The City of Covina's stormwater pollution prevention program is governed by various federal, state and local laws and regulations.
The Clean Water Act of 1987 established requirements for storm water discharges under the National Pollution Discharge Elimination System (NPDES) permit program. The goals of the permit include protecting the beneficial uses of the water bodies and reducing stormwater pollution.
Polluted stormwater degrades our creeks and ocean. Sediments cloud the water, nutrients promote the growth of algae and toxic chemicals from pesticides or leaking cars all threaten the health of fish and other aquatic life. Bacteria and parasites from pet waste and leaking septic tanks can make our ocean unsafe for swimming and surfing.
