' Oroville Gold LLC Composting Facility Required Information ' I General Background Information 1. Project Location (including Township, Range and APN where appropriate) — See Figure 1. i Facility Location: The site is located southeast of the City of Oroville, Butte County; California. The facility is located in the NE'/. of the Palermo 7.5', Quadrangle at the juncture of Sections 29, 30, 31, and 332, Township 19 North and Range 4 East, Mount Diablo Base and Meridian (Figure 1). The site is bound by Union Pacific and Southern Pacific railroad rights of way on the west, north, and east, and by Ophir Road on the south. Access to the site is from ' the south via Ophir Road and north on the interior property road (Figures 1 and 2). Revised legal descriptions have been prepaied and are attached as Appendix A. ' ' 2.

Need for project: The addition of an organic compost facility will have enormous benefits for the local community, both economically and environmentally. The quantity of waste that can be recycled and, most importantly, diverted away from landfills is limited only by the facility's operational capacity to process it.` California's legislature has set high targets "in its drive to reduce reliance on landfills. Local `compost facilities in other California counties have been highly successful in helping local government achieve the waste diversion standards mandated by the State. Local businesses that are faced with increased regulations regarding how to manage their waste appropriately will have a viable option to recycle via composting available as early as this harvest and processing season. Oroville Gold will provide a quicker and less expensive option that does not involve the capital expense of"infrastructure improvements at a time when many businesses are under considerable financial pressure. ' The compost produced will be a high-quality soil amendment that repairs and replenishes nutrient losses in the native soil. This will greatly assist the agricultural growers in this area. Its local availability will reduce transportation costs, benefiting both growers and the environment. Fuhhermore, development of the facility will create new job opportunities (facility employees, trucking and associated services). Finally, the recycling of landfill wood waste is both effective and environmentally productive as a means of assisting with the clean closure of the closed LP site. 5. Service projections for the life of the facility taking into account AB 939 waste diversion mandates The site will be capable of recycling 531 tons of material per day using a permitted 25 -acre composting pad. However, unlike a landfill facility, composting has an indefinite life span as no material accumulates on site. As demand increases, the composting area could be increased, subject to the necessary approvals, to help the County meet future increases to the waste diversion mandate. 6.

The land uses which are authorized adjacent to, or near, the facility are compatible with the establishment, or expansion of, the solid waste disposal facility or transformation facility. 10. Initial Study and environmental checklist — See checklist below. A final initial study will be completed by Planning Department using information provided below. II. Project Description 1. Site Description o topographical map — See Figure 5 o size of site (acres) — 68.7 with an active composting operations area of approximately 25 acres o site design, including but not limited to site/layout map, active compost area, feedstock storage areas, well locations, drainage features, and property boundaries — See Figure 3 o total site capacity for active compost (in cubic yards) A separate stockpile and retail sales area, approximately 6 acres in size will be located in the south west corner of the facility immediately west of the site entrance (Figure 3). The area has a maximum storage capacity of 47,000 cubic yards of finished compost. ' The active composting operation will utilize approximately 11 acres for the ASPS and/or Turned Windrows; the proposed areas for each process are approximately 6.3 acres for the ASPs and 4.6 acres for the turned windrows. An ASP system can receive approximately 6,700 cubic yards per acre of feedstocks; a turned windrow system will be able to receive approximately 2,400 cubic yards per acre of feedstock. This gives a maximum volume capacity of approximately 53,000 cubic yards. The volume of incoming feedstocks maybe reduced by a factor of five by the end of the composting process. • The composting process takes approximately 90 days to complete. After an initial start-up period, the facility will be able to take in 5 cubic yards of feedstock materials in order to produce 1 cubic yard, of finished material; the maximum production capacity of the Oroville Gold compost facility will be the import of approximately 438,000 cubic yards of feedstock material per year, resulting in the production of approximately 88,000 cubic yards per year of compost. If the entire 11 acres were dedicated to the more space -efficient ASP method, the maximum production capacity. would increase to an import of approximately 600,000 cubic yards of feedstock material per year, with the resultant production of approximately 120,000 cubic yards per year of compost. o average and maximum quantity of individual types of feedstock processed in tpd (green material, manure, MSW, wood chips, special waste etc.) Wood Waste (532 lbs/cubic yd): 96 tons/day Agricultural Material: Cattle manure (1458 lbs/cubic yd): 52 tons/day Agricultural Material: Poultry manure (1400 lbs/cubic yd): 52 tons/day Green Material (550 lbs/cubic yd): 65 tons/day Residential Food Material (1700 lbs/cubic yard): 53 tons/day Commercial Food Material (2000 lbs/cubic yard): 213 tons/day I These materials will be combined for composting in order that a Carbon to Nitrogen Ratio (C:N) of 30:1 is obtained. Using the aveiage moisture values and dry -weight nitrogen and carbon compositions (http://compost.css.cornelLedu/Composting_homepage.html), this ' provides a mass ratio of 1.8 : 1 : 1 : 1.3: 1: 4.1 of wood waste: cattle manure: poultry manure: green waste: residential food waste : commercial food waste. The residential food waste was assumed to be comprised of 50% food waste and 50% green waste (EPA Municipal Solid Waste Generation, Recycling, and Disposal, in the United States: Facts and Figures for 2008). This ratio maybe adjusted depending on material availability. This gives a total estimated daily tonnage of 531 tons of feedstocks received once the facility is at full capacity. This in. turn means that over the course of the facility's 264 operating days per year, approximately 140,000 tons of material (for 264 days a year) will be received. Assuming a. volume reduction- of, eduction •- of approximately 80%, this will generate 28,000 tons (56,000,000 lbs)'of compost. The quoted C/WMB conversion factor for compost is 800 lbs/cubic yard. Therefore, Oroville Gold will generate 70,000 cubic yards of compost per year. o maximum quantities of active compost, feedstocks, amendments, and additives on hand at one time (in cubic yards) Maximum estimated quantities (in cubic yards) are as follows: Estimated ` Estimated Maximum Maximum Stockpile Dimension Quaritity (lengthy base x height 'K* Onsite Storage Material Method of Storaqe at peak) Location (cubic vards) Timeline turned windrows windrows 200'L• x 15'13 x 6'H TW 25,000 3 months aerated static piles ASPs 700'L x 90'B x 8'H 'ASP' 62,500. 3 months finished com' ost .. stockpile 5001E x •125'6 x 20'H" FM .47,500 8 month's wood waste stockpile 3001E x 80'13 x 20'H SAA • 11,278 indefinite cattle manure stockpile 1201E x 30'B x 15'H SAA 960 2 weeks poultry manure stockpile 601E x 30'13 x 15'H SAA -500 1 week green waste stockpile 5001E x 40'13 x 20'H ' SAA 7,273. 1 month residential food waste stockpile/bins 351E x 20'6 x 10'H SAA• 125 ' 2 days commercial food'waste stockpile/bins 120'L'x 20'6 x 10'H SAA 426 2 days lime stockpile 201E x 20'13 x 10'H +.

Clean closure site adjacent to the compost facility, public self - haul Cattle & poultry manure from local farms, ranches and dairies; public self -haul Curbside collections and transfer stations; public self -haul Curbside collections, restaurants, grocery stores, special events, and institutions; public self -haul a compost facility can continue indefinitely as there is no current land use Adjacent to the proposed Oroville Gold composting facility, there are three waste management units (WMUs) undergoing a clean closure process. This process operates under the Waste Discharge Requirements specified in the Central Valley Regional Water Quality Control Board (CVRWQCB) Order No. R5-2007-0042. The WMUs consist of various types of wood waste including sawdust chips, bark, cleanings from the log decks, and cover materials. As pan' of clean closure of the landfill, Oroville Landfill Properties, Inc. will be. excavating the wood materials from the WMUs (WMU #1 and WMU #2). Historically, though forming part of the permit landfill area, the location proposed for composting has remained unused and was not within the designated WMUs. o historic land use The former Louisiana Pacific Sawmill Class 3 landfill is located to the immediate north of the composting operation; Southern Pacific Railroad, with vacant and light industrial land, to the east; Ophir Road and Norca/ metal fabrication, a scrap yard, and other light industrial facilities to the south, and Union Pacific Railroad, light industrial and Marysville-Baggett Road located to the west. o current zoning M2- Heavy Industrial o detailed environmental setting, including but not limited to climatological factors,, physical setting, ground and surface water, soils, surrounding land use Oroville experiences hot summers and mild winters with average high temperatures ranging from 55 degrees Fahrenheit in January rising to 96 degrees in July and August. The site, slopes gently, as shown on Figure 5. No surface waters flow through the site. Groundwater elevations range from 126 feet MSL to 177 feet MSL. The direction of groundwater flow is toward the southwest. The groundwater gradient measured during first quarter 2004 was 0.01 feet per foot. The designated beneficial uses of the groundwater, as specified in the Basin Plan, are domestic and municipal supply, agricultural supply, industrial service supply, and industrialprocess supply. The soils at the site are classified by the United States Geological Survey (USGS) as Oroville-Thompson flat complex, which is a mix of moderate to very deep, poorly to moderately well drained soils -that formed in alluvium derived from metamorphic and igneous rocks. The Site is bisected by a northeast trending ridge which serves as a natural drainage divide. Surrounding land use is industrial, both light and heavy. The boundary of the compost facility will be at least 800 feet from commercially -zoned districts. There is a minimum distance of 2,000 feet from the proposed composting area to the closest residential areas, and one mile to the nearest school. o classification of disposal site if sited on a landfill (SWFP #) SWIS # 04 -AA -0009 On'September 1990, the Regional Board issued Order No. 90-266, in which the facility was classified as a Class N Waste Disposal Site for the discharge of wood waste and ash in accordance with the regulations in effect when the Order was issued. o type of users of the site (commercial, public, private) Oroville Gold LLC intends to be available for commercial, and public use. o construction description (e.g. grading plan, drainage plan) Grading& Drainage plans are currently being developed to reflect the final permitted design. o list of approvals required by federal, state and local agencies in order to implement project CEQA Review Document (Prepared by the Department of Development Services) Compliance with CEQA, certified by the LEA and the California Integrated Waste Management Board Solid Waste Facilities Permit (SWFP) from the LEA and the CIWMB Waste Discharge Requirements and Storm Water Permit from the California Regional Water Quality Control Board Authority to Construct and Permit to Operate from the Butte County Air. Quality Management District 2. Design and Operations o verification of compliance with USEPA, California Department of Health Services, Department of Toxic Substances Control, Air Pollution Control District or Air Quality.Management District, Regional Water Control Board, Integrated Waste Management Board, and State Minimum Standards for solid waste handling and disposal requirements. Verification will occur during the permitting process. o method of composting o construction Using wheel loaders o windrow, static, "in vessel" Turned Windrow Composting The Turned Windrow composting process will be used for all material feedstocks and is particularly useful as a method of ensuring a consistent 'recipe'. After grinding and moisture conditioning is complete, the feedstocks will be arranged into elongated windrows using a, front-end loader. The dimensions of the windrows. will be approximately two -hundred (200) feet long, fifteen (15) feet wide, and six (6) feet tall. Windrows are separated by approximately. eight (8) feet to allow suf icient.room for access to allow the management and control of moisture conditions and dust suppression.. In accordance with Title 14, Chapter 3. 1, Article 1, Section 17868.3 (b) (3), active compost windrows shall be maintained under aerobic conditions at a temperature of 55°C (131* F) or higher for a pathogen reduction period of 15 days or longer. During the period when the compost is maintained at 55 ° C or higher, the windrows shall be turned (i.e. mixed and aerated) a minimum of 5 times. At least one temperature reading shall be taken each day during the pathogen reduction period per every 150 feet of windrow, or fraction thereof, or for every 200 cubic -yards of active compost, or fraction thereof. The windrows will be turned and moisture will be added as necessary to maintain the composting process. Primary composting is considered complete when internal -temperatures have declined below approximately 43°C (105°F), and remain there even when the compost is aerated and maintained under optimum moisture conditions. Residence time of a typical windrow will vary based on management intensity,, time of year, weather, and other operational factors but will be a minimum of 15 days and will likely average around 20 days. In the unlikely event that there is a delay in processing, windrows will be deconstructed no more than 3 months after original construction. Aerated Static Piles Using the extended aerated static pile layout (On -Farm Composting Handbook,, 1992),' feedstock material is placed in an, initial static pile approximately 16 feet long by 90 feet wide by 8 feet tall with aeration piping placed underneath the width of the pile. Additional cells are then added along the 90 -foot face with additional aeration piping placed every eight feet (Appendix D). Assuming a 90 -day processing time and the import of 1,000 cubic yards of feedstocks a day, the pile may be extended 40 feet per day. As the size reduction of the initial ASP occurs, the piles will be rebuilt to the original configuration; this will free up space to build new ASP with fresh feedstocks. To maintain aerobic conditions, air will be either forced with positive pressure through the aeration piping out through the surface of the pile in order to provide fresh air from .the center of the pile outwards, or drawn in using negative pressure to provide fresh air from the exposed surface of the pile inwards towards the aeration pipe. The type, timing and duration of aeration will be based on the three main operational parameters of temperature, moisture content, and oxygen levels. Temperature responds with respect to moisture and oxygen levels; controlling temperature is achieved by adjusting either moisture and/or aeration levels. Aeration serves to lower excessive temperatures and remove moisture. During the pathogen reduction process, a temperature range of 55°C (131 °F) to 59°C (138°F) will be maintained in the zone specified in Title 14, Chapter 3. 1, Article 1; Section 17868.3 (d)(2)(B)) for 3 days; that is, the aeration system will be activated if the temperature exceeds 59°C and deactivated when the temperature reaches 55°C. After the pathogen reduction process has been completed, temperatures will be maintained between 45°C to 59°C in order to maximize the decomposition rate. At least one temperature reading, shall be taken each day during the . pathogen reduction period per every. 150 feet of pile, or fraction thereof, or every 200 cubic -yards of active compost, or fraction thereof; more readings will be taken in cases of high temperature to ensure the pile is being cooled. Temperature readings in addition to those required will be taken to measure conditions deeper inside the pile as well. The decision to use either positive or negative pressure will be based on conditions inside the piles as well as climatic conditions at the facility. For example, if temperatures exceed 59°C deep inside the pile but are within the above specified limits at the periphery of the pile, positive pressure will be used; if the periphery of the pile requires more rapid cooling than the core, negative pressure will be used. The same tactic can be used for controlling moisture as well; any applied aeration will have a drying effect on the compost. When negative pressure is used, a condensate trap constructed from a 55 -gallon drum or barrel will be used to accumulate moisture extracted from the pile. The condensate will then be either reapplied to moisture condition feedstocks or stored in the detention basin. Initially, the aeration system will be constructed of perforated piping laid underneath the pile in a bed of porous material (e.g. wood chips) at approximately 8 -foot intervals; the perforated interval will be 70 feet in a 90 -foot wide ASP. Typical piping used for this process is 4 -inch diameter PVC. Each length of pipe will have an individual blower attached for maximum process control while in the pathogen reduction phase. The typical blowers to be used are 1/3 horsepower with a flow rate of 150 cubic feet per minute at 0.5" of static pressure. These blowers are small and relatively inexpensive when compared to a large manifolded blower that would be used for a full-scale automated system, and will be added as production increases. If negative pressure (suction) is required, each blower will have its own associated condensate trap and biofilter. The bio/fl/ter will consist of an approximately 2 -cubic yard pile of compost placed over the exhaust hose from the blower. The compost used for the biofl/ter will be replaced on a bi-weekly basis. Blowers and their associated condensate traps will be moved as needed to provide aeration; bioNters will be constructed as needed (Appendix D). A layer of insulating material, 6-12 inches thick, will be used to cover active compost to minimize the risk of odor generation. Suitable insulating material includes stabilized compost, compost "overs'; and soils. As a further odor minimization practice, the exhaust from the blowers will be directed through a biofl/ter. The biorilter will be made from stabilized compost, finished compost, or soils. In accordance with Title 14, Chapter 3. 1, Article 1, Section 17868.3(b)(3), all active aerated static compost piles shall be covered with 6 to 12 inches of insulating material, and the active compost shall be maintained at a temperature of 55° C (131° F) or higher for a pathogen reduction period of 3 days. Primary composting is considered complete when internal temperatures have declined below approximately 43°C (105°F), and remain there even when the compost is aerated and maintained under optimum moisture conditions. Residence time in the Aerated Static Pile will vary depending on the season and sales demand but will range from a few days to up to 3 months. o forced air, mechanical Both.

If a' visual load check in a contamination level greater than 1.0 percent, "a representative sample will be taken, physical contaminants will be collected and weighed, and the percentage of physical contaminants determined. The load will be rejected and unloading will not be allowed if physical contaminants are greater than 1.0 percent of total weight. The material will then be backhauled to the originator. Specific training criteria for staff undertaking the load check are described in the Load Checking Program. Should physical contaminants, including hazardous waste materials, be inadvertently received on site, they, will be immediately returned to thegenerator, if possible. If the generator of the material is unknown, the material will be placed in a covered prohibited material bins in the hazardous or non -hazardous waste storage locations (Figure 3). The hazardous waste storage location will be covered and secured and located on an impermeable surface with a containment berm. The non -hazardous waste storage will be on an impermeable surface and secured. The Facility Operator will arrange for appropriate disposal on a weekly basis of prohibited materials and any incidental hazardous waste or materials by an appropriately licensed hauler. The licensed hauler will dispose of the material at an appropriate licensed disposal facility which accepts the material in question. process (composting material) o type of test (temperature, moisture) Temperature, oxygen and moisture monitoring Temperature will be _taken with a stainless steel Reotemp compost thermometer with a 36" probe or equivalent.

Once a mixture is actively composting, a basic squeeze test will be used to determine if there is sufficient. moisture for effective breakdown: a handful of the material will be squeezed tightly in the est. The material should feel like a wrung -out sponge, releasing at most only a few drops of moisture. Moisture content will be monitored weekly and before turning or pile reconstruction in order to determine if additional moisture is needed; moisture content will be maintained between 45% and 60% as determined by the method above. Moisture content may be adjusted by the following methods: addition of either fresh or process water, addition of moister or drier materials, and aeration (i.e. turning or by of blowers).. A 45% to 60% moisture content should be maintained year-round, gas -permeable tarps may also be employed in the case of extended rainy periods. Excess moisture that drains from the piles or collects in condensate traps will be collected in the detention basin. Oxygen levels will be measured in coordination with temperature readings with a compost oxygen probe (e.g. the Woods End Oxygen Probe or equivalent.)

A loop of fire hydrants on 400' centers will be situated in proximity of the.berm around the active composting area; fire hydrants will also be located around the rinished material storage and retail sales area (Figure 3). The berm slopes will be kept free of brush and combustible materials within 50' of the centerline of the road, creating a Fre break 100' in width. Signage regarding standard fire safety information and emergency contact information will be provided at the scales, facility office and other locations as needed and/or mandated by the local agency. All equipment will be fitted with spark arresters in accord with applicable vehicle regulations and carry fire extinguishers. Fire extinguishers will also be located in hazardous materials/waste storage areas in order that travel distances do not exceed 50' per NFPA 13.6.6.4.4. All facility structures will have fire protection as mandated by the California Fire Code or NFPA. Equipment used in normal daily operations will also be available for use in emergency situations. Any additional standby equipment required by the local agency during the fire season will be provided. Open burning at the facility will be expressly prohibited. o vector controls The facility will implement a range of techniques to deter and control potential vectors at the site, namely rodents, birds, and insects. These techniques will include the following: • Use of gas -permeable tarpaulins and other covers to prevent access to active compostable material or finished products. In the case of active compost, the high temperatures within the compost will help to destroy any vectors that breach the covers; • Immediate or rapid grinding and incorporation of food materials and manures that will potentially be most attractive to vectors; • Regular grinding, mixing and turning of the windrows will act as a deterrent to vectors, particularly those seeking to nest; • Manual and/or automated noise devices will be installed to act as a deterrent to the bird population; • Fly traps and mouse traps will be deployed and adjusted as necessary on a daily basis to control flies and small rodents, • The facility will house a resident cat to help reduce any rodent population; and • In the case of heavy infestation, a professional extermination service will be used. litter controls Decontamination of incoming food and green materials will initially occur after these materials are unloaded and before grinding. The facility will employ a litter patrol as needed to remove litter that may cause a nuisance on-site. Final removal of contaminants occurs during the final screening process described in the Curing/Screening (Section 4). The litter is collected in appropriate waste containers and disposed of as part of the regular disposal process described in the Storage and Disposal of Waste Material (Section 6). Portable litter fences may also be used if wind conditions warrant. odor controls A variety of odor mitigation techniques are employed throughout the operation; these include immediate grinding and incorporation of potentially odiferous materials, the use of covers, biofi/ters, and aeration of the detention basin. If material is received in an anaerobic condition; it will be immediately mixed with carbonaceous material to improve oxygenation and combat odors. Once the composting process begins, odors are controlled primarily by the appropriate management of temperature, moisture and oxygen to attain and maintain aerobic conditions throughout the active composting phase. In particular, use of a windrow turner ensures a consistent, homogenized and oxygenized blend in the Turned Windrows thereby greatly reducing the potential for odor. The Aerated Static Piles are designed to include an insulating layer and a biorrlter system. Both are described in more detail in Section 4 above. Detailed mitigations for specific feedstocks and handling processes are described fully in the facility's Odor Impact Minimization Plan attached as Appendix F. By comparison to new feedstocks and material in the early stages of processing, stabilized compost presents no serious potential for odor generation as the odiferous compounds have by that point already been metabolized through the composting process. ' On-site housekeeping practices, particularly the prevention or removal of any ponded liquid and the appropriate use of covers for unprocessed material will also effectively eliminate or minimize odors. ' It should be noted that the Facility is surrounded by land used for in Tial purposes, with the nearest residence located over one-half mile away from the site. This characteristic further reduces the potential for off-site odor issues related to the composting operations. ' Should the facility receive an odor complaint, the complaint handling protocol,, fully described in.the facility's Odor Impact Minimization Plan, will be implemented. Where appropriate and possible after receipt of an odor complaint, the facility operator will implement targeted odor mitigations in an effort to remove odor and prevent any recurrence in the future. o dust controls A water truck is used to wet unpaved portions of the access road and high traffic areas at the site as needed. Water and equipment foi dust suppression is available at grinding, screening and dry material unloading operations area. Commercially available dust suppressant, such as Earthbind 100 or equivalent, will be applied to facility road surfaces on an annual basis. o noise and vibration control provisions Equipment noise levels at the facility do not exceed commercially accepted practice. The site ' 'is buffered by the surrounding trees, railroad and roadways from the other commercial and industrial operations in the vicinity of the facility. Facility personnel are provided with hearing protection equipment pursuant to State law and Occupational Safety and Health Administration (OSHA) regulations. o noise levels generated by the project (construction and operation) Machinery, outfitted with mufflers, eucalyptus grove, daytime operations only. o vibration levels generated by the project (construction and operation) ' None anticipated o _Weight scales Truck scales on site near entrance. o product storage o volume The overall size of the facility is approximately 68.7 acres. Around 25 acres will be dedicated to active composting operations. A separate stockpile and retail sales area, ' approximately 6 acres in size will be located in the south west corner of the facility immediately next to the site entrance (Figure 3). The area has a maximum storage capacity of 47,000 cubic yards of finished compost. Oroville Gold will be handling a total ' estimated daily tonnage of 531 tons of feedstocks once the facility is at full capacity. This in turn means that over the course of the facility's 264 operating days per year, approximately 140,000.tons of material will be received. Assuming a volume reduction of approximately 80%, this will generate 28,000 tons (56,000,000 lbs) of compost. The quoted CIWMB conversion factor for compost is 800 lbs/cubic yard. Therefore, Oroville ' Gold LLC will generate 70;000 cubic yards of compost per year. Assuming steady state operation (5 cubic yards of material in to 1 cubic yard of material out), the maximum production capacity of the Oroville Gold compost facility is the import of approximately 438,000 cubic yards of feedstock material per year, resulting in the production of approximately 88,000 cubic yards per year of compost. If the entire 11 acres were dedicated to the more space -efficient ASP method, the maximum production capacity would increase to an import of approximately 600,000 cubic yards of feedstock material per year, with the resultant production of approximately 120,000 cubic yards per ' year of compost.. o time Maximum 8 months for Finished Compost ' o location Separate storage and. retail sales area. o handling With wheel loaders o leachate containment ; Grading plans are currently being developed to reflect the final permitted design.. o low permeability barrier, pad liner, material type, availability, permeability, moisture content 2 ft. of low -permeable material compacted to 90%maximum density collection and containment system Collection pipes and detention basin to capture leachate for re -use. recirculation plan Zero discharge is required. After collection in the detention basin, the storm water and leachate will be used as process water for moisture conditioning blended feedstocks and compost piles. o erosion controls Geological studies indicate no impact to the site. Temporary erosion control will be achieved through construction quality assurance activities, which will be documented in the final grading plans which will be completed once approval of the site design is received. Everyday erosion control will be achieved through dust control measures, storm water controls and monitoring and other best management practices. o sedimentation controls, such as siltation basins and location of such controls Grading plans are currently being developed to reflect the final permitted design. drainage facilities (run-on and run-off) Existing Surface Drainage Plans Drainage at the Site flows via unnamed natural drainages to the Feather River which is located approximately one (1) mile west of the Site. The Site topography has been modified by extensive placement of waste materials. Despite the presence of the rills, natural drainages that are tributaries of the Feather River still control surface water runoff in the area. Existing Drainage Control A sump is situated on the former landfill's western border to the northwest of the operations buildings. It is a small, unlined pond with a capacity of approximately 10,000 gallons. 'Historically, this sump collected storm water run-off from a portion of the landfill facility, as well as wastewater from the hardboard plant, non -contact cooling water, boiler blow -down water, wash -down water from the plant buildings and pads, and run-off from the log deck. This sump is fed by two subterranean pipes extending from the former landfill facility. Per CVRWQCB Order No. 90-266, contact water (i.e., storm water run-off) from the WMUs is routed to unclassified surface impoundments for containment and evaporation. These impoundments were sized to contain all liquids generated during the winter period, plus the amount of precipitation from the 25 -year, 24-hour storm event and still maintain a minimum 2.0 -foot freeboard. Based on available information, it is known that Ponds 1, 5, and 7 still receive"and sometimes contain run-off. Other containment ponds were constructed at the southeast edge of the compost site to contain run-off which had come into contact with sawdust and wood chips placed nearby to act as mulch for a newly - planted eucalyptus grove. Upon completion of construction, an Industrial Storm Water Pollution Prevention Plan will be developed for the site. drainage plan (can be included with site map) See Site Plan, Figure 3 o method of handling special wastes (liquids, sludge, white goods) No liquids, sludge or white goods will be accepted at the facility. Feedstock material delivered to the facility by;company/commercial vehicles and public self -haulers will initially be received at the scale house located near the site entrance where th'e loads will be weighed and characterized with respect to material source and type. Incoming vehicles carrying feedstocks will then be received and the site attendant will direct haulers to the unloading area. Unprocessed feedstocks will be stockpiled between the receiving and turned windrow areas, as shown on the site design, Figure 3. Oroville Gold's policy will be to process and incorporate any feedstocks before any offensive odors develop regardless of the class of feedstock. Generally, any loads containing food materials will be processed and incorporated into Turned Windrows or Aerated Static Piles within 48 hours of receipt. In the unlikely event that this is not possible, these materials will be temporarily stockpiled in, and covered by, unground green material or wood waste in accordance with the facility's Odor Impact Minimization Plan. All green material loads will begin to be processed within one month of receipt Unprocessed feedstocks will be stockpiled between the receiving and Turned Windrows areas, as shown on the site design, Figure 3. The excavated wood waste will be transported to the composting operation using trucks; The.wood waste recovery,operation will be conducted at the WMUs. " Excavated'inaterial from the WMUs will be separated and handled under the existing Waste Discharge Requirements (WOR). The wood waste transported to Oroville Gold from the WMUs will be tested, prior to being accepted at Oroville Gold, in compliance with current WDR for the Clean Closure of Oroville Landfill Properties Class Ill Wood Waste Landfill, Order No. R5-2007-0042. ' o method of handling incidental hazardous waste The facility will have a Hazardous Materials Management Plan in place prior to the,start of operations"at the facility. Wherever possible, non-compostable material removed during ' load checking will be backhauled to the originator either via the delivery vehicle or the next'incoming vehicle from the same origin. Alternatively, waste materials that need to be removed from the site will be removed on a weekly basis. The facility operator will schedule pick up witha'licensed hauler. Storage locations are.indicated on Figure 3. Should hazardous waste or materials be'inadvertent/y received on site, they will be,stored in accordance with the facility's Hazardous Materials Management Plan and disposed of using a licensed hazardous waste hauler. A separate hazardous material and waste storage location is indicated on Figure 3. ' Any non-recoverable or non -marketable residues (for example, `compost 'overs' that have not been returned to the process "will remain stored on-site for no longer than 90 days. After this time, if confirmed that they have no market value, the compost overs will be transported to a landfill either for use as Alternative Daily Cover or'disposal. Physical Contaminants and refuse removed from feedstock, compost, or chipped and ground material shall be removed from the site within 7 days and transported to an appropriate facility.. 0 Exclusion — see above o Storage — see above o number of employees and duties Estimated to be 15 — Equipment operators, Mechanic, Garbage pickers, Office Personnel, and Management. o site improvements o. drinking water (well, municipal, bottled) Municipal ' o sanitary facilities " On-site septic o communications Telephone lines, cell phones o electrical provisions PG&E already available on site. 0 office building Already in place — approximately 2,000 sq.ft, building (shownon the attached site plan, Figure 3.) o risk of upset o contingency plan Equipment Failure ' The facility will initiate operations using common material handling equipment (primarily front-end loaders), which is easily replaced by rental equipment in case of equipment failure. Initially, grinding will occur using contract grinding services. Once the facility purchases a full-time grinder, contract -grinding services will be used in the case of equipment failure. In the event of a short-term power outage, the facility will suspend operations until power: is restored. Facility personnel will ensure a safe closure of the site by escorting members of the public and other visitors off site and posting closure notices at the entrance. Once the facility has been secured, personnel will leave the site and the facility operator will ensure the gate has been closed and locked. In the event of a long-term power outage, the facility will bring in emergency mobile diesel generators, e.g. a Baldor TS25 60HZ or equivalent, as required to ensure adequate aeration of the detention basin and any other mitigations designed to . prevent odor generation. The number of required, aerators depends on the quantity of ' retained liquid in the detention basin. Two 5 -hp aerators will be required for every one million gallons of liquid. One 18kW generator is sufficient to power 4-5 aerators. The total number of generators required on site for odor control purposes will therefore, depend on the quantity of liquid that requires aeration. The facility anticipates having a well as a source of water in addition to the existing supply from the local water district. This will ensure that if one source fails, an alternative source is available. If there is a failure in the local district water supply, process water will be supplied via the proposed well or trucked in using the facility water truck. Any leachate retained in the detention basin may also be used as process water. Emergency potable water will also be provided to ensure appropriate health and safety conditions can be maintained on site. Unusual Peak Loading The facility scale operator is responsible for determining when the facility's tonnage limits are being reached. If the facility is within 20% of the permitted daily maximum, the facility scale operator will notify the facility operator or other designated manager. In an unusual peak - loading situation (for example, excess delivery of green materials) where the facility is reaching its maximum capacity of non -processed materials, as appropriate the facility operator will either utilize additional contract grinding services for processing capacity or identify alternative organic facilities (for example, chipping and grinding or co -generation facilities) for re -direction of incoming material. If no organic processing alternative is available, excess tonnage will be directed to a suitable landfill. Finished material will only be stockpiled in the designated Finished Materials and Retail Sales Area (Figure 3) to prevent possible re -contamination. If the maximum storage capacity of the designated storage area is reached, excess tonnage will be directed to a suitable landfill. public health and safety The public will only be permitted to enter the Retail Sales area. The facility will employ the following programs to protect public health and safety: Health and Safety training for all employees (including Hazardous Materials Management Plan, Right -to -Know, Hazardous Communication Program, IIPP, OSHA safety, SWPPP, NPDES & Emergency Action Plan and Procedures). All equipment will have the proper safety equipment (e.g. backing beepers) and properly trained operators to insure public safety. employee health and safety New employees will receive Health and Safety training within 30 days of employment and annually thereafter (including Hazardous Materials Management Plan, Right -to -Know, Hazardous Communication Program, IIPP, OSHA safety, SWPPP, NPDES & Emergency Action Plan and Procedures). Safety Meetings will be held monthly, job specific tailgate safety meetings will be conducted as necessary. All employee training and safety meetings will be documented and records will be retained for three years after employee termination or closure of the facility. Records will be maintained in the facility office. III. Existing Environment o Climate o average precipitation o seasonal o annual Average annual rainfall in the Oroville area is 28.67 inches a year (1957-2007), with the majority of precipitation occurring between November and April. The storm watedleachate basin will be designed to contain all storm runoff that falls on the 25 -acre compost pad over the course of the season; at the same time the basin will provide ample storage to help satisfy the large water demand of the composting operation (materials must be maintained at a minimum of 40% moisture for composting to occur).

STEEBLES LLC, CAROL ANN SEIDENGLANZ LLC; AND STEVEN CONN SEIDENGLANZ LLC FOR CLEAN -CLOSURE OF OROVILLE LANDFILL PROPERTIES CLASS III WOOD WASTE LANDFILL " BUTTE COUNTY The California Regional Water Quality Control Board, Central Valley Region; (hereafter Regional Board) finds that: 1. Oroville Landfill Properties, Oroville Landfill Properties LLC, Jack M. Steebles LLC, Carol Ann Seidenglanz LLC, and Steven Conn Seidenglanz LLC (hereafter Discharger) own a Class III landfill located about three miles south of Oroville, in the southwest'/ of Section' 29 and the southeast'/ of Section 30, T1 9N, R4E, MDB&M,. as shown in Attachment A, which is incorporated herein and made part of this Order. 2. The 105 acre facility consists of three existing unlined waste management units (Unit) covering approximately 27.5 acres, as shown in Attachment B, which is incorporated herein t and made part of this Order. The facility is comprised of Assessor Parcel Numbers(APNs) 078-100-015, 078-100-046, and 078.090-014. APNs 078-100-047 and 035-470-012 were also included as being part of the facility in previous waste discharge requirements. However, the Discharger has shown that no waste disposal activities occurred on the latter two parcels, so they have been removed from the requirements in this Order. ' 3. APNs 078-100-015 and 078-090-014 are owned by Oroville Landfill Properties, Jack M. Steebles LLC, Carol Ann Seidenglanz LLC, and Steven Conn Seidenglanz LLC. APN 078=100-046 is owned -by Oroville. Landfill Properties LLC, Jack M. Steebles LLC; Carol Ann Seidenglanz LLC, and Steven Conn Seidenglanz LLC. 4. On 28 September 1990, the Regional Board issued Order No. 90-266, in which the facility. was,classified as a Class III waste disposal site for the discharge of wood wastes and ash in accordance with the regulations in effect when the Order was issued. Waste Discharge Requirements Order No. R5-2005-0027 was issued on 27 January 2005 and required the. Discharger to close (cap wastes in place) or clean -close (excavate and -remove all residual wastes) the three existing Units. This Order supercedes all previous Orders and allows for clean -closure of the three existing Units. WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2007-0042 -2- OROVILLE LANDFILL PROPERTIES, ET AL. FOR CLEAN -CLOSURE OF OROVILLE LANDFILL PROPERTIES CLASS III WOOD WASTE LANDFILL BUTTE COUNTY 5. Section 21090(f) of Title 27 California Code of Regulations (hereafter Title 27 or 27 CCR) states in part, "The purpose of clean -closure is to render the landfill (including all surrounding environs contaminated by waste released from the landfill) no longer capable of posing a threat to water quality." SITE DESCRIPTION, 6. The landfill is located along the eastern margin of the Sacramento Valley approximately one mile east of the Feather River. The area is characterized by rolling foothills grading eastward into the steeper flanks of the Sierra Nevada Mountains and westward toward the flat expanse of the valley floor. 7. The previous site owner, Louisiana-Pacific Corporation, planted eucalyptus trees and �i spread sawdust from their mill operations" along the south and east sides -of the landfill property on parcel numbers APN 078-100-015, APN 078-100-046, and APN 078-090-014. After initial placement of the sawdust mulch, leachate consisting primarily of tannins and ' lignins was generated from the decomposing wood wastes and had the potential to enter storm water drainage courses. The Discharger constructed Pond 7 in the southeast corner of APN 078-090-014 to capture leachate laden storm water. The Discharger has requested to remove APN 078-090-014 from these waste discharge requirements. However, before ' APN 078-090-014 is removed from the waste discharge requirements, the Discharger will need to demonstrate that residual wastes, which may be present on.the parcel, pose no threat to water quality. 8. Four geologic major eolo is units have been identified beneath the site. The units that have been major identified from the top of the meta -volcanic bedrock to the ground surface are the Ione �. Formation' the Merhten Formation, the Nomlaki Tuff, and the Laguna Formation. With the exception of the volcanic Nomlaki Tuff, the units, are composed of Cenozoic flood deposits from the current and ancestral Feather River System. The Laguna and Merhten ' Formations contain water bearing sands and gravels that are commonly separated by' interbedded clayey aquitards. 9. The closest Holocene fault is the Cleveland Hill Fault located approximately seven miles southeast of the facility. The maximum credible earthquake is estimated to be a ML = 6. The peak horizontal acceleration at the site, considering the maximum credible earthquake, is approximately 0.3g. 10. Land uses within 1,000 feet of the facility are zoned industrial. 11. The climate in the Oroville area is dry with hot summers and mild winters. The facility receives a mean annual rainfall of 29 inches with nearly 90 percent occurring between November and April. The average annual evaporation is approximately 68 inches. ' WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2007-0042 -3- OROVILLE LANDFILL PROPERTIES, ET AL. FOR CLEAN -CLOSURE OF OROVILLE LANDFILL PROPERTIES CLASS III WOOD WASTE LANDFILL BUTTE COUNTY 12. The 100 -year, 24-hour precipitation event is estimated to be 5.51 inches, based on Department of Water Resources' Bulletin No. 195 entitled Rainfall Analysis for Drainage Design Volume 11 Long -Duration Precipitation Frequency Data, dated October 1976. ' 13. The waste management facility is not within a 100 -year flood plain. WASTE AND SITE CLASSIFICATION 14. The Discharger purchased the site in September 2002. The previous owner, Louisiana- Pacific Corporation, discharged wood wastes to Units 1 and 2, and ash from a wood -fired cogeneration facility to Unit 4. Unit 3 was sited, but never received waste. Unit 1 stopped receiving wastes in 1988 and Unit 2 stopped receiving wastes in 2001. 15. Chemical constituents found in the wood waste at the facility that have the potential to affect the quality of waters of the State include pentachlorophenol (PCP), formaldehyde, polynuclear aromatic hydrocarbons (PAHs), tannins, and lignins. Formaldehyde in the waste originated from the Louisiana-Pacific Corporation hardboard facility, which used a urea -formaldehyde glue. PAH compounds encountered in the waste may be from water. flowing.from,the adjacent Koppers wood -treating facility or associated with ash that.was previously disposed in the landfill. Tannins and lignins are normal decomposition products of wood waste. None of the above constituents have been detected in groundwater beneath the site in concentrations that affect beneficial uses. SURFACE AND GROUND WATER CONDITIONS 16. The Water Quality Control Plan for the Sacramento River and San Joaquin River Basins, Fourth Edition (hereafter Basin Plan), designates beneficial uses, establishes water quality objectives, and contains implementation plans and policies for all waters of the Basin. ' 17. Surface drainage is to intermittent drainage courses north and west of the facility, which are tributary to the Feather River in the Lower Feather River Hydrologic Area (515.40) of the Sacramento Hydrologic Basin. The Feather River is located approximately one mile west ' of the site. . 18.The designated beneficial uses of the Feather River, as specified in the Basin Plan, are ' municipal and, agricultural supply, water contact and non -water contact recreation, warm and cold fresh water habitat, warm and cold freshwater fish migration, warm and cold freshwater fish spawning habitat, wildlife habitat, and groundwater recharge. ' 19.The first -encountered groundwater is about 75 to 140 feet below the native ground surface. Groundwater elevations range from 126 feet MSL to 177 feet MSL. 20. Monitoring data indicates background groundwater quality has an electrical conductivity (EC) ranging between 325 and 525 micromhos/cm and a total dissolved solids (TDS) concentration ranging between 163 and .300 mg/I. WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2007-0042 OROVILLE LANDFILL PROPERTIES, ET AL. FOR CLEAN -CLOSURE OF OROVILLE LANDFILL PROPERTIES CLASS III WOOD WASTE LANDFILL BUTTE COUNTY 21.The direction of groundwater flow is toward the southwest. The groundwater gradient measured during first quarter 2004 was 0.01 feet per foot. -4- 22. The designated beneficial uses of the groundwater, as specified in the Basin Plan, are domestic and municipal supply, agricultural supply, industrial service supply, and industrial process supply. SURFACE AND GROUND WATER MONITORING 23. The current groundwater monitoring system includes four monitoring wells, ,LF -1 A, LF -2, LF -4, and LF -5: Three additional monitoring wells (LF -1, LF -3, arid W-2) have previously been included in the groundwater monitoring network. However, these wells are no longer used in the current monitoring system. Monitoring well LF -1 was replaced by monitoring well LF -1A in August 2000 due to an improper screen interval and low groundwater yield. It has been reported that monitoring well LF -3 was abandoned after Unit 1 ceased accepting wastes. Monitoring well W-2 was installed in June 1988 by the United States Environmental Protection Agency as part of the -soil and groundwater investigation at the Koppers Superfund Site located adjacent to the former Louisiana-Pacific Corporation mill. It has been reported that monitoring well W-2 was abandoned after the site investigation was completed, but data demonstrating proper destruction of the well has not been provided. All remaining monitoring wells will be abandoned at the completion of the clean - closure project after the Discharger demonstrates that residual wastes left at the site pose no threat to water quality 24. Monitoring well LF -1A was installed in August 2000 and is located north and hydraulically upgradient of Unit 1. The total depth of well LF -1A is 138 feet with a screen interval between 115 and 135 feet below ground surface (bgs). Monitoring well LF -2 was installed in June 1987 and is located near the southwest corner and hydraulically downgradient of Unit 2. The total depth of well LF -2 is 162 feet with a screen interval between 138 and 158 feet bgs. Monitoring well LF -4 was installed in June 1987 and is located just south and hydraulically down or cross gradient of Unit 1. The total depth of well LF -4 is 160 feet with a screen interval between 129 and 159 feet bgs. Monitoring well LF -5 was installed in June 1987 and is located just south and hydraulically downgradient of Unit 2. The total depth of well LF -5 is 169 feet with a screen interval between 138 and 168 feet bgs. 25. Three unlined storm water detention basins exist at the site. Pond 1 is located at the northwest corner of Unit 1, Pond 5 is located at the western edge of Unit 2, and Pond 7 is located at the southeast corner of the facility. Surface drainage from the site and Units drains toward these three ponds. Once the storm water level in the ponds reaches a specific depth, water discharges off site to surface drainage courses and toward the Feather River. A leachate seep has occasionally appeared at the northwest corner of Unit 1, just above Pond 1. Surface water quality monitoring is required pursuant to this Order and the Surface Water Detection Monitoring Program satisfies the requirements of Title 27. WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2007-0042 -5- OROVILLE LANDFILL PROPERTIES, ET AL. FOR CLEAN -CLOSURE OF OROVILLE LANDFILL PROPERTIES CLASS III WOOD WASTE LANDFILL BUTTE COUNTY 26. Volatile organic compounds (VOCs) are often detected in a release from a landfill. Since volatile organic compounds are not naturally occurring and thus have no background value, they are not amenable to the statistical analysis procedures contained in Title 27 CCR for the determination of a release of wastes from a Unit. 27.Title 27 CCR Sections 20415(e)(8) and (9) provide for the non -statistical evaluation of . monitoring data that will provide the best assurance of the earliest possible detection of a release from a Unit in accordance with Title 27 CCR Section 20415(b)(1)(B)2.4. However, Title 27 CCR does not specify a specific method for non -statistical evaluation of monitoring data. 28. The Regional Board may specify a non -statistical data analysis method pursuant to Title 27 CCR Section 20080(a)(1). Section 13360(a)(1) of the California Water Code allows the Regional Board to specify requirements to protect underground or surface waters from leakage from a solid waste site, which includes a method to provide the best assurance of determining the earliest possible detection of a release. 29. In order to provide the best assurance of the earliest possible detection of a release of non - naturally occurring waste constituents from a Unit, this Order specifies a non -statistical method for the evaluation ofmonitoring data. 30. The specified non -statistical method for evaluation of monitoring data provides two criteria (or triggers) for making the determination that there has been a release of non -naturally occurring waste constituents from a Unit. The presence of two non_naturally occurring waste constituents above their respective method detection limit (MDL), or one non - naturally occurring waste constituent detected above its practical quantitation limit (PQL), indicates that a release of waste from a Unit has occurred. Following an indication of a release, verification testing will be conducted to determine whether there has been a release from the Unit, or there is a source of the detected constituents other than the landfill, or the detection was a false detection. Although the detection of one non -naturally occurring waste constituent above its MDL is sufficient to provide for the earliest possible detection of a release, the detection of two non -naturally occurring waste constituents above the MDL as a trigger is appropriate due to the higher risk of false -positive analytical results and the corresponding increase in sampling and analytical expenses from the use of one non -naturally occurring waste constituent above its MDL as a trigger. FINANCIAL ASSURANCES 31. The Discharger submitted updated Closure and Post -Closure Maintenance Cost Estimates dated 13 July 2006. Costs for closure were estimated to be $1,602,376.00 and costs for 30 years of post -closure maintenance were estimated to be $1,427,218.00. The cost estimates included a Professional Certification for Initial Closure and Post -Closure Maintenance Costs dated 13 July 2006, which was signed and stamped by the Discharger's consultant, a Registered Professional Engineer. The Discharger and the Regional Water Board are currently engaged in negotiations regarding the amount of WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2007-0042 OROVILLE LANDFILL PROPERTIES, ET AL. FOR CLEAN -CLOSURE OF OROVILLE LANDFILL PROPERTIES CLASS III WOOD WASTE LANDFILL BUTTE COUNTY financial assurances described herein. These negotiations may result in the financial assurances being adjusted accordingly. 11s� 32. The Discharger established a Letter of Credit dated 29 September 2006 in the amount of $3,133,494.00 to cover closure and post -closure maintenance costs. 33. The Discharger. submitted an 8 April 2004 cost estimate for initiating and completing corrective action for all known or reasonably foreseeable releases from the landfill. The foreseeable release scenario that was used to develop the cost estimate involves corrective action associated with leachate seeps at the landfill surface and potential assessment of groundwater impacts. The 8 April 2004 corrective action cost estimate is $103,900.00. This estimate has not been increased to reflect inflation factors since its initial development. Additionally, the Discharger has not demonstrated financial assurances for initiating and completing corrective actio_ n in the amount of the approved cost estimate, pursuant to Section 22221 of Title 27. ' 34. Section 22236 of Title 27 requires the Discharger to submit a report by 1 June of each year calculating the increase in the cost estimates for closure and/or post -closure maintenance and/or corrective action due to the inflation factor for the previous calendar year. The Discharger must increase the monetary amount of the financial '.mechanism(s) based upon the inflation factor. LANDFILL CLOSURE 35..This landfill is not yet closed. The current Discharger has never disposed wastes at the site. The last receipt of waste at the site was to Unit 2 during second quarter of 2001. Several leachate seeps at the northwest corner of Unit 1 have been observed during previous wet weather seasons. Low concentrations of pentachlorophenol and formaldehyde were detected in storm water ponds at the site, including Pond 1 located below the leachate seep locations, during 2003 and 2004. 36. In accordance with Title 27 CCR Section 20950(a)(2)(A)(1), the goal of closure Performance Standards includes, but is not limited to, installation of a final cover to minimize water infiltration into the waste, thereby minimizing the production of leachate and gas. 37. In accordance with Title 27 CCR Section 20950(a)(2)(B), the goal of closure Performance Standards.for Units that are clean -closed is to physically remove°all waste and contaminated materials from the Unit and from its underlying and surrounding environs, such that the waste in the Unit no longer poses a threat to water quality. Successful completion of clean -closure eliminates the need for any post -closure maintenance period. 38. The Discharger submitted a revised Report of Waste Discharge (ROWD) for Clean -Closure of the Oroville Landfill. Properties' Class III Wood Waste Landfill dated 20 December 2006. In the_ROWD, the Discharger proposes to excavate wood wastes from Units 1 and 2, WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2007-0042 OROVILLE LANDFILL PROPERTIES, ET AL. FOR CLEAN -CLOSURE OF OROVILLE LANDFILL PROPERTIES CLASS III WOODWASTE LANDFILL BUTTE COUNTY process and separate the wastes from cover soils on-site, and then haul the recovered wood waste to a facility approved by the Executive Officer for re -use or.disposal. The Discharger also proposes to excavate wood -ash from Unit 4 and haul the materials to agricultural lands for use as a soil amendment. -7- 39. This Order allows the Discharger to proceed with clean -closure actions in accordance with. Section 21090(f) of Title 27, the 20 December 2006 revised ROWD, and the requirements of these waste discharge requirements and the attached monitoring and reporting program. CEQA AND OTHER CONSIDERATIONS 40. The action to revise waste discharge requirements for this existing facility is exempt from the provisions of the California Environmental Quality Act (CEQA); Public Resource Code Section 21000, et seq., and the CEQA guidelines, in accordance with Title 14 CCR, Section 15301. 41. This Order implements: a. The Water Quality Control Plan for the Sacramento River and San Joaquin River Basins, Fourth Edition (and subsequent revisions); b. The prescriptive standards and performance goals of Chapters 1 through 7, Subdivision 1, Division 2, Title 27 CCR, effective 18 July 1997, and subsequent revisions; ' . c. The Porter -Cologne Water Quality Control Act (as amended 1 January 2004 and subsequent revisions); and d. State Water Resources Control Board Resolution No. 68-16, Statement of Policy..

' 6. The Water Quality Protection Standard for organic compounds that are not naturally occurring and not detected in background groundwater samples shall be taken as the detection limit of the analytical method used (i.e., US -EPA methods 8260 and 8270). The repeated detection of one or more non -naturally occurring organic compounds in samples above the Water Quality Protection Standard from detection monitoring wells is'evidence of a release from the Unit. ' WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2007-0042 -14- OROVILLE LANDFILL PROPERTIES, ET AL. FOR CLEAN -CLOSURE OF OROVILLE LANDFILL PROPERTIES CLASS III WOOD WASTE LANDFILL BUTTE -COUNTY 7. The concentrations of the constituents of concern in waters passing the Point of Compliance shall not exceed the concentration limits established in the Water Quality Protection Standard Report. 8. For each monitoring event, the Discharger shall determine whether the landfill is in compliance with the Water Quality Protection Standard using procedures specified in Monitoring and Reporting Program No. R5-2007-0042 and Title 27 CCR Section 20415(e). 9. The Discharger shall submit by 15 June 2007 for Executive Officer review and approval a Sample Collection and Analysis Plan. The Sample Collection and Analysis Plan shall at a minimum include: a. Sample collection procedures describing purging techniques, sampling equipment, and decontamination of sampling equipment; b. Sample preservation information and shipment procedures; c. Sample analytical methods and procedures; d: Sample quality assurance/quality control (QA/QC) procedures; and e. Chain of Custody control. 10. For any given monitored medium, the samples taken from all monitoring points and background monitoring points to satisfy the data analysis requirements, for a given reporting period shall all be taken within a span not to exceed 30 days, unless the Executive Officer approves,a longer time period, and shall be taken in a manner that ensures sample independence to the greatest extent feasible. Specific methods of collection and analysis must be identified. Sample collection, storage, and analysis shall be performed according to the most recent version of USEPA Methods, such, as the latest editions, as applicable, of: (1) Methods for the Analysis of Organics in Water and Wastewater (USEPA 600 Series), (2) Test Methods for Evaluating Solid Waste (SW -846, latest edition), and (3) Methods for Chemical. Analysis of Water and, Wastes (USEPA 600/4-79-020), and in accordance with the approved Sample Collection and Analysis Plan. 11. If methods other than USEPA-approved methods or Standard Methods are used, the exact methodology shall be submitted for review and approval by the Executive Officer prior to use. . 12. The methods of analysis and the detection limits used must be appropriate for ' the expected concentrations. The analytical method having the lowest method detection limit (MDL) shall be selected from among those methods, which would provide valid results in light of any matrix effects or interferences. WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2007-0042 -15 OROVILLE LANDFILL PROPERTIES, ET AL. FOR CLEAN-CLOSURE OF OROVILLE LANDFILL PROPERTIES CLASS III WOOD WASTE LANDFILL BUTTE COUNTY 13. "Trace" results - results falling between the MDL and the practical quantitation limit (PQL) - shall be reported as such, and shall be accompanied both by the estimated MDL and PQL values for that analytical run. 14. MDLs and PQLs shall be derived by the laboratory for each analytical procedure, according to State of California laboratory accreditation procedures. These MDLs and PQLs shall reflect the detection and quantitation capabilities of the specific analytical procedure and equipment used by the lab, rather than simply being quoted from USEPA analytical method manuals. In relatively interference -free water, laboratory -derived MDLs and PQLs are expected to closely agree with published USEPA MDLs and PQLs. 15. If the laboratory suspects that, due to a change in matrix or other effects, the true ' detection limit or quantitation limit for a particular analytical run differs significantly from the laboratory -derived MDL/PQL values, the results shall be flagged accordingly, along with -estimates of the detection limit and quantitation limit actually achieved. The MDL shall always be calculated such that it represents the lowest achievable concentration associated with a 99% reliability of a nonzero, result. The PQL shall always be calculated such that it represents the lowest- constituent owestconstituent concentration at which a numerical value can be assigned with reasonable certainty that it represents the constituent's actual concentration in the sample. Normally, PQLs should be set equal to the concentration of the lowest standard used to calibrate the analytical procedure. 16. All QA/QC data shall be reported, along with the sample results to which they apply, ' including the method,, equipment, analytical detection and quantitation limits, the percent recovery, an explanation for any recovery that falls outside the QC limits, the results of equipment' and method blanks, the results of spiked and surrogate samples, the frequency of quality control analysis, and the name of the person(s) ' performing the analyses. Sample results shall be reported unadjusted for blank results or spike recoveries. In cases where contaminants are detected in QA/QC samples (i.e., field, trip, or lab blanks), the accompanying sample results shall be tappropriately flagged. 17. Unknown chromatographic peaks shall be reported, flagged, and tracked for ' potential comparison to subsequent unknown peaks that may be observed in future sampling events. Identification of unknown chromatographic peaks that recur in subsequent sampling events may be required. ' 18. The statistical method shall account for data below the practical quantitation limit (PQL) with one or more statistical procedures that are protective of human health and the environment. Any PQL validated pursuant to Title 27 CCR Section 20415(e)(7) that is used in the statistical method shall be the lowest concentration (or value) that can be reliably achieved within limits of precision and accuracy WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2007-0042 -16- OROVILLE LANDFILL PROPERTIES, ET AL. FOR CLEAN -CLOSURE OF- OROVILLE LANDFILL PROPERTIES CLASS III WOOD WASTE LANDFILL BUTTE COUNTY specified in the WDRs for routine laboratory operating conditions that are available to the facility. The Discharger's technical report, pursuant to Title 27 CCR Section 20415(e)(7), shall consider the PQLs listed in Appendix IX to Chapter 14 of Division 4.5 of Title 22, CCR, for guidance when specifying limits of precision and accuracy. "For any given constituent monitored at a background or downgradient monitoring point, an indication that falls between the MDL and the PQL for that constituent (hereinafter called a "trace" detection) shall be identified and used in appropriate statistical or nonstatistical tests. Nevertheless, for a statistical :method that is compatible with the proportion of censored data (trace and ND indications) in the data set, the Discharger can use the laboratory's concentration estimates in the trace range (if available) for statistical analysis, in order to increase the statistical power by decreasing the number of "ties". 19. Background for water samples shall be represented by the data from all samples taken from applicable background monitoring points during that reporting period (at least one sample from each background monitoring point). 20. The Discharger may propose an alternate statistical method [to the methods listed under Title 27 CCR Section 20415(e)(8)(A-D)] in accordance with Title 27 CCR Section 20415(e)(8)(E), for review and approval by the Executive Officer. Upon receiving written approval from the Executive Officer, alternate statistical procedures may be used for determining the significance of analytical results for common laboratory contaminants (i.e., methylene chloride, acetone, diethylhexyl phthalate; and di-n-octyl phthalate). Nevertheless, analytical results involving detection of these analytes in any background or downgradient sample shall be reported and flagged for easy reference by Regional Board staff. 21. r The Discharger shall use the following non -statistical method for all analytes that are detected in less than 10% of the background samples. The non -statistical method shall be implemented as follows: a. From the constituent of concern or monitoring parameter list, identify each analyte in the current sample that exceeds either its respective MDL or PQL. The Discharger shall conclude -that the exceedance provides a preliminary indication of a release or a change in the nature or extent of the release, at that monitoring point, if either. 1) The data contains two or more analytes that are detected in less than 10% of background samples that equal -or exceed their respective MDLs; or 2) The data contains one or more analyte that equals or exceeds its PQL.

Discrete Retest [Title 27 CCR Section 20415(e)(8)(E)]: 1) In'the event that the Discharger concludes that there is a preliminary indication of a release, then the Discharger shall immediately notify Regional Board staff by phone or e-mail and, within 30 days of such indication, shall collect two new (retest) samples from the monitoring point where the release is preliminarily indicated. 2) For any given retest sample, the Discharger shall include, in the retest analysis, only the laboratory analytical results for those analytes detected in the original sample. As soon as the retest data are available, the Discharger shall conclude that there is measurably significant evidence of a release if two or more analytes equal or exceed their respective MDLs or if one or more analyte equals or exceeds its PQL and shall: a) Immediately notify the Regional Board about any constituent or constituents verified to be present at the monitoring point, and follow up with written notification submitted by certified mail within seven days of validation; and b) Comply with ¶22, below if any constituent or constituents were verified to be present. 3) Any analyte that triggers a discrete retest per this method shall be added to the monitoring parameter list such that it is monitored during each ' regular monitoring event. 22. If the Discharger determines that there is measurably significant evidence of a release from the Unit at any monitoring point, the Discharger shall immediately implement the requirements of Xl.

R5-2007-0042 OROVILLE LANDFILL PROPERTIES, ET AL. FOR CLEAN -CLOSURE OF OROVILLE LANDFILL'PROPERTIES CLASS III WOOD WASTE LANDFILL BUTTE COUNTY ' The Oroville Landfill Properties Class III Wood Waste Landfill is located approximately three milessouth of Oroville. The site is owned by Oroville Landfill Properties, Oroville Landfill Properties LLC, Jack M. Steebles LLC, Carol Ann Seidenglanz LLC, and Steven Conn Seidenglanz LLC (hereafter Oroville Landfill Properties; et al. or Discharger). The site began ' operations in 1.973 under the former ownership of Louisiana-Pacific Corporation. In September 2002, Oroville Landfill Properties et al purchased the site. Three waste management units (Units) exist at the 105 acre facility. Units 1 and 2 were used for disposal of wood waste and Unit 4 was used for disposal of ash from a nearby wood fired cogeneration facility. No wastes have been disposed at the site since 2001. ' Four major geologic units have been identified beneath the site. The units that have been identified from the top of the meta -volcanic bedrock to the ground surface are the lone ' Formation, the Merhten Formation, the Nomlaki Tuff, and the Laguna Formation. With the exception of the volcanic Nomlaki Tuff, the units are composed of Cenozoic flood deposits from the current and ancestral Feather River System. The Laguna and Merhten Formations contain water bearing sands and gravels that are commonly separated by interbedded clayey aquitards. Four monitoring wells make up the groundwater detection monitoring system. First encountered groundwater is. between 75 and 140 feet below the native ground surface. Groundwater flow at the site is generally towards the southwest. . The Discharger proposes to clean -close the landfill and transport recovered materials to locations or facilities approved by the Executive Officer for re -use or disposal. Once the clean- closure project is complete, the Discharger will implement appropriate erosion and sediment control best management practices until the site is stabilized. Two years of post -clean -closure groundwater monitoring is also required after completion of the clean -closure project. The Discharger will no longer be subject to waste discharge requirements or post -closure maintenance after completion of the clean -closure project is approved. This revised. Order allows for clean -closure of the Oroville Landfill Properties Class III Wood Waste Landfill. DPS: sae 5/14/2007 ORDER NO.

The exception in subsection (b) of GC 66474.2 would allow the county to apply new standards (such as GP 2030 and the new Zoning .Ordinance) which are in effect at the approval/disapproval stage if the county has done all of the following: 1) Initiated proceedings, byway of ordinance, resolution, or, motion; to enact the new standards; 1 It is beyond the scope of this memo to discuss the, differences between "regular" and "vesting" tentative maps at different stages of the process. 04 2) Published notice in the manner prescribed in GC 65094; and 3) Enacted the new standards as a result of the initiated proceedings. In our opinion; the county has not yet completed the steps necessary for the exception in subsection (b) to apply. Although proceedings have been initiated by adoption of Resolution 06- 085, notice has not yet been published in the manner prescribed in GC 65094. The required notice must be published at least once in a newspaper of general circulation in the. county, the publication must be at least 10 days prior to the hearing, and the notice must: 1) state the date, time and place of the public hearing; 2) identify the hearing body; 3) contain a general explanation of the matter to be considered, including a description sufficient to notify the public of the nature of the proposed new standards; and 4) give a general description of the location of the property that is the subject of the hearing. Draft notice We are attaching a draft hearing notice which we believe would meet the above requirements. We recommend that a notice in substantially this form be published as soon as possible, and perhaps a second time closer to the hearing date, and that all map applicants thereafter be provided a copy of it. If such a notice is published and GP 2030 is enacted and in effect when. a map reaches the approval/disapproval stage, the new standards it contains will apply if the map application was determined to be, complete on a date following the publication. You may wish to insert additional information into the notice or to tailor it. Please furnish us a copy of your revised draft notice before submitting it for publication so that we may assist in it in final form. Grounds for disapproval Even if the notice is published, the "old" general plan and zoning will still apply to: 1) map applications determined to be complete before the publication; and 2) all other applications reaching the approval/disapproval stage before GP 2030 and the new Zoning Ordinance are enacted and become effective. The fact that such applications are not consistent with GP 2030 and/or the new Zoning Ordinance would not constitute grounds for disapproval. However, other grounds for disapproval, as set forth in GC 66474, 66474.4, 66474.6, 66474.61, 66474.63, and Butte County Code sections 20-65, 20-65.5, 20-100, and 20-101 may apply. In addition, an application could be disapproved pursuant to CEQA if the map would have a significant adverse effect on the environment and that impact cannot feasibly be mitigated to a level of insignificance. Interim zoning If concerns remain that map applications in conflict with GP 2030 and the new Zoning Ordinance may reach the approval/disapproval stage at a time or under circumstances which would not allow disapproval for any of the above reasons, consideration might be given to the adoption of interim zoning pursuant to GC 65858. Interim -zoning could be effective. in areas where there is development pressure and where "down -zoning" is contemplated to be a part of the GP 2030 and new Zoning Ordinance process. Interim zoning requires a-4/5 vote of the Board of Supervisors, can. be adopted effective immediately, and can be extended to remain in effect for a total of up to two years. Please advise if we may be of assistance in preparing an appropriate . interim. zoning .ordinance.

The purpose of this letter is to provide additional information on the proposed siting of a compost facility (Oroville Gold) off -of Ophir Road in Oroville, on land owned by Oroville Landfill Properties, LLC. The subject project location is'due east of Highway 70. The project area is triangular in shape and is bordered by Ophir Road to the south; the Union Pacific railway line to the west; and the abandoned Southern Pacific railway right of way to the east (Figure 1). Oroville Gold LLC will be an organic composting .facility located on property permitted under the current M-2 zoning for use as a Class III wood waste landfill. The landfill was previously owned and operated by Louisiana. Pacific Corp (LP). LP developed three active Waste Management Units (WMU) on the subject property. The proposed project facilities will occupy approximately 63.3 acres, most of which are currently included in the Class III wood waste landfill .waste discharge requirements (WDR). The proposed composting facility operations (office, storage, processing and active composting) include Assessor's Parcel Numbers (APNs) 078-100-015, 078-100-046, 078-100-047, 078-090-014, and 035-470-012. For the purposes of this letter we will use the APN numbers to identify the property, since the existing WDR was issued using those descriptions. The existing WDRs include the property identified as APNs 078-100-015 & -046, and 078- 090-014 (Figure 2). What are identified as APNs 078-100-047 & 035-470-12 on Figure 2 (attached) were removed from the WDR by the Water Quality Control Board (WQCB) on May 0, 2007 when they issued their most recent Order (R5-2007-0042), which permits the clean closure operations for the landfill. The portions of the property where the new compost facility will be located have never been used as WMUs. . In a letter dated November'19, 2008, the WQCB outlined the requirements for removal of additional portions of the subject property from the WDR (Figure 2; APNs 078-100-015 & - 046, and 078-090-014). A composting facility cannot be permitted on land permitted for WMUs. In order to separate the area proposed for the composting facility, the WQCB ' required that Oroville Gold, "work with the local land use agencies regarding splitting parcels to separate landfill area land from the area east of the landfill central access road." The new Ms. Jolliffe March 17, 2009 Page 2 of 4 compost facility will be sited on the land that either has already been, or will be, removed from the WDR. As agreed at the recent meeting, the area to be removed from the WDR will be surveyed so that a County -approved legal description can be developed and provided to the WQCB to accommodate the permitting -requirements. All of the subject parcels are currently zoned M-2 (Heavy Industrial). The activities and operational processes undertaken by a compost facility have similar or less impact on the surrounding neighborhood then the'industrial operations provided for in an area zoned for heavy industrial use. As the attached zoning map (Figure 3) shows, the boundary of the compost facility will be at least 800 feet from commercially -zoned districts. The distance to any existing residential areas is even greater. The responsible development of any industrial project involves consideration of potential impacts to neighbors and the immediate environment. Hence, in the case of a compost facility, the most crucial consideration is the distance between the facility and residential areas. In the case of Oroville Gold, there is a minimum distance of 2,000 feet from the proposed composting area to the closest residential areas, and one mile to the nearest school. ' In other words, the. immediate environs are entirely industrial. The discretionary option of requiring a Use Permit (allowed for by section c(5) of 24-180 M-2 (Heavy Industrial) Zone, Butte County General Ordinance) is intended primarily to address possible impacts where the proposed use will be located less than 100 feet from the boundary of a zone that allows residential uses. Through the use of Pathogen Reduction Windrows, Aerated Static Piles and other composting techniques, organic waste material will be recycled into premium quality compost. The. existing permitted uses on the property clearly and adequately cover the proposed composting activity. Operations at the site will be compatible with the heavy industrial zoning of the surrounding property. Many of the enumerated permitted uses in a heavy industrial zone have significant potential impacts on the surrounding environment; for example, breweries and distilleries, concrete batch plants, metal fabrication, fuel yards and agricultural processing plants are all allowed in the M-2 zone.. Additionally, the.composting of waste material is clearly pertinent to the existing permitted use of landfilling waste on the .property and therefore may also be considered an Accessory Use under the County's Zoning Ordinance, Article III, 24-180 (b)(3). Commercial composting has many synergies with landfill operations; indeed; the two processes are frequently carried out in tandem with many waste management companies'also operating as composters. The likely impacts of the operation are not significantly different from the impacts of a landfill operation: odor mitigation and traffic volumes along with leachate and stormwater collection will all continue to be the focus of the primary management and operational controls and are discussed in more detail below. Ms. Jolliffe ' March 17, 2009 Page 3 of 4 - � / Y i f The process of recycling organic waste inevitably involves the generation of odor. An important key to a successful composting operation is its ability to control and minimize odor _ ` impacts for its local community'. Though initially problematic in the early years'of large-scale lcomposting, the industry has developed many successful odor controls•over recent years. In Particular, the composter must manage moisture to prevent anaerobic conditions, and 1 appropriately cover odiferous materials. Additional measures such as biolfilters, aeration of ' leachate ponds and the use of misting systems are also reliable and proven methods of preventing odor. Y . • , ' Individual facilities need unique solutions, which depend on the particular conditions ' encountered. An essential element of success is the participation and guidance of both local and state regulators through the use and development of such operational documents as the �. • Odor Impact Minimization Plan and Report of Composting Site Information. Copies of the draft operational documents are attached and we look forward to cooperating'closely with the Local Enforcement Agency to develop existing and new mitigations as necessary. . The potential of the facility to generate both traffic and noise is also a consideration. Thee, a need to haul materials to and from the site will generate truck traffic, and there will be' a small number of car trips generated by employees arriving -and leaving work. However, this will not differ greatly from the traffic previously generated when the landfill was open or anticipated when the environmental review was completed for the area allowing M-2 (Heavy Industrial) zoning.. Likewise, the use of operational equipment will create some increase in ' noise above the current ambient level. Again though, an area zoned 'for heavy industry includes entitlements for precisely this purpose, i.e. to facilitate the operation of industrial equipment. The relative low level of noise at the current time is not reflective of a fully-, utilized industrial area. In short.'a composting operation does not present any.special or greater risk to, the environment than the existing M-2 entitlements permit. The addition of an organic compost facility will have enormous benefits for the local community, both economically and environmentally. The quantity,of waste that can be recycled and, most importantly, diverted away from landfills is limited only by the facility's ' operational capacity to process it. California's legislature has set high targets in its drive to reduce reliance on landfills. Local compost facilities in other California counties have been highly successful in helping local government achieve the waste diversion standards t mandated by the State. Local businesses that. are faced with increase regulations regarding how to manage their waste appropriately will have a viable option to recycle via composting available as early as this harvest and processing season. Oroville Gold will provide a quicker and less expensive option that does not involve the capital,expense.of infrastructure improvements at a time when many businesses are under considerable financial pressure. - 'The compost produced will. be a high-quality soil, amendment that repairs and replenishes nutrient losses in the native soil. This will greatly assist the agricultural growers in this area. . ' �� r ; Ms. Jolliffe March 17, 2009 Page 4 of 4 Its local availability will reduce transportation costs, benefiting both growers and the environment. Furthermore, development of the facility will create new job opportunities (facility employees, trucking and associated services). Finally, the recycling of landfill wood waste is both effective and environmentally productive as a means of assisting with the clean closure of the closed LP site. . I trust this is the information you require at. this time. Please do not hesitate to contact me if you would like any more details or if I can be of any further assistance.
