P. O. Box 196650 Anchorage, Alaska 99519 Subject: Snow Crest View, Lot 16 Septic System Permit Request Ladies and Gentlemen: I am writing to request a permit to install an upgrade septic system be issued for this property. The proposed systems will serve an existing three bedroom (3) bedroom house. Currently the lot is developed. The existing drain field and tank are in failure and will be decommissioned per code. A new upgrade 1000g septictank and drain field will be installed. The surrounding lots to the north, south, and west are developed and served by private septics with a community class 'A' well PWSID# 2210891 that is located 150' from the proposed tank and 170' from the proposed drain field. PES has applied for a separation distance waiver from the ADEC for this system to the class'A' well.. The lots to the east are served by private wells and septics. The private wells are located over 100' from this system. Soils. One test holes were performed by Pannone Engineering Services in September of 2014, and groundwater was monitored for seven days. Ground water was not observed after the seven day monitoring period. It is my opinion, based on the results of the percolation tests and overall soils appearance; an application rate of 0.8 gallons/day/square feet should be used for a conventional wastewater system. Soil Absorption System Design. a. See Sheet 2 of the design package. 2. Surface Water: There is no surface water within 100 feet of the proposed septic tank and drain field. The proposed drain field upgrade will maintain at least 100 feet from all surface water and drainage ditches. 3. Topography: The existing topography slopes from the south to the north at approximately 3%. There are no steep slopes in the vicinity of the drain field. Mailing: P.O.

Department of Environmental Conservation DIVISION OF ENVIRONMEN FAL HI~ALT}t Drinking Water Program 700 E Bogotd ~d, g[dg B S~e 103 November 5, 2014 Steven Pannone, P.E. P.O. Box 100217 Anchorage, AK 99510 RE: Snowcrest View South Separation Distance Waiver PWSID #: 2210891; Community Water System; Source: Ground Water Dear Mr. Pannone: On October 23, 2014 this office received a separation distance waiver request for the Snow Crest View South community water sys tern. 712qe on-site wastewater disposal system serving the home located on Lot 16 Snow (;rest Viexv South subdivisinn bas recently failed and a new system has been designed to replace it. The waiver request is for the following lesser separation distances: 150 feet between the septic tank and the community water source (50 feet less than the required separation distance of 200 feet); and 170 feet betxveen the drainfield and community water source (30 feet less than the required ~ninimum separation distance of 200 feet). In your enginee£mg report you provided the following justifications for the lesser separation distances: I. The well has a total depth of 74 feet, and is cased the entire depth. The static water level is approx/mately 30 feet below the ground surface; 2. Groundwater in the area typically flows from the southwest to the northeast which would direct potential contamination at the site away from the welt; 3. The new wastewater disposal system serving Lot 16 will be located further away from the xvell than the system it is replacing; and 4. Because the water system is a community water system, it is tested regularly for contaminants. ~llqe sampling records for this water system show that k has been consistently free of total coliform bacteria and as of October 25, 2013 the nitrate/nitrite levels are undetectable. Although the separation distance between the well and the wastewater system components is less than the distance prescribed by regulation, based on specific site conditions and the mitigating factors listed above, the potential for contamination due to the lesser separation distance appears to be low. Therefore, a waiver for the lesser separation distance described above is approved in accordance with the provisions of the State's Drinking Water Regulations. Approval Limitations Tbis waiver is valid only for the proposed use and the system described in the waiver request on file hq this office, This approval does not imply the granting of additional authorizations, nor obligate any federal, state or local regulatory body m grant required authorizations. 21tis is not an approval of onfissions or oversights by this office Steven Pannone, P.E. 2 November 5, 2014 or noncompliance with any applicable regulation. The Dep~tment's ~vaiver approval does m,t guarantee correcmess of the functional design or waive the ow'net's responsibility for continued compliance xvith State regulations. Appeal Process Any person who disagrees with fi'ds decision may request an adjudicatory hearing in accordance with I8 AAC 15.I95 ~ 18 AAC 15.340 or an informal review by the D/vision Director in accordance with 18 AA(; 15.185. Requests for an adjudicatory hearing or informal review may be made by mail, electronic mail, or facsimile.
