Wastewater System
Dear Mr. Garness:
On June 12 the department received a plan submittal for an onlot wastewater treatment system
with,a new 2,000 gallon septic tank and a new soil absorption system(15 'x 70' bed type)with
sand liner was designed for a 5 bedroom system at the above location. The installation has
followed this design even though the present use may be less.
We have talked concerning the design and by your most resent faxed information,the property
lines have been altered and the system shown for the 4 bedroom home is now located beyond the
class C well radius of 150 feet.
The new 2000 Ballon septic tank and the onsite soil absorption system, which is in a poorly
graded gravelly sand material that field tested at a percolation rate much faster than 1 minute per
inch(5 minutes to drop 6 inches).
The Department has reviewed the engineering plans submitted for the subject project and per the
Wastewater Regulations 18 AAC 72.240 approval to operate is hereby issued. A completed"Certificate
to Construct" for the wastewater system is enclosed. please request plan approval on these er designs Qom,
when the owner requests an increase in the size.
This approval does not imply the granting of additional authorizations nor obligate any state,
federal or local regulatory body to grant required authorizations.
Any person who disagrees with this decision may request an adjudicatory hearing in accordance
with 18 AAC 15.195- 18 AAC 15.340 or an informal review by the Division Director in //X4-;
accordance with 18 AAC 15.185.Informal review requests must be delivered to the Division
