(Duke Energy) Belews Creek Steam Station — Craig Road Landfill 401 Water Quality Certification Monitoring Dear Ms. Homewood: Com- (d--FcD- o 2 Belews Creek Steam Station Duke Energy Carolinas 3195 Pine Hall Road Belews Creek, NC 27009 Duke Energy is submitting the Water Quality monitoring report as required by Special Condition of Certification #9, of Water Quality Certification Number 3879 for impacts evaluation at the Craig Road Landfill Phase II Expansion project. The report includes monitoring for streams SC - 8 and SC -10. No other streams that are required for monitoring have been impacted by construction at this time. Should you have any questions regarding this report, please contact Joyce Dishmon at 336-623- 0238 or Joyce.Dishmon@duke-energy.com.

S`ummary��and.com,parison of assessments in.March,201'7' and.August 201.6: = . The habitat assessments of two, streams (SC8 and SC 10) in the vicinity of'Belews Creek- Steam ' Station (BCSS) Landfill were completed on March 23, '201.7 and August 29,` 2016.-T.he,overalI assessment score for habitat atSC8in,March2017 was SO, thesame�as in August 2016. SCI varied from 29 in Marchto 30 in_August, thts;is most: likely due to di"fferent methodology in scoring between the two collectors. Dissolved okygen (DO) was'noticeably lower in March'2047 . than in August.2016, while specific conductance -was higher, and pH was.slightly lower. The difference: could .be due to,the lack of:mov:ing water as most -of the stream was a standing pool and seasonality,. Temperatures'in March and August.reflected, normal` seasonal variation: Observati:ons of v.isible;land.use;indicated that forestation (10,%0) and'coal,ash'land fll(90%) was the same -during both March 2017 and August; 2016. A total of 13 rriacroin rt b t °t 'd ve e_ ra_e axa were i entified from SC8 an,March..Heterotrissocladius marcidus,..Nais cathmirnis, and''Lumbriculidae were,li'sted as -common.

In.

There were no, common taxa. Eight ofthe taxa -.found were rare;, and Physella henderson'i was, abundant`in the sample. This gave a- biotic; index score of 8.56 according:to the NCiBI small. stream requirement acid the bioclassi'fiwation was poor. There were 18 macroiriyertebrate, taxa. identified in August 2016. Only one of those taxa,. Atr-ichop.'ogon sp.,, was listed as abundant; while ,Chironomus"sp. Thienemannimyia sp, Anopheles SP, . and Chimarra aterrima were all common.
