Atmosphere means the air that envelops or surrounds the earth and includes all space outside of buildings, stacks or exterior ducts.
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.
Vegetation means trees, shrubs, nursery stock and other vegetation and includes the limbs or growth of any Vegetation.
Sediment means solid material, mineral or organic, that is in suspension, is being transported, or has been moved from its site of origin by air, water or gravity as a product of erosion.
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.
Reid vapor pressure means the vapor pressure of crude oil or other volatile petroleum products at 100 degrees Fahrenheit as determined by the latest edition of ASTM D6377 (RVPE): Standard Test Method for Determination of Vapor Pressure of Crude Oil.
Nitrogen oxides means nitric oxide and nitrogen dioxide, expressed as nitrogen dioxide (NO2);
Weatherization means building insulation (for attic, exterior walls and crawl space), siding to improve energy efficiency, replacement storm windows, replacement storm doors, replacement windows and replacement doors, and is considered a major system for rehabilitation.
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.
Inclement Weather means any weather condition that delays the scheduled arrival or departure of a Common Carrier.
Perfluoroalkyl and polyfluoroalkyl substances or “PFAS” means a class of fluorinated organic chemicals containing at least one fully fluorinated carbon atom.
Biomass means the biodegradable fraction of products, waste and residues from biological origin from agriculture (including vegetal and animal substances), forestry and related industries including fisheries and aquaculture, as well as the biodegradable fraction of industrial and municipal waste;
Irritant means any substance, other than a corrosive, that on
Anaerobic digestion ’ means a controlled process involving microbial decomposition of organic matter in the absence of oxygen ;
polygamous marriage means any marriage to which paragraph 5 applies;
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.
High global warming potential hydrofluorocarbons means any hydrofluorocarbons in a particular end use for which EPA’s Significant New Alternatives Policy (SNAP) program has identified other acceptable alternatives that have lower global warming potential. The SNAP list of alternatives is found at 40 CFR Part 82 subpart G with supplemental tables of alternatives available at (http://www.epa.gov/snap/).
Gasohol means a blended fuel composed of gasoline and fuel grade ethanol.
Flocculation means a process to enhance agglomeration or collection of smaller floc particles into larger, more easily settleable particles through gentle stirring by hydraulic or mechanical means.
CO2 means carbon dioxide.
Electrostatic spray means a method of applying a spray coating in which opposite electric charges are applied to the substrate and the coating. The coating is attracted to the substrate by the electrostatic potential between them.
Vapor pressure as herein used means Vapor Pressure at 100° Fahrenheit as determined by ASTM Method D-323-90, "Standard Method of Test for Vapor Pressure of Petroleum Products (Reid Method)."
Erosion means the detachment and movement of soil or rock fragments by water, wind, ice, or gravity.
Sexual penetration means vaginal intercourse, cunnilingus, fellatio, or anal intercourse between persons or insertion of the hand, finger, or object into the anus or vagina either by the actor or upon the actor's instruction. The depth of insertion shall not be relevant to the question of commission of the crime;
Anadromous fish means any species of fish which ascends rivers or streams from the sea for breeding purposes (e.g. Alewife, Salmon, Shad).
Degradation means a decrease in the useful life of the right-of-way caused by excavation in or disturbance of the right-of-way, resulting in the need to reconstruct such right-of-way earlier than would be required if the excavation or disturbance did not occur.
