Following the EPA’s action, chlorine gas may continue to be used, provided that risk mitigation measures are followed by the applicators and certain data is submitted.

Chlorine products registered for use in public swimming pools, pulp and paper mill processes, and industrial food processing plants now must be applied and handled only by trained, certified applicators.

Chlorine products registered for drinking water, sewage, and waste water treatment uses, and residential pool uses will still be considered general use, but applicators will be required to follow more stringent labelling requirements to prevent exposure to people.
