Cobham Advanced Electronic Solutions

Facility Overview

Cobham Advanced Electronic Solutions is operating under a active permit of type: Industrial. Primary industry: Semiconductors and Related Devices.

The facility covers a total area of 10.25 Acres, with an active operational area of 0.85 Acres.

The site has self-reported imperviousness of 73%. 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 directly affects the Coyote 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.

  • 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.

  • Total Suspended Solids (TSS), Net Value

    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.
