Natural uranium means uranium with the naturally occurring distribution of uranium isotopes, which is approximately 0.711 weight percent uranium-235, and the remainder by weight essentially uranium-238.
Natural attenuation means a variety of physical, chemical or biological processes that, under favorable conditions, act without human intervention to reduce the mass, toxicity, mobility, volume, or concentration of hazardous substances in the environment. These in situ processes include: Natural biodegradation; dispersion; dilution; sorption; volatilization; and chemical or biological stabilization, transformation, or destruction of hazardous substances. See WAC 173- 340-370(7) for a description of the expected role of natural attenuation in site cleanup. A cleanup action that includes natural attenuation and conforms to the expectation in WAC 173- 340-370(7) can be considered an active remedial measure.
Diatomaceous earth filtration means a process resulting in substantial particulate removal in which (1) a precoat cake of diatomaceous earth filter media is deposited on a support membrane (septum), and (2) while the water is filtered by passing through the cake on the septum, additional filter media known as body feed is continuously added to the feed water to maintain the permeability of the filter cake.

Corrosion inhibitor means a substance capable of reducing the corrosivity of water toward metal plumbing materials, especially lead and copper, by forming a protective film on the interior surface of those materials.
Genetic resources means genetic material of actual or potential value;
Acute toxicity means concurrent and delayed adverse effects that result from an acute exposure and occur within any short observation period, which begins when the exposure begins, may extend beyond the exposure period, and usually does not constitute a substantial portion of the life span of the organism.
coronavirus means severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2);
Hydroelectric energy means water used as the sole source of energy to produce electricity.
Anaerobic digester means a liquid manure storage area that is constructed with the intent to capture and combust gas emissions resulting from the digestion of waste by microbes in anaerobic conditions. An anaerobic digester is a LMSA and is required to comply with all requirements applicable to LMSAs. Requirements specific to anaerobic digesters will be noted when applicable.
