improve the practices associated with 

the development, evaluation, and 

application of models for environmental 

decision making. Furthermore, by 

providing access to its tools and 

methods, EPA increases transparency 

and can improve the public’s 

understanding of how science is used to 

make environmental decisions. 

While the Models Guidance does not 

impose legally binding requirements on 

EPA or the public, it provides 

recommendations on the principles of 

good modeling practice, stressing the 

importance of model quality, 

documentation, and transparency with 

the aim of helping to determine when 

and how a model can be used to inform 

a decision. 

ADDRESSES: The Models Guidance is 

available electronically through the 

CREM Web site: http://www.epa.gov/ 

crem. A limited number of paper copies 

will be available from EPA’s National 

Service Center for Environmental 

Publications (NSCEP), P.O. Box 42419, 

Cincinnati, OH 45242; telephone 1– 

800–490–9198 or 513–489–8190; 

facsimile: 301–604–3408; e-mail: 

NSCEP@bps-lmit.com. Please provide 

your name, mailing address, title, and 

EPA number (as given above) of the 

requested publication.

SUPPLEMENTARY INFORMATION: To 

achieve its mission of protecting human 

health and safeguarding the natural 

environment, the U.S. Environmental 

Protection Agency (EPA) often employs 

mathematical models to study 

environmental systems and processes. 

These modeling analyses often provide 

input for the development of regulatory 

decisions. EPA established the Council 

for Regulatory Environmental Modeling 

(CREM) in 2000 in an effort to improve 

the quality, consistency and 

transparency of EPA models. In 2003, 

the EPA Administrator directed the 

CREM to provide guidance for the 

development, assessment, and use of 

environmental models and to develop a 

publicly-accessible inventory of EPA’s 

most frequently used models. The 

Models Guidance and Models KBase 

were developed in close collaboration 

with members of the CREM, who 

represent EPA’s program and regional 

offices. This document represents the 

consensus view among EPA offices. The 

Models Guidance was also evaluated 

and approved by the EPA’s Science 

Policy Council, the Agency’s forum for 

senior level policy deliberation and 

coordination on significant science 

issues. 

Both the Models Guidance and the 

Models KBase were issued in draft form 

in January 2004. In addition to internal 

review, the CREM products have 

undergone an external review process 

through EPA’s Science Advisory Board 

(the report may be found at http:// 

www.epa.gov/sab/panels/ 

cremgacpanel.html). The CREM also 

commissioned the National Academy of 

Science’s (NAS) National Research 

Council to assess evolving scientific and 

technical issues related to the selection 

and use of computational and statistical 

models in decision making processes at 

EPA. The NRC report, entitled ‘‘Models 

of Environmental Regulatory Decision 

Making,’’ was released in 2007 and 

provides advice on the management, 

evaluation, and use of models at the 

EPA. The report may be found at 

http://www.nap.edu/ 

catalog.php?record_id=11972. 

A revised draft of the Models 

Guidance, which built on the 

recommendations of the Science 

Advisory Board review panel and the 

NRC report, was issued for public 

comment in August 2008.
