The approved separation distance is 55.0 feet. This is a reissuance of WR890071 for the new tank installed in 2012. This waiver approval applies to the existing septic tank only. Any future upgrade to the on-site wastewater disposal system will require all separation distances be met or another approval from this department. .................. 0 a a 0 E N ....................... ■ ............ a W M 0 N U ....... t 0 0 E 1 Waiver is Granted: X Waiver is not Granted: Date: �' // Approved by: -�PI6 Name of Reviewer **** VARIANCE/WAIVER REVIEW **** 0 1 TH I(M .

The tank was sited at the location of the previous septic tank, which was removed and decommissioned. The new tank replaced the old one. The existing trench was also installed at the same time and "as -built" by others. The original septic tank had an approved waiver at 55 -feet from the well, which was granted by MOA in 2004. The conditions for the waiver are essentially the same, the owners request that the septic tank installed in 2012 be allowed to remain at the 55 -foot approved waiver distance. A COSA inspection recently conducted demonstrates the septic system to be working adequately. Please reissue the waiver. The existing trench is over 100 -feet from the well.

Dear Mr. ~ Mrs. Hoffmann, A site assessment ~s performed on the referenced property involving on~ a burie~ underground ho~ h~ng f~ tank ~o~tnd on th~ w~id¢ of th~ ho~ adjacent to a p~vat~w~ in~$~d in a CMU ~. A fi~ pip~ and v~ pip~ w~r~ uisibl~ in th~ vi~t~ of th~ ~nk and th~ ground covar w~ par~a~ v~g~at~. Th~ wer~ no 4~ or p~ol~ odor~ d~d in t~ ~. Ther~ ~ appro~ 5" of fu~ r~ng in the bosom of th~ ~nk. Excavation w~ p~rformed with a 580 Case Backhoe operated under American Excava~t/ng. Excavation of the tank involved a (SW) w~ll graded ~andy ~oll. The tank was approximately 64" in diameter, length of 12' and a capacity of approximately 2,000 gallons. Soil ~amples were taken from the excavation after the tank had been removed. During and after excavation there were no petroleum odors detected or visible sign6 of tank l~akage. The tank was i~pected and v~ua~ly appeared to be in good condition. Soil 6~mples were taken at random from the bottom of the hole and along the sidewaY. The result6 of these tests indicated a TPH level of 172 ppm under EPA method 418.1 in the hole, a diesel product was verified under modified method 8015 and a TPH lev~ of 356 ppm under EPA method 418.1 from random 6~mpling of the pile. There were no BTEX or aromatic volat~e organic6 detected under EPA method 8020. The contractor ouer-cxcavated the hole at your direction along the 6ide~6 and the bottom. New 6oil samples were ~ken and checked with a PlO0 PID organic vapor meter and samples were 6ubm~tted to CHEMICAL AND GEOLOGICAL LABORATORIES for analysis under EPA method 418.1 for verification of .PID results. TPH 34.5 ppm were detected under laboratory analysts.

Hoffmann HC 78, Box 2340 Chugiak, Alaska 99567 Subject: Lot 120, T15N, R1W, Section 18 Dear Mr. and Mrs. Hoffmann: At the request of Mrs. Hoffmann, the department has reviewed all the information on file regarding the issuance of waivers, health authority application, and notice of violation on the above property which you own. We have found a number of inconsistencies and emissions which may have resulted in some confusion in handling your health authority approval. As a result, we will make the following adjustments to the record. These adjustments supercede any previous correspondence which you may have from our office. Waiver request #WR890071, granting a separation distance approval of 85 feet from your well to the absorption trench on Lot 119, is reinstated. Waiver request #WR890071, granting a separation distance approval of 90 feet from your well to the absorption trench on your lot, is reinstated. A re-evaluation of the separation distance from your well to your septic tank has shown that ADEC criteria for protection of your well have been met; therefore, you are granted a separation waiver to 55' You are not required to move the septic tank unless you wish to do so. The currently revoked Health Authority Certificate will remain disapproved until the fuel tank located approximately 10 feet from your well has been removed. After removal is accomplished, please have your engineer confirm this action in a report to this office. We will then be able to complete our review on the Health Authority application.

I apologize for any inconvenience this entire procedure may have caused for you, and want to thank you for allowing us to make s ' ultable corrections to the file.

WR #890071, PID #051-172-41, HA #890517 Dear Robbie, In response to your l~tter dated property, we wish to pursue item request wc previously submitted. February 9, 1990 on the referenced #2 as an alternative to th~ waiver Attached is a grid map (sc~e = I"-400') with the referenced property outlined in red. On this map we have shown dots to r~present the locations of several area w~lls for which w~ll logs are available. Next to each dot is the depth to a clay layer as indicated on the w~l logs. Also on the grid map we have transposed contour lines giving the topography of the area. In two locations where w~ data most available we have drawn a dashed lin~ and calculated the slope of the clay layer taking the area topography into consideration. One dashed line ~ to the south of the referenced property and the other is to the north. It appears the clay layer slopes from the east to the west at approximately 6.2% in the area south of the referenced property. It ~so appears the clay layer slop~ from the east to the west at approximat~y 13% in the ar~a north of the r~ferenced property. Therefore, within the referenced property, the confining clay layer se~ms to trav~ from the east to the west at a slope between 6.2% and 13%. This shows that the my layer (water table gradient) has a slope in excess of +39% away from th~ w~ll. With this additional information we request that you grant the referenced waivers from the w~ll on the property and the two encroaching leachfields with the following ~onditions: I. Th~ septic tank on Lot 120 is r~ocated 100 ft. from th~ w~ll.

S & S Engineering 17034 Eagle River Loop Road Suite 204 Eagle River, Alaska 99577 Subject: Waiver Request for T15N R1W Section 18 Lot 120 Waiver Request #WR890071, PID#051-172-41, HA# HA890517 Dear Mr. Shafer: Your request for waivers of separation distances between the on-site well and septic tank of 55 feet, the on-site well to absorption field to 90 feet and the on-site well to absorption field on the adjoining lot of 85 feet are denied. We believe that your request (reference your letter dated December 18, 1989) errantly transposed 10t number 120 and 119. By using the absolute optimum point allocation under ADEC guidelines, these requests fall far below the minimum required 16 points. Under no circumstance will a waiver be issued for the 55 foot separation between the well and septic tank on Lot 120 The alternatives to the alver request you submitted are as follows: 1. Relocation of the well on Lot 120 to a site outside al~l the required 100 foot setback distances, or; 2. Furnish data which establishes that the water table has a slope of at least +3% (away from the well) and relocate the septic tank on Lot 120. "Kids Are Our Future" Robert A. Shafer, S & S Engineering February 9, 1990 Page Two The issuance of the attendant Health Authority Approval will withheld pending satisfactory completion of the following: 1. be One of the above listed requirements has been satisfactorily completed and appropriate waivers issued by this office.

Also, without a well log and due to the scarcity of well logs for area, soil sorption and soil permeab~ty cannot even be estimated. And, since this is an artesian aquifer, the hydrau&ic gradient cannot be accurately ~compated, nor is it relavent. A nitrate mass ~alance model was not constructed since the systems have been in use for so long and one nitrate sample reset gives more information than an estimated nitrate model. Attached for your review are the following do~aments: I. A site plan showing the referenced well to septic separation distances. 2. A site plan showing the area-wide well and septic density. 3. Profiles between the referenced well and each septic system. 4. Copies of all available well logs for the area. $. Septic inspection reports for each septic system. 6.

HELL AND SEPTIC ADEQUACY TEST REPORT TEST DATE: December 5, 1989 LEGAL: Lot 120, T15N, R1W, LOCATION: Chugiak, Alaska RESIDENCE: WELL YIELD: PUMP YIELD: WATER SYSTEM: Sec.18 SEPTIC SYSTEM: Single Family, 3 Bedrooms +10.5 GallonB per Minute 10.5 Private Well From Municipal Records Tank: 1000 Gallons Absorption System: INSTALLATION DATE: 1977 INSTALLED ABSORPTION AREA: ORIGINAL SOIL RATING: Trench Type 24? Sq. Ft. 85 from original soil log report TEST PROCEDURE ~,~,~,~,~: The leachfield was filled with ~,~ater from an on-site well at an average rate of 2.3 GPM for a total of 540 gallons in 231 minutes. The septic tank and ]eachfield liquid levels were monitored referencing a measurement below the top of the standpipes. During the test, water was added through the trench cleanout tube and the ]eachfield water level was monitored as water was added and then absorbed into the surrounding soil, The water level in the septic tank did not rise during the addition of 540 gallons of water shewing that the leachffeld had accepted the entire amount. A total rise in liquid level in the leachffeld to the leach pipe level was recorded as 19". The monitor tube level was maintained at full capacity for the duration of the test establishing and average in flow rate of 2.3 GPM into the leach area. An additional +3480 gallons of water was then added at 2 GPM to confirm the inflow rate. Measurements were taken of the leachfield liquid level, after the test period with satisfactory reduction in liquid level. The monitoring indicates the septic system will accept the required 150 gallons per day of effluent, per bedroom, which is the required absorption rate for Municipal approval. Nell/Septic Adequacy Test Report Page 2 ~.& The well was pumped et a steady flow rate of 11.5 GPM. Total drawdown from a static water level of 7.2 feet was 30 feet after 30 minutes of pumping. At this point the water surface level in the well was static et 38 feet below the top of well casing. With the use of an electronic sonar, the yield rate of the well was monitored and calculated at a maximum rate of 11.5 GPM. This yield rate is the maximum rate that can be established by use o¢ the installed pump. TEST RESULTS The well yfeld or flow rate and septic system soil absorption rate meets the requirements of the Municipality of Anchorage for a 3 bedroom single family residence es of the day the system was tested. There are two separation distance waivers required for full Health Approval. Assessment of existing subsurface conditions by the inspecting engineer is limited to information obtained from the available monitoring tubes and Municipal record search. We do not guarantee the valldity or quality of subsurface tests and inspections performed by the original inspecting engineer or authority. This report is limited to absorption rate testing and surface separation measurements as currently required by the Municipality o¢ Anchorage and does not verify the fntegrfty of the pfpfng for the water supply or water quality other than the bacterial and nitrate content. The operational life and the matter of compliance with Mg.~,~,~R,,~,,,.,G~,~ for all water and septic systems depends on the local soil conditions, groundwater levels that may not be observed from the surface without additional testing, water usage of the homes being served by the system, and the detail of required testing procedure. Septic systems expire with use and future environmental concerns may require more extensive testing, which could render the leechffield unusable. This is true o¢ all septic systems. There is no guarantee that the well and septic system tested will meet the requirements for approval in the future. The test data and investfgatfon of existing conditions frs provided to our client for submittal to the Municipal Health Department for their review and approval. Any concerns with this test report should be discussed with the testing engineer. If it is requested we will submit the report directly to the Municipality.
