Abstract: Government surveillance of 

contractor performance is required to 

give reasonable assurance that efficient 

methods and effective cost controls are 

being used for various cost-reimbursable 

and fixed-rate contracts. Per 48 CFR 

1552.211 regulations, the Agency on a 

monthly basis requires contractors to 

provide the Contracting Officer’s 

Representative (COR) with a report 

detailing: a) what was accomplished on 

the contract for that period, b) 

expenditures for the same period of 

time, and c) what is expected to be 

accomplished on the contract for the 

next month. Responses to the 

information collection are mandatory 

for contractors and are required for the 

contractors to receive monthly 

payments. 

Form Numbers: 1900–68. 

Respondents/affected entities: Private 

contractors. 

Respondent’s obligation to respond: 

Mandatory (48 CFR 1552.211). 

Estimated number of respondents: 

266 (total). 

Frequency of response: Monthly. 

Total estimated burden: 77,406 hours 

(per year). Burden is defined at 5 CFR 

1320.03(b) 

Total estimated cost: $7,207,568 (per 

year), includes $39,900 annualized 

capital or operation & maintenance 

costs. 

Changes in the Estimates: There is an 

increase of 16,506 hours in the total 

estimated respondent burden compared 

with the ICR currently approved by 

OMB. This is due to an increase in the 

number of contracts that are being 

awarded.

SUPPLEMENTARY INFORMATION: 

I. General Information 

A. Does this action apply to me? 

This action is directed to the public 

in general, and may be of interest to a 


asabaliauskas on DSK5VPTVN1PROD with NOTICES
23546 Federal Register / Vol. 80, No. 81 / Tuesday, April 28, 2015 / Notices 

wide range of stakeholders including 

those interested in environmental and 

human health; the chemical industry; 

chemical users; consumer product 

companies and members of the public 

interested in the assessment of chemical 

risks. Since others also may be 

interested, the Agency has not 

attempted to describe all the specific 

entities that may be affected by this 

action. 

B. What should I consider as I prepare 

my comments for EPA? 

1. Submitting CBI. Do not submit this 

information to EPA through 

regulations.gov or email. Clearly mark 

the part or all of the information that 

you claim to be CBI. For CBI 

information in a disk or CD–ROM that 

you mail to EPA, 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 claimed as CBI. In addition to one 

complete version of the comment that 

includes 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. Information so marked 

will not be disclosed except in 

accordance with procedures set forth in 

40 CFR part 2. 

2. Tips for preparing your comments. 

When preparing and submitting your 

comments, see the commenting tips at 

http://www.epa.gov/dockets/

comments.html. 

II. What action is the Agency taking? 

EPA is announcing that it will be 

publishing a problem formulation and 

initial assessment or data needs 

assessment document for each TSCA 

Work Plan Chemical prior to conducting 

further risk analysis. Based on 

experience in conducting TSCA Work 

Plan Chemical assessments to date and 

stakeholder feedback, starting in 2015 

EPA will publish a problem formulation 

and initial assessment or data needs 

assessment document for each TSCA 

Work Plan Chemical as a stand-alone 

document. A problem formulation and 

initial assessment document will serve 

to inform the public and other 

interested stakeholders about EPA’s 

initial scoping of findings and plan for 

any further risk assessment. Problem 

formulation and initial assessment is the 

analytical phase of the assessment in 

which the purpose for the assessment is 

articulated, the problem defined and a 

plan for analyzing and characterizing 

risk is determined. 

Outcomes of a problem formulation 

and initial assessment are: (a) 

Conceptual Model—including a visual 

representation and written description 

of actual or predicted relationships 

between chemicals and human or 

wildlife; (b) Analysis Plan—describing 

the intentions regarding the technical 

aspects of the risk assessment. In some 

instances, as a result of problem 

formulation and initial assessment, EPA 

identifies data gaps (uses, exposure 

pathways, toxicity data) so significant as 

to prevent conducting a meaningful risk 

assessment. In these cases, EPA will 

publish a Data Needs Assessment 

document and provide opportunity for 

the public and stakeholders to 

comment, identify or provide data or 

information that may fill identified data 

gaps prior to EPA pursing data 

collection via TSCA authorities. 

To facilitate public and stakeholder 

input prior to conducting further risk 

analysis, EPA will open a public docket 

for receiving comments, data or 

information from interested 

stakeholders when it publishes each 

problem formulation and initial 

assessment or data needs assessment 

document. EPA believes publishing 

problem formulation and initial 

assessment documents for TSCA Work 

Plan Chemicals will increase 

transparency of EPA’s thinking and 

analysis process, provide opportunity 

for the public and stakeholders to 

comment on EPA’s approach and 

provide additional information or data 

to supplement or refine assessment 

approaches prior to EPA conducting 

detailed risk analysis and risk 

characterization. Following receipt of 

comments on the problem formulation 

and initial assessment document and 

consideration of any additional data or 

information received, EPA will initiate 

a risk assessment which is the process 

to estimate the nature and probability of 

adverse health and environmental 

effects in humans and ecological 

receptors from chemical contaminants 

that may be present in the environment. 

EPA is also announcing the 

availability of the TSCA Work Plan 

Chemical Problem Formulation and 

Initial Assessment for 1,4-Dioxane for 

public comment. 1,4-Dioxane is the first 

chemical for which EPA is releasing a 

problem formulation and initial 

assessment document under the TSCA 

Work Plan Chemical Assessment 

Program. 1,4-Dioxane is a chemical that 

is used primarily as a solvent in the 

manufacture of other chemicals. 1,4- 

Dioxane is also found as an impurity in 

anti-freeze and aircraft deicing fluids 

and in some consumer products 

[deodorants, shampoos, and cosmetics] 

(ATSDR 2012; EPA 2006; Mohr 2001). 

During problem formulation and initial 

assessment, EPA reviewed previous 

assessments by EPA and other 

organizations and additional published 

studies on the exposure and hazard of 

1,4-Dioxane. EPA examined likely 

exposure and hazard scenarios based on 

current production, use, and fate 

information to identify scenarios 

amenable to a risk analysis. The data 

available and scenarios evaluated for 

conducting a risk assessment are 

provided in EPA’s TSCA Work Plan 

Chemical Problem Formulation and 

Initial Assessment for 1,4-Dioxane. The 

conclusions of the problem formulation 

and initial assessment are: (a) EPA will 

further assess potential risks to workers 

exposed during product formulation 

and use as a cleaning agent; (b) EPA will 

further assess potential risks to workers 

and consumers exposed during the use 

of TSCA-use products that contain 1,4- 

Dioxane as a contaminant, such as 

paints, varnishes, adhesives, cleaners 

and detergents; (c) Risk to the general 

population through inhalation exposure 

to ambient air emissions is estimated to 

be low; (d) An assessment of risk from 

exposure through drinking water is not 

needed at this time because 1,4-Dioxane 

is currently being monitored and EPA 

will determine whether or not 

regulatory action is needed as part of its 

Regulatory Determination Process; (e) 

Based on the low hazard profile for 1,4- 

Dioxane to aquatic organisms, risks to 

these organisms are expected to be low. 

EPA does not have the hazard data 

needed to determine if there are risks to 

sediment and soil organisms. Therefore, 

further analysis of environmental risk is 

not planned. EPA plans to review and 

evaluate the results of previous 

exposure assessments and health 

benchmarks for this chemical. As a 

result, EPA/OPPT will develop margins 

of exposure and cancer risk estimates to 

evaluate the potential risks from worker 

and consumer exposure to 1,4-Dioxane. 

Use the docket ID number: EPA–HQ– 

OPPT–2015–0078 to locate a copy of the 

1,4-Dioxane problem formulation and 

initial assessment document, as well as 

to submit comments via http://

www.regulations.gov.
