"Designations" references the De Minimis designations and "Issued Permits" references the Phase-1 and Phase-2 Mercury Operating Permits to Construct. The designations and issued permits are available in PDF format below. Please note that only the designations and permits are included here; the supporting documentation and data are available at the NDEP office or upon formal request.

View De Minimis Designations
Units which receive a De Minimis designation are not required to add control technology for the reduction of mercury emissions pursuant to NvMACT. The De Minimis mercury emissions level is 5 lbs/yr per facility. A facility may select the units of its choice, whose total combined mercury emissions are less than or equal to 5 lbs/yr. Units may not be considered De Minimis if they utilize a control for the reduction of mercury emissions. In this manner, a facility can not make a large-emitting unit De Minimis by adding a control technology. De Minimis is intended only for the smallest of emitting units. De Minimis potential to emit is calculated based on maximum operation scenarios utilizing stack tests or material assay data to calculate emissions. The majority of De Minimis units are laboratory equipment such as hotplates, drying ovens and spectrometers.

It is important to note that De Minimis units are not "out" of the Nevada Mercury Control Program. Facilities must demonstrate annually that their De Minimis units have not changed and that De Minimis emissions have not exceeded the 5lbs/yr threshold.
