V. ADDITIONAL REGIONAL STAFF REVIEW ITEMS
1- The facility lat-long is correct in BIMS.
2- The field center lat-long is correct in BIMS and the last permit.
3- The system was originally intended to serve a main house and a smaller building totaling 4 bedrooms.The second
"residence"was only built and used as a shed by the previous owners. However, it.looks like the current owner is
upgrading it a bit. I cautioned the current owner in an email,that the permit only covers 4 bedrooms.This should
be a future inspection item. It is not obvious whether a septic tank was ever installed for this out building.
4- RRO does not have the design diagrams.
5- Head locations were GPSed on 04/04/2017 by point averaging, and subject to the inherent problems with a
navigation grade unit working under canopy.
