March 2015 summary of assessment and comparisons with August 2014. The habitat assessments of two streams (SC8 and SC 10) in the vicinity of Belews Creek Steam Station (BCSS) were completed on March 24, 2015. These assessments were compared to those conducted at the same locations on August 28, 2014. The overall assessment score at SC8 in March 2015 was 52, the same as in August 2014. Dissolved oxygen (DO) and specific conductance were higher in March 2015 than in August 2014, while the pH was lower. Temperatures in March and August reflected normal seasonal variation. Observations of visible land use indicated that forestation (10 %) and coal ash land fill (90 %) was the same during both March 2015 and August 2014. The average depth of the stream bed was 0.07 m in March 2015 and 0.05 in in August 2014 with maxima of 0.38 in and 0.40 in in March 2015 and August 2014, respectively. A total of six macromvertebrate taxa were identified from SC8 in March of 2015 as well as numbers of fish, crayfish and salamanders. Physidae, Dytiscidae and Oligochaeta were listed as common, while rare forms included Bittacomorpha, Tipulidae and Hydrophilidae. In August 2014, eight macromvertebrate taxa were observed, along with some fish. Chironomidae, Dytiscidae, and Ologochaeta were again listed as common, while Bittacomorpha, Helichus, Corbicula, and Cordullidae were rare. Fish were also listed as common. Overall, both assessments listed the stream as having poor potential for wetlands development due to it being designated as a landfill site. Other scores listed for SC8 in March 2015 were the same as in August 2014. The overall assessment score at SC10 in March 2015 (30) was the same as in August 2014. The DO was higher in March 2015 than in August 2014, while the temperature, conductivity, and pH values were lower in March 2015 than in August 2014. Temperature was much lower due to seasonal differences. Tern percent of land use was in forestation during both assessments, while 90% of land use was as coal ash land fill. The survey during both assessments showed the stream to be nearly nonexistent (width= 0.15m, depth= 0.01m — 0.02 m). A total of six macromvertebrate taxa were identified from SC 10 in March of 2015. Chironomidae and Oligochaeta were rated as abundant, Dixidae and Tipulidae were common. Dytiscidae and Cordulegastridae were rare. Only four taxa were also recorded in August 2014. Oligochaeta were common, while Ceratopogonidae, Tipulidae, and Chironimidae were listed as rare. Non - macroinvertebrate taxa were not observed at this site in either Match 2015 or August 2014. Overall, both assessments listed the stream as having poor potential for wetlands development. Other scores listed for SC 10 in March 2015 were the same as in August 2014 due to it being designated as a landfill site.
