Yes. Rush services are available to support critical deadlines.
Yes. We review your specific pipeline specs and permit conditions to align the test panel and sampling plan
Pipeline tariffs set gas quality specs for product gas. (requirements vary, but often include methane purity, sulfur, oxygen, siloxanes, moisture, and heating value).
Your air permit, state program, or credit programs like EPA Renewable Fuel Standards may require additional analytes and frequencies as well as testing of your raw biogas. We align your panel with both the pipeline and permit.
