|     strategies for (1) adapting to a changing     |         |       |
|     climate, (2) mitigating greenhouse gases,     |         |       |

|     strategies that also result in reductions in  |         |       |
|     greenhouse gas emissions. The tool is a       |         |       |
|     first-of-a-kind, nine-region MARKAL model of  |         |       |

|     some of the needs identified by Region 1. It  |         |       |
|     can, for example, be used by the New England  |         |       |
|     Governors/Canadian Premiers to evaluate       |         |       |
|     alternative strategies for attaining the      |         |       |

| -   **Bauxite Capping Studies:** Bauxite has been |         |       |
|     found to be capable of sequestering a broad   |         |       |
|     variety of heavy metals, including Hg, As,    |         |       |
|     Cr, Cd, Pb, Zn, and Ni. Due to its unique     |         |       |
|     surface properties, bauxite is able to        |         |       |
|     sequester both cationic and oxy-anionic forms |         |       |
|     of the metals through a combination of        |         |       |
|     adsorption, absorption, ion exchange, and     |         |       |
|     precipitation. Bauxite can be installed as a  |         |       |
|     much thinner cap over the contaminated        |         |       |
|     sediments, a critical parameter for remedy    |         |       |

|     of quantifying contaminant transport          |         |       |
|     mechanisms to facilitate the prediction of    |         |       |

|     both amendments and construction techniques   |         |       |
|     (e.g., mats), will continue to be             |         |       |

|     through a sand cap and resuspension during    |         |       |
|     cap placement to identify potential field     |         |       |
|     methods for minimizing sediment resuspension  |         |       |
|     during cap placement. The research indicated  |         |       |
|     that resuspension can be minimized by using   |         |       |
|     improved release techniques that result in    |         |       |
|     fewer disturbances of the contaminated        |         |       |
|     sediment.                                     |         |       |

|     completed in September 2007, indicate that an |         |       |
|     \"active\" cap (AquaBlok technology) can be   |         |       |
|     adequately placed over a contaminated         |         |       |

|     limited impact on the re-establishment of     |         |       |
|     flora and fauna. This information is useful   |         |       |
|     to EPA's Superfund program since effectively  |         |       |
|     capping a contaminated site is less expensive |         |       |
|     than dredging and off-site treatment, with    |         |       |
|     less environmental disturbances. The          |         |       |
|     demonstration also indicated that             |         |       |

|     quantified and compared the PM and gaseous    |         |       |
|     exhaust pollutants emitted from selected      |         |       |
|     diesel school buses which were shut down and  |         |       |
|     ultimately restarted and those which idled    |         |       |
|     continuously. Fine particulate matter (PM),   |         |       |
|     particulate polycyclic aromatic hydrocarbons  |         |       |
|     (PAHs), carbon monoxide (CO), total           |         |       |
|     hydrocarbons (THC), nitrogen oxides (NOx),    |         |       |

|     enhance a database known as SPECIATE which is |         |       |
|     a repository for emission profiles. The       |         |       |
|     profiles are organized by source category and |         |       |
|     include the range of diesel sources. The      |         |       |
|     profiles contain volatile organic compounds   |         |       |
|     (VOC) and Particulate Matter (PM) species.    |         |       |
|     The VOC species are grouped into reactivity   |         |       |
|     classes to support ozone air quality          |         |       |
|     modeling. The PM species contain information  |         |       |
|     on size and composition and are used to       |         |       |
|     support PM and visibility air quality         |         |       |
|     modeling. The database has also supported air |         |       |
|     toxic assessments and is integral to source   |         |       |
|     receptor modeling applications.               |         |       |

|     (who may be more susceptible to the disease   |         |       |
|     outcomes) consume more fish and thereby       |         |       |

|     The method was tested (Demolition #1) at Ft.  |         |       |
|     Chaffee, AR in April, 2006, by demolishing    |         |       |

|     buildings, one using the common NESHAP method |         |       |
|     and the other using the AACM. The AACM        |         |       |
|     performed well, being as environmentally      |         |       |
|     protective, but being faster and cheaper. A   |         |       |
|     second demolition at Ft. Chaffee, using a     |         |       |
|     two-story structure (Demolition #2), was      |         |       |

| -   NRMRL is working with the NERL and NASA |     | E |      |   |     |
|     to construct and evaluate a new         |     | R |      |   |     |

|     bi-directional NH3 exchange with        |     |   |      |   |     |
|     vegetation. The MLBC model will         |     | N |      |   |     |
|     eventually be incorporated into the     |     | E |      |   |     |

|     regional modeling tool for regulatory   |     | / |      |   |     |

|     emissions from fossil fuel and          |     |   |      |   |     |
|     agricultural sources. Recent studies    |     | N |      |   |     |
|     suggest that isotope chemistry is a     |     | R |      |   |     |
|     useful method for tracking subsurface   |     | M |      |   |     |
|     nitrogen movement from agricultural     |     | R |      |   |     |

| -   As a consequence of the, then, prevalence of |         |        |
|     the Johnson and Ettinger model in vapor      |         |        |
|     intrusion assessment, we undertook a more    |         |        |
|     detailed evaluation of uncertainties         |         |        |
|     associated with its results. We determined,  |         |        |
|     when all parameters were considered          |         |        |
|     simultaneously, that the uncertainties in    |         |        |
|     the model results were greater than          |         |        |
|     previously appreciated. From these analyses  |         |        |
|     we developed a set of upper and lower-bound  |         |        |
|     parameters for use in bounding vapor         |         |        |
|     intrusion assessments. The purpose of this   |         |        |
|     work was to establish sets of parameters     |         |        |
|     that could be assured to generate best or    |         |        |
|     worst case exposure assessments, given       |         |        |
|     uncertainty in the parameter values.         |         |        |

| -   The issue of mercury methylation is one that | cheraga |        |
|     was identified as being important in the     |         |        |
|     2003 Multi-Year Plan for the Mercury         | NE      |        |
|     Research Program. Unfortunately, given the   | RL/Matt |        |
|     very limited budget available for mercury    | Landis  |        |
|     research in ORD, it will be not be possible  |         |        |

| -   The Mercury Research Program has had to      |         |        |
|     narrow the focus of the program to the       |         |        |
|     highest-priority research activity;          |         |        |
|     specifically, the evaluation of the          |         |        |

|     implications for the effectiveness of the    |         |        |
|     CAMR -- is the key problem that the Mercury  |         |        |
