Why the California State Water Boardconsiders B100 a hazardous substanceCalifornia statutes have NO de minimus limitationsASTM D6751-07a allows up to 0.5% Methanol,--- which is a “hazardous” substanceOut of spec biodiesel may contain “hazardous”peroxides …unless antioxidants have been added… however, antioxidants are themselves usually“hazardous” substances
10 ways BIODIESEL may reduce materialstability in UST systems –and what to do about it<strong>Biodiesel</strong>:1. Is more electrically conductive; avoid vulnerablemetals and water2. Is vulnerable to oxidation: avoid off-spec fuel, water,and “old” fuel (biodiesel not recommended forstandby generators)3. Has been frequently contaminated: insist onguarantee of ASTM D6751 fuel quality
