Scientists are reporting new evidence that the Deepwater Horizon oil spill has affected marine life in the Gulf of Mexico, this time species that live in dark ocean depths--deepwater corals.
The research used a range of underwater vehicles, including the submarine Alvin, to investigate the corals. The findings are published this week in the journal Proceedings of the National Academy of Sciences (PNAS).
The scientists used a method known as ...

Air Toxic Emissions Standards for PVC Finalized

News release from EPA:


FOR IMMEDIATE RELEASE
February 14, 2012
  
EPA Finalizes Air Toxic Emissions Standards for Polyvinyl Chloride (PVC) Production Facilities
  
Standards will cut harmful emissions that impact local communities
   
WASHINGTON – The U.S. Environmental Protection Agency (EPA) today issued strong final standards requiring facilities that produce polyvinyl chloride and copolymers (PVC) to reduce harmful air emissions, which will improve air quality and protect people’s health in communities where facilities are located. Exposure to toxic air pollutants, like those emitted from PVC facilities, can cause respiratory problems and other serious health issues, and can increase the risk of developing cancer. In particular, children are known to be more sensitive to the cancer risks posed by inhaling vinyl chloride, one of the known carcinogens emitted from PVC facilities.

The final standards are based on currently available technologies and will reduce emissions of air toxics, such as dioxin and vinyl chloride. Facilities will have the flexibility to choose the most practical and cost-effective control technology or technique to reduce the emissions. Facilities will be required to monitor emissions at certain points in the PVC production process to ensure that the standards are met.

Currently, there are 17 PVC production facilities throughout the United States, with a majority of these facilities located in Louisiana and Texas. All existing and any new PVC production facilities are covered by the final rule.

PVC production facilities manufacture PVC resins that are used to make a large number of commercial and industrial products at other manufacturing facilities. These products include latex paints, coatings, adhesives, clear plastics, rigid plastics, and flooring.

EPA had a 74-day public comment period and held two public hearings on the proposal before issuing the final rule.
