Safe Agriculture Production Act of 2017 This bill amends the Plant Protection Act to allow state, local, or tribal governments to use methyl bromide as a fumigant if: (1) the use is required to respond to an emergency concerning a significant economic loss of crops to pests or diseases, and (2) the Department of Agriculture (USDA) does not object to that use within a specified time period. The bill allows this use of methyl bromide during an emergency event regardless of whether the use is registered and included in the label approved for the product by the Environmental Protection Agency under Federal Insecticide, Fungicide, and Rodenticide Act. The bill limits the amount of methyl bromide that may be used per emergency event at a specific location to not more than 20 metric tons. The aggregate amount of methyl bromide used in the United States each year may not exceed the total amount authorized under the Montreal Protocol on Substances that Deplete the Ozone Layer. The bill gives USDA exclusive authority for determining which species are considered quarantine pests.
