V. ADDITIONAL REGIONAL STAFF REVIEW ITEMS

Site inspection performed on 8/6/20. Met with owners and representative with McFarland Septic. System is well maintained.
McFarland services the system twice a year and comes out to make repairs as needed. On day of inspection, McFarland was
servicing the system which included replacing the UV bulbs. The owners take a lot of care in maintaining the drip fields. There
are 4 zones-two which are in grass and two which are in a wooded area. The grass is well maintained and the wooden area also
has a good vegetation. There is fencing around all of the drip zones. The amount of drip area (.52 acres) is large. Based on
conversations with the owners they are interested in trying to reduce the size of the drip area. RRO is not opposed to the id ea, but
told the owners that it would require a permit modification and some additional soils and engineering work. They expressed
interest in doing that after the permit renewal is completed. This system is well maintained and operated.
