Valley Forge Inc

Facility Overview

Valley Forge Inc is operating under a active permit of type: Industrial. Primary industry: Iron and Steel Forgings.

The facility covers a total area of 38530 SqFt, with an active operational area of 200 Sqft.

The site has self-reported imperviousness of 90%. 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 Big Dalton Wash. 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:

  • 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.

  • Iron, Total Recoverable

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

  • Zinc, Total Recoverable

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

  • Aluminum, Total Recoverable

    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.

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.
