Garness Engineering Group 3701 East Tudor Road, Suite 101 Anchorage, Alaska 99507 Sean Parnell, GOVERNOR 555 CORDOVA ANCHORAGE, AK 99501 Phone: (907) 269-7519 Fax: (907) 269-3487 http://www.state.ak.us/dec/ Re: Coronado Subdivision, Lot 4, Block 2 -Eagle River -Final Operational Approval for a Wastewater Collection System-ADEC Plan Tracking Number 8443 Dear Mr. Garness: On July 26, 2011 the Department received the document and record drawings for an onlot domestic wastewater treatment system with a new 2,000 gallon, two compartment septic tank and a new soil absorption system (Deep Trench with an effective depth of 7 feet) for the 6 bedroom Duplex at the above location. The new 2,000 gallon septic tank was installed and now allows the effluent to enter the midpoint of the 65 foot long deep trench system. You submitted a field sample of the deeper sands from the site. This sand was not required to be replaced because the existing homes are connected to public water from the city and this sand material will provide the adequate treatment of the effluent from the septic tank. The soil absorption system was designed providing 65'x (2x7') = 910 ft2 which was within engineering standards for this type of design. The Department has reviewed the documentation and the record drawings submitted for the onsite wastewater disposal and treatment system and per the Wastewater Regulations 18 AAC 72.240, Final Operational Approval for the proposed system is hereby issued. A "Certificate to Construct" for the duplex wastewater system is enclosed. Please use the referenced plan number in correspondence regarding this system. 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 Street, Anchorage, Alaska 99501, within 15 days of receiving the decision. Guidance information on the informal review process may be found at http://www.dec.state.ak.usZcommish/ReviewGuidance.htm. Adjudicatory hearings requests must be delivered to the Commissioner of the Department of Environmental Conservation, 410 Willoughby Avenue, Suite 303, P.O. Box 111800, Juneau, Alaska 99801, within 30 days of the decision. If a hearing is not requested within 30 days, the right to appeal is waived. Thank you for your cooperation.
