Registration Review Draft Risk Assessments for Linuron and Several Pyrethroids; Re-opening of Comment Period

In the Federal Register of November 29, 2016, EPA announced the availability of and solicited public comment on the registration review draft risk assessments for a number of pesticide chemicals, including several pyrethroid insecticides listed in Table 1 of Unit II. and the herbicide linuron listed in Table 2 of Unit II. This document re-opens the comment period on the ecological risk assessment for the pyrethroid chemicals for 60 days; and re-opens the comment period on the human health and ecological risk assessments for the chemical linuron for 30 days. EPA is re-opening these comment periods in response to a number of extension requests received from various stakeholders who have cited reasons including the difficulty of commenting due to the length, quantity, and complexity of the assessments for these particular chemicals, in addition to resource and time constraints.
