Net concentration means the difference between the concentration of a given substance in a sample taken of the discharge and the concentration of the same substances in a sample taken at the intake which supplies water to the given process. For the purpose of this definition, samples that are taken to determine the net concentration shall always be 24-hour composite samples made up of at least six increments taken at regular intervals throughout the plant day.
Derived air concentration (DAC) means the concentration of a given radionuclide in air which, if breathed by the reference man for a working year of 2,000 hours under conditions of light work, results in an intake of one ALI. For purposes of these regulations, the condition of light work is an inhalation rate of 1.2 cubic meters of air per hour for 2,000 hours in a year. DAC values are given in Part 4, Appendix 4B, Table 4B1, Column 3.
Critical Test Concentration or "(CTC)" means the specified effluent dilution at which the Permittee is to conduct a single-concentration Aquatic Toxicity Test.
Baseline concentration means that ambient concentration level that exists in the baseline area at the time of the applicable minor source baseline date. A baseline concentration is deter- mined for each pollutant for which a minor source baseline date is estab- lished and shall include:
median concentration means that half of the homes in a county are expected to be below this value and half to be above it. All houses contain some radon, and a few houses will contain much more than the median concentration. The only way to accurately assess long-term exposure to radon in a specific house is through long-term testing (sampling the indoor air for a year or more). The EPA recommends that all homes be tested for radon. Columbia University's "Radon Project" website offers help to homeowners in assessing the cost vs. benefit of testing a specific house for radon or modifying it for radon reduction (see http://www.stat.columbia.edu/~radon/).
Alcohol concentration means the number of grams of alcohol per:
In-stream Waste Concentration or "(IWC)" means the concentration of a discharge in the receiving water after mixing has occurred in the allocated zone of influence.
Background concentration means such concentration of that substance as is present in:
Excess Concentration means, without duplication, the sum of the following amounts:
Concentration means the weight of any given material present in a unit volume of liquid. Unless otherwise indicated in this permit, concentration values shall be expressed in milligrams per liter (mg/l).
iron ore concentrates means products (whether in pellet or other form) resulting from secondary processing but does not include metallised agglomerates;
General purpose radiographic x-ray system means any radiographic x-ray system which, by design, is not limited to radiographic examination of specific anatomical regions.
Cannabinoid concentrate means a substance obtained by separating cannabinoids from marijuana by:
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.
Proved Developed Non-Producing Reserves means oil and gas reserves that, in accordance with Petroleum Industry Standards, are classified as both “Proved Reserves” and “Developed Non-Producing Reserves.”
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.
Measurable means the amount of the transaction can be determined and “available” means collectible with the current period or soon enough thereafter to be used to pay liabilities of the current period. State equalization monies are recognized as revenue during the period in which they are appropriated. A one- year availability period is used for revenue recognition for all other governmental fund revenues.
Residual disinfectant concentration (“C” in CT cal- culations) means the concentration of disinfectant measured in mg/l in a representative sample of water.
information gathering measures means laws and administrative or judicial procedures that enable a Contracting Party to obtain and provide the requested information;
Geothermal fluid means water in any form at temperatures greater than 120
Total hydrocarbons (THC) means the sum of all volatile compounds measurable by a flame ionization detector (FID).
Proved Developed Producing Reserves means Proved Reserves which are categorized as both “Developed” and “Producing” in the Definitions, “Proved Developed Nonproducing Reserves” means Proved Reserves which are categorized as both “Developed” and “Nonproducing” in the Definitions, and “Proved Undeveloped Reserves” means Proved Reserves which are categorized as “Undeveloped” in the Definitions.
Instantaneous flow measurement means the flow measured during the minimum time required for the flow-measuring device or method to produce a result in that instance. To the extent practical, instantaneous flow measurements coincide with the collection of any grab samples required for the same sampling period so that together the samples and flow are representative of the discharge during that sampling period.
Measurement Point means the emission source for which continuous emission measurement systems (CEMS) are used for emission measurement, or the cross-section of a pipeline system for which the CO2 flow is determined using continuous measurement systems;
Deactivation Avoidable Cost Credit means the credit paid to Generation Owners pursuant to Tariff, Part V, section 114.
Low-level radioactive waste or “waste” means radioactive material that consists of or contains class A, B, or C radioactive waste as defined by 10 C.F.R. 61.55, as in effect on January 26, 1983, but does not include waste or material that is any of the following:
