EPA simply must do better on transparency and chemical data access

Under this Administration, EPA has taken some significant steps toward reversing decades of passivity and secretive practices that evolved under the Toxic Substances Control Act (TSCA) when it came to transparency in decision-making and providing access to chemical information it obtains or develops.

Several initiatives undertaken through what EPA originally termed its enhanced chemicals management program have developed and laid out clearer policies and procedures in areas such as:  chemical prioritization (leading to its Work Plan Chemicals Program); enforcing limits on and reviewing confidential business information (CBI) claims asserted by industry (leading to its declassification of hundreds of previously hidden chemical identities and health and safety studies that companies had illegitimately claimed confidential or no longer merited protection from disclosure, but that EPA had not bothered to review or challenge before now); and EPA’s regulatory efforts to reduce risks from exposures to toxic chemicals (leading to its Action Plans on high-concern chemicals and proposed follow-up activities for work plan chemicals where assessments – the first completed in decades – have identified significant risks).

EPA has also developed new databases and tools to provide greater access to chemical information in its possession and regulatory decisions and supporting documents it develops; these include the Chemical Data Access Tool and ChemView.

All of these efforts are still very much works in progress but hold significant potential to improve transparency, information access and risk reduction.

But sometimes the Agency does something that makes clear just how far it still has to go in these respects.  Unfortunately, a case in point is its recent effort toward assessing risks of a cluster of flame retardant chemicals, the brominated phthalates, some of which are in wide use and are showing up in everything from house dust to dolphins.   Read More »

Very little, very late: EPA still lacks data on safety of widely used flame retardant chemicals

Last summer, EPA released a Problem Formulation and Data Needs Assessment describing the inadequacy of data available to conduct risk assessments on a group of brominated phthalate flame retardants – two of which are major components in widely used Firemaster products. 

This is the first of two blog posts on the comments EDF recently submitted to EPA on this document.  In this post, we discuss the growing public health and environmental concerns over use of Firemaster products and the recommendations we made to EPA on steps it needs to promptly take to address these concerns.  In our second post, we’ll lay out our serious concerns about the lack of transparency, limited data access, and allowance of unwarranted confidentiality claims that our review of EPA’s document brought to light.

 

First, a brief history

In the mid-2000s, Great Lakes Chemicals Corporation (now Chemtura) agreed to phase out production of polybrominated diphenyl ether (PBDE) flame retardants due to mounting evidence of their health effects and their persistence and accumulation in people and the environment.  Soon after, the use of the company’s replacement Firemaster products skyrocketed.

The two main components of Firemaster products, 2-Ethylhexyl 2,3,4,5- tetrabromobenzoate (TBB) and bis(2-Ethylhexyl) -3,4,5,6- tetrabromophthalate (TBPH), are  high production volume (“HPV”) chemicals – each produced at more than one million pounds annually.

Unfortunately, use of these chemicals rose to such levels – replacing PBDEs in consumer products like polyurethane foam-based furniture and electronics – without sufficient data and review to establish their safety.   Read More »
