Alaska Water R Wastewater Consultants, Inc. 6901 Debarr Road, Suite 2-B Anchorage, Alaska 99504 Re: Lot 5, Block 2, Lakeridge Terrace Subdivision, Non -Objection to Proposed Wastewater Disposal Systems, ADEC Project # 1711 Dear Mr. Garness: This is in response to the record drawings, Documents of Construction, and related information received in this office on January 31, 2003. 1 have reviewed the record drawings, file records, and the related information associated with a duplex with five bedrooms. I called your office and found that the Municipality had completed the test operation of the AdvanTex system before this unit had been completed. It appear that the AdvanTex wastewater disposal system with an on -lot absorption system has been constructed in accordance with the approved construction plans. Therefore, in accordance with State Wastewater Disposal Regulations (18 AAC 72.240), final operational approval for the system is granted. The signed final operational approval portion of the Construction and Operation Certificate, constituting final operational approval, is enclosed. 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. Thank you for your cooperation. If you have any question please do not hesitate to contact me at 269-7519.

After reviewing the submittal and discussing the proposed wastewater treatment and disposal system with you and other departmental staff, it is clear that a complete engineering plan review will need to be completed. I have completed my review of the submitted information and the information that I was able to obtain from the Municipality of Anchorage regarding the test results on effluent from already installed Advantex wastewater treatment and disposal systems already installed in Anchorage. Based on this review, I have the following comments. Although the wastewater stream will be generated by a duplex, the proposed treatment system [2000 gallon S.T.E.P. septic tank, three AX -10 filters, and a soil absorption system with 190 square feet of effective absorption area] requires written approval from the Department before installation can start. From the submitted information, it appears that the proposed treatment and disposal system was designed to meet the minimum requirements of the State Wastewater Disposal Regulations and guidance. Therefore, in accordance with State Wastewater Disposal Regulations [18 AAC 721, construction approval is granted. A Construction and Operation Certificate, with the construction section signed, constitutes construction approval for this project. Before final operation approval can be issued the following items will need to be provided to this office for review and approval: The installation of the proposed wastewater treatment and disposal system will need to be completed under the supervision of a Professional Engineer. Jeffrey A. Garness Page 2 12/05/01 2. Record drawings will need to be submitted to this office under the;stamp of a Professional Engineer. The record drawings will need to verify the separation distance between the lowest point of the soil absorption system and seasonally high ground water level. In addition, verification that the minimum separation distance to any impermeable layer is also being met and in-situ soil conditions will also need to be submitted with the record drawings. 3. Verification that the existing soils/fill material can hydrualicaly handle the proposed application rate of 4.0 gallons per day per square foot. 4. Copies of sieve analysis showing that the sand being used in the sand filter layer meets the specifications. 5. The attached forms will need to be filled out and included with the record drawings. 6. Engineering design calculations showing that the proposed system will be able to handle the proposed flows. The above issued approval does not imply the granting of any additional authorizations, nor obligate any local, state, or federal regulatory body to grant required authorizations. If it is possible, once the proposed wastewater treatment and disposal system is installed that the system can be included in the current sampling program being completed for the Municipality of Anchorage, the results would be help for the Department. Thank you for your cooperation and coordination with this Department. If you have any questions, please do not hesitate to contact me. Sincerely, Keven K Kleweno, P.E.

March 28, 2000 State of Alaska Department of Environmental Conservation Division of Environmental Health Drinking Water & Wastewater Program 555 Cordova Street Anchorage, Alaska 99501 Attn: Kevin Kleweno, P.E. Subject: Lakeridge Terrace, Lot 5, Bk 2. Located at the north end of Fire Lake. Dear Mr. Kleweno: The subject lot is undeveloped and located on the waterfront of Fire Lake. In the past the Municipality of Anchorage has not been receptive to allowing the installation of a septic system because of the fact that there is not 2 feet of accepting soils over the shallow bedrock, which underlies much of the property. The current owner, Rich Young is proposing to build a duplex on the subject property during the summer of 2001. In order to do this, a septic system site will have to be located on the property. It is our understanding the neither ADEC or the MOA are reviewing or issuing permits for septic systems that are served by duplexes. In short, there currently is no review process. Regardless, because of the unique circumstances regarding the property we requesting your involvement. We are proposing to excavate the organic layer away from the proposed septic system site and import clean fill material so as to create an artificial 4 foot accepting stratum. It is our understanding that there is nothing in the State wastewater regulations which prohibit installing a drainfield on imported fill material. The classified fill will be watered and moderately compacted in 12-18 inch lifts as it is placed. Documentation of the organics removal and importation of the fill material will be done under the direction of a professional engineer. After the soil has settled a percolation test will be run to determine the drainfield application rate. 6901 Debarr Road, Suite 2-B *Anchorage, Alaska 99504 Ph: (907) 337-6179 *Fax: (907) 338-3246 *email: awws@alaska.net Page Two It is the intent to install a Reactex type septic system that will produce a effluent that exceeds secondary treatment standards, and has low nitrate concentrations. Our monitoring data on these systems indicates that they consistently produce a high quality effluent. The Reactex effluent will be discharged to a small bed type drainfield that is expected to be about 13 feet by 13 feet (150+ square feet). We will be able to install this system without encroaching upon any surface waters or adjacent/proposed wells. It is our goal to place the fill in the spring/summer of 2000 and begin construction one year later. It is my opinion that this installation can be done without adversely impacting the environment or public health. In fact, it will probably be one of the most environmental friendly systems located on Fire Lake. Thank you for your assistance and consideration in this matter.

Box 196650 0 0 Anchorage, AK 99519-6650 RE: Lakeridge Terrace Lot 5, Block 2 35- /X'� Dear Mr. Roth, We propose to prepare a site for an alternative septic system on the subject lot located on Lower Fire Lake. As you may recall, the site evaluation on October 20, 1999 with Mr. Jim Cross of your office, you, and myself indicated only 2 feet of native soils above the bedrock. We propose to excavate the native soils, bring in a fill material to create a mound soil absorption system, and ultimately install a Reactex wastewater treatment system The "construction of an artificial accepting stratum" is addressed in the Revised Wastewater Disposal Regulations, dated October 12, 1990 under Section .060.I. Following removal of the native soils, we propose to bring in fill material to a depth of 3 or 4 feet. The material will be compacted and allowed to settle for 12 to 24 months. We request guidance from your office on what type of fill material should be used. Prior to construction, a sieve analysis will be performed on the fill material, to ensure that it meets your requirements. All field permits, and a design plan will follow your advice on the type of fill material to be used. Thank you for your assistance in this request.

The permit for an on-site wastewater disposal system was denied due to the lack of a sufficient layer of accepting soil. Anchorage Municipal Code section 15.65 requires a minimum of two feet of unsaturated accepting soil for the installation of a disposal system. Multiple test holes showed less than one foot of accepting soil is available on your property. The installation of a holding tank on this property is not an option, for Anchorage Municipal Code does not allow for the use of a holding tank in the development of a property. Holding tanks may be used only when an existing permitted wastewater disposal system fails, and an engineer certifies that the property will not support a replacement system. If you have any further questions, please call me at 343-4744. SinceFely, James Cross, PE Program Manager On -Site Water Quality P-549 LAKE RIDGE TERRACE SUBD.
