FAQ: Why/ when should I call the hotline?
something that is not rain is going into a storm drain! If you see
something flowing into a storm drain or contaminating a creek and
it just doesn't look right, call the hotline. You'll be directed to
your local stormwater responder! In the past, this has included
paint, motor oil, dyed diesel, chemicals, and trash, but if you're
in doubt, please call. The hotline currently directs calls to the
best responder in Humboldt or Mendocino County.
