            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)(l) 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

*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, 1 993, by Martha G.
Prothro, Acting Assistant Administrator for Water, available on NSCEP's web site and 40 CFR
1 31.36(b)(l). Conversion Factors applied in the table can be found in Appendix A to the Preamble-
Conversion 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 1 00 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.

BThis criterion was revised to reflect EPA's ql* or RfD as contained in the Integrated Risk
Information System (IRIS) as of May 1 7, 2002. The fish tissue bioconcentration factor (BCF) is from
the 1 980 Ambient Water Quality Criteria document.

C This criterion is based on carcinogenicity of 1 0 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.

EThis fish tissue residue criterion for methylmercury is based on a total fish consumption rate of
0.0175 kg/day.

F This criterion applies to total PCBs (e.g., the sum of all congener or all isomer or homolog or
Aroclor analyses).
