This cypress tree is allowed to grow up to a certain maximum height

There are 4×50m3 buried benzene tanks built in 2007; the tank area is rectangular, with four lightning rods 35 meters tall surrounding it. Poplar trees were planted on the edges of the tank area in 2006, and these poplars have now grown to several meters in height. I would like to ask whether these poplar trees must be cut down
Also, are there any standards that specify this?
The year before last, the safety inspection team came to our company for an inspection; when they arrived at the oil tank area, they said to those small pine trees, \"You cannot plant such trees here!\" Later, I tried to look up information on the topic, but couldn’t find anything. I think it must be because of the well-developed root system, which affects the buried oil tanks and oil pipes! I really hope someone knowledgeable can give a detailed explanation!
The Petrochemical Regulations seem to stipulate that oily trees, plants, and the like must not be grown within fire dikes; even if grass is planted, its height must remain below a certain level to prevent the accumulation of flammable gases.
Article 3.2.10 of the Fire Protection Design Code for Petrochemical Enterprises stipulates that the greening in the plant area shall comply with the following requirements: 1. Trees with high oil content should not be planted in the production area; it is advisable to choose tree species with high water content； II. Greenery or dense shrubs should not be planted between process units, or tank farms containing flammable gases, liquefied hydrocarbons, and flammable liquids, and the surrounding fire access roads ； III. Within the fire dike of flammable liquid tank farms, evergreen lawns with a growth height of no more than 15 cm and high moisture content can be planted ； IV. Greening is strictly prohibited within the fire dike of liquefied hydrocarbon tank farms ； V. The greening of the factory area should not hinder fire-fighting operations. Planting pine trees in the tank area on the third floor should be in accordance with the first point. Last edited by eleg on 2009-3-13 08:26.]
The cypress trees are outside the tank area; their height can be determined based on the height of the lightning rod.
Let me ask a related question: What are the height requirements for the landscape trees in the green belt of the dimethyl ether production area?
It mainly depends on how far the tree is from the tank, whether the coverage area of the lightning rod is sufficient to include the upper parts of the tree, and whether the tree’s roots affect the pipes inside the tank or its operational performance. Since cutting is mandated or required, in my opinion it’s best to do it early; safety measures should always be taken, as there’s no room for error when it comes to safety.
