More chemicals added to EPA watch list

EPA adds 23 chemicals, including BPA, to key list for scrutiny, possible action

Assessing health risks for chemicals
is hard, ongoing work.

The Environmental Protection Agency has added 23 chemicals — including bisphenol A (BPA), seven phthalates and two flame retardants — to a key list of chemicals that will have particular uses carefully scrutinized for possible regulation or other controls.

The agency on Oct. 23 updated the list of chemicals in commerce that meet certain criteria, such as being used in children's products or being carcinogenic, persistent in the environment or harmful to development, reproduction or the neurological system.

Manufacturers of some of the newly added chemicals include Dow Chemical Co., DuPont, Eastman Chemical Co., Mexichem S.A.B de C.V., Momentive Performance Materials Holdings LLC and Webb Chemical Service Corp.

The EPA also removed 15 chemicals and groups of chemicals from the Toxic Substances Control Act Work Plan list.

The updated TSCA Work Plan now lists 90 chemicals and chemical groups.

The agency is assessing the risks of particular uses of chemicals on that list. It already has completed four assessments and has initiated risk management actions for trichloroethylene (TCE) and methylene chloride.

Assessments for the newly added chemicals will begin after 2017, the agency said.

Depending on the findings of its risk assessments, the agency could decide to regulate one or more uses of the chemical, work with industry to reduce exposures or conclude that its analysis showed a particular use raised no concerns.

Richard Denison, lead senior scientist with the Environmental Defense Fund, commended the EPA for updating its work plan to reflect new data.

“The work plan should be a living document that is revised as new information emerges,” he said.

Scientist questions removal of chemicals

Denison questioned the agency's decision to remove 13 chemicals because manufacturers didn't report making them in 2011, the most recent year for which the agency obtained production volume information. The agency said it concluded that these 13 chemicals were no longer in commerce.

“Reporting under the Chemical Data Reporting rule is subject to a high threshold of 25,000 pounds per site in the reporting year. In addition, numerous exemptions from reporting are provided,” Denison said.

Given the threshold and exemptions, the EPA should explain how it determined the chemicals are no longer being produced in or imported into the U.S. at any level by any company, Denison said.

The EPA's selection of some of the 23 newly added chemicals isn't surprising, as the agency voiced concerns about possible health or environmental harms they could cause in action plans it released between December 2009 and April 2011.

Those chemicals and chemical groups are decabromodiphenyl ether (decaBDE), hexabromocyclododecane (HBCD), nonylphenol and nonylphenol ethoxylates and the seven phthalates.

The EPA added the remaining chemicals for reasons such as 2011 Toxics Release Inventory data showing elevated releases into the environment; 2012 Chemical Data Reporting (CDR) rule information showing the chemicals are used in consumer products, including children's products; and the compounds being newly identified as presenting significant health or environmental hazards.

Other newly added chemicals

The 12 chemicals the agency added for such reasons are:

• 1,3-butadiene, Chemical Abstracts Service (CAS) No. 106-99-0, a commodity petrochemical that the EPA said increasingly is used to make rocket fuels, plastics, commercial latex paints and other compounds. Manufacturers, including Chevron Phillips Chemical Co., Lanxess Corp. and Michelin Corp., reported making or importing more than 4.3 billion pounds in 2011.

• 2,5-furandione, CAS No. 108-31-6, a chemical intermediate that the EPA said is used to make thousands of adhesives, floor polishes, leather treatments, personal care products, water treatment chemicals and other compounds. Manufacturers, including Goodyear Tire & Rubber Co., Greenchem Industries LLC and Lanxess, reported making or importing more than 572 million pounds in 2011.

• dimethylaminoethanol, CAS No. 108-01-0, which the EPA said is used to make dyestuffs, pharmaceuticals, corrosion inhibitors and other compounds. Manufacturers, including BASF Corp., Huntsman Corp. and Solvchem Inc., reported making or importing more than 120 million pounds in 2011.

• 2-hydroxy-4-(octyloxy)benzophenone, CAS No. 1843-05-6, which the EPA said is used in rubber and plastic products as well as food packaging. Manufacturers, including BASF Corp., Cytec Industries Inc. and SC Johnson & Son Inc., reported making or importing 2 million pounds in 2011.

•  3,3'-dichlorobenzidine, CAS No. 91-94-1, which the EPA said is a probable human carcinogen used to make dyes. No public manufacturing or production volume data were available from the agency's CDR rule website.

• 4,4'-(1-methylethylidene)bis[2,6-dibromophenol], or TBBPA, CAS No. 79-94-7, which the EPA said is used to inhibit combustion in epoxy resin circuit boards and electronic enclosures. Manufacturers, including Albemarle Corp., LG International America Inc. and Sabic Innovative Plastics US LLC, reported making or importing 120 million pounds in 2011.

• barium carbonate, CAS No. 513-77-9, which the EPA said is used in oil well drilling and used to make products including paper, special glass, ceramics, bricks and electrodes. Manufacturers, including Chemical Products Corp., Ferro Corp. and Solvay America Inc., reported making or importing 36 million pounds in 2011.

• dicyclohexyl phthalate, CAS No. 84-61-7, which the EPA said is used to make plastics and as a heat sealer for paper finishes such as price labels and pharmaceutical labels. Wind Point Partners, Lanxess and a company that withheld its name (saying it was confidential business information) reported making or importing between 500,000 and 1 million pounds in 2011.

• isopropylated phenol, phosphate or iPTPP, CAS No. 68937-41-7, which the EPA said is used as a flame retardant. Manufacturers, including Chevron Corp., ICL-Industrial Products America Inc. and Special Material Co., reported making or importing 15 million pounds in 2011.

• molybdenum and molybdenum compounds, a category of chemical used as alloying agents in cast iron, steel and other metals. Because this is a group of chemicals, Bloomberg BNA could not obtain national production data.

• pentachlorothio-phenol, CAS No. 133-49-3, which the EPA said is used to make rubber more pliable. The EPA withheld production volume data for this chemical to protect the proprietary business information of Strucktol Co. of America, the sole manufacturer, which reported making or importing it in 2011.

• triphenyl phosphate or TPP, CAS No. 115-86-6, which the EPA said is widely used to slow fires in polyurethane foam, polyvinyl chloride, printed wiring boards and children's products. Manufacturers, including Albemarle Corp., Chevron and Ferro Corp., reported making or importing 10.7 million pounds in 2011.

EPA Makes Public Comprehensive Information on Use of Chemicals in the U.S.

The U.S. Environmental Protection Agency (EPA) has released the 2012 Chemical Data Reporting (CDR) information on more than 7,600 chemicals in commerce. The CDR database contains comprehensive use and exposure information on the most widely used chemicals in the United States.

Companies are now required to provide information on chemicals used in children’s and other consumer products, along with reports on commercial applications and industrial uses of chemicals. For the first time ever, EPA also required companies to substantiate confidentiality claims in order to ensure that as much information as possible is made available to the public.

“The 2012 Chemical Data Reporting information will help EPA and others better assess chemicals, evaluate potential exposures and use, and expand efforts to encourage the use of safer chemicals,” said EPA Administrator Lisa P. Jackson. “The CDR data also highlight the clear need for TSCA reform. Updating this critical law will ensure that EPA has access to the tools and resources it needs to quickly and effectively assess potentially harmful chemicals, and safeguard the health of families across the country.”

The CDR rule, the source of this new data, was issued under the Toxic Substances Control Act (TSCA). The rule requires companies that manufacture or import chemicals to report manufacturing and import data every four years when site-specific production volume exceeds 25,000 lb. This report is for calendar year 2011. The EPA received reports on 7,674 chemicals, including 354 that were reported as used in children’s products. 1,704 chemicals were reported as used in consumer products and 3,073 were used in commercial applications or products. The remaining chemicals reported were for industrial use only. The CDR information includes data on chemicals that are used in children’s products such as toys, playground and sporting equipment, arts and crafts materials, and textiles and furniture.

Chemicals used in consumer products, particularly those intended for children, present potential for direct exposure to the public and are priorities for assessment by the agency. Although reporting on these chemicals is compulsory, currently there are no requirements under TSCA that existing chemicals be evaluated for safety.

Yet EPA has taken action and begun a process to ensure that chemicals used by the public on a daily basis are safe. The process identifies potential chemicals for near-term review and risk assessment under TSCA. In 2012, EPA released a work plan of 83 chemicals for further review as part of the agency’s existing chemicals management program. From that list, seven chemicals were identified for risk assessment development in 2012 and 18 for assessment in 2013 and 2014. In January, 2013, EPA released for public comment and peer review an initial set of draft risk assessments of five chemicals for particular uses found in common household products
