terminals & storage facilities are often secured 24 hours with lighting and staff on site. there is lots of aboveground structure including above ground pipelines, valves, electrical systems, flow measurement systems and large cylindrical storage tanks
pumping stations may or may not be staffed by security at night, and are usually fenced with 6-8 foot fencing topped with barbed wire. infrastructure also exists here, including above ground pipelines, valves, PIG traps, flow measurement and emergency shutoff buttons.
valves & densitometer stations are usually small & isolated, also with 6-8 foot chain link fencing & barbed wire. their enclosures have a gate entry, often secured with a standard key lock that can be cut with larger-sized bolt cutters and contain a small shack housing electrical sources and measurement equipment. valves have an additional link-chain wrapped around the hand wheel and stem, meant to prevent rotation.
integrity dig sites will be accessible via private property/stakeholder driveways or the right of way. they are sometimes marked with construction truck signs and flagging. notices for future digs are posted in the maintenance filings on the neb site.
right of ways are marked at road crossings by a small sign at the side of the road. It’s easy to find the closest crossing to navigate your way in to the site. Though identifiable in natural areas, ROW’s aren’t always easy to access and traverse swamps, river crossings, property lines etc. if you decide to go for a walk in these manmade mosquito breeding corridors you may have to jump some property fences to continue along your journey.
