A28: R&D laboratories are subject to AWR reporting and would submit a wastewater report if they discharge a wastewater to the waters of the state or to any sewer system. There is no “de minimus” quanity for wastewater discharge under the AWR program. If the laboratory does not use a critical material in or incidental to the manufacturing or R&D processes in excess of the annual usage threshold (Table 1, R299.9003) and if there are no critical materials in the discharge other than those listed under R299.9006 (3) or (4), the facility should file an abbreviated wastewater report. An R&D facility may be exempted from reporting critical material (USE) information under R299.9004 2 (e) if exemption R299.9006 2 (i) applies.
