The National Organic Program (NOP) recently announced an important clarification to the use of chlorine in organic production systems. This may require operational changes for some CCOF clients who use chlorine for postharvest washing of crops. The NOP now requires that a potable water rinse follows chlorine used in postharvest water at more than 4 parts per million (ppm). CCOF was previously able to approve the use of chlorine at levels above 4 ppm in postharvest usage because of industry confusion over the meaning of the word "residual" in the regulations.
