OXIDES OF SULFUR ANNUAL EMISSION REPORTCompany NameGraymont Western US IncorporatedSite NameCricket Mountain PlantCompany ID- 1871Site ID -10313NOTE: Be aware that this report uses different methods of calculating emissions than are required forthe 2006 Emissions Inventory.Amount119981306 151/51 30501604 Yes 71 331122006 (using 1998method ofcalculation)1306 151/51 30501604 Yes 71781432006 (if methodof calculation isdifferent from1998)1306 151/51 30501604 Yes 717814Amount119981307 152/52 30501604 Yes 72 276422006 (using 1998method ofcalculation)1307 152/52 30501604 Yes 727632This form is to be used by sources that have emitted 100 tons or more of SOx in any calendar year after 1999, and that arenot subjectto acid raincontinuous monitoring reporting requirements (40CFRPart 75). Row 1 in the following table(s) contains historical inventory data for the listed component.Row 2 is used to calculate the 2006 process emissions using the same method that was used in the historical data. The inputs required are in green font.To insert the new data you type over the top of theold data. Row 3 (shaded) is used to show and calculate any changes in the method of calculation from1998 to 2006 (i.g. emission factors, % of sulfur, heating value, controls, breakdowns, estimation methods). If the current method of calculating the SOxemissions does not work with the equation providedin row 3, the calculation should be provided in therow 4. Rows 3 and 4 should have the samecalculations as contained in the 2006 Emission Inventory.Lime Kiln #2 (D275) limestoneLime Kiln #2 (D275) limestoneAssociatedStack IDRaw Material or FuelusedThroughpYear DAQ IDPt SourceID SCCDescription ofProcessNSPS(Yes/No)Lime Kiln #1 (D75) limestone42006 CalculationsLime Kiln #1 (D75) limestoneLime Kiln #1 (D75) limestoneThroughpYear DAQ IDPt SourceID SCCDescription ofProcessNSPS(Yes/No)AssociatedStack IDRaw Material or Fuelused32006 (if methodof calculation isdifferent from1998)1307 152/52 30501604 Yes 727632Amount1199811726 151c/51c 10301002 No 71 686022006 (using 1998method ofcalculation)11726(Now1306)151c/51c 10301002 No 711001232006 (if methodof calculation isdifferent from1998)11726(Now1306)151c/51c 10301002 No 7110012Amount1199811727 152c/52c 10301002 No 72 167522006 (using 1998method ofcalculation)11727(now1307)152c/52c 10301002 No 72938532006 (if methodof calculation isdifferent from1998)11727(now1307)152c/52c 10301002 No 72938542006 CalculationsFuel for K2Propane - GaseousFuel for K2Propane - GaseousFuel for K2Propane - GaseousAssociatedStack IDRaw Material or FuelusedThroughp42006 Calculations:Year DAQ IDPt SourceID SCCDescription ofProcessNSPS(Yes/No)Fuel for K1Propane - GaseousFuel for K1Propane - GaseousFuel for K1Propane - GaseousAssociatedStack IDRaw Material or FuelusedThroughp42006 CalculationsYear DAQ IDPt SourceID SCCDescription ofProcessNSPS(Yes/No)Lime Kiln #2 (D275) limestoneAmount1199811728 153c/53c 10301002 No 73 1163322006 (using 1998method ofcalculation)11728 153c/53c 10301002 No 73956132006 (if methodof calculation isdifferent from1998)11728 153c/53c 10301002 No 73956142006 CalculationsFuel for K3Propane - GaseousFuel for K3Propane - GaseousFuel for K3Propane - GaseousAssociatedStack IDRaw Material or FuelusedThroughpYear DAQ IDPt SourceID SCCDescription ofProcessNSPS(Yes/No)Amount119985188 2 30502009 No233.2522006 (using 1998method ofcalculation)5188 2 30502009 No50732006 (if methodof calculation isdifferent from1998)5188 2 30502009 No0Amount1199820138 54 30501604 Yes 17059 625522006 (using 1998method ofcalculation)20138 54 30501604 Yes 17059759032006 (if methodof calculation isdifferent from1998)20138 54 30501604 Yes 170597590Amount1199820141 54c 10301002 No 17059 8798Fuel for Kiln #4 Propane - GaseousAssociatedStack IDRaw Material or FuelusedThroughp42006 CalculationsYear DAQ IDPt SourceID SCCDescription ofProcessNSPS(Yes/No)Rotary Lime Kiln #4 LimeRotary Lime Kiln #4 LimeRotary Lime Kiln #4 LimeAssociatedStack IDRaw Material or FuelusedThroughp42006 CalculationsYear DAQ IDPt SourceID SCCDescription ofProcessNSPS(Yes/No)Blast ANFOlimestoneBlast ANFOlimestoneBlast ANFOlimestoneAssociatedStack IDRaw Material or FuelusedThroughpYear DAQ IDPt SourceID SCCDescription ofProcessNSPS(Yes/No)22006 (using 1998method ofcalculation)20141 54c 10301002 No 170591029232006 (if methodof calculation isdifferent from1998)20141 54c 10301002 No 1705910292Amount1199811730 (1308)53b30501604No73606622006 (using 1998method ofcalculation)11730 (1308)53b 30501604 No 73755632006 (if methodof calculation isdifferent from1998)11730 (1308)53b 30501604 Yes 737556EQUIPMENT NOT RUN IN 1998 THAT EMITS SOx2006 SOxHow sulfur content was calculated Tons/year3906 (now 1307) 52a0.28111729 (now 1308) 53a0.27220139 54a0.307172672 1030.064Fuel for Kiln #4Emissions were not calculated for 53b in 1998 (fuelfor Kiln #3). Emissions were calculated for 53, Lime Kiln #3 (D375), and were calculated using thesame method that was used to calculate emissions from Kiln #1, #2, and #4, which are based on the permit limit.Bituminous coal emissions are included as part of the emissions calculated for lime production for each kiln. Therefore, no explanation of the coal sulfurcontent is provided since the coal sulfur content is not used to calculate SO2 emissions from the kilns.Fuel for LGP DrierDAQ IDPointSource ID Description
