Dear Contractor:
I am writing in regards to your building project at 2920 Fox Street in the City of Orono.
On Thursday May 1 l, 2006 I noticed a contractor/excavator placing fill over the top of
the mound system. This was not the same company that had installed the septic system
to this point. The contractor placing the fill on the mound system is not a licensed septic
installer. This could be considered a violation of State Rules.
The fill being placed on the mound system was completely inappropriate. Minnesota
State Code Chapter 7080 calls for six inches of sandy to loamy soil be placed on the rock
bed to a depth of one foot in the center of the mound tapering to six inches at the sides
and then a minimum of six inches of topsoil borrow placed over the entire mound.
Topsoil borrow is defined as a loamy soil having adequate nutrients and pH to sustain
healthy plant growth. The material I witnessed being placed on the mound was heavy
wet clay that was coming from the lot itsel£ The soils native to the property are not
adequate for placement on the mound system.
I informed your installer of record that all the clay was be removed from the mound and
the appropriate materials be brouaht in after the rock bed and distribution laterals are
checked for damage. A certificate of occupancy will not be issued until the septic system
has had a final inspection. Please feel free to call with any questions you may have.
Sincerely,
����'�.,..�.�..���
