Enacted in 2009, ARRA bolstered the economy, in part, by funding six EPA programs. These programs included drinking water and clean water infrastructure projects through the State Revolving Funds (SRFs) and environmental initiatives through Superfund, Diesel Emissions Reduction Act (DERA), Leaking Underground Storage Tank (LUST) and Brownfields programs. The EPA contracted with Science Applications International Corporation (SAIC), and their subcontractor Toeroek Associates, Inc., to review the activities and process for funds distribution, management, and reporting for each of the six...

Taconic Energy has registered with the EPA three products within the TEA additive technology family in accordance with the regulations found in 40 Code of Federal Regulations (CFR) Part 79 of the Federal Register. Gasoline containing any of these registered materials retains their EPA baseline fuel designation. The additive family TEA-037, 037E, and 037M differ in the types and amounts of solvent systems. The active ingredient of this technology serves primarily as a friction modifier ameliorating the in-cylinder friction losses in a gasoline engine.

The workshop on Technologies and Innovative Solutions for Harvesting and Nonpotable Use of Rain and Stormwater in Urban Settings was held on April 24-25, 2013, in Cincinnati, Ohio. The purpose of this workshop was to identify: (1) innovative strategies currently being employed for the use of urban rain and stormwater; (2) water quality characteristics and standards that are protective of public health; (3) barriers and challenges to use of rain and stormwater; (4) technology gaps, needs and opportunities for innovative solutions, including those requiring further research and development; and...

The recommendations are intended to help the site team identify opportunities for improvements in these areas. In many cases, further analysis of a recommendation, beyond that provided in this report, may be needed prior to implementation of the recommendation. Note that the recommendations are based on an independent evaluation, and represent the opinions of the evaluation team. These recommendations do not constitute requirements for future action, but rather are provided for consideration by the Region and other site stakeholders. Also note that while the recommendations may provide some...

In the United States Environmental Protection Agency's (USEPA) current pesticide risk assessment process, a pair of laboratory avian reproduction tests with mallards (Anas platyrhynchos) and northern bobwhites (Colinus virginianus) is conducted to evaluate how dietary pesticide exposure affects a standard suite of reproduction endpoints (USEPA 1996). The results of these tests are used in calculating risk quotients (RQ) by comparing the reported no-observed-adverse-effect concentration (NOAEC) for the most sensitive measured endpoint(s) with estimates of the maximum dietary exposure expected...

In the United States Environmental Protection Agency's (USEPA) current pesticide risk assessment process, a pair of laboratory avian reproduction tests with mallards (Anas platyrhynchos) and northern bobwhites (Colinus virginianus) is conducted to evaluate how dietary pesticide exposure affects a standard suite of reproduction endpoints (USEPA 1996). This report was prepared for the U.S. Environmental Protection Agency by ICF International under contract. Additionally, we gratefully acknowledge the programs and individuals mentioned below for their contributions to this project.

The United States (U.S.) Environmental Protection Agency (EPA) is directed by the Safe Drinking Water Act (SDWA) to annually report on public water system (PWS) compliance in the United States. To meet this requirement, EPA's Office of Enforcement and Compliance Assurance (OECA) publishes the annual National Public Water Systems Compliance Report (Report) summarizing the incidence of significant violations, which include all health-based violations and a subset of other violations, as shown in Table A-1. The Report for 2011 documents that, while the majority of the U.S. population served by...

Every laboratory measurement involves uncertainty. When there is little or no radioactivity in a sample, one consequence of measurement uncertainty is the possibility of obtaining a measured value that is less than zero. Such a negative result occurs when random effects in the measure- ment process cause the measured value for the sample to be less than that of the blank or back- ground, which is subtracted from it. From April 1991 to December 1995, negative results were reported as "not detected" or "ND," and gamma analysis results that were less than their estimated measurement...
