Wetlands Credits Sale opportunity has been identified in Rogers. As this is within the Illinois River basin, it is allowed for us to sell wetlands credits for this work. Staff is evaluating methods of pricing the credits that are available. 3. White River Stream Bank Restoration ANRC Grant partnership and budget adjustment is attached, recommending approval to provide $77,000 in matching funds to the Watershed Conservation Resources Center (WCRC)for a $200,000 grant from the Arkansas Natural Resources Commission (ANRC). The funds will go towards the restoration of a section of the White River at the Noland Wastewater Treatment Facility (WWTF) (see attached "Sediment and Nutrient Loading Estimate"). Due to this year's storm events the City has lost over fifteen feet of bank on the proposed section of the White River(see attachment aerial photos). The White River is on the ADEQ Arkansas impaired streams list and associated stream bank erosion directly increases the phosphorus loading in the river and Beaver Lake. By restoring this section of the river, studies indicate that the phosphorus loading would be reduced by 330 pounds per year which equates to 25 days of average discharge from the Noland Plant in current conditions. This grant from ANRC, and the work to be executed, is similar to the stream restoration project at Drake Field. The work can be entirely completed on land owned by the City of Fayetteville as part of the Noland WWTF, but the WCRC will also attempt to obtain easements from adjacent landowners. If obtained, these will enhance the project, but are not critical to project completion. All City funds will be expended on work on City property. The grant requires a $77,000 City match, which staff proposes to be paid for using Water/Sewer funds that are dedicated for site maintenance of the Noland WWTF. Staff requests this be forwarded to the City Council for consideration. 4. Biosolids Thermal Drying a. Thermal Drying design continues. ADEQ has stated, in writing, that there is no need for an air permit. We are still working with the gas company to determine whether gas or propane will be the most cost effective solution. We expect to advertise for bids within 60 days. W&S CommiueeAgwda10Aug10.doc WATER/SEWER COMMITTEE AGENDA MEETING DATE OF AUGUST 30, 2010 b. Solar Drying construction is scheduled for completion in February, 2011. Material handling equipment bids and purchases will be coming forward in the next few months, so the equipment will be on hand (and operators trained)when construction is completed. Equipment includes a skid steer loader, a spreader trailer, two conveyors, one 100 hp tractor (to pull the spreader), a small dump trailer, and a belted trailer for distribution. This equipment cost was included within the biosolids budget. Staff is developing a business plan for the end product, and intends to employ a sales mechanism similar to that currently used for hay sales. 5. Beaver Water District water treatment residuals discussion is underway to consider applying their residuals from the water treatment process on the Noland WWTF farm site east of the White River. We have a meeting scheduled with ADEQ in late August. 6. Water/Sewer Committee Meeting is Tuesday, September 14, 2010, 5:30 p.m., room 326.

The funds will go towards the restoration of a section of the White River at the Noland Wastewater Treatment Facility(WWTF) (see attached "Sediment and Nutrient Loading Estimate"). BACKGROUND Due to this year's storm events the City has lost over fifteen feet of bank on the proposed section of the White River(see attachment aerial photos). The White River is on the ADEQ Arkansas impaired streams list and associated stream bank erosion directly increases the phosphorus loading in the river and Beaver Lake. By restoring this section of the river, studies indicate that the phosphorus loading would be reduced by 330 pounds per year which equates to 25 days of average discharge from the Noland Plant in current conditions. DISCUSSION This grant from ANRC, and the work to be executed, is similar to the stream restoration project at Drake Field. The work can be entirely completed on land owned by the City of Fayetteville as part of the Noland WWTF, but the WCRC will also attempt to obtain easements from adjacent landowners. If obtained, these will enhance the project, but are not critical to project completion. All City funds will be expended on work on City property. The grant requires a $77,000 City match, which staff proposes to be paid for using Water/Sewer funds that are dedicated for site maintenance of the Noland property. ' This grant, executed under the City's recently adopted agreement with the WCRC, will be used for the restoration of stream banks along the White River in order to reduce annual phosphorus and sediment loads entering the river. The Environmental Protection Agency is increasingly focused on non-point source pollution entering the watersheds in Northwest Arkansas. This project will provide another quality example of the City's ongoing commitment to watershed protection, and will count as matching funds to the Beaver Water District Nutrient Reduction Agreement. BUDGETIMPACT The City will utilize $77,000 from WWTF operations funding as matching funds for the $200,000 grant from the ANRC. The attached budget adjustment transfers savings in WWTF fuel consumption to the White River stream bank restoration project. As this project is effectively property maintenance of WWTP land, it is an appropriate expenditure of water/sewer funds. White River Restoration Grant App Memo Aug l O.doc Sediment and Nutrient Loading Estimate for Riverbank Erosion on the White River A site visit was made in March 2010 by M.A. Van Eps, project engineer for the Watershed Conservation Resource Center(WCRC). During that visit photos of the eroding stream bank were taken. Based on the photos and observations made during the site visit, the following Bank Erosion Hazard Index (BEHI) attributes were qualified: , Bank Angle: 85 degrees Bank Height Ratio: 1.5 Root Depth: 20% of bank height l Root Density: 20% of root area < Toe Protection: 0% of length Bank Material: Silt Loam Additional Material Points: +5 Near Bank Sheer Stress was estimated to be "very high" along the eroding bank. The length of bank was estimated to be 700' in length. The average height of the bank was estimated to be 13'. Based on the BEHI variables, the BEHI rating would be"Very High" Using the BEHI/NBSS stream bank erosion prediction curves for the West Fork White River basin, the rate of erosion for the bank at the W WTP property was estimated. The estimated annual rate of erosion would be 1.2 feet per year. This erosion rate would be the rate for a "typical" or"average" year where no significant flood events have taken place. Of course when larger storm events take place, the rate of lateral erosion would be greater. For example in 2009 several large storm events caused erosion rates of 10' for portions of the site. An erosion rate of 1.2 ft/yr at the site would generate approximately 12,100 ft3/yror 448 yd3(30 dump truck loads) of sediment annually. That volume of sediment would have an equivalent weight of approximately 1,000 ton. The amount of phosphorus in soils varies. A conservative concentration of phosphorus in soils is 0.34 lb/ton. At that concentration, the amount of phosphorus entering the White River from riverbank erosion would be 330 lb/yr. Stabilization of this site would result in a reduction of sediment and phosphorus loads that would continue to be realized many years into the future. The water quality of Beaver Lake would be improved. Restoration will also improve aquatic habitat at the site. Without action, the site will continue to erode and the rate of erosion may increase over time. � aM c t � y 3 t r i { 'Qyyy'� y r� All It f I ,a ( It .rte(�rr�W'y' ,3'��j � 6y��t ' �`,T •1 w y < rA,Yr r D rG hY r t r y te' o y 3 i i 7t- . .i"". _ k _.. . a .. � a 'q " { - �e `�j r' . _. -..�� - �n "� ��AG. �,.. �•, �;h �� ::�:-- ':`r x �� .. -�a *: �� t. �:..
