Appendix - Table 1 to Subpart AAAAA of Part 63—Emission Limits

As required in § 63.7090(a), you must meet each emission limit in the following table that applies to you, except for kilns and coolers during startup and shutdown (see table 2 to this subpart for emission limits for kilns and coolers during startup and shutdown).

For . . . You must meet the following emission limit
1. All existing lime kilns and their associated lime coolers that did not have a wet scrubber installed and operating prior to January 5, 2004PM emissions must not exceed 0.12 pounds per ton of stone feed (lb/tsf).
2. All existing lime kilns and their associated lime coolers that have a wet scrubber, where the scrubber itself was installed and operating prior to January 5, 2004PM emissions must not exceed 0.60 lb/tsf. If, at any time after January 5, 2004, the kiln changes to a dry control system, then the PM emission limit in item 1 of this table 1 applies, and the kiln is hereafter ineligible for the PM emission limit in item 2 of this table 1 regardless of the method of PM control.
3. All new lime kilns and their associated lime coolersPM emissions must not exceed 0.10 lb/tsf.
4. All existing and new lime kilns and their associated coolers at your LMP, and you choose to average PM emissions, except that any kiln that is allowed to meet the 0.60 lb/tsf PM emission limit is ineligible for averagingWeighted average PM emissions calculated according to equation 2 to § 63.7112(f)(1) must not exceed 0.12 lb/tsf (if you are averaging only existing kilns) or 0.10 lb/tsf (if you are averaging only new kilns). If you are averaging existing and new kilns, your weighted average PM emissions must not exceed the weighted average emission limit calculated according to equation 3 to § 63.7112(g), except that no new kiln and its associated cooler considered alone may exceed an average PM emissions limit of 0.10 lb/tsf.
5. New straight rotary lime kilns and their associated coolers producing dolomitic quick lime and/or dead burned dolomitic limeHCl emissions must not exceed 1.7 lb/ton of lime produced.
6. Existing straight rotary lime kilns and their associated coolers producing dolomitic quick lime and/or dead burned dolomitic limeHCl emissions must not exceed 2.3 lb/ton of lime produced.
7. New straight rotary lime kilns and their associated coolers producing high-calcium quick limeHCl emissions must not exceed 0.015 lb/ton of lime produced.
8. Existing straight rotary lime kilns and their associated coolers producing high-calcium quick limeHCl emissions must not exceed 0.52 lb/ton of lime produced.
9. All preheater rotary lime kilns and their associated coolers producing dolomitic quick lime and/or dead burned dolomitic limeHCl emissions must not exceed 0.39 lb/ton of lime produced.
10. All preheater rotary lime kilns and their associated coolers producing high-calcium quick limeHCl emissions must not exceed 0.096 lb/ton of lime produced.
11. All vertical lime kilns and their associated coolers producing dolomitic quick lime and/or dead burned dolomitic limeHCl emissions must not exceed 0.39 lb/ton of lime produced.
12. All vertical lime kilns and their associated coolers producing high-calcium quick limeHCl emissions must not exceed 0.021 lb/ton of lime produced.
13. All new lime kilns and their associated coolersMercury emissions must not exceed 27 lb/MMton of lime produced.
14. All existing lime kilns and their associated coolersMercury emissions must not exceed 34 lb/MMton of lime produced.
15. All lime kilns and their associated coolersTotal Organic HAP emissions must not exceed 2.6 ppmvd @7% O2.
16. All lime kilns and their associated coolersD/F emissions must not exceed 0.037 ng/dscm (TEQ) 1 @7% O2.
17. Stack emissions from all PSH operations at a new or existing affected sourcePM emissions must not exceed 0.05 grams per dry standard cubic meter (g/dscm).
18. Stack emissions from all PSH operations at a new or existing affected source, unless the stack emissions are discharged through a wet scrubber control deviceEmissions must not exceed 7 percent opacity.
19. Fugitive emissions from all PSH operations at a new or existing affected source, except as provided by item 8 of this table 1Emissions must not exceed 10 percent opacity.
20. All PSH operations at a new or existing affected source enclosed in a buildingAll of the individually affected PSH operations must comply with the applicable PM and opacity emission limitations in items 5 through 7 of this table 1, or the building must comply with the following: There must be no VE from the building, except from a vent; and vent emissions must not exceed the stack emissions limitations in items 5 and 6 of this table 1.
21. Each FF that controls emissions from only an individual, enclosed storage binEmissions must not exceed 7 percent opacity.
22. Each set of multiple storage bins at a new or existing affected source, with combined stack emissionsYou must comply with the emission limits in items 5 and 6 of this table 1.

When calculating TEQ, zero may be used for congeners that are below the estimated detection level (EDL).
