				  underground storage tank systems regulated under
				  15A NCAC
				  02N:
(i)
				  with secondary containment 50 feet
(ii) without secondary containment 100
				  feet
(T) Above ground or
				  underground storage tanks that contain petroleum fuels used for heating

(3) For a water supply well as defined in
				  G.S.
				  87-85(13) on a lot serving a
				  single-family dwelling and intended for domestic use, where lot size or other
				  fixed conditions preclude the separation distances specified in Subparagraph

(B) Animal barns 50 feet
(4) In addition to the separation distances
				  specified in Subparagraph (a)(2) of this Rule, a well or well system with a
				  designed capacity of 100,000 gallons per day (GPD) or greater shall be located
				  a sufficient distance from known or anticipated sources of groundwater
				  contamination so as to prevent a violation of groundwater quality standards
				  specified in
				  15A NCAC
				  02L .0202 resulting from the movement of
				  contaminants in response to the operation of the well or well system at the
				  proposed rate and schedule of pumping.
(5) Wells drilled for public water supply
				  systems regulated by the Public Water Supply Section of the Division of Water
				  Resources shall meet the requirements of
				  15A NCAC
				  18C.
