Dear Mr. Shafer:
The Department has rewewed the information received in this office March 11, 1993,
regarding the above subject which included a letter describing the current state of the
system, a letter to the Municipality of Anchorage for a proposed septic upgrade serving
the single family home, and a set of drawings for the proposed upgrades. From the
information submitted and a review of this, office's files concerning this property the
Department has tho. fol}owi"~ comments'
w,,-,-- ;ter Disposal System:
T'..~ provlous history of this site has illustrated mat uu~ ...... ~,~ "' ??!!:, f?-¥"'., -
groundwater levels, and lot slope the present conventional on-site wastewater disposal
system is prone to failure. In addition, the limited area of the property prevents the
installation of an appropriately sized leachfield for the given facility size. Therefore, in
accordance with State Wastewater Disposal Regulations (18 AAC 72) approval for the
installation of a wastewater holding tank at the proposed location is granted by this
Department subject to the following conditions:
1. Submittal of an as-built of the wastewater holding tank system under the
stamp of a registered Professional Engineer (P.E.) to verify soils, watertable
and impermeable strata separation.
2. Installation of a dual alarm system for th3 holding tank and regularly
scheduled pumping of the tank.
3. Existing leachfield is to be abandoned as proposed along with effluent lines
from the septic tank.

The proposed location of the new Class "C" well appears to meet the concerns of this
Department. Therefore, in accordance with State Drinking Water Regulations (18 AAC 80)
approval to construct the well is granted. Enclosed is a Construction and Operation
Certificate with a si(~ned "AeDroval to Construct" ~,oproval to operate will be granted
based upon the following conditions:
Verification that the existing well is abandoned according to DEC
recommended guidelines.
2. Location of the well in longitude and latitude.

Dear Ms. Oswalt:
I have completed my review of the information that you faxed to me on July 21, 1992 and
the information submitted to this Department on the above-referenced property by Mr.
Waterfield, P.E. I have the following comments:
Based on as-builts submitted on June 26, 1992, there are no less than five
violations of State Separation Distance Regulations, they are as follows:
a)
On-site Public Water Source Well to septic tank serving three
bedroom house is less than the minimum 200 feet required by
18 AAC 80.
b)
On-site Public Water Source Well to Sewer line from the above
mentioned septic tank is less than the minimum 100 feet
required by 18 AAC 80.
c) On-site Public Water Source Well to foundation drain
discharge point.
d)
Public Water System Source Well on Lot 2, Block 1 to septic
tank for multi-family residence is less than the 150 feet
required by 18 AAC 80.
e)
Public Water System Source Well on Lot 2, Block I and the
foundation drain discharge for the multi-family residence.
~ pC hired on recycled paper
Susan Oswalt
2 July 30, 1992
The Public Water System Source Well and the Wastewater Disposal System
serving the multi-family residence were installed without written approval of
engineering plans. This is in violation at 18 AAC 72.210 and 18 AAC
80.300.
Based on the site inspection by Departmental staff, it appears that the
wastewater disposal system serving the multi-family residence has failed.
This is documented in a Departmental letter, dated July 14, 1992, of which
you received a copy.
During a July 15, 1992 inspection, I was able to locate a spring within 100
feet of the soil absorption system serving the single family residence.
If no wastewater was entering the soil absorption system (SAS) serving the
multi-family residence during my July 15, 1992 inspection, there appears to
be a spring along the toe at the soil absorption system near Berryhill Road.
6. The installed sand filter can not function as an intermittent sand filter.
The owner of the Class "C" Public Water System on Lot 2, Block 1, Valley
View Estates Subdivision #1, was not aware of the separation distance
problem between their source well and the septic tank serving the multi-
family residence on Lot 1, Block 1. Based on the conversation I had
concerning a new well for Lot 2, they may not issue or grant a letter of non-
objection for the lesser separation distance. If this holds, a waiver will not
be granted. As a result, the septic tank will need to be relocated outside
the 150' lost protective radius at the source well located on Lot 2, Blook 1.
This may include the foundation drain discharge.
Over all, I can not endorse the requested zoning variance (Case #92-060) and Preliminary
Plat Application (S-9279) until the Department's Notice of Violation is resolved. In
addition, I have enclosed a copy of the submitted information on the Public Water and
Wastewater Disposal System for your review and files.
Thank you for the opportunity to review this Zoning Variance/Preliminary Plat Application.
If you have questions, please do no hesitate to contact me at 349-7755.

Dear Mr. Waterfield:
This is in response to your June 26, 1992 submittal, which included a set of as-built
drawings of two wastewater disposal systems serving a single family and a multi-family
located on the above-referenced property. As stated in a Departmental letter to Mr.
Harold Tobey, your client, the submitted plans are incomplete. In addition, the
wastewater disposal system serving the multi-family residence was installed without first
obtaining written department approval to construct which is a violation of 18 AAC 72.210,
Wastewater Disposal.
As a result of the above noted problem with the submitted plans and the fact that the
wastewater disposal system has failed, and also based on recent inspections, I will not
conduct a complete review of the submitted plans. A set of engineering plans is required
covering the needed upgrades to bring the existing wastewater disposal system into
compliance with State Wastewater Disposal Regulations. The requested plans will need
to be submitted within 10 days of receipt of this letter.
In regards to the existing Class A Public Water System, it also was installed without
obtaining written approval of engineering plans prior to installation. This is in violation of
18 AAC 80.300 (a). Before any type of approval can be issued, items noted in 18 AAC
80.310 will need to be submitted to this office under the stamp of a Professional Engineer.
If you have any questions, please do not hesitate to contact me.

After the lift station pump was turned on, I saw wastewater bubbling up to the surface
of the land in at least two locations along the toe or side of the soil absorption system:
the first near the driveway entrance where I could hear the lift station pump running,
with wastewater bubbling up and running down the driveway and along the road; the
second was a far greater discharge volume from the toe of the absorption bed
adjacent to the lift station pump.
After making these observations, I asked you to take the following steps to reduce the
health hazard from the surfacing sewage:
pump the septic tank and pump the tank on an as needed basis until the
system is repaired using a septic tank pumping and hauling firm;
2.) temporarily operate the septic tank as a holding tank;
3,)
5.)
turn the lift station off;
submit engineering plans and soils tests for repair or replacement of the soil
absorption system to the Anchorage District Office of the DEC for review and
approval prior to construction of the repairs;
immediately apply bleach to the areas contaminated with surfacing wastewater
to provide immediate disinfection;
6.) in order to provide long term treatment and disinfection of the areas
contaminated with wastewater, within twenty four hours, you were asked to
apply lime to the areas contaminated with surfacing wastewater.
As we discussed, I collected samples of the ponded wastewater for laboratory
analysis.
The possibility exists that during the backfill or covering of the absorption system, the
pipes were inadvertently separated or damaged. As a suggestion, you might be able
to effect repairs to the existing system by carefully excavating the connections
between the lift station and the manifold in the soil absorption system and also by
looking at the end of the lateral leach line nearest the driveway entrance. I suggest
you have a professional engineer present if you intend to dig up the installed system
to assist you in documenting the problems with the existing system.
Please contact the Anchorage District Office of the DEC at least 48 hours in advance
of excavation, at 349-7755, to coordinate an inspection of the system excavation and
repairs.

Dear Mr. Tobey:
Re:
Lot 1, Block 1, Valley View Estates Addition #1, 10 bedroom four-plex on site
wastewater disposal system and Class A water System.
On Friday, June 26, 1992, the Anchorage District Office of the Department of
Environmental Conservation received an incomplete set of as-built plans for the
wastewater disposal systems constructed on Lot 1, Block 1 Valley View Estates
Addition #1 in September, 1991. The plans lacked a plan view layout of the soil
absorption system. In addition, a review of the DEC files indicates approval was not
obtained from the DEC prior to construction of the wastewater disposal system.
WASTEWATER DISPOSAL SYSTEM
On Monday, June 29, 1992, I met with you and your engineers at the subject property
to discuss the failing wastewater disposal system for your four-plex and single family
home.
As I drove up to the four-plex, I observed a water stain in the gravel road, extending
approximately 200 feet down the road from your lot. When I got out of the car, I
smelled the odor of wastewater and saw puddles of wastewater on the surface of the
driveway. I saw seeps coming from the side of the soil absorption system which
looked suspiciously like wastewater seeps, since I observed an algae growing on the
soils in the vicinity of the seeps.
Harold Tobey
July 14, 1992
In the event the absorption system is not repairable with the above mentioned
suggestions, you should have a professional engineer conduct several excavations
and perform soil tests to determine the nature and absorptive capacity of the
subsurface soils so they can properly size a soil absorption system to serve your
buildings. Once the soils have been evaluated, your engineer should be able to
design a system appropriate for your building to submit to the DEC for review and
approval prior to construction.
DRINKING WATER SYSTEM
After further review of the information submitted by your professional engineer, Mr.
Henry Waterfietd, I noted the septic tank serving the single family home is located
within the 150 foot protective radius from the public water supply well depicted as a
Class C well. Since the well serves thirteen bedrooms, one more than normally
considered a Class C service, the well should be classified as a Class A public water
supply well with a 200 foot protective radius. The protective radii are set out in 18
AAC 80.030(a) Table A.
You may apply for approval of a lesser separation distance than set out in Table A as
provided by 18 AAC 80.030 (b) 1 through 4, but I suggest you discuss this option with
Mr. Kleweno of the Anchorage District Office prior to expending funds on the waiver
request.
It also appears your public water supply well was drilled on 7/13/91, without benefit of
approval of engineering plans by the Department of Environmental Conservation as
required by 18 AAC 80.300.
You are required to obtain approval of design plans from the DEC prior to
construction of a new water supply well or wastewater disposal system. Approval of
plans by the DEC typically consists of: a signed construction portion of a construction
and operation certificate for water supply wells; and for wastewater disposal systems a
signed letter of approval to construct.
