Utah Admin. Code R315-101-3 - Principle of Non-degradation
(a) When
closing or managing a contaminated site that has been stabilized in accordance
with Section R315-101-2, the responsible
party shall, to the extent practicable in accordance with Subsection
R315-101-1(c),
not allow the mass of contaminants in the source area to increase. Levels of
contamination in groundwater, regardless of quality, shall not increase beyond
the existing levels of contamination at a site when the responsible party has
defined the nature and extent of contamination pursuant to Section
R315-101-4. Consideration will
be given to naturally occurring variations in groundwater contaminant
concentrations, natural groundwater flow, and dispersion.
(b) The responsible party shall demonstrate
compliance with Subsection
R315-101-3(a)
by submitting appropriate sampling or other data as may be required by the
director.
(c) If at any time the
level of contamination increases to a significant level, as determined by the
director on a case-by-case basis, the responsible party shall take action, as
determined by the director, such as source removal or source control, to
prevent further degradation of groundwater. A work plan addressing interim
action or other corrective action to mitigate the situation shall be submitted
to the director for review and approval.
