Question # 357

357. Are the listed toxic chemicals contained in process-related equipment, such as piping, eligible for the structural component exemption?
No. If pipes are process-related, the structural component exemption does not apply and the facility may have to consider toward the facility’s threshold determination, amounts of listed toxic chemicals contained in process-related pipes that are put into use during the reporting year. And the facility would have to include release and other waste management amounts in calculations where applicable.
