Permit Application Comment Response & Waiver Request
Dear Mr. Roth,
VEI Consultants Received comments from your office for the subject permit dated July
20, 2009. We have addressed the remarks and are submitting the additional information
and response to each comment as follows:
1. A sand filter will not be used on the system. Material specifications for filter
material have been removed from the design specifications.
2. A roadside ditch with side slopes greater than 25% exists within 50ft of the
proposed disposal field. We request you grant a 31.5' separation distance waiver
from the top of slope of the ditch to the disposal field. Information pertaining to
this request and justification for the waiver are as follows:
a. The primary disposal field is located in a relatively flat area at the toe of an
existing hill on the lot. Topography dictates this is the best location for the
disposal field minimizing the construction effort of placing the absorption
trenches on the side slope of the hill. The current location also minimizes
tree removal during construction.
b. A cross-section of the disposal filed and roadside ditch was developed per
the requirements of the MOA Building Safety Division Memorandum
"Slope Setbacks from >25%" dated April 7, 2004. As shown in Figure 4, a
grade line of 25% originating at 2.5R above the distribution piping and
drawn perpendicular to the distribution pipe does not daylight within 3511
On -Site Sewer Permit Application for Lot Greatland Fstates # 1. Block 2. Lot 6; T/3N R111' 510.: Grid N117260
Page 1 of 2
horizontally from the absorption trench, thus satisfying the conditions of
the memorandum.
c. As shown in the attached soils logs, no groundwater or impermeable layers
were encountered within the vicinity of the disposal field. Additionally,
the roadside ditch is shallow, averaging 2-3ft in depth, and sees only
seasonal runoff during times of peak snow melt; therefore we anticipate no
adverse effects in locating the disposal filed within 50ft of the ditch side
slope.
3. The drawing scale on Figure 2 has been corrected (see attached)
4. A reserve field has been designed. VEI conducted field investigations including
digging a test pit and performing a percolation test for the reserve field location.
The Soils Log—Percolation Test for Test Hole #4 located in the vicinity of the
proposed disposal field is attached. No groundwater was observed in these test
holes/monitoring pipes. Immediate neighboring septic systems are all more
than100' away, and no private wells within 100' or community wells within 200'
of the reserve site. Existing grade was verified in the field and no slope greater
than 25% is within 50ft down gradient from the reserve field location.
Groundwater monitoring is ongoing; however, we do not anticipate groundwater in
the monitoring tube. The percolation rate for the reserve field is 13minutes/inch
which will require a smaller absorption trench system than the primary location.
Per the Wide Drainfield Design Specifications, the reserve system will require two
4711 trenches at 511 wide and with 48inches of gravel below the distribution pipe.
5. Specifications have been revised to include decommissioning of the existing crib.
6. Absorption field design has been revised to allow connection of the gravity line at
the midpoint of the absorption trenches. (see attached)
7. Soils logs have been updated to include Unified Soils Classification designations.
8&9. New percolation tests were performed in accordance with Table 3-8 of the EPA
Design Manual. Percolation test results are attached.
10. The application rate on Figure 2 has been corrected (see attached)
11. An additional test hole and percolation test was performed in the vicinity of the
primary disposal field. Soils Log and Percolation Test for Test Mole #3 is
attached. As shown in Figure 2, the additional percolation test provides complete
coverage of the disposal filed within a 30' radius of Test I tole #2 and #3. The
average percolation rate is 22.7min/inch.
12. Septic Tank Installation Note 2 of the Construction Specifications directs the
contractor not to exceed burial rating of the tank. A note has been added to the
design plans Figure 3 for additional clarification.
13. The design plans have been revised to show the double cleanout as specified.
14. A cleanout has been added at the midpoint of the gravity line from the tank in
compliance with UPC code. A note on Figure 3 has been added indicating the
100ft maximum distance between cleanouts. (see attached)
I5. The intent of Absorption Trench Spec #8 is to ensure accepting soil within the
trenches meets the requirements of the design. Spec48 has been revised and
additional information has been added instructing the contractor to contact the
engineer if unsuitable material is encountered.

Page 3 of 2
We request that with this additional information the On -Site Sewer Application Permit be
approved and the distance to 25% slope waiver be granted. Based on the aforementioned
facts under comment response #2, it appears that there is minimal risk associated with
granting the 31.5ft separation distance waiver.
If you have any questions, please contact me at 337-3330.

Re: On -Site Sewer Upgrade for Greatland Estates # 1, Block 2, Lot 6
TI 5N RI W SEC10, Grid NW1260
Narrative and Permit Application
Dear Mr. Roth,
VEI Consultants was contracted to design a septic system upgrade at the above referenced
property. The homeowner wishes to upgrade their septic system, due to the age of the
existing system and desire to add two additional bedrooms to the existing three bedroom
house for total of (5) bedrooms. The proposed house, well and septic system locations are
shown on the attached Site Plan, Figure 1. We request that you approve the attached
permit application for construction of the septic system.
VEI conducted field investigations including surveying, digging test pits, performing
percolation tests and monitoring groundwater. The Soils Log—Percolation Test for Test
Holes 41 and #2 located in the vicinity of the proposed disposal field are attached. No
groundwater has been observed in these test holes/monitoring pipes. No seasonal surface
water has been observed collecting anywhere on the property. The general slope of the lot
is from southeast to northwest at a grade ranging from 5-18%.
The proposed septic design, presented in Figures 2 R 3, includes a gravity line from the
house to a 1500 Gallon septic tank, a gravity line from the tank to disposal field, and a
total 126 LF of five wide trench (divided into 2 parallel runs) with 48" of gravel beneath
the horizontal perforated pipe. The locations of all system components including clean -
outs and monitoring pipes are shown on the Septic System Plan, Figure 2.
The proposed system will not alter the existing site topography or drainage patterns
beyond the limits of the disposal field. The ground surface above the disposal field will
On -Site Sewer Permit Application for Lot Greatland &tater Hl, Block 1. Lot 6; TISN RIW S10.; Grid NW1260
Page 1 of 2
be filled up to I foot above existing to ensure that surface water does not collect above the
trenches. The area will be graded to ensure positive drainage across the disposal field.
Immediate neighboring septic systems are all more thanl40' away, and no private wells
within 100' or community wells within 200' of the proposed septic system. We do not
expect there to be any adverse effect on adjacent lots by the development of this system.
If you have any questions, please contact me at 337-3330.
Sincerely,
VF CONSULTANTS^

ON-SITE WASTEWATER DISPOSAL SYSTEM
CONSTRUCTION PRACTICES AND MATERIAL SPECIFICATIONS
LEGAL DESCRIPTION: Greatland Estates #1, Block 2, Lot 6
GENERAL:
1. The scope of this project includes the upgrade of an existing septic system by
installation of a 1500 gallon septic tank and a leach field trench to serve a 5
bedroom single family residence located on the referenced property.
2. Construction shall be in accordance with the approved site plan and design
drawings, municipal permit with any special provisions or conditions, and all
applicable Municipal Wastewater Disposal Regulations. Any deviation from the
site plan and design drawings requires engineer approval.
3. Contractor shall verify the septic tank and absorption system are a minimum 100'
away from any private wells in the area.
4. The contractor shall be responsible for obtaining any necessary underground utility
locates.
5. Any remaining test -hole excavation shall be filled and monitor tube removed.
6. Contractors installing wastewater disposal systems must be certified by the
Municipality of Anchorage On -Site Water and Wastewater Department for
systems installations. Owners installing their own systems must also receive prior
approval from the Municipal On -Site Water and Wastewater Department.
SEPTIC TANK INSTALLATION:
1. Septic Tank shall be a minimum of 1,500 gallon tank of MOA approved
construction, placed with 4 -foot minimum soil cover. The contractor will ensure
that tank installation conforms to manufacturers specifications for depth of bury,
backfill type, and compaction requirements.
2. Septic Tanks installed with less than 4 foot of cover shall be insulated. Minimum
cover with insulation shall be 2 feet.
3. The sewer piping from the existing house cleanout to the septic tank shall be 4
inches laid at a 2% minimum and insulated with 2" insulation if shallower than 3f1,
with 2fi minimum bury.
4. Construction shall include two 4 inch cleanouts for pumping access to the septic
tank. All stand pipes on the septic tank shall extend to a minimum of 12 inches
above final grade

August 3. 2009
Page 2 of 3
5. In the line between the tank and the absorption system there shall be two adjacent
cleanouts. The cleanouts shall be located on undisturbed soil not more than ten feet
from the tank. The first cleanout in the line shall be to clean the line toward the
absorption system and the second cleanout will be oriented to allow cleaning
toward the septic tank.
6. The sewer piping from the septic tank to the absorption system shall be 4 inches
laid at a 2% minimum and insulated with 2" insulation if shallower than 3ft, with
2ft minimum bury.
7. The septic tank shall be sufficiently bedded with proper material and compacting
to prevent settling or shifting of the tank.
8. The contractor shall abandon the old tank and seepage pit in compliance with the
Uniform Plumbing Code.
ABSORPTION TRENCII INSTALLATION:
1. Excavate the proposed trenches in the location and to the dimensions shown on the
design. Contractor shall ensure that 10 feet separation distance is maintained
between trenches. The bottom of the trench shall be within 2 inches of level.
2. Once the sewer rock is installed, the distribution pipe shall be installed level with
perforations faced downward. Gravel is then to be placed over the distribution
pipe to provide a minimum of 2 inches of cover over the pipe. Perforated pipe
used in gravity subsurface disposal fields shall be 4 inches in diameter.
3. A silt barrier must be installed between the final gravel layer and the native soil
backfill. Contractor shall ensure that the silt barrier covers the entire gravel
surface before placing backfill.
4. Monitor tubes shall be of 4 inch diameter, installed approximately in the locations
shown on the design, and extended a minimum of 12 inches above final grade.
The portion of the monitoring tube extending through the gravel shall be
perforated from the bottom of the trench to the invert of the distributing pipe.
5. A flow splitter (Quanics Plow Divider: GDS-ZS300, or equal) shall be placed to
ensure even flow to each trench.
6. Backfill over the final gravel layer must not be less than 24 inches. Insulation
shall be installed when the backfill depth is less than 36 inches. The finish grade
over the trench shall be mounded to prevent formation of depression after settling.
7. Insulation shall be placed over any wastewater line or pipe over which a driveway,
parking, or vehicle storage area may be constructed.
8. A minimum 2 foot of accepting soil is required below the drainfeld rock for a 5
foot wide trench. Contractor shall verify this condition prior to placement of the
rock. If course gravel or other unacceptable material is encountered, the contractor
shall inform the inspecting engineer for evaluation of accepting soil before
placement of drainfield rock.
