Stormwater Management for Businesses

Businesses can help protect surface water quality by using Best Management Practices (BMPs) to reduce the amount of pollutants entering the storm drain system.
Businesses that have the potential to pollute stormwater are required under Phoenix City Code Chapter 32C to develop and implement a Stormwater Management Plan (SWMP). SWMPs identify a facility's BMPs (such as good housekeeping, chemical and waste management, and outdoor storage practices) to protect stormwater quality.

The City of Phoenix will accept Stormwater Pollution Prevention Plans (SWPPP) in lieu of a SWMP, as long as the SWPPP contains all required information.
