National Pollutant Discharge Elimination System (NPDES) Commitment
It is the mission of the City of Chino Hills, in partnership with the community, to continue to develop and maintain the aesthetic beauty of the City while fostering a safe and family-orientated environment. The City is committed to the protection of its water, environmental resources, wild life, aquatic habitats, and dedicated to reducing the impact of pollutants from urban runoff, through the implementation of its Storm Water Program to ensure the health, safety and welfare of the its citizens.
In 1972, the United States (U.S.) Environmental Protection Agency (EPA) issued the NPDES program in Section 402 of the Clean Water Act (CWA) to address water pollution by regulating point source pollutants that discharge into the receiving waters of the United States. Water runoff from cities, streets, highways, industrial facilities, commercial facilities and construction sites carry pollutants that impair water quality and the recreational use of water. The U.S. EPA and the State Water Boards control runoff and the treatment of storm water through the Construction, Industrial, and Municipal regulatory permit programs.
In accordance with the CWA, Santa Ana River Basin Plan, State Water Resources Control Board (Santa Ana Region) NPDES Permit (PDF), Waste Discharge Requirements, and other state and federal laws; the City is required to perform the following activities to restore and maintain the water quality of receiving waters of the U.S.:
- Public Education/Outreach
- Reduce pollutants and manage non-storm water discharges
- Create, modify, adopt and enforce ordinances
- Storm Water Program
- Perform compliance inspections of businesses, construction sites (less than 1 acre) and other facilities
- Fats, Oil and Grease (FOG) Program
- Perform compliance monitoring and inspections of food service establishments and other commercial facilities
- Maintenance of the Municipal Storm Drain System
- Perform inspections
- Removal of trash and debris from inlets/catch basins, and channels
- Street Sweeping
- Sanitary Sewer Overflow (SSO) Program
- And more
Total Maximum Daily Loads (TMDLs)
Total Maximum Daily Load (TMDL) - is a regulatory term used in the CWA, which describes the specific amount of a pollutant such as trash, bacteria, pesticides, etc. that is allowed in a specific body of water such as lakes, rivers, streams, creeks or the ocean. When a water body is declared impaired, the State Water Resources Control Board determines the TMDL of the specific pollutant that the impaired water body can receive while still meeting water quality standards.
The City is required to comply with state and federal TMDLs to protect regional water bodies. The City has developed a monitoring and implementation plan to ensure compliance with the TMDLs concerning the following impaired water bodies within its jurisdiction:
- Chino Creek
- Prado Park Lake
- Mill Creek (Prado Area)
- Santa Ana River

Storm Water Pollution Prevention
Storm water Pollution is urban run-off from a rain event that has picked up pollutants (i.e. automobile fluids, pet waste, sediments) as it flows through the storm drain system a network of channels, gutters and pipes that collect run-off from city streets, neighborhoods, farms, construction sites and parking lots, which empties directly into local waterways.
Unlike sewage that goes to a treatment plant to remove toxins, urban run-off flows untreated through the storm drain system and directly into our local water bodies.
Anything thrown, swept or poured into the street, gutter or catch basins at the curbside openings goes into the storm drain system, which flows into our channels, creeks, Santa Ana River and eventually the Pacific Ocean.
Polluted storm water run-off is the number one source of water pollution in the United States.
Ways the Community Can Help Prevent Storm Water Pollution
- Safely dispose of all unwanted Household Hazardous Waste (HHW) (for example: used oil, paints, pesticides) at a HHW collection location. View more HHW information.
- HHW disposal is free for San Bernardino County Residents. To find the nearest HHW collection location and items accepted visit TooToxictoTrash.com.
- Never clean paint brushes or rinse paint containers in the street, gutter, catch basin or near a storm drain. Safely dispose of unwanted paint at a HHW collection location.
- Leave sprinklers on long enough to allow water to soak into the ground but not so long as to cause run-off.
- Never hose or blow grass clipping, leaves or other yard waste into the street, gutter or catch basins.
- Place grass clipping, leaves and other yard waste into the green waste recycling container. Grass clippings can have significant impacts:
- Grass clipping, leaves and other yard waste can cause catch basins to clog.
- Grass clippings contribute nutrients such as nitrogen and phosphorous, which cause unwanted and uncontrolled growth of algae and aquatic weeds in the waterways. Too much algae can be harmful, blocks sunlight and prevents other plants from growing. When algae dies and decays, it takes much needed oxygen away from aquatic life.
Storm Water Pollution Prevention - Food Service Establishments (FSE)
Since FSE discharge Fats, Oils and Grease (FOG), which can build up in sewer pipes, restrict flow and cause major problems such as sewer overflows, all FSE will be required to:
- Comply with the NPDES permit (R8-2010-0036) and FOG requirements to reduce the amount of FOG discharged to the sewer system.
- Participate in the FOG Inspection Program and meet all program requirements.
- Utilize best management practices (BMPs). BMPs include a series of activities to effectively manage and control FOG generated waste from FSE operations. BMP activities include but are not limited to:
- Good housekeeping measures ("clean kitchen practices")
- Proper Waste Disposal Methods
- Proper cleaning and maintenance of:
- Grease Interceptor
- Grease Trap
- Sand and Oil Clarifier
- FOG Spill Control Plan
Storm Water Pollution Prevention - Industrial
Industrial Facilities are regulated by the State Water Resources Control Board (SWRCB) and are required to obtain a permit from the SWRCB.
Storm Water Pollution Prevention - Construction
Construction activities (clearing, grading, stockpiling or excavation) that result in disturbance of one acre of soil or whose projects disturb less than one acre but are part of a larger common plan of development that in total disturbs one or more acres are regulated by the SWRCB and are required to obtain a permit from the SWRCB.
Storm Water Pollution Prevention - Commercial
All Commercial facilities are required to reduce run-off and prevent pollutants from entering stormdrain system (includes outdoor areas such as parking lots, trash enclosures, loading docks, and maintenance areas). Commercial facilities are required to comply with the NPDES permit (R8-2010-0036), participate in the NPDES Inspection Program and meet all program requirements.
