| EPA has issued three technical guides to assist environmental professionals in scoping, data management and strategic sampling activities at hazardous waste sites. EPA intends for the guides to strengthen Superfund site characterization activities to facilitate stronger site remedy decisions and improved remedy performance, among other objectives. This technical guide describes the use of "smart scoping" practices during any phase of a Superfund remedial investigation's project life cycle or in accordance with other similar federal, state or tribal regulatory authorities. Use of these practices can support the development of a robust conceptual site model (CSM), which, in turn, helps improve response action development, selection and implementation. Two additional companion technical guides should be used in conjunction with this smart scoping technical guide: Strategic Sampling Approaches and Best Practices for Data Management. |

| Reliable environmental decisions require data of known quality, which in turn requires an adequate QA/QC program to identify and control sources of error. When investigating a relatively inhomogeneous medium such as soil, the sampling component introduces much greater error than the analytical component. This document explains vital aspects of a representative sampling and analysis design, such as the concept of 'sample support,' using real-world examples and detailed discussion. |

| This document was prepared by Gabriel Sampson, a National Network for Environmental Management Studies (NNEMS) grantee under a fellowship from the U.S. Environmental Protection Agency. This paper examines the current nature of solar energy developments on closed landfills using the following focal areas: (1) solar power system considerations with respect to landfill applications, (2) landfill technical and engineering considerations, and (3) regulatory considerations. Research results indicate that numerous engineering techniques and solar technologies are available to facilitate the placement of solar energy systems on closed landfills. Results also indicate that the permitting and regulatory process is complicated by disparate but specific state and local government requirements. Though this study focuses narrowly on the technical and regulatory affairs of constructing solar farms on closed landfills, it also has applications to the placement of solar energy systems in broader settings. The views detailed in this study are designed to inform decision makers and stakeholders and to facilitate the design, construction, and operation of future solar installations on closed landfills. |

| In the OSWER Directive No. 9200.0-33, Transmittal of Final FY’00 - FY’01 Superfund Reforms Strategy, dated July 7, 2000, the Office of Solid Waste and Emergency Response outlined a commitment to optimize our Fund-lead pump and treat (P&T) systems. The Optimization Initiative is intended to encourage systematic review and modification to existing P&T systems to enhance overall remedy effectiveness and cost effectiveness, without compromising protectiveness or other objectives of the Superfund program. It provides EPA an opportunity to demonstrate our commitment to effective management of our long-term remedies. This effort recognizes that remedial approaches should not remain static, that site conditions change over time, and that better tools and strategies have evolved which allow us to continuously improve the performance of the remedy. This reform initiative does not signal any change in EPA’s decision-making framework for selecting remedies that are protective of human health and the environment. Any remedy modifications should be carried out in accordance with existing guidance and policy regarding ROD modifications and the Administrative Record. |
