Tight-fitting facepiece means a respiratory inlet covering that forms a complete seal with the face.
Air dried coating means a coating that is dried by the use of air or forced warm air at temperatures up to 1940F (900C).
Automotive windshield washer fluid means any liquid designed for use in a motor vehicle windshield washer system either as an antifreeze or for the purpose of cleaning, washing, or wetting the windshield. Automotive windshield washer fluid does not include fluids placed by the manufacturer in a new vehicle.
Polystyrene foam adhesive means an aerosol adhesive designed to bond polystyrene foam to substrates.
Hydraulic fracturing means the fracturing of underground rock formations, including shale and non-shale formations, by manmade fluid-driven techniques for the purpose of stimulating oil, natural gas, or other subsurface hydrocarbon production.
Sludge dryer means any enclosed thermal treatment device that is used to dehydrate sludge and that has a maximum total thermal input, excluding the heating value of the sludge itself, of 2,500 Btu/lb of sludge treated on a wet-weight basis.
Sewage sludge weight means the weight of sewage sludge, in dry U.S. tons, including admixtures such as liming materials or bulking agents. Monitoring frequencies for sewage sludge parameters are based on the reported sludge weight generated in a calendar year (use the most recent calendar year data when the NPDES permit is up for renewal).
Residual disinfectant concentration means the concentration of disinfectant measured in mg/L in a representative sample of water.
Polystyrene foam means blown polystyrene and expanded and
Nitrogen oxides means nitric oxide and nitrogen dioxide, expressed as nitrogen dioxide (NO2);
Diatomaceous earth filtration means a process resulting in substantial particulate removal in which a precoat cake of diatomaceous earth filter media is deposited on a support membrane (septum), and 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.
medium voltage means the set of nominal voltage levels that lie above low voltage and below high voltage in the range of 1 kV to 44 kV;
Bulk gasoline plant means a gasoline storage and distribution facility with an average daily throughput of 20,000 gallons (76,000 liters) of gasoline or less on a 30-day rolling average.
Riprap means small, broken stones or boulders placed compactly or irregularly on dykes or similar embankments for protection of earth surfaces against wave action or current;
Cathode ray tube or “CRT” means a vacuum tube, composed primarily of glass, which is the visual or video display component of an electronic device. A “used, intact CRT” means a CRT whose vacuum has not been released. A “used, broken CRT” means glass removed from its housing or casing whose vacuum has been released.
Geothermal fluid means water in any form at temperatures greater than 120
Cannabinoid extract means a substance obtained by separating cannabinoids from marijuana by:
explosive actuated fastening device means a tool that is activated by an explosive charge and that is used for driving bolts, nails and similar objects for the purpose of providing fixing;
Grab sample means an individual sample collected in less than 15 minutes in conjunction with an instantaneous flow measurement.
Oxides of nitrogen means the sum of the volume mixing ratio (ppbv) of nitrogen monoxide (nitric oxide) and nitrogen dioxide expressed in units of mass concentration of nitrogen dioxide (µg/m3);
Membrane filtration means a pressure or vacuum driven separation process in which particulate matter larger than 1 micrometer is rejected by an engineered barrier, primarily through a size-exclusion mechanism, and which has a measurable removal efficiency of a target organism that can be verified through the application of a direct integrity test. This definition includes the common membrane technologies of microfiltration, ultrafiltration, nanofiltration, and reverse osmosis.
Loop Concentrator/Multiplexer or "LCM" is the Network Element that does one or more of the following: aggregates lower bit rate or bandwidth signals to higher bit rate or bandwidth signals (multiplexing); disaggregates higher bit rate or bandwidth signals to lower bit rate or bandwidth signals (demultiplexing); aggregates a specified number of signals or channels to fewer channels (concentrating); performs signal conversion, including encoding of signals (e.g., analog to digital and digital to analog signal conversion); or in some instances performs electrical to optical (E/O) conversion. LCM includes DLC, and D4 channel banks and may be located in Remote Terminals or Central Offices.
Ultra Low Sulfur Diesel Fuel means diesel fuel that has a sulfur content of no more than fifteen parts per
Sewage sludge fee weight means the weight of sewage sludge, in dry U.S. tons, excluding admixtures such as liming materials or bulking agents. Annual sewage sludge fees, as per section 3745.11(Y) of the Ohio Revised Code, are based on the reported sludge fee weight for the most recent calendar year.
Gasohol means a blended fuel composed of gasoline and fuel grade ethanol.
Loose-fitting facepiece means a respiratory inlet covering that is designed to form a partial seal with the face.
