showing the facility's location in relation to transportation routes and surface waters, and the
name of the receiving water(s) to which the stormwater outfall(s) discharges. 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 must be shown.
(2) A narrative description of storage practices, loading and unloading activities, outdoor process
areas, dust or particulate generating or control processes, and waste disposal practices.
(3)
A site map (or series of maps) drawn to scale with the distance legend indicating location of
industrial activities (including storage of materials, disposal areas, process areas, and loading
and unloading areas), drainage structures, drainage areas for each outfall and activities occurring
in the drainage area, building locations and impervious surfaces, the percentage of each drainage
area that is impervious. For each outfall, a narrative description of the potential pollutants which
could be expected to be present in the regulated stormwater discharge.
(4) A list of significant spills or leaks of pollutants that have occurred at the facility during the 3
previous years and any corrective actions taken to mitigate spill impacts.
(5)
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 III, Standard Conditions, Section B.11.
b. 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 non-structural measures. The stormwater
management plan, at a minimum, shall incorporate the following:
(1) A study addressing 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 practicable the permittee should consider covering storage areas, material
handling operations, manufacturing or fueling operations to prevent materials exposure to
stormwater. In areas where elimination of exposure is not practicable, the stormwater
management plan shall document the feasibility of diverting the stormwater runoff away from
areas of potential contamination.
(2) 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 materials 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

Permit NC0086169

(3)
that accumulates in the containment area shall be at a minimum visually observed prior to
release of the accumulated stormwater. Accumulated stormwater shall be released if found to be
uncontaminated. 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.
A narrative description 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 contributing significant quantities of pollutants to
stormwater discharges and data collected through monitoring of stormwater discharges.
(4) Inspection schedules of stormwater conveyances and controls and measures to be taken to limit
or prevent erosion associated with the stormwater systems.
c. Spill Prevention and Response Plan: The Spill Prevention and Response Plan shall incorporate a risk
assessment of potential pollutant sources based on a materials inventory of the facility. Facility personnel
(or team) responsible for implementing the plan shall be identified in 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.

THIS FACILITY HAS BEEN MOTHBALLED. AS SUCH, THIS PERMIT RENEWAL IS A
SIMPLE ROLLOVER OF THE PREVIOUSLY ISSUED PERMIT AND ALL SUBSEQUENTLY
ISSUED MODIFICATIONS.
SUMMARY OF FACILITY AND WASTELOAD ALLOCATION
Corning Incorporated manufactures optical fibers at its Midland facility in Cabarrus County. The facility
originally received its National Pollutant Discharge Elimination System (NPDES) permit in 1998. Startup
began late that year. The facility was issued a renewed NPDES permit on March 31, 2004, which
included an expanded flow to 0.142 MGD for the outfall 003.
Wastewater generated includes sanitary wastewater, non -contact cooling wastewater, process wastewater,
stormwater, filter backwash water and boiler blowdown. Currently, sanitary wastewater is treated off -site
at the Muddy Creek Wastewater Treatment Plant. Wastewaters other than sanitary are treated and
discharge through one of three outfalls as summarized below.
Outfall 001
This discharge is comprised of 100% stormwater, collected in a stormwater retention pond. The receiving
stream is an unnamed tributary of Muddy Creek. Currently, no effluent limitations and monitoring page
is contained within the permit for this outfall, though stormwater controls are required. Part I, Section A,
Number 8 of the permit addresses stormwater discharges and applicable monitoring requirements.
Outfall 002
This discharge is comprised of stormwater, non -contact cooling water, and humidification boiler
blowdown. Wastewater is collected in a wet detention pond prior to discharge into an unnamed tributary
of Clear Creek. Effluent limitations and monitoring have been applied and stormwater controls are
required.
Outfall 003
Corning Fact Sheet
NPDES Renewal
Page I

This discharge is comprised of industrial process wastewater, non -contact cooling water, and carbon filter
backwash water. These wastewaters are neutralized and treated using a solids removal unit prior
discharge into the Rocky River.
TOXICITY TESTING:
Current Requirement: Chronic P/F @ 1.0% at 0.107 MGD using Ceriodaphnia
Proposed Requirement: Chronic P/F @u 1.7% at 0.142 MGD using Ceriodaphnia
The above IWCs were calculated using a flow equal to the sum of the permitted flow at outfall 003 and the
non -contact cooling water contribution.
This facility has passed all toxicity tests since startup.
COMPLIANCE SUMMARY:
The facility has been in compliance with its NPDES Permit.
INSTREAM MONITORING:
A benthic macroinvertebrate study was required in the original permit. That permit required the facility to
complete a benthic survey during the summer of 1999. The study was completed in August and
submitted to the Division for review. Dave Lenat of the Environmental Sciences Branch reviewed the
study and provided the writer with comments. His conclusions were in agreement with the study results,
which indicated no biological impact from this discharge. As the discharge will be expanding, the benthic
survey requirement will be included with this renewal, and should be completed upon completion of
expansion, should such expansion take place.
PROPOSED CHANGES:
None

evaluated prior to this plant being built, and this Office is unaware of any of changes in the
status of these alternative at this time. Corning discharges all domestic wastewater into the
Water and Sewer Authority of Cabarrus County's Muddy Creek WWTP, however, there is
insufficient capacity at the Muddy Creek WWTP to accept all of Corning's waste streams.
PART IV - EVALUATION AND RECOMMENDATIONS
Corning, Inc. requests the reissuance of an NPDES Permit for the discharge of both process
water and non -contact cooling water from a facility located southern Cabarrus County. The Corning
facility began limited operation again in in the fall of 2007 after being closed (mothballed) for
nearly 5 years due to poor economic conditions.
The process water discharge (outfall 003) contains the following sources of wastewater:
1. Blowdown from pollution abatement equipment.
2. Water softener from area floor drains.
3. Water softener blowdown.
4. Cooling tower blowdown.
5. Some stormwater.
The two (2) cooling water outfalls (001 & 002) leave the site only after passing through a
wet detention basin. During periods of infrequent rainfall these basins may hold little, if any water.
However, during wet -weather, these basins may hold substantial quantities of water, which will be
made up primarily of stormwater. Most of the site's stormwater has been channeled around the
detention basins, however, there will still be a considerable quantity of that enters the basins either
directly or indirectly.
Pending receipt and approval of the draft permit, it is recommended that the NPDES Permit
be reissued as requested.
