EPA Releases First of Twelve Datasets on PFAS and Lithium in Drinking Water

September 14, 2023

SCS Engineers Environmental Consulting and Contracting
Managing and Treating PFAS and Lithium

 

On August 17, 2023, the United States Environmental Protection Agency (EPA) released the first of twelve datasets (representing approximately 7% of the total data that it plans to collect) on 29 polyfluoroalkyl substances (PFAS) and lithium (an alkali metal) in our nation’s drinking water. This sampling will continue through 2026, and is the latest action delivering on the EPA PFAS Strategic Roadmap, which dictates that PFAS (an emerging contaminant pending regulations under CERCLA) requires a multi-agency approach and specific actionable steps to assess risks to human and environmental health better, hold polluters accountable, and identify the extent of the problem.

Monitoring PFAS and lithium is currently under the fifth Unregulated Contaminant Monitoring Rule (UCMR 5). The Safe Drinking Water Act (SDWA) requires that the EPA issue a list of unregulated but potentially harmful contaminants every five years and devise a protocol for monitoring those contaminants in public water systems (PWSs).

The current UCMR 5 regulatory framework allows for collecting PFAS and lithium data throughout the United States. It aims to create science-based decision-making regarding how to address these chemicals best. Results, which will get quarterly updates, can be reviewed by the public on the EPA’s National Contaminant Occurrence Database.

While there is not currently a final drinking water standard in place for PFAS, EPA has already issued health advisories for four PFAS compounds, and two of them – perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) – have also been proposed for entry as hazardous substances under CERCLA, as of March 2023. The timeline for the final rule on PFAS CERCLA designation is now February 2024. Landfills and other passive receivers are seeking relief from CERCLA contribution litigation prior to designating PFAS as hazardous substances, as they have no control over the use and disposal of hundreds of thousands of products containing PFOA and PFOS.

This first set of data does appear to raise some red flags, though it is not uniformly indicative of widespread contamination. In Missouri, for example, 1,923 distinct water samples were obtained from 22 different PWSs (from a mix of wells and treatment plants) in communities throughout the state. Of these samples, 23 are scattered between 11 facilities containing lithium at concentrations in excess of the laboratory Method Reporting Limit (MRL) of 9 micrograms per liter (µg/L), some by many orders of magnitude. Only two PFAS compounds (PFOS and PFHxS) are above their MRLs (0.004 µg/L and 0.003 µg/L, respectively), both from the North Rodeo Well of the Camdenton PWS.

This data will ultimately be immensely useful for public sector officials trying to make policy decisions regarding PFAS and lithium management, fine-tuning community engagement/education efforts, and for private sector industries seeking to get a handle on potential liabilities. SCS Engineers and other qualified environmental firms are poised to be essential partners to national leaders in identifying and remedying emerging contaminants such as PFAS. Many technologies proven to work on a large scale are available, with more promising technologies on the horizon.

Illinois EPA Updates NPDES General Industrial Permit

August 11, 2023

NPDES General Industrial Permit
Industry sectors must update site-specific SWPPPs to comply with the 2023 NPDES General Permit. Here’s how.

 

On July 1, 2023, the Illinois Environmental Protection Agency (IEPA) posted and updated General NPDES Permit No. ILR00 for Industrial Storm Water Discharges (2023 General Permit). The 2023 General Permit is effective July 1, 2023, through June 30, 2028.

Multiple industry sectors must now update their site-specific Storm Water Pollution Prevention Plan (SWPPP) to comply with the 2023 General Permit. Three key updates in the 2023 General Permit are:

1-Permittees are required to submit a Notice of Intent (NOI) for renewal no later than 150 days after the 2023 General Permit is issued (i.e., by November 28, 2023).

2-Permittees must place a sign of permit coverage (except in instances where other laws or local ordinances prohibit such signage) in a safe, publicly accessible location in close proximity to the facility and include the following:

      • The NPDES ID Number;
      • Information about how the public can request the facility’s SWPPP; and
      • How to contact the facility and IEPA if stormwater pollution is observed.

3-Benchmark sampling requirement updates, varying based on the industry sector’s Standard Industrial Classification (SIC) Code classification:

PADEP Alert: NPDES General Permit for Industrial Stormwater Discharges

January 31, 2023

SCS Engineers
The Pennsylvania Department of Environmental Protection – NPDES Regulatory Updates with Deadlines

 

On December 24, 2022, the Pennsylvania Department of Environmental Protection (PADEP) published the renewed NPDES General Permit for Discharges of Stormwater Associated with Industrial Activity (PAG-03). This permit covers stormwater discharges from industrial facilities such as manufacturing facilities, landfills, scrap yards, and bus terminals.

 

Facilities with an existing General Permit must submit a Notice of Intent (NOI) to be covered under the reissued General Permit by March 23, 2023. Stormwater Discharges.

 

The new permit term will cover operations from March 24, 2023 (effective date) to March 23, 2028 (expiration date). If PADEP receives an NOI by March 23, 2023, an existing PAG-03 permittee can continue to discharge under the reissued PAG-03. The application forms and instructions are available from the PADEP eLibrary.

Beginning in 2024, the due date of the Annual Report and NOI fee annual installment payment will be by March 23 each year. For existing permittees, the due date for the NOI fee installment in 2023 and the annual report covering 2022 will be May 1, 2023.

Analytical requirements for monitoring stormwater discharges are established in an appendix to the General Permit for each industrial sector. A monitoring requirement for Total Nitrogen and Total Phosphorous was added to each Appendix. Other changes made are to monitoring and Benchmark Value parameters for individual sectors. Target Quantitation Limits (TQLs) are established for analytical parameters, and permittees must use labs that can meet the TQLs to comply.

The new permit increases response levels for continual exceedances of Benchmark Values, concentrations of pollutants that serve as a threshold for evaluating whether site Best Management Practices effectively control stormwater pollution. Two or more consecutive monitoring period exceedances of Benchmark Values trigger the requirement to develop and submit a corrective action plan, implement additional controls, or apply for an individual permit if notified by PADEP.

Monitoring under the renewed permit commences with the July 1 – December 31, 2023 monitoring period. Until July 1, 2023, permittees should continue monitoring for parameters in their existing General Permit.

These are not the only changes made to the General Permit. Please contact for updates in other states or commonwealths and Denise Wessels at (610) 382-3050 if you need help preparing the NOI to reapply for the permit or to maintain compliance with permit terms in Pennsylvania.

Ryan Duckett, President of the Virginia Chapter of the US Composting Council

April 30, 2021

 

The Virginia Composting Council is the state affiliate of the US Composting Council; its mission is to support the efforts and initiatives of the USCC and bring the practice of composting to more Virginians. The Composting Council is growing because of increased efforts by communities to divert food waste from disposal. Demand is growing with increased awareness of composting’s beneficial uses.

The Virginia Council, led by President Ryan Duckett of SCS Engineers, cites the obvious benefits of less waste going to landfills and lower greenhouse gas emissions in the environment. He also points out the jobs and business development potential and using compost for stormwater management, erosion control, and other green infrastructure as benefits. Expanded programs also offer the opportunity to collect edible foods for non-profits feeding many in need while diverting non-edible organics to composting.

The Council brings together manufacturers, municipal managers, organics collectors, researchers, and other compost allies in the waste industry. The group works to educate state regulators, local officials, and the public about composting’s value in a circular system. Members also help develop positions on regulations and legislation that affect composting and the market.

USCC has 13 state chapters that do local work to advance the composting industry alongside the national advocacy and programs. Without their on-the-ground education, attention to and work in regulations and legislation, and building networks of people in the industry, USCC could not be effective.

Learn more about composting.

 

Our congratulations to Ryan and the entire USCC for the help and support they bring to our communities.

Brownfields/Remediation: Solary Park, From Florida Brownfield to Multi-purpose Community Asset

April 5, 2021

SCS’s technical expertise was crucial to successfully remediating this site, attests Bobby Wyatt, Public Works Director at City of Oviedo, Florida.

 

Cities like Oviedo, Fla. are investing in the cleanup of defunct brownfield sites, converting even highly contaminated properties from liabilities to assets that pump economic vitality into their communities. And municipalities are getting reimbursed for doing so. But these ambitious undertakings require the expertise of professionals with strong environmental engineering and remediation backgrounds and an understanding of federal and state regulations aimed to protect public health and the environment.

This spring, after over two years of working closely with SCS Engineers and the development team, the City of Oviedo will unveil its redevelopment project: a 3.7-acre public park with a walking and jogging trail. The loop trail will be part of a larger trail system interconnecting through the City and the Cross-Seminole trail, with the latter running throughout the county.

The walking and jogging path surrounds a pond with a dual purpose: to serve as an added feature to this peaceful retreat and part of an enhanced stormwater management system that will allow business owners to convey drainage from their properties via an underground stormwater management system. Along the park perimeter, historical displays will tell the story of the nearly century-and-a-half-old City’s past.

SCS helped the City navigate regulatory issues associated with redeveloping environmentally impacted land, ensuring safe and environmentally sound practices, and maximizing financial reimbursement through the Florida Brownfields Program.

In the 1940s, the site operated as a farm but lay idle and overgrown with vegetation decades after. When SCS came in to complete the environmental assessment, the team confirmed that years of pesticide application did leave arsenic behind in the soil.

“It appears that the pesticides were used appropriately, but with the change in land use and to meet the state’s environmental criteria, we need to address the residuals to redevelop the property as a park. It would otherwise remain as unusable land without this cleanup,” says Kirk A. Blevins, SCS senior project manager.

SCS completed site assessment activities according to Chapter 62-780 FAC, which includes additional testing to delineate the extent of arsenic-impacted soil further and evaluate groundwater conditions. Assessment activities indicated that while not impacting groundwater, the soil contained arsenic above acceptable regulatory levels. In its next step, the team designed a remedial action plan with multiple considerations for success.

“Given that the site would include both a stormwater management pond and a public park, we recommended that rather than cap the soil to reduce potential exposure, the City meet the strictest cleanup criteria. This option is the most protective of human health and the environment,” Blevins says.

The plan included removing approximately 47,000 cubic yards of arsenic-impacted soil, then placement of clean import fill for areas open to the public. Blevins and his team proposed excavating to the property boundary, and they provided technical guidance to the City contractor on how to efficiently and safely execute this undertaking. “It was important to excavate to the property boundary to assure removal of the impacted material so that the City would receive unconditional closure approval from the regulatory agency,” explains Blevins.

Concise reporting of the work is key to securing that approval, so SCS documented the excavation of impacted soil to the appropriate depths and lateral extents, managing it appropriately onsite, and transporting it to an approved landfill for disposal.

The team worked with the City’s environmental counsel to bring the site into the Florida Brownfields Program and prepared its voluntary cleanup tax credit (VCTC) applications for submission to the Florida Department of Environmental Protection (FDEP). All expenses and payment, confirming the expenditures “integral to rehabilitation,” are documented. With this validation, the City of Oviedo is getting back about half of its $1,432,000 related investment. It will receive another 25% bonus once FDEP issues a letter stating that no further action is required.

Documentation and communication with the state regulators is an ongoing process requiring a detailed review of contractor proposals, invoices, pay applications, proof of payment, and a summary of progress each year over the project’s life. “In particular, a line-item review of invoices can sometimes establish additional actions that are critical to remediation that otherwise might have been overlooked and not captured. This process is vital to maximize reimbursement,” Blevins explains.

Cost, as always, is a client priority. So, SCS and the remedial team focused on minimizing offsite disposal of the impacted soil, proposing over-excavating the pond, using the unimpacted soil as the onsite fill, and placing a portion of the impacted soil at the pond’s bottom.

“This was possible because testing indicated that the impacted soil would not leach arsenic into the pond water at a rate that would adversely affect water quality. We confirm that arsenic concentrations are below the strictest regulatory level before any soil from over-excavating the pond can be of beneficial reuse onsite. Safety of people and environmental protection always comes first,” Blevins says.

The ultimate outcome: Oviedo has a regional stormwater pond suited for potential commercial operations to use for drainage, maximizing available land for economic development, as well as a recreational park for the community and visitors.

SCS’s technical expertise was crucial to successfully remediating this site, attests Bobby Wyatt, Public Works Director at City of Oviedo, Florida.

“The team easily navigated and sped up the permitting process for the arsenic removal and provided continuing assistance with monitoring during construction. The process for completing the specific remediation/permitting was unfamiliar to City staff, and SCS provided efficient and competent assistance to get us where we needed to go.

Their experience provided a sense of confidence that we were going to be able to make the park project successful,” Wyatt says.

 

SCS has worked on brownfields projects and voluntary remediation across the U.S. for over 45 years. We convert once nonproductive commercial and industrial properties into revenue-generators and affordable housing.
