CIPP Emissions Study - Request for Proposal
The National Association of Sewer Service Companies (NASSCO) is requesting proposals to evaluate the potential release of organic chemicals in the steam exhaust and other release points during pipe rehabilitation using the trenchless, Cured-In-Place Pipe (CIPP) method.
The work scope described on the .pdf is designed to provide a comprehensive evaluation of air emissions from steam-cured cured-in-place pipe (CIPP) installations and potential impacts on workers and the surrounding community. It calls for measurement of styrene and other organic compounds at six CIPP installation sites, representing different pipe diameters (8”, 12”, and larger), and lengths, in order to capture variation in emissions. Measurements will be conducted before, during, and after curing at the termination manhole, as well as various locations in the surrounding outside area and inside nearby buildings. Worker exposure will also be measured via personal exposure monitors. Finally, dispersion modeling will be conducted to estimate compound concentrations at a large number of locations for a wide variety of meteorological conditions. Measured and modeled concentrations will be compared to appropriate health-based action levels to determine if any potential health risks exist for workers or citizens in the surrounding community.
