EPA proposes banning all consumer and most industrial uses of dichloromethane

Via (among other places) the DCHAS-L listserve, this EPA press release: 
...EPA’s proposed risk management rule would rapidly phase down manufacturing, processing and distribution of methylene chloride for all consumer uses and most industrial and commercial uses, most of which would be fully implemented in 15 months. For most of the uses of methylene chloride that EPA is proposing to prohibit, EPA’s analysis found that alternative products with similar costs and efficacy to methylene chloride products are generally available.

...For the industrial manufacturing, industrial processing, and federal uses that EPA is not proposing to prohibit, EPA is proposing a workplace chemical protection program with strict exposure limits to better protect workers. EPA has received data from industry that indicate some facilities may already be meeting the stronger proposed methylene chloride exposure limits. These proposed requirements would allow the continued processing of methylene chloride to produce chemicals that are important in efforts to reduce global warming outlined in the American Innovation and Manufacturing Act. Climate-friendly refrigerants and other chemicals play a significant role in combatting climate change and EPA’s proposed rule supports continued efforts to reduce emissions. 
For those interested, here is the main page, and here is the proposed rule. 

What I've gathered so far (which could be incorrect): 
  • The proposed timeline for implementation is around 15 months. 
  • This would affect academic laboratories (laboratory use is one of the ten restricted uses that requires a workplace chemical protection program) 
  • This would affect industrial laboratories, as well 
  • Industrial use in the pharmaceutical industry may not be impacted, as pharmaceutical use is exempted from TSCA (page 14 of the proposed rule) 
I'm not an environmental lawyer, so I have no idea how real this is, but it seems like something that is pretty real? Readers?
