Storm Water Pollution / NPDES
In order to prevent flooding, it is customary for urban areas to have numerous storm drains. The City of Monterey Park has approximately 735 catch basins or point of entries into the system. These storm drains channel water and other materials directly to the ocean.
Storm Drain Protection
The city has developed a strong program to stop the dumping and discharging of hazardous materials into storm drains. In 2018, the City achieved a Trash Total Maximum Daily Load (TMDL) compliance rate at 98.02%. In 2019, the City is striving to reach a preliminary load reduction rate at 99.01%. In July 2019, the City had installed approximately 70 catch basin trash capture devices to the City's catch basin systems to help reduce the amount of trash entering into the storm drain systems.
National Pollutant Discharge Elimination System (NPDES)
Back in 1997, to support the federal law (National Pollutant Discharge Elimination System or NPDES), the City of Monterey Park passed a Storm Water Control Ordinance. The goal of the ordinance is to protect rivers and oceans from pollutants that are dumped or washed into storm drains. View the pollution prevention program online.
Under the city's ordinance which was updated in September 2000, it is illegal for persons to release chemicals, hazardous materials, used motor oil, machinery oils, household cleaners, pesticides, grease, leaves and debris into the streets, gutters or storm drains. Please note however that practices such as car washing, sidewalk washing, and discharges from dechlorinated swimming pools and fountains are allowed.
Industrial and commercial businesses, as well as construction contractors are required to modify their operations to eliminate illegal discharge into the storm drains. Please contact us if you see the spilling or dumping of uncontrolled materials into streets, gutters, or storm drains.
Please report sewer and/or storm water back-ups to the city as soon as possible. Call Department of Public Works at 626-307-1320.
