(a)   Each utility shall adopt the following periodic and routine test and repair schedule of its meters:

(1)   1 inch and smaller meters: 10-year interval between test years

(2)   1 ½ inch and 2 inch meters: 6-year interval between test years

(3)   3 inch meters: 4-year interval between test years

(4)   4 inch and larger meters: 2-year interval between test years

(b)   If the meters of a utility are maintained in compliance with the provisions of the schedule in (a) of this Section, and if at least ninety percent (90%) of the meters tested register an accuracy of not less than ninety-eight percent (98%) nor more than one hundred two percent (102%) during a three (3) year period, the utility, upon application and after notice and hearing, may be granted an extension in the time interval between test years.

(c)   If the water meter testing program of a utility does not meet the standards prescribed in subsection (b) of this Section over a three (3) year period, the time interval between test years may be reduced by the Commission after notice and hearing. Change in ownership or assets of the water utility shall not change the requirements for periodic testing of active meters being utilized by the utility.

(e)   All tolerances of this Chapter are to be interpreted as maximum permissible variations from the condition of zero (0) error. In making adjustments no advantage shall be taken of the prescribed tolerance limits.

(f)   The utility shall maintain a record of the most recent test of each meter.
