FEATURE What, Another Deadline? Department of Environmental Protection secondary containment deadline Marshall Mott-Smith lmost everyone knows about the Dec. 31, 2009, Florida Department of Environmental Protection secondary containment deadline for underground tanks that will soon be upon us. However, many people are completely unaware of a new deadline on the horizon. This new deadline will aﬀect owners of storage tank facilities that store and market diesel fuel, and create a need for a whole new infrastructure. This new deadline comes from a requirement for improving air quality by reducing nitrogen oxide and particulate emissions from diesel engines. The U.S. Environmental Protection Agency has established stringent new standards, but has left the control strategies up to the industry on how to best achieve the standard. Beginning on Jan. 1, 2010, any new diesel engine that comes oﬀ the assembly line (in all eight classes) must be equipped with new technology to meet this new EPA requirement. Th is will include original equipment manufacturers such as Detroit Diesel, Volvo Mack, Paccar, Cummins, Hino, Isuzu, Ford, GM, Mercedes Benz, BMW, Chrysler and all others. The technology to meet the 2010 EPA Clean Air Act requirement is called SCR (Selective Catalytic Reduction). It will eventually replace EGR (Emission Gas Reduction) technology when every vehicle and vessel with a diesel engine has SCR technology. SCR technology relies on the injection of DEF (Diesel Exhaust Fluid) after engine combustion but prior to the SCR Catalytic Converter. A dosing valve will inject the DEF into the exhaust waste gas stream. After passing through the catalyst, the waste gases are converted to nitrogen gas, water and small amounts of carbon dioxide. See the diagram top rightl; excerpted from www. factsaboutscr.com. DEF is a mixture of two thirds de-ionized water and one third urea. DEF cannot just be batch-mixed on site. It is critical that DEF be manufactured to ISO 22241-1 standards using high purity urea liquor with high purity de-ionized water. The purity must be maintained along the supply chain as well. In addition, DEF is sensitive to temperature extremes and should be stored 25–90 F to maintain product quality. DEF starts to gel at about 25 F, and will begin to deteriorate if temperatures remain above 90 F for more than a month. DEF is alkaline and will corrode soft metals, and ﬁberglass is not compatible, so compatible products such as plastics, polyethylene, rubber A and stainless steel must be used in the storage and dispensing systems. Although 80 to 90 percent of the urea used in the United States is used in dry form for fertilizers, there are no problems with urea supplies needed to meet the new market demands for DEF. DEF is non-hazardous and should not be a signiﬁcant problem when spilled, but care should be taken to keep spilled DEF out of surface waters. The Material Safety Data Sheet for DEF recommends that spilled product be recovered and used as fertilizer. Nevertheless, DEF storage over 1,000 gallons should be included in a company’s Surface Water Pollution Prevention Plan (SWPPP). This is especially important with transportation companies because they are speciﬁcally mentioned in the SWPPP standards for Best Management Practices. Although it is not currently a requirement, storage facilities with over 1,000 gallons capacity should be secondarily contained. How will this aﬀect the petroleum marketing industry in Florida? First of all, vehicles manufactured with new diesel engines after Jan. 1, 2010, will be equipped with SCR technology. This will include a normal onboard diesel storage tank and a new onboard tank for DEF. Vehicle use will vary, but the DEF onboard storage capacities will be between four and ﬁve gallons for passenger vehicles, and 15–25 gallons for trucks. For the ﬁrst year, demand will be low. However, as more SCRequipped diesel vehicles enter the market, DEF demand will increase. Initially many suppliers will oﬀer one to ﬁve gallon portable containers, or 55-gallon drums, but as market conditions grow, suppliers will transition to totes (approximately 250 continued on page 20 Petrogram | Summer 2009 | 19
