Arauco North America, Inc. is submitting this letter in response to the Division of Water Resources' request
on June 17, 2021 related to the minor modification submitted for the facility's Non -Discharge permit
(WQ0003396).
Arauco North America, Inc. has determined, with concurrence from members of the North Carolina
Division of Water Resources, to maintain the site Non -Discharge permit (WQ0003396), despite cease of
spray irrigation field use as a means of treated effluent application, as treated wastewater effluent is now
sent to the City of Sanford Wastewater Management Facility according to Industrial User Permit 000042,
Below is the facility's response to each requested item:
A. Cover Letter: The facility plans on ceasing spray irrigation for the foreseeable future, and has not
used spray irrigation as a method of wastewater disposal since prior to wastewater pipeline
connection with the City of Sanford on November 6, 2020. The facility determined Loblolly Pines
would provide appropriate coverage and hydrologic uptake from natural precipitation (rainfall,
etc.) and does not believe additional means of irrigation will be necessary for the growth of these
trees. The site reviewed the annual soil analysis completed in February 2021 (see attached), as
well as historical groundwater monitoring, and consulted with faculty from North Carolina State
University's Environmental Engineering school to ensure feasibility of this species under these
groundwater, hydrologic, and soil conditions. The facility wishes to remove and possibly sell the
existing irrigation equipment since the spray irrigation activities will be ceasing for the foreseeable
future. The facility does not wish to remove the fields from the permit, as the site would like to
retain the ability to spray if the need arises in the distant future. The site also believes that the
inclusion of Loblolly Pines in the area will improve the groundwater quality, soil stability, and
erosion control properties. The site requests the ability to use either Loblolly Pines or other
suitable vegetative coverage as we currently do (ex. Bermuda grass).
C. Application: The facility does not intend to maintain the irrigation system or equipment for future
use and wishes to remove and/or sell it at this time. Should the site decide to implement spray
irrigation again, new equipment, appropriate to the crop cover and subject to applicable

operation and maintenance conditions and requirements, would be purchased and approved by
the Division of Water Resources prior to any irrigation activities.
N. Operation and Maintenance (O&M) Plan: Please see attached for proposed Operation and
Maintenance Plan with edits in red and removed information highlighted yellow. Should the site
decide to use Loblolly Pine for crop cover, the crop would be planted and maintained per
recognized forestry practices including harvesting and thinning of crop every few years to allow
for health and growth of the trees. A third party has been utilized to advise on accepted standards
for this species. If the site determines that it would prefer not to plant trees in the area, suitable
vegetative coverage will be continued in the area as it currently is with Bermuda grass, or another
comparable crop.
P. Additional Documentation (Existing Permit): As mentioned in the sections above, the facility
does not intend to maintain the irrigation equipment onsite. Any crop will rely on rainfall for
hydrologic needs. The facility requests that existing condition 111.7 of the permit be revised to
remove this requirement or require it only during periods were there is operational irrigation
equipment onsite. A Responsible Authorizing official from the company will sign an annual
certification that no irrigation activities have occurred during the previous year.
Attached you will find the most recent annual soil analysis for spray irrigation zones completed by the
site, as well as the revised proposed Operations and Maintenance (O&M) Plan.
If you have any questions, please contact Savannah Carroll, Regional Environmental Manager, at (919-
545-5848) or (843-544-3025).
Sincerely
P ". &_'

I. System Description
Wastewater Management System:
For the operation of wastewater storage lagoon (Pond #5) modifications consisting of:
Installation of an earthen lagoon divider to separate Pond #5 into "Side C" — 6.79 million
gallons (MG) — to store rainwater, and "Side D" — 6.73 MG - to store process wastewater
from the existing moulding and MDF mill; one 48.1 GPM mill water make pump (can
also transfer water from lagoon "Side C" to "Side D" if necessary)
For the continued operation of a wastewater pretreatment facility consisting of.
A 13.52 MG clay lined wastewater storage lagoon (Pond #5); a grit settling pond (Pond
#4) to receive wastewater from Pond #5, made up of plant wastewater and wash down
water; a grit settling pond (Pond #1); an aerobic treatment pond (Pond #2) to receive
untreated effluent from the domestic wastewater sump fed by a 2" 29 GPM Zoeller 292
Submersible Sewage Pump, in addition to the process wastewater from Ponds #1 and 4;
secondary settling pond (Pond #3) to receive the wastewater from Pond #2; a pump
station with two 4" Gorman Rupp T4A3s-B 200 GPM pumps to transfer treated effluent
from Pond #3 to the City of Sanford Wastewater Management Facility via Industrial User
Permit 000042.
Eight irrigation zones with total 333.85 acres of crop cover previously used for spray
irrigation treatment and now populated with Loblolly Pines or other crop cover for
groundwater improvement and suitable coverage and erosion control in case of future
irrigation need.
II. Operational Function
Any blowdown water is taken to the dirty side of Pond #5, "Side D", treated though
Ponds #2-4, and disposed of via pipeline to the City of Sanford Wastewater Management
Facility. Domestic wastewater is tributary via pipeline to the City of Sanford Wastewater
Management Facility.
III. Required System Management
Tanks: Inspect for leaks or overflow, take out of service and repair as necessary.
Pipes: Inspect for leaks, take out of service and repair as necessary.
Pumps: Grease, change seals, repair leaks, and replace when necessary.

Ponds: Inspect base of Ponds # 1-4 regularly, mow and maintain surrounding areas, clean
screen between Pond 44 and Pond #2 as necessary and check level gauge for adequate
freeboard regularly.
Previous Irrigation Zones: Loblolly Pines or other crop coverage located in previous
irrigation zones are maintained through natural processes and precipitation and in
accordance with recognized forestry and industry practices. A third party forestry unit
manages the maintenance and harvesting needs of the Loblolly population to ensure
proper maintenance and health of the system. Any other utilized cover crop is maintained
as necessary. All prior irrigation equipment has been removed and any new equipment
brought onsite for use of spray irrigation in these areas is subject to state regulated
maintenance requirements and established best management practices.
*Moncure site maintains a work order system for mechanical and electrical malfunctions
as well as repairs. If repairs are needed, add a work order to the work order system.
IV. Sludge Manazement
Several types of "sludge" or "residuals" are generated in the systems as described
previously in the system description. Listed below are the means by which each of the
sludges are to be handled and disposed.
Domestic Sludge: generated in the domestic sump that temporarily holds domestic
wastewater. These solids are taken to the City of Sanford by a septage hauler as needed.
Procedure: Refer to Arauco Residuals Management Plan Section 1.
Process Wastewater Sludge: that is washed or emptied into "Side D" of Pond #5. These
solid consist entirely of wood residuals from the MDF plant.
Procedure: Refer to Arauco Residuals Management PIan Section III.
V. Health and Safety Measures
Required PPE when on Moncure's Site Includes:
• Steel/Composite Toe Footwear
• Hard Hat
• Safety Glasses
• Hearing Protection
• Hi -Visibility Clothing
