Allowing a Limited Alternative to Filtration in Regulation

The Public Comment period for this regulation is open from October 1, 2024 through November 9, 2024.

The Department of Environmental Conservation proposes to change regulations by allowing a limited alternative to filtration (LAF).

The Department of Environmental Conservation proposes to adopt regulation changes in 18 AAC 80 of the Alaska Administrative Code, allowing an alternative compliance option for some unfiltered surface water systems, including the following:

  1. adopt a new section 18 AAC 80.621 concerning limited alternative to filtration, approval, compliance requirements, and termination provisions that allow an owner of a public water system to apply for a "limited alternative to filtration" allowing source water to remain unfiltered; and
  2. amend 18 AAC 80.1990(a) by adopting definitions for "limited alternative to filtration" and "turbidity event."
