RE: OSP191497 – IR – MOUNTAIN PARK ESTATES B8, L13
Per your inspection report comment and internal review with discussions with Mike N. Anderson,
P.E. – it has been determined that the existing portion of the field closest to the house is and has
functioned in compliance with code requirements for freeze protection and structural stability.
This portion was slightly adjusted because Kenneth Lang, RLS did not show the pipe and system
locations correctly.
The field in question is along the driveway is approximately 8’ from grade and the integrity and
functionality has not been impacted. The field is functioning and at this depth there is no adverse
effects. This is more of an approach area to the interior garage and a wood shed exists right in
front of this trench with little to no know vehicular traffic. There have been no known issues
freezing or otherwise with this trench.
We respectfully request approval of the inspection report previously submitted. The system has
been working for the occupants and will not or has not impacted any of the neighboring
properties or poses a public health risk. Please contact us if you have any questions.
Sincerely,
Curtis Huffman, P.E.

RE: NEW SEPTIC SYSTEM PERMIT
LEGAL: MOUNTAIN PARK ESTATES BLOCK 8, LOT 13
Weve been requested to obtain a septic permit on the above referenced lot to augment the
system by 2 bedrooms for a total of 5 bedrooms. We propose to install a 1500-gallon septic tank
with two additional trenches connected to the existing system as shown on the attached design.
The design is based on existing MOA record test holes conducted in 1990 which shows GM soils
to 15 and no groundwater. Per MOA records, the adjacent 4 properties show 0.6 0.8 GPD/SF
soils with field depths of 8-11.
The slopes are moderate at 7-15% at the proposed septic location. There has been some fill
(3+/-) along the Crestview Drive side of the property that makes the slopes appear steeper on
street view, but grades are less than 25% and complies with 15.65.210B.1.e. The lot and area are
served by private water. The design will not impact any of the neighboring properties. Please
contact Brent M. Western or me if you have any questions.
Sincerely,
Michael N. Anderson, P.E.

Re:
On-Site Sewer Permit f~90-0303 at Lot 13 Block 8 Mountain Park Estates
Subdivision for Kevin Kurka.
Dear Dan:
In accordance with our discussion at the site on August 3, 1992 we performed a
percolation test and prepared an updated site plan for the project. Please see the attached
calculation sheet for calculation of new soil rating used, and absorption requirements.
No real change in the system size is proposed. A slight modification to the system
alignment was required to fit the as-built trench position. It does not appear that the
driveway will conflict with the secondary system, nor does the septic system encroach on
the wells in the area.
Kevin stated that he came ha and renewed his septic permit, but has not come by to pick
it up yet. I have listed his old permit number at the top. Please call if you have any
questions.
Sincerely Yours

Re:
Susan Oswalt
On-Site Sewer As-Built at Lot 13 Block 8 Mountain Park Estates Subdivision for
Kevin Kurka.
Dear Susan:
The two percolation tests done at the site were done by two different parties in two
different layers or strata. The original design was made by Corwin, using a single test
between 3 to 4 feet rated at 14 minutes per inch. Upon yom' request of the owner,
confirmation of this was requested dm'ing his construction of the system because the soils
did not appear to be as good as indicated by the test. I conducted an additional test at the
bottom of the proposed system between 9 and 10 feet in the worst looking material. This
tested at 40 minutes per inch. The material appeared to change uniformly, with a higher
percentage of fines as the depth increased.
Using the additional test, I averaged the two tests per AO 90-48 Section 15.65.060.B.2.
I assumed that the areas were approximately equal. This value indicated an application
rate of 0.6 gpd/sq, ft., which was used to redesign the system. An additional 12.5 feet of
trench was required over the original design. Please call if you have any questions.

Starting at 20 years of age the MOA issues Advisory's for steel septic tanks. The septic tank for
this property is 27 years old. Typical replacement costs range from $6,000 to $9,000.
This advisory must be attached to all copies of the subject Certificate of On -Site Systems
Approval.
This is an example of what the metal of a 20 year old steel tank MAY look like.

Nitrate Advisory
Certificate of On -Site Systems Approval # OSC191402
Subdivision: Mountain Park Estates, Block: 8, Lot:13
A water sample revealed a nitrate concentration of 8.69 milligrams per liter
(mg/Q. The Environmental Protection Agency (EPA) has established a maximum
contaminant level (MCL) of 10.0 mg/L for public drinking water systems. While
private wells are not subject to this regulation, EPA standards are based on existing
health information and can therefore be used to gauge the relative quality of water
from private wells. Please see the attached "Nitrate Fact Sheet" for important
information regarding nitrate.
This advisory must be attached to all copies of the subject Certificate of On -Site
Systems Approval.

From Northern Testing Laboratories, Inc.
Nitrate is a negatively charged compound of nitrogen and oxygen, which is very soluble in water. Nitrate
is not readily filtered or otherwise removed in the soil and can pass rapidly into ground water wells.
SOURCE: Nitrate is a major component of fertilizer and wastewater. Often the nitrate is in the form of
ammonia or protein first, which through contact with oxygen and certain bacteria, converts to the
oxidized form known as nitrate. Sources of nitrate from wastewater include urea, ammonia cleaners,
food solids, and bacterial cells. It may also result from the breakdown of organic matter buried in the soil.
TOXICITY: Nitrate is generally not toxic to adults or children over the age of two or three years, but is
associated with a potentially fatal infant disease called methemoglobinemia. In the digestive system of
young children, nitrate converts to nitrite, which can pass through the intestinal wall into the blood
stream. There it combines with the hemoglobin and interferes with the ability of the blood to carry
oxygen. For this reason, methemoglobinemia is referred to as "blue baby" disease. The EPA limits the
concentration of nitrate in public drinking water supplies to 10 mg/L. The standard has been lowered
from a previous level of 45 mg/L set by the US Public Health Service and the World Health Organization.
TREATMENT: due to its solubility in water and negative ionic charge, filtration and other common home
water treatment systems such as softening or iron filtration does not readily remove nitrate. The best
method for limiting nitrate in well water is source control. This can include avoiding overdosing of
fertilizer near the well and maintaining good separation distances between septic tank leach fields and
the well. A special anion exchange filter that contains a media with a strong affinity for negatively charged
ions in water, or by a reverse osmosis treatment system or distillation can remove nitrate.
TESTING: Nitrate analysis is usually done by one of the several "wet chemical" methods using a
spectrophotometer to read the final color endpoint. Specific ion electrodes also can be used to detect
the activity of nitrate in water. This laboratory uses several different wet chemical methods approved
under the public water supply laboratory certification program. They also have test kits available, which
the laboratory uses to perform an inexpensive "screening test", and with which the homeowner can
monitor the change in nitrate levels from their well. They recommend comparing the test kit results
against a certified analysis from the lab occasionally to verify the accuracy of the kit. We recommend
using a specially prepared bottle that has been rinsed in hydrochloric acid for collecting samples.

Address of Camera Inspection: 13100 Alpine drive
Date: 8-30-19
During the camera inspection we found that the condition of the casing made it impossible to discern
weather any surface water or otherwise has been entering the borehole. The degredation of the casing
seemed somewhat normal at 110' but any casing shallower had some sort of white growths or barnacles
and random patterns of deposits. In order to make a conclusive determination of a casing breach, we
would need to have better visual of potential streaking or discolorations present on the pipe. Although
no active intrusion or running water was observed, we were unable to make any official determination.
