psl195 (iii) An evidence from the evaluation strategies chosen and evaluation of hazard things regarded in creating the evaluation timetable.

Other than bottoms of aboveground breakout tanks, Every buried or submerged pipeline must have an exterior coating for external corrosion Regulate In the event the pipeline is—

(v) Other factors that affect the mechanistic properties associated with SCC together with although not restricted to working pressures, higher tensile residual stresses, and also the presence of sulfides.

(a) A steel pipeline Earlier Employed in service not topic to this portion qualifies to be used less than this part When the operator prepares and follows a composed technique to perform the subsequent:

(i) Steps for evaluating the prolonged-time period usefulness of ECDA in addressing exterior corrosion in pipeline segments; and

(a) Aboveground breakout tanks which were repaired, altered, or reconstructed and returned to company need to be able to withstanding the internal tension produced by the hazardous liquid to generally be saved therein and any anticipated exterior masses.

Lively corrosion means continuing corrosion which, Unless of course managed, could end in a ailment that's detrimental to community safety or the setting.

(iii) Conditions and notification strategies for virtually any modifications inside the ECDA program, which includes adjustments that influence the severity classification, the priority of direct assessment, and the time-frame for immediate evaluation of indications; and

length, diameter, functioning strain, or spot) of a pipeline can not be modified to accommodate the passage of the instrumented inside inspection gadget or the operator determines it will abandon or shut-down a pipeline as a result of the associated fee to comply with the prerequisite of this area.

implies a location where by three or more various critically imperiled or imperiled species or ecological communities, threatened or endangered species, depleted marine mammals, or migratory waterbird concentrations co-take place.

usually means the waters in the indicate superior water mark from the coast on the Gulf of Mexico and its inlets open up to The ocean (excluding rivers, tidal marshes, lakes, and canals) seaward to incorporate the territorial sea and Outer Continental Shelf to the depth of fifteen toes (four.six meters), as measured in the suggest lower drinking water.

(three) Corroded parts where the remaining wall thickness is below the minimum amount thickness necessary because of the tolerances within the specification to which the pipe was made.

(four) Ways that ought to be taken for general public basic safety while in the function of a hazardous liquid or carbon dioxide pipeline launch; and

The test stress for each strain take a look at done under this subpart should be taken care of all through the Component of the procedure being analyzed for a minimum of four continual several hours in a force equivalent to one hundred twenty five per cent, or even more, of the utmost working stress and, in the case of the pipeline that's not visually inspected for leakage in the exam, for a minimum of a further 4 continuous hours in a force equal to 110 p.c, or maybe more, of the utmost working pressure.
