美國環境保護局呼籲更嚴格的PVC管理規定

張貼日期2011-04-19

美國環境保護局在星期一提出一套更嚴格的標準. 這個標準將會要求生產用來製造硬殼平底船 (rigid inflatable boat) 及其他充氣船類的PVC的工廠減少排放有害毒素, 改善空氣品質, 保護工廠所在地居民的健康.

這個標準會降低空氣裡的毒素, 如戴奧辛及氯乙烯, 同時給工廠靈活的選擇最實際及符合成本效益的技術以減少廢氣排放. 工廠還需要在PVC生產過程的某些點上監測廢氣排放, 以確保符合標準.

PVC生產過程中產生的毒素會影響附近的社區. 全美共有17座PVC生產設施. 大多數在路易西安那州及德州. 環保局的建議將會適用於全部現有及任何新的PVC生產設施.

在聯邦公報上發佈後的60天內, 環保局會接受對該建議的評論. 環保局也將會在休士頓及路易西安那州首府巴頓魯治舉行兩場公聽會. 更多有關聽證會的資訊稍後會推出.

在另ㄧ項行動中, 環保局正在為化工業制定一套可以處理如戴奧辛和氯乙烯的空氣毒素的標準. 環保局將會在下半年發行一份提案.

PVC生產設施生產在商業及工業產品中大量使用的聚氯乙烯, 包括乳膠漆, 塗料, 膠黏劑, 透明塑膠, 硬質塑膠, 和PVC地板.

EPA calls for tougher PVC regulations

Posted on April 19, 2011

The U.S. Environmental Protection Agency on Monday proposed stronger standards that would require facilities that produce polyvinyl chloride - used to build some RIBs and other inflatable boats - to reduce emissions of harmful toxins, improving air quality and protecting people's health in communities where the facilities are located.

The standards would reduce emissions of air toxins, such as dioxin and vinyl chloride, while giving facilities the flexibility to choose the most practical and cost-effective control technology or technique to reduce their emissions. Facilities also would need to monitor emissions at certain points in the PVC production process to ensure that the standards are met.

Air toxins from the PVC production process affect nearby communities. There are 17 PVC production facilities in the United States. A majority of them are in Louisiana and Texas. The proposal would cover all existing and any new PVC production facilities.

The EPA will accept comment on the proposal for 60 days after it is published in the Federal Register. The agency also will hold two public hearings in the Houston and Baton Rouge, La., areas. More information about the hearings will be available soon.

In a separate action, the EPA is developing standards for the chemical industry that will address air toxins such as dioxins and vinyl chloride. The agency will issue a proposal for them later this year.

PVC production facilities make PVC resins that are used in a large number of commercial and industrial products, including latex paints, coatings, adhesives, clear plastics, rigid plastics and flooring.
