As a national environmental consulting and contracting firm specializing in managing hazardous substances, SCS Engineers is helping our clients now. Start by reading The Environmental Dangers of PFAS and Technologies for Removing Them, published in WasteAdvantage magazine for use in the solid waste industry and other industrial applications in support of EPA’s Action Plan.
On February 14, 2019, the U.S. Environmental Protection Agency (EPA) Acting Administrator Andrew Wheeler announced EPA’s Per- and Polyfluoroalkyl Substances (PFAS) Action Plan. The PFAS Action Plan is in response to public interest and input the EPA has received over the past year. EPA’s Action Plan identifies both short-term solutions for addressing these chemicals and long-term strategies for states, tribes, and local communities need to provide clean and safe drinking water to their residents and to address PFAS at the source. These actions include:

We will continue to see changes on the federal, state and local regulatory front that together will help us manage storm water in a smart, cost-effective manner preserving our water resources. Betsy Powers of SCS Engineers provides an update in her most recent article.
Until a new WOTUS definition is finalized, the U.S. EPA and the U.S. Department of the Army have indicated their intent to re-codify the pre-Obama regulations. The revised WOTUS rule is expected to include looser regulatory requirements, meaning fewer waters will qualify, and therefore, fewer permits will be required.
To speed up approvals of permits for highways, bridges, pipelines and other major infrastructure, an Obama-era executive order aimed at reducing exposure to flooding, sea level rise and other consequences of climate change were rolled back reducing the environmental reviews and restrictions on government-funded building projects in flood-prone areas.
Removing phosphorus from storm water runoff is a hot topic, with partners exploring alternative opportunities to reduce the introduction of phosphorus in runoff, remove it or manage it in watersheds.
More proprietary filters are being used for pretreatment before underground infiltration for redevelopment sites for total suspended solids (TSS) control and where land is limited. The performance of proprietary devices continues to be studied and improved to meet regulatory requirements. Increasing general attention is being paid to emerging contaminants that are problematic in storm water runoff. Among the emerging contaminants of concern are pharmaceutical and personal care products, pesticides, hydrocarbons, and hormones. Many of which are now included within the Endocrine Disrupting Chemicals group.

Of interest to industries concerned with wastewater ammonia treatment or landfill leachate ammonia treatment.
SCS Engineers publishes a new SCS Technical Bulletin entitled “Treatment of Ammonia in Wastewater and Leachate – Considerations and Technologies.”
Reducing the amount of ammonia in landfill leachate and other industrial wastewaters are often necessary to meet discharge standards. Proven wastewater treatment technologies can effectively reduce ammonia concentrations, but selecting the right technology requires careful consideration. This SCS Technical Bulletin provides background on ammonia in wastewater, and reviews factors to consider in selecting a treatment technology. The Bulletin includes a review of eight of the most common and effective treatment and disposal methods for wastewater with elevated ammonia or nitrogen.
