  • Sector N: Scrap and Waste Recycling
    Industrial Stormwater Fact Sheet Series Sector N: Scrap Recycling and Waste Recycling Facilities U.S. EPA Office of Water EPA-833-F-06-029 February 2021 What is the NPDES stormwater program for industrial activity? Activities, such as material handling and storage, equipment maintenance and cleaning, industrial processing or other operations that occur at industrial facilities are often exposed to stormwater. The runoff from these areas may discharge pollutants directly into nearby waterbodies or indirectly via storm sewer systems, thereby degrading water quality. In 1990, the U.S. Environmental Protection Agency (EPA) developed permitting regulations under the National Pollutant Discharge Elimination System (NPDES) to control stormwater discharges associated with eleven categories of industrial activity. As a result, NPDES permitting authorities, which may be either EPA or a state environmental agency, issue stormwater permits to control runoff from these industrial facilities. What types of industrial facilities are required to obtain permit coverage? This fact sheet specifically discusses stormwater discharges various industries including scrap recycling and waste recycling facilities as defined by Standard Industrial Classification (SIC) Major Group Code 50 (5093). Facilities and products in this group fall under the following categories, all of which require coverage under an industrial stormwater permit: ◆ Scrap and waste recycling facilities (non-source separated, non-liquid recyclable materials) engaged in processing, reclaiming, and wholesale distribution of scrap and waste materials such as ferrous and nonferrous metals, paper, plastic, cardboard, glass, and animal hides. ◆ Waste recycling facilities (liquid recyclable materials) engaged in reclaiming and recycling liquid wastes such as used oil, antifreeze, mineral spirits, and industrial solvents.

  • Cabin Air Quality Brief
    Briefing paper Cabin air quality – Risk of communicable diseases transmission The overall risk of contracting a disease from an ill person onboard an airplane is similar to that in other confined areas with high occupant density, such as a bus, a subway, or movie theatre for a similar time of exposure. anywhere where a person is in close contact with others. That said, the risk on airplanes is probably lower than in many confined spaces because modern airplanes have cabin air filtration systems equipped with HEPA filters. HEPA or high efficiency particulate air filters have similar performance to those used to keep the air clean in hospital operating rooms and industrial clean rooms. These filters are very effective at trapping microscopic particles as small as bacteria and viruses. HEPA filters are effective at capturing greater than 99 percent of the airborne microbes in the filtered air. Filtered, recirculated air provides higher cabin humidity levels and lower particulate levels than 100% outside air systems. The cabin air system is designed to operate most efficiently by delivering approximately 50 percent outside air and 50 percent filtered, recirculated air. This normally provides between 15 to 20 cubic feet of total air supply per minute per person in economy class. The total air supply is essentially sterile and particle-free. Cabin air circulation is continuous. Air is always flowing into and out of the cabin. Total airflow to the cabin is supplied at a bulk flow rate equivalent to 20 to 30 air changes per hour. This provides temperature control and minimizes temperature gradients within the cabin.

  • HEPA Vs Electrostatic Getting Terms and Technologies Right Efficiency
    HEPA vs Electrostatic Many articles try to compare HEPA and Electrostatic filtration. It seems that every article chooses one or the other rather than comparing the two. Sometimes HEPA is the clear choice for a filtration system. Other times an Electrostatic precipitator is a better fit for the air quality issues in a space. In this article we will try to present a clear comparison without bias. The only goal is to help you become a well-informed consumer. Getting terms and technologies right Before we get started let’s clarify our terms and technologies. Not all manufacturers use the right terms when describing the tecnologies. To more clearly understand our comparison, we will take a brief look at both technologies in the HEPA vs Electrostatic comparison. HEPA type and true HEPA Many air purifier manufacturers misuse the term HEPA. They refer to air filters that remove less than 99.97% of dust particles as a HEPA filter. While many of these HEPA type filters may do an adequate job, they should not be referred to as HEPA. When comparing a HEPA Air filter to an electrostatic air purifier, be sure the filter contained is true HEPA. Be certain that it is rated for 99.97% removal of dust particles 0.3 to 10 microns. Electrostatic precipitator and electrostatic media There it is a common misunderstanding that all Electrostatic filtration is the same. There are two basic types of Electrostatic filtration. One is electrostatically charged filter media, and the other is an Electrostatic precipitator. Electrostatic media is created by giving a normal filter an electrostatic charge.
