Section V:  Summary and Explanation of the Final Standard

Paragraph (d) General Requirements

*   *   * 

Overhead Electric Lines

At paragraph (d)(8)(i) of the final rule, OSHA is requiring that logging operations near overhead electric lines be done in accordance with the requirements of 1910.333(c)(3). The proposed rule repeated some of the requirements of 1910.333(c)(3). The pulpwood logging standard did not contain any provision regarding overhead electric wires. All State logging standards contain restrictions regarding felling near power lines.

One comment was received addressing minimum clearance from overhead lines (Ex. 5-34). This commenter suggested that when the line voltage is unknown and other information indicates that the line is obviously high voltage, a minimum clearance of 20 feet must be maintained from the line until the line voltage is established by the electrical system operator. The separation distance recommended by the commenter would provide clearance that would only be warranted by a 350 KV line. OSHA believes that maintenance of that great a separation distance is unnecessary in this rule. High voltage lines of this order of magnitude are usually on tall transmission towers, therefore it is highly unlikely any employee would come in contact with the line or have any means of getting near the line.

OSHA believes that 1910.333(c)(3) adequately spells out the precautions and clearances that must be taken when working near overhead lines. OSHA finds nothing indicating that logging is different from the rest of general industry, therefore, the Agency does not believe a special provision is necessary to address the logging industry.

At paragraph (d)(8)(ii) OSHA is requiring the employer to immediately notify the power company when any felled tree comes into contact with a power line. This provision also requires each employee to remain clear of the area until the power company advises there are no electrical hazards. OSHA has adopted this provision from the proposed standard. OSHA did not receive any comments on this provision.
