(1) 2013 natural gas number for Glover was amended to reflect usage not previously reported.
(2) 2013 petroleum fuel was misreported for the Resource Recycling. Correction is shown here.
(3) Overall reduction in the 2014 total is due to the closure of the Herculaneum smelter.
(4) 2014 petroleum fuel increase is due to increased water pumping efforts, longer haul routes, and increased production for the Southeast Missouri Mining and Milling operation.

Total582,800(2)616,500(2)464,100(4)

(1) Difference in yearly figures reflects a temporary shutdown at the Herculaneum primary smelter caused by an electrical fire.
(2) In previous reports, explosives numbers reported were in pounds. This has been corrected to reflect metric tons.
(3) Difference in data from 2013 report reflects more accurate data collection.
(4) Overall reduction in the 2014 total is due to the closure of the Herculaneum smelter.

(1) Difference in yearly figures reflects process changes at Resource Recycling.
(2) 2013 adds copper not previously reported for Resource Recycling. Previous years were not adjusted.
(3) 2013 stack test for the Herculaneum primary smelter was unrepresentative. Previous stack tests were used to correct previously reported 2013 data.
(4) Overall, 2014 fugitive air emission reductions are related to the closure of the Herculaneum smelter, and Secondary Lead Smelting MACT updates at Resource Recycling.
(5) 2012 HAP data was misreported. Data has been corrected.
