2. Monitoring Requirements (Continued)
The analytical method selected for a parameter should be the one that
can measure the lowest detection limit for that parameter, unless the
State Standard is within the testing range of another approved method.
Any parameters that demonstrate instream levels in excess of those fdund
in Tables 1 , 11 & 111 of "Regulations Establishing Basic Standards And
An Antidegration Standard And Establishing A System For Classifying State
Waters, For Assigning Standards and For Granting Temporary Modification"
or appropriate Federal BPT standards may require additional monitoring as
directed by the Water Quality Control Division. The additional monitoring
will take place on a Monthly basis for a s.ix monthperiod. Parameters
that remain in excess of the table values listed above may be required to
meet instream limits and the permit may be modified to incorporate
these parameters as effluent limitations.
(B) For mine water or drainage from an open pit or underground
mine, a sample must be analyzed from each discharge point.
(C) For surface runoff controls, if there are several with
discharges, it is not necessary to sample the discharge
from each facility, provided that those sampled will be
representative of the various discharges. The minimum number
of discharges sampled should be the greater of the following:
two discharges, or 10% of the total number of discharges.
