Subject: Final NPDES Stormwater Permit
Permit NCS000255
Citation Castings
Montgomery County
Dear Mr. Saddix:
In response to your renewal application for continued coverage under NPDES stormwater permit
NCS000'U the Division of Water Quality (Division) is forwarding herewith the subject state - NPDES
permit. This permit is issued pursuant to the requirements of North Carolina General Statute 143-215 .1
,and the Memorandum of Agreement between North Carolina and the US Environmental Protection
agency dated May 9,1994 (or as subsequently amended).
This final permit includes some changes from the draft permit sent to you on April 11, 2007.
1. The definition of "total flow" has been removed per our telephone discussion.
2. This spring, the Division re-evaluated benchmark values for analytical sampling.
Three of the changes represent corrections to the number of significant figures, and
two represent re -calculations of benchmark values. The reduction in phenols stems
from a change in chemical reduction strategy based on input from the Division's
Standards and Classifications Unit. The reduction in cadmium stems from recent
scrutiny by the NC Environmental Management Commission. A reduction in the
State standard for cadmium was proposed this spring. These are summarized below
in the format "previous draft"/"current permit":
i. Phenols: 5.3/4.5
ii. Total Cadmium: 0.014/0.001
iii. Total Copper: 0.0073/0.007
iv. Total Lead: 0.0338/0.03
v. Total Nickel: 0.261/0.26
PIease note that analytical monitoring is required in this permit. Failure to complete the monitoring as
required is a violation of the permit and any permit noncompliance constitutes a violation of the Clean
Water Act. Reference Part III, Section A, Item 2 "Duty to Comply", Item 9 "Penalties for Tampering " and
Item 10 "Penalties for Falsification of Reports" of your permit for further information.
Please continue to monitor stormwater discharge outfalls (SDOs) SDO-1 and SDO-2 during this permit
cycle. Though you have noted on your permit renewal application that SDO-2 drains only a small
portion of your site, you did not conduct all of the required monitoring for SDO-2 during the previous
permitting cycle. Partial analysis for this outfall was conducted on September 18, 2003 and June 8, 2004.
The following parameters were found to be in excess of the current benchmark levels for at least one
analysis: COD, Cu, Zn, and TSS. If your sampling during the upcoming permit cycle shows that SDO-2
is consistently below benchmark values, it may be considered for representative outfall status for the next
permitting cycle.

2. 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. 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 stormwater. 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, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
b. Secondary Containment Schedule. A schedule to 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 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. 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 years.
C. BMP Summary. A narrative description shall be provided of Best Management
Practices (BMPs) to be considered such as, but not limited to, oil and grease
separation, debris control, vegetative filter strips, infiltration and stormwater
detention or retention, where necessary. The need for structural BMPs shall be
based on the assessment of potential of sources to contribute significant quantities
of pollutants to stormwater discharges and data collected through monitoring of
stormwater discharges.
1 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 team) responsible for implementing the
SPRP shall be identified. 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, a SPCC plan may be a component of the SPRP, but may
Part II Page 2 of 7

Permit No. NCS000255
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 program shall be developed. The program shall document schedules of
inspections and maintenance activities of stormwater control systems, plant equipment
and systems. Inspection of material handling areas and regular cleaning schedules of
these areas shall be incorporated into the program.

minimum on an annual basis on proper spill response and cleanup procedures and
preventative maintenance activities'for all personnel involved in 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.
6. 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.
7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants to surface waters. The Stormwater Pollution
Prevention Plan shall be reviewed and updated on an annual basis.
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 a9cordance with
Part 111, Standard Conditions, Section B, Paragraph 3) to the Director that the changes
have been made.
8. Facility Inspection Program. Facilities are required to inspect all stormwater systems on
at least a semiannual schedule, once in the fall (September -November) and once in the
spring (April - June). The inspection and any subsequent maintenance activities
performed shall be documented, recording date and time of inspection, individual(s)
making the inspection and a narrative description of the facility's stormwater control
systems, plant equipment and systems. Records of these inspections shall be incorporated
into the Stormwater Pollution Prevention Plan.
Stormwater discharge characteristic monitoring as required in Part I1 of this permit shall
be performed in addition to facility inspections.

SECTION C: QUALITATIVE MONITORING REQUIREMENTS
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status and shall be performed as specified below in Table 4. Qualitative
monitoring is for the purpose of evaluating the effectiveness of the Stormwater Pollution
Prevention Plan (SPPP) and assessing new sources of stormwater pollution.' No analytical tests
are required. Qualitative monitoring of stormwater outfalls is performed when stormwater
discharge occurs but does not need to be performed during a representative storm event.
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 Stormwater Pollution Prevention
Plan.
All qualitative monitoring will be performed twice per year, once in the spring (April - June) and
once in the fall (September - November).

History:
1 January 1995: First issued to Citation Corporation for Foundry Service Company, to Lick Creek
(class C) in the Yadkin -Pee Dee River Basin. This required annual monitoring for TSS, COD, Cu,
Zn, Cd, Pb, Ni, TKN, phenols, and used cutoff concentrations. Vehicle maintenance monitoring
was required for pH, oil and grease, Pb, TSS, and detergents containing methylene blue active
substances (MBAS).
• 1 March 2000: Re -issued requiring seven samples per cycle without cutoff concentrations.
Vehicle maintenance monitoring was required, but no MBAS or Pb.
• 3 December 2002: Corrected the River Basin from Yadkin -Pee Dee to Cape Fear. The receiving
stream classification was also corrected at this time (revised from C to WS-111). There is a Lick
Creek in the Yadkin River Basin that has a C classification, which may have been the source of the
original error.

Central Office Review Summary:
General Observations: This facility has not completed all of the requirements of the previous permit.
A site visit may be pertinent for this facility if one has not already been conducted recently.
Specifically, the analytical monitoring data shows excursions beyond the current benchmark values
and is incomplete, the permittee needs guidance on determining the locations of outfalls and needs
determination of representative outfall status, and the`qualitative data is also of concern. Additionally,
the application references solid waste disposal dumpsters, which may contain oily'metal scraps that
may contaminate the stonnwater. The applicant also notes that there is HAZMAT onsite. The site
plan shows that there is an illicit connection "to be removed" at CB432, that CB# 12 is "to be
plugged", and that "quench water was to be routed to SS" at CB#41. Were these actions taken? If not,
do they need to be? CB#41 also appears to have a source inside a building that discharges to a
stormwater ditch, but this is not specified as an outfall. There are used sand piles onsite. These piles
may contribute to TSS, and they may also have other contaminants. Do they?
2. I pairment: Lick Creek, is classified as WS-III. Lick Creek is not classified as impaired on the 303(d)
list. However, it drains to Cotton Creek, which is impaired for biological integrity. The Basinwide
Plan cites the Star WWTP as the source of the standard violations, not this facility.
3. Industrial Changes Since the Previous Permit; There have been no significant industrial changes to the
facility since the previous permit.

Analytical Monitoring Data:
As shown in Table 1, the permittee failed to submit all of the required analytical data. COD, copper,
zinc, and TSS are consistently high. Phenols, cadmium, lead, nickel, and total kjeldahl nitrogen have
been below the current benchmark for the samples provided. The permittee did not record rainfall
depth, rainfall duration, or flow volume data for the previous cycle. The permittee also failed to
sample both outfalls throughout'the previous permitting cycle.

Permit Changes: Analytical Monitoring:
1. pH has been added per DWQ revised strategy.
2. Oil and grease has been added because this facility likely uses oils as coolants and/or lubricants in the
machining process.
3. Due to a potential lag time between the expiration of this permit and its renewal, the reviewer has
specified in the permit that the permittee is responsible for all monitoring until the renewal permit is
issued. See Footnote 1 of Tables 1, 4, and 5. This approach is recommended because there has been a
significant lag time since the expiration of the previous cycle. This will provide testing if there is a lag
in future timeframes.
4. Benchmarks have been added to this draft permit.
5. All analytical monitoring has been set to semi-annually.
6. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall and
event duration parameters are in this permit, however.)
7. The permittee is required to collect all of the analytical monitoring samples during representative storm
events as defined in this permit. This is not a change from their previous permit. Qualitative
monitoring does not have to be performed during a representative storm event.
8. The analytical monitoring required by the EPA Sector -Specific permit; copper, zinc, and total
suspended solids, were already included in the previous permit and are also included for the upcoming
permit cycle.
Permit Changes: Other Proposed Changes:
l . Part II Section A has been revised. It now specifies all of the items to include on the site map.
2. Vehicle maintenance has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
3. The permittee is encouraged to use form SWU-242-020705 for qualitative monitoring reporting and
SWU-246-051100 for analytical monitoring required. The permittee is required to report all of the
information on these forms (or subsequent forms as amended).
4. twill inform the permittee in -the cover letter of the permit that the minimum detection limits for all
analytical reporting requirements should be below the benchmarks specified in the permit.
5. The permittee states in their application that they have determined that SDO 002 can be represented by
SCO 001. 1 will point out to the permittee that they do not have the authority to make that
determination. The applicant has applied for representative outfall status for the upcoming cycle. If
there is a site visit, DWQ should determine whether or not to grant this status. The permittee reports
that SDO 002 drains less than 2% of the facility. However, this area is of considerable size (10,282
ft�) and is also 90% impervious. We should consider "outfalls" as discharge points from the facility.
These are areas where flow leaves the property via pipes, trenches, gullies, swales, ditches, etc. Each
of these discharge points must be sampled unless DWQ grants representative outfall status. Also note
on the facility map that there may be more outfalls than just 001 and 002. For instance, does CB#42
leave the site? Others?
6. I will point out to the permittee that they are to report their data in the units specified in the permit

Recommendations: Based on the documents reviewed, the application information first submitted on July 30,
2004 is sufficient to issue an Individual Stormwater Permit.

I Measurement Frequency: All monitoring will be performed two times per year for each year until either another
permit is issued for this facility or until this permit is revoked or rescinded. If at the end of this permitting cycle,
the permittee has submitted the appropriate paperwork for a renewal application before the submittal deadline, the
permittee will be considered for a renewal application. The applicant must continue semi-annual monitoring until
Part II Page 4 of 7

Permit No. NCS000255
the renewed permit is issued. See Table 2 for schedule of monitoring periods through the end of this permitting
cycle.
2 If the stormwater runoff is controlled by a stormwater detention pond, a grab sample of the discharge from the
pond shall be collected within the first 30 minutes of discharge. if the detention pond discharges only in response
to a storm event exceeding -a ten year design storm, then no analytical monitoring is required and only qualitative
monitoring shall be performed.
3 Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless representative
outfall status has been granted.
4 The permiuce may choose to use SWU-246-051100 (or subsequent as amended) for analytical monitoring,
though this format is not required.

SECTION C: QUALITATIVE MONITORING REQUIREMENTS
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status and shall be performed as specified below in Table 4. Qualitative
monitoring is for the purpose of evaluating the effectiveness of the Stormwater Pollution
Prevention Plan (SPPP) and assessing new sources of stormwater pollution. No analytical tests
are required. Qualitative monitoring of stormwater outfalls is performed when stormwater
discharge occurs but does not need to be performed during a representative storm event.
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 tal pn in response to the
discovery. This documentation will be maintained with the Stormwater Pollution Prevention
Plan.
All qualitative monitoring will be performed twice per,year, once -in the spring (April -.Tune) and
once in the fall (September - November).

Permit No. NCS000255
analytical monitoring as specified below in Table 5. This monitoring shall be performed at all
outfalls which discharge stormwater runoff from vehicle maintenance areas.
All analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of ten analytical samplings being conducted over the term of
the permit at each stormwater discharge outfall (SDO) which discharges stormwater runoff from
vehicle maintenance areas. The permittee shall complete the minimum ten analytical samplings
in accordance with the schedule specified in Table 2 (Section B).
Monitoring results shall be compared to the benchmark values in Table 6. The benchmark
values in Table 6 are not permit limits but should be used as guidelines for the permittee's
Stormwater Pollution Prevention Plan (SPPP). The permittee shall evaluate the sources of any
benchmark exceedances and evaluate the effectiveness of any4siteBMPs. The permittee shall
review and/or update the SPPP and document any efforts tot ad'fess stormwater contamination.

Severe Property Damage
Means substantial physical damage to property, damage to the control facilities which causes them to
become inoperable, or substantial and permanent loss of natural resources which can reasonably be
expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused
by delays in production.
Significant Materials
Includes, but is not limited to: raw materials; fuels; materials such as solvents, detergents, and plastic
pellets; finished materials such as metallic products; raw materials used in food processing or production;
hazardous substances designated under section 101(14) of CERCLA; any chemical the facility is required to
report pursuant to section 3 l3 of Title III of SARA; fertilizers; pesticides; and waste products such as ashes,
slag and sludge that have the potential to be released with stony water lischarges.

The discharge from any point source which is used for collecting and conveying stormwater and which is
directly related to manufacturing, processing or raw material storage areas at an industrial site. Facilities
considered to be engaged `in' ,'Iindustrial activities' include those activities defined in 40 CFR 122.26(b)(14).
The term does not include discli rges from facilities or activities excluded from the NPDES program.
Stormwater Pollution Prevention Plan
A comprehensive site -specific plan which details measures and practices to reduce stormwater pollution and
is based on an evaluation of the pollution potential of the site.
Ten Year Design Storm
The maximum 24 hour precipitation event expected to be equaled or exceeded on the average once in ten
years. Design storm information can be found in the State of North Carolina Erosion and Sediment Control
Planning and Design Manual.
Total Flow
The flow corresponding to the time period over which the entire storm event occurs. Total flow shall be
either; (a) measured continuously, (b) calculated based on the amount of area draining to the outfall, the
amount of built -upon (impervious) area, and the total amount of rainfall, or (c) estimated by the
measurement of flow at 20 minute intervals during the rainfall event.

31. Total Maximum Daily -Load (TMDL}
A TMDL is a calculation of the maximum amount of a pollutant that a waterbody can receive and still meet
water quality standards, and an allocation of that amount to the pollutant's sources. A TMDL is a detailed
water quality assessment that provides the scientific foundation for an implementation plan. The
implementation plan outlines the steps necessary to reduce pollutant loads in a certain body of water to
restore and maintain water quality standards in all seasons. The Clean Water Act, section 303, establishes
the water quality standards and TMDL programs.
