Sidenote, I was curious on what the safety reg is for pipeline valve safety and found the following:
https://www.phmsa.dot.gov/regulations/title49/interp/pi-12-0008
In a letter to the Pipeline and Hazardous Materials Safety Administration (PHMSA) dated August 9, 2012, the Associated Safety Consultants (ASC), Inc., requested an interpretation of the applicability of the Federal pipeline safety regulations at 49 CFR 192.317(b) to an aboveground gas transmission line or main. Specifically, ASC asks PHMSA's interpretation of how a 'safe distance' is defined or determined, and what would constitute an effective barricade?
Section 192.317(b) reads as follows:
(b) Each aboveground transmission line or main, not located offshore or in inland navigable water areas, must be protected from accidental damage by vehicular traffic or other similar causes, either by being placed at a safe distance from the traffic or by installing barricades.
PHMSA has not adopted general criteria to judge the safety of distances and effective barricades separating aboveground gas pipeline facilities from vehicular traffic. Therefore, a safe distance and effective barricade would be whatever a reasonable and prudent pipeline operator would conclude is safe under the site specific circumstances, considering relevant factors such as the speed limit, the direction of traffic, the terrain, and any natural barriers.
So there's no actual rules or regulations on what is required, just as long as it passes the gut check of the operator. The valve is 100 feet from a 50mph road (45 posted, but cmon its Houston yall), surrounded by gravel. A chainlink fence seems sub-par at best.
