The campaign is being conducted in accordance with the National Pollution Discharge Elimination Systems (NPDES) Permit requirements.
Using a comprehensive, multicultural approach, the Don't Trash California campaign targets primary offenders of highway littering,
as well as the general public, to create a social mindset in California that this State does not tolerate polluting our freeways and highways.
The campaign implements proven strategies, including media advocacy, special events, partnerships, paid media and community outreach, to raise
the level of awareness of the effects of littering and encourage the public to avoid littering.
