1. The Commission may grant an exemption from
any requirement respecting a maximum contaminant level or treatment technique
of an applicable primary drinking water regulation to:
(a) A public water system which was in
operation on the effective date of the requirement if:
(1) Because of compelling factors, including
economic considerations, such as qualification of the public water system as
serving a disadvantaged community, the public water system is unable to comply
or to implement measures to develop an alternative source of supply;
(2) The granting of the exemption will not
result in an unreasonable risk to health; and
(3) Management or restructuring changes, or
both, cannot reasonably be made that will result in compliance with the primary
drinking water standards or, if compliance cannot be achieved, improve the
quality of the drinking water; or
(b) A public water system which was not in
operation on the effective date of the requirement if:
(1) Because of compelling factors, including
economic considerations, such as qualification of the public water system as
serving a disadvantaged community, the public water system is unable to comply
or to implement measures to develop an alternative source of supply;
(2) There is no reasonable alternative source
of drinking water available to the public water system;
(3) The granting of the exemption will not
result in an unreasonable risk to health; and
(4) Management or restructuring changes, or
both, cannot reasonably be made that will result in compliance with the primary
drinking water standards or, if compliance cannot be achieved, improve the
quality of the drinking water.
2. Public hearings and other procedures for
consideration of requests for exemptions from NAC 445A.450 to 445A.5405,
inclusive, must be conducted in accordance with the procedures for seeking
variances from the Commission.
