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.
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:
Alcohol concentration means the number of grams of alcohol per:
Excess Concentration means the sum of the following amounts, without duplication:
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).
Expandable condominium means a condominium project to which additional
iron ore concentrates means products (whether in pellet or other form) resulting from secondary processing but does not include metallised agglomerates;
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).
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;
