SKLH Consultants 1700 Vashon Circle Anchorage, Alaska 99515 Subject: Lot 22, Fairmont Subdivision, Waiver, Class C Public Water System, ans Wastewater Disposal System Approvals, Anchorage, Alaska, AWPSA Project Numbers 9621-DW-150-147 and 9621-WV-150-045; Review Dear Mr. Henslee: This letter is in response to your submittal received in this office on May 18, 1996 in which you requested two horizontal separation distance waivers, approval to operate a Class C Public Water System that was approved as a private water system and approval of the existing wastewater disposal system when the facility is upgraded to a duplex. I have completed my review of the submitted information and have the following comments. Waiver Reo_uests The limited on-site geological and hydro geological information, in itself, does not fully support the requested horizontal separation distance waivers. However, with the use of the Biocycle Package Treatment Plant that discharges a better treated wastewater to the subsurface soils, the requested waivers are reasonable. Therefore, in accordance with the provisions of the State Wastewater Disposal and Drinking Water Regulations (18 AAC 72.015 and 18 AAC 80.030), the following separation distances have been granted: Between the proposed Class C Public Water System Source Well and Biocycle Package Treatment Plant from 150 feet to approximately 124 feet. Steven Henslee 2 July 18, 1996 Between the proposed Class C Public Water System Source Well and Soil Absorption System from 150 feet to 1130 feet. This covers the effluent line from the Biocycle Package Treatment Plant to the existing soil absorption system. The above noted waivers are granted with the following requirements: The owner of existing package treatment plant will need to have a maintenance .agreement on file with this Department. The existing agreement is acceptable. However, a copy will need to be submitted to this office within 30 days after the facility has been changed from a single family home to a duplex. If the recorded nitrate levels are above 8 mg/I, a written report on what steps will be taken to determine the source of the contamination and to treat the water being provided to residents to ensure it is safe to drink will need to be submitted to this office. If total coliform bacteria counts increase with fecal bacteria being present, a written report on what steps will be taken to determine the source of the contamination and to treat the water provided to residents to ensure it is safe to drink will need to be submitted to this office. This waiver will remain valid until the wastewater disposal system on Lot 22 Fairmont Subdivision, Add. A requires upgrading or replaced or if the facility itself is modified. In addition, if the nitrate levels reach 10 mg/I or fecal coliform is detected without written approval of an action plan from this office will result in this waiver being invalid, Drinking Water In regards to the existing private water system that will be upgraded to a Class C Public Water system when the existing single family home is upgraded to a duplex. It appears that the existing system does meet all the existing State Drinking Water Regulations and guidelines now that the requested waivers have been granted. Therefore, final operation approval is being granted for the existing water system to operate as a Class C Public Water System. The Final Operation Approval, constitutes this approval, is enclosed. Steven Henslee 3 July 18, 1996 The Department is assigning Public Water System Identification (PWSID) Numbers to all public water systems in the State. The PWSID Number assigned to this public water system is 2'18507. At this time, State Drinking Water Regulations do not require owners of Class C Public Water Systems to submit routine monitoring results. However, due to the existing nitrate (as nitrogen) levels (2.3 mg/I) detected in the water, your clients will need to monitor the levels of total coliform bacteria and nitrates (as nitrogen) twice a year. The first sample should be taken between January 20 and April 1 with the second sample during late summer and early fall (July through September). Please provicle the longitude and latitude of the existing source well to this office as soon as possible. Wastewater DisDosal The information that you provided verified that the existing wastewater treatment and disposal system was approved by the Municipality of Anchorage. However, when this single family home is changed to a duplex, the volume of wastewater could increase due to the addition of another kitchen. As a result, before I can issue on-lot approval certificate, the following items will need to be addressed: A Property Owner Agreement allowing the Department of Environmental Conservation, Anchorage Western Public Service Area perpetual right of entry to the property during normal working hours will need to be submitted to this office. As we discussed, the use of the existing form that the Municipality of Anchorage uses will be acceptable. I have enclosed an example for your use. Verification, under your stamp as a Professional Engineer, that the existing wastewater treatment and disposal system will be able to handle the additional loading that could result from the change from a single family home to a duplex with two kitchens. These approvals and waivers do not imply granting of any additional authorizations, nor obligate any state, federal or local regulatory body to grant required authorizations. Steven Henslee 4 July 18, 1996 The fees that were calculated at the time of submittal are not complete. After completing my review of the submitted information I have determined that there should have been fees for two waivers, the public water system plan review, and the wastewater treatment and disposal system. The additional plan and waiver review fee is 475.50. The fee invoice (invoice number 203025) will be forwarded to your client. Since the original fee invoice did not include the fee reduction for a dual submittal, I took both fee reductions out of the new fee invoice total. Thank you for your cooperation with this Department. If you have any questions, please do not hesitate to contact me.

A Proposed Replacement Soil Absorption System 9513 Attached is a proposed design for a new replacement soil absorption system for the above referenced property. This design is being submitted in accordance with AMC Chapter 15.65. The proposed design will serve a 4-bedroom house and consists of a conventional bed absorption system for subsurface of treated wastewater coupled with a self-contained aerated treatment system. The Biocycle Treatment System is distributed by Pegasus Engineering of Anchorage, Alaska and is a self contained unit consisting of both primary and secondary treatment. Performance specifications are filed with On-Site Services. The property owners are aware this system is an innovative system currently being evaluated by the Municipality of Anchorage and ~s not full accepted at this time. Specific design and property information is provided below. SITE DESCRIPTION The topography of the subject property and neighboring lots generally consists of shallow surface slopes leading towards Little Rabbit Creek which borders the north property line. A steep ridge with slopes greater than 25% is present between the existing house and the creek and parallels the creek towards the northeast. The top of this ridge is roughly congruent with the north property line. This ridge line is limited in area and has no effect on the proposed design. The property is bordered on the west and east by undeveloped lots and immediately to the south by Ricky Road which is unconstructed. Continuing across DltttS, MOA, Alternative Design Submittal Lot 22 Fairmont Sub. Add. A, June 1995 (9213) -2- Ricky Road is the new south Anchorage Junior High School currently under construction. On 5-21 -95 three test holes were excavated with the purpose of finding a suitable area for a conventional wastewater disposal system. Two of the holes revealed soils unsuitable for a subsurface disposal field. A 5-foot layer of silt followed by a layer of yellow grey clay was found in TH-1. Similar material was encountered in TH-2 with the exception of a silty gravel layer. A blue-grey clay was found approximately 4.5 feet below the surface. Upon encountering clay, both excavations were terminated. Groundwater was not encountered in either test hole. Test hole three revealed substantially different soil and water conditions. Suitable soil for a subsurface disposal field is present in the upper portions of the test hole. A percolation test was performed on the receiving soil layer with a measured rate of 4.8 minutes per inch. Ground water was encountered approximately 7.5 feet below the surface. The water level was monitored for almost two weeks. The level remained constant for almost one week and then disappeared entirely. In addition to the three test holes just excavated, several other test holes were excavated in the past. Unfortunately, there is no information available on these excavations and, except for an existing monitor tube, no remaining evidence. The monitor tube does, however, reveal a static water level 3.5 feet below the surrounding ground surface. The level has been measured off and on several times over the past couple of years. This static condition is likely due to a perched condition. EXISTING HOLDING TANK There currently is a 2,000-gallon holding tank serving the property. This tank was installed in the mid 80's and was necessary because of limited useable area due to set back requirements from the existing water well, Little Rabbit Creek, and a small creek which ran diagonally across the southern half of the property from southeast to northwest. The creek course has changed from its past position and is now running along the alignment of Ricky Road. This alignment change has made available area which was not previously useable. The property owners wish to take advantage of this change and replace the holding tank with a conventional wastewater disposal system. The existing holding tank will be abandoned in place by pumping, liming, and crushing or backfilling with clean inert sand or dirt. BIOCYCLE TREATMENT SYSTEM On the basis of the suspected perched water table and the three test holes which indicate changing subsurface soil and water conditions, an alternative system is considered to be the most practical solution. Existing site conditions would require either a conventional shallow system design or a mounded absorption system. It has been my experience that such absorption systems have a limited useful life and, as such, provide only a temporary solution to the problem of domestic wastewater DHHS, MOA, Alternative Design Submittal I,ot 22 Fairmont Sub. Add. A, June 1995 (9213) -3- disposal. In addition, shallow systems require large plan areas to meet the required minimum absorption area generally considered acceptable. With the changing subsurface conditions encountered on this lot, it is possible to find unsuitable soil, impermeable layers, or ground water during construction. Given these limitations, the selected alternative maximizes the useful life of the shallow absorption field and minimizes the possibility of encountering changing conditions by using a smaller field size for the subsurface disposal of treated effluent after primary and secondary treatment has taken place using the Biocycle Treatment System. This system has been installed in a couple of areas in the Municipality of Anchorage with promising results. After consultation with the owners, they have selected the proposed design despite the Biocycle Treatment System still being in its evaluation phase and not being fully accepted by the Municipality of Anchorage at this time. SHALLOW ABSORPTION BED DESIGN Based upon the results of the percolation test, a conventional system design would require an application rate of 0.8 gpd/sf. Using this value, the minimum area required is 750 square feet of absorption area. A 15-ft wide bed system, therefore, must be at least 50 feet long. Using the Biocycle system a more liberal application rate is useable. Current intermit sand filter design guidelines indicate an application rate of 4.0 gpd/sf is acceptable for a percolation rate less than 30 mpi. Applying the same guideline to the Biocycle System, the bed can be minimized from an area of 750 s.f. to 150 s.f. A ]5-ft wide system then would only need to be 10 feet long. Although the subsurface soils meet the requirements for using an application rate of 4.0 gpd/s.f., this design uses a less ambitious rate of 2.0 gpd/s.f, leading to an area of 300 s.f. and field dimensions of 15' by 20'. Also, using this rate, should soils be encountered that are substantially different from the design soil layer, no additionally resizing would be required. An application rate of 2.0 gpd/s.f, is suitable for all soils with a percolation rate less than 60 mpi. This bed size was used for the submitted design.

A Proposed Replacement Soil Absorption System (9513) RECEIVED AUG 2 2 1995 Municip~lity of Anchorage Dept. Health & Hurn:Jn SerVices Dear Mr. Cross: Upon calling your office and speaking with one of your staff, my client was lead to belief that there was no apparent reason preventing the installation of a conventional soil absorption system on their lot and that a Biocycle system was not necessary. I understand this comment was made after reviewing the soil log and percolation test results for TH-3 submitted with the application. Although the percolation test would appear to indicate acceptable receiving soils for domestic wastewater are present, this test hole and percolation test are misleading when viewed as a stand alone document. When analyzed with other information submitted with the permit application, a clearer picture emerges regarding the subject property. Specifically, on the basis of other test holes and past explorations, it was my opinion the property has radically changing subsurface conditions with relatively small areas suitable for a soil absorption system, and those areas where a leach field could be installed would not be large enough for a conventionally sized system. The smallest such system is 750 square feet (15'x50~) and the largest system, for the poorest soil conditions, is 2000 square feet (20'x100'). As the size of the system increases, the likelihood of finding poorer soils requiring an increase in the system size or finding impermeable soils or shallow groundwater preventing the installation of the system all together grows. As a result of your staff's comment about easily installing a conventional absorption system, we decided to excavate an area equal in size to the smallest system which could be installed (15'x50'). The purpose was to evaluate the exposed subsurface conditions. On 9 August 1995, Carl's Excavating began digging the excavation. Excavation began at the farthest corner from TH-3. We immediately found a stiff yellow-grey clay DHHS, MOA, Alternative Design Supplemetat Information Lot 22 Fairmont Sub. ,Add: A, Aug 1995 (9513) - 2- ~ ~1 ~ I I I~1 ]1 I I ~ I I~11~ III ~111~1 ~" I ~ I I I ]~ i ~ ~ ~ I~ I~ ~ ~1 I1~ I ~111~ U ~ I IIII i I I I~ J unsuitable for a conventional absorption system. Excavation then began down along the perimeter of the long axis of the system. Better soils were encountered and some clean sand was found, however, it was only 14 inches thick and then disappeared after several feet. After the, sand, another area of clay was found which transitions into a sandy silt. It was at this point it became apparent that a conventionally sized system was not practical and ;~ 15'x20' area was excavated to verify there was sufficient room to construct a field for the Biocycle system. This excavation proved successful. The bottom of the excavation is 4.,3 feet above the water level measured in TH-3 and consists of silty sands and sandy silt, No percolation test was performed since the submitted Biocycle de:sign was sized for soils upto and including 60 minutes per inch. By inspection, the soil is not impermeable and a two-foot accepting strata was confirmed by hand excavating. On the basis of the soil conditions described above, it is my professional opinion the subsurface conditions underlying the subject property are unsuitable for a conventional soil absorption system; and that should a conventional system be installed its performance would most likely be marginal and its life span very limited necessitating a replacement system. We, therefore, ask that you consider our submittal request to install a Biocycle Treatment System, Attached is technical data for a pump we propose installing in the Biocycle system. Aisc, attached are head calculations indicating the proposed pump is suitable for the given condition:~. This pump is UL listed and is readily available in Anchorage meeting the requirements you set forth for non-pressurized distribution fields in our meeting of 1 August t!~5. Our original submittal letter is dated 27 June 1995 indicating the submittal has been in your office, a~iting approval, for almost 48 days as of today's date. We respectively request your prompt review and approval of our submittal, in light of the above information. If you should have any questions, please do not hesitate to contact me at 3~4-7096.

STATEMENT OF INSPECTION BY ENGINEER As certified by my seal affixed hereto and as of the validation date shown below, I verify that my investigation,based on procedures outlined in the Certificate of On-Site Systems Approval Guidelines for this application, shows that the on-site water supply and/or wastewater disposal system is(are)safe, functional and adequate for the number of bedrooms and type of structure indicated herein. I further verify that based on the information obtained from the Municipality of Anchorage files and from my investigation and inspection,the on-site water supply and/or wastewater disposal system is(are)in compliance with all applicable Municipal and State codes,ordinances,and regulations in effect at the time of installation. In conducting an adequacy test,I attempt to provide a thorough,conscientious engineering analysis of the system in accordance with MoA COSA guidelines and regulations.The reported results describe the performance of the system under the conditions encountered at the time of the test. and separation distances measured to readily identifiable features. The operational life of all wells and septic systems depend on the local soil condition,ground water levels that may fluctuate during the year,and the water usage of the family being served by the system.These conditions are outside the control of the evaluator of this system. All systems eventually fail and satisfactory test results do not guarantee future performance of the system,nor do they guarantee that there are no hidden defects or encroachments.Therefore we cannot provide any warranty for future performance, nor can we estimate remaining life of the system. The content of this report is for the sole benefit of the owner listed above. Name of Firm Pannone Engineering Services LLC Phone (907) 745-8200 Address P.O.

PES conducted an adequacy investigation on 1/10/2019 and added over 600 gallons of water to the drain field.The water levels in the drain field rose 8 inches, and then immediately began to a drop and returned to dry when the water was turned off(most likely the 8-inch rise was caused by hydraulic head from water being introduced into the system.) On average a 4-bedroom house will have 5 people living in it with an average waste water production of 50 gallons per day per person for a total of 250 gallons per day. We request a COSA approval for 3 bedroom/600gallons per day.When the current onsite system fails it will be replaced with an onsite system designed for 4 bedrooms. Granting this approval will not affect the health and safety of this lot or the surrounding lots now or in the future. If you have any questions or concerns, please contact me at 907.745.8200.

In the modifications of the State Drinking Water Regulations that were finalized on October 1, 1999, water systems serving duplexes were reclassified. In this regulation change, water systems serving duplexes were reclassified from Class C public water systems to private water systems. Due to this reclassification all water systems serving duplexes found in the Drinking Water and Wastewater (DW/WW) Program database will be placed in delete status. All information will be kept in the DW/WW Program hard files. As a result, the above referenced property has been placed in delete status in the DW/WW Program database. Operation approval was not found in file. Cc: Jamie Stazel, ADEC, DW/WW Program ' � '� Alt iicipality of Anchorage ., a \k Department of Health and Human. Services 825 "L" Street Rick Mystrom. P.O. Box 196650 Anchorage, Alaska 99519-6650 Mayor Dear Homeowner/Prospective Buyer: The on-site wastewater disposal you are interested in purchasing is an "altemative" wastewater disposal system. This system, known as a "Biocycle Aerated Wastewater Treatment System", is undergoing testing within the Municipality of Anchorage under the Alternative System section of the Wastewater Disposal Regulations (AMC 15.65). There are certain risks involved with the ownership of one of these systems: This system has been shown to be effective in other areas. The system is currently undergoing a two year testing period in Anchorage wider the guidance of the Department of Health and Human Services (DHHS) and the State of Alaska Department of Environmental Conservation (ADEC) to determine its effectiveness in a subarctic environment. Testing results on systems installed in 1994 have been very encouraging. Copies of initial test results are available from the DHHS. 2. The Biocycle system has not been tested and approved by the National Sanitation Foundation (NSF). Currently, Anchorage Municipal Code for Wastewater Disposal Regulations requires proprietary equipment to have NSF approval. This approval or changes to the Wastewater Disposal Regulations through Municipal Assembly action will be necessary prior to this system being approved as a standard system. 3, The "Biocycle" system for this property may have received vertical separation distance waivers from both State of Alaska and Anchorage Municipal Codes to both ground water and bedrock. These waivers were granted due to the system's expected performance withal the site conditions on this property. If the test results do not support these waivers, modification or replacement of this system may be required. 4. If this system fails to meet the requirements set for it to become a standard, code approved wastewater disposal system, it may have to be removed and replaced by either a holding tank or (if possible) other wastewater disposal system that meets Municipality of Anchorage requirements. The cost of any conversions required to meet code requirements will be the responsibility of the homeowner at the time of conversion.

TONY KNOWLES, GOVERNOR (907) 269-7505 SUBJECT: Lot 22, Fairmount S/D Addition No. A; Class "C" Public Water System, Setpic System, PWSID NO.218531, AWPSA Project No. 9736-02-01-WJ-033 Dear Mr. Johnston: This letter is in response to the information received in this office June 23, 1997, requesting a letter of compliance of the above on-site public water and wastewater disposal systems for the purpose of a bank loan certification. The Department has completed its review of the submitted information which included septic system adequacy test, Application for On -Site Water and Sewer System Approval, and recent water sample analyses for total coliform bacteria and inorganics for nitrate. Since this drinking water system has been previously approved and because it serves less than 13 bedrooms or 25 residents, this water system is viewed as a Class "C" Public Water System. Assuming that there have been no modifications to the water system since approval was granted, verification that the water supply has been recently tested will be required to maintain compliance with State Drinking Water Regulations (18 AAC 80). The submitted water analyses were satisfactory for both total coliform bacteria and nitrate and satisfy this concern. Therefore, for the concerns of this Department, this water system is in compliance with State of Alaska Drinking Water Regulations (18 AAC 80). A review of the information on file indicates that this system been previously approved for construction and operation by this Department. Based upon the recently conducted septic system adequacy test performed June 20, 1997, it appears that on the day of the test the system was accepting the wastewater loading for which it was designed. Therefore, assuming that there have been no modifications to the system, the wastewater disposal system is in compliance with State of Alaska Wastewater Disposal Regulations (18 AAC 72). Attached is an "Public Health Authority Approval for On -Site Drinking Water and Sewer Systems" certificate verifying this property's status having approved water and wastewater disposal systems that are in compliance with both 18 AAC 80.300, and 18 AAC 72.200. Mr. Johnston 2 June 25, 1997 Please reference the following public water system identification number (PWSID No. 218507) when submitting future water samples so that this system can be properly credited. Thank you for your cooperation and coordination with this Department, if there are any questions regarding the above please do not hesitate to call. Sincerely, f Michael Lu, E.I. .

A Well Waiver Submittal for Proposed Class C Well 9518 Dear Mr. Klewano: This letter is to request a waiver for a separation distance less than that set out in 18 AAC 80.030 for a proposed Class C water supply well serving the subject lot. As shown on the attached plot view, appendix A, the well is located approximately 124 feet from the septic tank/treatment system and approximately 130 feet from the leach field. The owner, requests a waiver to allow the existing separation distances remain as is rather than relocate the existing well. The subject well was drilled August 1982. The existing septic treatment system was installed in August 1995. The well presently serves a 4 -bedroom single family residence. The property is zoned for multi -family and may be converted into a duplex in the immediate future, thus changing the status of the well from a private well to a Class C system. The well is 300 feet deep and consists of 191 feet of six-inch diameter steel casing covered with a sanitary well seal. The casing extends more than 12 -inches above the surrounding ground surface. The site surface drainage characteristics are good. The well casing has yet to be grouted. The septic system consists of a self contained Biocycle aerobic treatment system and a 15'x 25' absorption field. The system was installed August 1995 under an alternative system permit issued by the Municipality of Anchorage as part of an ongoing evaluation program which is scheduled for final evaluation in October 1996. The system is maintained by Pegasus Engineering (333-1608, Gus Andrees) under a maintenance agreement with the property owner. SKLH Consultants/Mr. Ke- Klewano, ADEC Lot 22 Fairmont Sub. Add. .., Class C Well Waiver Sub. May 1996. 9518. Page 2 A copy of the permit and maintenance agreement and the original system design submittal to the MOA has been attached for reference in appendix B. A. REQUEST FOUNDATION This waiver request is being submitted to allow the existing conditions to remain as is since the subsurface conditions do not lend themselves to relocating the existing treatment system or leach field. Attached is a copy of the subsurface exploration performed in the summer of 1995 during the design and construction of the existing soil absorption system. This exploration shows the subsurface conditions are poor to unacceptable for on-site absorptions systems. In fact, the installation of the existing system was made possible only because of the exceptionally clean effluent produced by the aerobic treatment system (Biocycle System). The cleaner effluent allowed a substantial reduction in the size of the absorption field. Every attempt was made to locate the absorption field and treatment system as far from the existing well as possible. Existing topographic and development constraints restricted the placement of the Biocycle system and unsuitable subsurface conditions restricted the location of the absorption field. B. SUBSURFACE CONDITIONS Subsurface Soil Conditions. In general, the immediate soil stratas (surface to 12 feet below the surface) consist of silts and clays with very limited areas of coarse or fine sand overlying bedrock. Mineralized soil becomes more common and the depth to bedrock appears to increase north of Little Rabbit Creek as indicated by test holes excavated on lot 12 of Fairmont Subdivision. Beyond 12 feet below the ground surface bedrock is continuous to the maximum depths penetrated by wells. At the well serving the subject lot bedrock is found from nine feet to 297 feet and on lot 12 from ten feet to 345 feet. The difference in ground elevation between the two wells is estimated at approximately 50 feet or more. Although the property immediately east of lot 12 is developed, there is no available information regarding the existing well or septic system. 2. Groundwater Conditions Groundwater appears to be discontinuous over the property. Groundwater may be found from immediately beneath the surface to no water at all in test holes which are less than 100 feet apart. On the basis of previous test hole excavations, groundwater conditions where they exist are relatively shallow, from slightly beneath the surface to eight feet or greater. The gradient of SKLH Consultants/Mr. Ker iKlewano, ADEC Lot 22 Fairmont Sub. Add. ., Class C Well Waiver Sub. May 1996. 9518. Page 3 the groundwater varies, but appears to follow the existing ground contours flowing towards Little Rabbit Creek. Some perched groundwater has been found which is expected based upon the extensive presence of subsurface silts and clays. The groundwater encountered near the ground surface is not suspected to part of an aquifer system, but would appear to consist of localized surface water drainage (rainfall and snow melt, etc.) filtering through the immediate soil stratas and running along the bedrock surface. In addition, on the basis of well logs, it does not appear to be hydraulically connected to the underlying aquifer from which the wells draw potable water. Due to varying subsurface soil conditions, the seasonal high water table is estimated to be from the surface to any depth depending upon the underlying soil conditions. C. EXISTING WATER SUPPLY SYSTEM The existing water system is comprised of the existing well and a separate storage and delivery system. A schematic of the system has been attached for your convenience as part of appendix C. The system consists of a 300 -gallon polyethylene potable water storage tank followed by a booster pump capable of delivering 24 gallons per minute at 30 psig to the house distribution system. A Class C check list and detailed design submittal are also attached in appendix C. Due to peak demand needs being supplied by the storage tank and booster pump, a four-hour flow test and 20 minute peak well flow test were not performed or considered necessary. Due to the depth of the well and the depth to the static water level, no water level measurement has been taken. D. LIMITING THE POTENTIAL FOR WATER CONTAMINATION Although the treatment system and the leach field are within the well's 150 -ft protective radius the system poses less threat to the existing well than a conventional wastewater treatment system. The manufacture, design, and quality of effluent of the Biocycle system all contribute to reduce or eliminate the potential for water contamination. a. Manufacture The Biocycle system is a self contained fiberglass anaerobic and aerobic treatment system with only two penetrations; a 4 -inch inlet pipe and a 1.5 -inch pressurized discharge line. Both penetrations are above the working liquid level of the system and were also sealed against SKLH Consultants/Mr. Kep• �irlewano, ADEC Lot 22 Fairmont Sub. Add. ., Class C Well Waiver Sub. May 1996. 9518. Page 4 liquid and moisture. The exterior of the unit is completely encased in 3 inches of spray on polyurethane insulation and was placed on a bed of fine gravel and backfilled with fine gravel to reduce the possibility of punctures. In addition, the system is monitored monthly for operation and changes in water elevation which would indicate a leak. Access to the system for maintenance and monitoring is through an aboveground locking manhole. b. Design The pressurized discharge line is a solid line with only two joints between the Biocycle system and the leach field. The first joint is a glued reduction fitting from 1.5 inches to 1 inch approximately 10 feet outside the treatment system and the second is a glued joint at the leach field where the force main transitions to the header pipe. Between these two joints the force main is a solid length of unjointed HDPE. The line was bedded with imported bedding material for reducing the possibility of damage and leaks. The line is sloped to drain effluent back to the Biocycle system between pumping events. Effluent Quality Since the Biocycle system is an aerobic treatment system providing secondary treatment, the quality of the effluent substantially exceeds the effluent introduced to subsurface soils by a conventional wastewater system. Treated effluent is equivalent to that produced by recirculating sand filters (RSF) which have been adopted by the Municipality of Anchorage as a conventional treatment system. Use of a RSF allows for a reduction in the separation distance between the seasonal high groundwater level from four feet to two feet and from impermeable soil layers or bedrock from six feet to four feet. A typical effluent analysis for the subject Biocycle system is below. Total Kjeldahl Nitrogen ................................................. 16.0 mg/1 Nitrate-N...................................................................... 16.5 mg/1 Total Suspended Solids ................................................. 13.0 mg/l Biochemical Oxygen Demand ......................................... 19.0 mg/1 Fecal Coliform.......................................................... 38,000 mg/1 Considering the protective radius distance was established from studies of conventional wastewater treatment systems, i.e., primary treatment only using a septic tank, the quality of effluent produced by this system alone should justify some reduction of the required separation distance.

CONCLUSION AND RECOMMENDATION On the basis of the above information it is my professional opinion the requested reductions in the regulatory separation distance between the proposed public water well and the existing domestic wastewater treatment system do not pose an increase threat to the well or the public health. Therefore, I recommend the proposed waivers between the well and the Biocycle treatment system and between the well and the leach field be granted.

A Class C Public Water System Design Submittal. 9518 Dear Mr. Klewano: The owners of the above referenced property wish to upgrade their existing private well to a Class C public well. The existing residence is in the process of being converted from a single family residence to multi -family (duplex). The existing private water system as outlined in included design calculations currently meets or exceeds the design requirements for a Class C system and should not require additional construction. A plan drawing is attached. The existing system consists of the following components: a. Six-inch well 300 feet deep and a yield of 1 gpm. The casing extends more than 12 inches above the ground level and surface drainage slopes away from the well. The well is currently not grouted, but is scheduled for grouting this spring once the ground has thawed. b. Existing well pump make and model is unknown, but believed to be 1/2 -hp pump. c. Aboveground storage consists of approximately 326 gallons and is made up of a 300 -gallon storage tank and two pressure tanks; a Well -X -Troll WX-250 and a non -bladder steel pressure tank. The steel tank is 16" x 48" for a computed total volume of approximately 42 gallons with an estimated storage volume of 12.5 gallons. (E = 30% d. Aeromotor SJ -56 1/2 -horse -power jet pump drawing from the 300 -gallon storage tank. This pump pressurizes the distribution system and pressure tanks.

DESIGN PARAMETERS (Refer to ADEC's Suggested Practice for Small Water Systems. ) A. Peak Demand... 16 gpm. Use eight gallons per minute per unit. Design peak demand, therefore, for duplex unit is 16 gpm total. B. Peak Volume... 320 gallons Duration of peak demand is 20 minutes. Sixteen gpm @ 20 minutes = 320 gallons. C. Total Dynamic Head... NA The well and well pump have no peak flow requirement since they serve to fill the 300 -gallon storage tank. Total head is supplied to the distribution system by a separate booster pump after the storage tank. The only head loss between the pump and the pressure tanks is from minor pipe losses. Headlosses experienced by the system are from losses in the internal distribution system in the house plumbing after the pressure tanks. II. SYSTEM DESIGN & COMPONENTS A. Existing Pump... Aeromotor SJ -56, 1/2 hp The existing Aeromotor pump provides the design flow of 16 gpm up to an internal system head of 98 feet. Internal system heads, less than 98 feet, allow for substantially higher peak flow rates. A flow chart for the existing Aeromotor jet pump is attached. The attached pump chart does not include flow for zero lift conditions nor for conditions where there is not only no lift, but conditions where the hydraulic grade line is above the pump inlet as exits here (see system plan drawing).

This chart has been extrapolated from the attached manufacture's pump chart. Sixteen gpm occurs at 42.3 psi. B. Existing Water Storage... 300 -gallon Norwesco Vertical Polyethylene Storage Tank SKLH Consultants/Mr. Keevir 7 wano, ADEC Lot 22 Fairmont Add. A. Clas. Design Submittal 18 March 1996, 9518, Page 3 the required water storage is provided by a 300 -gallon vertical polyethylene storage tank (92%). This tank is at atmospheric pressure. Manufacture's information on the tank has been attached. These tanks are approved for potable water storage. The remainder of the required storage is provided by the two existing storage tanks. The combined computed storage of the system is 326 gallons, slightly more than the required volume of 320 gallons. B. Existing Pressure Tanks... WX-250 and Generic Steel Tank There are two existing pressure tanks serving the system and connected in series. Attached is a Weil-X-Trol guideline for sizing pressure tanks. The guideline indicates the WX-250 is almost sufficient alone to serve the system. The second tank provides redundancy and storage to meet peak storage demand. Pressure setting range is 30 - 50 psig. C. Existing Water Line from Well The existing water line is 3/4 -in. copper. Based upon the depth of the pitless adapter at the well, the depth of burial meets the minimum depth of 10 feet. 9609 LOT 22 ,FAIRMONT SUB, ADD A.

A Proposed Replacement Soil Absorption System 9513 Attached is a proposed design for a new replacement soil absorption system for the above referenced property. This design is being submitted in accordance with AMC Chapter 15.65. The proposed design will serve a 4 -bedroom house and consists of a conventional bed absorption system for subsurface o'Ytreated wastewater coupled with a self-contained aerated treatment system. The Biocycle Treatment System is distributed by Pegasus Engineering of Anchorage, Alaska and is a self contained unit consisting of both primary and secondary treatment. Performance specifications are filed with On -Ste Services. The property owners are aware this system is an innovative system currently being evaluated by the Municipality of Anchorage and is not full accepted at this time. Specific design and property information is provided below. SITE DESCRIPTION The topography of the subject property and neighboring lots generally consists of shallow surface slopes leaning towards Little Rabbit Creek which borders the north property line. A steep ridge with slopes greater than 25% is present between the existing house and the creek and parallels the creek towards the northeast. The top of this ridge is roughly congruent with the north property line. This ridge line is limited in area and has no effect on the proposed design. The property is bordered on the west and east by undeveloped lots and immediately to the south by Ricky Road which is unconstructed. Continuing across DHHS, MOA, Alternative Design SubnjitW Lot 22 Fairmont Sub. Add. A, Junc 1995 (9213) .2 - Ricky 2 - Ricky Road is the new south Anchorage Junior High School currently under construction, On 5-21-95 three test holes were excavated with the purpose of finding a suitable area for a conventional wastewater disposal system. Two of the holes revealed soils unsuitable for a subsurface disposal field. A 5 -foot layer of silt followed by a layer of yellow grey clay was found in TH-1. Similar material was encountered in TH-2 with the exception of a silty gravel layer. A blue -grey clay was found approximately 4.5 feet below the surface. Upon encountering clay, both excavations were terminated. Groundwater was not encountered in either test hole. Test hole three revealed substantially different soil and water conditions. Suitable soil for a subsurface disposal field is present in the upper portions of the test hole. A percolation test was performed on the receiving soil layer with a measured rate of 4.8 minutes per inch. Ground water was encountered approximately 7.5 feet below the surface. The water level was monitored for almost two weeks. The level remained constant for almost one week and then disappeared entirely. In addition to the three test holes just excavated, several other test holes were excavated in the past. Unfortunately, there is no information available on these excavations and, except for an existing monitor tube, no remaining evidence. The monitor tube does, however, reveal a static water level 3.5 feet below the surrounding ground surface. The level has been measured off and on several times over the past couple of years. This static condition is likely due to a perched condition. EXISTING HOLDING TANK There currently is a 2,000 -gallon holding tank serving the property. This tank was installed in the mid 80's and was necessary because of limited useable area due to set back requirements from the existing water well, Little Rabbit Creek, and a small creek which ran diagonally across the southern half of the property from southeast to northwest. The creek course has changed from its past position and is now running along the alignment of Ricky Road. This alignment change has made available area which was not previously useable. The property owners wish to take advantage of this change and replace the holding tank with a conventional wastewater disposal system. The existing holding tank will be abandoned in place by pumping, liming, and crushing or backfilling with clean inert sand or dirt. BIOCYCLE TREATMENT SYSTEM On the basis of the suspected perched water table and the three test holes which indicate changing subsurface soil and water conditions, an alternative system is considered to be the most practical solution. Existing site conditions would require either a conventional shallow system design or a mounded absorption system. It has been my experience that such absorption systems have a limited useful life and, as such, provide only a temporary solution to the problem of domestic wastewater DHHS, MOA, Alternative Design Submittal Lot 22 Fainnont Sub. Add. A, June 1995 (9213) -3- disposal. 3 - disposal. In addition, shallow systems require large plan areas to meet the required minimum absorption area generally considered acceptable. With the changing subsurface conditions encountered on this lot, it is possible to find unsuitable soil, impermeable layers, or ground water during construction. Given these limitations, the selected alternative maximizes the useful life of the shallow absorption field and minimizes the possibility of'encountering changing conditions by using a smaller field size for the subsurface disposal of treated effluent after, primary and secondary treatment has taken place using the Biocycle Treatment System. This system has been installed in a couple of areas in the Municipality of Anchorage with promising results, After consultation with the owners, they have selected the proposed design despite the Biocycle Treatment System still being in its evaluation phase and not being fully accepted by the Municipality of Anchorage at this time. SHALLOW ABSORPTION BED DESIGN Based upon the results of the percolation test, a conventional system design would require an application rate of 0.8 gpdi/sf. Using this value, the minimum area required is 750 square feet of absorption area. A 15 -ft wide bed system, therefore, must be at least 50 feet long. Using the Biocycle system a more liberal application rate is useable. Current intermit sand filter design guidelines indicate -an application' rate of 4.0 gpd/sf is acceptable for a percolation rate less than 30 mpi. Applying the same guideline to the Biocycle System, the bed can be minimized from an area of 750 s.f. to 150 s.f. A 15 -ft wide system then would only need to be 10 feet long. Although the subsurface soils meet the requirements for using an application rate of 4.0 gpd/s.f., this design uses a less ambitious rate of 2.0 gpd/s.f. leading to an area of 300 s.f. and field dimensions of 15' by 20'. Also, using this rate, should soils be encountered that are substantially different from the design soil layer, no additionally resizing would be required. An application rate of 2.0 gpd/s.f. is suitable for all soils with a percolation rate less than 60 mpi. This bed size was used for the submitted design.
