1 The term ‘‘WTC-related’’ was not included in the proposed definition of acute traumatic injury in the notice of proposed rulemaking, 80 FR 54746 (Sept. 11, 2015), but has been added in the final rule to clarify specific usage in the WTC Health Program and better parallel ‘‘WTC-related musculoskeletal disorder’’ on the List. The Administrator finds that revising the term results in no substant...

Stormwater runoff can transport a variety of pollutants including heavy metals, excess nutrients, sediments, trash, etc. Several studies dating back to the 1970s have shown that a number of human pathogens are often present in stormwater and can lead to serious health risks. The resulting health and economic impacts can be significant since the presence of elevated concentrations of microorgani...

introduction water quality trading (wqt) is an economically incentive-based strategy that focuses on finding the optimal discharge permit market for surface water quality management. the amounts of traded discharge permits determine the interactions of emission sources in the market. pollutantsthat are able to provide extra permits can satisfy the demands of other participants for credits. find...

Water quality trading between point and nonpoint sources is of great interest as an alternative to strict command and control regulations on point sources for achieving water quality goals. The expectation is that trading will reduce the costs of water quality protection, and may speed compliance. The United States Environmental Protection Agency has issued guidance to the States on developing ...

Researchers at the Information Center for the Environment (ICE) are using ArcGIS to inventory and monitor environmental risks to California’s north, coastal watersheds. In collaboration with state agencies, ICE has created a comprehensive GIS for selected watersheds in which water quality improvement and endangered species recovery is paramount. ICE has leveraged hyperspectral imagery, extensiv...

Dissolved oxygen (DO) levels in the Little River, a tributary within the Suwannee River basin of southern Georgia, regularly drop below 1 mg L. A budget of coarse particulate organic matter (CPOM) dynamics and the oxygen demand generated by associated microbial respiration is being developed for thirdand fifth-order reaches of the Little River. Our CPOM budget will include riparian inputs, stan...

of agricultural P to water quality. In Florida, FHANTM 2.0 (Field Hydrologic and Nutrient Transport Model, Pollution of surface waters by P from agricultural areas is a water version 2.0; Fraisse and Campbell, 1997) was developed quality issue in Delaware. The FHANTM 2.0 computer model can help identify areas with a high potential for P loss, but the model’s to simulate water and P movement fro...

Given the myriad of policy instruments aimed at enhancing water quantity conservation available to municipalities, what drives them opt for a market-based instrument (MBI)? MBIs can be effective and efficient enhance conservation, but there is little known about why municipalities utilize them. This study hypothesizes that three contextual elements influence municipality's use an MBI: natural, ...

Many of the issues of importance to forest management and policy have important social components. Yet, in the South, social research on forests has lagged behind economic and biophysical research. In this paper we identify some important new opportunities for social research on forests in the South, focusing on non industrial private forests because they represent the majority of the South's t...
