Since the application of New Source Review (NSR) regulation in themid-1970’s, process vents of any new or modified source with emission increases must meet the Best Available Control Technology (BACT) standards, which, for VOC sources, usually means venting to a combustion device meeting a specified destruction or reduction efficiency.
自20世紀(jì)70年代中期開始執(zhí)行新排放源評(píng)估（NSR）規(guī)定以來，任何增加排放的新排放源或改性排放源，其工藝廢氣必須符合最佳可行控制技術(shù)（BACT）標(biāo)準(zhǔn)。這對(duì)于揮發(fā)性有機(jī)物排放源，通常意味著燃燒設(shè)備的通風(fēng)口必須符合指定的破壞或去除效率標(biāo)準(zhǔn)。
In non-attainment areas such as the Los Angeles region, the residual VOC emissions also must be offset by an equivalent or greater amount of emissions reduction credits (ERCs) such that there are no net emission increases for the region.
在洛杉磯地區(qū)等未達(dá)標(biāo)區(qū)域，殘余揮發(fā)性有機(jī)物排放量必須以相等或更高的減排額度（ERC）抵消，避免該地區(qū)出現(xiàn)凈排放量增長。
The urgent needs for further VOC control since the 1990’s have pushed all stakeholders to more closely examine and identify all additional sources and/or more effective control measures. Among them, the Leak Detection and Repair (LDAR) programs for millions of fugitive components, further control of storage tank evaporative emissions, control of emissions from waste water systems, and flare gas monitoring/recovery were some of the more recent key developments.
自20世紀(jì)90年代以來，進(jìn)一步加強(qiáng)揮發(fā)性有機(jī)物排放控制變得日益緊迫，促使所有利益相關(guān)者更重視研究和發(fā)現(xiàn)所有其他排放源和/或更有效的控制措施。其中，最近出臺(tái)的控制措施包括針對(duì)數(shù)百萬個(gè)逸散排放組件的泄漏檢測(cè)與修復(fù)（LDAR）計(jì)劃、加強(qiáng)控制儲(chǔ)油罐蒸發(fā)性排放、控制廢水系統(tǒng)排放以及火炬氣監(jiān)控/回收等。
