A. Cover Letter 1. See attached lab analysis results for Boiler Water Blowdown from MDF and Cooling Water Tower Blowdown from Particleboard. 2. See attached Wastewater Spray Irrigation System Management Plan for recommended irrigation rate for the fields. In addressing B.1. Arauco will be retiring the spray system for field 10. This would eliminate 2,572,896 gallons of water per year and change the daily loading to 39,525 gallons per day. 3. Arauco would like to remove the closed -loop treatment systems and reclaimed water systems from the permit but keep the following pieces of equipment from these systems to be repurposed as a pretreatment system for future connection to the City of Sanford wastewater pipeline. The equipment to be kept is as follows: • 1 500-gallon calcium hydroxide mix tank with agitator and a 3.8 gpm metering pump • 1 4,000-gallon scrubber conditioning tank with agitator and dual (2) 21.3 gpm tank transfer pumps • 1 500-gallon screen water buffer tank with dual 129.6 gpm transfer pump • 1 100,000-gallon screened water tank with agitator and dual 119.6 gpm transfer pumps • 1 500-gallon "overflow' tank with dual 4.4 gpm transfer pumps • A flocculent and coagulant dosing system prior to the screw press • 1 Huber screw press • 1500-gallons screw press buffer tank with agitator and dual 153.6 gpm screw press out feed pump • 3 340-gallon storage tanks and a flocculent, coagulant, and neutralizer dosing system prior to one pipe flocculator • 1 dissolved air floatation (DAF) clarifier • 1 4,000-gallon sludge tank with mixer and dual 6 gpm sludge tank transfer pumps • A flocculent and coagulant dosing system to serve 1 Huber sludge screw press with conveyor to send dewatered and pressed wood chip sludge to the fuel pile • 1 500-gallon sludge screw press buffer tank with agitator and dual 9 gpm buffer tank transfer pumps • 1 500-gallon DAF outfeed buffer tank with dual 188.8 gpm out feed transfer pimps • 1 30,000-gallon mill water storage tank • 2 87.1 gpm mill water transfer pumps (#1 and #2) • 2 squeeze water screens • 1 6,800-gallon squeeze water tank with agitator • 2 8.2 gpm plug screw flush water pumps • 2 32.7 gpm excess squeeze water pumps • 1 squeeze water heat exchanger • 1 9,000-gallon squeeze water storage tank • 2 30.9 gpm squeeze water pumps • Various pumps (not individually listed) for transporting wastewater from various MDF mill process areas to the wastewater treatment system • Continued operation of wastewater storage lagoon (Pond #5) • Continued operation of a 126,000 gpd wastewater treatment and surface irrigation facility 4. Arauco would like to change the flow limit to a flow measurement. We would like to measure the total influent flow at Pond 3 and the effluent flow directly after Pond 3. If the influent flow minus the effluent flow is a negative value, this would signify more water is being treated than entering the system and be complying with our permit. We would like this number to be calculated on a monthly average. B. Site Map 1. Arauco has elected to stop using the center pivot spray irrigator on field 10 to avoid the potential of wastewater entering the wetland that is within close proximity to field 10.

Preliminary Information Occasionally the irrigation system has experienced ponding and poor drainage in the irrigation fields. As a result, Arauco has engaged the use of pump and haul equipment to minimize irrigation events and prevent the ponding conditions which are a permit violation. The pump and haul activity has been permitted and all available information indicates that pump and haul will be available for the foreseeable future. Irrigation fields have been stressed in the past with heavy hydraulic and sodium loading. The site is not capable of accepting the volumes allowed by the permit of 52 inches per year for fields 02, 03, 06, 07, 08, 09, and 10. Field 04 and 05 presently have an annual hydraulic limit of 12.74 inches. Hourly rates in the permit range from 0.20 to 0.60 inches per hour. These rates are not being exceeded and the actual rate will be discussed below. It is a function of the irrigation pivot speed, which is set at 100% and thus offering the lowest rate possible. Tables below will offer recent calibration data supporting the rates. The fields have been sprigged to hybrid bermudagrass and are in very good shape overall. In past years, row crops have been attempted with mixed results. Historically, fields 02, 03, and 10 have been more sensitive to wetness and ponding than the others. These three fields still have minor ponding and bare areas but the extent is not significant. Fields 06, 07, and 08 have some very minor areas of wet soils and bare spots. Fields 04 and 05 have the best topography to shed surface water. Past assessments from 2016 and prior have shown poor crop health and large areas of bare ground. Compared to recent history, the ground cover is excellent and offers great erosion control and infiltrative capacity. The crop is hybrid bermudagrass with mixed areas of yellow nutsedge and minor areas of crabgrass, johnsongrass, and a few mixed broadleaf weeds. As required by the permit, a calibration was performed several years ago. That report and details are available upon request. The key issue relevant to this project is the irrigation rate, as that is critical to assessing runoff and ponding potential. The calibration data are presented in Table 1 below. Table 1 - Calibration Data- irrigation rates FIELD NUMBER MEASURED APPLICATION RATE in/hr PERMITTED RATE (in/hr) COMPLIANT? 02 0.20 0.60 YES 03 0.23 0.60 YES 04 0.13 0.20 YES 05 0.14 0.20 YES 06 0.20 0.35 YES 07 0.20 0.60 YES 08 0.23 0.60 YES 09 0.15 0.60 YES 10 0.16 0.60 YES All application rates are well under the permitted rate. The system has been operated for years and the present application rates have proven effective and conservative enough for the soils, given the proper irrigation conditions. This will be discussed more in the irrigation scheduling section. Sites have gentle topography with slopes of 0 to 6 percent, but mostly 1-2 percent. This gentle slope condition enhances infiltration potential. Fields 04 and 05 have the best topography to shed natural surface water. Further, they also have the lowest application rate. These fields should be prioritized for irrigation when conditions are not yet suitable for irrigation on other fields. Irrigation Scheduling The key goal to any non -discharge irrigation system is operation to prevent ponding and runoff. Permitted rates as shown above are acceptable for the soils and site topography. Annual limits will not be approached, and have not been for many years. The discussion below is based on the soils at the site. In brief, the soils have a sandy loam and fine sandy loam surface texture 8-10 inches thick. Below this surface layer the soils are clay loam and clay. The subsoil layer has experienced some clay dispersion over the past, and thus soil structure in the subsoil is weak to non-existent. This affects the deep permeability rate of these soils, and therefore a very slow and conservative drainage rate will be assumed. The irrigation scheduling discussion below will be based upon the top 8 inches of soil, and its wetting/drying cycles. Irrigation volumes will be discussed in terms of irrigation depth (inches) per event. The operator can assess what total wastewater volume may be potentially irrigated based upon these conditions. No daily or weekly volume can be developed as all irrigation events are strictly a function of weather conditions in the 4-8 days prior to a selected irrigation event. Also included is a water balance developed using local weather data and the drainage factor discussed above. The water balance is a theoretical tool that can give estimated volumes of irrigation potential. Day-to-day operation will be based upon the checkbook irrigation scheduling method discussed below Checkbook Method of Imaation Schedulin¢ Irrigation scheduling is best performed by close monitoring of the site conditions, weather conditions, and maintaining detailed weather and application records. This method is referred to as "the checkbook method". It starts with a known point of soil moisture, and works off of inputs and losses over time, typically per day. Inputs are rainfall and irrigation events. Losses are evaporation, transpiration, and deep soil drainage. Rainfall and irrigation events will be measured. Losses will be calculated based on local weather historical data and based on the soil conditions. For purpose of this evaluation, soil drainage will not be measured but estimated on a very conservative basis as described above. All fields will be defined as one zone as site conditions are similar, with these noted exceptions: 1) Fields 02, 03, and 10, due to topography and landscape position, are the most sensitive to ponding. These three fields, for purpose of this report, are grouped into Zone A. 2) Fields 06, 07, 08, and 09 are in good shape and have similar properties. These four fields, for purpose of this report, are grouped into Zone B. 3) Fields 04 and 05 have the best topography potential to shed natural rainfall and these will more readily accept irrigation events. These two fields, for purpose of this report, are grouped into Zone C. Since the irrigation system applies approximately 0.2 inches of wastewater per irrigation event with one full pivot run- i.e. the full 360-degree circle, the soils need the ability to accept this irrigation depth without ponding. The table below (Table 2.) will set irrigation events based on weather conditions. The assumptions are: 1) Starting point is soil saturation. This can be assumed after any irrigation event or after any rainfall event at least 0.3 inches or greater in depth. Rainfall amounts less than 0.3 inches should be accounted for and prorated. 2) The maximum water holding capacity in the top 8 inches of soil is 2.4 inches of water. 3) That a decent cover crop is maintained on the fields. This will enhance evapotranspiration. Table 2. Irrigation Events after a saturation event. MONTH LAG TIME' BEST CONDITIONS2 POOR CONDIITONS3 May -Sept 4 days 3 days 6 days April, October 1 6 days 4 days 8 days Nov -March 8 days 6 days 10 days 1-For Zone C fields, reduce by one day. For Zone A fields, add 2 days. 2- Best Conditions means full sun with some wind and low humidity. In the winter, best conditions also means that the winter overseed (ryegrass) has good coverage. 3- Poor Conditions means overcast with high humidity and low wind. The DWR monthly NDMR record keeping forms is a good tool to use to track irrigation events and rainfall, and could be used as the management tool to record data and schedule irrigation events. Water Balance An attached water balance was performed to estimate average potential irrigation for this site. It is not intended to change the permit or override any permit conditions. It is based on a worst year in five for weather conditions (also called 80te percentile weather data). Therefore, it can be used as a general planning tool to estimate long-term irrigation potential. Although the water balance shows monthly irrigation amounts, this tool should not be used for irrigation scheduling. The checkbook method above, with tracking of rain and irrigation events, is the main tool to be used. Assumptions for this water balance are: 1) Drainage of 0.1 for the slowly permeable subsoil 2) Most conservative drainage factor of 0.04 applied. 3) 50,000 gallons per day flow 4) All fields treated the same The water balance shows that 16.8 inches annually could be applied, on average. However, make sure that the permit limits for fields 04 and 05 (12.74 inches per year) are not exceeded. Table 3.

SUMMARY COMMENTS Present irrigation rates are acceptable for this system and soils. Operators are cautioned to run only one irrigation cycle and not to reverse pivots, resulting in application depths exceeding 0.2 inches per event. The above summaries are based on presumed weather conditions, and actual operation may be potentially higher or lower than the figures stated. Using the water balance approach, an average daily flow of 46,574 gallons is permissible. Detailed irrigation scheduling such as using the checkbook method may allow enhanced irrigation volumes. Maximum irrigation potential can be realized with 7-day operation. An irrigation event should not take place if a rainfall event of 0.5 inches or higher is predicted within 24 hours after the irrigation event. There may be vulnerable areas in each field where shallow subsurface drainage allows water to weep out at low areas. These must be monitored before and during each irrigation event. These areas may prevent the site from drying as predicted with the above related comments. We appreciate the opportunity to assist you.
