40 CFR Appendix Tables to Part 132 - Tables to Part 132
EPA recommends that metals criteria be expressed as dissolved concentrations (see appendix A, I.A.4 for more information regarding metals criteria).
(a)
a CMC = CMC tr.
b CMC d = (CMC tr) CF. The CMC d shall be rounded to two significant digits.
c CMC should be considered free cyanide as CN.
d CMC = CMC t.
Notes:
The term “n/a” means not applicable.
CMC is Criterion Maximum Concentration.
CMC tr is the CMC expressed as total recoverable.
CMC d is the CMC expressed as a dissolved concentration.
CMC t is the CMC expressed as a total concentration.
(b)
a CMC tr = exp {mA [ln (hardness)] + bA}.
b CMC d = (CMC tr) CF. The CMC d shall be rounded to two significant digits.
c CMC t = exp mA {[pH] + bA}. The CMC t shall be rounded to two significant digits.
Notes:
The term “exp” represents the base e exponential function.
The term “n/a” means not applicable.
CMC is Criterion Maximum Concentration.
CMC tr is the CMC expressed as total recoverable.
CMC d is the CMC expressed as a dissolved concentration.
CMC t is the CMC expressed as a total concentration.
EPA recommends that metals criteria be expressed as dissolved concentrations (see appendix A, I.A.4 for more information regarding metals criteria).
(a)
a CCC = CCC tr.
b CCC d = (CCC tr) CF. The CCC d shall be rounded to two significant digits.
c CCC should be considered free cyanide as CN.
d CCC = CCC t.
Notes:
The term “n/a” means not applicable.
CCC is Criterion Continuous Concentration.
CCC tr is the CCC expressed as total recoverable.
CCC d is the CCC expressed as a dissolved concentration.
CCC t is the CCC expressed as a total concentration.
(b)
a CCC tr = exp {mc[ln (hardness)] + bc}.
b CCCd = (CCC tr) (CF). The CCC d shall be rounded to two significant digits.
c CMC t = exp {mA[pH] + bA}. The CMC t shall be rounded to two significant digits.
Notes:
The term “exp” represents the base e exponential function.
The term “n/a” means not applicable.
CCC is Criterion Continuous Concentration.
CCC tr is the CCC expressed as total recoverable.
CCC d is the CCC expressed as a dissolved concentration.
CCC t is the CCC expressed as a total concentration.
