--------------------------------------------------------------------------------------------------------------------------------------------------------
a. Criteria revised to reflect current agency q b. The criteria refers to the inorganic form only.
c. Criteria in the matrix based on carcinogenicity (10−6 risk).
For a risk level of 10−5, move the decimal point in the matrix value
one place to the right.
d. Criteria Maximum Concentration (CMC) = the highest concentration of a
pollutant to which aquatic life can be exposed for a short period of time
(1-hour average) without deleterious effects. Criteria Continuous Concentration
(CCC) = the highest concentration of a pollutant to which aquatic life can be
exposed for an extended period of time (4 days) without deleterious effects.
μg/L = micrograms per liter.
e. Freshwater aquatic life criteria for these metals are expressed as a
function of total hardness (mg/L as CaCO f. Freshwater aquatic life criteria for pentachlorophenol are expressed as a
function of pH, and are calculated as follows. Values displayed above in the
matrix correspond to a pH of 7.8. CMC
= exp(1.005(pH)−4.830)
CCC
= exp(1.005(pH)−5.290) g. Aquatic life criteria for these compounds were issued in 1980 utilizing
the 1980 Guidelines for criteria development. The acute values shown are final
acute values (FAV) which by the 1980 Guidelines are instantaneous values as
contrasted with a CMC which is a one-hour average.
h. These totals simply sum the criteria in each column. For aquatic life,
there are 31 priority toxic pollutants with some type of freshwater or
saltwater, acute or chronic criteria. For human health, there are 85 priority
toxic pollutants with either "water + fish" or "fish only" criteria. Note that
these totals count chromium as one pollutant even though EPA has developed
criteria based on two valence states. In the matrix, EPA has assigned numbers 5a
and 5b to the criteria for chromium to reflect the fact that the list of 126
priority toxic pollutants includes only a single listing for chromium.
i. If the CCC for total mercury exceeds 0.012 μg/l more than once in a 3-year
period in the ambient water, the edible portion of aquatic species of concern
must be analyzed to determine whether the concentration of methyl mercury
exceeds the FDA action level (1.0 mg/kg). If the FDA action level is exceeded,
the State must notify the appropriate EPA Regional Administrator, initiate a
revision of its mercury criterion in its water quality standards so as to
protect designated uses, and take other appropriate action such as issuance of a
fish consumption advisory for the affected area.
j. No criteria for protection of human health from consumption of aquatic
organisms (excluding water) was presented in the 1980 criteria document or in
the 1986 Quality Criteria for Water. Nevertheless, sufficient information was
presented in the 1980 document to allow a calculation of a criterion, even
though the results of such a calculation were not shown in the document.
k. The criterion for asbestos is the MCL (56 FR 3526, January 30, 1991).
l. [Reserved: This letter not used as a footnote.]
m. Criteria for these metals are expressed as a function of the water effect
ratio, WER, as defined in 40 CFR 131.36(c). CMC
= column B1 or C1 value × WER
CCC
= column B2 or C2 value × WER n. EPA is not promulgating human health criteria for this contaminant.
However, permit authorities should address this contaminant in NPDES permit
actions using the State's existing narrative criteria for toxics.
o. [Reserved: This letter not used as a footnote.]
p. Criterion expressed as total recoverable.
q. This criterion applies to total PCBs (e.g., the sum of all congener
or isomer or homolog or Aroclor analyses).
1. This chart lists all of EPA's priority toxic pollutants whether or not
criteria recommendations are available. Blank spaces indicate the absence of
criteria recommendations. Because of variations in chemical nomenclature
systems, this listing of toxic pollutants does not duplicate the listing in
Appendix A of 40 CFR Part 423. EPA has added the Chemical Abstracts Service
(CAS) registry numbers, which provide a unique identification for each chemical.
2. The following chemicals have organoleptic based criteria recommendations
that are not included on this chart (for reasons which are discussed in the
preamble): copper, zinc, chlorobenzene, 2-chlorophenol, 2,4-dichlorophenol,
acenaphthene, 2,4-dimethylphenol, 3-methyl-4-chlorophenol,
hexachlorocyclopentadiene, pentachlorophenol, phenol.
3. For purposes of this rulemaking, freshwater criteria and saltwater
criteria apply as specified in 40 CFR 131.36(c). Note to paragraph (b)(1): On April 14, 1995, the Environmental
Protection Agency issued a stay of certain criteria in paragraph (b)(1) of this
section as follows: the criteria in columns B and C for arsenic, cadmium,
chromium (VI), copper, lead, nickel, silver, and zinc; the criteria in B1 and C1
for mercury; the criteria in column B for chromium (III); and the criteria in
column C for selenium. The stay remains in effect until further notice.
(2) Factors for Calculating Hardness-Dependent, Freshwater Metals Criteria CMC=WER exp { m CCC=WER exp { m Final CMC and CCC values should be rounded to two significant figures. (c) Applicability. (1) The criteria in paragraph (b) of this section
apply to the States' designated uses cited in paragraph (d) of this section and
supersede any criteria adopted by the State, except when State regulations
contain criteria which are more stringent for a particular use in which case the
State's criteria will continue to apply.
(2) The criteria established in this section are subject to the State's
general rules of applicability in the same way and to the same extent as are the
other numeric toxics criteria when applied to the same use classifications
including mixing zones, and low flow values below which numeric standards can be
exceeded in flowing fresh waters.
(i) For all waters with mixing zone regulations or implementation procedures,
the criteria apply at the appropriate locations within or at the boundary of the
mixing zones; otherwise the criteria apply throughout the waterbody including at
the end of any discharge pipe, canal or other discharge point.
(ii) A State shall not use a low flow value below which numeric standards can
be exceeded that is less stringent than the following for waters suitable for
the establishment of low flow return frequencies (i.e., streams and rivers): Where: CMC -- criteria maximum concentration -- the water quality criteria to
protect against acute effects in aquatic life and is the highest instream
concentration of a priority toxic pollutant consisting of a one-hour average not
to be exceeded more than once every three years on the average;
CCC -- criteria continuous concentration -- the water quality criteria to
protect against chronic effects in aquatic life is the highest instream
concentration of a priority toxic pollutant consisting of a 4-day average not to
be exceeded more than once every three years on the average;
1 Q 10 is the lowest one day flow with an average recurrence frequency of
once in 10 years determined hydrologically;
1 B 3 is biologically based and indicates an allowable exceedence of once
every 3 years. It is determined by EPA's computerized method (DFLOW model);
7 Q 10 is the lowest average 7 consecutive day low flow with an average
recurrence frequency of once in 10 years determined hydrologically;
4 B 3 is biologically based and indicates an allowable exceedence for 4
consecutive days once every 3 years. It is determined by EPA's computerized
method (DFLOW model);
30 Q 5 is the lowest average 30 consecutive day low flow with an average
recurrence frequency of once in 5 years determined hydrologically; and the
harmonic mean flow is a long term mean flow value calculated by dividing the
number of daily flows analyzed by the sum of the reciprocals of those daily
flows. (iii) If a State does not have such a low flow value for numeric standards
compliance, then none shall apply and the criteria included in paragraph (d) of
this section herein apply at all flows.
(3) The aquatic life criteria in the matrix in paragraph (b) of this section
apply as follows:
(i) For waters in which the salinity is equal to or less than 1 part per
thousand 95% or more of the time, the applicable criteria are the freshwater
criteria in Column B;
(ii) For waters in which the salinity is equal to or greater than 10 parts
per thousand 95% or more of the time, the applicable criteria are the saltwater
criteria in Column C; and
(iii) For waters in which the salinity is between 1 and 10 parts per thousand
as defined in paragraphs (c)(3) (i) and (ii) of this section, the applicable
criteria are the more stringent of the freshwater or saltwater criteria.
However, the Regional Administrator may approve the use of the alternative
freshwater or saltwater criteria if scientifically defensible information and
data demonstrate that on a site-specific basis the biology of the waterbody is
dominated by freshwater aquatic life and that freshwater criteria are more
appropriate; or conversely, the biology of the waterbody is dominated by
saltwater aquatic life and that saltwater criteria are more appropriate.
(4) Application of metals criteria. (i) For purposes of calculating
freshwater aquatic life criteria for metals from the equations in paragraph
(b)(2) of this section, the minimum hardness allowed for use in those equations
shall not be less than 25 mg/l, as calcium carbonate, even if the actual ambient
hardness is less than 25 mg/l as calcium carbonate. The maximum hardness value
for use in those equations shall not exceed 400 mg/l as calcium carbonate, even
if the actual ambient hardness is greater than 400 mg/l as calcium carbonate.
The same provisions apply for calculating the metals criteria for the
comparisons provided for in paragraph (c)(3)(iii) of this section.
(ii) The hardness values used shall be consistent with the design discharge
conditions established in paragraph (c)(2) of this section for flows and mixing
zones.
(iii) Except where otherwise noted, the criteria for metals (compounds #2,
#4-# 11, and #13, in paragraph (b) of this section) are expressed as dissolved
metal. For purposes of calculating aquatic life criteria for metals from the
equations in footnote m. in the criteria matrix in paragraph (b)(1) of this
section and the equations in paragraphs (b)(2) of this section, the water-effect
ratio is computed as a specific pollutant's acute or chronic toxicity values
measured in water from the site covered by the standard, divided by the
respective acute or chronic toxicity value in laboratory dilution water.
(d) Criteria for Specific Jurisdictions -- (1) Rhode Island, EPA
