What Is the Information Products Bulletin (IPB)?
The Information Products Bulletin (IPB) is a joint effort between the U.S. Environmental Protection Agency (EPA) and the Environmental Council of the States (ECOS) 
to inform stakeholders and the public about upcoming significant information products. EPA and the States are committed to ensuring that the significant information products we produce are accurate and useful, and that we clearly characterize the data incorporated into these products.
The IPB has been developed to:
- Notify interested parties about significant information products under development or major modification by EPA and some States; and
- Inform stakeholders and the public about opportunities to provide input regarding the development of some of these products.
Please Note: The IPB is not intended to be a compilation of the information products that have already been completed and released to the public by EPA or the States. Nor does the IPB include regulatory matters requiring publication in the Federal Register. The inclusion of a particular significant information product in the IPB, in and of itself, does not confer any special legal status on the product.
