Monthly update to new chemicals cases under review.

TSCA Environmental Release Application (TERA) for Modified Escherichia coli

TERA submitted by University of North Carolina and given tracking designation of R-01-0001. The microorganism will be introduced into potential sources of fecal contamination to determine if the bacteria can be detected downstream from the release points.

TSCA Environmental Release Application (TERA) for Modified Pseudomonas Fluorescens

TERA submitted by Micro Systems Technologies, LLC and given the tracking designations of R-02-0001. The microorganism has been genetically modified to contain a bioluminescent gene that is activated upon metabolism of naphthalene and/or methyl salicylate.

TSCA Environmental Release Application (TERA) for Pseudomonas fluorescens strains HK44 and 5RL

TERAs submitted by the University of Tennessee and Micro Systems Technologies, LLC and given the tracking designation of R-04-01 and R-04-02. The strain will be tested to examine its ability to detect and monitor naphthalene and methyl salicylate.

Two TSCA Environmental Release Applications (TERAs) for Bradyrhizobium japonicum (B. japonicum)

TERAs pertaining to field trials of two mutant strains (Bj 5019 and TN 119(12)) of Bradyrhizobium japonicum (B. japonicum), a common soil bacterium which is used as a commercial seed inoculant.

Reduced Residue Chemistry Data Requirements for Seed-Treatment Uses

EPA is publishing new guidance, including a tiered approach to help manufacturers and EPA determine when the number of field trials can be reduced to register seed treatment uses.
