Hi Brian Here’s the phenol calculation That 

### you sent 

## me for

### phenol As you can 

### see Bob calculated the criteria forwater organisms as follows 

## AWQC RfD x 

### RSC x 

# BW DI FCR x

# BCF x 

### 1000 

## ugmg However the correct formula is 

## AWQC RfD x 

### RSC x 

# BW x 

### 1000 

## ugmg DI 

### FCR x 

## BCR

I can see 

### where he might 

### have misinterpreted the reference 

### he used An additional parenthesis might 

### have helped in the expression of the equation in that reference Nevertheless the units just don’t 

### work out the 

## way it 

### was calculated 

### and the value is higher than it 

### would be if calculated correctly Best regards
Ellen

Hi 

## Mark I’m working 

### on the approval letter for acrolein and phenol in state 

### waters Using the 

### EPA methodologies 

### and Maine’s fish consumption rate of 32.4 

# gmday I 

### was able to calculate 

## human health criteria for acrolein that agreed with Maine’s 

### adopted revisions to 3.9 

# ug L for consumption of water 

### organisms and 5.0 for consumption of organisms

## only I 

### was also able to calculate the 

## human health criteria for phenol for consumption of organisms only that agreed with Maine’s adopted revision to 462,963 

## ugL However I 

### was not able to derive Maine’s adopted revision of the phenol criteria for consumption of

### water organisms to 10,514 

## ug

# L Using the following criteria derivation equation for

### Ambient Water Quality Criteria 

# AWQC AWQC RfD x RSC x 

# BWDI FI x 

# BAF see parameter definitions 

### and values 

## below
leads to a criteria of 10,267 

## ugL Please let 

## meknow if 

### you have 

## made any other assumptions regarding the parameters below or any other revision to the 

### methodology to account forthe difference Thanks
