There are two companies at this location: Nouryon and HenkeL Nuoryon is the permittee for the pretreatment system for both facilities. Nouryon is
responsible for pretreatment compliance.
PART II - PLANT TOUR - Visit all areas where wastewater is generated or where there are drains to the POTW.
Plant Tour Section A - PRODUCTION AND STORAGE AREAS
1. Are there floors drains in the production arak? YES
Where do they go?
Floor drains in the production areas for Nouryon are as follows: All drains in the production area go to a sump, with 5 sumps total. These
consist of Area 1, Area 2 (Tank 97), Areas 3 & 4 which combine, and a sump behind shipping which is for stormwater. All sumps are
automatic except Area 2 sump, which is manual. Area 2 sump is an above ground tank also called "Tank 97 ".
Floor drains in the process area for Henkel are as follows: Floor drains go to a Henkel holding pit, then gets pumped to another Henkel
holding pit located between HI 24 and H117, then pumped to Nouryon 's lift pump which discharges to Nouryon 's wastewater treatment system.
Henkel 's discharge sumps (Saturn and H101) combine at Area 4 sump and 65K tank
2. Are production areas diked, contained, or otherwise constructed in such a way as to prevat harm to the WWTP, especially from spills or
slugs? YES
Where do they go?
Nouryon: Outside production areas are diked and inside production areas drain to sumps, which can be shut off if a spill were to occur.
Henkel: Production areas are either diked or the drains in production areas drain to sumps, which can be shut off if a spill were to occur.
3. Are there floor drains in the storage area? YES
Where do they go?
All drains in the storage areas at Nouryon discharge to a sump. There are no floor drains in the storage areas at Henkel.
Page 1

4. Are storage tanks and areas diked, contained, or otherwise constructed in such a way as to prevent harm tothe WWTP, especially from
spills or slugs? YES
Where do they go?
All storage tanks are diked or are located in areas that are protected by sumps at both Nouryon and Henkel. Any spills in the diked areas
would be reclaimed or pumped to storage tanks at Nouryon. Any storm water in the diked areas are manually pumped to a sump. Spilled
materials would be shipped offsite as hazardous or nonhazardous materials by Univar Solutions. Henkel also uses Univar Solutions.
5. Are process and storage tanks and pipes labeled? YES
6. How are off -spec raw materials, and products disposed or.
Nouryon: Republic picks up normal non -hazardous dumpster and one compactor; Univar Solutions, Charlotte, NC hauls drummed hazardous
and non -hazardous waste; Republic also hauls sludge from wastewater press, hazardous chemicals, floor sweeps and solids removed from
sumps. Henkel also subcontracts Univar Solutions for their hazardous waste removal. Manifests are maintained on file at the Nouryon facility.
7. When is the production area cleaned? Production area is cleaned daily and on each shift at both facilities.
8. Is the wastewater from cleaning the production area discharged to the POTW? YES
Wastewater from cleaning production areas, discharge to the sump and then to lagoon #1 for pretreatment.
9. What non -process wastewaters are discharged to POTW? Domestic waste is the only wastewater that is discharged directly to the POTW
without first being treated in the wastewater treatment system. Boiler blowdown, cooling tower, most stormwater from plant areas, and treated
water from superfund wells are discharged to the wastewater treatment system before being discharged to the POTW.
Section Comments:
• Area 2 sump (Tank 97) has diffused aeration and is checked for 1,2 dichloroethane prior to discharging to lagoon V. If the concentration
is > 210 ppb, the H2O is treated with diffused aeration prior to discharging to lagoon #1. The wastewater can also be treated with diffused
aeration in the "65K gallon tank" which holds approximately 70Kgallons.
• Production areas 1-4 can be sent to the 65K tank or to the adjacent spill tank especially during periods of heavy rainfall. There is also a
15-18K gallon "spill " tank adjacent to the 65K tank IU stated that the 65K tank has better blowers for air injection than compared to the
15-18 Kgallon spill tank
• The area 4 warehouse has a loading dock for shipping and contains mostly dry goods (Nouryon products). The Henkel products shipped
from this area are adhesives that have a very low viscosity. There are no dikes or floor drains in this area.
• All Henkel production areas (Hushpuppy; Saturn; HI01: high bay, low bay, storage area, tank farm, and Project Trout area) discharge to
one of two sumps: Saturn and HI01. H101 sump pumps to the Saturn sump and the Saturn sump is pumped to Area 4 sump at Nouryon.
• Stormwater drains at Henkel and Nouryon that do not drain to wastewater treatment system are directed to the onsite retention pond. The
pond outlet can be closed if a spill were to reach the stormwater system. The stormwater pond is checked on a regular basis by Nouryon
personnel. Nouryon is responsible for site stormwater via a NPDES Stormwater Permit.
PART I1- Plant Tour Section B - PRETREATMENT SYSTEM
Ask the operator to describe pretreatment system.
1. Does operator seem knowledgeable about the system? YES
2. Are all units operational? YES
All lagoons are now online. IU stated that approximately every 5 years the clarifier is scheduled for service. A new sludge tank has been
installed and the above ground clarifier has been re -coated.
3. How often does operator / maintenance person check system?
Daily -every shift, weekly, and monthly checks are performed. (Production staff covers 2"d and Yd shifts and vacations).
4. Is there an operator for each shift?
5. How and when is sludge disposed of?
Hauled offsite as needed by Republic.
YES
6. Is there a schedule for preventative maintenance? YES
Daily, weekly, and monthly. Repairs performed as needed.
Section Comments:
The superfund area pretreatment system discharges to lagoon #1. Defoamer (Foam-A-Tac 605) is being used. A daily check for the presence of
foam is being completed at a manhole located downstream of Pipe 01 (along outfall). An inspection log sheet is completed daily and maintained
for record keeping on -site.
An Authorization to Construct approval has been granted by the City of Salisbury on October 28, 2020 for the construction of a Ground Water
Pretreateatment System for additional groundwater remediation. IU stated that the planned projected timeframe for bringing the unit on-line
will be March 2024.

Nouryon: Republic picks up normal non -hazardous dumpster and one compactor; Univar Solutions, Charlotte, NC hauls drummed hazardous
and non -hazardous waste; Republic also hauls sludge from wastewater press, hazardous chemicals, floor sweeps and solids removed from
sumps. Henkel also subcontracts Univar Solutions for their hazardous waste removal. Manifests are maintained on file at the Nouryon facility.
7. When is the production area cleaned? Production area is cleaned daily and on each shift at both facilities.
Is the wastewater from cleaning the production area discharged to the POTW? YES
Wastewater from cleaning production areas, discharge to the sump and then to lagoon #1 for pretreatment.
9. What non -process wastewaters are discharged to POTW? Domestic waste is the only wastewater that is discharged directly to the POTW
without f rst being treated in the wastewater treatment system. Boiler blowdown, cooling tower, most stormwater from plant areas, and treated
water from superfund wells are discharged to the wastewater treatment system before being discharged to the POTW.
Section Comments:
• Area 2 sump (Tank 97) has diffused aeration and is checked for 1,2 dichloroethane prior to discharging to lagoon #1. If the concentration
is > 210 ppb, the H2O is treated with diffused aeration prior to discharging to lagoon #1. The wastewater can also be treated with diffused
aeration in the "65K gallon tank" which holds approximately 70Kgallons.
• Production areas 1-4 can be sent to the 65K tank or to the adjacent spill tank especially during periods of heavy rainfall. There is also a
15-18K gallon "spill" tank adjacent to the 65K tank IU stated that the 65K tank has better blowers for air injection than compared to the
15-18 K gallon spill tank
• The area 4 warehouse has a loading dock for shipping and contains mostly dry goods (Nouryon products). The Henkel products shipped
from this area are adhesives that have a very low viscosity. There are no dikes or floor drains in this area.
• All Henkel production areas (Hushpuppy; Saturn; H101: high bay, low bay, storage area, tank farm, and Project Trout area) discharge to
one of two sumps: Saturn and H101. H101 sump pumps to the Saturn sump and the Saturn sump is pumped to Area 4 sump at Nouryon.
• Stormwater drains at Henkel and Nouryon that do not drain to wastewater treatment system are directed to the onsite retention pond. The
pond outlet can be closed if a spill were to reach the stormwater system. The stormwater pond is checked on a regular basis by Nouryon
personnel. Nouryon is responsible for site stormwater via a NPDES Stormwater Permit.
PART II - Plant Tour Section B - PRETREATMENT SYSTEM
Ask the operator to describe pretreatment system.
1. Does operator seem knowledgeable about the system? YES
2. Are all units operational? YES
All lagoons are now online. IU stated that approximately every 5 years the clarifier is scheduled for service. A new sludge tank has been
installed and the above ground clarifier has been re -coated.
3. How often does operator / maintenance person check system?
Daily -every shift, weekly, and monthly checks are performed. (Production staff covers 2id and 3'd shifts and vacations).
4. Is there an operator for each shift?
5. How and when is sludge disposed or
Hauled offsite as needed by Republic.
YES
Is there a schedule for preventative maintenance? YES
Daily, weekly, and monthly. Repairs performed as needed.
Section Comments:
The superfund area pretreatment system discharges to lagoon #1. Defoamer (Foam-A-Tac 605) is being used. A daily check for the presence of
foam is being completed at a manhole located downstream of Pipe 01 (along outfall). An inspection log sheet is completed daily and maintained
for record keeping on -site.
An Authorization to Construct approval has been granted by the City of Salisbury on October 28, 2020 for the construction of a Ground Water
Pretreateatment System for additional groundwater remediation. IU stated that the planned projected timeframe for bringing the unit on-line
will be March 2024.

PART II - Plant Tour Section C - SAMPLING POINT(S) AND FLOW MEASUREMENT
Does an outside lab complete sampling? NO If yes, name of lab.
SIU performs all sampling. Pace Analytical and Waypoint Analytical Labs are contracted for all certified analyses and both labs provide pre -
preserved bottles to the SIU The SIU analyzes COD & TSSfor internal process control only.
2. If industry completes sampling, ask the industry representative to describe sampling procedures.
Comments: Samples are packed on ice in cooler and shipped the same day as collection. A temperature log is kept on the refrigerator, and used
for sample storage. The automatic sampler is iced during each sampling event and sample tubing is inspected and replaced as needed.
3. Is flow measurement equipment operational? YES
Comments: BW Allen maintains and calibrates the flow meter.
METER READING: 3488100
4. Is there a calibration log for the flow meter? YES
Section Comments:
Calibration log for the flow meter is submitted with semiannual reports.
PART III - EXIT INTERVIEW
Review monitoring records and other SIU records required by IUP.
Are files well organized?
2. Are sample collection / chain -of -custody forms filled out properly?
3. Do results in riles agree with reports sent to POTW?
YES
YES
YES
4. Who has authority to shut down production should a spill or slug discharge occur?
Any operator, supervisor, or manager on duty, and Chris Fleming.
5. How does SIU inform employees of whom to call at POTW in case of spill / slug?
There is annual training in September for all employees during Safety Days when the plant is shut down for several days to focus on training.
Note: Last in-house training conducted September 27, 2023.
Company also conducts training with Salisbury Fire Dept. HAZMAT Teams --with RCRA training also being conducted. In addition, company
has an emergency operator call back procedure and has recently installed surveillance cameras for operations to monitor lagoons.
6. Slug / Spill Control Plan Required? YES
Last update submitted: August 9, 2023
7. Is SIU implementing slug / spill plan? YES
Review procedures. Spill kits are located throughout the plant and are checked regularly and documented on weekly inspection sheets. They
have facility -wide notification procedures in place for larger spills and an on -site spill response team.
Section Comments:
Spills or slug discharges can be diverted to the 65K gallon tank if needed.
