(1)
Identification of test procedures, application for alternative test procedures,
and method modifications.
a. The following is
adopted by reference: 40 CFR Part
136 (Guidelines Establishing Test Procedures
for the Analysis of Pollutants), as amended through August 28, 2017.
b. All parameters for which testing is
required by a wastewater discharge permit, permit application, or
administrative order, except operational performance testing, must be analyzed
using one of the following:
(1) An approved
method specified in
40 CFR Section
136.3;
(2) An alternative method that has been
previously approved pursuant to
40
CFR Section
136.4 or
136.5;
or
(3) A method identified by the
department, when no approved method is specified for the parameter in 40 CFR
Part
136 .
Samples collected for operational testing pursuant to 63.3(4)
need not be analyzed by approved analytical methods; however, commonly accepted
test methods should be used.
c. Applications for alternative test
procedures shall follow the requirements of
40
CFR Section
136.4 or
136.5.
d. Method modifications shall follow the
requirements of
40 CFR Section

Preservation Techniques, and Holding Times). Sample preservation should be
performed immediately upon collection, if feasible.

required by this chapter must be certified in accordance with 567-Chapter 83.
Routine on-site monitoring for pH, temperature, dissolved oxygen, total
residual chlorine, other pollutants that must be analyzed immediately upon
sample collection, settleable solids, physical measurements such as flow and
