Emissions Averaging Emission Limits

As required in § 63.7090(d), if you are using emissions averaging for either HCl emission limits or mercury emission limits you must meet each emission limit in the following table that applies to you. For . . . You must meet the following emission limit 1. Existing straight rotary lime kilns and their associated coolers producing dolomitic quick lime and/or dead burned dolomitic lime HCl emissions must not exceed 2.1 lb/ton of lime produced. 2. Existing straight rotary lime kilns and their associated coolers producing high-calcium quick lime HCl emissions must not exceed 0.047 lb/ton of lime produced. 3. Existing preheater rotary lime kilns and their associated coolers producing dolomitic quick lime and/or dead burned dolomitic lime HCl emissions must not exceed 0.36 lb/ton of lime produced. 4. Existing preheater rotary lime kilns and their associated coolers producing high-calcium quick lime HCl emissions must not exceed 0.087 lb/ton of lime produced. 5. All vertical lime kilns and their associated coolers producing dolomitic quick lime and/or dead burned dolomitic lime HCl emissions must not exceed 0.36 lb/ton of lime produced. 6. All vertical lime kilns and their associated coolers producing high-calcium quick lime HCl emissions must not exceed 0.019 lb/ton of lime produced. 7. Existing lime kilns and their associated coolers Mercury emissions must not exceed 31 lb/MMton of lime produced. [89 FR 57757, July 16, 2024]
