establishes standards for certain environmental
protection subjects that are more stringent than
federal law or regulations.
This bill would also require that in the absence
of federal law or regulations, agencies may not adopt a
new rule, or amend an existing rule, that establishes

BE IT ENACTED BY THE LEGISLATURE OF ALABAMA:
Section 1. (a) For purposes of this section, the
following terms have the following meanings:
(1) AGENCY. The term as defined in Section 41-22-3,
Code of Alabama 1975.
(2) BEST AVAILABLE SCIENCE. Science that:
a. Is reliable, unbiased, subject to independent
verification, and applies to the agency's rule;
b. Maximizes the quality, objectivity, relevance,
completeness, and integrity of information, including
statistical information; human, animal, and other relevant
scientific studies; and, if applicable, human health
risk-based assessments; and
c. Involves the use of scientifically defensible and
quality-assured supporting studies conducted in accordance
with generally accepted scientific or technical practices
utilizing data collected by generally accepted methods or best
available methods and that are:
1. Site-specific studies, including area-wide or
statewide studies;
2. Studies published in a refereed journal; or
3. External peer-reviewed studies contained in a
federal government report published for a purpose other than
development of a rule.
(3) GENERALLY ACCEPTED SCIENTIFIC OR TECHNICAL
PRACTICES. Scientific methods, principles, or protocols that:
a. Are broadly acknowledged and routinely applied by

a. Are broadly acknowledged and routinely applied by
the relevant scientific community;
b. Are consistent with refereed journal literature or
established technical standards; and
c. Have been tested for reliability and validity.
(4) MANIFEST BODILY HARM. A physical disease or injury
that is:
a. Presently existing and diagnosable;
b. Not based solely on the presence or detection of a
substance in the human body; and
c. Not based solely on an increased risk of disease.
(5) REFEREED JOURNAL. A publication that:
a. Uses an editorial board or critical review panel of
subject matter experts in the relevant scientific or technical
disciplines who critically and objectively assess the
methodology and analysis of submitted scientific studies in a
nonpartisan fashion and provides editorial services prior to
publication; and
b. Takes meaningful steps to avoid biases in the
publication's scientific review process.
(6) WEIGHT OF SCIENTIFIC EVIDENCE. An approach to
scientific evaluation in which each piece of relevant
information is considered based on its quality and relevance,
which, at a minimum, includes consideration of study design,
fitness for purpose, replicability, peer review, and
transparency and reliability of data; and the information is
transparently integrated with other relevant information to
inform the scientific evaluation prior to making a judgment
about the scientific evaluation.

about the scientific evaluation.
(b) An agency may not adopt a new rule or amend an
existing rule that establishes new or changes existing numeric
criteria or numeric limitations applicable to a chemical
substance, mixture, contaminant, pollutant, hazardous
substance, solid waste, hazardous constituent, or hazardous
waste that relates to drinking water, water pollution control,
hazardous substances, contaminated site remediation, air
quality, solid waste handling, or hazardous waste handling if
the new rule or amendment would result in criteria or
limitations that are more stringent or extensive in scope,
coverage, or effect than any federal law or regulation setting
a standard regarding the same or a substantially similar
topic.
(c) Notwithstanding subsection (b), if there is no
federal law or regulation establishing a standard regarding
the same or a substantially similar topic, an agency may not
adopt a new rule or amend an existing rule that establishes
numeric criteria or numeric limitations applicable to a
chemical substance, mixture, contaminant, pollutant, hazardous
substance, solid waste, hazardous constituent, or hazardous
waste that relates to drinking water, water pollution control,
hazardous substances, contaminated site remediation, air
quality, solid waste handling, or hazardous waste handling
unless, for each individual chemical substance, mixture,
contaminant, pollutant, hazardous substance, solid waste,
hazardous constituent, or hazardous waste to which the rule
applies, the scientific and technical information relied on to
support the standard established by the rule is based on the

support the standard established by the rule is based on the
best available science and the weight of scientific evidence.
(d)(1) For any rule adopted pursuant to subsection (c)
to protect human health, safety, or welfare, the best
available science and the weight of scientific evidence shall
establish a direct causal link between exposure at or above
the numeric criteria or numeric limitations provided by the
rule and manifest bodily harm in humans, based on generally
accepted scientific or technical practices.
(2) In the absence of data from voluntary scientific
studies on humans, best available science and the weight of
scientific evidence may be based on tests performed on
experimental animal species or human and animal cells
establishing a direct causal link, based on generally accepted
scientific or technical practices, between exposure at or
above the numeric criteria or numeric limitations provided by
the rule and manifest bodily harm in humans, provided that the
harm may be extrapolated to humans based on the best available
science and the weight of scientific evidence.
(e) No agency shall be required to use values from the
United States Environmental Protection Agency's Integrated
Risk Information System in the development of numeric water
quality criteria.
(f) This section does not apply to any of the
following:
(1) A rule that is required by federal law or
regulation, including a rule adopted to comply with, and in
furtherance of, federal agency authorization or primacy
requirements.
