Facility Overview

Summit Machine LLC is operating under a active permit of type: Industrial. Primary industry: Industrial and Commercial Machinery and Equipment, NEC. Secondary industry: Aircraft Engines and Engine Parts. Tertiary industry: Aircraft Parts and Auxiliary Equipment, NEC.

The facility covers a total area of 6.35 Acres, with an active operational area of 6.35 Acres.

The site has self-reported imperviousness of 95%. 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 Cucamonga 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.

  • 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.
