be placed in a containment sump meeting the new performance standards?
Yes, the replacement STP will have to be placed in a containment sump meeting the requirements of the new performance standards including continuous interstitial monitoring using an electronic sump sensor or vacuum, pressure or hydrostatic interstitial monitoring methods. Question: To install a containment sump at the STP for an existing UST, I have to cut the pipe outside of the area where the containment sump will be located, install the sump, and then splice in a section of new pipe.
