Reporting a treatment method used on a waste stream that does not destroy, chemically convert, or physically remove the chemical

Section 7A of the TRI Form R requires facilities to report on-site waste treatment methods and their efficiency.  Does a facility have to report a treatment method used on a waste stream containing a TRI chemical if the treatment does not destroy, chemically convert, or physically remove the chemical within the waste stream?

Most of the information reported on the Form R is specific to the TRI chemical, rather than the waste stream containing that chemical.  However, facilities must report waste treatment methods applied on site to waste streams that contain the TRI chemical, even if the waste treatment method does not remove the specific TRI chemical being reported.  In the event that a facility is reporting a waste treatment that does not destroy, chemically convert, or physically remove the TRI chemical, the efficiency is zero and the facility must report efficiency code E6 (equal to or greater than 0%, but less than or equal to 50%) for that treatment method.
