Lead abatement system cuts corners, costs for utility company
- Pentek Inc., Coraopolis, PA (United States)
When Consolidated Edison Co. (New York) called for bids to remove lead from the 125-foot-tall steam-dispersion stacks at its Astoria Power Generating Station, the company specified that no lead could be released into the environment during the project. Another restriction was that any abrasive blasting for surface preparation would have to be accompanied by full-scale containment--including use of airtight seals, ventilation systems, entrance and exit air locks, and impermeable containment material--to ensure minimal discharge to the generating plant below the stack. Prospective contractors also would be required to meet Occupational Safety and Health Administration standards for medical surveillance, hygiene facilities, eating areas and personal protective equipment if lead levels exceeded 30 micrograms per cubic meter. To reduce the cost of erecting and maintaining full containment without jeopardizing health and safety criteria, Con Ed incorporated a practical solution to remove its aging, lead-based paint. The technology, comprised of a Vac-Pac{reg_sign} self-drumming HEPA filtration system, supports up to 10 operators using proprietary scalers and needleguns. The scalers are effective for flat areas, removing coatings at 45 square feet per hour, while the needleguns are designed for use on corners, edges, rivets and bolts.
