ACTION: Notice of availability. 

SUMMARY: This notice announces the 

availability of the Toxicological Profile 

for Toxaphene (Update) and the 

Toxicological Profile for 

Trichlorobenzenes for review and 

comment. We are seeking public 

comments for review and potential 

inclusion in the profiles. These 

comments can include additional 

information or reports on studies about 

the health effects of toxaphene and 

trichlorobenzenes. ATSDR remains 

committed to providing a public 

comment period for these documents to 

best serve public health and our clients. 

The Comprehensive Environmental 

Response, Compensation, and Liability 

Act of 1980 (CERCLA), as amended by 

the Superfund Amendments and 

Reauthorization Act of 1986 (SARA), 

section 104(i)(3), [42 U.S.C. 9604(i)(3)], 

directs the ATSDR administrator to 

prepare toxicological profiles of priority 

hazardous substances and, as necessary, 

to revise and publish each updated 

toxicological profile. 

DATES: To be considered, comments on 

these draft toxicological profiles must be 

received not later than February 25, 

2011. Comments received after the close

SUPPLEMENTARY INFORMATION: The 

Superfund Amendments and 

Reauthorization Act (SARA) (Pub. L. 

99–499) amends the Comprehensive 

Environmental Response, 

Compensation, and Liability Act 

(CERCLA or Superfund) (42 U.S.C. 9601 

et seq.) by establishing certain 

responsibilities for ATSDR and the U.S. 

Environmental Protection Agency (U.S. 

EPA) with regard to hazardous 

substances most commonly found at 

facilities on the CERCLA National 

Priorities List (NPL). As part of these 

responsibilities, the ATSDR 

administrator must prepare 

toxicological profiles for substances 

enumerated on the priority list of 

hazardous substances. This list 

identifies 275 hazardous substances 

that, according to ATSDR and U.S. EPA, 

pose the most significant potential 

threat to human health. The availability 

of the revised priority list of 275 

hazardous substances was announced in 

the Federal Register on March 6, 2008 

(73 FR 12178). In addition, ATSDR has 

the authority to prepare toxicological 

profiles for substances not found at sites 

on the NPL, in an effort to ‘‘* * * 

establish and maintain inventory of 

literature, research, and studies on the 

health effects of toxic substances’’ under 

CERCLA Section 104(i)(1)(B), to respond 

to requests for consultation under 

CERCLA Section 104(i)(4), and as 

otherwise necessary to support the sitespecific response actions conducted by 

ATSDR. 

Each profile will include an 

examination, a summary, and an 

interpretation of available toxicological 

information and epidemiological 

evaluations. This information and these 

data identify the levels of significant 

human exposure for the substances and 

for the associated health effects. The 

profiles must also include a 

determination of whether adequate 

information on the health effects of each 

substance is available or is being 

developed. If adequate information is 

not available, ATSDR, in cooperation 

with the National Toxicology Program 

(NTP), is required to ensure the 

initiation of research to determine such 

health effects. 

Although ATSDR considered key 

studies for each of the substances during 

the profile development process, this 

Federal Register notice solicits any 

relevant, additional studies, particularly 

unpublished data and ongoing studies. 

ATSDR will evaluate such data or 

studies for possible addition to the 

profiles, now or in the future. All 

toxicological profiles issued as ‘‘Drafts 

for Public Comment’’ represent ATSDR’s 

best efforts to provide crucial 

toxicological information on priority 

hazardous substances. 

The draft toxicological profiles will be 

made available to the public on or about 

October 17, 2010.
