pipes installed through interior floors that are in contact with the ground,

Intent | Intent 1: To limit the probability that soil gas extraction pipes
or their seals will be removed, or that the pipes will be used for purposes
other than soil gas extraction, which could lead to the infiltration of soil
gas (particularly radon) through an open extraction pipe, which could lead
to negative effects on the air quality of indoor spaces, which could lead
to harm to persons. |
