{"abstract":"This regulation establishes time-limited tolerances for combined residues of imazapic-ammonium, (+)-2-[4,5-dihydro-4-methyl-4- (1-methylethyl)-5-oxo-1H-imidazol-2- yl]-5-methyl-3-pyridinecarboxylic acid, applied as its ammonium salt and its metabolite (+)-2-[4,5- dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H-imidazol-2-yl]-5- hydromethyl-3- pyridinecarboxylic acid both free and conjugated in or on grass forage at 30 ppm; grass hay at 15 ppm; milk, fat, meat, meat byproducts (except kidney) of cattle, goats, hogs, horses, and sheep at 0.10 ppm; kidney of cattle, goats, hogs, horses, and sheep at 1 ppm. This action is in response to EPA's granting of emergency exemptions under section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act authorizing use of the pesticide on pasture/rangeland and land in the Conservation Reserve Program. This regulation establishes a maximum permissible level for residues of imazapic-ammonium and its metabolite in these food commodities. The tolerances will expire and are revoked on December 31, 2001.","action":"Final rule.","agencies":[{"raw_name":"ENVIRONMENTAL PROTECTION AGENCY","name":"Environmental Protection Agency","id":145,"url":"https://www.federalregister.gov/agencies/environmental-protection-agency","json_url":"https://www.federalregister.gov/api/v1/agencies/145","parent_id":null,"slug":"environmental-protection-agency"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/1999/10/06/99-25842.html","cfr_references":[{"chapter":null,"citation_url":null,"part":180,"title":40}],"citation":"64 FR 54218","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This regulation is effective October 6, 1999.
