Subject: Clarification of Fish Tissue Monitoring Report
Requirements for NPDES individual
stormwater permits
Dear Mr. Langley:
In response to your request dated July 13, 2017, we are sending clarification of the stormwater
NPDES permit requirement for reporting of fish tissue monitoring data. As you noted in your letter,
this is a follow up to our joint meeting with you and representatives from NPDES Wastewater and
Water Sciences Programs in the Division of Water Resources (DWR) on April 18, 2017.
NPDES individual stormwater permits for several Duke Energy plants require the permittee to submit
a copy of fish tissue monitoring results to the DEMLR Stormwater Program "within 30 days of
receiving results." This language is contained in the following NPDES Stormwater Permits:
Asheville Steam Electric Plant — NCS00095--/-- 575
Belews Creek Steam Station — NCS000573
Cape Fear Steam Electric Plant — NCS000574
Dan River Combined Cycle Station — NCS000572
Marshall Steam Station — NCS000548
Mayo Electric Generating Plant — NCS000580
Riverbend Steam Station — NCS000549
Roxboro Steam Electric Plant — NCS000581
W.H. WeatherspoonPlant —NCS000589
We understand that fish tissue analysis reporting requirements in companion wastewater permits for
these facilities allow a necessary time delay between fish tissue sample collection and analysis
because of the long process involved, and because those requirements dictate how reports are
presented. Therefore, for individual stormwater permits with this language, "results" may be
interpreted as the completed fish tissue data analysis report. If the final report is not yet complete
because the wastewater permit reporting timeframe is not aligned with the stormwater permit
renewal, the permittee should submit available fish tissue data to the DEMLR Stormwater Program at
the time of the permit renewal application. Subsequent data should be submitted to DEMLR at the
time of the wastewater permit application to DWR.
