2 INTRODUCTION

This is the Environmental Protection Agency’s (E PA or the Agency) Final Work Plan (FWP) for the registration review of kaolin. This work plan addresses public comments received concerning the Preliminary Work Plan (PWP), which was posted in the ka olin registration review docket (EPA-HQ-OPP-2014-0107). Kaolin is currently registered in one manufacturing use product and five end products for use as an insecticide (bro ad spectrum), fungicide (against powdery mildew) and plant growth regulator (for protec tion from heat stress and sun damage).

The Agency is implementing the registration revi ew program pursuant to Section 3(g) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), and will review each registered pesticide every 15 years to determine whether it continues to meet th e FIFRA standard for registration. Changes in science, public policy, and pesticide use practices occur over time. The registration review program is intended to make su re that, as the ability to assess risk evolves and as policies and practices change, al l registered pesticides continue to meet the statutory standard. The public phase of registration review begins wh en the initial docket is opened for each case. Information on this program is provided on the Agency’s website. 1

The FWP begins with any updates since the PWP wa s issued. Next is a summary of substantive comments received during the public comment peri od for the PWP concerning anticipated data needs, expected risk assessments, or the estimated timeline identified in the PWP, and a summary of the Agency’s responses to those comme nts. This section is followed by registration review planned data needs, risk assessments expected to be conducted, and the projected registration review timeline for kaolin. Las tly, there is a discu ssion of next steps.

UPDATES SINCE THE PWP WAS ISSUED

There are no additional updates on kao lin since the issuance of the PWP.

SUMMARY OF COMMENTS AND AGENCY RESPONSES

During the 60-day public comment period on th e kaolin PWP, which opened on March 28, 2014, and closed on May 27, 2014, the Agency did not receive any comments c oncerning this case.

PLANNED DATA NEEDS

The planned data needs have not changed fr om what was included in the kaolin PWP.

RISK ASSESSMENTS FOR REGISTRATION REVIEW

As stated in the PWP, no data ga ps (anticipated data needs) for kaolin have been identified. The most recent comprehensive risk assessment for kaolin was completed October 31, 1997, in support of the first biochemical registration of kaolin, which occu rred on March 17, 1998. Because there are no data gaps and no additiona l information has been received by the Agency

need to conduct a new risk asse ssment during registration review.

TIMELINE

EPA has created the following estimated timeline for the completion of the kaolin registration review in Table 1, below. This projected timeline has not changed since the PWP.
