NTH has been providing professional consulting services to RNG facilities nationwide. Our experienced and dedicated team brings unmatched regulatory expertise and understanding of RNG process conditions to provide a streamlined approach to facility siting, environmental permitting, process safety, and risk management, whether derived from agricultural or landfill gas, NTH understands the RNG Market, processes, and requirements for a successful project.
Process Safety & Risk Management
State and federal Occupational Safety and Health (OSHA) regulations require that many of the RNG processing facilities comply with the regulations for Process Safety Management (PSM) of Highly Hazardous Chemicals, as well as U.S. Environmental Protection Agency (EPA) Chemical Accident Prevention Provisions, otherwise known as Risk Management Plan (RMP). These regulations govern design, operation, and maintenance of processes with highly hazardous chemicals, such as RNG facilities. NTH has prepared several PSM and RMP manuals, including facilitation of process hazard analyses (PHAs), for submission to U.S. EPA. Following the facility’s construction and operation, NTH assists our clients with regulatory compliance, including PHA updates and routine third-party required audits. Landfill Engineering
The siting, design and construction of a sanitary or hazardous waste landfill is a complex process. Furthering the intricacies of such a project are the increasingly stringent federal and state regulations for the design, construction, and operation of landfills. Expertise in siting, design, and construction monitoring is vital to developing a quality facility that meets regulatory requirements and community scrutiny. NTH has provided consulting assistance in the siting, permitting, design and construction, as well routine regulatory compliance for active and closed landfills for more than four decades. Our clients have included major landfill companies, municipalities, and independent landfill operators. We employ specialized expertise to assist with landfill site selection, site design, leachate management and associated emerging contaminants BMPs, gas control systems, construction, closure, and post-closure monitoring.
Environmental Permitting & Compliance
Our Environmental Team is experienced in navigating state and federal regulations that govern siting, emissions, and releases from RNG production equipment, including digesters and/or lagoons, process skids, and supporting equipment such as boilers, flares, and thermal oxidizers. Air permitting and ecological studies for RNG production can present challenges related to the variable nature of production and each is critical to maintaining flexibility while meeting health-based standards, carbon footprint, with project timing constraints. We also have expertise using computer dispersion models to evaluate localized exposure levels associated with potential releases from the biogas equipment. |

“NTH’s attentiveness to detail and review of the RNG design process has helped our project team arrive at relevant design outcomes that impact the safety and success of each unique project.” Civil / Geotechnical
Geotechnical engineering is the foundation of all constructed facilities, including RNG facilities and associated digesters and outbuildings. Since NTH began as a geotechnical engineering firm over 53 years ago, our extensive geotechnical expertise confirms that projects are appropriately designed – mitigating excessive costs associated with over-design and preventing failures caused by under-design. Our extensive subsurface evaluation process consists of:
