1.0 INTRODUCTION The existing Water Pollution Control Facility (WPCF) Permit expired on November 31,2010. The Department received renewal application number 971073 from Heard Farms Inc., on September 11, 2009. As this renewal application was submitted to the Department in a timely manner prior to the expiration date of the permit, the permit must not be deemed to expire until final action has been taken on the renewal application to issue the new permit as per OAR 340-045-0040.

This permit evaluation report describes the basis and methodology used in developing the permit. The permit is divided into several sections:

Schedule A - Waste discharge limitations Schedule B - Minimum monitoring and report requirements Schedule D - Special conditions Schedule F - General conditions

2.0 FACILITY DESCRIPTION 2.1 General This facility was issued a Land Use Compatibility Statement from Douglas County on August 9,1996. The facility is located approximately five miles north of the City of Roseburg along the West Side of Interstate 5. Access to this facility is on Rogers Road, the facility location is at 578 Rogers Road. This treatment system was designed to treat wastewater, which includes domestic septage, municipal and domestic sludge and grease trap wastes. This permit authorizes the reuse of: 1. Treated Class C and/or Class D recycled water to approved land irrigation sites at approved hydraulic and agronomic rates and, 2. Land application of Class B biosolids approved agronomic rates. Heard Evaluation Report December 12, 2011 File Number 109363 Page 4

Figure 1: Arrow points to the Heard Farms Inc. Wastewater Facility Location at 578 Rogers Rd., Wilbur, OR just west of freeway 1-5.

2.2 Wastewater Treatment Description of Wastewater Treatment Facility and Land Application Practices: The facility is a two-cell lagoon comprised of a primary anaerobic digestion cell (dimensions are 250'xl00'xl6', liquid capacity 912,000 gallons). The second cell is a storage digestion lagoon (dimensions are 250'x500'xl6.5', liquid capacity 8,703,214 gallons).

2.3 Changes in Operation In 2010 the facility recently upgraded their wastewater facility from a pirmary aerated and secondary polishing lagoon system to a covered anaerobic lagoon system with the primary cell used for digestion and the secondaiy cell is used for additional digestion, storage and polishing. The primary and secondaiy cells covered with a High- Density Polyethylene (HDPE) liner to collect methane gas and for odor control.

In 2009 CH2MHU1 did a methane gas product feasibility study based on assumed volatile solids destruction rates and found that there was a potential for the Heard Farms Inc., facility to produce a significant volume of methane gas. The results of the study suggest gas production can have a high correlation to degradable chemical oxygen demand (COD) (90%+ conversion) given minimal seasonal and operational variations. It was estimated that this facility will produce about 16,000,000 cubic feet of methane per year or about 1,400,000 kWh of energy. The Heard Evaluation Report December 12,2011 File Number 109363 Page 5 facility's methane gas produced end use has yet to be determined, but onsite power generation and flaringof f of the gas are most likely to occur for the first couple of years of plant operation.

Anaerobic digestion of organic compounds is achieved by microorganisms, typically known as acid formers and methane formers. This digestion is a two step process where the firstgrou p hydrolyzes and ferments long chain organics into simple organic acids, the second group consumes these organic acids, converts them to methane and carbon dioxide. Several digestion parameters are important in maintaining an environment conducive for methane gas production: anaerobic environment should be devoid of free oxygen; the optimum temperature ranges are the mesophilic 30 to 38C (85 to 100 F) and thermophilic 49 to 57C (120 to 135F); pH range should be 6.6 to 7.6; with sufficient alkalinity of 1000 to 5000 mg/L to maintain the process pH. For biosolid stability the Vector Attraction Reduction (VAR) is achieved by volatile solids reduction of 3 8% or more or equivalent process under the 40 CFR part 503s. Pathogen Reduction must also be shown at or before the VAR process and typically can be achieved by treating the sludge in the absence of free oxygen for a mean cell residence between 15 days at 35 to 55 degrees Celsius and 60 days at 20 degree Celsius. The measurement of fecal coliform as indicators of pathogens is used as showing compliance with Class B biosolid provided at least seven discrete representative samples are taken at the time of land application and that the geometric mean of these samples is less than 2,000,000 organisms MPN per gram of biosolids (diy weight basis).

2.4 Groundwater Issues This facility currently has a Groundwater Monitoring Plan which is part of this permit. There is an ongoing groundwater evaluation of the permittee lagoons (HDPE liner over sand layer with sump-pump over a clay liner) and the leachate detection under drain system. The permittee has collected groundwater data for the last ten years using three monitoring wells around these lagoons. There are several conditions in Schedule D of the current permit that require the facility to follow their existing groundwater monitoring plan (Attachment 1). The existing groundwater monitoring plan is under review and will be updated as needed during the next permit cycle.

Schedule A of the proposed permit prohibits adverse impacts to groundwater,

The biosolids application and recycled wastewater reuse practice should not have a potential for impacting groundwaters of the State when conducted in accordance with the approved plans. Irrigation is scheduled using soil moisture contents at the irrigated site.

No sewage is allowed to discharge directly to public waters. The nearest river which would receive wastewater if it were to discharge is Sutherlin Creek. The creek is more than 1,000 feet south of the nearest effluent reuse site system.

2.5 Storm Water Stormwater is not addressed in this permit. General NPDES permits for stormwater are not required for facilities with a design flow of less than 1 MGD.

2.6 Outfalls 001 Seasonal beneficial land application of Class C recycle water on pastures. 002 Seasonal beneficial land application of Class B biosolids on pastures.

2.7 Biosolids Heard Evaluation Report December 12,2011 File Number 109363 Page 6

Biosolids land application and Recycled Wastewater Reuse: Biosolids generated at this facility must meet at least the criteria for Class B biosolids as prescribed under OAR 340-050 and the EPA's 40 CFR part 503's regulations. The recycled wastewater quality must meet at minimum Class C (Chlorine disinfection) effluent criteria as called out under Oregon Administrative Rule (OAR) 340-055. The land irrigation of recycled wastewater and biosolids land application must meet the guidelines specified in the Biosolid and Recycled Water Use plans, the respective site authorization letters and applicable State of Oregon and federal biosolids rules. The conditions of each site authorization letter are site specific for each land application site Land application sites Attachment 2).

Site Authorization Letters: All DEQ authorized biosolids land application sites require the current property owner's approval for land application for the land application property; the current property owner must be listed on the current DEQ site authorization letter. All existing and new biosolid site authorizations are good until: the property ownership changes, the farming management/practices change such that there is significant non­ compliance with the biosolid site authorization, the biosolid rules and/or your biosolids management plan, and/or the current property owner requests the city to discontinue the land application of biosolids on this site. Site authorizations are for biosolids land application on properties referenced in the authorization. Site authorizations do not convey any property rights or any sort, or any exclusive privileges, or authorized any injury to persons or property or invasion of any other property rights, or any infringement of federal, state or local laws or regulations. Site authorization is subject to criteria detailed in the Oregon Administrative Rules, Chapter 340, Division 50.

There are three approved land application sites of approximately 130 acres on Heard Farms in Wilbur Oregon; these fieldsar e for summer biosolids land application. It is estimated that this treatment facility could produce 375 diy tons of biosolids when the facility is operating at full capacity. At this time approximately 100 acres (100 lb N/acres loading rate) will be needed annually for the biosolids land application process.

Land application of biosolids is approved to take place during the months of June 1 through October 31. The seasonal restriction is based on the annual rainfall of approximately 33 inches in this area, the moderate sloping topography, and the moderately mud stone over silty clay loam/sandstone parent. The permittee can request to irrigate or land apply biosolids during earlier or later parts of the year if weather and soil conditions are favorable. Mr. Heard owns three of the four the land application sites.

Site authorization letters are an addendum to the reuse and management plans, and the WPCF permit. Actual loading rates are site specific and will be found in the site authorization letters along with other best management practices that pertain to each site.

Recycled Water Reuse: Currently, three sites are approved for summer (May 1 through October 1) Class C recycled water application on approximately 79 acres. The Heard Farm land application sites are contiguous with the Heard Farm sewage facility. The soil maps for the general area indicate that soils on the Heard Farm Ranch are moderately deep with slopes of twelve percent or less which could be approved for wastewater reuse and biosolids land application. Mr. Heard owns all of his recycle water use land application sites. Heard Evaluation Report December 12,2011 File Number 109363 Page 7

This facility generates approximately 9,500,000 gallons (27.6-acre feet) of recycled wastewater annually. The estimated nitrogen content is believed to be around 875 lb N per year. Under the Oregon Crop Water Use and Irrigation Requirement; (Bulletin 8530) the highest evapotranspiration (ET) rate for the summer irrigation season is 32.3 inches, and the total irrigation water needed would be about 1.5 acre/feet per acre. Under the Oregon State University Fertilizer Guide the recommended agronomic loading rate for pasture grass is 100 pounds plant available nitrogen/acre, but can be more if several cuttings occur in a growing season. The land irrigation process for this facility will require a minimum 7.2 acres for recycled wastewater reuse.

Management Plans: The existing Biosolids Management (BMP) and Recycled Water Use Plans (RWUP) conform to the regulations (OAR 340-50 and OAR 340-55, respectively) governing treatment, transport and land application of biosolids and recycled wastewater. The RWUP (Attachment 3) and BMP (Attachment 4) were submitted to the DEQ, reviewed, went on public notice with the WPCF permit (1996-1997), and were approved by the Department. An Odor Management Plan (Attachment 5) was also submitted and approved by the Department during the last permit cycle. This plan covers all wastes received, treated and land beneficially applied at this facility and land application sites. Solids and liquids must be managed in accordance with the odor management plan approved by the Department. If acceptance of the grease trap wastes cause an increase in generated odors as determined by the Department, the must notify the permittee in writing that further acceptance of grease trap wastes are prohibited. These plans are part of this permit as is, but these plans still need to be updated so that they reflect the facility upgrade to a covered anaerobic treatment system; therefore, these plans will be renewed during the next permit cycle under another public notice.

3.0 PERMIT HISTORY 3.1 Compliance history This facility has been in operation since 1997. Previously Heard Farms Inc. has received enforcement actions from the water quality program: NON #WWR~1999-027 for exceeding reclaimed water total coliform limit and wind speed limitation; NON #WRR-2000-009 for receipt of unauthorized municipal solids; WL #WRR-2005- 0010 for using reclaimed water not in accordance to reclaimed water use plan; WL #WRR-2007-0018 issued for missed fecal coliform test; February 10, 2009 WL (HeardFWRE090004Iss090210) for facility operating conditions (odors) and uncontrolled land application of biosolids, and May 26,2009 Pre Enforcement Notice (HeardFWRE090024Iss090526) for facility operating conditions (odors) and improper handling of biosolids.

This facility was last inspected on Oct 6,2008 by Gene Wong and Paul Kennedy from the Eugene DEQ, again on December 1,2008 by Paul Kennedy, and On April 2,2009 by Tim Fetridge and Paul Kennedy. The lagoon system was found to be in poor operating conditions; the primary lagoon was overloaded with solids and the secondary lagoon water cap was drawn down too far to prevent odors. The lagoons in the past year have had several problems with odors. This is in part due to the operation of this facility and also overloading this facility with organics. An inspection Warning Letter was sent out for the poor land application practices and lack of operation and maintenance on the chlorine system. Ms. Holly DeRamus with Linn Benton also attended the facility WPCF Inspection on January 22,2009 and she provided comments and offered technical assistance to the permittee on the operation and maintenance of these lagoons.

4.0 PERMIT LIMITATIONS a. Recycle Water Treatment and Land Application The permittee must treat all recycled water, prior to land irrigation to at least Class C treatment as defined in OAR 340-55 to reduce Total Coliform to 240 organisms/100 mL in two consecutive samples, and a seven-day median of 23 organisms/100 ml. All recycled water must be irrigated in accordance with a Department approved RWUP and no discharge to state waters is permitted. Permittee can also land apply Class D recycled water as defined Heard Evaluation Report December 12,2011 File Number 109363 Page 10

in OAR 340-55. All recycled water must be land applied within consumptive and agronomic needs of the crop grown on the approved site.

b. Biosolid Treatment and Land Application

Prior to land application all biosolids must satisfy the Class B biosolids criteria under the Oregon Administrative Rules, Chapter 340, Division 50 biosolid rules, the BMP and the permit conditions. In addition, solids removed from the secondaiy lined lagoon for beneficial use must be stabilized in accordance with the approved vector attraction reduction options outlined the BMP and Oregon Administrative Rules, Chapter 340, Division 50, ("Land Application and Disposal of Sewage Treatment Plant Biosolids and Biosolid Derived Products Including Septage") prior to land application.

For Class B biosolid the sludge must meet the following requirements to be classified Class B with respect to pathogens: take seven discrete representative samples of the sewage sludge that is used or disposed must be collected. Calculate the geometric mean of the density of fecal coliform in the samples collected and this geometric mean must be less than either 2,000,000 Most Probable Number per gram of total solids (diy weight basis) or 2,000,000 Colony Forming Units per gram of total solids (dry weight basis).

VAR requirements for this facility will typically be met by one of the following options when bulk sewage sludge is applied to agricultural land, forest, a public contact site, or a reclamation site. (i) The mass of volatile solids in the sewage sludge must be reduced by a minimum of 38 percent (see calculation procedures in "Environmental Regulations and Technology—Control of Pathogens and Vector Attraction in Sewage Sludge", EPA-625/R-92/013, 1992, U.S. Environmental Protection Agency, Cincinnati, Ohio 45268). (ii) When the 38 percent volatile solids reduction requirement in §503.33(b)(1) cannot be met for an anaerobically digested sewage sludge, vector attraction reduction can be demonstrated by digesting a portion of the previously digested sewage sludge anaerobically in the laboratory in a bench-scale unit for 40 additional days at a temperature between 30 and 37 degrees Celsius. When at the end of the 40 days, the volatile solids in the sewage sludge at the beginning of that period is reduced by less than 17 percent, vector attraction reduction is achieved. (iii) Sewage sludge applied to the land surface or placed on an active sewage sludge unit must be incorporated into the soil within six hours after application to or placement on the land, unless otherwise specified by the permitting authority.

All Department authorized biosolids land application sites require the current property owner's approval for land application and such the current property owner must be listed on the current DEQ site authorization letter. All existing and new biosolid site authorizations are good until: the property ownership changes, the farming management/practices change such that there is significant non-compliance with the biosolid site authorization, the biosolid rules and/or your biosolids management plan, and/or the current property owner requests the city to discontinue the land application of biosolids on this site.

5.0 PERMIT DRAFT DISCUSSION The existing effluent limitations in this WPCF permits are technology based effluent limits. Technology based effluent limits were established to require a minimum level of treatment for industrial or municipal sources using Heard Evaluation Report December 12,2011 File Number 109363 Page 11 available technology. Effluent limits are designed to be protective of the beneficial uses of the land and groundwater.

6.3 Schedule B - Minimum Monitoring and Reporting Requirements Schedule B describes the minimum monitoring and reporting necessary to demonstrate compliance with the conditions of this permit. The authority to require periodic reporting by permittees is included in ORS 468.065(5). Self-monitoring requirements are the primary means of ensuring that permit limitations are being met. However, other parameters need to be monitored to collect information when insufficient information exists to establish a limit, but where there is a potential for a beneficial water quality and solids reuse concerns.

The proposed permit requires keeping a log of volatile solids reduction at the facility. On an annual basis the permittee is to submit a summary of volatile solids to the Department by the 15* of February of each year, for the previous calendar year. This annual summary report should detail the quantity (monthly and yearly totals) of volatile solids reduction from the inlet to the outlet of the facility. The permittee is also required to report then* application rates of Class B biosolid and Class C recycled water. The annual report should also include the total yearly liquid and solids for the facility.

The proposed permit includes a re-opener clause allowing the Department to reopen and modify the permit to include new limitations and/or conditions if changes occur at the facility, which necessitates a modification.

Permittee must perform the minimum monitoring and recordkeeping for recycled wastewater irrigation and biosolids land application as prescribed in: OAR 340-55, OAR 340-50, Schedule B of the WPCF permit, approved management plans and site authorization letters.

RE: WQ-S-Douglas County Reclaimed Water Reuse Land Application Rose Creek Ranch, Bill Svea Property 578 Rogers Road (County Road No. 145) Twp. 26S, R.5W, Sec.6

This letter represents an approval of your request to land apply Reclaimed Water (effluent) to the above referenced property. Approval is subject to criteria detailed in the Oregon Administrative Rules, Chapter 340, Division 55 and the following conditions:

Responsibility: It is the responsibility of Heard Farms, Inc. to ensure the proper handling and application of all Reclaimed Water generated. Transportation of the Reclaimed Water to the application site shall be done in such a manner as to prevent leaking or spilling of the Reclaimed Water onto the highways, streets, roads, waterways or other land surfaces not approved for Reclaimed Water application.

Site Description: The referenced Rose Creek Ranch (Svea property) site is approximately 45 acres (back pastures) of a larger approximately 80 acre parcel which is used as pasture and hay fields. The site is comprised of upland sedimentaiy soils. This land application site is located just north of the Heard Septage Treatment Facility, across Rogers Road in Wilbur, Oregon. Heard Evaluation Report December 12,2011 File Number 109363 Page 24

Level II Reclaimed Water Reuse Land Application Criteria: (SUMMER Application Only from May 1 through Oct. 1)

1. The site (map enclosed) is approved for Reclaimed Water Reuse application during the summer months. Reclaimed Water may be applied at periods during the summer when the soil available water content is between field capacity and permanent wilting point. Field irrigation shall be monitored with in situ moisture sensors (nested soil tensiometers 6-in., 12-in. 18-in., or indirect plant moisture/electric resistance blocks or an equivalent). Soil can be irrigated when approximately 50% of the plant available water (-1/3 to -1 bar) in the root zone (6 to 24 inches) is used. At least three piezometers should be installed to depths of 5 feet at the toe slope of each irrigation site (map of piezometer location is enclosed). Enclosed also is a diagram of a piezometer which consists of 3-4" perforated PVC pipe surrounded by coarse pea gravel with a bentonite collar and a white PVC cap. Irrigation site piezometers (depth of water) shall be read and recorded on a daily log at the start of each irrigation day. If the permittee has a desire to irrigate late spring or early fall, the permittee must submit a written request for written Department approval to irrigate. Approval would be contingent on the weather forecast and pasture soil moisture levels.

2. Level II or higher quality Reclaimed Water shall be applied evenly and in a manner to prevent ponding or site runoff.

3. The surface application of Reclaimed Water shall not be applied closer than 70 feet to any drainage ditch, channel, pond or waterway or within 200 feet of a domestic water source or well. The spray buffer from public roads, neighboring property and horse riding trails is 70 feet. Irrigation over- spray shall be monitored during windy days to assure the 70-foot buffer is not violated. When wind velocities exceed 8 knots (10.4 mph), irrigation should stop to prevent over spray on neighboring properties and horseback riders.

4. Reclaimed Water application rate should not exceed approximately 100 #N/acre/year for pasture grass. Changes in Reclaimed Water Reuse characteristics, crops management and Reclaimed Water Reuse treatment may require change in the Reclaimed Water Reuse application rate in order to maintain proper agronomic nitrogen or plant water consumptive loading rates.

5. If other sources of nitrogen are used, the Reclaimed Water Reuse application rate must be reduced so that commercial nitrogen in combination with Reclaimed Water Reuse nitrogen does not exceed agronomic loading rate on this site (100 N lb./acre-year). This loading rate may be amended if multiple hay cutting occur in a growing season. You must submit a written request justifying an increased Nitrogen loading over the 100 #N/acre-year loading rate.

6. There is a minimum 3-day drying period between the last day the site is irrigated and when the site can be harvested for hay. Heard Evaluation Report December 12,2011 File Number 109363 Page 25

7. The perimeter of the Reclaimed Water Reuse site shall be signed and public access shall be controlled as required under OAR 340-55-015 Table 1. The posted signs shall read as follows "ATTENTION: RECLAIMED WATER USED FOR IRRIGATION-DO NOT DRINK. ATENCION: RECLAMADO DESPERDICIO DE AGUA USADO PARA LA IRRIGACION. NO BEBA EL AGUA". These signs should be posted all along the fenced irrigated pasture at a maximum distance 300 feet between signs.

8. Grazing animals shall not be allowed on the irrigated pasture during Reclaimed Water application.

RE: WQ-S-Douglas County Biosolids Management Plan File Number 109363 Heard Farm Septage Treatment Lagoons Rogers Road (County Road No. 145) Twp.26S,R5W,Sec.6

Mr. Heard: This response is to your May 11, 2001; request to beneficially reuse stabilized septage sludge (Class B Biosolids) on Department authorized land application sites. On October 16, 1997, a Public Hearing was held regarding your Septage Lagoon Facility Water Pollution Control Facility (WPCF) permit (File Number 109363). Under the "WHAT IS PROPOSED" section of the Notice of Public Hearing, this WPCF permit would cover the land application of reclaimed water and biosolids generated from this facility.

The first couple of years operation of your facility did not generate enough biosolid to feasibly dredge and land apply biosolids. This year (2001) you estimate you have accrued enough biosolid (biosolid sample data available to calculate nutrient loading) to make land application feasible.

Responsibility: It is the responsibility of Heard Farms, Inc., to insure the proper treatment, handling, and application of all biosolids generated.

This is an approval of your Biosolid Management Plan (attachment A) which is subject to 1) Management Plan and site authorization letter(s), 2) criteria detailed in the Oregon Administrative Rules, Chapter 340, Division 50, and the 3) the EPA 40 CFR Part 503s.

If you have question concerning this approval please call me at 440-3338.

Sincerely,

Paul Kennedy Natural Resource Specialist Cc: Mark Cullington, Biosolid, DEQ-Portland Heard Evaluation Report December 12,2011 File Number 109363 Page 27

Attachment A Heard Farm Inc., Biosolid Management Plan Introduction: The Heard Farm Inc. owns and operates a domestic septage collection and treatment system under Water Pollution Control Facility (WPCF) permit number 101512. Wastewater processed by the treatment works is principally of domestic origin. No industrial septage is approved to be accepted at this wastewater treatment facility at this time. Treated reclaimed water and biosolids from the treatment plant are beneficially land applied on neighboring farm land in Douglas County, Oregon.

Wastewater Processing: Heard Farm Inc. operates a two- (2) cell septage Treatment Lagoon Facility. The treatment facility consists of pre-screening station, primary digestion lagoon, and a secondaiy polishing-storage lagoon.

Treated effluent from the polishing lagoon is ran through a chlorine system and flash mixer prior to being discharged as reclaimed water for land irrigation.

Solids Storage Structure: The operating capacities of each lagoon in facility are as follows: the primary lagoon is 912,000 gallons (gal), the secondaiy lagoon is 8,700,000 gal. and the chlorine contact chamber is 14,000 gal.

To meet the Class B biosolid and pathogen reduction requirements the lagoon system must show fecal coliform levels meet the 2,000,000 MPN or less per dry gram weight total solids. The permittee can meet Class B pathogen reduction requirement by meeting an alternative process under Process to Significantly Reduce Pathogens (PSRP).

If Heard Farm's facility is not capable of meeting the Class B biosolid pathogen reduction criteria the EPA's 40 CFR parts 503 and the DEQ's OAR 340-50 allow for an approved alternative equivalent treatment method for achieving the Class B biosolid status. Typically the alternative method would be a twenty-four (24) liming process where the digester solids are batch stabilize to a pH of 12 or higher (active mix) for a minimum of two (2) hours.

Under EPA 40 CFR Part 503.33 (b)(2), vector attraction reduction can be demonstrated by achieving a volatile solids reduction of 38 % of total solids in the digester (typically). There are alternative volatile solid reduction methods that are deemed equivalent to the 38% volatile solids reduction such as, alkaline stabilization*, anaerobic bench scale test**, soil incorporation or soil injection.

* Alternative method would be a twenty-four (24) liming process where the solids are batch stabilize to a pH of 12 or higher (active mix) for a minimum of two (2) hours and maintaining the pH at 11.5 or higher for the next 22,5 hr. Heard Evaluation Report December 12,2011 File Number 109363 Page 28

**Digesting a portion of the previously digested sewage sludge anaerobically in the laboratory in a bench-scale unit for 40 additional days at a temperature between 30 and 37 degrees Celsius. When at the end of the 40 days, the volatile solids in the sewage sludge at the beginning of that period is reduced by less than 17 percent, vector attraction is achieved.

Solids Processing: The Heard Farm's treatment works utilizes an anaerobic lagoon process. Typically the lagoon sludge under goes a minimum 4 to 6 months of digestion at ambient temperatures. Prior to removal a representative sample must be tested by performing a volatile solids reduction test or alternative allowed under Oregon Administrative Rules (OAR) 340 Div. 50 and EPA 40 CFR Part 503.

Permittee shall signed Class B biosolid certification statements, for pathogen and vector attraction reduction and land application (enclosed attachment 1). These statements and a current biosolid analysis shall accompany all biosolids that are land applied.

Notification, Reporting and Recordkeeping:

The Annual Biosolid Report is due February 19. of each year for the previous years land applied biosolid. Part of this report is the submittal of the daily site logs, which have the date, time, and quantity gal-lb. N/acre land applied for each tank-batch land applied. Site log shall have a scaled map showing the location that coincides with load recorded on the daily site log.

Annual Report shall have a signed copy of the certification statements for pathogen reduction, vector attraction reduction and biosolid has been land applied at approved agronomic loading. Person signing statements should be the operator of record at the treatment plant. The operator shall shown how the volatile solids reduction was achieved i.e., time and temperature, the Van Kleek equation filled out with digester records (MCRT), bench scale test, sour test or any other EPA approved alternative method appropriated for biosolid generated at your facility. Certification of pathogen reduction is required and is satisfied by submittal of microbial test results in the Annual Biosolid Report or PSRP equivalent. AU the previous year's biosolid sampling and analysis that is required by the permit shall be included in you're Annual Biosolid Report (in an appendix).

Biosolid Analysis: Annually, Heard Farms generates approximately 140 dry tons of biosolids. These solids contain about 2370 pound (lb.) total nitrogen (N) of which about 1662 pounds is in an available form of nitrogen (N03-N02, and NH3). Other nutrients include 4243 lb., phosphorus (P), 889-lb. potassium (K), and has a pH of approximately 7. The Fecal Coliform org/ 100 mg shall be less than 2,000,000 MPN to be a Class B biosolids (pathogen reduction requirement).

From the Heard Farm's 2001 biosolids analysis (Attachment 2) the following is a representative sampling of the biosolid metal concentration. Heard Evaluation Report December 12,2011 File Number 109363 Page 29

Metal Pound #/yr. #/acre-yr. site life

Arsenic (As) 31b. 0.06 lb. 610 yr. Cadmium (Cd) 1.51b. 0.03 lb. 1159 yr. Chromium(Cr) 5.0 lb. 0.09 lb. 29733 yr. Copper (Cu) 262 lb. 4.9 lb. 273 yr. Lead (PB) 141b. 0.3 lb. 890 yr. Mercury (Hg) 0.6 lb. 0.01 lb. 1516 yr. Molybdenum (Mo) 31b. 0.06 lb. 268 yr. Nickel (Ni) 81b. 0.151b. 2498 yr. Selenium (Se) 31b. 0.06 lb. 1487 yr. Zinc (Zn) 750 lb. 14. lb. 178 yr.

From the agronomic analysis the Heard Farms needs approximately 23 acres to land apply on to handle their annual biosolid production. The site life base on land application on 50 acres (Wells site #1 ~20 acres and site #2 ~30-acres) would be limited to 178 years based Zinc metal loading.

Transportation and Land Application: Biosolids are off loaded into a Heard Farm treatment plant's headworks. The septage loading area is impounded in case of accidental spillage of septage during the truck off-loading process. This area has a drain that ties back into the headworks of the plant. During the summer months (June 1 through October 31) biosolids are land applied on Department authorized sites (Well property ~50 acres total). The biosolid land application sites are capable of assimilating 6,000-lb. total nitrogen production. Heard Farm's facility has generated approximately 500,000 gallons of liquid biosolid in the last four- (4) years of operation. The biosolid is approximately 6.4% solids (93.6 % water); this is equivalent to 226,880 total pounds solid, or 2370 lb. total nitrogen. All biosolid are to be land applied at the approved agronomic cited in the site authorization letter, (Typical nitrogen loading for pasture in Douglas County is 100 lb. total N per acre -yr.).

In event biosolids are spilled between the treatment facility and the land application site, Heard Farm's shall contain the spill, lime, absorb (via sand) and remove spilled biosolids with a pumper truck, front end loader or shoves and dispose of the spillage at a Department authorized application or disposal site.

All spills into waters of the state or 42 gallons or more on the ground surface shall be reported to immediately to Oregon Emergency Response System (OERs) at 1-800-452-0311. All spills shall be report to the regional biosolids coordinator at (541) 440-3338.

ATTACHMENT #6 Wastewater System Classification Worksheet for Operator Certification Heard Farms Inc.,

General Requirements (OAR 340-049-0015) - Each owner of a regulated wastewater system must have its system supervised by one or more operators who hold a valid certificate for the type of system, wastewater treatment or collection, and at a grade equal to or greater than the wastewater system classification as defined in OAR-340-049-0020 and 0025. DEQ will advise system owners of the classification of their systems as a permit action. As the classification establishes the operator certificate type and grade required for compliance, It needs to be set prior to "start-up" of a new or upgraded and/or expanded facility.

Wastewater treatment system classifications will be derived from the total points assigned based on criteria shown in OAR 340-049-0025 (see Classification Worksheet). Collection system classifications are based on design population or population equivalent to be served by a wastewater treatment system (see Worksheet),

Upon written notice to the wastewater system owner, DEQ may classify a wastewater treatment system higher than the classification based on accumulated points if the complexity of a treatment system is not reflected in the criteria(see Worksheet examples). If deemed appropriate, DEQ may classify a wastewater collection system higher than the classification based on population when a Class I by population will have significant pumping of sewage including STEP or other pumping that may warrant a Class II designation. In either case, designation must be consistent with the intent of the classification system (see OAR 340-049-0020(4) & (5)).

Classification of Wastewater Systems (OAR 340-049-0020) All wastewater systems regulated under OAR 340-049 will be classified by DEQ as wastewater treatment systems and/or wastewater collection systems, as appropriate, in accordance with the following classification system:

Wastewater Treatment Systems Wastewater Collection Systems Class I - 30 total points or less Class I -1,500 or less design population Class II - 31-55 total points Class II -1,501 to 15,000 design population Class III - 56-75 total points Class III -15,001 to 50,000 design population Class IV - 76 or more points Class IV - 50,001 or more design population

Definitions used in these regulations unless otherwise required by context (see OAR 340-049-0010): "Average Dry Weather Flow" (ADWF) means the design average dry weather flow capacity of the wastewater treatment system in gallons per day or Million Gallons per Day (MGD), as approved by the Department. "Industrial Waste" means liquid wastes from an industrial or commercial process discharged Into a wastewater system for conveyance and treatment. "NPDES Permit" means a waste discharge permit issued in accordance with requirements and procedures of the National Pollutant Discharge Elimination System authorized by Section 402 of the Federal Clean Water Act and OAR 340, Division 45. "Population" means the design population of the wastewater system represented as the number of people or the population equivalent the system is designed to serve. Equivalent population ordinarily is determined based on 70 gallons per person per day average dry weather flow (ADWF) or 0.17 lbs. BOD5 per person per day, whichever is greater.

"Wastewater" or "sewage" means the water-carried human or animal waste from residences, buildings, industrial establishments or other places, together with such groundwater infiltration and surface water as may be present. The admixture of domestic and industrial waste or other by-products, such as sludge, is also considered wastewater or sewage. "Wastewater Treatment System" or "Sewage Treatment System" means any structure, equipment or process for treating and disposing of, or recycling or reusing wastewater and sludge (Including industrial waste) that is discharged to the wastewater system. "Wastewater Collection System" or "Sewage Collection System" means the trunks, arterials, pumps, pump/lift stations, piping and other appurtenances necessary to collect and carry away wastewater or other liquid waste treatable in a community or private wastewater treatment facility. "Wastewater System" means "Sewage Treatment Works" defined in ORS 448.405 as any structure, equipment or process required to collect, carry away and treat domestic waste and dispose of sewage as defined in ORS 454.010. Typically, components of a wastewater system include a wastewater collection system and a wastewater treatment system. Heard Evaluation Report December 12, 2011 File Number 109363 Page 35

Attachment 7 Volatile Solids Reduction

Calculation of the % volatile solids reduction is to be based on comparison of a representative grab sample of total and volatile solids entering each digester (a weighted blend of the primary and secondary clarifier solids) and a representative composite sample of the solids existing each digester withdrawal line. Composite samples of the influent shall consist of at least four samples; each collected at approximately even intervals over an eight (8) hour period.

In the past we've used the Van Kleeck equation for digesters. The assumption that there is no grit accumulation in the digester. This volatile solids equation assumes the fixedsolid s input equals the fixedsolid s output. The Van Kleeck equation is appropriate if the digester decatante is low in total solids. The Van Kleeck equation can be used to calculate the volatile solids reduction for a digester that decants provided VSb equal VSd.

FVSR: Fractional Volatile Solids Reduction

FVSR-1-VSb *(l-VSf)/VSf(l-VSb)

VSf Feed Sludge Fractional Volatile Solid, (kg/kg) VSb Digested Sludge (digester bottom) Fractional Volatile Solids, (kg/kg) VSd Decantate Fractional Volatile Solids For this equation to be valid VSb must equal VSd.

For digesters with decant withdrawal (decant high in solids) and no grit accumulation, where the volatile and fixed concentrations are known for all streams as well as the volumetric flow rates for the decant and digester sludge then the Approximate Mass Balance equation should be used.

FVSR: Fractional Volatile Solids Reduction

FVSR = Fyb - Byb - Dyd / Fyb

Fyb (F) Feed Sludge Volumetric Flow Rate (m3/d) (yb) Feed Sludge Volatile Solids Concentration (kg/ m3)

Byb (B) Digester Sludge (bottom) Volumetric Flow Rate (m3/d) (Bb) Digester Sludge (bottom) Volatile Solids Concentration (kg/ m3)

Dyd (D) Decantate Volumetric Flow Rate (m3/d) (yd) Decantate Volumetric Solids Concentration (kg/ m3) Because the Aerobic digester is cleaned every year the assumption is there is no grit accumulation in the digestive process.

Assumptions: Fixed Solids and Volatile Flows Streams.
