Environmental Covenant Tracking
A durable notification mechanism, such as an environmental covenant, is an instrument used to define the appropriate activities and/or uses on real property that has been subject to contamination. It is a recordable instrument that is attached to the deed and runs with the property. It is almost always used on a property that was subject to clean-up action by a regulatory authority, either the Nevada Division of Environmental Protection (NDEP) or the US Environmental Protection Agency (US EPA).
In 2005, environmental covenants were created with the passage of Senate Bill No. 263 by the Nevada Legislature and later codified in the Nevada Revised Statutes (NRS 445D). The covenants meet a need to protect both the responsible party and regulatory agencies. Responsible parties must invest significant resources for removing contamination and constructing and maintaining engineering controls to limit the potential exposure from remnant contamination. Regulatory agencies on the other hand, such as NDEP or the US EPA, are responsible for enforcing and overseeing clean-up actions to assure protections remain in-place and are effective through their design life.
One can learn more about Nevada's environmental covenants on this webpage. As of January 2012, this webpage contains links to allow individuals to locate properties throughout Nevada that have covenants attached to their property deeds.

(1) The Riverpark Sampling and Analysis Plan [21 page pdf, 697 kB] is a required document under the Carson River Mercury Site Long Term Sampling and Response Plan. It defines the sampling strategy and methodology used to characterize the potential mercury contamination with the Riverpark subdivision prior to [and subsequent of] residential development of the land. Requiring this document gives the Nevada Division of Environmental Protection the opportunity to review the land developer's sampling strategy and methods in order to assure that the data collected will be representative of site conditions and that final site conditions will be appropriately protective of human health and the environment.
