EPA promulgated Effluent Guidelines for Photographic Processing in 1976. The regulation (40 CFR Part 459) covers direct discharging photo processing facilities with limitations for silver, cyanide, and pH. The Effluent Guidelines are incorporated into NPDES permits.
What is Photographic Processing?
Photographic processing is the development or printing of paper prints, slides, negatives, enlargements, movie film, and other sensitized materials. This work is performed by establishments providing the following services: portrait photography for the general public; commercial photography; commercial art or graphic design; or photo finishing. The process wastewater discharged by these facilities typically includes: 1) film and paper wash water, 2) solution make-up water and 3) area and equipment wash water.
The Photographic Effluent Guidelines regulate direct dischargers that process more than 150 square meters (1600 square feet) per day. Both commercial and goverment facilities are potentially subject to these regulations.
Guidance and Background Documents
EPA issued a guidance document in 1981 to support development of NPDES permits for photo processors; and conducted reviews of the existing regulation in 1997 and 2005.You will need Adobe Reader to view some of the files on this page. See EPA’s About PDF page to learn more.
