Grower: Scott Farm Site 4 Lagoon 3139 (C) Designed By: JEO
Address: PO Box 785 Checked By: DSE
Rose Hill, NC 28458 Date: 01/12/24
Countv: Duolin Sheet 7 of 7
This livestock waste treatment lagoon is designed in accordance with the United States
Natural Resources Conservation Service PRACTICE STANDARD 359- WASTE TREATMENT
LAGOON, revised prior to June, 1996.
Emergency Spillway:
An Emergency Spillway is not required.
NOTE: See attached Waste Utilization Plan
DESIGNED: �
DATE: 01/12/2024
COMMENTS: The lagoon has been designed as an irregular shape.
This design is update of start and stop pump elevations and to show the 1/2
treatment volume level for sludge storage. This design does not supercede the
original certification of the farm.
Elevations are based on an assumed benchmark and do not represent mean sea level datum.
1 certify, to the best of my professional knowledge, judgement, and belief, this design calculation
is in accordance with the applicable NRCS standards.
