ENVIRONMENTAL PROTECTION 

AGENCY

[OPPT–2004–0130; FRL–7692–1]

Fifty-Fifth 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 FiftyFifth Report to the Administrator of EPA 

on December 8, 2004. In the 55th ITC 

Report, which is included with this 

notice, the ITC is revising the Priority 

Testing List by adding a category of high 

production volume (HPV) orphan 

chemicals and requesting that EPA add 

these chemicals to the TSCA section 

8(a) Preliminary Assessment 

Information Reporting (PAIR) rule and 

the TSCA section 8(d) Health and Safety 

Data Reporting (HaSDR) rule. The ITC is 

also removing the following chemicals 

from the Priority Testing List: 3-amino5-mercapto-1,2,4-triazole; glycoluril; 

benzenamine, 3-chloro-2,6-dinitro-N,Ndipropyl-4-(trifluoromethyl)-; stannane, 

dimethylbis[(1-oxoneodecyl)oxy]-; 

benzene, 1,3,5-tribromo-2-(2-

propenyloxy)-; and1-triazene, 1,3-

diphenyl-.]. Since the 55th Report was 

ITC transmitted to the Administrator 

and made publicly available on http://

www.epa.gov/opptintr/itc/, five HPV 

orphan chemicals have been removed 

from the Priority Testing List because 

chemical manufacturers committed to 

prepare robust summaries for these 

chemicals in response to the HPV 

Challenge Program. The ITC encourages 

other manufacturers to make similar 

commitments so their chemicals can be 

removed from the Priority Testing List

and potentially avoid being added to 

PAIR and HaSDR rules.

DATES: Comments, identified by docket 

identification (ID) number OPPT–2004–

0130, must be received on or before 

March 14, 2005.

ADDRESSES: Comments may be 

submitted electronically, by mail, or

holidays. The telephone number for the 

DCO is (202) 564–8930.

D. How Should I Submit CBI to the 

Agency?

Do not submit information that you 

consider to be CBI electronically 

through EPA’s electronic public docket 

or by e-mail. You may claim 

information that you submit to EPA as 

CBI by marking any part or all of that 

information as CBI (if you submit CBI 

on disk or CD ROM, mark the outside 

of the disk or CD ROM as CBI and then 

identify electronically within the disk or 

CD ROM the specific information that is 

CBI). Information so marked will not be 

disclosed except in accordance with 

procedures set forth in 40 CFR part 2.

In addition to one complete version of 

the comment that includes any 

information claimed as CBI, a copy of 

the comment that does not contain the 

information claimed as CBI must be 

submitted for inclusion in the public 

docket and EPA’s electronic public 

docket. If you submit the copy that does 

not contain CBI on disk or CD ROM, 

mark the outside of the disk or CD ROM 

clearly that it does not contain CBI. 

Information not marked as CBI will be 

included in the public docket and EPA’s 

electronic public docket without prior 

notice. If you have any questions about 

CBI or the procedures for claiming CBI, 

please consult the technical person 

listed under FOR FURTHER INFORMATION

CONTACT.

E. What Should I Consider as I Prepare 

My Comments for EPA?

notice.

6. To ensure proper receipt by EPA, 

be sure to identify the docket ID number 

assigned to this action in the subject 

line on the first page of your response. 

You may also provide the name, date, 

and Federal Register citation.

II. Background

The Toxic Substances Control Act 

(TSCA) (15 U.S.C. 260l et seq.) 

authorizes the Administrator of the EPA 

to promulgate regulations under section 

4(a) of TSCA 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 the 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.

A. The ITC’s 55th Report

The 55th ITC Report was transmitted 

to EPA’s Administrator on December 8, 

7366 Federal Register / Vol. 70, No. 28 / Friday, February 11, 2005 / Notices 

2004, and is included in this notice. In 

the 55th ITC Report, the ITC is revising 

the Priority Testing List by adding a 

category of HPV orphan chemicals and 

requesting that EPA add these chemicals 

to the TSCA section 8(a) PAIR rule and 

the TSCA section 8(d) HaSDR rule. The 

ITC is also removing the following 

chemicals from the Priority Testing List: 

3-amino-5-mercapto-1,2,4-triazole; 

glycoluril; benzenamine, 3-chloro-2,6-

dinitro-N,N-dipropyl-4-

(trifluoromethyl)-; stannane, 

dimethylbis[(1-oxoneodecyl)oxy]-; 

benzene, 1,3,5-tribromo-2-(2-

Summary

In this 55th ITC Report, the ITC is revising 

the Priority Testing List by adding a category 

of High Production Volume (HPV) orphan 

chemicals and requesting that EPA add these 

chemicals to the Toxic Substances Control 

Act (TSCA) section 8(a) Preliminary 

Assessment Information Reporting (PAIR) 

rule and the TSCA section 8(d) Health and 

Safety Data Reporting (HaSDR) rule. The ITC 

is also removing the following chemicals 

from the Priority Testing List: 3-amino-5-

mercapto-1,2,4-triazole; glycoluril; 

benzenamine, 3-chloro-2,6-dinitro-N,Ndipropyl-4-(trifluoromethyl)-; stannane,

I. Background

The ITC was established by section 4(e) of 

TSCA ‘‘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/

opptintr/itc/) within a few days of 

submission to the Administrator and from 

the EPA’s web site http://www.epa.gov/

fedrgstr/ after publication in the Federal 

Register. The ITC produces its revisions to 

the Priority Testing List with administrative 

and technical support from the ITC Staff and 

ITC Members and their U.S. Government 

organizations, and contract support provided 

by EPA. ITC Members and Staff are listed at 

the end of this report.

II. TSCA Section 8 Reporting

A. TSCA Section 8 Reporting Rules

Following receipt of the ITC’s Report (and 

the revised Priority Testing List) by the EPA 

Administrator, the EPA’s Office of Pollution 

Prevention and Toxics (OPPT) may add the 

chemicals from the revised Priority Testing 

List to the TSCA section 8(a) Preliminary 

Assessment Information Reporting (PAIR) 

and TSCA section 8(d) Health and Safety 

Data Reporting (HaSDR) rules. The PAIR rule 

requires producers and importers of 

chemicals added to the Priority Testing List

to submit production and exposure reports 

(http://www.epa.gov/opptintr/chemtest/

pairform.pdf/). The HaSDR rule requires 

producers, importers and processors of all 

chemicals added to the Priority Testing List

to submit unpublished health and safety 

studies under TSCA section 8(d) that must be 

in compliance with the revised HaSDR rule 

(Ref. 1). All submissions must be received by 

the EPA within 90 days of the reporting rules 

Federal Register publication date.

Federal Register / Vol. 70, No. 28 / Friday, February 11, 2005 / Notices 7367

B. ITC’s Use of TSCA Section 8 and Other 

Information

The ITC’s use of TSCA section 8 and other 

information is described in previous ITC 

Reports (http://www.epa.gov/opptintr/itc/

rptmain.htm/).

C. Previous Requests to Add Chemicals to the 

TSCA Section 8(a) PAIR Rule

In its 53rd Report, the ITC requested that 

EPA add 3 pyridinamines and 20 tungsten 

compounds to the TSCA section 8(a) PAIR 

rule (Ref. 2). On December 7, 2004, EPA 

issued a final rule, pursuant to TSCA section 

8(a) requiring producers and importers of 

these 23 chemicals to report production, 

importation, and exposure data to EPA (Ref. 

3).

D. New Requests to Add Chemicals to the 

TSCA Section 8(a) PAIR and 8(d) HaSDR 

Rules

In this report, the ITC is requesting that 

EPA add the HPV orphan chemicals listed in 

Appendix A to the TSCA section 8(a) PAIR 

and 8(d) HaSDR rules. The ITC is requesting 

that these HPV orphan chemicals be added 

to the TSCA section 8(a) PAIR and 8(d) 

HaSDR rules because no voluntary studies 

have been submitted to the EPA in response 

to the HPV Challenge Program (http://

www.epa.gov/opptintr/chemrtk/volchall.htm/

).

III. ITC’s Activities During this Reporting 

Period (May to November 2004)

During this reporting period, the ITC 

reviewed the reports submitted in response 

to the June 11, 2003, PAIR rule (Ref. 4) and 

the May 4, 2004, TSCA section 8(d) HaSDR 

rule (Ref. 5). The ITC is continuing to review 

these reports.

The ITC also met with EPA to discuss 

procedures for making data publicly 

available on HPV orphan chemicals (HPV 

chemicals for which no sponsors have 

volunteered to develop and submit robust 

summaries to the EPA). The ITC’s 

discussions with EPA are described in 

section IV. of this report.

As noted in the 51st and 54th ITC Reports 

(Refs. 6 and 7), the ITC continues to request 

the following information on vanadium 

compounds:

1. Recent non-CBI estimates of annual 

production or importation volume data and 

trends, and use information, including 

percentages of production or importation that 

are associated with different uses.

2. Estimates of the number of humans and 

concentrations of vanadium chemicals to 

which humans may be exposed in each 

relevant manufacturing or processing 

scenario.

3. Health effects data including 

pharmacokinetics, genotoxicity, subchronic 

toxicity, reproductive and developmental 

toxicity, and any human data from 

occupationally exposed workers.

The ITC seeks this information in order to 

adequately assess the extent and degree of 

exposure and potential hazard associated 

with the various forms of vanadium.

In addition, the ITC is concerned that some 

of these compounds may be released into fly 

ash ponds at power plants, petroleum and 

chemical refineries, and mining sites and 

could be toxic to avian and wildlife species 

as exemplified by a recent report of dead and 

dying Canada geese at a petroleum refinery 

fly ash pond in Delaware. In these geese, the 

vanadium concentrations in pooled liver and 

kidney samples were 57 and 226 μg/gram (g) 

dry weight, respectively. Background 

concentrations of vanadium in various 

tissues of higher vertebrates, including 

waterfowl, rarely exceed 1 μg/g dry weight. 

Limited data are available on vanadium 

toxicity in birds and other wildlife making it 

difficult to interpret the findings from the 

geese die-off.

The ITC knows that vanadium is released 

into impoundments at 172 facilities in 33 

states and that the TRI does not have 

vanadium concentrations for these 

impoundments. The ITC is soliciting data on 

concentrations and species of vanadium 

compounds in impoundments at power 

plants, petroleum and chemical refineries, 

and mining sites and information on the use, 

release, and presence of vanadium 

compounds at these facilities. The ITC needs 

these data and information to determine if 

avian wildlife in the vicinity of the 172 

facilities are at risk from exposure to 

vanadium compounds. If you have any 

questions regarding the applicability of this 

action to a particular entity, consult the 

technical person listed under FOR FURTHER

INFORMATION CONTACT.

IV. Revisions to the TSCA Section 4(e) 

Priority Testing List

A. Chemicals Added to the Priority Testing 

List: HPV Orphan Chemicals

1. Recommendation. EPA requests that the 

ITC add the category HPV orphan chemicals 

listed in Appendix A of this report to the 

Priority Testing List to obtain importation, 

production, use, and exposure information as 

well as unpublished physical/chemical 

property, environmental fate, health effects, 

and ecological effects information to meet 

U.S. Government data needs.

2. Rationale for recommendation. While 

the success of the HPV Challenge Program 

has been significant, hundreds of chemicals 

that were eligible for sponsorship in the 

Program continue to remain unsponsored. 

These chemicals are referred to as ‘‘orphans.’’

There is little or no publicly available 

information regarding the potential hazards 

associated with these chemicals. EPA 

remains committed to obtain basic screening 

level hazard information on these chemicals 

through voluntary sponsorship, as well as 

through TSCA information gathering and test 

rules, as necessary.

3. Supporting information. In developing 

the list of HPV orphan chemicals presented 

in Appendix A of this report, EPA considered 

all of the HPV orphan chemicals and then 

removed selected HPV orphan chemicals. 

The HPV orphan chemicals presented in 

Appendix A of this report do not include 

those HPV orphan chemicals that: 

a. Had 2002 Inventory Update rule 

reported production/importation volumes >

one million pounds (http://www.epa.gov/

oppt/iur/iur02/index.htm/ ) and were 

proposed for testing in the first HPV test rule 

(Ref. 8).

b. Meet the ‘‘No Longer HPV’’ criteria (i.e., 

chemicals with production/importation 

volumes < 1 million pounds based on 1998 

and 2002 Inventory Update Rule data (http:/

/www.epa.gov/oppt/iur/iur02/index.htm/)).

c. Are being considered for a second HPV 

TSCA section 4 test rule because they may 

meet the TSCA section 4(a)(1)(B) statutory 

requirements.

At EPA’s request, the ITC encourages 

manufacturers of these chemicals to visit the 

EPA’s HPV Challenge Program web site 

(http://www.epa.gov/opptintr/chemrtk/

volchall.htm/) and to make a commitment to 

sponsor these chemicals at the present time, 

before regulatory actions are initiated. EPA 

will initiate development of TSCA section 

8(a) PAIR and 8(d) HaSDR rules soon after 

these chemicals are added to the Priority 

Testing List and the ITC’s 55th Report is 

published in the Federal Register. Also at 

EPA’s request, the ITC encourages the 

submission of robust summaries of studies 

submitted under the TSCA section 8(d) 

HaSDR rule to facilitate EPA’s review of the 

unpublished TSCA section 8(d) studies (see 

USEPA. 1999. Draft Guidance on Developing 

Robust Summaries. October 22, 1999 (http:/

/www.epa.gov/chemrtk/robsumgd.htm/)). 

While some of the HPV orphan chemicals 

have been previously added to the TSCA 

section 8(d) HaSDR rule, all of the sunset 

dates for these chemicals have expired (see 

Appendix A of this report), thus new and so 

far unreported studies would need to be 

submitted. Information about the 

environmental fate and potential hazards 

associated with these chemicals when 

combined with information about exposure 

and uses will allow the EPA and others to 

evaluate and prioritize potential health and 

environmental effects and determine the 

need for test rules under TSCA section 4(a). 

If you have any questions regarding the 

applicability of this action to a particular 

entity, consult the technical person listed 

under FOR FURTHER INFORMATION CONTACT.

4. Information needs. For each individual 

substance listed in Appendix A of this report, 

EPA needs the following information to 

assess the extent and degree of exposure and 

potential hazard associated with these 

substances:

a. Production, importation, processing, use 

and associated exposure information that is 

captured under the TSCA section 8(a) PAIR 

form.

b. Unpublished studies of:

i. Physical/chemical properties and 

environmental fate for the properties listed in 

40 CFR 716.50 as well as melting point and 

boiling point.

ii. Health effects including 

pharmacokinetics, genotoxicity, acute 

toxicity, subacute toxicity, subchronic 

toxicity, chronic toxicity, reproductive 

toxicity, developmental toxicity, 

immunotoxicity, neurotoxicity, and 

oncogenicity/carcinogenicity.

iii. Ecological effects including acute and 

chronic toxicity studies of aquatic and 

terrestrial vertebrates and invertebrates and 

aquatic plants. 

c. Only studies where the recommended 

HPV orphan chemical is ≥ 90% of the test 

substance by weight should be submitted. In 

7368 Federal Register / Vol. 70, No. 28 / Friday, February 11, 2005 / Notices 

addition, only studies that were conducted 

using TSCA, Federal Insecticide, Fungicide, 

and Rodenticide Act (FIFRA), Organization 

for Economic Cooperation and Development 

(OECD), or other internationally accepted test 

guidelines or voluntary consensus standards 

should be submitted. Studies performed 

where the recommended HPV orphan 

chemical is < 90% of the test substance by 

weight are not requested at this time.

B. Chemicals Removed From the Priority 

Testing List

1. 3-Amino-5-mercapto-1,2,4-triazole. 3-

Amino-5-mercapto-1,2,4-triazole (Chemical 

Abstracts Service Registry Number (CAS No.) 

16691–43–3 ) was added to the Priority 

Testing List in the ITC’s 42nd Report to obtain 

annual production/importation volumes and 

trends, use, exposure, and health effects data 

(Ref. 9). The addition was based on concerns 

that 3-amino-5-mercapto-1,2,4-triazole was 

structurally related to 3-amino-1,2,4-triazole 

(Amitrol), a herbicide that affects thyroid 

hormone activity (Ref. 10). In response to the 

ITC’s request, the EPA added 3-amino-5-

mercapto-1,2,4-triazole to the July 24, 2000, 

PAIR rule (Ref. 11) and the May 4, 2004 

HaSDR rule (Ref. 5). Numerous studies were 

submitted in response to the HaSDR rule. 

These studies are summarized in this unit. 3-

Amino-5-mercapto-1,2,4-triazole was positive 

in the mouse bone marrow micronucleus test, 

clastogenic to rat lymphocytes, but not 

mutagenic in the Ames assay using strains 

TA98, 100, 1535, and 1537 or in the E. coli

assay, using strain WP2 uvrA-. 3-Amino-5-

mercapto-1,2,4-triazole was a mild eye and 

skin irritant, but not a skin sensitizer. In a 4-

week inhalation study the no observed effect 

level of 3-amino-5-mercapto-1,2,4-triazole 

was 20 milligram/meter cubed (mg/m3).

3-Amino-5-mercapto-1,2,4-triazole is being 

removed from the Priority Testing List

because information submitted in response to 

the PAIR rule suggested that 3-amino-5-

mercapto-1,2,4-triazole is an on-site 

intermediate and the production/importation 

volumes were lower than the 250,000 pounds 

of 3-amino-5-mercapto-1,2,4-triazole 

imported into the United States in 1993 (Ref. 

9).

2. Glycoluril. Glycoluril (CAS No. 496–46–

8) was also added to the Priority Testing List

in the ITC’s 42nd Report to obtain annual 

production/importation volumes and trends, 

use, exposure, and health effects data. The 

addition was based on a potential for human 

exposure and a suspicion of carcinogenicity 

(Ref. 9). In response to the ITC’s request, the 

EPA added glycoluril to the July 24, 2000 

PAIR rule (Ref. 11) and the May 4, 2004 

HaSDR rule (Ref. 5). No studies were 

submitted in response to the HaSDR rule.

Glycoluril is being removed from the 

Priority Testing List because information 

submitted in response to the PAIR rule 

suggested that glycoluril is an on-site 

intermediate and the production/importation 

volumes were less than the 10,000 to 

1,000,000 pounds of non-CBI annual 

production/importation volumes reported to 

the EPA in 1986, 1990, and 1994 (Ref. 9).

3. Benzenamine, 3-chloro-2,6-dinitro-N,Ndipropyl-4-(trifluoromethyl)-. Benzenamine, 

3-chloro-2,6-dinitro-N,N-dipropyl-4-

(trifluoromethyl)- (aka 3-Chlorotrifluralin 

(CAS No. 29091–20–1) was added to the 

Priority Testing List in the ITC’s 48th Report 

to obtain information on uses, exposures, 

environmental releases, pharmacokinetics, 

subchronic toxicity, mutagenicity, 

reproductive and developmental effects, 

carcinogenicity, and ecological effects (Ref. 

12). Benzenamine, 3-chloro-2,6-dinitro-N,Ndipropyl-4-(trifluoromethyl)- was added to 

the Priority Testing List because it has an 

estimated bioconcentration factor (BCF) of 

7,700 and is a chlorinated analog of 

trifluralin (CAS No. 1582–09–8), the 

herbicide that causes adverse effects in 

experimental animals and is considered to be 

a possible human carcinogen by the EPA 

(Ref. 12).

In response to the ITC’s request, the EPA 

added benzenamine, 3-chloro-2,6-dinitroN,N-dipropyl-4-(trifluoromethyl)- to the June 

11, 2003 PAIR rule (Ref. 4) and the May 4, 

2004 TSCA section 8(d) HaSDR rule (Ref. 5). 

No information was submitted in response to 

the PAIR or HaSDR rules. The ITC is 

removing benzenamine, 3-chloro-2,6-dinitroN,N-dipropyl-4-(trifluoromethyl)- from the 

Priority Testing List because the PAIR rule 

did not provide any additional exposure 

information implying that benzenamine, 3-

chloro-2,6-dinitro-N,N-dipropyl-4-

(trifluoromethyl)- is not produced at greater 

than 1,000 pounds per site.

4. Stannane, dimethylbis[(1-

oxoneodecyl)oxy]-. Stannane, dimethylbis[(1-

oxoneodecyl)oxy]- (CAS No. 68928–76–7) 

was added to the Priority Testing List in the 

ITC’s 49th Report to obtain use, exposure, 

environmental fate, health effects, and 

ecological effects data (Ref. 13). Stannane, 

dimethylbis[(1-oxoneodecyl)oxy]- was added 

to the Priority Testing List because it has an 

estimated BCF of 8,600 and signs of toxicity, 

including neurotoxic effects that were 

observed in a rat oral gavage study (Ref. 13).

In response to the ITC’s request, the EPA 

added stannane, dimethylbis[(1-

oxoneodecyl)oxy]- to the June 11, 2003 PAIR 

rule (Ref. 4) and the May 4, 2004 TSCA 

section 8(d) HaSDR rule (Ref. 5). No 

information was submitted in response to the 

HaSDR rule. The ITC is removing stannane, 

dimethylbis[(1-oxoneodecyl)oxy]- from the 

Priority Testing List because the information 

submitted in response to the PAIR rule 

suggested that the production/importation 

volumes of stannane, dimethylbis[(1-

oxoneodecyl)oxy]- were not greater than the 

10,000–500,000 pounds of non-CBI 

production/importation volumes reported to 

the EPA in 2002 (http://www.epa.gov/oppt/

iur/iur02/index.htm/).

5. Benzene, 1,3,5-tribromo-2-(2-

propenyloxy)-. Benzene, 1,3,5-tribromo-2-(2-

propenyloxy)- (CAS No. 3278–89–5) was 

added to the Priority Testing List in the ITC’s 

50th Report to obtain use, exposure, 

environmental fate, health effects, and 

ecological effects data (Ref. 14). Benzene, 

1,3,5-tribromo-2-(2-propenyloxy)- was added 

to the Priority Testing List because of an 

estimated BCF of 4,000 and potential for 

exposure from its use as a flame retardant for 

expanded polystyrene insulation board (Ref. 

14).

In response to the ITC’s request, the EPA 

added benzene, 1,3,5-tribromo-2-(2-

propenyloxy)- to the June 11, 2003 PAIR rule 

(Ref. 4) and the May 4, 2004 TSCA section 

8(d) HaSDR rule (Ref. 5). Information 

submitted in response to the HaSDR rule 

indicated that the concentrated chemical may 

be slightly irritating to the skin. The ITC is 

removing benzene, 1,3,5-tribromo-2-(2-

propenyloxy)- from the Priority Testing List

because the information submitted in 

response to the PAIR rule suggested that the 

production/importation volumes of benzene, 

1,3,5-tribromo-2-(2-propenyloxy)- were not 

greater than 10,000–500,000 pounds of nonCBI production/importation volumes 

reported to the EPA in 2002 (http://

www.epa.gov/oppt/iur/iur02/index.htm/).

6. 1-Triazene, 1,3-diphenyl-. 1-Triazene, 

1,3-diphenyl- (aka diazoaminobenzene (CAS 

No. 136–35–6) was added to the Priority 

Testing List in the ITC’s 50th Report to obtain 

annual production/importation volumes and 

trends, use, exposure, and health effects data 

(Ref. 14). 1-Triazene, 1,3-diphenyl- was 

added to the Priority Testing List because it 

is a predicted carcinogen based on its 

metabolism and similarity in toxic effects to 

benzene and aniline (Ref. 14).

In response to the ITC’s request, the EPA 

added 1-triazene, 1,3-diphenyl- to the June 

11, 2003 PAIR rule (Ref. 4) and the May 4, 

2004 TSCA section 8(d) HaSDR rule (Ref. 5). 

No information was submitted in response to 

the PAIR or HaSDR rules. The ITC is 

removing 1-triazene, 1,3-diphenyl- from the 

Priority Testing List because the PAIR rule 

did not provide any additional exposure 

information implying that 1-triazene, 1,3-

diphenyl- is not produced at greater than 

1,000 pounds per site.
