### RISK ASSESSMENTS FOR R EG ISTRA TI ON REV IEW As stated in the PWP, no data gaps (anticipated data needs) for 3-MCH have been identified. The most recent comprehens i ve risk assessment for 3-MCH was completed on March 9. 1998. in support of the first biochemical registration of 3-MCH, which occurred on June 25. 1999 (U.S. EPA, 1998). A risk assessment was also completed on Apri I 17
. 1978, in suppo rt of the first Experim e nt a l Use Permit (EU P) fo r 3

- MCF J, which was approved on A u g u s t 27 , 1 984 (U
. S. E P A , 1978 ). Because there are no data gaps for 3-MCH, a nd no add ition al inf ormation ha s been received on this biochemical since it was first registered, the Agency does not anticipate the need to conduct a new risk assessment during registration review. 

### T IM ELINE EPA has created the fo ll owing es tim a ted timeline for th e comp let ion of the 3-MCH reg i strat io n review in Table I. below. This projected timeline has not changed since the PWP.
