Dear Mr. Cowan:
This office issued permit #SW990215 for the subject property on July 26, 1999. Upon receiving
conflicting information regarding the number of dwelling units on this property, this permit has
been rescinded.
Both you and Mr. Robert Shafer have stated to me that the structure has a kitchen, bathrooms
and bedrooms in both the upstairs and downstairs areas of this building. Also, no access exists
within the structure between these two sections.
Both you and I have discussed this matter with my supervisor, Jim Cross and the Environmental
Services Division Manager, Lura Morgan. This letter is to confirm the decisions made during
these conversations.
Due to the conflicting information on the number of dwelling units, the Department of Health
and Human Services will not reinstate permit #SW990215 without the following: An evaluation
based on a site inspection from either the Municipality of Anchorage Department of Public
Works or Municipality of Anchorage Property Appraisal stating that the property is a single
family residence with one dwelling unit.
If this structure is determined to be a multi-family dwelling, you should contact the State of
Alaska Department of Environmental Conservation because multi-family wastewater disposal
systems and wells are under ADEC jurisdiction.
If you have any further comments or questions please contact me at 343-4728.
Sincerely,
Donna C. Mears

REFERENCE: Lot 3, Tract 10, Baumer S/D
Request you issue a permit to install a septic system to serve the existing five
bedroom dwelling on the referenced property, and issue a waiver of 25 feet to a
slope over 25%. The old system located in the slope will intersect any subsurface
migration, and the slope does not show any signs of effluent surfacing, even though
the old system has failed.
Two test holes were excavated and percolation tests performed. The approximate
location of the test holes are located on the attached site plan.
At the time of excavation, 7-7-99 water was found at 10 feet. After seven days of
ground water monitoring, water was found at 9 feet.
We do not anticipate any adverse effects on neighboring wells, septic systems, reserve
areas or drainage patterns by the installation of the proposed septic system. The
construction of this system will not prevent any future development on any of the
adjacent properties.
If you require additional information, please contact us.
Sincerely,
Robert C. Cowan, P.E.

ON-SITE WASTEWATER DISPOSAL SYSTEM
CONSTRUCTION PRACTICES
and
MATERIAL SPECIFICATIONS
REFERENCE: Lot 3, Tract 10, Baumer
July 21, 1999
GENERAL:
The scope of this project includes the installation of a 1500 gallon septic tank and
leachfield trench for the existing five bedroom house located on the referenced property.
Construction shall be in accordance with the approved site plan and design drawings,
Municipal permit with any special provisions or conditions, and all applicable State and
Municipal Wastewater Disposal Regulations.
The contractor shall be responsible for obtaining any necessary underground utility
locates.
Unless specifically agreed otherwise, the property owner shall be responsible for final
grading areas subsequently depressed from soil settling.
Contractors installing wastewater disposal systems must be certified by the Municipal
Health Department for system installations. Owners installing their own systems must
also receive prior approval from the Municipal Health Department.
SEPTIC TANK INSTALLATION:
A septic tank is to be constructed by a certified septic tank manufacturer. Construction
shall include two 4" cleanouts for pumping access.
The septic tank shall be sufficiently bedded to prevent settling or shifting of the tank.
All standpipes on the septic tank shall extend a minimum of 12 inches above final
grade.
Page 2
Lot 3, Tract 10, Baumer
July 21, 1999
Septic tanks installed with less than 4 fi. of cover shall be insulated.
A foundation cleanout shall be installed one to four feet from the building foundation.
In the line between the tank and the leachfield there shall be two adjacent cleanouts
(unless an effluent pumping system exists within the septic tank). These cleanouts shall
be located on undisturbed soil not more than 10 fl. from the tank. The first cleanout, in
line, shall be to clean toward the leachfield. The second cleanout shall be to clean
toward the septic tank.
Final grading over the septic tank shall be such that a positive slope exists away fi:om
the septic tank.
ABSORPTION TRENCH/DRAINFIELD INSTALLATION:
Excavate the proposed trench to the dimensions shown on the design. The bottom of
the excavation shall be within 2 inches of level. If the sidewalls of the excavation
become smeared, they must be raked or scratched (ruffed-up) before gravel (sewer rock)
placement.
Once the gravel is installed, the distribution pipe is to be installed level with the
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.
A sir barrier must be installed between the final gravel layer and the native soil backfill.
Ensure the silt barrier covers the entire gravel surface before placing backfill.
Monitor tubes shall be of four (4) inch diameter, installed approximately in the
locations shown on the design, and extend a minimum of 12 inches above final grade.
The portion of the monitoring tube extending through the gravel shall be perforated
f~om the bottom of the trench to the invert of the distribution pipe. This is equivalent to
the effective depth of the gravel as noted on the design.
Backfill over the final gravel layer must not be less than twenty-four (24) inches.
Insulation must be installed when the backfill depth is less than thirty-six (36) inches.
The finish grade over the trench must be mounded to prevent the formation of a
depression after settling.
Page 3
Lot 3, Tract 10, Baumer
July 21, 1999
MINIMUM MATERIAL SPECIFICATIONS:
Any septic tartk proposed for installation must be constructed by a Municipal approved
septic tank manufacturer.
The following pipe materials are approved for use in septic system installations in the
Municipality of Anchorage:
Type of Pipe Perforated .Solid
Cast Iron Yes Yes
ASTM D3034 (PVC) Yes Yes
ASTM F810 (HDPE) Yes No
ASTM D2662 (ABS) Yes Yes
Use of a type of pipe other than listed above must be approved by the inspecting
engineer.
Insulation shall be at least 2" thick extruded direct burial polystyrene (Dow Chemical
Company Styrofoam HI or equal).
Septic tank inlets and outlets shall be fitted with watertight couplings (Caulder, Fernco,
or equal).
A permeable nontoxic silt barrier (Typar 3401, Mirafi 140N, or equal) must be installed
between the final leachfield gravel layer and the native soil backfill.
All leachfield gravel (sewer rock) shall be 0.5"-2.5" screened gravel with less than 3%
passing the #200 sieve.
When sand is being used as a filter material, its gradation specifications must conform
to current M.O.A. or D.E.C. requirements, which ever requirement applies.
INSPECTIONS:
Typically there will be a minimum of three (3) inspections required during the installation of
the wastewater disposal system. These inspections will occur as follows:
Page 4
Lot 3, Tract 10, Baumer
July 21, 1999
The first inspection must be conducted after the excavation of ditches, pits,
trenches, or beds and before the installation of any gravel. A septic tank may be
set in place, but may not be backfilled before this inspection.
The second inspection must be conducted after the placement of the silt barrier,
gravel, distribution lines, standpipes, cleanouts, and insulation, but before the
placement of any other backfill.
3. The final inspection is to occur upon final grading of the property.
Often there will be more than these 3 inspections required. Especially with the installation of
multiple trenches, sand filters, pressurized distribution systems, etc. Thus, the inspecting
engineer is to be contacted at least 24 hours prior to the start of construction. If necessary, a
pre-construction meeting will take place on-site. The inspecting engineer will not coordinate,
direct or control in any way the contractors activities.
The owner shall contract with the contractor to perform the work outlined in these
specifications and plans and in accordance with the attached M.O.A. permit. There will be no
contractual arrangement existing between the contractor and S & S Engineering. S & S
Engineering shall be the owner's representative and will inspect the work as stated above to
document the contractors activities. Final acceptance of the contractors work rests with the
owner and the M.O.A.
S & S Engineering shall have no liability to the owner or to others for acts or omissions of the
contractor or any other persons performing work on this project or the failure of the contractor
to carry out the work in accordance with these construction documents. S & S Engineering's
inspecting engineer will not be responsible for the construction means, methods, techniques,
sequence, procedures or the safety precautions incident to this project.
