LA Cnty San Dist Calabasas Landfill

Facility Overview

LA Cnty San Dist Calabasas Landfill is operating under a active permit of type: Industrial. Primary industry: Refuse Systems.

The facility covers a total area of 505 Acres, with an active operational area of 100 Acres.

The site has self-reported imperviousness of 10%. In the context of the Industrial General Permit for stormwater runoff, imperviousness refers to the percentage of the facility's surface area that doesn't allow water to penetrate, such as concrete, asphalt, or rooftops. The higher the imperviousness percentage, the more potential impact on local water quality as there is a greater surface area to accumulate pollutants.

In terms of water impact, this facility indirectly affects the Las Virgenes Creek. This information is crucial for understanding the facility's potential environmental influence on local water resources.

Historical Exceedances

This facility has historically exceeded limits for the following parameters:

  • pH

    pH levels outside the normal range can harm aquatic life and affect water chemistry. Acidic water can leach toxic metals from sediments, while alkaline water can increase ammonia toxicity.

  • Oil and Grease

    Oil and grease can form films on water surfaces, reducing oxygen levels and harming aquatic life. They can also contaminate sediments and be toxic to organisms.

  • Selenium, Total

    Selenium can bioaccumulate in aquatic ecosystems, causing reproductive failure and deformities in fish and aquatic birds.

  • Ammonia, Total (as N)

    Ammonia is highly toxic to fish and other aquatic life. It can cause gill damage and affect growth and reproduction in aquatic organisms.

  • Lead, Total Recoverable

    Lead is a toxic metal that can cause neurological and reproductive problems in wildlife. It bioaccumulates in organisms and can affect entire ecosystems.

  • Selenium, Total Recoverable

    Selenium can bioaccumulate in aquatic ecosystems, causing reproductive failure and deformities in fish and aquatic birds.

  • Chemical Oxygen Demand (COD)

    High COD indicates the presence of organic pollutants. It can lead to oxygen depletion in water bodies, harming aquatic life.

  • Total Suspended Solids (TSS)

    High levels of suspended solids can reduce water clarity, harm fish gills, smother aquatic habitat and eggs, and transport pollutants through water bodies.

These limits reflect Water Quality Standards promulgated to protect human health or the environment, or standards that the State or EPA developed to indicate the Facility may be failing to implement best practices to protect storm water.
