Vegetation management safety rules and regulations 

For public safety and electric system reliability, all electric utilities in California are required to prune or remove vegetation to maintain clearances for electric equipment, 包括电线, 输电塔和电线杆.

Here are some of the key requirements that apply to our vegetation management activities to remove electric shock hazards, reduce fire risk and help prevent power outages.

• California Public Utilities Commission (CPUC) General Order 95, 规则35

  GO 95, 规则35, requires an 18-inch radial clearance always be maintained between vegetation and high-voltage conductors (750 volts to 22,500伏).

  The clearance requirements increase for conductors carrying transmission voltages (69,(000伏或更高). GO 95，规则35，适用于整个可持续发展目标&E’s service area year-round, though certain state laws supersede 规则35 in 州责任区(SRAs).

• CPUC决定17-12-024

  在一个 2017年12月决定, the CPUC adopted new fire safety regulations, including a new standard requiring utilities to maintain a minimum of 4 feet of clearance between trees and power lines in high fire-threat areas. 2018年1月, the CPUC also approved a statewide Fire-Threat Map to help prioritize fire hazard areas and implement the new fire prevention rules. Maps detailing the High Fire-Threat District (HFTD) are posted online as part of an overview of the CPUC的消防安全程序.

• Public Resources Code (PRC), Section 4292

  This law is administered by the California Department of Forestry and Fire Protection, 被称为加州消防局. PRC 4292 requires a minimum clearance of 10 feet around the base of the pole cleared of all flammable vegetation down to bare soil. Limbs within the 10-foot radius are removed up to 8 feet above ground. All dead branches below the cross arms and within the 10-foot radius must be removed.

• Public Resources Code (PRC), Section 4293

  This law is administered by the California Department of Forestry and Fire Protection, 被称为加州消防局. PRC 4293 requires a 4-foot radial clearance always be maintained for conductors between 2,400伏和72伏,000伏. The clearance requirements increase as the voltage increases. PRC 4293 applies year-round in San Diego County areas designated as 州责任区(SRAs), where CAL FIRE is the primary fire suppression agency.

• Cal/OSHA, Title 8, Article 37

  This regulation is administered by the California Division of Occupational 安全 and 健康, 更广为人知的是Cal/OSHA. It states that no person shall come within 10 feet to 16 feet of energized high-voltage power lines, and that no boom-type lifting or hoisting equipment shall come within 10 feet to 20 feet, depending on the voltage of the high-voltage power lines.

  It also prohibits personnel and equipment from being in trees, 比如牛油果或其他果树, that are 10 feet or less from high-voltage power lines.

• 《全球知名十大博彩公司》第385条

  This law makes it a crime for any unauthorized person to use tools or other equipment within 6 feet of high-voltage lines.

• 联邦可靠性标准facc -003-4

  在一个ddition to meeting state requirements, utilities must meet 联邦可靠性标准 for clearances between vegetation and transmission lines. These standards for the nation's bulk-power system are set by the Federal Energy Regulatory Commission (FERC) and the North American 电 Reliability Corporation (NERC). The Transmission 植被管理 Reliability Standard, fac - 003 - 4, establishes a minimum clearance that must be maintained at all times between trees and transmission line rights-of-way. Federally required clearances vary depending on voltage and in some cases are less stringent than state standards.
