1. (1) Any person who believes that full compliance with 230 CMR 6.00 is overly burdensome may apply to the Office for a variance from 230 CMR 6.00. The burden is on the applicant to demonstrate in writing to the Office that the granting of the variance would not compromise public safety or otherwise undermine the purpose of 230 CMR 6.00. Applications for a variance shall be made in writing and shall contain such information as is required by the Office and shall be signed by the applicant. Unless otherwise required by law or as deemed appropriate by the Commissioner, the decision to grant or deny a variance request shall be based upon the applicant’s written submissions, 230 CMR 6.13 shall not be deemed to create a hearing requirement. Variances shall not waive the need to hold a license or permit.

   1. (a) Grant the application with whatever conditions are deemed appropriate; or
   2. (b) Deny the application.
