### Dear 

### Dr. Reiss: At the Iast 

### meeting 

### (March 5,2002)between

### representative

### from Syngenta 

### Crop Protection and 

### USEPA, 

### I promised to copies 

### ofother technical articles and papers on 

### aerosolreleases. These were references that 

### EPA had reviewed before 

### deciding that the 

### USDOE aerosol data might be a better 

### basis for 

### addressing the 

### TPQ issues

### regarding paraquat dichloride. 

### Enclosed are copies 

### of the references listed 

### on the attachment, except 

### where noted 

### (one is a 

### book and one 

### is a very large bound report). 

### I apologize for 

### sending these so Iate. 

### Sincerely,
