| (2) Hardwood veneer dryer | Process less than 30 volume percent softwood species | Maintaining the volume percent softwood species processed below 30 percent AND keeping records of the volume percent softwood species processed.
|
| (3) Softwood veneer dryer | Minimize fugitive emissions from the dryer doors and the green end | Following (and documenting that you are following) your plan for minimizing fugitive emissions.
|
| (4) Veneer redryers | Process veneer with an inlet moisture content of less than or equal to 25 percent (by weight, dry basis) | Maintaining the 24-hour block average inlet moisture content of the veneer processed at or below of less than or 25 percent AND keeping records of the inlet moisture content of the veneer processed.
|
| (5) Group 1 miscellaneous coating operations | Use non-HAP coatings as defined in § 63.2292 | Continuing to use non-HAP coatings AND keeping records showing that you are using non-HAP coatings.
|
| (6) Process units and control systems undergoing safety-related shutdown on and after August 13, 2021, except as noted in footnote “1” to this table | Follow documented site-specific procedures to ensure the flow of raw materials and fuel or process heat ceases and that material is removed from the process unit(s) as expeditiously as possible given the system design to reduce air emissions | Keeping records showing that you are following the work practice requirements during safety-related shutdowns.
|
| (7) Pressurized refiners undergoing startup or shutdown on and after August 13, 2021, except as noted in footnote “1” to this table | Route exhaust gases from the pressurized refiner to its dryer control system no later than 15 minutes after wood is fed to the pressurized refiner during startup. Stop wood flow into the pressurized refiner no more than 15 minutes after wood fiber and exhaust gases from the pressurized refiner stop being routed to the dryer during shutdown. | Keeping records showing that you are following the work practice requirements during pressurized refiner startup and shutdown events.
|
| (8) Direct-fired softwood veneer dryers undergoing startup or shutdown of gas-fired burners on and after August 13, 2021, except as noted in footnote “1” to this table | Cease feeding green veneer into the softwood veneer dryer and minimize the amount of time direct gas-fired softwood veneer dryers are vented to the atmosphere due to the conditions described in § 63.2250(d) | Keeping records showing that you are following the work practice requirements while undergoing startup or shutdown of softwood veneer dryer direct gas-fired burners.
