Advanced Treatment System
Per the request of the contractor, he would like to switch to a CAT II Quanics Aerocell
system instead of an Orenco CAT III Advantex system. In short, we would be switching
from CAT III to CAT II and would need a total FT of 150 FT (instead of 125 FT 2) for an
application rating of 4 (<1 min/inch soil) for a 4 -bedroom home (600 FTz). We are
proposing to increase the width of the existing bed by 1 foot. In summary, the proposed
bed will be 6 feet wide instead of 5 feet wide. The contractor is proposing to use an
Anchorage Tank 1500 -gallon steel STEP tank with a polyurethane coating. Please let
me know if you have any questions or need additional information/design drawings.
We are unaware of any adverse impacts this installation or waivers would have on
adjacent wells or septic systems. If you have any questions, please contact us at 337-

PID#: 090-042-29
Legal Description: Chugach Park View Lot 29
Engineer: Garness Engineering Group
Applicant: Tyler Weaver
Your request for a waiver of the required 50 feet horizontal separation from the Category III
advanced wastewater system septic tank and absorption field to surface water has been approved.
The approved separation distance is 35.0 feet. See engineer's waiver request for justifications for
granting this waiver and see engineer's site plan for reference to which surface water features this
request applies to and additional mitigating factors (i.e. berm).
This waiver approval applies to the proposed septic tank and absorption field only. Any future
upgrade to the on-site wastewater disposal system will require all separation distances be met or
another approval from this department.

Ref: Septic system design for Chugach Park View; Lot 29
To whom it may concern:
The existing lot is vacant. Per the request of the homeowner, he would like a 4-bedroom
septic design with his home located between the two creeks (see attached 100 scale).
As can be seen on the attached MOA wetlands map and the 100 Scale, there are "class
A" wetlands on the property, as well as two creeks (surveyed in by Fred Walatka, PLS),
limiting the location of the septic system. Due to these facts and the presence of high
groundwater (see attached soil log), we are proposing CAT III Advanced treatment
(Advantex). We are proposing to install a new 1500-gallon Advantex tank with Advantex
components, one AX-20 Pod and a mounded five-wide type trench with a 4.5-foot MOA
approved sand filter. Additionally, due to high groundwater, we are proposing to utilize
Engineered Receiving Soil. We are proposing to excavate down to 3.5 feet (into the GP-
GM material), import 4.5 feet of MOA approved sand, and construct the drainfield above
grade. It should also be noted that MOA onsite employee Tim Ecklund and GEG
employee David Garness met onsite on 6/13/2018 to discuss the proposed design. Tim
Ecklund was in agreement with the proposed location and felt as though it would not
pose a health/safety risk to install the trench as proposed. Comments regarding the
design are summarized as follows:
1. SOILS: When excavating the percolation bench/testhole the ground was frozen to
about 2.5+ feet and groundwater was at approximatley 3 feet. Due to the high
groundwater, and frozen soil, a percolation test could not be performed (see attached
soil log). However, a soil sample was pulled from the GP-GM material below the ML
layer and submitted to Alaska Test Labs for sieve analysis (attached). As can be seen
on the attached sieve analysis, the soil is classified as a GP-GM. It should be noted that
during the excavation of the testhole, water was pouring into the testhole at a depth of
approximately 3.5 feet, indicating a percolation rate of less than 1 minute/inch. Based
upon this fact, we are proposing an application rating of 5 GPD/FT2 for a CAT III
system. This application rating is used for percolation rates of up to 15 min/inch, which
is conservative and reasonable for the application of this design.

2. DRAINFIELD DESIGN: See attached design drawing for drainfield specifications.
3. SURFACE WATERS: As can be seen on the attached design drawings, there are
creeks to the west and east. See the "Waiver" section below and the design drawings
for more information.
4. TOPOGRAPHY: As can be seen on the attached design drawing, the topography
around the proposed drainfield is less than 10%.
5. WAIVER: We are requesting several waivers for the subject property. Below is a list
of the waiver request, followed by its justification:
• Drainfield, Tank, and AX-20 pod to surface water from 50 feet to 35 feet
• The use of Engineered Receiving Soil
• Waive the requirement for a percolation test
Justification for granting these waivers is as follows:
• Due to the abundance of surface water on the property and the presence of
Class A wetlands, there is minimal room to place an onsite septic system. We
feel as though the proposed location maximizes the separation distances given
the proposed home location.
• We are proposing the use of CAT III advanced treatment. The effluent quality will
be much greater than that of conventional treatment.
• We are proposing to use a 4.5 foot sand filter, after passing through the sand
filter, the effluent quality will be even greater than that of CAT III after passing
through the sand filter.
• The Advantex system will be remotely monitored. If the system were to go into
"high-level" alarm, the service provider would be notified, and corrective action
taken.
• The area between the proposed drainfield and surface water is vegetated.
• During the excavation of the testhole, the west creek did not appear to be
flowing.
We are unaware of any adverse impacts this installation or waivers would have on
adjacent wells or septic systems. If you have any questions, please contact us at 337-
6179. Thank you or your assistance.

Article 5.4 Sizing the Absorption Field
After selecting the most appropriate type of absorption system for a given site,the infiltrative
surface is sized based on soil conditions. Recognizing soil conditions and accurately rating the
absorption capacity of the soils is vital to the design of a good system. At least two prospective areas
should be investigated.
When conditions are suitable, a deep trench soil absorption system is recommended and should be
used because they tend to out-perform other system types.
The perimeter of each proposed absorption area should be temporarily marked using stakes and
string line. Every effort should be made to keep heavy equipment and vehicular traffic outside of the
marked areas to prevent compaction effects on the soil absorption characteristics.
The following sizing information shows the specific data needed to find the recommended soil
loading or application rate,in square feet of infiltrative area per bedroom.
• GW (Well Graded Gravel with percolation rate faster than 1): A two (2) foot thick sand liner
beneath the sewer rock is required. Use an application rate of 150 square feet per bedroom.
• GW (Well Graded Gravel with percolation rate of 1 or slower):A sand liner beneath the sewer
rock is not required. Use an application rate of 125 square feet per bedroom.
• GP (Poorly Graded Gravel with percolation rate faster than 1): A two (2) foot thick sand liner
beneath the sewer rock is required. Use an application rate of 150 square feet per bedroom.
• GP (Poorly Graded Gravel with percolation rate of 1 or slower):A sand liner beneath the sewer
rock is not required. Use an application rate of 125 square feet per bedroom.
• SW (Well Graded Sand): Use an application rate of 150 square feet per bedroom.
• SP (Poorly Graded Sand): Use an application rate of 150 square feet per bedroom.
• GM (Silty Gravel),SM (Silty Sand),or ML(silt): Requires an engineer's soil log and percolation
test. Sizing requirements are as follows:
Percolation Rate (min/in) Application Rate for GM.SM or ML
• Between 1 & 5 use an application rate of 125 square feet per bedroom
• Between 6 & 15 use an application rate of 190 square feet per bedroom
• Between 16&30 use an application rate of 250 square feet per bedroom
• Between 31 & 60 use an application rate of 335 square feet per bedroom
• Between 61 & 120 requires engineering plans and prior ADEC plan approval
Above 120 is considered to be impermeable and is not suitable
• CL or CH (clay),OL(organic silt or clay),PT(peat): Requires engineering plans and prior ADEC
plan approval.
