Elevated levels of aluminum can affect some species ability to regulate ions and inhibit respiratory functions. Aquatic plants are generally less sensitive to aluminum than fish and other aquatic life. III. What are EPA’s updated recommended levels of aluminum in freshwater? Aluminum is found in most soils and rocks and is the third most abundant element and the most common metal in the earth’s crust. Aluminum can enter the water via natural processes, like weathering of rocks. Aluminum is also released to water by mining, industrial processes using aluminum, and waste water treated with alum, an aluminum compound. Aluminum is considered a The recommended level of aluminum in freshwater depends on a site’s water quality parameters. Studies have shown that three water chemistry parameters, pH, dissolved organic carbon (DOC), and hardness, can affect the toxicity of aluminum by affecting the bioavailability of aluminum in the water to aquatic species.

II. What is Aluminum and how does it affect aquatic life?

    Aluminum is found in most soils and rocks and is the third most 
abundant element and the most common metal in the earth's crust. 
Aluminum can enter the water via natural processes, like weathering of 
rocks. Aluminum is also released to water by mining, industrial 
processes using aluminum, and waste water treated with alum, an 
aluminum compound. Aluminum is considered a non-essential metal because 
fish and other aquatic life do not need it to function. Elevated levels 
of aluminum can affect some species ability to regulate ions and 
inhibit respiratory functions. Aquatic plants are generally less 
sensitive to aluminum than fish and other aquatic life.

III. What are EPA's updated recommended levels of aluminum in 
freshwater?

    The recommended level of aluminum in freshwater depends on a site's 
water quality parameters. Studies have shown that three water chemistry 
parameters, pH, dissolved organic carbon (DOC), and hardness, can 
affect the toxicity of aluminum by affecting the bioavailability of 
aluminum in the water to aquatic species. Unlike the fixed criteria 
values in EPA's 1988 criteria document, these updated draft criteria 
use a Multiple Linear Regression (MLR) model to normalize the data, and 
the resulting criteria are based on site pH, DOC, and hardness. This 
allows users to develop site-specific aluminum criteria for fresh 
waters that appropriately reflect water quality parameters. See Table 1 
for a comparison of EPA's currently recommended and updated draft 
criteria values.

IV. What are section 304(a) water quality criteria?

    Section 304(a) water quality criteria are recommendations developed 
by EPA under authority of section 304(a) of the Clean Water Act based 
on the latest scientific information which examines the effect of a 
particular constituent concentration on an aquatic species and/or human 
health.
    Section 304(a)(1) of the Clean Water Act directs the EPA to develop 
and publish and, from time to time, revise criteria for water quality 
accurately reflecting the latest scientific knowledge. Water quality 
criteria developed under section 304(a) are based solely on data and 
scientific judgments on the relationship between pollutant 
concentrations and environmental and human health effects. Section 
304(a) criteria do not reflect consideration of economic impacts or the 
technological feasibility of meeting pollutant concentrations in 
ambient water.
    Section 304(a) criteria provide guidance to states and authorized 
tribes in adopting water quality standards that ultimately provide a 
basis for controlling discharges of pollutants. The criteria also 
provide guidance that EPA considers when promulgating federal 
regulations under section 303(c) when such action is necessary. Under 
the Clean Water Act and its implementing regulations, states and 
authorized tribes are to adopt water quality criteria to protect 
designated uses (e.g., aquatic life, recreational use). EPA's water 
quality criteria recommendations are not regulations. Thus, EPA's 
recommended criteria do not constitute legally binding requirements. 
States and authorized tribes may adopt other scientifically defensible 
water quality criteria that differ from these recommendations. As part 
of the WQS

[[Page 35200]]

triennial review process defined in section 303(c)(1) of the CWA, the 
states and authorized tribes are responsible for maintaining and 
revising WQS. Standards consist of designated uses, water quality 
criteria to protect those uses, a policy for antidegradation, and may 
include general policies for application and implementation. Section 
303(c)(1) requires states and authorized tribes to review and modify, 
if appropriate, their WQS at least once every three years. States and 
authorized tribes must adopt water quality criteria that protect 
designated uses. Consistent with EPA's regulations at 40 CFR 131.11(a), 
protective criteria must be based on a sound scientific rationale and 
contain sufficient parameters or constituents to protect the designated 
uses. Criteria may be expressed in either narrative or numeric form. 
States and authorized tribes have four options when adopting water 
quality criteria for which EPA has published section 304(a) criteria. 
They may: (1) Establish numerical values based on recommended section 
304(a) criteria; (2) Adopt section 304(a) criteria modified to reflect 
site-specific conditions; (3) Adopt criteria derived using other 
scientifically defensible methods; or (4) Establish narrative criteria 
where numeric criteria cannot be established or to supplement numeric 
criteria (40 CFR 131.11(b)).

V. Solicitation of Scientific Views

    EPA is soliciting additional scientific views, data, and 
information regarding the science and technical approach used in the 
derivation of the draft criteria.
