The following guidance pertains to reporting information on usage, discharge and off-site transfer of critical materials under the AWR Program.  Click on image for detailed information.

Part II – Section 6 of the wastewater report is addressed in this guidance:

Total Amount of the Critical Material Used In and Incidental to Your Manufacturing Processes

Section 6 – Critical Material Use Information

WHAT ARE THE ANNUAL USAGE THRESHOLDS FOR CRITICAL MATERIALS?

Minimum thresholds have been established for reporting the annual amount of each critical material used in and incidental to the manufacturing processes at a location. These annual usage thresholds have been established at either 10 pounds or 100 pounds as given in Table 1 – Register of Critical Materials (R.299.9003). You must report the amount of each critical material used in or incidental to your manufacturing processes at levels that exceed these thresholds.

PLEASE NOTE:

There are no thresholds for reporting the quantities of each critical material discharged to the waters of the state or to any sewer system. Reporting on critical materials contained in wastewater discharges must be based on actual estimates of the annual amount of each critical material released annually into the waters of the state or to any sanitary sewer system.

CM Range Code Table – The Range Code Table should be used to report the appropriate weight of critical materials reported under Section 6, 9 and 10. You must enter one of the two digit range codes in order to accurately complete the wastewater report form.
