Tetrachloroethylene (Use in Dry Cleaning and Reporting Requirements) Regulations

8 (1) The owner or operator of a dry-cleaning machine shall have all waste water

• (a) transported to a waste management facility no less than once every 12 months; or

• (b) treated by the dry-cleaning machine’s or the carbon adsorber’s integral tetrachloroethylene-water separator and an on-site waste water treatment system that contains the following equipment:

  • (i) a second tetrachloroethylene-water separator that recovers tetrachloroethylene from the waste water exiting the integral tetrachloroethylene-water separator,

  • (ii) an initial filter containing activated carbon that removes the tetrachloroethylene from the waste water exiting the second tetrachloroethylene-water separator,

  • (iii) a monitor-alarm that automatically shuts down the waste water treatment system when the initial filter becomes saturated with tetrachloroethylene, and

  • (iv) a second filter containing activated carbon that removes tetrachloroethylene from the waste water after it passes through the initial filter and past the monitor-alarm.

(2) When having waste water transported pursuant to paragraph (1)(a), the owner or operator shall have transported all of the waste water that is within the dry-cleaning facility at the time of the transport that has not been treated by the waste water treatment system described in paragraph (1)(b).
