Biogas & RNG Field Services
On-site Sampling, Compliance Testing, and Gas Quality Verification
Ohio Lumex provides expert field services for biogas and Renewable Natural Gas (RNG) producers, pipeline operators, virtual pipelines, utilities, and more. Our certified field technicians deliver reliable on-site sampling per the methods to support compliance with pipeline RNG gas quality specifications, the EPA Renewable Fuel Standard (RFS), and the 45Z tax credit (ASTM D8080), process control, upgrading design and specification, and others.
Ensure Accurate Results from Site to Specification
Biogas and RNG operations come with complex regulatory and commercial requirements. Whether you’re preparing for pipeline injection, EPA Renewable Fuel Standard (RFS) reporting, tax credit qualification under 45Z (ASTM D8080) or specifying upgrading equipment, accurate field data is critical. Improper sampling or handling can lead to unreliable results, non-compliance, production delays, or missed incentives.
At Ohio Lumex, our experienced field service team understands the unique challenges of gaseous fuels. We provide trusted on-site support that delivers actionable, defensible results.
Supporting facilities including:
- Agricultural digesters (dairy, hog, farm waste)
- Landfills and landfill gas
- Wastewater treatment facilities
- Food waste co-digestion facilities
- Commercial RNG producers
- Utilities and pipeline injection projects
Aligned with Industry Standards and Regulatory Programs
Field sampling and gas quality verification must meet rigorous industry and regulatory requirements. Ohio Lumex integrates applicable standards into our field process, including:
- EPA Renewable Fuel Standard (RFS) reporting requirements
- Pipeline quality specifications (e.g., interconnect requirements)
- 45Z tax credit eligibility testing (ASTM D8080)
- Relevant ASTM sampling and handling protocols
- Custom client specification compliance
Because sample integrity drives the quality of lab results and downstream decisions, we design our field processes to support reproducibility, defensibility, and regulatory acceptance.
Comprehensive On-Site Services
On-Site Biogas & RNG Sampling by Certified Field Technicians
Our certified field technicians perform systematic, standards-aligned sampling across digesters, storage wells, process lines, waste gas, product gas, and CNG trucks. Following established methods and best practices, we capture representative gas samples, maintain sample integrity, and deliver defensible data with full documentation and chain-of-custody.
Gas Quality Verification
We evaluate all the required analytes, including:
- Major gases and hydrocarbons
- Mercury, ammonia, aldehydes & ketones
- Total & speciated sulfur compounds
- Volatile Organic Compounds (VOCs)
- Siloxanes
- Toxic metals
- Biologicals
- Moisture, temperature and other onsite tests
- Radiological testing (radon, alpha & beta)
- Carbon-14
- Others
Results provide confidence in gas quality for pipeline disposal or RNG certification.
Compliance Testing
We conduct compliance sampling for:
- Pipeline interconnect specifications
- EPA RFS reporting requirements
- Contractual quality requirements for offtake agreements
All sampling is documented with a chain-of-custody and field notes for audit-ready results.
