Get answers to all of your biggest questions here. When will the final permit be issued? IDEM issued the final Industrial Stormwater General Permit (ISGP) on [...]
Polychlorinated biphenyls, better known as PCBs, occupy a unique and often troubling place in the history of industrial chemistry. First manufactured in the late 1920s, PCBs were used for their stability, heat resistance, and insulating properties. These characteristics made them ideal for use in electrical equipment such as transformers and [...]
The Indiana Department of Environmental Management (IDEM) is rolling out its Long Term Stewardship (LTS) Program as a formalized pathway for managing sites where contamination remains in place after remediation. This program represents a significant evolution in how Indiana approaches conditional site closures, long term monitoring, and the ongoing responsibilities [...]
Underground storage tanks, often referred to as USTs, play a significant role in storing fuels and other regulated substances below the surface. They are commonly found at gas stations, industrial facilities, and commercial properties, and in some cases even at older residential sites. Because these tanks are buried, they can [...]
IDEM issued the final Industrial Stormwater General Permit (ISGP) on December 30, 2025. This permit will replace the permit-by-rule codified in 327 IAC 15-6 (“Rule 6”) which has been the stormwater permit in Indiana for the last 20+ years.

Fossil fuel-based power generation remains a cornerstone of energy production in the United States, but it comes with a complex web of environmental challenges. From fuel storage to coal combustion residuals (CCR) management, utilities face increasing regulatory scrutiny and operational risks that demand proactive strategies. Fuel Oil Storage and Spill [...]
It has been almost 10-years since U.S. EPA developed an expedited approach for cleanup under the Resource Conservation & Recovery Act (RCRA) Corrective Action Program. In 2016, the U.S. EPA issued the RCRA Facilities Investigation Remedy Selection Track: A Toolbox for Corrective Action, which is referred to as RCRA FIRST. [...]
The Resource Conservation and Recovery Act (RCRA), enacted in 1976, established the framework for the proper management of hazardous solid waste in the United States. Administered by the U.S. Environmental Protection Agency (EPA), RCRA’s primary goals are to protect human health and the environment, reduce waste, and encourage resource conservation [...]
In the world of data-driven decision-making, few tools have had as profound an impact as Monte Carlo Analysis. Known for its ability to model uncertainty and simulate complex systems, this mathematical method has roots in wartime innovation and has evolved into a cornerstone of modern analytics. The story begins in the 1940s, [...]
