From: Kulz, Eric Sent: Thursday, July 01, 2010 1:00 PM To: Xu, Lin Cc: Hill, Tammy; Tugwell, Todd SAW; Johnson, Alan; Stephen.Chapin@usace.army.mil; Dorney, John Subject: Five Mile Branch - Iredell County (#2006O200v2) Lin: DWQ has reviewed the above-referenced project documents and have a number of issues which require clarification and/or possible discussion by the IRT. The majority of the issues are related to the proposed wetland restoration. https://mail.nc.gov/owa/?ae=Item&t=IPM.Note&id=RgAAAAAAOgPoLNIPQZ06vHVR... 7/21/2010 FW: Responses to your comments on Five Mile Branch - Iredell County (#2006O2OOv2) Page 2 of 3 Vegetation Sweetgum and red maple should be removed from the planting list for the project. Although these species are common in Piedmont/Mountain Bottomland Hardwood communities, they tend to be very competitive in early successional systems (such as recently-planted mitigation sites) and will likely colonize on their own. Proposed Wetland Restoration Area Delineation It is unclear how the extent of restored wetland was estimated. The boundaries of the proposed wetland restoration in the design plan sheets do not appear to follow topographic contours or hydric soil lines. Please provide further explanation and additional maps, if necessary, to clarify how the total proposed wetland restoration area was calculated and mapped. Vernal Pools While we support the inclusion of a small number of vernal pools on a wetland restoration site, the mitigation plan does not provide details regarding the number and total area of constructed pools. These factors are significant since the plan proposes that they be included in the area receiving wetland mitigation credit. Soil While the site does appear to have hydric (Wehadkee) soil inclusions, we are concerned about the extent of wetland restoration (58.6 acres) proposed on an area that contains primarily Chewacla soils. We echo the concerns expressed in the original DA permit (May 9, 2006) as well as the suggestion that EEP not use any of the proposed wetland credits to offset permitted impacts until such time as success of wetland restoration begins to be demonstrated. Hydrology Success Criteria The proposed performance criteria for hydrology are "saturation within 12 inches of the soil surface for the hydroperiod dictated by the project reference or 5% of the growing season, whichever is less." DWQ believes that a hydroperiod reaching the minimum of these criteria will be inadequate to support the wetland system targeted for restoration. Table 5 in the Corps' 1987 Wetland Delineation Manual shows that areas with continual saturation or inundation for less than 5 percent of the growing season in most years are not wetlands, and DWQ does not support wetland mitigation credit for such areas. As Bottomland Hardwood Forests are expected to be "intermittently to seasonally inundated for long duration" (NC Wetland Assessment Method, ver. 1, April 2008), and based on results of reference hydrology monitoring in 2005 (Mitigation Plan, Dec 2009, p. 6- 2), we expect that the targeted hydroperiod is significantly greater than 5 percent, and varies depending upon landscape position (elevation, proximity to streams and surface runoff sources, etc.). In addition, although the mitigation plan indicates that monitoring will be representative, it does not include details regarding the placement of monitoring plots for vegetation and hydrology. Please provide a map and description of how monitoring will be structured to capture conditions across the site, including the hydrology gradient from the ditches that will remain open adjacent to 1-40. Monitoring Duration Please note that the federal Mitigation Rule states that monitoring periods should be extended for forested wetlands. This policy has been adopted by the IRT in NC. Considering the concerns regarding restoration on https://mail.nc.gov/owa/?ae=Item&t=IPM.Note&id=RgAAAAAAOgPoLNIPQZ06vHVR... 7/21/2010 FW: Responses to your comments on Five Mile Branch - Iredell County (#2006O2OOv2) Page 3 of 3 Chewacla soils, an extended monitoring timeframe for both vegetation and hydrology may be warranted. Please note we have copied pertinent USACE representatives and request input from them in resolving these issues. Please feel free to contact Tammy Hill at (919) 715-9050 or me if you have any questions regarding these comments. Eric Eric W. Kulz Environmental Senior Specialist N.C. Division of Water Quality 401 Oversight and Express Permitting Unit 2321 Crabtree Blvd., Suite 250 Raleigh, NC 27604 Phone: (919) 715-9050 Fax: (919) 733-6893 E-mail correspondence to and from this address may be subject to the North Carolina Public Records Law and may be disclosed to third parties https://mail.nc.gov/owa/?ae=Item&t=IPM.Note&id=RgAAAAAAOgPoLNIPQZ06vHVR... 7/21/2010 The following are reposes in blue to DWCYs comments dated July 1, 2010: Vegetation Sweetgum and red maple should be removed from the planting list for the project. Although these species are common in Piedmont/Mountain Bottomland Hardwood communities, they tend to be very competitive in early successional systems (such as recently-planted mitigation sites) and will likely colonize on their own. Sweet gum and red maple will not be included in the final construction plans. The planting table from the project specifications is attached. Proposed Wetland Restoration Area Delineation It is unclear how the extent of restored wetland was estimated. The boundaries of the proposed wetland restoration in the design plan sheets do not appear to follow topographic contours or hydric soil lines. Please provide further explanation and additional maps, if necessary, to clarify how the total proposed wetland restoration area was calculated and mapped. The proposed wetland restoration line has changes since the Restoration Plan was submitted. Please refer to the attached plan sheets. The main factor in determining the boundary of wetland restoration was the influence of the ditches and streams. The proposed wetland boundary runs parallel to the streams approximately 40-50 feet from the proposed top of bank. This is due to the obvious drawdown effect of the stream. The same is true for the ditches that will remain open. Where ditches are to be filled, the water table will be raised and wetlands restored. The proposed wetland line does follow contours where not influenced by a ditch or stream. Please refer to sheet 10. The northern proposed wetland line roughly follows the toe of slope at elevation 728 and 729. The same is true for the northern wetland line on sheets 12 and 13. It roughly follows the toe of the slope at elevation 723 and 724 Vernal Pools While we support the inclusion of a small number of vernal pools on a wetland restoration site, the mitigation plan does not provide details regarding the number and total area of constructed pools. These factors are significant since the plan proposes that they be included in the area receiving wetland mitigation credit. The 2009 Restoration Plan did not include the size and location of the proposed vernal pool because their inclusion was still conceptual. It was not until the earthwork calculation for filling the ditches and grading the stream banks was the number and size of the vernal pools determined. The attached plan sheets show the information on the vernal pools. Soil While the site does appear to have hydric (Wehadkee) soil inclusions, we are concerned about the extent of wetland restoration (58.6 acres) proposed on an area that contains primarily Chewacla soils. We echo the concerns expressed in the original DA permit (May 9, 2006) as well as the suggestion that EEP not use any of the proposed wetland credits to offset permitted impacts until such time as success of wetland restoration begins to be demonstrated. Due to the concerns of soils, none of the proposed wetland restoration acreage is included in the EEP's project asset. Further more, US Army Crops of Engineers in their recent granted 404 permit stated that no wetland credit would ne debited until the project is assessed during monitoring. However, it should be noted that a beaver constructed a dam on one of the ditches near Chimney Lane. Water was backed up over the road, there was wetland vegetation growing in the pond and ducks in the pond. Hydrology Success Criteria The proposed performance criteria for hydrology are "saturation within 12 inches of the soil surface for the hydroperiod dictated by the project reference or 5% of the growing season, whichever is less." DWQ believes that a hydroperiod reaching the minimum of these criteria will be inadequate to support the wetland system targeted for restoration. Table 5 in the Corps' 1987 Wetland Delineation Manual shows that areas with continual saturation or inundation for less than 5 percent of the growing season in most years are not wetlands, and DWQ does not support wetland mitigation credit for such areas. As Bottomland Hardwood Forests are expected to be "intermittently to seasonally inundated for long duration" (NC Wetland Assessment Method, ver. 1, April 2008), and based on results of reference hydrology monitoring in 2005 (Mitigation Plan, Dec 2009, p. 6-2), we expect that the targeted hydroperiod is significantly greater than 5 percent, and varies depending upon landscape position (elevation, proximity to streams and surface runoff sources, etc.). It should be pointed out that two gauges were installed in the reference wetland. The data presented in the report are from the gauge that was installed in the wettest area of the wetland. The second gauge was installed on the outer edge of the wetland and showed significantly different results. The maximum consecutive days of water within 12 inches of the ground surface was 20 day or 11.0 percent of the growing season. The second longest period of consecutive days was 8 days or 4.S percent of the growing season. As you stated, the hydroperiod "varies depending upon landscape position", as shown by the two reference gauges. Hydrology success criteria for the site should not be based on the maximum hydroperiod depicted by the reference. Therefore, using the other reference gauge and Table S of the 1987 Corps Manual, the success will be based on the conditions of the reference and on site wetlands at the same time period of the monitoring. Hydrologic success criteria will be ground water within 12 inches of the ground surface for a MINIMUM of S% of the growing. In addition, although the mitigation plan indicates that monitoring will be representative, it does not include details regarding the placement of monitoring plots for vegetation and hydrology. Please provide a map and description of how monitoring will be structured to capture conditions across the site, including the hydrology gradient from the ditches that will remain open adjacent to 1-40. Though not shown in the Restoration Plan, it is expected that hydrology will be monitored by installing north to south oriented gauge transects across the site, two west of Swann Road and one east of Swann Road. This will show the influence of the open ditches, stream and vernal pools. Vegetation will be monitored following NCEEP-CVS protocol. Monitoring plots will be installed in the wetland restoration areas. The exact number and location of monitoring devices is not known at this time. The locations and number will depend on the final constructed project. EEP will scope the monitoring phase of the project during the construction of project. More detail will be worked then. Monitoring Duration Please note that the federal Mitigation Rule states that monitoring periods should be extended for forested wetlands. This policy has been adopted by the IRT in NC. Considering the concerns regarding restoration on Chewacla soils, an extended monitoring timeframe for both vegetation and hydrology may be warranted. Typically, monitoring is a minimum of seven years or until the success criteria is met. The monitoring period can be increased if warranted.
