Supplemental Information for

Water Quality Standards Regulatory Revisions Final Rule

New or Updated CWA Section 304(a) Criteria Recommendations

Published since May 30, 2000

NOTE: The EPA’s final rule revision at § 131.20(a) requires that if states and authorized 

tribes choose not to adopt new or revised criteria during their triennial review for any 

parameters for which EPA has published new or updated criteria recommendations under 

CWA section 304(a), they must explain their decision when reporting the results of their 

triennial review to EPA under CWA section 303(c)(1) and 40 CFR 131.20(c).

When states and authorized tribes conduct their next triennial review, they must provide 

an explanation for why they did not adopt new or revised criteria for parameters for which 

EPA has published new or updated CWA section 304(a) criteria recommendations since 

May 30, 2000. During the triennial reviews that follow, states and authorized tribes must 

do the same for criteria for parameters for which EPA has published CWA section 304(a) 

criteria recommendations since the states’ or authorized tribes’ most recent triennial 

review.

This document provides a list of the new or updated CWA section 304(a) criteria 

recommendations that have been published since May 30, 2000. This document does not 

represent the entirety of CWA section 304(a) criteria recommendations. For a complete 

list, see: http://water.epa.gov/scitech/swguidance/standards/criteria/current/index.cfm.

*P/NP – Indicates either a Priority Pollutant (P) or a Non Priority Pollutant (NP). 

**Criteria Maximum Concentration and Criterion Continuous Concentration 

The Criteria Maximum Concentration (CMC) is an estimate of the highest concentration of a material 

in surface water to which an aquatic community can be exposed briefly without resulting in an 

unacceptable effect. The Criterion Continuous Concentration (CCC) is an estimate of the highest 

concentration of a material in surface water to which an aquatic community can be exposed 

indefinitely without resulting in an unacceptable effect. The CMC and CCC are just two of the six 

parts of an aquatic life criterion; the other four parts are the acute averaging period, chronic 

averaging period, acute frequency of allowed exceedence, and chronic frequency of allowed 

exceedence. Because CWA section 304(a) aquatic life criteria are national guidance, they are intended 

to be protective of the vast majority of the aquatic communities in the United States. 

A Freshwater and saltwater criteria for metals are expressed in terms of the dissolved metal in the 

water column. See "Office of Water Policy and Technical Guidance on Interpretation and 

Implementation of Aquatic Life Metals Criteria (PDF)," (49 pp, 3MB) October 1, 1993, by Martha G. 

Prothro, Acting Assistant Administrator for Water, available on NSCEP's web site and 40 CFR

131.36(b)(1). Conversion Factors applied in the table can be found in Appendix A to the PreambleConversion Factors for Dissolved Metals.

B The freshwater criterion for this metal is expressed as a function of hardness (mg/L) in the water 

column. The value given here corresponds to a hardness of 100 mg/L. Criteria values for other 

hardness may be calculated per the equation presented in the criteria document.

C For the saltwater copper criteria, when the concentration of dissolved organic carbon is elevated, 

copper is substantially less toxic and use of Water-Effect Ratios might be appropriate.

*P/NP – Indicates either a Priority Pollutant (P) or a Non Priority Pollutant (NP). 

A This chemical has a criterion for organoleptic (taste and order) effects. In some cases, the 

organoleptic criterion may be more stringent.

B This criterion was revised to reflect EPA's q1* or RfD as contained in the Integrated Risk 

Information System (IRIS) as of May 17, 2002. The fish tissue bioconcentration factor (BCF) is from 

the 1980 Ambient Water Quality Criteria document.

C This criterion is based on carcinogenicity of 10-6 risk. 

D EPA has issued a Maximum Contaminant Level (MCL) for this chemical under the Safe Drinking 

Water Act. In some cases, the MCL may be more stringent. For more information see EPA's National 

Primary Drinking Water Regulations.
