Subject: Southpointe, Block 1, Lot 2 — NHN Southpointe Ridge
Septic System Design
Dear On -Site Services Engineer:
The owner of the above lot intends to build a 5 -bedroom home on the property. We are
submitting this permit application for the construction of a septic system. The attached site plan
identifies the location of the home and the existing well, proposed septic location and alternate
site. No conflicts exist between this proposed system and any other well or septic system on this
lot or adjacent lots.
The ground surface on the lot in the area of the absorption trenches slope to the northwest. The
absorption trench will be placed closer than 35' from slopes greater than 25%, but the trench
section has been designed to meet the steep slope provision of the ordinance. No waiver is
required. Contours are shown on the site plan indicating the grade and direction of flow. Storm
water drainage will not impact this septic system. The new trenches will be constructed parallel
to the slope as much as possible.
The absorption trench will be constructed partially in fill material. The material is clean gravel
with some silt and no organics or other debris. It is compacted to the same degree as the
underlying in situ material. The fill was placed during construction of the road more than 10
years ago. The percolation rate of the fill may be slower than the underlying in situ material.
We have use an application rate of 4 gallons per day per square foot which equates to a
percolation rate of up to 30 minutes per inch which is much slower than the in situ material.
Please refer to the attached test hole log and plan and profile sheets for the septic design. If this
design is followed, there will be no adverse impacts to adjacent properties.
Sincerely,
Michael E. Anderson, PE

Nitrate Advisory
Certificate of On‐Site Systems Approval # OSC201079
Subdivision: Southpointe, Block: 1, Lot: 2
A water sample revealed a nitrate concentration of 7.58 milligrams per liter (mg/L).
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. Since nitrates are known to slowly increase, we recommend
you monitor the water quality. 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.

Nitrate Fact Sheet
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 medi a 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.

Owner acknowledges that the Municipality may request records of maintenance and
repairs from the manufacturer's representative or maintenance provider.
Owner acknowledges that the fine for failing to maintain and repair an AWWTS may he
assessed in accordance with AIMC 14.60.030.
Ownrer agrees to grant the Municipality reasonable access to test and inspect the
AWNVTS. The Municipality will give at least 24-hour notice.
Owner agrees that any sale or transfer of title of the property will not occur without a new
} Certificate of On -Site Systems Approval.
Owner agrees that the AWWTS installation and maintenance requirements as provided
by the AWWTS vendor/installer and Approved by the Municipality are the governing
guidelines for the construction, maintenance and repair of the Owner's AWWTS.
Owner agrees to maintain remote monitoring of the AWWTS as required by the
AWWTS approval.
3. Term. The term of this Agreement shall begin on the date of approval by the
,lunicipality to operate the installed system, or upon transfer of title, and shall continue
while the AWWTS is operational or until title is transferred.
