SUPPLEMENTARY INFORMATION: 

Pharmaceuticals are being discovered in 

our Nation’s waters at very low 

concentrations. EPA has been studying 

unused pharmaceutical disposal 

practices at health care facilities, 

prompted by the concern that large 

amounts of pharmaceuticals are being 

flushed or disposed of down the drain, 

ultimately ending up in rivers, streams 

and coastal waters. 

The Agency has drafted a guidance 

document for health care facilities, 

which describes: 

• Techniques for reducing or 

avoiding pharmaceutical waste; 

• Practices for identifying and 

managing types of unused 

pharmaceuticals; and 

• Applicable disposal regulations. 

The guidance is targeted at hospitals, 

medical clinics, doctors’ offices, longterm care facilities and veterinary 

facilities. EPA expects that this 

document will help reduce the amount 

of pharmaceuticals that are discharged 

to water bodies. 

The document is available on EPA’s 

Web site at http://water.epa.gov/scitech/ 

wastetech/guide/ 

unusedpharms_index.cfm. 

EPA has visited many facilities and 

consulted with organizations in the 

health care industry, as well as federal, 

state and local government agencies. 

EPA continues to solicit 

recommendations from a wide range of 

stakeholders and welcomes comments 

on the draft document. We plan to 

publish a final version of the document 

in late 2010.

Housing Density Growth 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice of availability. 

SUMMARY: The U.S. Environmental 

Protection Agency (EPA) is announcing 

the availability of a final Geographic 

Information System (GIS) tool and final 

user’s guide titled, ‘‘ICLUS v1.3 User’s 

Manual: ArcGIS Tools and Datasets for 

Modeling U.S. Housing Density Growth’’ 

(EPA/600/R–09/143F). The tool and its 

documentation were prepared by the 

National Center for Environmental 

Assessment (NCEA) within EPA’s Office 

of Research and Development. The GIS 

tool can be used to modify land use 

scenarios for the conterminous United 

States. ICLUS stands for Integrated 

Climate and Land Use Scenarios, a 

project which is described in the 2009 

EPA Report, ‘‘Land-Use Scenarios: 

National-Scale Housing-Density 

Scenarios Consistent with Climate 

Change Storylines.’’ These scenarios are 

broadly consistent with global-scale, 

peer-reviewed storylines of population

growth and economic development, 

which are used by climate change 

modelers to develop projections of 

future climate. 

DATES: The GIS tool and documentation 

will be available on or about September 

8, 2010. 

ADDRESSES: ‘‘ICLUS v1.3 User’s Manual: 

ArcGIS Tools and Datasets for Modeling 

U.S. Housing Density Growth’’ and the 

geoprocessing tools will be available to 

download via an ftp site on the NCEA’s 

home page under the Recent Additions 

and Publications menus at http:// 

www.epa.gov/ncea. A limited number of 

paper copies of the User’s Manual are 

available from the Information 

Management Team, NCEA; telephone: 

703–347–8561; facsimile: 703–347– 

8691. If you are requesting a paper copy, 

please provide your name, your mailing 

address, and the final document title, 

‘‘ICLUS v1.3 User’s Manual: ArcGIS

SUPPLEMENTARY INFORMATION: 

I. Information About the GIS Tool and 

Document 

The GIS tool and its documentation, 

‘‘ICLUS v1.3 User’s Manual: ArcGIS 

Tools and Datasets for Modeling U.S. 

Housing Density Growth’’ enables users 

to run a spatially explicit allocation 

model with the population projections 

developed for the ICLUS project. Users 

can modify the spatial allocation of 

housing density across the landscape to 

customize scenarios of future 

development patterns. The data 

provided consist of five population 

scenarios by county for the 

conterminous U.S. and are available in 

5-year increments from 2000 to 2100. 

The population projections for each U.S. 

county drive the production of new 

housing units, which are allocated in 

response to the spatial pattern of 

previous growth (e.g., 1990 to 2000), 

transportation infrastructure, and other 

basic assumptions. The housing 

allocation model recomputes housing 

density in 5-year time steps from the 

year 2000 to 2100. 

The GIS tool allows users to: 

• Access the county-level ICLUS 

population projections; 

• Customize housing density patterns 

by altering household size and travel 

time assumptions; 

• Classify housing density into 

generalized categories; 

• Estimate future impervious surface 

based on a housing density; and 

• Summarize levels of 

imperviousness by housing density 

classes. 

In December 2009, the draft GIS tools 

and user’s guide were released for 

independent external review and a 

Federal Register notice, published 

December 8, 2009, announced the start 

of a public review and comment period. 

These final GIS tools and user’s guide 

address comments received from both 

the external peer review and the public.

Background: EPA’s Integrated Risk 

Information System (IRIS) is an 

electronic database containing 

descriptive and quantitative 

toxicological information on human 

health effects that may result from 

chronic exposure to various substances 

in the environment. This information 

supports human health risk assessments 

and includes hazard identification and 

dose-response data and derivations of 

oral reference doses (RfDs) and 

inhalation reference concentrations 

(RfCs) for noncancer effects and oral 

slope factors and oral and inhalation 

unit risks for cancer effects. IRIS is 

prepared and maintained by EPA’s 

National Center for Environmental 

Assessment (NCEA) within the Office of 

Research and Development (ORD). 

NCEA’s IRIS Program has developed a 

draft technical document entitled, 

Development of a Relative Potency 

Factor (RPF) Approach for Polycyclic 

Aromatic Hydrocarbon (PAH) Mixtures, 

for estimating cancer risk from exposure 

to PAH mixtures. ORD has requested 

that the Science Advisory Board (SAB) 

conduct a review of this draft document.
