Facility Overview
Southwest Processors Inc is operating under a active permit of type: Industrial. Primary industry: Sewerage Systems. Secondary industry: Refuse Systems. Tertiary industry: Animal and Marine Fats and Oils.
The site has self-reported imperviousness of 7%. 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 Los Angeles River. This information is crucial for understanding the facility's potential environmental influence on local water resources.
Additional Details
Historical Exceedances
This facility has historically exceeded limits for the following parameters:
Silver, Total
Silver is highly toxic to aquatic organisms, particularly in its ionic form. It can disrupt fish gill function and affect lower trophic level organisms.
Mercury, Total
Mercury is a potent neurotoxin that bioaccumulates in the food chain. It can cause severe neurological and reproductive issues in wildlife and humans.
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.
Selenium, Total
Selenium can bioaccumulate in aquatic ecosystems, causing reproductive failure and deformities in fish and aquatic birds.
Magnesium, Total
While essential in small amounts, excessive magnesium can contribute to water hardness, affecting aquatic life and ecosystem balance.
Cyanide, Total (as CN)
Cyanide is extremely toxic to aquatic life, even in low concentrations. It can cause immediate mortality in fish and other organisms.
Nitrite Plus Nitrate (as N)
High levels contribute to nutrient pollution, leading to algal blooms, oxygen depletion, and potential toxic conditions for aquatic life.
Chemical Oxygen Demand (COD)
High COD indicates the presence of organic pollutants. It can lead to oxygen depletion in water bodies, harming aquatic life.
Biochemical Oxygen Demand (BOD) (5-day @ 20 Deg. C)
Elevated BOD levels indicate high organic pollution, which can deplete oxygen in water, leading to fish kills and ecosystem imbalance.
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.
