Dear Mr. Reverri:
In response to your renewal application for continued coverage under NPDES stormwater permit
NCS000050 and agreements reached in September 2006, 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 contains the following minor changes from the draft permit sent to you on
September 29, 2006:
• The footnotes under Table 1. and Table 2. in Part II, Section B. have been revised to reflect annual
monitoring.
• The language in Part II, Sections B. and D. has been revised to include "or each representative '
outfall, if representative status has been granted" in the body of the text next to "each stormwater,
discharge outfall." In addition, this letter verifies representative status of outfall 001 at this site.
Please include this documentation with the facility's permit and SPPP records. '
This letter verifies representative outfall status of outfall 001 at this facility (originally granted in 1995).
The information provided during the renewal process continued to support that this outfall represents
the industrial activities occurring at this site. '
For reference, this final permit reflects following changes from the contested permit issued December-
2, 2005:
" Analytical monitoring frequency in Part 11, Section B. has changed to annual. Semi-annual
monitoring is still required if activities trigger Vehicle Maintenance requirements in Section D-
• The benchmark value for copper has been removed, and Part II, Section E "Mandatory Best
Management Practices" has been added per discussions between SCM Metal and DWQ.
• Zinc and ethylene glycol monitoring have been removed based on information provided by

This site discharges upstream of a segment of Northeast Creek'designated as impaired waters,
experiencing problems with fecal coliform, turbidity, and low dissolved oxygen; and also:
upstream of theJordan Reservoir, experiencing problems with nutrients and chlorophyll a
violations (indicative of excessive nutrient loads). A Total Maximum Daily Load (TMDL) for
fecal coliform was approved in September 2003 for Northeast Creek, but the Permittee was not
allocated a load for stormwater discharge and is not required to monitor for fecal coliform at this '
time. .
If a Total Maximum Daily Load (TMDL) is approved for this segment of Northeast Creek, the
Permittee may be required to monitor for the pollutant(s) of concern in the future and submit
results to the Division of Water Quality. The Division will consider the monitoring results in
determining whether additional BMPs are needed to control the pollutant(s) of concern to the
maximum extent practicable

SECTION E: MANDATORY BEST MANAGEMENT PRACTICES (BMPS)
The Permittee shall implement the following BMPs at this facility and shall include these BMPs.
in the facility's SPPP: ,
(a.) The Permittee shall ensure entryways and loading areas near manufacturing areas where dust
track -out occurs are "swept daily, and that cleaning procedures are conspicuously posted within
the affected work areas.
(b.) The Permittee shall ensure routine evaluations by employee task groups of BMPs intended to
reduce copper dust exposure and shall identify practices or areas in need of improvement.
(c.) The Permittee shall implement BMPs to reduce fugitive dust, including but not limited to:
moving fork truck and sweeper maintenance indoors; improving preventative maintenance for
dust collectors; and handling and storing glycerin in reusable containers. For BMPs that have
already been implemented, the Permittee shall ensure those practices are maintained as long as:
1. they effectively reduce fugitive dust, .
(d.) The Permittee shall devise a Monitoring Plan for sampling runoff from segregated areas (for.,,
example, the main traffic "area contiguous to the Copper Plant) to determine where the primary
contributions of copper to stormwater occur at the. site. This Monitoring Plan shall be submitted
to DWQ for review and approval within four months of the effective date of this permit [by
February 28, 20071. The Monitoring Plan should require sampling (grab samples) be conducted ;
during representative storm events: In addition to other parameters the Permittee deems useful,
the Permittee shall analyze copper concentration, pH, and estimate flow volume'for each sampled
event. If averages will be used, the plan should include criteria about how many samples are -
required. If the Permittee will evaluate the proportion of contribution to the total mass of copper,
in runoff from the entire site, measurements should be taken concurrently at stormwater
discharge outfalls.
Revisions to the Monitoring Plan shall not require a revision to the Stormwater Permit. Any
'revision of the Monitoring Plan after the initial review and approval of DWQ shall be
accomplished by mutual agreement between DWQ and the Permittee.
(e,) For areas the Permittee has determined to be primary contributions to copper in runoff from
this facility, either through the above Monitoring Plan or by other means, the Permittee shall
assess BMPs intended to reduce dust release and track -out from industrial activities, improve
dust collection efficiency, reduce other sources of copper contamination, and/or capture and treat
the runoff with engineered controls. The Permittee shall establish a schedule to implement
selected BMPs and shall submit a status report to DWQ outlining progress two"and a half years
following the effective date of this permit [by April 30, 20091.

Permit No. NCS000050 �
SCM Metal Products, Inc.
Durham County . .
Dear Mr. Reverri:
In response to your renewal application for continued coverage under NPDES Stormwater permit :
NCS000050, 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 May9,1994 (or as subsequently amended)..
This final permit contains the following minor changes from the draft permit sent to you on
September 28, 2005: '
• The second paragraph of Part I, Section $has been revised, with standard language regarding .
Water Quality Standards.
The Monitoring Schedule table (Table 2., Section B.) has been revised to include the tenth
sampling period that falls before the expiration date of the permit.
In response to your comments received November 8; 2005, the copper and zinc benchmark values are
derived from the EPA Multi -Sector Permit benchmarks for the primary metals industry.' (See Federal'.
Register%Vol- 65, No. 210/October 30, 2000). The ethylene glycol benchmark is based on one-half of the
Final Acute Value ('A FAV), a value the Division often uses to protect aquatic life from acute effects of., .
toxicants in point source discharges. Because stormwater. events are sporadic in nature, several of our
current stormwater benchmarks are based on values that take into account acute effects on aquatic life.
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:
:. If any parts,' measurement frequencies or sampling requirements contained in.this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty,
(30) days following receipt of this letter. This request must be in the form of a written petition, .
conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of
'Administrative Hearings,. Post Office Drawer 27447, Raleigh, North Carolina 27611-7447. Unless such
demand is made, this decision shall be final and binding.

If a Total Maximum Daily Load (TMDL) is approved for this segment of Northeast Creek, the
Permittee may be required to monitor for the pollutant(s) of concern in the future and submit .
results to the Division of Water Quality. The Division will consider the monitoring results in
determining whether additional BMPs are needed to control the pollutant(s) of concern to the
maximum extent practicable.
If additional BMPs are needed to achieve the required level of control, the Permitiee will be
required to (1) develop a strategy for implementing appropriate BMPs, and (2) submit a
