Storm Manufacturing Group

Facility Overview

Storm Manufacturing Group is operating under a active permit of type: Industrial. Primary industry: Industrial Valves.

The facility covers a total area of 30993 SqFt, with an active operational area of 30993 Sqft.

The site has self-reported imperviousness of 98%. 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 Wilmington Drain. 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.

  • 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.

  • Nitrite Plus Nitrate (as N)

    High levels contribute to nutrient pollution, leading to algal blooms, oxygen depletion, and potential toxic conditions for aquatic life.

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.
