> can't do the necessary maintenance because it violates environmental laws about cutting down trees

In California, Pacific Gas and Electric is documented to make a business choice of relying on contractors to do the vast majority of tree removal and trimming after a certain change in the executive leadership. Subsequently, extensive documentation shows a chain of pressure to cut costs on tree trimming and extract better terms from the sub-contractors using harsh negotiation and policy.

Later, after catastrophic wildfires time and again in the last ten years, an avalanche of low-paid, low-skill tree cutting has occurred. In many cases the zeal to cut old trees seems to have some extra energy, between the abused sub-contractors, harsh labor oversight, insulated management and back-room executive management meetings.

The framing that it is environmental protections that are the impediment to power line maintenance is as worn thin as a floor carpet at a twenty dollar motel near Sacramento IMHO
