iii. comply with the work practice standard for closed-vent systems.
   c. each existing rayon operationi. reduce total uncontrolled sulfide emissions (reported as carbon disulfide) by at least 35% within 3 years after the effective date based on a 6-month rolling average; for each vent stream that you control using a control device, route the vent stream through a closed-vent system to the control device; and comply with the work practice standard for closed-vent systems; and
ii. reduce total uncontrolled sulfide emissions (reported as carbon disulfide) by at least 40% within 8 years after the effective date based on a 6-month rolling average; for each vent stream that you control using a control device, route the vent stream through a closed-vent system to the control device; and comply with the work practice standard for closed-vent systems.
   d. each new rayon operationi. reduce total uncontrolled sulfide emissions (reported as carbon disulfide) by at least 75% based on a 6-month rolling average;
ii. for each vent stream that you control using a control device, route the vent stream through a closed-vent system to the control device; and
iii. comply with the work practice standard for closed-vent systems.
   e. each existing or new cellulosic sponge operationi. reduce total uncontrolled sulfide emissions (reported as carbon disulfide) by at least 75% based on a 6-month rolling average;
ii. for each vent stream that you control using a control device, route the vent stream through a closed-vent system to the control device; and
iii. comply with the work practice standard for closed-vent systems.
   f. each existing or new cellophane operationi. reduce total uncontrolled sulfide emissions (reported as carbon disulfide) by at least 75% based on a 6-month rolling average;
ii. for each vent stream that you control using a control device (except for retractable hoods over sulfuric acid baths at a cellophane operation), route the vent stream through a closed-vent system to the control device; and
iii. comply with the work practice standard for closed-vent systems (except for retractable hoods over sulfuric acid baths at a cellophane operation).
2. the sum of all solvent coating process ventsa. each existing or new cellophane operationi. reduce uncontrolled toluene emissions by at least 95% based on a 6-month rolling average;
ii. for each vent stream that you control using a control device, route the vent stream through a closed-vent system to the control device; and
iii. comply with the work practice standard for closed-vent systems.
3. the sum of all cellulose ether process ventsa. each existing or new cellulose ether operationi. reduce total uncontrolled organic HAP emissions by at least 99%;
ii. for each vent stream that you control using a control device, route the vent stream through a closed-vent system to the control device; and
iii. comply with the work practice standard for closed-vent systems.
4. closed-loop systemseach existing or new cellulose ether operationcomply by operating the closed-loop system.
5. each carbon disulfide unloading and storage operationa. each existing or new viscose process affected sourcei. reduce uncontrolled carbon disulfide emissions by at least 83% from unloading and storage operations based on a 6-month rolling average if you use an alternative control technique not listed in this table source for carbon disulfide unloading and storage operations; if using a control device to reduce emissions, route emissions through a closed-vent system to the control device; and comply with the work practice standard for closed-vent systems;
ii. reduce uncontrolled carbon disulfide emissions by at least 0.14% from viscose process vents based on a 6-month rolling average; for each vent stream that you control using a control device, route the vent stream through a closed-vent system to the control device; and comply with the work practice standard for closed-vent systems;
