QISP Module 1 Comprehensive Quiz
A Discharger's storm water flows off the industrial portion of a facility into an open
"conveyance." The conveyance combines with flow from non-industrial areas and then
leaves the property. The flow does not discharge to an MS4 conveyance and the flow
commingles with discharges from facility B's roadways until it ultimately discharges to a
Water of the US. Where is the most representative discharge location for storm water
associated with industrial activities? - ANSWER-The location where storm water
discharge leaves the industrial portion of facility A.
A New Discharger applying for an NOI that discharges through an MS4 that discharges
directly to a 303(d) listed impaired water body will have to demonstrate: - ANSWER-All
exposure to storm water of the pollutant(s) for which the water body is impaired has
been eliminated, the pollutant for which the water body is impaired is not present at the
Discharger's facility, or the discharge of any listed pollutant will not cause or contribute
to an exceedance of a water quality standard. This data and/or information is required to
be prepared by a QISP.
A New Discharger applying for NOI coverage is responsible for identifying what 303(d)
listed impaired water bodies? - ANSWER-Any 303(d) listed impaired water body that the
facility directly discharges to and is listed in Appendix 3 with impairments that have
been identified as "more likely to be associated with industrial storm water"
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.
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.
Define a New Discharger - ANSWER-1. A facility from which there is a discharge that
did not commence the discharge prior to August 13, 1979
2. Which is not a new source as defined in 40 CFR 122.29 and
3. which has never received a finally effective NPDES permit for discharges at the site
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.
