Dear Mr. Cowan: This letter is in reference to the materials received in this office July 11, 1997, addressing this office's review comments regarding a request for a waiver of the required vertical separation distance between the bottom of an on-site wastewater disposal system and the highest seasonal groundwater level. The Department has completed its review of the submitted materials which included a cover letter addressing the previous comments by this office (letter dated 3/14/97), additional water samples analysis from surrounding wells, topographic map, and effluent analysis from the installed BioCycle wastewater treatment system. Based upon this review and previously submitted information the Department has the following comments: Vertical Separation Waiver Request: After careful review of all submitted information pertaining to the requested waiver for a vertical separation distance of three (3) feet from the required four feet as specified under State Wastewater Disposal Regulations (18 AAC 72.025(D)) it appears that most of the previous comments of this office have been addressed. Therefore, in accordance with 18 AAC 72.025(D) conditional approval of the requested vertical separation distance of three feet from the bottom of a soil absorption system to the high seasonal groundwater level is granted subject to the following conditions: Ground water levels will need to be monitored annually at this site, either during the months of May or September when groundwater levels are likely to be at their highest level. If at anytime the groundwater level to the bottom of the system is less than three feet the soil absorption system will need to be raised. Mr. Robert Cowan 2 August 11, 1997 Annual monitoring results of the effluent produced from the BioCycle wastewater treatment plant will need to be submit[ed to ensure that it is operating properly. This approval does not imply the granting of additional authorizations nor does it obligate any other state, federal, or local regulatory body to grant required authorizations. Thank you for your cooperation with this Department, if there are any questions regarding the above, please do not hesitate to call.

S & S Engineering 17034 North Eagle River Loop, Suite 204 Eagle River, Alaska 99577 Subject: Lot 22, Block 2, Silver Crest Subdivision, Anchorage, Alaska, Waiver Request, AWPSA Project Number 9621~WV-127-044; Review Dear Mr. Cowan: This is in response to your submittal received in this office on July 8, 1996 requesting that the Department re-consider.your request regarding a letter of non-objection to the less than four foot separation distance between the lowest part of the soil absorption system and the seasonal high groundwater elevation. Both submittals note that a Bio-cycle unit was installed prior to the soil absorption system in question. I have reviewed the submitted information, this office's file on the above-referenced lot, and discussed this request with staff of the Municipality Of Anchorage, Department of Health and Human Services. There appears to be a discrepancy between the information that you provided to this office and what was requested in my June 4, 1996 letter. As an example, in my June 4, 1996 letter, I requested verification of the groundwater gradient, while in your submittal you discuss the static water levels of two wells without noting the possible groundwater flow direction or location of the wells in relationship to the soil absorption system in question. There is no endorsement from the Municipality of Anchorage for this waiver request. My review of nitrate data in the subdivision, there appears to be a trend towards elevated level of nitrates. After completing my second review of the submitted request, I must again deny your request for a vertical separation distance waivedletter of nonobjection for the existing three (3) feet between the lowest point of the soil absorption system and the highest ground water elevation is denied.

' H2 Septic tanks The Biocycle Waste Water Treatment System is a combined aerobic/anaerobic system and is suitable for application where mainline foul water drainage is not accessible. 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. 'fhe Bipcycle Waste Water 'Freatm~'~' System can be 'used in domesdc situations where s.. ,~c 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. B2 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 lhe 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- Materi¢~ and Workmanship Biocycle wast /ater 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.LC.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 lhe 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 supped 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 identification Mark incorporating the number of this Cedificate. 2.4 INS IALLA'IIL)hl PROCEDUltE 2.4.1 General '~he Biocycle Waste Water 'l,~atment 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 tim inved 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 botlom 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 lhe 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 7reared 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). c) Disc,,,.,rge 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 (1977-1990), 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 1: General Guidance for the Sizing of Irrigation Area (nC). Percolation Value (seconds/mm) Population 30--90 120--180 210-270 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 to 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. 3.1 GENERAL The Biocycle Waste Water Treatment System has been designed to treat domestic waste water arising from up to 8 persons. 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 wasle 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 lreatment works and cesspools. Due to the high quality effluent treatment achieved (see Table 2 of this Certificate) the Biocycle Waste Waler 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 lo three days discharge from the premises. Tile monitoring system (see 3.2.5) will have aleded 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 Hydraulic load maximum: 250 litres/hour Organic Ipads: 0.05 kg BQD¢/person/day Capacities: Reception and primary treatment: ~ 2100 Iitres Aeration chamber: .'. .:'. 2100 litres Clarification chamber: .. : .~ 500 litres Pump sump: · ' 500 litres Freeboard, minimum: 2600 litres 3,2.1 PUMPS' (a) Irrigation Pumps Irrigation pumps are of standard submersible type and are selected to suit site conditions within the range - 130 Litres/rninute/Sm head to 130 Litres/minute/8m head. Enclosures are to I P 6 8 in accordance with IEC 529-1989 'Degrees of.Protection. Provided by Enclosures'. All irrigation pumps use single,phase 220-240 volt 50 Hz motors with thermal overload protection. (b) Air Pump The air pump is designed for continuous service and provides long-term maintenance free operation. Enclosures are to I P 5 4 in accordance with lEO 529-1989 'Degrees o!

Design surface: 15 m* per person Installed sudace 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(OCl)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 wasle water characteristics*: pH Biochemical Oxygen Demand Suspended Solids Ammonia Nitrate Total phosphorus E. coli (disinfection option). 6.5 - 7.5 < 20 mg/I < 30 mg/I < 10 mg/I N 5 - 10 mg/I N < 5 mg/I P < 30 MPN per 100 mi 'The concentrations of ammonia and nitrate depend on the length of time the system has been in uso. The pH, BOD, suspended solids and phosphorus concentrations would normally be attained within a few weeks of commissioning. ~acb Biocycle Waste Water Treatment System is supplied with a monitoring syst to alert the owner to malfunclions. The tank is fitted with a liquid level detector which will warn of a pump malfunction. A pressure delector 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 An'audio ala'rm is inclu(Jed in the display unit. 3.2.6 PIP[ )RK Pipework used for the fabrication of lhe aeration system, sludge return and top level skimmer is in accordance wilh BS 3505:1986 Specification for unp/asticised po/yviny/ chloride (PVC-U) pressure pipes for cold potable water and relevant pads of BS 4346: Joints and fillings for use with unplasticised PVG pressure pipes. 4,1 ENVIRONMENTAL ASSESSMENT The treated waste water from a number of working installations has been comprehensively monitored for 2 years. The test results show that values stated for the parameters listed in Table 2 are consistently achievable over a range of operating conditions. 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 liveslock. 4.3 WATER PENETRATION The plant and tank witl~ 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 pad of routine maintenance the owner will 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. 5.1 CONDITIONS OF CERTIFICATION This Certificate is issued on behalf of the Irish Agr(~ment Board by the National Standards Authority of Ireland, NSAI, and shall remain valid so long as: 4.6.2 Safety of Syslem The Biocycle Waste Water Treament System has three alarms and provides for an air space or free board that is capable of accepting not less than an additional 2600 litres should the irrigation pump fail. This gives lwo to three days capacity in the average household, prior to the system overflowing. 4.7 TESTS AND ASSESSMENTS',WERE CARRIED OUT:,.'ro DETERMINE'" ...... -- Watertightness -- Strength of cover and frame assemblies -- Strength integrity and fibre content of concrete tanks · -- Hydrostatic assessment of the design of complete tanks for internal and external pressure loading -- Quality of treated effluent, 4.8 OTHER INVESTIGATIONS (i) Existing data on the history of use of previous installations.

The existing 1000 gallon septic tank is to be excavated, pumped, creushed, and abandoned in place. The existing leachfield is to be abandoned in place. Construction shall be in accordance with the approved site plan and design drawings, Municipal permit with any special provisions or conditions, and all applicable State and Municipal Wastewater Disposal Regulations. The contractor shall be responsible for obtaining any necessary underground utility locates. Unless specifically agreed otherwise, the property owner shall be responsible for final grading areas subsequently depressed from soil settling. On all leachfield mound systems, the property owner shall be responsible for ensuring a satisfactory vegetation growth over the mounded area. Contractors installing wastewater disposal systems must be certified by the Municipal Health Department for system installations. Owners installing their own systems must also receive prior approval from the Municipal Health Department. SEPTIC TANK INSTALLATION: A septic tank is to be constructed by a certified septic tank manufacturer. Construction sha].l include two 4" cleanouts for pumping access. The septic tank shall be sufficiently bedded to prevent settling or shifting of the tank. 17034 NORTH EAGLE RIVER LOOP · SUITE 204 o EAGLE RIVER, ALASKA99577 Page Two Lot 22, Block 2, Silvercrest S/D Ail standpipes on the septic tank shall extend a minimum of 12 inches above final grade· Septic tanks installed with less than 4 ft. of cover shall be insulated. A foundation cleanout shall be installed one to four feet from the building foundation. In the line between the tank and the leachfield there shall be two adjacent cleanouts (unless an effluent pumping system exists within the septic tank). These cleanouts shall be located on undisturbed soil not more than 10 ft. from the tank. The first cleanout, in line, shall be to clean toward the leachfield. The second cleanout shall be to clean toward the septic tank. Final grading over the septic tank shall be such that a positive slope exists away from the septic tank. PRESSURIZED MOUND SYSTEM INSTALLATION: 1. Any peat or organic matter must be removed from the elevated mound site. The bottom of the basal bed area as well as the top of the sand filter is to be within two inches of level. The distribution piping is to be of PVC (ASTM D3034 or equal). All joints are to be solvent cemented· The side slopes of the top layer of the mound system must not be steeper than 33% (3:1). The top of the mound shall be covered with a minimum of 6 inches of topsoil and vegetated sufficiently to prevent erosion. The distribution pipes are to be embedded in sewer rock. Care should be taken to backfill in such a way as to prevent damage to the piping system. Silt barrier material must be installed between the final gravel layer and the native soil backfill. Ensure the silt barrier covers the entire gravel surface before placing backfill. Page Three Lot 22, Block 2~ Silver?crest S/D Backfill over the final grave], layer must not be less than twenty-four (24) inches. Insulation must be installed when the backfill depth is less than thirty-six (36) inches° MINIMUM MATERIAL SPECIFICATIONS: Any septic tank proposed for installation must be constructed by a Municipally approved septic tank manufacturer. ?he following pipe materials are approved for use in septic system installations J.n the Municipality of Anchorage: Pipe Perforated Solid Cast Iron ASTM D3034 (PVC) ASTM FSI0 (HDPE) ASTM ])2662 (ABS) Yes Yes Yes Yes Yes No Yes Yes Use of a type of pipe other than listed above must be approved by the .ins?coting engineer~ Insular, ic.n shall be at least 2" thick extruded direct bu~;ial po].ystyrene (Dow Chemical Co~apany Styrofoam HI or equal[ ) .

Page Four Lot 22, Block 2~ Silvercrest S/D INSPECTIONS: Typically there will be a minimum of three (3) inspections required during the insta].lation of 'the wastewater disposal system. These inspections will occur as follows: The first inspection must be conducted after the excavation of ditches, pits, trenches, or beds and before the installation of any gravel. A septic tank may be set in place, but may not be backfilled before this inspection. The second inspection must be conducted after the placement of the silt barrier, gravel, distribution lines, standpipes, cleanouts, and insulation, but before the placement of any other backfill. The final inspection is to occur upon final grading of the property. Often there will be more than these 3 inspections required, Especially with the installation of multiple trenches, sand filters, pressurized distribution systems, etc. Thus, the inspecting engineer is to be contacted at ].east 24 hours prior to the start of construction. If necessary, a pre-construction meeting will take place on-site° The inspecting engineer will not coordinate, direct or control in any way the contractors activities. The owner shall contract ,~ith the contractor to perform the work outlined in these specifications and plans and in accordance with the attached M.O.A. permit. There will be no contractual arrangement existing between 'the contractor and S & S Engineering. S & S Engineering shall be the owner's representative and will inspect 'the work as stated above to document the contractors activities. Final acceptance of the contractors work rests with the owner and the M.O.A.

The scope of this project includes the installation of two five foot wide drainfields to serve the existing three bedroom residence on the referenced property. The existing 1000 gallon septic tank is to be excavated, pumped, crushed and abandoned in place. The existing leachfield is to be abandoned in place. 2. Construction shall be in accordance with the approved site plan and design drawings, Municipal permit with any special provisions or conditions, and all applicable State and Municipal Wastewater Disposal Regulations. 3. The contractor shall be responsible for obtaining any necessary underground utility locates. 4. Unless specifically agreed otherwise, the property owner shall be responsible for final grading areas subsequently depressed from soil settling. On all leachfield mound systems, the property owner shall be responsible for ensuring a satisfactory vegetation growth over the mounded area° 5. Contractors installing wastewater disposal systems must be certified by the Municipal Health Department for system installations. Owners installing their own systems must also receive prior approval from the Municipal Health Department. SKPTICTANK INSTALLATION: 1. A septic tank is to be constructed by a certified septic tank manufacturer. Construction shall include two 4" cleanouts for pumping access. 2. The septic tank shall be sufficiently bedded to prevent settling or shifting of the tank. 3. All standpipes on the septic tank shall extend a minimum of 12 inches above final grade. 4. Septic tanks installed with less than 4' of cover shall be insulated. Page Three 2. The following pipe materials are approved for use in septic system installations in the Municipality of Anchorage: ~ype of Pipe Perforated Solid Cast Iron Yes Yes ASTM D3034 (PVC) Yes Yes ASTM FS10 (HDPE) Yes No ASTM D2662 (ABS) Yes Yes Use of a type of pipe other than listed above must be approved by the inspecting engineer. 3. Insulation shall be at least 2" thick extruded direct burial polystyrene (Dow Chemical Company Styrofoam HI or equal). 4. Septic tank inlets and outlets shall be fitted with watertight couplings (Caulder, remco, or equal). A permeable nontoxic silt barrier (Typar 3401, Mirafi 140/N, or equal) must be installed between the final leachfield gravel layer and the native soil backfill. 6. Ail leachfield gravel (sewer rock) shall be 0.5"-2.5" screened gravel with less than 3% passing the %200 sieve. 7. When sand is being used as a filter material, its gradation specifications must conform to current M.O.A. or D.E.C. requirements. INSPECTIONS: Typically there will be a minimum of three (3) inspections required during the installation of the wastewater disposal system. These inspections will occur as follows: The first inspection must be conducted after the excavation of ditches, pits, trenches, or beds and before the installation of any gravel. A septic tank may be set in place, but may not be backfilled before this inspection. The second inspection must be conducted after the placement of the silt barrier, gravel, distribution lines, standpipes, cleanouts, and insulation, but before the placement of any other backfill. Page Four 3. The final inspection is to occur upon final grading of the property. Often there will be more than these 3 inspections required, especially with the installation of multiple trenches, sand filters, pressurized distribution systems, etc. Thus, the inspecting engineer is to be contacted at least 24 hours prior to the start of construction. If necessary, a pre-construction meeting will take place on-site. The inspecting engineer will not coordinate, direct or control in any way the contractor's activities.

Enclosed is a brief history of our involvement with thc BioCycle septic system located on the referenced property. Attached is a summary of expenses that wc have incurred duc to a mistake made by the Dcpartment of Health and Hmnan Services (D.H.H.S.) in issuing a permit to install the system and denying an approval of the septic inspection report after it was inslallcd in accordance with the apl)roved design. On November 17, 1994 a reqncst to issue a pernfit to upgrade tile septic system on tim referenced property was sent to the D.H.H.S. A permit was issued on December 1, 1994. The designed system was not inslalled at that lime. Ground water monitoring xvas performed the following spring and on iVlay 15,1995 groood water was fonnd to exist at 4 ft. below the ground surfacc. In a lctter daled Ma5' 24, 1995 a request was made to approve a design change tine to tile high gte]md water conditions that wcre found to exist. Then in a letter dated June 28, 1995, another design change was requested to install an innovative system, (BioCyclc). We were lead to believe by iha D.H.H.S. that a BioCycle would rcquire the lcachficld separation to ground water of 2 feet lust like the other innovative system being allowed at the time (i.e., intermittent sand filler). Wilb tile information provided to tile D.H.H.S. that grouod water was found 4 feet below tile ground surface. The Municipality of Anchorage re-issued rite pernfit #: SW 940441 to install the new system on September 7, 1995. Thc permit allowed the contractor to install the system 3 fect above the ground water table. The permit had the following special provisions. 1. The waste water disposal system installed under this pernfit is an alternative system mdcrgoing evaluation within the Monicipality of Anchorage. 17034 NORTIt EAGLE RIVER LOOP · SUITE 204 · EAGLE RIVER. AI~,SKA 99577 Page 2 Lot 22; Block 2; Silvercrcst SubdMsion November 20, 1997 Thc BioCycle system was installed on Scptember 26, 1995 ill accordance with thc Municipality of Anchorage approved permit. After the system had been iostalled and the inspection report submitted, S & S Enginecriug was inforlned that all approval would uot be issued unless we could obtain a letter of non-objectiou from the ADEC for the 3 feet separation distance to ground water. Tile D.H.H.S. indicated that tile requirenlent changed and reqnired S & S Engineering to address lhe problem created by the D.H.tt.S. A letter dated May 3, 1996 was sent to the ADEC requesting that a letter of non-objection be sent to tile D.H.H.S. for the vertical separation distance to ground water. The ADEC deuied the request on June 4, 1996. However, the ADEC was willing to reconsider our request providing the following information was addressed. 1. Verify ground water gradient. 2. Test water for coutaminaots. 3. Provide well logs. 4. Insitu soil logs. A second letter dated July 5, 1996 was seut to the ADEC after a significant amount of time and effort was expended by S & S Engineering providing the desired information. The second letter also requested a letter of non-objection of the separation distance between ground water and tile BioCycle system. The ADEC issued a second letter dated December 16, 1996 denying our request. The ADEC requested that we provide them wilh additional information. More research and site visits were performed to oblain the additiooal information requested by the ADEC. We prepared a tllird letter dated, Jannary 17, 1997 that was sent to the ADEC. The letter contained additional inforlnation that was requested. The ADEC again denied our reqnest iu a letter dated March 14, 1997. Au extensive search for information was then performed ill order to satisfy the requirements of ADEC. A final lelter was prepared ou July 3, 1997 and sent to the ADEC in an attempt to obtain a vertical separation waiver. A conditional approval of the reqnested vertical separation distance of 3 ft. frown tile bottom of tile soil absorptiou system to tile highest seasonal grouod water level was granted on August 11, 1997 subjec! lo two conditions. 1. Tile ground waler levels will need to be mooitored aunually at the site either dnring the nlonths of May or September when the ground water levels are likely to be at their highest level. If at aay time the grourtd water level to lhe boltonl of the system is less than 3 ft. the soil absorption system will need to be raised. 2. Annual monitoring resnlls of the affluent produce from tile BioCycle wasle waler trealment plant will need to be submitted to insure that it is operating properly. Page 3 Lot 22; Block 2; Silvercrest Subdivision November 20, 1997 Item #1, above, is not possible at this time since tile test bole groond water monitoring tube was removed at the time or system installation. Should this be required, we require payment advance from the Municipality of Anchorage to install a ground water monitoring robe aud expenses to lnonitor ground water iu the amount of $500.00. It is our contention that we would never have incurred tim cost of pursuing this waiver if tile MOA DHHS bad not issued a perlnit to install the system or bad approved the insl~ecfion report after the system bad beeu installed. We should have beeu advised of the requirement for a waiver or to provide additional sand separation prior to permit approval. We seek reiinbursement fi'om the Municipality of Anchorage and the Department of Health and Homart Services according to the attached summary of expenses and invoice #24907 for the total of $3,030.00.

Dear Mr. Cowan: This letter is in reference to the materials received in this office July 11, 1997, addressing this office's review comments regarding a request for a waiver of the required vertical separation distance between the bottom of an on-site wastewater disposal system and the highest seasonal groundwater level. The Department has completed its review of the submitted materials which included a cover letter addressing the previous comments by this office (letter dated 3/14/97), additional water samples analysis from surrounding wells, topographic map, and effluent analysis from the installed BioCycle wastewater treatment system. Based upon this review and previously submitted information the Department has the following comments: Vertical Separation Waiver Request: After careful review of all submitted information pertaining to the requested waiver for a vertical separation distance of three (3) feet from the required four feet as specified under State Wastewater Disposal Regulations (18 AAC 72.025(D)) it appears that most of the previous comments of this office have been addressed. Therefore, in accordance with 18 AAC 72.025(D) conditional approval of the requested vertical separation distance of three feet from the bottom of a soil absorption system to the high seasonal groundwater'level is granted subject to the following conditions: Ground water levels will need to be monitored annually at this site, either during the months of May or September when groundwater levels are likely to be at their highest level. If at anytime the groundwater level to the bottom of the system is less than three feet the soil absorption system will need to be raised. Mr. Robed Cowan 2 August 11, 1997 Annual monitoring results of the effluent produced from the BioCycle wastewater treatment plant will need to be submitted to ensure that it is operating properly. This approval does not imply the granting of additional authorizations nor does it obligate any other state, federal, or local regulatory body to grant required authorizations. Thank you for your cooperation with this Department, if there are any questions regarding the above, please do not hesitate to call.

I hope that we can agree that we have provided evidence in our previous letters that the water table below the ground surface nearly follows the ground contour. We believe that this evklence is provided through tile static water level of well logs provided you with our last letter. There was not a significant change in the static water level in tile property surrounding the reference property. However, there is a significant decrease in elevation between the properties located at the east compared to properties located on the north, south and west sides of the reference property. With the difference of elevation in ground surface and the static water level remaining approximately the same between the upper and lower lots provides us with evidence that the water table nearly follows the ground contour at the surface. We also understand the physical laws associated with tile gravitational forces and' realize that water will follow the course of least resistance. We believe that course is down gradient from the referenced property (see attached topo map). 17034 NORTH EAGLE RIVER LOOP · SUITE 204 · EAGLE RIVER, ALASKA 99577 Page 2 Lot 22; Block 2 Silver Crest Sub. 7200 Grover Drive Therefore we believe that tile only properties that may be effected by any contaminates entering into the ground water table from the BioCycle system could only effect the wells down slope from the system which includes Lot 1; Block 1; Nettleton Acres//3, and Lot 2A; Newby Subdivision. All other surrounding properties water system should not be effected by the bio-cycle drainage. Though it may be tree tbat water sample analysis from this area bas shown an increase in local concentration if nitrates, it is also trite tbat water samples history taken from snrrounding properties and a history show results of water testing for nitrates to be well below the water quality standard adopted by the State of Alaska and the Municipality of Anchorage of 10 mg/l. We obtained results of water samples and histories of snrrounding properties iii the area dating back to 1993 - 1996, with one test sample dating as far back as 1987. I have also takeu water samples from Lot 2A; Newby Subdivision and Lot I; Block 1; Nettleton Acres #3 within tile last 3 months to have tested. The nitrates levels for these properties bare returned at 2.3 and 3.5 respectively. I've obtaiued additional information from Gus Andress of BioCyclc Alaska· Mr. Andress provided ~ne with test salnple results taken by the Municipality of Anchorage Health and Human Services Water Quality Department. Tile test was performed on 5/12/97 aud the nitrate level was found to be well below the water quality staudards having nitrate percentage of .328 mg/l included in this letter are the results of water sample tests taken from this system, surrounding properties and similar bio-cycle systems installed in other locations. Mr. Andress also provided ns with copies of two letters written by representatives of the State of Alaska Department of Eavironmeatal Couservation- MatSu Public Service office. Tile letters suggest that the biocycle system consisteutly inet the state's secondary treatment standards and waiver request would appear to be supportable, We've also inclnded copies of tile letters sent to Mr. Andress by Alaska State Department of Environmental Conservation. With this additional information and the information in previous letters, we request that yonr department grant a three foot vertical separation waiver. Sincerely, · Robert C. Cowan, P.E.

Dear Mr. Cowan: This letter is in reference to the materials received in this office January 22, 1997, regarding a request for a waiver of the required vertical separation distance between the bottom of an on-site wastewater disposal system and the highest seasonal groundwater level. The Department has completed its review of the submitted materials which included a cover letter addressing this office's earlier review comments concerning groundwater gradient direction and the presence of nitrate contamination in groundwater wells in this area. Based upon this review and previously submitted information on file in this office the Department has the following comments: Vertical Separation Waiver Request: The requested waiver for a vertical separation distance of three (3) feet from the required four feet as specified under State Wastewater Disposal Regulations (18 AAC 72.015) is denied. After careful review of all submitted information it does not appear that the previous concerns outlined by this Department have been adequately addressed. With regards to the previous concerns the Department has the following comments wh'ich will need to be addressed further if this waiver is to be pursued further: Mr. Robert Cowan March 14, 1997 Page 2 A review of the surrounding well information provided does not confirm the groundwater gradient, it does verify that the individual lots appear to be drawing from the same aquifer. Additional information for the lots which are assumed downgradient (Lot 1, Block 1 Nettleton Acres No.3, and Lot 2A Newby Subdivision) would help to further define the groundwater gradient with respect to the location of the on-site wastewater disposal system on the subject lot. Recent water sample analysis from this area has shown an increase in local concentration of nitrate. The source of this nitrate is most likely the result of incomplete treatment of wastewater from surrounding on-site wastewater disposal system. Are there additional water sample analysis from the surrounding wells which can be examined by this Department as indicated in your last letter? Additional water samples for nitrate analysis from the lots downgradient of this lot would be beneficial for this review. In your letter of January 17, 1997, you indicate that the previously monitored seasonal high groundwater table which was found in May 1985, was the result of an unusually severe breakup. The conditions for an unusually severe breakup will need to be defined; the winter of 1994-95 did receive an above normal snowfall but that does not necessarily result in a severe breakup. If it is believed that groundwater will be found at this level the Department suggests that it be monitored during breakup of this year. While the Bio-Cycle does produce a more polished effluent than a conventional system there are still nitrates present at a concentration greater than allowed by water quality standards. Additional treatment to reduce the nitrates to meet those standards will better allow this Department to grant the requested three foot of vertical separation. Mr. Robert Cowan March 14, 1997 Page 3 Thank you for your cooperation with this Department, if there are any questions regarding the above, please do not hesitate to call.

The properties evaluated are located on a hillside that slopes moderately toward the west. The well logs of the surrounding properties provide evidence that the static water level in the wells have an average depth of approximately 79' ranging between 75' and 83' There is a slight increase of depth to the static water level on the uphill lots and a slight decrease on the downhill lots. The change of depth of the static water levels do not appear to be significant when compared to the contour of the ground surface. This provides us with additional evidence that the water table slopes down toward the west with a gradient that is very near to the contour of the ground surface. Ail wells on neighboring properties are located up hill from the leach field located on the referenced property with the exception of wells located on Lot 1 Block 1 Nettleton Acres ~3 and Lot 2A Newby Subdivision. There is no reasonable chance that the wells located on neighboring properties could be effected by contaminants from the bed system located on the referenced property. 17034 NC)RTH FAG[ E RIVER I ©©P ' SIJITE 204 · EAGI.E RIVER, Al ASKA 99577 Page 2 Lot 22; Block 2; Silver Crest Sub. January 17, 1997 The primary purpose of this letter is to request a letter of non-objection to the Municipality of Anchorage Dept. of Health and Human Services so that a waiver for a vertical separation to ground water can be issued by the Municipality. The distance to the previously monitored seasonal high ground water level is 3'. It is improbable that water exists now or will exist in the future at this shallow of a depth because it was measured during an unusually severe break up and the drainage pattern on the lot has been altered such that run off flows to the south rather than to the west (away from the leach field). Our review of water sample results in the immediate area of the referenced property indicate low levels of nitrate contamination in the water systems. At your request we can provide copies of these sample results. We therefore find no reason why a waiver cannot be issued and request a letter of non-objection. If additional information is required, please contact us. sincerely, Robert C. Cowan, P.E. RC/dn DEPT.

Both submittals note that a Bio-cycle unit was installed prior to the soil absorption system in question. I have reviewed the submitted information, this office's file on the above-referenced lot, and discussed this request with staff of the Municipality Of Anchorage, Department of Health and Human Services. There appears to be a discrepancy between the information that you provided to this office and what was requested in my June 4, 1996 letter.

The distance to the groundwater is 3 feet. In addition to the mitigating factors mentioned in our previous letter of May 3, 1996, we would also like you to consider the soils and static water levels found on the well logs (attached) of neighboring wells. The 3 feet of silty material above the groundwater would be of a slower percolation rate than 1.0 min/inch. With this in consideration and the workings of a Bio-cycle Unit this system would provide ample filtration before reaching the ground water. The water gradient ranges from 75 feet to 83 feet as shown on these well logs. Also attached is the well lo9:~;;.i:.:: and nitrate sample results from the well serving this property and a soils log performed prior to system installation, as you requested. It is our opinion the 'separation distance prescribed by 18 AAC72.020 is not required in this case. If you have any questions, please contact us. Sincerely, Robert C. Cowan, P.E.

Af*~,r the review of the submitted information, I can not issue the requested letter. The wastewate~" z.~lations (18 AAC 72) calls for a minimum of 4 feet vertical separation distance fi'om the botte'n of septic system to top of ground water.

The ~istance to the groundwater is 3 feet. ~he existing septic system (Bio-cycle Unit) was permitted by 9rror on September 7, 1995 by the MOA and installed on ~eptember 26, 1995. At that time, the system was designed for a 2 foot vertical separation to the groundwater· The mitigating factors involved which support the issuance of the waiver are as follows: The system which was installed is a Bio-cycle treatment system which produces a more polished effluent. The system was installed down gradient of the existing well. 3. There are no known nitrate problems in the area. 4. Drainage modifications while installing the system may have reduced the groundwater at the system's location. It is our opinion the separation distance prescribed by 18 AAC 72.02~ is not required in this case. If you have any questions, please contact us. Sincerely, Robert C.
