This is not the same as a long list of endpoints for which testing would always be required.<\/li>\n<li>We also propose EPA have authority to \u201ctier\u201d testing requirements. This could be done to reflect the different exposure or hazard potentials described in the first bullet above. For some chemicals, it could also be used to initially apply screening tests, to be followed by more detailed tests should the screening tests raise red flags.<\/li>\n<li>We further propose that EPA could develop and tailor MDSs for categories of chemicals that have similar properties, hazards, use profiles or exposure potential.\u00a0<\/li>\n<li>Finally, EPA should also have authority to require MDSs for mixtures of chemicals as well as individual chemicals. In some cases, data on the mixture will be more useful in determining safety than data on the individual components.<\/li>\n<\/ul>\n<p><strong><em>WHEN chemical information should be provided<\/em><\/strong><\/p>\n<p>Because chemical information serves so many purposes (as I noted in <a rel=\"nofollow\"  href=\"http:\/\/blogs.edf.org\/nanotechnology\/2010\/04\/18\/a-minimum-data-set-who-needs-it\/\">my earlier post on this topic<\/a>), its development and submission should be expedited as much as possible. And because such information changes over time, it needs to be updated with sufficient frequency to ensure users have current and timely information.<\/p>\n<p>Of course, EPA will need some time to develop a rule that specifies the details of MDSs, the methods to be used to develop the data, etc. And a reasonable period of time then needs to be provided for companies to develop and submit the data. Finally, chemicals that are prioritized will be subject to safety determinations sooner, so their MDSs will be needed to be developed and submitted sooner than those for other chemicals.<\/p>\n<p>We propose, therefore:<\/p>\n<ul>\n<li>Companies should be required to submit information they already possess about a chemical\u2019s identity, properties, production, use, hazards and exposure potential within one year of enactment.<\/li>\n<li>Companies should update such information at a minimum every three years, and immediately whenever significant new information becomes available or significant changes in a chemical\u2019s production or use occur.<\/li>\n<li>EPA should develop and publish the MDS requirements within one year of enactment.<\/li>\n<li>MDSs for all <span style=\"text-decoration:underline;\">new<\/span> chemicals should be submitted at the time companies submit notices of intent to manufacture them. (A transition for new chemicals may be needed during the period between enactment of legislation and EPA\u2019s issuance of the details of the MDS).<\/li>\n<li>MDSs for all <span style=\"text-decoration:underline;\">existing<\/span> chemicals should be submitted within either:\n<ul>\n<li>five years of enactment, or<\/li>\n<li>for priority chemicals, 18 months after they are so identified,<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p> whichever comes first.<\/p>\n<ul>\n<li>If significant time has passed between initial submission of the MDS for a chemical and when it comes up for its safety determination, companies should have an opportunity and mandate to update their MDSs, so that the most current information is available to EPA.<\/li>\n<\/ul>\n<div class=\"feedflare\">\n<a href=\"http:\/\/feeds.feedburner.com\/~ff\/environmentaldefense?a=Bw5KWYv2Cbs:Vtlfp7d2Iuo:yIl2AUoC8zA\"><img decoding=\"async\" src=\"http:\/\/feeds.feedburner.com\/~ff\/environmentaldefense?d=yIl2AUoC8zA\" border=\"0\"><\/img><\/a> <a href=\"http:\/\/feeds.feedburner.com\/~ff\/environmentaldefense?a=Bw5KWYv2Cbs:Vtlfp7d2Iuo:2mJPEYqXBVI\"><img decoding=\"async\" src=\"http:\/\/feeds.feedburner.com\/~ff\/environmentaldefense?d=2mJPEYqXBVI\" border=\"0\"><\/img><\/a> <a href=\"http:\/\/feeds.feedburner.com\/~ff\/environmentaldefense?a=Bw5KWYv2Cbs:Vtlfp7d2Iuo:7Q72WNTAKBA\"><img decoding=\"async\" src=\"http:\/\/feeds.feedburner.com\/~ff\/environmentaldefense?d=7Q72WNTAKBA\" border=\"0\"><\/img><\/a> <a href=\"http:\/\/feeds.feedburner.com\/~ff\/environmentaldefense?a=Bw5KWYv2Cbs:Vtlfp7d2Iuo:u0Zhe-nyOHo\"><img decoding=\"async\" src=\"http:\/\/feeds.feedburner.com\/~ff\/environmentaldefense?d=u0Zhe-nyOHo\" border=\"0\"><\/img><\/a> <a href=\"http:\/\/feeds.feedburner.com\/~ff\/environmentaldefense?a=Bw5KWYv2Cbs:Vtlfp7d2Iuo:dnMXMwOfBR0\"><img decoding=\"async\" src=\"http:\/\/feeds.feedburner.com\/~ff\/environmentaldefense?d=dnMXMwOfBR0\" border=\"0\"><\/img><\/a>\n<\/div>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/feeds.feedburner.com\/~r\/environmentaldefense\/~4\/Bw5KWYv2Cbs\" height=\"1\" width=\"1\"\/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Richard Denison, Ph.D., is a Senior Scientist.
