ENVIRONMENTAL PROTECTION 

AGENCY 

[EPA–HQ–OPPT–2013–0248; FRL–9391–5] 

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. 

DATES: Comments must be received on 

or before August 23, 2013.

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. 

A. The 72nd ITC Report

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 nonphthalate 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 biomonitoring 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 


emcdonald on DSK67QTVN1PROD with NOTICES2
Federal Register / Vol. 78, No. 142 / Wednesday, July 24, 2013 / Notices 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

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.
