Industrial General Permit Order

c. Additional parameters identified by the Discharger on a facility-specific
basis that serve as indicators of the presence of all industrial pollutants
identified in the pollutant source assessment (Section X.G.2). These
additional parameters may be modified (added or removed) in
accordance with any updated SWPPP pollutant source assessment;

d. Additional applicable parameters listed in Table 1 below. These
parameters are dependent on the facility Standard Industrial
Classification (SIC) code(s);

e. Additional applicable industrial parameters related to receiving waters
with 303(d) listed impairments or approved TMDLs based on the
assessment in Section X.G.2.a.ix. Test methods with lower detection
limits may be necessary when discharging to receiving waters with
303(d) listed impairments or TMDLs;

f. Additional parameters required by the Regional Water Board. The
Discharger shall contact its Regional Water Board to determine
appropriate analytical test methods for parameters not listed in Table 2
below. These analytical test methods will be added to SMARTS; and

g. For discharges subject to Subchapter N, additional parameters
specifically required by Subchapter N. If the discharge is subject to
ELGs, the Dischargers shall contact the Regional Water Board to
determine appropriate analytical methods for parameters not listed in
Table 2 below.

7. The Discharger shall select corresponding NALs, analytical test methods,,
and reporting units from the list provided in Table 2 below. SMARTS will be
updated over time to add additional acceptable analytical test methods.
Dischargers may propose an analytical test method for any parameter or
pollutant that does not have an analytical test method specified in Table 2 or
in SMARTS. Dischargers may also propose analytical test methods with
substantially similar or more stringent method detection limits than existing
approved analytical test methods. Upon approval, the analytical test
method will be added to SMARTS.

8. The Discharger shall ensure that the collection, preservation and handling of
all storm water samples are in accordance with Attachment H, Storm Water
Sample Collection and Handling Instructions.

9. Samples from different discharge locations shall not be combined or
composited except as allowed in Section XI.C.5 (Qualified Combined
Samples).

10. The Discharger shall ensure that all laboratory analyses are conducted
according to test procedures under 40 Code of Federal Regulations part
136, including the observation of holding times, unless other test procedures
have been specified in this General Permit or by the Regional Water Board.
