The report examines the systemic failure of the U.S. coastal insurance market, specifically the National Flood Insurance Program (NFIP), which provides subsidized rates that encourage risky development and create massive taxpayer liability. It highlights how climate change—manifesting as sea level rise and stronger hurricanes—is exacerbating these risks, particularly along the East and Gulf Coasts. The author advocates for the full implementation of the Biggert-Waters Flood Insurance Reform Act of 2012 and further measures, such as incorporating sea level rise projections into FEMA flood maps and providing targeted support for low-income homeowners.

The report, authored by Dr. H.C. Clark, argues that the proposed natural gas storage in Gallery 2 is unsafe due to significant geological instabilities, including a history of massive roof collapses and the presence of major fault systems. Dr. Clark contends that the Federal Energy Regulatory Commission (FERC) and Arlington Storage Company have ignored critical historical data and failed to provide adequate geomechanical modeling or monitoring plans to address these site-specific risks.

The report details a workshop on U.S. nuclear weapons surety, distinguishing between safety (preventing accidental detonation) and security (preventing unauthorized use). While participants generally felt existing warheads were safe, they expressed greater concern over security and use control. The document examines the trade-offs of adding intrinsic surety features—such as insensitive high explosives (IHE)—during life extension programs (LEPs), noting that such changes can risk reliability and increase costs. It emphasizes that improvements outside the nuclear explosive package are faster and lower-risk. Additionally, the report addresses cybersecurity threats to command and control networks and the challenges of maintaining a 'foolproof' system involving human operators.

Combined heat and power (CHP) systems integrate heat and electric power production, achieving efficiencies of 70 percent or more compared to less than 45 percent for separate production. In the United States, there are over 4,100 systems with more than 82 GW of installed capacity, primarily in the chemical (29%), petroleum refining (18%), and pulp and paper (14%) industries. The DOE and EPA estimate an untapped potential of 130 GW, which could save U.S. businesses $10 billion annually and further reduce CO2 emissions by 150 million tons per year. Beyond efficiency, CHP provides critical resilience during extreme weather events, as demonstrated during Hurricane Sandy and Hurricanes Katrina and Rita. While biomass-fueled CHP offers a path to net carbon negative operations by avoiding methane emissions from waste, widespread deployment is hindered by regulatory and legal barriers, including interconnection standards and backup power rates.

Combined heat and power (CHP) systems in the U.S. offer significantly higher energy efficiency (70% or more) than separate heat and power production. With over 82 GW of installed capacity, CHP is widely used in industrial sectors, particularly chemicals, petroleum refining, and pulp and paper. The document highlights CHP's ability to provide resilient power during extreme weather events, such as Hurricane Sandy, and its potential to reduce CO2 emissions. While there is an untapped potential of 130 GW, deployment is hindered by regulatory and legal barriers. The text also emphasizes the climate benefits of biomass-fueled CHP, which can be net carbon negative and provide reliable baseload power.

The document explains that global sea level has risen approximately eight inches since the Industrial Revolution, driven primarily by thermal expansion and the melting of land ice due to global warming. It highlights that the U.S. East and Gulf coasts are experiencing some of the world's fastest rates of rise. Projections for 2100 range from 8 inches to 6.6 feet, with significant risks of permanent inundation, amplified storm surges, and shoreline erosion for over 100 million Americans living in coastal counties. The report argues that while adaptation is necessary, reducing heat-trapping emissions is the most effective way to limit the pace and magnitude of future sea level rise.

The Union of Concerned Scientists reports that in 2012, the NRC oversaw 14 'near-misses'—events increasing core meltdown risk by at least 10-fold—at U.S. nuclear plants. The report argues that the NRC frequently fails to enforce existing regulations, such as allowing the Palisades Nuclear Plant to operate for nearly a month despite cooling water leaks that required shutdown within six hours. It also highlights a significant perception gap between NRC senior management and staff regarding the agency's internal safety culture, where half of the workforce reported negative reactions from supervisors after raising safety concerns.

A coalition of environmental organizations argues that the EPA's proposed rules for the oil and gas industry are insufficient. They demand the direct regulation of methane, the inclusion of existing sources, the elimination of exemptions for certain wells, and the regulation of hydrogen sulfide and particulate matter. The coalition also calls for more stringent toxic air pollutant limits and a more comprehensive health risk assessment for vulnerable populations.

The document is a citizen petition submitted to the EPA requesting the promulgation of rules under the Toxic Substances Control Act (TSCA) to address the lack of public and regulatory information regarding chemicals used in oil and gas exploration and production (E&P Chemicals). The petitioners argue that current regulatory gaps—including the 'Halliburton Loophole' and inadequate Material Safety Data Sheets (MSDS)—allow the industry to conceal toxic fluids that pose unreasonable risks to human health and the environment. The petition cites evidence of groundwater contamination, air quality degradation, and animal fatalities across several U.S. states. It specifically requests that the EPA mandate toxicity testing under TSCA section 4, require detailed reporting of chemical identities and volumes under section 8(a), call in records of adverse reactions under section 8(c), and require the submission of all existing health and safety studies under section 8(d).

The document details the early application of EPA greenhouse gas (GHG) regulations for stationary sources, focusing on the role of state regulators in issuing pre-construction permits. It describes the Best Available Control Technology (BACT) analysis process, the EPA's case-by-case guidance, and the specific three-year deferral of CO2 permitting for biogenic sources. Case studies from Louisiana, Utah, and Michigan illustrate varying levels of state compliance and interpretation of EPA guidelines, while noting ongoing legal and legislative challenges to the EPA's authority.

The document asserts that environmental regulations in the United States generally cost far less than predicted by industry and the EPA, while providing substantial economic and public health benefits. It challenges claims that such regulations cause widespread job losses or force firms to relocate to 'pollution havens,' citing data that environmental spending creates jobs and that actual compliance costs are often lowered by technological innovation.

The document examines the technology and global status of offshore wind energy, noting that while Europe leads in operational capacity, the United States has significant untapped potential. It details the technical requirements for different water depths, the regulatory frameworks in countries like Denmark, and the specific siting and permitting complexities in the U.S. The text also addresses public concerns regarding tourism, wildlife, and military radar, while highlighting the economic benefits in terms of job creation and greenhouse gas reduction.

The Union of Concerned Scientists reports that the NRC has inconsistently enforced safety regulations for radioactive releases, allowing numerous accidental leaks to occur without sanction. While the NRC previously issued sanctions for monitoring and control failures, the report claims the agency has tolerated 27 accidental releases over a four-year period with impunity, effectively breaching its safety contract with the public.

The author advocates for a shift away from oil in the United States by implementing carbon or petroleum taxes to reduce demand and replacing petroleum-based fuels and materials with sustainable alternatives. The text highlights the potential for biofuels in transportation and heating, as well as the use of biomass for industrial chemicals and building products, emphasizing that such a transition must be grounded in sustainability to protect ecosystems.

A coalition of environmental organizations urges the U.S. Senate to reject expanded offshore oil and gas drilling, citing the Deepwater Horizon disaster as evidence of the inherent risks to marine ecosystems and coastal economies. The group argues that offshore reserves are insufficient to achieve energy independence and instead calls for a transition to carbon-free energy technologies and a national renewable electricity standard.

The document analyzes the challenges facing the U.S. advanced biofuels industry, including the 'valley of death' between pilot projects and commercialization, volatile petroleum prices, and regulatory uncertainties. It argues that while the federal government provides essential broad-scale support, state governments are uniquely positioned to guide the industry by leveraging local geography and resources. The report proposes ten specific policy options for states, ranging from resource inventorying and sustainable feedstock guidelines to the implementation of low carbon fuel standards and interagency cooperation, highlighting examples from states like California, Oregon, and Tennessee.

Using GIS methodology and 2006 census data, the document identifies that approximately 19 million people in the 23 coastal states of the conterminous U.S. live within 1 km of the shoreline, and 11.6 million live below a three-meter elevation. Florida, Louisiana, and New York have the highest absolute numbers of people living below 3 meters, while states like Rhode Island and Maine have high relative shares of their population within 1 km of the coast. These populations are identified as highly vulnerable to the combined effects of projected sea-level rise—estimated by the IPCC to be 18-59 cm by 2100—and increased cyclone activity.

The document details research by Nina Lam and her team at Louisiana State University using GIS and 2006 census data to map population vulnerability to sea-level rise and storms in 23 US coastal states. It finds that approximately 19 million people live within 1 km of the coast and 11.6 million live in areas below 3 meters elevation, with Florida, Louisiana, and New York having the highest numbers of vulnerable residents.

The document details the risks posed by rising temperatures and sea-level rise in the Southeast US, highlighting threats to energy and transportation infrastructure, agricultural productivity, and native ecosystems.

The document explains how nuclear power plants use water to absorb waste heat and cool equipment, detailing once-through and closed-cycle cooling systems. It highlights the significant volumes of water required, the environmental impact on aquatic life, and the critical role of the Ultimate Heat Sink (UHS) during accidents. The author argues that the primary safety hazard is not radioactive leakage, but rather the failure of water to reach the plant or leaking into the plant.
