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.
Finished water means the water that is introduced into the distribution system of a public water system and is intended for distribution and consumption without further treatment, except as treatment necessary to maintain water quality in the distribution system (e.g., booster disinfection, addition of corrosion control chemicals).
Backpressure means a pressure (caused by a pump, elevated tank or piping, boiler, or other means) on the consumer's side of the service connection that is greater than the pressure provided by the public water system and which may cause backflow.
Water Surface Elevation (WSE means the height, in relation to mean sea level, of floods of various magnitudes and frequencies in the floodplains of coastal or riverine areas.
Pressure vessel means containers for the containment of pressure, either internal or external. This pressure may be obtained from an external source or by the application of heat from a direct or indirect source, or any combination thereof.
Maximum Concentration Level Assessment means the Maximum Concentration Level Assessment for the purposes of a Basic Comprehensive Certificate of Approval, described in the Basic Comprehensive User Guide, prepared by a Toxicologist using currently available toxicological information, that demonstrates that the concentration at any Point of Impingement for a Compound of Concern that does not have a Ministry Point of Impingement Limit is not likely to cause an adverse effect as defined by the EPA. The concentration at Point of Impingement for a Compound of Concern must be calculated in accordance with O. Reg. 419/05.
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.
Ultra Low Sulfur Diesel Fuel means diesel fuel that has a sulfur content of no more than fifteen parts per
Negative pressure respirator (tight fitting) means a respirator in which the air pressure inside the facepiece is negative during inhalation with respect to the ambient air pressure outside the respirator.
Working pressure means the maximum pressure to which a component is designed to be subjected to and which is the basis for determining the strength of the component under consideration. For CNG cylinder, the settled pressure of 20 MPa at a uniform temperature of 15 C. For LNG tank, the pressure of the LNG tank primary relief valve setting.
Base Capacity Demand Resource Price Decrement means, for the 2018/2019 and 2019/2020 Delivery Years, a difference between the clearing price for Base Capacity Demand Resources and Base Capacity Energy Efficiency Resources and the clearing price for Base Capacity Resources and Capacity Performance Resources, representing the cost to procure additional Base Capacity Resources or Capacity Performance Resources out of merit order when the Base Capacity Demand Resource Constraint is binding.
DNS test Means one non-‐recursive DNS query sent to a particular “IP address” (via UDP or TCP). If DNSSEC is offered in the queried DNS zone, for a query to be considered answered, the signatures must be positively verified against a corresponding DS record published in the parent zone or, if the parent is not signed, against a statically configured Trust Anchor. The answer to the query must contain the corresponding information from the Registry System, otherwise the query will be considered unanswered. A query with a “DNS resolution RTT” 5 times higher than the corresponding SLR, will be considered unanswered. The possible results to a DNS test are: a number in milliseconds corresponding to the “DNS resolution RTT” or, undefined/unanswered.
Low water pressure means water pressure below the regulatory reference level which is the minimum pressure when demand on the system is not abnormal.
Base Capacity Resource Price Decrement means, for the 2018/2019 and 2019/2020 Delivery Years, a difference between the clearing price for Base Capacity Resources and the clearing price for Capacity Performance Resources, representing the cost to procure additional Capacity Performance Resources out of merit order when the Base Capacity Resource Constraint is binding.
Total resource cost test or "TRC test" means a standard that is met if, for an investment in energy efficiency or demand-response measures, the benefit-cost ratio is greater than one. The benefit-cost ratio is the ratio of the net present value of the total benefits of the program to the net present value of the total costs as calculated over the lifetime of the measures. A total resource cost test compares the sum of avoided electric utility costs, representing the benefits that accrue to the system and the participant in the delivery of those efficiency measures, as well as other quantifiable societal benefits, including avoided natural gas utility costs, to the sum of all incremental costs of end-use measures that are implemented due to the program (including both utility and participant contributions), plus costs to administer, deliver, and evaluate each demand-side program, to quantify the net savings obtained by substituting the demand-side program for supply resources. In calculating avoided costs of power and energy that an electric utility would otherwise have had to acquire, reasonable estimates shall be included of financial costs likely to be imposed by future regulations and legislation on emissions of greenhouse gases.
Pressure means the total load or force per unit area acting on a surface.
water meter means any apparatus for measuring or showing the volume of water supplied to, or of effluent discharged from any premises;
Calibration gas means a gas mixture used to calibrate gas analysers.
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.
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).
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.
