Transcription

1 National Fire Protection Association 1 Batterymarch Park, Quincy, MA Phone: Fax: MEMORANDUM To: From: NFPA Technical Committee on Solvent Extraction Plants Colleen Kelly, Administrator Technical Projects Date: August 19, 2015 Subject: NFPA 36 First Draft TC FINAL (F2016) According to the final ballot results, all ballot items received the necessary affirmative votes to pass ballot. 12 Members Eligible to Vote (Fawbush, Janz, Smith) 9 Affirmative on All Revisions (with comment; Barton) 0 Negative on one or more Revisions s on one or more Revisions The attached report shows the number of affirmative, negative, and abstaining votes as well as the explanation of the vote for each first revision. There are two criteria necessary for each first revision to pass ballot: (1) simple majority and (2) affirmative 2 / 3 vote. The mock examples below show how the calculations are determined. (1) Example for Simple Majority: Assuming there are 20 vote eligible committee members, 11 affirmative votes are required to pass ballot. (Sample calculation: 20 members eligible to vote 2 = = 11) (2) Example for Affirmative 2 / 3 : Assuming there are 20 vote eligible committee members and 1 member did not return their ballot and 2 members abstained, the number of affirmative votes required would be 12. (Sample calculation: 20 members eligble to vote 1 not returned 2 abstentions = 17 x 0.66 = = 12 ) As always please feel free to contact me if you have any questions.
