1 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture electronic
crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA Effluent
Guidelines for the facility subject to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11; for semiconductor manufacture use
the definition as found in 40 CFR 469.12; for electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray tube manufacture use
the definition found in 40 CFR 469.31).
Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring may be
waived. The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General Permit. For those
facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic
organics (TTO), I certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are
exposed to rainfall or stormwater runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the
all the provisions of the solvent management plan included in the Stormwater Pollution Prevention Plan."

Re: Semi-annual Stormwater Monitoring Report for — Year 9 Period 2
Mallinckrodt Raleigh Pharmaceutical Plant [SpecGx LLC]
NPDES Individual Stormwater Permit No. NCS000136
Attention: Central Files
Attached are two (2) signed copies of the Stormwater Discharge Outfall (SDO) Monitoring Report
for Year 9 — Period 2 (June 1, 2020 through November 30, 2020) as required by Part III, Section
E of the above -referenced permit.
Please note that our permit expired on December 31, 2016 and we submitted a permit renewal
application to your office on June 1, 2016 prior to the renewal application deadline. It is our
understanding that the NCDEQ-DEMLR requires Mallinckrodt to continue monitoring our
stormwater outfalls under the same "semi-annual" frequency specified in our current permit until
we receive a new permit. Therefore, the next semi-annual storm water sample will be collected
between December 1, 2020 and May 31, 2021 unless we hear otherwise from your office.
If anyone in your office has any questions concerning this report, please do not hesitate to call me
at 919-878-2895.
Regards,
SpecGx LLC
