Dear Mr. Ryerson:
Assistant Secretary Bingham has asked me to respond to your letter dated July 6, 1977, requesting a variance from Section 1910.106(b)(2)(ii)(b) Spacing (Shell-to-Shell) Between Above-Ground Tanks, of the Occupational Safety and Health Standards.
Section 1910.106 is undergoing review in order to eliminate portions of the standard pertaining to property protection rather than employee protection. Included in this revision will be a modification of the shell-to-shell spacing requirement.
A Program Directive has recently been issued to the Occupational Safety and Health Administration (OSHA) field offices authorizing the use of a de minimis notice in situations involving a standard which is being modified, if the deviation from the present standard does not affect the safety or health of the employees. A de minimis notice carries no penalty and no abatement is required.
From the information contained in your application for variance, it appears that the present spacing of your tanks would not affect the safety and health of your employees and, would, therefore, be a de minimis situation. Accordingly, no further action will be taken on your variance application.
Any further questions you may have regarding this matter may be addressed to our Area Director, Mr. Robert A. Griffin, U.S. Department of Labor - OSHA, 2320 La Branch Street, Room 2118, Houston, Texas 77004. Telephone (713) 226-5431.
Sincerely,
James J. Concannon,
Director
Office of Variance Determination
