CODE is managing various remedial activities at a number of KeySpan sites in New York City. The work is being conducted as part of a corporate-wide clean up program covering former utility plants and substations that are currently being closed out or renovated. To date, CODE has removed in excess of 100,000 tons of coal tar impacted soils and debris from six (6) locations for off-site thermal treatment.

At sites where new construction or facility renovation is in progress, CODE closely coordinates its excavation, handling, and removal operations with other site contractors. Soils are frequently pre-characterized so that direct loading can be accomplished. Aggressive scheduling is the norm.

The project sites are located in highly urbanized areas. Therefore, traffic control and coordination is a key work element at each location. CODE frequently conducts material load-out during off-hours to minimize the potential for exposure to neighboring communities.

In some locations, work is performed within a Sprung Structure to provide a further measure of control. CODE worked within a temporary Sprung structure on the Bayshore MGP Site project. As the project’s waste management contractor, CODE was responsible for moving empty transport vehicles in Level B Supplied Air into the Sprung structure; monitoring load-out, moving filled transport vehicles out of the Sprung structure; and preparing required paperwork for off-site transport and disposal. CODE also assisted with odor control on this project.

At the Clifton MGP Site in Staten Island CODE handled the transport and disposal of waste materials associated with KeySpan's Operable Unit No. 1 (OU-1) remedial action project. CODE worked in close coordination with other site contractors and KeySpan to ensure that the aggressive production schedule was maintained. During peak performance periods, CODE received and successfully handled up to 60,000 gallons of “mostly liquid” Jet Grout waste from Keyspan’s Jet Grout Contractor per day. CODE also participated in the design, installation, and operation of a Vapor Recovery Management System to contain and treat emissions from various phases of the Clifton MGP Site OU-1 remedial action project.

CODE provided remedial action services designed to contain lead paint chips spalling from two (2) 400 foot tall natural gas holding tanks at the Brooklyn Union Gas - KeySpan Energy site in Queens.
