Seventy-Second Report of the TSCA Interagency Testing Committee 
to the Administrator of the Environmental Protection Agency; Receipt of 
Report and Request for Comments

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY: The Toxic Substances Control Act (TSCA) Interagency Testing 
Committee (ITC) transmitted its 72nd ITC Report to the Acting EPA 
Administrator on June 13, 2013. In the 72nd ITC Report, which is 
included with this notice, the ITC is revising the TSCA section 4(e) 
Priority Testing List by removing 16 chemicals with insufficient dermal 
absorption rate data, 98 High Production Volume (HPV) Challenge Program 
orphan chemicals, and 50 diisocyanates and related compounds. The ITC 
is removing 16 chemicals with insufficient dermal absorption rate data 
because information from dermal studies can be readily obtained through 
the Organization for Economic Cooperation and Development (OECD) and 
EPA databases or other authoritative scientific resources. The ITC is 
removing the 98 HPV Challenge Program orphan chemicals because they no 
longer meet the = 1 million lb criterion for the HPV 
Challenge Program. The ITC is removing the 50 diisocyanates and related 
compounds because their production or importation volumes were not 
reported to the 2006 Inventory Update Reporting (IUR) rule or the 2012 
Chemical Data Reporting (CDR) rule.

II. Background

    The Toxic Substances Control Act (TSCA) (15 U.S.C. 260l et seq.) 
authorizes the Administrator of EPA to promulgate regulations under 
TSCA section 4(a) requiring testing of chemicals and chemical groups in 
order to develop data relevant to determining the risks that such 
chemicals and chemical groups may present to health or the environment. 
Section 4(e) of TSCA established the ITC to recommend chemicals and 
chemical groups to the Administrator of EPA for priority testing 
consideration. Section 4(e) of TSCA directs the ITC to revise the TSCA 
section 4(e) Priority Testing List at least every 6 months.
    You may access additional information about the ITC at http://www.epa.gov/oppt/itc.

I. Background

    The ITC was established by TSCA section 4(e) ``to make 
recommendations to the Administrator respecting the chemical substances 
and mixtures to which the Administrator should give priority 
consideration for the promulgation of rules for testing under section 
4(a) * * * At least every six months * * *, the Committee shall make 
such revisions to the Priority Testing List as it determines to be 
necessary and transmit them to the Administrator together with the 
Committee's reasons for the revisions'' (Public Law 94-469, 90 Stat. 
2003 et seq., 15 U.S.C. 2601 et seq.). ITC reports are available from 
the ITC's Web site (http://www.epa.gov/oppt/itc) and from 
regulations.gov (http://www.regulations.gov) after publication in the 
Federal Register. The ITC produces its revisions to the TSCA section 
4(e) Priority Testing List with administrative and technical support 
from the ITC staff and ITC members. ITC members and staff are listed at 
the end of this report.

II. ITC's Activities During This Reporting Period (December 2012 to May 
2013)

    The ITC welcomed a new member and new alternate member from the 
Department of Commerce's National Institute of Standards and Technology 
and a new member from the National Science Foundation.
    During this reporting period, the ITC discussed the 16 chemicals 
with insufficient dermal absorption rate data, branched 4-nonylphenol 
(mixed isomers), phenol, 4-(1,1,3,3-tetramethylbutyl)-, 148 HPV 
Challenge Program orphan chemicals, cadmium and cadmium compounds, 6 
non-phthalate plasticizers, 25 phosphate ester and 2 other flame 
retardants, 9 chemicals to which children living near hazardous waste 
sites may be exposed, and 69 diisocyanates and related compounds 
remaining on the TSCA section 4(e) Priority Testing List. As a result 
of these discussions, the ITC removed 16 chemicals with insufficient 
dermal absorption rate data, 98 HPV Challenge Program orphan chemicals, 
and 50 diisocyanates and related compounds from the TSCA section 4(e) 
Priority Testing List. Orphan chemicals are those HPV chemicals for 
which no sponsors have volunteered to develop and submit robust 
summaries of basic hazard and fate testing data to the EPA. The hazard 
and fate testing data requested by the EPA for HPV Challenge Program 
orphan chemicals are necessary to establish a screening level 
understanding of their potential human health and environmental 
impacts. The chemicals with insufficient dermal absorption rate data, 
HPV Challenge Program orphan chemicals and diisocyanates and related 
compounds are discussed further in Unit III. of this 72nd ITC Report.
    As noted in this unit, the ITC also discussed the following 
chemicals that remain on the TSCA section 4(e) Priority Testing List: 
Branched 4-nonylphenol (mixed isomers), phenol, 4-(1,1,3,3-
tetramethylbutyl)-, cadmium and cadmium compounds, 6 non-phthalate 
plasticizers, 25 phosphate ester flame retardants, 2 other flame 
retardants, and 9 chemicals to which children living near hazardous 
waste sites may be exposed.
    Branched 4-nonylphenol (mixed isomers) (CAS No. 84852-15-3) and 
phenol, 4-(1,1,3,3-tetramethylbutyl)- (CAS No. 140-66-9) were added to 
the TSCA section 4(e) Priority Testing List in the ITC's 37th and 41st 
Reports along with numerous other alkylphenols, alkylphenol 
ethoxylates, and poly alkylphenols (Refs. 1 and 2). The remaining data 
needed for branched 4-nonylphenol (mixed isomers) and phenol, 4-
(1,1,3,3-tetramethylbutyl)- can be obtained from avian reproduction 
testing and fish multi-generation testing, respectively. Branched 4-
nonylphenol (mixed isomers) and phenol, 4-(1,1,3,3-tetramethylbutyl)- 
will remain on the TSCA section 4(e) Priority Testing List until the 
avian reproduction testing and fish multi-generation testing is 
completed or other information becomes available to justify removing 
them from the TSCA section 4(e) Priority Testing List.
    Cadmium and cadmium compounds were added to the TSCA section 4(e) 
Priority Testing List in the ITC's 68th and 69th Reports (Refs. 3 and 
4). Cadmium and cadmium compounds were included in a TSCA section 8(d) 
Health and Safety Data Reporting (HaSDR) rule that was published in the 
Federal Register of December 3, 2012 (77 FR 71561) (FRL-9355-9). After 
receiving adverse comments to the HaSDR rule, EPA published a document 
withdrawing the HaSDR rule in the Federal Register of December 28, 2012 
(77 FR 76419) (FRL-9375-3) due to questions and concerns raised about 
the scope and extent of the HaSDR rule. EPA is considering the 
questions and concerns raised in response to the HaSDR rule and next 
steps with regard to that rule.
    Six non-phthalate plasticizers, 25 phosphate ester flame 
retardants, and 2 other flame retardants were added to the TSCA section 
4(e) Priority Testing List in the ITC's 69th Report (Ref. 4). They were 
added to obtain existing bio-monitoring data on urinary metabolites 
that will be used to assess the risks of these chemicals. The 2 other 
flame retardants, 1,2-benzenedicarboxylic acid, 3,4,5,6-tetrabromo-, 
1,2-bis(2-ethylhexyl) ester, a.k.a. bis(2-ethyl-1-hexyl) 
tetrabromophthalate (CAS No. 26040-51-7) and benzoic acid, 2,3,4,5-
tetrabromo-, 2-ethylhexyl ester, a.k.a. 2-ethylhexyl-2,3,4,5-
tetrabromobenzoate (CAS No. 183658-27-7) are included in the assessment 
strategy that EPA developed for brominated phthalates (http://www.epa.gov/oppt/existingchemicals/pubs/2013wpractivities.html).
    The U.S. Department of the Interior (DOI) and Environment Canada 
are collaborating on a study involving exposure of American Kestrels 
(Falco sparverius) to 4 of the phosphate ester flame retardants 
discussed in the ITC's 69th Report (Ref. 4). The 4 phosphate ester 
flame retardants include: Ethanol, 2-butoxy-, 1,1',1''-phosphate, 
a.k.a. tri(2-butoxyethyl) phosphate (CAS No. 78-51-3); ethanol, 2-
chloro-, phosphate (3:1), a.k.a. tris(2-chloroethyl) phosphate (CAS No. 
115-96-8); 2-propanol, 1-chloro-, 2,2',2''-phosphate, a.k.a. tris(1-
chloro-2-propyl)phosphate (CAS No. 13674-84-5) and 2-propanol, 1,3-
dichloro-, phosphate (3:1), a.k.a. tris(1,3-dichloro-2-propyl) 
phosphate (CAS: 13674-87-8). The study will provide novel 
information on uptake kinetics and potential toxicity of priority 
phosphate ester flame retardants that are currently found in wild bird 
eggs in North America. One of these phosphate ester flame retardants, 
ethanol, 2-chloro-, phosphate (3:1), a.k.a. tris(2-chloroethyl) 
phosphate (CAS No. 115-96-8) is included in the risk assessment 
strategy that EPA is developing for chlorinated phosphate esters 
(http://www.epa.gov/oppt/existingchemicals/pubs/2013wpractivities.html).
    Nine chemicals to which children living near hazardous waste sites 
may be exposed were added to the TSCA section 4(e) Priority Testing 
List in the ITC's 69th Report (Ref. 4). They were added to obtain 
existing biomonitoring data on blood levels that will be used to fill 
priority data needs that were identified during the development of 
ATSDR's Toxicological Profiles. Priority data needs are published in 
the Federal Register and represent a wide variety of needs, including 
biomonitoring studies to help establish reference values for exposed 
populations as well as background levels for the general population 
(http://www.atsdr.cdc.gov/pdns/index.asp). The 9 chemicals to which 
children living near hazardous waste sites may be exposed are from the 
current unfilled priority data needs and any biomonitoring data will be 
used to conduct public health assessments. The EPA is deliberating 
options for satisfying the data needs for these 9 chemicals.

III. Chemicals Removed From the TSCA Section (4)(e) Priority Testing 
List

A. Chemicals With Insufficient Dermal Absorption Rate Data

    In its 31st, 32nd, and 35th ITC Reports, the Occupational Safety 
and Health Administration (OSHA) requested that the ITC add 24, 34, and 
25 chemicals, respectively, to the TSCA section 4(e) Priority Testing 
List and designate them for testing to develop dermal absorption rate 
data (Refs. 5, 6, and 7). The ITC removed methyl methacrylate and 
diethyl phthalate from the TSCA section 4(e) Priority Testing List in 
its 34th ITC Report (Ref. 8) and cyclohexanone from the TSCA section 
4(e) Priority Testing List in its 36th ITC Report (Ref. 9). Methyl 
methacrylate, diethyl phthalate, and cyclohexanone

[[Page 44861]]

were removed from the TSCA section 4(e) Priority Testing List because 
dermal absorption rate data were identified after these chemicals were 
added to the TSCA section 4(e) Priority Testing List. In its 45th ITC 
Report (Ref. 10), the ITC removed 47 chemicals designated for dermal 
absorption rate testing from the TSCA section 4(e) Priority Testing 
List, because the EPA published a rule proposing dermal absorption rate 
testing for these chemicals (Ref. 11). In 2004, the EPA reviewed more 
recent production volume, exposure, and dermal absorption rate data and 
promulgated a rule requiring dermal absorption rate testing for 34 of 
these chemicals (Ref. 12). The rationales for EPA's decision not to 
finalize testing requirements for the other 13 chemicals in the 
proposed rule are described in Ref. 11. In its 59th ITC Report, the ITC 
removed 16 more chemicals with insufficient dermal absorption rate data 
from the TSCA section 4(e) Priority Testing List (Ref. 13). The ITC 
removed these 16 chemicals because their production volumes indicated 
low potential for occupational exposures. In this 72nd ITC Report, the 
ITC is removing the 16 remaining chemicals with insufficient dermal 
absorption rate data from the TSCA section 4(e) Priority Testing List 
(Table 2 of this unit). OSHA determined that for these 16 chemicals, 
information from dermal studies can be readily obtained through the 
OECD existing chemical database (eChemPortal), the EPA HPV database 
(High Production Volume Information System (HPVIS) or other 
authoritative scientific resources (Ref. 14). The ITC is removing these 
chemicals as a result of OSHA's determination that sufficient 
information is currently available on the dermal absorption 
characteristics of these chemicals to warrant their removal from the 
TSCA section 4(e) Priority Testing List.

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

B. HPV Challenge Program Orphan Chemicals

    In 2004, at the EPA's request, the ITC added 281 HPV Challenge 
Program orphan (unsponsored) chemicals to the TSCA section 4(e) 
Priority Testing List in the ITC's 55th and 56th Reports (Refs. 15 and 
16). As of December 2012, 133 HPV Challenge Program orphan chemicals 
had been removed from the TSCA section 4(e) Priority Testing List 
because they were included in EPA's test rules, the testing was 
voluntarily sponsored or because they no longer met the  1 
million lb criterion for the HPV Challenge Program. Based on data 
received from the 2006 IUR rule, and the 2012 CDR rule, EPA identified 
98 HPV Challenge Program orphan chemicals with production volumes 
consistently below 1 million lb. Since these 98 chemicals no longer 
exceed the 1 million lb criterion for the HPV Challenge Program, EPA is 
requesting their removal from the TSCA section 4(e) Priority Testing 
List in this 72nd ITC Report (Ref. 17). The 98 HPV Challenge Program

C. Diisocyanates and Related Compounds

    At the request of the current EPA member to the ITC, 69 
diisocyanates and related compounds were added to the TSCA section 4(e) 
Priority Testing List in the ITC's 69th Report. They were added to 
obtain numerous data on diisocyanates and related compounds used to 
formulate a broad class of polyurethane products (e.g., sealants, 
adhesives, etc.) that are intended to further react upon end-use (Ref. 
4). The EPA determined that 50 of these diisocyanates and related 
compounds were not reported to the EPA's 2006 IUR and 2012 CDR rules. 
Since these 50 diisocyanates and related compounds were not reported to 
the EPA's 2006 IUR and 2012 CDR rules, EPA is requesting their removal 
from the TSCA section 4(e) Priority Testing List in this 72nd ITC 
Report (Ref. 17). The 50 diisocyanates and related compounds being 
removed from the TSCA section 4(e) Priority Testing List are listed in 
Table 5 of this unit. The 19 diisocyanates and related compounds 
remaining on the TSCA section 4(e) Priority Testing List are listed in 
Table 6 of this unit.
