Subject: RE: NCG020157
Autumn,
mentioned to Myrl on the phone about the outfall clog, I wanted to give you an update. There was a very small stream
flowing through a 24" pipe from our first pond to a drainage ditch and then there was no discharge at the outfall. Upon
further inspection we found debris caught inside of the 24" pipe which we cleaned out. When we inspected the drainage
ditch we observed where flow had been dammed by a beaver in several locations. We busted up the dams and plan to
walk the ditch during our inspections of the outfall. We now have flow again. If you have any questions let me know, my
phone number is [phone] ext 1006.

Randy, in the memo below Bethany comments about a change of ownership. You stated in your initial call to me that
you were from Piedmont Minerals, so that is what made us wonder. I presume the correct permit owner is still Resco. If
not contact me again for a change of ownership form.
I will notify Autumn concerning the clogged outfall.

Myrl,
Attached is a copy of the renewal letter (last page) and forms we sent out in 2009. They need to fill these out and get
them back to us. Even though they've been paying fees (and we'll likely renew without question because of that), their
obligation was to get these forms back to us when they received them the first time. They also need to notify us if
there's been a change in ownership.
Let us know if you have any other questions,

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 Water Quality (DWQ) 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 process wastewater that has a point source
discharge to the surface waters of the state.
This General Permit covers 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 Site Plan, as outlined in the
Stormwater Pollution Prevention Plan (SPPP), Part I1I, Section A.
Parts I -II Page 1 of 4

Permit No. NCG020000
SECTION B: PERMITTED ACTIVITIES
Until this permit expires or is modified or revoked, the permittee is authorized to discharge
stormwater, mine dewatering, and/or process wastewater to the surface waters of North Carolina
or a separate storm sewer system which has been adequately treated and managed in accordance
with the terms and conditions of this General Permit. Types of approved discharges are
dependent upon approval and are detailed in the permittee's individual Certificate of
Coverage (COC). All discharges shall be in accordance with the conditions of this 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. If
mining activities will expand or change such that the types of discharges are affected, the permittee
is to contact DWQ to determine if modifications to the COC are necessary first The permittee is also
responsible for contacting the Division of Land Resources (DLR) if modifications to the Mining
Permit are necessary, as compliance with the Mining Permit is a stipulation of this permit.
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 213.0230 and .0231 and water quality certification requirements
as outlined in 15A NCAC 2H .0500. 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.
PART II - AUTHORIZATION TO CONSTRUCT AND OPERATE A TREATMENT FACILITY
Mining operations involving construction and operation of wastewater treatment facilities for
mine dewatering or process wastewater (such as saw water, wash water, etc.) are subject to
construction and operation requirements for treatment facilities as outlined in Sections A and B
below.
SECTION A: REQUIREMENTS FOR CONSTRUCTING NEW OR EXPANDING
WASTEWATER TREATMENT FACILITIES
All new or expanding wastewater treatment facilities must receive an Authorization to
Construct [AtC) from DWQ unless specifically excluded in Part III, Section E in this permit.
Treatment facility arrangements excluded from the AtC requirement are as follows:
♦ Dewatering wastewater directly pumped from the pit through erosion and
sedimentation control facilities and that does not require additional treatment other
than those structures to meet effluent limits prior to discharge.
♦ Water conveyed from mined sand and/or gravel through erosion and
sedimentation control facilities and that does not require additional treatment other
than those structures to meet effluent limits prior to discharge.
♦ Closed -loop process recycle wastewater systems that are designed to operate with
a minimum of two feet (2') of freeboard and that limit the water entering the system to
makeup water and/or precipitation that falls directly into the system (i.e., exclude
stormwater runoff from draining into the system).
♦ Facilities designed to administer polyacrylamides (PAMS) or other chemical
flocculant materials, as long as administered in accordance with Division requirements
and that do not require additional treatment other than those structures to meet
effluent limits prior to discharge.
Parts I -II Page 2 of 4

Permit No. NCG020000
Treatment facility arrangements that are subject to AtC requirement include, but are
not limited to:
Dewatering wastewater treatment facilities for discharges that do not meet effluent
limits and do not protect water quality standards.
Process recycle wastewater systems that are not designed to operate with a
minimum of two feet (2`) of freeboard and/or do not otherwise meet criteria to be
considered closed -loop recycle system (i.e., Non -closed -loop recycle systems).
2. Application for the AtC requires that plans and specifications be submitted to the Division of
Water Quality, Stormwater Permitting Unit, 1617 Mail Service Center, Raleigh, NC 27699-
1617 for approval.
3. Upon approval of the plans and specifications by the Division, a set of approved plans and
specifications for the subject project will be returned to the permittee. These plans must be
retained by the permittee for the life of the treatment facility.
4. Upon receipt of an approved AtC, approved treatment facilities shall be constructed and
implemented in accordance with the conditions of this permit, approved plans and
specifications, and other supporting data. Treatment facilities shall be constructed to meet
the effluent limitations in Part III, Section E of this General Permit. All such inspections
must be documented with printed name, date, and signature of individual performing the
inspection(s).
S. Upon completion of construction and prior to operation of a permitted facility, a
certification of plans and specifications must be received from a professional engineer in
accordance with G.S. 89-25 certifying that the permitted facility has been installed in
accordance with this permit, the approved plans and specifications, and other supporting
materials. Mail the Certification of plans and specifications to the Division of Water Quality,
Stormwater Permitting Unit, 1617 Mail Service Center, Raleigh, NC 27699-1617.
6. The permittee shall notify the DWQ Regional Office at least seventy-two (72) hours in
advance of operation of the installed facilities so that an in -place inspection can be made if
the Regional Office so desires. Such notification to the Regional Supervisor shall be made
during normal business hours from 8:00 a.m. until 5:00 p.m. on Monday through Friday,
excluding State Holidays.

conditions, the permittee shall take immediate corrective action, including those actions
that may be required by this Division, 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.
S. 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 the Division, shall
be provided.
7. Flocculants evaluated by the Division 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

Permit No. NCG020000
PART III — MONITORING, CONTROLS, AND LIMITATIONS FOR PERMITTED
DISCHARGES
SECTION A: STORMWATER POLLUTION AND PREVENTION PLAN (SPPP)
All permittees shall develop and implement a Stormwater Pollution Prevention Plan (SPPP),
herein after referred to as the Plan. This Plan shall be considered public information in accordance
with Part IV, Standard Conditions, Section E, Paragraph 3 of this General Permit. The Plan shall
include, at a minimum, the following items:
1. Site Plan. The site plan 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 plan 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 accurate latitude
and longitude of the point(s) of discharge. 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 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,,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 areas for each outfall, direction of flow in
each drainage area, industrial activities occurring in each drainage area, buildings,
existing 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 distance legend. In addition, the following industrial activity areas must
also be identified on the site map: fueling, engine maintenance and repair, vessel
maintenance and repair, washing, painting, sanding, blasting, welding, and metal
fabrication.
(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 certification statement will be signed in
accordance with the requirements found in Part IV, Standard Conditions, Section B,
Paragraph S. The permittee shall re -certify annually that the stormwater
outfalls have been evaluated for the presence of non-stormwater discharges.
Part III Page 1 of 16 Pages

Permit No. NCG020000
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 Land
Resources (DLR). Compliance with the DLR issued permit is considered a requirement
of this general permit. Any deviation from the DLR issued 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 DWQ
inspectors. A signed copy of the issued 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 the Division of Land Resources in accordance
with NC G.S. Chapter 74, Article 7, it shall no longer be subject to this general permit.
Stormwater Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, 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. All stormwater controls shall be
inspected. All inspections are to be documented with a written record of repairs.
BMPs shall be inspected by or under the direction of the permittee at least once
every seven calendar days and within 24 hours after any storm event that results in
a discharge, unless the site is inactive.
Reduced Inspections for inactive mines: For inactive mines that have obtained an
"Inactive Renewal" Mining Permit from DLR, BMPs must be inspected at least
once every month, and within 24 hours of any storm event of 0.5 inches or more.
For mines where active mining has suspended temporarily, but the mine maintains
an active Mining Permit from DLR, the permittee must certify to DWQ that all
portions of the site where clearing, grading, and/or excavation activities have
temporarily ceased have been stabilized with vegetation, and may then conduct
BMP inspections within 24 hours of any storm event that results in a discharge (no
weekly minimum). The permittee must send certification to the DWQ Regional
Office of "inactive" status and may be subject to an inspection for verification. The
permittee must also notify the Regional Office upon resuming mining activities.
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% permitted volume. If visible sedimentation is leaving the property, corrective
Part III Page 2 of 16 Pages

Permit No. NCG020000
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 III. D) on a semi-annual schedule. A log of all sampling data, including
activities taken to implement SMPs 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; 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), and 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 (S) years.
4. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (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 plan. A responsible person
shall be on -site at all times during facility operations that have the 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.
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,
Part III Page 3 of 16 Pages

Permit No. NCG020000
disposal areas, process areas, loading and unloading areas, and haul roads), where not
already addressed under another element of this Plan. Schedules for inspections,
maintenance, and housekeeping, and documentation that these program elements are being
implemented, 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. Facility personnel (or team)
responsible for implementing the training shall be identified, and their annual training shall
be documented by the signature of each employee trained. Additional required training
items include: used oil management, spent solvent management, disposal of spent
abrasives, disposal of vessel wastewaters, fueling procedures, sanding, painting and blasting
procedures, and used battery management.
7. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be documented
and position assignments provided.
Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance that has a significant effect on the potential
for the discharge of pollutants to surface waters. All aspects of the Stormwater Pollution
Prevention Plan shall be reviewed and updated on an annual basis. The annual update
shall include an updated list of significant spills or leaks of pollutants for the previous three
(3) years, or the notation that no spills have occurred. The annual update shall include
written re -certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. Each annual update shall include a documented re-evaluation
of the effectiveness of the BMPs listed in the BMP Summary of the Stormwater Management
Plan. The Director may notify the permittee when the Plan 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 Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with Part
VI, Standard Conditions, Section B, Paragraph 5) to the Director that the changes have been
made.
9. Plan Implementation. The permittee shall implement the Plan and all appropriate BMPs
to ensure that contaminants do not enter surface waters via stormwater that comes in
contact with any unstabilized overburden, raw materials, intermediate products, finished
products, byproducts or waste products located on the site covered by this permit.
Implementation of the Plan 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 years and made available to the Director or the Director's authorized
representative immediately upon request.
SECTION B: STORMWATER DISCHARGES: ANALYTICAL MONITORING REQUIREMENTS
Stormwater discharges are defined as stormwater 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
Part III Page 4 of 16 Pages

Permit No. NCG020000
and process areas. Analytical monitoring for stormwater discharges shall be performed for
parameters as specified in Tables 1 through 3. All analytical monitoring shall be performed
during a representative storm event as defined below.
Monitoring Exemption
Analytical monitoring is not required for any basin or pond designed to contain the 25-year, 24-
hour storm (see Part VI I, 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.

2. Grab samples shall be collected within the first 30 minutes of discharge. For sites where multiple outfalls
are separated by distances that preclude collection within 30 minutes of each discharge event is not
feasible, begin collection procedures within 30 minutes and continue until all outfalls with discharges are
sampled. Documentation explaining why it was not possible to take samples within the first 30 minutes
must be kept in the SHE
3. Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless
representative outfall status (ROS) has been granted and documented by the Division of Water Quality. A
copy of the letter granting ROS shall be kept on site.
4. Turbidity may be monitored at the Stormwater Discharge Outfall. Alternativeiy, the permittee may
choose to monitor turbidity in the receiving water, directly upstream and downstream of the stormwater
discharge outfall(s).
5. For each sampled representative storm event the total precipitation must be recorded. An on -site rain
gauge or local rain gauge reading must be recorded.
6. Total flow shall be: (a) measured continuously, or (b) calculated based on the amount of area draining to
the outfall, the amount of impervious area, and the total amount of rainfall, or (c) estimated by the
measurement of flow at 20 minute intervals during the rainfall event. Total rainfall precipitation and
duration of the rainfall event refers to the representative storm event sampled.
All analytical monitoring shall be performed during a representative storm event at each
stormwater discharge outfall (SDO]. The permit allows the permittee to monitor turbidity at the
SDO or up- and downstream of the SDO; however, the permittee should consider regular turbidity
sampling up- and downstream of the discharge(s) when feasible to ensure compliance with water
quality standards.
Part III Page 5 of 16 Pages

Permit No. NCG020000
A representative storm event for the purposes of this General Permit is a storm event that
measures greater than 0.1 inches of rainfall. The time between this storm event and the previous
storm event measuring greater than 0.1 inches must be at least 48 hours. One storm event may
have a time period within it that has no precipitation. This time period may last up to 10 hours, For
example, if it rains but stops before producing any collectable discharge, a sample may be collected if
the next rain producing a discharge begins within 10 hours.
The permittee shall complete the analytical samplings in accordance with the schedule specified in
Table 2. A minimum of 60 days must separate each sample event unless monthly monitoring
has been instituted Under a Tier 2 response. Failure to comply with semi-annual monitoring in
accordance with permit t rm f r an six-month monitoring Period immediately triggers monthly
monitoring for the remaining permit term unless adverse weather conditions prevent sample
collection during the sample collection period. Inability to sample due to adverse weather
conditions must be documented in the SPPP with date, time and written narrative (see Adverse
Weather in Definitions) and reported on the Annual Summary DMR.

SECTION E: WASTEWATER DISCHARGES: EFFLUENT LIMITATIONS AND MONITORING
REQUIREMENTS FOR MINE DEWATERING WASTEWATER & PROCESS
WASTEWATER
1. MINE DEWATERING WASTEWATER
Mine dewatering requirements apply to all mines that dewater from pits including quarries, clay
brick, sand & gravel, borrow pits, and refractory mining, as well as mines with similar discharges.
Note that for Construction Sand and Gravel or Industrial Sand mines, "mine dewatering" -
wastewater includes wet pit overflows caused solely by direct rainfall and groundwater seepage.
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 activities that have the potential to drain wetlands
or other surface waters must have secured and implemented a Pumping Operation and
Monitoring (O&M) Plan approved by the Division. Pumping 0&M Plans shall include, but are not
limited to:
• Groundwater monitoring strategies to demonstrate the effect of pumping.
• Detailed plans to maintain the surrounding hydrology that protects the affected streams and
wetlands and the respective monitoring to demonstrate compliance.
• 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 Pumping O&M Plan may be
required prior to coverage under this general permit.
Analytical monitoring of mine dewatering wastewater shall be performed as specified below in
Table 7. For each parameter, an effluent limitation is contained in Table 8. An exceedence of any
of these limitations is a violation of the permit conditions and may be subject to enforcement action
as specified in Part 1V, Section A.2 of this permit.
Part III Page 11 of 16 Pages

Permit No. NCG020000
Mine Dewatering Treatment System ATC Requirement:
Engineered erosion and sedimentation control (E&SC) structures that sufficiently treat mine
dewatering wastewater so that permit effluent limits are met and water quality is protected, do not
require an Authorization to Construct (AtC) and may operate in accordance with Part II, Sections A
and B. Any additional treatment devices (other than erosion and sediment control
structures) needed to meet permit limits and conditions are subject to Authorization to
Construct (AtC) requirements.
2. PROCESS_ WASTEWATER
Process wastewater includes, but may not be limited to, the water involved in the slurry transport,
washing, 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.
A) Overflow From Non -Closed Loop Recycle Systems
A "closed -loop" system is a wastewater recycle system where the only other water that may be
added is either make-up water or precipitation that falls directly into the system. "Closed -loop"
systems must operate at or below two feet of freeboard and must be designed to exclude
stormwater runoff from draining into it. Non -closed -loop recycle systems may recycle water,
but do not meet the above design criteria.
During the period beginning on the effective date of the permit and lasting until expiration, the
permittee is authorized to discharge overflow from the process recycle wastewater systems that are
not designed as closed -loop recycle systems.
Analytical monitoring of overflow from process recycle wastewater systems that are not designed as
closed -loop recycle systems shall be performed as specified below in Table 7. For each parameter,
an effluent limitation is contained in Table 8. For the purposes of this permit, overflow refers to a
discharge of process wastewater as a result of a precipitation event.
Nan -Closed -Loop Recycle System ATC Requirement:
Non -closed loop recycle systems do not meet the requirements for closed -loop recycle systems and
are not designed and operated with two feet of freeboard. Authorization to construct and operate
requirements (Part 11, Sections A and B) are applicable to non -closed -loop recycle systems.
B) Other Treated Process Wastewater Discharges
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.
Treatment may involve conveyance through erosion and sedimentation control (E&SC] structures
and/or other engineered treatment systems.
Analytical monitoring of process wastewater shall be performed as specified below in Table 7. For
each parameter, an effluent limitation is contained in Table B. An exceedence of any of these
limitations will result in a violation of the permit conditions and may be subject to enforcement
action as specified in Part IV, Section A.2 of this permit.

Permit Number - NCG020157
County - Orange
Dear Mr. Huskins:
On February 17, 2009, Autumn Hoban, of the Division of Water Quality (DWQ), Raleigh Regional Office,
performed a stormwater compliance evaluation inspection of the quarry. Your assistance and cooperation was
helpful and appreciated. inspection findings are listed below.
'industry na d Site:l]escription�
Resco Products, Inc. mines sand, rock, and refractory materials at the Hillsborough quarry. Stormwater runoff
and process wastewater generated at such facilities is regulated by General Permit NCG020000. DWQ has
therefore issued Resco Products, inc. certificate of coverage, NCG020157, which became effective on January
19, 2005 and expires on December 31, 2009.

The facility is mostly a dry plant, but approximately 25% of mining material is washed on -site. Stormwater and
process water is directed to a settling pond. Some of the water is recycled. The plant has an intake for
receiving water from the Eno River, and utilizes the water as needed, and then discharges back to the Eno
River. The original stream was re -directed around the plant many years ago and a trough carries the water from
the Eno River through the mine site property to the permitted discharge. The intake is located after the
discharge location, thereby, creating a semi -dosed re -circulating system, when water is being withdrawn for use
at the facility.
The settling pond overflows to the discharge trough and eventually to the Eno River. The pond is cleaned
periodically and spoils are placed in the mine. The spoils runoff water and water within the mine can be pumped
through 2 vertical drains to a pond, and then filter through a rock dam. Photos are attached, the pond is
currently dry, and it appears that sheet flow is likely upon an overflow as designed.

The facility keeps good records and was in compliance with the permit requirements.
The facility has one permitted outfall and the sampling is done at the trough before the outfall, since it is difficult
to reach the actual discharge pipe. The monitoring records on -site showed the most recent sampling was
completed 6/19/2008 and 9/11/2008 and the results were good with no water quality issues.
The pit was sampled the day of the inspection to identify the characteristics of the wastewater, The results are
attached. This information was gathered to assist with permit renewals.
Waste oil and diesel fuel are stored on -site and meet secondary containment requirements. No spills were
observed on -site during the inspection. Fifty-five gallon drums were covered. Bauxite is brought in and stored
on -site.
It is our goal to insure the quality of the surface waters of this State.
Please review the attached report. If you or your staff have any questions, do not hesitate to contact Autumn
Hoban at 919-791-4200.
Sincerely,
Autumn Hoban

inspection Summary:
The facility was in compliance with the requirements of the permit.
Sampling was conducted at the mine pit in order to characterize the wastewater. No pit water was discharging the day of
the inspection and the basin that the pit water would Flow to when pumped has reportedly been dry since the 2007
drought. This location is not an NPDES Outfall, because the basin has a rock filter dam that delivers sheet flow to a
wooded area above the Eno River. The sample results revealed some metals concerns, in the event that during a heavy
storm event, flow could reach the Eno River. Since this outfall is not a permitted outfall, there are no requirements for
inspection. The sample results are attached.
It is recommended that the permittee understand the Water Quality Action Levels for the Eno River and ensure that no
discharge from the facility would exceed action levels or water quality standards for the Eno River.

PART 1 INTRODUCTION
SECTION A: GENERAL PERMIT COVERAGE
All persons desiring to have facilities covered by this General Permit must register with the
Division of Water Quality (DWQ) 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 process
wastewater that has a point source discharge to the surface waters of the state.
This General Permit covers mining and quarrying of nonmetallic minerals (except fuels)
including borrow pits that would not be covered under the statewide DOT stormwatcr 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.
Facilities submitting NOls for coverage under this permit, prior to establishment or approval of a
Total Maximum Daily Load (TMDL) for a priori ty.pollutant(s) for stormwater discharges (i.e.
wet weather flows), may be covered under this permit during its term. For such facilities
continued coverage under the reissuance of this permit is subject to the facility demonstrating
that it does not have a reasonable potential to violate applicable water quality standards for such
pollutants due to the stormwater discharge(s). For facilities that do have a reasonable potential
for violation of applicable water quality standards due to the stormwater discharge(s) the facility
shall apply for an individual permit 180 days prior to the expiration of this general permit. Once
the individual permit is issued and becomes effective the facility will no longer have coverage
tinder the general permit. A list of approved TMDLs for the state of North Carolina can be found
at littp://ii2o.enr.state.nc.us/tmdl/Gcneral_TMDLs.htm.

PART III MONITORING, CONTROLS, AND LIMITATIONS FOR
0 PERMITTED DISCHARGES
SECTION A: STORMWATER BEST MANAGEMENT PRACTICES (BMPS) PLAN
The permittee shall implement stormwater BMPs to ensure that contaminants do not enter
surface waters via stormwater that comes in contact with any unstabilized overburden,
raw materials, intermediate products, finished products, byproducts or waste products
located on the site covered by this permit. A BMP Plan shall be developed in accordance
with the requirements of this section. The BMP Plan requirement, or portions of the plan
requirement, may be met by utilizing appropriate requirements in other documented plans
specific to the permitted facility.
Management of Stormwater Runoff and Runon. The permittee shall maintain stormwatcr
BMPs for land disturbance areas and outside process areas. 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
stormwatcr 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).
3. BMP Controls Inspection and Maintenance. All stormwater BMPs shall be inspected by
or under the direction of the permittee at least once every seven calendar days and within
24 hours after any storm event that results in a discharge. The BMPs implemented shall
be operated and maintained so that they are cleaned out when the sediment storage
capacity has been reduced by 50%. if any visible sedimentation is leaving the property,
corrective action shall be taken to reduce the discharge of sediments. Visible
sedimentation found offsite shall be recorded with a brief explanation as to the measures
taken to prevent future releases as well as any measures taken to remove the sediment that
left the site. Ali other stormwater specific controls (e.g. oil /water separators) shall be
inspected and qualitatively monitored (as per Part III.B.3) on a semiannual schedule, once
in the fall (September -November) and once during the spring (April -June). A log of
sampling data and of activities taken to implement BMPs associated with the vehicle
maintenance activities shall be maintained and incorporated into the BMP Plan and kept
onsite for the duration of the permit term and made available to the Director upon request.
4. 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 Land
Resources. Compliance with the issued permit is considered a requirement of this
general permit. Any deviation from the issued permit, or amendments to the issued
permit, that impacts water qualitx shall constitute a violation of the tenns and conditions
of this general permit. A signed copy of the issued 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 the Division of Band Resources in
Part III Page 1 of 9

•
Permit No. NCG020000
accordance with NCGS Chapter 74, Article 7, it shall no longer be subject to this general
permit.
5. Preventive Maintenance Inspections and Good Housekeeping Practices. Equipment
utilized during mining activity on a site must be operated and maintained in such a
manner as to prevent potential or actual pollution of the surface water or ground waters of
the state. Fuels, lubricants, coolants, and hydraulic fluids, or any other petroleum
products, shall not be discharged on the ground or into surface waters. Spent fluids shall
be disposed of in a manner so as not to enter the surface waters or ground waters of the
state and in accordance with applicable federal disposal regulations. Any spilled fluids
shall be cleaned up to the maximum extent practicable and disposed of in a manner that
does not allow their entry into the surface waters or ground waters of the state.
Secondary Containment. The permittce shall provide secondary containment for bulk
storage of liquid materials, storage of Section 313 of Title III of the Superfund
Amendments and Reauthorization Act (SARA) water priority chemicals, or storage of
hazardous liquids substances to prevent leaks and spills from contaminating stormwater
runoff. If the secondary containment devices are connected directly to stormwater
conveyance systems, the connection shall be controlled by manually activated valves or
other similar devices (which shall be secured with a locking mechanism) and 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 the material stored within the containment area.
SECTION B: ANALYTICAL AND QUALITATIVE MONITORING REQUIREMENTS
FOR DISCHARGES COMPOSED ENTIRELY OF STORMWATER
Analytical monitoring for stormwater discharges shall be performed for parameters as specified
in Tables 1 through 4. All analytical monitoring shall be performed during a representative storm
event as defined in Part VII. For each parameter, the arithmetic mean of all analytical sampling
results collected during the term of the permit may be calculated for each individual outfall and
compared to the cut-off concentrations listed in Tables 2 and 4. If the arithmetic mean is less
than the specified cut-off concentration for a given parameter, the facility is not required to
continue annual monitoring for that parameter (at that outfall) until the last year of the permit
unless a significant change in facility operations or configuration occurs. If a cut-off
concentration results in discontinued analytical monitoring at an individual discharge outfall, the
permittee is required to maintain facility operations that ensure the continuation of stormwater
runoff quality. The 1erinittee must perform analytical sampling during the first and last year of
the permit terra regardless of cut-off concentration conditions.
In situations where stormwater runoff is controlled by some type basin or retentionldctentiOil
pond, the following provisions are applicable for sample collection for analytical monitoring:
• Analytical monitoring for stormwater discharges from a basin or other similar control
structures must be performed within the first 30 minutes of discharge.
Part III Page 2 of 9

E
Wi ilia ON►WO)"ZIN111I
• Analytical monitoring for a basin /pond designed to contain the 10-year design storm (see
Part V11, Definitions) without discharging is not required. Qualitative monitoring for color,
foam, outfall staining, visible sheen and dry weather flow is the only monitoring requirement.
• Analytical and qualitative monitoring arc not required for a basin/pond designed to contain
the 25-ycar, 24-hour storm (see Part VII, Definitions) without discharging. A basin/ pond
meeting this provision is considered a non -discharging stormwatcr control.
Analytical Monitoring for Stormwater Discharges from Land Disturbance and -
Process Areas.
