QISP MODULE 1 COMPREHENSIVE
What would be considered an Advanced BMP? - ANSWER BMPs that infiltrate, reuse,
contain, retain, or reduce the volume of storm water runoff.
What test method should be used for TSS? - ANSWER SM 2540-D
Name a BMP that would be appropriate for the removal of particulates in the storm water
discharges from the industrial roof vents at this facility? - ANSWER Downspout media
filters
Casey's Metal Works and Custom Parts discharges to the earthen swale that discharges to
Dry Creek. Dry Creek is a 303(d) listed water body for toxicity. What do they have to do next?
- ANSWER The Discharger must identify industrial materials and activities that
generate toxic pollutants, with the potential to discharge. These identified pollutants are
required to be included in the facility's SWPPP and the Discharger is required to develop an
appropriate monitoring program for measuring the toxicity of the facility's industrial storm
water discharges.
True/False: If time weighted sampling is conducted and no volume or flow
estimates/information for the sampling event is included in the analysis, this is not allowed
in the IGP for storm water monitoring. - ANSWER True
Annual NAL exceedance - ANSWER Occurs when the average of all the analytical
results for a parameter from samples taken within a reporting year exceeds the annual NAL
value for that parameter listed in Table 2.
Instantaneous maximum NAL exceedance - ANSWER Occurs when two or more
analytical results from samples taken for any single parameter within a reporting year
exceed the instantaneous maximum NAL (for TSS and O&G) or are outside of the
instantaneous maximum NAL range for pH
, The SWPPP must describe any spills or leaks of a significant quanitity that discharged in the
previous _____ years. - ANSWER Five
Example of an NEC facility - ANSWER All operations are conducted within a building,
truck trailers about the enclosed loading bay (or dock), vehicles stored outside are well
maintained, all materials are stored indoors.
Sampling for copper is required for what SIC codes? - ANSWER 2491, 332X, 225X, 336X
True/False: Discharges of wash water to a storm drain inlet are prohibited. The Discharger is
required to eliminate all unauthorized NSWDs. - ANSWER True
What is the testing method for Nitrate + Nitrite Nitrogen? - ANSWER SM 4500-NO3-E
What is the definition of a QSE? - ANSWER a precipitation event that produces a
discharge for at least one drainage area and is preceded by 48 hours with no discharge from
any drainage area
What would allow NOI coverage for a New Discharger directly discharging to a water body
with a 303(d) listed impairment? - ANSWER The QISP demonstrated that the New
Discharger has eliminated exposure of the constituent for which the receiving water is
impaired.
True/False: If the QSE occurred within the previous 12 hours, the Discharger is required to
obtain a sample within 4 hours of the start of scheduled facility operating hours? -
ANSWER True
What are the reporting units for Table 2 parameters with the exception of pH? -
ANSWER mg/L
