The following procedures are required of all dark room operations
to ensure compliance with federal, state, and local environmental
regulations.
- Spent fixer must be collected from all photo processing operations
for on-site silver-recovery prior to being discharged to the
sewer.
EMP manages a campus silver recovery unit, and will collect your
fixer for treatment. Spent Developer may be discharged down drains.
Developer may not be mixed with fixer as this will cause damage
to the silver recovery unit.
- Spent fixer should be collected in appropriate containers.
No
more than 55 gallons of spent fixer should be accumulated at
your
dark room. If smaller (15 gallon) containers would be
sufficient, these are preferred.
The EMP will remove fixer containers when they are full. Call 2-3477
to arrange a pick-up, or use the
online form. |
