Tora was engaged to lead all primary environmental activities for the construction of a greenfield, state-of-the-art roofing manufacturing facility that includes a stillyard, 4-wide shingle line, recycled asphalt shingle (RAS) liquefaction equipment, and related infrastructure.

Tora evaluated sites across four states, helping the client select a location based on anticipated permitting timeframes and operational flexibility. We also provided support during facility design, including selection of air pollution control technologies. Tora developed a tracking system to manage all environmental and non-environmental permits required for both construction and long-term operations. We led all environmental permitting efforts and are currently developing the infrastructure required for plant startup, including the stormwater permit, SPCC plan, and other foundational compliance elements.

In a separate but related project, Tora professionals permitted another greenfield asphalt roofing manufacturing plant, which required a comprehensive air dispersion modeling analysis, including cumulative impact modeling to assess emissions of particulate matter and asphalt fumes against NAAQS and PSD increments.

The model incorporated dozens of emission sources, including point, volume, and area sources. A key challenge involved the state’s requirement to model all fugitive sources—including building vents, doors, haul roads, and forklift routes. To improve accuracy, Tora obtained site-specific silt loading measurements for use in AP-42 roadway emissions calculations, optimizing the final model and supporting a successful permitting outcome.
