V. ADDITIONAL REGIONAL STAFF REVIEW ITEMS
1- The facility lat-long is correct in BIMS.
2- The center of the field was estimated at 35.82477,-79.00669 from Google Earth. The spray field is mostly mowed
but extends slightly into the woods on the north and west sides.
3- The system only has one pump which handles both recirc and dosing. I checked this and verified it with the
contractor. Unfortunately, I do not know which of the two listed horsepowers is correct and it is not shown on the
design diagram. RRO records only go back to 2001 and do not include the original description in 1998. Also, the
facility description should reference 3 drip zones, (in contrast to 4 shown on the design diagram).
4- The house and treatment system locations moved east from the design map but the buffer distances are still OK.
The field is in the location shown on the design map.
5- Several maintenance issues led to NOD-2019-PC-0204. The contractor said that all issues have been addressed
and sent a picture of the new sand filter roof. A follow-up visit is planned for later this week. In any case, this
should not hold up permit issuance.
