Also, each crewmember checked in with an attendant every time they entered the space. On top of this, the lead-based paint removal process was especially intense. Scaturro explains, "They had to shower and change their clothes in a decontamination trailer before leav- ing the work site each day." As with every Alpine job, safety was paramount at the The exterior abrasive blasting began in March with Pre-Tox 2000 Fast Dry sprayed over the tank's entire exterior surface to treat the lead prior to removal from the containment. The Pre-Tox mixes into the abrasive material and renders it non-hazardous for waste disposal purposes. A 20/40 coal slag blast medium was specified for use on the tank's exterior. The crew — wearing their Bullard 88 supplied-air breathing blast hoods — used 20/40 coal slag to blast the exterior steel to the NACE No. 3/SSPC-SP-6 standard for commercial blast. The blasted areas were primed with M.A.B. Ply-mastic 650 primer (mixed in a 1:1 ratio), and given an intermediate coat of the same product. The finish coat was M.A.B. Ply-thane 890HS (mixed in an 8:1 ratio), creating an exterior finish that contained two coats of epoxy and one coat of urethane. The total exterior coating thick- 92 CoatingsPro J January 2009 ness was seven to 10 mils as called for in specifications from TIC. Each coat took three days to complete. Both the primer and the finish coats were two part systems so one crew member mixed with a standard drill mixer and mixing paddle, and fed the product into the sprayer for the two crewmem- bers using Graco King 68-1 airless sprayers. The remaining two crew members helped at the top of the tank and the foreman made sure all the equipment and materials were functioning. The equip- ment was flushed at lunch and at the end of each day with MEK. Once the exterior of the tank was completed, the crew removed the abrasive material that was left to collect the overspray, from the interior of the containment with a Skid Steerer and had the antenna contractor come back and relocate the antennas before the scaffolding was removed and final cleanup of the area completed. The interior of the tank was kept out of service until the exterior was completed, so Alpine re-chlorinated the interior by spraying a chlorine solution on the interior surfaces to kill any bacteria using a 4,000 PSI power washer. The interior rigging had been removed when the interior coating was completed, so in order to reach the higher areas of the tank the crew opened the roof hatches and used 16 to 18 foot extension poles to reach the upper areas. Scaturro concludes, "We have always had a very good relation- ship with New Jersey American Water for about 15 to 20 years and with TIC for at least 10 years. While the neighborhood didn't have concerns about lead-abatement because of proper policy require- ments, they were concerned about noise. We staged equipment and used sound attenuation as much as possible to reduce the noise during the entire project." Alpine tackled the cold winter conditions as well as lead- abatement issues, confined space protocol, and noise issues to complete this project. But more than that, they insured that the citizens of Chatham, New Jersey will have safe, great-tasting water for years to come. CP
