Based on this review, I have the following comments. From the submitted information, the effluent that will be discharged into the existing soil absorption system will be treated to a higher level than is currently being done by the existing wastewater disposal system. In fact, it appears that you are resolving several existing problems regarding vertical separation distances between the groundwater and the lowest part of the seepage pit. With the general improvement being made in regards to separation distances and with a higher treated wastewater being discharged, your waiver requests are justifiable. Therefore, in accordance with the provisions of 18 AAC 80.030 Drinking Water Regulations, the following waivers are granted: 1. From Class A Public Water System Source Well To Biocycle Treatment Unit from 200 feet to 135 feet - To closest point of existing soil absorption system from 200 feet to 122 feet 2. From the lowest part of existing soil absorption system and the highest groundwater elevation from four feet to two feet These waivers will remain valid, as long as the following requirements are addressed. 1. Verification that all soil absorption systems not being used to accept Robert A. Shafer, P.E. 2 wastewater from the Biocycle Treatment System decommissioned will need to be submitted to this office. August 19, 1994 were properly Copies of all analytical results from the required monitoring program on the effluent from the Biocycle system will need to be provided to this office. One sample of the inffleunt will need to be taken during the 12 month testing period and analyzed for the same parameters as the effluent. This waiver does not imply the granting of any additional authorizations, nor obligate any state, federal, or local regulatory body to grant required authorizations.

The quality of effluent from the Biocycle Waste Water Treatment System exceeds that of the effluent from a septic tank. Information on the design capacity, ventilation and location requirements is given in Sections 3.2, 4.6 and 2.4 of this Certificate. The Bipcycle Waste Water Treatment System can be 'used in domestic situations Where septic tank systems are not acceptable, where sites do not comply with the recommendations of S.R.6. 1991 Septic Tank Systems Recommendations for Domestic Effluent Treatment and Disposal from a Single Dwelling House and/or where septic tank systems have been known to fail. 12 2.1 DESCRIPTION This Certificate relates to the Biocycle Waste Water Treatment System, comprising a four stage process, contained in a 2.28 m outer diameter outer tank and a 0.95 m diameter inner tank, each subdivided into two sections giving four chambers. (See Fig. 1). The waste water flows by gravity through each chamber in succession. The function of each stage is described below. 1) Reception and primary treatment (Chamber A) Settlement of solids resulting in about 20-30% BOD~ load reduction occurs in Chamber A. Inorganic materials such as grit and sand will also be removed by settlement. Floatable substances · such as fat and grease may be retained and any floatables that arise in the clarification stage (see 2.1 (3)) will be returned to this chamber. Substantial reduction in the volume of settled sludge occurs by anaerobic digestion and this is assisted by adding some of the activated sludge from the next (aeration) stage of the treatment process. It is normal for a thick crust or scum to form on the surface of the chamber. 2) Aeration (Chamber B) The discharge from Chamber A flows by gravity to Chamber B where the organic content is almost totally degraded by a culture of bacteria referred to as activated sludge. Oxygen, to support the degradation processes, is introduced by a small air pump and the bacteria are supported on a purpose designed submerged plastic medium. 3) Clarification (Chamber C) The discharge from the aeration stage drains to the clarification stage (Chamber C), where separation · by settlement of the biological solids, generated in 'the previous stage, occurs. The settled solids are mainly returned to the primary treatment stage (Chamber A). 4) Pump (Chamber D) The clarified waste water drains to the sump and from there it is pumped to the disposal location. Disinfection of clarified waste water is available as an option. 5) Safety Alarms Within the Biocycle Waste Water Treatment System three alarms are installed as warning devices. An Part D - Materials and Workmanship Biocycle waste water treatment tanks are made of acceptable materials as indicated in Part 4 of this Certificate. alarm plate (audio/visual), is supplied to be installed within the house. The alarm plate is similar to an ordinary light switch with two coloured lights. A switch provides for the alarm to sound and to be switched to the "mute" position when heard. The alarm panel is incorporated into an E.L.C.B. unit which is designed as an extra safeguard in the event of an electrical fault. The two lights indicate (i) The high WATER level alarm - designed to sound if the water level in the irrigation/disinfectant chamber reaches a certain level. This indicates that the submersible pump is malfunctioning. (ii) The AIR pressure alarm - designed to sound if the blower ceases to operate, or if the diaphragm ruptures. (iii) The POWER supply alarm will activate in the event of a power failure to the system. The house holder is required to contact the company when this occurs and Biocycle Limited is obliged to respond within 48 hours. 2.2 MANUFACTURE The outer tank, tank riser section and lid are designed and constructed from steel fibre reinforced concrete in accordance with the requirements of AS 1546 - 1990 'Australian Standard for Small Septic Tanks; The inner tank and manhole cover are designed and constructed from glass reinforced polyester in accordance with BS 4994:1987 Specification for design and construction of vessels and tanks in reinforced plastics. Each system design is assembled and fitted at the manufacturer's works with the air diffuser system, pump, plastic support media, system internals and pipework. Treated waste water disposal (irrigation) pipework and electrical connections are completed on-site. 2.3 DELIVERY, STORAGE AND MARKING The tanks are completed ready for delivery at the manufacturer's works. Off-loading must be carefully supervised using chains, steel cables or lifting bars rated in excess of five tonnes and should conform with the requirements of the Safety in Industry Act 1980. The manufacturer's instructions must be followed to avoid damage to the tanks during off-loading and placing in the excavation. A crane or other suitable lifting equipment must be employed. The tanks are supplied with full installation instructions and are labelled on the outside to indicate the lAB identification Mark incorporating the number of this Certificate. 2.4 INSTALLATION PROCEDURE 2.4.1 General The Biocycle Waste Water Treatment System must be installed in accordance with-~he manufacturers instructions. The excavation must be of sufficient depth and width to allow for safe and easy emplacement of the tank. Generally a hole of 3 m x 3 m is satisfactory and the depth will be largely determined by the invert level of the drain from the premises to be served by the Biocycle Waste Water Treatment System. The bottom of the excavation should be dry and level, with no sharp rocks or large stones protruding. In the case of soft or unstable soils it may be necessary to put in Place a levelled layer of compacted hardcore (about'200 mm) or a concrete pad (about 150 mm thick). Care must be taken to ensure that the tank is truly vertical when it is lowered on to the bottom of the excavation. If it is not, it must be raised and the bottom of the excavation relevelled until it is absolutely level. The tank' inlet port must be in line with the drain from the premises being served. The excavation should be backfilled to the inlet invert level with materials such as sand or gravel. Materials from the excavation may be used provided rocks and large stones are excluded. Builders rubble should not be used. The backfill should be carefully consolidated around the tank. At all stages of installation, care should be taken to avoid accidental entry of foreign matter, (clay, stones, rubble, scrap), into the tank interior. Except when work is taking place in the interior, the cover should be kept in place at all times. The lifting holes must be sealed with the plugs provided and the surfaces sealed with epoxy resin. 2.4.2 Location The Biocycle Waste Water Treatment System tank should not be located closer than 1.5 times the depth to the bottom of the tank or 3 m (whichever is greater) to any building, road or wall so as to avoid damage to foundations during excavation for the tank. It should be located so that there is access for maintenance and for desludging by vacuum tanker. The tank should not be located in any area where vehicles could traverse or damage it. 2.4.3 Treated Waste Water Disposal Treated waste water may be disposed of by any of the following means (See Fig. 1): a) Surface Irrigation -- disposal assisted by evaporation and vegetation. or b) Subsurface Irrigation -- disposal assisted by evapotranspiration and vegetation, (direct root feeder system, or subsurface disposal field). or c) Discharge to surface water in a ditch or drain. A licence to discharge to waters will be required from the local authority to comply with the Water Pollution Acts (1977-i990), if this option is selected. The extent of the disposal or irrigation area will be determined by the population served and the soil percolation value at the site in accordance with the guidelines given in Table 1. For each site a test shall be carried out in accordance with the Biocycle Irrigation Test Procedure in order to confirm the suitability of the irrigation system. Table I: General Guidance for the Sizing of Irrigation Area (nC). Percolation Value (seconds/mm) Population 30-90 120-180 21 0-270 4 50 70 110 6 60 90 130 8 70 110 150 These guidelines apply to both surface and sub-surface irrigation systems. For sites where the measured percolation value is less than 30 (sec/mm) or greater than 270 (sec/mm) Biocycle Limited should be consulted regarding the design of the irrigation system. Different configurations of irrigation areas (circular, square etc.) are acceptable. This also applies to sites Where split irrigation areas are needed t° obtain the recommended total area. No point of the irrigation area should be closer that 5 m to any habitable building, 1 m to boundary walls or fences and 3 m from any water course. The separation distance from wells should be not less than 20 m except in the case of very sandy soils or gravels, where a minimum distance of 40 m should be maintained. The irrigation area should be down gradient of any nearby well. Where it is not possible to locate the irrigation area down gradient of any well including those on neighbouring properties, a separation distance of at least 100 m, depending on percolation conditions, must be maintained. At least 1 m of overburden should be present between the highest level of the water table and the invert level of the irrigation system. A raised bank of topsoil may be required to accommodate this. 2.5 COMMISSIONING Commissioning will be carried out by Biocycle service technicians after installation is complete and all services are connected.

A single system may therefore be used to treat the waste water from two or three households, provided the total population served does not exceed 8 persons. It is suitable for installation at sites where a septic tank and percolation system does not afford an environmentally safe and acceptable means of disposing of domestic waste water. Such sites include those where the water table is high and where soil types do not afford good percolation. Where the disinfection option is employed it may be used .at sites where bacteriological contamination of ground water must also be avoided. To ensure optimum efficiency the drainage of the premises served must be checked to ensure that storm water from roofs and paved surfaces does not discharge to the system. The system is designed and installed generally in accordance with BS 6297:1983 Code of practice for design and installation of small sewage treatment works and cesspools. Due to the high quality effluent treatment achieved (see Table 2 of this Certificate) the Biocycle Waste Water Treatment System can be installed close to habitable buildings, as indicated in Section 2.4.2. and Section 2.4.3 subject to any special requirements of the particular site. The system intentionally does not have an overflow disposal outlet. There is a minimum spare volumetric capacity of 2600 litres so that in the event of a pump malfunction it will continue to accept up to two to three days discharge from the premises. The monitoring system (see 3.2.5) will have alerted the owner to the malfunction and this will normally be corrected before overflow occurs. Where surface irrigation is employed the system is designed so that any overflow will be automatically disinfected, thus minimising the risk of any health hazard. 3.2 DESIGN BASIS Population served: 8 persons Hydraulic.load: · ' 180 litres/person/day Hydr~ul!c'load maximum: .. 250 litres/hour Organic loads: 0.05 kg BODs/person/day prin lamber: ': ~"':' -- chamber: · :--'~ .... m~nimum: 3.2.1 PUMPS' (a) IrrigationPumps 2100 litres ~2100 litres 500 litres 500 iitres 2600 litres Irrigation pumps are of standard submersible type and are selected to suit site conditions within the range - 130 Litres/minute/Sm head to 130 Litres/minute/8m head.

Design surface: 15 m2 per person Installed surface area: 120 m~ 3.2.3 DISINFECTION Disinfection of waste water is available as an option· A solid formulation, 70% active, of calcium hypochlorite [Ca(OCI)2] tablets is used. They are retained in a controlled release chamber so that under and over dosing does not occur. Replenishment is normally required twice per year and will be carried out by Biocycle Limited as part of the mandatory inspection and maintenance contract for each installation. 3.2.4 WASTE WATER QUALITY Table 2: Treated waste water characteristics*: pH 6.5 - 7.5 Biochemical Oxygen Demand < 20 mg/I Suspended Solids < 30 mg/I Ammonia < 10 mg/I N Nitrate 5 - 10 mg/I N Total phosphorus < 5 mg/I P E. coil (disinfection option). < 30 MPN per 100 mi *The concentrations of ammonia and nitrate depend on the length of time the system has been in use. The pH, BOD, suspended solids and phosphorus concentrations would normally be attained within a few weeks of commissioning. Each Biocycle Waste Water Treatment System is supplied with a monitoring system to alert the owner to malfunctions. The tank is fitted with a liquid level detector which will warn of a pump malfunction. A pressure detector will warn of an air blower malfunction. In addition a power supply alarm will activate in the event of a power failure to the Biocycle unit. These detectors are connected to a fault indicator 4.1 ENVIRONMENTAL AssESsMENT~ ' :: The treated waste water from a number of working installations hasbeen ,.comPrehensivelY monitored for 2 years. The test resUlts show that valueS stated for.the parameters listed in Table 2are consistently achieVable over a range =of oPerating C0~ditions. : ~ 4.2 STRENGTH The design and testing of the plant has been assessed as satisfactory. The tanks have adequate re.~istance to handling stresses and the loads applied by ground pressure and internal liquid loads. The cover is designed for occasional pedestrian traffic. It must not be subject to traffic from vehicles or livestock. 4.3 WATER PENETRATION The plant and tank with its pipe connections when correctly installed will not allow seepage either into or from the surrounding soil. 4.4 DURABILITY The System (excepting pumps) when installed, used and maintained in accordance with the requirements of this Certificate will have a life in excess of 30 years. 4.5 CLEANING AND MAINTENANCE All Biocycle units require twice yearly maintenance. The Certificate holder operates a maintenance system to clean the tank components, check system operation and replenish disinfectant tablets where appropriate. As part of routine maintenance the owner wilt be notified of any desludging requirements which should be carried out in accordance with manufacturers instructions. The frequency of desludging will vary and, on average, desludging will be required once every 2 to 4 years. All maintenance inspections are recorded and notified to the Local Authority by Biocycle Limited. 4.6 SAFETY 4.6.1 Safety of Personnel The Biocycle Plant is installed below ground level and all covers are securely fixed to prevent unauthorised access. Ventilation is provided through the soil pipe and, where necessary, via the manhole cover.

BIOCYCLE WASTEWATER TREATMENT PLANTS A SUITABLE ALTERNATIVE Paper Presented to the Australian Institute of Health SUrveyors (South Australian Division) Mount Gambier South Australia - 26th November 1987 by Ian Walte: Managing Director BIOCYCLE Pry Ltd. Amended 12th May, 1989. THE BIOCYCLE AEROBIC WASTEWATER TREATMENT SYSTEMS: INTRODUCTION The effective collection, treatment and disposal of human waste and wastewater has been a puzzle and a challenge to humans since time began. It is not intended to give a potted ],[story of how we have arrived at the stage we are today, but suffice to say that collection and treatment systems have developed since last century to cope with the increasing demands for good public sanitation practices. Authorities, both state and local, have established reticulation systems for collection, and have developed treatment facilities to cope with quantities of wastes generated from communities, both large and small. What will be discussed in this paper is the function and operation of the BIOCYCLE system which provides a higher level of treatment than previously obtained, and which allows the recycling of the wastewater effluent. The benefits of the Aerobic Wastewater Treatment System will become obvious. The recycling of treated effluent is now a major topic in itself, and others will advance this cause in the passage of time through awareness campaigns and government encouragement. A BIOCYCLE aerobic treatment unit is a packaged wastewater treatment plant for domestic application when mainline sewage is not available, or where the soll types or terrain do not'suit conventional site disposal systems, but particularly when environmental damage wishes to be avoided. It provides an excellent and viable alternative for those areas which are intended to be provided with a reticulated sewage scheme in years to come. The treated effluent from a BIOCYCLE aerobic treatment plant is ideal for garden or landscape irrigation. In certain cold climates when dispersed via sub-soll drainage, it has a distinct advantage over traditional on-site disposal systems because of its sludge-free condition. -2- HOW IT WORKS Biological sewage treatment plants for fairly small and sometimes quite large establishments have been available for many years. Such systems are generally based on the activated sludge principle, followed by clarification by means of settling; and tertiary treatment by means of chlorination or pondlng. The BIOCYCLE aerobic treatment plants, used for single dwellings and small commercial concerns are somewhat different from the conventional package treatment plant. THE SYSTEM AND ITS FUNCTIONS The BIOCYCLE system is divided into four principal chambers. RECEIVING CHAMBER (anaerobic/septic) AERATION CHAMBER CLARIFICATION CHAMBER 4. IRRIGATION (pump) CHAMBER CHLORINATION takes plaace between chambers 3 and 4. THE RECEIVING CHAMBER All wastes are received into this first chamber. Anaerobic digestion of solids occur as a primary treatment achieving a reduction in the B.O.D.5 level (organic loading) of up to 40%, This chamber also provides other valuable service to the Biocycle system in that it acts as a receiving chamber for not only organic waste but also inorganic matter, sludge and skimmed material (sent back from the Clarification chamber) and cellulous materials that require longer retention for breakdown. The introduction of Aerated/Activated sludge from the Clarification chamber excites and further assists the digestion of solids. sludge, (the ultimate by-product of waste), is accumulated in this chamber and when desludglng is required, (estimated at 9 years in the average household), then only this chamber requires pumping out. AERATION CHAMBER Whilst the Receiving Chamber digests a percentage of the organic loading, the Aeration Chamber is capable of achieving the required treatment standard without the assistance of the first chamber. ~. -3- The displaced, and partially treated waste flows from the receiving chamber to this chamber and air is supplied by means of a Blower (compressor) and distributed via diffusers. The amount of air regulred is dependent upon a calculation based on the anticipated organic loading (B.O.D.5) and the transfer of oxygen into the water, (increasing the dissolved oxygen level). The blower used in the BIOCYCLE system for the individual household is specified to treat a loading of 2 800 litres per day with a B.O.D.5 influent loading of 250m9. per litre. The Aeration chamber contains a submerged media upon which grow both aerobic and anaerobic bacteria. The media is located where beneficial bacteria thrive. A zoogleal film of bacterial and algal matrix develops on this media thus providing biological treatment. The type of media used in the BIOCYCLE system has a discreet flow pattern with a big surface area to volume ratio and self cleansing action. The Aeration Chamber in the BIOCYCLE system is however different in theory from an ordinary suspended growth system. Both sub-surface anaerobic and surface aerobic micro-organisms grow on the submerged .media. However the anaerobic bacterial action results in a continuous reduction of the media growth and therefore a reduction in biological sludge accumulation. Nevertheless, as the thickness of the materlal grows, some separation caused by the high liquid movement, will occur. This separation will ultimately result in excess sludge in the aeration compartments which will ultimately flow to the next chamber, (Clarification Chamber), for pick up and return to the Receiving Chamber. An amount of activated sludge in the Aeration Chamber plays an important role, allowing additional micro-organisms to grow on the sludge particles further assisting digestion. In the BIOCYCLE system the capacity of this chamber allows for a 24 hour detention time of the influent load, (16 hours, generally being regarded as sufficient: in some commercial applications, a greater detention period may be necessary). CLARIFICATION CHAMBER After aeration, the effluent flows into this chamber and is allowed to settle down under quiescent conditions. Sludge/undigested material settles to the bottom where it is picked up and returned to the Receiving Chamber. Floating matter is also collected and returned to the Receiving Chamber. -4- The method adopted in the return of settled or floating matter is via a venturi pump, (run off the air supply to the Aeration Chamber) and is capable of automatic and continuous operation. The benefit of a continuous sludge/skimmer return to the Receiving chamber provides a continuous supply of "food" to the plant and thus ensures a "healthy" system during periods of zero flow or extended vacancy of a residence. From the clarification chamber the effluent is drawn-off at below the surface level and flows to the pump chamber. CHLORINATION During thls flow the effluent comes into contact with calcium hypochlorite tablets (guaranteed 70% active). Within the BIOCYCLE Chlorinator a weir has been set and calibrated to suit above normal water usage, and is designed for a flow rate generated by a household of up to 10 persons, and to provide sufficient Chlorine stocks under maximum usage with in-built safety factors to cover all forseeable circumstances between the quarterly maintenance calls with a 100% safety margin. IRRIGATION (pump) CHAMBER After disinfection, the aerated, settled and chlorinated water is retained in this chamber to ensure a minimum 20 to .30 minutes contact time then pumped via an irrigation system to wherever it is required in the garden landscape area of the property. FINAL EFFLUENT QUALITY A properly maintained plant produces treated waste water of very high quality Both B.O.D.5 and suspended solids ($.$. OR N.F.S.), are required by all Government departments in Australia to be not greater than 20/30 mg /litre . In relation to Faecal Coliforms the following standards: Not more than 30 Faecal Coliform Organisms per 100 mi. FREE CHLORINE - Not less than 0.5 mg. per lltre (0.5 ppm). All tests on the BIOCYCLE unit thus far have never recorded any presence of faecal coliform organisms. -5- IN PERIODS OF VACANCY: A user of a BIOCYCLE system is advised to contact the company if they expect periods of vacancy greater than three (3) months. INSTALLATION OF A BIOCYCLE SYSTEM. The same installation procedures should be followed as if installing the traditional septic tank. APPROVALS: In Australia, and in both the cases of a new installation into a new.home or in an existing dwelling, it is required to make application to the local Council for the approval of the installation of a BIOCYCLE Aerobic Treatment System. BIOCYCLE IRRIGATION SPECIFICATIONS The BIOCYCLE systems irrigation water is discharged via a 25mm polythene pipe through a series of 25 to 30 micro,et sprayheads. These sprays are placed at intervals in the required positions on the pipe from the tank. Although the submersible pump in the irrigation chamber is capable of a discharge'rate of 0.13 cubic metres per minute, the type of sprayheads and friction loss brought about by the filter and irrigation line reduces the discharge rate to .75 lttres per minute when 25 sprayheads are used, therefore evacuating 200 litres in approximately 10 minutes. In certain situations additional sprayheads may be required further reducing the flow rate. The minimum area required for irrigation varies depending on site conditions, however an area bf about 100 square metres is the generally accepted average. This may be in any configuration and with some innovative planning can provide for a fully integrated irrigation system and provide genuine landscaping benefits. After irrigation, nutrient removal is achieved. Irrigation of recreational areas and growing vegetables or fruit must be avoided. Discharge or run-off into stormwater easements or other drainage channels is not recommended. All effluents must be disposed of within the boundaries of the property. In the case of "split" irrigation areas, BIOCYCLE will instal valves necessary to allow the alternate use. The system is designed to ensure that at least one irrigation area is available for use at all times. The Irrigation area should ideally have a vegetative cover and the System is designed to be operative with an evaporation rate of about 6mm per day. If the irrigation area consists of shrubs and natives with a plant cover of say 40% we would es.timate.a transpiration rate of about 30% of deposited water. COMMISSIONING: It should be remembered that it might be necessary to instal the BIOCYCLE System prior to building commencement, particularly when the property, when built, may preclude physical access to the preferred location on your site or if it is required for the system to be used during building operations, however some time will probably elapse between installation and commissioning of the system. The normal BIOCYCLE installation leaves the' System ready for automatic commissioning. As the BIOCYCLE is a completely natural biological process, time must be given for the bacteria cultures to form. It will generally take up to about four weeks for this to occur. Whilst this settling period takes place slight odours may come from within the system. To assist with a more rapid settling in period it is recommended that a cup full of ordinary garden llme is deposited in the Primary chamber daily for the first week of operation. This assists the breakdown of solids and usually halves the settling-in period, or alternatively, a bucket full of waste from an operating septic system will achieve the desired effect. There are also several proprietary lines of "enzyme accelerators" that can be used. IN-BUILT SAFETY FACTORS AND ALARMS Within the Biocycle System two alarms are installed as warning devices. An Alarm Plate (audio/visual) is supplied to be installed within the house, (the kitchen being the most preferred room). The alarm plate is similar to an ordinary light switch with two coloured lights. A switch provides for the alarm to sound and to be switched to the "mute" position when heard. The two lights indicate if: 1. The high WATER level alarm - designed to sound if the water level in the Irrigation/Disinfectant Chamber reaches a certain level. This indicates that the submersible pump is malfunctioning. 2. The AIR pressure alarm - designed to sound if the diaphragm blower ceases to operate. --.7-- The householder is required to contac% the company when this occurs and BIOCYCLE PTY. LIMITED is obligated to respond within 24 hours. Further, the domestic BIOCYCLE design provides for an air space that is capable of accepting not less than an additional I 200 litres, should the irrigation pump fail. This gives at least 2 days capacity, in the average household safety span, prior to the system overflowing. However, even if the system overflows there are sufficient chlorine stocks within the system that dissolve as the liquld level rises, to render the overflow relatively harmless. MAINTENANCE OF AEROBIC TREATMENT PLANTS All BIOCYCLE units require quarterly maintenance. In the flrzt year after commissioning, the labour is included in the sale price of the system and the only charge ks for chlorine tablet replenishment. In the second and ensuing years, the current cost of this is $175.00, but includes all chlorine tablet replenishment. NOTE: In Australia there are no requlrements for maintenance or testing of the traditional septic, and consequently, there is no knowledge after installation as to whether the septic is working efficiently or whether it has completely failed. ACCEPTANCE OF THE BIOCYCLE SYSTEM BIOCYCLE PTY. LIMITED. first gained approval to commence manufacture of their systems in New South Wales in November 1985. Since then, blanket approvals have been gained in South Australia/Northern Territory and Queensland. Blanket approval is pending in Western Australia. Preliminary approval has been gained in New Zealand with the first two systems having now been installed in that country and the first of five contracted systems have been installed in New Guinea. Negotiations are being concluded on technology transfer agreements in Bahrain, Saudl Arabia, Italy, Israel, the U.S.A. and Ireland. There are now approaching 1000 domestic BIOCYCLE systems in operation in Australia and about 100 larger commercial (BIOCYCLE Jumbo) units in operation. The acceptance by the general public, and local and state authorities is mushrooming, particularly in New South Wales, and Queensland. -8- Many Local Government Areas now "exclusively" specify the BIOCYLE system or similar in preference to the out-moded septic tank. CONCLUSION The BIOCYCLE systems achieve the primary objective of high quality effluent that can be recycled for irrigation purposes. The BIOCYCLE system overcomes the significant community stress caused by failed on-site disposal, illegal.discharge and subsequent pollution of the local environment. The BIOCYCLE system may relieve the community cost where a reticulated mains sewer scheme is not economically viable. Finally, the BIOCYCLE system is an acceptable alternative. IAN G. WAITE, MANAGING DIRECTOR, BIOCYCLE PTY. LIMITED, " ~ BIOCYCLE TEST RESULTS TESTING OF THE BIOCYCLE UNIT BY THE NSW DEPARTMENT OF HEALTH WAS CONDUCTED BY STAFF FROM THE NORTHERN METROPOLITAN REGIONAL OFFICE OF THAT DEPARTMENT. SAMPLES FOR B.O.D. 5 AND SUSPENDED SOLIDS WERE TAKEN BY THOSE OFFICERS TO AUSTRALIAN ANALYTICAL LABORATORIES (a National Approved Testing Authority {NATA}). FAECAL COLIFORM SAMPLES WERE TESTED AT THEIR OWN LABORATORIES. THE TEST SITE HAD TO BE APPROVED BY THE DEPARTMENT AND THE SYSTEM WAS PLACED UNDER LOCK AND KEY DURING THE TEST PERIOD WITH A DEPARTMENTAL OFFICER IN CHARGE HAVING THE ONLY KEY FOR ACCESS. IN SOUTH AUSTRALIA, THE SOUTH AUSTRALIAN HEALTH COMMISSION WERE SATIS~FED WITH THE TESTING CRITERIA OF THE NSW DEPARTMENT OF HEALTH AND ACCEPTED THEIR TEST RESULTS. HOWEVER, AFTER INSTALLATION OF THE FIRST BIOCYCLE SYSTEM IN THAT STATE, OFFICERS OF THE S.A. GOVERNMENT MADE PERIODIC INSPECTIONS OF THE SYSTEM AND TOOK RANDOM SAMPLE TESTS, ALL OF WHICH FELL WITHIN THEIR GUIDLINES. NONE OF THEIR TEST RESULTS HAVE BEEN MADE AVAILABLE TO BIOCYCLE. IN THE NORTHERN TERRITORY, THEIR GOVERNMENT ACCEPTED THE SOUTH AUSTRALIAN RECOMMENDATION. IN NEW ZEALAND, THEY ACCEPTED THE NSW APPROVALS. IN QUEENSLAND, A DIFFERENT SYSTEM OF EVALUATION OF THE BIOCYCLE SYSTEM WAS REQUIRED AND THAT PROCEDURE AND RESULTS ARE LISTED HEREON. IN NEW GUINEA, THEY ACCEPTED THE SYSTEM ON THE MERITS OF THE AUSTRALIAN APPROVALS. NO FORMAL APPLICATION HAD TO BE MADE AND CONSEQUENTLY NO FORMAL ACCEPTANCE HAS BEEN RECEIVED. IN WESTERN AUSTRALIA, THE W.A. HEALTH DEPARTMENT HAS APPOINTED A SENIOR HEALTH SURVEYOR FROM KALUMUNDA SHIRE COUNCIL TO CONDUCT TESTING. THIS TESTING HAS INCLUDED RANDOM SAMPLING OF THE SYSTEM ON A WEEKLY BASIS FOR THE FIRST FOUR MONTHS, RANDOM FORTNIGHTLY TESTING ON A FORTNIGHTLY BASIS FOR THE NEXT TWO MONTHS, AND IS NOW CURRENTLY BEING TESTED ON A ONCE A MONTH RANDOM BASIS. IN W.A. IT HAS BEEN NECESSARY TO ALTER LEGISLATION TO ALLOW THE INTRODUCTION OF THE BIOCYCLE SYSTEM. WE HAVE BEEN VERBALLY ADVISED THAT THEIR HEALTH DEPARTMENT ARE SATISIFED WITH THE RESULTS OF THEIR TESTING BUT NONE OF THE RESULTS HAVE BEEN GIVEN TO US. AT THE TIME OF PREPARATION OF THIS REPORT WE UNDERSTAND THAT THE NECESSARY LEGISLATION HAS BEEN PUT BEFORE THEIR LOWER HOUSE AND WE ANTICIPATE FORMAL APPROVALS SHORTLY. IN TASMANIA, TESTING IS CURRENTLY BEING CONDUCTED BY THEIR HEALTH COMMISSION AND RESULTS HELD BY THEM. APPROVAL WAS OBTAINED FOR TASMANIA IN APRIL 1989.

S & S Engineering 17034 North Eagle River Loop, Suite 204 Eagle River, Alaska 99577 Subject: Lot 6, Borealis Alpha Subdivision, Waiver request, Anchorage, Alaska, ADEC Project Number 9521-W/W-229-054, Review Dear Mr. Shafer: I have reviewed your August 17, 1994 submittal, the information provided to this office on the Biocycle On-site Wastewater Treatment System, and the information in this office's files regarding the original waiver. Based on this review, I have the following comments. From the submitted information, the effluent that will be discharged into the existing soil absorption system will be treated to a higher level than is currently being done by the existing wastewater disposal system. In fact, it appears that you are resolving several existing problems regarding vertical separation distances between the groundwater and the lowest part of the seepage pit. With the general improvement being made in regards to separation distances and with a higher treated wastewater being discharged, your waiver requests are justifiable. Therefore, in accordance with the provisions of 18 AAC 80.030 Drinking Water Regulations, the following waivers are granted: 1. From Class A Public Water System Source Well To Biocycle Treatment Unit from 200 feet to 135 feet To closest point of existing soil absorption system from 200 feet to 122 feet 2. From the lowest part of existing soil absorption system and the highest groundwater elevation from four feet to two feet These waivers will remain valid, as long as the following requirements are addressed. 1.

The Department has reviewed the subject waiver request and hereby waives the horizontal separation distances between the well and the following sources of potential contaminations to: 122 feet for the existing crib, (1974) 122 feet for the existing leach line, 122 feet for the proposed leach line, 108 feet for the existing septic tank, (1980) (1989) (1974) The Department has granted these separation waivers, in part due to the understanding that a diversion valve will be installed and properly utilized within the wastewater system. This is to allow for half of the wastewater system to have adequate "resting time", to rejuvenate. Please be advised this is an important document and should remain with the deed of the house. These granted waivers are for a 4-Bedroom single family residence occupancy only. Sin erely, 'B~uce E.

Parks SRA Box 16?B X Anchorage, Ak 99507 Dear Mr. Parks: On November 29, 1980 we drilled'the testhole approximately 10 FL. From the end of the trench left open by spendlove the results are as follows: 0-3' S~IE, slight moisture (ML) 3-6' Silt, some gravel (GM) 6-9' Silt, one layer highly saturated (silt) (Mt) 9-12' Occasional gravel silt mix Mostly silt very plastic and~saturated.(ML) Bit wet on retrieval. After 2 minutes water was evident in the hole. The static level was approximately 9'. This depth matched the top of the water in the open trench. 1'he only assumption to be reached is that the water in the trench is groundwater and not water From the crib. IF I can be of any assistance, please let me know. Sincerely, Le-~o~. C.
