The Industrial General Permit was written with a clause that enabled the Permit to be modified when the new Federal Law addressing the TMDL (Total Maximum Daily Load) requirements became effective. The major concern is copper. If it is not in your inventory list, it is not an issue. However, if copper is on your site, then make certain that it is stored in a sealable barrel that is stored inside where it is not exposed to rain or run off.
This notice from the Waterboard is the first step in modifying the existing Permit. Brash Industries will respond to modifications when appropriate. Otherwise, there is nothing for you to do and we will keep you updated.
