Renewable Fuel Standard Renewable Identification Number Verification Services

The Washington Suburban Sanitary Commission (WSSC) is seeking a qualified third-party consultant to provide comprehensive Renewable Identification Number (RIN) verification services for its Bio-Energy facility located at the Piscataway Water Resource Recovery Facility (WRRF) in Accokeek, Maryland. The facility produces renewable natural gas (rNG) from anaerobic digestion of wastewater sludge with an estimated production capacity of approximately 12 MMBtu/hr, supplies rNG for use as vehicle fuel by a local bus fleet, and injects rNG into the natural gas distribution system operated by Washington Gas.

The consultant will be responsible for developing and implementing a RIN Quality Assurance Program (QAP) in accordance with the Environmental Protection Agency (EPA) Quality Assurance Plan, performing ongoing verification services, and ensuring compliance and marketability of Renewable Identification Numbers. The produced fuel is expected to generate D3 (Cellulosic) RINs under EPA-approved pathways.
