This source states these in separate places, so each value is shown with the passage that states it.
Action level
(2) Action levels. (i) The action level for yarn manufacturing and cotton washing operations is an airborne concentration of lint-free respirable cotton dust of 100 µg/m 3 mean concentration, averaged over an eight-hour period, as measured by a vertical elutriator or an equivalent instrument.
PEL
Yarn manufacturing means all textile mill operations from opening to, but not including, slashing and weaving. (c) Permissible exposure limits and action levels —(1) Permissible exposure limits (PEL). (i) The employer shall assure that no employee who is exposed to cotton dust in yarn manufacturing and cotton washing operations is exposed to airborne concentrations of lint-free respirable cotton dust greater than 200 µg/m 3 mean concentration, averaged over an eight-hour period, as measured be a vertical elutriator or an equivalent instrument .
Surveillance trigger
Where infeasible, the method used for handling cotton and cotton waste shall be the method which reduces exposure to the lowest level feasible. (h) Medical surveillance—(1) General.
