As used in this part 10:
(1)Air quality related value (AQRV) means a feature or property of a class I
federal area other than visibility that the state of Colorado finds may be affected by
air pollution. General categories of air quality related values include odor, flora,
fauna, soil, water, geologic features, and cultural resources.
(2)Air quality related value baseline data means research data based on
site-specific measurements and samplings of air quality related values within a
class I federal area needed to substantiate a determination of whether or not a
particular observation is within the range of naturally occurring changes or
fluctuations.
(3)Best available retrofit technology means a control strategy for
addressing emissions of a stationary source developed on a

(2) Air quality related value baseline data means research data based on

class I federal area needed to substantiate a determination of whether or not a
particular observation is within the range of naturally occurring changes or
fluctuations.
(3) Best available retrofit technology means a control strategy for
addressing emissions of a stationary source developed on a case-by-case basis
after taking into consideration the costs of compliance, the energy and nonair
quality environmental impacts of compliance, any existing pollution control
technology in use at the source, the remaining useful life of the source, and the
degree of improvement in the air quality related value that may reasonably be
anticipated to result from the use of such technology.
(4) Peer review means a review of scientific or technical information by a
balanced objective panel of experienced scientists qualified to review the subject
matter involved in verifying the existence of or attributing the cause of an AQRV
impairment.
(5) Reasonably available control measure means a control strategy for
addressing emissions of a nonstationary source developed on a case-by-case basis
after taking into consideration the options available to achieve emission reductions
that a particular source or source category is capable of meeting as appropriate to
an air quality related value if such steps may be feasibly and practicably taken
considering technical and economic constraints.
(6) Significant impairment of an air quality related value means a
measurable change in an air quality related value that is outside the probability of
natural variability, that is caused by human activities, and that is causing a
significant adverse effect to flora, fauna, soil, geologic features, cultural resources,
or a beneficial use of water recognized under Colorado law.
