BASIS STATEMENT 

This rule reduces volatile organic compound (VOC) emissions from adhesives, sealants, adhesive primers and 

sealant primers by setting VOC content limits on approximately 40 adhesive, sealant adhesive primer and 

sealant primer products. Additionally, the rule allows for the use of add-on controls to meet the VOC limits. 

VOCs rea<-1 with nitrogen oxides in the presence of sunlight to form ozone, which is responsible for 

exacerbating a variety of respiratory ailments and may result in permanent lung damage. Products in these 

categories account for approximately 3.1 tons ofVOC emissions per day in Maine. 

In addition to the Basis Statement above, the Department has filed with the Se<--retary of State response to 

representative comments received during the comment period. "., "' ................. .. ........ -........ .......... ......................................... ...... -.. ~ .................. . .......... ··~ .................. ~ ................................................ '' 

BASIS STATEMENT FOR AMENDMENTS OF MAY 2014 

These amendments delay the compliance requirements for single-ply roof membrane installation or repair 

adhesives, single-ply roof membrane sealants and single-ply roof membrane adhesive primers until January 1 , 

2016; thereby addressing cross-border sales issue;,s with neighboring jurisdictions and reducing costs to the 

regulated community. There were no comments on the proposed amendments.
