WALDO COUNTY SOIL AND WATER CONSERVATION DISTRICT REQUEST FOR QUALIFICATIONS (RFQ) PLANNING CONSULTANT SERVICES FOR IMPAIRED LAKE WATERSHED PLAN DEVELOPMENT The Waldo County Soil and Water Conservation District (District) is requesting Statements of Qualifications from interested and qualified Consultants for Professional Planning Consultant Services in order to assist in the development of an update to the Unity Pond (Lake Winnecook) Watershed-Based Management Plan. The purpose of the Unity Pond (Lake Winnecook) Watershed-Based Management Plan Project is to create a comprehensive plan for Unity Pond (Lake Winnecook) with well-developed implementation strategies that effectively improve the water quality of the lake over the next 10 years Overview The District has been awarded a grant and is under contract with the Maine DEP to develop a watershed-based plan for the Pond (Lake). Funds for this project were provided by the USEPA under Section 319 of the Clean Water Act. Unity Pond sits at 175 feet above sea level. The pond has a maximum depth of 12 meters (41 feet), an average depth of 6 meters (19 feet), and an estimated volume of 57,959,154 m3. The pond flushes 1.23 times per year.i The watershed is drained by three major tributaries- Meadow Brook, Bithers (bog) Brook, and Carlton Stream. Meadow Brook originates in the western watershed in a large tamarack bog complex, Bithers Brook flows from the east, and Carlton Stream flows from the north at the outlet of Carlton Pond (a.k.a. Carlton Bog). A single outlet, Sandy Stream, is located at the southern end of the pond. A railroad bed follows the shoreline of Unity Pond on the southwestern shore, where a railway trestle crosses over the pond’s outlet as it becomes Sandy Stream. Sandy Stream drains to a wetland area to the south, then continues into Twenty-five Mile Stream, flowing into the Sebasticook River in Burnham, and eventually draining to the Kennebec River in Winslow. At one time, Sandy Stream was considered the major inlet to Unity Pond, located adjacent to the pond’s outlet, Twenty-five Mile Stream. The outlet has been a source of concern over the years, as locals have historically suggested that a poorly designed railway bed and trestle dramatically altered the natural flow to Unity Pond. Prior to the construction of the railway trestle in 1870, the Sandy Stream Watershed (~65 sq. mi.) that includes Freedom Pond (a.k.a. Sandy Pond) and Halfmoon Stream, flowed from the south directly into Unity Pond. Construction of the railway and trestle altered the natural flow of Sandy Stream and Twenty-five Mile stream and created the wetland complex to which Unity Pond now drains. Stream flow modifications are believed to be causing backflushing at the Unity Pond outlet. Typically, Sandy Stream flows into the wetland area southwest of the Unity Pond outlet and continues into Twenty-five Mile Stream. However, during significant rain events, and when water levels are low in the pond, it is possible that Sandy Stream may bypass the wetland and flow into Unity Pond. When backflushing occurs, the Unity Pond watershed increases in size by about 65 square miles.ii Sixteen percent of the watershed is categorized as urban development. This includes shoreline development (0.8%), non-shoreline development (5.5%), agricultural land (7%), and operated forest lands (2.9%). Undeveloped land (undisturbed/unmanaged forest, grassland, scrub shrub, and wetland) make up 72% of the watershed, and surface water accounts for the remaining 12% if the watershed land area. Historically, agriculture has had a relatively large impact on Unity Pond’s water quality. In 1974 there were about 420 farms in the watershed averaging 200 acres in size.1 Today, agriculture continues to play an important role in the local economy, although the amount of land used for agricultural purposes in the direct watershed has declined since the 1970’s; the number of farming operations has declined, while remaining farms have increased in intensity and production. PURPOSE AND SCOPE OF WORK Purpose The purpose of this project is to develop an updated watershed-based management plan (WBMP) for Unity Pond that includes EPA’s nine minimum planning elements. The project will collect information about lake water quality and watershed hydrology, inventory NPS problems, evaluate septic systems, assess the external and internal phosphorus load, and bring together a diverse group of watershed stakeholders to develop locally-supported water quality targets and watershed goals, objectives and action strategies for restoring the pond. The project will integrate project findings into an updated WBMP which will be used to guide watershed restoration efforts over the next 10-year planning period (2022- 2032). Partner Coordination, Roles and Responsibility Waldo County Soil & Water Conservation District (District) will serve as the sponsoring grantee for the project, will serve on the steering committee, will lead the agricultural and forestry survey and agricultural landowner meetings, and will work with FOLW to assist with the NPS watershed survey including writing up the watershed survey report. Friends of Lake Winnecook (FOLW) will participate on the steering committee, advertise project activities in their newsletter and provide $5,800 in cash match and $1,807 in-kind match. FOLW will lead the NPS watershed survey and the septic brochure/online septic survey, and assist CWS with in-lake assessment and the backflushing study. FOLW provide long-term plan implementation with support from other partners. The Center for Wildlife Studies (CWS) will serve as a subgrantee to assist with baseline monitoring and the backflow study at Sandy Stream, and will serve on the Technical Advisory Committee. CWS will provide $2,541 of in-kind match for the project. The Towns of Unity and Burnham will advertise project activities on their websites, serve on the project Steering Committee, and combined, will provide $3,200 in cash match. The University of Maine Cooperative Extension Service- Will assist with the agricultural land survey and serve on the technical advisory committee. A managing environmental consultant will be hired (following procurement procedures in the DEP’s NPS Grant Administrative Guidelines) to manage the overall project, complete a historical water quality analysis, develop a watershed nutrient loading model, assess the internal load and provide a management options analysis, provide technical leaders for the watershed survey, organize and facilitate SC and TAC meetings, and write the WBMP. Maine Department of Environmental Protection (Maine DEP) will administer project funding, serve as the project advisor, and provide project and technical support. DEP will play a large role in coordinating the watershed and septic survey and provide three technical leaders for the survey. The USDA/NRCS will assist the WCSWCD with the Ag survey and landowner meetings. The US Environmental Protection Agency (US EPA) will provide project funding and work plan guidance. Tasks, Schedules and Estimated Costs All press releases, outreach materials, project signs, and plans will acknowledge that the project is funded in part by the United States Environmental Protection Agency under Section 604(b) of the Clean Water Act. Project staff will consult with DEP on EPA’s public awareness terms and conditions for Section 604(b) grants before the project commences. In addition, project staff will consult with DEP and EPA before project signs are designed. Refer to the Service Contract, Rider A. Section IV. D. Acknowledgement. Task 1 – Project Administration The District will administer the project according to the service contract with DEP, prepare a subagreement with CWS, and develop an RFQ for consulting services. This task includes tracking project progress, expenses, matching funds, and submitting reports (semi-annual progress reports and final project report) and other deliverables. The district and FOLW will establish an NPS Site Tracker spreadsheet tool to efficiently accumulate and record information about NPS sites observed during this project (Task 6) to enable continued activity in future years to maintain existing BMPs and address new NPS sites.
