Parties Who Requested that EPA Revoke All Tolerances and Cancel All Registrations for Chlorpyrifos, and Eight States, File New Petitions Challenging EPA’s 2019 Order Denying that Request, Seek Consolidation with the Existing Chlorpyrifos Case, and Oppose a Motion by EPA to Dismiss the Existing Case as Moot

On August 7, 2019, the League of United Latin American Citizens, Pesticide Action Network North America, Natural Resources Defense Council, and other petitioners (Petitioners) filed a new petition in the Ninth Circuit Court of Appeals seeking judicial review of United States Environmental Protection Agency (EPA) orders denying their request that EPA revoke all tolerances and cancel all registrations for chlorpyrifos.  On August 8, 2019, New York, California, Hawaii, Maryland, Vermont, Washington, Massachusetts, and the District of Columbia (States) also filed a new petition for judicial review concerning the refusal of EPA to ban chlorpyrifos.  The Petitioners and the States seek judicial review of the July 18, 2019, final order by EPA dismissing all objections to the initial decision by EPA to retain tolerances and registrations for chlorpyrifos, and of EPA’s March 29, 2017, order that initially denied a 2007 petition to revoke all tolerances and cancel all registrations for chlorpyrifos.

The Petitioners and the States also seek consolidation of their newly filed petitions for judicial review with currently pending chlorpyrifos litigation in LULAC, et al. v. Wheeler, et al.  As part of rehearing in the LULAC case, the Ninth Circuit vacated a prior decision that ordered EPA to cancel chlorpyrifos registrations, and instead issued a writ of mandamus requiring EPA to respond to objections to the 2017 denial order within 90 days.  EPA then issued the July 18, 2019, order denying all objections, along with a motion on July 19, 2019, to dismiss the LULAC case as moot.  EPA seeks dismissal of LULAC because it contends that the 2017 initial order was never itself reviewable, and EPA has now done everything that the writ of mandamus required. The Petitioners oppose the motion to dismiss because it would require the Court to take a position on a jurisdictional issue which they contend was not decided during rehearing.  The Petitioners and the States also argue that dismissal would be unnecessary and inefficient, requiring the challenging parties to reconstitute the record for review compiled in LULAC.

Petitioners also note that the Ninth Circuit retained jurisdiction when it issued mandamus in LULAC, and they request that their combined challenge to the EPA decision to retain the existing tolerances and registrations for chlorpyrifos be heard by the Court en banc as well.

Commentary

The latest petitions for judicial review of EPA’s 2019 decision to retain all tolerances and registrations for chlorpyrifos pending registration review were anticipated by all parties, and all parties agree that the procedural requisites for a judicial determination concerning the legality of EPA’s final decision to deny the 2007 administrative petition have now been satisfied.  The Petitioners and the States will likely argue that prior scientific determinations by EPA, including EPA analysis of epidemiology studies that purport to establish a link between exposure to chlorpyrifos and adverse neurodevelopmental effects in children, require that EPA proceed to revoke all tolerances and cancel all registrations for chlorpyrifos, while EPA will likely argue that difficult scientific issues concerning chlorpyrifos remain unresolved and should be addressed by EPA as part of the pending registration review for chlorpyrifos.

In addition to the dispute about combining the new petitions for review with the LULAC case, an interesting element of the latest filing by the Petitioners is that they attempt to bootstrap en banc review of the 2019 order in which EPA finally denied the administrative petition to revoke tolerances and cancel registrations for chlorpyrifos.  En banc review for an initial hearing (as opposed to en banc rehearing in a previously decided case) is allowed by the applicable appellate rules, but such review is disfavored and would be highly unusual.  Petitioners argue that it is warranted here because the en banc panel in the rehearing in the LULAC case reserved jurisdiction.  Given the motion by EPA to dismiss the LULAC case as moot, it can be presumed that EPA is likely to oppose this vicarious argument for en banc judicial review.   EPA can argue that the only reason the en banc panel retained jurisdiction was to assure that EPA would timely comply with the writ of mandamus that required EPA to rule on the objections within 90 days.
