Existing facilities which may cause or threaten to cause
environmental pollution within the limits of the City's wellfields'
recharge areas, which include but are not limited to those sites set
forth in the contaminant inventory detail which was developed in conjunction
with the preparation of the City's wellhead protection plan and which
is adopted by reference, and underground storage tanks which may affect
groundwater.

from which groundwater flows away at right angles in both directions.

surface.

water supply. The City may require an application to install one or
more groundwater monitoring well(s) at the expense of the applicant;
(b) The establishment of safety structures to prevent groundwater contamination;
(c) The establishment of an operational safety plan to define processes
and procedures for material containment, operations monitoring, best
management practices, and stormwater runoff management to prevent
groundwater contamination;
(d) Written policies and procedures for reporting and cleaning up any
spill of a hazardous material;

evaluation expense, if required by the City or its designee.
Nonconforming uses lawfully in existence within the Groundwater Protection Overlay District at the adoption of this chapter creating this district may continue to exist in the form and scope in which they existed at that time, subject to the provisions of Article
VIII. In the event a lawful nonconforming use poses a direct hazard to the City's public water supply, the City may take any action permitted by law to abate the hazard.
Nothing in this section shall be construed to imply that the
City has accepted any of an owner or operator's liability if a facility
or use, whether permitted as of right or pursuant to a conditional
use permit, contaminates groundwater in any aquifer.
