Sacramento Stormwater Laws & Regulations

The County of Sacramento has enacted a Stormwater Ordinance in order to establish minimum stormwater management requirements and controls to protect and safeguard the general health, safety, and welfare of the public residing in watersheds within this jurisdiction. The County of Sacramento is the permitting authority for all land disturbing activities and requires the land owner to maintain all on-site stormwater control facilities and all open space areas (e.g. parks or “green” areas) required by the approved stormwater control plan. The County of Sacramento will only provide construction permits to projects that establish a plan to manage stormwater runoff occurring during the construction process. The County of Sacramento, under the NPDES program, also has the authority to inspect properties for noncompliance and can issue a notice of violation (NOV) for any deficiency or infraction onsite. Property owners are responsible for the maintenance of any stormwater facilities or practices located on the property. The County of Sacramento has the authority to inspect stormwater facilities and practices in order to ascertain that they are properly maintained and functioning.

Excerpt- Sacramento Regulations

Types of Businesses Regulated

As required by the State of California, inspections are conducted at the following types of businesses:

Auto repair shops
Auto body shops
Auto sales, lease and rental facilities
Gas stations
Restaurants
Nurseries
Kennels
Equipment rental businesses
Facilities that have coverage under the State’s General Industrial Stormwater Permit.

Stormwater Quality Program BMPs

“BMPs should be considered and implemented in the above order: administrative, source control, and then treatment control. Implementing BMPs in this order is the most cost effective and does the best job of protecting stormwater quality. Administratively eliminating pollution sources will almost always be the best solution. Using source control BMPs to eliminate pollutant sources prior to polluting stormwater runoff should be your next option. Your last option is to treat stormwater runoff in an effort to remove pollutants. Treatment is likely the most expensive and often least effective way to go. Treatment control should be a part of your overall stormwater pollution prevention strategy as a last and final effort to remove pollutants that could not feasibly be addressed through administrative and source control BMPs. Treatment control BMPs should not be used as stand alone BMPs.”

Treatment Control BMPs (install and maintain):

On-site storm drain inlet protection devices, such as appropriately-selected storm drain filter inserts
Vegetative swales, sand filters, and bioretention devices
Stormwater treatment vaults
Detention basins

All treatment control BMPs require regular inspection and maintenance to ensure proper operation.

The Environmental Management Department’s (EMD) Commercial/Industrial Stormwater Compliance Program regulates certain types of businesses throughout Sacramento County and all its incorporated cities except Isleton.

The purpose of the program is to ensure compliance with Sacramento County Code (SCC 15.12) and applicable city codes which prohibit non-storm water discharge to the County’s and cities’ storm drainage system and local waters. Only storm water and a few exemptions allowed by law may be discharged into the storm drainage system.

Excerpt – Stormwater Ordinance

AN ORDINANCE REPEALING CHAPTER 15.12 AND REENACTING CHAPTER 15.12 OF TITLE 15 OF THE SACRAMENTO COUNTY CODE RELATING TO STORMWATER MANAGEMENT AND DISCHARGE CONTROL

15.12.110 Findings.

a. The Federal Clean Water Act provides for the regulation and reduction of Pollutants discharged into the Waters of the United States by extending National Pollutant Discharge Elimination System (NPDES) requirments to Stormwater and urban runoff Discharge into the County Storm Drain System.

b. The State Water Resources Control Board (“State Board”) is the State water pollution control agency for all purposes of the Clean Water Act pursuant to Section 13160 of the California Water Code. The State Board is authorized by the United States Environmental Protection Agency to administer the NPDES program within the State. The Portr-Cologne Water Quality Control Act (Water Code section 13000 et seq.) provides authority for the State NPDES program, including provisions to issue NPDES Permits and Waste Discharge Requirements to regulate discharges of Stormwater to waters of the State.

c. Stormwater flows from individual properties to the County Storm Drain System and then ultimately to the waters of the State.

d. The County is a co-permittee under the Waste Discharge Requirements for County of Sacramento, Cities of Sacramento, Citrus Heights, Elk Grove, Folsom, Galt, and Rancho Cordova Area-Wide Storm Water Discharges From Municipal Separate Storm Sewer Systems Sacramento County (Order No. R5-2002-0206), dated December 6, 2002, which also serves as a National Pollutant Discharge Elimination System Permit under the Federal Clean Water Act (NPDES No. CAS082597). As a co-permittee, the County is required to possess the necessary legal authority, and to implement appropriate procedures, to regulate the entry of Pollutants and Non-Stormwater Discharges into and fromthe County Storm Drain System.

e. The County’s Municipal Stormwater Permit requires the County effectively to prohibit Non-Stormwater Discharges from the unincorporated urbanized area of the -2- County into the County Storm Drain System except as otherwise permitted by Federal law.

f. Non-Stormwater Discharges and Stormwater Pollutants that are discharged directly to waters of the State without passing through the County Storm Drain System are not subject to the requirements of the Municipal Stormwater Permit. However, such discharges have the potential to degrade water quality and impact the quality of life for the people of the County. Regulation of such discharges by the County provides benefits to its people and protects the local environment.

g. The Board finds in this regard that the provisions of this Chapter are necessary to provide the County with the legal authority necessary to implement and otherwise comply with the requirements of its Municipal Stormwater Permit and to protect the waters of the State for the benefit of its people and the environment.
