A person at the other facility engages in an activity mentioned in subsection 9 (1) or 27 (1) of the Act or subsection 53 (1) of the Ontario Water Resources Act and, A. uses raw materials, products or services provided by the printing facility, or B. provides raw materials, products or services to the printing facility. 3. A printing facility located in a building that contains more than one unit, at least one of which is not occupied by the printing facility. 4. A printing facility at which a person engages in, i. lithographic printing and screen printing, ii. newspaper lithographic printing and sheet-fed lithographic printing, or iii. newspaper lithographic printing and non-heatset web lithographic printing. 5. Subject to subsection (5), a printing facility at which a person engages in printing that is not digital printing, lithographic printing or screen printing. 6. A
printing facility that has more than six exhaust stacks. 7. A printing facility that has more than three noise generating equipment units. 8. A printing facility of a class identified by NAICS code 561430 (Business service centres), 812921 (Photo finishing laboratories (except one-hour)) or 812922 (One-hour photo finishing). O. Reg. 349/12, s. 3 (4).
