415.11.1.1.1 Aggregate quantities.
BC § 415.11.1.1.1
The aggregate quantities of hazardous materials stored and used in a single fabrication area shall not exceed the quantities set forth in Table 415.11.1.1.1. Exception: The quantity limitations for any hazard category in Table 415.11.1.1.1 shall not apply where the fabrication area contains quantities of hazardous materials not exceeding the maximum allowable quantities per control area established by Tables 307.1(1) and 307.1(2).
