RE: 2016 Storm Water Report — Hurricane Matthew
RECEIVED
DEQ/DWR
OCT 17 2016
WOROS
FAYETTEVILLE REGIONAL OFFICE
CCT 3 2016
r .
On October 7, 2016, Hexion called Trent Allen of NCDEQ to discuss the imminent impacts of Hurricane
Matthew on the Fayetteville facility and the site's contingency plans to manage the excess rainfall in the
weather forecast. The predicted rainfall was in a range that was similar or more severe than the previous
large rainfall that occurred on September 28-29, 2016. Government officials had declared a state of
emergency prior to Hurricane Matthew reaching North Carolina. During the previous rain event, Hexion
had contacted NCDEQ regarding a plan to use temporary discharge points instead of overflowing the
site's waste water treatment plant. The previous flooding caused serious concerns regarding employee
safety, with pools of water reaching electrical equipment and the potential for significant equipment
damage.
The first part of Hexion's Hurricane Matthew contingency plan discussed with NCDEQ was to utilize
approximately 176,000 gallons (empty tanks and a railcar) to collect the rainfall that fell on the process
areas instead of sending it to the site's waste water treatment plant. The site also had as much freeboard
in the waste water treatment plant as possible without running the pumps dry prior to the rain event.
The second part of Hexion's contingency plan discussed was utilizing the temporary discharge points if
necessary to avoid overflowing the on -site waste water treatment system. Hexion advised its view that
the safest option was moving the rain water off -site to the Cape Fear River using temporary discharge
points. The process area with which the rain water would come in contact would have a first flush by
sending the water to the site's waste water treatment plant prior to using the temporary discharge points.
Qualitative monitoring and pH would be measured at the new temporary discharge points at a minimum
of every hour. It was also agreed with Trent Allen that if the temporary discharge points were required
that Hexion would notify him prior to implementing the temporary discharge points.
Hurricane Matthew brought approximately 15 inches of rain to the Fayetteville site. Hexion experienced
excessive flooding on -site, utilized the extra rain water storage, and implemented the temporary discharge
points. Trent Allen was verbally notified prior to using the temporary discharge points on Saturday
10/8/16 during the storm, Unfortunately these actions were not enough to prevent overflowing the waste
water treatment system. The waste water treatment system overflowed effluent and solids that reached
the storm water outfall which drains to the Cape Fear River. Hexion left a voice mail and contacted Steve
Lewis of NCDEQ on October 10, 2016 regarding the overflow of the waste water treatment plant due to
the extensive rainfall.

In accordance- with our permit NCS000088, enclosed are two copies of this storm water report. Should
you have any additional questions, please do not hesitate to contact me at [phone].

RE: 2016 Storm Water Report
RECEIVED
OCT - 3 2016
DEO-FAYETTEVILLE REGIONAL OFFICE
On the morning of September 29, 2016, Hexion called NCDEQ to discuss safety concerns associated with
the large rain event of approximately 7 inches in 16.5 hours. The event caused government officials to
declare a state of emergency in Fayetteville, where the Hexion facility is located. Hexion spoke with
Brad Cole, Belinda Henson, Toby Vinson, and Bradley Bennett of the NCDEQ.
The immense volume of water, which included drainage from upgradient properties, caused Hexion's
three normal storm water outfalls to Cape Fear River to drain slowly. The flooding caused serious
concern regarding employee safety, with pools of water reaching electrical equipment and the potential
for significant equipment damage. Hexion advised NCDEQ of the options of overflowing the waste
water treatment plant or sending rain water offsite. Hexion advised its view that the safest option was
moving the rain water off -site to the Cape Fear River using temporary discharge points. The process area
with which the rain water came in contact had been flushed the full night prior and sent to the site's waste
water treatment plant.
Hexion implemented this plan throughout the day of September 29 to remove the site's excess rain water
to safe levels. Qualitative monitoring and pH were measured at the new temporary discharge points at a
minimum of every hour as discussed during the phone call (refer to attachment). Hexion implemented
this plan on September 29, 2016 to remove the site's excess rain water to safe levels.
In accordance with our permit NCS000088, enclosed are two copies of this storm water report. Should
you have any additional questions, please do not hesitate to contact me at [phone].
Sincerely,
HEXION INC.

In accordance with our permit NCS000088, this is to provide written notification that on four occasions
the benchmark value of 120 mg/L for COD was exceeded.
The site performed the required actions as required for the Tier One and Tier Two categories. Sampling
has been conducted at locations prior to Outfall 001 in an effort to help determine possible sources. Also
a consultant was hired to provide assistance in identifying the cause of the higher levels of COD.
Below is a s mmary of the COD values at Outfall 001 since sampling was required by the permit.

CENTRAL FILES
DWR SECTION
In accordance with our permit NCS000088, enclosed are two copies of the semi-annual storm water monitoring
report.
Momentive noticed that it had not received the sample results after an extended time after the sampling event.
Therefore Momentive contacted the contract lab to inquire about the report. The lab sent the report on 11/25/14.
Also being reported in this document is an event that is not required to be reported under the 24 hour reporting
requirement of the site storm water permit. An insignificant spill occurred on July 10, 2014 during a large rain
event. A small amount of treated water from the facility's waste water treatment plant entered the storm water
drainage system that drained to the storm water outfall. The amount of any constituents that have a reportable
quantity would be significantly less than the reportable quantity, therefore this is not considered to be a
significant spill by the storm water permit which requires 24 hour reporting. The facility took immediate action
upon discovering the overflow to stop, the material from entering the storm water drainage system. Also as a
long term solution the facility installed an alarm to alert personnel that material is reaching a high level in the
containment dike system where the material overflowed.
Should you have any additional questions, please do not hesitate to contact me at [phone].

RE: 2013 1" Half Semi -Annual Storm Water Report
In accordance with our pen -nit NCS000088, enclosed are two copies of the semi-annual storm water monitoring
report.
Also being reported in this document is information that is not required to be reported under the 24 hour
reporting requirement of the site storm water permit. During an internal EHS audit, the auditor identified that
the secondary containment for certain tank farms at the Facility may not fully meet the requirement in Part III,
section A.2.(b) of the storm water permit — specifically the requirement to include sufficient freeboard to allow
for a 25 year, 24 hour storm event. Following the audit, the facility reviewed its secondary containment
calculations and engaged an outside environmental -consultant to assist in the evaluation of its existing secondary
containment capacity. Based upon this review, it has been determined that, while many of the secondary
containment areas at the facility have sufficient capacity as defined in the petinit, there is not sufficient
freeboard in a few secondary containment areas to allow for a 25 year, 24 hour storm event.
Momentive is currently evaluating potential solutions to address this issue. For one area, Momentive plans to
extend the existing roof to prevent storm water from entering the containment area. In the other areas,
Momentive is evaluating means to increase the secondary containment volume. Engineering design work is
currently being performed to develop bid packages, determine a timeline, and prepare for construction.
