<br /> <br /> 3 <br /> <br />Bouma suggested other outreach opportunities, such as the Last Friday events in <br />Hillsborough and the upcoming Earth Evening event on April 29 in Hillsborough. Hintz <br />suggested that CFE members volunteer at these events. Wegman and Hintz said better <br />signage is needed to direct people to the Earth Evening venue because last year it was <br />not easy to find due to the other things going on in downtown Hillsborough. Bouma said <br />he would reiterate that request to Marabeth Carr and other Earth Evening organizers. <br /> <br />Davis said this year’s Earth Evening will include tables with information from DEAPR, <br />Eno River Association, Solid Waste Management, 4H, and several other entities. He <br />said there will be a display about the new Hollow Rock Nature Park that will open in <br />May. Davis also noted a Movie in the Park will occur immediately following the Earth <br />Evening. CFE members discussed the possibility of showing worthwhile environmental <br />documentaries in the future, which might help draw people to the event. <br /> <br />Davis asked for volunteers to help at Last Fridays and Earth Evening. Kaiser said he <br />would like to help out and suggested this be on the April meeting agenda. <br /> <br />Wegman thanked Davis and Bouma for the information and asked that this matter be <br />discussed further at the April meeting. <br /> <br />V. Impaired Streams in Orange County – Davis presented a draft list of “impaired” rivers <br />and streams in Orange County that was released recently by the State of North Carolina. <br />He first showed a map of the impaired surface waters across the entire state, noting how <br />these rivers and streams tend to be concentrated around urban areas. <br /> <br />Davis explained that the NC Division of Water Resources assigns a designated use to <br />surface water bodies (such as drinkable, swimmable, or fishable), and then assesses <br />each water body using a variety of standards to determine if they are meeting that use. <br />If a river or stream is not meeting the designated use they are included on the “303d list” <br />of impaired waters. Davis said after the State releases its list and receives public <br />comment, the list and methodology goes to the US EPA for approval. The US EPA will <br />usually focus on reviewing methodology, and will rarely challenge specific State findings. <br /> <br />Davis reported that all the waters in the state are considered “impaired” for fish <br />consumption due to mercury from coal fired power plants, however that is not a reason <br />to include them on the 303d list. <br /> <br />Davis said over 1,200 waterways in the state were identified as impaired under Category <br />5 assessments, which require a determination of the TMDL (Total Max Daily Load, or <br />how much of a particular chemical a water can body assimilate and still function). He <br />explained that a TMDL caps pollution allowed in that watershed. This total is then split <br />among the known sources of that pollution and fines can be levied if those sources <br />exceed their allotment. Davis said short of a TMDL, under Category 4 a waterway might <br />be covered by a nutrient load restriction like Jordan Lake Rules. Category 4 waters are <br />impaired, but (by definition) are not included on the 303d list. They do not need the <br />development of a TMDL because they are “covered” by an alternative to a TMDL, such <br />as the Jordan Lake Nutrient Management Strategy. <br /> <br />Davis said a lack of healthy populations of benthic macroinvertebrates is often the <br />reason why a stream is designated as impaired. Assessments occur no more than once <br />every five years in selected waterways. Monitoring does not always occur in the same <br />season, which can lead to varying results. Droughts also impact the results significantly.
