Ref: Request for Well Waiver Amendment for Paradise Valley, Block 2, Lot 25,
To Deb Wockenfuss:
The referenced lot has many challenges and constraints due to the topography. The area we proposed to have
the well drilled was found to be virtually impossible to drill at. The owner of the property is doing everything
reasonable within his power to drill as far away from the proposed septic location as possible. This includes,
moving material around and constructing a retaining wall that would allow the drill rig to get further back of
the property. We are requesting you amend the well waiver already approved for 75 feet fi'om the proposed
well to the proposed drainfield reserve site area to 75 feet to include the proposed drainfield reserve site area
and the proposed primary drainfield and STEP tank. The following are mitigating factors for the justification
of the waiver:
We are proposing to use a MOA category III Nitrogen reducing Quanics Aerocell unit that will
produce an effluent meeting State of Alaska DEC secondary standards.
The system is an advanced treatment system which requires regular maintenance inspections. The
downhill slope will be inspected during each site visit.
Attached are two surrounding well logs. The well logs indicate that there is no shallow bedrock and
the soil strata consist of sand, gravel, & clays.
We were able to locate one water sample pulled in 1991 for Paradise Valley Block 2, Lot 27 and its
nitrates level was 1 o3 mg/Lo
A 75 foot waiver was already granted from the proposed well to the proposed drainfield reserve site
area.
I believe there is minimal risk associated with the grating of this waiver. See attached cross section drawing.
We are unaware of any adverse impacts this installation would have on adjacent wells or septic systems. If
you have any q~act us at 337-6179. Thank you for your assistance.

Ref: Revised Design: Well & Septic System for Paradise Valley, Block 2, Lot 25,
To Deb Wockenfuss:
We have previously submitted a design package for the referenced property and a permit has not been issued to
date. The owner has requested that we revise the design for the following reasons;
· The owner of the referenced property has recently re-graded his lot pushing the cutbank back.
· The house and its location have been re-platted.
· It was requested that we re-locate the proposed well location. The home owner informed us that he had met
with you and you advised him that because of the challenges he faces with steep slopes that he could apply
for a 75' waiver from the proposed well to the proposed septic system and/or proposed reserve site, so that
he could place his well in a more reasonable location°
The proposed 4 bedroom house is to be served by a private well and septic system. The topography of the lot
dictates that the new drainfield be installed on the south end of the property. We are proposing to install a
1500 gallon SoT.E.P. tank with Quanics control/floats, a 650 Aerocell unit, and a bed type drainfieldo Two test
holes were excavated on the property. The drainfield will be designed around the 30 foot radius of test hole
#1. Depending on the elevation of the plumbing from the house, a pump vault may be necessary to transfer
wastewater from the house to the STEP tank. Comments regarding the design are summarized as follows:
1. SOILS: See the attached logs which show the soil classifications, groundwater monitoring, and the
percolation test results°
2. DRAINFIELD DESIGN: See attached design drawing for drainfield specifications.
3. SURFACE WATERS: There are no surface waters within 100 feet of the proposed septic system.
4. TOPOGRAPHY AND WAIVER REQUEST: As can be seen on the attached design drawing, the
average topography below the drainfield is a 60+ percent slope, running approximately south to north. The
proposed drainfield is currently residing 32' away from the top of the cutbank. We are requesting a 32' waiver
be granted from the drainfield to the cutbank. As can be seen on the attached drawing, at a 25% slope (starting
2 feet above the invert of the drainfield) the potential point of daylighting is greater than 50' horizontally from
the bed. The following are mitigating factors for the justification of these waivers:
· We are proposing to use a MOA category III Nitrogen reducing Quanics Aerocell unit that will
produce an effluent meeting State of Alaska DEC secondary standards in regards to BODS/TSS.
Consequently, if effluent were to daylight, there is less potential for environmental impact~
· The system is an advanced treatment system which requires regular maintenance inspections. The
downhill slope will be inspected during each site visit.

Ph: (907) 337-6179 * Fax: (907) 338-3246 * Website: www.garnessengineering.com
· Given the porosity of the soil, there should be rapid downward migration and minimal lateral
migration of the effluent.
· The fill will be topsoiled and seeded to prevent erosion and inhibit surface daylightingo
· The slope is in a prominent location; therefore daylighting effluent will be immediately noted.
In short there is minimal risk associated with the grating of this waiver. See attached cross section drawing.
5. LOT LINE WAIVER REQUEST: We are requesting a 5 foot lot line waiver from both the proposed
drainfield to the south lot line and the reserve drainfield from the south & west lot lines°. Due to the limited
space and steep topography, placing the beds in the specified locations is the only viable optionsa The
following are mitigating factors for the justification of the waiver:
· We are proposing to use a MOA category III Nitrogen reducing Quanics Aerocell unit that will
produce an effluent meeting State of Alaska DEC secondary standards in regards to BODS/TSSo
Consequently, if effluent were to daylight, there is less potential for environmental impact°
· The system is an advanced treatment system which requires regular maintenance inspections. The
downhill slope will be inspected during each site visit.
· Given the porosity of the soil, there should be rapid downward migration and minimal lateral
migration of the effluent.
· There are no existing septic systems within 50 feet of the proposed drainfield or reserve site.
6. 75' WELL WAIVER REQUEST TO RESERVE SITE: Due to site constraints and the difficulties of
accessing areas where the well can meet the separation of both the proposed septic system and the reserve
drainfield site, we are requesting a 75' waiver be granted from the proposed well to the proposed reserve
drainfield site area. The following are mitigating factors for the justification of the waiver:
· We are proposing to use a MOA category III Nitrogen reducing Quanics Aerocell unit that will
produce an effluent meeting State of Alaska DEC secondary standards in regards to BODS/TSS
nitrate levels averaging less than 30 mg/L and fecal coliform levels averaging less than 20,000
Col/100 mL.
· The system is an advanced treatment system which requires regular maintenance inspections. The
downhill slope will be inspected during each site visit.
· Attached are two surrounding well logs. The well logs indicate that there is no shallow bedrock and
the soil strata consist of sand, gravel, & clays.
· We were able to locate one water sample pulled in 1991 for Paradise Valley Block 2, Lot 27 and its
nitrates level was 1~3 m~L.
In short there is minimal risk associated with the grating of this waiver. See attached cross section drawing.
~y adverse impacts this installation would have on adjacent wells or septic systems.

Comments: This investigation was completed in compliance with MOA guidelines, regulations,
and best industry practices / methods. The assessment of the condition of the well and septic
applies only to the conditions as of the day tested. The flow and absorption rates may change
due to subsurface conditions that may not be observed from the surface, changes in land use,
local soil characteristics, groundwater levels that may fluctuate during the year, quality of
construction (workmanship & materials), the water usage of the family being served by the
system and maintenance. The operational life of all well and septic systems are subject to
these various and dynamic characteristics and are outside the control of the evaluator of the
well and septic system. Therefore, any or NO estimate of how long a system will function satisfactory
for current or future occupants or guarantee that no unseen encroachments, deficiencies or
discrepancies exist can be given by First Water Consulting &
