Storm water runoff is carried by the storm water system (gutters, storm drains and ditches) to local waterways, and is a major source of pollutants. This runoff can significantly contribute to localized violations of water quality standards for specific pollutants during storms. While much of the storm-generated pollution is from street runoff, construction activities can also be a major source.
The State Water Resources Control Board (SWRCB) issues two state-wide general permits to cover a variety of industrial and construction activities. The general permit requires:
Most Sonoma County businesses that are regulated by the storm water runoff requirements register for coverage under one of two classes of general permits. This is true of both existing businesses and new businesses.
Yes, if your business has an Standard Industrial Code (SIC) specified in the storm water regulations. Contact the appropriate RWQCB to find out if your business is on the mandatory filing list.
Yes, if your business falls into one of the following categories and is not exempted.
Exceptions to the general industrial permit requirements:
As the applicant, you have the responsibility to determine if you are covered by the regulations and required to file for either individual or general storm water permits. Contact the local RWQCB office staff for help in making your determination whether to file for a permit.
The RWQCB will help you determine if you are covered and how to comply. Full permit forms and instructions are available from them. Other help and information from the state can be obtained from the California Office of Permit Assistance and the Business Environmental Assistance Center (BEAC).
File your Notice of Intent with the State Water Resources Control Board (SWRCB) in Sacramento and comply with the general permit conditions through either the North Coast Regional Water Quality Control Board (NCRWQCB) or the San Francisco Bay Regional Water Quality Control Board (SFBRWQCB). If you are unsure which district your project is in, contact either office for help.
NCRWQCB: Russian River drainage basin and coastal areas
SFBRWQCB: Petaluma and Sonoma valleys.
Exception: Businesses within the City of Santa Rosa still need to file a Notice of Intent with the SWRCB, but must work with the city in complying with general permit conditions. The city is the enforcing body for industrial and construction activities within Santa Rosa city limits.
If you decide not to file for a permit, then you must prepare documentation supporting your decision. Adequate documentation may include implementing many of the requirements of a Storm Water Pollution Prevention Plan (SWPPP) to demonstrate that all runoff from your site has been assessed and controlled.
You do not need to provide this file to the RWQCB, but if questions or problems arise later, you are required to disclose the documentation on which you based your decision not to get a permit. If you believe a reasonable chance exists that you should get a permit and you do not, significant penalties and other enforcement action may be taken. Do the work to make sure your decision is correct and prepare the documentation to back it up. See Enforcement Provisions and Penalties and Your Rights.
NOTE: The SWPPP must be kept at the business site and provided upon request to RWQCB staff and/or local agency.
* Some businesses may be exempt from sampling and analysis requirements only — but not all monitoring requirements — if they meet specific requirements. Contact your RWQCB to find out if you qualify. A strong effort to eliminate exposure of any industrial activities to storm water and to prepare an effective SWPPP may spare you the costs of sampling and laboratory analysis.
If you are not satisfied with the results of a decision regarding storm water permitting and compliance, you may appeal by following these steps in the order shown:
Application and annual fees for construction storm water discharges under a general NPDES storm water permit are $500, payable to the State Water Resources Control Board. If you are discharging to the Santa Rosa municipal storm water system, you may only have to pay an application fee and an annual fee thereafter of $250 to the State Water Resources Control Board. Additional fees may be charged by the City of Santa Rosa.
Note: If you already have a permit issued by the Regional Board, no fee is required to be filed with your NOI (Notice of Intent), but you still must submit the application and comply with regulations.
Civil fines of up to $25,000 per day per violation can be imposed by the RWQCB, along with other civil penalties. Other state and local agencies can impose additional fines and penalties for violations of California Fish and Game codes, local ordinances regarding fair business practices, etc. In extreme cases, criminal penalties can also be pursued.
Caution: The magnitude of penalties can be affected by mitigating factors. These can include such issues as whether the business knowingly violated or willfully evaded the intent of the law. Your best interests lie in knowing exactly what is required of your business by getting the specific information you need from your Regional Water Quality Control Board.
