Source Control

The Source Control Inspector will ensure that businesses are in compliance with the City's Sewer Use Ordinance while providing an increased availability of environmental awareness and information at the community, business and school levels.

The Source Control Program is a pollution prevention program consisting of the following two components:

Source Control
Stormwater Pollution Prevention

The Source Control Program helps to protect the environment, the wastewater treatment plant, the City's facilities and personnel, and the community from adverse effects due to improper waste discharges.

The Stormwater Pollution Prevention Program ensures the future health, safety and general welfare of Daly City citizens by protecting and enhancing water quality of our watercourses, water bodies, and wetlands in a manner pursuant and consistent with the Clean Water Act.
The first federal pretreatment regulations were established in 1972 under the Clean Water Act. This regulation set forth pretreatment standards for the protection of the wastewater treatment plant. Since then, the USEPA http://www.epa.gov/ow/ developed the General Pretreatment Regulations which established mechanisms and procedures for use by state and local pretreatment programs to protect the environment and local communities.
The objectives of the General Pretreatment Regulations (40 CFR 403) are to:
Prevent pollutants that will interfere with the operation of the plant
Prevent pollutants that will pass through the plant untreated
Improve opportunities to reclaim and recycle wastewater
Reduce the health and environment risks of pollution
Although the City is not required to have an approved pretreatment program the RWQCB requires the City to have an inspection program to ensure that businesses comply with these standards.
What the program is
The Inspection Program is a program that enforces businesses and potential businesses to comply with the North San Mateo County Sewer Ordinance. The Sewer Ordinance is a set of rules and requirements that comply with all applicable state and federal laws required by the Clean Water Act. Select businesses such as restaurants, auto repair and body shops, dental practices and photo labs are types of businesses that have the potential to damage the wastewater treatment system and environment.
Discharge Compliance and Enforcement
The Source Control Inspector is responsible for enforcement of the Sewer Ordinance. Enforcement will occur in the form of letters and informal violation notices exerting increasing pressure to comply. If a good faith effort to comply is not witnessed, citation will occur. It is the policy of this program that education be the primary means used to gain compliance.
From January 1, 2000 to May 1, 2000, the Source Control Inspector inspected 113 businesses. To date, all 113 businesses are in compliance with the Sewer Ordinance.
In 1989, Congress passed amendments to the Clean Water Act requiring States to address the increasing problem of runoff pollution into storm drains, which carry water directly into nearby waterways, untreated. The State began requiring an NPDES (National Pollutant Discharge Elimination System) permit for stormwater discharges, also called non-point source discharges. To save costs and share information, all the cities in San Mateo County and the County together formed the San Mateo Countywide Stormwater Pollution Prevention Program or STOPPP. Each municipality shares in general program tasks but must maintain a stormwater pollution prevention program.
The San Mateo Countywide Pollution Prevention Program (STOPPP) developed its own Stormwater Management Plan consisting of five major pollution prevention and control sections.
Municipal Maintenance Activities
Industrial and Illicit Discharge Controls
Public Information/Participation
New Development and Construction Controls
Watershed and Monitoring

Each of the Plan's sections describes goals, existing conditions, and tasks that will be accomplished over a five-year period.
  Municipal Maintenance Activities (Back to Program Menu|Back to top)
The efforts by our Daly City Streets staff make a big difference in protecting the quality of our waters. Municipal Maintenance activities reduce the pollutant load into our waterways through street sweeping, cleaning catch basins and storm lines, and removing material from drainage channels. In 1999, over 20,000 miles of streets were swept. That's the distance of the circumference of the earth at this latitude! With that and the 194 catch basins cleaned, there were 2,000 cubic yards less litter and waste material entering the Bay and Ocean. The Streets Division of the Public Works Department currently performs these activities. Contact Russ Ranson at 650-991-8097 or Email: rranson@dalycity.org to report a plugged storm drain or debris filled catch basin.
Another part of the Municipal Maintenance component is the collection and recycling of materials and waste. Contact Allied Waste Services at 650-756-1130 or Email: www.alliedwastedalycity.com for non-hazardous recyclables and the San Mateo County Household Hazardous Waste Program at 650-363-4718 for hazardous recyclables and waste.
Industrial and Illicit Discharge Controls (Back to Program Menu|Back to top)
Illicit discharges are releases of pollutants or non-stormwater to the storm drain system. Source Control and the Streets Division staff respond to calls from the public or incidents discovered in the field. If the discharger is seen, they are educated about their pollution contribution and asked to clean up the material they illegally discharged, if possible. Sometimes they are given a warning notice of violation. Some occasions warrant citation. The Streets Division may be able to clean up the material if it is still on the street or if it was captured in the catch basin. Cost recovery by the discharger is pursued if appropriate. Many times, it's simply too late and the material enters our waterways.

If the discharger is not present or known, door hangers are left in a neighborhood to educate area residents and encourage area reporting in the future. Illicit discharges occur by both businesses and residents.

We discovered 70 illicit discharges in 1999. Businesses accounted for 74% of the discharges, residents 23% and 3% were unknown. How many others occurred that we never knew about is why pollution education efforts are so important! To report an illicit discharge to the storm drain, contact the Department of Water and Wastewater Resources at 650-991-8200.

Inspections are continuing to help our local businesses understand how their actions affect our water quality. Many businesses have expressed their support of the program. The added benefit of stormwater inspections is a cleaner community, as cleanups are routinely requested as part of the enforcement process. This goes for litter as well as more toxic pollutants such as used motor oil. In 1999, 190 inspections were performed with 36 cleanups completed.
  Public Information/Participation (Back to Program Menu|Back to top)
Public Information and Participation is one of the keys to preventing stormwater pollution. The better everyone understands what causes stormwater pollution and the simple things that we can do about it, the cleaner our bay and ocean will be. The Source Control Inspector conducts educational outreach activities to convey general information about stormwater pollution problems and solutions. These activities include developing and distributing informational flyers and promotional materials, working with schools, stenciling storm drain inlets, and participating in the San Mateo County Fair. For more information on pollution prevention, contact Ward Donnelly at 991-8208 or Email: wdonnelly@dalycity.org
New Development and Construction Controls (Back to Program Menu|Back to top)
The new development of the stormwater program addresses pollution during construction projects including sediment and erosion control, as well as incorporating permanent controls into project designs. The Daly City Specifications and the General Conditions of Approval, which apply to all projects, contain language requiring stormwater pollution prevention practices.

Contractors are being informed of the Best Management Practices (BMPs) required on all construction projects. Contractors are now required to address stormwater pollution controls through the Engineering permit process prior to project commencement. For more information on New Development and Construction Controls contact Tatum Mothershead at 991-8159 or Email: tmothershead@dalycity.org
Watershed and Monitoring (Back to Program Menu|Back to top)

The Watershed and Monitoring component of the stormwater plan conducts special studies to determine which prevention techniques work best and where to focus our pollution prevention efforts.

What's a watershed? A watershed is that area of land that would drain rainwater to a particular waterway based on topography. The amount of imperviousness in a watershed is important because once it approaches 40%, the receiving waterway starts to show significant degradation. By finding out which watersheds can still be "saved", agencies can focus planning efforts appropriately. Daly City lies in three major watersheds:

Vista Grande
Colma Creek
A study conducted in 1998 looked at the amount of impervious (paved) surface that exists in different watersheds in the County. Colma Creek, which extends from Pointe Pacific and part of San Bruno Mountain to the north and east, and Junipero Serra Boulevard and into South San Francisco to the west and south, was studied. The amount of imperviousness in the Colma Creek watershed was estimated at 63%, the highest in the County. This suggests that pollution prevention efforts here would probably be best focused on techniques to reduce pollution from parking lots, for example, and to maximize opportunities to retain open space. For more information, contact the Center for Watershed Management at http://www.cwp.org.
  Stormwater Enforcement
The Source Control Inspector is responsible for enforcement of the Stormwater Management and Discharge Control Ordinance. Enforcement will occur in the form of letters and informal violation notices exerting increasing pressure to comply. If a good faith effort to comply is not witnessed, citation will occur. It is the policy of the program that education be the primary means used to gain compliance.
