Tare Weight means the weight of an empty shipping container, excluding all materials used for wrapping, cushioning, banding, waterproofing, packaging, blocking and bracing articles within the exterior container.
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;
Operating pressure means the pressure at which the parts of an irrigation system are designed by the manufacturer to operate.
Pressure means relative pressure versus atmospheric pressure, unless otherwise stated.
design pressure means the maximum pressure that a pressure vessel or plant is designed to withstand safety when operating normally;
CO2 means carbon dioxide.
Engine degreaser means a cleaning product designed to remove grease, grime, oil and other contaminants from the external surfaces of engines and other mechanical parts.
Psia means pounds per square inch absolute.
High-temperature coating means a high performance coating labeled and formulated for application to substrates exposed continuously or intermittently to temperatures above 204oC (400oF).
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).
Vapor tight means equipment that allows no loss of vapors. Compliance with vapor-tight requirements can be determined by checking to ensure that the concentration at a potential leak source is not equal to or greater than 100 percent of the lower explosive limit (LEL) when measured with a combustible gas detector, calibrated with propane, at a distance of 1 inch (2.54 cm) from the source.
Carbon dioxide or “CO2” means the most common of the six primary greenhouse gases, consisting on a molecular level of a single carbon atom and two oxygen atoms.
True vapor pressure means the equilibrium partial pressure exerted by a petroleum liquid as determined in accordance with methods described in American Petroleum Institute (API) Bulletin 2517, Evaporation Loss from External Floating Roof Tanks, 1980. The API procedure may not be applicable to some high viscosity or high pour crudes. Available estimates of true vapor pressure may be used in special cases such as these.
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.
Hydrozone means a portion of the landscaped area having plants with similar water needs and rooting depth. A hydrozone may be irrigated or non-irrigated.
Nitrogen oxides means nitric oxide and nitrogen dioxide, expressed as nitrogen dioxide (NO2);
medium voltage means the set of nominal voltage levels that lie above low voltage and below high voltage in the range of 1 kV < Un 44 kV. [SANS 1019]
Uppermost aquifer means the geologic formation nearest the natural ground surface that is an aquifer, as well as lower aquifers that are hydraulically interconnected with this aquifer within the facility's property boundary.
Gasification means the substoichiometric oxidation or steam reformation of a substance to produce a gaseous mixture containing two or more of the following: (i) oxides of carbon; (ii) methane; and (iii) hydrogen;
Btu means British thermal unit.
Invasive plant species means species of plants not historically found in California that spread outside cultivated areas and can damage environmental or economic resources. Invasive species may be regulated by county agricultural agencies as noxious species. Lists of invasive plants are maintained at the California Invasive Plant Inventory and USDA invasive and noxious weeds database.
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)."
Ambient air means that portion of the atmosphere, external to buildings, to which the general public has access.
Blend means seed consisting of more than one variety of a kind, each in excess of five percent by weight of the whole.
Cubic foot of gas means the amount of gas required to fill a cubic foot of space when the gas is at an absolute pressure of fourteen and seventy-three hundredths (14.73) pounds per square inch at a temperature of sixty (60) degrees Fahrenheit.
Low water pressure means water pressure below the regulatory reference level which is the minimum pressure when demand on the system is not abnormal.
