Availability of Work Plan Chemical Problem Formulation and 
Initial Assessment and Data Needs Assessment Documents for Flame 
Retardant Clusters; Notice and Public Comment Periods

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: EPA is announcing the availability and opening of a 60-day 
public comment period for TSCA Work Plan Chemical problem formulation 
and initial assessment documents for three flame retardant clusters. 
EPA is also making available and opening a 120-day public comment 
period for the TSCA Work Plan Chemical data needs assessment document 
for the Brominated Phthalates flame retardant cluster. Based on 
experience in conducting TSCA Work Plan Chemical assessments and public 
input, starting in 2015 EPA will publish a problem formulation and 
initial assessment, or a data needs assessment, for each TSCA Work Plan 
assessment as a stand-alone document to facilitate public input prior 
to conducting further risk analysis. EPA believes publishing problem 
formulation and initial assessment documents for TSCA Work Plan 
assessments will increase transparency about EPA's thinking and 
analysis process, provide opportunity for the public to comment on 
EPA's approach, and give EPA the opportunity to receive additional 
information/data prior to EPA conducting detailed risk analysis

and risk characterization. There are three clusters of flame retardant 
on the TSCA Work Plan for which there are problem formulation and 
initial assessment documents: Brominated Bisphenol A, Chlorinated 
Phosphate Esters, and Cyclic Aliphatic Bromides. In addition, there is 
a data needs assessment document for the Brominated Phthalates flame 
retardant cluster. There is a separate docket assigned to each TSCA 
Work Plan Chemical flame retardant cluster.

DATES: Comments on the three problem formulation and initial assessment 
documents (Brominated Bisphenol A (TBBPA), Chlorinated Phosphate Esters 
(CPE), and Cyclic Aliphatic Bromides (HBCD)) must be received on or 
before October 19, 2015. Comments on the data needs assessment document

A. Docket ID Number EPA-HQ-OPPT-2015-0068

    Title: TSCA Work Plan Chemical Problem Formulation and Initial 
Assessment: Chlorinated Phosphate Esters Cluster.
    Chemicals covered: Ethanol, 2-chloro-, phosphate (3:1) (TCEP) 
(CASRN: 115-96-8); 2-Propanol, 1-chloro-, 2,2',2''-phosphate (TCPP) 
(CASRN: 13674-84-5); and 2-Propanol, 1,3-dichloro-, phosphate (3:1) 
(TDCPP) (CASRN: 13674-87-8).
    Summary: Chlorinated phosphate esters are high production volume 
chemicals that have been used as flame retardants in furniture foams, 
textiles, paints and coatings. EPA initiated scoping and problem 
formulation to determine the feasibility of conducting a quantitative 
risk assessment. During problem formulation, EPA reviewed previous 
assessments by EPA and other organizations and additional published 
studies on the exposure and hazard for members of the CPE cluster. EPA 
examined likely exposure and hazard scenarios based on current 
production, use, and fate information to identify scenarios amenable to 
a risk analysis.

B. Docket ID Number EPA-HQ-OPPT-2015-0081

    Title: TSCA Work Plan Chemical Problem Formulation and Initial 
Assessment: Cyclic Aliphatic Bromides Cluster.
    Chemicals covered: Hexabromocyclododecane (HBCD, CASRN 25637-99-4); 
1,2,5,6,9,10-Hexabromocyclododecane (CASRN 3194-55-6); and 1,2,5,6-
Tetrabromocyclooctane (CASRN 3194-57-8).
    Summary: Cyclic Aliphatic Bromides have been used as a flame 
retardant in: extruded and expanded polystyrene foams (EPS/XPS), 
polystyrene (PS) products, textiles, paints and coatings. EPA initiated 
scoping and problem formulation to determine the feasibility of 
conducting a quantitative risk assessment. During problem formulation, 
EPA reviewed previous assessments by EPA and other organizations and 
additional published studies on the exposure and hazard for members of 
this flame retardant cluster. EPA examined likely exposure and hazard 
scenarios based on current production, use, and fate information to 
identify scenarios amenable to a risk analysis. During problem 
formulation, EPA identified inhalation, dermal and lifetime exposure 
assessments as data gaps that add uncertainty to EPA's risk

TBBPA-bis(dibromopropyl ether) (CASRN 21850-44-2); TBBPA-bis(ally 
ether) (CASRN 25327-89-3); and TBBPA-bis(methyl ether) (CASRN 37853-61-
5).
    Summary: Tetrabromobisphenol A is a compound commonly used as a 
flame retardant in plastics/printed circuit boards for electronics and 
has been found in children's products and other consumer products. EPA 
initiated scoping and problem formulation to determine the feasibility 
of conducting a quantitative risk assessment. During problem 
formulation, EPA reviewed previous assessments by EPA and other 
organizations and additional published studies on the exposure and 
hazard for members of this flame retardant cluster. EPA examined likely 
exposure and hazard scenarios based on current production, use, and 
fate information to identify scenarios amenable to a risk analysis.

D. Docket ID Number EPA-HQ-OPPT-2014-0491

    Title: TSCA Work Plan Chemical Problem Formulation and Data Needs 
Assessment: Brominated Phthalates Cluster.
    Chemicals covered: 1,2-Benzenedicarboxylic acid, 3,4,5,6-
tetrabromo-, 1,2-bis(2-ethylhexyl) ester (TBPH) (CASRN 26040-51-7); 
Benzoic acid, 2,3,4,5-tetrabromo-, 2-ethylhexyl ester (TBB) (CASRN: 
183658-27-7); 1,2-Benzenedicarboxylic acid, 3,4,5,6-tetrabromo-, 1-[2-
(2-hydroxyethoxy)ethyl] 2-(2-hydroxypropyl) ester (CASRN: 20566-35-2);

7415-86-3); Chemical A--Chemical Identity claimed confidential by 
manufacturer; Chemical B--Chemical Identity claimed confidential by 
manufacturer.
    Summary: The Brominated Phthalates Cluster is a group of seven 
chemicals at least two of which, TBB and TBPH, are found in commercial 
flame retardant formulations. During problem formulation, EPA reviewed 
previous assessments by EPA and other organizations and additional 
published studies on the exposure and hazard for members of the 
Brominated Phthalates Cluster. This review identified critical data 
gaps and uncertainties that limit EPA's ability to conduct a 
quantitative risk assessment for any of the chemicals in the Brominated 
Phthalates cluster. Specifically, the review identified numerous gaps 
in toxicity data and exposure data, testing conducted on limited 
commercial mixtures but not all constituents of the mixtures, and 
uncertain attribution of toxicity for commercial mixtures. As an 
initial step toward conducting a robust risk assessment, EPA is 
releasing a ``Data Needs Assessment'' for the Brominated Phthalates 
Cluster. This Data Needs Assessment is intended to guide the collection 
of additional data and information to fill the critical data gaps and 
reduce uncertainties identified during problem formulation.
    If you have any questions about any of these problem formulation 
and initial assessment documents and the data needs assessment 
document, or the Agency's programs in general, please contact the 
person listed under FOR FURTHER INFORMATION CONTACT.
