West Miramar Waste Disposal

Facility Overview

West Miramar Waste Disposal is operating under a active permit of type: Industrial. Primary industry: Refuse Systems. Secondary industry: Scrap and Waste Materials.

The facility covers a total area of 475 Acres, with an active operational area of 74 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 Rose 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.

  • Iron, Total

    Excessive iron can harm aquatic ecosystems by forming precipitates that smother habitats. It can also affect fish gills and reduce visibility in water.

  • Lead, Total

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

  • Zinc, Total

    Excessive zinc can be toxic to aquatic organisms, particularly fish. It can accumulate in sediments and aquatic life, potentially affecting the entire food chain.

  • Arsenic, Total

    Arsenic is a toxic metalloid that can cause various health problems in wildlife and humans. It can accumulate in sediments and bioaccumulate in the food chain.

  • Mercury, Total

    Mercury is a potent neurotoxin that bioaccumulates in the food chain. It can cause severe neurological and reproductive issues in wildlife and humans.

  • 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.

  • Aluminum, Total

    Aluminum can be toxic to aquatic life, particularly in acidic conditions. It can accumulate in fish gills and affect their ability to take in oxygen.

  • 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.

  • 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.
