Utah Admin. Code R311-211-7 - Significance Level
(1) Where
contamination is identified that is below applicable MCLs, water classification
standards, or air quality standards or where applicable standards do not exist
for either the parameter in question or the environmental media in which the
contamination is found, the cleanup standard shall be established using Section
R311-211-3
and will be set between background and the observed level of contamination.
Should it be determined that the observed level of contamination will be
allowed to remain, this becomes the significance level.
(2) At any time, should continued monitoring
identify contamination above the significance level, the criteria of Section
R311-211-3
will be reapplied in connection with Section
R311-211-4
to re-evaluate the need for corrective action and determine an appropriate
cleanup standard.
