This letter issues a Conditional Separation Distance Waiver for the requested reduction of the State’s minimum separation distance requirement between drinking water wells and sanitary sewer components, as detailed in the submitted engineering information and outlined below. Project Description This property is located on Shorecrest Drive and backs up to the bluff along Turnagain Arm. Many lots in this area are served by the Sand Lake Services Public Water System, PWSID 210485, or other drinking water wells, and they have individual sewer systems, typically onsite septic tanks and drainfields. Two of Sand Lake PWS’s groundwater wells are nearby (Wells #1 and #3). The majority of Lot 22 is within the 200 foot protection radius around both wells. The only portion outside of 200ft is the steep bluff dropoff to the coastline. Well #1 – Drilled May 9, 1964 to a total depth of about 212 feet. Cased to 206 feet. Well #3 – Completed February 11, 1995. The well log (WELTS #23107) shows it was grouted, and that it was cased to 525 feet with the intake screen starting at 513 feet. The submitted sanitary sewer design (dated 4/5/2022) for this property now proposes to install a Category III Advantex septic tank along with an appropriately designed trench drainfield, no closer than 120 feet to the Sand Lake PWS wells. Components include: - Septic tank: 1,500-gallon Advantex FAP (fully assembled package) two-compartment fiberglass tank with AX20 filter pod - Drainfield: 7-foot effective depth absorption trench system (11 feet long by 3 feet wide, designed for 4 gpd/sf) o Space for a backup disposal field is available >14ft away, towards the bluff - System is designed for a 4-bedroom or less single family residence, with 600 gal/day maximum daily flow Seacliff S/D, Block 1, Lot 22A 4/19/2022 220419 Seacliff SD_Block1_Lot22A Updated Waiver Sand_Lake_210485 WA.docx Page 2 of 3 - All gravity piping from the residence (aka private sewer line) is expected to meet its required separation distance of 100 feet from both wells. Separation Distance Waiver The separation distance encroachment was reviewed based on the following elements to maintain public safety:  Confined Aquifer: Layers of clay or silt can act as confining layers, which can help prevent contamination from reaching the water. The aquifers that these wells access appear to be confined.  Well #1 was drilled through clayey silt from ~72 to 180 feet below ground surface (bgs), according to the soils log.  Well #3 has layers of clay and/or silt from 335-392, 401-432, and 457-478 feet bgs, and a static water level of 53ft bgs according to the well log.  Ground slope: The ground generally slopes away from the wells towards the midpoint of Lot 22. As the property approaches the bluff, there is an increase in elevation. However, groundwater flow through this area is still generally away from the well and towards the coast.  Nitrates: Trends of increasing nitrates can indicate failure of any nearby septic systems. Nitrate samples for Sand Lake PWS 210485 are available from 1993 to the present, and indicate very low levels, typically around 0.2 mg/L.  If operated and maintained correctly, any effluent that passes through this system will be treated to a higher degree than that of the conventional septic system previously approved March 23, 2021, further decreasing the chances of fecal contamination. Based on an evaluation of the available information and endorsement of the submitting engineers, a Separation Distance Waiver to 120 feet for the onsite sanitary sewer components outlined above is issued in accordance with the State’s Drinking Water regulations, 18 Alaska Administrative Code (AAC) 80. Please forward any record drawings and documentation of construction to this office once completed. The separation distance encroachment is approved with the following conditions:  The wastewater system must be installed by a person that meets the requirements of 18 AAC 72.015.  The sewage system must be maintained in accordance with State of Alaska and Municipality of Anchorage requirements for as long as the system is in operation. The lot owner or their Authorized Service Provider should keep all records, such as installation records, septic tank maintenance, inspections, and pumping, and have them available on request. For additional information, see the following:  https://dec.alaska.gov/water/wastewater/engineering/maintain-septic  https://www.muni.org/Departments/OCPD/development-services/wells-septic  Any changes, constructed or natural, may void this waiver and the sewer may be required to be relocated.

Occurrences of floods, earthquakes, and human activity can change the geophysical, chemical, and biological conditions under which this determination was made. This determination does not preclude the Department from reevaluating this separation distance waiver in the event such conditions change or additional information becomes available to the Department that would warrant further review. Approval of this waiver does not obligate the department to approve future waiver requests proposing the same design, is not an approval of omissions or oversights, and does not guarantee correctness of the functional design or waive the owner’s responsibility for continued compliance with state, federal, and local regulations. Informal Reviews and Adjudicatory Hearings A person authorized under a provision of 18 AAC 15 may request an informal review of a contested decision by the Division Director in accordance with 18 AAC 15.185 and/or an adjudicatory hearing in accordance with 18 AAC 15.195 - 18 AAC 15.340. See DEC’s “Appeal a DEC Decision” web page https://dec.alaska.gov/commish/review-guidance/ for access to the required forms and guidance on the appeal process.

We would like to apply for a permit renewal. In addition to this, we were sent a revised as-built of the building footprint, which prevents the septic tank from being placed in the location on the original permit. We have revised the layout to fit in the tank, trench, and alternate site in the space that is left without encroaching on the well more than the existing waivers allow. Due to the placement of the home, we are unable to achieve 10’ separation from the building footprint as well as from the property line. For this reason, we are asking for a waiver to allow the existing and alternate trenches to be located 1’ from the west property line. This location will not affect neighboring septic, which is on the other side of the lot, and there is no neighboring well. While the soil is sandy, construction will done with equipment that will not create a pit or undermine the neighboring property. There are no other options that will not further encroach on the well, but granting this waiver will not adversely affect this property or the neighboring property.

Learn why this -is-important 1 CAUTION: This email originated from outside the State of Alaska mail system. Do not click links or open attachments unless you recognize the sender and know the content is safe. Hello Darlene, In 2021, a waiver was granted between a public water system and a proposed septic system on a vacant lot (Seacliff Block 1 Lot 22A). The owners sold the property and the new owners have hired a different engineer to design a septic system. I have attached the waiver and original septic design, as well as the new proposed design. Does the new owner/engineer need to resubmit for the waiver? They are designing based on the 120 ft waiver granted in 2021 and are proposing an advanced wastewater treatment system. The waiver grants a conditional approval. What are the conditions that have to be satisfied to be given full approval? Do you just need to see the record drawing/as-built survey after installation to verify that they didn't end up installing it closer? Also, the letter states that the wastewater system must be installed by a person that meets the requirements of 18 AAC 72.015. All wastewater systems installed under the MOA's jurisdiction are supervised by a registered engineer or their staff (whether it's one of our certified installers or a homeowner). Is something more stringent needed in this case? Do they need to be a certified installer with the ADEC? Or if the homeowner desires to install the system, do they need to get approval from ADEC?

This letter issues a Conditional Separation Distance Waiver for the requested reduction of the State's minimum separation distance requirement between drinking water wells and sanitary sewer components, as detailed in the submitted engineering information and outlined below. Project Description This property is located on Shorecrest Drive and backs up to the bluff along Turnagain Arm. Many lots in this area are served by the Sand Lake Services Public Water System, PWSID 210485, or other drinking water wells, and they have individual sewer systems,typically onsite septic tanks and drainfields. Two of Sand Lake PWS's groundwater wells are nearby (Wells #1 and #3). The majority of Lot 22 is within the 200 foot protection radius around both wells. The only portion outside of 200ft is the steep bluff dropoff to the coastline. Well #1— Drilled May 9, 1964 to a total depth of about 212 feet. Cased to 206 feet. Well #3 — Completed February 11, 1995. The well log (WELTS #23107) shows it was grouted, and that it was cased to 525 feet with the intake screen starting at 513 feet. This property proposes to install a septic tank and trench drainfield, and is requesting to place them within the 200ft separation distance, but no closer than 120 feet to the Sand Lake PWS wells. The wastewater system must be installed by a person that meets the requirements of 18 AAC 72.015 and component details include: - Septic tank: 1,500 gallon, dual compartment, polyethylene, single piece construction - Drainfield: deep trench, 500 fe minimum, maximum depth 12 feet o Space for a backup drainfield is available towards the bluff which would require installation of a pump/liftstation and waiver of bluff setback requirements Page 1 of 3 Seacliff S/D, Block 1, Lot 22A 3/23/2021 Limitations This determination was based on current site conditions and well information available to the Department. Occurrences of floods, earthquakes, and human activity can change the geophysical, chemical, and biological conditions under which this determination was made. This determination does not preclude the Department from reevaluating this separation distance waiver in the event such conditions change or additional information becomes available to the Department that would warrant further review. Approval of this waiver does not obligate the department to approve future waiver requests proposing the same design, is not an approval of omissions or oversights, and does not guarantee correctness of the functional design or waive the owner's responsibility for continued compliance with state, federal, and local regulations. APPeal Process The applicant, owner or operator, or other person adversely affected by this decision may request an informal review of this decision in accordance with 18 AAC 15.185, or may request an adjudicatory hearing in accordance with 18 AAC 15.195-15.340. Requests may be sent by mail, email, or facsimile. Informal review requests must be received by the Division Director within 20 days of this decision. Adjudicatory hearing requests must be received by the Commissioner within 30 days of this decision or the decision of the informal review issued by the Division Director; otherwise, the right to appeal is waived.

Box 196650 Anchorage, AK 99519-6650 Ref: Proposed Septic System for Lot 22A, Block 1; Seacliff Subdivision ADVANTEX"' TREATMENT SYSTEM To whom it may concern: 1. GENERAL: The proposed 4 bedroom home will be served by a public water system and a private septic system. A test hole was excavated on the property. We are proposing to design the septic system around the 30 foot radius of this lest hole. Due to the cutbank to the south, we are proposing to use an Advantex treatment system and a deep trench type drainfield. 2. SOILS: See the attached log, which shows the soil classifications, groundwater monitoring, and the percolation test results. 3. DRAINFIELD APPLICATION RATE: The intent is to install an Advantex Treatment System that will allow the use of a small drainfield in the area around the 30 foot radii of the test holes. The Advantex system has received class III approval and we are going to conservatively assume an application rate of 3.0 GPD/FT2. 4. TRENCH DESIGN: a. Percolation Rate: <1 minutes/inch b. Allowable Application Rate for Class III System: 6.0 gallons/day/fl c. Proposed Application Rate: 3.0 gallons/day/R2 d. Number of Bedrooms: 4 e. Design Flow: 600 gallons per day f. Minimum Absorption Area: 200 n2 g. Total Depth: 12 feet (max.) h. Effective Depth: 7.0 feet i. Width: 2.5 feet j. Minimum Length: 15 feet long k. Effective absorption area: 210 flZ 3701 E. Tudor Road, Suite 101 • Anchorage, AK 99507 Ph: (907)337-6179 • Fax: (907)338-3246 • Website: www.akwwc.com 5.ORENCO PACKAGE SYSTEM: The STEP tank with the Advantex Treatment System will be manufactured by Anchorage Tank & Welding to meet the latest design criteria established by Orenco Systems, Inc. The point of contact at Anchorage Tank is Lowell McNutt. As with their standard STEP tank, it is equipped with a high water alarm per M.O.A requirements. 6. SURFACE WATER: There is no surface water within 100 feet of the proposed septic system upgrade. 7. TOPOGRAPHY: As can be seen on the attached design drawing the average topography in the area of the proposed drainfield is relatively flat. There is a steep bluff approximately 45 feet south/southwest of the test hole. We request that a 35 feet separation distance waiver from the top of this slope to the proposed drainfield be granted. Given the porosity of the soils there will be a great amount of lateral movement and minimal horizontal movement. In short, there is minimal risk with the granting of this waiver. 8. WAIVER TO CLASS "A" WELL: There is a class "A" well to the north east of the property. We a have recently obtained a 140 foot waiver to the class "A" well to the proposed septic system. 9. DISINFECTION SYSTEM: Due to the proximity of this system to the above well, we are required to install a disinfection system per the A.D.E.C. waiver. We are proposing to install a Sanuri) disinfeciton unit and a chlorine contact manhole in the line to the drainfield. 10. CLOSING: I am open to any suggestions from your department that would be an improvement to the proposed system. I am unaware of any negative impacts that this installation would impose on adjacent wells, or septic systems. If you have any questions, please call us at M.S. NOTE: Attached is a site plan drawing, a design drawing, an Advantex detail, a trench detail, a soil log, and a 7 page construction specification letter which are all part of the design package for this septic system. 3701 E.

Tudor Road, Suite 101 Anchorage, Alaska 99507 Re: Seacliff S/D, Block 1, Lot 22A- Request for a Separation Distance Waiver Between a Class A Public Water Source and a Proposed Soil Absorption System, PWSED # 210485, ADEC Project # 3624, Dear Mr. Gamess: The Department has reviewed your request for a waiver received on October 16, 2003 between the existing class A public water system and a proposed Advantex wastewater treatment system that discharges to an on -lot soil absorption system that serves a 4 bedroom single family house. According to your submittal the soil conditions are rated as sand. The home is designed with a 1500 gallon advance system with a design flow of 600 gallons per day. The absorption field is sized at 210 square feet, based upon a design application rate of 3 gallons per square foot per day. The separation distance requested from the class A source well to the replacement field, and the proposed drain field is 140 feet. The advantex unit is to be located at a scaled distance of 150 feet from the source well. The lot also has a cliff that is located 35 feet from the proposed drain field which will also need to be waived to allow the development to proceed. Waivers Your requests for waivers between the Class A public water source and the proposed on -lot wastewater system along with a review of the well logs, soil reports, current water sample results, and the plan drawings has taken place. Based on the information submitted, it appears the waiver requests are protective of public health, therefore, in accordance with the State Drinking Water Regulations (18 AAC 80.020), the following waivers are granted with two conditions that will follow after the waiver descriptions. The separation distance between the Class A public water well located near Endicott Street and Shorecrest Drive and both the proposed soil absorption system and the replacement soil absorption system serving the home on lot 22A, Block 1, Seacliff Subdivision are waived from 200 feet to 140 feet. The separation distance between the Class A public water well located as stated above and the Advantex treatment on Lot 22A, Block 1, Seacliff Subdivision has been waived from 200 feet to 150 feet. The separation distance between the top of the cutbank and the proposed on -lot soil adsorption system has been waived from 50 feet to 35 feet. Conditions placed on the waivers are as follows: 1. that the waste stre�benfected2. that annual inspecs ted to this office. The distances noted in the waivers are from your submittal. It appears that these distances are from the nearest edge of the wastewater disposal system component to the nearest edge of the existing Class A public water system well or the top of the cutbank. If any wastewater disposal system fails or contamination can be traced back to the system, the waivers will be invalid. This approval does not imply the granting of additional authorizations nor obligate any state, federal or local regulatory body to grant required authorizations. Any person who disagrees with this decision may request an adjudicatory hearing in accordance with 18 AAC 15.195- 18 AAC 15.340 or an informal review by the Division Director in accordance with 18 AAC 15.185. Informal review requests must be delivered to the Division Director, 555 Cordova St., Anchorage, Alaska 99501, within 15 days of the permit decision. Adjudicatory hearings requests must be delivered to the Commissioner of the Department of Environmental Conservation, 410 Wiloughby Avenue, Suite 303, Juneau, Alaska 99801, within 30 days of the permit decision. if a hearing is not requested within 30 days, the right to appeal is waived.

Septic System Upgrade at Seacliff S/D, 22A, Block 1 Dear Mr. Rieth, In order to comply with your October 31, 2003 letter, which granted waivers that were necessary to install the subject septic system, we are proposing to install a chlorine disinfection system. The proposed system will be a Sanuril, tablet type, chlorinator in a manhole between the Advantex system and the pump vault, followed by a chlorine contact tank. As the effluent from the Advantex system flows to the pump vault, it will pass through the Sanuril unit where it will come into contact with the chlorine tablets. The chlorinated effluent will then flow through a contact tank (buried fiberglass basin with access manhole). The contact tank piping will be plumbed in the bottom and out the top so as to maximize the contact time. Effluent from the contact tank will then flow into the pump vault, where it will be transferred to the drainfield for final disposal. We are requesting your concurrence regarding the proposed disinfection system. If you have any questions, or require additional information, please contact me at 337-6179.
