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 determined for each pollutant for which a minor source baseline date is established and shall include the following:
Maximum contaminant level goal or “MCLG” means the maximum level of a contaminant in drinking water at which no known or anticipated adverse effect on the health of persons would occur, and which allows an adequate margin of safety. MCLGs are nonenforceable health goals.
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.
Minimum Level (ML) means the concentration at which the entire analytical system must give a recognizable signal and an acceptable calibration point. The ML is the concentration in a sample that is equivalent to the concentration of the lowest calibration standard analyzed by a specific analytical procedure, assuming that all the method-specified sample weights, volumes and processing steps have been followed.
Critical Test Concentration or "(CTC)" means the specified effluent dilution at which the Permittee is to conduct a single-concentration Aquatic Toxicity Test.
