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 II. 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
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.
(3) 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.

• Permit NC0086169
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.

section 102 of CERCLA(Ref: 40 CFR 302.4).
9. Stormwater Runoff
The flow of water which results from precipitation and which occurs immediately following
rainfall or as a result of snowmelt.
10. Total Flow
The flow corresponding to the time period over which the sample collection occurs. The total
flow calculated based on the size of the area draining to the outfall, the amount of the built-
upon (impervious) surfaces within the drainage area, and the total amount of rainfall occurring
during the sampling period.
11. Visible Sedimentation

Per our recent telecon, you asked me to send you an email explaining why Corning Inc. is proposing to
install a diffusion structure in the Rocky River for the NPDES discharge from our Concord plant.
Our desire in installing a diffusion structure is to provide an additional safety factor regarding any
potential impact from our discharge to the receiving stream. While we understand that stream standards
and action levels were considered in evaluating our application and issuing our permit, we believe that a
diffusion structure will provide an even greater protection to the receiving stream by reducing the length
of stream required to attain full mixing of the discharge. It is not our intent to request or justify any
modifications to our NPDES permit as a result of the installation/operation of the diffusion structure.
We intend to use the CoreMix model to evaluate diffusion structure alternatives and select the most
appropriate structure for our discharge and this stream.
I appreciate your consideration of this request, and ask if you could send mereply to these questions:
rrwo , r.. towctrMt Qbasrr„lR, jc4s - ti. �i� " '�• .� 1.' .
1. Does your agency have any objections to the installation of this diffusion structure? We realize that • -
this installation will require coordination with other governmental agencies such as the Corp of 4.6
Engineers.

2. Does your agency have any suggestion for alternates to the use of the CoreMix model at this site? s.•- ,..
3. Is there any additional information you need to be able to anwer these qu stions or during the design
and installation of the structure? "'

I'm sorry we've taken so long to get back to you on this. I appreciate your willingness to consider
phasing in the 1% toxicity concentration.
Based on our construction and start-up schedule, we do not plan to exceed the current permitted flow of
27,400 gallons per day until the 2nd Quarter of 2001. Therefore, we request to maintain our current
effluent concentration of 0.31% for toxicity testing until March 2001. At that time, we would have
increased our flow above 27,400 and would begin toxicity testing at the 1% effluent concentration as
presented in the draft permit.
Please let me know if this is feasible and if you need further information.
Thank-you!
