Fullwood, Executive Director MEMORANDUM TO: John R. Dorney, Division of Water Quality Dept. of Environment and Natural Resource FROM: Ron Linville, Regional Coordinator Habitat Conservation Program DATE: April 23, 2004 SUBJECT: Review of an application by Duke Energy Corporation, South Point Boating Access Area Upgrade, Lake Wylie, DWQ NO. 040589, Gaston County Duke Power Corporation is requesting 401 Water Quality Certification from the North Carolina Division of Water Quality. The NCWRC has reviewed information provided by the applicant, and field biologists on our staff are familiar with habitat values of the project area. These comments are provided in accordance with provisions of the Clean Water Act of 1977 (33 U.S.C. 466 et. seq.), the Federal Power Act (16 U.S.C. 791a et seq.), and the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d). Duke Power Corporation proposes to upgrade existing ramp facilities on Lake Wylie. The project is consistent with the Catawba/Wateree Project's recreation needs and shoreline management plan. Six ramps will be replaced with newer ramps. The launch area will be improved with additional curbing. Existing impervious areas will be repaved. Concrete (500 cubic yards) and riprap (200 cubic yards) will be used as fill for the launch facilities. Based on our review of the proposed activities, we do not object to the project as proposed. The following comments are provided for your consideration: 1. If concrete will be used, work must be accomplished so that wet concrete does not contact lake water. Any riprap used for lake fill must be clean material. 2. Work within the lake should not occur during the fish spawning period as specified in Duke Power's management plan for Lake Wylie. 3. Any new curbing and guttering should be accomplished (to the extent feasible and practicable) in a manner to direct parking lot runoff as sheet flow through vegetated buffers. Any curbing, guttering, and water quality best management practices should limit stormwater contamination of the lake by petroleum (and other vehicular) pollutants to the extent practicable. 4. Work in the lake should be accomplished during periods of low water level. Mailing Address: Division of Inland Fisheries • 1721 Mail Service Center • Raleigh, NC 27699-1721 Telephone: (919) 733-3633 ext. 281 • Fax: (919) 715-7643 5. Sediment and erosion controls should meet or exceed requirements of the NC Division of Land Resources requirements. 6. Native plants are preferred for seeding and stabilization activities. If necessary, nurse crops may be non-native annual plants. Sericea lespedeza and Bermuda grass should not be used unless alternative native plants are not suitable. Where practicable, diminished shoreline buffers should be restored. Additional information about native plants may be obtained from Ken Knight, Wildlife biologist at 704/982-1600. Additional planting suggestions and plant supply sources may be obtained from Elizabeth Hughes, Stewardship biologist at 828/651-8380. 7. The use of Low Impact Development (LID) materials and methodologies should be evaluated to determine if they may be suitable for this type of boat launch facility if and when extensive future parking lot renovations are needed. Information on LID measures may be found at www.lowimpactdevelopment.org. Thank you for the opportunity to review and comment on this project. If you have any questions regarding these comments, please contact me at 336/769-9453. Cc: R. Caccia, Duke Energy 0?0? ?v h ,`FRQG 7 d ?

This letter is requesting 401 certification for activities associated with this construction. The South Point Access Area is located in Gaston County. ?/This site was visited by Mr. Alan Johnson of the Mooresville office of the Division of Water Quality DENR on February 24, 2004. His comments regarding the overall project have been incorporated into this submittal. This site is required to comply with the Catawba-Wateree license issued by the Federal Energy Regulatory Commission (FERC), particularly the license requirement to ensure that growing needs for adequate public recreational access are met. This work is being performed to improve existing conditions and satisfy commitments in the 2001 Catawba-Wateree Shoreline Management Plan currently under review by FERC. The plan represents our attempt to meet expectations of the FERC requirements and was formulated after consultation with resource agencies including the U.S Fish & Wildlife Service and the North Carolina Wildlife Resources Commission. ,s The existing project footprint is nearly identical to the final footprint. The current boat launch will be removed and replaced with a new launch area that will allow access to deeper water. See the attached project descriptions and drawings for additional details regarding stormwater controls. The project includes the following elements to reduce the impacts of construction and operation: • The use of asphalt curbing is minimized to encourage sheet flow off the edge of the relatively flat parking area and across the mulched and/or grassed areas. • Additional mulch will be added under existing trees between the parking areas. www.dukepower.com J • Newly applied mulch will be used to stabilize certain areas between the parking lot and the full pond contour of Lake Wylie. As required, please find seven (7) copies of the `Pre-Construction Application Form' including a package that provides the project description, associated maps, drawings, and a list of property owners needed to process and issue a permit for this work. A check in the amount of $200 is enclosed to cover the 401 permit fee. Should you need additional information, please contact me at (704) 382-3696. Sincerely, Robert W.

Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. Page 5 of 8 USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on March 9, 2000, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as incomplete.

Page 8 of 8 DUKE POWER SOUTH POINT ACCESS AREA PROJECT DESCRIPTION February 23, 2004 Duke Power proposes to construct 6 new boat ramps at the South Point Access Area for the general public at the Lake Wylie Hydro Project. The project is located in Gaston County, North Carolina at the end of South Point Road. CURRENT CONDITION OF SITE The site currently has six boat ramps with 4 relatively new loading docks and a paved parking area with 165 vehicle/trailers spaces. PROPOSED DEVELOPMENT Six new ramps will be constructed in the same location as the six existing ramps. The old concrete ramps will be completely removed from the lake so the new ramps will rest completely on the bottom of the lake. The turnaround areas will be repaved with asphalt. The parking lot may be completely repaved depending on the bid price at the time bids are entertained but if not paved any major cracks in the existing asphalt will be sealed. The actual construction work will include: - Installation and removal of erosion control devices - Removal of existing boat ramps. - Clearing and removal of debris as necessary to accommodate project layout. - Repave/repair parking lot to accommodate 165 trailer parking spaces. Pavement will be designed to sustain light duty traffic. Asphalt curbing shall be placed along the turnaround and the parking lot edge except in areas designated for sheet flow runoff from parking area. - Inspect 2100 foot long entrance road for weak or failing areas and repair as necessary. - Preparation of ramp bed for (3) 60 foot long boat ramps and (3) 75 foot long boat ramps with class B riprap (five inch to 15 inch diameter stone). - Installation of (3) 60 foot long boat ramps and (3) 75 foot long boat ramps. Ramps expected to be constructed of 7 inch thick reinforced concrete mat with curbing to specified dimensions. - Installation of 10 foot wide by six inch thick concrete apron to adjoin boat ramps with concrete curb extending from ramp to edge of concrete apron. - Finish grading and grassing and/or rocking of edges along entrance road and parking lot, shoreline and other structural components to establish natural erosion control. - Evaluate current location of any trash can pad(s) and reinstall'or add as necessary. - Installation of FERC regulatory signs. BUFFER PROTECTION AND STORMWATER MANAGEMENT FACTS - South Point Access Area is an existing public access area. The overall dimensions of the parking lot will not be changed as a result of this upgrade. The areas where the boat ramps are located on site will be the only areas where construction occurs inside the 50 foot Catawba/Wateree buffer area. - Due to fact no grading will be occurring on this site there will be no need for any erosion control measures. - The existing parking area will utilize sheet flow or curb cutouts in strategic locations to assist in management of stormwater runoff. - The parking lot island and the west edge of the parking lot will be covered with a 6" layer of hardwood mulch to help to assist in management of stormwater runoff.

For the rock material placed underwater, the bucket on the grade-all can be used to compact and level the stone. The area to be graded or where fill Is laced should extend level 2-4' beyond the edge of the ramp and at a 2:1 grade down to the original grade. FORMING FOR THE RAMP -- A 2--4" layer of crusher run wilt need to be place, graded and lightly compacted under and 2' beyond the muip area in the concrete pouring area. This will provide material to drive the form stakes into. Two soparato continuous layers of 8 mil plastic will need to be placed on the graveled area to facilitate the moving of the ramp If it is to be pushed out beyond the water line. Install the forms and the rebar for the ramps on the plastic. Use steel benches to keep the rebsr off of the iastlr. and to separate the I" layers of rehar. - Create a 39 degree bevel on the underside of the lakeward end of the ramp to help the concrete slide over the rock when pushing the ramp into the water. Maintain a 2-3 thickness on the top of the bevel. - Install the steel angle iron push plate with Nelson etude on the bottom of the upper end of the ramp. POURING THE CONCRETE - Start pouring the concrete at the lower end of the ramp and work toward the top. - Screed and vibrate the concrete across the ramp surface. It the ramps will have curbing, make sure the concrete is level where the curb form will be added. - Start the grooving of the ramp surface with the modified float as soon as a 10' section has been screed. - Once the concrete slab has hardened, attach the curb forms and fill with concrete. Make sure to install 1/2" diameter PVC pipe vertically about V from the end of the ramp. This will allow the end the installation of a 8 piece of rebar to use as a guide to make sure of the alignment of the ramp. - Vibrate and then finish the top surface of the concrete. PUSIIING THE RAMP Remove the concrete forms. ppee pp gg atsV intervals from the top of the curb. pUee en different lcolor riblbon for &a Sesired depth at the end of the ramp when fully pushed. Position a dozer at the top end of the ramp and put the blade against the angle iron push plate. In addition, it Is suggested to use a piece of channel Iron between the dozer blade and ramp to provide extra protection to the concrete. For the 80' ramps, it may take a second dozer. Push the ramp out to the desired depth and keep it aligned by using a transit sighting on the rebar. Leave a 5-10' section of the ramp out of the water so the concrete forms can be Installed and the next section of ramp can be tied to the first section by working out of the water. If the first section of ramp is the only section to be pushed, you can form and pour the remaining length of ramp in place. INSTALLING THE APRON - The upper 10' of ramp and the 10' apron connecting multiple romps is used to transition from the 157 ramp slope to the slope of the turnaround area. - The top end of the ramp I. 1 above the full pond elevation and has rebar extending from the end to cenntlet with the welded wire mesh used in the apron. - The sides of the apron are on the same 50' radius curve that Is used for the turnaround area. - The edges of the apron have a curb that goes from the height of the ramp curb down to a height of 6" to watch will the asphalt. curb around the edge of the turnaround. A single layer of WWF 4x4-W4x W4 (ASTM A185) Is installed in the 8" thick apron and tied to the ramp with rebar. Steel benches are used to position the wire mesh in the concrete. Where there Is a 10' space between ramps (for the installation of an 8' wide loading pier) the curb Is perpendicular to the apron and slopes to a height of 3.6" over a distance of 5". - Where there is a 4' gap between the ramps (just for spacing) the curbs on the adjacent ramps converge and slope to a height of 3.5 over a distance of 5. The apron just has a broom finish to the surface. BACKFILLING AROUND THE RAMPS - Surge stone is placed to within 6' of the top of the curbs on the ramps. A 4-8 layer of railroad ballast stone is placed on top of the surge stone to make the surface easier to walk on. - This stone can be lightly packed with a backhoe bucket and will need to be dressed up with additional atone as the atone settles. SPECIAL NOTES 11 there will be a substantial depth of surge stone needed for fill, you will need to install your pier pclings prior to lacing the fill. When installing the concrete abutment for the pier, make the abutment fill the entire width between the ramps. - Try to design the length of the ramp so there will be 4-8' of water over the end of the ramp at maximum drawdown. - When the first section of ramp is poured and ready to push, you will need to bend the rebar protruding front the end of the ramp The top end of the curb should be painted yellow. If you are going to build a lot of the ramps, it is good to have some steel forms made.
