“Do regulatory agencies such as the EPA and OSHA publish specific guidelines for treatment and/or disposal of wastewater used in connection with a phosphatizing spray wash and pretreatment operation? This question would naturally include the organic soils, mill oils, rust inhibitors, coolants, lubricants, die release and drawing compounds.”
“The EPA establishes national limits for discharge. These may differ dramatically from your local PTOW authority. You must check with them for your actual limits of wastewater discharge. Contact your local DEP for local air and water discharge limits.
OSHA requirements are usually covered by the MSDS information for precautions on handling the chemicals. We recommend contacting your local OSHA agent for particulars.”
