Voluntary Biodiesel Quality Specs
Passed to Address Clogged Filters New voluntary biodiesel specifications passed by the ASTM
D2 Committee on Petroleum Products and Lubricants were of- ficially sanctioned in July to strengthen controls for vegetable oils and animal fats used to create the alternative-fuel blend. Used in extreme climates, this blend can result in gelling. No. 1-B grade is the new blend operators can use along with
additives for filters that have been clogged by No. 2-B, the new designation for the current standard. Te National Biodiesel Board (NBB) said the No. 1-B and No. 2-B designations were selected to make the standard similar to the current mode of operation with No. 1 and No. 2 diesel fuel. “For the large majority of biodiesel users, the current standard
along with conventional industry management practices allow for biodiesel blend use year-round, even in extreme climates,” said Joe Jobe, CEO of NBB. Te No. 1-B grade was developed to address cases when the
new EPA-mandated Ultra Low Sulfur Diesel resulted in unex- pected filter clogging above the cloud point of the finished blend. Te NBB said this mostly occurred with low-aromatic No. 1-type diesel blends.
AASA Survey Shows Schools Have Strong Policies on Seclusion, Restraint In its latest survey on seclusion and restraint of special
needs students, the American Association of School Admin- istrators reported that more than nine out of 10 districts say they monitor students the entire time they are in seclusion. Te results were published in the second edition of “Keep-
ing Schools Safe,” a multi-part study on the behavior response procedures designed to protect the student and others dur- ing an emotional outburst. Te results indicate: • 94 percent of school districts monitor students in seclu-
sion at all times. • 97 percent of administrators end the use of seclusion
and restraint as soon as the emergency ends. • 97 percent of respondents say they never use mechani-
cal restraints on students. • 80 percent of all school personnel trained in the use of
seclusion and restraint are also trained in nonviolent inter- vention techniques. Te survey also reports that four of 10 superintendents
said the elimination of federal Safe and Drug-Free funding has made it “considerably more difficult” to fund profes- sional development training on positive behavioral support systems and nonviolent crisis intervention programs. Addi- tionally, 91 percent of respondents said their school district would benefit from funding to implement such programs.
