EPA deserves an “A for Effort” for its new Chemical Action Plans

Just squeaking in under its self-imposed deadline, late on December 30 EPA issued the first batch of chemical action plans it has promised under its enhanced chemical management program.  In doing so, EPA has signaled its intention to do all it can using its existing authority under the Toxic Substances Control Act (TSCA) – even as it also makes clear that authority is “both outdated and in need of reform.”  To my ear, that strikes just the right balance.

How to turn a “quick start” into a choke point

By / Published: November 18, 2009

Richard Denison, Ph.D., is a Senior Scientist.

Over the last few months, I was heartened to hear a number of industry stakeholders in the debate over TSCA reform embrace the idea of designating in TSCA reform legislation a “jump-start” or “quick-start” list of chemicals of high concern or priority.  The idea was to allow EPA to hit the ground running, by having an agreed-to list of chemicals on which it could immediately initiate action.  Well, it now appears many in industry actually have something far slower and far more cumbersome in mind.

Over-Exposed: Why relying on exposure to prioritize chemicals is dangerous

By / Published: November 11, 2009

Richard Denison, Ph.D., is a Senior Scientist.

When the chemical industry talks about prioritization – a central question in the debate over TSCA reform – more often than not it quickly reduces the question down to the argument that we should focus only on those chemicals, however hazardous or untested they may be, to which we know people are exposed.  In a perfect world, that might suffice.  But, as this post will explore, the world of exposure assessment is anything but perfect.  Read More »

Let the games begin: Dueling TSCA reform manifestos

By / Published: August 4, 2009

Richard Denison, Ph.D., is a Senior Scientist.

Today, the American Chemistry Council (ACC) unveiled its “10 Principles for Modernizing TSCA.”  Also today, the Safer Chemicals, Healthy Families coalition – of which EDF is a member – issued a news release and unveiled its 9-point “Platform for Reform of TSCA.”  How do they line up? Read More »

O Canada!

By / Published: July 24, 2009

Richard Denison, Ph.D., is a Senior Scientist.

Some time back, I promised a look at whether Canada’s Chemical Management Plan provides a model for TSCA reform.  This post will provide that look.  Bottom line:  While our neighbor to the north has undertaken and accomplished a great deal over the past decade, it has done so with one hand tied behind its back.  Read More »

ChAMP’s double standard

By / Published: June 1, 2009

Richard Denison, Ph.D., is a Senior Scientist.

This new post serves as a response to Charlie Auer’s most recent comment responding to our critique of ChAMP.  (To see the whole exchange, start here, then go here, here and here.)  So far, this exchange has focused mainly on our disagreement over whether or not EPA is somehow required to do risk assessments under ChAMP.  At some point, I hope Charlie and others will engage on the substance of our critique – the serious concerns we’ve raised about the quality and validity of the ChAMP assessments.
