General Statute 143-215.1 and in a manner approved by the North Carolina Division of
Environmental Management
8. A usable reserve area shall be maintained for wastewater disposal. The reserve area shall
have the capability of accommodating the average daily flow of the facility being served
without exceeding the loading rates of the reserve area while meeting all required buffer
requirements.
9. Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.
10. The following buffers shall be maintained:
a) 100 feet between disposal area and any public or private water supply including
wells

c) 50 feet between disposal area and any stream, lake, river or natural drainageway
d) 50 feet between disposal area and property lines
e) 10 feet between disposal area and surface water interceptor drains or diversions
(upslope)
f) 25 feet between disposal area and surface water interceptor drains or diversions
(downslope) and groundwater drainage systems.

exfiltration occurs at a rate which does not exceed twenty (20) gallons per twenty-four (24)
hour per 1,000 gallons of tank capacity. The engineer's certification will serve as proof of
compliance with this condition.
MEWn woumv v i► :al u: a ►:► C : u
