Manage Pesticides of Concern. Pesticides that are identified as a concern following the evaluation must be managed. At the state or tribal level, a pesticide is actively managed when extra or focused activities are carried out to prevent or reduce contamination of water by a particular active ingredient so that it is prevented from reaching the water quality standard or other reference point, or brought below the reference point. Where appropriate, grantees are encouraged to consult with or coordinate prevention and protection of water resources with other agencies with responsibilities for water resource protection. The following examples of active management were identified by the EPA/State Workgroup that developed the national pesticide water quality measures in 2005. They are not meant to be inclusive and regions can negotiate other activities with states and tribes to manage pesticides of concern: • Applicator or user education, hands-on training, or public outreach on practices that minimize the amount of the pesticides of concern that enter water; • Water quality assessment to identify vulnerable water resources and conducting outreach to applicators and growers on locally-specific management practices that should be taken to protect water quality in these sensitive areas; • Promotion and adoption of voluntary BMPs judged to prevent or reduce contamination by a particular pesticide e.g., riparian buffer zones, filter strips, no-till cultivation; • Management control decisions based on spatially and temporally focused surveillance monitoring; • Targeted inspections and enforcement of existing water quality-related label restrictions and cancellation notices; • Designation as state or tribal “Restricted Use” due to water quality concerns; • Imposition of other use or label restrictions designed to reduce contamination of a pesticide; • Denial of state registration due to water quality concerns; • Activities specific to assessing and addressing CWA § 303(d) “impaired waters.” • Activities specific to assessing and addressing urban and agricultural watersheds that exceed USGS NAWQA benchmarks for pesticides. The schedule, priority and level of effort assigned to managing pesticides of concern should be negotiated in consideration of the resources available to the state or tribe and the relative priority of pesticide in water issues in relation to other pesticide issues the state or tribe is facing. However, OPP recommends that grantees and regions consider placing priority on managi...
Manage Pesticides of Concern. Over time, actively manage pesticides of concern beyond the label to reduce or prevent further contamination of local water resources.
