Conditional Certificate of Onsite Approval Request
Septic System Permit Request
Ladies and Gentlemen:
I am writing to request a permit to construct a new septic system be issued for this property and a
conditional Certificate of Onsite Approval (COSA) be issued. The proposed systems will serve an existing
four-bedroom house. Currently the lot is developed. The lot is served by a community water supply. The
existing septic system shall be reused. A diverter valve will be installed between the existing tank and the
existing field. The surrounding developed lots are served by private water systems and community water
system. The private wells are located over 100 feet from the proposed soil absorption system. The
community well is located over 200 feet from the proposed upgrade.
1. Conditional COSA. The Owner is in the process of selling this property. The existing system was
located and inspected. The system was test for operation and was found that it could not accept the required
150 gallons per bedroom per day (600 gpd). The system is able to absorb approximately 250 gallons per day.
There will be no health risk in approving this Conditional COSA as we will be installing the new system in
June.
2. Soils. A single test hole was excavated. See the attached soil log. Ground water was monitored for
seven days. No ground water was monitored to a depth of 18 feet below ground level after the monitoring
period. Bedrock was not encountered in the test hole. It is my opinion, based on the results of the percolation
tests and overall soils appearance; an application rate of 1.2 gallons/day/square feet should be used, using a
conventional treatment system.

Page 2 of 2
4. Surface Yater: There is no surface water within 100 feet of the proposed septic tank and the
existing drain field. The proposed drain field upgrade will maintain at least 100 feet from all surface water
and drainage ditches.
5. Topography: The average topography in the area of the proposed septic system is approximately 2
percent based on the survey information. The proposed upgrade is located in a saddle on the lot. The
proposed installation will be greater than 50 feet from the shoulder of the steep slopes.
6. Drawing Markings: The Drawings are marked "For MoA Review Only". When written notification
that the review is complete and that there are no further comments is received from MoA On -Site
Department, the note will be removed and "Released for Construction" drawings will be issued.
The proposed installation will not affect the future development of the surrounding or existing lots. There
are no wells or septic systems within 100 feet of the proposed septic location.
If you have any questions or concerns, please contact me at 272-8218.
Sincerely,
Steven R. Pannone, P.E.
Owner/Civil Engineer

Engineers Comments: In conducting an adequacy test, l attempt to provide a thorough, conscientious engineering analysis of the system in
accordance with htOA DSD Guidelines & Regulations. The reported results describe the performance of the system under the conditions
encounicre i. the time et the lest, and separation distances measured to readily identifiable tcatures.
The operational life of all wells and septic systems depend on the local soil condition, ground water
levels that may fluctuate during the year, and the water usage of the family being served by the system.
These conditions arc outside the control of the evaluator of this system. All systems eventually fail and
satisfactory test results do not guarantee future performance of the system, nor do they guarantee that
there are no hidden defects or encroachments. PES can therefore not provide any warranty for future
performance nor give any estimate of how long the system will continue to meet the operational
requirements of the MOA DSD. The content of this report is for the sole benefit of the owner listed
above. Any reliance upon or use of this report by any other person or party is not authorized nor will it
confer any legal right whatsoever.

Engineers Comments: In conducting an adequacy test, I attempt to provide a thorough, conscientious engineering analysis of the system in
accordance with MOA DSD Guidelines & Regulations. The reported results describe the performance of the system under the conditions
encountered at the time of the test, and separation distances measured to readily identifiable features.
lie operational lire of all wells and septic systems depend on the local soil condition, ground water
levels that may fluctuate during the year, and the water usage of the family being served by the system.
Thcse conditions are outside the control of the evaluator of this system. All systems eventually fail an
satisfactory test results do not guarantee future performance of the system, nor do they guarantee that
there arc no hidden detects or encroachments. PPS can therefore not provide any warranty for future
performance nor give any estimate of how long the system will continue to meet the operational
requirements of the MOA DSD. The content of this report is for the sole benefit of the owner listed
above. Any reliance upon or use of this report by any other person or party is not authorized nor will P
confer any legal right whatsoever.

Conditional Certificate of Onsite Approval Request
Septic System Permit Request
Ladies and Gentlemen:
P.O. Box 102954
ge, Alaska, 99510
I am writing to request a permit to construct a new septic system be issued for this property and a
conditional Certificate of Onsite Approval (COSA) be issued. The proposed systems will serve an existing
four-bedroom house. Currently the lot is developed. The lot is served by a community water supply. The
existing septic system shall be reused. A diverter valve will be installed between the existing tank and the
existing field. The surrounding developed lots are served by private water systems and community water
system. The private wells are located over 100 feet from the proposed soil absorption system. The
community well is located over 200 feet from the proposed upgrade.
1. Conditional COSA. The Owner is in the process of selling this property. The existing system was
located and inspected. The system was test for operation and was found that it could not accept the required
150 gallons per bedroom per day (600 gpd). The system is able to absorb approximately 300 gallons per day.
There will be no health risk in approving this Conditional COSA as we will be installing the new system in
June. f-sTr6iTS, =-r tco1(LA-P A Nvj-t-rtl Fttbz.zT�.
2. Soils. A single test hole was excavated. See the attached soil log. Ground water was monitored for
seven days. No ground water was monitored to a depth of 18 feet below ground level after the monitoring
period. Bedrock was not encountered in the test hole. It is my opinion, based on the results of the percolation
tests and overall soils appearance; an application rate of 1.2 gallons/day/square feet should be used, using a
conventional treatment system.

4. Surface Nater: There is no surface water within 100 feet of the proposed septic tank and the
existing drain field. The proposed drain field upgrade will maintain at least 100 feet from all surface water
and drainage ditches.
5. Topography: The average topography in the area of the proposed septic system is approximately 2
percent based on the survey information. The proposed upgrade is located in a saddle on the lot. The
proposed installation will be greater than 50 feet from the shoulder of the steep slopes.
6. Drawing Markings: The Drawings are marked "For MoA Review Only". When written notification
that the review is complete and that there are no further comments is received from MoA On -Site
Department, the note will be removed and "Released for Construction' drawings will be issued.
The proposed installation will not affect the future development of the surrounding or existing lots. There
are no wells or septic systems within 100 feet of the proposed septic location.
If you have any questions or concerns, please contact me at 272-8218.
Sincerely,
Steven R. Pannone, P.E.
Owner/Civil Engineer
