Upgrades to Endangered Species Web Tool: Bulletins Live! Two
EPA is releasing Bulletins Live! Two, an upgraded version of Bulletins Live!, a web-based map application used to access geographically-specific threatened and endangered species protection Bulletins. This system is an important tool for pesticide users since it makes it easier to find pesticide use limitations for specific areas. Go to www.epa.gov/oppfead1/endanger/bulletins.htm to view the new application. Please note, if you are using Internet Explorer and have accessed Bulletins Live! in the past, you will need to clear your history or set your browser to check for newer versions of stored pages.
Bulletins generated by the application contain enforceable, geographically-specific pesticide use limitations that are necessary to ensure using a pesticide will not harm a threatened or endangered species or their critical habitat designated under the Endangered Species Act. A reference to Bulletins on a pesticide label ensures that the Bulletin’s pesticide use limitations are enforceable under the Federal Insecticide, Fungicide, and Rodenticide Act.
Bulletins Live! Two has several new features, including
- an interactive map;
- different base maps (satellite, street, geographic, etc.) to help users determine if specific pesticide use limitations apply in areas where the pesticide is intended for use; advanced
- searches for active ingredient, product (by name or registration number), location (state, county, specific address); and
- an enhanced system to receive public comments on draft Bulletins.
The new Bulletins Live! Two application is intended to replace Bulletins Live! and includes all of the current pesticide limitations captured in Bulletins Live! including 113 county Bulletins for 10 states for the protection of 14 threatened and endangered species.
Updated Salmon Mapper for Protecting Endangered and Threatened Salmon in the PNW and California
EPA is releasing an updated Salmon Mapper. The interactive map includes enhanced spatial resolution and the most recent geospatial data depicting salmon-supporting stream reaches where no-spray buffer zones apply in California, Oregon and Washington State for 12 pesticides that are subject either to the original 2004 injunction in Washington Toxics Coalition (WTC) v. EPA or the August 15, 2014, stipulated injunction in Northwest Center for Alternatives to Pesticides (NCAP) v. EPA.
The pesticides included in the NCAP v. EPA stipulated injunction are carbaryl, chlorpyrifos, diazinon, malathion and methomyl. The pesticides that remain subject to the original WTC v. EPA injunctive relief order are 1,3-dichloropropene, bromoxynil, diflubenzuron, fenbutatin oxide, metolachlor, prometryn and propargite.
These buffer zones will remain in place for carbaryl, chlorpyrifos, diazinon, malathion, and methomyl until EPA implements any necessary protections for Pacific salmon and steelhead based on reinitiated consultations with the National Marine Fisheries Services. Buffer zones for the remaining seven chemicals included in the WTC vs. EPA will remain in place until final Biological Opinions are completed. To view the no-spray buffer zones go to the Salmon Mapper.

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
EPA is reinstating streamside no-spray buffer zones to protect endangered or threatened Pacific salmon and steelhead in California, Oregon and Washington State. No-spray buffer zones will be imposed for the pesticides carbaryl, chlorpyrifos, diazinon, malathion and methomyl in waters that support salmon. These buffer zones will remain in place until EPA implements any necessary protections for Pacific salmon and steelhead based on reinitiated consultations with the National Marine Fisheries Services.
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 v. EPA. The reinstated buffers are part of the final court order; however, they will not be included as labeling requirements under Federal Insecticide, Fungicide, and Rodenticide Act.

EPA Introduces New Graphic to Help Consumers Make Informed Choices about Insect Repellents
The EPA today unveiled a new graphic that will be available to appear on insect repellent product labels. The graphic will show consumers how many hours a product will repel mosquitoes and ticks when used as directed.
The EPA’s new graphic will do for bug repellents what SPF labeling did for sunscreens. This new graphic will help parents, hikers and the general public better protect themselves and their families from serious health threats caused by mosquitoes and ticks that carry debilitating diseases. Incidence of these diseases is on the rise. The CDC estimates that there are nearly 300,000 cases of Lyme disease in the United States each year. Effective insect repellents can protect against serious mosquito- and tick-borne diseases.
The EPA is accepting applications from manufacturers that wish to add the graphic to their repellent product labels. The public could see the graphic on products early next year.
EPA is Advancing Pollinator Science and Sharing Useful Information with Growers and Beekeepers
At the request of beekeepers and growers alike, the agency has posted the Residual Time to 25% Bee Mortality (RT25) Data online. Bees may be susceptible to harm from direct exposure to pesticides sprayed on flowering plants, but pesticide residues generally decrease in toxicity as the spray dries and time passes. Farmers and beekeepers can use EPA's RT25 data to gauge the amount of time after application that a particular pesticide product remains toxic enough under real-world conditions to kill 25 percent of bees that are exposed to residues on treated plant surfaces. Some have used this information to select pesticide products with shorter periods in which the chemicals remain active and can affect bees.
Web-Distributed Labeling (WDL) for Pesticide Products
EPA is announcing the availability of PR Notice 2014-1 which presents the Agency's guidance on optional participation in WDL. The notice is intended to improve existing labeling by allowing users to download the portions of the pesticide labeling specific to their intended state and site of use.
Seed Treatment Resources Available
The American Seed Trade Assoc. and CropLife America have produced the "Guide to Seed Treatment Stewardship" to increase awareness among seed treatment applicators and growers about safe stewardship practices.
Consideration of Spray Drift in EPA's Pesticide Risk Assessment:
Notice of Availability and Request for Comment
EPA is announcing the availability of two draft guidance documents for public comment. These documents describe how off-site spray drift will be evaluated for ecological and human health risk assessments for pesticides. Once final, these guidance documents will be posted on EPA’s Web site, to ensure consistent risk assessment practices and provide transparency for pesticide registrants and other interested stakeholders. Comments must be received on or before March 31, 2014.
Submit your comments, identified by docket identification (ID)

WSDA Releases Criteria for Designating Pesticides Under I-502/I-692
WSDA has added a web page(http://agr.wa.gov/pestfert/pesticides/pesticideuseonmarijuana.aspx) to assist growers authorized by I-502 or I-692 who choose to use pesticides for the production of marijuana in Washington. The page contains links to the relevant regulatory agencies and to the WSDA criteria for designating pesticide use on marijuana. A searchable list of these pesticides is available from the WSU Pesticide information Center Online (PICOL) database. Tutorials for using PICOL are available on YouTube.
