Federal Register / Vol. 74, No. 160 / Thursday, August 20, 2009 / Notices 42069 

EPA requests that the public provide 

to EPA any water quality related data 

and information that may be relevant to 

the calculations for the 12 TMDLs. EPA 

will review all data and information 

submitted during the public comment 

period and revise the TMDLs where 

appropriate. EPA will then forward the 

TMDLs to the Louisiana Department of 

Environmental Quality (LDEQ). The 

LDEQ will incorporate the TMDLs into 

its current water quality management 

plan.

Clean Water Act Section 303(d): 

Availability of List Decisions 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice of availability. 

SUMMARY: This action announces the 

availability of EPA decisions identifying 

water quality limited segments and 

associated pollutants in Arizona to be 

listed pursuant to Clean Water Act 

section 303(d)(2), and requests public 

comment. Section 303(d)(2) requires 

that states submit and EPA approve or 

disapprove lists of waters for which 

existing technology-based pollution 

controls are not stringent enough to 

attain or maintain state water quality 

standards and for which total maximum 

daily loads (TMDLs) must be prepared. 

On July 31, 2009, EPA partially 

approved and partially disapproved 

Arizona’s 2006–2008 submittal. 

Specifically, EPA approved Arizona’s 

listing of 54 waters, associated 

pollutants, and associated priority 

rankings. EPA disapproved Arizona’s 

decisions not to list 23 water quality 

limited segments and associated 

pollutants, and additional pollutants for 

5 water bodies already listed by the 

State. EPA identified these additional 

water bodies and pollutants along with 

priority rankings for inclusion on the 

2006–2008 section 303(d) list. 

EPA is providing the public the 

opportunity to review its decisions to 

add waters and pollutants to Arizona 

2006–2008 section 303(d) list, as 

required by EPA’s Public Participation 

regulations. EPA will consider public 

comments in reaching its final decisions 

on the additional water bodies and 

pollutants identified for inclusion on 

Arizona’s final lists. 

DATES: Comments must be submitted to 

EPA on or before September 21, 2009. 

ADDRESSES: Comments on the proposed 

decisions should be sent to Susan 

Keydel, Water Division (WTR–2), U.S. 

Environmental Protection Agency 

Region IX, 75 Hawthorne Street, San 

Francisco, CA 94105, telephone (415) 

972–3106, facsimile (415) 947–3537, 

e-mail keydel.susan@epa.gov. Oral 

comments will not be considered. 

Copies of the proposed decisions 

concerning Arizona which explain the 

rationale for EPA’s decisions can be 

obtained at EPA Region 9’s Web site at 

http://www.epa.gov/region9/water/ 

tmdl/303d.html or by writing or calling 

Ms. Keydel at the above address. 

Underlying documentation comprising 

the record for these decisions is 

available for public inspection at the 

above address. 

FOR FURTHER INFORMATION CONTACT: 

Susan Keydel at (415) 972–3106 or 

keydel.susan@epa.gov. 

SUPPLEMENTARY INFORMATION: Section 

303(d) of the Clean Water Act (CWA) 

requires that each state identify those 

waters for which existing technologybased pollution controls are not 

stringent enough to attain or maintain 

state water quality standards. For those 

waters, states are required to establish 

TMDLs according to a priority ranking. 

EPA’s Water Quality Planning and 

Management regulations include 

requirements related to the 

implementation of section 303(d) of the 

CWA [40 CFR 130.7]. The regulations 

require states to identify water quality 

limited waters still requiring TMDLs 

every two years. The lists of waters still 

needing TMDLs must also include 

priority rankings and must identify the 

waters targeted for TMDL development 

during the next two years [40 CFR 

130.7]. 

Consistent with EPA’s regulations, 

Arizona submitted to EPA its listing 

decisions under section 303(d)(2), 

received on December 17, 2008. On July 

31, 2009, EPA approved Arizona’s 

listing of 54 waters and associated 

priority rankings. EPA disapproved 

Arizona’s decisions not to list 23 water 

quality limited segments and associated 

pollutants, and additional pollutants for 

5 water bodies already listed by the 

State. EPA identified these additional 

waters and pollutants along with 

priority rankings for inclusion on the 

2006–2008 section 303(d) list. EPA 

solicits public comment on its 

identification of additional waters and 

associated pollutants, and additional 

pollutants for waters already listed by 

the State, for inclusion on Arizona’s 

2006–2008 Section 303(d) list.

SUPPLEMENTARY INFORMATION: 

I. Summary of Information About the 

Integrated Risk Information System 

(IRIS) 

IRIS is a database that contains 

potential adverse human health effects 

information that may result from 

chronic (or lifetime) exposure to specific 

chemical substances found in the 

environment. The database (available on 

the Internet at http://www.epa.gov/iris) 

contains qualitative and quantitative 

health effects information for more than 

540 chemical substances that may be 

used to support the first two steps 

(hazard identification and doseresponse evaluation) of a risk 

assessment process. When supported by 

available data, the database provides 

oral reference doses (RfDs) and 

inhalation reference concentrations 

(RfCs) for chronic health effects, and 

oral slope factors and inhalation unit 

risks for carcinogenic effects. Combined 

with specific exposure information, 

government and private entities can use 

IRIS data to help characterize public 

health risks of chemical substances in a 

site-specific situation and thereby 

support risk management decisions 

designed to protect public health.
