Design of proper containment requires the participation of specialists in structural engi­neering, coatings, ventilation, and exhaust. The following considerations should be addressed in the development of a containment system: • The environmental media (air, water, soil) that are vulnerable and the containment methods that will provide the best protection • Durability • Compatibility with the […]

K. A. Trimbler has described and compared methods of lead paint removal. His findings are summarized in Table 1.15 and described below. (K. A. Trimbler, Industrial Lead Paint Removal Handbook, 2d ed., Steel Structures Painting Council/KTA-Tator, Inc., Pittsburgh, 1993, and personal communication, August 2002.) Quality of preparation Debris created Rust/mill Equipment investment" Paint removal^ scale […]

Workers involved in removal, containment, and handling of lead-based paint must be pro­tected against lead hazards. Blood poisoning has historically been a serious job hazard dur­ing bridge painting and likewise dangerous during the removal of lead-based paint. In addition, enclosing the work area to capture the blasting grit and waste paint creates a con­fined area […]

A number of methods have been advanced to effectively contain blasting debris and to min­imize the amount of waste generated from the management of lead-based paint from steel bridges. These methods are discussed in Art. 1.5.5 of this chapter. They can be broadly characterized as follows. Deferring Maintenance. This approach does not serve to protect […]

Hazardous waste is regulated under the RCRA if more than 220 lb (100 kg) of hazardous waste is generated each month, as is the case in most bridge paint removal projects. RCRA defines the concentrations of a waste that should be considered hazardous and establishes procedures for handling and disposing of hazardous waste. Disposing of […]

A bioaccumulative substance such as lead can be stored in various organs and tissues of the body. As lead-containing tissues are consumed by larger organisms in the food chain, a cumulative effect occurs in each subsequent organism. For example, a fish in a lead-contaminated environment may be exposed to lead in the water and in […]

A significant number of state-maintained steel bridges are coated with lead-based paint. Steel bridges were coated with lead-based paint for more than 40 years. The coating sys­tems have an expected effective life of 15 to 25 years, and those on many bridges are now deteriorating. Life extension and overall protection of the bridges from corrosion […]

Title VI of the Civil Rights Act of1964 (42 USC 2000d et seq.). The Civil Rights Act of 1964 was arguably the most instrumental piece of legislation in providing an opportunity voice for minorities to participate in the review of federal capital programs. The Act pro­hibits discrimination on the basis of race, color, and national […]

National Historic Preservation Act (NHPA). The purpose of the NHPA is to protect the historical and cultural foundations of the nation. The NHPA created the Advisory Council on Historic Preservation (ACHP) and provides for the review of federal projects that may affect a significant historic site. Section 106 of the NHPA requires all federal agencies […]

Farmland Protection Policy Act (FPPA). The Farmland Protection Policy Act of 1981 (73 USC §4201 et seq.) requires that a federal agency evaluate the effects a project may have on prime farmland before that agency can approve any action that may result in the conversion of farmland from agricultural use to nonagricultural use. The FFPA […]
