L, Q NORTH CAROL.INA DEPARTMENT OF. ENVIR0,N,ME1,4T`AND NATURAL RF-SOURCES FAYET T IE'VILL-E F!EGIONAL OIFFICE June 10, 1998 MEMORANDUM TO: Randy Kepler Non -Discharge Permits & Engineering FROM: Grady Dobson Fayetteville Regional Office C/ Y g SUBJECT: Permit Amendment/Renewal Permit No. WQ0000464 Mountaire Farms, Inc. Lumber Bridge Plant Lumber Bridge,'North Carolina Robeson County On May 6, 1998, this office received a permit amendment/renewal package for the Mountaire Farms, Inc., Spray Irrigation Facility. On May 13, 1998, I visited the Mountaire Farms' facility to verify visually what was proposed in the amendment package. I met with John Wren and Robert Jackson on this date. The amendment includes a 275,000 gallon cast -in -place concrete flow equalization basin with floating aeration and an 18" diameter gravity line from the offal room's secondary screens to the proposed equalization basin. A new feed forward pumping station is proposed to convey the wastewater from the equalization basin to the new treatment (Pretreatment - DAF Unit). Also, to be included in this amendment is a wash down pump to wash down foam -solids in the equalization- basin. The above amendments will enhance the wastewater quality to ultimately be spray irrigated and I recommend that they be allowed in the amendment to the existing permit. The following items are requested to be considered for modification per Company request in the May 5, 1998 letter: l) Please change the name in this permit to Mountaire Farms, Inc., in all appropriate locations in the permit.. 225 GREEN STREET, SUITE 714, FAYETTEVILLE, NORTH CAROLINA 28301-SO43 PHONE 910-486-1541 FAX 910-486-0707 AN EQUAL OPPORTUNITY / AFFIRMATIVE ACTION EMPLOYER - SO% RECYCLED/10% POST -CONSUMER PAPER MEMO -Randy Kepler Page 2 June 10, 1908 (2) Please modify permit to state the maximum flow of 1.75 MGD. (3)' Please modify permit to read as requested which will be in place after construction. (4) ► his item is for clarification that another permit amendment will not be necessary if additional pumps are required to handle higher flows after the new expansion is complete. As far as I am concerned, bigger pumps or more pumps can be added to handle the permitted flow without a permit amendment. Should expansion increase beyond the permitted capacity, then a permit amendment would be necessary. (5) It is my recommendation that this permit, when amended, be issued for a 5 year term. It will be well into 1999 before all the treatment units, spray acreage, etc., will be operational and to require a permit amendment prior .to utilizing the new units does not seem practical. They have spent millions to improve a bad situation and to charge another $400.00 just to renew the permit is not justified for less than a 6 month period! (6) Condition I (3) - Their proposal is logical to me. They want to let the lagoons naturally dewater (evaporate) and at some point, dispose of the sludge and close out the existing lagoons. Condition I (3) needs to stress that the old lagoons need to be closed out in a prompt manner once the new system is on line and that a land application of sludge permit or an official acceptance from a landfill to handle the sludge is required. I think they understand this, but this Condition is unclear to them. (7) Condition I (6) - This condition is unclear to them. This new system will allow more renderable product than ever before. A statement that all non- renderable sludge will require a land application of sludge permit or verification of acceptance from an approved landfill would be necessary under our NCGS 143-215.1 will suffice. (8) Their statement for Condition H (11) seems to address the condition you indicated in the most recent permit. I guess they need verification that they have proposed what we require.

' Lumber Bridge, North Carolina Dear Mr. Colson: Mountaire Farms received its revised spray irrigation permit, issued March 4, 1998, and has initiated construction of the treatment improvements. We would like to make several changes to the design documents submitted with our permit application. The,- design- of the treatment system has been changed to eliminate conversion of the., existing grease trap into a flow equalization basin and then pumping from the grease trap to the new treatment system.. Instead we desire to .construct a new 275,000 gallon cast -in -place concrete flow equalization basin with a, floating aerator. An 18 inch diameter gravity line will be constructed from the offal room secondary screens to the new, flow, equalization basin. The basin -will be located between existing lagoon No. 3 and the new treatment building. A.new feed forward pumping station will be constructed 'next to the. flow equalization basin. to convey wastewater . to the new treatment building. A wash down pump will be provided as partof the spray irrigation pumping station. This will supply treated water to wash down the flow equalization basin.. Originally, we had intended to construct the new flow equalization, basin after the lagoons were closed. - .The new basin will provide greater ..flexibility in the operation of the system - and the elimination of the existing grease trap will improve the movement of truck traff c. , Mountaire Farms of Delmarva, Inc. • �` Mountaire Farms of North Carolina, Inc.

We request that the effective date be extended so we do not have to submit a "permit renewal ' application in approximately six months. If additional information isneeded to extend -the -effective date of the permit please advise. ' 6. Condition I.3. Please clarify the' intent of this condition. It has been our:intention that when the existing lagoons are removed from'service they will treat -and digest,'.. the remaining wastewater and that in.two to three years the remaining material will be removed. The 'niaterial will be more stable then and be easier to dispose. The necessary permits will be ,obtained' before the material is removed -.and disposed The lagoons will then be filled and' final closure performed. Any.storm water in the lagoons will be pumped, treated and land applied by irrigation. T,he . existing DAF/grease trap will be removed at the completion" of construction of the new system. We trust this -schedule is acceptable.. 7. Condition L6.. -The fats, oils and greases removed from the treatment system are intended to be sent to a rendering facility. The same- facility that presently renders offal from the -facility will also render the material recovered from the treatment system. Please clarify this condition to allow. the -material to be rendered: The only sludge produced by,the treatment system is from the sanitary plant. Sludge from the sanitary system willcontinue to be,handied by a licensed hauler. i Mr. Kim Colson DENR Page 4 8. Condition IL 11: - Please clarify this condition. Flow meters will be installed prior to each DAF. These ".two meters will measure the total flow from the processing operation, including the oil and grease to be removed-bylhe DAR A meter, -will be . installed after the "Sorin Treatment clarifier and prior to the storage lagoon. This meter will measure the-- total process and sanitary flows into the lagoons. Two flow meters will be installed in.the spray irrigation transmission lines. These two ` flows meters will measure total flow � discharged from the lagoon including rainfall and any water pumped from the existing lagoons. Finally, there is a ,separate sanitary flow meter that will measure, the quantity of sanitary effluent, pumped to the storage lagoon.- It is recommended that the meters on the -spray ,irrigation' transmission lines be used to fulfill Condition III.3.

Based on our site evaluation B, and its proposed spray acreage of 7.72 acres are unsuitable. B, shall not be included as usable acreage. Land Use: The land is presently owned by Mountaire Farms of North Carolina and it is currently adjacent to permitted spray acreage under Permit No. WQ000484. Description of Proposed System: This was discussed in Part II 2(d). Land Limiting Constituent Analysis: The subject facility is currently permitted for 570,000 GPD of industrial poultry processing wastewater for land application - spray irrigation onto 151.83 acres of Coastal Bermuda grass with a winter small grain cover crop. The Company proposes to expand the existing processing capacity by adding another kill shift and a cleanup shift. This proposed expansion will increase the flow of processing wastewater from 570,000 gpd to 1.11 med. The proposed expansion will include major improvements to the wastewater treatment system. The major improvements proposed are as follows: (1) Flow Equalization (2) Construction of two new DAF units for Nitrogen Removal (Sorin Treatment Units). The DAF Units will include a building (spare parts & chemical storage), electronic/monitoring controls, miscellaneous plumbing and .electrical work. (3) Construction of 19.79 MG aerated storage lagoon. The net storage volume will be • approximately 18.61 MG. The lagoon will be lined with 30 mil synthetic liner which should meet permeability requirements for storage and waste treatment lagoons. PART III - OTHER PERTINENT INFORMATION (continued): The addition of 130.31 acres for wastewater application. These proposed major treatment improvements will improve the efficiency of wastewater management and will control the quality of wastewater to be land applied. These improvements will give the Company greater flexibility in wastewater management. The proposed wastewater treatment methods will improve effluent quality and the additional acreage will allow a resting period for tighter soil types which will improve maintenance and management. Based on the water balance included in this application amendment package, there is adequate appropriate land to assimilate the proposed wastewater expansion. Based on data from pilot studies for the DAF Unit, hydraulics seems to be the limiting factor. The nitrogen or (PAN) loading and the metals indicate relatively low levels. Mountaire Farms' personnel will monitor nutrient loadings to assure permit compliance. The application package description of the proposed irrigation methods appear reasonable. Crop Management Plan: Crop management will consist of planting Coastal Bermuda grass on proposed fields and monitoring the Coastal Bermuda on.existing permitted acreage along with planting of winter overseed crop with technical assistance from Robeson County Agricultural Extension Services. The technical assistance will assure crop is managed properly. Records Mana ement: All records are the responsibility of Mountaire Farms of North Carolina. Accessibility: All property for existing and proposed land application acreage is owned by the Company and access is controlled by gates and chains. Unauthorized access by the public would be trespassing. PART IV - EVALUATION AND RECOMMENDATIONS It is the recommendation of this office that the subject application be processed and Permit No. WQ000484 be amended. In Part III 4. Soils Information, it is recommended that the field zones listed in the table with he application rates be written as a special condition. This will help records management for the Company and the compliance concerns. for the Division. In the existing Permit, Part III 3, various permit parameters are required to be analyzed monthly. • It is -recommended that this condition remain. In Part I1I 5., quarterly cleaning of the existing air flotation/grease trap is required. It is recommended that this, remain until such time as the new DAF unit is on line. Once the new DAF is operating, the existing system will be removed. A sentence stating that would be sufficient along with written documentation to the FRO stating completion of new units.

Some of the buffers specified.above may not have been included in previous permits for this waste treatment and disposal system. These buffers are not intended to prohibit or prevent modifications, which are required by the Division, to improve performance of the existing treatment facility, These buffers do, however, apply to modifications of the. treatment and disposal facilities which are for the purpose of increasing the flow that is tributary to the facility. These buffers do, apply to any expansion or modification of the spray irrigation areas and apply. in instances in which the sale of property would cattsc any of the buffers now complied with, for the treatment and disposal facilities, to be violated. The applicant is advised that any modifications to the existing facilities will require a permit. modification. 6: The spray field expansion shall not be under -drained, Areas subject to ponding must be excluded from irrigation. 7. Ponding of wastewater on any spray irrigation areas will indicate failure of the treatment and disposal system and shall be sufficient reason for the Division of Water Quality to require remedial action. 8. After the initial operation of the pump stations and force mains for the infiltration galleries, Mountaire Farms will perform a test to simulate. a power failure. This test shall determine the time interval between pump shut down, high level alarms and the rate at which the wet well and groundwater levels reach unacceptable levels. Should this time interval be. shorter than the observed power outages reported by CP&L then Mountaire shall install an emergency generator for the.pump stations. LI. ,RATI `.D 1AYN CE iR ME S . .1..

The "monthly average discharge" is defined as the total mass of all daily discharges sampled and/or measured during a calendar month on which daily discharges are sampled and measured, divided by the number of daily discharges sampled and/or measured during such month. It is therefore, an arithmetic mean found by adding the weights of the pollutant found each day of the month and then dividing this sum by the number of days the tests were reported. The limitation is identified as "Monthly Average" in Part I of the permit b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled and/or measured during the calendar week (Sunday - Saturday) on which daily discharges. are sampled and measured, divided by the number of daily discharges sampled.and/or measured during such week. It is, therefore, an arithmetic mean found by adding the weights of pollutants found. each day of the week and then dividing this sum by the' number of days the tests --vere reported. This limitation is identified as "Weekly Average" in Pan I of the permit. .. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during a calendar day. If only one sample is taken during any calendar day the weight of pollutant calculated from it is the "maximum daily discharge." This limitation is identified as "Daily Maximum," in Part I of the permit. d. The "average annual discharge" is defined as the total mass of all daily discharges sampled and/or- measured during -he calendar year on which daily discharges are sampled and measured, divided by the number of daily discharges sampled and/or. measured during such year. It is, therefore, sr; arithmetic mean found by adding the weights of pollutants found each day of the year and then dividing this sum by the number of days the tests were reported. This limitacc•n. is defined as 'Annual Average" in Part I.of the permit. PART I Section B. Schedule of Compliance 1. The permittee shall comply with Final Effluent Limitations specified for discharges in accordance with the following schedule: Permittee shall comply with Final Effluent Limitadons by the effective date of the permit unless specified below. 2. Permittee shall at all times provide the operadon and maintenance necessary to operate the existing facilities at optimum efficiency. 3. No later than 14 calendar days following a date identified in the above schedule or compliance, the permittce shall submit either a report of progress or, in the case of specific actions being required by identified dates, a written notice of compliance or noncompliance. In the latter case, the notice shall include the cause of noncompliance, any remedial actions taken, and the probability of meeting the next schedule requirements. Part I I " Page ? of 14 6. Concenndon '\1eag•.:rement The "average monthly concentration," other than for fecal colifcrm bacteria, i,s the sum of the concentrations of all daily discharges sampled and/or measured during a calendar month on which daily discharges are sampled and measured, divided by the number of daily discharges sampled and/or measured during such month (arithmetic mean of the daily concentration values). The daily concentration value is equal to the concentradon of a composite sample or in the case of grab samples is the arithmedc mean (weighted by flow value) of all the samples collected during that calendar day. The average monthly count for fecal coliform bacteria is the geometric mean of the counts for samples collected during a calendar month. This limitation is identified as "Monthly Average" under "Other Limits" in Part I of the permit. The "average `' eekly concentration,"other than for fecal coliform bacteria, is the sum of the concentrations of all daily discharges sampled and/or measured during. a calendar week (Sunday/Saturday) on which daily discharges are sampled and measured divided by the number of daily discharges sampled and/or measured during such week (arithmedc mean of the daily concentration values). The daily concentration value is equal to the contents ion of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples collected during that calendar day. The average weekly count for,fecal coliform bacteria is the geometric mean of the counts for samples collected during a calendar week. This limitation is identified as "Weekly Average" under "Other Limits" in Part I of the permit. c. The "maximum daily concentration" is the concentration of a pollutant discharge during a calendar day. If only one sample is taken. during any calendar day the concentration of pollutant calculated from it is the "Maximum Daily Concentration". It is identified as "Daily Maximum" under "Other Limits" in Pan I of the permit. d. The "average annual concentration," other than for fecal coliform bacteria, is the sum of the concentrations of all daily discharges sampled and/or measured during a calendar year on which daily discharges are sampled and measured divided by the number of daily discharges sampled and/or measured during such year (arithmetic mean of the daily concentration values). The daily concentration value is equal to the concentradon of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples collected during that calendar day . The average yearly count for fecal coliform bacteria is the geometric mean of the counts for Samplescollectedduring a calendar year. This limitation is identified as "Annual Average" under "Other Limits" in Pan I of the permit. e. The "daily average concentration" (for dissolved oxygen) is the minimum allowable amount of dissolved oxygen required to be available in the effluent prior to discharge averaged over a calendar day, If only one dissolved oxygen sample is taken over a calendar day, the sample is considered to be the "daily average concentration" for the discharge. It is identified as "daily average" in the text of Part I. f. The "quanerly average concerttndon" is the average of all samples taken over a calendar qu rter. It is identified as "Quarterly Average.Limitation" in the text of Pan I of the permit. g. A calendar quarter is defined as one of the following distinct periods: January through I`larch, April through June, July through September, and October. through December. Pan II Page 3 of 14 7. Other Measurements a. Flow, (MGD): The flow limit expressed in this permit is the 24 hours average flow, averaged monthly. It is determined as the arithmetic mean of the total daily flows recorded during the calendar month. b. An "instantaneous flow measurement" Iis a measure of flow taken at the time of sampling, when both the sample and flow will be representative of the total discharge. . c. A "continuous flow measurement" is a measure of discharge flow from the facility which occurs continually without interruption throughout the operating hours of the facility. Flow shall be monitored continually except for the infrequent times when there.may be no flow or for infrequent maintenance activities on the flow device. a. Composite Sample: A composite sample shall consist of: (1) a series of grab samples collected at equal time intervals over a 24 hour period of discharge and combined proportional to the rate of flow, measured at the time of individual sample collection, or (2) a series of grab samples of equal volume collected over a 24 hour period with the time intervals between samples determined by a preset number of gallons passing the sampling point. Flow measurement between sample intervals shill be determined by - use of a. flow recorder and totalizer, and the present gallon interval between sample collection fixed -at no greater than 1/24 of the expected total daily flow at the treatment system, or (3) a. single, continuous sample collected over a 24 hour period proportional to the rate of flow. In accordance with (1) above, the time interval between influent grab samples shall be no greater than once per hour, and the time interval between effluent grab samples shall be no greater than once per hour except at wastewater treatment systems having a detention time of greater than 24 hours. In such cases, effluent grab samples may be collected at time intervals evenly spaced over the 24 hour period which are equal in number of hours to the detention time of the system in number of days. However, in no case may the time interval between effluent grab samples be greater than six(6) hours nor the number of samples less than four (4) during a 24 hour sampling period. b. Grab Sample:. Grab samples are individual samples collected over a period of time not exceeding 15 minutes; the grab sample can be taken manually. Grab samples must be representative of the discharge or. the receiving waters. 9. Calculation of Means Arithmetic Mean: The arithmetic mean of any set of values is the summation of the individual values divided by the number of individual values. Geometric .'vican: The geometric mean of any set of values is the Nth root of the product of the individual values where Nis equal to the number of individual values. The geomeric mean is equivalent to the antilog of the arithmetic mean of the logarithms of the individual values. For purposes ,of calculating the geometric mean, values of zero (0) shall be considered to be one (1). Part 11 Page 4 of 14 Weighted by Flow Value: Weighted by flow value means the summation of each concentration times its respective flow divided by the summation of the respective flows. 10. Calendar Day A calendar day is defined as the period from midnight of one day undl midnight of the next day. However, for purposes of this permit, any consecutive 24-hour period that reasonably represents the calendar day may be used for sampling. A hazardous substance means any substance designated under 40 CFR Pan 116 pursuant to Section 311 of the Clean WaterAct. 12. Toxic Pollutant A toxic pollutant is any pollutant listed as toxic under Section 307(a)(1) of the Clean Water Act. SECTION B. GENERAL CONDITIONS 1.

Proper operation and maintenance also includes adequate laboratory controls and appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilides or similar systems which are installed by a permittee only when the operation is necessary to achieve compliance with the conditions of the permit. It shall not be a defense for a permittee in aii enforcement action that it would have been necessary to halt oi• reduce the permitted activity in order to :naintain compliance with the condition of this permit. 4. Bypassing of Treatment Facilities a: Definidons (1) "Bypass" means the known diversion of waste streams from any portion of a tmament facility including the collection system, which is not a designed or established or operating mode for the facility. (2) "Severe property damage" mcans substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a by-pass. Severe property damage does not mean economic loss caused by delays in production. b. Bypass not exceeding limitations. The permittee may allow any bypass to occur which does not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to assure efficient operation: These bypasses are not subject to the provisions of Paragraphs c. and d. of this section. c. Notice (1) Anticipated bypass. If the permittee knows in advance of the need for 'a bypass, it shall submit prior notice, if possible at least ten days before the date of the bypass; including an evaluation of the andcipamd quality and affect of the bypass:. (2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as required in Pan II, E. 6. of this permit. (24 hour notice). d. Prohibidon of Bypass p) Bypass is prohibited and the Permit Issuing Authority may take enforcement action , against a permittee for bypass., unless, (A) Bypass was unavoidable to prevent loss of life, personal injury or severe property damage; (B) There were no feasible alternati�,es to the b}'pass, such as the use of auxiliary treatment facilities, retention of untreated wastes or maintenance during normal Part II Page 9 of 14 periods of equipment downtime. This condition is not satisfied if adequate backup equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment, downtime or preventive maintenance; and (C) The permitt.ee submitted notices as required under Paragraph c. of this section. (2) The Permit Issuing Authority may approve an anticipated bypass, after considering its adverse affects, if the Permit Issuing Authority determines that it will meet the three condidons listed above in Paragraph d. (1) of this section. 5. upsets - a. Definition. "Upset " means an exceptional incident in which there is unintentional and temporary noncompliance ° with technology based permit effluent limitations because of factors beyond the reasonable control of the permit=. An upset. does not include noncompliance. to the extent caused by operational error, improperly. designed treatment facilities,. inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation. b. Effect of an upset. An upset constitutes an affirmative defense to an action brought for noncompliance with such technology based permit effluent limitations if the requirements of paragraph c. of this condition are met. No determinationmadeduring administradve review of claims that noncompliance was caused by upset, and before an action for noncompliance, is final admirdstrad.ve action subject to judicial review.. Conditions necessary for a demonstration of upset. A permittee who wishes to establish the affirmadve defense of.upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that: (1) An upset occurred and that the permittee can identify the causes) of the upset; (2) The permirtee facility- was at the time being properly operated; and . (3) The permittee submitted notice of the upset as required in Pan II, E. 6. (b) (B) of this permit. (4) The permittee complied with any remedial measures required under Pan II, B: 2. of this permit. d. Burden of proof. In any enforcement.procee;iing the permirtee seeking to establish the occurrence of an upset has the burden of proof. NOMWORMT19=9(.,. Solids, sludges, filter backwash, or other pollutants removed in the course of treatment or control of wastewaters shall be unlized/disposed, of in accordance with NCGS 143-215.1 and in a manner such as to pr vent any pollut2nt from such materials from entering waters of the State or navigable waters of the United States. The permittee shall comply with all existing federal Pan 1I Page 10 of 1.4 regulations governing the disposal of sewage sludge. Upon promulgation of 40 CFR Pan 503, any permit issued by the Permit Issuing Authority for the t Uzadon/disposal of sludge may be reopened and, modified, or revoked and reissued, to incorporate applicable requirements at 40 CFR Part 503. The permittez shall comply with applicable 40 CFR Pan 503 Standards for the Use and Disposal. of Sewage Sludge (when promulgated) within the time provided in the regulation, even if the. permit is not modified to incorporate the requirement.

DESIGN REPORT Introduction Mountaire Farms Inc: (Mountaire) operates a poultry processing facility near Lumber Bridge in Robeson County; North Carolina. A location map is,provided as Exhibit III-1. The facility was acquired by Mountaire on March 1, 1996 from Piedmont Poultry' Processing Inc. The existing treatment system consists of a grease trap followed.by two :anaerobic lagoons and one facultative lagoon -and land application using slow rate spray irrigation systems. Currently there are seven '(7) spray fields covering a total of 152 acres of the 411 acre property. Seven day average flow from the plant is '0.56 MGD: Included in this flow are 10,000 GPD of sanitary flow. The sanitary flow is .treated in a,separate activated sludge wastewater treatment plant, is disinfected and .then combined with the processing wastewater. 'Construction of five (5) rapid infiltration basins began in October, 1997. These basins will be used to treat effluent from underdrains that exist in two (2) of the spray irrigation f elds, Fields C and. F. Spray irrigation and rapid infiltration is regulated ; under Permit No. WQ0000484 issued in October 1997. The rapid infiltration basins, when completed will eliminate two stream discharge points. The stream- discharge is regulated under NPDES Permit No. NC004185. A special order by consent, EMC SOC WQ 94-13 AdI, requires elimination of the point discharges on or before March 1, 1998. The facility presently operates one kill shift and a cleanup shift. Mountaire plans to double production at the plant by adding a second kill shift. The second shift will be added over approximately 12 to 18 months in four steps depending upon market conditions. This expansion of plant production will increase the flow of processing wastewater to, 1.11 MGD. As part of this expansion, Mountaire will improve and replace treatment elements of the existing system. New system components will include a dissolved air flotation system with nitrogen removal reactor, a new aerobic storage lagoon, r� t III-1 a new spray irrigation pumping station and additional land application areas. A process •flow diagram; is provided as Exhibit III-2.. 1Vlountaire is acquiring 280 acres, of land adjacent to the existing facility for expansion of spray, irrigation capabilities. The new . property `is currently being farmed.and consists of forested and cropped acreage. This . report provides details on the design criteria, descriptions and procedures for improvements to the wastewater. system including: 1. New mechanical treatment and treatment systems. 2. Wastewater characteristics. 3. Existing and new spray irrigation equipment: and pumping systems._ 4. Water balance and hydraulic loading. 5. Agronomic practices and nutrient' loading. . 6. 'Organic and salts loading. 7. Groundwater and subsurface characteristics of the site and groundwater monitoring plan. 8. Buffers and protection of water supplies. Asite evaluation, field survey. of soils, and agronomy report were prepared by licensed professionals. Detailed results -of these efforts are provided as separate reports and will be,referred to throughout this document. Treatment System Processing wastewater from the facility. is discharged from the offal room to' a grease trap that is frequently referred to as a' DAR This existing grease trap will be converted to a flow. 'equalization basin and used as a .wet well for the feed ' forward pumps that. will transmit the wastewater to the new treatment system. To convert the grease' trap, the mechanism will be removed, the center divider wall removed and a concrete fillet poured .in the bottom of the basin.. To prevent 'settlement , of suspended material, a submersible pump with a discharge header will be installed to -circulate and mix the contents of the basin. Three (3) Gorman Rupp Model T6A60B self -priming pumps will be installed .to III-2 pump the wastewater to the treatment system. Two, (2) pumpswill. will be' -on-line. and the''. third is a standby pump. Two -(2) eight inch diameter PVC SDR 26 force .mains will, extend from the feed forward "pumping station to the new treatment building., High and -low level alarms;- will be provided in the flow equalization basin.. An alarm " indication will also be. provided should a.pump fail to start. ,Initially, the, existing line from the grease trap to the anaerobic lagoon' will remain in service and in the event a high level occurs in the flow equalization basin, the wastewater will overflow to the existing first, anaerobic lagoon. A new treatment system will be constructed near Lagoon No. 3." The treatment system Will, consist of,a,.D'AF with a nitrogen removal system. The DAF selected does not use the traditional- chemicals, ferric chloride or acids used in a DAF. Typically ferric chloride; some. other chemical- or sulfuric acid is used to flocculate the pollutants. Polymer is then added ,and the -fats, .oils and greases coagulate .and float to the surface where they are removed- from the DAF.: Use of these chemicals 'may expose .workers .to safety hazards and can produce a float or sludge that is either difficult to render due to, the chemicals .or that must be land applied. The system selected by Mountaire is manufactured -by Sorin, Inc. The Sorin unit uses an.' electrical charge produced by magnets to. orient the molecular structure of the wastewater, and a polymer with an opposite charge, to produce the float material. - After the DAF, the Sorin system incorporates,a second magnet to, orient or condition organic contaminants. The, wastewater then enters an off -gassing chamber, 'a shallow serpentine .basin with diffused air, to further reduce the nitrogen and soluble„BOD. The discharge ,from the off - gassing uuit'then flows 'through a clarifier to remove any foam or scum that may have ' developed in'.' the off -gassing unit. A small portion of -the flow in the clarifier is recirculated back to the DAF for pressurization. Two (2) Sorin ,treatment units are being. provided, each capable of treating an average of . . 600,'GPM. Each unit is hydraulically able. -to handle 800 GPM (1.15 MGD). 'Each unit will, cycle - on and off in a- lead/lag fashion ' as the level in the flow equalization basin varies. The Sorin system is automatically controlled by a programmable logic controller ' (PLC). Alarms are displayed on the, control panel and an indication is transmitted to the office and- to an outside alarm light. The new treatment building will be constructed of concrete. masonry unitswith a precast concrete roof. In addition to the Sorin room, there will be separate rooms for chemicals, . blowers, the motor control center and an officeAaboratory. The office/laboratory will be constructed above the electrical and blower rooms: Windows will permit the operator to_ observe the Sorin treatment units, the aerated storage lagoon, the spray 'irrigation pumping station and a portion of the spray irrigation f elds. Drains and blowdowns associated with the Sorin'system, as well as floor drains in the treatment building,. are returned to a drain pumping station. The existing catch basin in the live -receiving area and a new catch basin located where the.float trailer will'be parked are also connected to this new pumping station. The discharge from the drain pumping , , station will be, pumped to the secondary screen in I the offal room where it will be screened, then.,flow back to'the new flow equalization tank, and be returned for additional treatment. Float from the new treatment' system will be removed from the DAF unit and conveyed . to trucks parked outside the treatment building. The same renderer who removes feathers and offal from the,facility will remove the float material: The float material will then be rendered. Discharge from the clarifier will enter a new 19.79 million gallon aerated storage lagoon: The lagoon sizing calculations are provided in the water -balance elsewhere in this document: The lagoon will,liave permanent storage of approximately 1,18 million gallons III-4 to act as ballast on the liner and permit operation of aerators. The resulting net storage volume is 18.61 million gallons. Four (4) 25 horsepower aerators will provide oxygen and mixing to prevent the lagoon contents from becoming septic. The lagoon will be constructed using.both on -site and off -site borrow materials. The . interior and exterior slope will both be 3 to ,1 and a 10 feet wide roadway will be provided around the top of the basin. The interior of the lagoon will be lined with a synthetic 30 mil liner. The liner will be XR5 as manufactured by the ' Seaman Corporation. A Request for Quotations wiIth detailed specifications for the earthworks and', liner is provided as Attachment A. Once the new aerated storage lagoon .is' completed the existing lagoons will no longer be used. The first lagoon will serve, as an emergency overflow lagoon for the flow equalization basin until final closure :of the lagoon'. The organic material in the three lagoons will be allowed to, naturally digest and after becoming stabilized the lagoons will, be'drained and -a final closure performed. During the stabilization phase; accumulated storm water will be spray irrigated to maintain.a low level in the lagoons. A new spray irrigation pumping station will be constructed on the berm of the new lagoon near the new treatment building. Five lines will be extended from a sump in the lagoon. Vertical pipes will serve as wet wells -for vertical turbine pumps. Initially, three pumps ' will be installed with up to five being utilized in the future. Condition III 5 of the existing spray°:'irrigation permit requires the grease trap to be cleaned quarterly. The grease trap is being converted to a flow equalization basin with mechanical mixing and therefore this condition should be deleted. III' 5 Wastewater Characteristics The wastewater characteristics discharged from the offal room at Mountaire Farms Inc. 's processing facility with the increased production are predicted to be as follows: Average Flow (processing day) 1.56 MGD Average Daily Flow (7-day average) 1.11 MGD pH 6.8-7.5 mg/l Biochemical Oxygen Demand 4000 mg/1 BOD Soluble 1000 mg/l Chemical Oxygen Demand 3500 mg/l Total Suspended Solids 2500 mg/l Oil & Grease 1200 mg/l Nitrogen, Ammonia NH3 20 mg/l Nitrogen, Nitrate NO3-H <.1 mg/l Nitrogen, Nitrite NO2 -H <.1 mg/1 Nitrogen, Total Kjeldahl, TKN 200 mg/l Total Phosphorus 25 mg/1 The Sorin system is a relatively new technology. For this reason extensive pilot testing has been performed to verify it's adaptability to treat wastewater at this facility. From the pilot testing, design parameters were established as follows: Design Value Pilot Test Results pH 6.5-8.0 units 7.2 units Biochemical Oxygen Demand 400 mg/l 263 mg/1 BOD Soluble 360 mg/1 187 mg/f Chemical Oxygen Demand 2000 mg/l 510 mg/l Total Suspended Solids 50 mg/1 17 mg/l Total Solids 950 mg/1 950 mgl/l Total Dissolved Solids 700 mg/1 700 mg/1 Oil & Grease 20 mg/l ' 15.7 mg/1 Nitrogen, Ammonia, NH3 20 mg/1 13.7 mg/l Nitrogen, Nitrate, NO3-N 0.1 mg/l <0.1 mg/1 Nitrogen, Nitrite, NO2 N 0.1 mg/1 <0.01 mg/1 Nitrogen, Total Kjeldahl, TKN 60 mg/l 59 mg/1 III-6 Specific Conductance 74 umhos Arsenic, Total (AS) 0.005 mg/l Boron, Total " <0.050 mg/l Cadmium, Total . <0.001 mg/l ..

Spray Fields The irrigation field layout is Sheets 3,4,7,8 `9 the current spray shown on and of .attached drawings. Existing fields comprise a total of 152 acres and consist of the following fields and acreage: Field A 8.252 Field B 6.750 Field ,C 35.033 Field F 26.527 Field G 47.489 Field H 14:193 Field I 13.587 Total 151.830. Fields G and H are equipped with center -pivot spray irrigation equipment. All other fields are equipped with solid set systems using PVC-underground.mains. and metal risers or aluminum • aboveground .pipes and risers. _� III-7 . The permit for" Fields H and I was issued on August 29, 1997. Equipment and pipe installation for. Field H was completed in -mid -October 1997 and Field I is expected to be completed by 'the end of November 1997. As part of the construction of ,Field I, , the southern pivot in Field G will be moved'approximately 85 feet south. This will permit operation of the two pivots in Field G without overlapping the spans. The possibility, of the; two spans, running into each other and damaging the equipment will be eliminated. On the existing 'property there are several areas which were previously spray. f elds but have become overgrown. These areas,could be converted to solid set spray, fields. They, include Fields B1, 7.722 acres; Field D,.3.499 acres., Field Eat 4.698 acres is anew field located adjacent to ' Field G' and the rapid infiltration basins. Their, small size - does - not. I reclude their inclusion in the spray irrigation program but their incorporation .is' not likely to -be a high priority. The new property purchased by Mountaire Farms Inc: totals about .280 acres north of the existing property on both.sides of S.R. 1704. Based on results of the site evaluation and. field surveys, new irrigation layouts were planned for the fields on the new property. Equipment in- these fields will include both center pivot and- solid set irrigation. Irrigation layouts are shown on .Sheets 3 through 6 of the drawings. Spray. Field J is 58.215 acres. The equipment will include a Valley Model 8000 center pivot'corner irrigation system. The main span is 640 feet long with a 268 foot corner arm and end gun. Flow rate is 1000 GPM at 50 psi. Field K is' 9.715 acres and will be equipped with a Valley Model 8000 298 feet long center pivot- with end gun.' Field L is . 24.189 acres and will be equipped also with a Valley Model 8000 527 feet long center pivot with end gun. Flow rates for Field K and L will be 280 -GPM and 720 GPM at 50 .. psi respectively. All center pivots use, 8 foot drop, spray heads and are equipped with, programmable controllers. Areas being sprayed on the new property that are not equipped with center pivot systems are referred to as Field M. All parts of Field M are solid get systems with PVC underground mains and risers. The use of solid'set systems allows Mountaire to make the best use of irregular shaped fields. •Acreage in Field M totals 29.375 a�es-- he total spray area available considering all existing and proposed spray fields i;�92 s 843' Gres. A' summary of the spray field areas is provided as Exhibit III-3. The. new. areas, Fields J, K; L and M, will be constructed as the facility expands its production: Field J and the existing fields are large enough to dispose of the wastewater from the first two steps of ` the expansion: Existing pumping -facilities consist of two 1;250 gpm vertical turbine' pumps. An underground force main delivers water to -individual fields. Typically, because of headloss in the existing piping, only one -pump is' used at a time. For the spray irrigation water distribution systems plans, see Sheets 5 through 10.. Anew spray irrigation pumping facility will be constructed in conjunction •with the new ` aerated storage lagoon. This pumping facility will distribute water to all•irrigation fields.. and will ultimately consists, of, five 1,000 GPM - .vertical turbine pumps located on the top of the aerated storage "lagoon berm with :intakes located at the base.. Depending upon the fields being used, all five pumps can be used to deliver 5,000. gpm or 7.2 MGD. Pumps will -discharge into -an 8 or 15 inch PVC force main that will 'tie'into -the existing supply lines and extend to; the new, property. The force main to the new property will terminate at. a. header system .located adjacent to Field L. ' Gates' valves located on the header will allow individual flow control to Fields J- K, L and M' This area adjacent to Field L will also serve as a central area -for the center pivot system controllers. 1II-9 Water Balance and Hydraulic Loading The, hydraulic loading recommendations. and water, balance are based on the soils, local climate, available storage, spray area, and wastewater. load. An analysis of existing site and a soil scientist's report, were prepared by Dennis J. Osborne, Ph.D., and are provided .as Attachments B and C. The wastewater system will be 1.11 MGD. The soils at this site are primarily loamy sands, are considered to be well drained, and will tolerate a high hydraulic loading. Soil borings indicates a seasonal high water table of 26 to 36 inches. There are no restrictive horizons. Vertical permeability, of the unsaturated subsoils is estimated to. be 0:2 to 6 inches per hour. The allowable drainage is calculated to be 7.17 inches per month. This is based on an irrigation cycle of 7 days which includes' 1/2.day of irrigation, 3.5 days drainage to field capacity and saturation, and 3 days of re -aeration time. This cycle will allow the soil to retain its natural permeability and maintain oxygen levels necessary for aerobic conditions. Using the drainage capacity, wastewater load. and local climatic conditions, a water balance was' created and is provided as Exhibit III-4. - The. water balance requires, a minimum of 205 acres and storage of 31.9 million gallons. Because Mountaire Farms has more land available for spray irrigation as detailed in the spray fields section; the water balance was recomputed using a spray irrigation area of 250 acres. The .revised water balance is provided as Exhibit III-5. With the increased acreage, the required storage volume is reduced to 7.746 million gallons.. As an -additional factor of safety, the storage lagoon was sized to store one additional week of flow, bringing the total storage volume to" 15.549 million gallons. To permit additional operational flexibility, the lagoon has been sized to store 1-8.61 million gallons and provides a total of 16+ days of storage. Mountaire will have, more' land under irrigation- than the minimum required by the water balance. The additional land will permit better management of the system. At certain III-10 times of the year, approximately 40 acres under irrigation that can be removed from use. ` This unused area can be rotated throughout the year providing necessary down time for equipment and field maintenance. The additional land will also reduce both the hydraulic and nutrient loadings. The water balance provides for irrigation of 78 inches per year or an average of 1.5 inches per week. Because of subsurface clay, irrigation rates should be limited to 0.75 inches per hour. Organic and Salts Loading Organic loading can become the limiting factor in spray application systems if hydraulic loading prevents oxygen diffusion into soil pores. Maintaining aerobic soil conditions insures proper decomposition rates, prevents odor problems and prevents soil sealing. Based on the total expected oxygen demand of the applied wastewater, the oxygen demand for waste decomposition can be calculated and compared to the available oxygen based on soil porosity. For the wastewater expected at Mountaire, oxygen demand applied is approximately 44,000 pounds per week, while the assimilation rate of soils, based on hydraulic loading described earlier, is 1,800 pounds per acre per week. Therefore, only 25 acres are required to meet the organic loading requirements. Since up to 290 acres are available for irrigation organic loads will not be a limiting factor. Highly saline wastes affect slow rate irrigation systems in one of two ways. First, high salt concentrations can effect osmosis and thus plant water uptake. Second, specific ion toxicity can result if sodium is highly concentrated as compared to other ions. The sodium adsorption ratio for typical Mountaire wastewater is 10 which is in the acceptable range for land application. The specific conductance, less than 250 umhos/cm is typical of water with low salinity. In addition, coastal 'bermuda grass is salt tolerant. These factors indicate that salinity will not be a problem at the Mountaire site. Agronomy Report/Nutrient Management Spray irrigation systems rely on a crop to assimilate the applied nutrients. The agronomy ,. report in Attachment D suggests' that the coastal bermuda grass/rye grass combination should do well at the , Mountaire site: : The --agronomy report, • describes practices that Mountaire will follow to -insure success. . A .brief summary of the cropping system. follows: Fertilization Nitrogen will be', provided by wastewater application. The nutrients potassium (K) and phosphorus (P) will also be available in the wastewater although they, may need to be added. An N-P-K ratio of 4-1-3 should be maintained. This is equivalent to P and K levels of 88 pounds per. acre and- 262 pounds per, acre respectively. A soil test done at the beginning at the growing season will indicate the levels of P and K present.. If necessary, Mountaire will add P at the beginning of the growing season and apply one- half of the K at the beginning of, the growing season. and. the second half at mid year., f - ` Typically, soil test reports, will make recommendations based on the crop being grown. Lime will beadded,, as necessary and appropriate, before the. growing season to maintain a, soil pH between 5:8 and 6.5. Again,' soil tests will be performed. to determine if lime is: necessary. Harvest Management =. The first cutting will be done when plants reach 15 inches and then every 4 to 6 weeks. A 3 to 4 inch .growth will be left for over wintering, and will not be removed until at least mid February.. A -burn will be conducted 3 to, 4 weeks' before the dormancy period is ended. Rye Grass Overseeding Rye grass 'will be overseeded to assimilate nitrogen during the coastal bermuda grass dormant period.,, A.soif test.may be -done to determine additional fertilizer requirements for the Rye grass.' 'Rye grass should be overseeded in the fall and . cut and baled in the: spring before burning takes place. •III-12 Nitrate Toxicity -. If hay is to be sold, it will be tested. for nitrate concentration. High - nitrate .concentration can be toxic to animals. Feeding high levels of nitrates can result in,reduced feed,consumptio. lowered production, abortions or death. A forage guide is attached to the agronomy report that discusses nitrates in detail. The plant available nitrogen (PAN) applied cannot exceed the amounts which can be used" by the crop. The Bermuda/Rye Grass combination being used at the Mountaire site can assimilate 350 lbs/acre/year or more,,which is adequate for the wastewater being applied. This is demonstrated in the following, calculations: N.C. DENHR Plant Available Nitrogen Calculation: PAN = .0.2 (TKN-NH3)+0.5(NH3)+NO2+NO3 Assuming the, following wastewater characteristics: Flow = 1.11 MGD TKN = 60 mg/1 NH3 = 20 mg/1 NO3 = 1 mg/1 { NO2 = ,1 mg/1 The PAN Concentration = 20 mg/1 or 166.8 lbs/mgal Based on..a Flow of 1.1 MGD PAN Loading is 185.1 lbs/day or 67,562 lbs/yr Using the Bermuda/Rye grass cropping system 350.1b/ac/yr can be assimilated.. 67,561 lbs/yr = 193 acres required 350 lb/ac/yr The acreage required to assimilate the applied PAN at an assimilation rate of 350 lbs/acre/year is' 193 acres. Therefore, 'if the recommended agronomy procedures are III713 followed, the nitrogen loading can be assimilated on the 290 acres of proposed spray fields. Groundwater For the design of the rapid infiltration basin, a study of the geology of the area was performed by G.N. Richardson and Associates of Raleigh, North Carolina. The North Carolina Geologic Map indicates that this site is underlain by the cretaceous age Black Creek formation, described as gray to black marine clay with thick lenses of cross -bedded sand. Aquifer slug testing performed on monitoring wells and piezometers placed throughout the site indicate that hydraulic conductivity is from 0.18 feet per day to 21.18 feet per day. The average across the site is 7.0 feet per day. Based on these same slug tests transmissivity is estimated to be 350 sq. ft. per day. Groundwater quality will be monitored with a well network around all spray fields. Sheet 4 of the drawings shows the location of existing and proposed monitoring wells. There will be eight new wells that are both upgradient and downgradient of the new spray fields. Six will be located on the new property and two will be on the existing site. One existing well, MW 23 will be abandoned due to the relocation of Pivot G. Based on elevation data derived from measurements from existing monitoring wells, groundwater flow is generally toward the southeast, flowing to the Great Marsh Swamp. See Exhibit III-6. The spray irrigation permit requires the monitoring wells to be sampled every April, August, and December for the parameters listed below. New wells will be sampled at the same frequency for the same parameters. 1. Ammonia Nitrogen 2. Chloride III-14 3. Nitrates S 4. pH 5. TDS 6. TOC 7. Fecal Coliform 8. Volatile Organic Compounds 9. Water Level Water levels are recorded before collecting the sample for the above parameters. Water Supply Wells and Buffers There are no domestic water wells within 100 feet of existing or proposed spray fields. With the exception of the existing permitted fields, the following buffer areas will be maintained: 1. 400 feet between wetted area and any residence or places of public assembly under separate ownership. 2. 150 feet between wetted area and property lines. 3. 100 feet between wetted area and wells. 4. 100 feet between wetted area and drainageways or surface water bodies. 5. 50 feet between wetted area and public right of ways. 6. 100 feet between wastewater treatment units and wells, and 7. 50 feet between wastewater treatment units and property lines.

RICHARDSON & ASSOCIATES Engineering • Geologidail October 31, 1997 Mr. Bob Kerr, P.E. CABE Associates 144 S. Governor's Avenue P.O. Box 877 Dover, Delaware 19903-0877 RE: Site Investigation Report Mountaire Farms of North Carolina, Inc. Lumber Bridge, North Carolina Dear Bob: G.N. Richardson & Associates (GNRA) is pleased to present this report of a site investigation performed at the referenced site. The site was visited on October 9, 1997, during which time eight hand auger borings were performed in and around the footprint of the proposed aeration lagoon. The borings were fitted with temporary standpipe piezometers, to allow long-term observation of ground water levels. The piezometers were revisited on October 23, 1997 to measure ground water levels. Preliminary subsurface information was conveyed to you during the site visit, followed by a summary letter dated October 13, 1997. This report presents the findings of the investigation and recommendations, for design and construction of the new wastewater basin. Based on subsequent ground water observation, the recommendations presented in this report remain substantially the same as discussed previously. Site and Project Description Figure 1 presents an aerial photograph of the plant site, including the location of the new waste water lagoon and hand auger boring locations. The proposed lagoon will be a lined 19.8 MG aerated waste water storage lagoon; located about 250 feet north and west of the plant building, and about 100 feet east of the existing lagoons. The'footprint of the new lagoon covers approximately 6.8 acres, excluding the exterior berm slopes. The site is relatively level, with ground surfaces varying from El. 197 at the east side of the lagoon to El. 195 near the south east corner of the lagoon. The ground is vegetated with -grass, scattered scrub trees and underbrush. Evidently, the site was previously used for agriculture, as portions of the footprint have been plowed in the last few years. A tentative site development plan provided by CABE Associates shows proposed bottom elevations of El. 190 to 195, sloping to the west. A sump is being planned for the southwest corner of the lagoon, which may extend to El. 185, rising within a few feet laterally to El. 190. The perimeter berm will be set at El. 206.5, with interior and exterior slope ratios of 3H:1V. A pretreatment building will be set outside the lagoon; with a finished floor at El. 200. This 417 N. BOYLAN AVENUE - RALEIGH, NORTH CAROLINA 27603 TEL. 919-828-0577 - FAX. 919-828-3899 structure is planned to have 19-foot high masonry walls and a precast concrete roof. The floor is assumed to be a monolithic concrete raft, with a maximum anticipated bearing pressure of 3000 psf. The pumping station will be supported on a new 5-foot high compacted soil structural pad. Subsurface Conditions Tables 1 and 2 present a summary of ground water level observations and soils encountered at the hand auger boring locations, respectively. ,Figure 2 presents a generalized subsurface profile, based on the hand auger boring data. The borings were extended to depths of 5 to 8 feet below existing ground surfaces. All of the borings terminated in saturated soils, either within the water table (saturated zone with positive pore pressures, capable of producing a phreatic surface) or in the `capillary fringe' existing above the unconfined aquifer (saturated zone with negative pore pressures, no phreatic surface). Color and texture changes of the recovered soil samples were noted to determine the likely position of the seasonal high water table (discussed below). Generally, the soils consists of relatively `clean' to slightly silty and clayey fine to medium sand. Representative Unified Soil Classification System (USCS) designations of SW, SM and SC are typical. The' SW and SM soils exhibit relatively low cohesion, but these soils appear to inter - finger with the more cohesive SC soil types. The upper 24 to 30 inches generally consists of slightly moist SW soils, while the percentage of fines and moisture content increases noticeably below these depths. Distinct tan and orange mottling was noted below depths of 36 to 48 inches. The soils observed in hand auger borings B-1 through B-5 appear similar to those encountered in earlier test borings that extended to depths of 15 to 40 feet, performed in another area of the site. The earlier borings did not exhibit any distinct horizons of soft clay or unsuitable foundation soils. Based on this visual comparison, it appears that the soils at the hand auger locations will provide sufficient foundation support for the lagoon berm and pretreatment building. A majority of the soils encountered in the hand auger borings exhibit a generally low -organic content (vegetative material), and there was little topsoil. A exception occurs within the eastern side of the footprint, where dark brown soils (iron and manganese oxide stained), laden with organic debris, were encountered from depths of 20 to 48 inches (B-6) and from 12 to 18 inches (B-7), and 15 to 28 inches (B-8). The dark brown soils are underlain by light to dark gray silty and clayey sand at B-6 and B-7, and the dark soils are underlain by tan -orange sandy soils below a depth of 36 inches at 8-8. Nothing was noticeably different at the surface at these locations. The pattern of the dark brown is believed to represent a relic small creek channel, or perhaps a small `bay' has been in filled. The extent of the organic debris -laden soils, which are unsuitable for compacted embankment construction, is unknown. However, these soils appear to be present in relatively limited quantities, at locations where the average grade cut is shallow (less than 24 inches). These soils could have application as topsoil for the exterior slopes of the perimeter berm. It does not appear that large quantities of the organic soils will be encountered within the west side of the lagoon, where the deeper grade cuts are now planned. CABE Associates - Mountaire Farms of NC October 1997 Wastewater Lagoon Site Investigation Report . Page 2 Ground Water Trends Ground water level data is presented on Table 2. The ground water levels observed at the time of - completion (10/9/97) and stabilized water levels several days later (10/23/97) are similar. At most of the piezometers, water levels had decreased slightly from the time of completion, except at B-6, which increased about 7 inches. Please note that the water levels at the piezometers are very near the bottoms; and there is a f2 inch deep end cap at the bottom of each piezometer which can trap water. It appears that the end caps may be producing the `water levels' currently observed at several piezometer locations. Two piezometers (B-2 and B-7) have remained dry. Each of the hand augers borings terminated in saturated soils, but it appears that the water encountered during the installation of the piezometers may reflect a `capillary fringe' near the top of the water table. It should be noted that the last few months were drier than normal, and water levels may be unusually deep at this time. Mottling of yellow and orange pigments, caused by migration of iron oxides in the soils, indicates a variable ground water position that is often due to seasonal fluctuation. The mottling observed in the soil samples at depths generally varying - from 3 to 6 feet (above the zone of saturation) suggests that water levels may rise higher at other times, or that water levels have been higher in the past. The timing of the past ground water movements, e.g. whether it occurred within the past few months or many'years ago, cannot be readily determined based on the available data. However, the presence of `gleying', a pigmentation caused by the reduction of iron compounds in the soils that results in a consistent grey or green -blue chroma. This typically indicates permanent ground water saturation associated with the mean ground water position. Table 2 only indicates gleying below a depth of 5 to 6 feet at B-3. The other hand auger borings terminated in mottled soils, suggesting that the borings ended above the permanent water table. This is supported by the piezometer data. It cannot be discounted that spray irrigation activities nearby could affect water levels at the lagoon site. This is more likely to occur on the east side of the lagoon, closer to the spray field. Recommendations The following recommendations are made based on the available data, our understanding of the project and past experience with similar projects and subsurface conditions. If plans are altered significantly from those now under consideration, these recommendations should be reviewed and, perhaps, augmented or amended to reflect changed conditions. If unanticipated subsurface conditions are encountered during construction, GNRA would appreciate an opportunity to observe those conditions for review and comment. Site Grading and Excavation Considerations Initial site grading activities should consist of clearing and grubbing, to clear the footprint of loose topsoil, vegetative matter, excessively wet or clayey soils or soils deemed unsuitable by the project engineer. These soils should be stockpiled on the site and used for dressing the exterior side slopes of the perimeter berm. During general excavation for the lagoon, it is likely that soils CABE Associates - Mountaire Farms of NC October 1997 Wastewater Lagoon Site Investigation Report _ Page 3 that are unsuitable for embankment construction will be encountered. These soils should be removed to the stockpile, as well.' The acceptance of soils from the excavation that are suitable for embankment construction should be made by a qualified engineer or soils technician working l under the supervision of an engineer. Areas intended for construction of compacted embankments should be densified in place with suitable compaction equipment prior to constructing the embankment. A vibratory roller of sufficient weight to improve the density of soils at a depth of 3 to 5 feet below existing ground surfaces is recommended. Following densification, the embankment areas should be proof -rolled in the presence of a qualified engineer or soils technician, with a fully loaded dump truck or similar piece of heavy, rubber -tire equipment. Any area which fails to stabilize should be reworked and recompacted, then proof -rolled again. If an area still is unstable after reworking, the soils in that area should be undercut and replaced with suitable compacted fill. All embankment construction for perimeter berms and structural support should be placed and compacted in accordance with standard engineering practice. Soil selection for embankments should be made such as to avoid overly wet, sticky or non -cohesive soils, or soils containing more than .10 prevent organic content. All soils should be placed in relatively thin, horizontal lifts, not exceeding 18 inches uncompacted lift thickness, and compacted to a minimum of 95 percent of the standard Proctor maximum dry density established for that soil type by a geotechnical engineering laboratory. If variable soils are encountered in the excavation or supplemental borrow.sites, additional laboratory testing may. be required. All soil placement and compaction should be inspected by an experienced technician, working under the supervision of a soils engineer. A regular testing schedule and construction quality assurance (CQA) procedures should be incorporated into the project specifications. If the project is put out for bid to a general contractor, the bid documents should contain provisions to assure quality workmanship, e.g. contractor shall be responsible for meeting specified soil density and keeping'a record of CQA testing. Alternatively, the project could be separated into several contracts, administered by CABE, a designated representative, or the Client, in which case one of the contracts should include a soils laboratory to provide onsite guidance and testing. Ground Water Control Based on Figure 2, the proposed grade cut will extend within a couple feet of the measured water levels over a large portion of the lagoon footprint. Excavations for the deeper portions of the lagoon, including the sump, will undoubtedly extend below the observed water table. Ground water levels could rise to' higher levels than currently seen due to seasonal and climatic changes. The excavations may experience instability due to ground water seepage, possibly resulting in bottom heaving or side slope raveling. Should the excavations become unstable, it may be necessary to stabilize the bottom and the lower portions of the side slopes with crushed stone. To minimize instability, consideration should be given to implementing temporary ground water controls, e.g. a system of ditches inside the footprint, or trenches and/or well points outside the footprint, to lower water elevations prior to construction of the sump or installation of the liner. CABE Associates - Mountaire Farms of NC October 1997 Wastewater Lagoon Site Investigation Report - Page 4 To stabilize the sump area, a relatively economical solution is to dig one or more trenches in proximity of the sump and pump the excavations with one or more gasoline -powered creek pumps. If the deeper excavation encounters ground water that does not respond satisfactorily to trench pumping, perimeter well points can be considered, although this option is costly and not recommended as a first initiative. Depending on ground water conditions at the time of construction, shoring and bracing or additional side wall lay back may be required to prevent collapse of open excavations. Protective measures should be taken for manned entry into any excavation extending deeper than 5 feet below existing ground surfaces, or into the water table, per applicable'OSHA regulations. The soft conditions likely to be encountered may make support of earth moving equipment difficult. Again, the current data show that the water table is near or slightly below the planned lagoon bottom, and it is uncertain based on current data whether future ground water levels will rise significantly above present levels. There is a possibility that the lagoon liner could be placed at risk due to hydrostatic uplift, in the event of a complete draw down of the lagoon. Such could conceivably occur due to future maintenance or repair requirements. Consideration should be given to fitting the lagoon liner with an underdrain system. Due to the relatively flat topography, a gravity drain system of permanently lowering the water table does not appear feasible. One possible option is to fit the under drain with its own sump and pumping system. Lagoon Liner Considerations The lagoon will be lined with a UV resistant synthetic liner. The liner may be fitted with a surface drain layer to facilitate gas removal from the lagoon. We recommend that the liner be installed by an experienced installer, with a minimum of one million square feet of installed liner to his credit. Care should be taken to follow manufacturer's recommendations for storage and handling of the materials. A CQA program should be implemented to assure that seams meet project specifications and that proper perimeter anchorage is achieved. The liner should be designed to withstand stresses associated with seasonal temperature changes and possible settlement. A settlement analysis has not been performed, but it is conceivable that settlements could be experienced. At,full pool, the hydrostatic stresses acting on the lagoon bottom (and underlying soils) will be an estimated 1200 psf in the deepest portion of the lagoon. The reduction overburden stress associated with the excavation of soils from the center of the lagoon should roughly balance the anticipated hydrostatic stress at full pool. Thus settlements beneath the lagoon are expected to be negligible, but unforseen localized settlements could occur due to undetected soft soils beneath the lagoon footprint. Foundation Support Considerations The subsurface soils appear favorable for support of relatively light structures, such as the pump station (maximum anticipated foundation loads of 3000 psf). It will be necessary to densify the foundation soils prior to placing the compacted soil embankment, and embankment compaction criteria should be observed, to minimize the likelihood of post construction settlements. We CABE Associates - Mountaire Farms of NC October 1997 Wastewater Lagoon Site Investigation Report Page 5 understand that the foundation design may include a monolithic raft design, essentially a thick reinforced concrete slab, typically 24 in thickness. If a raft foundation is selected, it should be designed for a maximum subgrade modulus value of 100 pci (pounds per cubic inch), unless addition soil testing is performed. Alternatively, a separate ribbon wall footing'and floating floor slab may be considered. The footings should be embedded a minimum of 18 inches and made at least 16 inches wide and 8 inches thick, with tied steel reinforcement. The floor slab can be designed for the same subgrade modulus value. In the past, foundations so designed are relatively economical and perform satisfactorily given the assumed loading range. However, the mechanical loads associated with machinery vibrations will likely require thickened foundations. All prepared foundations should be inspected by a qualified engineer prior to pouring the concrete footings. A detailed settlement evaluation has not been performed, nor have laboratory consolidation tests been performed. A majority of the subsurface is relatively sandy, which would make sampling for laboratory testing difficult. Given the complexity and cost of obtaining field settlement data, - e.g. via an instrumented test fill, the relatively slight chance of damaging settlements for a building of this size and foundation load does not justify a field settlement test. A properly designed and constructed structural foundation with the assumed loads should not experience excessive settlement, providing that the recommended subgrade repairs are performed and good construction practice is observed. As a precaution, the structural area can be surcharged equivalent to the anticipated foundation loads and leaving it there for at least 30 days. This could be accomplished by placing compacted embankment to a 30-foot thickness (assumed, compacted unit weight of 100 pcf), then removing the excess soil and shaping the pad to the desired grades. The excess soil can be used ,elsewhere to construct the perimeter berm. Sucharging structural foundations is a common practice in with settlement sensitive structures. However, it may prove more economical to design the pump building with a `raft' type foundation, to reduce its sensitivity to settlement. Closing We appreciate the opportunity to work with you.

C,: Loading Rate Evaluation J _ `- 1. Hydraulic Loading Several factors' must be considered in evaluating the adequacy of the.hydraulic'loading design of any -soil -plant system.' These ,factors are listed as follows: A) Application Rate B) Application Volume C) Application Interval D) Seasonal Variability. (A) The application rate or the instantaneous rate of water applied during,irrigation; usually expressed as inches per hour, is a critical. factor 'in the day-to-day operation of a successful land.treatment .system. This rate must not exceed the soil's capacity to accePt water without'runoff or ponding for' -more than .a few hours. For preliminary design purposes, Table 1 is A-4 w" often used to indicate, typical infiltration rates for various soil textures and slope conditions. These rates have been estimated by experienced soil scientists and irrigation engineers from soil texture and soil porosity evaluations in the field in conjunction with slope and vegetative conditions.

For }toor _�' surface soli condl tuns, rates may I)e as much as 50V leas. A-5 The soil. variables considered on this site all fall within Class II of Table 1 and indicate that ''the site should tolerate average application rates up to 1.5 in./hr. throughout the field areas. Other factors to be considered in hydraulic loading include irrigation volumes and intervals between irrigations plus seasonal variability of application. The seasonal variability is based on the assumption that the soil is well drained or modified to act as a well drained soil through artificial drainage. Anything less will result in periods of the year when the soil profile is almost entirely saturated with rainfall and cannot accept any additional load. These periods of time are reflected in the, drainage classification shown as follows: Drainage Estimated Periods of Class Soil Saturation Well Drained Extremely Short Periods Moderately.Well Drained 0.5 - 1-1/2'Months/Yr. Somewhat Poorly Drained 2-3 Months/Yr. Poorly Drained 4-5 Months/Yr. Very Poorly Drained > 5 Months/Yr. All areas within the sprayfield should act as if they were well drained soils. The factors of hydraulic loading determining irrigation volumes and intervals or resting time between irrigation are determined by soil, vegetation, and climatic condition at the site. A-6 These factors were considered together in developing a water budget, for the site using, the'standard equation: Precipitation + Irrigation < Soil -Drainage + ET.+ Runoff This approach was outlined in North Carolina Water Resources Research Institute Report -118, by Carlile and Phillips and has been used with excellent success in evaluation and design of various ,..wastewater irrigation systems throughout ,the Southeast. The precipitation and evapotranspiration can be obtained from records., but the soil drainage must be estimated or calculated. In determining the drainage rate, -an estimate or measurement is made as to the maximum amount of water that could be applied to the soil to completely saturate the topsoil.. After saturation, the soil is 1 allowed.to drain until the drainage rate becomes small. Drainage 'from saturation to field capacity may take a day or less for sandy soil or many days for finer textured soils. Figure 1 indicates' the relative volumes and drainage times for various soils. In the Mountaire Farms case, drainage' is controlled by a hydraulic gradient on'th'e'gently sloping -to nearly level site.. Although soils'are rapidly permeable, wastewater cannot.drain as fast as it can' leave the .surface..horizons.' This, is taken` into account by constructing a water balance for'subsurface,horizons. As a general case subsurface horizons direct the redistribution-, of applied water; surface horizons' direct infiltration of applied. water., Many spray irrigation systems 'have been hydraulically overloaded because hydraulic loading rates were determined for surface I horizons ° alone: Only if the surface and subsurface horizons are the same texture' might this be acceptable. TIME —DAYS Figure 1.. Drainage. rates and volumes for -various soil materials. A-7 After field capacity is reached, generally at least another 3 days should be allowed for the soil to re -aerate. Thus, the total cycle will be composed of: Irrigation'Time,+ Drainage Time + Re -aeration Time The amount of water drained per cycle will.be the amount of water lost from saturation to field capacity, i.e.: H20/cycle = H2O @ saturation - H2O @ FC The monthly drainage rate can then be determined as: 365 days/12 mo. X H2O/cycle = H2O drained/month .days/cycle In B-horizons the average amount .of water held between saturation and field capacity in soils such as these has been reported as 23.5% by,,volume. Thus, if one-half of A -horizon thickness is saturated and allowed to drain to FC, the following amount of water could drain: 7" X 0.235 = 1.65 inches of water This will also be the drainage per cycle. Figure 1 indicates that these A and B-horizons will drain to FC-in about 3.5 days. Thus, drainage can now be determined as: Irrigation Time 0.5 Days Drainage Time 3.5 Days Re-aeration"Time 3.0 Days Total Cycle Time .7.0 Days The monthly drainage rate would be: 365 days/12 mo. x 1.65 in./cycle = 7.17 inches/month J 7.0 days/cycle A-8 The other method of estimating drainage rate is that suggested by'. EPA in its "Process Design Manual for Land 'Treatment. of Municipal Wastewater".(EPA))-625/1-77.-008, 1981)'. By this method, drainage rates "'are estimated at 4% to 10%'of soil permeability of the most limiting layer. Using the minimum reported values of soil permeability for -the limiting layer of these soils (0.6 in./hr.), the minimum drainage rates can be estimated as: 0:6 . in'. /hr. x '24 hr. /day x 365',days/12 ' mo. x 4%: = 17.52 in. /mo." As can be seen'; the North Carolina method is more conservative than the EPA method, particularly when the EPA method is -calculated using. the 4% level. Using the value of 7.17 inches/cycle for,soil drainage,, a Mean F1ow,WAter Budget Analysis ,can now be calculated (Table 2). The potential evapotranspiration ( PET) .was taken from Hardy ',.s ":Weather and Climate in -.North Carolina". Precipitation data was taken from the"Weather and Climate in North Carolina" by Epperson, et.al. , citing Red Springs, North Carolina data. Using the PET and the estimated drainage rate, the total loss of,water from the soil -can be.calculated,(.Column 3). .Subtracting the precipitation from -'this loss gives the allowable irrigation (Column 5). (Note: allowable irrigation can never -be negative.). The mean monthly irrigation rate is then calculated and used to determine wetted area requirement. Since. in some months the allowable irrigation, rate will .be less than.the design rate some storage capacity must be provided.. This capacity is -calculated by subtracting the allowable irrigation (Column. 5) from the mean rate and getting a monthly storage A 9.. requirement These monthly requirements. are then' accumulated. to. determine'the maximum storage -quirem'ent";during the ge requirement' year (Column, _-7). The,, volume, -of. storage is then determined by multiplying the maximum value in the cumulativi e storage column by the,'aiea 'requirement for the i' rrigatibn field. Since.'--limi ; te d field data are a ila b le, on ','thi site, ..considerations basedone.x eridnc'e, with imilar sites were also used. These considerations, should be examined more closely because of'the,following: A. -Drainage Rat' -Drainage Time The :time, required for, .a soiltodrain from saturation ,to field capacity was measured on soil cores collected as part of a research project in the Soil Science. ID epartment, North Carolina Stat'e,'Universiiyo'''Data'wer6 collected in the laboratbryf not the The data haVe,been,wid6ly accep'ted'as valid and'standard, however. B)' Sustained Drainage In calcuilating.the drainage rate it is -assumed that this drainage', rate,, can be, sustained even after, the site begins '' to receive the additional irrigation load; C) Re -aeration Time The monthly, ',drainage' rate is'- a function of the re- aeratilbn time,.. required,, to satisfy the'., organic -loading rate. Consequently, the organic rate and the hydraulic loading rate must be.,de.veloped,ih parallel. A-10 2,. Weather Data' The average.values of PET were,.used because PET.does not vary as markedly as precipitation",f.rom year to year.' However, it is a bit more difficultto select a design year for precipitation values. The wettest year in'20 years (or some -other time period) ,will give a conservative estimate of monthly irrigation rate but.it,. will not assure that the storage`requirement is adequate,. This is because the volume -,of -'storage required will depend on both total precipitation and distribution of the precipitation. Table 2 was calculated using data for the long term -average., Date in, Table, 2 shows that irrigation amounts could range from 4.50 to 7.85 acre inches per acre per month on these 'soils with a mean value 'of 6•.07 in. /mo. At a design. flow of 1,114, 000, GPD and r' a 7 day week, the required acreage would.be: 1,114,000,g/d X 365.days/12 mo.. 205.59 acres 27,152:4 gal./ac.. in: 6.07 in./mo. This would be the minimum.land requirement if maximum storage of the wastewater was provided. Maximum storage .can -be, calculated from Column 7 of Table.2 as: 5.77 in. X 205.59 ac. = 1186.3 ac. in. = 98.85 ac-ft This represents about'a 29.day storage requirement for -the liquid wastewater if the minimum land area of 205.59 acres 'was used for the irrigation. The volume can be reduced by increasing,the land area used for irrigation, or by more exact area -to volume matching. A-11 3. Organic Loading When wastes are applied to the soll, it is important that the soil environment remain aerobic to 1) permit rapid decomposition and stabilization of the wastes; 2) prevent the development of objectionable odors; and 3) prevent partial sealing of the soil that occurs under anaerobic conditions. To maintain these aerobic. conditions,, the oxygen utilized by the diffusion of oxygen from the air above the soil into the soil pores. Since oxygen diffuses much faster through air than through water (about 10,000 times faster) it is obvious that diffusion of oxygen into a soil will depend on the water content of the soil. As a soil dries out, more . and more of the 'soil pores are filled r with air and consequently, oxygen diffusion, into the soil increases. North Carolina Water Resources Research Institute Report 118 by Carlile and Phillips describes equations that have been developed to estimate the diffusion rate of oxygen into soils. By substituting appropriate values in the equations one can develop the following expressions: M = 1556 where M = pounds of 02 diffusing into one acre of soil per day S = fraction of the soil volume filled with air (air filled porosity) We already know from the previous section that the soils on the site lose water equal to an average of 23.-5% of their volume r J when draining from saturation to field capacity. Thus, S at field capacity is .235 and the corresponding oxygen diffusion rate is: A-12 M = 1556 1 0235 M 754.29 lb. 02/ac./day Studies have shown -that' about 120 - 150 ib 02/ac.day are required to meet the needs of plant roots and soil microorganisms under normal conditions, Thus,, approximately 604:,,,lbs. 02/ac,./day is available to -meet the oxygen demand of the, applied wastes. From the hydraulic loading cycle,.one can calculate the amount of oxygen that,,can diffuse into,:the soil.during the cycle. Using the conservative approach that 02 transfers only take place during the 3,days of re -aeration, then this allows 02 per cycle to be calculated as: 3 days X 60.4 lb. 02/d ='1812 lb. 02/cycle/ac. ,Since each hydraulic cycle -.is proposed as 7.0 days-, the allowable 1 TOD loadings would be: 7 days/wk.

TOD/wk./ac ;Under proper management and soil -conditions, organic loading at these concentrations and loadings should not be .a limiting factor. Nutrient Loadings Nitrogen Loading Rate. A suitable N.loading rate can'only be determined with some prior knowledge of the availability of the,N in the. wastewater. The organic .nitrogen in wastes is not', immediately available for crop -uptake but becomes somewhat -slowly available. -as soil microorganisms decompose the wastes... Total 'of' all nitrogen sources on Page 2 shown nitrogen content-to'be less than 0.05 percent. - Agood soil testing program. .is always necessary to % substantiate the availability of nutrients as assumed here and to make adjustments if they are not adequate. However, it does appear that the present. calculated wastewater applications will not supply All needed nutrients for' -any -crops. Salt Loadings The effect of salts .on soil -plant systems are dependent' on the chemical characteristics of. the applied water; the physical,. chemical and mineral properties,of the soil; and the salt tolerance ,or physiological characteristics -of the growing plant. A-14 When considering chemical properties of a potential„irrigation• water, twoprincipal factors .are bf.concern for application to a- soil -plant system:. A) The salinity or ,total .salt 'content of 'the water. B) The'ratio of sodium to other cations in solution. Salinity may ,effect plants by' 1), osmotic pressure, .2) ionic interference, and 3) toxicity.of chemical species. High salt water or wastewater applied to land will raise the osmotic -pressure of the' ,soil' solution and lower the gradient: in osmotic, potential between soil solution and root. cells. The net -result is less water uptakeby the -,plan at equivalent soil moisture contents. The visible -effects 'are reductions' in; both' growth. rate and total plant size with subsequent reduction in both quality, and yield. Salt affected -plants do not respond to applied_ fertilizers which further, adds ;to the osmotic potential of the soil solution.' and thus aggravates the.salinity effects.

Methods Dennis J. Osborne, Ph.D., Licensed Professional Soil Scientist, conducted a soil survey and site evaluation of the tract during August 12-13, 1997. In general the work entailed a detailed review of the site to accomplish three objectives: (1), Evaluate soil conditions, (2) Determine if the soil conditions were acceptable for permitting for spray irrigation waste systems, and (3) Present.resdlts of such an investigation so the results could be used as part of a Permit Application if such an application.were needed. On -foot transects and traverses were performed to cover all the proposed sprayfield areas. Along these transects and traverses B-2 On -foot transects and traverses were performed to.cover.all the proposed sprayfield,areas. Along these transects and traverses hand auger borings were advanced to examine soil properties and field -classify the soils. Field classification. was accomplished by comparing field descriptions with the range of characteristics of typifying pedons of each Soil Series as given in'the'USDA-SCS "Soil Survey of Robeson County, NC" and as given in standard Series Descriptions. These data were collated into the Soil Series Descriptions attached'as part of this report. A topographic map at a scale of 1:2000 entitled "Location Map" by CABE Associates, Inc. was used for on -site location of general areas to be evaluated (FIGURE 1). Further, the'soil survey was superimposed on a property map' to enable examination of field - determined soil boundaries. (FIGURES 2a and 2b). The- relevant portions of Map Sheets 2 and 5 of the USDA Soil Survey of Robeson County,. NC are included as FIGURES 3a and.'3b to offer a photobase. Soils were examined in shallow pits and from hand samples removed from corings 'made as hand auger samples were advanced. Properties were 'noted and combined to produce Soil -Series Descriptions. Descriptions, attached to this report are to be considered modal or typical for the .tract. Properties noted to classify soils to Series Level of Soil Taxonomy ,were depth to seasonal high water table, estimated CEC; pH, soil color, 'texture, structure and consistence, horizon development, slope,, and soil depth. Soils were found generally as shown on Figures 2a and 2b. These maps are portions of a complete site map prepared by CABE. B-3 Findings - Site The 4 (four) areas evaluated are parts of a much larger parcel owned Mountaire Farms Inc. near Lumber Bridge N.C.. The areas evaluated comprise three areas proposed .for'sprayfield expansion and one area previously used as a sprayfield and now desired to be reopened for that purpose. As indicated on Figures 2a and 2b,_ an old sprayfield area is called "Field D"; expansion near Field G called "Field E"; and two newly acquired areas near NCSR 170.4 called, the "Modlin Tract". The Modlin Tract has about 114 sprayable acres out of about 300 total acres; the other two areas are much smaller. J Findings - General Figures 1 ai%d 2, attached, show the general location and soils of the relevant landholdings of Mountaire Farms Inc., in Robeson County, NC. The sprayfield .areas are west of NC. 71, -immediately north of Mountaire Farms, Inc., south of NCSR 1704, and due west of the NCSR 1749_intersection with NC 71 near the plant entrance. The entire -tract 'exists on -the Coharie geomorphic surface, elevated about 200 feet above'Sea Level. The tract drains to the southwest, to Big Marsh Swamp. Figure 1 clearly shows this relationship, and shows the relationship of the tract to nearby county lines and dwellings. Overall slope on the tract is less than 6_percent,.but minor areas of steeper slope exist at the edge of drainageways. •� -� i•_y � ♦ate" _: 1 �'�'`••it." t�/-.. a: _.,�i' �--�- — r- � }�,.

Because of their nearness to, dissected relief, most of the soils,are well- or�.excessively well -drained. This means that seasonal high water tables (SHWT) in such soils are deeperthan 'three feet beneath -land surface.. Farmers' -,have historically sought these soils for agriculture 'and the drier -soils have been ,cleared.. Wetter soils have been allowed to vegetate with second growth woods. Areas of .old field border also exist in woods, but generally are not of wet soils' Soils proposed for.use as receivers of treated wastewater are in the Goldsboro, Lakeland, Norfolk, Wagram, and Wakulla Soil Series:" All these soils 'have thick sandy loam and loamy sand .surfaces overlying B-Horizons (subsoils). The difference between the soils is largely in clay content of the B-horizon and depth to that -horizon. Wagram., Norfolk, and Goldsboro soils have sandy clay loam B-horizons at depths from about 17 inches beneath land surface in Norfolk and Goldsboro soils to about 33 inches in Wagram soils. Pocalla and Wakulla soils have lighter -textured B-horizons of sandy loam or loamy sand at depths of about,24 inches beneath land surface. Depth td morphologically-inferred,;seasonal'high water table. (SHWT) is -about 38 inches`' beneath land surface. Mottles indicative of slowed water movement of course.occur at horizon transitions but, are. not interpreted'-. as SHWT.. In 'Goldsboro B-13 soils, SHWT is 26 to 30 inches beneath land surface, while in Norfolk soils SHWT is deeper than 36 inches. Soils have dark grayish brown surfaces ranging from 7 to 13 inches thick overlying E horizons of 5 to 11 inches thick. These combine to form granular structured "topsoil". Soils in all Series extend to about 60 inches beneath land surface.' Subsoil horizons are weakly structured with subangular blocky and granular peds. No restrictive horizons in the sense of DHS terminology occur. .However, because clay content is higher in subsoils than in surface soils, all subsoils are more restrictive to downward water movement here than are surface soils. Because of this, hydraulic load should be applied'at no i more than 0.75 in/hour, at a rate determined'by rainfall and water balance on a monthly basis. The addition of wastewater to the site is not so readily determined by a single number (the weekly average) as -it is by the interaction of several values. The weekly average presumes that evaporation and rainfall occur as shown in the water balance, and statistically over very long periods these variables do occur in such,a relationship. Significant deviations can occur, as.was the case with the wet Spring season in 1997, and the deviations mean that weekly or monthly totals must be adjusted to compensate for excess rainfall or decreased evaporation, and may be adjusted for 11decreased rainfall or increased evaporation. l B-14 The effect of variation in' evaporation is not as noticeable as is the variation in rainfall, partly because few observers separate cause and effect in these -two variables. Just because it is very hot and dry in Robeson County in July, for example, does -not mean that, wastewater can be put out in unlimited quantities. Usually soil drainage (water movement through the soil) compensates for minor variations in evaporation except when the ground is frozen or dry, and. on this site .soil. drainage is rapid. The particular attention must be paid to,rainfall and its variation from that projected in the water balance. An accurate 'rain gauge should be used by the operator to f for the, week or weeks immediately record the total rainfall before wastewater application is -planned. Relative to the Precipitation and Allowable -Irrigation coiunui5 �L �_• ----- balance adjustments must be made to decrease application if 'weekly average for the month, and of course rainfall exceeds the; application can be increased if rainfall is less than the weekly average. for. the month. Because no one can know what will happen in the third week, of a month -when application is being' made the first. week of a month an operator is ,always "playing catch up",. For example, each week of'1997's=Spring the operator would have to have held wastewater rather thanspraying it out; and could have caught up during the -excessively dry summer. Ultimately the operator and'.operator experience and ccess of the application procedure adjustments determine the su B-15 because spray irrigation is an agricultural operation subject to whimsy of weather and crop: Designers try to 'provide storage sufficient to hold the volume represented as the statistically projected amount that can reasonably be expected to need storage based on long-term trends. ,As noted previously most systems can count on soil drainage, as can this system. Is the storage sufficient? It appears so based on acceptable practices, but the operator must be striving to empty the lagoon in the dry season, knowing that going into the wet season with,a full lagoon will be fatal to system operation. Recent news reports showed that animal waste systems which overflowed did so partly because the lagoons were full of effluent at the start of the wet season. Reports didn't disclose if the lagoons were too small to start with., if they had insufficient storage, or if they just were not emptied during the summer preceding the wet season. Statewide the general trend is for an operator to pump, wastewater until the wastewater ponds or runs off the field. Here it will neither pond nor runoff quickly! To start the system up, measure input the week before. Review rainfall records the year before application is commenced. Accumulated deviations plus or minus should be used to establish the first loading, and all subsequent ones. Adjustments are possible as the system operates and the operator gains experience. If a request for higher loadings is made, the request should based on evaluations of sprayfield performance with B-16 regulated amounts of wastewater compared with rainfall. If complaints are made that the field won't take the planned yearly total, such complaints should be accompanied by records showing amount applied in relation to rainfall. Obviously if it.rains excessively the planned amount cannot be applied, and if this is a continuing trend counter to long-term existing records on which the system was planned, either more storage or more field will be needed. Doubtless the cumulative and weekly loadings are high compared to the Piedmont, or compared to clay-subsoiled sites elsewhere in the state. This is because the Mountaire site has soils comprised principally of relatively deep sandy materials overlying loams and sandy clay loams. Such soil conditions may tempt the inexperienced to load such sites at the rate that sands alone may pass water. This is not acceptable. The reason is that because of low hydraulic gradient, applied- wastewater will initially mound beneath the soil surfaces before redistribution occurs. Because of this it is imperative that loadings be made with wide between -event intervals. Such practice will allow the rapid permeability of the soils to effect redistribution and re - aeration.

Small grains can be produced :on a. wide range ',Of soil types and conditions'. but are best suited.. to deep, well -drained soils Waterlogged or flooded fields impair'root development;, nutrient uptake, growth, and final .yield. If the crop has to be planted in poorly drained soil, rye and triticale 'usually grow better -than wheat, barley,,. -,or oats..:. Soil Texture The best soil textures for. small grains range from sandy loams to clay, loams'. ' Sandy soils do not have the yield potential of loam soils, especially during seasons with drought or moisture stress. However, wheat grown on sandy .soils has a tendency to be .more responsive to intensive management. practices.., To. improve and maintain soil structure, use proper erosion -control techniques and crop residue management. -2- Production Problems Sandy and Fine -Textured Soils An extended, period -of 'low moisture or low temperatures following seeding, may lead to poor and uneven germination. Until a good ground cover is established by the small grain crop, •wind erosion may occur. The use of field wind breaks helps reduce wind erosion problems. Sandy soils'usually.require more nitrogen and -potassium to obtain good yields. Clay Loams and Clays If I seedbed, preparation is poor, resulting in shallow; uneven planting and poorly covered seed, ,heaving or ,spewing of -the small grain can occur. Shallowly planted seeds may develop roots near the surface, which increases the possibility of injury when the.soil freezes; with recurrent freezing' and thawing, plants with A --few short roots will,-beforced,(heaved or spewed) out of the soils and stay on the surface to die. This condition is found mostly in the piedmont because of the shrink -swell capacity of'some-soils. Timely and uniform small grain establishment offers significant erosion control when soils are sloping and erodible. - 3'- Other problems common to all areas include ruts, compaction; and traffic hardpans, especially.in. light-colored.sandy soils of the coastal plain; occasional. herbicide carry overs, and pH and nutrient..deficiencies Seedbed Preparation and'Tillagd. Poor seedbed preparation is' commonly. associated with poor stands and low yields. Conventionally tilled seedbeds for small grains should be relatively smooth. and. firm with a.- minimum of previous crop residues.. This ideal seedbed makes it easy to achieve a uniform, shallow seeding depth.with.good seed coverage.' A good seedbed will aid germination and root development. Many kinds of equipment can be used to prepare good seedbeds for small.grains. These include plows (chisel or moldboard); disks (tandem or finishing); spring -tine cultivators; harrows; and drags {cultivators or cultimulchers). The type of. soil and its condition, previous .crop residues, and equipment available determine the method and number of operations needed to prepare an adequate seedbed,.. Seeding is.usually done by drilling, although broadcasting without soil incorporation or overseeding into a standing corp sometimes results .i:n acceptable stand establishment. Seedbeds are prepared by using conventional, minimum; or no till practices. Conventional tillage uses a combination of cultivating' equipment. Fields with excess vegetation require conventional tillage, including plowing. Minimum tillage is simply �` diskng,once or twice followed by planting. -4- Deep tillage, chiseling, or bottom plowing will help to break hardpans and turn under crop residue, which reduces the chance of disease -and insect -problems. Deep tillage generally improves --".root development and. increases nutrient -and water- availability,: ; particularly in seasons. of. stress. "However, in some research studies;., ,,the yield benefit from "chisel or :bottom. plowing does not greatly exceed' -the extra -costs involved. No -till small: grain seeding requires -a special drill.. "Several makes and.models'of no=till drills -are now available. When using the no -till method, several consideiations.are pertinent: A. Can the drill achieve proper seeding depth and coverage?. B. What is the amount and type of -residue? .. C., How will no-till'affect.the weed population? D. There is a possibility -of increased incidence of disease and.insect problems, such as scab,from small grain residue or a'n'infestation of Hessian fly. E. No -till small, grains. may need more nitrogen. F. ' With proper, management, small." grains planted" ri'o=till can produce the same yields as' conventionally, planted small grains -with less work"and less erosion. No -till small"grain.production' will reduce fuel, machine, and labor .costs, but the costs of special equipment and chemicals may offset the savings. Rotation and Benefits Planting .small grains" in the, same field each " year leads to - increased disease and weed. problems and should not be done. Instead, rotate'small.grains with forage.; 'This benefits both the small grain-. and the other crops in rotation. Small grain crops , help to, control' erosion,- reduce the possibility of residual nitrogen moving to groundwater,, and reduce pest damage to. other crops in 'the rotation. An example.,:.of a good two-year rotation 'is . small; grains, (particularly wheat) double -cropped with soybeans, followed ,by corn the next spring and wheat .again, in''the fall. Certain forage crops can also`be a part of a rotation or can be seeded,as a companion crop, with small grains.1 soil .Fertility Management General:.Fertilizer Recommendations General fertilizer suggestions (in 'the absence of soil test' information) have ,been developed from a„ `review of thousands.; of small grain soil tests compiled from the -North Carolina Department of Agriculture's soil test .summaries. The -summaries in the . coastal" plains suggest that from 200 to 250 -pounds per acre of ,3-9-18 fertilizer, or its' equival.ent,,should be applied at.planting time. Additional nitrogen arid`.potash may be needed. Usually,, "30' to ,50 pounds _of nitrogen per acre at planting and 80 to 100 pounds of potash .per acre, are sufficient. -6- 'SRecific Nutrient Recommendations Nitrogen Topdressing should be done. -between mid -February and mid -March. The suggested rates for topdressing-(including nitrogen applied at planting.) .are given in the ';Table below: Split applications of nitrogen at topdressingltime have in some cases reduced severity of diseases and lodging and have increased yields. Apply one-half.bf the nitrogen in February and the remaining on in March. The success of this practice has not been consistent and depends`heavily'on varietal response,, soil type, and weather. Split applications of'nitrogen are more likely to"be effective in the coastal plains on sandy soils than in the piedmont on heavy, clayey soils. Some varieties of small grains respond to higher 'rates of nitrogen than'those suggested in the Page 6 Table. In general, small grains require the following pounds of nitrogen to .produce a bushel of grain: wheat and rye - 2.0 andtriticale'-1.5 and _7_ oats - 1.2, However, be'prepared to control•diseases and lodging by .using seed treatments and/or,-,foliar fungicides and growth., regulator for the appropriate ,crops. (See Extension Service publication AG-419-10,-Keys to'Intensive Wheat Management), for more, information.) Where small- grains will b'e 'grazed, apply nitrogen at a higher rate .(140 pounds -per acre) in a split application. ..Reduce the.amount of nitrogen topdressing i'f,the small grain ' follows peanuts and soybeans. Residues from these .crops may',,supply as much as 40 and 30 pounds per acre,.respectively., to thd,�small grain. Using this•manageme'nt technique can decrease production costs. Several satisfactory sources •or nitrogen are available for topdres'sing small grains,such as nitrogen solutions; ammonium nitrate, , ammonium sulfate,, 'and urea. Also check during the growing .season, for levels of sulfur, copper-, and.manganese.2 Weed Manaaement Weeds .in small grains.may reduce yield .and quality. A.weed management program,should'include'l) planting grain free, of weed' seed and. garlic; 2) using good, seedbed, preparation and proper fertilization,, 3)' -seeding,,.at the, proper time and rate,', 4) planting in narrow rows, and 5) applying herbicides when needed. Following good management practices minimizes the effects of weeds in small 'grain ,production. One of the best tools for suppressing' weeds in small grains is, a, -healthy, vigorous crop.., Shallow •tillage •before seeding will often kill giBrminati.ng.weed seeds .and. existing plants. ," If weeds germinate later, consider using'an herbicide. ME Competing weeds are mostly winter annuals that germinate in. the fall or 'early .winter .and perennials' such as wild garlic and curly. dock. Winter annuals include 'broadleaf ,weeds and annual (Italian) ryegrass. Many of these'weeds'f.ound in -small grains are described and pictured in Extension -.Service publication.-AG-108, Identifying Seedling and Mature Weeds "Common. in the -Southeastern United.States. Herbicides Herbicide selection depends -:upon the.specific weed problem, the small grain involved.'(since the different small grains vary"in their tolerance to -different herbicides), and time'of application.- Generally, the combination of.Banvel plus 2,4-D amine will control a greater number of `different winter annual 'broadleaf weeds than 2, 4.-D alone. This, 'Combination may. .be tank mixed by, the grower."„ Hoelon -and Harmony Extra are, also available for use on."small grains Hoelon controls 'ryegrass"in-wheat, and, barley but does not control -broadleaf weeds.

MOUNTAIRE FARMS INC: LUMBER BRIDGE; NC Introduction A well -established healthy cover crop'. of Coastal'°'Bermudagrass (Cynodon dactylon L. Pers.)'which is -referred to, in the following as "Coastal" will be grown''and harvested on this site. Areas. proposed for spray irrigation are generally'ridgecrests and,upper sideslopes. The deep' sandy soil 'surfaces would likely present drought problems to most.crops, but Coastal Bermudagrass has been proven to be a good performer on such sites, removing nitrogen and keeping cover on the soil. Attached ' as 'an, appendix to this hay., guide :Is an unpublished guide to forage nitrate content. This'is attached.because if sale of -the hay is contemplated, hay testing for nitrates should be done to ensure non -toxicity to animals,' and it is. difficult to locate qualitative data ranges for comparison. Hay Management' j Use a soil test -as &'guide for applying P, K and "lime. Each. ton of dry bermuda.forage contains about 40 pounds of-N and'K20, and 12. , pounds P205 .. Therefore, yields of 5 to 8 tons per acre — require much fertilizer.. :Hybrid.bermudagrass responds well to .. heavy fertilization. Marked yield. increases of hay have been obtained from about 200 pounds N..per.acre per year (split'in`3 to 4.applicati6ns) on the deep'sandy soils of the Sand Hills of -North _ Carolina.` Additional, increases. have resulted -:from 300 to 400' pounds'N-per acre per year (split'in 3 to 4-'applications) on the less sandy soils of the upper,Coastal-Plain in (Table 1). li;Il16 1 Y.}e:1(i, i'oi;cenL 'xuifu 11'roLuii;.. mid Ne:rce:nL AppurunL NiLroqun lice:uvc:ry e;s Tnflue:ncL-d by ILiLu of NiLrul)uit Applical.iun Iuu'I e;c;iLie;n:: in Nc;cta; (:i;rell illi).

Coastal ,Bermudagrass hay-" f~_l production is probably 'around 300 pounds per"acre per ,year where growing 'season., length and . climate are at' optimum " for the grass. When using this quantity of N, for':average conditions of .P205,and K20, requirements can be met. by one application' of 5GO to-'800 lbs/AC of 0-10=20 fertilizer. The spray irrigation will supply much of the requirements most farmers have to satisfy with fertilizer. Soil test results ''and experience,suggest field°soil pH's of between 5.0 and 6.0 with P and K indices from 4 to 40. For proper hay quality, about 75 lbs. of N,.:90 lbs. of,P; and 240 lbs. K:are needed after -each hay.cutting. While 0.5 T/AC lime is recommended,.probably an application of 3 T/AC initially will be needed to bring fields to,regulatory pH level. In general, lack of adequate K 'may produce the most, severe problems, which include winter kill, low yield, and leafspot.. disease. ."Harvest'Management The . general rule ,of thumb is. to cut bermudagrass at 4 ..to - 6 week intervals or when it.'is approximately 12 to 15 inches tall, , whichever, comes first. Once the forage is 12 to'15 inches tall, a ,delay of 2 weeks or. more can result in the loss of, regrowth as well . as loss of quality of forage.. In .general, the wise manager will have sufficient fields to allow accumulated growth to be harvested in'the,form of hay when it reaches the desirable stage of growth. -13- Fall management is important in maintaining vigorous stands I and preventing winter injury, particularly in the Piedmont. Bermudagrass should reach the winter with 3 to 4 inches of growth (no more is necessary) to serve as insulating against winter damage. This growth should not be grazed or removed prior to -the period of February 15 to March 1. Early spring growth is encouraged by the removal of the dead material from -the previous year. Cut and rake or burn the dead material in February or march before sludge application. To summarize the management practices for hybrid bermudagrass hay production consider the following points: (1) Soil test and apply. the necessary lime, to maintain pH 6.0. (2) Nitrogen should be applied at -the time growth begins in the spring (March/April) and after each harvest except the last. Refer to Table 1 as- a guide for nitrogen to obtain yield goals. (3) All of the phosphorous and potash may be applied in the spring. However, on deep sandy soils tine pvt�abll 5ilvu.-A be split, 1/2 in the spring and 1/2 after the second cutting, especially if the yield goals is above 5 tons per acre. (4) Burn old residue 2 to 3 weeks before bermuda breaks dormancy to insure rapid spring growth. (5) Make the - first cutting when plants reach 15 inches in height and make cuttings every 4 to 6 weeks thereafter depending upon the quality of feed needed.
