Court Rejects Most of NGOs’ ESA Pesticides Claims

The United States Court of Appeals rejected most of the environmentalist NGOs’ claims in the case Center for Biological Diversity v. EPA. The court provided the following summary of its lengthy decision (footnotes omitted”):

“The panel affirmed in part, and reversed in part, the district court’s dismissal of plaintiffs’ claims arising from their citizen suit alleging that the U.S. Environmental Protection Agency violated the Endangered Species Act (“ESA”) when it registered certain pesticide active ingredients and pesticide products without undertaking consultation with the National Marine Fisheries Service and the United States Fish and Wildlife Service (collectively “the Service”).

CRE Comments on EPA’s Atrazine ECO Risk Assessment

Trending: Track and Trace

CRE filed comments on EPA’s draft Ecological Risk Assessment for atrazine (“ERA”).  CRE’s comments included the following conclusion and recommended EPA actions:

There are no field data–no real-world data–supporting the ERA’s modeled effects. EPA should revise its ERA to be consistent with this fact.

If EPA still believes that some change in the current ecological assessment and regulation of atrazine may be necessary, then EPA should first take the following actions:

1) Validate the ERA models in accordance with the principles discussed above;

2) Develop field data supporting any changes proposed by EPA;


EPA Releases Guidance on a Voluntary Pilot Program to Reduce Animal Testing

On December 20, 2016, EPA published the following press release:

“EPA is announcing the start of a voluntary pilot program to evaluate the usefulness and acceptability of a mathematical tool that estimates the toxicological classification of a chemical, which is used in the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) and which is referred to as the GHS Mixtures Equation. This mathematical tool can be used as an alternative to acute animal oral and inhalation toxicity studies for pesticide formulations. EPA is now providing guidance on how pesticide companies can voluntarily submit data for the GHS Mixtures Equation Pilot Program.


CRE Comments at Glyphosate SAP

On December 14, 2016, the Center for Regulatory Effectiveness commented at EPA’s Science Advisory Panel reviewing EPA’s assessment of the carcinogenic potential of glyphosate. CRE’s comments agree with EPA’s conclusion that glyphosate is not likely to be carcinogenic to humans at doses relevant to human health risk assessment. Any contrary EPA conclusion would violate the Information Quality Act. Click here to read CRE’s oral comments at the SAP meeting.


EPA Reschedules Glyphosate SAP

EPA sent out the following notice:

“The Federal Insecticide, Fungicide, and Rodenticide Act Scientific Advisory Panel (SAP) will meet December 13-16, 2016, to consider and review a set of scientific issues being evaluated by the Environmental Protection Agency (EPA) regarding EPA’s evaluation of the carcinogenic potential of the herbicide glyphosate.  This is the meeting that was rescheduled from October 18-21, 2016.

EPA has published meeting materials in docket EPA-HQ-OPP-2016-0385 at www.regulations.gov, including a glyphosate issue paper with the Agency’s proposed classification that glyphosate is not likely to be carcinogenic to humans at doses relevant for human health risk assessment.
