(b) Terminated by consent pursuant to NRS 445D.190;

(c) Terminated pursuant to subsection 2;

(d) Terminated by foreclosure of an interest that has priority over the environmental covenant; or

(e) Terminated or modified in an eminent domain proceeding, but only if:

(1) The agency that signed the covenant is a party to the proceeding;

(2) All persons identified in subsections 1 and 2 of NRS 445D.190 are given notice of the pendency of the proceeding; and

(3) The court determines, after hearing, that the termination or modification will not adversely affect human health or the environment.

4. An environmental covenant may not be extinguished, limited or impaired by application of any laws of this State relating to marketable title or dormant mineral interests.
