DRAFT ENVIRONMENTAL ASSESSMENT NORTHERN BORDER REMOTE RADIO LINK PILOT PROJECT ESSEX AND ORLEANS COUNTIES, VERMONT February 2019 Lead Agency: U.S. Customs and Border Protection 24000 Avila Road, Suite 5020 Laguna Niguel, California 92677 Prepared by: Gulf South Research Corporation 8081 Innovation Park Drive Baton Rouge, Louisiana 70820 EXECUTIVE SUMMARY Background and Purpose and Need The area near the U.S./Canada International border in Vermont is extremely remote and contains dense forest and steep terrain intersected by numerous streams, lakes, and bogs. These conditions make it very difficult for U.S. Border Patrol (USBP) agents to patrol the area and communicate with each other and station personnel while on patrol. The Department of Homeland Security (DHS), Science and Technology Directorate (S&T), has developed a prototypical Remote Radio Link Project that includes the installation of a buried communications cable to enhance the communications capability and safety of Border Patrol agents who are conducting enforcement activities in these areas. U.S. Customs and Border Protection (CBP) is assisting S&T in developing this Environmental Assessment (EA) to address the proposed installation and operation of the pilot project. The purpose of this pilot project is to determine the effectiveness of this type of remote radio link system in four-season weather. The need for the project is to identify such reliable communication methods that can enhance USBP enforcement activities and agent safety. Proposed Action The Proposed Action includes the installation, operation, and maintenance of a Remote Radio Link Pilot Project along the U.S./Canada International border west of Norton, Vermont. The project consists of the installation of a buried fiber-optic communication system within the International boundary, known as the Slash. The cable is proposed to be installed using a cable plow, trenchers, rock cutters, and directional drilling equipment and would extend for approximately 7 miles westward beginning about 1.5 miles west of the Norton Port of Entry. Three existing two-track access routes currently used as skidder trails would be improved to provide project access. Equipment and material would be staged during the installation phase at the existing Sugar Barn in a disturbed area that is routinely used for logging and syrup production equipment. In addition, electrical power is available at the Sugar Barn and would be used to power the fiber optic cable. Swanton Sector Remote ES-1 Draft EA Radio Link Pilot Project February 2019 Alternatives In addition to the No Action Alternative, two action items have been carried forward for analysis. The Full Build Alternative would be implemented for the entire 7-mile corridor. The Limited Build Alternative (Preferred Alternative) would involve installation of the cable as described above, but would be shortened in length to a total of approximately 5.5 miles. That is, the cable on the western side of Line Pond would be eliminated. The shorter amount of cable would still provide valuable information regarding the efficacy of the system and data collected from the pilot project could be used in developing similar projects in other northern regions of the United States. Environmental Consequences Based on review of past investigations and the Archaeological Resources Assessment prepared for the Proposed Action, no historic properties are anticipated to be adversely affected by the cable installation. Minor and temporary effects on soils, water quality, and air quality would occur during the cable installation activities. No effects on floodplains would occur although an estimated 4.9 acres of potentially jurisdictional waters of the U.S., including wetlands, are located along the project corridor. Impacts on these resources would be avoided or minimized by the use of ground protection matting, laying weighted cable on the bottom of streams or ponds with no trenching, or by conducting directional drilling. There are no activities that require dredge or fill activities anticipated for this project. Negligible to minor impacts on vegetation communities would occur, primarily due to two-track access route clearing. Some small saplings and brush that have grown up in canopy openings may be cleared. The Slash clearing is currently maintained by the International Boundary Commission, so no additional clearing of vegetation would be required to allow for installation of the cable. Wildlife could be temporarily disturbed by the sight or noise of installation equipment. No long-term adverse impacts would be expected. Two Federally listed species, Canada lynx (Lynx canadensis) and northern long-eared bat (Myotis septentrionalis), could occur near the project corridor. Limiting the cable installation activities to daylight hours, limiting the amount of habitat disturbed, and avoiding potential roost trees that could be used by bats would minimize potential effects on these two species and result in discountable impacts. Swanton Sector Remote ES-2 Draft EA Radio Link Pilot Project February 2019 Negligible and temporary beneficial effects would occur on socioeconomic resources as sales taxes and materials purchases would slightly increase during the project installation activities. No disproportionate impacts on minority or low-income populations, or children, would occur.

  • The 2019 Breeding Status of Common Loons in Vermont

    The 2019 Breeding Status of Common Loons in Vermont

    THE 2019 BREEDING STATUS OF COMMON LOONS IN VERMONT Eric W. Hanson1,2 and Doug Morin3 ABSTRACT: The Vermont Loon Conservation Project, a program of the Vermont Center for Ecostudies and the Vermont Fish and Wildlife Department, documented 101 nesting loon pairs and 129 territorial pairs statewide. Of the 101 pairs that attempted nesting, 75 successfully hatched 115 eggs, with 87 chicks surviving through August (chick survival rate 76%, 0.67 chicks surviving per territorial pair). Six new nesting pairs and 4 new potential territorial pair were identified. Twenty-two pairs that have nested in recent years did not nest in 2019. Of 33 pairs whose first nest attempts failed, 10 re-nested, and 8 were successful. Known causes of nest failure included depredation (6 nests), flooding (13 nests), and loon disturbance (2 nests). The remaining failed nests were abandoned for unknown reasons with predators and disruption from intruder loons being the most likely causes. The causes of most chick mortality were unknown. At least 9 chicks disappeared after interactions with intruder loons, 2 were taken by Bald Eagles (Green River Res., Miles P.), and 1 chick was likely hit by a boat (Maidstone L.). During the summer months, 8 adult loon mortalities were documented. Six of these were sent to Tufts University for necropsies with 2 dying from lead fishing gear, 2 from a respiratory fungal disease, and 2 from unknown causes. We monitored several other loons reported in distress, caught in fishing line, or observed in open water holes surrounded by ice. Four loons were observed entangled in fishing line/gear, but were not observed during follow-up surveys.

    TOWNSHIPS ODDITIES AND EXTREMES Text and photography (except where noted): Matthew Farfan The following tour features fourteen attractions found in the Eastern Townships, each of which is either odd or unique in some way, or else the smallest, largest, longest, shortest, highest, or oldest of its kind. Sites range from a slave burial ground, to the highest village in Quebec, to the largest open-pit asbestos mine in the Western Hemisphere. 1) Slave Burial Ground: “Nigger Rock” & the Black Community of Saint-Armand Strong oral tradition and increasing hard evidence suggest that there was once a substantial slave community in Saint-Armand. According to tradition, a large outcrop of rock near the village, known for generations by the derogatory term “Nigger Rock,” was a burial ground for slaves two centuries ago. The "Rock" is located on what was once the property of Philip Luke, a Loyalist, who settled in the area after the American Revolution, and who, documents show, arrived with slaves he inherited from his mother. Oral tradition surrounding the site is strong among Saint-Armand's older residents, some of whom recall stories from their parents or from their childhood about the old slave burial ground or about the blacks in the area. “Nigger Rock” is believed to be the only known burial ground in Canada for blacks who were born and died in slavery. In 2003, a plaque was presented to the municipality by the Government of Quebec. It reads (in French): “Oral tradition holds that near here, at a place known as Nigger Rock, many black slaves were buried between 1794 and 1833.
