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 multi- mode 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 web- based 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:

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

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-of- scientific-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.
