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/).
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.
Alcohol concentration means the number of grams of alcohol per:
Excess Concentration means, without duplication, the sum of the following amounts:
Cannabinoid concentrate means a substance obtained by separating cannabinoids from marijuana by:
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.
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.
iron ore concentrates means products (whether in pellet or other form) resulting from secondary processing but does not include metallised agglomerates;
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:
Cannabis concentrate means cannabis that has undergone a process to concentrate one or more active cannabinoids, thereby increasing the product’s potency. Resin from granular trichomes from a cannabis plant is a concentrate for purposes of this division. A cannabis concentrate is not considered food, as defined by Section 109935 of the Health and Safety Code, or a drug, as defined by Section 109925 of the Health and Safety Code.
Residual disinfectant concentration (“C” in CT cal- culations) means the concentration of disinfectant measured in mg/l in a representative sample of water.
Background concentration means such concentration of that substance as is present in:
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).
Marijuana concentrate means any type of marijuana product consisting wholly or in part of
concentrates means flavoring ingredients and, depending on the product, sweeteners used to prepare syrups or finished beverages;
Geothermal fluid means water in any form at temperatures greater than 120
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.
Nitrogen oxides means nitric oxide and nitrogen dioxide, expressed as nitrogen dioxide (NO2);
Critical Test Concentration or "(CTC)" means the specified effluent dilution at which the Permittee is to conduct a single-concentration Aquatic Toxicity Test.
Concentrate means the product of a process of extraction of metal or a metallic mineral from mineral ore that results in substantial enrichment of the metal or metallic mineral concerned;
Excess Concentration Amount means, as of any date of determination on which any one or more of the Concentration Limitations are exceeded, an amount (calculated by the Servicer and without duplication) equal to the Dollar Equivalent of the portion of the Adjusted Principal Balance of each Eligible Collateral Loan that causes such Concentration Limitation to be exceeded.
Total tetrahydrocannabinol means the same as that term is defined in § 3.2-4112.
Medical marijuana concentrate means a specific subset of Medical Marijuana that was produced by extracting cannabinoids from Medical Marijuana. Categories of Medical Marijuana Concentrate include Water-Based Medical Marijuana Concentrate, Food-Based Medical Marijuana Concentrate and Solvent-Based Medical Marijuana Concentrate.
Total hydrocarbons (THC) means the sum of all volatile compounds measurable by a flame ionization detector (FID).
Daily Concentration means the concentration of a substance as measured in a daily composite sample, or, arithmetic average of all grab sample results defining a grab sample average.
Tetrahydrocannabinol means the same as that term is defined in § 3.2-4112.
