Federal Register / Vol. 72, No. 60 / Thursday, March 29, 2007 / Notices 14807 

Federal agencies will serve as technical 

advisors, and will provide background 

information and technical support to the 

stakeholder panel as needed. 

Composition of the stakeholder panel 

may vary somewhat by meeting, 

depending on which topics will be 

discussed. This notice is not a 

solicitation for stakeholder panel 

participants. 

EPA anticipates that the stakeholder 

panel will meet on several occasions 

over a 6–month period. The meetings 

will be open to the public, with 

opportunities for the public to make oral 

comments to the stakeholder panel. 

EPA will ask the stakeholder panel to 

consider two questions: 

1. How should the various nonFederal stocks of commodity-grade 

mercury be managed both in the short 

term and the long term? 

2. How do current and future supply 

and demand affect this determination 

for each of the various stocks? 

For more information, see the EPA 

background paper, entitled Options for 

Managing U.S. Non-Federal Supplies of 

Commodity-Grade Mercury. To access 

the background paper, see ADDRESSES. 

III. Issues for Public Comment 

EPA invites the public to send written 

comments on the same two questions 

addressed to the stakeholder panel: 

1. How should the various nonFederal stocks of commodity-grade 

mercury be managed both in the short 

term and the long term? 

2. How do current and future supply 

and demand affect this determination 

for each of the various stocks? 

EPA advises commenters to use the 

background paper as they prepare 

comments. The background paper is 

entitled Options for Managing U.S. NonFederal Supplies of Commodity-Grade 

Mercury. To access the background 

paper, see ADDRESSES. 

IV. How Can I Request to Participate in 

the Meeting? 

Persons interested in attending the 

public meeting are encouraged to preregister and state whether they intend to 

make an oral comment. Pre-registration 

assists in planning adequate seating and 

in securing access to the building. Oral 

comments should address the two 

questions in the charge to the 

stakeholder panel which are found in 

Unit II. To pre-register, provide your 

name, organization, telephone number, 

and the docket ID number EPA–HQ–

OPPT–2007–0148 to the technical 

person listed under FOR FURTHER

INFORMATION CONTACT. Pre-registration 

requests must be received on or before 

April 12, 2007. Do not submit any 

information in your pre-registration that 

is considered CBI. 

Oral comments will be scheduled in 

the order the requests are received by 

EPA. EPA may need to limit the length 

of oral comments to allow for 

participation by all parties. 

EPA requests that oral comments be 

included in the docket. Please follow 

the instructions under ADDRESSES.

SUPPLEMENTARY INFORMATION: 

I. Information About the Project/ 

Document 

This report describes the potential 

scope and magnitude of climate change 

impacts on the cost of meeting water 

quality based effluent limits at publicly 

owned treatment works (POTWs) 

discharging to rivers and streams in the 

Great Lakes Region (GLR). The report is 

a screening level analysis focusing on 

costs of meeting water quality based 

effluent limits for a single pollutant, 

biochemical oxygen demand at all 

POTWs in the region discharging to 

currently impaired stream reaches. 

POTWs discharge billions of gallons of 

effluent daily to receiving water bodies 

throughout the United States. One of the 

principal pollutants associated with 

POTW effluent is organic matter. 

Naturally, occurring microbial 

populations in receiving waters 

consume dissolved oxygen (DO) as they 

decompose organic matter. Low DO is a 

significant source of water quality 

impairment. Climate change in many 

parts of the country is expected to 

increase the proportion of rainfall

occurring in high-intensity events, 

resulting in increased stormwater 

runoff. At the same time, a shift towards 

more intense storms is expected to 

decrease infiltration and groundwater 

recharge, resulting in reduced low-flow 

periods between events. Increased air 

temperatures and evapotranspiration 

could also result in reduced streamflow 

between rainfall events. Reduced lowflow events in receiving waters could 

result in increased water quality 

impairment below POTWs due to 

reduced dilution of effluent.

comment period for the external review 

draft document. 

The public comment period and the 

external peer-review workshop are 

separate processes that provide 

opportunities for all interested parties to 

comment on the document. In addition 

to consideration by EPA, all public 

comments submitted in accordance with 

this notice will also be forwarded to 

ORISE for consideration by the external 

peer-review panel prior to the 

workshop.
