Bergeson & Campbell, P.C.

The U.S. Environmental Protection Agency (EPA) has posted two prepublication Federal Register notices concerning its Endocrine Disruptor Screening Program (EDSP).  In the first notice, EPA announces the EDSP Tier 1 battery of assays and availability of test guidelines for conducting the assays included in the battery.  In the second notice, EPA announces the issuance of the initial EDSP screening orders and the schedule of issuance.  EPA expects both notices to be published in the Federal Register on October 21, 2009.  The notices are available at

According to the second notice, EPA intends to issue test orders for the first group of 67 chemicals between October 29, 2009, and February 26, 2010.  Screening data are due within two years of the date of the issuance of the order.  Order recipients must respond according to the schedules contained in the order they receive.  EPA states that persons other than order recipients who wish to submit “other scientifically relevant information related to one of the chemical-specific orders” should submit that information within 90 days of the order issuance date.  The notice includes the following order issuance schedule:
