Standard Guidelines for Managed Aquifer Recharge, ASCE/EWRI 69-19, provides a thorough and up-to-date description of Managed Aquifer Recharge (MAR) projects. Ongoing demand for water supplies and the need for water storage have led MAR to becoming an increasingly important component for both storage and supply in regional water planning and management. Over the past several decades, much has been learned regarding how to design and implement a successful, cost-efficient MAR project and what pitfalls exist that prevent MAR success. With this standard, many water resources professionals can become aware of the benefits, techniques, standard practices, and applications of MAR. The standard includes details on planning, design, construction, operation, monitoring, and closure of MAR projects, along with background information on groundwater and MAR concepts. It also describes the economic, environmental, and legal considerations, such as water rights, laws, and regulations, as well as field investigation and testing procedures that may apply.The content of this standard has been designed to meet the needs of water resources planners and stakeholders during the initial evaluation and planning phases, along with the needs of engineers, hydrologists, and other professionals for standardization of MAR practices from conceptualization to operation and maintenance.

Prepared by the Nuclear Standards Committee and the Task Committee on Dynamic Analysis of Nuclear Structures of the Codes and Standards Activities Division of the Structural Engineering Institute of ASCESeismic Design Criteria for Structures, Systems, and Components in Nuclear Facilities provides stringent design criteria for multiple aspects associated with nuclear facilities. Because of the potential risk with nuclear hazards, nuclear facilities need to have a much lower probability than conventional facilities of sustaining structural damage caused by earthquake. The goal of this standard is to ensure that nuclear facilities can withstand the effects of earthquake ground-shaking while retaining target performance goals. Topics include evaluation of seismic demand, evaluation of structural capacity, load combinations and acceptance criteria for structures, ductile detailing requirements, equipment and distribution systems, and seismic quality provisions. This new edition, which updates and replaces the previous edition of ASCE 43, includes a new chapter on the design of seismically isolated nuclear facilities, as well as provisions for prototype and production testing of isolators. Standard ASCE/SEI 43-19 will be of use to engineers and analysts involved in the design and assessment of new or existing nuclear structures, systems, or components. It can also be used for facilities handling explosives, toxic materials, or chemicals; for facilities where safety, mission, or investment protection is an explicit design goal.

Prepared by the Committee on Oxygen Transfer Standards of the Special Standards Division of the Environmental & Water Resources Institute of ASCEMeasurement of Oxygen Transfer in Clean Water, ASCE/EWRI 2-22, provides the latest methods for measuring the rate of oxygen transfer from diffused gas and mechanical oxygenation devices to water. This standard aims to be general enough to be applied to all clean water unsteady-state tests and specific enough to incorporate all essential procedures.This standard is an update of the 2006 version. Revisions to the mandatory requirements include use of the nonlinear least squares estimates for parameter fitting, the need to correct and report results to a common TSS level, and acceptance of a nitrogen gas method for deoxygenation. A new commentary provides a detailed description of a supersaturated oxygen desorption method. This method may be incorporated into a future revision of the standard as an acceptable method, pending a comparison of results with existing deoxygenation methods.ASCE 2-22 is meant to be used by engineers in the preparation of specifications for compliance testing by manufacturers developing performance information and is applicable to laboratory scale oxygenation devices with water volumes of a few gallons, as well as to full-scale systems with water volumes typical of those found in the activated sludge wastewater treatment process.

Prepared by the Dry Dock Standards Committee of the Ports and Harbors Committee of the Coasts, Oceans, Ports, and Rivers Institute (COPRI) of ASCEDry Dock Standard, ASCE/COPRI Standard 77-22, is intended to address a deficiency in commercial shipyards, specifically safety certification of dry docking facilities. The US Navy has a standard for certifying facilities that drydock its ships. In addition, the US Coast Guard has a procedure for certifying facilities that drydock its ships. However, there has been no commercial standard for certifying dry docks. Many dry dock owners and operators obtain "commercial certifications" from third-party engineers, yet these certifications are not performed to a standard and are typically focused on the structural capacity. Dry dock accidents have occurred many times over the last two decades, attributable to inadequate maintenance and inspections. The intent of this standard is to minimize the risk to personnel and the ships being drydocked. In addition, emphasis on maintenance and inspection provides the insight for facility owners and operators to enable repairs before the catastrophic loss of their capital assets.This standard is intended for use by dry dock owners, Dockmasters, dry dock maintenance engineers, engineers engaged in dry dock inspection and certification, ship owners, and port engineers.

Prepared by the Seismic Evaluation and Retrofit of Existing Buildings Committee of the Codes and Standards Activities Division of the Structural Engineering Institute of ASCESeismic Evaluation and Retrofit of Existing Buildings, Standard ASCE/SEI 41-23, describes deficiency-based and systematic procedures that use performance-based principles to evaluate and retrofit existing buildings to withstand the effects of earthquakes. The standard presents a three-tiered process for seismic evaluation according to a range of building performance levels by connecting targeted structural performance and the performance of nonstructural components with seismic hazard levels. The deficiency-based procedures allow evaluation and retrofit efforts to focus on specific potential deficiencies deemed to be of concern for a specified set of building types and heights. The systematic procedure, applicable to any building, sets forth a methodology to evaluate the entire building in a rigorous manner. This standard establishes analysis procedures and acceptance criteria and specifies requirements for foundations and geologic site hazards; components made of steel, concrete, masonry, wood, and cold-formed steel; architectural, mechanical, and electrical components and systems; and seismic isolation and energy dissipation systems. Checklists are provided for a variety of building types and seismicity levels in support of the Tier 1 screening process. This new edition, which updates and replaces previous versions of ASCE 41, introduces provisions to align with the multipoint response spectra in the new USGS seismic hazard model. The standard now points to AISC 342 and ACI 369 for provisions related to structural steel and reinforced concrete existing buildings, respectively, both of which significantly revised the provisions found in the 2017 edition of the standard. There are a number of other changes, including significant revisions to the nonlinear analysis provisions, how to develop structural component modeling parameters and acceptance criteria, and provisions for unreinforced and reinforced masonry.ASCE 41-23 is a primary reference for structural engineers addressing the seismic resilience of existing buildings and for building code officials reviewing such work. It also will be of interest to architects, construction managers, academic researchers, and building owners.
