Industrial and commercial business have a responsibility to comply with state and federal regulations to prevent adverse environmental impacts as a result of business activities.  Pollution prevention through the implementation of Best Management Practices (BMPs) eliminates harmful pollutants from entering local waterways untreated via the storm drain system.   

Eliminating irrigation runoff protects waterways and helps your home or business save water and energy

In compliance with State storm water regulations, the City's Environmental Programs Division maintains an inventory of commercial and industrial facilities, and inspects them annually to ensure that best management practices are being used effectively. The City provides efficient service by combining storm water inspections with Sewer Pretreatment inspections for Fats, Oils, and Grease (FOG). The City is also required to notify relevant businesses of any requirements relating to the Industrial General Permit (IGP), and to notify the regional Water Quality Control Board of any businesses suspected of not enrolling in the IGP.   

Recycling and waste management programs are administered by the Recycling & Waste Reduction Division

The City inspects agricultural properties and provides educational resources to producers on how to implement best management practices. For more information and resources, visit the Agricultural Resources Ad Hoc Subcommittee webpage.

Eliminate all illicit discharges to the storm drain system, including over-irrigation.

Good Housekeeping

  • Maintain landscape and consider water wise landscaping
  • Keep outside areas swept clean. Keep absorbent material onsite and use promptly when a spill or leak occurs. Remember the spill is not removed until the absorbent has been swept up and disposed of appropriately. 
  • Use a mop and bucket only if necessary. Avoid power washing or hosing down hardscape; if needed, all wash water must be captured and properly disposed of.
  • Wash water should be prevented from entering drainage structures and from entering the street.
  • Ensure that waste lines are not connected to the storm drain system.
  • Trash and materials for recycling should be stored under cover. Dumpster lids should be kept closed and trash and recycling areas should be free of debris. Immediately replace any damaged or leaking dumpsters. Empty dumpsters before they overfill.
  • Inspect and maintain grease traps, separators, sumps, and drainage structures so that they work effectively.

Materials Handling

  • Store liquids (oils, paints etc.) under cover and provide secondary containment to capture potential spills.
  • Store all materials and equipment under cover (or provide cover before rain).
  • Ensure that containers of hazardous materials or wastes are properly labeled and stored in secondary containment under cover.
  • Have materials available to immediately stop a discharge or absorb a spill when dispensing or loading/unloading materials.

Equipment Maintenance

  • Perform maintenance work indoors if possible.
  • Promptly repair leaks and remove spills.
  • Clean equipment in designated waste areas connected to sanitary sewer.
  • Use drip pans under vehicles.
  • Store vehicles indoors where possible.


Train all employees to follow these practices. Remind them that the storm drain system is SEPARATE from the sanitary sewer and that it discharges runoff to local water bodies untreated.

If your property has structural Best Management Practices, such as bioswales or inlet filters, annual certification of maintenance is required. For more information, visit Structural BMPs page.

The Statewide General Permit for Storm Water Discharges Associated with Industrial Activities (Order 2014-0057-DWQ), known commonly as the Industrial General Permit, is issued by the State Water Resources Control Board (SWRCB). The permit went into effect July 1, 2015 and applies to a range of industries including manufacturing, recycling, transportation and landfill activities. 

Resources are available to learn about the permit and steps you can take to ensure compliance. Industrial Stormwater Compliance Workshops are offered periodically by the University of California, San Diego.

Frequently Asked Questions Regarding the IGP

Who is covered by the permit?

Facilities that require Permit coverage fall under one of the categories listed in Attachment A of the Permit. Here is an online tool to look up your SIC code.

What are the types of coverage?

1. Notice of Exclusion Certification (NEC) When your industrial activities and materials are NOT exposed to storm water Submit NEC form, checklist, and site map

2. Notice of Intent (NOI) When your industrial activities and materials are exposed to storm water Submit the NOI form, site map, storm water pollution prevention plan (SWPPP)

What do I have to do to comply?

To begin, create an account on smarts.waterboards.ca.gov. Next, register your business, upload the Permit Registration Documents (PRDs) and pay the annual fee. Check the Water Board’s website for additional requirements.

Can I reduce the costs associated with compliance?

Contact your trade organization to see if an applicable compliance group has been formed in your area. Compliance groups share resources, such as a qualified person overseeing the program and access to training, which could reduce costs to individual businesses.

What is the City’s role in this?

The City of Escondido informs local business owners of the regulation. The City is required to notify state regulators of any business operating within its jurisdiction that it believes has not obtained the coverage required by the State Industrial Permit.
