SCS Engineers Named a Premier Ignition Integrator

December 4, 2019

Inductive Automation® announced the software firm now recognizes SCS Engineers as a Premier Integrator. Premier Integrators have a high level of commitment, professionalism, and competency using the Ignition software. They must consistently produce high-quality work and must consistently demonstrate successful projects with very satisfied end-users.

SCS uses Inductive Automation’s Ignition supervisory control and data acquisition (SCADA) software in their solution because it is a proven state of the art software, which works well with cloud-based systems and the internet of things (IoT). It allows clients to easily control, track, manage and report on their processes.

Large landfills, counties with multiple landfills, and private waste management firms have been waiting several years for SCADA software to catch up to their business needs. Landfill operations are extremely complex and expensive since they monitor and manage multiple systems to protect the public from contamination to the air, water, or soil. There are typically multiple operations active on many sites, such as waste recovery, recycling, composting, Gas Collection and Control Systems (GCCS), and renewable energy plants.

SCS Remote Monitoring and Control®, or SCS RMC® provides a next-generation option to monitor and control systems, and see the data collected and the systems in action. It allows users to control their systems remotely, collect data and use the data to enhance their productivity, reduce their operations and maintenance (O&M) costs, and reduce their environmental risk. Other offered services include 3D imaging from drones and virtual reality (VR). SCS uses aerial data collected via drones to compose topographic mapping, 2D images, 3D renderings, GIS, thermal, infrared (IR), and methane leak detection for waste facilities. The SCS RMC® team can take rendered models and apply them into virtual reality (VR) headset as well, which allows decision-makers at waste management facilities and organizations to “walk the site” from anywhere.

 

Current clients save Operating & Monitoring (O&M) costs and reduce human error by generating internal and regulatory reports automatically, using data automatically collected by the system. They can also receive instant notification of malfunctions and can troubleshoot these notifications remotely.

Not only for landfills, until recent years the public did not realize the long-term value of recycling nor the associated costs. Some clients use SCS RMC® to monitor dumpsters and recycling receptacles for collection. This helps keep waste and recycling inside the container, collection schedules more efficient, and overall operations less costly.

Manufacturing, industrial facilities, and ports use remote monitoring and control for real-time viewing, analysis, and control of equipment and systems critical to production and safe operations, often for air monitoring.

Galen Petoyan, Senior Vice President of Field Services states, “We fully embrace SCS RMC® within SCS Field Services® because the software allows us to provide more value to our clients; our technicians and engineers can avert problems, and when needed, provide rapid, efficient, and accurate analysis and action.”

Q&A with Ali Khatami – Jet Cleaning Leachate Collection Pipes

August 21, 2019

I read your informative blog regarding recommendations for jet cleaning leachate collection pipes. I have a question.

QUESTION: Say a landfill only has access to one end of a leachate pipe. This would be a situation where a new cell was built, where the uphill side of the cell butts up against an existing, pre-subtitle D cell with no leachate collection pipe. In other words, the uphill side of the new leachate pipe simply terminates rather than tie into an existing pipe.

To add to the issue, no vertical cleanout/riser pipe was installed on the uphill end (as this may impede waste operations in the area). There are of course riser and cleanout pipes and a sump on the downhill side for normal leachate collection. I would imagine that pumping water from the accessible side would push out any solids through the perforations into the leachate aggregate bedding, and may cause clogging there.

 Is it possible, or reasonable, to flush this new leachate line?

 

ANSWER: There is always a possibility that a portion of dislodged material from the interior walls of the pipe will pass through pipe perforations and enter the gravel bedding around the pipe. However, due to the pipe slope, the great majority of the separated material flows down the pipe to the lowest point where it can be removed using a vac-truck.

Keep in mind also that, it’s true that leachate can partially flow through the bedding gravel toward the sump, but the role of the gravel is primarily protecting the pipe against compressive loads of waste above. Partial clogging of gravel around the pipe should not be considered as a malfunction of the system. Partial clogging of gravel normally may occur near the bottom portion of the gravel pack, which still allows leachate flow through gravel to pipe perforations above any clogged zone below.

In several instances, when a portion of a leachate collection pipe was opened up after being in service for a while, it did not support the idea of a clogged zone in the gravel pack. What was observed, included discolored gravel due to fine particles settling (from filtered leachate through geotextile) on gravel particles and a bit of the same particles near the bottom of the gravel pack.

I’ve never observed severe clogging of the gravel pack.

Determining if Deep Well Injection is a Viable Technology for Your Facility

June 17, 2019

Understanding the entire range of wastewater management and disposal alternatives can be a daunting task, particularly as increasingly stringent surface water discharge standards take effect or as zero discharge facilities find the management of their waste liquid needs changing over time. Former solutions are no longer options or may be too costly. One alternative that is rapidly gaining traction is deep injection wells.

Deep well injection is a viable leachate management option in many parts of the United States, yet it is often screened out as a possible alternative due to a lack of understanding of the technology or gross misconceptions about its acceptance or applicability. The purpose of the Monte Markley’s paper The Basics of Deep Well Injection as a Leachate Disposal Option  is to present the basic technical, economic and regulatory considerations of deep well injection as a technology a facility should evaluate when considering the applicability of geologic sequestration of leachate.

Technical criteria discussed are potential disposal volumes, geologic suitability, chemical compatibility, pre-treatment requirements, and leachate chemistry. The economic considerations are evaluated based on the technical criteria noted above, management of public perception/relations, current leachate management expenditures, the service life of the asset and risk to develop accurate capital, O&M costs, and return on investment. Regulatory considerations include the role of state vs. federal primacy for each state, the general stance of regulatory acceptance in specific areas of the United States,  and a discussion of the permitting process and typical reporting requirements.

These key considerations are then integrated into an overall suitability evaluation that an owner can utilize to accurately determine if deep well injection is a viable option and, if so, how to educate other stakeholders and manage the process of implementation as a project moves forward.

Volusia County Selects SCS Engineers for Green Capital Improvements

May 15, 2019

County of Volusia’s green capital improvement plan supports sustainable solid waste management.

More than 500,000 people call Volusia County home. Situated on the east coast of Central Florida, the county has 47 miles of Atlantic Ocean beaches and beachfront cities including Daytona Beach, Ormond Beach and New Smyrna Beach. Volusia County has an abundance of natural beauty and some of the most beautiful parks in the United States.

Green Volusia is the county’s long-term initiative designed to provide residents and visitors with information about green, or sustainable, practices to reduce the impact on the environment. Green Volusia provides information about environmentally responsible practices that benefit the whole community as well as encouraging stewardship and conservation of our natural resources.

Despite the best green practices, it came time to expand the county’s landfill. The City Council approved a contract for Professional Construction Quality Assurance (CQA) and Engineering Services with SCS Engineers. SCS is an award-winning environmental consulting, engineering and construction company known for sustainable environmental solutions. The Council selected SCS for their in house expertise in MSW cell construction, and successful record of delivering the highest quality environmental engineering services.

Federal Judge Rules Against EPA on the Landfill EG Lawsuit

May 10, 2019

Before the Court: EPA admits that it has failed to meet its nondiscretionary obligations to implement the Landfill Emissions Guidelines, as compelled by the CAA. The only questions before the Court were whether the Plaintiffs have standing and, if so, how long to give EPA to comply with its overdue nondiscretionary duties under the Landfill Emissions Guidelines. The Plaintiffs are the States of Illinois, Maryland, New Mexico, Oregon, Rhode Island, California, Vermont, and the Commonwealth of Pennsylvania.

Ruling: Plaintiffs have standing, and the EPA must approve existing submitted plans by September 6 and issue the federal plan by November 6.

Impact on Landfill Owners/Operators: This will create some confusion, as landfills will be working on getting revised rules in place while at the same time start complying with the old EG rule. We are already doing that with XXX sites, but this ruling adds complexity. If EPA keeps to the schedule and we have final approved revised rules by March 2020, landfills won’t have to do as much under the old rules before new ones take effect.

Stay tuned.

How Future Use Guides Ash Pond Closure Strategies – WOCA 2019

April 18, 2019

World of Coal Ash in St. Louis, May –13-16, 2019 event details.

Even the simplest impoundment closures come with design challenges. It is a challenge to navigate project constraints, whether technical, regulatory, or financial, to design and implement an effective closure strategy. Cost often helps to determine the “balance” between project constraints when the future end use of a closed CCR surface impoundment or the property it occupies is undefined. When a post-closure end use is defined, finding balance among project constraints to best serve that future use provides rewarding challenges.

SCS Engineers has navigated this balancing act on impoundment closure projects during facility decommissioning. Through a presentation of case studies, you will learn how this team has approached ash pond closure planning and execution where the future use of the impoundment site ranged from undefined to the home of a new solar photovoltaic installation. Examples also include potential future industrial use or property sale.

Case studies will highlight how geotechnical, hydrological, regulatory, or simple physical constraints have influenced the design and implementation of CCR surface impoundment closures.

State vs Federal CCR Rule Regulations: Comparisons and Impacts

March 28, 2019

World of Coal Ash in St. Louis, May –13-16, 2019 event details.

When the Federal CCR rule went into effect in 2015, it was a new regulatory layer on top of a widely varying landscape of state regulations affecting CCR management in impoundments and landfills. Some states already had significant regulations on the books for CCR impoundments and/or landfills, while others did not. Where state regulations existed, they varied widely from state to state. While a few states have moved toward closing the gap between state and federal CCR requirements, many utilities continue to face confusing and conflicting requirements coming from different regulatory programs as they move ahead with managing their CCR facilities.

Through case studies, SCS Engineers will share state-versus-federal regulatory challenges utilities have encountered in different regions of the country during landfill design and management, impoundment closure, and groundwater monitoring and reporting since the implementation of the Federal CCR Rule. For example, some sites have completely distinct groundwater monitoring programs under state versus federal rules, with different well locations, well depths, and monitoring parameters for the same facility. We will highlight unique approaches to bridging regulatory gaps and resolving regulatory conflicts between state and Federal CCR requirements.

SCS will also share insights gained on the long-term potential for regulatory resolution of these issues based on discussions with state regulators in multiple states.
