FindingPurpose1994 c 281: "The legislature finds that chemical additives do, and that other types of additives may, contribute to septic system failure and groundwater contamination.

The purpose of this act is: (1) To establish a timely and orderly procedure for review and approval of on-site sewage disposal system additives; (2) to prohibit the use, sale, or distribution of additives having an adverse effect on public health or the water quality of the state; (3) to require the disclosure of the contents of additives that are advertised, sold, or distributed in the state; and (4) to provide for consumer protection." [ 1994 c 281 § 1.]
