Canada periodically puts out mandatory survey on batches of chemicals as it works through its prioritization process. For example in June there were 8 MDA/MDI chemicals of interest.  It’s a pretty comprehensive set of information demanded of manufacturers, importers and processors: volumes, uses available toxicity information and a list of the top 20 customers.  With the possible exception of getting customer lists, such information can be obtained under TSCA section 8 - basically CDR + 8(d) - applied to manufacturers, importers and processors.  

But note that Canada is only going after EIGHT chemicals in this notice - not thousands at a time like EPA does under CDR!  As Canada identifies categories of chemicals they are concerned about, they hold webinars and issue "mandatory surveys" - evaluate the information and go back for more if they need it (link).  Granted, they have far fewer companies and chemicals to cope with than the US, but note how they are being systematic about working through their inventory on a priority basis.

Maybe advocates for TSCA Reform are right - EPA needs the kick in the pants of legislative instructions to actually do something under TSCA.  The trouble is pick-a-number is pretty arbitrary.  But maybe that's where we are at?  The Agency has had numerous initiatives - like ChAMP, HPV, Chemical Action Plans and now a "Work Plan" - but they always seem to run out of gas.  I still hold there is a ton of authority in the current TSCA for EPA to take action - especially if they tackle chemicals by category (section 26) and not try to do humungous every-test-known-to-man and/or ban-it-all regulations.

I'd certainly recommend looking to Canada as opposed to Europe as a model to emulate.
