Yes it can. In order to permit an OWTS design, EH staff must visit the property and verify that the soils/groundwater conditions are suitable and that all required setbacks can be met. Freezing temperatures and snow can prevent us from doing this. Generally, OWTS permits cannot be issued during the months of October – May.
If ground water is not checked during seasonally high groundwater, EH staff may conservatively assume shallow groundwater and require an OWTS design that is appropriate for high groundwater. Seasonal high groundwater is generally during May – June depending on elevation and weather. The ideal time to obtain an OWTS permit is in June. Consult with your designer or this office for more details.
