Dear Ms. Walker:

This letter is in response to the application you submitted to the U.S. Army Corps of Engineers (USACE), New England District on October 2, 2025, for a Department of the Army general permit verification. We have assigned this project file number NAE-2025- 02189, which you should reference in all correspondence with this office. This letter follows a provisional notification letter from this office, dated October 24, 2025.

A review of the information provided indicates the proposed work includes the permanent discharge of fill material within 2,368 square feet below the Ordinary High Water (OHW) mark of the Housatonic River associated with the replacement of the bridge conveying Division Street over the Housatonic River, at Latitude 42.231730º and Longitude -73.354840º, in Great Barrington, Berkshire County, Massachusetts. The existing abutments will be cut down and retained. Rip-rap scour protection overtopped with natural streambed material will be installed in front of the abutments. The work is shown on the enclosed plans titled “MASSACHUSETTS DEPARTMENT OF

TRANSPORTATION HIGHWAY DIVISION PLAN AND PROFILE OF DIVISION

STREET (BRIDGE NO. G-11-002 (04F)) IN THE TOWN OF GREAT BARRINGTON,”

on 21 sheets dated 9/4/2025 (sheets 18 and 19 dated Revised 11/19/2025).

Based on the information you have provided, we verify that the activity is authorized under General Permit 23 of the June 2, 2023, federal permit known as the Massachusetts General Permits (GPs). If the extent of the project area and/or nature of the authorized impacts to waters are modified, a revised application must be submitted to this office for written approval before work is initiated. You can find a copy of these permits at: https://www.nae.usace.army.mil/Missions/Regulatory/State-General- Permits/.

Any deviation from the terms and conditions of the permit, or your submitted plans, may subject the permittee to the enforcement provisions of our regulations. Therefore, in the event changes to this project are contemplated, it is recommended you coordinate with this office prior to proceeding with the work. This office must approve

RE: 401 WATER QUALITY CERTIFICATION

BRP WW 11, Minor Fill Project

BRP WW 08, Minor Dredge Division Street Bridge G-11-002 (04F) replacement over the Housatonic River Great Barrington, MA

401 WQC Filing Number: 25-WW26-0024-APP

USACE Application No. NAE-2025-02189 MassDOT File Number: 612183

Dear Ms. Walker:

The Massachusetts Department of Environmental Protection (MassDEP) has reviewed your application for a Water Quality Certification (WQC), as referenced above. The WQC application was deemed complete on December 12, 2025. In accordance with the provisions of MGL Ch. 21, §§26-53 and Section 401 of the Federal Clean Water Act as amended (33 U.S.C. §1251 et seq.), it has been determined there is reasonable assurance the proposed project will be conducted in a manner which will not violate applicable water quality standards (314 CMR 4.00) and other applicable requirements of state law.

The project proposes the replacement of the existing, temporary bridge (G-11-002 (04F)) superstructure over the Housatonic River, as well as improvements to the existing roadway approaches and minor stormwater improvements in Great Barrington (the Project).

Proposed work includes riprap scour protection which will be installed around the existing abutments.

A00831 - 29

The Commonwealth of Massachusetts Department of Environmental Protection

Address: 100 Cambridge Street, Suite 900, Boston, MA 02114 Phone: 617-292-5500

The original bridge, constructed in 1950, consisted of a single-span structure with an overall bridge span of 136.5 feet and width of 25 feet. This bridge carried two 10-foot travel lanes with no shoulders. The original bridge was closed to vehicular traffic in 2019 due to structural deficiencies and the current temporary structure was installed in November of 2022. The temporary bridge is a single-span structure with a length of 140 feet and a width of 26 feet-10 inches. The temporary bridge carries one lane of alternating traffic and a 5-foot sidewalk. Division Street is a two-lane, uncurbed road with two 11-foot travel lanes and no shoulders or sidewalks.

The Project will occur within Priority Habitat of several state-listed species. Accordingly, the Natural Heritage & Endangered Species Program of the MA Division of Fisheries and Wildlife (NH&ESP) has determined that, in order to avoid a prohibited take of state-listed species, the conditions outlined in the NH&ESP letter of October 10, 2025 shall be met. This includes a prohibition of in-water work between April 1st and July 15th. While the Housatonic River as a whole is considered a cold water fishery, the MA Division of Fisheries and Wildlife has stated that this particular location is not known for supporting cold water fish.

The Project will occur within a Federal Emergency Management Agency (FEMA) 1% annual chance of flooding zone (Zone AE) associated with the Housatonic River but will not impact the Base Flood Elevation or regulatory floodway. Though TMDLs have not been established for this segment of the Housatonic River, it is listed as a Category 5 waterway in the Integrated List of Waters as a result of impairment due to the presence of the invasive zebra mussel (Dreissena polymorpha) and elevated concentrations of PCBs (polychlorinated biphenyls) in fish tissue.

The Project will replace the existing temporary bridge with a new 136.5-foot single-span structure consisting of steel plate girders with a composite concrete deck. The new bridge width will be 32 feet consisting of two 11-foot travel lanes, one in each direction, and 5-foot shoulders on both sides. The existing abutments will be cut down, recapped, and reutilized with the construction of the new superstructure. These abutments will have riprap scour protection installed around them. 330 feet of full depth reconstruction of the approaches will occur, with approximately 160 feet on the east side of the bridge and 170 feet on the west side. During the course of project review, the proposed quantity of riprap to be installed was decreased while the quantity of proposed natural streambed material to be installed was increased.

A00831 - 30

In total, 2,368 square feet (sf) of permanent impact to Land Under Water (LUW) is required to complete the project. Permanent impacts are due to the placement of riprap scour countermeasures surrounding the existing bridge abutments.

Installation of riprap scour protection will require dredging of approximately 674 cubic yards (cy) of material. The Project area is known to have high levels of PCBs which was corroborated by soil samples taken in April of 2025. These samples also revealed low levels of heavy metals just below the RCS-1 limit. Proper handling, containment, dewatering and transportation of this material will be conducted throughout the duration of the project.

An alternatives analysis was completed in accordance with 314 CMR 9.00. Three alternatives were considered, and the chosen alternative was picked to minimize impacts to the Housatonic River. The no-build alternative is not practicable to meet the project goal of removing the temporary bridge superstructure.

The Project meets the Stormwater Management Standards to the maximum extent practicable (MEP) per 314 CMR 9.06(6). The installation of the pathways and hardscapes at the approaches will increase impervious surface within the Project limits by 3,205 sf.

The proposed stormwater improvements include four additional deep sump catch basins placed along the northern and southern edges of the western approach. The proposed catch basins will connect into the existing closed drainage system, discharging to the Housatonic River. Additionally, the two catch basins installed along the southern edge of the roadway will discharge stormwater to two proposed leaching basins, which will be installed along the southern edge of the western approach. Additional stormwater control measures (SCMs) were not proposed due to steep slopes and the presence of Article 97 property in close proximity to the project limits.

The Project will comply with the Stream Crossing Standards to the maximum extent practicable. All standards will be met except for Standard 3. Bankfull width of the Housatonic River is 152 feet, requiring a span of 182 feet to satisfy 1.2 times bankfull width. The current span of 134 feet will not change because the existing abutments will be utilized for the proposed bridge.

Based on a review of information provided by the applicant, MassDEP finds that this project complies with the standards described under 314 CMR 9.06. Public notice was

A00831 - 31 provided in the Berkshire Eagle on October 3, 2025. No comment letters were received during the public comment period.

Therefore, based on information currently in the record, MassDEP grants a WQC for this project subject to the following conditions to maintain water quality, to minimize impact on waters and wetlands, and to ensure compliance with appropriate state law. MassDEP further certifies in accordance with 314 CMR 9.00 that there is reasonable assurance the project or activity will be conducted in a manner which will not violate applicable water quality standards (314 CMR 4.00) and other applicable requirements of state law. Finally, the Department has determined that upon satisfying the conditions and mitigation requirements of this approval, the project provides a level of water quality necessary to protect existing uses and accordingly finds that the project to be implemented satisfies the Surface Water Quality Standards at 314 CMR 4.00. This WQC is for all federal permits and licenses, including the U.S. Coast Guard Bridge Permit, pursuant to 40 CFR Part 121.

Pursuant to 314 CMR 9.09(1)(d); 314 CMR 9.06(6)(a); 310 CMR 9.06(2); 314 CMR 9.07; 314 CMR 9.07(1); 314 CMR 9.09(7)(5)(c); 314 CMR 9.11; and 314 CMR 9.09(1)(e), the following Special Conditions are necessary to ensure that construction practices and stormwater controls are implemented in such a manner as to prevent degradation to wetlands and waters; ensure that practicable steps have been taken which will avoid and minimize impacts to wetlands and waters; minimize turbidity and sediment caused by construction activities; ensure that water quality is not degraded, and that biology of the waters are not negatively impacted by potential discharges; and/or maintain a record of the dredged material for reference and to ensure accountability in its transportation.
