CASQA develops and publishes Best Management Practices (BMP) Handbooks for use by organizations to be in compliance with stormwater permits. Online subscriptions, including SWPPP templates, are available for the Construction, Development, and Industrial & Commercial BMP Handbooks.

Water Quality Priorities

Four clear statewide water quality priorities have been identified: Pathogen Indicators (e.g., Bacteria), Biological Integrity / Biostimulatory Substances; Current Use Pesticides, and Trash. CASQA has prioritized developing solutions for each of these water quality priorities.

Our Water, Our World (OWOW)

This award-winning partnership is an excellent opportunity to educate the public and reduce toxicity in waterways from current use pesticides. Several municipalities utilize OWOW as a cost-efficient way to meet permit requirements.
