compound. While ‘‘n’’ and ‘‘m’’ are integers in any single molecule, the Galden HTFs are typically made up of mixtures of different molecules. 

The values for ‘‘n’’ and ‘‘m’’ for any single Galden HTF represent averages for that HTF. Table 2 provides the ranges of the average values of 

‘‘n’’ and ‘‘m’’ for the Solvay HTFs in each Galden series (Galden HT, LS, etc.). 

IV. Summary of EPA Assessment of 

Submitted GWPs and the Data and 

Analysis Supporting Them 

The EPA completed a review of the 

GWPs listed in Table 1 of this notice 

and the data and analysis submitted in 

support of them. That assessment is 

available in the docket, together with 

the submitted data and analyses. In 

general, we found that the data and 

methods used to estimate the GWPs 

were reasonable and that the GWPs 

were consistent with what would be 

expected for compounds of the types 

analyzed. However, there were some 

limitations to the data and analysis. 

First, in some cases the transparency of 

the data and analysis were limited 

because some of the reports containing 

the detailed background information 

were not available for review in time for 

this notice. Second, some of the data 

were of uncertain quality because they 

were based on an unpublished master’s 

thesis. Third, because some of the 

analyses were performed in the early 

1990s, some of the models used to 

estimate lifetimes or radiative 

efficiencies were out of date. Fourth, in 

one case (PTAA), radiative efficiency 

estimates were based on a quantitative 

structural activity relationship (QSAR) 

of uncertain predictive ability. Fifth, the 

atmospheric lifetime for one of the 

short-lived compounds (HFE–7300) was 

estimated based on an atmospheric 

lifetime for methane that is lower than 

the currently accepted lifetime, 

resulting in an underestimated lifetimes 

for that compound. Finally, for the six 

long-lived compounds, experimental 

limitations prevented 3M or its 

researchers from establishing more than 

minimum atmospheric lifetimes, and 

the GWPs based on these lifetimes are 

therefore also minimums. 

Overall, we do not expect that these 

limitations resulted in large errors in the 

resulting GWPs; and with the exception 

of the errors attributable to the last two 

issues (related to atmospheric lifetimes), 

we expect that these are random rather 

than systematic errors. To address the 

last two issues, we examined the 

sensitivity of the GWPs of the 

compounds to atmospheric lifetime. In 

general, 100-year GWPs for very longlived compounds are relatively 

insensitive to increases in assumed 

atmospheric lifetime, and our analysis 

confirmed this. However, the 100-year 

GWPs for the short-lived compounds are 

sensitive to increases in the assumed 

atmospheric lifetime. For example, 

updating the atmospheric lifetime for 

HFE–7300 based on the currently 

accepted atmospheric lifetime of 

methane increases the estimated GWP of 

HFE–7300 by 10 percent.

SUPPLEMENTARY INFORMATION: 

Background: The SAB was 

established pursuant to the 

Environmental Research, Development, 

and Demonstration Authorization Act 

(ERDDAA), codified at 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 chartered under 

the Federal Advisory Committee Act 

(FACA), 5 U.S.C., App. 2. The SAB will 

comply with the provisions of FACA 

and all appropriate SAB Staff Office 

procedural policies. Pursuant to FACA 

and EPA policy, notice is hereby given 

that the SAB will hold a public meeting 

and public teleconference to receive 

public comments and to provide an 

opportunity for independent expert 

members of the SAB Panel to discuss, 

deliberate, and provide comment on the 

topics below. 

In response to public concern, 

Congress directed EPA to study the 

relationship between hydraulic 

fracturing and drinking water. In 2011, 

EPA’s Office of Research and 

Development (ORD) published its Plan 

to Study the Potential Impacts of 

Hydraulic Fracturing on Drinking Water 

Resources. EPA has requested comment 

from individual ad hoc panel members 

on its Study of the Potential Impacts of 

Hydraulic Fracturing on Drinking Water 

Resources as well as plan future 

potential activities of the panel. The 

Progress Report describes the status of 

EPA’s ongoing research on the potential 

mstockstill on DSK4VPTVN1PROD with NOTICES

20638 Federal Register / Vol. 78, No. 66 / Friday, April 5, 2013 / Notices 

impacts of hydraulic fracturing on 

drinking water resources. 

On August 21, 2012, the SAB Staff 

Office requested public nominations of 

experts to serve on a Panel to advise the 

Agency on EPA’s ongoing research on 

the potential impacts of hydraulic 

fracturing on drinking water resources 

(77 FR 50505—50506). On November 

27, 2012, the SAB Staff Office posted a 

notice on the SAB Web site inviting 

public comments by December 19, 2012, 

on candidates for the Panel. Information 

about formation of the Panel can be 

found at http://yosemite.epa.gov/sab/

eba00436459/b436304ba804e3f885257

a5b00521b3b!OpenDocument&Table

Row=2.1#2. 

The purpose of the May 7–8, 2013, 

meeting is for individual members of 

the Panel to provide expert comments 

on charge questions associated with the 

research described in EPA’s Progress 

Report. The purpose of the May 16, 

2013, teleconference is to provide 

additional opportunity for members of 

the public to submit relevant oral 

statements on EPA documents for 

consideration by the Panel. 

Also, periodic opportunities for the 

public to provide additional input for 

consideration by the Panel will be 

provided after the May 7–8, 2013 public 

meeting and May 16, 2013 public 

teleconference call. 

Availability of Meeting Materials: The 

agenda and other materials in support of 

the meeting and teleconference call will 

be available on the SAB Web site at 

http://www.epa.gov/sab in advance of 

the meeting and teleconference call. 

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 the EPA. Members of the 

public can submit relevant comments 

for consideration by the Panel. Input 

from the public to the SAB will have the 

most impact if it provides specific 

scientific or technical information or 

analysis for the SAB to consider or if it 

relates to the clarity or accuracy of the 

technical information. Members of the 

public wishing to provide comment 

should contact the DFO directly. 

Oral Statements: In general, 

individuals or groups requesting an oral 

presentation at a public meeting will be 

limited to five minutes. Persons 

interested in providing oral statements 

at the May 7–8, 2013, meeting should 

contact Mr. Hanlon at the contact 

information provided above by April 30, 

2013. If there is insufficient time during 

the May 7–8, 2013 public meeting call 

to allow all scheduled public speakers 

to provide oral statements, those 

scheduled public speakers who could 

not provide oral statements during the 

May 7–8, 2013 public meeting will be 

provided opportunity to present their 

oral statements during a teleconference 

call scheduled to occur on May 16, 

2013. 

Written Statements: Written 

statements for the May 7–8, 2013, 

meeting and May 16, 2013, 

teleconference call should be received 

in the SAB Staff Office by April 30, 

2013, so that the information may be 

made available to the SAB for its 

consideration prior to this meeting and 

teleconference call. Written statements 

should be supplied to the DFO in the 

following formats: either an electronic 

copy (preferred), via email (acceptable 

file format: Adobe Acrobat PDF, MS 

Word, WordPerfect, MS PowerPoint, or 

Rich Text files in IBM–PC/Windows 98/ 

2000/XP format), or in hard copy. 

Submitters are asked to provide 

electronic versions of each document 

submitted without signatures, because 

the SAB Staff Office does not publish 

documents with signatures on its Web 

sites. Members of the public should be 

aware that their personal contact 

information, if included in any written 

comments, may be posted to the SAB 

Web site. Copyrighted material will not 

be posted without explicit permission of 

the copyright holder. 

Accessibility: For information on 

access or services for individuals with 

disabilities, please contact Mr. Hanlon, 

at the phone number or email address 

noted above, preferably at least ten days 

prior to the meeting and teleconference 

call, to give the EPA as much time as 

possible to process your request.
