This number is calculated as the easement acreage minus any existing mature tree stands that were not subject to supplemental planting of the understory, the channel acreage, crossings or any other elements not directly planted as part of the project effort. = The acreage within the easement boundaries = Encroachment may occur within or outside of planted areas and will therefore be calculated against the overall easement acreage. In the event a polygon is cataloged into items 1, 2 or 3 in the table and is the result of encroachment, the associated acreage should be tallied in the relevant item (i.e., item 1,2 or 3) as well as a parallel tally in item 5. = Invasives may occur in or out of planted areas, but still within the easement and will therefore be calculated against the overall easement acreage. Invasives of concern /interest are listed below. The list of high concern spcies are those with the potential to directly outcompete native, young, woody stems in the short-term (e.g. monitoring period or shortly thereafter) or affect the community structure for existing, more established tree /shrub stands over timeframes that are slightly longer (e.g. 1 -2 decades). The low /moderate concern group are those species that generally do not have this capacity over the timeframes discussed and therefore are not expected to be mapped with regularity, but can be mapped, if in the judgement of the observer their coverage, density or distribution is suppressing the viability, density, or growth of planted woody stems. Decisions as to whether remediation will be needed are based on the integration of risk factors by EEP such as species present, their coverage, distribution relative to native biomass, and the practicality of treatment. For example, even modest amounts of Kudzu or Japanese Knotweed early in the projects history will warrant control, but potentially large coverages of Microstegium in the herb layer will not likley trigger control because of the limited capacities to impact tree /shrub layers within the timeframes discussed and the potential impacts of treating extensive amounts of ground cover. Those species with the "watch list" designator in gray shade are of interest as well, but have yet to be observed across the state with any frequency. Those in are of particular interest given their extreme risk /threat level for mapping as points where isolated specimens are found, particularly ealry in a projects monitoring history. However, areas of discreet, dense patches will of course be mapped as polygons. The symbology scheme below was one that was found to be helpful for symbolzing invasives polygons, particulalry for situations where the conditon for an area is somewhere between isolated specimens and dense, discreet patches. In any case, the point or polygon /area feature can be symbolized to describe things like high or low concern and species can be listed as a map inset, in legend items if the number of species are limited or in the narrative section of the executive summary.

As per SCO contract 0406210 -02 Special Provision Section 6 0, bare roots were to be planted at 680 stems per acre, and containerized seedlings at 435 per acre, of those 80% minimum were to survive for one year from Project Acceptance The warranty period began 2/28/2019 and will expire 2/28/2012 Field data is summarized below and supplemental information about replant requirements is attached. Vegetation assessment methodology Planted vegetation at the Greenbrier Creek site has been assessed once since February 2011 project planting, on September 28, 2011 by the Owner. Data collected during the sampling effort report higher plant mortality than contractually permissible Warranty replant numbers are based on the data collected Field methodology and data are described below September 28, 2011 sampling Fourteen (14) vegetation plots were established, each 1,076 sq ft (25m x 4m) in Zone 4 of the original planting plan All planted bare root and shrubs present within the plot were counted towards the warranty criteria, including those that were top -dead but were re- sprouting at their base.

Monitoring Year 2 of 5 (2013) EEP Project Number 671 September 2013 Alamance and Chatham Counties, North Carolina Appendices Y 1,11co stem PROGRAM August 2, 2007 Rich Gannon North Carolina Division of Water Quality 1617 Mail Service Center Raleigh NC 27699 -1617 SUBJECT June 12, 2007 EEP Nutrient Offset meeting summary This correspondence is provided to summarize our June 12, 2007 meeting with you, Tom Reeder, Suzanne Klimek, Jim Stanfill and myself The meeting was held in an attempt to clarify some issues related to EEP's use of riparian buffers to mitigate for Nitrogen and Phosphorus It is important to come to a common understanding on these issues related to nutrient offset mitigation credit generation as we plan the implementation of mitigation projects. Below are the topics we discussed as they were presented in our May 14, 2007 letter to you A summary of our discussions is below each topic in italics We invite your input and response to ensure we have captured our discussions accurately Riparian Buffer N Reduction Efficiencies. With regard to the January 4, 2007 report detailing your discussions of NO3 — N reduction, we would like to clarify whether the benefits of land use change and the benefit of periodic overbank flooding have been considered in the buffer efficiency calculations. We also want to discuss EEP's buffer widths and the efficiencies that should be used for buffers 100 feet or greater A 50% efficiency was and is used in our calculations of buffer efficiency for our offset projects Our projects typically have 200 foot buffer widths The underlying questions here were — Can EEP get more credit for buffers that are wider than 50 feet by using higher efficiency rates as shown in the NLEW paper? As a group we agreed to use an overall efficiency of 50% for riparian buffers used to offset nutrients regardless of width Rich Gannon noted that although higher efficiencies were suggested in the "NLEW" paper for buffers wider than 50 feet, these numbers are not widely verified It is therefore appropriate to use 50% to determine reductions Jim Stanfill agreed noting that EEP buffers are often 200 feet wide and although using a higher efficiency would generate greater mitigation credit, the 50 % number had been used up to this point and EEP would continue to use that to calculate credits 2 Level Spreaders The use of level spreaders on riparian buffers not subject to concentrated flow needs to be discussed It is our understanding that guidance on level spreaders may only be meant to apply to those riparian buffers being used as "onsite" treatment BMPs by permitees We assume the guidance does not apply to riparian buffer restoration as typically done by EEP, but would like to discuss and get clarification on that issue The standard is to provide dose flow through buffers Because EEP would often need to actually clear portions of riparian buffers to install level spreaders, and also because EEP's buffers are often 200 feet wide, we do not think the use of level spreaders is necessary as long as die flow is maintained Tom Reeder and Rich Gannon agreed that level spreaders would not necessarily be needed on EEP buffers in rural areas where d ffuse flow is not an issue YWA RmtDYG;L9...

Land Use Change- If EEP purchases agricultural land to do riparian buffer restoration we believe EEP should get credit for restoration of the entire buffer width That is, the first 40 feet of buffer would not be excluded from our credit calculations The argument for this is that while the act of EEP purchasing the-property may have changed a property's land use and', therefore; made -it subject to the buffer rules, the EEP is actually implementing an active riparian buffer restoration project on that land, not simply taking it out of agricultural use Furthennore, if EEP does not purchase these lands, there will be no land use change Torn and Rich agreed with this statement- EEP should get credit for the ealir e, width t estored We also have some questions about the Jordan nutrient offset trading; program, but staff are still reviewing the information that has been released. EEP will need to provide comments on the Jordwi rules to ensure the fees are set capproprtately and the requirements (service area) are attainable `flits area,is hkely to have ltigher,implementation costs and less opportwitty for lower cost buffers as nutrient offset innigation ff JEEP will accept payments in thit area, we initst be able to afford to unplement projects S EEP's Nutrient Offset Accounting Methods, Regarding EEP's mdrient offset requirements - Jun Stanfill discussed how we measure the lolal pounds for 30 years when ive accept a trulrient offset perymeni and take on a requirement Our projects are .Yet up to offset a total numbers rf pounds and, therefore. we may have "shorter" (less than 30 years) more intense projects. Rich and 'font were in agreement with Our accounting nielhas 6 Riparian Buffer Mitigation Site location — clarification of intent of rules: fn the Randleman watershed (for Cape Fear 03), EEP staff have questioned inhere- upstream or down streattt- rn the watershed the mitigation should take place Xhligatton that EEP already has dmvneream of the reservoir can be used but new pursuits should he upstream in Larder to protect the reservoir Likewise, ur Catativba neiv projects should be downstream of Lake Jantes to be used as mitigation credit EEP .Staff also clay f ed drat the rules do not have a tune requireinent for EEP to provide the mitigation- but that the program uses the .same time requrreinents as the WOU. Tom und'Rich were calsv agreeable to this i Rrch requested that EEP allow for transparencies in its program and asked for us to provide as inuch data as possible in our annual report and work on information to be mciuded an EEPs Web site EEP agreed and is workitig to set up a specV4, web page at the program 's web site devoted to the l+utrwnt Offset Prograin Thank, you for taking the time to discuss these issues with us.
