14. Data sheets completely and appropriately filled out. Data forms may be modified from the <br />Corps' standard version, but they must present all essential information necessary to make <br />a wetlands/non-wetlands determination. <br />Response: Copies of the 33 field data sheets used to delineation the wetland boundaries on this <br />site are found in the response to Item 10 wherein the questions of species lists are found. This specific <br />wetland field data sheet is the one printed off the Corps of Engineers - Sacramento District website. All <br />of the fields of the field data sheets are filled out. <br />15. At least one set of paired data points documented for each feature or complex. Additional <br />data forms may be necessary depending on various factors including the size and shape of <br />the wetlands on the site, difficulty in identifying a precise wetlands/uplands boundary, and <br />the width of any transition zones. <br />Response: At one set of paired field sample plots was placed in each wetland area which will <br />potentially be affected by future mining activities. Every wetland type or feature found on this property <br />has been sampled. <br />Additionally, before the Corps can complete its verification of the delineation, wetland <br />boundaries must be marked with flags or stakes. Flags or stakes must be individually <br />numbered and surveyed by traditional methods or by GPS equipment accurate to less than <br />one meter. The survey data must specify the geographic coordinate system used in <br />referencing the data, including projection and datum (e.g., Latitude-Longitude : NAD-27 or <br />UTM - Zone 10 : NAD-83). Data should be provided in a digital geographic information <br />(GIS) format to expedite review, with ESRI Shapefiles being the preferred format. The <br />Corps also strongly recommends that the property boundaries be flagged or staked and <br />surveyed. <br />Response: All wetland boundaries have been marked with individually numbered plastic wire pin <br />flags. Individual wetland sample plots are identified with wooden lathe with plastic flagging attached <br />which denoted specific wetland sample plots. All of the wetland boundaries were surveyed in using a <br />Trimble Model Geo XH Global Positioning System. This unit has a sub-meter accuracy. The coordinate <br />system used in this evaluation is the NAD-83, Colorado North datum. We have been told on numerous <br />occasions previously that it is not necessary to submit an electronic copy of this file, however, this <br />information is available if requested. All of the northern, easternly, southern and western boundaries of <br />the property were surveyed in prior to this wetland mapping effort. The southern property boundary is <br />really irrelevant due to the fact that the Yampa River forms a defined barrier to the south a few hundred <br />feet to the south of this project area. <br />Additional information often can expedite a wetland verification. Particularly helpful date <br />includes topographic maps, aerial and ground photographs, and related reports. Expanded <br />narrative reports may also clarify the investigation. However, the Corps emphasizes that <br />these reports should be succinct with only the relevant information presented. Irrelevant, <br />verbose, or perfunctory information will only delay the Corps' evaluation. <br />Response: Enclosed are a series detailed photographs of the proposed mine expansion area.
