I've reviewed all the DOT papers and guidance and interpertations on the demarcation where a DOT pipeline starts and where the OSHA/EPA regulated plant ends.
Heres what I get. We have a seperate overpressure protection system with a pilot operated valve that isolates the pipeline just upstream from the pig launcher. This is what we call the demarcation point, downstream of the valve built B31.8 maintained operated under DOT 195. Upstream build, inspected and maintained under B31.3 and OSHA/PSM & EPA/RMP
The local state DOT people say no, the pumps way back inside the plant create the pressure and therefore are covered under DOT 195 and all piping, maintenance and operations including OQ and DOT certified pump manufactures (OQ qualified) must be in place.
What say you?
