2. Owner's responsibility for service measured through a shared meter.
(a) An owner shall eliminate any shared meter condition or, in the
alternative, establish an account in the owner's name for all the shared
area charges for service measured through a shared meter effective six
years prior to the discovery of or determination that a shared meter
condition exists, or the first day of the tenancy, or the date the
shared meter condition began, or the sixtieth day after the owner knew
or should have known that third party involvement exists, or the date
the owner assumed title to the dwelling, whichever is most recent in
time and for all future service measured by the shared meter. The
utility shall, upon an owner's application, open such an account and
bill the owner for all applicable shared area charges and all future
service measured by the shared meter through such account.
(b) (i) In the event that a legal impediment or extraordinary cost
prevents elimination of a shared meter condition or in the event that
the service measured through the shared meter is minimal, under
commission rules adopted, pursuant to subdivision eight of this section,
the owner, as an alternative to eliminating the shared meter condition,
may enter into a mutually acceptable written agreement with the shared
meter customer and where applicable, a third party, for apportioning the
charges for service measured through the shared meter; provided,
however, that the shared meter customer shall pay only for the estimated
amount of service provided to the shared meter customer's dwelling, or
