联邦能源管理委员会 不。 P-3181. 豁免 issued September 17, 1981.

The Hailesboro No. 6 Project (FERC No. 3181) is located on the Oswegatchie River in St. Lawrence County, New York. The 132-mile long Oswegatchie River is located in the St. Lawrence River watershed. The 源头 of the Oswegatchie River are in the Adirondack Mountains and the river flows generally to the west and then north before flowing into the St. Lawrence River in Ogdensburg, New York.

The project is located at river mile (RM) 68.2 and is the 8th 坝 upstream from the mouth, and the most upstream of three associated projects that also include Hailesboro No. 4 (LIHI #198) 和 Hailesboro No. 3 (LIHI #197). The river is split into three branches upstream (Island Branch) and between the Projects that recombine downstream of Hailesboro No. 3.

The project was originally constructed around 1930 and operates under an 豁免 issued by the Federal Energy Regulatory Commission on September 17, 1981.

The project consists of:

  • a 10-foot-high and 150-foot-long reinforced concrete gravity overflow-type dam with a crest elevation of 487 ft National Geodetic Vertical Datum (NGVD);
  • a reservoir with a surface area of 4 acres and negligible storage capacity at normal surface elevation of 487 feet NGVD that creates a short bypassed reach approximately 420 feet long;
  • a 40-foot-wide and 70-foot-long intake structure with 门 and trashracks along the south (left) bank;
  • a 发电站 containing two turbines connected to two generators with a combined capacity of 900 kW;
  • a short tailrace discharging to the Hailesboro No. 4 impoundment;
  • electrical switchgear, a 75-foot-long 2.3-kilovolt (kV) transmission line, and appurtenant facilities.

The Project operates in a 径流 mode with inflow approximating outflow and minimal fluctuations in impoundment water surface elevation. 扣押 water spills into the bypassed reach under normal most operating conditions via a notch in the dam. There are no recommendations or requirements for a minimum flow in the bypassed reach which is short and bedrock-based with little aquatic habitat.

The Oswegatchie River in the vicinity of the project is designated as Class A water. The best usages of Class A waters are as a source of water supply for drinking, culinary or food processing purposes, primary and secondary contact recreation, and fishing. The project reaches are not listed as impaired by NY Department of Environmental Conservation (NYSDEC) and run-of-river operations do not affect water quality.

There are no migratory fish in the project reaches due to the presence of several downstream dams as well as natural falls that block upstream fish movement. Resident fisheries of the Oswegatchie River in the Project vicinity consist of a mix of warm and cool water species. The most abundant species captured during the surveys were rock bass, fallfish, and pumpkinseed. The low intake approach velocity of 1.66 ft/second allows most fish to avoid 夹带 in the turbines. In addition, many smaller fish that might not be able to outswim the approach velocities are often small enough to avoid turbine blade strikes and pass through a powerhouse unharmed.

Project lands encompass about 4 acres for the impoundment and a negligible amount of land surrounding the facility. There are no lands of ecological significance and no critical habitats located in the vicinity. The run-of-river operations limit fluctuations in impoundment water surface elevation that otherwise could contribute to shoreline erosion.

The only threatened or endangered species that could be present in the project vicinity is the Northern long-eared bat. Several migratory birds may be present in the Project areas and include belted kingfisher, black-billed cuckoo, chimney swift, golden-winged warbler, and wood thrush. The project’s small footprint and lack of need to cut trees limit any potential impacts to sensitive species.

There are no known aboveground or archaeological resources listed in or eligible for listing in the 国家历史遗迹名录 in the Project area. No traditional cultural properties have been identified. However, due to the age of the dam and powerhouse, it is possible that they could be eligible for listing, subject to determination of historical relevance.

There are no recreation facilities or public access locations at the impoundment. The bypassed reach is short and contains no recreation facilities or access locations, as the area is surrounded by forested private property which limits access. Recreational access is available upstream in the Fowler Project’s (FERC No. 6059) downstream reach, and just downstream of the project in the Hailesboro No. 4 impoundment.

2023 年 5 月 4 日： The Low Impact Hydropower Institute has preliminarily approved Low Impact Certification for the Hailesboro No. 3, No. 4 and No. 6 Hydroelectric Projects. The full application and reviewer’s report are available below. This decision is preliminary pending the 30-day appeal window. Only those who commented on the initial applications during the 60-day comment period are eligible to file an appeal. Such appeal needs to include an explanation as to how the Projects do not meet the LIHI criteria. Appeal requests can be submitted by email to comments@lowimpacthydro.org with “Hailesboro Projects” in the subject line, or by mail addressed to the Low Impact Hydropower Institute, 1167 Massachusetts Ave, Arlington, MA 02476. All requests will be posted to the website. The applicant will have an opportunity to respond and any response will also be posted. 请求必须在 2023 年 6 月 3 日东部时间下午 5 点之前收到。

February 7, 2023: The Low Impact Hydropower Institute has received a complete application for Low Impact Certification of the Hailesboro No. 3, 4, & 6 Hydroelectric Project.  LIHI is seeking public comment on this application.  Specifically, we are interested in knowing whether you think the Project meets the LIHI Low Impact Certification Criteria, as revised in the 2nd Edition Handbook.  Please review the program and criteria in LIHI’s revised 手册 然后查看以下项目的申请材料。与特定 LIHI 标准（流量、水质、 鱼道等）将非常有帮助，但所有评论都会被考虑。评论可以通过电子邮件提交给研究所 comments@lowimpacthydro.org with “Hailesboro 3, 4, & 6 Project Comments” in the subject line, or by mail addressed to the Low Impact Hydropower Institute, 1167 Massachusetts Avenue, Arlington, MA 02476.
