## Document text

(a) The basis and purpose of these rules is to describe the protection of and limited
access to customer data for gas utilities over which the Commission has
jurisdiction. These rules are applicable to all utilities except for certain provisions
as defined in the rule.
(b) For the purpose of the Customer Data Access and Privacy Rules, gas utilities are
classed into three tiers: a Tier I utility serves more than 150,000 gas customers;
a Tier II utility serves between 50,000 and 150,000 gas customers. A Tier III
utility serves fewer than 50,000 gas customers.
(c) No Tier III utility is required to:
(I) include in its tariffs a description of standard and non-standard customer
data that the utility is able to provide to the customer or to any third party
recipient (see paragraph 4027(c));
(II) provide customer notice each year regarding customer data (see rule
4028);
(III) make customer consent forms for the disclosure of customer data
available to customers or third parties (see rule 4029);
(IV) disclose aggregated data (see rule 4033); or
(V) provide a community energy report (see rule 4035).
However, a Tier III utility may include a description of standard and non-standard
customer data that the utility is able to provide to the customer or to any third-
party recipient in its tariffs (in accordance with paragraph 4027(c)). Commencing
upon the effective date of such description, the Tier III utility shall be deemed to
be a Tier II utility for purposes of these Customer Data Access and Privacy Rules
for so long as such tariff provisions remain in effect.
