The U.S. Environmental Protection Agency (EPA) developed a year 2007 air quality modeling platform in support of the Tier 3 Motor Vehicle Emission and Fuel Standards. The air quality modeling platform consists of all of the emissions inventories, ancillary files needed for emissions modeling, and the meteorological, initial condition, and boundary condition files needed to run the air quality model. This platform uses all Criteria Air Pollutants (CAPs) and a select set of Hazardous Air Pollutants (HAPs). This document focuses on the emissions modeling components of the 2007 platform, including the emission inventories and the ancillary data and the approaches used to transform emission inventories for use in air quality modeling.

Sandia National Laboratories/New Mexico's (SNL/NM) Environmental Management System is the integrated approach for members of the workforce to identify and manage environmental risks. Each Fiscal Year (FY) SNL/NM performs an analysis to identify environmental aspects, and the environmental programs associated with them are charged with the task of routinely monitoring and measuring the objectives and targets that are established to mitigate potential impacts of SNL/NMs operations on the environment. An annual summary of the results achieved towards meeting established objectives and targets provides a connection to, and rational for, annually revised environmental aspects. The purpose of this document is to summarize the results achieved and documented in FY2012.

The establishment of many facilities to power the growing business operational requirements has led to a rapid increase in power consumption as well as carbon emissions.

本研究通过对厌氧折流板反应器（ABR）改进，使其成为厌氧与好氧组合一体化工艺，实现耦合运行。对连续流条件下其好氧颗粒污泥形成机制进行了研究。将ABR末端隔室分别改为曝气池与沉淀池，并分别在厌氧区和好氧区接种厌氧颗粒污泥和普通活性污泥，保持好氧区C/N为2，COD容积负荷逐渐由1.5kg﹒(m3﹒d)-1提高至2.0kg﹒(m3﹒d)-1，沉淀池HRT逐步由2.0h缩短至0.75h。研究表明，经110d的运行，在好氧区中成功培养结构致密、沉降性能良好（平均沉降速率为20.8m﹒h-1）的淡黄色颗粒污泥。在好氧区沉淀时间为0.75h、COD容积负荷为2.0kg﹒(m3﹒d)-1的条件下，系统稳定运行时具有较好的脱氮除磷效果，COD、NH4+ -N、TP和TN的去除率分别为90%、80%、65%和45%。研究表明，因沉淀时间缩短而不断提高的选择压、维持较高的有机负荷是好氧颗粒污泥形成的主要驱动力。

主要研究了不同浓度的天然溶解性有机物（DOM）对单片膜被动采样技术的影响。结果表明，DOM的存在会影响膜吸附有机污染物的能力：当lgKow为3~5时，DOM对膜吸附有机物的影响较小；当lgKow>5.5时，DOM会显著增强膜的吸附能力，同时，通过低密度聚乙烯膜（LDPE）被动采样技术对太子河流域3个表层沉积物的孔隙水进行多环芳烃类（PAHs）和邻苯二甲酸酯类（PAEs）监测。结果表明，所选取的几种目标污染物在各监测点均有不同程度的检出，最后，利用商值法对太子河流域的PAHs和PAEs进行生态风险评价。结果表明，荧蒽超过水生生态基准值，其生态风险较大。

以凹凸棒土（凹土，ATP）为原料，采用浸渍法制备Fe3+负载凹土（Fe/ATP），表征了其结构与形貌，研究了凹土和Fe/ATP对土壤中镉（Cd）的吸附效果，以浸出浓度作为稳定化评价指标，通过吸附前后凹土和Fe/ATP形貌等特征的变化探讨了稳定化修复Cd机制。结果表明，加入质量比20%的凹土和Fe/ATP，Cd的浸出浓度分别降低了45%和91%，说明Fe/ATP对土壤中Cd有显著的稳定化作用。形貌表征分析表明，凹土主要通过结构中的水、-OH基团和晶格缺陷来稳定Cd，而Fe/ATP对土壤中Cd稳定化作用可能主要来自-OH基团以及Fe-O中桥氧的贡献。凹土与氧化铁均为土壤中天然矿物，廉价易得且环境友好，制备方法简单易实现，该复合材料用于Cd污染土壤的稳定化修复具有较好的应用前景。

The U.S. Department of Energy, National Nuclear Security Administration Nevada Field Office (NNSA/NFO) operates the Nevada National Security Site (NNSS) and North Las Vegas Facility (NLVF). From 1951 through 1992, the NNSS was the continental testing location for U.S. nuclear weapons. The release of radionuclides from NNSS activities has been monitored since the initiation of atmospheric testing. Limitation to underground detonations after 1962 greatly reduced radiation exposure to the public surrounding the NNSS. After nuclear testing ended in 1992, NNSS radiation monitoring focused on detecting airborne radionuclides from historically contaminated soils. These radionuclides are derived from re-suspension of soil (primarily by wind) and emission of tritium-contaminated soil moisture through evapotranspiration. Low amounts of legacy-related tritium are also emitted to air at the NLVF, an NNSS support complex in North Las Vegas. To protect the public from harmful levels of man-made radiation, the Clean Air Act, National Emission Standards for Hazardous Air Pollutants (NESHAP) (Title 40 Code of Federal Regulations (CFR) Part 61 Subpart H) (CFR 2010a) limits the release of radioactivity from a U.S. Department of Energy (DOE) facility to that which would cause 10 millirem per year (mrem/yr) effective dose equivalent to any member of the public. This limit does not include radiation unrelated to NNSS activities. Unrelated doses could come from naturally occurring radioactive elements, from sources such as medically or commercially used radionuclides, or from sources outside of the United States, such as the damaged Fukushima nuclear power plant in Japan in 2011.

The U.S. Geological Survey Branch of Quality Systems operates the Precipitation Chemistry Quality Assurance project (PCQA) to provide independent, external quality-assurance for the National Atmospheric Deposition Program (NADP). NADP is composed of five monitoring networks that measure the chemical composition of precipitation and ambient air. PCQA and the NADP Program Office completed five short-term studies to investigate the effects of equipment performance with respect to the National Trends Network (NTN) and Mercury Deposition Network (MDN) data quality: sample evaporation from NTN collectors; sample volume and mercury loss from MDN collectors; mercury adsorption to MDN collector glassware, grid-type precipitation sensors for precipitation collectors, and the effects of an NTN collector wind shield on sample catch efficiency.
