Mad RIver Lumber LLC

Facility Overview

Mad RIver Lumber LLC is operating under a active permit of type: Industrial. Primary industry: Sawmills and Planing Mills, General. Secondary industry: Logging.

The facility covers a total area of 9.4 Acres, with an active operational area of 8 Acres.

The site has self-reported imperviousness of 21%. 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 NA. 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:

  • 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.

  • 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.

  • 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.
