| 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) before the relevant compliance date for your source as specified in §63.7083(e) and §63.7112(b) on and after the relevant compliance date for your source as specified in §63.7083(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) before the relevant compliance date for your source as specified in §63.7083(e) and §63.7112(b) on and after the relevant compliance date for your source as specified in §63.7083(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. |
