Kodak does not recommend the use of septic systems for disposal of photographic processing chemicals because the disposal of photographic processing solutions may affect the proper operations of the septic system. Septic tank systems are used for the disposal of domestic waste, primarily in areas where municipal sewers are unavailable. Therefore, they are engineered for that stated purpose, and operate with anaerobic (in the absence of oxygen) biological action to accomplish the treatment of discharged wastes.
Discharge from septic tank systems may adversely affect sources of underground drinking water. Regulations have been established by the federal Environmental Protection Agency (EPA) and many states to minimize that potential. Your U.S. EPA Regional or State Administrator of the Underground Injection Control (UIC) Program and/or local health department should be contacted to determine whether the discharge of photoprocessing effluents into your septic system is allowable. Due to increased enforcement on disposal to Class V injection wells which include septic tanks, thorough inquiry on the regional, state or local compliance requirements is advised.
Other disposal options for your photoprocessing waste include household hazardous waste collection facilities in your area, discharge to a nearby municipal wastewater treatment plant, or a licensed chemical hauler. Household hazardous waste collection facilities are options only if you generate less than 100 kilograms (220 pounds) of hazardous waste per calendar month.
Customers who use KODAK photographic chemicals can also arrange to have their wastes properly treated and disposed of by using the KODAK RELAY Program.
