Mississippi Code
Chapter 23 - Mississippi Uniform Environmental Covenants Act
§ 89-23-9. Validity of environmental covenant; effect on other instruments

An environmental covenant that complies with this chapter runs with the land.
An environmental covenant that is otherwise effective is valid and enforceable even if:
An instrument that creates restrictions or obligations with respect to real property that would qualify as activity and use limitations except for the fact that the instrument was recorded before July 1, 2008, is not invalid or unenforceable because of any of the limitations on enforcement of interests described in subsection (b) or because it was identified as an easement, servitude, deed restriction, or other interest. This chapter does not apply in any other respect to such an instrument.
This chapter does not invalidate or render unenforceable any interest, whether designated as an environmental covenant or other interest, that is otherwise enforceable under the law of this state.
