Operations involving the extraction of groundwater or springwater in lawful operation at the time this section originally becomes effective, and which meet the criteria for requiring review and approval by the Planning Board, may operate for a period of five years from the original effective date of this section without Planning Board approval. Existing operations, however, must submit to the Planning Board, within 90 days of the original effective date of this section, a map indicating the property from which groundwater is being extracted, showing the location of the extraction in relation to neighboring wells, surface water bodies, and property lines. Failure to submit the above map within 90 days results in the requirement to comply with all of these standards. Within 15 days of the original effective date of this requirement, the Code Enforcement Officer must notify, by certified mail, return receipt requested, the owners of all property which, to the best of his knowledge, contain existing operations, informing them of the requirements of this section.
