In the same vein, major EPA scientific reports such as health advisories, health assessment documents, criteria documents, and Risk Assessment Forum reports should also be cited in IRIS files, and we understand that this will occur in the future. Checks of the files for individual chemicals indicated that IRIS currently lacks citations to some key EPA reports on specific chemicals.

EPA either has or is developing other computerized lists of chemicals, but the planning and coordination among these efforts could be improved. EPA should consider what computerized chemical lists are needed, and, more broadly, how modern computer and telecommunications technology can assist in the processes of risk assessment and risk management for the thousands of chemicals that are of interest to EPA.

As you correctly state, IRIS is an important risk information resource both for the Agency, and for other organizations concerned with the potential health impacts of toxic chemicals in the environment. Because the summary risk information on, to date, 397 chemicals represents authoritative EPA consensus positions on the adverse health effects of these chemicals, the Agency is aware of its obligation to the user community to provide system oversight and quality assurance.

Updated monthly, it is used by EPA to provide high quality, timely scientific and technical information to Agency scientists, and promote Agency-wide coordination and consistency of risk assessments. Because IRIS, containing authoritative consensus EPA positions on chemical-specific potential adverse health effects, is used extensively both inside and outside the Agency, we recognize the need to maintain, and improve, the quality of the system, its access and delivery systems, and sufficient oversight.

These regulatory action sections provide information, including applicable Federal Register citations, for the Clean Air Act, Safe Drinking Water Act, Clean Water Act, Federal Insecticide, Rodenticide and Fungicide Act, Toxic Substances Control Act, Resource Conservation and Recovery Act and the Superfund Reauthorization Act. Because this regulatory information is subject to change, we are aware that this section needs to be carefully reexamined to insure that it is up-to-date and complete.

From page 589... ...
In 1986, IRIS was a new Agency resource tool containing both qualitative and quantitative risk assessment information. The EMAIL delivery system, by design, obliged users to look at the whole chemical file, not just selected small sections, thus providing a wider chemical profile.

From page 590... ...
6. List Coordination - The Agency recently took a major step forward in coordinating and cross-referencing regulatory and regulation-like lists, by approving development of a pointer system that will contain references to all chemicals and other pollutants regulated by EPA and to all the lists on which each chemical or pollutant occurs.
