical facility and the
potential pollutant sources that may be expected to contribute to contamination of
stormwater discharges. The Site Overview shall contain the following:

(a) A general location map (USGS quadrangle map or appropriately drafted equivalent
map), showing the facility's location in relation to transportation routes and surface
waters; the name of the receiving water(s) to which the stormwater outfall(s)
discharges, or if the discharge is to a municipal separate storm sewer system, the
name of the municipality and the ultimate receiving waters; and latitude and
longitude of the point(s) of stormwater discharge associated with industrial activity.
The general location map (or alternatively the site map) shall identify whether each
receiving water is impaired (on the state’s 303(d) list of impaired waters) or if the
site is located in a watershed for which a TMDL has been established, and what
the parameter(s) of concern are.

(b) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices. A narrative description of the potential pollutants that
could be expected to be present in the stormwater discharge from each outfall.

(c) A site map drawn at a scale sufficient to clearly depict: the site property boundary;
the stormwater discharge outfalls and wastewater discharge outfalls; all on-site and
adjacent surface waters and wetlands; industrial activity areas (including storage of
materials, disposal areas, process areas, loading and unloading areas, and haul
roads); site topography; all drainage features and structures; drainage area
boundaries and total contributing area for each outfall; direction of flow in each
drainage area; industrial activities occurring in each drainage area; buildings;
stormwater Best Management Practices (BMPs) with design capacities; and
permanent impervious surfaces, such as roads or process areas that are unlikely to
change frequently. The site map shall include a graphic scale indication and north
arrow. In addition, the following industrial activity areas must also be identified on
the site map: fueling, vehicle maintenance and repair, washing of materials or
equipment.

(d) A list of significant spills or leaks of pollutants that have occurred during the
previous three (3) years and any corrective actions taken to mitigate spill impacts.

(e) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The permittee shall re-certify annually that the
stormwater outfalls have been evaluated for the presence of non-stormwater
discharges. If non-stormwater discharges are present, the permittee shall identify the
source and record whether the discharge is otherwise permitted (by rule or a different
permit). The permittee shall evaluate the environmental significance of the non-
stormwater discharges and include a summary written record with the certification.
Permit No. NCG020000

Part III Page 2 of 5
The certification statement and summary written record shall be retained with the
SPPP, and shall be dated and signed in accordance with the requirements found in
Part V, Standard Conditions for NPDES General Permits, Section B, Paragraph 5.

2. Erosion and Sedimentation Control. The permittee shall implement the management
practices and the erosion and sedimentation control measures that are included in the
mining permit or erosion and sedimentation control permit issued by the Division of
Energy, Mineral, and Land Resources (DEMLR). Compliance with the DEMLR issued
Mining Permit is considered a requirement of this General Permit. Any deviation from
the Mining Permit and/or Erosion and Sedimentation Control Permit, or amendments to the
issued permit, that impacts water quality shall constitute a violation of the terms and
conditions of this General Permit. All erosion and sediment controls shall be inspected, and
a respective written record of repairs and maintenance shall be available to DEMLR
inspectors. A signed copy of the issued Mining Permit, including the approved erosion
and sedimentation control measures and the reclamation plan, shall be maintained
on the site at all times. Once an area is released by DEMLR in accordance with NC G.S.
Chapter 74, Article 7, it shall no longer be subject to this General Permit.

3. Stormwater Management Strategy. The Stormwater Management Strategy shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater and the transport of
significant materials by stormwater, including structural and nonstructural measures. The
Stormwater Management Strategy, at a minimum, shall incorporate the following:

(a) Management of Stormwater Runoff and Runon. The permittee shall maintain
stormwater BMPs for mine excavation and disturbance areas, process areas, and
any other areas associated with mining or vehicle maintenance activities. In
addition, controls should be used to limit or isolate selected land disturbance and
process areas and limit the amount of off-site stormwater runon to those areas.
Appropriate Best Management Practices (BMPs) should be used to divert, infiltrate,
reuse or otherwise manage stormwater runoff and runon in a manner that reduces
pollutants in stormwater discharges leaving the site. Appropriate BMPs may
include but are not limited to: vegetative swales, berms, use of reclaimed mine
areas, and reuse of collected stormwater (such as for an industrial process or as an
irrigation source).

(b) BMP Controls Inspection and Maintenance. BMPs shall be inspected by or under
the direction of the permittee at least once every seven calendar days, unless the
site is inactive. All inspections and BMP repairs shall be documented by written
record.

Reduced BMP Inspections for inactive mines: Dormant Site Status is available for
inactive mines that have suspended all industrial activities, and if the permittee
has certified to DEMLR’s Stormwater Permitting Program that all portions of the site
where clearing, grading, and/or excavation activities have occurred have been
stabilized with vegetation. Under dormant status the permittee may conduct BMP
inspections once a month. The permittee shall send written certification to the
DEMLR Regional Office that the site is inactive, and the Regional Office may grant
reduced BMP inspection frequency on the basis of the permittee’s certification. The
permitted site may be subject to an inspection for verification. The DEMLR Regional
Office will provide confirmation of dormant status and expected BMP inspection
frequency in writing to the permittee.
Permit No. NCG020000

Part III Page 3 of 5

In addition, also under dormant status but only upon a favorable site
inspection by the Regional Office, the Regional Office Engineer may exempt the
permittee from weekly and monthly BMP inspections in writing if stormwater
structural BMPs have been removed and the Regional Office determines that
structural BMPs are not necessary because of sufficient site stabilization. However,
the permittee must still perform an annual inspection as part of the SPPP
Annual Update outlined in 8. of this section. In either case, the permittee shall
notify the Regional Office prior to resuming industrial activities at an inactive mine.

A rain gauge and monitoring records are to be kept on site. BMPs shall be operated
and maintained. BMPs must be cleaned out when sediment storage capacity is at
50 percent of the design sediment volume. If visible sedimentation is leaving the
property, corrective action shall be taken to reduce the discharge of sediments.
Visible sedimentation shall be recorded with a brief explanation of measures taken
to prevent future releases, as well as any measures taken to remove the sediment
that has left the site. Visible sedimentation records shall be kept onsite. All other
stormwater specific controls (e.g. oil/water separators) shall be inspected and
qualitatively monitored (as per Part IV. C) on a semi-annual schedule. A log of all
sampling data, including activities taken to implement BMPs associated with vehicle
maintenance activities, shall be maintained and incorporated into the SPPP and kept
onsite and available for inspection purposes. These items shall be available for the
duration of the permit term and made available to the Director upon request. These
data shall be sent to the Regional Office upon request.

(c) Secondary Containment Requirements and Records. Secondary containment is
required for: bulk storage of liquid materials including petroleum products; storage
in any amount of Section 313 of Title III of the Superfund Amendments and
Reauthorization Act (SARA) water priority chemicals; and storage in any amount of
hazardous substances, in order to prevent leaks and spills from contaminating
stormwater runoff. A table or summary of all such tanks and stored materials and
their associated secondary containment areas shall be maintained. If the secondary
containment devices are connected to stormwater conveyance systems, the
connection shall be controlled by manually activated valves or other similar devices,
which shall be secured closed with a locking mechanism. Any stormwater that
accumulates in the containment area shall be at a minimum visually observed for
color, foam, outfall staining, visible sheens, and dry weather flow, prior to release of
the accumulated stormwater. Accumulated stormwater shall be released if found to
be uncontaminated by any material. Records documenting the individual making
the observation, the description of the accumulated stormwater, and the date and
time of the release shall be kept for a period of five (5) years. For the purposes of
effective stormwater pollution prevention, the SPPP is intended to be broader and
more comprehensive than a federal oil Spill Prevention, Control, and
Countermeasure Plan (SPCC). For facilities subject to a federal SPCC Plan, any
portion of the SPCC Plan fully compliant with the requirements of this permit may
be used to demonstrate compliance with this permit.

4. Spill Prevention and Response Procedures. The Spill Prevention and Response
Procedures (SPRP) shall incorporate an assessment of potential pollutant sources based on
a materials inventory of the facility. Facility personnel (or the team) responsible for
implementing the SPRP shall be identified in a written list incorporated into the SPRP and
signed and dated by each individual acknowledging their responsibilities for the
Permit No. NCG020000

Part III Page 4 of 5
procedures. A responsible person shall be on-site at all times during facility operations that
have increased potential to contaminate stormwater runoff through spills or exposure of
materials associated with the facility operations. The SPRP must be site stormwater
specific. Therefore, an oil Spill Prevention Control and Countermeasure Plan (SPCC) may be
a component of the SPRP, but may not be sufficient to completely address the stormwater
aspects of the SPRP. The common elements of the SPCC with the SPRP may be incorporated
by reference into the SPRP.

5. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance and good housekeeping program shall be developed and implemented. The
program shall ensure equipment used during mining activity on a site must be operated and
maintained to prevent potential pollution of the surface water or groundwaters of the state.
Fuels, lubricants, coolants, hydraulic fluids, or any other petroleum products shall not be
discharged on the ground or into surface waters. Spent lubricants and fuels shall be
disposed of properly and in accordance with applicable federal disposal regulations. Spilled
fluids shall be cleaned up to the maximum extent practicable and properly disposed of to
prevent entry to surface waters or groundwaters of the state. The program shall establish
schedules of inspections, maintenance, and housekeeping measures for vehicle
maintenance and industrial activity areas (including material storage and handling areas,
disposal areas, process areas, loading and unloading areas, and haul roads), where not
already addressed under another element of the SPPP. Timely compliance with the
established schedules for inspections, maintenance, and housekeeping shall be recorded
and maintained in the SPPP.

6. Employee Training. Training programs shall be developed and training provided at a
minimum on an annual basis for facility personnel with responsibilities for: spill response
and cleanup, preventative maintenance activities, and for any of the facility's operations
that have the potential to contaminate stormwater runoff. Additional required training
items include: used oil management, spent solvent management, and fueling procedures.
The annual training shall be documented by the signature and printed or typed name of
each employee trained.

7. Responsible Party. The SPPP shall identify a specific position(s) responsible for the
overall coordination, development, implementation, and revision to the SPPP.
Responsibilities for all components of the SPPP shall be documented and position
assignments provided.

8. SPPP Amendment and Annual Update. All aspects of the SPPP shall be reviewed and
updated on an annual basis. The permittee shall amend the SPPP whenever there is a
change in design, construction, operation, site drainage, maintenance, or configuration of
the physical features which may have a significant effect on the potential for the discharge
of pollutants to surface waters. The annual update shall include at a minimum:

(a) an updated list of significant spills or leaks of pollutants for the previous three (3)
years, or the notation that no spills have occurred (element of the Site Overview);
(b) a written re-certification that the stormwater outfalls have been evaluated for the
presence of non-stormwater discharges (element of the Site Overview);
(c) a documented re-evaluation of the effectiveness of the on-site stormwater BMPs;
(d) a review and comparison of sample analytical data to benchmark values (if applicable)
over the past year, including a discussion about Tiered Response status. The
permittee shall use the Division’s Annual Summary Data Monitoring Report (DMR)
Permit No. NCG020000

Part III Page 5 of 5
form, available from the Stormwater Permitting Program’s website (See ‘Monitoring
Forms’ here: http://portal.ncdenr.org/web/lr/npdes-stormwater).
(e) a comparison of the permittee’s estimate or record of the past year’s average daily and
maximum daily wastewater flow rates with the permittee’s estimate of the coming
year’s average daily and maximum daily wastewater flow rates, taking into account any
changes in the mine footprint or operational procedures anticipated in the coming
year. For any anticipated increased wastewater discharges into receiving waters
classified as HQW or ORW, the permittee shall compare the estimated increased
discharge flow rates to 50 percent of the receiving water 7Q10. (See Table 8, Footnote
7.)

The Director may notify the permittee when the SPPP does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall
submit a time schedule to the Director for modifying the SPPP to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with Part
V, Section B, Paragraph 5) to the Director that the changes have been made.

9. SPPP Implementation. The permittee shall implement the Stormwater Pollution
Prevention Plan and all appropriate BMPs consistent with the provisions of this permit, in
order to control contaminants entering surface waters via stormwater that comes in contact
with any overburden that is not stabilized, raw materials, intermediate products, finished
products, byproducts or waste products located on the site covered by this permit.

Implementation of the SPPP shall include documentation of all monitoring, measurements,
inspections, maintenance activities, and training provided to employees, including the log of
the sampling data and of actions taken to implement BMPs associated with the industrial
activities, including vehicle maintenance activities. Such documentation shall be kept on-
site for a period of five (5) years and made available to the Director or the Director’s
authorized representative immediately upon request.

PART IV – MONITORING, CONTROLS, AND LIMITATIONS FOR PERMITTED
DISCHARGES

SECTION A: STORMWATER DISCHARGES – ANALYTICAL MONITORING
REQUIREMENTS

Regulated industrial stormwater discharges are discharges of stormwater-only flows from
mining activity areas, including (but not limited to) areas of mine excavation, other land
disturbance, process areas, and vehicle maintenance. This section does not apply to wastewater
discharges from mine dewatering and process areas. Analytical monitoring for stormwater
discharges shall be performed for parameters as specified in Tables 1 through 3.

Monitoring Exemption
Analytical monitoring is not required for any basin or pond designed to contain the 25-year, 24-
hour storm (see Part VI, Definitions) without discharging, and that can regain capacity to hold such
an event within five (5) days’ time through means other than discharge to surface waters. A basin
or pond that meets this provision is considered a non-discharging stormwater control measure.

All analytical monitoring shall be performed during a measurable storm event at each stormwater
discharge outfall (SDO). Only SDOs discharging stormwater associated with industrial activity
must be sampled (See Definitions).

A measurable storm event for the purposes of this General Permit is a storm event that results
in an actual discharge from the permitted site outfall. The time between this storm event and
the previous measureable storm event must be at least 48 hours. See Definitions.

Footnotes:
1. Measurement Frequency: Twice per year (unless other provisions of this permit require monthly
sampling) during a measureable storm event, until either another permit is issued for this facility or
until this permit is revoked or rescinded. If the facility is monitoring monthly because of Tier Two or
Three response actions under the previous General Permit, the facility shall continue a monthly
monitoring and reporting schedule in Tier Two or Tier Three status until relieved by the provisions of
this permit or the Division.
2. Grab samples shall be collected within the first 30 minutes of discharge. Where physical separation
between outfalls prevents collecting all samples within the first 30 minutes, the permittee shall begin
sampling within the first 30 minutes, and shall continue until completed.
3. Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless
representative outfall status (ROS) has been granted. A copy of the Division’s letter granting ROS shall be
kept on site with the SPPP.
4. Turbidity must be monitored at the stormwater discharge outfall (SDO). In addition to the SDO, the
permittee may elect to also monitor turbidity in the receiving water, directly upstream (U) and
Permit No. NCG020000

Part IV Page 2 of 12 Pages
downstream (D) of the stormwater discharge outfall or group of outfalls to demonstrate the discharge
has not caused a water quality standard violation of turbidity. If SDO turbidity level exceeds the
benchmark, and the permittee cannot demonstrate the discharge has not caused a violation of the
instream water quality standard, the Division may require the permittee to monitor turbidity up-
and downstream as part of a Tier 2 or 3 response.
5. For each sampled measureable storm event the total precipitation must be recorded. An on-site rain
gauge or local rain gauge reading must be recorded.

The permittee shall complete the analytical samplings in accordance with the schedule specified in
Table 2. Sampling is not required outside of the facility’s normal operating hours (unless the mine
is inactive). A minimum of 60 days must separate Period 1 and Period 2 sample dates, unless
monthly monitoring has been instituted under other requirements of this permit.

Footnotes:
1. Maintain semi-annual monitoring during permit renewal process (unless other provisions of this permit
require monthly sampling). If at the expiration of the General Permit, the permittee has submitted an
application for renewal of coverage before the submittal deadline, the permittee will be considered for
renewed coverage. The applicant must continue monitoring until the renewed Certificate of Coverage
(COC) is issued.
2. If no discharge occurs during the sampling period, the permittee must record “No Flow” or “No
Discharge” within 30 days of the end of the sampling period in the facility’s monitoring records. “No
Flow” or “No Discharge” shall be reported on the Annual Summary Discharge Monitoring Report (DMR)
due by March 1.
3. Monitoring periods remain constant throughout the five-year term of the General Permit. For permittees
continuing with renewed coverage under this General Permit, Year 1 begins in Period 2 on October 1,
2015, and for all permittees Year 5 - Period 2 ends on September 30, 2020.

In all cases, the permittee shall report the analytical results from each sample within the
monitoring period (as specified in Part V, Standard Conditions, Section E) once a year (by March 1).
The permittee shall compare those results to the benchmark values in Table 3. Exceedances of
benchmark values require the permittee to increase monitoring, increase management actions,
increase record keeping, and/or install stormwater Best Management Practices (BMPs) in a tiered
program. Sample results that exceed benchmark values must be submitted no later than 30
days from the date the facility receives the sampling results (see Part V, Section E). Note that
Tier 1 and Tier 2 responses for turbidity benchmark exceedances are specifically outlined below Table
3 and differ from the Tier structure on page 4 of Part IV.

Permit No. NCG020000

Part IV Page 3 of 12 Pages
Table 3 Benchmark Values for Stormwater Discharges
Discharge Characteristics Benchmark Values
Settleable Solids 0.1 ml/l
Total Suspended Solids (TSS) 100 mg/l
TSS (ORW, HQW, trout, and PNA waters) 50 mg/l
Turbidity 50 NTU (See below)
Turbidity (lakes, reservoirs, salt waters) 25 NTU (See below)
Turbidity (freshwater streams, lakes, reservoirs
designated as trout waters) 10 NTU (See below)

The discharge shall not cause the turbidity of the receiving water to exceed Water Quality
Standards:

10 NTU (freshwater streams, lakes, and reservoirs designated as trout waters);
25 NTU (all lakes and reservoirs, and all salt waters);
50 NTU (all other streams and surface waters).

If turbidity of the receiving stream exceeds these levels due to natural background conditions, the
existing turbidity level shall not be increased as a result of the stormwater discharges.

The benchmark values in Table 3 are not enforceable permit limits. An exceedance of a
stormwater benchmark value is not a permit violation; however, failure to respond to the
exceedances as outlined in this permit is a violation of permit conditions. The benchmarks are
intended to reduce polluted discharges by triggering the permittee’s required response actions
under Tiers One, Two, and Three. See below the descriptions of Tiers One, Two, and Three
response actions (Standard “Tier Three” also applies to turbidity).

Tier One Response for Turbidity
If the first valid sampling result required for the monitoring period is above the turbidity benchmark at any outfall,
and the permittee cannot demonstrate the discharge has not caused or contributed to a Water Quality Standard
violation with up- and downstream sampling results, then the permittee shall:
1. Identify and evaluate possible causes of the benchmark exceedance within one week of receiving sample results.
2. Identify and implement feasible actions to improve turbidity levels in the discharge within one month.
3. Record each instance of a Tier One response for turbidity in the SPPP.

Tier Two Response for Turbidity
If the first valid sampling results required from two consecutive monitoring periods (omitting periods with no
discharge) are above the turbidity benchmark at any specific outfall, and the permittee cannot demonstrate the
discharge has not caused or contributed to a Water Quality Standard violation with up- and downstream sampling
results, then the permittee shall:
1. Repeat all the required actions outlined above in Tier One.
2. Contact the DEMLR Regional Office Engineer as provided below in Tier Three. The Regional Office Engineer may
direct the response actions on the part of the permittee as provided in Tier Three, including requiring the
permittee to sample up- and downstream of the SDO or group of SDOs. The Regional Office may work with the
permittee to designate appropriate instream sampling points and document that determination. The permittee
will be considered to be obligated under the Tier Three provisions.
3. Record each instance of a Tier Two response for turbidity in the SPPP.

Permit No. NCG020000

Part IV Page 4 of 12 Pages
Tier One
If: The first valid sampling results required for the monitoring period are above a benchmark value for any
parameter except turbidity at any outfall,
Then: The permittee shall:
1. Conduct a stormwater management inspection within two weeks of receiving the sample results.
2. Identify and evaluate possible causes of the benchmark value exceedance.
3. Identify potential, and select the specific feasible: source controls, operational controls, or physical
improvements to reduce concentrations of the parameters of concern.
4. Implement the selected feasible actions within two months of the inspection.
5. Record each instance of a Tier One response in the SPPP. Include the date and value of the benchmark
exceedance, the inspection date, the personnel conducting the inspection, the selected feasible actions, and
the date the selected feasible actions were implemented.
6. Note: Exceedances for a different parameter separately trigger the tiered response requirements.

Tier Two
If: The first valid sampling results from two consecutive monitoring periods (omitting periods with no discharge) are
above the benchmark values for any specific parameter except turbidity at a specific discharge outfall,
Then: The permittee shall:
1. Repeat all the required actions outlined above in Tier One.
2. Immediately institute monthly monitoring and monthly reporting for all parameters (including turbidity) at
every outfall where a sampling result exceeded the benchmark value for two consecutive samples. Monthly
(analytical and qualitative) monitoring shall continue until three consecutive sample results are below the
benchmark values.
3. If no discharge occurs during the sampling period, the permittee is required to submit a monthly monitoring
report indicating “No Flow” to comply with reporting requirements.
4. Alternatively, in lieu of steps 2 and 3, the permittee may exercise the option of contacting the DEMLR Regional
Office Engineer as provided below in Tier Three. The Regional Office Engineer may direct the response
actions on the part of the permittee as provided in Tier Three. The permittee will be considered to be
obligated under the Tier Three provisions.
5. Maintain a record of the Tier Two response in the SPPP.
6. Continue Tier Two response obligations throughout the permit COC renewal process.

Tier Three
If the valid sampling results required for the permit monitoring periods exceed the benchmark value for any
specific parameter (including turbidity) at any specific outfall on four occasions, the permittee shall notify the
DEMLR Regional Office Engineer in writing within 30 days of receipt of the fourth analytical results. DEMLR
may but is not limited to:

x require the permittee to revise, increase, or decrease the monitoring and reporting frequency for some or
all parameters, including requiring sampling of additional or substitute parameters;
x rescind coverage under the General Permit, and require that the permittee apply for an individual
stormwater discharge permit;
x require the permittee to install structural stormwater controls;
x require the permittee to implement other stormwater control measures;
x require the permittee to perform upstream and downstream monitoring to characterize impacts on
receiving waters; or
x require the permittee to continue Tier Three obligations through the permit COC renewal process.

Permit No. NCG020000

Part IV Page 5 of 12 Pages
Failure to monitor and report per the permit terms may result in the Division requiring
monthly monitoring and reporting for all parameters for a specified time period. Lack of a
discharge from an outfall for the monitoring period, or inability to collect a sample because of
adverse weather conditions during a monitoring period will not constitute failure to monitor, as
long as those conditions are reported on the monitoring period DMR and noted in the SPPP. (See
Adverse Weather in Definitions.) Similarly, sampling is not required outside of the facility’s normal
operating hours (unless the mine is inactive).

Reduced monitoring for inactive mines: Dormant Site Status is available for inactive mine sites that
have suspended all industrial activities, and if the permittee has certified in writing to DEMLR’s
Stormwater Permitting Program that all portions of the site with clearing, grading, and/or
excavation activities have been stabilized with vegetation. Upon a favorable site inspection by the
Regional Office, the Regional Office Engineer may exempt the permittee from stormwater analytical
monitoring, stormwater qualitative monitoring, and wastewater monitoring. The DEMLR letter
granting dormant status must be kept with the SPPP, and available for inspection within a
reasonable time of the Division’s request.

In the event that the Division releases the permittee from continued monthly monitoring and reporting
under Tier Two or Tier Three, DEMLR’s release letter may remain in effect through subsequent
reissuance of this permit, unless the release letter provides for other conditions or duration.

The permittee must report all results from all valid discharge samples taken during each
monitoring period. However, for purposes of benchmark comparison and Tiered response actions, the
permittee shall use the analytical results from the first sample with valid results within the
monitoring period.

SECTION B: STORMWATER DISCHARGES – ON-SITE VEHICLE MAINTENANCE
MONITORING REQUIREMENTS

Facilities that have any on-site vehicle maintenance activity that uses more than 55 gallons of
new motor oil per month when averaged over the calendar year shall perform analytical
monitoring as specified below in Table 4 and in accordance with the schedule presented in Table 2
(Section A). Sampling results shall be reported as described in Part V, Section E. All analytical
monitoring shall be performed during a measureable storm event at all stormwater discharge
outfalls (SDOs) that discharge stormwater runoff from vehicle maintenance areas.

1. Measurement Frequency: Twice per year (unless other provisions of this permit require monthly
sampling) during a measureable storm event (See Table 2), until either another permit is issued
for this facility or until this permit is revoked or rescinded. If the facility is monitoring monthly
because of Tier Two or Three response actions under the previous General Permit, the facility shall
continue a monthly monitoring and reporting schedule in Tier Two or Tier Three status until relieved
by the provisions of this permit or the Division.
2. Grab samples shall be collected within the first 30 minutes of discharge. Where physical separation
between outfalls prevents collecting all samples within the first 30 minutes, the permittee shall begin
sampling within the first 30 minutes, and shall continue until completed.
3. Sample Location: Samples shall be collected at each vehicle maintenance area stormwater
discharge outfall (SDO), unless representative outfall status (ROS) has been granted. A copy of the
Division’s letter granting ROS shall be kept on site with the SPPP.
4. For each sampled measureable storm event, an on-site or local rain gauge reading must be
recorded. Where isolated sites are unmanned for extended periods of time, a local rain gauge
reading may be substituted for an on-site reading.

The permittee shall complete the analytical samplings in accordance with the schedule specified in
Table 2. A minimum of 60 days must separate Period 1 and Period 2 sample dates unless monthly
monitoring has been instituted under other requirements of this permit.

In all cases, the permittee shall report the analytical results from each sample within the
monitoring period (as required in Part V, Standard Conditions, Section E.) once a year (by March 1).
The permittee shall compare those results to the benchmark values in Table 5. Exceedances of
benchmark values require the permittee to increase monitoring, increase management actions,
increase record keeping, and/or install stormwater Best Management Practices (BMPs) in a tiered
program. See the descriptions of the Tiers One, Two, and Three required response actions in
Section A. Sample results that exceed benchmark values must be submitted no later than 30 days
from the date the facility receives the sampling results (see Part V, Section E).

Table 5 Benchmark Values for On-Site Vehicle Maintenance Activities

The benchmark values in Table 5 are not enforceable permit limits. An exceedance of a stormwater
benchmark value is not a permit violation; however, failure to respond to the exceedances as outlined
in this permit is a violation of permit conditions. The benchmarks are intended to reduce polluted
discharges by triggering the permittee’s required response actions under Tiers One, Two, and Three.

Failure to monitor and report per the permit terms may result in the Division requiring
monthly monitoring and reporting for all parameters for a specified time period. Lack of a
discharge from an outfall for the monitoring period, or inability to collect a sample because of
adverse weather conditions during a monitoring period will not constitute failure to monitor vehicle
maintenance area discharges, as long as those conditions are reported on the monitoring period
DMR and noted in the SPPP. (See Adverse Weather in Definitions.) Similarly, sampling is not
required outside of the facility’s normal operating hours (unless the mine is inactive).

SECTION C: STORMWATER DISCHARGES – QUALITATIVE MONITORING
REQUIREMENTS

The purpose of qualitative monitoring is to implement a quick and inexpensive way to evaluate the
effectiveness of the permittee’s SPPP and to identify the potential for new sources of stormwater
pollution. Qualitative monitoring of stormwater outfalls must be performed during a measurable
storm event.

Qualitative monitoring requires a visual inspection of each stormwater outfall. Qualitative
monitoring shall be performed as specified in Table 6, whether semi-annual or more frequently as
may be required per the Qualitative Monitoring Response requirements below. Inability to
monitor because of adverse weather or lack of discharge during the monitoring period must be
documented in the SPPP and recorded on the Qualitative Monitoring Report (see Adverse Weather
in Definitions). Similarly, monitoring is not required outside of the facility’s normal operating
hours (unless the mine is inactive). Only SDOs discharging stormwater associated with industrial
activity must be monitored (See Definitions).

In the event an atypical condition is noted at a stormwater discharge outfall, the permittee shall
document the suspected cause of the condition and any actions taken in response to the discovery.
This documentation will be maintained with the SPPP.

Footnotes:
1. Monitoring Frequency: Twice per year (unless other provisions of this permit prompt other
frequency) during a measureable storm event. See Table 2 for schedule of monitoring periods.
The permittee must continue qualitative monitoring throughout the permit renewal process.
2. Monitoring Location: Qualitative monitoring shall be performed at each stormwater discharge outfall
(SDO) regardless of representative outfall status (ROS), unless ROS is granted specifically for
qualitative monitoring. A copy of any letter granting ROS shall be kept on site. DEMLR’s letter
granting ROS remains in effect through the subsequent reissuance of this permit and as long as the
pertinent site conditions and operations remain unchanged, unless the ROS letter provides for other
conditions or duration.

Permit No. NCG020000

Part IV Page 8 of 12 Pages
Representative outfall status (ROS) specifically for qualitative monitoring may be granted for some
stormwater outfalls and must be documented by DEMLR. Qualitative monitoring records shall not
be turned into the Division except when requested. Qualitative monitoring records shall be
maintained on site as part of the SPPP.

A minimum of 60 days must separate monitoring dates, unless additional sampling has been
instituted as part of other analytical monitoring requirements in this permit.

If the permittee’s qualitative monitoring indicates that existing stormwater BMPs are ineffective, or
that significant stormwater contamination is present, the permittee shall investigate potential
causes, evaluate the feasibility of corrective actions, and implement those feasible corrective
actions within 60 days, per the Qualitative Monitoring Response, below. A written record of the
permittee’s investigation, evaluation, and response actions shall be kept in the SPPP.

Qualitative Monitoring Response

Qualitative monitoring is for the purposes of evaluating SPPP effectiveness, identifying the potential
for new sources of stormwater pollution, and prompting the permittee’s response to pollution. If
the permittee repeatedly fails to respond effectively to correct problems identified by qualitative
monitoring, or if the discharge causes or contributes to a water quality standard violation, DEMLR
may but is not limited to:

x require that the permittee revise, increase, or decrease monitoring frequency for some or
all parameters (analytical or qualitative);
x require the permittee to install structural stormwater controls;
x require the permittee to implement other stormwater control measures; or
x require the permittee to perform upstream and downstream monitoring to characterize
impacts on receiving waters.

SECTION D: WASTEWATER DISCHARGES – ANALYTICAL MONITORING
REQUIREMENTS AND EFFLUENT LIMITATIONS

This General Permit authorizes the discharge of process wastewater associated with two distinct
activities: 1) mine dewatering and 2) process wastewater associated with mining operations as
described below in 1.-4. of this Section. The authorization to discharge wastewater is specifically
identified on each permittee’s COC. Process wastewater discharges generated by any other
activity are not authorized under this permit, except allowable non-stormwater discharges
permitted by 15A NCAC 2H .0106(f). Mine dewatering or other wastewaters commingled with
stormwater shall be considered wastewater.

1. MINE DEWATERING WASTEWATER

During the period beginning on the effective date of the permit and lasting until expiration, the
permittee is authorized to discharge mine dewatering wastewater controlled in accordance with
the conditions of this permit. Mine dewatering requirements apply to all mines that dewater from
pits including quarries, clay brick, sand and gravel, borrow pits, and refractory mining, as well as
mines with similar discharges. See Part VI (Definitions) and federal regulations in 40 CFR §436 for
definitions of the terms “mine dewatering” and “mine” specific to industry sub-sectors. For
Construction Sand and Gravel or Industrial Sand mines, “mine dewatering” wastewater includes
wet pit overflows caused solely by direct rainfall and groundwater seepage.

Permittees conducting mine dewatering activities that have the potential to drain wetlands
or other surface waters must have developed and implemented a Pumping Operation
and Monitoring (POM) Plan approved by the Division. Approval may be coordinated
with other Divisions in NC DEQ, such as the Division of Water Resources. POM Plans
shall include, but are not limited to:

x Groundwater monitoring strategies to demonstrate the effect of pumping.
x Detailed plans to maintain the surrounding hydrology that protects the affected
streams and wetlands and the respective monitoring to demonstrate compliance.
x The pumping regime deemed necessary to protect affected streams and wetlands.

Alternative site specific pumping and monitoring regimes may be approved by the
Division on a case-by-case basis. At the Division’s discretion, approval of the POM Plan
may be required prior to coverage under this General Permit.

Mine dewatering discharges to land surfaces (without the potential to discharge directly to
surface waters), where no chemicals are used in the mining process, may be permitted by regulation
under 15A NCAC 02T .0113(a)(16) and therefore not subject to the provisions of this permit.

2. PROCESS WASTEWATER

During the period beginning on the effective date of the permit and lasting until expiration, the
permittee is authorized to discharge treated process wastewater from mining operations. Process
wastewater from mining operations includes, but may not be limited to, the water involved in: the
slurry transport, washing, or sawing of mined material; air emissions control or processing exclusive
of mining of sand, gravel, and stone washing operations; dimension stone cutting operations; and air
scrubbing and dust control operations. See Part VI (Definitions) and federal regulations for
definitions of the terms “process wastewater” in 40 CFR §122.2 and “process generated wastewater”
specific to mining industry sub-sectors in 40 CFR §436. Treatment may involve conveyance through
erosion and sedimentation control (E&SC) structures and/or other engineered treatment systems.
Permit No. NCG020000

Part IV Page 10 of 12 Pages

3. COMMINGLED STORMWATER AND WASTEWATER DISCHARGES

If mine dewatering or authorized process wastewaters commingle with stormwater prior to
discharge, sampling the combined discharge under this Section D will meet the monitoring
requirements of this permit. Sampling shall be performed during the discharge; these events may or
may not be associated with rainfall.

4. RECYCLE SYSTEMS

Authorized process wastewater discharges (overflows) from a recycle system to surface waters are
subject to the provisions, monitoring requirements, and effluent limitations in this General Permit.

MONITORING FOR MINE DEWATERING AND AUTHORIZED PROCESS WASTEWATER
DISCHARGES

Analytical monitoring of mine dewatering and authorized process wastewater shall be performed
as specified below in Table 7. For each parameter, an effluent limitation is contained in Table 8.
An exceedance of any of these limitations results in a violation of the permit conditions and may be
subject to enforcement action as specified in Part V, Section A.2 of this permit. In all cases, the
permittee shall report the analytical results from each sample within the monitoring period (as
specified in Part V, Standard Conditions, Section E) once a year (by March 1). Sample results that
exceed an effluent limitation must be submitted to the Regional Office no later than 30 days from
the date the facility receives the sampling results (see Part V, Section E).

Footnotes:
1. The monitoring frequency is quarterly for the first year (see Table 9), and then semi-annually. If a
sample concentration exceeds any effluent limit in Table 8, monitoring frequency (all parameters)
shall return to (or remain) quarterly, until four (4) consecutive quarterly samples all meet or are below
the limit for all parameters, allowing the permittee to resume/reduce to semi-annual monitoring.
2. Except for mine dewatering of clay pits, a grab sample is not required for these parameters from a
basin/pond designed to contain or treat mine dewatering wastewater that only discharges in
response to rainfall in excess of the 10-yr, 24-hr storm.
3. Sample Location: E – Effluent, U – Upstream, D – Downstream. Turbidity must be monitored at the
effluent (E). If effluent levels exceed the Water Quality Standard of the receiving water, the permittee
must begin sampling turbidity directly upstream (U) and downstream (D) of the effluent outfall or group
of outfalls, in addition to the effluent, upon the next monitoring period. The permittee may contact the
Permit No. NCG020000

Part IV Page 11 of 12 Pages
DEMLR Regional Office for assistance in determining the best instream sample points. The RO may also
advise the permittee to relocate self-established instream sample points if appropriate.
4. All facilities that are mining Industrial Sand are required to monitor TSS and are subject to the TSS
limits in Table 8. All other types of mines covered by this permit are also required to monitor TSS, but
are not necessarily subject to the TSS limits in Table 8, unless discharge is to HQW, ORW, or PNA waters.
5. Only facilities discharging to waters classified as HQW, ORW, SA, SB, Tr, or PNA are required to monitor
for settleable solids.
6. Only facilities discharging to waters classified as SA waters are required to monitor for fecal coliform.
7. Daily flow rate shall be recorded by a continuous flow measurement instrument. Alternatively, pump
curves and pump logs may be used as a means to calculate the daily flow rate.

Footnotes:
1. Note that for a semi-annual or quarterly sampling schedule, the sample result counts as both the Daily
Maximum and Monthly Average value. More frequent samples may be conducted to calculate averages
but must all be reported to NC DEQ.
2. Limits applicable to Industrial Sand mines. More stringent water quality-based TSS limits apply to all
mines that discharge to High Quality Waters (HQW), including HQWs and ORWs that are trout waters
(Tr), and Primary Nursery Area (PNA) waters (See 3.).
3. Monthly Average and Daily Maximum TSS Limits apply to all discharges (regardless of mine type) to
waters designated as HQW, ORW, HQW/ORW Tr, and PNA.
4. Designated swamp waters can have a pH as low as 4.3 because of natural conditions. In such cases,
Federal Effluent Guidelines (40 CFR §436) allow the lower range of the pH limitations to be adjusted
downward to no lower than 5.0. The permittee must sample instream to demonstrate a lower limit is
appropriate.
5. No limit in the effluent discharge applies, but turbidity in the receiving waters shall not exceed levels
described below as a result of wastewater discharges.
6. The total daily flow rate of wastewater for all discharges combined (that discharge to the same receiving
waters) shall not exceed 50 percent of the total in-stream flow rate of the receiving waters under 7Q10
conditions in HQW/ORW waters, including HQW/ORW trout and PNA waters.

The discharge shall not cause the turbidity of the receiving water to exceed Water Quality
Standards:

10 NTU (freshwater streams, lakes, and reservoirs designated as trout waters);
25 NTU (all lakes and reservoirs, and all salt waters);
50 NTU (all other streams and surface waters).

Permit No. NCG020000

Part IV Page 12 of 12 Pages
This General Permit requires the measurement of turbidity in the permittee’s discharge, but does
not impose a turbidity effluent limit. If turbidity of the receiving stream exceeds these levels due to
natural background conditions, the existing turbidity level shall not be increased. If the turbidity
in-stream exceeds these levels as a result of wastewater discharges, this water quality standard
violation subjects the permittee to possible compliance and enforcement action.

The permittee shall complete the analytical samplings of wastewater discharges in accordance with
the schedule specified in Table 9.

1. Maintain quarterly (or semi-annual) monitoring during permit renewal. If at the expiration of the
General Permit, the permittee has submitted an application for renewal of coverage before the submittal
deadline, the permittee will be considered for renewed coverage. The applicant must continue
monitoring until the renewed Certificate of Coverage (COC) is issued.
2. If no discharge occurs during the sampling period, the permittee must record “No Flow” or “No
Discharge” within 30 days of the end of the sampling period in the facility’s monitoring records. “No
Flow” or “No Discharge” shall be reported on the Annual Summary Discharge Monitoring Report (DMR).
This DMR is to be submitted to the Division of Water Resource’s Central Files at the DWR Central Office
by March 1 of each year (in accordance with Part V, Section E).
3. Monitoring periods remain constant throughout the five-year term of the General Permit. For permittees
continuing with renewed coverage under this General Permit, Year 1 begins in Period 4 on October 1,
2015, and for all permittees Year 5 - Period 4 ends on September 30, 2020.

Failure to monitor and report per the permit terms may result in the Division requiring
monthly monitoring and reporting for all parameters for a specified time period.

SECTION E: BMP CONDITIONS AND RESIDUALS MANAGEMENT

1. BMPS FOR BLASTING AND FLOCCULANTS

The permittee shall utilize best management practices (BMPs) to ensure that contaminants do not
enter the surface waters as a result of blasting at the site. Flocculants evaluated by the Division
may be used if administered in accordance with maximum application doses and any other current
requirements.

2. RESIDUALS MANAGEMENT

The residuals generated from treatment facilities used to meet the effluent limitations must be
disposed of in accordance with applicable standards and in a manner such as to prevent any
pollutants from such materials from entering waters of the state or navigable waters of the United
States.

SECTION C: OPERATION AND MAINTENANCE OF POLLUTION CONTROLS

1. Proper Operation and Maintenance
The permittee shall at all times properly operate and maintain all facilities and systems of treatment
and control (and related appurtenances) which are installed or used by the permittee to achieve
compliance with the conditions of this permit. Proper operation and maintenance also includes
adequate laboratory controls and appropriate quality assurance procedures. This provision requires
the operation of back-up or auxiliary facilities or similar systems which are installed by a permittee
only when the operation is necessary to achieve compliance with the conditions of this permit [40
CFR 122.41(e)].

2. Need to Halt or Reduce Not a Defense
It shall not be a defense for a permittee in an enforcement action that it would have been necessary
to halt or reduce the permitted activity in order to maintain compliance with the condition of this
General Permit [40 CFR 122.41(c)].

3. Bypassing of Stormwater Control Facilities at Mine Sites Covered by NCG020000
Bypass is prohibited, and the Permit Issuing Authority may take enforcement action against a
permittee for bypass unless:
a. Bypass was unavoidable to prevent loss of life, personal injury or severe property damage; and
b. There were no feasible alternatives to the bypass, such as the use of auxiliary control facilities,
retention of stormwater, or maintenance during normal periods of equipment downtime or dry
weather. This condition is not satisfied if adequate backup controls should have been installed in
the exercise of reasonable engineering judgment to prevent a bypass which occurred during
normal periods of equipment downtime or preventive maintenance; and
c. The permittee submitted notices as required under Part V, Section E of this General Permit.

If the Permit Issuing Authority determines that it will meet the three conditions listed above, the
Permit Issuing Authority may approve an anticipated bypass after considering its adverse effects.

4. Bypassing of Wastewater Treatment Facilities at Mine Sites Covered by NCG020000
a. Bypass not exceeding limitations [40 CFR 122.41(m)(2)]

bypasses are not subject to the provisions of Paragraphs b. and c. of this section.
b. Notice [40 CFR 122.41(m)(3)]
Permit No. NCG020000

Part V Page 7 of 11
(1) Anticipated bypass. If the Permittee knows in advance of the need for a bypass, it shall
submit prior notice, if possible at least ten days before the date of the bypass; including an
evaluation of the anticipated quality and effect of the bypass.
(2) Unanticipated bypass. The Permittee shall submit notice of an unanticipated bypass as
required in Part V, Section E of this General Permit.
c. Prohibition of Bypass
(1) Bypass from the wastewater treatment facility is prohibited, and the Permit Issuing
Authority may take enforcement action against a Permittee for bypass, unless:
(A) Bypass was unavoidable to prevent loss of life, personal injury or severe property
damage;
(B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment
facilities, retention of untreated wastes or maintenance during normal periods of
equipment downtime. This condition is not satisfied if adequate backup equipment
should have been installed in the exercise of reasonable engineering judgment to
prevent a bypass which occurred during normal periods of equipment downtime or
preventive maintenance; and
(C) The Permittee submitted notices as required under Paragraph b. of this section.
(2) The Permit Issuing Authority may approve an anticipated bypass, after considering its
adverse effects, if the Permit Issuing Authority determines that it will meet the three
conditions listed above in Paragraph c. (1) of this section.

SECTION D: MONITORING AND RECORDS

l. Representative Sampling
Samples collected and measurements taken, as required herein, shall be characteristic of the volume
and nature of the permitted discharge. Analytical sampling shall be performed during a measureable
storm event. Samples shall be taken on a day and time that is characteristic of the discharge. All
samples shall be taken before the discharge joins or is diluted by any other waste stream, body of
water, or substance. Monitoring points as specified in this General Permit shall not be changed
without notification to and approval of the Permit Issuing Authority [40 CFR 122.41(j)].

2. Recording Results
For each measurement or sample taken pursuant to the requirements of this General Permit, the
permittee shall record the following information [40 CFR 122.41]:
a. The date, exact place, and time of sampling or measurements;
b. The individual(s) who performed the sampling or measurements;
c. The date(s) analyses were performed;
d. The individual(s) who performed the analyses;
e. The analytical techniques or methods used; and
f. The results of such analyses.

3. Flow Measurements
Where required, appropriate flow measurement devices and methods consistent with accepted
scientific practices shall be selected and used to ensure the accuracy and reliability of measurements

published pursuant to Section 304(g), 33 USC 1314, of the Federal Water Pollution Control Act, as
Amended, and Regulation 40 CFR 136.

To meet the intent of the monitoring required by this General Permit, all test procedures must
produce minimum detection and reporting levels and all data generated must be reported down to
the minimum detection or lower reporting level of the procedure. If no approved methods are
determined capable of achieving minimum detection and reporting levels below the General Permit
discharge requirements, then the most sensitive (method with the lowest possible detection and
reporting level) approved method must be used.

5. Representative Outfall
If a facility has multiple discharge locations with substantially identical stormwater discharges that
are required to be sampled, the permittee may petition the Director for representative outfall status.
If it is established that the stormwater discharges are substantially identical and the permittee is
granted representative outfall status, then analytical sampling requirements may be performed at a
reduced number of outfalls.

6. Records Retention
Visual monitoring shall be documented and records maintained at the facility along with the
Stormwater Pollution Prevention Plan (SPPP). Copies of analytical monitoring results shall also be
maintained on-site or be available electronically to a DEMLR inspector upon request. The permittee
shall retain records of all monitoring information, including
o all calibration and maintenance records,
o all original strip chart recordings for continuous monitoring instrumentation,

land treatment facility, a surface impoundment, an injection well, a hazardous waste long-term
storage facility or a surface storage facility.

15. Measureable Storm Event
A storm event that results in an actual discharge from the permitted site outfall. The previous
measurable storm event must have been at least 48 hours prior (applies specifically to this
NCG020000 General Permit). The 48-hour storm interval may not apply if the permittee is able to
document that a shorter interval is representative for local storm events during the sampling period,
and obtains approval from the local DEMLR Regional Office. Two copies of this information and a
written request letter shall be sent to the local DEMLR Regional Office. After authorization by the
DEMLR Regional Office, a written approval letter must be kept on site in the permittee’s SPPP.

16. Mine Dewatering
See Code of Federal Regulations for definition applicable to specific mineral mining subcategories in
40 CFR Part 436. The term “mine dewatering” (wastewater) means any water that is impounded or
that collects in the mine and is pumped, drained, or otherwise removed from the mine through the
efforts of the mine operator. For the Construction Sand and Gravel Subcategory and Industrial
Sand Subcategory, “mine dewatering” also includes wet pit overflows caused solely by direct rainfall
and ground water seepage. In this context, and also from 40 CFR Part 436, the term “mine” means an
area of land, surface or underground, actively mined for the production of either crushed and broken
stone (Crushed Stone Subcategory), sand and gravel (Construction Sand and Gravel, Industrial Sand
Subcategories), or other mine product, from natural deposits.

17. Municipal Separate Storm Sewer System (MS4)
A stormwater collection system within an incorporated area of local self-government such as a city or
town.

18. No Exposure
A condition of no exposure means that all industrial materials and activities are protected by a storm
resistant shelter or acceptable storage containers to prevent exposure to rain, snow, snowmelt, or
runoff. Industrial materials or activities include, but are not limited to, material handling equipment
or activities, industrial machinery, raw materials, intermediate products, by-products, final products,
or waste products. DEMLR may grant a No Exposure Exclusion from NPDES stormwater permitting
Permit No. NCG020000

notice of intent to seek coverage under a general permit.

20. Permit Issuing Authority
The Director of the Division of Energy, Mineral, and Land Resources (see “Director” above).

21. Permittee
The owner or operator issued a Certificate of Coverage pursuant to this General Permit.

22. Point Source Discharge of Stormwater
Any discernible, confined and discrete conveyance including, but not specifically limited to, any pipe,
ditch, channel, tunnel, conduit, well, or discrete fissure from which stormwater is or may be
discharged to waters of the state.

23. Process Generated Wastewater
See Code of Federal Regulations for definition applicable to specific mineral mining subcategories in
40 CFR Part 436.

24. Process Wastewater
Any water which, during manufacturing or processing, comes into direct contact with or results from
the production or use of any raw material, intermediate product, finished product, byproduct, or
waste product See Code of Federal Regulations in 40 CFR Part 122.2.

25. Representative Outfall Status
When it is established that the discharge of stormwater runoff from a single outfall is representative of the
discharges at multiple outfalls, the DEMLR may grant representative outfall status. Representative outfall
status (ROS) allows the permittee to perform analytical monitoring at a reduced number of outfalls.

26. Secondary Containment
Spill containment for the contents of the single largest tank within the containment structure plus
sufficient freeboard to contain the 25-year, 24-hour storm event.

27. Section 313 Water Priority Chemical
A chemical or chemical category which:
b. Is listed in 40 CFR 372.65 pursuant to Section 313 of Title III of the Superfund Amendments and
Reauthorization Act (SARA) of 1986, also titled the Emergency Planning and Community Right-
to-Know Act of 1986;
c. Is present at or above threshold levels at a facility subject to SARA title III, Section 313 reporting
requirements; and
d. Meets at least one of the following criteria:
i. Is listed in appendix D of 40 CFR Part 122 on Table II (organic priority pollutants), Table
III (certain metals, cyanides, and phenols) or Table IV (certain toxic pollutants and
hazardous substances);
ii. Is listed as a hazardous substance pursuant to section 311(b)(2)(A) of the CWA at 40 CFR
116.4; or
iii. Is a pollutant for which EPA has published acute or chronic water quality criteria.
