PFAS or “per-and polyfluoryoalkyl substances” are a class of compounds (several thousand) that contain a chain of carbon and fluorine in their structure. PFAS have been used globally for over 60 years, and are still being used because of their many useful properties – they are chemically inert; resistant to [...]
On March 29, 2023, the U.S. EPA published the proposed PFAS Drinking Water Regulations in the Federal Register. This proposed rule for Per- and Polyfluoroalkyl Substances (PFAS) includes Maximum Contaminant Levels (MCLs) of 4.0 ng/L for two PFAS constituents (PFOA and PFOS), and an MCL using a Hazard Index of [...]
ProUCL is a statistical software package developed by the USEPA using many of the concepts found in the RCRA Unified Guidance. Originally developed to evaluate concerns at a specific Superfund site, the USEPA has, after considerable feedback from the remediation community, continued to update the software with additional features and [...]
ProUCL, a statistical software package developed by the USEPA, is a very powerful tool for evaluating environmental datasets. This webinar will discuss the applicability of ProUCL to environmental datasets, including its use in establishing background levels, determining exposure point concentrations, evaluating trends in monitoring well datasets over time, determining outliers [...]
What do non-stick coated pans, waterproof fabrics, oil-resistant food packaging, stain-resistant materials, and fire-fighting foam all have in common? They all potentially contain fluorinated compounds, and more specifically, are made with a suite of specialty chemicals called Perfluorooctanesulfonic acid (PFOS) and Perfluorooctanoic acid (PFOAs). PFOS and PFOAs both are fluorinated [...]
“Do we have RECs at our facility?” Join our webinar to learn how Environmental Health and Safety (EH&S) Managers can ensure their facility is ready for a Phase I Environmental Site Assessment.
The purpose of the Spill Prevention, Control and Countermeasure (SPCC) rule, promulgated under 40 CFR 112, is to prevent discharge of oil into navigable waters of the U.S. or adjoining shore lines. In order to better understand the SPCC rule, below are some of the fundamentals of the SPCC rule [...]
The purpose of the Spill Prevention, Control and Countermeasure (SPCC) rule is to prevent discharge of oil into navigable waters of the U.S. or adjoining shorelines as opposed to response and cleanup after a spill has occurred. This webinar will discuss the applicability to the SPCC rule, certification requirements for [...]
Abandoned sites can be damaging to the environment and can lead to expensive cleanups. Take for example the former Dayton Tire and Rubber Facility. In 1987, vandals entered the closed tire and rubber plant to recover salvageable materials. While removing copper cores from electric transformers remaining at the facility, the [...]
Do you produce, use, store, or handle regulated substances at your facility? Are you “ceasing regulated operations” or in other words discontinuing or terminating regulated operations or finalizing any transaction or proceeding through which those operations are discontinued? If so, you may be required to comply with the Ohio Environmental [...]
