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.
Pressure means relative pressure versus atmospheric pressure, unless otherwise stated.
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)."
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.
Operating pressure means the pressure at which the parts of an irrigation system are designed by the manufacturer to operate.
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.
Tank means an enclosed space which is formed by the permanent structure of a ship and which is designed for the carriage of liquid in bulk.
Working pressure means the settled pressure of a compressed gas at a reference temperature of 15 °C in a full pressure receptacle;
Pressure vessel means a vessel that may be used for containing, storing, distributing, transferring, distilling, processing or otherwise handling any gas, vapour or liquid under pressure greater than the atmospheric pressure and includes any pipeline fitting or other equipment attached thereto or used in connection therewith; and
Intake means “Sanctioned Intake”.
Low water pressure means water pressure below the regulatory reference level which is the minimum pressure when demand on the system is not abnormal.
Density means the permitted number of dwelling units per
PAD means a Preauthorized Debit.
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.
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.
Runoff coefficient means the fraction of total rainfall that will appear at the conveyance as runoff.
Positive pressure respirator means a respirator in which the pressure inside the respiratory inlet covering exceeds the ambient air pressure outside the respirator.
Diameter means the diameter of the stem of a tree measured outside the bark at a specified point of measurement.
Sensor means any measurement device that is not part of the vehicle itself but installed to determine parameters other than the concentration of gaseous and particle pollutants and the exhaust mass flow.
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;
Nitrogen oxides means nitric oxide and nitrogen dioxide, expressed as nitrogen dioxide (NO2);
Gasohol means a blended fuel composed of gasoline and fuel grade ethanol.
Attachment point means a point on the network at which network assets are connected to assets owned by another person.
Biodiesel means a fuel composed of mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats, and, in accordance with standards specified by the American society for testing and materials, designated B100, and meeting the requirements of D-6751, as approved by the department of agriculture.
Tanks has the meaning set forth in Section 4.12(b).
Container means any portable device in which a material is stored, transported, treated, disposed of, or otherwise handled.
