English to Spanish Other Petroleum Eng/Sci

Hello!

I am translating a text for an Oil Company and I found this word.

I also found this information about class locations:

Class Locations

• (a) This section classifies pipeline locations for
purposes of this part. The following criteria apply to
classifications under this section.

– (1) A "class location unit" is an onshore area that extends
220 yards (200 meters) on either side of the centerline of
any continuous 1-mile (1.6 kilometers) of pipeline.

I understand what it is, but I don't know how to translate it to Spanish.

Could you please help me?

Thanks,

Mariana
