EPA’s New Chemicals Program conducts a premanufacture screening program for new microorganisms under section 5 of TSCA.  EPA considers intergeneric microorganisms to be those formed from organisms in different genera or those formed with synthetic DNA not from the same genus. In 1997, EPA published regulations that fully implement its premanufacture program for microorganisms under TSCA section 5.

In March 2020, EPA finalized a rule to add two strains of microorganisms to the list of microorganisms eligible for an exemption from certain reporting requirements under TSCA. Manufacturers of new intergenetic Trichoderma reesei (strain QM6a) and Bacillus amyloliquefaciens (subspecies amyloliquefaciens)  may now be eligible to undergo a streamlined review process under TSCA's new chemicals review program with reduced TSCA fees. Read the final rule.
