**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.

**ICLUS v1.3 User’s Manual: ArcGIS Tools and Datasets for Modeling U.S.**  **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,

**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.

The SAB PAH Mixtures Review Panel held a public teleconference on June 8, 2010 and a public meeting on June 21– 23, 2010 to review EPA’s Development of a Relative Potency Factor (RPF) Approach for Polycyclic Aromatic Hydrocarbon (PAH) Mixtures [ see Federal Register notice dated May 18, 2010 ( 75 FR 27777–27778 )]. Materials from the June 8, 2010 teleconference and June 21–23, 2010 meeting are posted on the SAB Web site at http:// yosemite.epa.gov/sab/sabproduct.nsf/ fedrgstr
