Truckee River2Common pollutants include: greasy mop water, food waste leaking from dumpsters, automotive fluids (such as antifreeze and motor oil), concrete and painting related wastewater, commercial vehicle washing wastewater, pressure washing wastewater, and sediment (dirt and sand).

Examples of situation where stormwater runoff could be polluted through exposure to pollutants include:

  • Improper or incomplete clean-up of a release or spill of hazardous or non-hazardous materials or wastes in an outdoor, uncovered area
  • Poor housekeeping in outdoor storage areas
  • Inadequate secondary containment and/or coverage of hazardous or non-hazardous materials of wastes
  • Leaky dumpsters, or dumpster lids left open
  • Liquids of powdery materials tracked outdoors by forklifts or other vehicles from indoor processing areas
  • Leaky vehicles, equipment, compressors, etc. 

Auto Industry

Discharges of wastewater from commercial auto washing, and detailing to the storm drain system is very common. However, these discharges are prohibited by Truckee’s stormwater ordinance, as well as state and federal law. This prohibition applies to people and companies washing cars as parts of any commercial enterprise including.

Restaurants and Food Handling Facilities

Food facilities – restaurants, cafeterias, coffee shops, bakeries, and grocery stores – must not allow the discharge of wastewater, grease, food-related wastes, and other materials from going into the storm drains. This is a violation of the Truckee’s stormwater quality ordinance and California Health and Safety Code.

Painting Without Polluting

Improper disposal of paint is very harmful to the environment. Waste materials from painting include excess paint, used thinner, cleanup water and wastes from preparation works. Paints contain chemicals that are harmful to aquatic life and drinking water supplies.

Several steps can be taken to pollute less during your painting projects:

  • Avoid buying too much paint.
  • Brush out as much paint as possible before cleaning brushes.
  • Recycle excess paint. For more information visit Keep Truckee Green.
    • PaintCare partner in the Town of Truckee is Mountain Hardware.
  • Carefully store leftover paint.
  • Discard dry paint cans. Once cans are COMPLETELY dried, place in curbside trash can.

Mobile Cleaning Industry

Most mobile cleaning businesses conduct their work outside, which often results in discharge of wastewater to the storm drain. Many pollutants enter storm drains from these practices because of the objects or surfaces being cleaned and/or from the cleaning compounds being used. 

Driveway sealing is often most effective if the existing surface is thoroughly cleaned. However, with the emergency drought regulations and existing stormwater regulations washing down a surface prior to resurfacing is now much more complex. The emergency drought regulations prohibit the use of potable water for washing driveways and sidewalks. Non-potable water which can be used is considered a non-stormwater discharge and is not permitted to be discharged down storm drains. So what is the solution?

It is recommended that sweeping be used to clean the surface. However, if non-potable water is used then all water must me captured and collected (vacuumed). Non-potable water may not be allowed to enter the storm drain system (MS4). Additionally, sediment and debris from washing must never enter the storm drain system. Use appropriate BMPs to protect storm drains and ditches from receiving sediment and debris from cleaning operations. Visit the Town of Truckee's  Mobile Cleaning Brochure for more information.
