Establishment of critical deposition and acidification levels—Considerations.
In establishing critical levels of acid deposition and lake, stream, and soil acidification, the department of ecology shall consider:
(1) Current acid deposition and lake, stream, and soil acidification levels;
(2) Changes in acid deposition and lake, stream, and soil acidification levels;
(3) Effects of acid deposition and lake, stream, and soil acidification on the environment; and
(4) The need to prevent environmental degradation.
