Federal Register / Vol. 75, No. 94 / Monday, May 17, 2010 / Notices 27553 

conjunction with other agencies, is 

currently developing Bay-wide 

pollutant reduction goals that will 

ultimately be used to establish total 

maximum daily loads (TMDL) under 

Section 303(d) of the Clean Water Act 

for the Chesapeake Bay watershed. The 

TMDL will be followed by the 

development of watershed 

implementation plans in 92 Bay subwatersheds that will have had load and 

wasteload allocations assigned based on 

the TMDL and the Chesapeake Bay 

model. While the Section 502 guidance 

is required to be published before the 

TMDL is finalized, we expect that the 

TMDL and sub-watershed allocations 

will clarify that the nonpoint sources in 

the Chesapeake Bay watershed will 

need to be controlled, and be controlled 

well, in order to restore the Bay. This 

guidance should help land managers 

identify and select practices that should 

provide the needed level of control. 

This guidance has chapters 

addressing the following categories of 

activity (excluding sources regulated as 

point sources): Agriculture; Urban and 

Suburban areas, including Turf; 

Decentralized Wastewater Treatment 

Systems; Forestry; Riparian Areas; and 

Hydromodification. Each chapter 

contains implementation measures that 

provide the framework for the chapter. 

These are intended to convey the 

essential actions that will need to be 

implemented in order to assure that the 

broad goals of the Chesapeake Bay 

Executive Order can be achieved. Each 

chapter also includes information on 

practices that can be used to achieve the 

goals; information on the effectiveness 

and costs of the practices; where 

relevant, cost savings or other 

economic/societal benefits (in addition 

to the pollutant reduction benefits) that 

derive from the implementation goals 

and/or practices; and copious references 

to other documents that provide 

additional information. 

EPA emphasizes that this is not a 

regulatory document. At the same time 

it is important to realize that Section 

501 of the Executive Order directs 

federal agencies with ten or more acres 

within the Chesapeake Bay watershed to 

implement the Section 502 guidance as 

expeditiously as practicable and to the 

extent permitted by law. While this 

guidance may at times refer to existing 

statutory and regulatory provisions that 

contain legally binding requirements, 

this document does not substitute for 

those provisions or regulations, nor is it 

a regulation itself. Thus, it does not 

impose legally binding requirements on 

EPA, states, or the public and might not 

apply to a particular situation according 

to the circumstances. EPA and state 

decision makers retain the discretion to 

adopt approaches to control nonpoint 

source pollution that differ from this 

guidance where appropriate, and EPA 

may change this guidance in the future. 

How can I get copies of this document 

and other related information? 

EPA Web site: EPA published the 

guidance on May 12, 2010, on our Web 

site at http://www.epa.gov/nps/ 

chesbay502. On this Web site, the 

guidance can be downloaded in full or 

by chapter. Also available on this Web 

site are a summary of the suite of 

implementation measures described and 

a response to public and peer review 

comments.

SUPPLEMENTARY INFORMATION: Pursuant 

to the Federal Advisory Committee Act 

(FACA), 5 U.S.C., App. 2, notice is 

hereby given that the EPA Science 

Advisory Board will hold a public 

teleconference to review three draft SAB 

reports: (1) The SAB Environmental 

Engineering Committee Hydraulic 

Fracturing Research Plan Review; (2) the 

report from the SAB Work Group to 

Lead the Review of the Arsenic Cancer 

Assessment; and (3) the chartered SAB’s 

draft report on Strategic Research 

Directions and Integrated 

Transdisciplinary Research. The SAB 

was established pursuant to 42 U.S.C. 

4365 to provide independent scientific 

and technical advice to the 

Administrator on the technical basis for 

Agency positions and regulations. The 

SAB is a Federal Advisory Committee 

under FACA. The SAB will comply 

with the provisions of FACA and all 

appropriate SAB Staff Office procedural 

policies. 

Background: (1) Advisory on EPA’s 

Proposed Hydraulic Fracturing Research 

Plan Review. In its Fiscal Year 2010 

Appropriation Conference Committee 

Directive to EPA, the U.S. House of 

Representatives approved a provision 

that urges EPA to assess the potential 

risks to drinking water posed by 

hydraulic fracturing of formations 

including coalbeds and shale for 

extraction of natural gas. Hydraulic 

fracturing generates vertical and 

horizontal fractures in underground 

geologic formations to facilitate 

extraction of gas (or oil) from the 

subsurface.

27554 Federal Register / Vol. 75, No. 94 / Monday, May 17, 2010 / Notices 

To meet the Congressional request, 

EPA’s Office of Research and 

Development (ORD) developed a draft 

research plan. This plan described an 

approach to gather existing data and 

information including a stakeholder 

input process; to catalog potential risks 

to drinking water supplies from 

hydraulic fracturing; to identify data 

gaps; and to develop research questions, 

research needs, and research products. 

ORD requested SAB advice regarding 

the planned research. The SAB 

Environmental Engineering Committee 

discussed its advice on April 7–8, 2010 

(75 FR 9205–9206). Background 

information about this advisory activity

(2) Review of the Arsenic Cancer 

Assessment: EPA is currently in the 

process of updating the 1988 IRIS 

cancer assessment for inorganic arsenic. 

The EPA evaluated and implemented 

the National Research Council 

recommendations in their report titled 

Arsenic in Drinking Water: 2001 Update 

and in 2005 requested the SAB review 

the Agency’s draft cancer assessment for 

inorganic arsenic. The SAB review 

report (Advisory on EPA’s Assessments 

of Carcinogenic Effects of Organic and 

Inorganic Arsenic: A Report of the US 

EPA Science Advisory Board, EPA– 

SAB–07–008) was finalized in 2007. 

EPA’s Office of Research 

Development has recently completed a 

2010 draft titled: ‘‘Toxicological Review 

of Inorganic Arsenic: In Support of the 

Summary Information on the Integrated 

Risk Information System (IRIS)’’. ORD 

requested that the SAB evaluate and 

comment on EPA’s interpretation and 

implementation of the key SAB (2007) 

recommendations. ORD requested a 

review focusing in three areas of the 

draft cancer assessment of inorganic 

arsenic: Evaluation of epidemiological 

literature; dose-response modeling 

approaches; and the sensitivity analysis 

of the exposure assumptions used in the 

risk assessment. 

A work group of the chartered SAB 

discussed its review on April 6–7, 2010 

(75 FR 9205–9206). Background 

information about this advisory activity

(3) Chartered SAB’s draft report on 

strategic research directions and 

integrated transdisciplinary research: 

Since 2007 EPA’s ORD has requested 

SAB advice on strategic research 

directions. ORD requested advice on the 

overall strategic direction of the 

program in relation to EPA’s overall 

mission and components of EPA’s 

research program. The draft report was 

developed after SAB discussions with 

ORD about strategic research directions 

on November 9–10, 2009 (74 FR 52805– 

52806) and April 5–6, 2010 (75 FR 

11883–11884).

Availability of Meeting Materials: The 

agenda and other materials in support of 

the teleconference will be placed on the 

SAB Web site at http://www.epa.gov/sab 

in advance of the teleconference. 

Procedures for Providing Public Input: 

Public comment for consideration by 

EPA’s Federal advisory committees and 

panels has a different purpose from 

public comment provided to EPA 

program offices. Therefore, the process 

for submitting comments to a Federal 

advisory committee is different from the 

process used to submit comments to an 

EPA program office. 

Federal advisory committees and 

panels, including scientific advisory 

committees, provide independent 

advice to EPA. Members of the public 

can submit comments for a Federal 

advisory committee to consider as it 

develops advice for EPA. They should 

send their comments directly to the 

Designated Federal Officer for the 

relevant advisory committee. Oral 

Statements: In general, individuals or 

groups requesting time to make an oral 

presentation at a public SAB 

teleconference will be limited to three 

minutes, with no more than one-half 

hour for all speakers. Those interested 

in being placed on the public speakers 

list should contact Dr. Nugent at the 

contact information provided above by 

June 9, 2010. Written Statements: 

Written statements should be received 

in the SAB Staff Office by June 9, 2010. 

Written statements should be supplied 

to the DFO via e-mail to nugent.angela

@epa.gov (acceptable file format: Adobe 

Acrobat PDF, WordPerfect, MS Word, 

MS PowerPoint, or Rich Text files in 

IBM–PC/Windows 98/2000/XP format). 

Submitters are asked to provide versions 

of each document submitted with and 

without signatures, because the SAB 

Staff Office does not publish documents 

with signatures on its Web sites. 

Accessibility: For information on 

access or services for individuals with 

disabilities, please contact Dr. Angela 

Nugent at (202) 343–9981 or nugent.

angela@epa.gov. To request 

accommodation of a disability, please 

contact her preferably at least 10 days 

prior to the teleconference, to give EPA 

as much time as possible to process 

your request.

SUPPLEMENTARY INFORMATION: EPA is 

revising an assessment for arsenic in 

support of EPA’s Integrated Risk 

Information System (IRIS). The National 

Research Council (NRC) published 

reports on the health effects of arsenic 

in 1999 and 2001. Since 2001, 

information has been developed for 

dermal hyperpigmentation, keratosis, 

and epidemiology of inorganic arsenic 

that may impact EPA’s 1988 values. The 

IRIS Program is preparing an assessment 

which will incorporate available 

noncancer health effects information for 

inorganic arsenic, as well as new risk 

assessment methods. ORD has requested 

that the SAB conduct the external peer 

review of its revised draft assessment.
