For those of us that have been around awhile - there once was a thing called the TSCA Inventory, the Toxic Substance Control Act. Today, the inventory still exists but the historic TSCA Inventory Update reporting is now under "New Management" the CDR - the Chemical Data Reporting. CDR reporting began in 2006 and included more than just manufacturing quantities. Today's CDR includes chemical use information as well as screening-level, and exposure-level information and to make that information Public. (Note: the public information is contained in the non-confidential data. There is still a significant amount of data in the confidential reporting. However, due to changes in the regulations, the amount of data that can still be excluded as confidential is dwindling.)
This reporting is slated for every four years - with the last reporting for the 2012 submission period. The next reporting period will be from June 1, 2016 to September 30, 2016. However, on June 11, 2014 - EPA released the the publicly available non-confidential 2012 CDR database and three fact sheets. (Recall that there is a confidential database as well. The non-confidential and confidential databases causes the manufacturers of chemicals a bit of problem because it creates a two step process in determining whether or not your chemical is on the TSCA list.)
It should be pointed out that some of the changes to the 2012 reporting were made based on the amount of time it took to make available the information from the 2006 reporting to the public.
You can get all the information on the 2012 Reporting Period on the EPA CDR Website. But, ere are some interesting facts:
* 434 more Total Form U's were reported even though there was a net decline of 51 companies reporting. The change related to the number of sites reporting and probably reflects the various consolidations that have occurred. (Note as well there were several changes in definitions that should have resulted in more reporting.)
* There was an increase of 610 chemicals being reported.
* The number of imported chemicals reported increased from 2,886 to 3,568. Which included an increase from 215 to 355 of for chemicals used in children's products.
* There was an increase of 724 chemicals with reported consumer/commercial use information and significant increases in downstream and industrial process and use information.
So, it appears just from the raw data - EPA was able to get the additional information it was seeking. Yet, it remains to be seen if this information meets the needs of the users of the data. The release of the 2012 information is the first step in this determination.
EPA, also, released a Fact Sheet - "Second CDR Snapshot" which includes listings of the top chemicals reported by use and production volume.
The top five chemicals based on production volume are: 1) Carbon Dioxide, 2) Ethanol, 3) Sulfuric Acid, 4) Tricalcium silicate and 5) Ethene.
The top five industrial sectors that process and use CDR chemicals are 1) paper manufacturing (34.49%), 2) mining (except oil and gas)(29.25%), 3) primary metal manufacturing (7.75%), 4) all other basic organic chemical manufacturing (4.05%) and 5) non-metallic mineral product manufacturing (3.25%) which includes clay, glass, cement, concrete, lime, gypsum and other non-metallic mineral product manufacturing. Petrochemical manufacturing (2.41%) and petroleum refining (2.28%) only account for 4.69 % combined.
It will be interesting to see how this information is going to be used and disseminated prior to the next reporting period.
