(2) Small System Variances Availability.
(a) A small system variance is not available under 310 CMR 22.13A for a national primary
drinking water regulation for a microbial contaminant (including a bacterium, Virus, or other
organism) or an indicator or Treatment Technique for a microbial contaminant.
(b) A small system variance under 310 CMR 22.13A is otherwise only available for
compliance with the requirement specifying a Maximum Contaminant Level or Treatment
Technique for a contaminant with respect to which;
1. a national primary drinking water regulations was promulgated on or after
January 1, 1986; and

(b) If the Department is proposing to grant a small system variance to a Public Water
System serving 3,300 or fewer persons and the Administrator objects to the small system
variance, the date on which the Department makes the recommended modifications or
responds in writing to each objection; or
(c) If the Department is proposing to grant a small system variance to a Public Water
System serving a population more than 3,300 and fewer than 10,000 persons, the date the
Administrator must approve or disapprove the variance within 90 days after it is submitted
to the Administrator for review.
(4) Review of Small System Variance Applications.
(a) A Public Water System requesting a small system variance must provide accurate and
correct information to the Department or the Administrator to issue a small system variance

22.13A(1) and (2).
2. The Small Water System cannot afford to comply, in accordance with affordability
criteria established by the Department, with the national primary drinking water
regulations for which a small system variance is sought, including by:
a. Treatment;

4. compliance with the terms and conditions of the small system variance as soon as
practicable but not later than three years after the date on which the small system
variance is granted. The Administrator or the Department may allow up to two
additional years in the Administrator of the Department determines that additional time
is necessary for the Public Water System to;
a. complete necessary capital improvements to comply with small system variance
technology, secure an alternative source of water or restructure or consolidate; or
