Permit No. NCS000040
Charlotte Pipe and Foundry Company
Mecklenburg County
Dear Mr. Waggoner:
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please review the draft
carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from the facility's current permit:
1. You are required to collect analytical and qualitative monitoring samples during "measurable storm
events' as defined in Part II, Section B. This term is different from the "representative storm event" in
earlier permits.
2. Requirements for the Stormwater Pollution Plan (SPPP) have been updated in Part 11, Section A.
3. Monitoring requirements in the draft permit have changed from the previous permit. Monitoring is
proposed for Total Suspended Solids (TSS), Chemical Oxygen Demand (COD), Total Copper (Cu), Total Lead
(Pb), Total Zinc (Zn) and pH. Based on monitoring results reported as well as the potential pollutants at
your facility the Division has determined that these parameters are appropriate for assessing potential
impacts from your discharge. Monitoring results from the previous permit cycle for Oil & Grease,
Chromium (Cr), Total Kjeldahl Nitrogen (TKN), Nickle (Ni) and Phenols have been consistently below the
benchmark values. The draft permit proposes to remove these parameters from the permit. Comments
from our regional staff or other information may result in maintaining these parameters or adding other
parameters if it is apparent that your activities in some way have the potential to release them through
stormwater runoff.
Please note that for a number of the metals parameters the benchmark values have increased since the last
permit. The table below shows the changes.

benchmark exceedance is not a permit violation; however, the permittee must respond to exceedances. The
draft permit has modified the tiered response process for benchmark exceedances consistent with
other permits in our program. Please become familiar with the tiered process as proper response under the
tiers maybe enforceable items under your permit. Response to the tiered process may include review of
onsite conditions, installation of BMPs or requirements for more frequent monitoring.
4. Vehicle maintenance (Tables 4 & 5) monitoring parameters have been revised. Non -Polar Oil & Grease
[EPA Method 1664 (SGT-HEM)] replaces Oil & Grease/TPH. The benchmark for Non -polar Oil & Grease
using this method is 15 mg/L. This requirement appears in all individual stormwater permits; however, it
only applies to facilities that perform onsite vehicle maintenance activities. If the facility begins vehicle
maintenance during the permit cycle, the requirements shall apply. Also, pH monitoring is no longer
required for discharges only associated with vehicle maintenance activities.
The vehicle maintenance language in the permit has also been modified to clarify that these activities
include not just vehicles, but also other similar equipment maintenance activities that may be exposed to
stormwater. This has always been the Division's implementation of this requirement, but hopefully the
adjusted language is a little clearer about this process.
S. Language has been added under Part II Section D to address potential responses to qualitative
monitoring issues.
6. A new section on Special Conditions has been added in Part 11, Section E to comply with federal regulations
requiring electronic submittal of discharge monitoring reports. Our electronic submittal process is not
available for use at this time, but we will continue to provide feedback on when this process will be
available.
7. Civil and administrative penalty amounts have been updated to reflect current federal law in Part III,
Section A, 2(b) and (g).
8. The definition of Bulk Storage oftiquid Materials was revised in Part IV Definitions to omit the language
"located in close proximity to each other" as it applies to multiple above ground storage containers having a
combined storage of 1,320 gallons.
9. To address workload issues in the Stormwater Program we are working to have similar numbers of
individual permits for renewal over each of the next five years. In order to accomplish this some of our
permit renewals will be issued for time periods shorter than the usual five year cycle. Your permit renewal
is proposed to expire in 2021.
Please review the draft permit and submit any comments to me no later than 30 days following your receipt of
the draft. Comments maybe emailed tome at bradley.bennett(i)ncdenr gov or mailed to my attention at NC
DEMLR, Stormwater Permitting Program, 1612 Mail Service Center, Raleigh, NC 27699-1612. With this
notification the Division will solicit comment on this draft by publishing a notice in a local newspaper.
Following the 30 day public comment period, the Division will review comments and take appropriate action
prior to issuance of the final permit.
If you have any questions, please email me or call me at [phone].
Sincerely,

Permit No. NCS000040 DRAFT
PART I INTRODUCTION
SECTION A: INDIVIDUAL PERMIT COVERAGE
During the period beginning on the effective date of the permit and lasting until expiration,
the permittee is authorized to discharge stormwater associated with industrial activity.
Such discharges shall be controlled, limited and monitored as specified in this permit.
If industrial materials and activities are not exposed to precipitation or runoff as described
in 40 CFR §122.26(g), the facility may qualify for a No Exposure Exclusion from NPDES
stormwater discharge permit requirements. Any owner or operator wishing to obtain a No
Exposure Exclusion must submit a No Exposure Certification Notice of Intent (NOI) form to
the Division; must receive approval by the Division; must maintain no exposure conditions
unless authorized to discharge under a valid NPDES stormwater permit; and must recertify
the No Exposure Exclusion annually.
SECTION B: PERMITTED ACTIVITIES
Until this permit expires or is modified or revoked, the permittee is authorized to discharge
stormwater to the surface waters of North Carolina or separate storm sewer system that
has been adequately treated and managed in accordance with the terms and conditions of
this permit. All stormwater 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. The stormwater discharges allowed by this permit shall not cause or contribute
to violations of Water Quality Standards.
This permit does not relieve the permittee from responsibility for compliance with any
other applicable federal, state, or local law, rule, standard, ordinance, order, judgment, or
decree.

PART II MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
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 is public information in accordance with Part 111, Standard
Conditions, Section E, paragraph 3 of this 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 waters to which the stormwater outfalls
discharge, 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 points of stormwater discharge associated with industrial
activity. The general location map (or alternatively the site map) shall identify
whether any receiving waters are 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 parameters 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 and
finished grade; 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); and impervious surfaces. The site map must
indicate the percentage of each drainage area that is impervious, and the site map
must include a graphic scale indication and north arrow.
(d) A list of significant spills or leaks of pollutants during the previous three (3) years
and any corrective actions taken to mitigate spill impacts.

Permit No. NCS000040 DRAFT
(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. The certification statement will be signed in accordance with the
requirements found in Part 111, Standard Conditions, Section B, Paragraph 3.
Stormwater Management Strategy. The Stormwater Management Strategy shall
contain a narrative description of the materials management practices employed which
control or minimize the stormwater exposure of significant materials, including
structural and nonstructural measures. The Stormwater Management Strategy, at a
minimum, shall incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to rainfall and run-on flows. Wherever practical, the
permittee shall prevent exposure of all storage areas, material handling operations,
and manufacturing or fueling operations. In areas where elimination of exposure is
not practical, this review shall document the feasibility of diverting the stormwater
run-on away from areas of potential contamination.
(b) 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). 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 facilities subject to a federal oil Spill
Prevention, Control, and Countermeasure Plan (SPCC), any portion of the SPCC Plan
fully compliant with the requirements of this permit may be used to demonstrate
compliance with this permit. The Division may allow exceptions to secondary
containment requirements for mobile refuelers, as with the exemption provided by
amendments to federal SPCC regulations, as long as appropriate spill containment
and/or diversionary structures or equipment is used to prevent discharge to surface
waters. Exceptions do not apply to refuelers or other mobile tankage used primarily
as bulk liquid material storage in a fixed location in place of stationary containers.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMPs) shall be provided. The installation and implementation of BMPs

Permit No. NCS000040 DRAFT
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and on data collected
through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMP Summary shall be reviewed and updated annually.
3. 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 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
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.
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance and good housekeeping program shall be developed and implemented.
The program shall address all stormwater control systems (if applicable), stormwater
discharge outfalls, all on -site and adjacent surface waters and wetlands, industrial
activity areas (including material storage areas, material handling areas, disposal areas,
process areas, loading and unloading areas, and haul roads), all drainage features and
structures, and existing structural BMPs. The program shall establish schedules of
inspections, maintenance, and housekeeping activities of stormwater control systems,
as well as facility equipment, facility areas, and facility systems that present a potential
for stormwater exposure or stormwater pollution where not already addressed under
another element of the SPPP. Inspection of material handling areas and regular
cleaning schedules of these areas shall be incorporated into the program. Timely
compliance with the established schedules for inspections, maintenance, and
housekeeping shall be recorded and maintained in the SPPP.
S. Facility Inspections. Inspections of the facility and all stormwater systems shall occur
as part of the Preventative Maintenance and Good Housekeeping Program at a
minimum on a semi-annual schedule, once during the first half of the year (January to
June), and once during the second half (July to December), with at least 60 days
separating inspection dates (unless performed more frequently than semi-annually).
These facility inspections are different from, and in addition to, the stormwater
discharge characteristic monitoring at the outfalls required in Part Il B, C, and D of this
permit.
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. The facility

Permit No. NCS000040 DRAFT
personnel responsible for implementing the training shall be identified, and their
annual training shall be documented by the signature of each employee trained.
7. Responsible Party. The SPPP shall identify a specific position or positions responsible
for the overall coordination, development, implementation, and revision of the SPPP.
Responsibilities for all components of the SPPP shall be documented and position
assignments provided.
SPPP Amendment and Annual Update. 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. All aspects of
the SPPP shall be reviewed and updated on an annual basis. The annual update
shall include:
(a) an updated list ofsignificant 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 (BMPSummary element of the Stormwater Management Strategy).
(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) form, available from the Stormwater Permitting
Program's website (See: https://deg.nc.gov/about/divisions/ener�v-mineral-land-
resources/n pdes-stormwater-individual).
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 111, Standard Conditions, Section B, Paragraph 3) 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.
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.

Permit No. NCS000040 DRAFT
SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1.
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 is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DEMLR Regional Engineer. See Definitions.
The permittee shall compare monitoring results to the benchmark values in Table 1.
Exceedances of benchmark values require the permittee to increase monitoring, increase
management actions, increase record keeping, and/or install stormwater Best Management
Practices (BM Ps) in a tiered program. See below the descriptions of Tier One, Tier Two, and
Tier Three response actions below. In the event that the Division releases the permittee from
continued monthly monitoring and reporting under Tier Two or Tier Three, the Division's
release letter may remain in effect through subsequent reissuance of this permit, unless the
release letter provides for other conditions or duration.
The benchmark values in Table 1 are not permit limits but should be used as guidelines for
implementation of the permittee's SPPP. An exceedance of a stormwater benchmark value
is not a permit violation; however, failure to respond to the exceedance as outlined in this
permit is a violation of permit conditions.
Please note that the parameters in the last two rows in Table 1 (no -polar oil and grease and
new motor oil usage) are only required for outfalls that discharge runoff from vehicle or
equipment maintenance areas in which more than 55 gallons of new motor oil and/or
hydraulic oil per month is used when averaged over the calendar year.

1 Measurement Frequency: Twice per year (unless other provisions of this permit prompt 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 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. When physical separation between
outfalls prevents collecting all samples within the first 30 minutes, sampling shall begin 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.
4 For each sampled measurable storm event, the total precipitation must be recorded. An on -site rain gauge
is required. Where isolated sites are unmanned for extended periods of time, a local rain gauge reading
may be substituted for an on -site reading.
S This parameter is only required for outfalls that discharge runoff from vehicle / equipment maintenance
areas in which more than SS gallons of new motor oil per month is used when averaged over the
calendar year.
The permittee shall complete the analytical samplings in accordance with the schedule
specified below in Table 2, unless adverse weather conditions prevent sample collection
(see Adverse Weather in Definitions). Sampling is not required outside of the facility's
normal operating hours. A minimum of 60 days must separate Period 1 and Period 2
sample dates, unless monthly monitoring has been instituted under a "Tier Two"
response. Inability to sample because of adverse weather conditions must be documented
in the SPPP and recorded on the DMR. The permittee must report the results from each
sample taken within the monitoring period (see Part Ill, Section E). 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.

1 Maintain semi-annual monitoring until either another permit is issued for this facility or until this
permit is revoked or rescinded. The permittee must submit an application for renewal of coverage
before the submittal deadline (180 days before expiration) to be considered for renewed coverage
under the permit. The permittee must continue analytical monitoring throughout the permit
renewal process, even if a renewal permit is not issued until after expiration of this permit.
2 If no discharge occurs during the sampling period, the permittee must submit a monitoring report
indicating "No Flow" or "No Discharge' within 30 days of the end of the sampling period.
3 Monitoring periods remain consistent through the permit term and through the renewal process.
Failure to monitor semi-annually per permit terms may result in the Division requiring
monthly monitoring for all parameters for a specified time period. "No discharge" from an
outfall during a monitoring period does not constitute failure to monitor, as long as it is
properly recorded and reported.

Permit No. NCS000040 DRAFT
If: The first valid sampling results are above a benchmark value, or outside of the benchmark range, for any
parameter at any outfall;
Then: The permittee shall:
1. Conduct a stormwater management inspection of the facility within two weeks of receiving sampling
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, and/or to bring concentrations
within the benchmark range.
4. Implement the selected feasible actions within two months of the inspection.
S. Record each instance of a Tier One response in the SPPP. Include the date and value of the benchmark
exceedence, the inspection date, the personnel conducting the inspection, the selected actions, and the
date the selected actions were implemented.
6. Note: Benchmark exceedances for a different parameter separately trigger a tiered response.
Tier Two —
If: The first valid sampling results from two consecutive monitoring periods (omitting periods with no
discharge) are above the benchmark values, or outside of the benchmark range, for any specific parameter at
Then: The permittee shall:
1. Repeat all the required actions outlined above in Tier One.
2. Immediately institute monthly monitoring and reporting for all parameters. The permittee shall conduct
monthly monitoring 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 or within benchmark range.
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, after two consecutive exceedances, exercise the
option of contacting the DEMLR Regional Engineer as provided below in Tier Three. The Regional
Engineer may direct the response actions on the part of the permittee as provided in Tier Three,
including reduced or additional sampling parameters or frequency.
5. Maintain a record of the Tier Two response in the SPPP.
6. Continue Tier Two response obligations throughout the permit renewal process.
If: The valid sampling results required for the permit monitoring periods exceed the benchmark value, or
are outside the benchmark range, for any specific parameter at any specific outfall on four occasions, the
permittee shall notify the DEMLR Regional Engineer in writing within 30 days of receipt of the fourth
Then: The Division may but is not limited to:
• require that the permittee revise, increase, or decrease the monitoring and reporting frequency for
some or all of the parameters herein;
• require sampling of additional or substitute parameters;
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures;
• require the permittee to perform upstream and downstream monitoring to characterize impacts on
receiving waters; or
• require the permittee implement site modifications to qualify for a No Exposure Exclusion;
• require the permittee to continue Tier Three obligations through the permit renewal process.

This site discharges to impaired waters experiencing problems with Copper, Lead and Zinc.
If further actions, including the development ofa Total Maximum Daily Load (TMDL), are
required for this segment of Irwin Creek, the Division will consider your monitoring results in
determining whether additional BMPs are needed to control the pollutant of concern to the
maximum extent practicable.
If additional BMPs are needed to achieve the required level of control, the permittee will be
required to (1) develop a strategy for implementing appropriate BMPs, and (2) submit a
timetable for incorporation of those BMPs into the Stormwater Pollution Prevention Plan.
SECTION C: QUALITATIVE MONITORING REQUIREMENTS
The purpose of qualitative monitoring is to evaluate the effectiveness of the Stormwater
Pollution Prevention Plan (SPPP) and identify new potential 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 regardless of
representative outfall status. Qualitative monitoring shall be performed semi-annually
during required analytical monitoring events (unless the permittee is required to perform
further qualitative monitoring per the Qualitative Monitoring Response, below). Inability
to monitor because of adverse weather conditions must be documented in the SPPP and
recorded on the Qualitative Monitoring Report form (see Adverse Weather in Definitions).
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 during a meast reable storm event unless other provisions of this
permit prompt monthly monitoring. See Table 2 for schedule of monitoring periods. The permittee must
continue qualitative monitoring throughout the permit renewal process until a new permit is issued.
2 Monitoring Location: Qualitative monitoring shall be performed at each stormwater discharge outfall
(SDO) regardless of representative outfall status.
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 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 Stormwater Pollution Prevention Plan.
Qualitative monitoring is for the purposes of evaluating SPPP effectiveness, identifying new
potential 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, the
Division may but is not limited to:
• require that the permittee revise, increase, or decrease the monitoring frequency for some
or all parameters (analytical or qualitative)
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures;
• require the permittee to perform upstream and downstream monitoring to characterize
impacts on receiving waters; or
• require the permittee implement site modifications to qualify for a No Exposure Exclusion.
SECTION D: SPECIAL CONDITIONS

Effective December 21, 2016 or when the agency's electronic reporting system is able
to accept NPDES stormwater permit monitoring data, the permittee shall report
discharge monitoring data electronically using the NC DWR's Electronic Discharge
Monitoring Report (eDMR) internet application. NC DEMLR will notify permittees
when eDMR is ready to accept stormwater monitoring data.
Monitoring results obtained during the previous month(s) shall be summarized for each
month and submitted electronically using eDMR. The eDMR system allows permitted
facilities to enter monitoring data and submit DMRs electronically using the internet.
Until such time that the state's eDMR application is compliant with EPA's Cross -Media
Electronic Reporting Regulation (CROMERR), permittees will be required to submit all
discharge monitoring data to the state electronically using eDMR and also will be
required to complete the eDMR submission by printing, signing, and submitting one
signed original and a copy of the computer printed eDMR to the following address:
NC DEQ / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central Files

If a permittee is unable to use the eDMR system due to a demonstrated hardship or due
to the facility being physically located in an area where less than 10 percent of the
households have broadband access, then a temporary waiver from the NPDES
electronic reporting requirements may be granted and discharge monitoring data may
be submitted on paper DMR forms or alternative forms approved by the Director.
Duplicate signed copies shall be submitted to the mailing address above. See "How to
Request a Waiver from Electronic Reporting" section below.
Regardless of the submission method, the first DMR is due no later than 30 days from
the date the facility receives the sampling results from the laboratory.
2. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To
obtain an electronic reporting waiver, a permittee must first submit an electronic
reporting waiver request to the Division. Requests for temporary electronic reporting
waivers must be submitted in writing to the Division for written approval at least sixty
(60) days prior to the date the facility would be required under this permit to begin
submitting monitoring data and reports. The duration of a temporary waiver shall not
exceed 5 years and shall thereupon expire. At such time, monitoring data and reports
shall be submitted electronically to the Division unless the permittee re -applies for and
is granted a new temporary electronic reporting waiver by the Division. Approved
electronic reporting waivers are not transferrable. Only permittees with an approved

planned changes or anticipated noncompliance does not stay any permit condition [40 CFR
122.41(f)].
6. Annual Administering and Compliance Monitoring Fee Requirements
The permittee must pay the administering and compliance monitoring fee within 30 (thirty) days
after being billed by the Division. Failure to pay the fee in timely manner in accordance with 15A
NCAC 2H .0105(b)(2) may cause the Division to initiate action to revoke the permit.
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
permit [40 CFR 122.41(c)].
3. Bypassing of Stormwater Control Facilities
Bypass is prohibited and the Director 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
18

Permit No. NCS000040 DRAFT
c. The permittee submitted notices as required under, Part 111, Section E of this permit.

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 permit discharge
requirements, then the most sensitive (method with the lowest possible detection and reporting
level) approved method must be used.
S. 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 sampling requirements may be performed at a reduced
number of outfalls.

storage capacity of 2,018ft3, or approximately 15,097 gallons. Spilled material
collected within the containment area is removed and disposed of in accordance
with applicable regulations.
• Two 6,000-gallon asphalt emulsion storage tanks are located on an asphalt -paved
surface west of the Water Test building. The tanks are provided with secondary
containment in the form of an open -top containment area concrete sump. The
sump is approximately 15 feet by 37 feet by 3 feet, which equates to an
approximate storage capacity of 1,665 W, or approximately 12,455 gallons.
Spilled material collected within the containment area is removed and disposed
of in accordance with applicable regulations.
• A 6,000-gallon hot dip storage tank is located on an asphalt -paved surface west
of the 5-Foot Water Test building. The tank is provided with secondary
containment in the form of an open -top containment area concrete sump. The
sump is approximately 15 feet by 37 feet by 3 feet, which equates to an
approximate storage capacity of 1,665 ft3, or approximately 12,455 gallons.
Spilled material collected within the containment area is removed and disposed
of in accordance with applicable regulations.
• One 50-ton sand silo is located west of the main production building. In
addition, one feldspar silo and one silica flour silo is located south of the waste
treatment building. The silos are not equipped with secondary containment.
However, since the contents are not liquid, spilled material will be easily cleaned
up and should not impact stormwater.

One 550-gallon used oil storage tank is located on an asphalt -paved surface south
of the Oil House. The tank is provided with secondary containment in the form
of metal walls. The containment area is approximately 4 feet X 6 feet X 2 feet,
which equates to an approximate storage capacity of 48 W, or approximately 359
gallons. Spilled material collected within the containment area is removed and
disposed of in accordance with applicable regulations.
• One 10,000-gallon gasoline storage double walled tank and one 10,000-gallon
diesel storage double walled tank are located on an asphalt -paved surface near
the northeast corner of the property. The tanks are provided with secondary
containment in the form of concrete walls. The containment area is
approximately 30 feet by 30 feet by 3 feet, which equates to an approximate
storage capacity of 2,700 W, or approximately 20,200 gallons. Spilled material
collected within the containment area is removed and disposed of in accordance
with applicable regulations.
One fueling station with four pumps is located on an asphalt -paved surface near
the northeast corner of the property. The fueling station is covered and
equipped with an emergency shut off valve. The fueling station is provided with
secondary containment in the form of a trench drain. Spilled material collected
within the containment area is removed and disposed of in accordance with
applicable regulations.
• Oil drums are stored under cover outside the Oil House. The area is not
equipped secondary containment or with a berm.
• Materials are stored in totes and drums in a covered shed located at the
northeastern portion of the facility. The entrance to the shed is equipped with an
asphalt berm to minimize the potential impact of spills on stormwater.
• Materials are stored in totes and drums in a covered shed located at the
southeastern portion of the facility. This area is not equipped with a berm.
• Two totes of oil are stored on the ground without secondary containment in the
shell core unloading area.

Notes:
1. Samples were collected for SWOs 001 & 002 only. Due to the short duration of the storm event on July 19, 2010, representative samples from the
remaining permitted locations (SW004, SW005, SW006, SW007) could not be collected. Further attempts to redo the sampling event while staying
with the confines of a representative event were unsuccessful before the end of the sampling period date of July 31, 2010.
2. Laboratory spilled sample and was unable to take measurement.
3. Sample not collected due to unsafe conditions reaching outfall.
4. Analytical data not yet reported for this timeframe at time of renewal submittal.
5. Analytical data is not available for the August 2010 - January 2011 timeframe as the attempt to sample on November 16, 2010 was unsuccessful due to
it not being a representative storm event. Further attempts to redo the sampling event while staying with the confines of a representative event were
unsuccessful before the end of the sampling period date of January 31, 2011.
6. Sampling/visible inspections are no longer required for SWO07 in line with guidance provided by Michael Parker of DWQ during May 2009 inspection.

Notes:
1. Inspection and sampling data not yet reported for this timeframe at time of renewal submittal.
2. Storm drain inlet covered by woody debris.
3. Inspections completed for SWOs 001 & 002 only. Due to the short duration of the storm event on July 19, 2010, representative sampling from the
remaining permitted locations (SW004, SW005, SW006, SW007) could not be completed. Further attempts to redo the inspection event while staying
with the confines of a representative event were unsuccessful before the end of the sampling period date of July 31, 2010. Since inspections are
completed in conjunction with sampling, inspections were not completed for this timeframe.
4. Inspection data is not available for the August 2010 - January 2011 timeframe as the attempt to sample/inspect on November 16, 2010 was unsuccessful
due to it not being a representative storm event. Further attempts to redo the sampling event while staying with the confines of a representative
event were unsuccessful before the end of the sampling period date of January 31, 2011.
S. Sampling/visible inspections are no longer required for SWO07 in line with guidance provided by Michael Parker of DWQ during May 2009 inspection.

BMP Summary
General Practices
The facility performs inspections of all outside areas and notes any issues that need to
be corrected. Trash is collected in dumpsters.
Materials Storage
Charlotte Pipe encourages proper material storage to prevent the release of materials
and pollutants that may cause stormwater runoff pollution. Proper storage techniques
include:
• Store materials inside of the facility or under cover, when possible.
• Store materials so that there is adequate aisle space to facilitate material transfer
and inspections.
• When appropriate and/or otherwise required, post signs or placards on the
periphery of the storage areas to indicate the hazards associated with the
materials stored within.
• Store containers and drums away from heavy traffic routes, when possible, to
minimize accidental spills.
• Store containers according to the manufacturer's instructions to avoid damaging
the containers from improper weight distribution.
Material Inventory Control
Improved material inventory practices can reduce the waste that results from
overstocking and the disposal of out -dated materials. Careful tracking of all materials
ordered may also result in more.efficient material usage. The following material
inventory BMPs are implemented at the facility:
Material Safety Data Sheets (MSDS) are maintained for all products used at the
facility. A MSDS is requested and maintained on file prior to the use of the
product for which it was written.
• Containers are labeled to show the name and type of substance contained
therein. When appropriate and/or otherwise required, containers will also be
labeled as to the stock numbers, hazards of the materials stored therein,
expiration date, suggestions for proper handling, and first aid information.

Equipment Operations and Maintenance
Charlotte Pipe personnel implement the following equipment operation and
maintenance BMPs as part of the facility's good housekeeping program:
• Stormwater drains are labeled to facilitate employee familiarity with drain
locations and to remind employees that non-stormwater discharges are not
allowed;
• Trash and other solid waste materials are regularly collected and disposed of
appropriately;
• Asphalted outside areas are cleaned each day with a sweeper to remove any
settled particulate debris;
• Equipment is inspected for leaks or conditions, that could lead to discharges of
pollutants or contact of stormwater with raw waste materials;
• Mobile vehicles (company automobiles, forklifts, general purpose vehicles, etc
are maintained to prevent leaking; and
• Equipment, which is not working properly, is promptly repaired.
Structural Control Measures
Charlotte Pipe currently employs three types of structural control measures at the
facility to prevent pollutant contact with stormwater. These structural control measures
include: (1) Preventive Covering, (2) Substance Containment, and (3) Vegetative Cover.
Each of these is discussed in more detail below.
• Preventive covering comprises the physical enclosure of material, equipment, or
process operations, when feasible. Charlotte Pipe has built a 150'L x 120'W x
35' H building along the northeastern portion of our property to enclose the
aggregate waste storage areas thus reducing stormwater exposure.
Substance containment measures are used to physically contain or capture a
release of solid, liquid, or gaseous material. These containment measures
provide a second line of defense by preventing a release of material from the
primary containers to reach down gradient surface water. Containment will
prevent both run-on and run-off.

Secondary containment and spill response and prevention procedures for the
bulk liquid storage containers atthe facility (i.e. the fuel and asphalt above
ground storage tanks located in Area V1I) are described in detail in the Spill
Prevention Control and Countermeasures (SPCC) Plan. Charlotte Pipe also
employs secondary containment for non -petroleum based products by storing
most products used in the manufacturing process inside of the foundry buildings
or under cover and surrounding bulk material spent storage area with berms to
prevent stormwater runoff. Stormwater which accumulates in the containment
areas is at a minimum visually observed for color, foam, outfall staining, visible
sheen, and dry weather flow prior to release of the accumulated stormwater.
Accumulated stormwater is released only if found uncontaminated by the
materials stored within the containment area.
• Vegetative cover on non -impervious areas prevents erosion and improves the
infiltration capacity of the soil. In addition, the vegetation should be maintained
in all areas to prevent erosion. Charlotte Pipe ensures that all areas of the facility
that are not covered in buildings, concrete, asphalt, and gravel pavement, are
provided with vegetative cover.

Significant Changes in Industrial Activities
Charlotte Pipe has made the following significant changes in industrial activities in the
last five (5) years:
Replacement of the fittings emulsion asphalt dip line with an E-coat system. The
fittings emulsion asphalt dip line, which partially ran outside, was removed from
service mid-2013 and is currently in the process of being dismantled. This
modification has the potential to significantly impact stormwater as the new E-
coat system is located inside a building; thus, there is no potential stormwater
impacts associated with its operation.
• The new E-coat applied to castings is expected to be more rust -resistant than the
emulsion asphalt coating previously used; therefore, stormwater impact from
water run-off of the fittings product stored outside should be reduced.
Installation of a 1.50'L x 120M x 35'H aggregate waste storage building along the
northeastern portion of our property. This building enclosed the aggregate
waste storage areas thus eliminating stormwater exposure from waste aggregate
pile run-off.
