Transfer Facility Siting, Design and Permitting

EnSol has successfully sited facilities and modified permits for existing solid waste transfer and processing facilities. Types of regulated material managed in the permit and design process at transfer facilities have included general municipal solid waste, construction and demolition debris and various recoverable recyclable materials. Design and permitting services provided include facility sizing, process engineering, process controls and maximization of storage within physical and regulatory constraints.

Operations Engineering

EnSol maintains field staff trained in solid waste management facility operational consulting. Our staff is experienced in the review, preparation and implementation of operational controls and performance criteria necessary for effective facility management. EnSol manages on-site personnel and conducts regular operational meetings at facilities. This provides the opportunity to discuss and modify facility operational techniques in order to maximize waste throughput in a manner that affords safeguards to the environment while increasing revenue.

Post Closure Maintenance, Monitoring and Reporting

EnSol has developed cost-effective post-closure facility monitoring and maintenance programs that effectively ensure safeguards to the environment, while meeting stringent governmental controls and regulations. Our plans ensure continued compliance with regulatory requirements throughout the entire post-closure period. This may include scheduled site visits to investigate the condition of monitoring points, drainage areas and in the case of landfills, the integrity of the final cover system.
Findings from site visits, as well as laboratory analytical data from scheduled monitoring events, are reviewed and discussed in quarterly or annual reports submitted to the appropriate regulatory agency.

Facility Siting, Design and Permitting

EnSol is proficient and experienced in siting criteria, design, and the permitting process for hazardous waste management facilities. A site may be subject to restrictions based on its proximity to wetlands, flood plains, aquifers, sensitive adjoining land uses or other conditions, which can often be resolved through innovative design features. Our diverse and knowledgeable staff is capable of effectively coordinating the expertise of attorneys and involvement of government officials in ways that maximize capital investments and reduce long-term risks. EnSol has successfully guided projects through the permitting process to the satisfaction of our clients and all regulatory agencies and, at the same time, provided safe and cost-effective landfill design alternatives.

Remedial Investigations and Feasibility Studies

With more than ten years of experience in developing remedial alternatives for existing, non-compliant disposal sites, EnSol staff members are well equipped to determine the most cost-effective remedial alternative, and implementing the remedy to protect the welfare of the environment and citizenry pursuant to regulatory mandates and time frames. EnSol develops Work plans that are custom-tailored and guides a client from the status of a principally responsible party to that of an environmentally responsive party. Our experience allows for the cost-effective and timely implementation of remedial measures to ensure the satisfaction of adjacent landowners, citizens, regulators and most importantly, to the satisfaction of our client.

Site Reclamation and Re-Use

Wherever possible, given the regulatory climate for the reuse of lands only mildly contaminated in the 'Brownfields' approach, EnSol develops environmentally responsible options for reclaiming lands without the costly remedial or rehabilitative efforts that are often automatically prescribed. EnSol thoroughly evaluates site information, history and analytical data to make the demonstration, where appropriate, that the site can be reused or reclaimed for a secondary, compatible use. Using the best and most appropriate available technologies, EnSol makes technical demonstrations supporting the proposed secondary land use. EnSol guides the client through regulatory mandates in the pursuit of reclaiming or reusing a site that was previously deemed 'hazardous'.

Hazardous Waste Post Closure Maintenance, Monitoring and Reporting

Owners/operators often continue to maintain on-site operations and support infrastructure after a hazardous waste management facility has closed. However, meeting post-closure obligations and responsibilities does not always necessitate the need to maintain presence, equipment and employees at the site. EnSol has allowed owner/operators in several states to close facilities while keeping only financial mechanisms and arrangements in place to address any post-closure needs. Whether administering the post-closure monitoring program, inspecting and verifying cover integrity, or maintaining storm water controls, EnSol allows clients to focus efforts and resources on their company’s next endeavor while providing post-closure care services. The provision of these services, from monitoring well sample collection to quarterly and annual reporting, allows the freedom to develop other business interests without being distracted by the demands of a closed facility.

Facility Inspection Services

EnSol performs the following activities for facility inspection:

  • Site inspection
  • Grounds keeping
  • Maintenance and upkeep of storm water control system
  • Cap cover repairs
  • Access control
  • Contingency management

Environmental Monitoring and Reporting

All landfill operators are required to monitor the surrounding environment during operations, closure and post-closure phases in order to protect human health and the environment. Site-specific Environmental Monitoring Plans are prepared that outline the media that must be sampled and analyzed. Existing water, soil or air quality is determined as part of the preparation of the EMP, and compared to subsequent water quality data collected during scheduled monitoring events. EnSol will coordinate all monitoring activities and review analytical data before submitting all required documentation to the appropriate regulatory agencies.

Leachate Collection Services

Maintenance and operation of leachate collection systems is required during active, closure and post-closure periods as long as leachate is being generated. EnSol will perform the following activities:

  • Tank testing and certification
  • Maintenance of pipes, pumps and controls
  • Sampling and data review
  • Record keeping and reporting
  • Leachate disposal
  • Corrective action

Gas Management Services

Landfills present unique problems in that they are subject to settling, leachate seepage, and continuously varying gas makeup. EnSol, Inc. offers specialization in the recovery of methane gas from landfills for the purpose of creating profitable and environmental benefits by using the landfill gas (LFG) as an alternative energy source. Our experienced team has the know-how to design and manage a LFG-to-electricity system to overcome these problems, both in the office and in the field.

The implementation of a LFG-to-electricity system involves four main areas: gas wells, LFG collection system, gas scrubbing system, and gas engines and electrical switchgear. After installing the gas wells and LFG collection system, the quantity of gas is monitored so that the correct size LFG-to-electricity plant can be determined. Our experience in this area is key to the overall success of the LFG-to-electricity system.

EnSol, Inc. works closely with Innovative Energy Systems, Inc. in providing the gas management services required for gas collection and electrical generation. Innovative Energy Systems, Inc. (IES) has Corporate Headquarters located in Clarence, New York with two subsidiary firms: LFG Energy, Inc., located in Lancaster, New York; and Seneca Energy, Inc., located in Seneca Falls, New York. LFG Energy, Inc. and Seneca Energy, Inc. own and operate 6.6 MW and 11.2 MW LFG to electricity facilities, respectively.

IES President Peter H. Zeliff and his qualified staff have developed proven technology that enables the company to provide turnkey design, well drilling services, and fully constructed systems for the use of recovering landfill gas in a cost effective and profitable manner. IES strives to provide the best available technology and prides itself on industrial knowledge.

Once the plant size has been determined, IES will construct a gas scrubbing system and the generating plant. Their proprietary gas scrubbing system is the key to ensuring the life of the gas engines and the plants operating viability. This is because LFG contains water, particulate, and acids that harm the gas engines. The gas engines, generator sets and associated electrical switch gear come as a complete set from Caterpillar, Inc.

EnSol has the capability of providing all design, engineering, construction, manufacturing and administrative services necessary in a complete turnkey package. EnSol employs experienced and qualified technicians to properly assess the hazards that landfill gas creates.

EnSol, Inc. utilizes proprietary technology with respect to LFG wells, LFG collection systems, LFG scrubbing systems and LFG-to-electricity plant design. This technology has been developed by Innovative Energy Systems, Inc. (IES). IES is a New York State Corporation that specializes in landfill gas recovery systems. EnSol, working with IES, installs all components of a LFG-to-electricity system and will manage and operate the system.

EnSol’s experience, combined with IES’s proprietary technology, produces a quality plant that is cost-effective and proven in reliability.
