| 5. Each lime kiln and each associated lime cooler, if there is a separate exhaust to the atmosphere from the associated lime cooler, and which uses a negative pressure PM control device | Measure PM emissions | Method 5 in appendix A to part 60 of this chapter | Conduct the test(s) when the source is operating at representative operating conditions in accordance with §63.7(e); the minimum sampling volume must be 0.85 dry standard cubic meter (dscm) (30 dry standard cubic foot (dscf)); if there is a separate lime cooler exhaust to the atmosphere, you must conduct the Method 5 test of the cooler exhaust concurrently with the kiln exhaust test. |
| 6. Each lime kiln and each associated lime cooler, if there is a separate exhaust to the atmosphere from the associated lime cooler, and which uses a positive pressure FF or ESP | Measure PM emissions | Method 5D in appendix A to part 60 of this chapter | Conduct the test(s) when the source is operating at representative operating conditions in accordance with §63.7(e); if there is a separate lime cooler exhaust to the atmosphere, you must conduct the Method 5 test of the separate cooler exhaust concurrently with the kiln exhaust test. |
| 7. Each lime kiln | Determine the mass rate of stone feed to the kiln during the kiln PM emissions test | Any suitable device | Calibrate and maintain the device according to manufacturer's instructions; the measuring device used must be accurate to within ±5 percent of the mass rate of stone feed over its operating range. |
| 8. Each lime kiln equipped with a wet scrubber | Establish the operating limit for the average gas stream pressure drop across the wet scrubber | Data for the gas stream pressure drop measurement device during the kiln PM performance test | The continuous pressure drop measurement device must be accurate within plus or minus 1 percent; you must collect the pressure drop data during the period of the performance test and determine the operating limit according to §63.7112(j). |
| 9. Each lime kiln equipped with a wet scrubber | Establish the operating limit for the average liquid flow rate to the scrubber | Data from the liquid flow rate measurement device during the kiln PM performance test | The continuous scrubbing liquid flow rate measuring device must be accurate within plus or minus 1 percent; you must collect the flow rate data during the period of the performance test and determine the operating limit according to §63.7112(j). |
| 10. Each lime kiln equipped with a FF or ESP that is monitored with a PM detector | Have installed and have operating the BLDS or PM detector prior to the performance test | Standard operating procedures incorporated into the OM&M plan | According to the requirements in §63.7113(d) or (e), respectively. |
| 11. Each lime kiln equipped with a FF or ESP that is monitored with a COMS | Have installed and have operating the COMS prior to the performance test | Standard operating procedures incorporated into the OM&M plan and as required by 40 CFR part 63, subpart A, General Provisions and according to PS-1 of appendix B to part 60 of this chapter, except as specified in §63.7113(g)(2) | According to the requirements in §63.7113(g). |
| 12. Each stack emission from a PSH operation, vent from a building enclosing a PSH operation, or set of multiple storage bins with combined stack emissions, which is subject to a PM emission limit | Measure PM emissions | Method 5 or Method 17 in appendix A to part 60 of this chapter | The sample volume must be at least 1.70 dscm (60 dscf); for Method 5, if the gas stream being sampled is at ambient temperature, the sampling probe and filter may be operated without heaters; and if the gas stream is above ambient temperature, the sampling probe and filter may be operated at a temperature high enough, but no higher than 121 °C (250 °F), to prevent water condensation on the filter (Method 17 may be used only with exhaust gas temperatures of not more than 250 °F). |
| 13. Each stack emission from a PSH operation, vent from a building enclosing a PSH operation, or set of multiple storage bins with combined stack emissions, which is subject to an opacity limit | Conduct opacity observations | Method 9 in appendix A to part 60 of this chapter | The test duration must be for at least 3 hours and you must obtain at least thirty, 6-minute averages. |
| 14. Each stack emissions source from a PSH operation subject to a PM or opacity limit, which uses a wet scrubber | Establish the average gas stream pressure drop across the wet scrubber | Data for the gas stream pressure drop measurement device during the PSH operation stack PM performance test | The pressure drop measurement device must be accurate within plus or minus 1 percent; you must collect the pressure drop data during the period of the performance test and determine the operating limit according to §63.7112(j). |
| 15. Each stack emissions source from a PSH operation subject to a PM or opacity limit, which uses a wet scrubber | Establish the operating limit for the average liquid flow rate to the scrubber | Data from the liquid flow rate measurement device during the PSH operation stack PM performance test | The continuous scrubbing liquid flow rate measuring device must be accurate within plus or minus 1 percent; you must collect the flow rate data during the period of the performance test and determine the operating limit according to §63.7112(j). |
| 16. Each FF that controls emissions from only an individual, enclosed, new or existing storage bin | Conduct opacity observations | Method 9 in appendix A to part 60 of this chapter | The test duration must be for at least 1 hour and you must obtain ten 6-minute averages. |
| 17. Fugitive emissions from any PSH operation subject to an opacity limit | Conduct opacity observations | Method 9 in appendix A to part 60 of this chapter | The test duration must be for at least 3 hours, but the 3-hour test may be reduced to 1 hour if, during the first 1-hour period, there are no individual readings greater than 10 percent opacity and there are no more than three readings of 10 percent during the first 1-hour period. |
| 18. Each building enclosing any PSH operation, that is subject to a VE limit | Conduct VE check | The specifications in §63.7112(k) | The performance test must be conducted while all affected PSH operations within the building are operating; the performance test for each affected building must be at least 75 minutes, with each side of the building and roof being observed for at least 15 minutes. |
