1 Wastewater Treatment Plant Upgrade-Phase I No 6001727 A new 1-million gallon Equalization Tank(EQ),used to 100% 2019-2021 14,582,301 No
6001728 attenuate flow and organic loading,will be installed to
6001731 supplement inventory control management to work with the
6001782 existing EQ tank. The new EQ tank will have an internal mixing
6001726 system that uses compressed air(blower)via a compressor to
6001820 produce coarse air bubbles that keeps the solids mixed. In
order to manage inventory of wastewater from the new and
existing EQ tankage,3 new centrifugal pumps will be installed
between the existing Headworks Building and exiting EQ tank
to allow for multiple transfer options between EQ tanks. After
the wastewater leaves the new EQ tanks,it will be filtered by
new automatic filters to a particle size of 1mm. This small
particle size removal will allow for good mixing without buildups
on the internal media in the downstream MBBR units. To
support the Electrical,Instrumentation,and Automation
requirements of both Phases,a new MCC Building will be built
on a re-purposed existing foundation.

If any parts,measurement frequencies,or sampling requirements contained in this permit are unacceptable
to you,you have the right to an adjudicatory hearing upon written request within thirty(30)days following
receipt of this letter. Unless such demand is made,this decision shall be final and binding.

Re: Amended Industrial User Permit
Mr.Roura:
Enclosed please the renewed Industrial User Permit#0001-02.Please read all sections carefully as some
language was amended to reflect name changes and EPA requirements.
Please note the sampling responsibility for the facility remains assigned to the Control Authority(Town of
Clayton)or its designee.The only exception is the daily flow rate. Grifols has a right to split samples
during any event. Should Grifols decide to collect samples on the effluent the results will need to be
submitted to the Control Authority.
Grifols submitted an up to date spill and slug control plan and should plan to continue implementation.
The current treatment option to discharge the higher strength wastewater will expire in 2020 unless the
agreement is renewed.It is expected that this renewal up to 900,000 gallons per day will happen as
previously discussed with Johnston County.However,ultimately compliance with this permit is the
responsibility of Grifols. Should the agreement not be renewed the limits would be expected to return to
domestic strength levels.
If any parts,measurement frequencies,or sampling requirements contained in this permit are unacceptable
to you,you have the right to an adjudicatory hearing upon written request within thirty(30)days following
receipt of this letter. Unless such demand is made,this decision shall be final and binding.
Please contact me directly at 919-553-1536 if you have any questions.

Re: Industrial User Permit Renewal
Mr.Roura:
Enclosed please the renewed Industrial User Permit#0001-02.Please replace the amended sheets to the
current permit.The amended sheets were necessary due to comments by the North Carolina Department of
Environmental Quality Pretreatment Unit.The detection levels for several metals were changed and two
minor typos corrected.The Town was required to base the EPA categorical limits on the combined waste
stream formula.
If any parts,measurement frequencies,or sampling requirements contained in this permit are unacceptable
to you,you have the right to an adjudicatory hearing upon written request within thirty(30)days following
receipt of this letter. Unless such demand is made,this decision shall be final and binding.

Combined Wastestream Formula= (Total Regulated Wastestream/ Total
Wastestream)=517,000/588,000= .88
The following p assigned were assi ed numerical limits in this IUP based
on the categorical regulations for monthly limits. These limits do not result
in over allocations.
Acetone: 8.2 mg/1 * .88=7.216 mg/1
n-Amyl Acetate: 8.2 mgf 1 * .88 =7.216 mg/1
Ethyl Acetate: 8.2 mg/1 * .88 = 7.216
Isopropyl Acetate: 8.2 mg/1 * .88=7.216
Methylene Chloride .7 mg/1 * .88= .616 mg/I
RATIONALE#3a:
Over Allocation Prevention,with IU pollutant reduction:
The following pollutants were assigned numerical limits in this IUP based
on allocating the Maximum Allowable Industrial Loading (MAIL)
determined with the Headworks Analysis (HWA) among all Industrial
Users. The total loading of each pollutant from all permitted discharges
does not exceed the MAIL. These limits do not result on over allocations.
RATIONALE#3b:
Interim Limits for IU pollutant reduction:

IUP Synopsis
RATIONALE#4:
4.) Other Rationale for Limitations:
The following rationale was used for developing IUP Limits.
Parameter Q Rationale
BOD Study performed by Hazen &
COD Sawyer.
TSS
T-Nitrogen
T-Phosphorus -
RATIONALE#5a:
Non-Categorical Parameters where No Limit needed or assigned in an IUP:
The following pollutants were not assigned numerical limits in this IUP
because the loadings for these pollutants from this IU were less than 5% of
the MAHL, or extra reserve capacity was available. The loading of these
pollutants from this IU is considered insignificant at this time. One half of
detection limit used for less than values.

Re: Amended Industrial User Permit
Mr.Roura:
Enclosed please the renewed Industrial User Permit#0001-02.Please read all sections carefully as some
language was amended to reflect name changes and EPA requirements.
Please note the sampling responsibility for the facility remains assigned to the Control Authority(Town of
Clayton)or its designee.The only exception is the daily flow rate. Grifols has a right to split samples
during any event. Should Grifols decide to collect samples on the effluent the results will need to be
submitted to the Control Authority.
Grifols submitted an up to date spill and slug control plan and should plan to continue implementation.
The current treatment option to discharge the higher strengthwa wastewater will expire in 2020 unless the
agreement is renewed.It is expected that this renewal to 900 000gallonsper g P up day will happen as
previously discussed with Johnston County.However,ultimately compliance with this permit is the
responsibility of Grifols. Should the agreement not be renewed the limits would be expected to return to
domestic strength levels.
If any parts,measurement frequencies,or sampling requirements contained in this permit are unacceptable
to you,you have the right to an adjudicatory hearing upon written request within thirty(30)days following
receipt of this letter. Unless such demand is made,this decision shall be final and
Pna n binding.
Please contact me directly at 919-553-1536 if you have any questions.

Re: Industrial User Permit Renewal
Mr.Roura:
Enclosed please the renewed Industrial User Permit#0001-02.Please replace the amended sheets to the
current permit.The amended sheets were necessary due to comments by the North Carolina Department of
Environmental Quality Pretreatment Unit.The detection levels for several metals were changed and two
minor typos corrected.The Town was required to base the EPA categorical limits on the combined waste
stream formula.
If any parts,measurement frequencies,or sampling requirements contained in this permit are unacceptable
to you,you have the right to an adjudicatory hearing upon written request within thirty(30)days following
receipt of this letter. Unless such demand is made,this decision shall be final and binding.

D. RATIONALE FOR LIMITATIONS:
As listed on the IUP Limits Page(s),PART I, Section F of the IUP.
RATIONALE#1:
Review of IU Monitoring Data,with no Over Allocation situation:
The following pollutants were assigned numerical limits in this IUP based
on a review of monitoring data for the permittee to determine what ranges of
concentrations are currently being discharged. To account for sample
variability a factor was applied to the monitoring data to determine the
permit limit. Permit limits assigned by the Local IUP Control Authority can
not result in an Over Allocation situation for any pollutants.

TSS
Total Nitrogen
Total Phosphorus

RATIONALE#2a:
Categorical Industrial Limits,with no Over Allocation situation:
Check here if Combined Wastestream Formula (CWF) or other categorical
limits calculations were used. If used,Please attach calculations: (see CWF
Spreadsheet,Appendix 6-F)
Were used(attach calculations) I x I
Were not used is
Total Regulated Wastestream= 517,000 gls.= Process water + wash down
water.
Total Diluted Wastestream= 71,000 gls.= Domestic + Cooling water +
Boiler/Cooling tower blowdown.
Total Wastestream= 588,000 gls. avg.daily.
Combined Wastestream Formula= (Total Regulated Wastestream/ Total
Wastestream)=517,000/588,000=.88
The following pollutants were assigned numerical limits in this IUP based
on the categorical regulations for monthly limits. These limits do not result
in over allocations.
Acetone: 8.2 mg/1 * .88=7.216 mg/1 ��
n-Amyl Acetate: 8.2 mg/1 * .88=7.216 mg/1
Ethyl Acetate: 8.2 mg/1 * .88=7.216
Isopropyl Acetate: 8.2 mg/1 * .88=7.216
Methylene Chloride .7 mg/1 * .88= .616 mg/1
RATIONALE#3a:
Over Allocation Prevention,with IU pollutant reduction:
The following pollutants were assigned numerical limits in this IUP based
on allocating the Maximum Allowable Industrial Loading (MAIL)
determined with the Headworks Analysis (HWA) among all Industrial
Users. The total loading of each pollutant from all permitted discharges
does not exceed the MAIL. These limits do not result on over allocations.
RATIONALE#3b:
Interim Limits for IU pollutant reduction:

RATIONALE#4:
4.) Other Rationale for Limitations:
The following rationale was used for developing IUP Limits.
Parameter Rationale
BOD Study performed by Hazen &
COD Sawyer.
TSS
T-Nitrogen
T-Phosphorus
RATIONALE#5a:
Non-Categorical Parameters where No Limit needed or assigned in an IUP:
The following pollutants were not assigned numerical limits in this IUP
because the loadings for these pollutants from this IU were less than 5% of
the MAHL, or extra reserve capacity was available. The loading of these
pollutants from this IU is considered insignificant at this time. One half of
detection limit used for less than values.

determined that all items listed on your application are being'used exclusively for Wastewater
Treatment and are therefore eligible to receive tax certification. No items listed were determined
to be ineligible for Tax Certification.
Please note that as part of this Tax Certification process, the inspector did not make any
efforts to confirm either the cost of the items certified, the year of acquisition, if items have
received other Tax Certifications from Air Quality, Solid Waste or other agencies, or if items

from John Brinkley concerning addition of third blower with necessary piping
modifications at the MBBR tanks. We have reviewed the responses provided in the July
20, 2006 letter and found to be satisfactory. Authorization is hereby granted for
construction of the proposed Talecris's wastewater treatment facility upgrade and
expansion to handle increase in BOD and COD Loadings with the stipulation that the
construction of the proposed facilities sbill not proceed. until the Town. receives a
complete revised set of contract documents signed and sealed by a Professional Engineer
in the State of North Carolins .The construction and installation will.include:
1. Two stage MBBR system, designed to handle 0.5 mgd. average daily flow with
average BODs and COD losdings of 13,340 lbs/day and 20,000 lbs/day,
respectively
2. Ammonium hydroxide feed system for nitrogen feed to MBBR sysleau. The
system will include one 10,000 gallon bulk storage tank, end two chemical feed
pumps(0.02-20 gal/br capacity,oath).
3. Use of the existing liquid Atmr storage tank and installation of two new alum
dosing pumps(0.02-4.5 gal/hr capacity,each).

•
4. Defoamer chemical feed system consisting of one bulls defoamer chemical tank
and two defoamer metering pumps(0.002-1,0 galfhr capacity,each).
5. One 500 gpm capacity Dissolved Air Flotation spat= complete with one DAF

Re:Temporary Limits
Mr.Souza:
As you are aware, Hurricane Matthew resulted in the flooding of the Johnston County Water
Reclamation Facility.As an emergency measure the Town was requested to divert the complete flow
from East Clayton Industrial Area pump station to Clayton.We expect the Johnston County Facility will
be back in service within thirty days.
In order to protect the Clayton plant from upset,the following temporary limits will be in place.
Daily flow: 680,000 gpd on a monthly average,900,000 gpd maximum.
BOD: 300 mg/I on a monthly average.
TSS: 300 mg/I on a monthly average.
Ammonia: 20 mg/I on a monthly average.
Total Nitrogen:25 mg/I on a monthly average.
Total Phosphorus: 10 mg/I on a monthly average.
You may contact me directly at 919-553-1536 if you have questions.

Re: Amended Industrial User Permit
Mr. Roura:
Enclosed please find an amended Industrial User Permit#0001-02. Please attach the new
permit to your current permit.
This amended permit no longer contains maximum daily limits for COD, BOD and TSS.
The maximum daily flowrate was increased to 1.1 mgd with a weekly average of.9 mgd.
The flow limits are necessary to prevent overflow situations at the pump station.
Please note the sampling responsibility for the facility has been reassigned to the Control
Authority(Town of Clayton) or its designee. The only exception is the daily flow rate.
Grifols has a right to split samples during any event. Should Grifols decide to collect
samples on the effluent the results will need to be submitted to the Control Authority.
Grifols will need to submit an updated Spill and Slug control plan by December 31, 2015.
This plan will need to include the new facility and its associated waste streams and a plan
to manage the MBBR effluent during shut down periods.
Grifols will need to keep the existing treatment units post MBBR viable for a minimum
of one year as per the Development Agreement between Grifols and the Town of
Clayton.
If any parts,measurement frequencies, or sampling requirements contained in this permit
are unacceptable to you,you have the right to an adjudicatory hearing upon written
request within thirty(30) days following receipt of this letter. Unless such demand is
made,this decision shall be final and binding.
Please contact me directly at 919-553-1536 if you have any questions.

6001728 attenuate flow and organic loading,will be installed to
6001731 supplement inventory control management to work with the
6001782 existing EQ tank. The new EQ tank will have an internal mixing
6001726 system that uses compressed air(blower)via a compressor to
6001820 produce coarse air bubbles that keeps the solids mixed. In
order to manage inventory of wastewater from the new and
existing EQ tankage,3 new centrifugal pumps will be installed
between the existing Headworks Building and exiting EQ tank
to allow for multiple transfer options between EQ tanks. After
the wastewater leaves the new EQ tanks,it will be filtered by
new automatic filters to a particle size of 1mm. This small
particle size removal will allow for good mixing without buildups
on the internal media in the downstream MBBR units. To
support the Electrical,Instrumentation,and Automation
requirements of both Phases,a new MCC Building will be built
on a re-purposed existing foundation.

from John Brinkley concerning addition of third blower with necessary piping
modifications at the MBBR tanks. We have reviewed the responses provided in the July
20, 2006 letter and found to be satisfactory. Authorization is hereby granted for
construction of the proposed Talecris's wa tawater treatment facility upgrade and
expansion to handle increase in BOD and COD Loadings with the stipulation that the
construction of the proposed facilities shall not proceed until the Town. receives a
complete revised set of contract documents signed and sealed by a Professional F nginrrer
in the State of North Carolina..The construction and installation will include:
1. Two stage MBBR system, designed to handle 0.5 mgd average daily flow with
average BODs and COD loadings of 13,340 lbs/day and 20,000 lbslday,
respectively
2. Ammonium hydroxide feed system for nitrogen feed to MBBR system. The
system will include one 10,000 gallon bulk storage tank, and two chemical feed
pumps(0.02-20 gal/hr capacity,each).

General Statue's 143-215.6Ato 143-215.6C,and Federal Regulations.
Following the commissioning of the proposed plant improvements, effluent from the
DAF will be conveyed to the existing aeration basin followed by the two existing
clarifiers before being discharged to the Town's wastewater collection and treatment
system. A lockable valve ;hall be installed on the DAF effluent discharge pipe to the
Town's wastewater collection and treatment system.This valve will have a Iook provided
by the Town.The intent of such arrangement is to operate the new treatment facilities in
series with the existing wastewater treatment system to gather necessary DAF effluent
quality data to support the direct discharge of DAF effluent to the Town's wastewater
collection system. Fri order to meet the reliability criteria Talecris shall provide another

.
clarifiers unit prior to the removal of the existing aeration basin and. facilities for the
Talecris's expansion needs.
In the event that the ffmitities fail to perform satisfactorily, including the creation of
pni canoe conditions,the Pe mittee si,A1i take immediate corrective action and notify the
Town. Construction of additional or replacement pretreatment facilities will require

Re:Temporary Limits
Mr.Souza:
As you are aware, Hurricane Matthew resulted in the flooding of the Johnston County Water
Reclamation Facility.As an emergency measure the Town was requested to divert the complete flow
from East Clayton Industrial Area pump station to Clayton. We expect the Johnston County Facility will
be back in service within thirty days.
In order to protect the Clayton plant from upset,the following temporary limits will be in place.
Daily flow:680,000 gpd on a monthly average, 900,000 gpd maximum.
BOD: 300 mg/I on a monthly average.
TSS: 300 mg/I on a monthly average.
Ammonia: 20 mg/I on a monthly average.
Total Nitrogen: 25 mg/I on a monthly average.
Total Phosphorus: 10 mg/I on a monthly average.
You may contact me directly at 919-553-1536 if you have questions.

Re: Amended Industrial User Permit
Mr. Roura:
Enclosed please find an amended Industrial User Permit#0001-02. Please attach the new
permit to your current permit.
This amended permit no longer contains maximum daily limits for COD, BOD and TSS.
The maximum daily flowrate was increased to 1.1 mgd with a weekly average of.9 mgd.
The flow limits are necessary to prevent overflow situations at the pump station.
Please note the sampling responsibility for the facility has been reassigned to the Control
Authority(Town of Clayton) or its designee. The only exception is the daily flow rate.
Grifols has a right to split samples during any event. Should Grifols decide to collect
samples on the effluent the results will need to be submitted to the Control Authority.
Grifols will need to submit an updated Spill and Slug control plan by December 31, 2015.
This plan will need to include the new facility and its associated waste streams and a plan
to manage the MBBR effluent during shut down periods.
Grifols will need to keep the existing treatment units post MBBR viable for a minimum
of one year as per the Development Agreement between Grifols and the Town of
Clayton.
If any parts,measurement frequencies, or sampling requirements contained in this permit
are unacceptable to you,you have the right to an adjudicatory hearing upon written
request within thirty (30) days following receipt of this letter. Unless such demand is
made,this decision shall be final and binding.
Please contact me directly at 919-553-1536 if you have any questions.

Review of IU Monitoring Data,with no Over Allocation situation:
The following pollutants were assigned numerical limits in this IUP based
on a review of monitoring data for the permittee to determine what ranges of
concentrations are currently being discharged. To account for sample
variability a factor was applied to the monitoring data to determine the
permit limit. Permit limits assigned by the Local IUP Control Authority can
not result in an Over Allocation situation for any pollutants.

Clayton,NC,Johnston County
Dear Mr. Auge:
•
The Grifols Therapeutics Wastewater Treatment Plant was inspected for Tax
Certification purposes on 2/22/2013. Updates to your Tax Certifications are considered effective
from the date equipment was installed and operational.
Grifols, Talecris, Bayer WWTP equipment and operations at the same site have
previously been inspected and certified for Tax Certification and Exemption purposes for
Wastewater Treatment under authority of DWQ and the Environmental Management
Commission (EMC). The WWTP is located at 8368 US Highway 70 West in Clayton, NC
27520 in Johnston County. The facility holds Pretreatment Permit No. 0001-02 issued by the
Town of Clayton. Tax Certification requires continued compliance with all Division of Water
Quality and Environmental Permits. Should compliance not be maintained please notify James
Warren at the Town of Clayton WWTP, The NC-DWR-Regional Office, this office, and the
Johnston County Tax office.
A copy of your Tax Certificate and Inspection Determination Form are attached to this
letter. Copies are also sent to the County Tax Office. During the inspection and review it was
determined that all items listed on your application are being used exclusively for Wastewater
Treatment and are therefore eligible to receive tax certification. No items listed were determined
to be ineligible for Tax Certification.
Please note that as part of this Tax Certification process, the inspector did not make any
efforts to confirm either the cost of the items certified, the year of acquisition, if items have
received other Tax Certifications from Air Quality, Solid Waste or other agencies, or if items
that have previously received Wastewater Treatment Tax Certification are still present and
operational.
