Written by GovTribe AI ·

EPA Region 9 awarded a single-award indefinite-delivery contract to Weston Solutions Inc. on July 11, 2019, with a ceiling value of $163.515 million for Superfund Technical Assessment & Response Team V (START V) services, expiring July 21, 2026.

This is a single-award IDIQ with no set-aside designation. The contract covers comprehensive Superfund technical assessment and response services within EPA Region 9, encompassing eight states and territories. Work includes emergency response, removal actions, site assessments, training, data management, and related hazardous substance response activities under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), Oil Pollution Act (OPA), Resource Conservation and Recovery Act (RCRA), Stafford Act, and Brownfields authorities. Place of performance is distributed across EPA Region 9 locations including California, Hawaii, Guam, American Samoa, and other Pacific territories.

The contract was awarded through full and open competition evaluated under FAR Part 15, with a base period of 12 months and six 12-month option periods extending through 84 months total.

Recent delivery orders issued under this IDIQ reflect the vehicle's broad scope. Task Order 128 ($75,000, awarded May 28, 2026) addresses monitoring and sampling for crude oil pipeline spills affecting the Los Angeles River in East Los Angeles. Task Order 126 ($64,355, awarded May 26, 2026) provides mercury assessment assistance at San Diego properties. Task Order 124 ($358,000, awarded April 16, 2026) mobilizes staff and resources to Guam and the Commonwealth of the Northern Mariana Islands for Typhoon Sinlaku emergency support under FEMA mission assignment. Additional orders include removal actions at Va'oto Lodge in San Francisco ($288,582, January 2026), engineering assessment at the Afterthought Mine NPL site ($199,509, January 2026), and a $50 million order issued January 10, 2025, supporting California wildfire response with subcontractors including South Coast Air Quality Management District, General Pacific Inc., and Davey Resource Group Inc.
