Alaska environmental reviews for the proposed West Susitna Access Project

This notice concerns environmental reviews and permits for the proposed West Susitna Access Project in Alaska, not a purchase solicitation. - Government agencies and project proponent - Alaska Department of Environmental Conservation (DEC) is reviewing AIDEA’s Clean Water Act Section 401 water-quality certification request. - U.S. Army Corps of Engineers (USACE), Alaska District, Regulatory Division (1145), Anchorage Office, is reviewing the associated Section 404 permit application, file POA-2022-00165. - Alaska Industrial Development and Export Authority (AIDEA) is the applicant and project proponent. The planned route connects near Alexander Creek to the Whiskey Bravo Airstrip and mineral exploration camp in the Matanuska-Susitna Borough. - Proposed project scope - Build an approximately 78.5-mile, two-lane gravel road, about 24 feet wide within a proposed 300-foot right-of-way. - Associated features include 10 bridges; approximately 138 culverts, including about 103 fish-passage culverts and 35 drainage culverts; 17 potential material sites; one maintenance station; one airstrip measuring approximately 200 by 5,000 feet; and nine water-extraction sites with access roads. - The application materials describe up to 700,000 cubic yards of fill in fewer than 66 acres of aquatic resources. Other project summaries cite approximately 35,079 cubic yards of fill affecting 3.18 acres of waters of the United States; these figures reflect different descriptions or accounting scopes in the materials. No compensatory mitigation is proposed, subject to agency review and determination. - Named manufacturers and design references - Acrow Bridge and Bailey Bridge modular bridge systems are mentioned as illustrative design options, not as specified purchases or selected suppliers. Alaska DOT&PF-standard precast deck bulb-tee girders are also referenced; Alaska DOT&PF is a standards agency, not an identified OEM. - Notable environmental considerations - The application and supporting plans address fish passage, drainage, wetland and water impacts, erosion and stormwater controls, stabilization, and measures to avoid and minimize impacts. No products, purchase quantities, or product part numbers are specified. - Procurement status - This is a regulatory permit and public-comment matter, not a procurement solicitation for goods or services. The construction and permit-review activities described are part of the proposed project and regulatory process.
