An ERD (Entity Relationship Diagram) is a graphical representation of the data in rest within a system (e.g. a business, an organization, an application) that is subject to analysis.
The U.S. EPA established the Reference Dose (RfD) Work Group to address these concerns. In preparing this report, the RfD Work Group has drawn on traditional report on risk assessment (NRC, 1983), to more fully articulate the use of noncancer, nonmutagenic experimental data in reaching regulatory decisions about the significance of exposures to chemicals.
Participants in the RFS2 use the EPA Moderated Transaction System (EMTS) to submit transactions. EMTS incorporates features that help establish a well-functioning and transparent market for RINs. The EMTS data flow supports the reporting of all RIN transactions including the generation, separation, purchase and sale, and retirement of RINs.
