​​Buffers Imposed by the U.S. District Court Order

Reinstated Streamside No-Spray Buffer Zones – New Information available from EPA as of 8/27/2014

“EPA reinstates no-spray buffer zones in California, Oregon and Washington to Protect salmon as a result of final settlement agreement for northwest center for alternatives to pesticides v. EPA”.

As of August 15, 2014, EPA reinstated streamside no-spray buffer zones to protect endangered or threatened Pacific salmon and steelhead in California, Oregon and Washington. This action is directed by a stipulated injunction (agreed to by the parties) that settles litigation brought against EPA by the Northwest Center for Alternatives to Pesticides and others in U.S. District Court in Washington State.  On August 15, 2014, the U.S. District Court for the Western District of Washington entered the stipulated injunction, reinstating the streamside no-spray buffer zones that were originally established in prior litigation; Washington Toxics Coalition (WTC) v. EPA.  The reinstated buffers are part of the final court order; however, they will not be included as labeling requirements under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).

No Spray buffer zones will be imposed for the following pesticides in waters that support salmon:

  • carbaryl
  • chlorpyrifos
  • diazinon
  • malathion
  • methomyl

The no-spray buffer zones, 20 yards (60 feet) for ground pesticide applications and 100 yards (300 feet) for aerial pesticide applications, are effective from August 15, 2014.  The no-spray buffer zone restrictions will remain in place until EPA implements any necessary protections for Pacific salmon and steelhead based on reinstated consultations with the National Marine Fisheries Services.  

To view the no-spray buffer zones go to EPA’s Salmon Mapper.  The interactive map will be updated no later than September 30, 2014, to include the current list of chemicals subject to the restrictions, enhanced spatial resolution, and the most recent geospatial data depicting stream reaches where the buffer zones apply.

Under the settlement agreement, there are three use exemptions carried over from the WTC case:

Public health vector control administered by public entities,

National Marine Fisheries Services authorized programs

Use of carbaryl under a Washington state-issued 24(c) registration for oyster beds in the estuarine mudflats of Willipa Bay and Grays Harbor.

In addition to the five pesticides being addressed by the stipulated injunction, buffers remain in effect for seven active ingredients that were included in the original WTC case, pending final biological opinions from the National Marine Fisheries Services.  These active ingredients are:

  • 1, 3-D
  • Bromoxynil
  • Diflubenzuron
  • Fenbutatin-oxide
  • Prometryn
  • Propargite
  • Racemic metholachlor
