# TABLE 30: Aquatic Life Water Quality Criteria for Toxic

Pollutants

Effective April 18, 2014

Aquatic Life Criteria Summary

The concentration for each compound listed in Table 3 0 is a criterion not to be exceeded in waters of

the state in order to protect aquatic life. The aquatic life criteria apply to waterbodies where the

protection of fish and aquatic life are the designated use s

. A ll values are expressed as micrograms per

liter (μg/L) . Compounds are listed in alphabetical order with the corresponding information: the

Chemical Abstract Service (CAS) number, whether there is a human health criterion for the pollutant

(i.e. “y”= yes, “n” = no), and the associated aquatic life freshwater and saltwater acute and chronic

criteria

. Italicized pollutants are not identified as priority pollutants by EPA

. Dashes in the table column

indicate that there is no aquatic life criterion.

Unless otherwise noted in the table below, t he acute criteri on is the Criterion Maximum

Concentration (CMC) applied as a one

- hour average concentration, and the chronic crit eri on is

the Criterion Continuous Concentration (CCC) applied as a 96

- hour (4 days) average

concentration. T he CMC and CCC criteria should not be exce eded more than once every three

years. Footnote A, associated with eleven pesticide pollutants in Table 30, describes the

exception to the frequency and duration of the toxics criteria stated in this paragraph.

### Endnote A: Alternate Frequency and Duration for Certain Pesticides

This criterion is based on EPA recommendations issued in 1980 that were derived using

guidelines that differed from EPA's 1985 Guidelines which update minimum data requirements

and derivation procedur es. The CMC may not be exceeded at any time and the CCC may not

be exceeded based on a 24

- hour average. The CMC may be applied using a one hour

averaging period not to be exceeded more than once every three years, if the CMC values

given in Table 30 are di vided by 2 to obtain a value that is more comparable to a CMC derived

using the 1985 Guidelines.

Endnote E: Equations for Hardness

- Dependent Freshwater Metals Criteria for Cadmium

Acute and Copper Acute and Chronic Criteria

The freshwater criterion for th is metal is expressed as total recoverable with two significant

figures, and is a function of hardness (mg/L) in the water column. Criteria values for hardness

are calculated using the following formulas (CMC refers to the acute criterion; CCC refers to th e

chronic criterion):

CMC = (exp(m A 

### *[ln(hardness)] + b A 

### ))

CCC = (exp(m C 

### *[ln(hardness)] + b C 

### ))

Endnote F: Equations for Hardness

- Dependent Freshwater Metals Criteria and

Conversion Factor Table

The freshwater criterion for this metal is expressed as dissolved with two significant figures, and

is a function of hardness (mg/L) in the water column. Criteria values for hardness are calculated

using the following formulas (CMC refers to the acute criterion; CCC refers to the chronic

criterion):

CMC = (exp(m A 

### *[ln(hardness)] + b A

### Endnote A: Alternate Frequency and Duration for Certain Pesticides 

## Expanded Endnotes A, E, F

### This criterion is based on EPA recommendations issued in 1980 that were derived using

guidelines that differed from EPA's 1985 Guidelines which update minimum data requirements

and derivation procedures. The CM C may not be exceeded at any time and the CCC may not

be exceeded based on a 24

- hour average. The CMC may be applied using a one hour

averaging period not to be exceeded more than once every three years, if the CMC values

given in Table 30 are divided by 2 to obtain a value that is more comparable to a CMC derived

using the 1985 Guidelines.

Endnote E: Equations for Hardness

- Dependent Freshwater Metals Criteria for Cadmium

Acute and Copper Acute and Chronic Criteria

The freshwater criterion for this metal i s expressed as total recoverable with two significant

figures, and is a function of hardness (mg/L) in the water column. Criteria values for hardness

are calculated using the following formulas (CMC refers to the acute criterion; CCC refers to the

chronic criterion):

CMC = (exp(m A 

### *[ln(hardness)] + b A 

### ))

CCC = (exp(m C 

### *[ln(hardness)] + b C 

### ))

Endnote F: Equations for Hardness

- Dependent Freshwater Metals Criteria and

Conversion Factor Table

The freshwater criterion for this metal is expressed as dissolved with two significant figures, and

is a function of hardness (mg/L) in the water column. Criteria values for hardness are calculated

using the following formulas (CMC refers to the acute criterion; CCC refers to the chronic

criterion):

CMC = (exp(m A 

### *[ln(hardness)] + b A 

### ))*CF

CCC = (exp(m C 

### *[ln(hardness)] + b C 

### ))*CF

“CF” is the conversion factor used for converting a metal criterion expressed as the total

recoverable fraction in the water column to a criterion expressed as the dissolved fraction in

the water column.

criteria. For metals that are not hardness

silver (chronic)), or are saltwater criteria, the criterion value associated with the metal in Table

# TABLE 4 0 : Human Health Water Quality Criteria for Toxic Pollutants

Effective April 18, 2014

Human Health Criteria Summary

The concentration for each pollutant listed in Table 40 was derived to protect Oregonians from potential

adverse health impacts associated with long

- term exposure to toxic substances associated with consumption

of fish, shellfish, and water. The “organism only” criteria are established to protect fish and shellfish

consumption and apply to waters of the state designated for fishing. The “water + organism” criteria are

established to protect the consum ption of drinking water, fish, and shellfish, and apply where both fishing and

domestic water supply (public and private) are designated uses. All criteria are expressed as micrograms per

liter (μg/L), unless otherwise noted. Pollutants are listed in alpha betical order. Additional information includes

the Chemical Abstract Service (CAS) number, whether the criterion is based on carcinogenic effects (can

cause cancer in humans), and whether there is an aquatic life criterion for the pollutant (i.e. “y”= yes, “n” = no).

All the human health criteria were calculated using a fish consumption rate of 175 grams per day unless

otherwise noted. A fish consumption rate of 175 grams per day is approximately equal to 23 8

- ounce fish

meals per month. For pollutants cate gorized as carcinogens, values represent a cancer risk of one additional

case of cancer in one million people (i.e. 10

- 6 

### ), unless otherwise noted. All metals criteria are for total metal

concentration, unless otherwise noted. Italicized pollutants represen t non

- priority pollutants. The human health

criteria revisions established by OAR 340

- 041

- 0033 and shown in Table 40 do not become applicable for

purposes of ORS chapter 468B or the federal Clean Water Act until approved by EPA pursuant to 40 CFR

131.21 (4 /27/2000).

I The human health criterion for methoxychlor is the same as originally published in the 1976 EPA Red Book which predates the

1980 methodology and did not utilize the fish ingestion BCF approach. This same criterion value was also published in the 1986

EPA Gold Book. Human health risks are primarily from drinking water, therefore no “organism only” crit erion was developed.

Th e “water + organism” criterion is based on the Maximum Contaminant Level (MCL) established under the Safe Drinking Water

Act
