Abstract: The U.S. Environmental 

Protection Agency’s (EPA) Chesapeake 

Bay Program (the Program) is interested 

in tracking its progress at attaining its 

goals under the 2014 Chesapeake Bay 

Watershed Agreement (the Agreement). 

To do this, the Program plans to 

implement three surveys: The Citizen 

Stewardship Survey, the Diversity 

Profile Survey, and the Local 

Leadership Survey. 

EPA has specified the target audience 

and the implementation approach for 

each to maximize the data that can be 

obtained. The Citizen Stewardship 

Survey will be implemented as a multimode survey that includes phone, web, 

and mail components of residents living 

the Chesapeake Bay area, stratified by 

jurisdiction (states and the District of 

Columbia). The Diversity Profile Survey 

will be implemented among people who 

work on partnership efforts within the 

Bay area as a web-based survey. The 

Local Leadership Survey will be 

implemented among state and local 

elected officials involved in policy 

making in the Bay area also as a webbased survey. 

The Program will be using the data 

from these three surveys to track it 

progress under the Stewardship goal of 

the 2014 Agreement. The Stewardship 

goal includes three outcomes: (1) 

Citizen Stewardship, (2) Local 

Leadership, and (3) Diversity. Three 

surveys under this ICR each address one 

of the outcomes and contributes to 

EPA’s Government Performance and 

Results Act (GPRA) goals (EPA Goal 1, 

A Cleaner, Healthier Environment; 

Objective 1.2: Provide for Clean and 

Safe Water). 

Each of the surveys under this ICR 

were funded and implemented by other 

partners in the Chesapeake Bay area in 

prior years. The Program determined 

that the best approach for continued 

implementation of these surveys would 

be for the EPA assume the responsibility 

for implementing these surveys; thus, 

EPA is seeking approval for 

implementing these surveys under this 

ICR. 

Collecting these data and publishing 

them for public review will allow the 

public to track how well the Agreement 

is working to preserve and protect the 

Chesapeake Bay region from the 

standpoint of the Stewardship goal 

outlined in the Agreement. Overall, the 

Agreement contains 10 goals and their 

associated outcomes; data for the other 

nine goals are collected through other 

means. Combining the data for 

Stewardship goal outcomes from these 

surveys with the data for the other nine 

goals will provide the public will have 

a comprehensive picture of the progress 

being made to preserve and protect 

Chesapeake Bay. 

Form Numbers: None. 

Respondents/affected entities: 

Stewardship survey: Members of the 

general public; Local Leaders survey: 

Individuals in local government 

leadership roles; Diversity Profile 

survey: Individuals working at 

organizations to conserve/restore 

Chesapeake Bay. 

Respondent’s obligation to respond: 

Voluntary. 

Estimated number of respondents: 

6,430 (total). 

Frequency of response: Once. 

Total estimated burden: 2,298 hours 

(total). Burden is defined at 5 CFR 

1320.03(b). 

Total estimated cost: $100,931 (total), 

includes $0 annualized capital or 

operation & maintenance costs. 

Changes in the Estimates: This is a 

new collection.

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 

entities that manufacture (including 

import) a chemical substance regulated 

under TSCA, 15 U.S.C. 2601 et seq., 

(e.g., entities identified under North 

American Industrial Classification 

System (NAICS) codes 325 and 324110). 

The action may also be of interest to 


jbell on DSKJLSW7X2PROD with NOTICES
50348 Federal Register / Vol. 86, No. 171 / Wednesday, September 8, 2021 / Notices 

chemical processors, distributors in 

commerce, and users; non-governmental 

organizations in the environmental and 

public health sectors; state and local 

government agencies; and members of 

the public. Since other entities may also 

be interested, the Agency has not 

attempted to describe all the specific 

entities and corresponding NAICS codes 

for entities that may be interested in or 

affected by this action. 

B. What is the Agency’s authority for 

taking this action? 

The draft scope of the risk evaluation 

is issued pursuant to TSCA 

implementing regulations at 40 CFR 

702.41(c)(7). 

C. What action is the Agency taking? 

EPA is publishing and requesting 

public comment on the draft scope of 

the risk evaluation for D4 under TSCA. 

Through the risk evaluation process, 

EPA will determine whether the 

chemical substance presents an 

unreasonable risk of injury to health or 

the environment under the conditions of 

use, as determined by the 

Administrator, in accordance with 

TSCA section 6(b)(4). 

II. Background 

TSCA allows chemical manufacturers 

to request an EPA-conducted risk 

evaluation of a chemical substance 

under 40 CFR 702.37. On March 19, 

2020, EPA received a manufacturer 

request for a risk evaluation of D4. In 

the Federal Register notice of June 17, 

2020 (85 FR 36586; FRL–10010–49), 

EPA opened a 45-day public comment 

period to gather information relevant to 

the requested risk evaluation. EPA 

granted the request on October 6, 2020, 

and subsequently initiated the scoping 

process for the risk evaluation for this 

chemical substance on November 5, 

2020. The purpose of a risk evaluation 

is to determine whether a chemical 

substance, or group of chemical 

substances, presents an unreasonable 

risk to health or the environment, under 

the conditions of use, including an 

unreasonable risk to a relevant 

potentially exposed or susceptible 

subpopulation (15 U.S.C. 2605(b)(4)(A)). 

As part of this process, EPA must 

evaluate both hazards and exposures for 

the conditions of use; describe whether 

aggregate or sentinel exposures were 

considered and the basis for 

consideration; not consider costs or 

other non-risk factors; take into account 

where relevant, likely duration, 

intensity, frequency, and number of 

exposures; and describe the weight-ofscientific-evidence for hazards and 

exposures (15 U.S.C. 2605(b)(4)(F)). This 

process will culminate in a 

determination of whether or not the 

chemical substance presents an 

unreasonable risk of injury to health or 

the environment under the conditions of 

use (15 U.S.C. 2605(b)(4)(A); 40 CFR 

702.47). 

III. Draft Scope of the Risk Evaluation 

for Octamethylcyclotetra-Siloxane (D4) 

The chemical substance for which 

EPA is publishing the draft scope of the 

risk evaluation is listed on the TSCA 

Inventory with CA Index Name 

‘‘Cyclotetrasiloxane, 2,2,4,4,6,6,8,8- 

octamethyl-’’ and the associated 

Chemical Abstracts Service Registry 

Number (CASRN) 556–67–2. The draft 

scope of the risk evaluation for this 

chemical substance includes the 

conditions of use, hazards, exposures, 

and the potentially exposed or 

susceptible subpopulations EPA plans 

to consider in the risk evaluation (15 

U.S.C. 2605(b)(4)(D)). Development of 

the scope is the first step of a risk 

evaluation. The draft scope of the risk 

evaluation will include the following 

components (40 CFR 702.41(c)): 

• The conditions of use, as 

determined by the Administrator, that 

EPA plans to consider in the risk 

evaluation. 

• The potentially exposed 

populations that EPA plans to evaluate; 

the ecological receptors that EPA plans 

to evaluate; and the hazards to health 

and the environment that EPA plans to 

evaluate. 

• A description of the reasonably 

available information and the science 

approaches that the Agency plans to 

use. 

• A conceptual model that will 

describe the actual or predicted 

relationships between the chemical 

substance, the conditions of use within 

the scope of the evaluation and the 

receptors, either human or 

environmental, with consideration of 

the life cycle of the chemical 

substance—from manufacturing, 

processing, distribution in commerce, 

storage, use, to release or disposal—and 

identification of human and ecological 

health hazards EPA plans to evaluate for 

the exposure scenarios EPA plans to 

evaluate. 

• An analysis plan, which will 

identify the approaches and methods 

EPA plans to use to assess exposure, 

hazards, and risk, including associated 

uncertainty and variability, as well as a 

strategy for using reasonably available 

information and science approaches. 

• A plan for peer review. 

EPA encourages commenters to 

provide information they believe might 

be missing or may further inform the 

risk evaluation. EPA will publish a 

notice in the Federal Register 

announcing the availability of the final 

scope of the risk evaluation within three 

months of publishing the draft scope. 

Authority: 15 U.S.C. 2601 et seq.
