Commercial Agriculture Businesses
Common materials from Commercial Agriculture Businesses, such as fertilizers, metals, leaf litter, oil, and grease, are considered pollutants that can harm water quality if they make their way into storm drain systems. These pollutants can degrade water quality and kill aquatic organisms if they wash into our waters.
All sources of pollution are prohibited from leaving your site and entering streets and storm drains. Use the resources below to protect our waterways and keep your business in compliance.
What can I do?
Use Best Management Practices (BMPs)!
BMPs are techniques or controls used to prevent or reduce the discharge of pollutants, such as fertilizers, pesticides, and organic wastes, into the stormwater conveyance system (storm drain system). The helpful documents below, and the Guidance Handbook to Reduce Water Pollution, are references to help reduce pollutants to our storm drain system and local waterways
