RE: Follow-up Report on Wet Well Overflow
MalIinckrodt LLC, Raleigh Pharmaceutical Plant
Dear Mr. Smith:
1= COVIDIEN
On April 4, 2013, I contacted Mack Wiggins of your office to report a release of wastewater
which was contained on site during a power failure at our on -site wastewater treatment plant.
The release occurred at approximately 8:00 PM on April 3, 2013 and wastewater overflowed
from a wastewater wet well (sump) into a nearby pond, known as the Flush Water Pond. During
the call, I reported that 6,500 gallons were released but an estimate of 6,750 gallons is now
believed to be more accurate. This letter serves as a follow-up response to that verbal
notification as requested by Mr. Wiggins.
At about 7:55 PM, power was lost at our wastewater treatment plant and the emergency
generator immediately cut on to power the pumps in the wet well. Unfortunately, the switch on
the generator malfunctioned and did not transfer the power to the pumps and wastewater effluent
was thereby released from this wet well into the 2-acre Flushwater Pond where it was fully
contained. Within 45 minutes of the release, power was restored at the wastewater treatment
plant and the pumps were manually re -set and operational. We are still investigating the cause of
the malfunctioning switch and will either repair or replace the switch.
Our wastewater effluent is a combination of treated production -related wastewaters, untreated
sanitary wastewaters, and untreated utility -related wastewaters (e.g., steam condensate, cooling
tower blowdown, etc.) and we discharge our wastewater effluent in accordance with City of
Raleigh Industrial Discharge Permit #CHEM. This subject wet well is a concrete sump used for
pumping Mallinckrodt's combined wastewater effluent to the City of Raleigh sewer system.
The water in the Flushwater Pond is used to flush the lines used for the application of treated
wastewater residuals onto 29 on -site hayfields pursuant to Residuals Application Permit
#WQ0005537 issued by NCDENR. The Flushwater Pond has no direct discharge outlet but is
designed to discharge through a vertical overflow pipe and into our on -site 23-acre Stormwater
Retention Pond near the Neuse River. The Stormwater Retention Pond is covered by the site's
NPDES Stormwater Discharge Permit #NCS000136 issued by, NCDENR. The Stormwater
Retention Pond does not have an overflow and must be routinely pumped for discharge to the
Neuse River. The Flushwater Pond did not overflow into the Stormwater Retention Pond during
this event.

Dear Mr. Smith:

� 4pgt�n�ti �,'ICB
Attached is a copy of the Stormwater Annual Data Monitoring Report (DMR) — Year -2011, as
required by Part 111, Section E of the above -referenced permit.
Results of these analyses indicate that one parameter, ammonium sulfate (calculated results of 15.09
milligrams per liter [mg/L]), exceeded its benchmark value of 13.75 mg/L at outfall MC002 during
the October 11, 2011 sample event. According to our permit and in response to this exceedence, we
are required to evaluate the effectiveness of any site best management practices (BMPs) associated
with this exceedence plus review and/or update the Stormwater Pollution Prevention Plan and
document any efforts to address stormwater contamination. However, because the benchmark value
was recently increased to 19 mg/L in site's new permit (effective December 1, 2011), we do not
believe further evaluation of this particular monitoring result is required at this time nor is there a
need to update the Stormwater Pollution Prevention Plan (SWPPP). Please note that Mallinckrodt
will be updating our SWPPP during the next few months to address new and modified conditions in
our new permit.
If anyone in your offices has any questions concerning this report, please do not hesitate to call me at

has a concrete pad that has epoxy coating and is sealed
with "Waterstop". The base is sloped to collection
trenches in the rear of the storage area. There is also a
speed bump on the western side that is open for roadway
access and prevents rainwater from running onto the
pad.
Hazardous Waste Storage Pad
Procedural BMPs: Hazardous waste materials are stored in appropriate new
(5-20)
drums depending on the nature of the hazardous waste or
hazardous material to ensure no incompatible materials
stored in the same bay. The drums that are sealed are
then placed four to a pallet (maximum) with all drums
touching to prevent tipping. Provisions are made to
stack drums at safe heights and adequate aisle space is
maintained between the pallets. Stonnwater
accumulation in the drainage trenches at the base of the
pad is typically evaporates. Should excess stormwater
accumulate in this trench, a vac truck collects the
stormwater and transports to the W WTP for disposal.
