Nevada Mercury Control Program (NMCP) - Annual Emissions Reporting
Pursuant to NMCP regulations, facilities must report mercury emissions annually. Mercury emissions are calculated for every thermal unit, which is not De Minimis, using the most recent NDEP-approved stack test emission factor with actual throughput (production) values for the year. Annual reports are received by the NDEP in the month of March, each year. The NDEP reviews the data submittals and aggregates the data into a spreadsheet report by July 1st, each year.

For the 2006 reporting year, not all thermal units had been stack tested for mercury emissions. Only Tier-1 units had the requirement to test prior to December 31, 2006; Tier-2 units began testing in the 2007 calendar year. Facilities which had not tested were instructed to use an emission factor from a similar unit in industry as a "surrogate emission factor." Later testing demonstrated that many of the surrogate values were quite different from tested values; thus the 2006 reported emission totals are coarse.
2007 Reporting Year [PDF] - Coming Soon...
For the 2007 reporting year, all thermal units were stack tested for mercury emissions, except De Minimis designated units. All units were tested with Method 29, except for a few individual units which used Method 101A. These source tests had NDEP-approved test protocols, NDEP-witnessed tests and NDEP-approved test results. Because every unit tested and had its own emission factor, the 2007 year offers the best emissions data resolution to date.
