RINs Verification Engineering Review Report for Dos Rios Water Recycling Center

RINs Verification Engineering Review for Dos Rios 1

First Environment support Element Markets with an engineering review of the San Antonio Water System’s recovery and conversion of biogas produced from the Dos Rios Water Recycling Center into transportation fuel. The biogas is treated onsite at the wastewater plant and injected in a commercial pipeline transferring it to a Liquefied Natural Gas (LNG) conversion plant located in Topock, Arizona, as well as to several Compressed Natural Gas (CNG) fuel stations. The LNG fuel is then transported by truck into California for use in trucks and buses. The CNG is dispensed directly by each CNG station for use as transportation fuel, usually by truck and bus fleets. The project qualifies to earn tradable Renewable Identification Numbers (RINs) under the Environmental Protection Agency’s (EPA’s) Renewable Fuel Standard (RFS2) program.

First Environment performed the engineering review services required under RFS2 in order to register the activity with EPA and qualify to generate the tradable RINs associated with fuel production and use as transportation fuel.

First Environment performed the required site inspection visits and review of technical and contractual documentation pertinent to project activities. We submitted an Engineering Review Report to EPA to validate the project’s application for registration.

Once approved, the project will be able to earn 2.3 million RINs per year and avoid the use of 1.5 million gallons of diesel fuel annually, which is equivalent to approximately 15,000 metric tonnes of CO2 emissions each year.
