Intent | Intent 1: To limit the probability that the granular material installed
around soil gas extraction pipes will not be deep enough or cover a sufficient
area around the pipes, which could lead to the infiltration of soil gas (particularly
radon), which could lead to negative effects on the air quality of indoor
spaces, which could lead to harm to persons. |
