AbTech Industries, Inc. Executes Contract for $12 Million Stormwater Systems Project in Nassau County, New York

Work on First-Of-Its-Kind Contract for Storm Water Management in U.S. to begin immediately

SCOTTSDALE, AZ – October 10, 2013 – Abtech Holdings, Inc. (OTC QB: ABHD) (the “Company”), a full-service environmental technologies and engineering firm providing innovative solutions addressing issues of water pollution and contamination to communities, industry and governments, today reported that Nassau County, Long Island, New York, fully executed a Not-To-Exceed $12 million contract with AbTech Industries, Inc., a subsidiary of the Company, for the nation’s first design-build-operate (“DBO”) storm water management project. The project, which was originally awarded July 1, 2013, addresses 10 stormwater outflow pipes in the county. Work on the project is expected to begin immediately.

The contract is structured in multiple phases. The first year of the three-year contract will involve site selection, technology selection, design and installation. The final two years of the contract will involve the operation, maintenance and water quality monitoring of the installations. The contract allows the County to extend the operation, maintenance and monitoring phases. The Company will be paid monthly progress payments for the portions of the project that are completed each month. Approximately 95% of the contract amount will be paid in the first year of the contract.

AbTech Industries will lead a team that includes its stormwater specialty firm, AEWS Engineering LLC, and regional firm Cameron Engineering LLP. AbTech will subcontract with local firms for the installation work and may also engage subcontractors for some of the other project tasks.

Commenting on the contract execution, Bjornulf White, AbTech’s EVP of Business Development said, “This first-of-its-kind DBO Stormwater management contract provides a template to proactively and effectively address the national stormwater problem through a public-private partnership model. AbTech Industries will work with and under the direction of Nassau County’s Public Works Department to assist the county in meeting its environmental compliance requirements and upgrade its stormwater outfall systems. The upgrades will be designed to address contaminants of concern such as bacteria, oils/greases, trash, debris and sediment, all of which may affect environmental and public health. In addition, AbTech plans to address flooding where necessary by designing the systems to prevent ‘reverse’ flow. These designs will utilize technology to prevent tidal storm surges from channelling stormwater upwards to streets. Nassau County is representative of several other counties on the eastern seaboard that have similar issues to address.”

Glenn Rink, CEO of AbTech, remarked, “This project in Nassau County validates our position as a stormwater solutions provider and elevates AbTech’s visibility as a full-service, water pollution treatment company.  This evolution of our business model affords us better control of the business development process and expands our addressable market, exponentially.”
